Recent work found that lower endogenous levels of the gamma-aminobutyric acid-agonist, neuroactive steroid 3alpha-hydroxy-5alpha-pregnan-20-one (3alpha,5alpha-THP) may be correlated with increased ethanol withdrawal severity in the selectively bred Withdrawal Seizure-Prone and -Resistant mice. The present studies were conducted to determine whether decreased sensitivity to 3alpha,5alpha-THP was...

Interleukin-8 (IL-8) or CXCL8 is a potent chemotactic factor that is involved in atherogenesis. IL-8 mediates its pre-inflammatory effects through interaction with CXCR1 and CXCR2. In the present study, we investigated the effects of angiotensin II (Ang II) on IL-8 synthesis and CXCR1/CXCR2 expression of THP-1 monocytes. IL-8 was measured in the culture medium using ELISA. Expression of chemoki...

Cardiovascular diseases are the leading causes of death worldwide, closely followed by cancer. To investigate impact breast cancer cell lines (SKBR3, MCF-7, and MDA-MB-231) on endothelial adhesion, a blended medium containing 30% breast-cancer-conditioned was prepared. This then exposed to human umbilical vein cells (HUVECs) monocytes (THP-1) for 48 h. Homemade oxidized low-density lipoproteins...

background: macrophage immune responses are affected by the secretory proteins of mycobacterium tuberculosis (mtb). this study aimed to examine the immune responses of macrophages to mtb secretory antigens, namely esat-6, cfp-10, and esat-6/cfp-10. methods: thp-1 cells (a human monocytic cell line) were cultured and differentiated to macrophages by phorbol 12-myristate 13-acetate. the cytotoxic...

hepatitis b virus (hbv) dna polymerase transactivated protein 1 (hbvdnaptp1) is a novel protein transactivated by hbv dna polymerase, screened by suppression subtractive hybridization technique (genbank accession no: ay450389). the biological function of hbvdnaptp1 was investigated in this study.we constructed a vector pcdna3.1 (-)/myc-his a-hbvdnaptp1 and used it to transfect acute monocytic l...

BACKGROUND Lipoproteins containing apolipoprotein (apo) CIII predict coronary heart disease and associate with components of the metabolic syndrome. ApoCIII inhibits lipoprotein catabolism in plasma. However, it is unknown whether apoCIII itself, or in association with VLDL, LDL, or HDL, directly affects atherogenic mechanisms in vascular cells. Thus, we investigated the direct effect of lipopr...

A method for direct determination of DL-tetrahydropalmatine (DL-THP) in Corydalis yanhusuo, a traditional Chinese herb, by L-THP imprinted monolithic precolumn on-line/off-line coupling with reversed-phase high performance liquid chromatography (RP-HPLC) was developed. The L-THP imprinted monolithic column has been prepared by in situ polymerization using methacrylic acid (MAA) and ethylene dim...

Tumor-associated macrophages (TAMs) are known to be involved in the progression of various human malignancies. We previously demonstrated that CD204 was a useful marker for TAMs contributing to the angiogenesis, progression, and prognosis of human esophageal squamous cell carcinoma (ESCC). We also showed that conditioned media of ESCC cell lines induced CD204 expression in THP-1 human monocytic...

Immunoglobulin A (IgA) and alveolar macrophages are two important components of the immune system in the respiratory tract. Fc alpha-receptors (Fc alpha R) are present on neutrophils, eosinophils and a series of human mononuclear phagocytes, including monocytes, alveolar macrophages and leukaemia cell lines (U-937). In the present study, using idiotypes and anti-idiotypic antibodies, we report ...

BACKGROUND Cervical proprioception is a common term used in neck rehabilitation, and it is examined using neutral head position (NHP) and target head position (THP) tests. OBJECTIVE To investigate intra- and inter-rater reliability of the NHP and THP tests in patients with neck pain and in healthy controls. METHODS The intra-rater (between-day) and inter-rater (within-day) reliability of th...
