Published: June 2022

The object of the study is a probiotic Rumit produced by Biotrof Ltd., which can be added to the diet of milk-fed calves. It is developed on the basis of cellulolytic bacteria. In order to assess the effectiveness of the probiotic use there has been conducted a scientific and agricultural experiment on the basis of the agricultural production co-operative Kolkhoz Andoga of the Kaduysky district, Vologda region since March to June 2021. Studied were 20 calves of black-and- white bred aged 1.5-2 months divided according to the principle of paired peers into two groups: a control and an experimental. The experimental group was given the probiotic Rumit in the amount of 15 g/head/day during 90 days as a supplement to the basic diet. The data on live weight obtained in the course of the study indicate that the use of the probiotic in feeding calves has led to an increase in gross growth to 74.2 kg, that has provided a 3.8 % reduction in feed costs per unit of output.

Authors: Rubio alcala Fernando david , Cano Jiménez Pablo Antonio
Published: June 2022

This paper describes the development and standardization of a measure of self-esteem in the foreign language classroom. The reliability and validity of self-esteem in the foreign language classroom scale (SEFLS) were determined for a sample of 252 Spanish native speakers studying a foreign language. The test reliability coefficient was ω= ,92. Confirmatory factorial analysis (CFA) yielded a 10-item three-dimension structure acceptable model fit. The three dimensions were language competence, skills performance and perceived social support. The SEFLS measure could be a useful tool for assessing students’ self-esteem in the foreign language classroom. Implications, limitations, and directions for future organizational research are discussed.
A study on interdisciplinary teaching practices: Primary and secondary education curricula
Authors:   Faculty of Education, Pamukkale University, Denizli, Turkey, Kanmaz Ahmet
Published: June 2022

This study addresses the views of teachers about the benefits of interdisciplinary teaching practices in primary and secondary school education curricula, the level of the use of interdisciplinary approach and the place of interdisciplinary approach in the curriculum. The study seeks to examine the views of teachers about the interdisciplinary approach and their level of use of this approach in primary and secondary education curricula. To this end, the explanatory mixed design was employed in the study. A descriptive scanning model was employed for the quantitative dimension of the study. In the quantitative dimension, the phenomenological method was used. The Interdisciplinary Teaching Approach Questionnaire was utilized to gather quantitative data, and qualitative data were gathered through a semi-structured interview form. The sample of the research is composed of 413 classroom and branch teachers working in official primary and secondary schools in the central districts of Denizli. Consequentially, it can be argued that teachers have positive views on the interdisciplinary approach. Further, the teachers found the interdisciplinary approach relatively useful, however, they did not effectively implement it in in-class activities as this approach was not sufficiently incorporated into the curriculum. Teachers' views on the interdisciplinary approach differed by the variables of professional seniority and teaching level, whereas the gender variable was not found to be a significant predictor.
Repensar, Re materializar y Autoconstruir: Una alternativa proyectual y productiva para el habitar
Authors: Aceto Diego Martin , Benítez Daiana Marisol
Published: June 2022

La Investigación problematiza la relación entre autogestión y Derecho a la Ciudad a partir de la identificación de marcos de oportunidad y limitaciones que se presentan en la construcción del hábitat. La primera comprendida como lógica, practica y organización colectiva de producción de bienes para el habitar, que emerge con variaciones y dificultades socioeconómicas; la segunda, en términos de sus niveles de concreción como pleno acceso a la centralidad urbana (objetiva y simbólica). 

En este sentido, creemos que abordar la complejidad material, desde nuestra disciplina, implica reflexionar sobre las interpretaciones constructivas actuales desde una mirada que resignifique la autoconstrucción como una solución sustentable al déficit de vivienda.

