Changes in the basement membrane zone components during skeletal muscle fiber degeneration and regeneration.

Ní féidir ach le húsáideoirí cláraithe ailt a aistriú

Logáil Isteach / Cláraigh

The basement membrane of skeletal muscle fibers is believed to persist unchanged during myofiber degeneration and act as a tubular structure within which the regeneration of new myofibers occurs. In the present study we describe macromolecular changes in the basement membrane zone during muscle

Concanavalin A protects hair cells against gentamicin ototoxicity in rat cochlear explant cultures.

Degeneration of hair cells and spiral ganglion neurons due to acoustic trauma and various ototoxins is a major cause of hearing loss. Although our previous study demonstrates that specific neurotrophins protect spiral ganglion neurons from ototoxic insult, they do not protect hair cells. In the

Evaluation of immunoregulatory cells in Duchenne muscular dystrophy and spinal muscular atrophy among African and Indian patients.

Suppressor cells were assayed by numerical and functional tests in Duchenne muscular dystrophy (DMD) and spinal muscular atrophy (SMA) among African and Indian children in order to contribute to an understanding of the pathogenesis of these neurological disorders. Peripheral blood mononuclears (PBM)

Astilbin prevents concanavalin A-induced liver injury by reducing TNF-alpha production and T lymphocytes adhesion.

The aim of this study was to evaluate the effect of astilbin on concanavalin A (Con A)-induced hepatitis, a T cell-dependent model of liver injury. Con A administration resulted in a severe liver injury in mice, with a strong increment in spleen cell adhesion and liver infiltration of T cells, as

Penetration and uptake of colloidal gold-labeled concanavalin A in the junctional epithelium of the rat.

Logáil Isteach / Cláraigh

A complex of colloidal gold and concanavalin A (CG-Con A) with various biological properties and high ultrastructural resolution was applied into the sulcus of rat molar gingiva and traced with an electron microscope for three hours to examine the cytological changes occurring in the cells of the

Induction of thymocyte apoptosis by systemic administration of concanavalin A in mice: role of TNF-alpha, IFN-gamma and glucocorticoids.

Logáil Isteach / Cláraigh

Administration of concanavalin A (Con A) is a well-established model of acute immune-mediated hepatitis. Here, we demonstrate that intravenous injection of Con A in mice induces profound thymic atrophy. Compared to liver damage, the kinetics of Con A-induced thymic atrophy is slower and more

Fumigaclavine C improves concanavalin A-induced liver injury in mice mainly via inhibiting TNF-alpha production and lymphocyte adhesion to extracellular matrices.

Fumigaclavine C, an alkaloidal metabolite, was produced by Aspergillus fumigatus (strain No. CY018). This study examined the effect of this compound on concanavalin A (Con A)-induced liver injury in mice, a T cell-dependent model of liver damage. Con A administration resulted in severe liver injury,

Recovery of age-dependent immunological deterioration in Balb/c mice by short-term treatment with L-thyroxine.

Logáil Isteach / Cláraigh

The progressive decline of immune efficiency with advancing age has been investigated in Balb/c mice by measuring the spleen-cell responsiveness to both T- and B-mitogens and the capacity to form plaques after immunization with sheep erythrocytes. While the responsiveness to concanavalin A and

Effects of concanavalin A on developing ganglion cells in the retina of chick embryos.

Logáil Isteach / Cláraigh

The administration of concanavalin A (Con A) (50-200 microgram/egg) to chick embryos between the third and the seventh day of incubation has the following effects on the retina: (1) Con A causes the degeneration of a large number of ganglion cells and consequently the layer that should be formed by

Lectins can reverse the distal intestinal atrophy associated with elemental diets in mice.

Ní féidir ach le húsáideoirí cláraithe ailt a aistriú

Logáil Isteach / Cláraigh

BACKGROUND Elemental diets cause intestinal atrophy and reduced intestinal integrity, which can lead to significant increases in intestinal permeability and bacterial translocation. Recently, several lectins have been shown to have trophic effects on the intestine. OBJECTIVE We examined the effects

Partial purification from mammalian peripheral nerve of a trophic factor that ameliorates atrophy of denervated muscle.

Ní féidir ach le húsáideoirí cláraithe ailt a aistriú

Logáil Isteach / Cláraigh

Atrophy in a denervated muscle results from the disuse caused by paralysis of the muscle, and from the loss of special nerve-derived trophic substances. Crude preparations of protein from rat or sheep sciatic nerves have been shown to prevent the nondisuse atrophy of the rat's extensor digitorum

Expression of inducible nitric oxide synthase in the liver is under the control of nuclear factor kappa B in concanavalin A-induced hepatitis.

Logáil Isteach / Cláraigh

OBJECTIVE Both nuclear factor kappa B (NF-kappaB) activation and inducible nitric oxide synthase (iNOS) expression increase in the liver injury, and there are NF-kappaB binding sites in the iNOS promoter. The aim of this study was to investigate the correlation between iNOS expression and NF-kappaB

Beta-amyloid induces local neurite degeneration in cultured hippocampal neurons: evidence for neuritic apoptosis.

Logáil Isteach / Cláraigh

Many apoptotic insults, including beta-amyloid, cause neuritic degeneration. The possibility that apoptotic insults act directly on neurites was investigated in experiments using compartmented cultures of hippocampal neurons. Neurites in modified Campenot chambers displayed morphological signs of

Fibrinoid degeneration and increased vascular permeability induced by renal lysosomal contents. An electron microscopic study on coronary and cerebral arteries of rats.
