Abstract
An examination experiment has been carried out to investigate whether fingerprint powder and lifting technique can recover and transfer latent fingerprints from human skin surfaces of dead bodies. For recovery Swedish Black powder and for transfer White Fingerprint Gelatine were used.
Donors placed fingerprints on the human skin surfaces. Finger marks were then in all cases recovered with Swedish Black powder. The procedure was repeated after 2, 3, 4 and 5 hours. Treated finger marks were secured and preserved as latent fingerprint evidence by lifting process. We recovered 8% finger marks suitable for further examination of all deposited samples on the human skin surfaces.

Introduction
Cutaneous metastases from abdominal malignancies are rare and have been reported in less than 5% of patients [1]. Furthermore, metastases in patients suffering from colorectal neoplasia are even rarer entity. Tan et al, among 2538 of the new cases of colorectal cancer over the period of 6 years, reported only 3 cases (0.1%) with cutaneous deposits [1]. Presentation varies from cutaneous or subcutaneous small nodules, rash or large fungating lesions [1-4]. Inevitably, their presence implies the disease progression, and poor prognosis with the reported survival between 1 to 34 months [2,3,5].
We report a case of an elderly patient who initially was thought to present with a simple skin infection. Subsequently, the patient was diagnosed with the moderately differentiated mucinous adenocarcinoma and required the right hemicolectomy. This case highlights that a high index of suspicion is recommended in an unresolving skin erythema.
Abstract
Metastatic gastric tumors (MGTs) mean the tumor cells that attack the stomach and grow there through blood vessel, lymph vessel, and other pathway, consistent with the primary tumor in phenotype, which are clinically uncommon, and information on MGTs is generally limited to single case reports. Here we present a clinical series of 8 cases with MGTs, in attention to discuss the clinical characteristics, diagnosis and treatment, and prognosis of MGTs. Our data showed that MGTs are rare, with a male predominance, and the cause of death was multiple organ metastases in most cases. Heterochromous MGTs showed a significantly better prognosis than simultaneous MGTs, and a long interval between initial radical excision of the primary tumor and appearance of gastric metastasis was found to be associated with good prognosis.

Abstract
Hepatic angiosarcoma is a rare tumour that is often difficult to diagnose. Historically, most cases of hepatic angiosarcoma were seen in the setting of industrial epidemics caused by exposure of workers to toxins such as vinyl chloride. Cases associated with recognised exposure to carcinogens have fortunately been extremely rare for the last three or more decades. However, the tumour has by no means disappeared in the Australian community. In this case series, we describe three cases of hepatic angiosarcoma that were seen at our institution since 2002. The first case presented with cholestatic liver function tests and was found to have angiosarcoma on liver biopsy. In the second case, the patient was admitted for decompensated liver disease on a background of presumed hepatitis B cirrhosis. The diagnosis of hepatic angiosarcoma was made only at autopsy after the patient died from multi-organ failure. The third case presented with ascites and the diagnosis of disseminated angiosarcoma was again made at autopsy following a negative ante-mortem liver biopsy.
Abstract
A small set of amphetamines has been analyzed by gas chromatography (GC) high-resolution time-of-flight mass spectrometry (TOFMS) using a microplasma photoionization (MPPI) soft-ionization source. This plasma-based, wavelength selectable ionization source enables ionization of the test compounds and their corresponding derivatives at ~8-12 eV that is a softer alternative to electron ionization at 70 eV. Three plasma gases were used in this study: Xe plasma that emits photons at resonance lines of 9.57 eV and 8.44 eV; Kr plasma at 10.63 eV and 10.02 eV, and Ar plasma at 11.82 eV and 11.61 eV. Derivatization of the test compounds with trifluoroacetic anhydride and α-methoxy-α-(trifluoromethyl)-phenylacetyl pyrazole was evaluated because the MPPI mass spectra of the underivatized amphetamines yield primarily iminium ions, which make the identification of the test compounds by GC-TOFMS inconclusive. The MPPI mass spectra of the TFA-derivatized amphetamines yield abundant molecular ions, when using Xe as plasma gas, and enough fragment ions with the Ar plasma that can help in formula generation. The structure elucidation of two "known unknowns" designer drugs using this "tunable" soft-ionization source and a high-resolution TOF mass spectrometer is presented in this study.

