The third phase was conducted with another sample (N=430) composed of "informants" (n=215), who completed the TAS-20-IF, and "targets" (n=215), who completed the TAS-20 (informants were nominated by the targets).

The psychometric properties (items and scales) of both versions were adequate and the three-factor structure of the TAS-20-IF was supported; the correlation between the two versions was statistically significant and the factor structures were similar.

Although further research is needed to replicate these findings, especially in clinical samples, the results support the reliability and validity of the TAS-20-IF.

However, there are few studies focused on the construction of artificial implants with periosteum-mimetic effect. To emulate the primary role of natural periosteum or endosteal tissues in bone regeneration, here we provide a functional biomimetic membrane with micropatterns of site-specific biomineralization. The micropattern is generated by using printed hydroxyapatite nanoparticles (HANPs), combined with selective growth of biomineralized apatite and in situ coprecipitation with growth factors. The biomimetic membrane can sustainably provide a periosteum-mimetic microenvironment, such as long-term topographical guidance for cell recruitment and induced cell differentiation, by releasing calcium phosphate and growth factors. We demonstrated that rat mesenchymal stem cells (rMSCs) on such biomimetic membrane exhibited highly aligned organization, leading to enhanced angiogenesis and osteogenesis. In the rat calvarial defect model, our biomimetic membranes with biomineralized micropatterns could significantly enhance vascularized ossification and accelerate new bone formation. The current work suggests that the functionally biomimetic membranes with specific biomineralized micropatterns can be a promising alternative to periosteal autografts, with great potential for bench-to-bedside translation in orthopedics.Radioimmunoassay (RIA) is an extremely specific and a highly sensitive type of immunoassay, but the long incubation time and generation of radioactive wastes limit the use of RIA. To complement these disadvantages of RIA, we suggest an advanced type of RIA based on a lab-on-a-chip (LOC) platform μ-RIA. We designed a microfluidic chip for RIA and optimized the procedures of μ-RIA analysis, including surface modification, immunoreaction time, and washing. Based on the optimized conditions, we conducted a radioimmunoassay on the μ-RIA platform using a commercial RIA kit. With the μ-RIA, 5 min are adequate for analysis. The amount of reagent consumption is significantly reduced compared with conventional RIA. The standard curve with R2 = 0.9951 shows that we can quantitatively evaluate the amount of antigen present in unknown samples. We show the applicability of μ-RIA for the analysis of biomolecules and the potential of μ-RIA to be a novel platform for high-throughput analysis.The mean excitation energy 〈I〉 is a fundamental quantity in radiation physics, concerning energy deposition in matter and absorbed dose analytical estimations for charged particles. The stopping of charged particles in different materials strongly depends on this parameter among others. This work intends to contribute with insights for some issues, usually treated not in detail in the theory of stopping power, as the analytic and theoretic assessment of 〈I〉-value for different relevant materials. A methodology is proposed and described aimed at providing the procedure for the 〈I〉 calculation framework, based on the definition of the mean excitation energy using the dielectric response function is analytically integrable if the inelastic cross section parameters are known. Beta Amyloid inhibitor Some dielectric models were studied, aimed at calculating the 〈I〉-value for liquid water by theoretical means, reaching the conclusion that a decay at least of the order of ω-2 in frequency (energy) is needed as weak condition of the optical energy-loss function for the integrals to converge. Afterwards, the first four discrete excitation levels and the diffuse bands for water are treated in a fully analytical scheme, and further compared with numerical results, providing the contribution of these levels to 〈I〉, with the aim of testing the proposed analytical model.

This cross-sectional cohort study quantified the disparities in MS risk by age, sex, nativity from 1980 to 2019 in Kuwait.

Age-standardized MS incidence rate (ASIR) (per 100,000 person-years) overall and by subcohorts defined by cross-classification of the period (5-year groups) of diagnosis, age at onset, sex (female or male) and nativity (Kuwaiti or non-Kuwaiti) were computed and analyzed using multivariable negative binomial model.

Overall MS ASIR (per 100,000 person-years) was 3.41 (95% CI 1.61, 5.21), which exponentially increased from 1980 to 2014 before drifting downward in 2015-2019 period. Compared with adults (age ≥ 40 years), males, non-Kuwaiti residents respectively, young adults (20-39 years), females and Kuwaiti nationals were significantly (p<0.05) more likely to develop MS after adjusting for the period effect.

A high overall MS ASIR (per 100,000 person-years) was recorded with substantial temporal variation between 1980 and 2019. Young adults (20-39 years), females and Kuwaiti nationals constituted MS high-risk groups. The knowledge of underlying interface pathways between genetic and environmental factors may provide insights into MS pathogenesis and leads for future research.
