abstract: introduction & objective: the infertility treatment by using in vitro matured oocyte has many potential applications. it minimizes the risk of ovarian hyper stimulation and is an alternative treatment for women with polycystic ovarian syndrome who may have problems regarding stimulation for ivf. this method may prove important for subjects in need of fertility preservation and also pr...

background worldwide, the incidence of inflammatory bowel disease (ibd) is increasing. this study aims to evaluate the diagnostic value of two serological markers, atypical perinuclear anti-neutrophil cytoplasmic antibodies (atypical-p-anca) and anti-saccharomyces cerevisiae antibodies (asca), with the intent to determinetheir relationship to ulcerative colitis (uc) and crohn's disease (cd), in...

Fertilization process of Paramecium caudatum includes a reciprocal exchange of migratory pronuclei across a temporary junction between conjugating cells. To know the role of microtubules on the behavior of pronuclei during conjugation in P. caudatum, the localization of microtubules was investigated by indirect immunofluorescence with a monoclonal anti-a-tubulin antibody. The immunofluorescence...

We have used membrane surface charge to modulate the structural dynamics of an integral membrane protein, phospholamban (PLB), and thereby its functional inhibition of the sarcoplasmic reticulum Ca-ATPase (SERCA). It was previously shown by electron paramagnetic resonance, in vesicles of neutral lipids, that the PLB cytoplasmic domain is in equilibrium between an ordered T state and a dynamical...

Quantitative microscopical measurements have been made of the proportion of cell volume occupied by cytoplasm in a cell suspension culture derived from cotyledons of bush bean (cv. Contender). On a 7-day culture cycle, the content of cytoplasm varies from 25% at the time of transfer to 45% at the start of the phase of rapid cell division. If the culture is continued beyond 7 days, the vacuole v...

Human metapneumovirus (HMPV) is a recently discovered paramyxovirus of the subfamily Pneumovirinae, which also includes avian pneumovirus and human respiratory syncytial virus (HRSV). HMPV is an important cause of respiratory disease worldwide. To understand early events in HMPV replication, cDNAs encoding the HMPV nucleoprotein (N), phosphoprotein (P), matrix protein (M), M2-1 protein and M2-2...

T antigen was localized in simian virus 40 lytically infected and transformed cells by Fab' antibody conjugates at the ultrastructural level. This virus-specific protein appeared in the cytoplasm of permissive cells as early as 3 h after infection. At later time intervals, the T antigen was localized in both the cytoplasm and nucleus and finally (24 h) in the nucleus. These results suggest a sy...

Antineutrophil cytoplasmic autoantibodies (ANCA) were detected in patients with autoimmune and vascular diseases such as Wegener's granulomatosis, polyarteritis nodosa and systemic lupus erythematosus. Indirect immunofluorescence (IIF) technique was employed to detect these autoantibodies. By this method, two general patterns of ANCA were seen: a cytoplasmic (cANCA) and a perinuclear form ...

Nazarewicz RR, Dikalova AE, Bikineyeva A, Dikalov SI. Nox2 as a potential target of mitochondrial superoxide and its role in endothelial oxidative stress. Am J Physiol Heart Circ Physiol 305: H1131–H1140, 2013. First published August 16, 2013; doi:10.1152/ajpheart.00063.2013.—Superoxide (O2 ) production by the NADPH oxidases is implicated in the pathogenesis of many cardiovascular diseases, inc...

This report describes initial efforts to map the ankyrin-binding site of the cytoplasmic domain of the human erythrocyte anion exchanger. The conclusions are that this site is likely to involve a fairly extended sequence in the midregion of the cytoplasmic domain and requires interactions that are not provided by isolated peptides. The region of the sequence involving residues 174-186 is likely...
