Introduction: Monitoring the functional capacity of older adults is fundamental, and Handgrip Strength (HGS) is a consolidated marker of functional status in this age group. This study aimed to develop equations for predicting HGS in community-dwelling older adults in Primary Health Care (PHC). Methods: It is a cross-sectional study conducted with 316 older adults, in which a Multiple Linear Regression (MLR) was performed for the right hand (R-HGS) and left hand (L-HGS). The variables sex, age, weight, knee height (KH), arm circumference (AC), triceps skinfold (TSF), and calf circumference (CC) were considered predictors because they were easily obtained in PHC and significantly related to HGS. Results: In the final models, the variables sex, age, and KH together explained more than 50 % of the HGS variation. There was agreement between the estimated and measured HGS measurements, both for right and left side. Conclusions:  It is concluded that the variability of HGS can be explained by age, sex, and KH, which are parameters simple and routinely used to evaluate older adults.
La mortalidad de párvulos y la mortalidad infantil en Cataluña (1700-1860)
Authors: Ferrer-Alós Llorenç
Published: June 2023

Hay muy pocos trabajos sobre la mortalidad infantil en Cataluña. Por ello, se pretende estudiar la mortalidad de párvulos (infantes menores de 12 años) y la mortalidad infantil (infantes menores de 1 año) a partir de una recopilación sistemática de los datos de mortalidad presentes en 243 series parroquiales de bautismos y defunciones de las parroquias de Cataluña fechadas entre 1700 y 1860. El estudio es cuantitativo y territorializado para explorar la mortalidad diferencial. Como resultado, este tipo de mortalidad fue especialmente elevado en la segunda mitad del siglo XVIII y empezó a descender en la primera mitad del siglo XIX. También, fue menos intensa en las poblaciones más pequeñas y la reducción fue más acusada en los pueblos costeros. Finalmente, se realiza una aproximación a la evolución de la mortalidad infantil en Cataluña que corrobora los datos de la mortalidad de párvulos.

Siswa yang memiliki beban kognitif intrinsic sedang cukup bisa melakukan penalaran kreatif matematis tetapi belum konsisten. Sedangkan siswa yang memiliki beban kognitif intrinsic tinggi hampir tidak dapat melakukan penalaran kreatif matematis. Sebagai kesimpulan, diperoleh bahwa semakin rendah beban kognitif intrinsic yang dialamisiswa, semakin baik kemampuan penalaran kreatif matematis yang ia miliki. Berdasarkan kesimpulan tersebut, direkomendasikan untuk melakukan penelitian yang mengacu kepada penggunaan desain pembelajaran yang tepat untuk mengembangkan kemampuan penalaran kreatif matematis siswa pada masa yang akan datang. Mathematical creative reasoning is an essential ability for students. In reality, students' mathematical creative reasoning skills tend to be problematic. One thing that is believed to affect students' difficulties in solving problems in mathematics is the intrinsic cognitive load they face. Therefore, this study aims to describe students' creative reasoning abilities regarding intrinsic cognitive load in depth. This study uses a qualitative approach with a phenomenological design. The subjects of this study were students of class VIII from one of the state Islamic junior high schools in Lima Puluh Kota Regency, West Sumatra Province, which studied the materials for flat and solid geometry. Data was collected through test and interview techniques. The study results show that students with low intrinsic cognitive load can consistently perform creative mathematical reasoning. Students with moderate intrinsic cognitive load can do creative mathematical reasoning but are inconsistent. Meanwhile, students with a high intrinsic cognitive load can almost not do creative mathematical reasoning. In conclusion, it is found that the lower the intrinsic cognitive load experienced by students, the better their creative mathematical reasoning abilities will be. Based on the conclusion, research is recommended to use suitable learning designs to develop students' mathematical creative reasoning skills in the future.

