مقدمه: یکی از مشکلات عمده بیماران دیابتی افزایش قند خون و کاهش ترشح انسولین است که به نوبه خود سبب ایجاد سایر عوارض دیابت می شود. بنابراین به نظر می رسد یافتن ترکیباتی که از بروز دیابت جلوگیری کنند، می تواند مفید باشد. گاما آمینوبوتیریک اسید (گابا) یک میانجی مهاری در سیستم عصبی است. علاوه بر آن گابا، در پاتوفیزیولوژی دیابت نقش دارد. گابا در بافت پانکراس مبتلایان به دیابت کاهش می یابد . این مط...
To know the effects of nicotinamide (NCT) treatment for 5 weeks at the early age on insulitis and development of diabetes in non-obese diabetic (NOD) mice, this experiment was performed. Ten ICR (Institute of Cancer Research) and 15 female NOD mice at 4 weeks of age were used. Mice were assigned to ICR and NOD groups, and NOD mice were randomly divided to control and NCT-treated groups. NCT was...
Human clinical trials in type 1 diabetes (T1D) patients using mesenchymal stem cells (MSC) are presently underway without prior validation in a mouse model for the disease. In response to this void, we characterized bone marrow-derived murine MSC for their ability to modulate immune responses in the context of T1D, as represented in NOD mice. In comparison to NOD mice, BALB/c-MSC mice were foun...
Because few data were available on glucose homeostasis at the early prediabetic stage in the nonobese diabetic (NOD) mouse, we investigated glycemia, insulinemia, and pancreatic insulin content under basal conditions in both sexes of 4-, 6-, and 8-week-old fed NOD mice, compared with sex- and age-matched fed C57BL/6 mice. We also investigated glucose tolerance in both sexes of fasting 8-week-ol...
T cells play an important role in the pathogenesis of diabetes in the nonobese diabetic (NOD) mouse. CD8 cytotoxic T cell lines and clones were generated from the lymphocytic infiltrate in the islets of Langerhans of young (7-wk-old). NOD mice by growing them on (NOD x B6-RIP-B7-1)F1 islets. These cells proliferate specifically to NOD islets and kill NOD islets in vitro. The cells are restricte...
The NOD mouse has been a critical tool in the quest to understand the genetic control of type 1 diabetes (T1D), and over 25 murine insulin-dependent diabetes (Idd) loci that modulate the natural history of T1D have been identified (1). Several of the candidate genes identified in NOD mice also play a role in human T1D, suggesting that dysregulated immune pathways in NOD may closely resemble tho...
Sensitivity of transcritical cycle and turbine design to dopant fraction in CO2-based working fluids
Abstract Supercritical CO2 (sCO2) power cycles have gained prominence for their expected excellent performance and compactness. Among benefits, they may potentially reduce the cost of Concentrated Solar Power (CSP) plants. Because critical temperature is close to ambient temperatures in areas with good solar irradiation, dry cooling penalise efficiency sCO2 CSP Recent research has investigated ...
The NOD mouse spontaneously develops autoimmune diabetes. Dendritic cells (DC) play a crucial role in the autoimmune response. Previous studies have reported a defective DC generation in vitro from the NOD mouse bone marrow (BM), but a deviated development of myeloid precursors into non-DC in response to GM-CSF was not considered. In this study, we demonstrate several abnormalities during myelo...
Nodularin (NOD) is greatly produced by Nodularia spumigena and released into the environment when toxic cyanobacterial blooms happened in natural water body, which is seriously harmful to human and animals. The promising bacterial strain of Sphingopyxis sp. USTB-05 was found to have an ability in biodegrading NOD. Initially, 11.6 mg/L of NOD could be completely eliminated within 72 h by whole c...
We investigated the role of Smad4, a signaling molecule of the TGF-beta pathway, in T cells on the pathology of Sjögren's syndrome (SS) in nonobese diabetic (NOD) mice, an animal model of SS. T cell-specific Smad4-deleted (Smad4fl/fl,CD4-Cre; Smad4 tKO) NOD mice had accelerated development of SS compared with wild-type (Smad4+/+,CD4-Cre; WT) NOD mice, including increased lymphocyte infiltration...
