OBJECTIVE Diabetes, the leading cause of end-stage renal disease in the U.S., is believed to involve activation of the renin angiotensin system (RAS) as a risk factor for nephropathy. RAS activation occurs in healthy women using oral contraceptives (OCs), but the effects of OC use on the diabetic kidney are unclear. RESEARCH DESIGN AND METHODS Renal plasma flow (RPF) response to captopril, as...

An extended-release opioid analgesic (OxyContin, OC) was reformulated with abuse-deterrent properties to deter abuse. This report examines changes in abuse through oral and nonoral routes, doctor-shopping, and fatalities in 10 studies 3.5 years after reformulation. Changes in OC abuse from 1 year before to 3 years after OC reformulation were calculated, adjusted for prescription changes. Abuse ...

Bone remodeling occurs by the balanced action of bone resorbing osteoclasts (OC) and bone-building osteoblasts. Increased bone resorption by excessive OC activity contributes to malignant and non-malignant diseases including osteoporosis. To study OC differentiation and function, OC formed in in vitro cultures are currently counted manually, a tedious procedure which is prone to inter-observer ...

The aim of the study was to explain whether or not the time of ovarian cyst (OC) formation had an influence on reproductive performance in dairy cows. Eighty cows with OC (group A first OC diagnosis < 42 d postpartum; group B first OC diagnosis > 42 d postpartum) were compared with 80 control cows without OC matching in lactation number and calving date. Milk yield was higher in OC cows compare...

We describe the role of the octopamine-containing OC interneurons in the buccal feeding system of Lymnaea stagnalis. OC neurons are swallowing phase interneurons receiving inhibitory inputs in the N1 and N2 phases, and excitatory inputs in the N3 phase of fictive feeding. Although the OC neurons do not always fire during feeding, the feeding rate is significantly (P < 0.001) higher when both SO...

Background: Incubation of human whole blood at body temperature has been used in numerous studies without addition of glucose and insulin. The purpose of the study was to examine glucose concentration changes during in vitro incubation of human whole blood at different temperatures, and whether it was affected by addition of insulin and bacterial endotoxin. We also wanted to quantify changes in...

One of the main characteristics of obsessive-compulsive disorder (OCD) is the persistent feeling of uncertainty, affecting many domains of actions and feelings. It was recently hypothesized that OCD uncertainty is related to attenuated access to internal states. As supra-second timing is associated with bodily and interoceptive awareness, we examined whether supra-second timing would be associa...

MicroRNAs, a group of posttranscriptional regulators of numerous genes, are active participators during the development and progression of ovarian cancer (OC). This study confirmed for the first time that miR-216a was gradually increased in normal, benign, borderline, and OC tissues and that its expression was significantly upregulated in all OC cell lines. Analysis of its clinical association ...

Two monoclonal antibodies, OC 125 and OC 133, bind to distinct determinants on the surface of human epithelial ovarian carcinoma cell lines. OC 125 and OC 133 recognize determinants on molecules with molecular weights greater than 200,000 and 80,000, respectively. When binding to four different cell lines was compared, apparent affinity constants for OC 125 ranged from 3.1 X 10(9) to 6.0 X 10(7...

BACKGROUND Oropharyngeal colostrum (OC) application strategies have been shown to be feasible and safe for very low birth weight (VLBW) infants. Evidence to support the nutritional and clinical advantages of OC care remains somewhat theoretical. The objectives of this study were to a) confirm the feasibility and safety of OC application in preterm infants and b) determine if OC application is a...
