Funciones discursivas de las oraciones existenciales en español
Authors: Hernández Díaz Axel 
Published: March 2023

En algunas oraciones existenciales del español se observa cierta alternancia entre el carácter definido o indefinido de la frase nominal referida a la entidad existente. El verbo existencial prototípico haber, en contraste con otros existenciales, difícilmente participa de esta cualidad, a partir de lo que se observa una función discursiva presentativa específica de este verbo, la de introducir preponderantemente entidades nuevas en el discurso, función que lo distingue en términos semánticos y pragmáticos del resto de los verbos existenciales. En este trabajo se ofrece una explicación sobre las diferencias que subyacen a la alternancia de entidades existentes definidas o indefinidas en oraciones existenciales en relación con los conceptos tópico y foco. El análisis se basa en un corpus diacrónico constituido por estructuras pertenecientes al periodo comprendido entre los siglos XIII y XX.
'Dar/donar" i "fer + substantiu psicològic" en català antic (ss. XIII-XVI): Una aproximació basada en la gramàtica de construccions
Authors: Montserrat Buendia Sandra 
Published: March 2023

Hem observat que les construccions fer/donar + substantiu psicològic en català antic i medieval tenen una distribució diferent a la que es dóna en català actual. Concretament, actualment s’hi observa una predilecció per l’ús del verb fer, tria que contrasta amb altres llengües, com ara el castellà: fer por vs. dar miedo. Tanmateix, en la llengua antiga hi ha “no·∙m fa paor” al costat de “los que·∙t donen por”. En aquest article es presenta un estudi exhaustiu de les construccions fer+substantiu psicològic i donar+substantiu psicològic en català antic i medieval (ss. XIII-­‐‑XVI) amb un doble objectiu. D’una banda, descrivim quines són les construccions primitives de què parteixen aquestes construccions i quin és el procés pel qual esdevenen aptes per a l’expressió de les emocions. De l’altra, demostrem que les construccions amb fer i donar descriuen escenes diferents en la llengua antiga i que la preferència actual per fer és causada per la proximitat de les dues escenes en alguns contextos i per la freqüència d’ús. En aquest sentit ens han estat útils els conceptes proporcionats per la Gramàtica de Construccions Cognitiva (GCxC) de Goldberg (1996).

Published: March 2023

The emission lines of 140–180 nm are auroral bands of N2 Lyman–Birge–Hopfield, and they have been imaging targets of many satellites that need reflective mirrors. To obtain good imaging quality, the mirrors also should have excellent out-of-band reflection suppression as well as high reflectance at working wavelengths. We designed and fabricated non-periodic multilayer LaF3/MgF2 mirrors with working wave bands of 140–160 nm and 160–180 nm, respectively. We used a match design method and deep search method to design the multilayer. Our work has been utilized in the new wide-field auroral imager of China, and the application of these notch mirrors with excellent out-of-band suppression reduces the utilization of corresponding transmissive filters in the optical system of space payload. Furthermore, our work provides new routes for the design of other reflective mirrors in the far ultraviolet region.

Published: March 2023

Background
Overweight is a global public health problem with increasing trend especially in middle to lower socioeconomic country like Nepal. The nutritional status of adolescents being shaped by socio-cultural, environmental, and economic factors has also been impacted by their food habits and level of physical activity. The current nutritional shift and rapid urbanization had emerged overweight as an additional burden for consistently prevalent undernutrition issues. So, the study aimed to identify the prevalence of and risk factors for overweight among school adolescents.

Methods
A cross-sectional analytical study was carried out among random sample of 279 adolescents from nine schools of a Sub-metropolitan city of Nepal. The anthropometric measurement of the height and the weight were taken as per the standard. The odds ratio with a 95% CI was calculated and a p-value of ≤0.05 was considered as cut off for statistical significance by fitting into the final multivariable logistic regression.

Results
The overall prevalence of overweight was obtained as 9.31% (95% CI: 6.40–13.3). The early aged adolescents were more overweight than compared to middle-aged adolescents (AOR: 0.27, CI: 0.028–2.67) and late adolescents (AOR: 0.66, CI: 0.068–6.44) respectively. Similarly, adolescents residing in rural areas had 0.35 (AOR = 0.33, CI: 0.030–3.71) odds of being overweight compared to their counterparts. Adolescents with sedentary behavior were about 4 times (AOR = 3.51, CI: 0.79–15.54) more likely of being overweight than their counterparts.

Conclusion
Overweight among adolescents residing in urban areas has emerged as an alarming issue due to their unhealthy lifestyle habits. It is therefore pertinent to emphasize adolescents to maintain healthy weight status through health food habits and physical activity.

