Three-dimensional point sets can be used to represent data in different domains. Given a database of 3D point sets, pattern discovery looks for similar subsets that occur in multiple point sets. Geometric hashing proved to be an effective technique in discovering patterns in 3D point sets. However, there are also known shortcomings. We propose a new indexing technique called B Trees. It is an e...

Some hepatocellular adenoma (HCA) subtypes are characterized by different CTNNB1 mutations, leading to beta-catenin activation levels, hence variable immunostaining patterns of glutamine synthetase (GS) expression, and risks malignant transformation. In a retrospective multicentric study 63 resected inflammatory (n=33) noninflammatory (n=30) molecularly confirmed CTNNB1-mutated b-(I)HCA, we inv...

  Abstract   Background: obesity is directly related to dyslipidemia which contributes significantly   to the risk of coronary heart disease, a major cardiovascular disease and a serious   health problem. The aim of this study was to compare the effects of low calorie   diet and those of lovastatin on serum lipoproteins, apo B, homocysteine, and total antioxidant capacity (TAC) in hyperlipidemi...

Human severe combined immunodeficiency (SCID) patients were analyzed by a polymerase chain reaction assay for their recombination capability at the DHQ52-JH region of the immunoglobulin heavy chain locus. Five patients with B cells (B+ SCID) exhibited a recombination pattern also observed in healthy persons. In contrast, six patients lacking B cells (B- SCID) showed a grossly altered rearrangem...

there are currently ‎many different protocols in use for controlled ovarian hyperstimulation (coh), but the optimal method has ‎not yet been determined. to compare the outcome of coh using ‎clomiphene citrate (cc) versus cc plus human menopausal gonadotropin (hmg) in conjunction with intrauterine insemination (iui), we studied 117 infertile couples‎. iui with cc was used in 92 cycles ‎(group a)...

BACKGROUND Toll-like receptors (TLRs) are pattern recognition receptors that recognize pathogen associated molecular patterns and trigger innate immunity leading to initiation of adaptive immunity. TLR-mediated activation of dendritic cells (DCs) is known to be a critical event in the initiation of cellular and humoral immune responses. Recent work however suggests that B cells also express TLR...

Pattern adaptation is very important for visual function, while the mechanisms that mediate pattern adaptation, especially in the dorsal lateral geniculate nucleus (LGNd), are still unclear. Iontophoresis of the antagonists and agonists of GABA receptors were employed to separately investigate the contribution of GABA(A) and GABA(B) receptors to pattern adaptation of LGNd cells. When GABA(A) re...

BACKGROUND This study was conducted to identify dietary patterns and evaluated their association with biochemical blood profiles and body weight among adults with type 2 diabetes mellitus. METHODS This was a cross sectional study conducted among 400 patients with type 2 diabetes mellitus in Tehran from March to August 2013. Biochemical blood profiles, socio-demographic, lifestyle, anthropomet...

This cross-sectional study examined dietary patterns, and the associations of these patterns with demographics, lifestyle, anthropometry and blood pressure in 3707 Chinese people aged 65 years and above taking part in a population-based cohort study investigating the risk factors for osteoporosis. Baseline dietary data were collected using a validated FFQ. Dietary patterns were identified using...
