ABSTRACT- The magnetosome is organelles of prokaryotic bacteria having a magnetic property, they are Magnetotactic Bacteria. MTB consisting of phospholipids bilayer bounded a magnetite crystal that contains the different set of proteins and functionally different. The magnetosome particles are potentially useful in the number of applications as a magnetic nanoparticle. In this work, we studied the localization and expression of proteins play an essential role in magnetosome biomineralization process by fluorescence microscopy and biochemical analysis in microaerophilic Magnetospirillum gryphiswaldense R3/S1. Although optimum conditions were mutually exclusive for high fluorescence and magnetite synthesis through this study, oxygen-limited growth conditions were established, which enhance magnetite biomineralization, growth, and formation of GFP fluorophore at reasonable rates. Through fluorescence microscopy and immunoblotting technique, we were studied that the subcellular localization and expression of magnetosome proteins i.e. GFP-tagged. Among MamC, MamF, and MamG magnetosome proteins fused to GFP, the strongest expression, and fluorescence displayed by MamC-GFP. The magnetosome tagged to MamC-GFP purified from cells shows strong fluorescence, shows stability towards wide temperature range and salt concentration however sensitive towards detergent. Our research exhibited the utilization of MamC as an anchor for magnetosome-specific display for fusions of the heterologous gene.

Streptococcus pyogenes (group A β-hemolytic Streptococcus (GABHS)) is the common cause of acute bacterial pharyngitis also known as strep throat or sore throat. Recorded cases of GAS bacterial pharyngitis are 15-36% in children and 5-15% in adults. School aged children in seasons of spring and winter harbor the bacterium up to 20% whereas this rate is much lower in adults. On a global scale, over 616 million new cases of GAS pharyngitis occur every year. Not only is this bacterium responsible for hundred millions of pharyngitis cases but also approximately 10,000 to 15,000 cases of invasive GAS cases are reported annually in the United States, accounting for 10% to 13% mortality rate (http://www.cdc.gov/ncidod/dbmd/abcs/forinvasiveandnoninvasivediseaseincidence). Acute infections can lead to rheumatic fever and post-streptococcal glomerulonephritis (kidney inflammation), which distress children worldwide with disability and death, if antibiotic treatment fails or if the disease is left unattended. Rheumatic fever and rheumatic heart disease are known to be the leading causes of cardiovascular death during the first five decades of life in underdeveloped countries mainly concerning children. Tissues contributing to the GAS nosocomial infections are upper respiratory tract, skin, vaginal and anal area, although latter cases are rare.
GAS has several surface proteins and produces numerous extracellular products that facilitate permeation and successive evasion of the host’s immune system. Streptococcal pharyngitis results from the proliferation of GAS in the pharynx. Virulence associated factors enable S. pyogenes to attach to host tissues, elude the immune response, and spread by penetrating the host tissue layers followed by colonization.

On the Modulation of Biocompatibility of Hydrogels with Collagen and Guar Gum...IIJSRJournal
In this work, we report the synthesis of molybdenum metal-organic frameworks (Mo-MOFs) using 1,3,5-benzenetricarboxylic acid and the amino acids L-phenylalanine, L- tryptophan, and L-histidine as ligands. They were incorporated in hydrogel matrixes comprised of collagen and guar gum to obtain composite hydrogels. The effect of chemical structure of Mo-MOFs on the structure, physicochemical properties and in vitro biocompatibility of hydrogels was studied. These biomaterials showed a super absorbent performance (higher than 2000 ± 169%) and a high degree of reticulation (higher than 75 ± 6%). The microstructure of the composites showed a granular morphology with some porosity. These composites were degraded entirely by hydrolysis at pH 5 and pH 7 at room temperature in time lapses shorter than 15 days. Also, they were biocompatible with porcine dermis fibroblasts not showing cytotoxic effects up to 48 h of incubation allowing its proliferation, and it was observed that the MOF containing L-tryptophan improved notably the biocompatibility of the collagen/guar gum matrix. Finally, the matrixes were tested as vehicles for cell encapsulation and release. The slow-release rates show that fibroblasts tend to remain inside the hydrogel matrixes. Thus, these materials are more suitable for cell scaffolds and tissue engineering applications such as wound healing dressings.
Genipin cross-linked electrospun chitosan-based nanofibrous mat as tissue eng...Nanomedicine Journal (NMJ)
Objective(s):
To improve water stability of electrospun chitosan/ Polyethylene oxide (PEO) nanofibers, genipin, a biocompatible and nontoxic agent, was used to crosslink chitosan based nanofibers.
Materials and Methods:
Different amounts of genipin were added to the chitosan/PEO solutions, chitosan/PEO weight ratio 90/10 in 80 % acetic acid, and the solutions were then electrospun to form nanofibers. The spun nanofibers were exposed to water vapor to complete crosslinking. The nanofibrous membranes were subjected to detailed analysis by scanning electron microscopy (SEM), Fourier transform infrared-attenuated total reflection (FTIR-ATR) spectroscopy, swelling test, MTT cytotoxicity, and cell attachment.
Results:
SEM images of electrospun mats showed that genipin-crosslinked nanofibers retained their fibrous structure after immerging in PBS (pH=7.4) for 24 hours, while the uncrosslinked samples lost their fibrous structure, indicating the water stability of genipin-crosslinked nanofibers. The genipin-crosslinked mats also showed no significant change in swelling ratio in comparison with uncrosslinked ones. FTIR-ATR spectrum of uncrosslinked and genipin-crosslinked chitosan nanofibers revealed the reaction between genipin and amino groups of chitosan. Cytotoxicity of genipin-crosslinked nanofibers was examined by MTT assay on human fibroblast cells in the presence of nanofibers extraction media. The genipin-crosslinked nanofibers did not show any toxic effects on fibroblast cells at the lowest and moderate amount of genipin. The fibroblast cells also showed a good adhesion on genipin-crosslinked nanofibers.
Conclusion:
This electrospun matrix would be used for biomedical applications such as wound dressing and scaffold for tissue engineering without the concern of toxicity.

