Urbanization affects all elements of the pre-urban environment, including soils, hydrology, vegetation, and microclimate. Recently, Saudi Arabia has experienced rapid urbanization and growth. Thus, the country's biodiversity has been threatened. In Riyadh, beetle assemblages were assessed along a rural-suburban-urban gradient. A total of 2,791 individuals from 94 species belonging to seven families were collected at 15 sites along three different gradients of urbanization in Wadi Hanifa. Tenebrionidae dominated abundance (60.1%) and richness (38%). Beetle abundance, evenness, and diversity were not different among habitats; however, species richness was higher in rural habitats. DCA and CCA analyses showed distinct differences among sites along gradients. Urbanization intensity, soil variables, and land cover were significantly correlated with DCA axis 1, while elevation and flora were significantly correlated with DCA axis 2. The most critical operating environmental variables in Wadi Hanifa were buildings, elevation, soil organic carbon, litter cover, and litter depth, as well as plants such as Launaea capitata, Lycium shawii, Alhagi graecorum, and Heliotropium currasavicum. Ten species in our study are associated with urban habitats, six with suburban habitats, and seven with rural habitats. Consequently, expanding urban areas may negatively affect the richness and composition of beetles and may result in the loss of some native species.
Assessment of Morpho-physiological Features of Rice Samples in Flooding Conditions
Authors: Golubova Valentina , Kostylev Pavel
Published: January 2023

The article presents the results of a morpho-physiological assessment of rice samples by the strength of growth, as well as an assessment of the degree of development of the conducting system of the flag leaves of rice plants. The resistance of varieties to flooding is very relevant in the fight against weeds due to the deep layer of water that weeds cannot overcome. Currently, there are no zoned varieties in Russia that would meet these requirements. Therefore, the problem of creating such rice varieties is urgent, as it will reduce production costs, reduce grain losses during harvesting, improve the quality of the products obtained, and also reduce the pesticide load on the ecosystem. As a result of research, a number of studied samples revealed the potential to quickly lengthen the first leaves, overcome a large layer of water and accumulate vegetative mass. As a result of the evaluation of the conducting system of the flag leaf of rice plants, it was found that in plants with the flood resistance gene Sub1A, which stops growth under water, the conductive beams were smaller in comparison with other fast-growing samples with the AG, Sk genes. Consequently, fast-growing samples have bigger sizes of the conducting system as a resistance mechanism.

Dyslipidemia is a disorder where abnormally lipid concentrations circulate in the bloodstream. The disorder is common in type 2 diabetics (T2D) and is linked with T2D comorbidities, particularly cardiovascular disease. Dyslipidemia in T2D is typically characterized by elevated plasma triglyceride and low high-density lipoprotein cholesterol (HDL-C) levels. There is a significant gap in the literature regarding dyslipidemia in rural parts of Africa, where lipid profiles may not be routinely captured through standard surveillance activities. This study aimed to characterize the prevalence and demographic profile of dyslipidemia in T2D patients in the rural community of Ganadougou, Mali. We performed a cross-sectional study of 104 subjects with T2D in Ganadougou between November 2021 and March 2022. Demographic and lipid profiles were collected through cross-sectional surveys and blood tests. The overall prevalence of dyslipidemia in T2D patients was 87.5% (91/104), which did not differ by sex (p = .368). High low-density lipoprotein cholesterol (LDL-C) was the most common lipid abnormality (78.9%, [82/104]). Dyslipidemia was associated with age and hypertension status (p = .013 and p = .036, respectively). High total and high LDL-C parameters were significantly associated with hypertension (p = .029 and p = .006, respectively). In low-resource settings such as rural Mali, there is a critical need to improve infrastructure for routine dyslipidemia screening to guide its prevention and intervention approaches. The high rates of dyslipidemia observed in Gandadougou, consistent with concomitant increases in cardiovascular diseases in Africa suggest that lipid profile assessments should be incorporated into routine medical care for T2D patients in African rural settings.

