Chromogenic in situ hybridization can identify ALK rearrangement in lung cancer patients

A relatively simple and inexpensive method may be used to determine whether a lung cancer patient is a candidate for crizotinib therapy, according to research published in the August issue of the Journal of Thoracic Oncology, the official monthly journal of the International Association for the Study of Lung Cancer.

Combination molecules with BRAF inhibitors may help overcome drug resistance in melanoma patients

About 50 to 60 percent of patients with melanoma have a mutation in the BRAF gene that drives the growth of their cancer. Most of these patients respond well to two novel agents being studied in clinical trials that inhibit the gene, with remarkable responses that are, unfortunately, almost always limited in duration.

Insight into how brain organizes during development

Scientists at the Allen Institute for Brain Science have taken an important step in identifying how the brain organizes itself during development. The findings, published in the Journal of Comparative Neurology today, describe - in more detail than ever before - the consequences of the loss of a key molecule involved in establishing proper brain architecture during brain development.

Mood-related brain protein linked to sadness during cigarette withdrawal

Heavy smokers may experience sadness after quitting because early withdrawal leads to an increase in the mood-related brain protein monoamine oxidase A (MAO-A), a new study by the Centre for Addiction and Mental Health (CAMH) has shown. This finding, which was published in the Archives of General Psychiatry, may also explain why heavy smokers are at high risk for clinical depression.

Researchers sample hydrogenotrophic microbes in the healthy human colon

They make up less than one-hundredth of 1 percent of the microbes that live in the colon, but the bacteria and archaea that sop up hydrogen in the gut are fundamental to colon health. In a new study, researchers take a first look at these "hydrogenotrophic" microbes, mapping where they live and how abundant they are in different parts of the lower intestine.

New insights into genesis and development of Sézary syndrome

Scientists at Charité - Universitätsmedizin Berlin, Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, the Max-Planck-Institut für Molekulare Genetik Berlin, and four other German institutes succeeded in proving a specific gene loss in a certain human lymphoma, the genesis of which is largely unexplained to date.

Conference to focus on connection between fluid balance and hypertension

Each day we consume liquids in order to keep hydrated and maintain our body's fluid balance. But just as a water balloon can get overtaxed by too much liquid, the human body is negatively affected when it retains fluids because it is unable to eliminate them properly. One of the key variables influencing how much fluid we hold in our bodies is ordinary table salt.

Hydrogen sulfide protects blood vessels from diabetes complications

Hydrogen sulfide is a foul-smelling gas with an odor resembling that of rotten eggs. Sometimes called "swamp gas," this toxic substance is generally associated with decaying vegetation, sewers and noxious industrial emissions. And - as odd as it may seem - it also plays a critical role in protecting blood vessels from the complications of diabetes, according to a new study from the University of Texas Medical Branch at Galveston.
