BACKGROUND Treatments about small hepatocellular carcinoma (HCC) and hypersplenism associated with good hepatic reserve are not well established. The aim of this study was to investigate the outcome of synchronous hepatectomy and splenectomy for those patients. STUDY DESIGN Splenomegaly and hypersplenism were defined as a pathological spleen. Seven hundred fifty-six patients with small HCC (3...

A 1,000-fold difference has been reported in dioxin sensitivity between avian species. This difference is because the 2 amino acids in the type 1 aryl hydrocarbon receptor (AhR1), at positions 325 and 381, correspond to Leu324 and Ser380 in chickens. The chicken had been reported to be the only avian species to possess a sensitive form of AhR1. This is the first study to reveal that the ostrich...

Porphyromonas gingivalis is a major contributor to the pathogenesis of periodontitis, an infection-driven inflammatory disease that leads to bone destruction. This pathogen stimulates pro-interleukin (IL)-1β synthesis but not mature IL-1β secretion, unless the P2X7 receptor is activated by extracellular ATP (eATP). Here, we investigated the role of P. gingivalis fimbriae in eATP-induced IL-1β r...

Gender preferences may have substantial implications for a couple’s fertility behavior. However, there is only limited empirical research investigating this subject in modern Western societies. In this paper, data from the Fertility and Family Surveys are used to compare 17 European countries with respect to their gender preferences for children. Despite substantial regional heterogeneity acros...

Epoxide hydrolases (EH) catalyze the hydrolysis of epoxides and arene oxides to their corresponding diols. The crystal structure of murine soluble EH suggests that Tyr(465) and Tyr(381) act as acid catalysts, activating the epoxide ring and facilitating the formation of a covalent intermediate between the epoxide and the enzyme. To explore the role of these two residues, mutant enzymes were pro...

MSK1 (mitogen- and stress-activated protein kinase) is a kinase activated in cells downstream of both the ERK1/2 (extracellular-signal-regulated kinase) and p38 MAPK (mitogen-activated protein kinase) cascades. In the present study, we show that, in addition to being phosphorylated on Thr-581 and Ser-360 by ERK1/2 or p38, MSK1 can autophosphorylate on at least six sites: Ser-212, Ser-376, Ser-3...

Bacteroides spp. may contribute to the chronicity of mixed infections by affecting the normal functions of polymorphonuclear leukocytes (PMN). This study evaluated the physiologic and biochemical responses of human peripheral blood PMN to a variety of strains of the oral periodontal pathogen Porphyromonas (Bacteroides) gingivalis. Strain 381 and ATCC type strain 33277 caused rapid and lasting d...

Porphyromonas gingivalis 381 fimbriae, their synthetic peptide segments, and lipopolysaccharide (LPS) were examined for hemagglutinating and migration-stimulating activities. P. gingivalis 381 fimbriae clearly caused hemagglutination, and several oligopeptide segments such as FP381(61-80), FP381(171-185), and FP381(302-321), corresponding to the amino acid residue numbers based on the amino aci...

OBJECTIVES Tibialis posterior tendon transfer (TPT) technique, using either the Circum-tibial (CT) or Inter-osseus (IO) route is the standard surgical technique to correct foot drop. The selection of the route of transfer is usually dependent on the surgeon's preference. This study aims to identify criteria to help make that selection. SUBJECTS AND METHODS A study was carried out on 381 feet ...
