Cell-killing Proteins Suppress Listeria without Killing Cells

RIPK3, a key mediator of necroptosis, has been implicated in the host defense against viral infection primary in immune cells. However, gene expression analysis revealed that RIPK3 is abundantly expressed not only in immune organs; but also in the gastrointestinal tract, particularly in the small intestine. We found that orally inoculated Listeria monocytogenes; a bacterial…

Immune System Fails Despite HIV Suppression

Antiretroviral therapy (ART) is the standard of care for patients with HIV. For most patients, ART-mediate suppression of HIV replication is accompanied by reconstitution of CD4+ T cells; however, in some cases, the CD4+ T cell population is not fully restored, and these immunological nonresponders (INRs) have increased mortality. In this episode, Irini Sereti, Andrea Lisco, and…

Major And Minor Collagens From Hyaline Cartilage of Hoki

Collagens and proteoglycans are the main proteins in the extra cellular matrix of cartilage; together with water, they give cartilage its strength and elastic properties. In human cartilage, the majority of the collagen framework is up of type II collagen; accompanied by lesser amounts of minor collagens (1%–6% of total collagen), such as type IX…

The Hepatitis B Virus Establishes Persistent Infection

New research sheds light on how a hepatitis B viral protein stimulates the expansion of immune cells; that impair antiviral responses, according to a study published; in the open-access journal PLOS Pathogens by Haitao Guo of the Indiana University School of Medicine, Bin Wang and Jiming Zhang of Fudan University, and colleagues. The findings potentially…

Salmonella

Infection Biology: Gut Microbe Helps Thwart Salmonella

Salmonella enterica is the name of a group of rod-shaped bacteria that can cause gastroenteritis in humans and other animals. Salmonella infections can have serious consequences for certain high-risk groups; such as babies, young children; the elderly and individuals whose immune systems are functionally; compromised. Most people with a normal complement of gut microflora (microbiota)…

Employee Wellness Programs Provide Little Health Benefits

Although employees did demonstrate improvement in health behaviors such as weight management and exercising regularly; the wellness programs did not cut costs, reduce absenteeism rates or improve health outcomes. The findings, which were recently published in JAMA; come amidst an expansion in the uptake of wellness programs. The programs now represent an $8 billion industry in…

Curb Drug Abuse with Focus on Public Health

Policy-making requires a clear understanding of whether; how and to what degree imprisonment for drug offences; affects the nature and extent of the drug problem. An effective response to drug abuse requires law enforcement to curtail trafficking; treatment to reduce dependency; and alternative sentencing for non-violent drug offenders. GRAPPLING with drug abuse, countries are realising;…

MRI Method Developed to Measure Brain Function

The speed of the human brain is remarkable in a fraction of a second; neurons are activated, propagating thoughts and reactions to stimuli. But the speed at which we can noninvasively follow brain function using an MRI is not as impressive. Functional MRI (fMRI); which measures changes in blood oxygen levels, has revolutionized the field…

Sleep apnea

Developing Oral Appliance To Help Sufferers Of Sleep

Researchers measured a novel treatment for sleep apnea developed at Hiroshima University Hospital with positive results. By measuring patients lying down flat, the researchers stimulated sleep conditions and measured the patient’s airways using 3D imaging. The study confirmed that the treatment is effective at opening the airways and warrants further collaboration; between dentists and doctors…