We report the case of a 74 year old female who presented with imaging concerning for an intramural hematoma of the ascending aorta. Despite multiple imaging modalities consistent with intramural hematoma, operative findings confirmed a peri-aortic lymphoma or what was once lymphoma.
Abstract
This case report describes the diagnosis and management of a large mesenteric cyst in a 55 year old lady who presented with abdominal distension & with mass in the left upper quadrant. Mesenteric cysts are rare, benign, abdominal tumors to which <1000 cases have been reported in the literature. While 40% of cases are incidental findings found either through physical examination or imaging, they can cause non-specific abdominal symptoms including pain, altered bowel habits, nausea/vomiting or anorexia. Less commonly, 10% of cases can present with bowel obstruction, volvulus, torsion or shock. In general, the lack of characteristic clinical and radiological features presents as a diagnostic difficulty.
The mainstay in imaging is computerized tomography (CT). CT identifies and helps aid the decision to pursue a laparoscopic or open laparotomy approach, where complete surgical resection is the ultimate goal. In our patient a CT Abdomen & Pelvis showed a large, loculated cystic mass measuring 30cm in cranio-caudal length and 16cm in the transverse and anterior/posterior diameter. While different approaches have been described in the literature to surgically resect such cysts, our approach was largely reflective of size and adherence to surrounding structures in this case. A laparotomy was performed using an upper mid-line 7 cm incision; 4500cc of fluid was aspirated from the cyst which was found to originate from the small bowel mesentery. A complete resection of the multi-loculated cystic sac was done that included the resection of the middle mesenteric vein. The post-operative period was uneventful. The patient was discharged on post-operative day 2. The Histopathology identified the mass as a multi-loculated peritoneal inclusion-type cyst.
Abstract
In response to the rapidly rising intravenous opioid abuse epidemic, the United States Food and Drug Administration is currently promoting the development of prescription opioid tablets that are specifically formulated to deter abuse. Opana ER®; (Endo Pharmaceuticals) recently underwent reformulation to include a crush-resistant coating. Only recently described, illicit intravenous injection of reformulated Opana ER®; is associated with a distinctive clinical syndrome of thrombotic microangiopathy. Ten patients with the appropriate history and presenting symptoms were identified within an 8 month interval (July 2012 through February 2013) at the University of Tennessee Medical Center (UTMC) Knoxville with ICD-9 code of 446.6 (thrombotic microangiopathy) by electronic search. Review of laboratory data, electronic medical records, blood product usage, and total hospital admission charges were compiled for these individual patients. We report the clinicopathologic findings and correlating laboratory data for a group of patients presenting with thrombotic microangiopathy and documented recent history of intravenous Opana ER®; injection. We also report the economic impact and effect on blood product utilization by this study group.
Bone marrow transplant (BMT) recipients often require parenteral nutrition (PN) to meet their nutrient needs. While general guidelines for the provision of PN support by nutrition support teams (NSTs) have been shown to decrease inappropriate PN use, recommendations for nutrition in BMT recipients are lacking. We reviewed the charts of patients status post BMT on PN to determine whether institutional guidelines for PN initiation and continuous supervision of NSTs could be applied in this population. With the Institutional Review Board (IRB) approval, charts of adult BMT recipients on PN between June 14, 2006 and June 30, 2007 were examined. Sixty-nine charts were reviewed. Indications for initiation of PN included severe mucositis, graft versus host disease (GVHD), and other transplant related side effects resulting in poor oral intake. Among 69 patients, 37 (54%) had severe mucositis, 12 (17%) had GVHD, 2 (3%) had both mucositis and GVHD, and 18 (26%) had other side effects. It was determined that all patients met the criteria for initiation of PN support, as outlined in the guidelines form. Comprehensive guidelines for initiating PN support, developed by NSTs can also be used for BMT recipients in order to optimize their nutritional status.
Abstract
Background: Olfactory neuroblastoma is a rare malignancy of the nasal cavity.
Methods: We describe a case of radiation-induced olfactory neuroblastoma in a patient with a history of radiation for Graves' ophthalmopathy. We also reviewed the literature and found four other cases of radiation-induced olfactory neuroblastoma reported since 2000, suggesting prior radiotherapy as one risk factor for this disease.
Results: We treated the patient with multimodality treatment consisting of surgery, radiotherapy and chemotherapy (6 cycles of cisplatin/ etoposide). Despite the previously irradiation, treatment was well tolerated without excessive short or long term radiation toxicity. The patient remains in long term remission with no evidence of loco-regional recurrence or systemic metastasis after 12 years of follow-up.
Conclusions: Prior radiotherapy appears to be a risk factor in a handful of cases of this rare malignancy. Although the literature is limited for radiation-related olfactory neuroblastoma, outcomes appear generally poorer for this group but highly variable. With careful patient selection, aggressive multi-modality therapy including post-operative radiotherapy may be feasible.
Abstract
The synthetic cannabinoid, N-(1-adamantyl)-1-pentyl-1H-indazole-3-carboxamide, known also as AKB48 and/or APINACA, has been detected for the first time in herbal incense seized in Italy. Its structural characterization has been performed through gas chromatography-mass spectrometry (GC-MS) and high-resolution nuclear magnetic resonance (NMR) analysis. In order to favor an easier and faster identification of AKB48 in future investigations, NMR assignments in deuterated methanol and chloroform is also reported.