Introduction
Headache is a common public health problem, but its burden could be avoided by raising headache awareness and the appropriate use of acute medication and prophylactic medication. Few reports on raising headache awareness in the general public have been reported, and there are no reports on headache awareness campaigns through social networking services (SNS), or social media, in Japan. We prospectively performed a headache awareness campaign from March 2022 through 2 SNS, targeting nurse and wind instrumental musicians, because they are with high headache prevalence.
Methods
Through the 2 SNS, the article and video were distributed, respectively. The article and video described the 6 important topics for the general public about headaches, which were described in the Clinical Practice Guideline for Headache Disorders 2021. Just after reading or watching them as e-learning, we performed online questionnaire sheets to investigate the awareness of the 6 topics through the 2 SNS. The awareness of the 6 topics before and after the campaign was evaluated.
Results
In the SNS nurse-senka, we obtained 1191 responses. Women comprised 94.4%, and the median (range) age was 45 (20 to 71) years old. Headache sufferers were 63.8%, but only 35.1% had consulted doctors. In the SNS Creatone, we got the response from 134 professional musicians, with 77.3% of women. The largest number of respondents were in their 20s (range 18-60 years old). Headache sufferers were 87.9%. Of them, 36.4% had consulted doctors, 24.2% were medication-overuse headache. The ratios of individuals who were aware of the 6 topics significantly increased from 15.2%-47.0% to 80.4-98.7% after the online questionnaire in both SNS (p < 0.001, all).
Conclusions
We conducted this headache awareness campaign through e-learning and an online survey via 2 SNS. The ratios of individuals who were aware of the 6 topics about headaches significantly increased 1 month after e-learning. Our results suggest that e-learning and online survey can improve headache awareness. The materials in this campaign can be installed into smartphone applications and further spread on SNS, leading to strong influence. With rapid digital transformations such as online telemedicine and artificial intelligence diagnosis, raising awareness will be more efficient and effective and should be important.

Published: January 2023

The study aims to explore the relationship between Intellectual Human Capital (IHC) and Corporate Social Innovation (CSI) in Oman. This research used a quantitative method. The population of this study was 74 companies on Muscat Stock Exchange (MSX) for the year ended 2021 in Oman. The sample size of this project was 63 from two sectors of listed companies (Financial Sector 31 and Industrial Sector 32). The study findings found there is a positive impact on the relationship between Intellectual Human Capital (IHC) and Corporate Social Innovation (CSI) in Oman. IHC contributes to increasing Social Innovation (SI) in companies, greatly influencing social innovation. Firms that use IHC have high social innovation because the IHC depends on the knowledge of human resources that impacts social innovation as it expands to other areas of the company.

Published: January 2023

Marco teórico: La familia constituye la red de apoyo más potente y eficaz en la vida. En la atención del adulto mayor, la familia ocupa un lugar fundamental en la formación de comportamientos implicados en la salud, así como en las decisiones sobre el uso de servicios profesionales. El objetivo del estudio fue evaluar la asociación entre la salud percibida del adulto mayor y su funcionalidad familiar. Método: Se realizó un estudio cuantitativo y transversal en una muestra de 120 adultos mayores de tres localidades del Valle del Mezquital de Hidalgo, México. Los instrumentos de recolección de datos fueron la escala de Concepción de Salud y APGAR de la Familia. La asociación entre la salud percibida y la funcionalidad familiar se evaluó mediante modelos de regresión logística. Para evaluar la asociación entre la salud percibida y la funcionalidad familiar se realizaron modelos de regresión logística múltiple. Resultados: Se encontró que los adultos mayores con algún grado de disfuncionalidad familiar presentaron una mayor posibilidad de percibirse como no saludables (RM=13.48; IC 95%=2.65, 68.62) en comparación con quienes presentaron una funcionalidad familiar normal.  Conclusión: La disfunción familiar en la que viven los adultos mayores es un factor que se asocia con la percepción que tienen los mismos de su salud.

