Scientists reverse aging-associated skin wrinkles and hair loss in a mouse model

Fri, 07/20/2018 - 11:28am
Researchers have reversed wrinkled skin and hair loss, hallmarks of aging, in a mouse model. When a mutation leading to mitochondrial dysfunction is induced, the mouse develops wrinkled skin and extensive, visible hair loss in a matter of weeks. When the mitochondrial function is restored by turning off the gene responsible for mitochondrial dysfunction, the mouse returns to smooth skin and thick fur, indistinguishable from a healthy mouse of the same age.

Effect of genetic factors on nutrition: The genes are not to blame

Fri, 07/20/2018 - 9:25am
Individualized dietary recommendations based on genetic information are currently a popular trend. A team has systematically analyzed scientific articles and reached the following conclusion: There is no clear evidence for the effect of genetic factors on the consumption of total calories, carbohydrates, and fat. According to the current state of knowledge, the expedience of gene-based dietary recommendations has yet to be proven.

Diabetes raises risk of cancer, with women at even greater likelihood, a major new study has found

Thu, 07/19/2018 - 7:56pm
A global review involving almost 20 million people has shown that having diabetes significantly raises the risk of developing cancer, and for women the risk is even higher. Researchers also found diabetes (type 1 and type 2) conferred an additional risk for women, compared to men, for leukaemia and cancers of the stomach, mouth and kidney, but less risk for liver cancer.

Response to HIV/AIDS epidemic at risk of 'dangerous complacency' as urgent change in approach is needed

Thu, 07/19/2018 - 7:56pm
HIV rates persist in high risk, marginalized populations and the Commission authors warn that a resurgence of the epidemic is likely as the largest generation of young people age into adolescence and adulthood. * Stalling of HIV funding in recent years endangers HIV control efforts. Historic 'exceptionalism' of HIV treatment and care may no longer be sustainable; services will likely need to be part of wider health care supporting related diseases and conditions.
