1(2)-Aryl-5-methylsulfonyltetrazoles react with ethylene glycol, di- and triethylene glycols, and tris(2-hydroxyethyl)amine in acetonitrile in the presence of sodium hydroxide to give tetrazole-containing ethers. The products can be used as polydentate ligands for biomimetic studies.

Large and small interstitial proteoglycans were purified from different bovine tissues, i.e. cartilage, sclera, tendon, aorta, cornea, and bone. The structure of the molecules was compared using the glycerol spraying/rotary shadowing technique for electron microscopy. Large proteoglycans from sclera and tendon have a core protein with a domain structure similar to that previously reported for cart

KIT is a tyrosine kinase receptor expressed by several tumours, which has for specific ligand the stem cell factor (SCF). KIT is the main oncogene in gastrointestinal stromal tumours (GISTs), and gain-of-function KIT mutations are present in 70% of these tumours. The aim of the study was to measure and investigate the mechanisms of KIT activation in 80 KIT-positive GIST patients. KIT activation wa

This study describes the evaluation and characterization of a self-nanoemulsifying drug delivery system (SNEDDS) consisting of a nonionic surfactant (Cremophor RH40), a mixture of long chain mono-, di-, and triacylglycerides (Maisine 35-1 and Sesame oil) and ethanol. Compositions containing 10% (w/w) ethanol, 40%-60% (w/w) lipid content, and 30%-50% (w/w) Cremophor RH40 were identified as pharmace

Sediment sequences retrieved from Lake Medvedevskoye (60degrees13'N 29degrees54'E) and Lake Pastorskoye (60degrees13'N, 30degrees02'E). Karelian Isthmus, northwestern Russia, were analysed for lithology, pollen and diatom stratigraphy, total organic carbon content and mineral magnetic parameters. Age control for both sequences was provided by AMS C-14 measurements and the Vedde Ash tephra. The rec

The Moraxella catarrhalis IgD-binding protein (MID) has a unique specificity for human IgD, and the sequence with maximal IgD binding is located within the amino acids MID962-1200. In the present paper, we examined the MID binding site on IgD using a series of recombinant Ig. Full-length IgD, IgD F(ab')(2), and an IgD F(ab') C290R mutant lacking the inter-heavy-chain cysteine 290 were manufactured

The circadian variation of pheromone production in the turnip moth, Agrotis segetum, was characterized by quantifying (Z)-7-dodecenyl acetate (Z7-12:OAc), the most abundant pheromone component produced by female turnip moth, at different times of day. Under 17:7 h light-dark cycle (LD), the peak of Z7-12:OAc production occurred around 4 h into the scotophase, while there was very little pheromone

The structural effect on the metal-to-ligand charge transfer (MLCT) excited-state lifetime has been investigated in bis-tridentate Ru(II)-polypyridyl complexes based on the terpyridine-like ligands [6-(2,2'-bipyridyl)](2-pyridyl)methane (1) and 2-[6-(2,2'-bipyridyl)]-2-(2-pyridyl)propane (2). A homoleptic ([Ru(2)(2)](2+)) and a heteroleptic complex ([Ru(ttpy)(2)](2+)) based on the new ligand 2 hav

In this paper, we analyze the experiences gained from tradable green certificate (TGC) schemes and extract some policy lessons that can lead to a successful design of a market-based approach for energy efficiency improvement, alias tradable white certificate schemes. We use tradable green certificate schemes existing in the Netherlands and Sweden as case studies. Departing from an assessment of bo

Objective: To compare two models of learning the pelvic examination (PE) for medical students, with professional patients (PP) or with clinical patients (CP), by measuring perceived distress and learning outcome in terms of skills. Methods: Prospective longitudinal study. Assessments of self-perceived distress on four occasions at the prospect of performing a PE. Evaluation of the learning session

Purpose Human papillomavirus (HPV) has been linked to oropharyngeal carcinomas, but its role in laryngeal squamous cell carcinoma (LSCC) is not clear. A prospective multicenter study based on known tumor-cell percentage of fresh frozen carcinoma biopsies was established to determine the HPV prevalence. Moreover risk factors such as smoking, alcohol abuse, chronic laryngitis and gastroesophageal re

Recent findings indicate that the interactions among CO2, temperature and water can be substantial, and that the combined effects on the biological systems of several factors may not be predicted from experiments with one or a few factors. Therefore realistic multifactorial experiments involving a larger set of main factors are needed. We describe a new Danish climate change-related field scale ex

Objective: To examine whether blood pressure over 24 h differed between postmenopausal women receiving and not receiving hormone replacement therapy. Methods: One group of hormone replacement postmenopausal women (n = 32) and one group of non-hormone replacement (n = 32) postmenopausal women underwent non-invasive 24-h ambulatory blood pressure monitoring. They were randomly selected among the 200

Study Objective: To determine whether Postoperative wound infiltration with local anesthetics combined with fentanyl improves analgesia following breast surgery; and to investigate awakening and Postoperative nausea/vomiting. Design: Prospectively randomized clinical study. Setting: University hospital. Patients: 45 ASA physical status I and II patients scheduled for breast surgery. Interventions:

The association of cytochrome c oxidase negative fibres (COX-negative) and ragged-red fibres (RR-fibres) with work related trapezius myalgia has been proposed. Hitherto studies have been small or without control groups. The aim of the present study was to investigate the prevalences of RR-fibres and COX-negative fibres in female cleaners with (n=25) and without (n=23) trapezius myalgia and in clin