La COVID-19 ha afectado de forma significativa a las personas mayores que se encuentran institucionalizadas en centros residenciales. El objetivo del estudio fue analizar si la situación de confinamiento influyó en la percepción de la calidad de vida de los residentes de un centro para personas mayores. Método. En el estudio participaron 12 personas mayores con edades comprendidas entre los 68 y los 93 años de un centro institucionalizado.  Se utilizó el Cuestionario de Evaluación de Calidad de Vida en Contexto Residencial, una encuesta sociodemográfica, el Mini-Examen Cognoscitivo y escala de deterioro global. Se utilizaron pruebas análisis de frecuencias y porcentajes, así como análisis de medias t de student. Resultados. Se ha obtuvo que las medias de salud eran más altas antes del confinamiento, así como las visitas y el establecimiento de relaciones sociales y familiares. Por el contrario, la satisfacción con la vida fue mayor después de la situación de confinamiento al igual que el nivel de capacidad funcional de los residentes lo que supuso la necesidad de más ayuda por el empeoramiento funcional percibido. Respecto a las actividades y el ocio, así como a la calidad ambiental, no encontraron diferencias de medias significativas. Conclusiones. La situación de la COVID-19 ha puesto de relieve la afectación de la calidad de vida de las personas mayores institucionalizadas en centros residenciales, objetivándose un detrimento de la misma en la situación de confinamiento. Ello muestra la necesidad de realizar intervenciones que mejoren la percepción de calidad de vida, sobre todo en situaciones de emergencia.

Published: January 2023

We establish a fluid property model for carbon capture and storage (CCS) within the unified framework of classical compositional reservoir simulation by employing the standard volume-translated Peng-Robinson (PR-VT) Equation of State (EOS) and Lohrenz-Bray-Clark (LBC) viscosity correlation. We spend tremendous effort on the collection of high-quality data and our model demonstrates excellent numerical accuracy because each parameter is well defined through the extensive calibration with data from experiments, National Institute of Standards and Technology (NIST) and reliable correlations. We successfully address all the questions that could be encountered in the prediction of phase behavior and physical and transport properties of CCS fluid systems: the multiple components of injection gas, the gas solubility in aqueous phase and water (no salts) solubility in non-aqueous phase, the density and viscosity of aqueous phase with dissolved gas and of non-aqueous phase with dissolved water, and the impact of different ionic species on gas solubility, density and viscosity of aqueous phase. Moreover, we propose a modified procedure to perform the multi-component multi-phase equilibrium computation that implements our model and overcomes the challenge due to thermodynamic inconsistency caused by phase-dependent parameters. Since CO2/brine system has zero degree of freedom at fixed temperature and pressure in two-phase state, we are able to create the ‘exact’ black oil table by applying the phase equilibrium computation integrated with our model. It is of particular significance because the corresponding black oil simulation for CO2 injection in saline aquifer could be performed on any commercial reservoir simulator in large scale to satisfy most of the requirements of CCS studies.
Multi-stakeholder perspectives regarding preferred modalities for mental health intervention delivered in the orthopedic clinic: A qualitative analysis

Published: January 2023

Background: Although depressive and anxious symptoms negatively impact musculoskeletal health and orthopedic outcomes, a gap remains in identifying modalities through which mental health intervention can realistically be delivered during orthopedic care. The purpose of this study was to understand orthopedic stakeholders’ perspectives regarding the feasibility, acceptability, and usability of digital, printed, and in-person intervention modalities to address mental health as part of orthopedic care. Methods: This single-center, qualitative study was conducted within the orthopedic department of a tertiary care center. Semi-structured interviews were conducted between January and May 2022. Two stakeholder groups were interviewed using a purposive sampling approach until thematic saturation was reached. The first group included adult orthopedic patients who presented for management of ≥ 3 months of neck or back pain. The second group included early, mid, and late career orthopedic clinicians and support staff members. Stakeholders’ interview responses were analyzed using deductive and inductive coding approaches followed by thematic analysis. Patients also performed usability testing of one digital and one printed mental health intervention. Results: Patients included 30 adults out of 85 approached (mean (SD) age 59 (14) years, 21 (70%) women, 12 (40%) non-White). Clinical team stakeholders included 22 orthopedic clinicians and support staff members out of 25 approached (11 (50%) women, 6 (27%) non-White). Clinical team members perceived a digital mental health intervention to be feasible and scalable to implement, and many patients appreciated that the digital modality offered privacy, immediate access to resources, and the ability to engage during non-business hours. However, stakeholders also expressed that a printed mental health resource is still necessary to meet the needs of patients who prefer and/or can only engage with tangible, rather than digital, mental health resources. Many clinical team members expressed skepticism regarding the current feasibility of scalably incorporating in-person mental health support into orthopedic care. Conclusions: Although digital intervention offers implementation-related advantages over printed and in-person mental health interventions, a subset of often underserved patients will not currently be reached using exclusively digital intervention. Future research should work to identify combinations of effective mental health interventions that provide equitable access for orthopedic patients. Trial registration: Not applicable.
Examining the Connectivity of Antarctic Krill on the West Antarctic Peninsula: Implications for Pygoscelis Penguin Biogeography and Population Dynamics
Authors: Gallagher Katherine L. , Dinniman Michael S. , Lynch Heather J.
Published: January 2023

