Among current state-of-the-art estimation methods for multilevel IRT models, the two-stage divide-and-conquer strategy has practical advantages, such as clearer definition of factors, convenience for secondary data analysis, convenience for model calibration and fit evaluation, and avoidance of improper solutions. However, various studies have shown that, under the two-stage framework, ignoring measurement error in the dependent variable in stage II leads to incorrect statistical inferences. link= Smad3 signaling To this end, we proposed a novel method to correct both measurement bias and measurement error of latent trait estimates from stage I in the stage II estimation. In this paper, the HO-IRT model is considered as the measurement model, and a linear mixed effects model on overall (i.e., higher-order) abilities is considered as the structural model. The performance of the proposed correction method is illustrated and compared via a simulation study and a real data example using the National Educational Longitudinal Survey data (NELS 88). Results indicate that structural parameters can be recovered better after correcting measurement biases and errors.

How people deal with ridicule and being laughed at plays a role in romantic life. We extend the research on the fear of being laughed at (gelotophobia), joy in being laughed at (gelotophilia), and joy in laughing at others (katagelasticism) by testing their associations with romantic jealousy and its consequences for relationship satisfaction (RS).

Our study is based on Actor-Partner Interdependence Model (APIM) analyses of self and partner ratings of the laughter-related dispositions using data from 228 opposite-sex couples. APIM mediation analyses estimated indirect effects of jealousy on the associations between the dispositions and RS.

As expected, gelotophobia-related positively to jealousy in actors, whereas gelotophilia and katagelasticism showed differential relationships. The analysis of partner effects showed that the actual expressions in the dispositions are unrelated to jealousy but perceived expressions account robustly for experiences of jealousy beyond self-ratings. Finally, jealousy had indirect effects on the associations between the dispositions and RS.

These findings contribute to our understanding of the role of dealing with ridicule and laughter in romantic life. We embed the findings into the literature, discuss practical implications, and derive future directions to expand the knowledge on gelotophobia, gelotophilia, and katagelasticism in romantic life.

To gain insight into parents' perspectives about their decision-making process concerning nusinersen treatment for their child, including perceived needs and concerns, and to explore factors that influence this process.

This was an exploratory qualitative interview study among parents of children with spinal muscular atrophy types 1 to 3. Data were analysed using inductive thematic analysis.

Nineteen parents of 16 children representing 13 families participated. A wide variety of perspectives was reported ranging from a biomedical approach, which focused on battling the disease, to a holistic approach, which aimed for a good quality of life for their child. The most important factors that helped parents to decide were honest and neutral communication with their physician and access to available information.