Published: June 2023

Fractures at the thoracolumbar junction are the most common traumatic spinal injuries. Advances in instrumentation for vertebral body replacement have significantly improved surgical techniques.However, the biomechanical characteristics of stabilizing surgeries have been insufficiently studied. Objective. To investigate the stressstrain state (SSS) of a mathematical finite element model of the humanthoracolumbar spine during trunk backward bending after ТhХІІ vertebra resection, considering different transpedicular fixation options. Methods. A mathematical finite element model of the humanthoracolumbar spine — ThIX‒LV vertebrae — was developed. The ТhХІІ vertebra was removed, and an interbody support and transpedicularsystem with 8 screws were implanted to simulate the postsurgical state after a ТhХІІ burst fracture with wide laminectomy, facetectomy, and corpectomy. The influence of transpedicular screw length and the presence of cross-links on the SSS of the model wasexamined. Results. The use of bicortical screws reduced stress levels in the bone elements of the model, except in the regions around the screws in the lumbar vertebrae, when compared to short screws.Installing cross-links decreased stress levels at all control points compared to models without cross-links. Specifically, in the presence of cross-links, the SSS values at the entry points of the short screwsinto the vertebral bodies of ThX, ThXI, LI, and LII were 2.3, 1.8, 1.2, and 5.0MPa, respectively, compared to 2.7, 2.0, 1.5, and 6.1 MPa in the models without cross-links. In the case of bicortical screwswithout cross-links, the stress values at the screw entry points into the pedicles of the corresponding vertebrae were 2.9, 1.5, 8.2, and 11.2 MPa, respectively, compared to 2.7, 1.5, 7.5, and 10.2 MPa in the models with cross-links. Conclusions. When the trunk is tilted backward, the use of cross-links reduces stress levels at all control points in the models, regardless of the screw length used. Bicortical transpedicular screws increase stress levels on the screws themselves and in the lumbar vertebral bodies surrounding them.

Arsenic (As) contamination in soil, water and air is an alarming issue worldwide and has serious effects on human health and environment. Arsenic is a naturally occurring element found in rocks, soil, and water, and exposure to high levels of arsenic can lead to a range of health problems. The effects of arsenic contamination can also be felt in the environment, as it can harm plants and animals and disrupt ecological systems. The major purpose of this study was to produce transgenic plants with improved tolerance to and accumulation of arsenic via transformation of arsenate reductase gene (ArsC) into tobacco genome. Transgenic plants were screen by PCR and southern blot. Further, their tolerance and accumulation to arsenic were evaluated. In the result, we have cloned, characterized, and transformed the ArsC gene from Pityrogramma calomelanos L. (PcArsC). Its phylogenetic analysis revealed 99% homology to ArsC gene in GenBank (accession number X80057.1). Moreover, Southern blot analysis showed that ArsC gene was integrated into the tobacco genome as a single-copy. These single-copy transgenic lines showed much higher tolerance to and accumulation of As than wild type, with no other phenotypes observed. These results demonstrated that Pityrogramma calomelanos ArsC gene can improve arsenic tolerance and accumulation in transgenic tobacco lines. Thus, using Pityrogramma calomelanos L. ArsC gene for genetic engineering has potential implications in the decontamination of arsenic-containing soil.

The ‘Late-Swelling’ peach is an important cultivar due to its attributes of fruit quality, such as handling ability and late harvest season. Peaches rapidly deteriorate during storage, which shortens their shelf-life. The preservation of quality traits of ‘Late-Swelling’ peach during handling and storage investigated. Fruits harvested in the early ripe stage (last week of June) were either dipped in jojoba oil (JO) 500, 1000, and 1500 ppm and salicylic acid (SA) 100, 200, and 300 ppm, then stored at 5+1 °C and 85% RH for 35 days besides 7 days as shelf-life the fruits were examined every 7 days until the end of the experiment. Positive influences were observed for JO and SA on the different chemical and physical characteristics of the peach fruits under study especially those related to storability and fruit quality. All fruits treated with JO 1500 and 1000 ppm, and SA 300 ppm maintained the fruit firmness, hº, total acidity, and ascorbic acid over the whole storage period, in addition to the lowest decay and weight loss, as well as maintaining the fruit sensory quality and decreased peroxidase [PPO] activity while increasing polyphenol oxidase [POD], catalase [CAT], and ascorbate peroxidase [APX] activities compared with the control at the end of shelf-life period. In conclusion, our results suggest using JO and SA to enhance and prolong the storability of peach fruits at 5+1 °C and 85% RH.

