Testosterone may help heart failure patients: Study

The researchers used testosterone patches and injections that improved the breathing and exercise abilities of people with heart failure, a chronic inability of the heart to pump enough blood to the rest of the body. Although most of the study participants were men, the researchers said the results would likely apply to women as well, through much smaller doses of testosterone.

Engineered particles tied to penetratin discover, deliver ligands for mitochondria, ribosomes

Scientists who developed a technology for identifying and targeting unique protein receptor ZIP Codes on the cellular surface have found a way to penetrate the outer membrane and deliver engineered particles - called iPhage - to organelles inside the cell.

Tumor microenvironment contributes critically to drug response

It should be possible to significantly improve the response of common cancers to existing "classical" chemotherapy drugs, say scientists at Cold Spring Harbor Laboratory (CSHL), by introducing agents that alter the interaction of cancer cells with their immediate surroundings, called the tumor microenvironment.

Study: Kidney cancer growth depends on autophagy

New research at the University of Cincinnati (UC) suggests that kidney cancer growth depends on autophagy, a complex process that can provide cells with nutrients from intracellular sources. Researchers say in certain circumstances autophagy can protect tumor cells from chemotherapy, allowing them to survive for long periods of time in a hidden, dormant, metastatic state.

Changes in thromboxane synthase may lead to hypertension in women with preeclampsia

Virginia Commonwealth University School of Medicine researchers have discovered that changes in the gene expression of a key enzyme may contribute to high blood pressure and increase susceptibility to forming blood clots in pregnant women with preeclampsia.

New technique could help improve prognosis of patients with brain cancers

Like special-forces troops laser-tagging targets for a bomber pilot, tiny particles that can be imaged three different ways at once have enabled Stanford University School of Medicine scientists to remove brain tumors from mice with unprecedented accuracy.

Study: Stem cells from pelvic bone marrow may help hearts beat stronger

Stem cells from the pelvic bone may help hearts beat stronger. Doctors and other clinicians at the Orlando Health Heart Institute are researching the use of stem cells from pelvic bone marrow to restore tissue and improve heart function after muscle damage from heart attacks.

Eye test to detect heart disease early

Scientists at the University of Edinburgh have developed the test which scans blood vessels in the retina at the back of the eyes. They are now launching a study involving more than 1,000 patients to see if the test is reliable.

FDA ‘ups’ safety warnings for blood clots on birth control pill labels

According to federal health regulators more information needs to be added to labels on a popular class of birth control pills that includes Bayer AG's Yaz and Yasmin, to show they may raise the risk of blood clots. A clot in blood vessels can prove fatal if it breaks loose and travels to the lungs, heart or brain.

Study provides guidelines on how to combine antiangiogenic drugs with nanotherapeutics

Combining two strategies designed to improve the results of cancer treatment - antiangiogenesis drugs and nanomedicines - may only be successful if the smallest nanomedicines are used. A new study from Massachusetts General Hospital (MGH) researchers, appearing in Nature Nanotechnology, finds that normalizing blood vessels within tumors, which improves the delivery of standard chemotherapy drugs, can block the delivery of larger nanotherapy molecules.

Researchers question wisdom of blocking DP1 in patients prone to cardiovascular disease

Niacin, or vitamin B3, is the one approved drug that elevates "good" cholesterol (high density lipoprotein, HDL) while depressing "bad" cholesterol (low density lipoprotein , LDL), and has thereby attracted much attention from patients and physicians. Niacin keeps fat from breaking down, and so obstructs the availability of LDL building blocks.

Inflammasome involved in regulating Age-Related Macular Degeneration

Scientists at Trinity College Dublin have discovered that a part of the immune system called the inflammasome is involved in regulating the development of one of the most common forms of blindness, called Age-Related Macular Degeneration.

VCAM1 nanobodies can effectively visualize atherosclerotic lesions

In collaboration with a Brussels University team under the leadership of Nick Devoogdt and a French team from INSERM, Serge Muyldermans and his team, associated with VIB and Vrije Universiteit Brussel, have succeeded in developing the first patient-friendly, non-invasive method for differentiating dangerous strictures in blood vessels, so-called vulnerable atherosclerotic plaques, from less dangerous ones.
