The hamstring muscles and tendons are the most commonly injured muscle group in athletes. The hamstring tendons are particularly vulnerable to injuries, as they cross 2 joints and have a high proportion of type 2 muscle fibers. They act mainly as decelerators of the leg, and as they work eccentrically, they are prone to excessive force in the muscle-tendon unit. Most hamstring injuries are stra...

Thymoma is the most common thymic epithelial tumor whose classification was first introduced in 1999. Type B2 thymoma is considered a moderate/high-risk tumor; however, extrathoracic metastases are extremely rare with limited reports to date. In this report, we present a rare thymoma metastasis to the semimembranosus muscle, which was resected with a wide margin after confirmation by open biops...

While the age-related loss in muscle mass partially explains the decline in strength, other yet undefined mechanisms contribute. This study investigates whether changes in myosin-actin stoichiometry and oxidative modification could help explain the decrement in muscle strength with aging. Protein expression and oxidation were evaluated in myosin and actin isolated from the soleus and semimembra...

We report a rare case of a 'giant ganglion' with 24 x 10 x 12 cm dimensions originating from the semimembranosus tendon. The patient presented with chronic pain and a palpable mass in his left calf located between the superior aspect of the popliteal fossa and the distal third of the calf. MRI revealed the mass to be a ganglion in close relation to the semimembranosus muscle at its attachment t...

Proximate data, consumer palatability scores and volatile compounds were investigated for four beef muscles (Longissimus lumborum, Psoas major, Semimembranosus and Gluteus medius) and five USDA quality grades(Prime, Upper 2/3 Choice, Low Choice, Select, and Standard). Quality grade did not directly affect consumer scores or volatiles but interactions (P < 0.05) between muscle and grade were det...

This study aimed to describe the multivariate structure of Semimembranosus muscle and backfat fatty acid (FA) composition in 798 Italian Large White heavy pigs investigate effects environmental factors carcass characteristics on FA variations. The total variability was characterized by a negative correlation between saturated polyunsaturated FAs, which strongly depended adiposity. Slaughtering ...

Intramuscular fat percentage (IMF%) has been shown to have a positive influence on the eating quality of red meat. Selection of Australian lambs for increased lean tissue and reduced carcass fatness using Australian Sheep Breeding Values has been shown to decrease IMF% of the Muscularis longissimus lumborum. The impact this selection has on the IMF% of other muscle depots is unknown. This study...

BACKGROUND Purchasing pork that is boned within 1 h postmortem and not aged is customary in China, and final pork color would not be fully realized. The relationship between early postmortem, pre-rigor meat color and 24 h postmortem, post-rigor pork color was investigated and related to the rate of pH and temperature decline within the longissimus dorsi (LD) and the semimembranosus (SM) muscles...

This study aimed to determine the effect of high-intensity ultrasound (HIU. F = 37 kHz, I 28W/cm2, bath for 30 min, 5 °C) on physicochemical characteristics and sensorial preference seven aged (23 d ageing) bovine muscles (L. dorsi lumborum, L. thoracis, Psoas major, Semimembranosus, Biceps femoris, Rectus Gluteus medius). Muscles were randomly distributed in two treatments: with without ultras...