Authors: Defagó Maria Daniela , Eynard Aldo Renato
Published: June 2022

Introducción: A partir de la nutrigenética, estudio del efecto que la variación genética tiene sobre la respuesta individual a la dieta, es posible comprender y modular la respuesta clínica condicionada por el genotipo por la dieta.
Objetivo: explorar la evidencia bibliográfica sobre los potenciales de la nutrigenética en el abordaje y tratamiento de las enfermedades cardiovasculares (ECV) y factores de riesgo asociados.
Materiales y métodos: se realizó una búsqueda sistemática de publicaciones en bases de datos electrónicas MEDLINE, EMBASE y Google Scholar. Se incluyeron aquellos artículos que contenían las palabras claves o una combinación de ellas, durante 1990-2019, tanto de estudios experimentales como observacionales.
Resultados: 49 artículos fueron incluidos, clasificados de acuerdo a las principales vías moleculares involucradas en la etiopatogenia de las ECV. Si bien se encontró una amplia diversidad de variantes genéticas que confieren susceptibilidad para las ECV y factores de riesgo como obesidad, dislipemia e hipertensión arterial, se observó poca consistencia en la publicación de estudios de replicación.
Conclusiones: el conocimiento de variantes genéticas permite la personalización de la dieta, que puede complementarse con otras recomendaciones saludables asociadas al estilo de vida. Son necesarios más estudios en grandes poblaciones y metaanálisis que muestren de manera inequívoca la relación gen-nutriente.

Authors: Vaccaro Carlos , Gonzalez Marcos , Ruffa Tatiana , Campana Juan Pablo , Mentz Ricardo , Poggi Catalina , Rubinstein Fernando , Marcello Peter
Published: June 2022

INTRODUCCIÓN: La cirugía colorrectal laparoscópica mano asistida (CLMA) es un abordaje alternativo a la laparoscopia directa (LD) que requiere de un dispositivo específico para mantener el neumoperitoneo. Nuestro grupo describió una técnica original de doble guante como alternativa a este dispositivo. El objetivo del presente trabajo fue analizar los resultados de esta técnica comparándola con la técnica de LD. 
MÉTODOS: Se analizó una serie consecutiva de pacientes sometidos a cirugías colorrectales laparoscópicas entre 2004 y 2020 en el Hospital Italiano de Bs, As, Argentina. Se realizó un modelo de regresión múltiple de selección progresiva y apareamiento por puntaje de propensión para analizar los resultados perioperatorios.
RESULTADOS: Los casos de CLMA (n=458) y LD (n=1692) fueron demográficamente similares. CLMA se asoció a un menor tiempo operatorio (170,3 vs 206,9 minutos, p<0.001). Dicha reducción fue más marcada en obesos (44.1 min), pacientes grandes (37.5 min), cirugías complejas (33.8 min) y en procedimientos realizados por cirujanos no entrenados (57,6 vs 31,6 minutos, p<0.001). CLMA resultó tener menor índice de conversión (5% vs 9.9%, p<0.001) con una razón de probabilidades ajustada de 0,45. No se hallaron diferencias en cuanto a estadía hospitalaria, morbimortalidad y readmisión.
CONCLUSIÓN: CLMA con doble guante es comparable a la LD manteniendo un tiempo operatorio reducido y bajo índice de conversión, particularmente en pacientes obesos sometidos a procedimientos complejos.

Published: June 2022

Background: Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is a hereditary disease characterized by fibrofatty infiltration of the right ventricular myocardium that predisposes affected patients to malignant ventricular arrhythmias, dual-chamber cardiac failure and sudden cardiac death (SCD). The present study aims to investigate the risk of detrimental cardiovascular events in an Asian population of ARVC/D patients, including the incidence of malignant ventricular arrhythmias, new-onset heart failure with reduced ejection fraction (HFrEF), as well as long-term mortality. Methods and Results: This was a territory-wide retrospective cohort study of patients diagnosed with ARVC/D between 1997 and 2019 in Hong Kong. This study consisted of 109 ARVC/D patients (median age: 61 [46–71] years; 58% male). Of these, 51 and 24 patients developed incident VT/VF and new-onset HFrEF, respectively. Five patients underwent cardiac transplantation, and 14 died during follow-up. Multivariate Cox regression identified prolonged QRS duration as a predictor of VT/VF (p < 0.05). Female gender, prolonged QTc duration, the presence of epsilon waves and T-wave inversion (TWI) in any lead except aVR/V1 predicted new-onset HFrEF (p < 0.05). The presence of epsilon waves, in addition to the parameters of prolonged QRS duration and worsening ejection fraction predicted all-cause mortality (p < 0.05). Clinical scores were developed to predict incident VT/VF, new-onset HFrEF and all-cause mortality, and all were significantly improved by machine learning techniques. Conclusions: Clinical and electrocardiographic parameters are important for assessing prognosis in ARVC/D patients and should in turn be used in tandem to aid risk stratification in the hospital setting.
Efficacy and Safety of a Polytetrafluoroethylene Membrane Wrapped a Single Layer of Sirolimus-Eluting Stent in a Porcine Coronary Perforation Model
Authors: Liu Yi , Zhou Jingyu , Wang Xiaoming , Gao Chao , Mou Fangjun , Yang Wangwei , Wang Rutao , Tao Ling
Published: June 2022

