UAB researchers discover novel underlying mechanism involved in anxiety disorders, PTSD

University of Alabama at Birmingham neurobiologist Lynn Dobrunz, Ph.D., has discovered a novel mechanism for how stress-induced anxiety — the type of experience that can produce post-traumatic stress disorder, or PTSD — affects circuit function in the hippocampus, the area of the brain where aversive memories are formed.

Mathematical models can effectively predict and track malaria transmission

One of the most common infectious diseases in the world, malaria causes public health problems and depresses the economy of infected areas. When untreated or treated improperly, the disease can result in fatalities.

Tiny 'submarines' could help treat stomach diseases with acid-sensitive drugs

Tiny “submarines” that speed independently through the stomach, use gastric acid for fuel (while rapidly neutralizing it), and release their cargo precisely at the desired pH: Though it may sound like science fiction, this is a new method for treating stomach diseases with acid-sensitive drugs introduced by scientists in the journal Angewandte Chemie.

Tulane researchers discover cancer-causing role of protein thought to be tumor suppressor

Tulane University researchers have discovered that the protein PHLDB3, thought to be a potential tumor suppressor, actually allows cancer cells to thrive in pancreatic, prostate, colon, breast, lung, and other common cancers.

Researchers find brain abnormalities in Zika virus infected fetuses

In a study to be presented Friday, Jan. 27, in the oral concurrent session at 1:15 p.m. PST, at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, researchers with the Baylor College of Medicine Department of Obstetrics and Gynecology, Houston, Texas partnered with the Maternal-Fetal Unit, CEDIFETAL, Centro de Diagnostico de Ultrasonido e Imagenes, CEDIUL, Barranquilla, Columbia and the Unidad De Fertildad Y Genetica De Cartagena, Cartagena de Indias, Columbia, to create the study, Characterization of brain malformations and volume assessment in fetuses with Zika Virus infection using MRI.

Study identifies conserved role for Ovo protein in controlling germline development in mice and fruit flies

Germline cells are the only cells that develop into eggs or sperm, while somatic cells develop into the body. Progenitors of the germline, known as primordial germ cells (PGCs), differentiate into eggs or sperm after embryonic development.

Stroke-injured rat brain forms functioning connections with transplanted neurons, study shows

Today, a stroke usually leads to permanent disability - but in the future, the stroke-injured brain could be reparable by replacing dead cells with new, healthy neurons, using transplantation.

Researchers find new way to quantify olfactory sensory neurons using PET radiotracer

Olfactory health - how well we are able to smell - is a reliable marker of the health of the brain, but the "smell identification tests" commonly used in studies of olfactory health do not offer a complete picture of what is happening.

Vagus nerve stimulation may hold potential to reduce drug cravings, study shows

A new preclinical study led by a University of Texas at Dallas researcher shows that vagus nerve stimulation (VNS) therapy might have the potential to help people overcome drug addiction by helping them learn new behaviors to replace those associated with seeking drugs.

Researchers discover mutation hotspots that act like backseat drivers for breast cancer development

Researchers at the Wellcome Trust Sanger Institute have discovered 'hotspots' of mutations in breast cancer genomes, where mutations thought to be inactive 'passengers' in the genome have now been shown to possibly drive further cancerous changes.
