The aim of the study was to determine the contents of mineral elements (Ca, K, Mg, Na, P, Cu, Fe, Mn, Cd, Pb, and Se), vitamins (B(1), B(2), B(12), C, D, folates, and niacin), and certain phenolic compounds (flavonoids, lignans, and phenolic acids) in the cultivated mushrooms Agaricus bisporus/white, Agaricus bisporus/brown, Lentinus edodes, and Pleurotus ostreatus. Selenium, toxic heavy metals (Cd, Pb), and other mineral elements were analyzed by ETAAS, ICP-MS, and ICP methods, respectively; vitamins were detected by microbiological methods (folates, niacin, and vitamin B(12)) or HPLC methods (other vitamins), and phenolic compounds were analyzed by HPLC (flavonoids) or GC--MS methods (lignans and phenolic acids). Cultivated mushrooms were found to be good sources of vitamin B(2), niacin, and folates, with contents varying in the ranges 1.

Otitis media with effusion (OME) is characterized by persistent effusion in the middle ear cavity and by chronic inflammation in the middle ear mucosa. Alloiococcus otitidis, a gram-positive aerobic bacterium, has been isolated in middle ear effusion, and by means of sensitive polymerase chain reaction detection assays it has been detected in as many as 20% of middle ear aspirates of patients with OME. Because A otitidis may freely interact with leukocytes in the middle ear effusion, it may potentially modulate the inflammatory reaction in OME.

Fucosylation of glycans on glycoproteins and -lipids requires the enzymatic activity of relevant fucosyltransferases and GDP-L-fucose as the donor. Due to the biological importance of fucosylated glycans, a readily accessible source of GDP-L-fucose would be required. Here we describe the construction of a stable recombinant S.

The aim of the present study was to establish a threshold for the initial displacement of a spiral tibial shaft fracture beyond which its retention in an acceptable position cannot be guaranteed by plaster immobilization. We reviewed the records and radiographs of 131 plaster cast-treated patients with spiral tibial shaft fracture, initially displaced 50% or less, for patients whose fracture had either lost its acceptable retention or consolidated in an unacceptable position. The fractures were classified, according to the true initial displacement as measured on the first radiographs, into four pairs of categories using cut-off points of 10, 20, 30 and 40% of the diameter of the tibial diaphysis.

Adenoidectomy in children with otitis media with effusion reduces inflammation in the middle ear by an unknown mechanism. Potentially, the adenoids of these children may serve as a site for the differentiation of lymphocytes, which after entering blood circulation eventually extravasate in the middle ear mucosa and thereby contribute to excessive inflammation. During lymphocyte extravasation various adhesion molecules and chemokines play a crucial role.

In-line connected electrochemical (EC) and diode array (DAD) detectors were compared in the reversed-phase high-performance liquid chromatographic (RP-HPLC) analysis of coenzymes Q(9) and Q(10) in some food materials (beef steak, beef heart, Baltic herring fillet, and rye flour). Coenzymes Q(9) and Q(10) were extracted from the samples using a 5:1 n-hexane-ethanol mixture. Coefficient of variation (CV%) of quadruplicate or quintuplicate determined samples for coenzymes Q(9) and Q(10) was <10 by both EC detector and DAD.

The predominant source of vitamin D is the synthesis of cholecalciferol in the skin by the action of sunlight; however, due to the relative lack of sunlight, the intake of vitamin D from food is emphasized during winter, especially in the northern countries. Only a few foods (fish, eggs, wild mushrooms, meat, and milk) are natural sources of vitamin D. In addition, the content of vitamin D in foods is generally low, and some groups of people obtain amounts of vitamin D that are too small from their diet.

It has been suggested that dystrophic neurites in the hippocampal CA2-3 sector are characteristic of diffuse Lewy body disease (DLBD) but not of Parkinson's disease (PD). We investigated the severity of neuritic change in the CA2-3 sector of the hippocampus and in the periamygdaloid cortex (PAC) in 45 patients with clinically diagnosed and neuropathologically verified PD. Samples from amygdala, hippocampus, entorhinal cortex (ERC) and cortical gyri were examined for Alzheimer-type (AD) changes and Lewy bodies (LBs) using antibodies against ubiquitin and tau.

L-selectin guides lymphocytes into peripheral lymphoid tissues by recognizing glycoprotein ligands decorated with 6-sulfated sialyl Lewis x (sulfo sLex). Here we have used a rat peripheral lymph node high endothelial cell line (Ax) to study in detail the synthesis, expression and degradation of sLex epitope. We show here that Ax cells possess active alpha(1,3)fucosyltransferase Fuc-TVII, the enzyme responsible for the final fucosylation of sialyl-N-acetyllactosamine during sLex synthesis, and express sLex on the cell surface.

We determined the apolipoprotein E (apoE) genotype in clinically diagnosed and neuropathologically verified cases of Parkinson's disease (PD) (n = 45), with or without Alzheimer (AD)-type changes, and compared the apoE genotype with that in healthy age-matched controls (n = 59). The PD cases were divided into two groups according to the CERAD criteria: "O + A", with no or only uncertain histological findings of AD, and "B + C" with histological findings suggestive or indicative of AD. DNA was isolated from frozen brain samples, and the apoE genotypes were determined using polymerase chain reaction amplification and subsequent restriction analysis by HhaI enzyme.
