A identificação do arranjo de plantas que resulte menor competição intraespecífica permite melhor aproveitamento dos recursos disponíveis para o crescimento, composição e rendimento de grãos de soja. Assim, o presente estudo foi realizado com o objetivo de identificar o efeito de populações de plantas, em duas cultivares de soja, semeadas em dois anos agrícolas, nos teores de óleo e proteína. Foram instalados dois ensaios, sendo um no ano agrícola 2018/19, em semeadura realizada em 08/12/2018, e outro no ano 2019/20, em semeadura efetuada em 17/12/2019, na área experimental da Universidade Federal do Tocantins, Palmas (TO). O delineamento experimental utilizado, em cada ensaio, foi o de blocos casualizados (DBC), com 10 tratamentos e quatro repetições. Os tratamentos foram dispostos em esquema fatorial 2 x 5, representados por dois cultivares de soja (BÔNUS 8579 RSF IPRO e NS 8383 RR) e cinco populações de plantas (200, 250, 300, 350 e 400 mil ha-1). Foram avaliados os teores de óleo (%) e proteína (%) dos grãos. Populações entre 305 e 316 mil plantas ha-1, para a cultivar 8579 RSF IPRO, e próximas a 313 mil plantas ha-1, para NS 8383 RR, resultaram maior conteúdo de óleo e proteína nos grãos. Temperaturas altas e menor disponibilidade hídrica favoreceram o acumulo de óleo nos grãos. Menor disponibilidade de água na fase de enchimento de grãos proporcionou um maior teor de proteína. A cultivar NS 8383 RR apresentou o maior teor de proteína.

Brazil is the second largest producer of soybeans in the world. However, infestations of P. brachyurus have been decreased the gains for higher productivity and it may cause damages up to 50% for this production trait. We aimed with this study to evaluate the effectiveness of chemical and biological agents on for P. brachyurus control in two soybean cultivars, under three modes of application. A completely randomized block design was used in the factorial scheme 4 x 3 x 2 + 2, with 3 replications. The treatments consisted of a combination of four control agents, two chemical (abamectin, imidacloprid + thiodicarb) and two biologicals (Bacillus subtilis and Trichoderma atroviride); three ways of application (seed treatment, application in the seeding furrow and spraying at stage V1), two cultivars ('Anta 82’ and ‘Brasmax Desafio’) with different reproductive factors, and one control for each cultivar, with inoculation of P. brachyurus and without any control agent (negative control). Each plot received 1000 P. brachyurus individuals and were evaluated at 60 days after inoculation. All control agents can be indicated to manage P. brachyurus, T. atroviride and imidacloprid + thiodicarb are the most efficient ones. The ways of application do not influence the performance of the control agents for reducing nematodes.

RESUMO: O Brasil é o segundo maior produtor de soja no mundo. Contudo, infestações de P. brachyurus têm prejudicado a obtenção de maiores produtividades e podem causar danos de até 50% dessa variável produtiva. Objetivou-se com o presente estudo avaliar a eficácia de agentes químicos e biológicos no controle de P. brachyurus em duas cultivares de soja, sob três modos de aplicação. Foi utilizado o delineamento inteiramente casualizado no esquema fatorial 4 x 3 x 2 + 2, com 3 repetições. Os tratamentos foram constituídos pela combinação de 4 agentes de controle: 2 químicos (abamectina, imidacloprido + tiodicarbe) e dois biológicos (Bacillus subtilis e Trichoderma atroviride); 3 modos de aplicação (tratamento de sementes, aplicação no sulco de semeadura e pulverização no estádio V1), duas cultivares ('Anta 82’ e ‘Brasmax Desafio’) com diferentes fatores de reprodução, e 1 testemunha para cada cultivar, com inoculação de P. brachyurus e sem a aplicação de agente de controle. Todas as parcelas foram inoculadas com 1000 indivíduos de P. brachyurus e foram avaliadas aos 60 dias após a inoculação. Todos os agentes de controle são indicados no manejo de P. brachyurus, T. atroviride e Imidacloprido são mais eficientes. Os modos de aplicação não influenciam no desempenho dos agentes para redução dos nematoides.

