One of the most toxic effects of organophosphate (OP) poisoning has been the paralysis of skeletal muscles that can lead to paralysis of respiratory muscles and death. However, oximes are the only antidotes available to reverse or prevent such toxic effects of OP insecticides and nerve chemical warfare agents. In the present research work, the effect of different concentrations of paraoxon (as ...

Of the two known vasoactive intestinal peptide receptors (VPAC1R and VPAC2R), the VPAC2R is expressed in skeletal muscle. To evaluate the function of the VPAC2R in the physiological control of skeletal muscle mass, we utilized the VPAC1R selective agonist [K15,R16,L27]VIP(1-7) GRF(8-27)-NH2 and the VPAC2R selective agonist Ro-25-1553 to treat mice and rats undergoing either nerve damage-, corti...

Skeletal muscle tissue engineering (SMTE) aims to repair or regenerate defective skeletal muscle tissue lost by traumatic injury, tumor ablation, or muscular disease. However, two decades after the introduction of SMTE, the engineering of functional skeletal muscle in the laboratory still remains a great challenge, and numerous techniques for growing functional muscle tissues are constantly bei...

BACKGROUND The expression of multiple cardiac troponin T (cTnT) isoforms has been demonstrated in diseased human skeletal muscle. However, cardiac troponin I (cTnI) expression has been described only in heart muscle. The goal of this study was to determine whether mRNA for cTnT, slow skeletal troponin T (sTnT), or cTnI was expressed in skeletal muscle biopsies obtained from patients with end-st...

Skeletal muscle contains one of the largest and the most dynamic pools of Na,K-ATPase (NKA) in the body. Under resting conditions, NKA in skeletal muscle operates at only a fraction of maximal pumping capacity, but it can be markedly activated when demands for ion transport increase, such as during exercise or following food intake. Given the size, capacity, and dynamic range of the NKA pool in...

rhabdomyosarcomas are the most common soft tissue sarcoma in adult and children that accompany with skeletal muscle differentiation. skin metastasis of rhabdomyosarcomas is unusual and has only been sporadically reported in literature. in this paper we present a case of skin metastasis of rhabdomyosarcoma in an 8-year-old girl that has treated with chemotherapy.

Diffusion tensor magnetic resonance imaging (DTI) is increasingly applied in the detection and characterization of skeletal muscle. This promising technique has aroused much enthusiasm and generated high expectations, because it is able to provide some specific information of skeletal muscle that is not available from other imaging modalities. Compared with conventional MRI, DTI could reconstru...

Skeletal muscle comprises approximately 40% of body weight, and is important for locomotion, as well as for metabolic homeostasis. Adult skeletal muscle mass is maintained by a fine balance between muscle protein synthesis and degradation. In response to cytokines, nutrients, and mechanical stimuli, skeletal muscle mass is increased (hypertrophy), whereas skeletal muscle mass is decreased (atro...

The purpose of present review is to describe the effect of leucine supplementation on skeletal muscle proteolysis suppression in both in vivo and in vitro studies. Most studies, using in vitro methodology, incubated skeletal muscles with leucine with different doses and the results suggests that there is a dose-dependent effect. The same responses can be observed in in vivo studies. Importantly...
