Long-term beta-adrenergic receptor blockade increases levels of the most mature thymocyte subsets in aged rats
(Elsevier, Amsterdam, 2007)
Age-related increase in the density of thymic noradrenergic fibres and noradrenaline (NA) concentration is proposed to be associated with thymic involution and altered thymopoiesis. To test this hypothesis thymocyte ...
Early postnatal castration affects thymic and thymocyte noradrenaline levels and beta-adrenoceptor-mediated influence on the thymopoiesis in adult rats
(Elsevier, Amsterdam, 2007)
The interactions among the nervous, endocrine and immune system were studied by examining: i) thymic and thymocyte catecholamine levels in adult rats castrated (Cx) at postnatal day 3 and ii) effects of 14-day-long propranolol ...
Beta-adrenoceptor blockade ameliorates the clinical course of experimental allergic encephalomyelitis and diminishes its aggravation in adrenalectomized rats
(Elsevier Science Bv, Amsterdam, 2007)
As glucocorticoids influence both catecholamine synthesis and adrenoceptor expression by immune cells, the current study was undertaken to distinguish their direct effects on the development of experimental allergic ...
Peripubertal orchidectomy transitorily affects age-associated thymic involution in rats
(Assoc Bras Divulg Cientifica, Sao Paulo, 2007)
The role of gonadal hormones in induction and, particularly, maintenance/ progression of rat thymic involution, which normally starts around puberty, was reassessed by examining the effects of peripubertal orchidectomy on ...
Somatostatin modulates T cells development in adult rat thymus
(Elsevier Science Bv, Amsterdam, 2007)
It is well known that somatostatin modulates thymic functions, such as binding to receptors. In order to elucidate the influence of somatostatin on the thymus architecture and the T cells maturation, young adult male rats ...
Changes in thymus size, cellularity and relation between thymocyte subpopulations in young adult rats induced by Somatostatin-14
(Churchill Livingstone, Edinburgh, 2007)
The role of somatostatin on inhibition of both normal and tumor cell cycle, secretion of endocrine and exocrine cells, as well as induction apoptosis is well documented. However, its effect on T cell development and thymic ...
A matrix effect in pectin-rich fruits hampers digestion of allergen by pepsin in vivo and in vitro
(Clinical and Experimental Allergy, 2007)
Background: It is a general belief that a food allergen should be stable to gastric digestion. Various acidic plant polysaccharides, including pectin, are ubiquitous in fruit matrixes and can form hydrogels under low-pH ...
Intraoperative anaphylactic shock in a child with undiagnosed latex allergy
(Blackwell Publishing, Oxford, 2007)
Exposure to acute physical and psychological stress alters the response of rat macrophages to corticosterone, neuropeptide Y and beta-endorphin
(Taylor & Francis Ltd, Abingdon, 2007)
The objective of the present study was to investigate the effect of acute exposure to electric tail shock stress (ES) and a stress witnessing procedure ( SW), as models for physical and psychological stress paradigms, ...
Quantification of Art v 1 and Act c 1 being major allergens of mugwort pollen and kiwi fruit extracts in mass-units by ion-exchange HPLC-UV method
(Elsevier Science Bv, Amsterdam, 2007)
A simple ion-exchange HPLC-UV method was developed for determination of major allergens from mugwort pollen and kiwi fruit extracts in mass-units. The separation of Art v 1 and Act c 1 from other components in the extracts ...