This article examines the girls with deafness in schools who experience sexual harassment. The purpose of this study is to find a post-sexual harassment service model that is in accordance with the characteristics of girls with deafness and explain how schools pay attention to well-organized and theoretical programs using a preventive approach to mental health. Participants totaled 166 users consisting of 105 teachers, 38 students, 8 lecturers, 5 members of organizations for the deaf and other professions. The results showed that sexual harassment can occur physically and verbally towards the girls with deafness which can cause trauma. The girls with deafness are more at risk of being sexually abused than boys. They experienced very significant intimidation. The limited communication characteristics of girls with deafness cause trauma of sexual harassment, irrational beliefs that interfere with social functioning in the environment. There is a need for intervention in special mental health service programs such as REBT with Bisindo that are in accordance with the characteristics of students with deafness. The role of the teacher in preparing children to deal with face life in an increasingly complex society.
Improving the Articulation Ability of Children with Hearing Impairment Using Role Playing Method
Authors: Saptari Wina Try , Susetyo Budi , Tarsidi Iding
Published: March 2023

Children with hearing impairment have difficulty conveying what they want to express by speaking because of speech and language development barriers, so they can only express it through speech in a minimal voice. This study aims to determine the effect of using role playing to improve the articulation ability of children with hearing impairment, on the grounds that conversations with friends during role playing can improve their expressive language skills (articulation skills to communicate). Research using role playing for children with hearing impairment to improve their articulation skills is successful because intensive oral communication exercises can make children train their lip muscles so that later they will get used to speaking/articulate when communicating with people who can hear. Researchers recommend role playing can be used as an effort to improve the articulation ability of children with hearing impairment.

Published: March 2023

Aedes aegypti is an important vector of tropical diseases like Dengue, Zika, Chikungunya, and Yellow Fever and affects mainly countries located in tropical and subtropical zones, including Peru. Synthetic insecticides are used to control this vector, but they also cause a residual effect on the environment, whereas the vector has developed resistance to these compounds, so there is a current need to search for new control alternatives, such as the use of abundant natural resources. Therefore, this work aimed to evaluate the biocidal activity of extracts and oils from Cymbopogum citratus, Rosmarinus officinalis, and Minthostachys mollis on adult Aedes aegypti, as well as to evaluate their quality parameters. Furthermore, the chemical profile of the three species was assessed by ultra-high-performance liquid chromatography coupled with mass spectrometry (LC-MS/MS). The results showed that the aqueous/ethanolic extracts and the essential oils from the three evaluated species presented a biocidal effect on adult A.  aegypti. Regarding the analysis of the chemical profile, 15 compounds were identified in R. officinalis, while 29 compounds were identified from C. citratus and 30 compounds from M. mollis. Moreover, the extracts and oils presented quality parameters according to standards. In conclusion, the biocidal potential of the C. citratus, R. officinalis, and M. mollis on A. aegypti adults was reported so that they can be seen as a real natural alternative for the control of tropical diseases transmitted by this vector so that plant products are more eco-friendly and subject to lower resistance by target organisms.

