Abstract
To overcome the pollution to the environment with the application of flame retardants in automobiles, complete environment-friendly flame retardants have aroused wide concern. Furthermore, natural fibers have replaced artificial fibers in various fields due to their excellent performance and environmentally friendly. Thus, in this work, modified hemp fiber (HF-P) via phytic acid was obtained and used as a green flame retardant for automobile parts containing unsaturated polyester resins (UPR). The flame retardance of UPR composites were tested by thermogravimetric analysis, limiting oxygen index (LOI), and cone calorimeter test. A total of 3 wt% HF-P imparted UPR matrix excellent flame retardancy. The LOI value of UPR/HF-P-3 composites was increased from 18.9% of pure UPR to 22.1%, and the values of AHRR and THR were reduced to 401.9 kW/m2 and 150.6 MJ/m2, respectively. TGA test shows that HF-P can effectively improve the carbon-forming ability of UPR composites, which provides a material basis for condensed phase flame retardancy. For mechanical properties, the incorporation of HP-F endows a better enhancement on flexural strength of UPR composite.

Increasing the valency of motion verbs: the case of the portative construction
Authors: Messerschmidt Maria 
Published: April 2022

AbstractThis paper surveys the valency-increasing constructions that apply to motion verbs in 49 genetically diverse languages. These include causative constructions, a variety of applicative constructions and the portative construction which is a valency-increasing construction that is lexically restricted to motion verbs. In the portative construction, the verb’s valency is increased by adding theme as a P-argument, but conceptually there is also an element of (co-motional) causation. However, the paper argues that the construction is neither causative nor applicative. Instead, the portative construction, which is frequent in the sample languages, should be considered a distinct type of valency-increasing construction.

Abstract

Objectives
Osteoarthritis (OA) is a common degenerative disease of the joints. It has become one of the main diseases that cause the disability of the elderly in the world, and it has a severe impact on the quality of life of patients. It has been reported that miRNAs are involved the occurrence and development of OA. In the current work, we evaluated the effects of miR-22-3p on osteoarthritis in vivo and in vitro.

Methods
Confocal Laser Scanning Microscope (CLSM), flow cytometry analysis, indirect immunofluorescence (IFA) and Western-blot assays were performed to study the effect of miR-22-3p on osteoarthritis (OA).

Results
An LPS-induced osteoarthritis cell model was first constructed on C28/I2 cells (in vitro), and the model of mice OA was established by operation (in vivo). The results form RT-qPCR indicated that miR-22-3p expression was reduced by LPS (lipopolysaccharides) stimulation. Additionally, inflammatory cytokines and apoptosis-related markers were also obviously elevated with LPS treatment. Furthermore, up-regulation of miR-22-3p relieved the osteoarthritis in vivo and in vitro. Additionally, up-regulation of miR-22-3p obviously reduced the production of proinflammatory factors and cell apoptosis induced by LPS. Further research indicated that miR-22-3p may alleviate osteoarthritis by targeting inflammasome.

Conclusions
In conclusion, the upregulation of miR-22-3p could effectively alleviate osteoarthritis in vivo and in vitro, suggesting that miR-22-3p can be used to treat OA.

“Boquichico” Prochilodus nigricans es la especie más explotada por la flota pesquera comercial en la amazonia; como recurso, es de importancia alimenticia y socioeconómica a nivel regional. Dada a su importancia, el objetivo del estudio fue conocer sus características poblacionales en el río Ucayali, dando énfasis a los aspectos reproductivos, demográficos (estructura de tallas, edad y crecimiento). Se utilizaron ejemplares que sistemáticamente fueron obtenidas de manera mensual durante del año 2008 al 2013, de la pesquería comercial que desembarca en el puerto de Pucallpa (Ucayali). Se realizaron muestreos biológicos donde se registraron mediciones en cada ejemplar. Según los resultados obtenidos, la reproducción es de carácter estacional, ocurriendo el desove con intensidad en la transición a creciente (octubre a diciembre). Se estimó la talla de madurez (TM) de hembras en 23,5 cm LT (longitud total). La mayor proporción de hembras se observó en transición a vaciante (abril-junio), mientras que presentó diferencia a favor de los machos en transición a creciente (periodo de desove intenso). El análisis de la estructura de tallas mostró que el stock explotado estuvo compuesto por ejemplares cuyas tallas oscilaron entre de 10 a 36 cm LT. La talla media decaptura anual fue inferior a la TM en todos los años. La ecuación de crecimiento de von Bertalanffy definida por Lt = 36,2*[1-e (-0,31(t-0,51)] permite inferir que la especie es de rápido crecimiento y que podría vivir en teoría más de 9 años. Los peces exhibieron mejor robustez en los periodos de creciente (enero-marzo) ytransición a vaciante, donde los bosques inundados se convierten en hábitats óptimos para el desarrollo y crecimiento de la especie. La estacionalidad de las precipitaciones juega un rol clave para el éxito de la reproducción y el crecimiento de “boquichico” en el río Ucayali.

