In conclusion, the analyzed TAM and STRMK mutations have a comparable impact on STIM1 protein function and downstream effects of excessive Ca2+ entry, highlighting that TAM and STRMK involve a common pathomechanism.Count data sets are traditionally analyzed using the ordinary Poisson distribution. However, such a model has its applicability limited as it can be somewhat restrictive to handle specific data structures. In this case, it arises the need for obtaining alternative models that accommodate, for example, (a) zero-modification (inflation or deflation at the frequency of zeros), (b) overdispersion, and (c) individual heterogeneity arising from clustering or repeated (correlated) measurements made on the same subject. Cases (a)-(b) and (b)-(c) are often treated together in the statistical literature with several practical applications, but models supporting all at once are less common. Hence, this paper’s primary goal was to jointly address these issues by deriving a mixed-effects regression model based on the hurdle version of the Poisson-Lindley distribution. In this framework, the zero-modification is incorporated by assuming that a binary probability model determines which outcomes are zero-valued, and a zero-truncated process is responsible for generating positive observations. Approximate posterior inferences for the model parameters were obtained from a fully Bayesian approach based on the Adaptive Metropolis algorithm. Intensive Monte Carlo simulation studies were performed to assess the empirical properties of the Bayesian estimators. The proposed model was considered for the analysis of a real data set, and its competitiveness regarding some well-established mixed-effects models for count data was evaluated. A sensitivity analysis to detect observations that may impact parameter estimates was performed based on standard divergence measures. The Bayesian p -value and the randomized quantile residuals were considered for model diagnostics.
To investigate health anxiety-related factors in the early stages of pandemic in Turkey.
This study included 1046 participants who responded to the online survey anonymously between 28 March and 04 April 2020.
Demographic data, postpandemic attitudes towards the elderly and precaution-taking behaviors were health anxiety-related factors. The main predictors of the health anxiety were the level of hopelessness, perception of self, time spent on social media, and following COVID-19 pandemic-related news.
The results of this study are important in terms of understanding the health anxiety during the pandemic and providing data support for the proper interventions.

The genotype data of 1,230 bulls and 1,645 cows were considered in our study. The reproductive traits evaluated were interval from calving to first service (ICF), calving interval (CI) and daughter pregnancy rate (DPR) measured during the first four parities. ROCK inhibitor Reliability and rank correlation were used to compare the H-AR with the traditional pedigree-based autoregressive models (A-AR). In addition, a validation study was performed considering different scenarios. Higher genomic estimated breeding values (GEBV) reliabilities were obtained for genotyped bulls when evaluated under the H-AR model, with emphasis on bulls with less than 9 daughters. For this group, the averages of GEBV reliabilities corresponded to 0.62, 0.69 and 0.62 for ICF, CI and DPR, respectively, while the averages obtained by the A-AR model were 0.27, 0.15 and 0.16. The validation study was favourable to H-AR. The best results were observed in the scenario where genotyped cows were combined with contributing bulls (genotyped bulls with daughter or relationship information in the population). Overall, the results suggest that ssGBLUP methodology under the autoregressive model is a feasible and applicable approach to be used in genomic analyses of longitudinal reproductive traits in Portuguese Holstein cattle.
To observe the microvascular architecture in the placental bed and explore the feasibility and clinical utility of MV-Flow imaging (Samsung Medison Co, Ltd, Seoul, Korea) during normal pregnancy and fetal growth restriction (FGR).
Placental microvascular structure ultrasound imaging by MV-Flow was performed on 227 unaffected and 17 FGR fetuses between 11 and 41 weeks’ gestation. A placental vascular index (VI
) was acquired by application of various MV-Flow regions of interest (ellipse, rectangle, and manual trace). Unaffected control and FGR groups were assessed for umbilical artery, middle cerebral artery, and uterine artery pulsatility indices and the cerebroplacental ratio calculated by ultrasound.
No significant difference in the VI
by varying regions of interest or placental regions was observed in the control group. The VI
in the first trimester was lower than that in the second and third trimesters, with 5th through 95th percentile normal VI
reference values of 18.39 to 63.79 for 13.6 wethe level of the stem villi and villous leaves, and the VIMV provides for quantification of tissue vascularity. MV-Flow is a potentially powerful and promising tool to explore placental microvascular perfusion and provide new information on a host of pregnancy-related conditions.The aim of this study was to validate the Trait Emotional Intelligence Questionnaire (TEIQue v. 1.5) in a Lebanese sample and compare its factorial structure to that of a UK sample. There were similar gender and age distributions in both samples as well as satisfactory structural reliabilities at the global, factor, and facet levels. Results from exploratory factor analysis showed a four-factor structure similar to that originally obtained by the author of the questionnaire. There were strong correlations between the factor scores derived from the two datasets (≥.90). Tucker congruence supported the similarity between the Lebanese and UK factors. Independent-samples t tests showed that Lebanese participants scored higher on the Sociability factor and the facets of self-esteem, social awareness and emotion perception, whereas UK participants scored higher on the facets of stress management, optimism and relationships. Gender differences are also reported, and recommendations for future research discussed.
