Infections in hospitalised individuals may arise from their own germs: Stu
Updated : 3 years, 1 month ago IST
Hospitals have strong cleanliness and sanitation measures in place to protect patients from microorganisms that rarely affect healthy people but can be deadly to vulnerable patients who are already hospitalised with serious illnesses.

Ethical ancient DNA research must involve descendant communities
Updated : 3 years, 1 month ago IST
The analysis of ancient DNA allows scientists to trace human evolution and make important discoveries about modern populations. The data revealed by ancient DNA sampling can be valuable, but the human remains that carry this ancient DNA are often those of the ancestors of modern Indigenous g

Overactive cell metabolism linked to biological ageing: Research
Updated : 3 years, 1 month ago IST
Why do cells, and by extension humans, age? The answer may have a lot to do with mitochondria, the organelles that supply cells with energy. Though that idea is not new, direct evidence in human cells had been lacking.

Enzyme 'atlas' helps researchers decipher cellular pathways
Updated : 3 years, 2 months ago IST
A new atlas maps more than 300 protein kinases found in human cells and identifies which types of protein substrates they target. The atlas could help scientists understand what happens when cells become cancerous or are treated with specific drugs.

Study: Hospitalised patients' infections may develop from their own bacter
Updated : 3 years, 2 months ago IST
Hospitals have strict hygiene and sanitation protocols to protect patients from bacteria that rarely sicken healthy people but can be deadly for vulnerable patients already hospitalized with serious illnesses. Nearly 100,000 people die every year in U.S. hospitals of infections they develop

Cardiac progenitor cells generate healthy tissue after heart attack
Updated : 3 years, 2 months ago IST
Following a heart attack, the human body is incapable of repairing lost tissue due to the heart's inability to generate new muscle. However, treatment with heart progenitor cells could result in the formation of functional heart cells at injured sites. This new therapeutic approach is introd

Stem cell population identified is vital for bone regeneration: Research
Updated : 3 years, 2 months ago IST
Researchers have identified a subpopulation of mesenchymal stem cells in the bone marrow that express the marker CD73. These cells have a higher potential for proliferation and differentiation, and play a significant role in bone healing, migrating to the site of a fracture and developing in

Research explains why women get more migraines
Updated : 3 years, 2 months ago IST
Research published today reveals a potential mechanism for migraine causation which could explain why women get more migraines than men. The study, in Frontiers in Molecular Biosciences, suggests that sex hormones affect cells around the trigeminal nerve and connected blood vessels in the he

Skin cancer cells use Alzheimer's protein to sabotage brain's immune defen
Updated : 3 years, 2 months ago IST
Amyloid beta, a protein known to build up in the brains of Alzheimer's patients, also helps skin cancer cells thrive when they spread to the brain, a new study finds.

Fat cell development is significantly influenced by circadian clocks
Updated : 3 years, 7 months ago IST
Washington [US], August 10 (ANI): Disruption of the circadian clocks that keep the body and its cells entrained to the 24-hour day-night cycle plays a critical role in weight gain, according to a pair of studies.

Study highlights link between mental disorders and gene readouts
Updated : 5 years, 1 month ago IST
Washington [US], February 9 (ANI): A research by the National Institute of Mental Health (NIMH) claims that the distinctions in the expression of gene transcripts that construct human body cells may hold the way to understand how mental issues with shared hereditary danger factors bring abou
