OBJECTIVE The purpose of this study was to assess the diagnostic correlation between indirect MR arthrography, conventional MRI, and arthroscopy in acetabular labral and cartilage lesions of the hip. MATERIALS AND METHODS Fourteen patients who underwent conventional and indirect MR arthrography with arthroscopic correlation were studied over the course of(More)
The flexor femoris muscle complex (FFMC) is also known as the hamstring muscle complex or commonly as the "hamstrings." Three muscles comprise this group: the biceps femoris, the semitendinosus, and semimembranosus. The FFMC is one of the most frequent sites of muscle injury. Hamstring injuries are becoming more common secondary to the increase in society's(More)
Two experiments were conducted in consecutive years in which recently (Experiment 1) or temporarily (Experiment 2) weaned ewes and matched post-partum non-lactating flockmates (DRY) were exposed to a stimulus group of rams and oestrous ewes (10 and 20 in Experiment 1, 20 and 20 in Experiment 2) for 28 days in spring. Lactating ewes (n = 130) in Experiment 1(More)
Serial blood sampling before and after exposing four anovular Corriedale ewes to a group of rams and estrous ewes during the non-breeding season revealed a pattern of LH secretion similar to that previously observed in Merinos. Mean LH values doubled (P<0.001) from 0.24+/-0.06 microgL(-1) (mean+/-s.e.m.) before to 0.55+/-0.05 microgL(-1) after 2h of visual,(More)
When induced to ovulate during anoestrus, ewes, does and cows frequently develop a short-lived corpora lutea (SLCL) syndrome associated to lack of previous progesterone. Exogenous progesterone precludes SLCL by blocking oxytocin endometrial receptors, thus inducing normal life-span CL (NLCL). Paradoxically, circa 50% of unprimed ewes do not develop SLCL. We(More)