Strategies Subtitlers Use in Rendering English Slang Expressions Into Arabic
Authors: Hashish Ruba , Hussein Riyad F. 
Published: April 2022

Film translation has become a worldwide field in which subtitlers translate and transfer language and style from one culture into another. Subtitling has always been affected by cultural elements. The purpose of this study was to find out how professional subtitlers differ from fansubbers when dealing with such expressions concerning the strategies that both groups use to subtitle these expressions. To achieve the goals of this study, the researchers identified 120 slang expressions from two American movies, Goodfellas and Training Day, but chose only 30 slang expressions to report on how they were rendered by both groups. Results of the study showed that the professional subtitler and the fansubbers faced many challenges and used varying strategies when subtitling slang expressions. The challenges were related to the presence of some cultural terms and different types of slangs which are unfamiliar to most subtitlers. The most frequent strategies used by the professional subtitler and fansubbers were paraphrase, euphemism, omission, and calque. The study recommends that further studies be conducted on a larger sample of slang expressions in American or British movies and TV series. In addition, the subtitling of these slang expressions can be investigated in other target cultures and languages such as Spanish, Persian, Turkish, Greek, and Kurdish.

Published: April 2022

Background and Aims: In the current study, two bacteriophages were isolated from the wastewater sources and characterized by lytic activity against the Listeria monocytogenes (L. monocytogenes) bacterium.
Materials and Methods: 50 wastewater samples were collected from the disposal sites. The phages were isolated from the treated samples using the double agar overlay method with L. monocytogenes as the host bacterium. Plaque morphology, temperature, pH, titration of phage lysate, host range, and scanning electron microscopic morphology were used to characterize the isolated phages.
Results: Bacteriophage was found in two samples taken from wastewater treatment plants. Phages were proliferated and released under optimal bacterial growth conditions at pH 7; 37 °C in 36-hour incubation. A 10:1 ratio of bacterial cells to phage produced the greatest lytic ability. The highest phage titrated under optimal conditions was estimated at 9×109 pfu/ml. The scanning electron microscopic image revealed a bacteriophage morphology corresponding to the head and tail group. The host range observations demonstrated that L. monocytogenes were unique to the isolated phage. The elimination of L. monocytogenes growth in milk and whey samples revealed that this bacteriophage targeted bacteria and resulted in a 75% reduction in bacterial contamination.
Conclusion: The results suggest that the phages obtained from L. monocytogenes may be utilized to combat this pathogen in dairy, agri-food, wastes, and other associated infections.
Molecular and Clinical Characterization of 7 Iranian Patients with Severe Congenital Factor V Deficiency: Identification of 4 Novel Mutations

Published: April 2022

Background and Aims: Congenital factor V (FV) deficiency is a rare bleeding disorder with 1 in 1000000 persons in the general population. Individuals with FV activity <1% and very low FV antigen levels are characterized as severe FV deficient patients. Little data is available about the molecular basis of this bleeding disorder in Iran.
Materials and Methods: We analyzed 7 unrelated Iranian FV deficient patients regarding clinical manifestation and genotype. The molecular dynamic simulation was carried out to analyze the effect of novel mutations on the FV structure.
Results: All cases had recurrence epistaxis, oral cavity bleeding, and hematoma were frequent in our patients. The molecular analysis led to the identification of three already reported mutations (IVS 19+3 A>T, 4014-4017 del TCAG and p.P419R) and four novel mutations (IVS9-1 G>C, Y478D, L1844P, I1556T) in the FV gene of our patients. According to the molecular modeling results, it seems that in the two mutations Y478D and I1556T, an increased number of H-bonds in mutant proteins compared to natural ones reduces the flexibility and increases the stability of the mutant proteins. The results also show that in L1844P and I1556T mutations, the total solvent accessible surface area (both hydrophilic and hydrophobic) significantly decreases compared to the natural variants.
Conclusion: Identifying the causative mutation in patients with FV deficiency helps to determine the molecular basis of this bleeding disorder and gain more insight into explaining the variable clinical manifestations of patients with FV deficiency.

Published: April 2022

Background: The current research seeks to present a comparative study of the effect of filgrastim and pegfilgrastim in the treatment of fever and neutropenia in leukemia patients.
Materials and Methods: The present study is a blind randomized clinical trial. The study population is comprised of 120 children with acute lymphoblastic leukemia (ALL) who were admitted to the hospital due to mild febrile neutropenia during 2019. Included patients were divided into two groups. Filgrastim (10 micrograms/ kilogram, daily subcutaneously) and pegfilgrastim (100 micrograms per kilogram of a subcutaneous dose) were used for groups, respectively. Fever monitored every 6 hours, and neutrophil count was performed every 48 hours. The questionnaire designed in the study included age, type of drug side effects, number of days of neutropenia, and fever cessation time. Then, the data were analyzed by SPSS software.
Result: Leukemic children with fever and neutropenia (N=120) were included in the study, which was 59 (49.1%) male and 61 (50.9%) female by the mean age of 79±44 months. The mean days of neutropenia correction in the filgrastim and pegfilgrastim groups were 5 and 4 days, respectively, which was not significantly different (p =0.08). There was no correlation between patients’ complications and types of treatments (p>0.05). Muscular pain was the most common complication observed among 4 cases and 1 case following filgrastim and pegfilgrastim administration, respectively. Furthermore, hyperleukocytosis following pegfilgrastim consumption was observed in two cases.
Conclusion: There was no significant correlation between the duration until the cessation of fever and the number of neutropenia days in the two groups receiving pegfilgrastim and filgrastim. Therefore, the fever and neutropenia improve with pegfilgrastim earlier than filgrastim; besides, fewer injections, patient comfort, and less musculoskeletal pain can be observed.

