Cimetidine-induced vascular cell apoptosis impairs testicular microvasculature in adult rats
(F Hernandez, 2012-10-01)
Cimetidine, an H-2 receptor antagonist used for treatment of gastric ulcers, exerts antiandrogenic and antiangiogenic effects. In the testes cimetidine impairs spermatogenesis, Sertoli cells and peritubular tissue, inducing ...
Mesenchymal stem cells instruct oligodendrogenic fate decision on adult neural stem cells
(ALPHAMED PRESS, 2006-10)
Adult stem cells reside in different tissues and organs of the adult organism. Among these cells are MSCs that are located in the adult bone marrow and NSCs that exist in the adult central nervous system (CNS). In ...
Comparative experimental infection of Lacazia loboi in BALB/c and B10.A mice
(2003-06-01)
Both hind foot pads of BALB/c and B10.A mice strains, were inoculated with a fungal suspension of Lacazia loboi obtained from a Jorge Lobo's disease patient. The suspension had 9 × 105 cells/ml and its viability index was ...

Immunohistochemical characterization of mononuclear cells in delayed hypersensitivity reactions to Paracoccidiodes brasiliensis (paracoccidioidin test)
(Kluwer Academic Publ, 1993-10-01)
The density and distribution of T cells, T helper cells, macrophages and B cells at the site of skin tests with a cytoplasmic Paracoccidioides brasiliensis antigen (paracoccidioidin) was studied at 24 and 48 h post-challenge ...
Unconventional pro-inflammatory CD4+ T cell response in B cell-deficient mice infected with Trypanosoma cruzi
(Frontiers Research Foundation, 2017-11-21)
Chagas disease, caused by the parasite Trypanosoma cruzi, is endemic in Latin America but has become a global public health concern by migration of infected people. It has been reported that parasite persistence as well ...
Understanding the influence of substrate when growing tumorspheres
(BioMed Central, 2021-12)
Background: Cancer stem cells are important for the development of many solid tumors. These cells receive promoting and inhibitory signals that depend on the nature of their environment (their niche) and determine cell ...