Microbial Production Of Alkaline Proteases And Evaluation Of Its Performances...Shafkat Shamim Rahman
A high alkaline protease producing bacterial strain was isolated and identified a local soil sample. The organism was gram positive and forms spore during adverse condition in the growth medium. After various tests it was suggested and the features agreed with the description of Bacillus subtilis. It was also identified as B. subtilis with 99.9% identity by API 50 CHB. The enzyme hydrolyses a number of proteins including azocasein which suggests that it is an extracellular alkaline protease. The experimentally determined isoelectric point was 5.1 and the optimal enzyme activity was at 60°C and at pH 8.5. The esterase preferentially hydrolyzed short-chain fatty acids. Native enzyme preparations typically showed a Michaelis constant (Km) and Vmax of 0.40mM and 12,200 U mg)-1, respectively. This microbial enzyme was partially purified by ammonium sulfate fractionation, dialysis, DEAE cellulose chromatography and electrophoretic analysis. Enzyme purity was tested by SDS-PAGE. Quantitative estimation has shown that 40mL of culture supernatant could dehair 2×1 cm of leather completely in 9 hours. In future the tanneries will use a combination of chemical and enzymatic processes. In practical applications, protease is a useful enzyme for promoting the hydrolysis of proteins and showing significant industrial applications.

Background: One of the most common disorders in this age group, abnormal uterine bleeding (AUB), is the primary cause of most gynaecological problems in adolescents. Unfortunately, epidemiological data on AUB in teenagers is scarce, especially in the Indian subcontinent. The PALM-COEIN classification, where PALM stands for structural reasons and COEIN for functional causes, was employed in this single-center prospective observational study to evaluate the relative contributions of several etiological factors in AUB. To comprehend the etiological, dermographic, and therapeutic factors affecting menorrhagia in patients going through adolescence. Methods: Enrollment for females with AUB between 10 and 19 occurred between January and December 2022. A thorough history, physical examination, and laboratory evaluation, which in every case comprised standard testing, hormone analysis, and abdominal and pelvic ultrasonography were used to determine the cause of AUB. MRIs and CT scans were performed when needed. Results: There were 190 patients enrolled in total. Functional factors comprised the predominant aetiology of AUB among adolescent females: Adenomyosis=01 (0.52%), Polyp=1 (0.52%). Coagulopathy=2 (1.05%), Leomyoma=01 (0.52%), Malignancy=1 (0.52%), and PALM=4 (2.11%). COEIN=186 (97.89%), ovulation disorder=175 (92.15%), endometrial=01 (0.52%), iatrogenic=6 (3.15%), non-specified=2 (1.05%), and iatrogenic=6 (3.15%). Conclusion: The most frequent cause of AUB in the adolescent population is ovulatory abnormalities. Even though they are extremely rare, structural factors must be ruled out. A helpful technique for evaluating patients with AUB systematically is the PALM-COEIN classification.

