Aerobics good for young adults’ memory

A new research has revealed that aerobics may be beneficial for brain health and cognition, as certain hormones, which are increased during exercise, may help improve memory.

Hormones called growth factors are thought to mediate the relationship between exercise and brain health. The hippocampus, a region of the brain crucial for learning and memory, is thought to be uniquely affected by these hormones.

The growth factors brain-derived neurotrophic factor (BDNF), vascular endothelial growth factor (VEGF), and insulin-like growth factor-1 (IGF-1), have been implicated in the link between exercise and hippocampal function.

In this study, the researchers at Boston University School of Medicine recruited healthy young adults, in whom they measured blood hormone levels together with performance on a recognition memory task and aerobic fitness.

Newly discovered human peptide helps treat diabetes

A new research has found that a peptide produced by the human body could help in treating diabetes.

The recently discovered human peptide, called humanin, could lead to powerful new treatments for people living with diabetes as it helps in increasing the metabolism of glucose in beta cells, which in turn markedly increases insulin secretion.

Radhika Muzumdar, M.D., study author from the Departments of Pediatrics and Medicine at the Albert Einstein College of Medicine said that humanin could be a potential weapon to fight against this global problem which is expected to affect more than 500 million people in the next two decades.

The research also found that this human peptide may also benefit patients with other conditions like stroke, heart disease and Alzheimer’s.

Muzumdar added that this promising compound could have a dramatic effect on public health throughout the world.

Mixing energy drinks with alcohol hazardous to health

A new study has suggested that mixing energy drinks with alcohol is riskier than just drinking alcohol alone.

 Lead author of the study Megan Patrick from the University of Michigan Institute for Social Research said hey found that college students tended to drink more heavily and become more intoxicated on days they used both energy drinks and alcohol, compared to days they only used alcohol.

According to researchers, the public health implications include not only physical risks to individuals from blacking out and alcohol poisoning, for example, but also exposing the community to dangerous situations in which young adults may be “wide awake drunk” after a night of partying.

Patrick along with Jennifer Maggs of Penn State University analyzed data on 652 college students over a period of four semesters. During four two-week periods, the students answered questions every day about their consumption of energy drinks and alcohol, and about any negative consequences they experienced as a result—from having a hangover to getting into trouble.

“Our findings suggest that the use of energy drinks and alcohol together may lead to heavier drinking and more serious alcohol-related problems,” Patrick said.
The study was published in the current issue of the Journal of Adolescent Health.