Authors: Ostadi Atieh , Arab‐Zozani Morteza , Zarei Elham , Ferns Gordon A. , Bahrami Afsane 
Published: March 2023

AbstractRadiodermatitis (RD) occurs in 95% of cancer patients undergoing radiation therapy. At present, there is no effective treatment for the management of this complication of radiotherapy. Turmeric (Curcuma longa) is a polyphenolic and biologically active natural compound with various pharmacological functions. The aim of this systematic review was to determine the efficacy of curcumin supplementation for reducing RD severity. This review complied with the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) statement. A comprehensive literature search was conducted in Cochrane library, PubMed, Scopus, Web of Science, and MEDLINE databases. A total of seven studies comprising 473 cases and 552 controls were included in this review. Four studies demonstrated that curcumin supplementation had a beneficial effect on RD intensity. These data provide evidence for the potential clinical use of curcumin in supportive cancer care. Further large prospective and well‐designed trials are warranted to exactly determine the “real effective extract, supplemental form and dose of curcumin” for RD prevention and treatment of patients receiving radiotherapy.

Is There Racial Bias in the Enforcement of Primary Seat Belt Laws? Evidence from Veil of Darkness Tests
Authors: Brewer Ben 
Published: March 2023

Abstract
State mandatory seat belt laws have become stricter over time, allowing for a vehicle to be stopped solely for a suspected seat belt infraction. While effective in reducing traffic fatalities, this additional discretion may also come with the possibility of increased racial targeting. Using individual-level traffic stop data, I combine recent advances in the Veil-of-Darkness test with a difference-in-difference identification strategy to estimate whether primary seat belt laws are associated with changes in the racial composition of seat belt stops. Results indicate that under primary seat belt enforcement, a black individual is 1.138–1.222 times more likely than a white individual to be stopped for a seat belt violation under the good visibility of daylight compared to the poor visibility of darkness. These additional stops end mostly in warnings, suggesting the law is used to increase the number of pretextual stops made, specifically on black drivers.
The role of IL-31 and IL-34 in the diagnosis and treatment of chronic periodontitis
Authors: Luo Ying , Ding Yi , Chen Yaduo 
Published: March 2023

AbstractThis study was devoted to demonstrating the role of IL-31 and IL-34 in the diagnosis and treatment of chronic periodontitis (CP). From the results, we found that the IL-31 and IL-34 levels were significantly increased in GCF and serum of CP patients compared with healthy controls or obese patients. Meanwhile, the area under the curve results further verified the diagnostic potential of IL-31 and IL-34 in terms of discriminating CP from obese patients at the GCF and serum levels. Finally, after 1 year of continuous treatment, we found that IL-31 and IL-34 levels were decreased in CP, suggesting their potential as biomarkers in CP treatment response. Monitoring GCF and serum levels of IL-31 and IL-34 contributed to CP detection and treatment response.
SMCG research on electromagnetic scattering in arid area
Authors: Jiang Fengyun 
Published: March 2023

Abstract
This article is devoted to the study of electromagnetic scattering characteristics in arid areas, and proposes environmental monitoring and improvement methods. A four-component soil dielectric model was established to study the relationship of soil dielectric constant with soil moisture and frequency. As the Monte Carlo Method combined with Gaussian spectral function was used to simulate the actual dry ground, the Sparse Matrix/Canonical Grid (SMCG) algorithm model based on the surface current equation was established to calculate the electromagnetic scattering coefficient of arid areas. To verify the correctness of the proposed algorithm, the results obtained by SMCG was compared with those calculated by Method of Moments (MOM), which showed great consistency. Many results were obtained by using the algorithm in this paper, based on the measured soil data in the southeastern area of Ejin Banner, Inner Mongolia. It was found that soil moisture content, area roughness and incident electromagnetic wave segment had influence on the scattering echo and showed regular change. The results of this paper are of guiding significance for soil moisture monitoring, desertification control and agricultural planting in arid areas.