Most, if not all, the vaccine candidates designed to counteract COVID-19 due to SARS-CoV-2 infection require parenteral administration. Mucosal immunity established by vaccination could significantly contribute to containing the SARS-CoV-2 pandemic, which is spread by infected respiratory secretions. The world has been impacted on many fronts by the COVID-19 pandemic since early 2020 and has yet to recover entirely from the impact of the crisis. In late 2022 and early 2023, China experienced a new surge of COVID-19 outbreaks, mainly in the country's northeastern region. With the threat of new variants like XBB 1.5 and BF.7, India might experience a similar COVID-19 surge as China and needs to be prepared to avoid destruction again. An intranasal vaccine can elicit multiple immunological responses, including IgG neutralization, mucosal IgA production, and T-cell responses. In order to prevent further infection and the spread of COVID-19, local immune responses in the nasal mucosa are required. iNCOVACC is a recombinant vaccine vectored by an adenovirus that contains a SARS-CoV-2 spike protein that has been pre-fusion stabilized. This vaccine candidate has shown promise in both early and late-stage clinical trials. iNCOVACC has been designed for intranasal administration via nasal drops. The nasal delivery system was created to reduce expenses for those living in poor and moderate-income countries. The newly introduced intranasal COVID vaccine will be beneficial in mass immunizing the public as it does not need any syringe and can be proven to be an effective method to boost immunity against the SARS-CoV-2 virus. This study uses natural language processing (NLP) techniques to analyze the Indian citizen's perceptions of the newly developed iNCOVACC vaccine in social media. For this study, we have used social media posts (tweets) as data. We have analyzed 125,300 tweets to study the general perception of Indian citizens regarding the iNCOVACC vaccine. Our results have indicated 43.19% of social media posts discussing the COVID-19 nasal vaccine in a neutral tone, nearly 34.29% of social media posts are positive, and 22.5% of social media posts discussions are negative. The general positive feeling that the iNCOVACC vaccine will work and the risks in the new vaccine are the two significant aspects Indian citizens voice out in social media posts about the iNCOVACC vaccine.

Members of Artiodactyla can contract the infectious disease Malignant Catarrhal Fever (MCF), which has a wide range of symptoms. Ten known viruses contribute to the disease, the two most significant ones being Ovine gamma herpes virus 2 (OvHV-2) and Alcelaphine gamma herpes virus 1 (AIHV-1). In the African subcontinent, AIHV-1 is seen in most MCF cases. In the Indian scenario, Ovine gamma herpes virus-2 is the main culprit. MCF is reported in certain pockets of India. Its threat to wildlife is not yet completely understood. In AIHV-1, wildebeests serve as the primary MCF reservoir, whereas with OvHV-2, the primary MCF reservoir is sheep. In India, OvHV-2 causes MCF in deer species, bison, and water buffaloe. The life cycle and properties of this virus are not yet wholly deciphered. To understand the impact of the disease and the threat it may pose in the future, we need to have diagnostic techniques in place. Currently, PCR is the most commonly used diagnostic technique. Work should be done on field-oriented tests like ELISA and LFA, which are helpful in areas without sophisticated lab facilities. Treatment protocols must be in place, as culling bovines is not an accepted policy in India. Probable plans for overcoming all these problems are discussed in this article.

Published: March 2023

This study was carried out to optimize the various approaches to analyze the effects of various variables on the total flavonoid content extraction from the roots of Helicteres hirsuta L. The existence of various compounds in the methanol fraction was accessed by using LC-MS/MS analysis. The results of the study identified the ideal parameters such as times (30 minutes); methanol solvent concentration (50%); ultrasonic frequency (12 Hz); and material/solvent ratio [1:30 (w/v)] for extracting the highest total flavonoids from the roots of H. Hirsuta. The study's results suggested that the total flavonoid value was 3.52684 (mg Catechin/g extract). The verified experiment obtained an actual value of 5.205 (mg Catechin/g extract). Further, the results of the study suggested the presence of 20 compounds of a flavonoid nature (66.667%) appearing in the purified methanol fractional extract. These compounds can inhibit DPPH free radicals at 50%, with an IC50 value of 536.760 g/mL, and they also have inhibitory activity on the growth of cancer cell lines with IC50 values ranging from 115.81 and 219.17g/mL. The human leukemia cell line (HL-60) exhibits the most significant cytotoxic response to a methanol extract from H. hirsuta root with an IC50 value of 115.81 g/mL.
Effects of Regenerative Agriculture Technologies on the Productivity of Cowpea in the Drylands of Embu County, Kenya
Authors: Mogaka Hezron
Published: March 2023

