Study: Childhood abuse linked to greater risk of endometriosis
A study of more than 60,000 women has found that sexual and physical abuse in childhood and adolescence is associated with a greater risk of laparoscopically-confirmed endometriosis diagnosed during adulthood. The study — the largest of its kind — found that women reporting severe-chronic abuse of multiple types had a 79 percent higher risk of laparoscopically-confirmed endometriosis.

The early PCs are retained within the reactive lymphoid organ where their localization and homeostasis rely on extrinsic factors, presumably produced by local niche cells. While myeloid cells have been proposed to form those niches, the contribution by…

Induction of oligoclonal CD8 T cell responses against pulmonary metastatic cancer by a phospholipid-conjugated TLR7 agonist [Medical Sciences]
Recent advances in cancer immunotherapy have improved patient survival. However, only a minority of patients with pulmonary metastatic disease respond to treatment with checkpoint inhibitors.

Rsd balances (p)ppGpp level by stimulating the hydrolase activity of SpoT during carbon source downshift in Escherichia coli [Microbiology]
Bacteria respond to nutritional stresses by changing the cellular concentration of the alarmone (p)ppGpp. This control mechanism, called the stringent response, depends on two enzymes, the (p)ppGpp synthetase RelA and the bifunctional (p)ppGpp synthetase/hydrolase SpoT in Escherichia coli and related bacteria. Because SpoT is the only enzyme responsible for (p)ppGpp…

Disruption of divisome assembly rescued by FtsN-FtsA interaction in Escherichia coli [Microbiology]
Cell division requires the assembly of a protein complex called the divisome.

FtsEX arrives as the…

Anti-obesity drug derived from chili peppers shows promise in animal trials
A novel drug based on capsaicin, the compound that gives chili peppers their spicy burn, caused long term weight loss and improved metabolic health in mice eating a high fat diet, in new studies from the University of Wyoming School of Pharmacy. The drug, Metabocin, was designed to slowly release capsaicin throughout the day so it can exert its anti-obesity effect without producing inflammation or

Heritable genome editing: Action needed to secure responsible way forward
An independent inquiry has concluded that editing the DNA of a human embryo, sperm, or egg to influence the characteristics of a future person ('heritable genome editing') could be morally permissible. If that is to happen, a number of measures would need to be put in place first to ensure that genome editing proceeds in ways that are ethically acceptable.

Lack of this stuff in fat may cause obesity and diabetes

The findings also show that the absence of cardiolipin in fat cells is causally linked to pre-diabetes and type 2 diabetes. “Switching off production of cardiolipin in mice leads to insulin resistance, which is the cornerstone of diabetes.” Large amounts of cardiolipin produced in the fat
