the environmental scanning electron microscopy (esem) is a new development in the field of electron microscopy. in this study esem has been used to study the structure of veal semimembranosus muscle. four treatments, raw (control), conventional heating, domestic and industrial microwave heating, were observed using esem. the temperature used in conventional heating was 163 0c. frequency app...

BACKGROUND Our knowledge of the stability of the posteromedial knee is evolving. The distal semimembranosus is an important posteromedial stabilizer of the knee. Current anatomical texts and atlases do not accurately detail the distal insertion. Journal literature commonly mentions multiple distal insertions, one of which contributes to the oblique popliteal ligament. The purpose of this study ...

Forty-eight Yorkshire cross pigs of three stress susceptibility classes (stress positive, stress-carrier, and stress negative) were injected daily with porcine somatotropin (pST; 4 mg/d) or placebo. Each pig was injected in the neck once daily until taken off test, starting when the pigs weighed 59 kg. Porcine somatotropin treatment was terminated at weekly intervals as individual pigs reached ...

Exercise training improves functional capacity in aged individuals. Whether such training reduces the severity of exercise-induced muscle damage is unknown. The purpose of the present study was to determine the effect of 10 wk of treadmill exercise training on skeletal muscle oxidative capacity and exercise-induced ultrastructural damage in six aged female Quarter horses (>23 yr of age). The ma...

Our objectives were to determine how beef hot carcass weights relate temperature and pH decline, Warner-Bratzler shear force, objective color of steaks from the longissimus thoracis semimembranosus. Beef carcasses (N = 59) selected at a commercial plant based on weight separated into either light- (< 363 kg), medium- (364–407 or heavy-weight (> 408 kg) groups. Temperature in semi-...

This prospective cohort study described return-to-play (RTP) data for different types of muscle injuries in male elite-level football players in Europe. Eighty-nine European professional teams were followed between 2001 and 2013. Team medical staff recorded individual player exposure and time-loss injuries. A total of 17,371 injuries occurred, including 5603 (32%) muscle injuries. From 2007, we...

The hamstring muscle group consists of three muscles in the posterior thigh; the semitendinosus (ST) and the semimembranosus (SM) are located at the medial side, the biceps femoris at the lateral side (BF) [1]. The biceps femoris has two heads, which are anatomically and functionally distinct; the short (BFsh) and the long (BFlh) head. The semitendinosus and long head of the biceps femoris have...

The purpose of this study was to determine whether increased muscle activity could reverse myosin structural alterations that occur in aged rat muscle and whether those alterations could be induced in young rat muscle by decreased activity. Semimembranosus muscle activity was increased by electrical stimulation (200-ms trains, 154 Hz, 5 V) through a nerve cuff on the tibial branch of the ischia...