Authors: PIEROZZI Neiva I. , FERNANDES MOURA Mara
Published: June 2023

‘Niagara Steck’ and ‘Niagara Variegada’ are two grapevine varieties that arose spontaneously as somatic mutants of ‘Niagara Rosada’. Berries characterize ‘Niagara Steck’ at young stages exhibiting a remarkable brown reticulated structure on the epidermis which develops into a brown-bronze russet-like structure as the berries ripe. The mature berries have strongly acidic flesh. ‘Niagara Variegada’ shows notable variegation in leaves and berries. Meiotic studies were carried out to ascertain if the mutant phenotypes could be related to any change in chromosome number, structure or other irregularity. Floral buds of both varieties at different developmental stages were collected and fixed for cytological analyses. Chromosome counts at diakinesis/metaphase I showed n=19 bivalents for both varieties. Univalent, trivalent, tetravalent chromosomes or chain configuration were not recorded ruling out the possibility of any alteration in the chromosome number or structure in both mutant varieties. However, low percentages of meiotic irregularities were recorded such as chromosome stickiness, laggards, non-oriented chromosomes, precocious chromosome segregation, tetrads with one microcyte, microspore fusion, and tetrad degeneration. The total percentage of abnormalities was higher in ‘Niagara Variegada’ (19.68%) than in ‘Niagara Steck’ (14.40%) which may have contributed to a lower percentage of pollen fertility (79.80%) when compared to ‘Steck’ (90.74%). The aforementioned varieties can be propagated by hardwood cuttings and constitute an interesting option for ornamentation of home backyards, patios, and gardens with the advantage that ‘Niagara Variegada’ bearing sweet edible berries.

Published: June 2023

The effect of bio-fertilizers and super-absorbents on the modification of water-deficit stress was studied in castor. A field experiment was conducted with a split-plot design based on a completely randomized block design with three replications. The first factor included four levels (70, 100, 130, and 160 mm of evaporation pan A Class) in the main plot; the sub-factor was the application of four bio-fertilizer treatments (Azospirillum, Citrobacter, Azospirillum + Citrobacter, and control); and the superabsorbent at two levels (superabsorbent consumption and control) as a factorial was placed in the sub-plots. With the intensification of the water-deficit stress from 70 to 160 mm of evaporation, the number of seeds per plant, the 1,000-kernel weight, and the oil percentage significantly dropped. All three bio-fertilizer treatments significantly increased the number of grains, 1,000 kernel weight, and oil percentage compared to the control. Citrobacter in all four irrigation levels significantly increased the content of photosynthetic pigments, grin yield, oil yield and proline content and decreased the catalase activity and malondialdehyde content. The application of the super-absorbent under the stress condition of 160 mm significantly raised the content of chlorophyll b, soluble sugar, grain yield, oil yield, and proline compared to the control treatment. Among the combinations of bio-fertilizer and super-absorbent treatments, the highest photosynthetic pigments’ content, grain yield, and oil yield and the lowest catalase enzyme activity belonged to Azospirillum + superabsorbent consumption. However, the maximum soluble sugars and the minimum malondialdehyde content belonged to Citrobacter + superabsorbent.

Published: June 2023

‘Cabernet Sauvignon’ is a vigorous grapevine that develops herbaceous aromas in grapes. Canopy management practices can impact grapevine physiology, and as consequence the photosynthesis, fruit yield, and grape composition, and improve the quality of the fruit. Leaf removals and apical leaf removals on grapevines have been shown to reduce herbaceous aromas. However, little is known, about the effect of the use of girdling on the concentration of volatile compounds in grapes. Thus, the objective of this study was to evaluate the effect of basal leaf removal (BLR), girdling, and girdling plus cutting the apical regions of the canopy (girdling + CAC), on the concentration of volatile compounds of ‘Cabernet Sauvignon’ grapes. Fruit yield, chemical composition, and volatile compounds were analysed in all treatments. Girdling + CAC showed a reduction in grape yield, and total acidity, however, increases in total soluble solids, and fruity aromas were observed in comparison to BLR and the control (no-canopy treatment). Controls showed the highest concentration of volatile compounds related to herbaceous and unripe fruit characteristics aromas. On the other hand, BLR showed increases in volatile compounds in the grapes related to floral character. These results suggest that grapevine canopy management modifies the chemical composition of ‘Cabernet Sauvignon’ grapes, and girdling techniques and increase the fruity aromas.

