Biological pathways in PTSD revealed: Study

Up to 20% of the population exposed to a horror of a war, trauma or abuse may go on to develop post-traumatic stress disorder. PTSD, as it is better known, is a debilitating psychiatric disorder marked by flashbacks and nightmares. Till date the biological basis for PTSD was unclear. But a new study offers clues about why some people rebound from horrific events while others relive them, and may lead to predictive tests and even treatments.

Dual lab tests accurately predict vein graft blood clots in patients during CABG

A team of heart experts at Johns Hopkins has found that dual lab tests of blood clotting factors accurately predict the patients whose blood vessels, in particular veins implanted to restore blood flow to the heart during coronary artery bypass grafting, are more likely to fail or become clogged within six months.

Knocking out genes completely and exclusively in Natural Killer cells

Our immune systems contain three fundamentally different types of cell: B-cells, T-cells and the mysteriously named Natural Killer cells (NK cells), which are known to be involved in killing tumour cells and other infected cells. Experiments to investigate the function of NK cells have proven difficult to interpret because the interactions between the various components of the immune system make it almost impossible to isolate effects of individual cell types.

Tifacogin administration shows no treatment benefit in patients with severe CAP

Use of the blood clot-inhibiting medication tifacogin does not appear to improve outcomes of patients with severe community-acquired pneumonia, according to a study conducted by researchers from North and South America, Europe, Asia and Africa. The drug had shown some potential benefit in the sCAP subgroup of an earlier trial involving sepsis patients.

New study provides insight into brain activity of depressed women responding to crying infants

Mothers who are depressed respond differently to their crying babies than do non-depressed moms. In fact, their reaction, according to brain scans at the University of Oregon, is much more muted than the robust brain activity in non-depressed moms.

Higher intake of vitamin D may reduce breast cancer risk

Researchers at the University of California, San Diego School of Medicine and Creighton University School of Medicine in Omaha have reported that markedly higher intake of vitamin D is needed to reach blood levels that can prevent or markedly cut the incidence of breast cancer and several other major diseases than had been originally thought. The findings are published February 21 in the journal Anticancer Research.

Mutated cancer pathway studies identify therapeutic targets for congenital heart disease

Cross-disciplinary teams of scientists studying genetic pathways that are mutated in many forms of cancer, but which also cause certain forms of congenital heart disease - including hypertrophic cardiomyopathy, a thickening of the heart muscle that is the leading cause of sudden death in children and young adults -, have introduced these mutations into mice and successfully treated HCM in the lab.
