Researchers develop cell culture model that could help develop early treatment strategies for AMD

An international team from the University of Alabama at Birmingham and University College London and Queens University Belfast in the United Kingdom developed a cell culture model that could help to develop earlier treatment strategies for age-related macular degeneration, the third most prevalent cause of vision loss worldwide.

Precision-medicine approach could improve accuracy of PSA-based prostate cancer screening tests

A new study led by researchers at UC San Francisco and Kaiser Permanente has identified genetic predictors of normal prostate-specific antigen (PSA) levels in healthy men, which could be used to improve the accuracy of PSA-based prostate cancer screening tests.

Vasculature in mini-brains expands research potential

Scientists have recently made a wondrous variety of mini-brains -- 3-D cultures of neural cells that model basic properties of living brains -- but a new finding could add to the field's growing excitement in an entirely new "vein": Brown University's mini-brains now grow blood vessels, too.

Study paves way for therapies against myeloid-derived suppressor cells that collude with cancer

Some cells excite the immune system. Others soothe it. Myeloid-derived suppressor cells (MDSCs) are one type of soothing cell, and previous work shows that cancer may specifically boost production of MDSCs as a way to tamp down immune response against tumors. At least that's how it works in mice.

Changes in astronaut's gut microbes linked to spaceflight

Northwestern University researchers studying the gut bacteria of Scott and Mark Kelly, NASA astronauts and identical twin brothers, as part of a unique human study have found that changes to certain gut "bugs" occur in space.

UW-Madison scientists discover bone marrow proteins that regulate bone-building cells

The prospect of regenerating bone lost to cancer or trauma is a step closer to the clinic as University of Wisconsin-Madison scientists have identified two proteins found in bone marrow as key regulators of the master cells responsible for making new bone.

Increased growth factor protects retinal blood vessels in animal models with diabetes

Researchers from the Schepens Eye Research Institute of Massachusetts Eye and Ear have shown that a slight increase in transforming growth factor beta (TGF-β), which is present in preclinical animal models with diabetic eye disease, protects retinal blood vessels from damage that commonly occurs in the early stages of the disease.

Virulence of bacterial infections dependent on presence of cytotoxins, study reports

Beginning in the mid-1980s, an epidemic of severe invasive infections caused by Streptococcus pyogenes (S. pyogenes), also known as group A streptococcus (GAS), occurred in the United States, Europe, and elsewhere.

Researchers identify new mechanism that protects from bacterial infections

An international team led by the University if Barcelona has identified a new antibacterial mechanism that protects macrophages - defense cells in the immune system- from the infection of the bacteria Salmonella enterica serovar Typhimurium, a pathogen associated with several gastrointestinal diseases.

Nicotine creates cascade of effects in the brain that get worse over time

The first period of nicotine abstinence proceeded as expected. The surprise came after three months when the lab rats suddenly became fearless and sought out well-lighted areas that prey animals normally avoid. At the same time, signaling in the brain's reward system changed, as shown by a study at Sahlgrenska Academy.

Blood test that spots tumor DNA predicts survival of advanced breast cancer patients

Results of a multicenter study of 129 women with advanced breast cancer show that a blood test that spots cancer-linked DNA correctly predicted that most of those patients with higher levels of the tumor markers died significantly earlier than those with lower levels.