Antarctic krill (Euphausia superba) are considered a keystone species for higher trophic level predators along the West Antarctic Peninsula (WAP) during the austral summer. The connectivity of these populations may play a critical role in predator biogeography, especially for central-place foragers such as thePygoscelispenguins that breed along the WAP during the austral summer. Here, we used a physical ocean model to examine adult krill connectivity in this region using simulated krill with realistic diel vertical migration behaviors across four austral summers. Specifically, we examined krill connectivity around the Adélie gap, a 400 km long region along the WAP with a distinct absence of Adélie penguin colonies, to determine if krill population connectivity around this feature played a role in its persistence. Our results indicate that krill populations north and south of the Adélie gap are nearly isolated from each other and that persistent current features play a role in this inter-region connectivity, or lack thereof. Our results indicate that simulated krill released within the Adélie gap are quickly advected from the region, suggesting that the lack of local krill recruit retention may play a role in the persistence of this biogeographic feature.

Authors: Dabelah Kamal Ibrahim , Luwaimi Sajidah Al , Al-Saleem Salma Ali , Akbar Zahida
Published: January 2023

Background
The international guidelines have recommended that neonates and infants shall be placed on exclusive breastfeeding for at least six months. Previous studies on breastfeeding rates in Saudi Arabia have reported less than the optimal breastfeeding rate. The current study aimed to assess the breastfeeding rate in the eastern region of Saudi Arabian.
Methods
The cross-sectional study was conducted over the period of 6 months in a tertiary care hospital designated as a Baby-friendly initiative hospital (BFHI). The study utilized a modified Iowa Infant Feeding Attitude Scale (IIFAS) tool, which consists of a 21-item validated questionnaire. All the enrolled mothers were interviewed face-to-face using a modified IIFAS tool in the postpartum room. After the completion of the interview, the mothers were educated about the importance of breastfeeding. The enrolled mothers were again interviewed after six months period using the same modified IIFAS tool.
Results
During the study period, a total of 156 women were enrolled in the study. The average age of the participants was 33.5 ± 4.6 years. The majority of participants i.e., 112 (71.9%) gave birth by vaginal delivery method. Most of the children (57.7%) started breastfeeding only at the time of birth. But the number declined significantly low to 21.7% participants after six months. In contrast, the number of children who started formula feeding increased significantly from 2.6–31.9%. As per the defined criteria of knowledge scoring, only 27 (17.3%) were observed to have good knowledge. Around two-third of participants reported having adequate knowledge, while 28 (17.9%) participants had poor knowledge.
Conclusion
Compared to previous studies conducted among Saudi mothers, the exclusive breastfeeding rate after delivery was observed to be low. Moreover, the breastfeeding attitude and continuation after six months of birth was also found to be low as compared to previous studies. The current study highlights the importance of continuous education and efforts to promote the breast feeding among Saudi mothers.

O entendimento da variabilidade dos atributos químicos do solo é fundamental para verificar a alteração de rendimento e aprimorar o manejo em áreas de cultivos agrícolas. O objetivo deste trabalho foi avaliar a produtividade da soja através da elaboração de mapa de produtividade e a correlação entre a variabilidade dos atributos químicos do solo e o Índice de Vegetação da Diferença Normalizada (NDVI) na cultura da soja. A área experimental localiza-se no município de Douradina-MS. Através do aplicativo para iOS – Sirrus realizou a demarcação da área de 45,32 ha, com uma grade amostral de 1 ponto a cada 3 hectares, num total de 16 pontos amostrais. Foi realizada a coleta do solo na camada de 0-20 cm de profundidade, onde foram analisados os teores de Cálcio, Fósforo, Potássio, Magnésio, Capacidade de Troca de Cátions, Acidez Potencial, Potencial Hidrogeniônico, Saturação por Bases e Matéria Orgânica. Quando a cultura atingiu o ponto de colheita, foram colhidas 2 linhas de 1,5 m de amostras de soja, para determinar a umidade dos grãos colhidos e a produtividade da cultura e, posteriormente a umidade dos grãos foi corrigida a 13%. Os dados foram submetidos a estatística descritiva, geoestatística, e correlação de Pearson. Todos os atributos químicos e produtividade da soja apresentaram forte dependência espacial, entretanto o Fósforo e a Capacidade de Troca de Cátions mostraram dependência espacial moderada. O pH e a produtividade obtiveram correlação negativa e apenas o Magnésio teve correlação positiva e significativa com o NDVI.

