Human studies have not assessed corticospinal excitability of an upper-limb prime mover during arm cycling. The purpose of the present study was to determine whether supraspinal and/or spinal motoneuron excitability of the biceps brachii was different between arm cycling and an intensity-matched tonic contraction. We hypothesized that spinal motoneuron excitability would be higher during arm cy...

we investigated sexual size dimorphism in the tree frog, hyla savignyi using 33 males and 22 females from the western and northwestern regions of kermanshah province, western iran. out of sixteen measured morphometric characters, four were significantly larger in females than in males. these characters were nostrileye length, brachium length, elbowlongest finger length and hind limb length.

Composite tissue allotransplantation (CTA) now represents a valid therapeutic option after the loss of a hand, forearm or digits and has become a novel therapeutic entity in reconstructive surgery. However, long term high-dose multi-drug immunosuppressive therapy is required to ensure graft survival, bearing the risk of serious side effects which halters broader application. Further progression...

The purpose of this study was to simultaneously isolate skeletal muscle plasma and microsomal membranes from the hind limbs of male Sprague-Dawley rats perfused either in the absence or presence of 20 milliunits/ml insulin and to determine the effect of insulin on the number and distribution of glucose transporters in these membrane fractions. Insulin increased hind limb glucose uptake greater ...

muscular disease which affects the hind limb in young cattle (Baird et al., 1974; Harper, 1993). It is recorded in Holstein, Freisian and other breeds (Baird et al., 1974; Harper, 1993). This disease resulted from the contraction of the gastrocnemius and superficial flexor digital muscles and in some cases, the biceps femoris, semitendinosus, semimembranosus, quadriceps and abductor muscles (Wi...

Three-dimensional musculoskeletal models have become increasingly common for investigating muscle moment arms in studies of vertebrate locomotion. In this study we present the first musculoskeletal model of a western lowland gorilla hind limb. Moment arms of individual muscles around the hip, knee and ankle were compared with previously published data derived from the experimental tendon travel...

Most mammals use lateral sequence gaits during quadrupedal locomotion, a pattern characterized by the touchdown of a forelimb directly following the ipsilateral hind limb in a given stride cycle. Primates, however, tend to use diagonal sequence (DS) gaits, whereby it is the touchdown of a contralateral forelimb that follows that of a given hind limb most closely in time. A number of scenarios h...

Background: Management of lymphedema is a challenging issue in surgery.  A variety of operations have been used, albeit with little success. Objective: To investigate the efficacy of testicular patch as a lymphatic conduit. Methods: An incision was made on the inguinal area of 10 dogs and all lymph nodes of inguinal area were excised. The tunica albuginea and parenchyma near the hilum of testes...
