    After cardiac event, people who regularly sit for too long had higher risk of another event

    People who sit or remain sedentary for more than 14 hours a day, on average, may have a higher risk of a cardiovascular event or death in the year after treatment at a hospital for symptoms of a heart attack such as chest pain, according to new research published today in the American Heart Association’s peer-reviewed scientific journal Circulation: Cardiovascular Quality and Outcomes.

    Previous research from the study authors found that people who had experienced a heart attack were spending…

  • Don’t hit snooze on new research about waking up each morning

    Don’t hit snooze on new research about waking up each morning

    Sleep experts recommend against snoozing after a wake-up alarm, but a study led by researchers at Mass General Brigham shows the practice is common, with more than 50% of sleep sessions logged ending in a snooze alarm and users spending 11 minutes on average snoozing

    Even though using the snooze function on an alarm clock isn’t recommended by sleep experts, it’s a common practice, according to a new study led by researchers at Mass General Brigham. Using data from the sleep analysis app…

  • More donor hearts by extending the preservation time

    More donor hearts by extending the preservation time

    A new discovery by Mayo Clinic researchers could mean more donor hearts are available for heart transplant, giving more people a second chance at life. In findings published in Nature Cardiovascular Research, a team led by Mayo Clinic cardiac surgeon Paul Tang, M.D., Ph.D., identified a biological process that contributes to donor heart injury during cold storage. The researchers found that a drug already used to treat heart conditions can prevent this damage.

    Heart transplantation is the…

  • Early puberty increases risk of overweight later in life for girls

    Early puberty increases risk of overweight later in life for girls

    Girls who enter puberty early have a higher risk of developing overweight later in life — even if they were not overweight as children.

    This is shown by a new study from Aarhus University, which has analyzed height, weight, and puberty data from nearly 13,000 Danish children.

    “Overall, we found that children who entered puberty early had a higher BMI before, during, and after puberty,” explains postdoc Anne Gaml-Sørensen from the Department of Public Health.

    “However, we were surprised to…

  • A first blueprint of chemical transport pathways in human cells

    A first blueprint of chemical transport pathways in human cells

    An unprecedented international effort to decode how cells manage the transport of chemical substances has culminated in four groundbreaking studies published in Molecular Systems Biology. Led by Giulio Superti-Furga at CeMM, the Research Center for Molecular Medicine of the Austrian Academy of Sciences, and supported by an international consortium of academic and pharmaceutical partners under the European Union’s Innovative Medicines Initiative, this decade-long project provides the first…

  • Scientific breakthrough: We can now halve the price of costly cancer drug

    Scientific breakthrough: We can now halve the price of costly cancer drug

    The demand for the widely used cancer drug Taxol is increasing, but it’s difficult and expensive to produce because it hasn’t been possible to do it biosynthetically. Until now, that is. Researchers from the University of Copenhagen have cracked the last part of a code that science has struggled with for 30 years. The breakthrough could halve the price of the drug and make production far more sustainable.

    Taxol is one of the most commonly prescribed chemotherapy drugs for breast, ovarian,…

  • Family of parasite proteins presents new potential malaria treatment target

    Family of parasite proteins presents new potential malaria treatment target

    Researchers from the Francis Crick Institute and the Gulbenkian Institute for Molecular Medicine (GIMM) have shown that the evolution of a family of exported proteins in the malaria-causing parasite Plasmodium falciparum enabled it to infect humans.

    Targeting these proteins may hold promise for identifying new drugs that are less susceptible to resistance.

    Malaria infects over 200 million and kills over 500,000 people every year. It is caused by Plasmodium parasites infecting red blood cells…

  • Changes in the aging heart may lessen the risk of irregular heartbeats

    Changes in the aging heart may lessen the risk of irregular heartbeats

    Virginia Tech researchers at the Fralin Biomedical Research Institute at VTC have discovered that microscopic structural changes in the aging heart may reduce the risk of irregular heartbeats.

    Medically known as arrhythmias, irregular heartbeats become more common with age and can lead to health problems.

    But a new study in JACC Clinical Electrophysiology, a journal of the American College of Cardiology, revealed that a tiny gap between heart cells called the perinexus naturally narrows with…

  • New protein target for childhood medulloblastomas

    New protein target for childhood medulloblastomas

    Medulloblastomas are one of the most common childhood brain cancers.

    Particularly, Group-3 medulloblastomas are aggressive and incurable, contributing to childhood cancer deaths.

    Led by University of Michigan researchers, a study in Cancer Cellidentified a new target for Group-3 medulloblastomas.

    The results help identify new therapeutic avenues for treating these deadly tumors.

    Compared to normal cells, cancer cells use nutrients differently to build new molecules and generate energy.

    To…

  • Gut bacteria and acetate, a great combination for weight loss

    Gut bacteria and acetate, a great combination for weight loss

    Researchers led by Hiroshi Ohno at the RIKEN Center for Integrative Medical Sciences (IMS) in Japan have discovered a new way to reduce obesity. Their study shows that supplying the gut with extra acetate reduces fat and liver mass in both normal and obese mice, as long as bacteria of the Bacteroides species is also present in the gut. When both these conditions are met, gut bacteria can eliminate more sugars from the gut and promote the burning of fats for energy in the host. The findings…