Case reports and studies may be defined as the non-experimental description of an individual or a few of cases in terms of new or unusual presentation of the diseases, an unexpected disease course or pathophysiology, and new effects (either beneficial or detrimental) of existing medications or procedures. Although they suffer from the non-experimental nature and other potential bias and errors, case reports and studies have played and will continue to play an important part in the advancement of medicine. They often serve as "primers" leading to discoveries of new diseases/disease pathophysiology as well as development of new preventive and therapeutic measures. Case reports and case studies are also employed as a platform for the training of medical students and/or resident doctors in scientific writing and critical thinking. Although the significance of case reports and studies in medicine has being recognized since the early stage of development of clinical medicine, their value needs to be appreciated in the context of modern clinical research design and the hierarchy of strength of evidence for guiding patient care. This paper discusses case reports and studies within the big picture of clinical research, research design, and evidence-based practice.

Abstract
The objectives of this retrospective study were 1. To determine the effect of three surgical techniques (right flank omentopexy, right flank omentoabomasopexy, and left flank abomasopexy), and 2. To determine the effect of concurrent disease on return to normal milk production. Return to normal milk production occurred in 86.3% of cows diagnosed with LDA. Results suggested that cattle diagnosed with LDA corrected via right flank omentopexy or left flank abomasopexy were significantly more likely to return to normal milk production as compared to those corrected via right flank omentoabomasopexy (p< 0.02). No significant difference in return to normal milk production was noted between surgical techniques for correction of RDA (p=1.000) and right abomasal volvulus (p=0.596). Concurrent disease diagnoses did not affect return to milk production. Reported complications were infrequent (n=11).

