Variation in the serotonin transporter gene-linked polymorphic region (5-HTTLPR) has been associated with heightened neural activity in limbic and prefrontal regions in response to emotional stimuli. The current study examined whether the 5-HTTLPR polymorphism is also associated with alterations in microstructure of frontal-limbic white matter (WM) tracts.(More)
Despite the growing interest in enhancing the cultural awareness for nurse practitioner (NP) students who work with patients from the developing world, there is a dearth of reports on such experiences. This report describes the clinical experiences of NP students from George Mason University (Fairfax, VA) during an intensive 2 weeks in Nicaragua in their(More)
BACKGROUND Renal replacement therapies which consist of renal transplantation and dialysis are the only treatment options for patients with terminal renal failure. These therapies have changed the outcome from being fatal to being a chronic disease. Kidney transplantation involves the use of immunosuppressive agents to prevent rejection. Currently, several(More)
Factors which allow the adaptation of adult llamas to oxygen limitation include principally: low P50, small elliptical red cells with high hemoglobin concentration, high muscle myoglobin concentration, high capillary density and a more efficient O2 extraction at tissue levels. The fetal llama is known to have blood with a low P50 but it is not known whether(More)
The objective of our study was prospectively compare the effect in the rate of cesarean section of active labor management and of traditional labor management in primiparas with physiological term pregnancy. From september 1, 1993 to may 31, 1994, 145 primiparas with physiological term pregnancy were randomly assigned to one group of active labor management(More)
The cardiovascular response to H in fetal llam (Lama glama) is characterized by an intense vascoconstriction of the carcass, kidneys and gut. In fetal sheep this response is partially mediated by catecholamines and arginine-vasopressim. A simultaneous increase in plasma ACTH and cortisol (F) is also observed. Since the llama has evolved at 4000 meters shove(More)
Thyrotropin Releasing Hormone (THR) induce fetal pulmonary maturation by direct stimulation, and increase of fetal T3 and T4 which produce biochemical and structural pulmonary maturation. To evaluate the effectivity of TRH associated to corticoides in the prevention of respiratory distress syndrome (RDS) in premature labor, we administered TRH plus Cidoten(More)
