This document summarizes a study examining the role of HLA variability in tuberculosis. The study analyzed the HLA-DRB1 and HLA-DQB1 genes in 93 tuberculosis patients and 101 healthy controls in Venezuela. The frequencies of DRB1*12 and DQB1*0602 were significantly higher in patients, while DRB1*03 and DQB1*0306 were higher in controls. Certain HLA-DQB1 allele combinations encoding or not encoding aspartate at position 57 in the beta chain were only found in patients. The DRB1*13-DQB1*06 haplotype was also more common in controls than patients. The results suggest HLA polymorphisms influence the occurrence of tuberculosis in these patients.

1) A study found that about half of patients treated for HIV early in infection failed to develop antibodies detectable by standard HIV tests or developed antibodies that later disappeared.
2) Current HIV diagnostic tests are designed based on the natural progression of HIV infection without treatment, but early treatment interrupts antibody development.
3) With increased emphasis on rapid treatment even in acute HIV, the limitations of diagnostic tests need to be addressed to accurately diagnose HIV in people on early treatment.
The Global Virome Project is a 10-year global effort to identify and characterize naturally occurring viruses with pandemic potential. It aims to build a comprehensive database of the estimated 1.6 million viral species circulating in mammals and waterfowl. This will allow researchers to develop broad-spectrum countermeasures against future zoonotic viruses and identify high-risk viruses to prevent spillover. The project will sample viruses in 108 sites across 63 countries over 10 years, prioritizing countries and species based on viral discovery rates and zoonotic risk prediction models. The goal is to capture over 85% of the global mammalian virome to transform virology and pandemic preparedness.
This document summarizes key information about Norovirus, including its structure, transmission, diagnosis, and epidemiology. It notes that Norovirus is the leading cause of foodborne illness worldwide, with transmission primarily through the fecal-oral route. Diagnosis involves detecting viral RNA or antigens, though culturing the virus in human intestinal cells was recently developed. Norovirus causes an estimated 267 million infections annually and is responsible for over half of all cases of gastroenteritis globally.
This research article characterized the genetic diversity of Plasmodium vivax and P. falciparum populations from pregnant women in four malaria-endemic countries. Between 2008-2011, nearly 2000 pregnant women were recruited from Brazil, Colombia, India, and Papua New Guinea and followed until delivery, collecting blood samples. Seven P. vivax microsatellite markers were used to genotype 229 P. vivax isolates. P. vivax populations showed moderate to high genetic differentiation between countries and higher diversity than P. falciparum populations from the same areas. Diversity of P. vivax was very high in some settings compared to transmission levels, suggesting stable demographic histories.