Causes for syncope are multifaceted. Hormonal etiology, specifically hypothyroidism, is associated with cardiac arrhythmias [1]. Sinus bradycardia, low voltage, nonspecific T-wave changes and dissociative atrioventricular (AV) abnormalities are some of descriptive electrocardiographic features [2]. In the majority of well know clinical presentations complete AV block requires the insertion of a permanent pacemaker. However hypothyroidism related bradycardia and consequential symptomatic AV blocks could be reversible with timely and proper management.
We report a case of severe hypothyroidism resulting in insertion of transient pacemaker with favorable clinical course and fully reversible complete AV block after accordant pharmacological hormonal substitution.
The Infanticide: Some Forensic and Ethical IssuesAnnex Publishers
Abstract
Forensic investigation and clinical treatment of infanticide mother is an occasion to reflect about the social stigma associated with this crime. The forensic-psychiatric assessment must be anchored on an authentic and meaningful clinical relationship to criminal mother, without misinterpretation and countertransferal dynamics, such as emotional reactions of mistrust and stigmatization of the offender. These prevent the evaluator from making a correct psychological and psychopathological diagnosis. There is evidence that diachronic, multidisciplinary diagnostic evaluation may lead to strategies for treatment and rehabilitation. These measures, which can allow the patient to regain his dignity, his working capacities and social role, and ensure that the penalty is rehabilitative and not only retributive.
Forensic investigation involves the collecting, assembling, and analysis of all crime-related evidence with the aim of getting to a conclusion about a suspect. Humans have microorganisms present in the gut, mouth, and skin, unique to each individual. Individual microbiome can be distinguished based on the bacterial 16S rRNA to tell the bacterial species diversity between and among persons. Sterilized swab-sticks were used to sample fifteen individuals’ fingertips, their personal items, office doorknob and a college photocopier. Skin-associated bacteria were readily recovered from surfaces and the structure of these bacterial communities can be used to link individuals to the objects they had touched. We compared the bacterial communities on objects and skin to match the objects to the individual. The 16S rRNA gene PCR polymorphism was used to analyze the bacterial community for each person and object. The higher similarity of bacterial community between individuals’ and personal laptop keyboards, office chairs and office member’s fingertips were evident than between the doorknob and the photocopier. Highest bacterial species diversity was observed in doorknob followed by the photocopier. Hence, an individual’s bacterial profile can be used as a human identification tool alongside other tools in forensic fields especially in cases where there is evidence of deficiency.
Key-words: Microbial signature, Forensics, 16S rRNA, Individual person, Skin bacteria, Fingerprint
As technology infiltrates every aspect of our lives its no wonder solving crimes has become futuristic in its advances.
The benefits of real-time on-site forensic investigations are manifold and such technology has the potential to strongly increase the speed and efficacy of the criminal justice system.

These measures, which can allow the patient to regain his dignity, his working capacities and social role, and ensure that the penalty is rehabilitative and not only retributive.
Forensic investigation involves the collecting, assembling, and analysis of all crime-related evidence with the aim of getting to a conclusion about a suspect. Humans have microorganisms present in the gut, mouth, and skin, unique to each individual. Individual microbiome can be distinguished based on the bacterial 16S rRNA to tell the bacterial species diversity between and among persons. Sterilized swab-sticks were used to sample fifteen individuals’ fingertips, their personal items, office doorknob and a college photocopier. Skin-associated bacteria were readily recovered from surfaces and the structure of these bacterial communities can be used to link individuals to the objects they had touched. We compared the bacterial communities on objects and skin to match the objects to the individual. The 16S rRNA gene PCR polymorphism was used to analyze the bacterial community for each person and object. The higher similarity of bacterial community between individuals’ and personal laptop keyboards, office chairs and office member’s fingertips were evident than between the doorknob and the photocopier. Highest bacterial species diversity was observed in doorknob followed by the photocopier. Hence, an individual’s bacterial profile can be used as a human identification tool alongside other tools in forensic fields especially in cases where there is evidence of deficiency.