Background: This study aimed to assess cutoff of ferritin for evaluation of osteoporosis in patients with Thalassemia Major (TM).
Materials and Methods: This analytic cross-sectional study was conducted in17 Shahrivar children's hospital, Rasht, Iran, from November 2017 to November 2018. The inclusion criteria were indicated as the presence of TM in patients aged 12-19 years old with records of their regular visits. The exclusion criteria were noted as the presence of any chronic bone diseases such as osteomalacia or osteogenesis imperfecta, delayed puberty, hypothyroidism, parathyroid dysfunction, renal failure, liver failure, and growth hormone deficiency. Ferritin level was assessed, and bone densitometry was performed for all patients with TM.
Results: In this study, 53 females (54.6%) and 44 males (43.4%) were enrolled. Results showed that 36 (37.1%), 49 (50.5%), and 12 (12.4%) patients had a normal bone density, osteopenia, and osteoporosis, respectively. Comparing these three groups showed that despite higher mean serum level of ferritin in TM patients with osteoporosis than patients with osteopenia and normal bone density, no significant statistical difference was noted in these three groups (P >0.05). Besides, the mean ferritin level in patients with abnormal bone densitometry (osteopenia and osteoporosis) was higher than in patients with normal ones. A significant difference was noted between abnormal and normal densitometries (p=0.03). The Area under the Curve for ferritin was 0.708, and the cutoff point was indicated for ferritin was 2006 ng/ml.
Conclusion: Regarding the results, there was a high frequency of osteoporosis and osteopenia in teenagers with TM. As bone density abnormality formation is time-consuming, and prevention is the primary strategy for management, it is highly recommended to assess bone mineral density regularly starting from early childhood.

Published: April 2022

Background: Sleep habits may play a role in the onset of sleep disorders. Several factors affect sleep habits. This study aimed to investigate sleep habits and related factors in childhood cancer survivors (CCS).
Materials and Methods: This cross-sectional study was performed on 400 children (age range: 5-15 years) who recovered from cancer in Tehran, Iran, in 2020. A 35-item Children's Sleep Habits Questionnaire (CSHQ) was used to determine children’s sleep habits. Correlation coefficient test, independent t-test, and one-way analysis of variance (ANOVA) were used to determine the correlation between results.
Results: Participants’ mean age was 10.45± 12.3 years (49% males vs. 51% females). The mean total score of the CSHQ was 58.53±7.8. There was a negative and significant relationship between age and the total score of CSHQ (P=0.009). Independent t-test showed that the subscales and the total score of the CSHQ were not significantly different between males and females (P=0.834). There was no significant relationship between the total score of the CSHQ and the duration after recovery (P=0.08).
Conclusions: The CCS are at higher risk of sleep disorders and the possibility of sleep disorders is higher in younger patients. Girls and boys who have survived cancer are equally prone to sleep disorders. There is a possibility of developing sleep disorders at any time during the recovery period. Factors such as the family’s socioeconomic status, level of physical health, duration of cancer, and the age of the children should be considered when assessing and treating sleep problems in CCS.

Authors: Ramos Stephen , Guerra Winifred , Bois Steff Du 
Published: April 2022

Introduction: Full-service sex workers (FSSWs) are relatively prevalent in the U.S. and are known to face criminalization, stigma, and other factors relating to poor health. The main aim of this study was compare the mental and physical health of full-service sex workers in the United States in 2019-2020
Methods: In this prospective cohort study, participants were recruited through national community samples from U.S.-based FSSW advocacy and community organizations. Data were collected from November 2019 to February 2020. The study sample (n=83) included mostly of the white (81.9%), cisgender females (66.3%), who were relatively young (28.01 [4.25]), and identified as a sexual minority (57.8%). Participants completed an online survey on mental (e.g., depression, anxiety) and physical (e.g., sleep, fatigue) health, using the patient-reported outcomes measurement information system (PROMIS-29). Mean (SD) and Frequency (%) were used for description and for data analysis z-tests in SPSS version 27 with 5% significant level were used.
Results: The sample of FSSWs reported significantly poorer health in all health domains compared to the U.S. general population reference indices. FSSWs showed higher levels of depression (p <.001), anxiety (p <.001), fatigue (p <.001), sleep difficulties (p <.001), lower levels of physical functioning (p <.001) and the ability to participate in social activities (p =.03) compared with the U.S. reference indices.
Conclusions: FSSWs experience significant mental and physical health disparities compared to general population. the need for further investigation of the social-ecological determinants of health for members of this marginalized community, many of whom are known to face health inequities.
