BACKGROUND The proximity of the outflow tracts (OTs) frequently results in an overlap in surface electrocardiographic features of ventricular arrhythmias originating from this anatomic region, particularly when the transition occurs in lead V3. In addition, no reliable criteria to discriminate between a right ventricular OT (RVOT) and a left ventricular OT (LVOT) site of origin (SOO) are derive...

We evaluated whether Gonadotrophin releasing hormone incorporation to the Human chorionic gonadotropin protocol improves the sexual response during the natural anestrous season in goats. Thirty-two adult multibreed anovulatory goats (n = 8, four groups), received 20 mg progesterone i.m. on d-1; on d0, all goats received 7.5 mg prostaglandin F i.v. and control group (CG) 0.5 mL of saline i.m., h...

INTRODUCTION Elevated circulating non-esterified fatty acids including oleic acid (OA) are associated with many pregnancy related complications. Prostaglandins (PGs) play crucial roles during parturition. We investigated the effect of OA supplementation on PG production using an in vitro model of ovine placenta. METHODS Maternal endometrium (ME) and fetal allantochorion (FC) were collected in...

The hypothalamic synthetic pathway of oxytocin (OT) involves the synthesis of carboxy-extended forms that serve as intermediate prohormones. We hypothesized that extended forms of OT are synthesized in the late-gestational rat uterus and that they compete for OT receptor binding. Parturition occurs only when the ratio of OT to its extended forms reaches a critical level. We have measured OT and...

Neurotoxicities of dibutyltin (DBT), tin(II) octylate (OT), poly-L-lactides (PLLA, molecular weight [MW]=5000, PLLA 5000), PLLA without tin (MW=3000, PLLA 3000), PLLA with a large amount (590 ppm) of tin (S3), poly(glycolic acid-co-epsilon-caprolactone) oligomer (MW=6200, PGC oligomer), and poly(L-lactic acid-co-glycolic acid-co-epsilon-caprolactone) oligomer (MW=6400, PLGC oligomer) related to...

Last summer, AAAI sponsored a mobile robot competition in conjunction with the AAAI-92 conference in San Jose, California. Ten robots from across the country competed in the competition, with CARMEL from the University of Michigan finishing first. CARMEL is a Cybermotion K2A mobile platform with a ring of 24 sonar sensors and a single black and white CCD camera. For computing, CARMEL has three ...

BACKGROUND Nausea and vomiting after transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) are common in clinical practice, but few studies have reported the incidence and risk factors of such events. OBJECTIVE The purpose of this study was to analyze the incidence and risk factors of nausea and vomiting after TACE for HCC. METHODS This study was a single-center...

INTRODUCTION We evaluated the effect of different syringe volume, needle size and sample volume on blood gas analysis in syringes washed with heparin. MATERIALS AND METHODS In this multi-step experimental study, percent dilution ratios (PDRs) and final heparin concentrations (FHCs) were calculated by gravimetric method for determining the effect of syringe volume (1, 2, 5 and 10 mL), needle s...
