6-Mercaptopurine attenuates tumor necrosis factor-α production in microglia through Nur77-mediated transrepression and PI3K/Akt/mTOR signaling-mediated translational regulation

Physical interaction between Nur77 and p65. BV-2 cells were pretreated with 6-MP (50 μM) for 16 h followed by exposure to LPS (100 ng/ml) for 60 min. Nuclear extracts were harvested for immunoprecipitation (IP) experiments using anti-Nur77 and anti-p65 antibodies. Immunoblot (IB) analyses of the immunoprecipitates were performed using these antibodies. The immunoblots are representative of three independent experiments. (TIF 280 kb

Growth Hormone Deficiency in a Case of Crouzon Syndrome with Hydrocephalus

Crouzon syndrome is one of the most common craniofacial syndromes and is inherited as autosomal dominant with variable expression. We report an 11 and a half-year-old boy with Crouzon syndrome with severe growth retardation. He had hydrocephalus since infancy and recently suffered from frequent dizziness. His bone age was only 5 years according to the Greulich and Pyle atlas. Magnetic resonance imaging showed shallow orbits, obstructive hydrocephalus, and cerebellar tonsil herniation. Growth hormone provocative tests revealed a reduced peak growth hormone response in both insulin and clonidine tests. Severe iron deficiency anemia was noted at the same time. Molecular analysis identified a common mutation point of Cys278Phe for Crouzon syndrome in exon IIIa of the fibroblast growth factor receptor 2 (FGFR2) gene. Since growth retardation is not a common feature of Crouzon syndrome, we reviewed the literature for the incidence of hydrocephalus in Crouzon syndrome and the association with growth hormone deficiency

Metabolic risk factors, exercise capacity and inflammation in postmenopausal women

Session presented on: Tuesday, July 23, 2013: Purpose: The purposes of this study were to investigate metabolic risks factors, exercise capacity, and inflammation state in postmenopausal women; and to evaluate the effect of a supervised aerobic exercise training program on these characteristics. Methods: This study was a prospective, randomized control trail. Forty-six postmenopausal women completed the study: 23 in the exercise, 23 in the control groups. Subjects in the exercise group participated in 30 minutes of moderate-intensity treadmill exercise (60% to 70% of their maximal heart rate performed from exercise testing), three times each week for 12 weeks. Data on metabolic components (blood pressure, blood lipid profile, fasting blood sugar, and waist circumference), serum IL-6 levels, and exercise capacity were analyzed at baseline and the 12th weeks. The metabolic syndrome (MS) score was calculated as the sum of the metabolic components present in each subject. The Generalized Estimating Equation was used to analyze the change in study variables between the two groups. Results: After controlling for age and body mass index, the intervention effect on MS score and exercise capacity in the exercise group were significantly more than the control group at the end of the 12th weeks (Z= 2.72, p \u3c 0.05 and Z = 3.93, p \u3c 0.001 respectively). Significant declines in the level of serum IL-6 was also observed in the exercise group compared with their counterparts on completion of the study (p \u3c0.05). Conclusion: Regular exercise can play a role of improving exercise capacity and metabolic risk factors in postmenopausal women. The result would help to facilitate the application of physical exercise in women health

(Z)-4-(2-Hy­droxy­benzyl­idene)-1-methyl-2-phenyl-1H-imidazol-5(4H)-one

In the title compound, C17H14N2O2, the asymmetric unit comprises two mol­ecules that are comformationally similar [the dihedral angles between the phenyl rings in each are 46.35 (2) and 48.04 (3)°], with the conformation stabilized by intra­molecular O—H⋯N hydrogen bonds, which generate S(7) rings. In the crystal, inversion-related mol­ecules are linked by pairs of weak C—H⋯O hydrogen bonds, forming dimers with an R 2 2(16) graph-set motif. Weak inter-ring π–π stacking is observed in the structure, the shortest centroid-to-centroid distance being 3.7480 (13) Å

