Strange hyperactivation in brain can be early sign of Alzheimer’s.

A research led by psychology and neuroscience professor of the University of Montreal highlights that abnormally hyperactive areas in the brain may help better predict the onset of Alzheimer's disease.In the study, the team led by Universite de Montreal psychology professor Sylvie Belleville, found hyperactivation in certain brain areas in people not yet diagnosed with Alzheimer's but who were worried about their memory and who exhibited risk factors for the disease.The findings which were published...

Researchers find how cancer can be killed by body’s own immune system.

A new way to help the body's immune system get past that deception and destroy cancer, has been found by a University of Missouri researcher."Normally, your body's immune cells are constantly on patrol to identify and destroy foreign entities in the body," said Yves Chabu, an assistant professor in the Division of Biological Sciences."Normal cells put up a 'don't-eat-me' molecular flag that is recognized by immune cells, thereby preventing the destruction of normal tissues. But some cancers have...

Rapid blood test can now identify patients at highest risk of severe Covid-19.

Scientists have developed a rapid blood test that can predict within a day of hospitalization which patients with Covid-19 are at the highest risk of severe complications or death, an advance that may help identify those who may best benefit from specific investigational treatments.The test, described in the journal JCI Insight, measures levels of mitochondrial DNA - a unique type of genetic material that normally resides inside the energy factories of cells.According to the researchers from the Washington...

Coronavirus: Critical care staff suffer trauma, severe anxiety due to Covid-19.

Nearly half of staff working in intensive care units (ICU) in England in the COVID-19 pandemic have severe anxiety, depression or post-traumatic stress disorder, with some reporting feeling they'd be better off dead, according to a study published on Wednesday. Many ICU nurses and doctors meet the clinical threshold for PTSD, anxiety or problem drinking, and symptoms are so severe that some reported contemplating self-harm or suicide.Such acutely poor mental health among ICU staff caring for critically...

Study suggests Pfizer vaccine works against virus variant.

New research suggests Pfizer’s Covid-19 vaccine can protect against a mutation found in the two more-contagious variants of the coronavirus that have erupted in Britain and South Africa.The study was preliminary and did not look at the two other major vaccines being used in the West — Moderna’s and AstraZeneca’s. But it was reassuring, given questions of whether the virus could mutate to defeat the shots on which the world has pinned its hopes.“There’s no reason to think the vaccines...

Study finds protein critical to T cell metabolism, anti-tumour immune response.

Researchers at The University of Texas MD Anderson Cancer Center have discovered that a protein called NF-kappa B-inducing kinase (NIK) is essential for the shift in metabolic activity that occurs with T cell activation, making it a critical factor in regulating the anti-tumour immune response.The preclinical research, published today in Nature Immunology, suggests that elevating NIK activity in T cells may be a promising strategy to enhance the effectiveness of immunotherapy, including adoptive...

Vaccines 100% safe, rumours of impotency is ‘absolute rubbish’: Somani.

Drugs Controller General of India (DCGI) VG Somani on Sunday assured people about the safety of the two Covid-19 vaccines by Bharat Biotech and Oxford-AstraZeneca as he gave the final approval for the shots. Somani made the formal announcement approving Serum Institute of India-manufactured Oxford-AstraZeneca vaccine and indigenously developed Covaxin of Bharat Biotech for restricted emergency use in the country.“After adequate examination, CDSCO has decided to accept the recommendations of the Expert...

Study reveals single gene ‘invented’ hemoglobin several times.

Thanks to the marine worm Platynereis dumerilii, an animal whose genes have evolved very slowly, a team of scientists have shown that while hemoglobin appeared independently in several species, it actually descends from a single gene transmitted to all by their last common ancestor.The findings of the study by scientists from CNRS, Universite de Paris and Sorbonne Universite, in association with others at the University of Saint Petersburg and the University of Rio de Janeiro, were published in the journal...

India’s first indigenous pneumonia vaccine by SII launched.

The first indigenous vaccine against pneumonia, developed by the Serum Institute of India (SII), was launched by Union health minister Harsh Vardhan on Monday. The vaccine would be sold under the name ‘Pneumosil’ and would be available either as a single dose in a vial and pre-filled syringe or as multidose in vials at affordable prices, the Union ministry of health and family welfare (MoHFW) said in a statement.The pneumococcal conjugate vaccine (PCV) would be used to treat pneumonia in children...

Studies find having Covid-19 may protect against reinfection.

Two new studies give encouraging evidence that having Covid-19 may offer some protection against future infections. Researchers found that people who made antibodies to the coronavirus were much less likely to test positive again for up to six months and maybe longer.The results bode well for vaccines, which provoke the immune system to make antibodies — substances that attach to a virus and help it be eliminated.Researchers found that people with antibodies from natural infections were “at much...
