Opioids interact with sympathetic and renin-angiotensin systems in control of mean arterial pressure (MAP). Our earlier finding that biphalin, a synthetic enkephalin analogue, decreased MAP in anaesthetized spontaneously hypertensive rats (SHR) prompted us to further explore this action, to get new insights into pathogenesis of various forms of hypertension. Biphalin effects were studied in SHR, uninephrectomized rats on a high-salt diet (HS/UNX), and rats with angiotensin-induced hypertension (Ang-iH). Besides MAP, renal and iliac blood flows (RBF, IBF) and vascular resistances were measured...

The present study characterized natural killer cells and cytokines in diabetic mothers, their placenta, and fetus. In the maternal blood from the hyperglycemic groups, the CD16(+)CD56(-) NK cells increased, whereas that of CD16(+)CD56(+) decreased in gestational diabetes mellitus [GDM] group. Cord blood from type 2 diabetes [DM-2] showed a higher proportion of CD16(+)CD56(-) and CD16(-)CD56(+). The placental extravillous layer of GDM and DM-2 showed an increase of CD16(+)CD56(-) cells and, irrespective of region, the proportion of CD16(-)CD56(+) cells was higher in mild gestational hyperglycemia [MGH] and GDM and lower in DM-2...

Elevated roxarsone (ROX) concentrations in soils, caused by land application of ROX-bearing poultry litter, mandate investigation of ROX sorption onto soils. Equilibrium and kinetic studies of ROX sorption onto five soils were carried out to explore the relationship between sorption parameters and soil properties, and to reveal the effects of coexisting humic acid (HA), P(V), As(V), and As(III) on ROX transport. Experimental results indicated that ROX sorption reached equilibrium within 24 h, with pseudo-second order rate constants of 5...

INTRODUCTION: In Uganda, an estimated 120 obstetrician/gynecologists serve a population of 30 million people demonstrating the need to train additional skilled clinician leaders in reproductive health. In 2012, a partnership was formed with the Mbarara Regional Referral Hospital (MRRH) in southwest Uganda and the Massachusetts General Hospital (MGH) in Boston, USA, in part to increase access to specialist training. This report presents an update in the development of a teaching conference between the institutions...

Introduction The science underpinning mass-gathering health (MGH) is developing rapidly. However, MGH terminology and concepts are not yet well defined or used consistently. These variations can complicate comparisons across settings. There is, therefore, a need to develop consensus and standardize concepts and data points to support the development of a robust MGH evidence-base for governments, event planners, responders, and researchers. This project explored the views and sought consensus of international MGH experts on previously published concepts around MGH to inform the development of a transnational minimum data set (MDS) with an accompanying data dictionary (DD)...

BACKGROUND: It is unknown whether clinical performance during residency is related to the American Board of Anesthesiology (ABA) oral examination scores. We hypothesized that resident clinical performance would be independently associated with oral examination performance because the oral examination is designed to test for clinical judgment. METHOD: We determined clinical performance scores (Zrel) during the final year of residency for all 124 Massachusetts General Hospital (MGH) anesthesia residents who graduated from 2009 to 2013...

OBJECTIVES: The entity of 'surface epithelial changes' (SECs) was first described in 1995 [1]. Morphologically, SECs usually arise from malignant glands at the superficial aspect of well differentiated (WD) endometrioid carcinomas (ECs) and impart the appearance of a 'maturational' phenomenon at the surface of the cancer. Exhibiting a paradoxically bland histologic appearance, SECs typically show morphologic features that mimic benign entities, particularly endocervical microglandular hyperplasia (MGH)...

BACKGROUND: Although pathology informatics (PI) is essential to modern pathology practice, the field is often poorly understood. Pathologists who have received little to no exposure to informatics, either in training or in practice, may not recognize the roles that informatics serves in pathology. The purpose of this study was to characterize perceptions of PI by noninformatics-oriented pathologists and to do so at two large centers with differing informatics environments. METHODS: Pathology trainees and staff at Cleveland Clinic (CC) and Massachusetts General Hospital (MGH) were surveyed...

PURPOSE: The implementation of a required residency rotation in transitions of care (TOCs) and the resulting resident-led clinical interventions and learning experiences are described. SUMMARY: A newly required four-week TOC rotation was implemented for postgraduate year 1 (PGY1) pharmacy residents at Massachusetts General Hospital (MGH). Unlike acute care rotations, this learning experience encouraged residents to focus on providing direct patient care in a holistic manner and use pharmacologic and nonpharmacologic strategies to improve patient outcomes...

Growth hormone (GH), together with thyroid hormones (TH), regulates growth and development, and has critical effects on vertebrate metabolism. In ectotherms, these physiological processes are strongly influenced by environmental temperature. In reptiles, however, little is known about the direct influences of this factor on the somatotropic and thyroid axes. Therefore, the aim of this study was to describe the effects of both acute (48h) and chronic (2weeks) exposure to sub-optimal temperatures (25 and 18°C) upon somatotropic and thyroid axis function of the green iguana, in comparison to the control temperature (30-35°C)...