1. Explain the proper collection and packaging methodologies for biological evidence. Why should biological evidence never be packaged in air-tight or non-breathable mediums?
The proper collection and packaging methodologies for biological evidence is important for investigators to follow in order to properly preserve evidence and not allow it to be contaminated. First, to explain what biological evidence is classified as, we will describe a few of the different specimens. Blood, saliva, or semen are common types of bodily fluids that can be retrieved at a crime scene. In order to properly contain these specimens, investigators will use a cotton swab that is encased in a plastic cover to protect the swab from being contaminated and they label where and when the located the specimen (Plaza, 2016). Fingerprints or teeth marks are other forms of biological evidence. These can be lifted using adhesives that can pull the print from the piece of evidence. If the adhesive will destroy the evidence, then the investigator will take a photograph of the dusted print and use this to examine in the lab. Teeth marks can be copied using a type of plaster that will fill the cavity left by the bite. This can be compared to dental records (Dorion, 2011).
Storing biological evidence is complicated because if you store it in air-tight container can damage the evidence by allowing it be effected by outside temperatures that can cause bacteria to grow on the evidence if not allowed to breath. Keeping the material in a dry location with a controlled temperature can preserve the evidence for a longer period of time. Not allowing the evidence to be stored properly can also cause the evidence to dry up and no longer be useful. Once DNA is damaged, it cannot be replicated or repaired (Lee, 2011).
2. What is PCR analysis? Why is this application important particularly for cold cases or cases in which only a small amount of DNA is recovered?
PCR is Polymerase Chain Reaction and is a test that replaced the Restriction Fragment Length Polymorphism test in the late 1990s (Minor, 2013). This test I able to develop a DNA sample and profile from biological evidence that was once deemed extremely small (DOJ, 2002). This test is able to do so by copying the DNA and reproducing it without causing damage to the original piece of evidence. This process is very important to cold cases because investigators have the ability to reconstruct DNA from evidence that may have previously been deemed damaged. When DNA evidence is damaged or only a small amount remains, this test can help investigators piece together the events and possibly assist in solving the cold case.
3. What is STR analysis? Why is this an effective method for DNA typing?
STR analysis is Short Tandem Repeat technology that can evaluate a specific region of DNA (DOJ, 2002). This test is able to compare DNA samples and identify the matching profile against ...

Anti arthritic-efficacy-and-safety-of-crominex-3+(trivalent-chromium-phyllant...Annex Publishers
Abstract
The present investigation was undertaken to evaluate the therapeutic efficacy and safety of Crominex® 3+ (a complex of trivalent chromium, Phyllanthus emblica (Amla) extract and purified Shilajit) in moderately arthritic dogs. Eleven client-owned moderately arthritic dogs in a randomized double-blinded study received placebo or Crominex® 3+ twice daily for a period of 150 days. On a monthly basis, each dog was evaluated for arthritis associated pain (overall pain, pain upon limb manipulation and pain after physical exertion) and a full physical exam (body weight, body temperature and heart rate). At the same time intervals, dogs serum samples were examined for biomarkers of kidney (BUN and creatinine), liver (bilirubin, ALT and AST) and heart and skeletal muscle (CK) functions. Findings of this investigation revealed that dogs receiving Crominex® 3+ (1000 μg chromium, 15 mg Amla extract and 15 mg purified Shilajit per day in two divided doses) exhibited a significant (P< 0.05) reduction in arthritic pain noted as early as after 90 days with a maximum reduction after 150 days of treatment. Pain level remained the same or slightly increased in the dogs receiving placebo. No significant change occurred in physical parameters or serum biomarkers in dogs on placebo or Crominex® 3+, which suggested that Crominex® 3+ was well tolerated by arthritic dogs. In conclusion, Crominex® 3+ significantly (P< 0.05) ameliorated arthritic pain and improved quality of life without causing any untoward effects in moderately arthritic dogs.
Abstract
Salmonella is a causative agent for a wide variety of pathological diseases in humans, cattle, poultry and other farm animals and hence Salmonella infections are a major cause of concern to humans, veterinary animals and to food industry. With characterization of over 2500 Salmonella serovars, the pathogen nearly infects all vertebrates but the severity of infection varies from one serovar to another depending upon their host specificity. Some Salmonella serovars are restricted to one or few hosts while others have a broad host spectrum. Thus the understanding of the mechanisms involving host preference by one serovar over another is very important. As our knowledge about host adaptability will then be instrumental in designing better vaccines. Furthermore, methods involving identification of genetic markers for host specificity will prove to be instrumental in determining virulence factors for other pathogenic bacteria that cause systemic infections.