A presente pesquisa tem o objetivo de analisar a situação ambiental de propriedades pesquisadas na zona rural da Região Crajubar, no Cariri cearense, por meio de um estudo de caso nos municípios Crato, Juazeiro do Norte e Barbalha. Para a análise da situação ambiental, procedeu-se com a realização de entrevistas estruturadas aos produtores rurais dos referidos municípios. Os parâmetros de análise utilizados foram: Fonte de água; Área de Preservação Permanente (APP); Reserva Legal; Agrotóxicos e Fertilizantes; e manejo de Resíduos sólidos. Dos resultados, destaca-se que as condições da região Crajubar, para os parâmetros analisados, demonstraram um nível regular de sustentabilidade ambiental, considerando a amostra desta pesquisa, tendo obtido coeficiente 0,6 para o índice de sustentabilidade ambiental. Evidenciou-se baixa adequação ambiental das propriedades, quando relacionadas à utilização de agrotóxicos, fonte de abastecimento de água e à destinação inadequada dos resíduos sólidos, prática destacada na maioria dos casos. Sendo, portanto, necessário promover ações e políticas públicas capazes de oportunizar melhores condições de vida e saúde trabalho ao produtor rural, inclusive oportunizando um meio ambiente adequado, equilibrado e saudável, corroborando para a sustentabilidade no ambiente agrário e permanência no campo.

Reconhecidas pelo desempenho do sistema radicular, as forrageiras Urochloa spp. são espécies que melhoram os atributos físicos do solo (porosidade total, microporisidade, macroporosidade, densidade, diâmetro médio ponderado, diâmetro médio geométrico, percentagem de agregados, peso seco de raiz e resistência do solo a penetração). Nesta perspectiva, o objetivo deste trabalho foi caracterizar as propriedades físicos de um Latossolo Vermelho sob diferentes forrageiras do gênero Urochloa em Rio Verde - GO. O ensaio foi conduzido a campo, no período de entressafra, com plantio em faixas das espécies Urochloa brizantha Paiaguás, Urochloa Ruzizziensis e Urochloa brizantha Marandú. Ao final do ciclo das Urochloas, foram coletadas amostras de solo para avaliações de densidade, porosidade, textura, diâmetro médio ponderado e geométrico, índice de estabilidade de agregados, resistência à penetração e umidade do solo, além de peso seco da raiz. O modelo experimental utilizado foi parcelas divididas e análise de componentes principais. As espécies Urochloas brizantas (Paiaguás e Marandú) apresentaram maior potencial de formação de agregados do solo, devido a capacidade do rompimento de raízes dessas espécies. O peso seco de raízes foi o parâmetro que mais explicou a variância causada pelas diferentes Urochloas.

Objetivou-se avaliar a associação entre tempo de exposição a agrotóxico com variáveis bioquímicas, antropométricas e de composição corporal de mulheres rurais. Trata-se de um estudo transversal realizado com 37 mulheres moradoras em comunidades rurais da zona da mata mineira, maiores de 18 anos e que não aplicavam agrotóxicos, mas residiam com aplicadores. A caracterização sociodemográfica foi realizada com entrevista semiestruturada em visita domiciliar. Aferiu-se peso, estatura e perímetro da cintura (PC) e calculou-se o Índice de Massa Corporal (IMC) e a Relação Cintura/Estatura (RCE), para avaliação do estado nutricional. A porcentagem de gordura corporal foi avaliada pelo DEXA e realizou-se exames bioquímicos. Encontrou-se 68% com excesso de peso, 81% com excesso de gordura corporal, 78% com risco cardiovascular pelo PC e 81% pela RCE. Estarem expostas aos agrotóxicos se associou a baixos níveis séricos de monócitos (p=0,017) e a alterações no hormônio tireoidiano TSH (p=0,013). O tempo de exposição apresentou correlação positiva com os valores de triglicerídeos e VLDL. Os resultados revelam que a exposição a agrotóxicos, mesmo que de forma indireta, repercute em problemas de saúde nas mulheres rurais e que, à medida que aumenta o tempo de exposição, aumentam esses efeitos.

