A total of 7194 faecal samples collected over a 1-year period from patients presenting with diarrhoea were screened for Campylobacter spp. using EntericBios, a multiplex-PCR system. Of 349 Campylobacter-positive samples, 23.8% were shown to be Campylobacter ureolyticus, using a combination of 16S rRNA gene analysis and highly specific primers targeting the HSP60 gene of this organism. This is, to the best of our knowledge, the first report of C. ureolyticus in the faeces of patients presenting with gastroenteritis and may suggest a role for this organism as an emerging enteric pathogen.
Cd151 Reinforces Vascular Stability By Balancing Endothelial Cell Adhesion And Cytoskeletal Tension, Feng Zhang
Cd151 Reinforces Vascular Stability By Balancing Endothelial Cell Adhesion And Cytoskeletal Tension, Feng Zhang
Theses and Dissertations (ETD)
Tetraspanin CD151 is highly expressed in endothelial cells and regulates pathological angiogenesis. However, the mechanism by which CD151 promotes vascular morphogenesis and whether CD151 engages other vascular functions are unclear. We observed that CD151 is required for the maintenance of endothelial capillary-like structures formed in vitro and the integrity of lung endothelial cell-cell contacts in vivo. As a master regulator of endothelial cell-matrix and cell-cell adhesions, CD151 is needed for the optimal functions of various cell adhesion proteins such as integrin, cadherin, and CD44. The loss of CD151 elevates the cellular intrinsic contraction by upregulating RhoA signaling and downregulating of …
Harnessing The Effect Of Adoptively Transferred Tumor-Reactive T Cells On Endogenous (Host-Derived) Antitumor Immunity, Yolanda Nesbeth, Jose R. Conejo-Garcia

Adoptive T cell transfer therapy, the ex vivo activation, expansion, and subsequent administration of tumor-reactive T cells, is already the most effective therapy against certain types of cancer. However, recent evidence in animal models and clinical trials suggests that host conditioning interventions tailored for some of the most aggressive and frequent epithelial cancers will be needed to maximize the benefit of this approach. Similarly, the subsets, stage of differentiation, and ex vivo expansion procedure of tumor-reactive T cells to be adoptively transferred influence their in vivo effectiveness and may need to be adapted for different types of cancer and host …
The Efficacy And Safety Of Insulin-Sensitizing Drugs In Hiv-Associated Lipodystrophy Syndrome: A Meta-Analysis Of Randomized Trials, Siddharth H. Sheth, Robin J. Larson
The Efficacy And Safety Of Insulin-Sensitizing Drugs In Hiv-Associated Lipodystrophy Syndrome: A Meta-Analysis Of Randomized Trials, Siddharth H. Sheth, Robin J. Larson

HIV-associated lipodystrophy syndrome (HALS) is characterized by insulin resistance, abnormal lipid metabolism and redistribution of body fat. To date, there has been no quantitative summary of the effects of insulin sensitizing-agents for the treatment of this challenging problem. We searched MEDLINE, the Cochrane Library, clinical trial registries, conference proceedings and references for randomized trials evaluating rosiglitazone, pioglitazone or metformin in patients with evidence of HALS (last update December 2009). Two reviewers independently abstracted data and assessed quality using a standard form. We contacted authors for missing data and calculated weighted mean differences (WMD) and 95% confidence intervals (CI) for each …