Cowpea (Vigna unguiculata) is an important indigenous multi-purpose crop grown in arid and semiarid areas of Sub-Saharan Africa (SSA). The cowpea has nutritional and economic value, especially for smallholder farmers in dry lands. However, poor farming practices have declined cowpea productivity over the years. Low soil nutrient replenishment exacerbates the situation, leading to low soil fertility. Uptake of regenerative agriculture (RA) technologies is critical to building more resilient ecosystems that improve soil fertility and agricultural productivity while mitigating climate change effects. This study was carried out to evaluate the impact of the uptake of RA technologies on the productivity of cowpea in the dry lands of Embu County, Kenya. A survey involving 400 farming households was conducted using a semi-structured questionnaire. Descriptive statistics and a stochastic log-linearized Cobb-Douglas production function were used for the data analysis. The study results showed that RA technologies commonly used by farming households were: cereal-legume intercrop, mulching, minimum tillage, crop rotations, pasture cropping, organic agriculture, and compost manure. The findings also revealed that inputs, farm size, labour cost, and used manure amount positively influenced cowpea productivity. The results also showed that cereal-legume intercrop, crop rotations, pasture cropping, and organic agriculture significantly influenced cowpea productivity, while minimum tillage showed a negative relationship. Therefore, the current study's results recommend that the uptake of RA technologies should be scaled to scale up cowpea productivity in dry lands. The study contributes to determining appropriate technologies for cowpea production in arid and semiarid areas. These results will help the government, policymakers, and other inventors to make the right decisions while disseminating or introducing innovations in dry areas.
Plant RNA-binding proteins as key players in abiotic stress physiology
Authors: Gururani Mayank Anand
Published: March 2023

Abiotic stress has a major effect on global crop production. Hence, plants have evolved and developed several response mechanisms to survive and grow under abiotic stresses. Plant cells can sense and respond to changes in different environmental stresses due to the specific modifications observed in gene expression, metabolism, and physiology. Only a few recognized sensors have been found due to the difficulty of functional redundancy in genes that code for sensor proteins. A defect in one gene causes no remarkable phenotypic changes in stress responses. Recent research has identified crucial RNA-binding proteins (RBPs) important for stimulus-specific responses. RBPs play a crucial part in plants’ growth and development, post-transcriptional gene regulation, and RNA metabolism induced during stress responses. Among the currently identified over 200 different RBPs, the majority of which are plant-specific and carry out plant-specific functions. As an essential component of plants’ adaptive process in different environmental conditions, RBPs regulate the following processes: RNA stability, RNA export, pre-mRNA splicing, polyadenylation, and chromatin modification. Plants have also developed different defense responses or molecular mechanisms to combat stress via genotypic and phenotypic expressions. With a unique understanding of RBPs in other organisms, RBPs functions in a plant are still limited. Hence, this review discusses the latest developments in RBPs function during the development and growth of plants, primarily under abiotic stress circumstances.

Chloranthus erectus is a herbaceous plant that has been used as a medicinal plant in several regions such as China and Southeast Asia. Although it possesses valuable medicinal properties, till now there is not much research has been carried out on the medicinal properties of this plant and the knowledge of this plant is limited among the research fertility. Therefore, this study aimed to identify the phytochemicals, total phenolic content (TPC), and antioxidant activity of leaf and twig of C. erectus in various solvents extract (hexane, petroleum ether, chloroform, ethyl acetate, and methanol). Phytochemical screening of extracts showed the presence of alkaloids, flavonoids, terpenoids, saponins, quinones, glycosides, and steroids. The highest phenolic content for leaf and twig samples was determined from the methanolic (9.64 ± 0.15 µg GAE/g) and hexanoic extract (7.39 ± 0.27 µg GAE/g), respectively. Meanwhile, the highest antioxidant activity was reported from the methanolic extract of both leaf (88.36 ± 0.24%) and twig (91.25 ± 0.10%) samples. Hence, the results of the study can be concluded that C. erectus has the potential to become a good natural antioxidant and the information from this study can be utilized by the communities as well as other researchers.

