This result suggested that high doses of A2 did not alter BF because of activating the α2 adrenergic receptor. Phosphorylation of aortic endothelial nitric oxide synthase (eNOS) increased with 10 µg/kg A2 alone or co-treatment with 100 µg/kg A2 and yohimbine, but not with co-treatment of 10 µg/kg A2 and carvedilol or 100 µg/kg A2 alone. These results imply that A2 does not directly activate eNOS but that shear stress from the increased BF might be associated with eNOS phosphorylation.Background The purpose of this study was to identify the expression of phosphatase and tensin homolog (PTEN) and its diagnostic value in colorectal cancer (CRC).Methods The expression level of serum PTEN at mRNA and protein level were determined using quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot analyses, respectively. Chi-square test was employed to explore the relationship between PTEN expression and clinical features of CRC patients. The receiver operating characteristics (ROC) curve was established to evaluate the diagnostic performance of PTEN in CRC.Results The expression of serum PTEN was significantly lower in patients with CRC than that in healthy controls both at mRNA and protein level (p  less then  .05). Also, the low PTEN expression was significantly related to serosal invasion, lymph node metastasis and Ki-67, but had no relation with age, sex, tumor depth and tumor site. The area under ROC curve of 0.810 corresponding with a sensitivity of 97.79% and a specificity of 70.31% were obtained, which suggested PTEN could act as a diagnostic marker for CRC.Conclusion Altogether, serum PTEN expression was down-regulated and it participated in the development of CRC. Besides, it could act as an efficient and independent diagnostic marker for CRC patients.Cyclosporine-A (CsA) is a widely used immunosuppressant. In this study, we explore the pathway through which CsA suppressed the Porphyromonas gingivalis lipopolysaccharide (P.g-LPS)-induced increase in matrix metalloproteinase (MMP) activities in co-cultured human gingival fibroblasts (HGFs) and THP-1 monocytes. In the co-culture, we found that CsA inhibited the expression of cyclophilin A (CyPA), CD147 and the activities of MMPs, which were all induced by P.g-LPS. We also found that P.g-LPS and recombinant human CyPA increased activation of ERK1/2 and IκB (an NF-κB inhibitory protein), but CsA and the anti-CD147 antibody significantly inhibited these effects. Taken together, CsA in the presence of P.g-LPS might suppress MMP activities by blocking the CyPA/CD147 interaction that results in the inhibition of ERK1/2 and NF-κB signaling by interfering with the phosphorylation of ERK1/2 and IκB.Objective Since the observation of several deaths from amyotrophic lateral sclerosis (ALS) among Italian professional soccer players, an association between ALS and soccer has been postulated. The objective of the study is to investigate the association between professional soccer and the risk of ALS in a large cohort of former professional soccer players with prolonged follow-up. Methods All professional soccer players practicing in the period 1959-2000 were identified through the archives of an Italian soccer cards publisher. For each player, date and place of birth, playing role, and team history were recorded. Each player was followed since 15 years of age. Incident ALS cases were all soccer players first diagnosed during the period 1959-2018. The expected incidence rate was the number of ALS cases/100,000 person-years expected in the cohort. SIR was the ratio between observed and expected incidence rate. selleckchem Results 34 ALS cases were detected. The number of expected cases was 17.8. The SIR was 1.91 (95% CI 1.32-2.67) in the entire sample and 4.66 (95% CI 2.66-7.57) in subjects aged less than 45 years. The mean age at diagnosis was 45.0 years. Compared to the mean age of onset of ALS in the general population (65.2 years), the disease in former soccer players occurred 20.2 years earlier. Conclusions Professional soccer players are at higher risk of developing ALS than the general population. Soccer players with ALS develop the disease at a younger than expected age.Objectives (a) to estimate the accuracy of International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) code for amyotrophic lateral sclerosis (ALS) in the Hospital Discharge Database (HDD) of the Italian region Friuli-Venezia Giulia; (b) to identify the predictors of a true positive ALS code; (c) to compare incident and prevalent cases obtained from HDD with those identified in a retrospective population-based study. Methods Records of all patients discharged 2010-2014 with an ICD-9-CM code for ALS and other motor neuron diseases were extracted from the HDD. For each record, all the available clinical documentation was evaluated to confirm or reject the diagnosis of ALS. ALS incident and prevalent cases were identified. Validity measures were calculated both overall and stratified by patient and hospitalization characteristics. Adjusted odds ratio (aOR), with 95% confidence interval (95%CI), of a true positive code was estimated using unconditional logistic regression. Results ALS code had sensitivity 92.9%, specificity 75.3%, positive predictive value (PPV) 92.3%, and negative predictive value (NPV) 76.8%. A true positive ALS code was predicted by concurrent codes for respiratory interventions (aOR 3.82; 95%CI 2.09-6.99), primary position code (2.78; 1.68-4.62), non-programed hospitalization (2.06; 1.18-3.61), male patient (1.56; 1.06-2.29), and hospitalization length less then 14 days (1.42; 1.07-2.84). Two hundred and thirty-six prevalent and 187 incident cases were identified, 84% of those detected in the population-based study. Conclusion ALS code shows very good accuracy and identifies a high percentage of true positive, incident and prevalent cases, but additional sources and an algorithm based on selected variables may further improve case identification.Background Birth measures of twins are potentially influenced by sex of co-twin.Aim To analyse the association between sex of co-twin and birth weight, length and ponderal index in twin infants from Yucatan, Mexico.Subjects and methods A total of 2057 twin pairs born during 2008-2017 were analysed. Female-female (F-F), male-male (M-M) and male-female (M-F) twin pair types were defined. Multiple linear regression models were used to analyse the association of (1) being female from M-F pairs and birth measures among overall female infants (M-F and F-F), and (2) being male from M-F pairs and birth measures among overall male infants (M-F and M-M). The length of gestation and mothers' age and level of education were used as covariates.Results Models showed that being male from M-F pairs was associated with increases of 81 g in birth weight and 0.61 cm in length, compared to males from M-M pairs, and being female from opposite-sex pairs was associated with increases of 0.36 cm in length, compared to females from same-sex pairs.