Published: March 2023

Abstract
In order to solve the conflict between precipitated calcium carbonate (PCC) filling and alkyl ketene dimer (AKD) sizing for paper, this study explored two new flocculation methods: AKD and PCC were flocculated separately in the process ((A)(P)F), while the two pre-flocs from AKD and PCC were blended in the process ((AP)F). The result showed that increasing the dosage of the flocculant cationic starch (CS) resulted in a significant growth in the median size of PCC flocs and reduction in the specific surface area, turbidity, the negative charge of Zeta potential, as well as the adsorption capacity of PCC to AKD. Consequently the sizing degree and filler retention rate of the handsheets rose markedly. With 125 mg g−1 of CS, compared with the conventional process, the filler retention rate for (A)(P)F grew up to 86.16%; the Cobb60 values for both (AP)F and (A)(P)F declined, and the contact angle (CA) increased to 120.65° and 127.65° respectively. At the same time, the filler bondability factor (FBF) were increased due to the intensified bonding force between fibers, and resultantly the comparable mechanical properties of papersheets with a high level of filler retention was obtained from (AP)F and (A)(P)F flocculation processes.
Omega-3 polyunsaturated fatty acids alleviate early brain injury after traumatic brain injury by inhibiting neuroinflammation and necroptosis
Authors: Wu Yali , Zhang Jing , Feng Xiaoyan , Jiao Wei 
Published: March 2023

Abstract
Presently, traumatic brain injury (TBI) is a leading contributor to disability and mortality that places a considerable financial burden on countries all over the world. Docosahexaenoic acid and eicosapentaenoic acid are two kinds of omega-3 polyunsaturated fatty acids (ω-3 PUFA), both of which have been shown to have beneficial biologically active anti-inflammatory and antioxidant effects. However, the neuroprotective effect of ω-3 PUFA in TBI has not been proven, and its probable mechanism remains obscure. We suppose that ω-3 PUFA can alleviate early brain injury (EBI) via regulating necroptosis and neuroinflammation after TBI. This research intended to examine the neuroprotective effect of ω-3 and its possible molecular pathways in a C57BL/6 mice model of EBI caused by TBI. Cognitive function was assessed by measuring the neuronal necroptosis, neuroinflammatory cytokine levels, brain water content, and neurological score. The findings demonstrate that administration of ω-3 remarkably elevated neurological scores, alleviated cerebral edema, and reduced inflammatory cytokine levels of NF-κB, interleukin-1β (IL-1β), IL-6, and TNF-α, illustrating that ω-3 PUFA attenuated neuroinflammation, necroptosis, and neuronal cell death following TBI. The PPARγ/NF-κB signaling pathway is partially responsible for the neuroprotective activity of ω-3. Collectively, our findings illustrate that ω-3 can alleviate EBI after TBI against neuroinflammation and necroptosis.
Spatiotemporal Live-Cell Analysis of Photoreceptor Outer Segment Membrane Ingestion by the Retinal Pigment Epithelium Reveals Actin-Regulated Scission

Published: March 2023

The photoreceptor outer segment (OS) is the phototransductive organelle in the vertebrate retina. OS tips are regularly ingested and degraded by the adjacent retinal pigment epithelium (RPE), offsetting the addition of new disk membrane at the base of the OS. This catabolic role of the RPE is essential for photoreceptor health, with defects in ingestion or degradation underlying different forms of retinal degeneration and blindness. Although proteins required for OS tip ingestion have been identified, spatiotemporal analysis of the ingestion process in live RPE cells is lacking; hence, the literature reflects no common understanding of the cellular mechanisms that affect ingestion. We imaged live RPE cells from mice (both sexes) to elucidate the ingestion events in real time. Our imaging revealed roles for f-actin dynamics and specific dynamic localizations of two BAR (Bin-Amphiphysin-Rvs) proteins, FBP17 and AMPH1-BAR, in shaping the RPE apical membrane as it surrounds the OS tip. Completion of ingestion was observed to occur by scission of the OS tip from the remainder of the OS, with a transient concentration of f-actin forming around the site of imminent scission. Actin dynamics were also required for regulating the size of the ingested OS tip, and the time course of the overall ingestion process. The size of the ingested tip is consistent with the term “phagocytosis.” However, phagocytosis usually refers to engulfment of an entire particle or cell, whereas our observations of OS tip scission indicate a process that is more specifically described as “trogocytosis,” in which one cell “nibbles” another cell.SIGNIFICANCE STATEMENTThe ingestion of the photoreceptor outer segment (OS) tips by the retinal pigment epithelium (RPE) is a dynamic cellular process that has fascinated scientists for 60 years. Yet its molecular mechanisms had not been addressed in living cells. We developed a live-cell imaging approach to investigate OS tip ingestion, and focused on the dynamic participation of actin filaments and membrane-shaping BAR proteins. We observed scission of OS tips for the first time, and were able to monitor local changes in protein concentration preceding, during, and following scission. Our approach revealed that actin filaments were concentrated at the site of OS scission and were required for regulating the size of the ingested OS tip and the time course of the ingestion process.
