Sprouting of bladder nerves into cystoplastic cecal segment in the rat.
Incorporation of bowel into the bladder (enterocystoplasty) has been widely used to increase bladder capacity. It has been reported by others that the response of smooth muscle from the cystoplastic segment of the intestine shifts from that of the intestine (relaxation to α-agonists and ATP) to that of the bladder (contraction to α-agonists and ATP). This suggests a functional integration of the i
Novel nanoelectronic device applications based on the nonlinearity of three-terminal ballistic junctions
Nanometer-scale electron devices containing three-terminal ballistic junctions are fabricated by electron-beam lithography on InP/InGaAs two-dimensional electron gas materials. Based on the intrinsic nonlinearity of the devices, frequency mixer, phase detector and RS flip-flop memory functioning at room temperature are successfully achieved. The devices have simple structure layout and small size,
First records of Microptila Ris (Trichoptera: Hydroptilidae) from Japan, with description of a new species
Microptila orienthula, sp. n. from Japan is described and illustrated based on adults of both sexes. The new species represents the first finding of Microptila in the Eastern Palaearctic Region, and it appears to be more closely related to Oriental species of Microptila than to the two Western Palaearctic species. The finding of a new species with affinities to the Oriental species as far northeas
Cerebral ischemia induces transcription of inflammatory and extracellular-matrix-related genes in rat cerebral arteries.
Cerebral ischemia results in a local inflammatory response that contributes to the size of the lesion, however, the involvement of the cerebral vasculature is unknown. We hypothesise that the expression of inflammatory genes (Il6, iNOS, cxcl2, TNF-α and Il-1β) and extracellular-matrix-related genes (MMP9, MMP13) is induced in cerebral arteries following cerebral ischemia via activation of mitogen
Medical education in Libya: The challenges
The history of medical education in Libya spans over a period of 40 years. Medical schools had a good and promising start in the 1970s. The graduates of the first few classes had a good impact on the health services in Libya. However, the medical schools did not embrace the immense changes that medical education experienced over the last two decades. This article aims to give a background on the m
Protein Kinase C delta Supports Survival of MDA-MB-231 Breast Cancer Cells by Suppressing the ERK1/2 Pathway
Mechanisms that mediate apoptosis resistance are attractive therapeutic targets for cancer. Protein kinase C delta (PKC delta) is considered a pro-apoptotic factor in many cell types. In breast cancer, however, it has shown both pro-survival and pro-apoptotic effects. Here, we report for the first time that down-regulation of PKC delta per se leads to apoptosis of MDA-MB-231 cells. Inhibition of M

Vitamin D as Supplementary Treatment for Tuberculosis A Double-blind, Randomized, Placebo-controlled Trial
Rationale Vitamin D has been shown to be involved in the host immune response toward Mycobacterium tuberculosis. Objectives: To test whether vitamin D supplementation of patients with tuberculosis (TB) improved clinical outcome and reduced mortality. Methods: We conducted a randomized, double-blind, place-bocontrolled trial in TB clinics at a demographic surveillance site in Guinea-Bissau. We incl
Influence of glucose and insulin on transcapillary fluid absorption from the arm during lower body negative pressure in man
This study examined the influence of insulin and glucose on the transcapillary fluid absorption during lower body negative pressure (LBNP) in humans. Ten healthy males [23 (1) years] were exposed to LBNP of 45 cmH(2)O on two occasions: (1) before and during a hyperinsulinaemic clamp (HI) and (2) before and during a hyperglycaemic clamp (HG). Transcapillary fluid absorption and blood flow were reco
Fats infused intraduodenally affect the postprandial secretion of the exocrine pancreas and the plasma concentration of cholecystokinin but not of peptide YY in growing pigs
In pigs, the spontaneous secretion of the exocrine pancreas and the release of cholecystokinin (CCK) and peptide YY (PYY) after intraduodenal infusion of fully saturated synthetic fats differing in chain length was studied. Growing pigs (n = 6) were prepared with pancreatic duct catheters, duodenal T-cannulas and catheters placed in the jugular vein. The pigs were fed 2 g/100 g body twice daily. B
Human reconstituting hematopoietic stem cells up-regulate Fas expression upon active cell cycling but remain resistant to Fas-induced suppression.

Gene expression profiling of Escherichia coli expressing double Vitreoscilla haemoglobin
In a recent investigation, expression of a double Vitreoscilla haemoglobin (two fused VHb molecules) in Escherichia coli grown in shake flasks resulted in higher final cell density and considerably higher levels of ribosomes and tRNA. In this study, we have investigated the E. coli transcriptome in cells expressing native VHb, double VHb and control cells lacking VHb by hybridising mRNA from the d
Usage of antifungal drugs for therapy of genital Candida infections, purchased as over-the-counter products or by prescription: 2. Factors that may have influenced the marked changes in sales volumes during the 1990s.
Effects of Ischemia-Reperfusion Injury on Apolipoprotein M Expression in the Liver
The present study investigated the expression pattern of apolipoprotein M (apoM) mRNA in a rat model of hepatic ischemia-reperfusion injury (IRI). Animals were ischemic for I hour followed by various reperfusion times. As expected, serum alanine aminotransferase levels were significantly increased under IRI, which indicated the severity of liver injury. Hepatic mRNA levels of HSP70, which is the m
Thromboprophylaxis with a low molecular weight heparin (tinzaparin) in emergency abdominal surgery. A double-blind multicenter trial
In this prospective randomized double-blind study the thromboprophylactic effect of postoperative low molecular weight heparin (tinzaparin) was compared with placebo in 80 patients undergoing emergency abdominal surgery. The fibrinogen uptake test was used but because of withdrawal of the labelled fibrinogen from the market the calculated number of patients was not reached. However, this is one of
Effects of dexamethasone on clinical course, C-reactive protein, S100B protein and von Willebrand factor antigen after paediatric cardiac surgery.
Monitoring of Saccharomyces cerevisiae Cell Proliferation on Thiol-Modified Planar Gold Microelectrodes Using Impedance Spectroscopy.
An impedance spectroscopic study of the interaction between thiol-modified Au electrodes and Saccharomyces cerevisiae of strain EBY44 revealed that the cells formed an integral part of the interface, modulating the capacitive properties until a complete monolayer was obtained, whereas the charge transfer resistance ( R ct) to the redox process of [Fe(CN)6] (3-/4-) showed a linear relationship to t
Absolute quantification of cerebral blood flow in neurologically normal volunteers: Dynamic-susceptibility contrast MRI-perfusion compared with computed tomography (CT)-perfusion
To improve the reproducibility of arterial input function (AIF) registration and absolute cerebral blood flow (CBF) quantification in dynamic-susceptibility MRI-perfusion (MRP) at 1.5T, we rescaled the AIF by use of a venous output function (VOF). We compared CBF estimates of 20 healthy, elderly volunteers, obtained by computed tomography (CT)-perfusion (CTP) and MRP on two consecutive days. MRP,
