Certain bacteria suppress production of toxic shock toxin: Probiotic potential looms Posted: 22 Mar 2013 09:54 AM PDT Certain Streptococci increase their production of toxic shock syndrome toxin 1, sometimes to potentially dangerous levels, when aerobic bacteria are present in the vagina. But scientists have discovered certain strains of lactobacillus bacteria are capable of dampening production of that toxin.

Immune-cell therapy could strengthen promising melanoma treatment Posted: 22 Mar 2013 07:43 AM PDT Scientists have used newly developed nanotechnology chips (multidimensional and multiplexed immune monitoring assays) to successfully monitor T cells genetically engineered to attack melanoma. They have discovered that the T cells change over time when returned to patients. These results will help improve engineered immunotherapy for melanoma and the assays will help understand a spectrum of other cellular immunotherapies in the future.

Blocking an inflammation pathway prevents cardiac fibrosis, study suggests Posted: 22 Mar 2013 07:43 AM PDT New research shows that blocking an enzyme that promotes inflammation can prevent the tissue damage following a heart attack that often leads to heart failure.

Spatial memory: Mapping blank spots in the cheeseboard maze Posted: 22 Mar 2013 07:42 AM PDT During learning, novel information is transformed into memory through the processing and encoding of information in neural circuits. Scientists have now uncovered a novel role for inhibitory interneurons in the rat hippocampus during the formation of spatial memory.

Men and women get sick in different ways: Developing gender-specific medicine is a major challenge of the future Posted: 22 Mar 2013 06:08 AM PDT Recent research in laboratory medicine has revealed crucial differences between men and women with regard to cardiovascular illness, cancer, liver disease, osteoporosis, and in the area of pharmacology.

Long nerve grafts restore function in patients with brachial plexus injury Posted: 22 Mar 2013 06:03 AM PDT A new study challenges a widely held belief that long nerve grafts do poorly in adults with an axillary nerve injury. Investigators found that the outcomes of long nerve grafts were comparable to those of modern nerve transfers.
