BACKGROUND Temporary pacemakers (TP) are used in emergency situations for severe bradyarrhythmias secondary to acute myocardial infarction (AMI) and to non-AMI related cardiac disorders. TP have been studied previously in AMI patients treated with thrombolytic therapy; limited information is available on current outcomes in AMI patients treated with percutaneous coronary intervention. METHODS...

The human immunodeficiency virus (HIV-1) causes various hematopoietic abnormalities, with thrombocytopenia (TP) occurring in 30% of infected individuals. In the present study, we aimed to determine whether HIV-1 in the bone marrow of TP patients can infect primary megakaryocytes in vitro, which may contribute to the development of thrombocytopenia. We amplified the V3 loop of HIV-1 envelope fro...

The enzyme/cytokine thymidine phosphorylase/platelet-derived endothelial cell growth factor (TP/PD-ECGF) has diverse functions within cells, including the regulation of steady-state thymidine levels, the conversion of cancer chemotherapeutic agent 5-fluorouracil to an active metabolite, and the mediation of angiogenesis in normal and malignant cells. Although the level of TP/PD-ECGF expression ...

In this report, we describe a new method to measure intracellular zidovudine triphosphate (ZDV-TP) levels in peripheral blood mononuclear cells (PBMCs) from patients treated with ZDV by utilizing inhibition of human immunodeficiency virus type 1 reverse transcriptase activity by ZDV-TP. Intracellular levels of ZDV-TP were determined with our enzymatic assay in PBMCs isolated from the blood of h...

Thymidine phosphorylase (TP) promotes angiogenesis and metastasis, and confers resistance to anticancer agents in some cancer cell types. We previously reported that TP stimulates the expression of interleukin (IL)-8 in human KB cancer cells by an unknown mechanism. A mutation in the nuclear factor (NF)κB binding site of the IL-8 promoter suppressed promoter activity in KB/TP cells that overexp...

Nitroxide small molecule agents are in development as preventative or therapeutic pharmaceutical drugs for age-related macular degeneration (AMD) and cardiovascular disease, which are two major diseases of aging. These aging diseases are associated with patient genetics, smoking, diet, oxidative stress, and chronic inflammation. Nitroxide drugs preventing aging-, smoking-, high sugar or high fa...

BACKGROUND Gastric venous congestion and bleeding in association with total pancreatectomy (TP) were evaluated. METHODS Thirty-eight patients of TP were retrospectively analyzed. TP was classified as TP with distal gastrectomy (TPDG), pylorus-preserving TP (PPTP), subtotal stomach-preserving TP (SSPTP), and TP with segmental duodenectomy (TPSD). RESULTS Portal vein or superior mesenteric ve...

The study was designed to investigate the immune-modulatory effects of triptolide (TP) on CD4(+) T cell responses during liver injury. Previous studies have suggested that TP plays a critical role in modulating both innate and adaptive immune reactions, but its effects on the Th17/Treg balance during TP-induced liver injury remain unknown. In this study, female C57BL/6 mice were administered by...