(E)-4-[(4-Diethyl­amino-2-hy­droxy­benzyl­idene)amino]­benzonitrile

The title compound, C18H19N3O, displays an E conformation with respect to the C=N double bond. The dihedral angle between the mean planes of the two benzene rings is 24.49 (3)°. An intra­molecular O—H⋯N hydrogen bond generates an S(6) ring. In the crystal, mol­ecules are linked by nonclassical inter­molecular C—H⋯O hydrogen bonds to form an infinite one-dimensional chain along [010], generating a C(8) motif

Panax notoginseng Attenuates Bleomycin-Induced Pulmonary Fibrosis in Mice

Panax notoginseng (PN) is a traditional Chinese herb experimentally proven to have anti-inflammatory effects, and it is used clinically for the treatment of atherosclerosis, cerebral infarction, and cerebral ischemia. This study aimed to determine the anti-inflammatory effects of PN against bleomycin-induced pulmonary fibrosis in mice. First, in an in vitro study, culture media containing lipopolysaccharide (LPS) was used to stimulate macrophage cells (RAW 264.7 cell line). TNF-α and IL-6 levels were then determined before and after treatment with PN extract. In an animal model (C57BL/6 mice), a single dose of PN (0.5 mg/kg) was administered orally on Day 2 or Day 7 postbleomycin treatment. The results showed that TNF-α and IL-6 levels increased in the culture media of LPS-stimulated macrophage cells, and this effect was significantly inhibited in a concentration-dependent manner by PN extract. Histopathologic examination revealed that PN administered on Day 7 postbleomycin treatment significantly decreased inflammatory cell infiltrates, fibrosis scores, and TNF-α, TGF-β, IL-1β, and IL-6 levels in bronchoalveolar lavage fluid when compared with PN given on Day 2 postbleomycin treatment. These results suggest that PN administered in the early fibrotic stage can attenuate pulmonary fibrosis in an animal model of idiopathic pulmonary fibrosis

Comparison of single-incision mini-slings (Ajust) and standard transobturator midurethral slings (Align) in the management of female stress urinary incontinence: A 1-year follow-up

AbstractObjectiveTo investigate the effectiveness and safety of a new single-incision mini-sling (SIMS)—Ajust—compared with the standard transobturator midurethral sling (SMUS)—Align—for the treatment of female stress urinary incontinence (SUI).Materials and MethodsA retrospective cohort study was conducted between January 1, 2010 and August 31, 2012. Women with SUI who underwent either SMUS-Align or SIMS-Ajust were recruited. The primary outcomes included operation time, estimated operative blood loss, postoperative pain, and complications. The secondary outcomes included subjective and objective success, defined as an International Consultation on Incontinence Questionnaire (ICIQ) score of 0 or improvement as felt by the patient and a long-term complication, such as dyspareunia and mesh erosion after 6 months and 12 months of follow-up.ResultsA total of 136 patients were enrolled, including 76 receiving SMUS-Align and 60 receiving SIMS-Ajust. Baseline characteristics of the patients in both groups were similar, without a statistically significant difference. Primary outcomes between both groups were similar, except that women treated with SIMS-Ajust had statistically significantly shorter operation time (p = 0.003), less intent to treat (p < 0.05), and earlier postoperative discharge (p = 0.001) than women treated with SMUS-Align. Secondary outcomes were similar without a significant difference between the two groups (93% vs. 88% success rate in each group).ConclusionOur results showed that SIMS-Ajust was not inferior to SMUS-Align with respect to success rate, and might have a slight advantage in early discharge. A long-term follow-up or prospective study is needed to confirm the above findings

The Combined Treatment of Chinese Herbal Medicines is Correlated with a Lower Risk of Rheumatoid Arthritis in Patients with Depression: Evidence from a Population-Based Patient–control Study

Background: Major depression places psychological strain on the individual that may increase the risk of developing rheumatoid arthritis (RA). Though the use of Chinese herbal medicines (CHMs) is widespread in clinical practice, its effect on the prevention of RA incidents is still unknown. This study aimed to evaluate the association between CHMs use by patients with depression and their subsequent risk of being diagnosed with RA