Published: March 2023

Radical cystectomy is the gold standard treatment for aggressive bladder cancer. Pelvic lymphadenectomy is an important step. This procedure is crucial for the cancer staging, determination of further treatment strategy, and optimization of surgical outcomes. Currently, the sentinel lymph node concept is being actively developed, which allows to reduce the required extent of pelvic lymph node dissection. Decrease in number of removed pelvic lymph node improves surgical safety of the patient. Indocyanine green near-infrared fluorescence is the main approach to the intraoperative visualization of sentinel lymph nodes. The prospects of this diagnostic technique application in radical cystectomy performed for bladder cancer determine the vector of future scientific research in this area.

La teoría de los tópicos aplicada a la música para cine, ¿una adaptación posible?
Authors: Centeno Osorio José Luis
Published: March 2023

La teoría de los tópicos musicales fue introducida por Leonard Ratner en 1980. Enmarcada en la semiótica musical, trata de demostrar la relación entre elementos de la música del siglo XVIII y el significado que adquieren gracias a las convenciones de uso de la época. La música que se ha escrito para cine tiene una clara influencia del pasado, por tanto, algunos de estos tópicos se pueden encontrar en ella. Los catálogos de cine mudo así lo demuestran, como la Enciclopedia de música para películas de Ernö Rapée (1925). Este artículo trata de indagar en la posibilidad de aplicar estas teorías en la música para cine, partiendo de la semiótica musical. Para ello, se plantea si es posible identificar esos tópicos en diversos géneros, y cómo, gracias a las convenciones del lenguaje audiovisual, el espectador les dota de significado.
El TJUE abre las puertas a la resolución contractual en los vehículos afectados por el Dieselgate
Authors: Vecina Aznar Álvaro
Published: March 2023

El 14 de julio de 2022 el TJUE dictó tres sentencias de gran relevancia para el conocido como “Dieselgate”. En ellas dejó sentado que los vehículos del grupo Volkswagen afectados en su día y que fueron objeto de reparación, tienen una nueva –o persistente– falta de conformidad. Esto es así puesto que el sistema que llevan integrado para controlar las emisiones de gases contaminantes, fruto de la reprogramación que sufrieron, vulnera la legislación europea y, en tal medida, provoca que los vehículos no sean conformes. De esta forma, el intento frustrado de puesta en conformidad habilita al consumidor a pedir la resolución del contrato y a obtener la totalidad del precio pagado, o a la reducción del precio.
El TS sienta jurisprudencia (art. 1.6 CC): entre 1999 y 2009 las TAEs del 23% al 26% eran normales y, por tanto, no usurarias
Authors: Agüero Ortíz Alicia
Published: March 2023

La STS 643/2022 de 4.5.2022 (Estrella I) rechazó que una tarjeta con una TAE del 24,5% fuera de usuraria ya que los tipos aplicados a operaciones similares al tiempo de la contratación oscilaban entre el 23 y 26%. El TS emitió una nota de prensa y un auto aclaratorio explicando que ello no comportaba un cambio de doctrina porque se limitó a aceptar los hechos fijados en la instancia. Sin embargo, la STS DE 4.10.2022 (Estrella II), reitera el criterio sin que ello se mencionara en las instancias previas. Además, la STS 662/2022 de 13.10.2022 no altera en nada este cambio de criterio ya que en ella no se cuestiona el carácter usurario de la tarjeta de crédito, lo que devino firme en apelación al no ser recurrido por ninguna de las partes.
Régimen europeo en ciernes en materia de responsabilidad derivada de los Sistemas de Inteligencia Artificial
Authors: Navas Navarro Susana
Published: March 2023