Abstract
The objective of this investigation was to evaluate the efficacy and safety of purified Shilajit in moderately arthritic dogs. Ten client-owned dogs in a randomized double-blinded study received either a placebo or Shilajit (500 mg) twice daily for a period of five months. Dogs were evaluated each month for physical condition (body weight, body temperature, heart rate, and respiration rate) and pain associated with arthritis (overall pain, pain from limb manipulation, and pain after physical exertion). Serum samples collected from these dogs were examined each month for biomarkers of liver (bilirubin, ALT, and AST), kidney (BUN and creatinine) heart and muscle (creatine kinase) functions. The findings of this study revealed that dogs receiving Shilajit (Group-II) showed a significant (P< 0.05) reduction in pain from limb manipulation by day 60, and overall pain and pain after physical exertion by day 120. Maximum pain reduction, using all three criteria, was observed on day 150. Pain level remained significantly unchanged in dogs receiving the placebo. Dogs in either group showed no significant change (P>0.05) in physical parameters or serum markers, suggesting that Shilajit was well tolerated by moderately arthritic dogs. It was concluded that Shilajit significantly (P< 0.05) reduced pain in osteoarthritic dogs and markedly improved their daily life without any side effects.

Abstract
Human origin determination is an important aspect of blood grouping analysis in forensic science laboratories. In the present study, protein extractants like gel buffer, ammonia and saline employed for origin determination were evaluated and compared qualitatively and quantitatively for their role in the extraction of proteins from dried blood stained materials of human origin at regular time intervals. Qualitative and quantitative methods employing counter immunoelectrophoresis (CIE) and rocket immunoelectrophoresis (RIE) respectively were used to study the protein extraction efficiency of extractants. Ammonia, compared to gel buffer and saline extracted the proteins effectively. Maximum extraction of proteins was observed in 2-3 hours of sample. CIE demonstrated sharp precipitin bands with all samples of ammonia extractant compared to the samples of counterparts. RIE also revealed greater concentration of proteins in the ammonia extract compared to extracts of gel buffer and saline. These results provide evidence that ammonia serves as a better protein extractant for rapid determination of human blood origin.

Abstract
A person's stature is an identifying characteristic that is often used in forensic investigation. Footprint is the one of the valuable physical evidence encountered in the crime scenes and examination of barefoot impressions is important especially in developing countries like India, Malaysia where majority of the rural population like to walk barefooted because of socio-economic and climatic reasons. Foot impressions are still found at crime scenes, since offenders often tend to remove their footwear either to avoid noise or to gain better grip in climbing walls, etc., while entering or exiting. Most of the foot/foot print studies were conducted on mixed population. The researchers have cautioned that the people from different races and regions of a country bear different morphological features depending upon their geographical distribution and primary racial characteristics and hence a single formula cannot represent all parts of that country or world. The present study aims to estimate stature from bilateral footprints collected from 320 (160 males, 160 females) consenting adult Ibans, an indigenous group residing in Sarawak state, east Malaysia. Informed consent and Human Ethical Approval were obtained. The height of the individuals and footprints were collected following the standard procedure. The data obtained were analyzed with PASW 20 computer software and derived regression formulae to estimate stature from footprint lengths of Iban ethnics. The result of the investigation revealed that all footprint lengths exhibit statistically positive significant correlation with stature (p< 0.001). Correlation coefficient (R) values are found to be higher in the pooled sample (0.861–0.887) when compared with males (0.753–0.789) and females (0.728–0.790). The regression formulae derived for the pooled sample can be used to estimate stature when the sex of the footprint remains unknown, as in real crime scenarios.
Abstract
Programming scripts were written for the statistical analysis of genetic data from simple cases and complex cases of undetermined paternity. The methods presented here involve algorithms constructed with R, an open-source and increasingly popular programming language used for calculations and statistics; these methods also involve conditional probability analysis, Bayes’ Theorem, and pedigree analysis. Previous computer programs for assessing probable paternity in complex cases of undetermined paternity have been written; however, only minimal or generalized formulas are described in the papers presenting these programs. Therefore, these previously published programs are difficult to understand for most forensic researchers. Here, we present the details of the calculations used to evaluate probabilities of paternity and the details of the R scripts used execute these calculations. These scripts were constructed not only for standard trio case where DNA typing of the mother, child, and the alleged father are available, but also for more complex cases where DNA typing of the alleged father is absent. In these more complex cases, the putative genotype of the alleged father is determined from the genotypes of his parents, his siblings, his wife, children known to be his biological children, or some combination of these people. This report provides concrete and orderly descriptions of the calculations and the R scripts so that each facet of this method is easily understood. Furthermore, access to these scripts will enable individual researchers to develop calculation systems of their own.

Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

Crime scene investigation is a process that aims at recording the scene as it is first encountered, and recognizing and collecting all physical evidence potentially relevant to the solution of the case. Crime scene investigators who have received comprehensive forensic training usually quickly take over the work at the scene and implement ideas from research institutes in practice. The personnel processing crime scenes should be aware of equipment necessary to process a crime scene and a mechanism to secure and transport the evidence to the laboratory. Physical evidence has the potential to play a critical role in the overall investigation and resolution of a suspected criminal act. We can therefore say that in investigating crimes, we are using traditional investigative approaches with modern methods and “state of the art” tools.
The examination of latent fingerprints involves several steps, progressing from simple to increasingly sophisticated. Most fingerprints are hidden until revealed by chemicals (powder, liquids or gases). Once a print has been revealed, it is usually study or “lifted” and transferred to a laboratory. Scientists have developed more than 40 methods of retrieving fingerprints from crime scenes [1]. In our article we will focus on a method of fingerprint recovery from human skin by finger powder.
ISSN: 2348-9804
At the crime scene the finger marks may be found on many surfaces, including glasses, woods, papers, metals, fruits, vegetables and human skin. According to forensic literature human skin is one of the least convenient surfaces for recovering ridge skin impressions [2]. Hebrard and Donche [3] achieved positive results of finger mark recovery from human skin. They were using several methods include RTX method [4], powders [5-7], iodine fumes [6,7] and CA fuming [8]. The detection was done on surfaces of 16 living persons and 23 dead bodies. Delmas [9] presented the use of luminous magnetic powder. In his study intentionally deposited fingerprints on the skin of five victims were examined. Mashiko and Miyamoto [4] also achieved positive results of finger mark recovery from human skin.
This article is part of a study on fingerprints deposited onto human skin of dead bodies. It contains findings and results of recovery by fingerprint powder and gelatine lifter for finger marks on these surfaces. Materials and Methods
Donors placed fingerprints on the human skin surfaces. Finger marks were then in all cases recovered with Swedish Black powder. The procedure was repeated after 2, 3, 4 and 5 hours. Treated finger marks were secured and preserved as latent fingerprint evidence by lifting process. We recovered 8% finger marks suitable for further examination of all deposited samples on the human skin surfaces.
In this study Swedish Black powder for recovery of finger marks from human skin was used. Fingerprints were intentionally deposited on the skin surfaces of 10 dead bodies. At first, the dead body was described. Those records contained the circumstances of death, handling of the body, the time that passed from death to research, the body temperature, data about the cleaning the body and the autopsy, if any. The room temperature and relative humidity were measured too. Then a light source was used to visually