Background: A 51-year-old woman had left lower abdomen pain for 18 hours with nausea and vomiting. Prior CT scans suggested pelvic neoplasms. Our hospital's emergency CT showed an enlarged uterus with cystic shadows, right adnexal cysts, and stomach fluid. Physical examination revealed left lower abdomen discomfort. A gynaecological examination revealed a painful, firm pelvic mass of 151210 cm. Further diagnosis is underway. Method: The patient underwent emergency exploratory laparotomy, discovering a twisted, swollen left ovary with a 540° rotation, classified as a benign cyst. It was found that the patient had congenital upper vaginal atresia and bilateral initial uteri. Pain was reduced after surgery, thanks to symptomatic treatment. An abnormal karyotype of 46, XX,1qh+ was found during genetic testing. Result: Fallopian tubes, uterus, and vagina develop from the embryonic accessory mesonephric duct. MRKH syndrome is caused by bilateral accessory mesonephric duct dysplasia and disappearance of the uterus or vagina. MRKH has three types, with Type 1 lacking uterus or vagina. Due to ovarian cyst torsion, this Type 1 MRKH with double initial uterus and upper vaginal atresia needed left adnexa resection. Genetic testing showed a typical female karyotype. MRKH's complex aetiology incorporates chromosomal abnormalities, emphasizing early cytogenetic evaluation for personalized treatment and fertility assistance. Conclusion: Early cytogenetic testing for MRKH syndrome patients is crucial for determining the underlying cause and guiding personalized treatment plans to restore reproductive function and improve quality of life.

Background: Chemical changes occur in the epididymis when the testicular sperm grows. When sperm and seminal fluids mix during ejaculation, a substance called semen is formed. The cervical mucus of a fertilized egg screens out the best possible sperm. For infertility, Intra Cytoplasmic Sperm Injection (ICSI) can be necessary. Test sperm that are DNA efficient, normal, and motile using Swim Up. Sperm could be damaged by reactive oxygen species that are produced during centrifugation. All infertility treatments should take these factors into account. Methods: The in vitro fertilization (ICSI) procedure was administered to fifty male patients who were 35 years old or younger and tested positive for normozoospermia, asthenozoospermia, and oligozoospermia. After obtaining informed consent, a Swim-Up was performed using both the full semen and a washed pellet. With sperm obtained from both methods, six Metaphase-2 stages of oocytes (MII oocytes) were implanted in each patient. A Tri-gas Bench-top incubator was used to put each injected oocyte in its 37°C setting. Results: The study showed that the age differences were insignificant (p=0.722), but significant variations emerged in sperm concentration before processing (p=1.030) and after (p=1.064). Sperm morphology differences were evident before processing (p=0.004) and after (p=0.002). No significant differences were noted in the number of Day 3 cleavage stage embryos. Conclusion: The study concluded that there is no significant difference between the two techniques regarding sperm washing efficiency.

Background: The third most common musculoskeletal symptom in orthopaedic clinical practice is a sore shoulder, which can cause significant morbidity. It has been reported that 7–27% of the general population has it, and 36–66% of overhead arm athletes have it. Pathophysiology includes functional, degenerative, and mechanical factors. Most shoulder pain is subacromial pain syndrome (SAPS), often known as ‘shoulder impingement syndrome’. Impingement hypothesis: shoulder joint structures mechanically clash. SAPS accounts for 36–48% of shoulder discomfort. Methods: This observational study was conducted in the Department of Orthopaedics, MKCG Medical College and Hospital, Berhampur, among Eastern Indian outpatients. The study included adult patients (ages 18–75) of both sexes who presented to MKCG Medical College and Hospital's OPD with shoulder pain from December 2020 to November 2022 and were diagnosed with Shoulder Impingement Syndrome (SIS). Thorough histories and clinical exams were done. The Department of Radiology, MKCG Medical College and Hospital, Berhampur, performed conventional shoulder MRIs on the selected participants. Results: Most cases and controls were Type-II (43.3%), followed by Type-I (28.3% and 30%, 29.2% of the total group). The study's least common acromial shape was type-IV, seen in 5% of cases and 10% of controls (7.5% of the sample). Fisher's exact test showed no significant connection between subacromial impingement and acromial shape (p=0.65). With a p-value of 0.045, cases had a significantly greater acromial width (8.12±2.16 mm) than controls (7.51±0.81 mm). Conclusion: Sub-acromial impingement was unrelated to acromion morphology. There was no correlation between acromial morphology and rotator cuff injuries.

Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

2 Case Reports of Gastric Ultrasound
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