Background: Covered stents are effective in treating coronary artery perforation (CAP), however, the high rate of immediate device deployment failure and in-stent restenosis have limited the application of the currently covered stents. Methods: We designed a covered stent system consisting of a single layer of drug-eluting stent and a layer of polytetrafluoroethylene (PTFE) membrane wrapped at the outer layer of the stent. The immediate sealing effect of our novel covered stent was observed by using an Ellis type III CAP model. The device’s success was defined as its ability to seal the perforation, assessed by visual estimation and final thrombolysis in myocardial infarction (TIMI) 3 flow. The antiproliferative effect was evaluated in 12 swine, which were randomly assigned to treatment (sirolimus-eluting covered stents) and control (bare metal covered stents) groups. Coronary angiography and optical coherence tomography (OCT) were performed at index procedure, 1- and 6-month after stent implantation. All swine were sacrificed for histopathological analyses at 6-month. Results: The device success rate was 100%. All swine were alive at 6-month follow-up. At 1-month, the treatment group had a larger minimal luminal diameter (MLD) (1.89 ± 0.29 mm vs. 0.63 ± 0.65 mm, p = 0.004) and lower late luminal loss (LLL) (0.47 ± 0.15 mm vs. 1.80 ± 0.34 mm, p < 0.001) compared with control group. At 6-month, the treatment group had a numerically higher MLD (0.94 ± 0.75 mm vs. 0.26 ± 0.46 mm; p = 0.230) and lower LLL (1.43 ± 0.85 mm vs. 2.17 ± 0.28 mm; p = 0.215) compared with control group. Histological analyses revealed the mean plaque area was lower in the treatment group (2.99 ± 0.81 mm2 vs. 4.29 ± 0.77 mm2, p = 0.035) than in the control group. No in-stent thrombosis was observed in either group. Conclusions: In the porcine model of coronary perforation, the PTFE membrane wrapped sirolimus-eluting stent showed a high device success rate in sealing the perforation. The drug-eluting covered stent demonstrated a relatively sustained antiproliferative effect up to 6 months post-implantation.

Published: June 2022

Background: An increasing number of coronary heart disease (CHD) patients with an aging population are demanding available and effective out-of-hospital continuous healthcare services. However, great efforts still need to be made to promote out-of-hospital healthcare services for better CHD secondary prevention. This study aims to evaluate the effectiveness of a hospital-community-family (HCF)-based integrated healthcare model on treatment outcomes, treatment compliance, and quality of life (QoL) in CHD patients. Methods: A quasi-randomized controlled trial was conducted at the Department of Cardiology, a tertiary A-level hospital, Wuhan, China from January 2018 to January 2020 in accordance with the Consolidated Standards of Reporting Trials guidelines. CHD patients were enrolled from the hospital and quasi-randomly assigned to either HCF-based integrated healthcare model services or conventional healthcare services. The treatment outcomes and QoL were observed at the 12-month follow-up. Treatment compliance was observed at the 1-month and 12-month follow-ups. Results: A total of 364 CHD patients were quasi-randomly assigned to either integrated healthcare model services (n = 190) or conventional healthcare services (n = 174). Treatment outcomes including relapse and readmission rate (22.6% vs 41.9%; relative risk [RR] = 0.54; 95% confidence interval [CI], 0.40–0.74; p = 0.0031), the occurrence of major cardiovascular events (19.5% vs 45.4%; RR = 0.43; 95% CI, 0.30–0.59; p = 0.0023), complication rate (19.5% vs 35.0%; RR = 0.56; 95% CI, 0.39–0.79; p = 0.0042), and the control rate of CHD risk factors (p < 0.05, average p = 0.009) at the 12-month follow-up in the intervention group were better than those of the control group. There was no significant difference in treatment compliance at the 1-month follow-up between groups (p > 0.05, average p = 0.872). Treatment compliance at the 12-month follow-up in the intervention group, including correct medication, reasonable diet, adherence to exercise, emotional control, self-monitoring, and regular re-examination, was higher than that of the control group (p < 0.05, average p = 0.007). No difference was found in the compliance with smoking cessation and alcohol restriction at the 12-month follow-up between groups (p = 0.043). QoL at the 12-month follow-up in the intervention group was better than that of the control group (86.31 ± 9.39 vs 73.02 ± 10.70, p = 0.0048). Conclusions: The integrated healthcare model effectively improves treatment outcomes, long-term treatment compliance, and QoL of patients, and could be implemented as a feasible strategy for CHD secondary prevention.
The Colt Device for Treating Thoraco-Abdominal Aneurysms - Concept and Clinical Results
Authors: Szopiński Piotr , Pleban Eliza , Iwanowski Jarosław
Published: June 2022