Dentre os resíduos oriundos do setor agropecuário, observa-se o uso potencial do esterco bovino na composição de substratos voltados produção de mudas de açaí de melhor qualidade, visto sua importância tanto econômica quanto como fator de subsistência para muitas famílias objetivou-se avaliar a produção de mudas de açaí cultivar BRS-Pará em diferentes proporções de substratos alternativos à base de esterco bovino. O experimento foi desenvolvido de março a junho de 2019, com a cultivar de açaí BRS-Pará em estufa com 70% de interceptação luminosa. Foram plantadas 72 sementes de Açaizeiro, o experimento foi conduzido em delineamento inteiramente casualizado, com 6 tratamentos, 4 repetições e 3 sementes por parcela. Os tratamentos foram consistidos em diferentes formulações de substrato alternativo: I) testemunha (100% solo); II) 20% esterco bovino + 80% mistura de solo e areia (1:1); III) 40% esterco bovino + 60% mistura de solo e areia (1:1); IV) 60% esterco bovino + 40% mistura de solo e areia (1:1); V) 80% esterco bovino + 20% mistura de solo e areia (1:1); VI) 100% esterco bovino. Constatou-se que houve pequena diferença entre os tratamentos analisados com acréscimo de substrato alternativo em comparativo com a testemunha e as demais proporções, porém o esterco bovino pode ser utilizado como um substrato na produção de mudas de açaí variedade BRS-Pará se estiver amplamente disponibilidade na região, pois permite acréscimo no desenvolvimento do sistema radicular e parte aérea, fornecendo nutrientes essenciais, maior aeração e incremento nas características biométricas das mudas. Recomenda-se o uso de substrato alternativo a base de esterco bovino na proporção de 20% de EB + 80% de solo por apresentar os melhores resultados para a maioria das variáveis analisadas.

In Brazil, forage is the main source of nutrients for ruminants, but most production systems are extensive and low amounts of inputs are used to improve soil fertility. This study aimed to evaluate the effect of nitrogen doses on dry matter yield and protein content in leaves, stems and shoots of Brachiaria brizantha cv. Marandu. The soil was fertilized with dolomitic limestone and gypsum to raise base saturation to 60% in the 0-20 cm layer and decrease exchangeable aluminum in the subsurface layer. The experimentaldesign was the randomized blocks with four replications, and the plots were five meters long by five meters wide. Nitrogen fertilization doses were 0 (control), 50, 100, 150, 200 and 250 kg of N ha-1, and applied on the soil surface at the beginning of the regrowth period. Phosphate and potassium fertilization of 50 kg P ha-1 and 150 kg K ha-1 were also carried out. Plants were cut thirty-seven days after fertilization. The evaluations were carried out in the central 9.0 m2 of the plot. A positive effect of nitrogen fertilization was found on all the variables assessed in the study. The effect was linear for fresh matter and dry matter accumulation in leaves + stems of Brachiaria brizantha cv. Marandu. The accumulation of dry matter in leaves + stems was 4.46 t ha-1 in the control treatment, increasing to 6.03 t ha-1 at the highest nitrogen dose. Nitrogen fertilization positively influenced the percentage accumulation of dry matter in leaves of Brachiaria brizantha cv. Marandu, achieving the equation Y= 25.529 + 0.0372x. Consequently, there was a percentage reduction in the dry matter allocated in stems. At the highest nitrogen dose, the percentage increase of dry matter in leaves was 17%. Theeffect of nitrogen fertilization on protein content in leaves, stems and leaves + stems was also found. At the highest nitrogen dose (250 kg of N ha-1), there was an increase in protein per kg of dry matter of 86.78 g, as content in the control treatment was 67.5 g kg-1, increasing to 154.3 g kg-1. In addition to increasing the yield due to dry matter accumulation in the plant and improving the bromatological quality, nitrogen fertilization also increased protein production. We should also note that there was an increase in yield and protein production per hectare with the highest dose of nitrogen fertilization.

