As a member of the indigenous gut mucosal microbiota, segmented filamentous bacteria (SFB) colonize the guts of a variety of vertebrates and invertebrates. They are potent microbial stimuli of the gut mucosal immune system. In the small intestines of mice and rats, it has been observed that SFB are absent during the suckling period and appear in high numbers shortly after weaning, then quickly ...
PURPOSE Immunodeficient mice serve as critical hosts for transplantation of xenogeneic cells for in vivo analysis of various biological processes. Because investigators typically select one or two immunodeficient mouse strains as recipients, no comprehensive study has been published documenting differences in human tumor engraftment. Taking advantage of the increased metastatic potential of Rho...
objective: to translate the structured clinical interview for dsm-iv axisi disorders (scid-i) into persian (farsi) and to adapt this instrument for the iranian culture. method: the scid was translated into persian using an elaborate procedure to achieve a satisfactory cross-cultural equivalent. this included forward translation by bilingual (english/persian) translators, discussion and revision...
This paper proposes a downlink synchronization and cell identity (CID) estimation technique for cellular systems based on orthogonal time-frequency space (OTFS). In the proposed technique, each base station (BS) transmits one detection preamble (DP) two OTFS symbols (pilot secondary-CID (SCID) signal (SS)). The DP linear frequency-modulated (LFM) waveform, called proposed-LFM (pLFM), carries pr...
We have generated immunodeficient scid-/scid- (SCID)-transgenic mice expressing the genes for human interleukin 3, granulocyte/macrophage-colony stimulating factor, and stem cell factor. We have compared engraftment and differentiation of human hematopoietic cells in transgenic SCID mice with two strains of nontransgenic SCID mice. Human bone marrow cells carrying the CD34 antigen or human umbi...
BACKGROUND For women facing gonadotoxic treatment, cryopreservation of ovarian tissue with subsequent retransplantation during remission is a promising technique for fertility preservation. However, follicle loss within grafted ovarian tissue can be caused by ischemia and progressive revascularization. Several xenograft models using different immunodeficient rodent lines are suitable for studyi...
We reasoned that the SCID-hu mouse could provide an appropriate lymphoid or stromal microenvironment to support the growth of primary human lymphoma. Heterotransplantation of nine cases of primary T-cell non-Hodgkin's lymphoma (NHL) into untreated SCID mice and SCID mice reconstituted with human fetal thymus, spleen, and liver (SCID-hu) resulted in the development of lymphoid tumors in five (56...
In severe combined immunodeficient (scid) mice, V(D)J recombination is severely impaired due to a recessive mutation ( scid ). Thus, we were surprised to find in this study that V l 1–J l 1 rearrangement is routinely detectable in scid fetal liver, adult bone marrow, and spleen in the apparent absence of completed VH–DJH and V k –J k rearrangements. Particularly surprising, we found the level o...
Mice homozygous for the mutation scid (scid mice) are severely immunodeficient and generally lack detectable numbers of pre-B, B, and T cells. This condition is believed to result from a defect in the mechanism responsible for rearrangement of immunoglobulin and T-cell receptor genes in developing B and T lymphocytes. To test this hypothesis and evaluate whether scid affects only the process of...
We have used homozygous albumin enhancer/promoter-driven urokinase-type plasminogen activator/severe combined immunodeficient (uPA/SCID) mice as hosts for chimeric mice with humanized livers. However, uPA/SCID mice show four disadvantages: the human hepatocytes (h-heps) replacement index in mouse liver is decreased due to deletion of uPA transgene by homologous recombination, kidney disorders a...