Objective: To report results of application a new stent graft design for the treatment of patients with thoraco-abdominal aneurysms (TAAAs), which was co-invented by a vascular surgeon. This is a retrospective observational study. Methods: The Colt is a self-expanding stent graft, composed of nitinol metal stents creating a special exoskeleton with asymmetric springs covered with polyester material. The Colt device offers some advantages over existing stent graft options. The main body is available in two different diameters on both ends and in three different lengths. It has four branches pointing downward and coming from the main stent graft at two levels. It offers the physician an opportunity to decide which branch to choose for the target vessel. It may be implanted alone or extended proximally and distally. Balloon expandable and/or self-expanding stent grafts are used to create the visceral branches. In complex extensive aneurysms, the procedure is divided into two or three stages to minimize the risks of spinal cord ischemia. Results: Between August 2015 and December 2021, twenty-two Colt stent grafts were implanted in twenty males and two females (aged 56–81) with TAAAs (eight Type II; twelve Type III; two Type IV). The mean aneurysm diameter was 73.4 mm (range 64–83). All patients were asymptomatic. Eighty-five target vessels were reconstructed using either self-expanding or balloon-expandable stent grafts. Fourteen bifurcated, six custom-made tubes and two aortouniiliac (AUI) stent grafts were used as distal extensions to the Colt device. Completion angiography revealed no type I endoleaks. Five patients had Type II endoleaks which were treated conservatively. There were no intraoperative deaths. One patient died on the 7th postoperative day from multiorgan failure. We did not observe any other complications within 30 days after implantation. One patient died from Covid-19 two months after discharge. Follow-up ranged from three to 75 months. There was no migration or dislocation of the docking station or proximal and distal extensions. All Colt device prostheses remained patent, however, two branches leading to the coeliac trunk were found occluded at the time of the 12-month CTA, without any symptoms. In two patients, there were late problems with three renal bridging stent grafts. One of the Type II endoleaks resolved spontaneously after one year, while four others remain under observation. No patient had an increase in sac diameter. Conclusions: Results from the current series are promising. The Colt stent graft can be applied to a large variety of TAAA anatomies, which may facilitate the development of new “off-the-shelf” devices in the future.

Due to the youth of the cryptocurrency sphere, the logic of interaction between investors, users and protocols is not always precisely defined. Analysis of the impact of ESG on cryptocurrencies proves that the demand for bitcoin network capacity (occupies the main market share) is the main factor in predicting the price of this cryptocurrency and the cryptocurrency market as a whole. The choice of the statistical method of analysis is determined by the purpose of statistically justified determination of the relationship of the data under consideration, and the reliability of the analysis is checked using Fischer and Student tests. In this paper, several innovations are proposed to solve the problem of energy dependence of cryptocurrencies: firstly, the analysis of cryptocurrencies in the paradigm of sustainable development (taking into account the consumption of a huge amount of energy for the functioning of cryptocurrency systems); secondly, feedback logic to explain the interaction of subjects, including the following parties: users, developers, network infrastructure and their interaction; thirdly, statistical analysis with the creation of artificial variables from real data and iterative improvement of the model. This paper proves that sustainable cryptocurrency growth is impossible when viewed from the perspective of “Green Economics” by Molly Scott Cato. The author's approach is relevant compared to other methods of linear transformations for creating artificial variables by selecting data using the VIF test. As a result, several versions of models were obtained using various combinations of the initially proposed factors, on the basis of which the nature of the greatest influence on the price of bitcoin was established in the form of technical factors and energy infrastructure needs.

