The effect of adding a Thermomyces (formerly Humicola) lanuginosa lipase (TLL) to a cubic dispersion of the binary monoolein (MO)-(H2O)-H-2 system and to vesicles formed by the ternary MO-sodium oleate (NaO)(H2O)-H-2 system at high water content has been studied. The change in lipid aggregate structure during the lipolytic process was observed by light microscopy, cryo-TEM, and dynamic light scatt
Background: The neonatal lupus syndrome can be present as congenital heart block (CHB) or as neonatal lupus erythematosus (NLE), both seldom passively acquired autoimmune diseases. CHB starts around week 20 of pregnancy and is a lifelong event, whereas NLE is self limiting and usually starts at the 6th week of the child's age - the maximum recorded up to week 20. Case report: An asymptomatic mothe
Regular octahedral coordination has been reported for some copper(II) complexes in the solid state on the basis of crystallographic studies, e.g. hexaaquacopper(II) bromate, [Cu(OH2)(6)](BrO3)(2). hexaaquacopper(II) hexafluorosilicate, [Cu(OH2)(6)]Si-6, and hexakis(pyridine-1-oxide)copper(II) perchlorate. [Cu(ONC5H5)(6)](ClO4)(2). These results are not consistent with the elongated octahedral conf
The effect of varying the fraction of charged monomer units of the polyion in aqueous polyion-oppositely charged surfactant complex salts has been investigated. The complex salts used were based on cetyltrimethylammonium (C(16)TA(+)) with three different polymeric counterions: poly(acrylate) (PA(-)) or poly(acrylate) copolymerized with either dimethylacrylamide (PA(-)/DAM) or N-isopropylamide (PA(
Release of cytotoxic granule proteins from activated eosinophil granules is considered to be a key pathogenic mechanism in eosinophilic diseases. Degenerated eosinophils and extracellular eosinophil granules have been repeatedly depicted. The present overview describes evidence that eosinophil lysis and distribution of free eosinophil granules (as opposed to 'classical degranulation') is an import
Objective: To identify the consequences of an anterior cruciate ligament (ACL) tear in a cohort of male soccer players 14 years after the initial injury with respect to radiographic knee osteoarthritis and patient relevant outcomes. Methods: Of 219 male soccer players with an ACL injury in 1986, 205 (94%) were available for follow up after 14 years; 75% of the cohort (154/205) answered mailed que
We describe the history, construction, and use of a portable walk-in wader trap (i.e., modified Ottenby trap) designed to be used in field expedition conditions. It is rectangular-shaped, 120 x 41 x 32 cm when operational, weighs between 1.5 and 2 kg (depending on materials used) and can be folded flat for easy transportation. It consists of several metal frames filled with fishing net, and has a
Dietary supplements, designed to fortify the antioxidant status of human metabolism, are intended to provide nutritional support against the aging process. The strategy is based on the observation that environmental and metabolic sources of oxidatively generated free radicals damage key macromolecules, such as DNA, that in turn alter physiologic processes, and in turn may contribute to aging and a
Previous work has shown that the lips are moving at a high velocity when the oral closure occurs for bilabial stop consonants, resulting in tissue compression and mechanical interactions between the lips. The present experiment recorded tongue movements in four subjects during the production of velar and alveolar stop consonants to examine kinematic events before, during, and after the stop closur
Antigenicity, the ability to bind to members of repertoire of diverse immune receptors, is a concept that is poorly characterised with respect to its defining parameters. To learn more about its makeup, we have investigated the ability of two peptides with highly related sequences, derived from the tumour-associated antigen mucin-1, to recruit in vitro members from a large naive repertoire of synt
When heating a dilute sample of the binary system of tetraethyleneglycol dodecyl ether (C12E4) and water from the micellar phase (L-1) into the two-phase region of a lamellar phase (L-alpha) and excess water (W) vesicles are formed. During heating, one passes a region of phase separation in the micellar phase (L-1' + L-1") where the initial micelles rapidly fuse into larger aggregates forming the
Macroscopic phase separation in covalent sodium polyacrylate (PA) networks following the absorption of cetyltrimethylammonium bromide/chloride (CTAB/C) from aqueous solutions is studied experimentally and theoretically. The gels are shown to consist of a solvent-swollen polyelectrolyte network (core), surrounded by a dense surface phase (skin) of polyion/surfactant complexes. The effect of core sw
Galectins are a group of lactose-binding proteins widely distributed in nature. Twelve mammalian galectins have so far been identified, but their functions are to a large extent unknown. In this work we study galectin-1 in its interaction with human neutrophils, with regard to both cell surface binding and activation of the superoxide-producing NADPH-oxidase. We show that galectin-1 is able to act

This book provides (a) the first comprehensive description of the phonology and phonetics of Standard Mongolian, known as the Halh (Khalkha) dialect and spoken in Ulaanbaatar, the capital of the Republic of Mongolia; and (b) the first account in any language of the historical phonology of the Mongolian group of languages. The synchronic phonology is based on data collected by the authors and on th
This paper describes a long term, high-resolution study of the activityof the Perseid meteor stream based on visual and radar observations atthe Onsala Space Observatory in Sweden. The data consists of 147 visualhourly rates and 1368 radar hourly rates. In a previous paper (Lindblad2000) a high-resolution study of the visual zenithal hourly rates ofbright Perseid meteors versus solar longitude was
This paper reviews means for fatigue damage rates estimation using Laplace distributed multiaxial loads. The model is suitable for description of stresses containing transients of random amplitudes and locations. Explicit formulas for computing the expected value of rainflow damage index as a function of excess kurtosis are given for correlated loads. A Laplace model is used to describe variabilit