It is important physicians understand that there are different perspectives influencing the decision-making process. Physicians should create an environment that allows parents to accept or reject tating honestly and openly with them and by discussing both options extensively. Clear information about pros and cons, recent developments in research, and the experiences of other parents should be made available to enable parents to make an informed decision. What this paper adds Parents perceived different needs and concerns about nusinersen treatment, which emphasized individual differences. Parents' perspectives varied from battling the disease to preserving quality of life. Life expectancy, stopping deterioration, and improving quality of life were the perceived benefits of nusinersen treatment. Open communication about the pros and cons of treatment with clinicians facilitated decision-making. Clear and honest information facilitated the alignment of values and goals.Sexual segregation in foraging strategies has been little studied in marine species with slight sexual size dimorphism (SSD), particularly regarding the role of environmental conditions and fishery activities. link2 Sexual differences in fishery attendance are of particular concern because uneven mortality associated with bycatch may exacerbate impacts in wildlife populations. Using a seabird species with slight SSD, the Scopoli's shearwater Calonectris diomedea, we assessed sexual differences in foraging strategies and evaluated whether annual environmental conditions and fishery activity shaped such differences. We used a 4-year dataset combining bird GPS tracking, stable isotope analysis, the North Atlantic Oscillation index (NAO, as main proxy of the annual environmental conditions), and fishing vessel positioning data (Vessel Monitoring System, VMS) from the North Western Mediterranean, a region under intense fishery pressure. From 2012 to 2015, we tracked 635 foraging trips from 78 individuals. Females showedn foraging strategies can lead to an unbalanced exposure to relevant threats and have implications for the conservation of long-lived species.Type 1 diabetes (T1D) is a chronic autoimmune disease characterized by pancreatic islet β cell loss and dysfunction resulting in insulin deficiency and hyperglycemia. During a presymptomatic phase of established β cell autoimmunity, β cell loss may first be evident through assessment of β cell secretory capacity, a measure of functional β cell mass. Reduction in pancreatic islet β cell reserve eventually manifests as impaired first-phase insulin response to glucose and abnormal glucose tolerance, which progresses until the functional capacity for β cell secretion can no longer meet the demand for insulin to control glycemia. A functional β cell mass of ∼25% of normal may be required to avoid symptomatic T1D but is already associated with dysregulated glucagon secretion. With symptomatic T1D, stimulated C-peptide levels >0.60 ng/mL (0.200 pmol/mL) indicate the presence of clinically meaningful residual β cell function for contributing to glycemic control, although even higher residual C-peptide appears necessary for evidencing glucose-dependent islet β and α cell function that may contribute to maintaining (near)normal glycemia. Smad3 signaling link3 β cell replacement by islet transplantation can restore a physiologic reserve capacity for insulin secretion, confirming thresholds for functional β cell mass required for independence from insulin therapy.There is an apparent reciprocal relationship between magnesium ammonium phosphate (MAP, struvite) and calcium oxalate (CaOx) urolithiasis incidence rate in cats. The number of struvite uroliths submitted for analysis over the past 35 years has been decreasing, with an increase in CaOx urolith submissions. Commercial diets aimed to dissolve struvite uroliths are typically acidified, and it has been suggested that dietary acidification increases urinary calcium excretion and the risk of CaOx crystallization. The objective of this study was to assess the effect of urine acidification on the relative supersaturation (RSS) of CaOx in cats, as a representation of crystallization risk. Four diets were extruded to contain identical nutrient contents, but with gradual acidification (0, 0.6, 1.3 and 1.9% sodium bisulphate substituted sodium chloride in diets A, B, C and D respectively). Thirteen adult cats were fed each diet sequentially for a minimum of 10 days. Average urine pH was 6.4, 6.2, 6.0 and 5.9 on diets A, B, C and D respectively (p less then 0.0001). Struvite RSS decreased on diets inducing more acidic urine pH (p less then 0.0001). Urinary calcium excretion and concentration increased with diets inducing lower urine pH (p less then 0.0001), but oxalate excretion and concentration decreased (p less then 0.001). CaOx RSS was not different between diets (p = 0.63). These results suggest that a lower diet base excess and resulting urine pH to support struvite dissolution do not increase the risk for CaOx crystallization in the range of urine pH representative of most commercial feline diets. Long-term studies are needed to confirm this.In clinical and experimental non-alcoholic steatohepatitis (NASH), the origin of the scar-forming myofibroblast is the hepatic stellate cell (HSC). We used foz/foz mice on a Western diet to characterize in detail the phenotypic changes of HSCs in a NASH model. Smad3 signaling We examined the single cell expression profiles (scRNA-Seq) of HSCs purified from the normal livers of foz/foz mice on a chow diet, in NASH with fibrosis of foz/foz mice on a Western diet, and in livers during regression of NASH after switching back to a chow diet. Selected genes were analyzed using immunohistochemistry, qRT-PCR, and shRNA-knockdown in primary mouse HSCs. Our analysis of the normal liver identified two distinct clusters of quiescent HSCs that correspond to their acinar position of either pericentral vein or periportal vein. The NASH livers had four distinct HSC clusters, including one representing the classic fibrogenic myofibroblast. The three other HSC clusters consisted of a proliferating cluster, an intermediate activated cluster, and an immune and inflammatory cluster. link2 The livers with NASH regression had one cluster of inactivated HSCs, which was similar to, but distinct from, the quiescent HSCs. link3 Conclusion Analysis of scRNA-Seq in combination with an interrogation of previous studies has revealed an unanticipated heterogeneity of HSC phenotypes under normal and injured states.Nearly 100 years ago, Charles Elton described lemming and vole population cycles as ecological models for understanding population regulation in nature. Yet, the mechanisms driving these cycles are still not fully understood. These rodent populations can continue to cycle in the absence of predation and with food supplementation, and represent a major unsolved problem in population ecology. It has been hypothesized that the social environment at high population density can drive selection for a low-reproduction phenotype, resulting in population self-regulation as an intrinsic mechanism driving the cycles. However, a physiological mechanism for this self-regulation has not been demonstrated. We manipulated population density in wild meadow voles Microtus pennsylvanicus using large-scale field enclosures over 3 years and examined reproductive performance and physiology. Within the field enclosures, we assessed the proportion of breeding animals, mass at sexual maturation, and faecal androgen and oestrogen metabolites.
