Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R1295– R1301, 1999.—Physiological responses at birth include increases in heart rate (HR), blood pressure, sympathetic nerve activity, and circulating vasoactive peptides. The fact...

setting, and an increasing number of emergency providers use point-of-care biliary sonography to rapidly evaluate symptomatic patients for the presence of cholelithiasis and its complications. Evaluation of elderly patients with suspected biliary sepsis is frequently complicated by altered mental status. In contrast to younger patients, sepsis from ascending cholangitis may be accompanied by at...

During pregnancy, maternal and fetal Ca demands are met through increased intestinal Ca absorption. Increased Ca absorption may be more dependent on oestrogen’s up-regulation of Ca transport genes than on vitamin D status. Numerous studies, however, have found that severe vitamin D deficiency with secondary hyperparathyroidism during pregnancy leads to abnormal Ca homoeostasis in the neonate. S...
