The transport of immunoglobulins across the intestinal mucosa of neonatal rats provides an excellent model for the study of transcellular protein transport. The mechanism of intestinal uptake and transcellular transport of plasma proteins has been studied in 12-14-day old rats using intraduodenally administered radioiodinated proteins. Appreciable quantities of rat IgG, mouse IgG, rabbit IgG, a...

BACKGROUND Magnetic resonance (MR) imaging of the neonate has been restricted by the need to transport the sick baby to the large magnetic resonance scanners and often the need for sedation or anaesthesia in order to obtain good quality images. Ultrasound is the reference standard for neonatal imaging. OBJECTIVE To establish a dedicated neonatal MR system and compare the clinical usefulness o...

Neonatal Cholestatic Liver Diseases Cholestatic liver disease in children occurs as a result of either an alteration in hepatocyte bile formation or disruption of bile flow out of the hepatocyte through intrahepatic bile ductules or extrahepatic bile ducts [1]. Liver disease usually appears within the first few weeks following birth. A large number of disorders exhibit cholestatic jaundice in n...

Homeostasis of riboflavin should be maintained by transporters. Previous in vitro studies have elucidated basic information about riboflavin transporter RFVT3 encoded by SLC52A3 gene. However, the contribution of RFVT3 to the maintenance of riboflavin homeostasis and the significance in vivo remain unclear. Here, we investigated the physiological role of RFVT3 using Slc52a3 knockout (Slc52a3-/-...

Arizona is a large state that has undergone profound population changes since the end of World War II. It has two major population centers (Phoenix and Tucson) that together account for approximately 75% of the state’s population. Much of the remaining population is found in small communities scattered throughout the state. There is a high Native American population, largely rural but with some...

Rab1 GTPase coordinates vesicle-mediated protein transport specifically from the endoplasmic reticulum (ER) to the Golgi apparatus. We recently demonstrated that Rab1 is involved in the export of angiotensin II (Ang II) type 1 receptor (AT1R) to the cell surface in HEK293 cells and that transgenic mice overexpressing Rab1 in the myocardium develop cardiac hypertrophy. To expand these studies, w...

BACKGROUND Many neonatal deaths can be prevented globally through effective resuscitation. South Africa (SA) committed towards attaining the Millennium Development Goal 4 (MDG4) set by the World Health Organization (WHO). However, SA's district hospitals have the highest early neonatal mortality rates. Modifiable and avoidable causes associated with patient-related, administrative and health ca...

there is an increased prevalence of maternal substance abuse during pregnancy in younger women in all socioeconomic classes and races. our aim was to determine the prevalence and correlates of self-reported substance abuse among pregnant women and obstetric complications or neonatal outcomes in iran. this retrospective cohort study is covering a five year period on medical records of pregnant w...