Neonatal sepsis is the cause of substantial morbidity and mortality. Precise estimates of neonatal sepsis burden vary by
setting. Differing estimates of disease burden have been reported from high-income countries compared with reports
from low-income and middle-income countries. The clinical manifestations range from subclinical infection to severe
manifestations of focal or systemic disease. The source of the pathogen might be attributed to an in-utero infection,
acquisition from maternal flora, or postnatal acquisition from the hospital or community. The timing of exposure,
inoculum size, immune status of the infant, and virulence of the causative agent influence the clinical expression of
neonatal sepsis. Immunological immaturity of the neonate might result in an impaired response to infectious agents.
This is especially evident in premature infants whose prolonged stays in hospital and need for invasive procedures
place them at increased risk for hospital-acquired infections. Clinically, there is often little difference between sepsis
that is caused by an identified pathogen and sepsis that is caused by an unknown pathogen. Culture-independent
diagnostics, the use of sepsis prediction scores, judicious antimicrobial use, and the development of preventive
measures including maternal vaccines are ongoing efforts designed to reduce the burden of neonatal sepsis
This document provides an overview of Crimean-Congo hemorrhagic fever (CCHF). It discusses that CCHF is a tick-borne viral disease caused by the CCHF virus, which causes severe hemorrhagic fever outbreaks with a fatality rate of 10-40%. The virus is found across Africa, the Middle East, Asia, and parts of Europe. The first cases of CCHF in India were reported in 2011 in Gujarat. While there is no approved treatment, supportive care and the antiviral ribavirin may increase survival rates when administered early.
Combating Drug Resistance in The Intensive Care Unit (ICU)Apollo Hospitals
Drug resistance of microbes has become a major challenge in treating ICU patients successfully. There are many factors that contribute to the development of drug resistance, including irrational antibiotic use, lack of antibiotic stewardship programs, and poor infection control practices. Implementing strict antibiotic policies, having responsive microbiology departments, and educating healthcare providers on following clinical guidelines are important first steps to prevent drug resistance. It is also essential to monitor antibiotic use, tailor therapies based on culture results, and withdraw antibiotics appropriately once infections have resolved. A multifaceted approach involving hospitals, healthcare workers, and communities is needed to curb the growing issue of antimicrobial resistance.
This document discusses infectious diseases and healthcare-associated infections. It begins with an overview of hospital epidemiology and the roles of epidemiologists in identifying risks of infection and developing strategies to minimize those risks. Common sites of healthcare-associated infections are the urinary tract, respiratory tract, bloodstream, surgical wounds, and gastrointestinal tract. Factors that can promote healthcare-associated infections include prolonged use of medical devices, extremes of age, surgery and other procedures, immune status, understaffing, and poor infection control practices. The document then discusses measures for quantifying disease frequency like prevalence, incidence and case definitions.
FOURNIER’S GANGRENE: REVIEW OF 57 CASES IN TERTIARY INSTITUTIONAnil Haripriya
Fournier’s gangrene which is a rapidly progressive, fulminant polymicrobial synergistic infection of the perineum and genitals is now changing its pattern. Both genders can be affected and the mortality is still high (around10%). The clinical presentation in many patients in early stage may not be prominent. Thus rapid and accurate diagnosis is must for prompt treatment. Extensive surgical debridement and broad spectrum intravenous antibiotic remains the mainstay of treatment in order to reduce the morbidity and mortality.
Asymptomatic Trasmission, the Achilles'Heel of Current Strategies to Control ...Valentina Corona
The editorial discusses an outbreak of COVID-19 at a skilled nursing facility in Washington where asymptomatic transmission played a major role in spreading the virus. Over half of the residents who tested positive were asymptomatic at the time of testing, and live virus was detected in samples from presymptomatic residents days before they developed symptoms. Current strategies relying on symptom screening alone are inadequate for controlling transmission. The authors argue for expanded testing of asymptomatic individuals in high-risk settings like nursing homes to allow for proper isolation and prevent further outbreaks.
This document discusses infections in pregnancy, including TORCH infections (toxoplasmosis, other [syphilis], rubella, cytomegalovirus, and herpes simplex virus), as well as HIV in pregnancy. It describes how pregnancy predisposes women to certain infections due to immunocompromise. It provides details on screening, diagnosis, treatment and management of various infections that can affect the mother and fetus, including toxoplasmosis, rubella, cytomegalovirus, syphilis, herpes, and HIV. It also discusses pre-pregnancy, antenatal, intrapartum and postpartum care recommendations for HIV-positive women.
Meningitis is an inflammation of the protective membranes covering the brain and spinal cord. It can be caused by bacteria, viruses, or other sources. The presentation of symptoms can be similar for viral and bacterial meningitis, including fever, headache, and stiff neck. However, bacterial meningitis requires urgent treatment with antibiotics to prevent serious complications. Public health follow-up includes identifying close contacts of bacterial meningitis cases who may require preventative antibiotics or vaccination. Health departments investigate suspected meningitis cases and outbreaks to control spread.
- Early-onset neonatal sepsis remains a common cause of morbidity and mortality in preterm infants, despite improved obstetric management and antibiotic use.
- The signs and symptoms of neonatal sepsis are nonspecific, and diagnostic tests have poor predictive accuracy, so clinicians often treat infants empirically even when cultures are negative.
- The optimal treatment for suspected early-onset sepsis is broad-spectrum antibiotics like ampicillin and an aminoglycoside, though therapy should be narrowed once a pathogen is identified or discontinued by 48 hours if sepsis is deemed unlikely.
The document discusses concerns about the MMR vaccine and a potential link to autism. It provides details on vaccine ingredients including fetal bovine serum and human fetal cells. It summarizes testimony from a Congressional hearing linking vaccines to autism, including findings of measles virus in the gut and autoimmune responses post-vaccination. The document also discusses the history of measles and implications of vaccination and waning immunity over time.
The document discusses the origins and nature of the swine flu virus, which first emerged in Mexico in 2009. It is a respiratory disease in pigs caused by influenza A that can spread from human to human. The virus contains genetic material from multiple animal sources and many people lacked immunity to it, allowing it to cause a pandemic. Health authorities were closely monitoring the virus as it spread beyond Mexico to other countries. The document provides statistics on early cases and discusses strategies, symptoms, treatments, and precautions to control the spread of the virus.
Nosocomial Infections in Pediatric Intensive Care Unitijtsrd
Hospital acquired infection is one of the ignored causes that burden the developing country like India economically. The present prospective study was carried out in the Pediatric Intensive Care Unit (PICU) of a tertiary care teaching hospital in Mumbai. As intensive care units pose patients to higher risk of infection, they need more attention in view of reducing hospital acquired infections. This study was undertaken to determine the incidence rate, risk factors and organisms responsible for nosocomial infections along with antimicrobial sensitivity patterns of the pathogens. Among all the positive isolates two isolates were found to be multi drug resistant. The infection pattern was analyzed based on the different criteria viz. age of the patient, stay in ICU in terms of number of days and gender of the patient, to understand their roles in incidence of infection. The study intends to throw light upon the increasing incidences of nosocomial infections in hospitals and increase awareness among society to follow simple precautionary measures to avoid the loss.

When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
ANAMOLOUS SECONDARY GROWTH IN DICOT ROOTS.pptxRASHMI M G
Abnormal or anomalous secondary growth in plants. It defines secondary growth as an increase in plant girth due to vascular cambium or cork cambium. Anomalous secondary growth does not follow the normal pattern of a single vascular cambium producing xylem internally and phloem externally.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.
BREEDING METHODS FOR DISEASE RESISTANCE.pptxRASHMI M G
Plant breeding for disease resistance is a strategy to reduce crop losses caused by disease. Plants have an innate immune system that allows them to recognize pathogens and provide resistance. However, breeding for long-lasting resistance often involves combining multiple resistance genes

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...AbdullaAlAsif1
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
Nucleophilic Addition of carbonyl compounds.pptxSSR02
Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general.
Carbonyls undergo addition reactions with a large range of nucleophiles.
Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen.
Electronic effects (inductive effects, electron donation) have a large impact on reactivity.
Large groups adjacent to the carbonyl will slow the rate of reaction.
Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.

* Being able to characterize viral populations rapidly and
accurately is important for understanding pathogenesis,
interplay between viruses and humoral responses, and the
evolution of drug resistance
* Both HIV-1 and HCV exist as viral quasispecies in a host, i.e.
many distinct viral strains are circulating at any given moment in
time
* NGS has the potential to directly sequence many such strains
* Using multiplexing (multiple samples/run), high throughput
can be achieved
