Creating a mutation that inhibits how the bacterial pathogen Neisseria gonorrhoeae causes gonorrhea, a common sexually transmitted infection, could offer a new way to prevent and treat the disease, according to researchers in the Institute for Biomedical Sciences at Georgia State University.

FDA promotes children clinical trials for drugs, biological products and medical devices. FDA perspective on the ethical considerations for including and protecting children in clinical trials.

And for that purpose, the draft guidance for children who participate in clinical trials is released which intends to assist industry, sponsors and institutional review boards (IRBs).

People who wear reusable contact lenses are nearly four times as likely as those wearing daily disposables to develop a rare sight-threatening eye infection, finds a study led by UCL and Moorfields researchers.

Two new UC Davis Health studies explored how differences in skin composition may lead to dermatological conditions, such as psoriasis and atopic dermatitis.

“Skin does not have a uniform composition throughout the body,” said Emanual Maverakis, professor of dermatology, molecular medical microbiology at UC Davis and senior author on both studies. “Different skin characteristics at different body sites may affect the skin’s susceptibility to certain diseases.”

A new mechanism that slows down and may even prevent the natural ageing of immune cells – one of the nine hallmarks of ageing – has been identified by an international team led by UCL scientists.

Published in Nature Cell Biology, researchers say the discovery in-vitro (cells) and validated in mice was ‘unexpected’ and believe harnessing the mechanism could extend the life of the immune system, allowing people to live healthier and longer, and would also have clinical utility for diseases such as cancer and dementia.

it may be the most baffling quirk of COVID: What manifests as minor, flu-like symptoms in some individuals spirals into severe disease, disability, or even death in others. A new paper published in Nature may explain the genetic underpinnings of this dichotomy.

Lower immunity and recurring infections are common in type 1 and type 2 diabetes. Researchers at Karolinska Institutet now show that the immune system of people with diabetes has lower levels of the antimicrobial peptide psoriasin, which compromises the urinary bladder’s cell barrier, increasing the risk of urinary tract infection. The study is published in Nature Communications.

Because of their highly active metabolism, many tumors are susceptible to a special type of cell death, ferroptosis. Nevertheless, cancer cells often manage to escape this fate. Scientists at the German Cancer Research Center have now discovered a new mechanism by which normal as well as cancer cells protect themselves against ferroptosis. Knowledge of these molecular connections could provide new starting points for the treatment of tumors.

Neuromorphic computing system technology mimicking the human brain has emerged and overcome the limitation of excessive power consumption regarding the existing von Neumann computing method. A high-performance, analog artificial synapse device, capable of expressing various synapse connection strengths, is required to implement a semiconductor device that uses a brain information transmission method. This method uses signals transmitted between neurons when a neuron generates a spike signal.