La publicación el 28 de septiembre de 2022 de dos Propuestas de Directiva que abordan aspectos relacionados con los daños ocasionados por sistemas de inteligencia artificial dan pie a interesantes y controvertidas cuestiones. En este trabajo tras exponer aspectos comunes a ambas y establecer también las diferencias, me adentro, en primer lugar, en el estudio de la Propuesta de Directiva de responsabilidad civil extracontractual derivada de la puesta en circulación o en servicio en el mercado de sistemas de inteligencia artificial para concluir, entre otras consideraciones, que se alivia muy poco -si es que lo hace- la carga de la prueba a la víctima. Seguidamente trato algunos aspectos en relación con la Propuesta de Directiva de responsabilidad civil por defectos en los productos en relación con los mismos sistemas que, en este caso, quedarían embebidos en la expresión “programa informático”. Se concluye, entre otros aspectos de interés, que la gran cantidad de conceptos jurídicos indeterminados y las posibilidades de presunciones iuris tantum que deja abiertas la Propuesta (defecto, nexo causal o ambos) no hace fácil la labor del juzgador ni su incorporación a los derechos internos.
Más allá del Dieselgate: el insostenible caso en favor de remedios sostenibles en las ventas al consumidor
Authors: Carrasco Perera Ángel Francisco
Published: March 2023

A diferencia del TJUE y del BGH, la jurisprudencia española (con dos sentencias de la sala de lo civil del Tribunal Supremo) ha sido mayoritariamente contraria hasta la fecha al planteamiento que condena el escándalo del Dieselgate como incumplimiento de expectativas contractuales protegidas. Según la mayoría de los tribunales españoles, el comprador no puede demandar por falta de conformidad (especialmente cuando el fabricante ha ofrecido una reparación gratuita del dispositivo de software), no puede rescindir por incumplimiento sustancial y no puede obtener indemnización por daños y perjuicios inexistentes; deja abierto, sin embargo, un premio de consolación de 500 euros como “daños inmateriales”, con el bizarro argumento de que VW es responsable de pagar “algo” por su claro incumplimiento del derecho (público) regulatorio. La presente contribución pretende explicar que los “remedios previstos” en la Directiva 2019/771 son en efecto “insostenibles”, que su “insostenibilidad” no puede matizarse a través del “equilibrio de principios”, que, por el momento, la Directiva (UE) 2019/771 no puede interpretarse en el sentido de que ofrece remedios en el derecho contractual para las prácticas ambientales insostenibles de los vendedores y, principalmente, que, rebus sic stantibus, el derecho privado en los contratos es un instrumento inadecuado para otorgar derechos subjetivos a las partes contractuales para remediar las calamidades ambientales que el comprador no ha incorporado en el precio del contrato como “expectativas legítimas entre las partes”.
Differences in Folate and Vitamin B12 Serum Levels Between Mothers Whose Children were Diagnosed with Non-syndromic Cleft Lip and Cleft Lip with Palate

Published: March 2023

Non-syndromic (NS) cleft lip (CL) and cleft lip with palate (CLP) are abnormalities in the orofacial area that are not accompanied by abnormalities in the head and neck and have normal physical growth and cognitive development. Cleft lip and CLP are caused by two factors, genetic and environmental factors which include deficiencies of micronutrients such as folate and vitamin B12. This study aimed to determine the differences in folate and vitamin B12 serum levels between mothers whose children were diagnosed with NS CL and CLP. An analytical observational study was conducted on folate and vitamin B12 serum levels from 44 mothers whose children were diagnosed with NS CL and CLP. Data were analyzed by t-test for folate serum levels and Mann Whitney for vitamin B12 serum levels. All mothers whose children were diagnosed with non-syndromic CL and CLP, respectively, had normal serum folate levels. Meanwhile, most of the mothers suffered from vitamin B12 deficiency, both mothers whose children were diagnosed with CL (91.6%) and mothers whose children were diagnosed with CLP (93.75%). The mean folate serum level between CL was slightly higher than CLP (p-value = 0.711) but showed no statistical difference in folate levels in the two groups. The median B12 levels between CLP were slightly higher (p-value = 0.394), which indicated that the B12 levels between the two groups were not statistically significant. There were no differences in folate and vitamin B12 serum levels between mothers whose children were diagnosed with non-syndromic cleft lip and cleft lip with palate.

