Unobtrusive clots: Video of blood clot contraction reveals platelets mechanism

The first view of the physical mechanism of how a blood clot contracts at the level of individual platelets is giving researchers from the Perelman School of Medicine at the University of Pennsylvania a new look at a natural process that is part of blood clotting. A team led by John W. Weisel, a professor of Cell and Developmental Biology, describes in Nature Communications how specialized proteins in platelets cause clots to shrink in size.

Defect in Zinc Transport Mechanism Causes Pulmonary Diseases

The researchers of Kumamoto University , Japan have shown that abnormalities of the epithelial sodium ion (Na + ) channel ( ENaC ) and cystic fibrosis transmembrane conductance regulator ( CFTR ) reduces the body's ability to deliver zinc ions (Zn2 +) to lung epithelial cells. The insufficient zinc supply to the lung epithelial cells causes the overproduction of mucus , leading to the development of the obstructive pulmonary diseases.

Diagnosis of Two Cancer Types Using IR Spectroscopy

A new study published in the journal Scientific Reports revealed that two types of cancer (lymphoma and melanoma) could be detected with a simple blood test using infrared (IR) spectroscopy. The findings suggested that IR spectroscopy could detect biochemical changes induced by non-Hodgkin's lymphoma (a solid tumorous condition of the immune system), and subcutaneous melanoma, (the deadly form of skin cancer), and has diagnostic potential as a screening technique for these cancers.

Study Shows Exercise Alone may not Protect Your Knees

Obese people who lose a substantial amount of weight can slow down the degeneration of their knee cartilage, but only if they lose weight through diet and exercise or dietary alone, according to a new MRI study presented today at the annual meeting of the Radiological Society of North America (RSNA).
