Popliteal cyst (Baker’s cyst) was first described by Adams in 1840, popularized by Baker in 1877, and was theorized as an enlarged gastrocnemiussemimembranosus bursa that communicated with the knee and trapped synovial fluid.1 Numerous bursa are located in the popliteal space between the knee ligaments, hamstring tendons, gastrocnemius muscle, and collateral ligaments. The two proposed etiologi...

Thirty-eight muscles of the beef chuck and round were histochemically stained to characterize fiber-type composition in order to facilitate optimal muscle use in value-added products. Select-grade chucks and rounds (n = 4 each) were chosen to represent two carcass weight classes (250 to 295 kg and 363 to 410 kg) and two yield grades (1 and 3). Muscles were sectioned and stained with a procedure...

Aim of study: To evaluate the physicochemical and sensory quality meat from Santa Inês × Dorper lambs fed diets with increasing levels sunflower cake.
 Area Rio Grande do Norte (Brazil).
 Material methods: Twenty-four castrated (initial weight 18.9 ± 2.17 kg) were distributed in a completely randomized design four treatments (0, 5, 10 15% cake diet) six repetitions kept confinement un...

Forty USDA Select and 40 upper two-thirds USDA Choice beef carcasses were used to determine the effects of postmortem aging on tenderness of 17 individual beef muscles. Biceps femoris-long head, complexus, gluteus medius, infraspinatus, longissimus dorsi, psoas major, rectus femoris, semimembranosus, semitendinosus, serratus ventralis, spinalis dorsi, supraspinatus, tensor fasciae latae, teres ...

The effect of rapid air chilling of carcasses, compared to conventional air chilling, and effect of earlier deboning, after rapid air chilling, on colour of pork M semimembranosus was investigated. During and at the end of chilling, compared to conventional chill treatment, carcasses that were rapid chilled had significantly (P < 0.001) lower internal temperature in the deep leg. Rapid chilled ...

The effects of origin, gender, age, and muscle type on chemical composition, colour, antioxidant status and sensory profile of reindeer muscles Longissimus dorsi (LD) and Semimembranosus (SM) from two production regions were investigated. For some variables, the comparison between reindeer and beef muscles was also included. Muscles from North Norway (NN) were darker and contained more myoglobi...

BACKGROUND Advancement in technology of computer tomography (CT) and introduction of new medical imaging softwares enables easy and rapid assessment of muscle cross-sectional area (CSA) and attenuation. Before using these techniques in clinical studies there is a need for evaluation of the reliability of the measurements. The purpose of the study was to evaluate the inter- and intra-observer re...

The aim of this study was to investigate the myogenic factor mRNA expression pattern of Pax7, Myf5, MyoG, and Myostatin mRNA at different ages, sexes, and muscle tissues of Datong yaks. The expression patterns in semimembranosus (SM), quadriceps femoris (QF), and triceps muscle of arm (TM) were detected by quantitative real-time polymerase chain reaction and compared using biostatistics. The re...

Intramuscular fat is an important quality trait in pork. Lysine and protein have been reported to influence this trait, but most studies have modified both factors simultaneously. In this study, the effects of dietary Lys and protein were investigated in finishing pigs to determine if either of the 2 factors alone or in combination influence the deposition of intramuscular fat. One hundred and ...