Differential expression of tripartite motif-containing 11 in cancers of the breast.
Authors: Mamoor Shahan
Published: June 2022

Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with early-onset breast cancer. We found significant differential expression of the gene encoding tripartite motif-containing 11, TRIM11, when comparing primary tumors of the breast to the tissue of origin, the normal breast: in women aged 45 and younger, and women aged 70 and higher. TRIM11 mRNA was present at significantly higher quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of TRIM11 in primary tumors of the breast was correlated with overall survival in patients with HER2+ subtype breast cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by PAM50 molecular subtype. TRIM11 may be of relevance to initiation, maintenance or progression of cancers of the female breast.

Early marriage is a social event that still occurs in many areas. An early marriage includes being part of the problems or issues that are very important today. Because many people whose age is less than the rules specified in the law, but still carry out the early marriage. Marriage has a very important meaning and position in the order of human life. Because with marriage, a bond of association can be formed between two people of the opposite sex officially in a husband and wife bond into a family. Furthermore, the family can continue to develop into a community group. In this study, the aim is to determine the public's understanding of early marriage and to discuss the factors and their various impacts with the existence of these problems. The method used in this research is a qualitative method, while if it is seen from the type of research, it is library research (field research). Thus, the result of this research is that the existence of early marriage is due to certain factors, which depend on each person and do not see what the impact will be after doing this.

Authors: Rambo-Hernandez Karen E , Brigandi Carla , Amin Syahrul , Spillane Nancy
Published: June 2022

This study illustrates the consequences of accounting for or ignoring teacher variability in student ratings in conjunction with combination rules when identifying students for gifted services in one rural primary school. Teachers (n = 16) rated 282 first and second grade students on creativity, motivation, mathematics, and science. Results indicated the most variability in how teachers used the science scale and the least variability in the mathematics scales. Further, teachers rated female students higher than male students in motivation, but not on any other scale. More students were identified if the top students were identified in each class versus the top students in each grade level, and largely, the students who were identified within their classrooms were not the same students who were identified within their grade level. And as expected, OR rules resulted in the highest number of students identified. Implications and recommendations are discussed.

Dinamika perkembangan koperasi selain dipengaruhi oleh politik juga dipengaruhi oleh undang-undang perkoperasian. Melalui undangundang koperasi ditentukan hidupnya. Undangundang perkoperasian yang dibentuk juga terikat dan terpengaruh oleh kondisi ideologi politik dan ekonomi pada zamannya. Makalah ini berjudul hubungan pemerintah dengan gerakan koperasi bertujuan utuk mengetahui bagaimana tahapan dini pertumbuhan koperasi melalui aspek hukum dan mengetahui bagaiman sikap Negara-negara dunia terhadap gerakan koperasi. Teknik pengambilan data dalam penyusunan karya tulis ini menggunakan metode studi kepustakaan dan riset terhadap jurnal-jurnal di google. Perundang- undangan ini ada yang bediri sendiri dan langsung mengatur koperasi di Negara yang bersangkutan, tetapi ada yang hanya dititipkan permasalahan koperasi kedalam perundan- undangan yang lain. Dalam perkembangannya meskipun pemerintah dimasing – masing Negara telah membuat undang- undang tentang perkoperasian, dalam praktiknya terdapat perbedaan dalam sikap pemerintah terhadap gerakan koperasi di masing- masing Negara
KELEMBAGAAN & IDENTITAS KOPERASI
Authors: Zahra Sufiani
Published: June 2022

Koperasi merupakan lembaga ekonomi yang cocok diterapkan di Indonesia. Karena sifat masyarakatnya yang kekeluargaan dan kegotongroyongan, sifat inilah yang sesuai dengan azas koperasi saat ini. Sejak lama bangsa Indonesia telah mengenal kekeluargaan dan kegotongroyongan yang dipraktekkan oleh nenek moyang bangsa Indonesia. Kebiasaan yang bersifat nonprofit ini, merupakan input untuk Pasal 33 ayat 1 UUD 1945 yang dijadikan dasar/pedoman pelaksanaan Koperasi. Kebiasaan-kebiasaan nenek moyang yang turuntemurun itu dapat dijumpai di berbagai daerah di Indonesia di antaranya adalah Arisan untuk daerah Jawa Tengah dan Jawa Timur, paketan, mitra cai dan ruing mungpulung daerah Jawa Barat, Mapalus di daerah Sulawesi Utara, kerja sama pengairan yang terkenal dengan Subak untuk daerah Bali, dan Julo-julo untuk daerah Sumatra Barat merupakan sifat-sifat hubungan sosial, nonprofit dan menunjukkan usaha atau kegiatan atas dasar kadar kesadaran berpribadi dan kekeluargaan. Bentuk-bentuk ini yang lebih bersifat kekeluargaan, kegotongroyongan, hubungan social, nonprofit dan kerjasama disebut Pra Koperasi. Pelaksanaan yang bersifat pra-koperasi terutama di pedesaan masih dijumpai, meskipun arus globlisasi terus merambat kepedesaan.

