Vardenafil-induced relaxation and cyclic nucleotide levels in normal and obstructed rat urinary bladder.

OBJECTIVE To study the effects of the phosphodiesterase-5 inhibitor, vardenafil, on contraction and cyclic nucleotide levels in isolated detrusor preparations with and without mucosa, from control rats and rats with partial urethral obstruction (PUO) and intact mucosa. MATERIALS AND METHODS Female Sprague-Dawley rats were divided into groups subjected to PUO for 14 days (six), and sham-operated co

Multilevel Exploratory Factor Analysis of the Feeling Word Checklist-24.

Emotional reactions are a vital part of the therapeutic relationship. The Feeling Word Checklist-24 (FWC-24) is an instrument asking the clinician (or the patient) to report to what degree he or she has experienced various feelings during a therapeutic interaction. The aim of this study was to assess the factor structure of the clinician-rated FWC-24 when taking dependencies in the data into accou

Territory quality affects the relative importance of habitat heterogeneity and interference competition in a long-lived territorial songbird

Density-dependent reproduction is commonly explained by either the habitat heterogeneity (HHH) or individual adjustment (IAH) hypothesis. Under the HHH, high quality territories are assumed to be occupied first. At higher density, occupation of low-quality territories increases due to lower availability of high-quality territories, which reduces mean reproductive success. Alternatively, the IAH as

Binding of albumin promotes bacterial survival at the epithelial surface.

Albumin (HSA) is the dominating protein in human plasma. Many bacterial species, especially streptococci, express surface proteins that bind HSA with high specificity and affinity, but the biological consequences of these protein-protein interactions are poorly understood. Group G streptococci (GGS), carrying the HSA-binding protein G, colonize the skin and the mucosa of the upper respiratory trac

Differential expression of Axl and Gas6 in renal cell carcinoma reflecting tumor advancement and survival.

PURPOSE: Overexpression of the receptor tyrosine kinase Axl is implicated in several cancers. Therefore, we conducted this study to determine the expression of Axl and its ligand Gas6 in various renal cell carcinoma (RCC) types and in oncocytoma. EXPERIMENTAL DESIGN: Real-time quantitative reverse transcription-PCR was used to quantify tumor mRNA levels for Axl and Gas6 in a cohort (n = 221) of RC

Large fat and skin necroses after deep subcutaneous injections of a slow-release somatostatin analogue in a woman with acromegaly.

OBJECTIVE: Somatostatin analogues are the most commonly used drugs for treatment of acromegaly. Known side effects include gastrointestinal reactions, cholelithiasis, effects on glucose metabolism, and mild reactions at injection sites. We report a patient who developed fat and skin necroses after injections of a depot somatostatin analogue. SUBJECT: A woman with active acromegaly was given deep s

Extensive dinoflagellate phylogenies indicate infrequent marine-freshwater transitions

We have constructed extensive 18S–28S rDNA dinoflagellate phylogenies (>200 sequences for each marker) using Maximum Likelihood and Bayesian Inference to study the evolutionary relationships among marine and freshwater species (43 new sequences). Our results indicated that (a) marine and freshwater species are usually not closely related, (b) several freshwater species cluster into monophyletic gr

Daily dosing prophylaxis for haemophilia: a randomized crossover pilot study evaluating feasibility and efficacy.

Regular replacement therapy (prophylaxis) for haemophilia has been shown to prevent development of disabling arthropathy and to provide a better quality of life compared to treatment on demand; however, at a substantially higher cost. Calculations based on pharmacokinetic principles have shown that shortening dose intervals may reduce cost. The aim of this prospective, randomized, crossover pilot

Natural history of radiographic hip osteoarthritis: A retrospective cohort study with 11-28 years of followup.

Abstract OBJECTIVE: To evaluate the association between radiographic hip osteoarthritis (OA) and future total hip replacement (THR) due to OA or hip fracture. METHODS: We studied a cohort of individuals who had colon radiography from 1980-1997. Minimal joint space (MJS) was measured and each hip was graded for radiographic OA according to the Kellgren/Lawrence scale. Subjects were followed until t

How similar are semantic categories in closely related languages? A comparison of cutting and breaking in four Germanic languages

Are the semantic categories of very closely related languages the same? We present a new methodology for addressing this question. Speakers of English, German, Dutch and Swedish described a set of video clips depicting cutting and breaking events. The verbs elicited were then subjected to cluster analysis, which groups scenes together based on similarity (determined by shared verbs). Using this te

Oral Assessment Guide - test of reliability and validity for patients receiving radiotherapy to the head and neck region.

Radiotherapy to the head and neck region leads to severe side effects in the oral cavity but knowledge about severity and onset is scarce among oncology nurses in a radiotherapy department. The aim was to test the Oral Assessment Guide for reliability and validity for patients receiving radiotherapy to the head and neck region. A prospective design with repeated assessments was selected. Thirty-si

Influence of Maternal and Paternal Birthweight on Offspring Birthweight - a Population-based Intergenerational Study.

The correlation between infant birthweight and parental birthweight has received substantial interest. However, fewer studies including the birthweight of the father have had access to large sets of population-based data. The objective of this study is to examine the influence of maternal and paternal birthweight on the birthweight of the offspring in the context of other birthweight determinants,

Establishment of the first World Health Organization International Genetic Reference Panel for quantitation of BCR-ABL mRNA.

Serial quantitation of BCR-ABL mRNA levels is an important indicator of therapeutic response for patients with chronic myelogenous leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia, but there is substantial variation in the real-time quantitative polymerase chain reaction methodologies used by different testing laboratories. To help improve the comparability of results bet

Macroscopic studies of short-pulse high-order harmonic generation using the time-dependent Schrodinger equation

We consider high harmonic generation by ultrashort (27-108 fs) laser pulses and calculate the macroscopic response of a collection of atoms to such a short pulse. We show how the harmonic spectrum after propagation through the medium is significantly different from the single-atom spectrum. We use single-atom data calculated by integration of the time-dependent Schrodinger equation and propose a m

Time and place in the prehistory of the Aslian languages

The Aslian language family, located in the Malay Peninsula and southern Thai Isthmus, consists of four distinct branches comprising some 18 languages. These languages predate the now dominant Malay and Thai. The speakers of Aslian languages exhibit some of the highest degree of phylogenetic and societal diversity present in Mainland Southeast Asia today, among them a foraging tradition particularl

Involvement of Ngn2, Tbr and NeuroD proteins during postnatal olfactory bulb neurogenesis.

Postnatal neurogenesis takes place in two brain regions, the hippocampus and the subventricular zone (SVZ). The transcriptional cascade controlling hippocampal neurogenesis has been described in detail; however, the transcriptional control of olfactory bulb neurogenesis is still not well mapped. In this study, we provide insights into the molecular events controlling postnatal olfactory bulb neuro
