Published: February 2022

Objective To analyze the relation among insomnia, excessive daytime sleepiness and the excessive use of technologies in medical students.
Methods The study was approved by the Local Ethics Committee of the institution. Students from the 1st and 2nd year of medical graduation students participated. Three questionnaires were used: Sleep Time-Related Information and Communication Technology, Insomnia Severity Index and the Epworth Sleepiness Scale. The data were described and compared by gender and year of graduation by the Students T Test, and correlated to the use of technology, insomnia and excessive daytime sleepiness by Pearsons Correlation (adopted the significance level of p <0.05).
Results 106 students (41 male) participated, expressing perception of insomnia in 76.4%, 34% with excessive daytime sleepiness, and 38.3% had a high use of technology related to sleep. There was a correlation between the use of technologies both with insomnia (r = 0.393; p = < 0.001), as well as with excessive daytime sleepiness (r = 0.228; p = 0.019).
Conclusion An important frequency of insomnia was found associated with the excessive use of technologies at the bed, with repercussions of daytime sleepiness. This demonstrates the importance of actions to raise awareness and education about correct sleep hygiene in medical students.

Objective To evaluate the subjective sleep pattern in hospitalized patients.
Methods This is a cross-sectional design developed with 230 patients in a university hospital in northeastern Brazil from September 2017 to March 2018. We included patients 18 years old or older, hospitalized for a minimum of 48 hours and a maximum of five days, with stable clinical conditions and preserved guidance. For data collection, a structured questionnaire was used and the subjective sleep pattern was assessed using Visual Analog Sleep Scales. Univariate and bivariate statistics were calculated using IBM® SPSS® software, version 23.0.
Results In the hospitalization, the Disorder, Effectiveness, and Supplementation scales reached scores of 208.7 points, 353.8 points, and 62.9 points, respectively. The clinical characteristics that interfered with sleep were the practice of regular physical activity (p = 0.024) and a higher body mass index (p = 0.033). We also observed statistically significant differences between VAS scores and factors influencing sleep.
Conclusion There was a certain level of sleep disturbance during the hospitalization period, and consequently the need for sleep supplementation during the day. We also observed that some factors negatively influenced the quality of hospital sleep.

Authors: Fujii Mai , Hayashi Masayuki , Teng Cheong Lieng 
Published: February 2022

Objective The purpose of this study was to compare the duration of sleep and nap patterns between children in private kindergartens and those in a tabika-transit facility, in Malaysia.
Methods The sleep duration of children aged 3-6, who attended either a kindergarten or a childcare transit facility (tabika-transit in Malay) was investigated. Observational sleeping records were maintained for 24 hours, over 14 consecutive days. A self-administered questionnaire for caregivers investigated the children’s lifestyles. Naps were optional at kindergartens but mandatory at the tabika-transit.
Results Of 35 participating children, data from 33 were analyzed. All respondents belonged to the Malay ethnicity, with 16 boys (48.5%) and 17 girls (51.5%). The average age of the children was 5.4 years; 11 of them were from kindergartens and 22 from a tabika-transit. The children slept longer and woke up later on weekends than on weekdays. There was a significant difference in the naptaking rate between the two groups; it was 100% in the tabika-transit, and 30% in the kindergartens during weekdays. However, on weekends, 19 of 22 tabika- transit children did not nap on any of the days (86.4%). The kindergarten group’s naps showed no outstanding differences between weekdays and weekends. Concerning the bedtime and wake-up times, no differences were found between the two groups.
Discussion During weekdays, all children in the tabika-transit took naps, whereas one-third of them did in the kindergartens. Larger study is needed to assess how this mandatory napping style affects children’s lifestyle and development.

Published: February 2022

Background
Urbanization and global warming are generating ecological degradation and land pattern alteration problems in natural wetlands. These changes are greatly affecting the ecological services of wetlands. Therefore, there is an urgent need to explore the relationship between pollutants and land-use type for wetland restoration purposes. Zaozhadian Lake is a freshwater wetland in the North China Plain, which is facing degradation and land-use types changes. An experiment for analyzing soil pollutants was conducted in three land-use types of farmland, lake, and ditch in the Zaozhadian Lake. The aims of this study were to identify the distribution, pollution degree, and sources of pollutants in different land-use types, and to explore the influence of land-use type changes on contamination.

Methods
In this study, surface sediments (0–10 cm) of three land types (farmland, lake, and ditch) in Zaozhadian Lake were collected, and heavy metals (Cu, Ni, Zn, Pb, Cd, Cr, Hg), As, total nitrogen (TN), total phosphorus (TP) and organic matter (OM) were determined. Kriging interpolation was used to visualize the pollutants distribution. The pollution degree of TN and TP was evaluated by the Nemerow pollution index. The pollution of heavy metals and As was evaluated by the geological accumulation index (Igeo) and the potential ecological risk index (RI). Then, dual hierarchical clustering analysis and the principal component analysis were performed to further analyze the impact of land type changes on pollutants.

