Background: Sphingomyelin (SM) hydrolysis generates biologically active products regulating cell growth, differentiation and apoptosis. Dietary SM has been found to inhibit colonic tumorigenesis. Alkaline sphingomyelinase (alk-SMase) is the key enzyme responsible for sphingomyelin digestion in the gut. Whether or not dietary sphingomyelin affects alk-SMase expression was examined in a colon cancer

We analyzed the presenting features and survival in 1689 patients with multiple myeloma aged younger than 50 years compared with 8860 patients 50 years of age and older. Of the total 10 549 patients, 7765 received conventional therapy and 2784 received high-dose therapy. Young patients were more frequently male, had more favorable features such as low International Staging System (ISS) and Durle-S

Abstract in UndeterminedIn this paper, different multivariate statistical approaches for analysing wastewater treatment process data are presented and compared. For this purpose, all the methods have been tested using one-year operational data in a simulation model benchmark. The general monitoring strategy adopted includes a screening stage to improve data quality, all adaptive model to detect an

The 2nd Helsingborg Consensus Conference on European Stroke Strategies, was held March 2006 with the aims to update core issues in stroke management, to monitor progress, and to set new targets for the year 2015. the congress was organized by the International Society of Internal Medicine, endorsed by the European Stroke Council and the International Stroke Society, and co-sponsored by the WHO Reg

Objective. To investigate whether IgG-degrading enzyme of Streptococcus pyogenes (IdeS), a bacterial cysteine endopeptidase that cleaves human IgG in the hinge region, can be used for blocking the development of arthritis. Methods. Recombinant IdeS was purified and tested for specificity against mouse IgG. IdeS was injected intravenously into mice with collagen antibody-induced arthritis (CAIA), c

Purpose. To explore musculoskeletal findings in patients with cervicogenic dizziness and how these findings relate to pain and dizziness. To study treatment effects and long-term symptom progress. Method. Twenty-two patients ( 20 women, 2 men; mean age 37 years) with suspected cervicogenic dizziness underwent a structured physical examination before and after physiotherapy guided by the musculoske

Background:Approximately 10-20% of stroke cases have normal blood pressure (BP). The objective of this study was to explore whether the risk of ischemic stroke is related to the carotid intima-media thickness (CIMT) and atherosclerotic lesions in a cohort of subjects with normal BP. Methods:Common CIMT and the presence of carotid plaque were determined by B-mode ultrasound in 6,103 subjects, rando

The application of scanning electron microscopy (SEM) and secondary ion mass spectrometry (SIMS) for characterization of mixed plutonium and uranium particles from nuclear weapons material is presented. The particles originated from the so-called Thule accident in Greenland in 1968. Morphological properties have been studied by SEM and two groups were identified: a “popcorn” structure and a spongy

Helicobacter pylori is a major factor for the development of gastric cancer. The aim of this study was to define serum antibody patterns associated with H. pylori infection in patients with gastric cancer using a Western blot technique. Serum samples collected from 115 patients with gastric cancer and 110 age- and gender-matched patients without gastrointestinal diseases were tested for IgG antibo

Little attention has been paid to a possible relationship between lysosomal function and stimulation of secretory processes in endocrine cells. The last few years it has become increasingly evident that the secretion of insulin from the pancreatic beta-cell is the result of a very complex cascade of events, the details of which are far from elucidated and indeed may include the participation of th

Aqueous solutions of lactose and polyethylene glycol (PEG) were spray dried in a Buchi Model 191 spray dryer with the aim to investigate the effect of PEG on the crystallinity of the composite. A PEG concentration of 10.7% by weight of solids was studied for PEG 200, 600, 1500, 4000 and 8000. For PEG 200 and 4000 additional concentrations from 1.5-19.3% to 1.5-32.4%, respectively, were investigate

METHOD AND RESULTS: A standardized histopathological protocol has been designed, in which different histological characteristics of ductal carcinoma in situ (DCIS) are reported: nuclear grade (ng), growth pattern according to Andersen et al., necrosis, size of the lesion, resection margins and focality. Using this protocol a re-evaluation of a population-based consecutive series of 306 cases of DC

This study aimed to determine the effects of advanced glycation end products (AGEs) on endothelial cytoskeleton morphology and permeability, and to detect the underlying signaling mechanisms involved in these responses. Cultured endothelial cells (ECs) were exposed to AGE-modified human serum albumin (AGE-HSA), and EC cytoskeletal changes were evaluated by observing fluorescence of F-actin followi

We have developed automatic methods to calculate multipoles and anisotropic polarizabilities for all atoms and bond centers in a protein and to include such a model in the calculation of electronic properties at any level of quantum mechanical theory. This approach is applied for the calculation of the electronic spectra of retinal in rhodopsin at the CASPT2//CASSCF level (second-order multiconfig