The decline in estrogen at menopause leads to a loss of neuroprotective function. One of the effects is Alzheimer’s disease (AD), with clinical manifestations of dementia, decreased memory function, language, thinking, and learning. The pathology of AD is widely studied but not completely understood. Various animal models have been used but have not been able to represent the pathology of AD fully. This study aimed to determine the effect of oral and intraperitoneal induction of aluminium chloride (AlCl3) on the memory function of menopausal model white rats (Rattus norvegicus strain wistar). This study used 16 female rats, divided into four groups, namely the negative control group (K1), the ovariectomy group (OVX, K2), and the OVX + AlCl.6H20 group 100 mg/kg BW orally (K3), and the OVX + AlCl3.6H20 group. 70 mg/kg body weight intraperitoneally. AlCl3.6H20 induction was given for six weeks. In the last five days, the Morris water maze test was carried out. From the MANOVA test, the p-value of F values in Pillai’s trace, Wilks‘ Lambda, Hotelling’a Trace, and Roy’s Largest Root were < 0.05. Based on the post hoc Bonferroni test on the fifth day of the trial, there was a significant difference between the standard and OVX groups with the AlCl3 induction group, and there was no significant difference between the oral and intraperitoneal induction groups. Conclusion: There is no significant effect of oral and intraperitoneal induction of Aluminum Chloride (AlCl3) on the memory function of white rats (Rattus norvegicus strain wistar) menopausal model.

Authors: Marlian Y Nungki , Setiawan Agus , Manggala P Rama
Published: March 2023

With increasing age, there is a decrease in the degenerative body, such as a decrease in musculoskeletal, neuromuscular, and cardiovascular functions, as well as a reduced ability to perform daily activities. One of the declines in musculoskeletal function is a decrease in muscle function, which causes muscle fibres to shrink, causing a decrease in strength, muscle mass, and bone mass. This causes dynamic balance disorders in the elderly. To improve and maintain dynamic balance, a combination of Tera Gymnastics and Square Stepping exercises are given to the elderly. This study aimed to determine whether there is an effect of the combination of Tera Gymnastics and Square Stepping Exercises on the level of the dynamic balance of the elderly in Sasana Malang. The research design was pre-experimental, namely the One Group Pre-Test and Post-Test Design. The study was focused on 35 elderly people for four weeks. The research instrument used was the Timed Up and Go Test. Shapiro Wilk Test data was normal, Pre-Test was 14.2317, and Post-Test was 11.9480. Paired Sample T Test significance was 0.000, H0 was rejected and H1 was accepted. It was discovered that a combination of Tera Gymnastics and Square Stepping exercises for 4 weeks increases the dynamic balance of the elderly in Sasana Malang.

Authors: Utami Resti , Kholifah Siti
Published: March 2023

Low birth weight (LBW) infants are at risk for vertical and horizontal transmission of COVID-19. A mother’s ability to prevent infection in LBW infants is decided by their knowledge, self-efficacy, and abilities of the mother in carrying out infection-prevention care. This study aimed to analyze the relationship between mothers’ knowledge and self-efficacy with their ability to prevent infection in LBW infants during the COVID-19 pandemic. This study used a correlational design. This study included 84 respondents who were selected through purposive sampling in the perinatology room. The statistical test used was the Spearman Rho. The outcomes confirmed a relationship between a mother’s knowledge (r = 0.249; p = 0.022) and self-efficacy (r = 0.313; p = 0.004) with the mother’s ability to prevent infection in LBW infants. The level of strength of the positive relationship between a mother’s knowledge and the mother’s ability to prevent infection in LBW infants is 0.249, or very vulnerable. The level of the strength of the positive relationship between maternal self-efficacy and the mother’s ability to prevent infection in LBW infants is 0.313, or sufficient. Therefore, increased knowledge and self-efficacy of mothers may have an impact on increasing the ability of mothers to prevent infection in LBW.