Results
The heavy metal contents in the farmland were higher than other areas, while the TN (3.71 ± 1.03 g kg-1) and OM (57.17 ± 15.16 g kg−1) in lake sediments were higher than that in other regions. Farmland, lake, and ditches had low ecological risks, with RI values of 84.21, 71.34, and 50.78, respectively. The primary heavy metal pollutants are Pb, Cu, and Ni. Furthermore, Cu, As, Ni, Pb, and Zn were primarily derived from agriculture pollution, the source of Cd was the industrial pollution, and Cr mainly originated from natural sources. Nutrients primarily came from the decomposition of aquatic animals, plants, and human-related activities. When the lake area was converted into farmland, the heavy metal concentrations in the soils increased and the TN and OM decreased. Based on the results, this study put forward key strategies including the adjustment of the land-use type and restriction of the entry of pollutants into the wetland ecosystems in the Zaozhadian Lake. More attention should be paid to the impact of land-use type change on pollutants in wetlands.

Published: February 2022

Objective
The purpose of the present study was to determine the effects of starch sugar by-product (SSB) feeding on the rumen in-vitro digestibility, in situ disappearance rate, and lactating dairy cow.

Methods
To determine the rumen in vitro digestibility, 50 mL of the buffer-rumen fluid mixture was dispensed into a 125 mL serum bottle containing 0.5 g of dry matter (DM) of substrates. Nitrogen gas (N2, 99.9% pure) was flushed into the serum bottles and three replications were incubated at 0, 2, 4, 8, 16, 24, and 48 h. To determine the in-situ disappearance rate, SSB was incubated for 0, 2, 4, 8, 16, 24, and 48 hours in nylon bags (5 × 10 cm, 45*m pore size) placed within the ventral sac of two cannulated Holstein cows.. A total of sixteen Holstein Friesian cows (60.5 ± 20.4 months old, 706.8 ± 3.4 kg initial body wieght) fed experimental diets during the experimental periods. The treatments were basal diet (control) and 3.0% DM of SSB, with the diet formulated according to national research council (NRC) nutrient requirements of dairy cattle guideline. An experiment was conducted with a randomized block design for six weeks based on body weight.

Results
Soluble fraction (fraction a) of DM and crude protein (CP) was 28.99 and 11.92%DM, fraction b of DM and CP was 44.63 and 31.61% DM, and c value of DM and CP was 26.38 and 56.47%DM. As an increase SSB level in total mixed ration (TMR), there was a decrease in gas production at 0, 16, and 48 h (p < 0.05). As an increase SSB level in TMR, there was a decrease in acetate to propionate ratio at 8, 16, 24, and 48 h (p < 0.05). Dry matter intake, milk production, and milk composition did not differ between the treatments. All blood profile contents did not differ between treatments.

Conclusion
A diet containing 3.0% SSB could be fed to ruminants without adverse effects on rumen fermentation.

Published: February 2022

A violência é um dos grandes problemas brasileiros e uma importante questão para a Psicologia como ciência e profissão. Diante disso, o presente texto, tem como objetivo expor, do ponto de vista psicológico, a explicação psicossocial de Martín-Baró para a violência, e, refletir criticamente sobre o papel da Psicologia em relação ao enfrentamento às condições que promovem violência social. A violência precisa ser compreendida como um fenômeno psicossocial, quando assumimos os pressupostos da constituição social do psiquismo e da unidade dialética sujeito-sociedade com propósito de superar as dicotomias comumente atribuídas a essa relação. Conclui-se que a obra de Martín-Baró sobre violência contém explicações importantes que precisam ser apropriadas pela Psicologia, e que sob a perspectiva histórico-dialética, presente na delimitação do seu objeto e da sua metodologia, assume caráter ético e político.

Published: February 2022

AbstractThis qualitative exploratory case study addresses constructs of educational inequity on a global scale through an iterative analysis of the cultural experiences of 61educators from South Africa and the United States. The project provided an online and in-person network for educators to discuss cross-cultural challenges, educational system assets, and inclusive strategies for supporting culturally and linguistically diverse learners. A shared professional development process, designed from an adapted Changemaking process, increased the knowledge, understanding, and application of innovative, culturally responsive inclusive practices of new teachers while also serving as an opportunity for veteran teachers to receive additional teacher training. Educators exchanged ideas on increasing positive classroom management, motivating learners using empathy, collaborating effectively, linking learning and postsecondary transition experiences, and improving partnership with families. This global and cultural exchange exposed them to unique and diverse educational perspectives, a critical aspect in supporting all learners within the K-12 educational system. Results of this project indicate that using the adapted Changemaking process increased educators' awareness of culturally responsive inclusive practices, allowed participants to make comparisons between global contexts, developed empathy, and inspired collaborative engagement and leadership within their individual educational settings.

