A preliminary characterization of the didodecyldimethyl ammonium bromide (DDAB)/water (W)/per fluorooctane (PFO) ternary system at 25 degreesC is presented. The gradual addition of water, followed by mixing, to DDAB/PFO mixtures produces very stable emulsions for water contents greater than 20 wt%. On the basis of macroscopic observation, at least four different types of emulsions form up to a wat

The phylogeny of the cetrarioid lichens with bifusiform spermatia and dorsiventral thalli which contain usnic acid is reanalysed using three parts of the genome, ITS rDNA, b-tubulin and GAPDH sequences. Molecular data from five cetrarioid species are presented for the first time, and 13 new sequences are combined with sequences from the gene bank to delimit the genus Nephromopsis. A monophyletic c

Several metal complex agents have already been introduced into clinical tumor therapy and others are subject of antitumor studies. In this study we focused on the tetraaza macrocyclic copper complex (Cu(TAAB)Cl-2). We studied the influence of the substance on cell growth, cell cycle, membrane integrity, necrosis, apotosis and glutathione level on the leukemic cell line L1210 in 1-day (22 h) and 3-

Background. The aim was to evaluate whether patients with benign ovarian cysts, functional ovarian cysts, or endometriosis have an increased risk of developing gynecologic cancer. Methods. The Swedish Hospital Discharge Register was used to identify a cohort of women discharged from hospital with the diagnoses of ovarian cyst (n = 42 217), functional ovarian cyst (n = 17 998), or endometriosis (n

Pollen analyses and AMS C-14 measurements were performed on lacustrine sediments and peat deposits from the former crater lake Steregoiu in a mid-altitude area in the Gutaiului Mountains in NW Romania in order to provide a detailed reconstruction of the vegetational development of the area during the Late-Glacial and Holocene. The bottom sediments are siliciclastic and were deposited probably duri

We report on a sporadic case of Pfeiffer syndrome in a male newborn with complex craniosynostosis, broad thumbs and great toes and early demise. SSCP and direct sequencing revealed a missense mutation at position 1037 of the exon B (or IIIc) of the FGFR2 gene (codon 342) resulting in a cysteine to serine modification (TGC-TCC). Genotype-phenotype correlations between the FGFRs mutations and the di

OBJECTIVE: To study the possibility of improving blood lipids, glucose tolerance and insulin sensitivity in women with impaired glucose tolerance and a history of gestational diabetes by merely changing the glycaemic index (GI) and dietary fibre (DF) content of their bread. DESIGN: Randomized crossover study where test subjects were given either low GI/high DF or high GI/low DF bread products duri

A 10 mm gap in a rat sciatic nerve was bridged by a bioartificial nerve graft consisting of a silicone tube containing seven longitudinally placed filaments made of non-resorbable material (polyamide [Ethilon]) or resorbable materials (polydioxanon [PDS], polyglactin [Vicryl] or catgut). The purpose was to study the tissue reaction induced by the four different types of materials. At 4 weeks an im

Historik över hur de amerikanska filmbolagen flyttade sina inspelningar till Hollywood och sedan började bygga sina inspelningsanläggningar där. Men det handlar också om myternas Hollywood med filmstjärnefenomen och en nyrik, glamorös livsstil som påverkade världen.

Many of the core proteins in Photosystem II (PS II) undergo reversible phosphorylation. It is known that protein phosphorylation controls the repair cycle of Photosystem II. However, it is not known how protein phosphorylation affects the partial electron transport reactions in PS II. Here we have applied variable fluorescence measurements and EPR spectroscopy to probe the status of the quinone ac

We present an approximate Maximum Likelihood estimator for univariate Ito stochastic differential equations driven by Brownian motion, based on numerical calculation of the likelihood function. The transition probability density of a stochastic differential equation is given by the Kolmogorov forward equation, known as the Fokker-Planck equation. This partial differential equation can only be solv

Extensive experimental data from high-energy nucleus-nucleus collisions were recorded using the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC). The comprehensive set of measurements from the first three years of RHIC operation includes charged particle multiplicities, transverse energy, yield ratios and spectra of identified hadrons in a wide range of transverse momenta (PT), ellipt

In a previous study (van de Weijer 2003), it was shown that it is a relatively uncommon pattern to find two IC within the same monomorphemic word. The main purpose of the present study was to establish whether listeners have implicit knowledge of this aspect of phonological word structure. A lexical decision experiment was carried out in which subjects listened to nonsense words and real words in

The concentration-response relation for Ca2+ (0.2-5.0 mM) of high-K+ contractures (40 mM) in the rat portal vein during respiratory inhibition by 0.2 mM cyanide was investigated. A reduction of force in the presence of cyanide to about 30% of control was associated with a leftward shift of the normalized concentration-response relation. When force at the plateau of high-K+ contractures (at about 2

Neuronal ceroid lipofuscinoses (NCLs) represent a large group of inherited neurodegenerative disorders characterized by an abnormal accumulation of lipopigment in neuronal and extraneuronal cells. The authors present a case of juvenile neuronal ceroid lipofuscinosis in a 7-year-old boy. Ultrastructural examination of a skin biopsy disclosed deposits of curvilinear profiles and fingerprint-like str