Published: March 2023

Obesity in developing countries is an epidemic at almost all age levels. The prevalence of obesity continues to increase with age and can reach its peak in adulthood. Increased Body Mass Index (BMI) has a close relationship with poor sleep quality. Increasing body weight (BB) in adolescence will cause an increase in the number of fat cells. The research design used in this study was experimental research,. In conducting our research, we focused on the influence of the variables. The population that we used in this study was the UMM nursing students in the class of 2017-2019, with a total of 495 students. The technique we used in this study was multi-stage (cluster) sampling to reach a proportional sample size through a probability proportional to size (PPS). The number of respondents we got was 71 students. Data collection was done online through private messages sent to the class leader or commander level of each class and distributed a questionnaire. The results shown were that the two variables had no relationship. Based on the Spearman’a rho correlation test, the significance value or sig.2-tailed = 0.897, where the value is greater than α (0.05). The results of this study indicated that the strength of the relationship was (-0.016), which means that the relationship between sleep quality and BMI has a very weak relationship or correlation and the relationship between the two variables is unidirectional. In conclusion, there is no relationship between sleep quality and body mass index in UMM Nursing undergraduate students.

During the COVID-19 pandemic, there were many large-scale restrictions on routine services, including maternal and neonatal health services. This study used a correlational design to analyze the relationship between pregnancy during COVID-19 and the neonate’s condition. Samples are pregnant women between 2020 and 2021, totaling 108 samples obtained by random sampling. Data collection used questionnaires, structured interviews, and documentary studies. The approach used was a retrospective about Ante Natal Care visits during COVID-19 with the birth weight of the baby. Data analysis was performed using the Chi-square. There is a relationship between pregnant women’s and babies’ weight during COVID-19 with a p-value of 0.016 and an OR of 3.967 (95% CI 1.22-12.879). In addition, the number of respondent visits is also related to babies’ birth weight (P-value of 0.004 with OR 168 (95% CI 0.045-0.625). Meanwhile, the size of the mother’s upper arm circumference and blood pressure is unrelated to the baby’s birth weight. During the COVID-19 period, restrictions on Ante Natal Care visits caused pregnancies to become out of control. Lack of education about nutrition and stress levels of pregnant women contributes to pregnancy outcomes.

Published: March 2023

The increase in the productivity of the elderly population causes the elderly to become a population at risk. The health problems of the elderly are caused mainly by non-communicable diseases (NCDs). Soft tissue pain, functional limitations, and pelvic floor muscle disorders (PFMDs) predominate in the disease. The incident of the relationship between sexual activity and PFMDs during the pandemic is an interesting discussion. The research discussion uses bibliometric methods and a simple PICO review to analyze linkages and metadata. Pathophysiological sequences show a link between the two. Meanwhile, bibliometric studies indicate that studying the pelvic floor and organs is a novel recommendation compared to sexual dysfunction.

Dyslipidemia is a lipid fraction abnormality in the form of an increase in total cholesterol, LDL, and triglyceride levels and a decrease in HDL. Red Cabbage Aqueous Extract (RCE) contains antioxidants, one of which is anthocyanins, that can increase HDL levels. This research was conducted to determine the effect of RCE on HDL levels of white male rats induced by an atherogenic diet. True experimental with post-test only control group design with 15 rats divided into the standard group (KN: regular feed), negative control group (K-: atherogenic diet), and three treatment groups (P1: atherogenic-diet with RCE doses of 6.65 mg; P2: atherogenic-diet with RCE doses of 13,3 mg; and P3: atherogenic-diet with RCE doses of 26.6 mg/100grBW) was used. The HDL measurement method used spectrophotometry. Brassica oleracea L extract had no significant effect (Kruskal-Wallis test p = 0.465) on HDL levels of white male rats. This result also happened due to the low bioavailability of anthocyanins in aqueous extract. The linear regression test results showed that the relationship’s strength was 0.031 or very weak with a linear proportional correlation, increasing the dose and increasing HD levels. Based on the results of the tests, there was no significant effect of giving Red Cabbage (Brassica oleracea) Aqueous Extract on HDL levels of white male rats (Rattus norvegicus wistar strain), which was induced by an atherogenic diet.