Published: February 2022

Abstract
The success of seed‐based restoration in dryland regions of the world is often low or sporadic, with most mortality occurring between germination and emergence. Fungal pathogenesis is one process that may reduce seedling emergence and limit restoration success.
Our objective was to determine whether fungicide seed coatings constitute an economically viable strategy for increasing emergence by reducing fungal pathogenesis and mortality.
We performed an experiment across two sites and three years, using bluebunch wheatgrass (Pseudoroegneria spicata) as a model species. We found that fungicide coatings increased germination by 8.8% and emergence by 54.0% on average compared to the control. A cost analysis indicated that the fungicide coating was economically viable with an average estimated effective cost reduction of 18.8% under the study conditions.
There was a strong interaction (P < 0.001) between the effects of the fungicide coating, site and year on emergence. The fungicide coating increased emergence compared to the control in five of the six sites and years, with the effect ranging from a 33.7% decrease (P = 0.042) to a 150.9% increase (P = 0.004).
The observed interaction was likely related to the effect of the hydrothermal microsite environment on disease severity. In the site and year that the fungicide coating performed worse than the control, prolonged periods of exceptionally low soil moisture may have reduced disease severity through a variety of individual and community scale mechanisms.
Overall, these results indicate that fungicide seed coatings have the potential to improve dryland restoration efforts.

Published: February 2022

AbstractAs a key step during immune response, antigen recognition requires direct mechanical interaction between T cells and antigen presenting cells. Upon subjection to mechanical forces, mechanotransduction is triggered. In this study, the mechanical forces generated by water driven synthetic Au‐Zn nanomotors are used to activate mechanosensitive Jurkat T cells. The triggering and activation of the cellular Ca2+ channel is observed. It is revealed that the mechanosensitive cells experience different degrees of activation upon receiving different mechanical input signals and demonstrate that external mechanical forces can optimize T cell activation. Compared with T cell activation with cytokines which can lead to the risky widespread activation of T cells and systemic immune storm, nanomotors can present mechanical force and achieve localized immune cell stimulation. It is expected that mechano nanomotors will contribute to the emerging T cell immunology field and facilitate more comprehensive understanding of the T cell mechanical response and function.

AbstractElectronic transport through exfoliated multilayers of CrSBr, a 2D semiconductor of interest because of its magnetic properties, is investigated. An extremely pronounced anisotropy manifesting itself in qualitative and quantitative differences of all quantities measured along the in‐plane a and b crystallographic directions is found. In particular, a qualitatively different dependence of the conductivities σa and σb on temperature and gate voltage, accompanied by orders of magnitude differences in their values (σb/σa ≈ 3 × 102 to 105 at low temperature and negative gate voltage) are observed, together with a different behavior of the longitudinal magnetoresistance in the two directions and the complete absence of the Hall effect in transverse resistance measurements. These observations appear not to be compatible with a description in terms of conventional band transport of a 2D doped semiconductor. The observed phenomenology—and unambiguous signatures of a 1D van Hove singularity detected in energy‐resolved photocurrent measurements—indicate that electronic transport through CrSBr multilayers is better interpreted by considering the system as formed by weakly and incoherently coupled 1D wires, than by conventional 2D band transport. It is concluded that CrSBr is the first 2D semiconductor to show distinctly quasi‐1D electronic transport properties.
Facile, Real‐Time Identification of Blood Components with Self‐Powered Organic–Inorganic Heterostructure Photodetectors

Published: February 2022

AbstractA rapid and efficient opto‐electrical method for the determination of blood components is demonstrated through a tin oxide (SnO2) quantum dot (QD) fluorene copolymer heterojunction photodetector (FP‐PD). The photo‐active materials, the device structure, and the sensing system are carefully designed to provide miniaturization at a low cost. SnO2 QDs are synthesized with a one‐step solvothermal reaction and a photodetector, and then fabricated in a simple sequential spin‐coating process. Under optimal conditions, the SnO2 QD/FP‐PD shows remarkable responsivity, detectability, fast responses, and stability under self‐powered operation. In this research, optical characteristics of blood components, and interactions between the photodetector and blood components from illuminating two different wavelengths of ultraviolet light, are systemically investigated. Furthermore, three different blood component mixtures are successfully determined by the SnO2 QD/FP‐PD based on specific absorption phenomena, which provides a simple and efficient technique for emergency medical care and health monitoring systems.
