Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Medicine 1115. 50 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9276-2. Campylobacter jejuni is the leading bacterial cause of gastrointestinal diarrheal disease in humans worldwide. This zoonotic pathogen has a complex e...

The present study aimed at assesssing – by clinical, histological and radiological investigations – the influence of some external factors on the pulp-dentin complex, and at providing a causal interpretation of the structural changes observed. Materials and methods. Clinical and radiological exams were performed on 65 old patients with ages between 60-75, and also on 40 young patients with ages...

Abstract Study question Can CAPA-IVM (Biphasic in-vitro maturation) with C-type natriuretic peptide (CNP), followed by in vitro maturation (IVM) improve ovarian tissue oocyte (OTO) transgender patients? Summary answer Biphasic did not show any significant difference competence and genetic variations when compared in-house IVM. What is known already OTO-IVM a method of fertility preservation pat...

Background: Babesia microti, a tick-borne parasite endemic to the northeast and upper Midwest, is the primary cause of human babesiosis in the United States. Although these infections are usually subclinical or self-limited in immunocompetent people, severe disease can be present in susceptible populations (including the elderly or immunocompromised). Here, infections result in hemolytic anemia...

Heterotrimeric G proteins (composed of a , p and y subunits) mediate extracellular signals by coupling membrane bound receptors to intracellular second messenger systems [ 11. Despite the lack of obvious hydrophobic domains [2], G a subunits are associated with the cytoplasmic face of the membrane. This association has been proposed to be mediated by Py association [3], however studies of Goa, ...

Bioconversion, particularly enzymatic hydrolysis of cellulosic materials to useful products has great potential and is being actively investigated [l-31. Biotechnological utilization of cellulose requires a very efficient cellulolytic enzyme system active on native cellulose. Cellulases are nulticomponent enzyme systems in which the synergistic action of endoglucanase, exoglucanase and Betagluc...

Apolipoprotein B complexed with Triton X-100 (TApoB) has been isolated from human low density lipoprotein (LDL). Preparations are heterogeneous when analyzed by sedimentation velocity, with a major 12 S species and minor 17 S species present. The 12 S T-ApoB complex possesses a molecular weight of 880,000 containing 400,000 daltons of protein. Hydrodynamic measurements on this complex are consi...

INTRODUCTION AND METHODS. Nitric oxide (NO) has recently emerged as a major modulator of carotid body (CB) chemoreception. This is evidenced by functional and morphological studies. Chemosensory activity is inhibited by NO agonists and disinhibited by antagonists in both in situ and in vitro preparations (1, 2). At the light microscopic level, the NADPH-diaphorase (NADPH-d)/nitric oxide synthas...

Phagocytes bear more than one class of receptors for the Fc domain of IgG (FcgammaR). In addition the same ligand can interact with different classes of FcgammaR. This complexity makes it difficult to study the contribution of the various classes of FcgammaR to antimicrobial functions. To circumvent this difficulty, in the present study mouse 3T6 fibroblasts transfected with cDNA encoding for h...

The kinetics of pyruvate reduction by LDH isozymes in the presence of NADH is said to be an ordered bisubstrate reaction characterized by Michaelian concentration dependence (Borgmann et al., 1975). If the reaction is ordered, no cooperativity can occur between the two substrates (NADH and pyruvate) (Neet, 1995). Experiments with fish LDH showed, however, that this enzyme might display two type...
