“Atrogin-1 and MuRF1, muscle-specific

ubiquitin ligases, and autophagy selleck chemical play a role in protein degradation in muscles. We hypothesized that branched-chain amino acids (BCAAs) may decrease atrogin-1, MuRF1, and autophagy, and may have a protective effect on disuse muscle atrophy. To test this hypothesis, we selected hindlimb suspension (HS)-induced muscle atrophy as a model of disuse muscle atrophy because it is an established model to investigate the effects of decreased muscle activity. Sprague-Dawley male rats were assigned to 4 groups: control, HS (14 days), oral BCAA administration (600 mg/[kg day], 22.9% L-isoleucine, 45.8% L-leucine, and 27.6% L-valine), and HS and BCAA administration. After 14 days of the treatment, muscle weights and protein concentrations, cross-sectional area (CSA) of the muscle fibers, atrogin-1 and MuRF1 proteins, and microtubule-associated protein 1 light chain 3 II/I (ratio of LC3 II/I) were measured. Hindlimb suspension

significantly reduced soleus muscle weight and CSA of the muscle fibers. Branched-chain amino acid administration partly but significantly reversed the HS-induced decrease

in CSA. Elacridar clinical trial Hindlimb suspension increased atrogin-1 and MuRF1 proteins, which play a pivotal role in various muscle atrophies. Branched-chain amino acid attenuated the increase in atrogin-1 and MuRF1 in soleus muscles. Hindlimb suspension significantly Selleckchem FK506 increased the ratio of LC3 II/I, an indicator of autophagy, whereas BCAA did not attenuate the increase in the ratio of LC3 II/I. These results indicate the possibility that BCAA inhibits HS-induced muscle atrophy, at least in part, via the inhibition of the ubiquitin-proteasome pathway. Oral BCAA administration appears to have the potential to prevent disuse muscle atrophy. (C) 2012 Elsevier Inc. All rights reserved.”
“Each set of conjoined twins presents a unique challenge, which centers on the ability to separate and if necessary reconstruct shared organs and to achieve subsequent skin cover of the often very large residual defect after completion of the separation. This report describes the use of a bioprosthetic Permacol(A (R)) derived from porcine dermal collagen to reconstruct the chest and abdominal wall.”
“Background: The dedicated devices for blood irradiation are available only at a few centers in developing countries thus the irradiation remains a service with limited availability due to prohibitive cost.