Participation in an indigenous Amazonian led ayahuasca retreat associated with increases in nature relatedness – a pilot study
Authors: Ruffell Simon , Gandy Sam , Tsang WaiFung , Netzband Nigel , Hollingdale Jack
Published: June 2022

Indigenous Amazonian shamanic ayahuasca practice is deeply rooted in nature and it is employed as an ecological mediating agent and in collective environmental decision-making processes by some of the groups that use it. Phenomenologically, the ayahuasca experience is often rich in nature-based themes and content, and its usage has been associated with eliciting shifts in perspectives and attitudes towards nature. In this proof of concept study, participation in an ayahuasca retreat in a traditional indigenous Amazonian context (with a mean of 5.85 ceremonies attended) was associated with significant increases in nature relatedness (n = 24; Cohen’s d = .51) and mindfulness (n = 38; Cohen’s d = .75), and improvements in depression (n = 47; Cohen’s d = 1.18), state anxiety (n = 47; Cohen’s d = 1.02), and trait anxiety (n = 42; Cohen’s d = .88). Furthermore, significant negative correlations were found between changes in nature relatedness and depression (r = .623, p = .001), state anxiety (r = -.542, p = .008), and trait anxiety (r = -.485, p = .022), with a significant positive correlation between change in nature relatedness and mindfulness (r = .747, p = .001). It is currently unclear if the changes seen were due to consumption of the brew, participation in ceremony, or the retreat setting itself. Although this pilot study suggests a potential therapeutic role for Amazonian ayahuasca retreats as a multidimensional intervention, further work is required to assess the role of possible mediators underlying such shifts, while evaluating to what extent these are sustained long-term.

Zeolite has been synthesised from rice husk ash (RHA) without pretreatment to make use of cheap and readily available by-products in Vietnam. The parameters affecting the adsorption process such as pH, the concentration of MB, adsorbent dose, and contact time were specifically investigated. In addition, the adsorption isotherm models such as Langmuir, Freundlich, Dubinin - Radushkevich, pseudo-first-order kinetic, and pseudo-second-order kinetic were performed. The results showed that the maximum adsorption capacity and efficiency of NaX on MB were 16.67 mg/gand 87.03%, respectively, at pH 8, MB concentration of 15 mg/l, adsorbent dose of 0.05 g, and contact time of 30 min. The adsorption of MB by NaX has followed the Freundlich model and was physical adsorption fitted to pseudo-second-order kinetic. Zeolite NaX was reused four times with a decrease of adsorption yield by 24.03%. This study reveals the potential application of NaX on the removal of organic dyes and future researches on the removal of heavy metals or gases.

Male infertility is a disease that affects men’s fertility caused by various factors including genetic abnormalities, and immunological or endocrine diseases. Several studies have demonstrated the correlation between DNAH1polymorphisms and the risk of having male infertility. To assess the association of DNAH1 rs12163565 with male infertility, we extracted total DNA from whole blood of 213 Vietnameses, including 110 patients with male infertility and 103 healthy controls. The genotypes of the polymorphism were determined by PCR-RFLP method. The distribution of genotypes and their relationship with male infertility were analyzed by statistical methods. The results indicated that DNAH1 rs12163565 followed Hardy-Weinberg equilibrium (p>0.05). However, no association was established between the polymorphism and male infertility in the three models (additive, dominant, and recessive) (p>0.05). This study would provide the knowledge about the association of DNAH1with male infertility in Vietnamese population.

