This study was designed to detect vascular endothelial growth factor (VEGF) and its soluble receptor (sVEGFR-1) in follicular fluid specimens and to evaluate the importance of sVEGFR-1 with respect to ovarian response to gonadotrophin stimulation. A total of 69 patients was treated for IVF with recombinant human follicle stimulating hormone (FSH). Concentrations of VEGF and sVEGFR-1 were quanti...

Granulocyte colony-stimulating factor (G-CSF) can effectively mobilize hematopoietic stem and progenitor cells from bone marrow into blood, thereby allowing peripheral blood stem cells (PBSCs) to be used for transplantation. The efficiency of PBSC mobilization response to G-CSF is a multigene trait. DBA/2 (high-responder) and C57BL/6 (low-responder) mice were used for a genetic analysis of G-CS...

It has previously been demonstrated that gingival fibroblasts derived from nifedipine-reactive patients (nifedipine responders) show a greater cell proliferation rate than those from nifedipine non-reactive patients (nifedipine non-responders) in the presence of 1 microM nifedipine. The aim of the present study was to characterize cell cycle differences between nifedipine responder and non-resp...

The H-2 haplotype of the chimeric host determines the responder phenotype of maturing T cells. Spleen cells of chimeric mice formed when (K(k) nonresponder to D(b) x K(b) responder to D(b) plus vaccinia)F(1) bone marrow cells were used to reconstitute K(b)D(b) (C57BL/6 D(b) responder) irradiated recipients generated high levels of D(b) plus vaccinia virus-specific cytotoxic T cells. The same st...

Numerous studies have provided clues about the ontogeny of lateralization of auditory processing in humans, but most have employed specific subtypes of stimuli and/or have assessed responses in discrete temporal windows. The present study used near-infrared spectroscopy (NIRS) to establish changes in hemodynamic activity in the neocortex of preverbal infants (aged 4-11 months) while they were e...

Intestinal epithelial cells (IECs) are continuously exposed to large numbers of commensal bacteria but are relatively insensitive to them, thereby averting an excessive inflammatory reaction. In this study, we show that the low responsiveness of human IEC lines to LPS was mainly brought about by a down-regulation of TLR4 gene transcription. Additionally, the presence of an IEC-specific represso...