scan for finger marks on the surfaces prior of fingerprint deposition. No traces were detected. The site was labelled with an ordinal number with ruler. Fingerprints were deposited on the wrist area, neck area, straight and smooth skin surfaces of the dead bodies without hairy areas, heavily wrinkled and damaged parts of the body. During deposition of finger marks the contact time was between 3 and 5 s. Finger marks were then processed by means of Swedish Black powder. The latents were photographed and then lifted by White Fingerprint Gelatine. All of these tests were held at the department of pathology.
Photos and lifters of finger marks were examined in the forensic science laboratory.
All procedures were recorded by a Canon EOS camera and the fingermarks were examined by fingerprint experts using Adobe Photoshop 7.0 CE.
Finger mark examinations
Samples with developed finger marks were examined with a graphics program Adobe Photoshop 7.0 CE. Each recovered and secured (lifted) finger mark was graded into two groups as follows:
- finger mark suitable for further examination (an entire or a partial profile of friction ridge and at least 8 individual features can be observed) and
- finger mark of no use (less than 7 individual features can be observed).
All solvents, powder and lifter were purchased from the BVDA company (Bureau voor Dactyloscopische Artikelen).
Fingerprints on skin surface of dead bodies
Fingerprints were deposited by two separate volunteers onto ten dead bodies - 6 men and 4 women, aged 38 to 91 years. 7 bodies were previously refrigerated in the cold room of pathology department where the room temperature is between 5 and 7 0C. The air temperature in the pathology department and in the forensic laboratory was between 17 0C and 20 0C and the relative humidity level was around 60%.
Visual examination
This examination was used before any other recovery procedure. A crime scene forensic light source was used.
Lifting method
The lifting method used for the recovery of fingerprints from dead bodies was White Fingerprint Gelatine. Each of lifters was placed on the mark for at least 3 s. The White Fingerprint Gelatine is composed of a thick, non-aggressive and low-adhesive gelatine layer which makes it possible to lift finger marks, a carrier of linen rubber and a transparent polyester film used for protection. The white linen rubber backing is suitable for writing notes like date, case number, place of crime, etc.
Powder/brush
Swedish Black powder (100/250 ml) was used for detection as a physical method. The powder was applied to the examined area with a round fingerprint brush with squirrel hair.
The worksheets with tables for data entry and results of the investigations were used. Which part of the human skin surface was examined depended on the age, sex, body hair, and deformation of the skin of the dead body. We looked for the smooth and taut skin. Important were the skin surfaces that are most exposed to actions in cases of criminal offences, for example ankle, wrist, neck, chest and leg. Results and discussion
We investigated finger marks on the skin surfaces of human skin of 10 bodies. All together 150 fingerprints has been deposited on
different parts of the bodies.
In our study 12 finger marks suitable for further examination were recovered, which is 8% of the performance. Some of them are on Figure 1.
Finger marks recovered within one hour
By means of Swedish Black 6 samples of finger marks were usable for further examination. Finger marks were recovered on the chest, ulna, femur, shin (2 marks) and area of ankle.
Finger marks recovered between one and two hours
Two samples of finger marks were usable for further examination. Finger marks were recovered on the chest and ulna.
Finger marks recovered between two and three hours
Four samples of finger marks were usable for further examination. Finger marks were recovered on the ankle.
Between three and five hours no finger marks were recovered.

The most useful finger marks (6 finger marks or 4%) were recovered in the first hour after the time when the fingerprints were deposited on the human skin surfaces. The results in the second hour were less successful, only 2 finger marks (1.3%) were recovered. Between two and three hours 4 finger marks (2.7%) were recovered. In the follow-up examination no latents were detected. Negative results were probably the cause of the body condense. The bodies started heating up or cooling due to the temperature of the laboratory. On the human skin surfaces humidity was detected. It is clear that the fingerprint powder is not method for recovery of wet fingerprint latents. In such cases other chemical methods are recommended [2,3,4,7]. The least suitable surfaces were face, neck, shoulder, humerus, abdomen and wrist. The best results were on the ankles. In this study the temperature of human skin surface was the main reason for negative results. The temperature of skin was between 17 0C and 37 0C. In our circumstances the good condition for the recovery of latent fingerprints on human skin should be approximately equal body and laboratory temperature.
Powder dusting is the basic and least complicated method for the recovery of fingerprints from many surfaces, from human skin as well. In this study Swedish Black powder was used for the recovery of finger marks and White Fingerprint Gelatine was used for lifting. This study has shown that the best results were achieved for finger marks recovered within one and three hours after fingerprints were deposited onto human skin surfaces.
