Failure of specialised beta cells may cause diabetes: Study

London: The failure of a handful of beta cell “hubs” in the pancreas are the likely reason for developing diabetes, rather than the behaviour of all cells, says a study. Type 2 diabetes occurs when the pancreas fail to produce enough insulin to function properly, meaning that glucose stays in the blood rather than being

New forms of HIV can jump from animals to humans

New York: While the HIV epidemic continues to threaten health and well-being of a large section of the world’s population, scientists have warned that new forms of the virus jumping from animals to humans cannot be ruled out. The suggestion stems from a study in which the scientists discovered the first in vivo evidence that

Can antibiotics slow Alzheimer’s progression?

New York: Researchers, including one of Indian-origin, have found that long-term antibiotic treatment in mice decreases levels of amyloid plaques, a hallmark of Alzheimer’s disease. The study, published in the journal Scientific Reports, also showed significant changes in the gut microbiome after antibiotic treatment, suggesting the composition and diversity of bacteria in the gut play

Women with ADHD more likely to have suicidal thoughts

Toronto: Women with attention-deficit/hyperactivity disorder (ADHD) have more than four times the odds of suicidal thoughts and generalised anxiety disorders, says a study. “Many people think of ADHD as primarily a boys’ disorder which has little relevance for girls and women. Our findings suggest, to the contrary, that a large portion of women with ADHD

Don’t blame genes for all diseases that run in families

London: A family history of disease may be as much the result of shared lifestyle and surroundings as inherited genes, a study says. Factors that are common to the family environment – such as shared living space and common eating habits – can make a major contribution to a person’s risk of disease, the study

Protein that can boost growth of damaged muscle tissue

New York: Researchers have found that a protein that plays a key role in the lives of stem cells can bolster the growth of damaged muscle tissue, a step that could potentially contribute to treatments for muscle degeneration caused by old age and diseases such as muscular dystrophy. “We provide here a proof-of-principle study that

Brain plays key role in gauging errors

New York: The key element in our decision-making that serves to both gauging errors and revising our approach is confidence, suggested a new study. The study, published in the journal Proceedings of the National Academy of Sciences, offers insights into the hierarchical nature of how we make choices over extended periods of time, ranging from

HIV therapy cuts mother-to-child transmission during breastfeeding

New York: For mothers who are infected with human immunodeficiency virus (HIV) but their immune system is in good health, taking a three-drug antiretroviral regimen during breastfeeding period can essentially eliminate HIV transmission by breast milk to their infants, finds a study. The findings showed that both three-drug maternal antiretroviral therapy and daily infant nevirapine

Nasal irrigation good for patients with chronic sinus: Study

London: Advising patient with chronic sinus congestion to use nasal irrigation — a popular nonpharmacologic treatment — improved their symptoms, but steam inhalation did not, results of a new trial show. “We have found that even a very brief intervention of a video showing patients how to use saline nasal irrigation can improve symptoms, help

Worry not, as feeding cinnamons, a delicious addition to toast, coffee and breakfast rolls might help improve learning ability, says a study led by an Indian-origin researcher. The findings showed that the poor learning mice had improved memory and learning at a

Immune system can affect social behaviour

New York: A malfunctioning immune system may be responsible for social deficits in neurological diseases such as autism-spectrum disorders and schizophrenia, suggests new research. “Our findings contribute to a deeper understanding of social dysfunction in neurological disorders, such as autism and schizophrenia, and may open new avenues for therapeutic approaches,” said Vladimir Litvak, Assistant Professor

Smoking rates high in emergency patients

Canberra: A new study has found that patients in the emergency department have significantly higher rates of smoking than the general population. A study undertaken using a sample of almost 340 emergency department patients in Melbourne’s St. Read: Smoking weed and tobacco in joints cuts motivation to quit Vincent’s Hospital and the Austin Hospital, reported a

Why young Americans are having babies before marriage

New York: Rising income inequality, and the resulting scarcity of certain types of jobs, is a key reason a large number of millennials in the US are having babies before getting married, a study says. The researchers traced how the income gap, a large-scale societal trend, was affecting individual personal choices about starting a family.

Protein that may ‘shock and kill’ HIV virus identified

New York: Researchers have identified a protein that can potently force the latent human immunodeficiency virus (HIV) viruses out of hiding and poison them on their way out, leading to potential treatments for the deadly disease. The findings showed that galectin-9 — a human sugar-binding protein — reactivates latent HIV viruses and renders these infected

Drug-use may damage ability to choose right from wrong

New York: Regular drug users can have difficulty choosing between right and wrong, perhaps because the specific parts of their brains used for moral processing and evaluating emotions are damaged by their prolonged drug habits, says a study. There is strong link between drug use and criminal behaviour, but it is not known whether the

Cancer risk may rise before and after diabetes diagnosis: Study

Toronto: Individuals with Type 2 diabetes may be at an increased risk of developing cancer before and immediately after their diagnosis, says a study. The findings showed that the highest risk appears shortly after a diabetes diagnosis. Cancer incidence was also significantly higher in persons with diabetes within the first three months after diagnosis, but

‘Superbug’ gene detected in second US patient

Washington: Bacteria carrying the MCR-1 “superbug” gene was found in a second US patient, researchers said on Monday. The gene was detected in an isolate of Escherichia coli that was originally recovered in 2015 from a patient in New York, according to the research published in Antimicrobial Agents and Chemotherapy, a journal of the American

AIDS no longer public health issue in Aus: Experts

Melbourne: Australia’s top scientists havedeclared that AIDS is no longer a public health issue in the country as it has joined the ranks of the few nations which have successfully beaten the deadly epidemic. Acquired Immune Deficiency Syndrome (AIDS) cases in Australia have dropped since anti-retroviral medication came in the mid-1990s, which stops the Human