The average concentration of 16 PAHs in street dust in Hanoi (n=27) was 1,226 ng/g, ranging from 532 to 2,276 ng/g. The total toxic equivalent amount of 16 PAHs, in comparison with BaP, TEQBaP was 121.58 ng/g on average and varried in a range of 35.36 and 322.22 ng/g. Amongst 16 analysed PAHs, the most abundant compounds were Pyr (16.4%)>BbF (14.0%)~Fluth (14.0%)>BghiP (12.3%)>Phe (7.9%). However, BaP occupied up to 52.6% of the toxic equivalent amount, followed by DahA (15.9%) and BkF (14.2%). In Hanoi street dust, the ratios of some special PAHs such as Fluth/Fluth+Pyr (0.46±0.04); BaA/Chr in a range of 0.27-0.49 (occupied 60% of the dust sample amount), and IcdP/BghiP (0.40±0.11), showed that the main emission source of PAHs in Hanoi road dust was from traffic vehicles using gasoline. The PAHs concentrations in street dust in Hanoi tended to be reduced up to approximately 10% in the observation for a few recent years despite the increasing traffic vehicle volume of the city. That means the better traffic vehicles and road management in Hanoi, the lesser emission of toxic organic pollutants, especially PAHs, to the ambient air.

In this study, irradiation technique was used to produce copolymer AAc-g-PVP with different ratios of acrylic acid (AAc) and polyvinyl pyrrolidone (PVP). The results showed that copolymer hydrogel with AAc/PVP ratio 3:1 (w/w) had the highest gel content (94.88%) and water swelling degree was found to be 4 g/g at an adsorbed dose of 20 kGy. The ability to adsorb Pb2+, Cu2+, Mn2+,and Cd2+ ions of copolymer have been carried out. Results on adsorption isotherm models show that the adsorption of ions of the copolymer is consistent with the Langmuir adsorption model with a high correlation coefficient (R2>0.99). The maximum adsorption capacities are 244, 222, 167, and 170 mg/g for Pb2+, Cu2+, Mn2+, and Cd2+, respectively. The AAc-g-PVP copolymer hydrogel material has potential applications for adsorbing heavy metal ions in water.

The colloidal solutions of selenium nanoparticles (SeNPs) stabilised in water-soluble β-glucan were successfully prepared by the gamma ray (Co-60) irradiation method. The saturation dose for complete reduction of solutions contained 40, 60, 80, 100, and 120 ppm Se4+ were determined at 4, 6, 8, 10, and 12 kGy, respectively. The structural characteristic and particle size were analysed by Fourier transform infrared spectrophotometer (FTIR) and Dynamic light scattering (DLS). The obtained results showed that the increase of β-glucan concentration from 1 to 4% or pH of sample from 5 to 10 caused a slight change of particle size but strongly affected the particle size distribution in the product. The particle size of the product was almost unchanged after 60 days stored at 0 and 4oC conditions, but a slight increase was observed in the sample stored at room temperature after 30 days. In addition, the antioxidant activity of SeNPs/β-glucan was much higher than that of vitamin C at the same tested concentration and this activity was increased by the increase of reaction time. The smaller particles size in the product displayed the higher antioxidant activity. These results indicated that SeNPs/β-glucan prepared by irradiation method is a very promising product for application in the fields of cosmetic and functional food.

Light scattering due to the interaction of photons and acoustic waves present in a dilute inert gas is analyzed through the use of irreversible thermodynamics. The dispersion relation, which governs the dynamics of the density uctuation of the gas allows the establishment of a simple criterion for the corresponding Rayleigh-Brillouin spectrum to be observed. The criterion here proposed allows a clear physical interpretation and suggests generalizations for other interesting physical scenarios.

Plyometric training (PT) is a very popular form of physical conditioning for healthy individuals that have been extensively studied over the last decades. The study aimed to determine the effect of PT on improving vertical jump (VJ) in female footballers (14-17 years old). The study adopted a pretest-posttest quasi-experimental design. The study population was the female football players of the National Women's Football League in Algeria (LNFF). Twenty-two players were drawn from the study population (age=15.10±0.47 years, height=152.01±5.80 cm, weight=49.51±6.09 kg). The sample was divided into a control group (CG) and an experimental group (EG). Eleven players per group. The training program was made for the participants and the exercise training was supervised by the researchers. The PT exercises for the EG in which each exercise session involved 15±3 minutes of moderate-intensity exercise for the first four weeks and gradually increased to high-intensity exercises for the last six weeks. The PT was carried out for 10 weeks. Subjects were trained three times a week. A squat jump (SJ) and a counter-movement jump (CMJ) were used for data collection. Data were analyzed using mean and standard deviation, the paired t-test was used to compare pre-test and post-test data. The results marked improvements in VJ after the 10-week PT as significant gains were noticed in the post-test for EG on SJ t= 8.35, p< 0.05, CMJ t=5.70, p