This study aimed to evaluate the agronomic performance of 30 sorghum genotypes planted in two seasons. In the agronomic performance evaluation, 15 superior genotypes were selected and submitted to nutritive value and nutrient accumulations evaluations. The genotypes were planted on 20 December 2017 and 5 February 2018 and submitted to three and two cuts. Agronomic and nutritional characteristics were evaluated in all cuts and considered as the average values per season. The hybrids forage accumulation 6,941 kg/ha in the first and 3,370 kg/ha in the second planting season. The plant leaf proportion varied from 41.1 to 55.9% among all hybrids in the two seasons. The whole plant crude protein contents were 111 and 121 g/kg DM in the first and second planting seasons. The in vitro dry matter digestibility varied from 579 to 679 g/kg DM among all hybrids. The agronomic and nutritional characteristics were better in first compared to second planting due to better climatic conditions. The hybrids 16F26008, 16F26014 and 16F26007 had superior characteristics. The females (ATF54A*{ATF54B*[(Tx623B*ATF54B)6-1]}-263-C-1)A and (ATF54A*{ATF54B*[((Tx623B*ATF54B)6-1]}-207-C-1)A and the males TX2784 and TX2785 produced superior hybrids.

For the first time, nanoscale phases and layers of BaSi2 were obtained by implantation of Ba+ ions with an energy of E0=20-30 keV in the surface layer of Si(111). In particular, it is shown that at a dose of D~1015 cm-2 nanophases with a band gap Eg~0.85 eV are formed, and at D~1017 cm-2 a BaSi2 nanolayer with Eg=0.67 eV. The composition and structure of the barium disilicide nanostructure were investigated by light absorption spectroscopy by Auger electron spectroscopy, and the X-ray surface morphology was studied by scanning electron microscopy. The optimal modes of ion implantation and annealing for obtaining nanoscale phases and layers of BaSi2 in the near-surface region of Si have been established. Using the method of light absorption spectroscopy, the band gap and the degree of coverage of the layer with BaSi2 nanophases were estimated. It has been shown that at a dose of D≥6·1016 cm-2 the nanolayer of BaSi2. Keywords: ion implantation, nanostructure, nanophase, annealing, barium disilicide, Auger electrons, degree of coverage.

Background

Nephrotic syndrome is associated with an acquired hypercoagulopathy that is thought to drive its predisposition for venous thromboembolism. Previous studies have suggested that urinary antithrombin (AT) loss leading to acquired AT deficiency is the primary mechanism underlying this hypercoagulopathy, but this hypothesis has not been directly tested. The objectives of this study were to test the influence of AT levels on hypercoagulopathy in nephrotic syndrome patient samples and perform meta-analyses to evaluate the likelihood of AT deficiency in patients with nephrotic syndrome.

Methods

Samples from three independent nephrotic syndrome cohorts were analyzed. AT antigen and activity assays were performed using ELISA and amidolytic assays, respectively. Plasma thrombin generation, albumin, and urine protein-to-creatinine ratios were determined using established methods. Meta-analyses were performed by combining these new data with previously published data.

Results

AT levels were not consistently related to either plasma albumin or proteinuria. AT was quantitatively related to hypercoagulopathy in adult nephrotic syndrome, whereas AT activity was inconsistently associated with hypercoagulopathy in childhood nephrotic syndrome. Notably, hypercoagulopathy did not differ between patients with normal AT levels and those with levels below the threshold used to define clinical AT deficiency (<70%). Moreover, ex vivo AT supplementation did not significantly alter hypercoagulopathy in AT-deficient plasma samples. The meta-analyses demonstrated that AT deficiency was not a uniform feature of nephrotic syndrome and was more common in children than adults.

Conclusions

These data suggest that AT deficiency plays only a limited role in the mechanisms underlying the acquired hypercoagulopathy of nephrotic syndrome. Moreover, AT deficiency was not present in all patients with nephrotic syndrome and was more likely in children than adults despite the higher risk for venous thromboembolism in adults than children.

