Chromium-induced toxicity and mechanisms of cell death involved in plants are yet to be fully elucidated. To understand the events of these processes, the stress response of the soybean plant using trivalent and hexavalent chromium compounds, namely, basic chromium sulphate (BCS) and potassium dichromate (K2Cr2O7) was investigated. The leaf surface morphology for stomatal aperture, wax deposition and presence of trichomes for chromium accumulation was examined by SEM-EDAX and light microscopy. The leaf mesophyll cell integrity was identified by trypan blue staining; chlorophyll autofluorescence, ROS generation and mitochondrial function were studied by fluorescence microscopy using different dyes...

BACKGROUND: Methotrexate (MTX) is the standard first-line therapy in rheumatoid arthritis (RA) with variable clinical efficacy that is difficult to predict. The glycosylation status of immunoglobulin G (IgG) is altered in RA and influenced by MTX treatment. We aimed to further investigate if IgG glycosylation in untreated early RA can predict therapeutic response to MTX. METHODS: We used a shotgun proteomic approach to screen for the Fc glycopeptides in the serum of 12 control subjects and 59 untreated patients with early RA prior to and following MTX initiation...

BACKGROUND: Insufficient physical activity [PA] is a risk factor for several noncommunicable diseases [NCDs]. The World Health Organisation stresses the need for national PA trend data to help inform strategies to arrest NCD incidence. The Active Australia Survey [AAS] questionnaire quantifies leisure-time physical activity [LTPA]. Despite being used repeatedly in large population surveys, these data have never been analysed as a single dataset. This study established temporal trends for aerobic PA sufficiency prevalences in the Australian adult [18-75+ years] population, 2002-2012, based on LTPA...

Posttraumatic stress disorder (PTSD) is associated with poorer performance on neuropsychological tests in veterans. However, prior studies have generally compared individuals with PTSD to control groups, often excluding individuals with moderate symptoms. The present study evaluated neuropsychological performance among OEF/OIF/OND veterans as a function of overall PTSD severity, while also exploring potential associations between cognitive performance and PTSD symptom clusters. Using a brief neuropsychological battery, clinical interviews, and self-report instruments, we evaluated neuropsychological and psychiatric functioning in 90 OEF/OIF/OND veterans...

REVIEW
Yonah Krakowsky, Abraham Morgentaler
CONTEXT: When luteinizing hormone-releasing hormone (LHRH) agonists were introduced in the 1980s, it was universally believed that the initial transient rise in serum testosterone (T), termed T flare, caused rapid prostate cancer (PCa) growth and led to disease progression, complications, and death. It became routine to offer antiandrogens (AAs) to prevent these risks. However, over the last decade, it has become recognized that androgens have a finite ability to stimulate PCa growth (the saturation model), providing a theoretical challenge to the risks of T flare...
