Although several individual case-control studies have evaluated the role of protein tyrosine phosphatase non-receptor 22 (PTPN22) gene rs2476601 single nucleotide polymorphism (SNP) in conferring a risk for RA, the results have been conflicting. Hence, this meta-analysis was conducted to come up a solution for this issue. METHODS In order to search for studies assessing the association between PTPN22 gene rs2476601 SNP and the risk of RA, a systematic search was conducted in the main databases, including PubMed, Scopus, and Web of Science prior to December 2019. The odds ratio (OR) and corresponding 95% confidence interval (CI) was calculated to assess the possibility of association risk. RESULTS The literature search identified 53 case-control studies. The pooled analysis detected significant positive association of rs2476601 in all genetic models, including dominant model (OR= 1.63, 95% CI= 1.47 - 1.79, P less then 0.001), recessive model (OR= 2.50, 95% CI= 2.06 - 3.05, P less then 0.001), allelic model (OR= 1.72, 95% CI= 1.53 - 1.94, P less then 0.001), TT vs. CC model (OR= 2.79, 95% CI= 2.28 - 3.41, P less then 0.001), and CT vs. CC model (OR= 1.58, 95% CI= 1.45 - 1.74, P less then 0.001). Analyses based on population stratification indicated that rs2476601 SNP strongly increased risk of RA in Caucasians and Africans under all genotype models. CONCLUSIONS This meta-analysis report that PTPN22 gene rs2476601 SNP increases RA risk, especially in Caucasians and Africans. This article is protected by copyright.

MATERIALS AND METHODS A healthy non-periodontitis group (H-NP)(n=20), a systemically healthy chronic periodontitis group (H-P)(n=20), a non-periodontitis group with OC (OC-NP)(n=12), and a chronic periodontitis group with OC (OC-P)(n=16) formed the study groups. The levels of NE and IGFBP7 were measured in gingival crevicular fluid (GCF) and saliva. In addition, oxidative status was determined by evaluating total oxidant status (TOS), total antioxidant status (TAS) and OSI (TOS/TAS). RESULTS GCF NE was higher in all the groups compared to the H-NP group (p less then 0.01). Salivary NE was higher in the OC-P and H-P groups compared to the H-NP and OC-NP groups (p less then 0.05). Salivary IGFBP7 was significantly higher in the OC-NP and OC-P groups compared to the H-NP and H-P groups (p less then 0.001). click here GCF TOS and OSI levels were significantly higher in all groups compared to the H-NP group (p less then 0.05). CONCLUSIONS GCF NE levels were lower in healthy conditions compared to periodontal disease and OC. Salivary NE levels were higher in periodontal disease compared to states with no periodontal disease. Salivary IGFBP7 levels were higher in OC. Further analyses may help determine whether high salivary IGFBP7 levels distinguish OC from healthy conditions. This article is protected by copyright.

Upon ingestion, their bioavailability and functionality depend on hydrolysis of the glycosidic bond by endogenous or microbial glycosidases. Hence, it is essential to map the glycosidase activities towards phenolic glycosides present along gut. Therefore, the activity of three key glycosidases, that is α-glucosidase (αGLU), β-glucosidase (βGLU) and β-galactosidase (βGAL), was quantified in small intestinal mucosa and digesta of piglets at different gastrointestinal sites (stomach, three parts of small intestine, caecum and colon) and at different ages around weaning (10 days before and 0, 2, 5, 14 and 28 days after weaning). Activity assays were performed with p-nitrophenyl glycosides at neutral pH. The αGLU activities in mucosa and digesta were low (overall means 1.4 and 60 U respectively) as compared to βGLU (15.2 and 199 U) and βGAL (23.4 and 298 U; p less ell Verlag GmbH.PURPOSE To investigate the impact of dual readout bandwidths (dBW) in a dual echo fat/water acquisition and describe a dBW-rapid acquisition relaxation enhanced, or turbo spin echo sequence where the concept is used to improve SNR by removing dead times between refocusing pulses and avoiding redundant Chemical-shift encoded. METHODS Cramér-Rao bounds and Monte Carlo simulations were used to investigate a two-point fat/water model where the difference in bandwidths is incorporated. In vivo images were acquired at 1.5 and 3 T with the dBW-rapid acquisition relaxation enhanced, or turbo spin echo sequence. Typical bandwidth ratios were 12. SNR was compared with a single bandwidth sequence under identical scan parameters at 3T. RESULTS Monte Carlo simulations and Cramér-Rao analysis demonstrate that number of signal averages can be improved with dual bandwidths compared to conventional single bandwidth acquisitions. The dBW-rapid acquisition relaxation enhanced, or turbo spin echo sequence can acquire images with high readout resolutions with well-conditioned sampling. An SNR improvement of 52% was measured, in line with the theoretical gain of 54%. CONCLUSIONS The proposed dBW-rapid acquisition relaxation enhanced, or turbo spin echo sequence is a highly SNR-efficient two-point rapid acquisition relaxation enhanced, or turbo spin echo sequence without dead times, and can acquire images at higher resolutions than current vendor-supplied alternatives. © 2020 The Authors.

METHODS In this observational study, we recruited 92 smartphone-owning adults (≥ 18) with schizophrenia (45) and healthy controls (43). We installed an open-source smartphone app called mindLAMP to collect survey results and latencies (response times) over a period of 3 months. Surveys were scheduled for twice a week, but participants were instructed to take the surveys naturally as much or as little as they wanted. A total of 1,218 PHQ-9 surveys were completed across all participants over 3 months. RESULTS A total of 75 participants (39 with schizophrenia and 36 healthy controls) completed both the initial visit and follow-up, as well as provided at least one self-reported PHQ-9 survey through the app. We found that depression symptom severity and response latencies were correlated for both individuals with schizophrenia (Spearman's ρ = .
