Although it has been recognized that ectopic follicle-like B cell aggregate formation is common in the lungs of patients with tuberculosis, the role of infiltrated B cells in human tuberculosis remains to be elucidated. In the present study, we showed that ectopic B cell aggregate formation was associated with containment of Mycobacterium tuberculosis. The(More)
RATIONALE Although it is well recognized that CD4(+) T cells and T helper (Th) 1 cytokines are critical in the cell-mediated response to Mycobacterium tuberculosis, it is also clear that this immunity alone is not enough. Understanding the roles of other T cell subsets and cytokines is essential for vaccine design and clinical immunotherapy against(More)
Induction of cell apoptosis is one of the major host defense mechanisms through which macrophages control Mycobacterium tuberculosis (Mtb) infection. However, the mechanisms underlying macrophage apoptosis triggered by Mtb infection are still largely unknown. In this study, a microarray profiling survey revealed 14 miRNAs were down-regulated in CD14+(More)
Gamma interferon (IFN-gamma) release assays have been proven to be useful in the diagnosis of Mycobacterium tuberculosis infection. Nevertheless, their specificity and sensitivity vary among the different populations studied. Here, we evaluate the value of an in-house IFN-gamma enzyme-linked immunospot (ELISPOT) assay in the diagnosis of active tuberculosis(More)
In the current study, we assessed and evaluated the costs and benefits of three popular methods of general anesthesia practiced in our department for gynecological laparoscopic surgery in recent years. Sixty adult female patients who underwent elective gynecological laparoscopic surgery under general anesthesia were randomly divided into three groups: group(More)
CD4+ T cells mediate protection against Mycobacterium tuberculosis (Mtb); however, the phenotype of protective T cells is undefined, thereby confounding vaccination efforts. IL-27 is highly expressed during human tuberculosis (TB), and absence of IL-27R (Il27ra) specifically on T cells results in increased protection. IL-27R deficiency during chronic Mtb(More)
OBJECTIVE To investigate the cardioprotective effect of the continuous administration of dexmedetomidine using serum cardiac troponin I (cTnI) and creatine kinase MB (CK-MB) concentrations as biomarkers during off-pump coronary artery bypass grafting (OPCAB) surgery. DESIGN A prospective, randomized, parallel-group controlled study. SETTING A university(More)

BACKGROUND Variations in the hepatitis B virus (HBV) genome may develop spontaneously or under selective pressure from antiviral therapy. Such variations may confer drug resistance or affect virus replication capacity, resulting in failure of antiviral therapy. METHODS A duplex PCR was used to amplify the region of the reverse transcriptase gene, the(More)
Tuberculosis is a global infectious disease caused by Mycobacterium tuberculosis (Mtb). Although novel Mtb biomarkers from both the pathogen and host have been studied, more breakthroughs are still needed to meet different clinic requirements. In an effort to identify Mtb antigens, chaperone-peptide complexes were purified from TB infected lungs using(More)
