Questions: The pelvic girdle with associated spines is an integrated anti-predator defence apparatus, and is assumed to protect against piscivores in the threespine stickleback. On the other hand, it might be costly to produce the pelvic apparatus in ion-poor and mineralchallenging freshwater. Hypothesis: Stickleback with a reduced pelvic apparatus should use more shelter and be more nocturnal,...

An 18 year old man presented with persistent exercise-induced muscle cramps of 6 months duration. He reported no change in the color of his urine. The patient was the third of four children born to consanguineous parents (first-degree cousins) of Jewish Iraqi origin. His early development was entirely l imb girdle muscular dystrophy is the collective name for a diverse group of disorders charac...

Abstract Rioraja agassizii belongs to the monotypic genus and differs from other Riorajini species of Atlantoraja by shape anterior nasal flap, squamation, clasper skeleton, body measurements color pattern. Although R. is a well-known species, commonly captured in inshore waters southwestern Atlantic, its external morphology internal anatomy have never been fully described little known on intra...

Teleost fish genomes are known to be evolving faster than those of other vertebrate taxa. Thus, fish are suited to address the extent to which the same vs. different genes are responsible for similar phenotypic changes in rapidly evolving genomes of evolutionary independent lineages. To gain insights into the genetic basis and evolutionary processes behind parallel phenotypic changes within and...

A sub-group of pelvic girdle pain (PGP) patients with a positive active straight leg raise (ASLR) responds positively to the application of external pelvic compression during the test. This study investigated the effect of this phenomenon on electromyographic (EMG) activity of the trunk muscles and intra-abdominal and intra-thoracic pressures in subjects with a unilateral sacroiliac joint (SIJ)...

During pregnancy, high progesterone and relaxin levels produce physiological ligament relaxation on the pelvis. Therefore, moderate pubic symphysis and sacroiliac joints relaxing provide birth canal widening, thereby facilitating vaginal delivery. Sometimes, functional pain or pelvic instability may occur during pregnancy or puerperium, which is defined as symptomatic pelvic girdle relaxation. ...

Owls are known as silent predators of the night due to quietness of their flight. Capturing prey without any noise, that would be detectable by the owl’s prey is maintained by several features in its body and wing system. Wing bones are well developed than the pelvic limb bones. The pelvic girdle is small and contained a deep renal fossa. The fovea capitis is very much prominent on the head of ...
