Differential proteomic and behavioral effects of long-term voluntary exercise in wild-type and APP-overexpressing transgenics.

Physical exercise may provide protection against the cognitive decline and neuropathology associated with Alzheimer's disease, although the mechanisms are not clear. In the present study, APP/PSEN1 double-transgenic and wild-type mice were allowed unlimited voluntary exercise for 7months. Consistent with previous reports, wheel-running improved cognition in the double-transgenic mice.

Oral cancer: enduring characteristics and emerging trends.

Oral cancer is arguably the most serious condition that dental providers may encounter in their practice. The relatively poor prognosis associated with oral cancer highlights the importance of the dental team's awareness of the disease. While many characteristics of oral cancer have endured over time, new research is revealing trends that are changing the way we approach its screening, diagnosis and treatment.

A survey of glioblastoma genomic amplifications and deletions.

Glioblastoma Multiforme (GBM) is a malignant brain cancer that develops after accumulating genomic DNA damage that often includes gene amplifications and/or deletions. These copy number changes can be a critical step in brain tumor development. To evaluate glioblastoma genomic copy number changes, we determined the genome-wide copy number alterations in 31 GBMs.

Biochemical changes induced in liver and serum of diplodiatoxin (Stenocarpella maydis) treated male and female rats.

Present study was conducted to investigate the acute and sub-acute toxic effect of diplodiatoxin with special reference to biochemical membrane bound enzymes like aspartate aminotransferase (ASAT), alanine aminotransferase (ALAT) and RBC acetylcholinesterase (AChE) in male and female rats. For acute study, rats were treated with a single oral dose of 5.7 mg/kg of diplodiatoxin, whereas for sub-acute study, the rats received 0.

Effect of diplodiatoxin (Stenocarpella maydis) on some enzymatic profiles in male and female rats.

Acute and subacute effects of diplodiatoxin were monitored with special reference to biochemical target enzymes like acid phosphatase (AcP), alkaline phosphatase (AkP), and acetylcholinesterase (AChE) in male and female rats. For acute toxicity study the rats were treated with single oral dose of 5.7 mg/kg of diplodiatoxin, whereas for subacute toxicity study the rats were orally treated with 0.