Background

Tolvaptan and octreotide–long-acting release (LAR) have renoprotective effects in autosomal dominant polycystic kidney disease (ADPKD) that are partially mediated by amelioration of compensatory glomerular hyperfiltration. We compared the effects of tolvaptan and octreotide-LAR combination therapy versus those of tolvaptan monotherapy in patients with ADPKD.

Methods

This pilot, randomized, placebo-controlled, cross-over trial primarily compared the effects of 1- and 4-week treatments with octreotide-LAR (two 20-mg i.m. injections) or placebo (two i.m. 0.9% saline solution injections) added-on tolvaptan (up to 90 and 30 mg/d) on GFR (iohexol plasma clearance) in 19 consenting patients with ADPKD referred to a clinical research center in Italy. Analyses were intention-to-treat. The local ethical committee approved the study.

Results

At 4 weeks, GFR significantly decreased by a median (interquartile range) of 3 (−1 to 5) ml/min per 1.73 m2 with tolvaptan and placebo (P=0.01) and by 7 (3–14) ml/min per 1.73 m2 with tolvaptan and octreotide-LAR (P=0.03). GFR changes during the two treatment periods differed by 2 (−5 to 14) ml/min per 1.73 m2 (P=0.28). At 1 week, GFR significantly decreased by 3 (0–7) ml/min per 1.73 m2 with tolvaptan and placebo (P=0.006) and by 10 (−6 to 16) ml/min per 1.73 m2 with tolvaptan and octreotide-LAR add-on therapy (P<0.001). GFR changes during the two treatment periods significantly differed by 3 (0–12) ml/min per 1.73 m2 (P=0.012). Total kidney volume nonsignificantly changed by 4 (−48 to 23) ml with tolvaptan and placebo (P=0.74), whereas it decreased significantly by 41 (25–77) ml with tolvaptan and octreotide-LAR (P=0.001). Changes during the two treatment periods differed by 36 (0–65) ml (P=0.01). Octreotide-LAR also attenuated (P=0.02) the aquaretic effect of tolvaptan. Treatments were well tolerated.

Conclusions

In patients with ADPKD, octreotide-LAR added-on tolvaptan reduced GFR more effectively than octreotide-LAR and placebo. Octreotide-LAR also reduced total and cystic kidney volumes and attenuated the acquaretic effect of tolvaptan.

Comparative study between the lean manufacturing versus the cleaner production
Authors: Pereira Ricardo , Hatakeyama Kazuo , Hurtado Ana Lúcia Berretta
Published: January 2023

Cost reduction, making the most of resources, whether raw materials, machines or labor, are a great challenge for organizations and their managers, which occasionally in day-to-day life do not always have their full utilization. In addition to these, there are efforts to search for increasingly ecologically correct processes and products. Coming to common sense and delivering a quality product, on time and that generates the least amount of waste and impact on the environment is the current challenge. The article shows two systems, lean manufacturing and its tools to help reduce waste, and Cleaner Production, which seeks to optimize resources in favor of the lowest impact to be generated. In addition to these, it aims to show the benefits generated by them when applied correctly. The article was developed through qualitative research, with searches carried out for case studies and articles, through exploratory and bibliographical research. Lean Manufacturing aims to highlight and eliminate all waste, whether in the productive area or in the administrative area, Cleaner Production aims to identify the generation of impacts and highlight them in the search for the elimination of generation. As a result, there is a similarity between both methodologies, but with different focuses, one more structured with defined methodologies and analysis and implementation tools, the other with step-by-step implementation, but somewhat superficial.
El pensamiento económico del Dr. Joaquín Balaguer
Authors: Montás Betances Manuel Moisés
Published: January 2023

Basado en algunos textos escritos durante el período de 1962 a 1966 y recopilados en Gerón (2014). Al respecto, este autor ubica a Balaguer dentro del pensamiento fisiocrático, cuyo accionar también entremezcla inclinaciones por elementos liberales en lo económico con algo de despotismo ilustrado en los aspectos políticos. Así, el modelo de desarrollo económico de Balaguer se resume en la combinación de políticas orientadas a la industrialización del sector agrícola, el ahorro público interno, la protección del medio ambiente y la promoción de obras para fomentar la cultura.
