BACKGROUND Human immunity-related GTPase M (IRGM) is found to play an important role in defense against intracellular pathogen Mycobacterium tuberculosis in vitro by regulating autophagy. To verify whether single nucleotide polymorphisms (SNPs) in the promoter region of IRGM gene are associated with tuberculosis (TB) 1.7 kb IRGM promoter region was(More)
BACKGROUND Tuberculosis (TB) is a serious world-wide health problem, causing millions of deaths every year. Metabolomics is a relatively new approach to identify disease specific biomarkers. However, there is little information available on metabolite biomarkers in TB. In this study, we used gas chromatography/time-of-flight mass spectrometry (GC/TOF-MS) to(More)
Huwentoxin-I (HWTX-I) is a small 33-amino acid neurotoxin from the venom of the Chinese bird spider Ornithoctonus huwena. HWTX-I selectively blocks N-type voltage-sensitive calcium channels (N-VSCCs) and has great potential for clinical application as a novel analgesic without inducing drug tolerance. However, there are still many unsolved issues for this(More)
As the main structural protein of oil body, OLEOSIN is highly expressed only during seed development. OLEOSIN promoter is a very useful tool for seed-specific gene engineering and seed bioreactor designing. The B3 domain transcription factor leafy cotyledon2 (LEC2) plays an important role in regulating seed development and seed-specific gene expression.(More)
BACKGROUND A pathological examination plays an important role in the confirmation of a diagnosis of tuberculosis, especially for smear- and culture-negative cases. However, conventional Ziehl-Neelsen staining and histological tests lack sensitivity and specificity. OBJECTIVE To evaluate the diagnostic value of immunohistochemical staining to detect(More)
Primary pulmonary mucinous adenocarcinoma (PPMA) is one of the important subtypes of lung adenocarcinoma. Detection of anaplastic lymphoma receptor tyrosine kinase (ALK) rearrangements and of KRAS and epidermal growth factor receptor (EGFR) mutations will help in diagnosing and predicting treatment outcome. The aim of this study was to investigate the(More)
Although primary mucin-producing adenocarcinoma of the lung is uncommon, each subtype has distinct clinical, pathological, molecular, and prognostic characteristics. This study aimed to determine correlations between clinical and pathological features and genetic phenotypes with the prognosis. We immunohistochemically examined the protein levels of thyroid(More)
OBJECTIVE To detect the expression of Mycobacterium tuberculosis secreted protein Ag85B in paraffin-embedded tissues by immunohistochemistry (IHC), and to evaluate its application in the pathological diagnosis of tuberculosis. METHODS One hundred and five tuberculosis specimens (54 pulmonary tuberculosis, 51 lymph nodal tuberculosis) and 51 specimens of(More)
Tuberculous pleurisy is one of the most common types of extrapulmonary tuberculosis, but its diagnosis remains difficult. In this study, we report for the first time on the detection of cell-free Mycobacterium tuberculosis DNA in pleural effusion and an evaluation of a newly developed molecular assay for the detection of cell-free Mycobacterium tuberculosis(More)
A GC/TOF-MS was applied to the determination of metabolites in human macrophages. The extraction conditions and quenching conditions were investigated and optimized. The results indicated that 0.9% w/v sodium chloride at 4°C was the most favorable condition to quench macrophage, 1 mL 50% ACN for 2 min in ice bath was the optimal condition to extract 5 ×(More)
