Oligodendrocyte (OL) plays a critical role in myelination and axon maintenance in central nervous system. Recent studies show that OL can also express NMDA receptors in development and pathological situations in white matter. There is still lack of studies about OL properties and function in gray matter of brain. Here we reported that some glial cells in CA1 region of rat hippocampal slices (P1...

Objective Oxidative stress and immune response are associated with acute renal failure (ARF). Ophiocordyceps lanpingensis (OL) might be an antioxidant and immunopotentiator. In this study, we explored the protective effects of OL on glycerol-induced ARF. Methods Male mice were randomly divided into four groups, specifically, glycerol-induced ARF model group, low-dose OL-treated group (1.0 g/k...

Hypoxic-ischemic injury to the periventricular cerebral white matter [periventricular leukomalacia (PVL)] results in cerebral palsy and is the leading cause of brain injury in premature infants. The principal feature of PVL is a chronic disturbance of myelination and suggests that oligodendrocyte (OL) lineage progression is disrupted by ischemic injury. We determined the OL lineage stages at ri...

Six mutants of Cryptococcus neoformans resistant to nystatin and pimaricin and three mutants resistant to amphotericin B were isolated by ultraviolet irradiation techniques from two wild-type strains. The major sterols of the wild-type strains were Delta(7)-ergosten-3beta-ol and ergosterol. All six mutants resistant to nystatin and pimaricin showed either loss of ergosterol and concurrent produ...

BACKGROUND The timely onset of stage II lactogenesis (OL) is important for successful breastfeeding and newborn health. Several risk factors for delayed OL are common in women with a history of gestational diabetes mellitus (GDM), which may affect their chances for successful breastfeeding outcomes. OBJECTIVE We investigated the prevalence and risk factors associated with delayed OL in a raci...

We demonstrate that the motion of dark solitons (DSs) can be controlled by means of periodic potentials. The mechanism is realized in terms of cigar-shaped Bose-Einstein condensates confined in a harmonic magnetic potential, in the presence of an optical lattice (OL). In the case when the OL period is comparable to the width of the DS, we demonstrate that (a) a moving dark soliton can be captur...

This experiment was conducted to investigate the effects of olive leaf (OL) on immune response and some blood metabolites of broiler chickens. A total of 400 one-day-old broiler chicks (male and female) were randomly assigned to 5 experimental treatments with 4 replicates of 20 birds each. Birds of different treatments were given diets containing 0, 0.25, 0.5, 0.75 and 1% OL powder from 14 to 4...

We have investigated the expression of integrins by rat oligodendroglia grown in primary culture and the functional role of these proteins in myelinogenesis. Immunochemical analysis, using antibodies to a number of alpha and beta integrin subunits, revealed that oligodendrocytes express only one detectable integrin receptor complex (alpha OL beta OL). This complex is immunoprecipitated by a pol...