Ginger (Zingiber officinale Roscoe) is an important vegetable with medicinal value. Rhizome development determines ginger yield and quality. However, little information is available about the molecular features underlying rhizome expansion and maturation. In this study, we investigated anatomy characteristics, lignin accumulation and transcriptome profiles during rhizome development. In young rhizomes, the vascular bundle (VB) was generated with only vessels in it, whereas in matured rhizomes, three to five layers of fibre bundle in the xylem were formed, resulting in VB enlargement. It indicates VB development favouring rhizome swelling. With rhizome matured, the lignin content was remarkably elevated, thus facilitating tissue lignification. To explore the regulators for rhizome development, nine libraries including ginger young rhizomes (GYR), growing rhizomes (GGR), and matured rhizomes (GMR) were established for RNA-Seq, a total of 1264 transcription factors (TFs) were identified. Among them, 35, 116, and 14 differentially expressed TFs were obtained between GYR and GGR, GYR and GMR, and GGR and GMR, respectively. These TFs were further divided into three categories. Among them, three ZobHLHs (homologs of Arabidopsis LHW and AtbHLH096) as well as one DIVARICATA homolog in ginger might play crucial roles in controlling VB development. Four ZoWRKYs and two ZoNACs might be potential regulators associated with rhizome maturation. Three ZoAP2/ERFs and one ZoARF might participate in rhizome development via hormone signalling. This result provides a molecular basis for rhizome expansion and maturation in ginger.

Published: June 2023

The paper presents the results of three different ways of storing the dried mass of hay: bulk, small bales and large roll bales, as well as the impact of three drying methods: natural in the field, artificial drying with cold air and drying with dehumidification (warm air). In the tested meadow in the first swath, the results of chemical analyses showed differences in the method of drying hay. Regarding the tested drying method, the content of dry matter (DM) had significant differences between the storage methods as well as all variants with pre-heated air drying, where the average value of DM was in the interval of 86.18-93.01%. The content of mineral substances for certain methods of preparation and drying ranged from 5.77% to 7.72% on average. The highest content of crude proteins was in all variants of artificial drying and it ranged from 98.6 to 165.7 g/kg DM and had a statistically significant difference. Both methods of artificial post-drying had a significant impact on the cellulose content (33.76% to 28.86%) compared to drying in the traditional way because postponing the mowing time increases the cellulose content. The drying method had a statistically high significant difference on the content of neutral detergent fibres (NDF) and acidic detergent fibres (ADF), while the method of storage had no major impact. Knowledge of changes in the quality of hay during the growing season is of particular importance form the aspect of ruminant nutrition and balanced rations. The amount and quality of obtained hay is significantly affected by the time of mowing, height of mowing, swath, fertilization, floristic composition and weather conditions during drying of the green mass.

The Cerro Mohinora Protected Natural Area (PNA) located in Guadalupe y Calvo, Chihuahua, Mexico has ecosystems in a good state of conservation that include trees of genera such as Picea, Abies and Pseudotsuga. The objective was to determine the willingness to pay (WTP) by the visitors through the Contingent Valuation Method (CVM) in order to conserve the environmental services (SA) provided by the area and to know their perception of the current state of the Hill. 210 surveys were carried out to simulate a hypothetical market, where they asked what is the maximum amount they would be willing to pay to preserve and/or improve the SA of the PNA. The main results show that 90.48% of the visitors gave a positive WTP, 48.57% of the visitors are local and 55.24% have a university degree. 60.48% of the visitors do ecotourism on the Hill. The main suggestion to improve the area was the maintenance of the roads (55.00%) and the provision of more environmental education (32.69%). The only variable that influenced a positive WTP and that was statistically significant was the “Perception of good ecosystem quality (PGEQ)”. The average WTP calculated was 90.48 MXN, with a minimum and maximum of 68.12 MXN and 97.60 MXN, respectively, and a standard deviation of 5.55 MXN. The WTP should be established according to the number of visitors and use of the place, considering that it currently has no cost and that most visitors are willing to pay to enter and show concern for conservation.

In this study, the traditional full/deficit irrigation and partial root drying (F-PRD) techniques with the four different amounts of irrigation (100%, 80%, 60% and 40%) were examined on Rubygem Strawberry species under controlled greenhouse conditions, in terms of yield, yield parameters, WUE, IWUE, yield response factor (ky), etc. and their possible reactions have been investigated. In the study in which fresh seedlings were used, planted on the rows in a triangular form at intervals of 20×20 cm in double rows. Irrigation applications were carried out by drip irrigation method and the amount of irrigation water in the control treatment (I100) was calculated using measurements taken from an A-Class evaporation pan. Eight irrigation treatments including four traditional irrigation (I100, I80, I60, I40) and four fixed-partial root drying (F-PRD100, F-PRD80, F-PRD60, F-PRD40) were examined within the scope of the study. In traditional irrigation (I100, I80, I60, I40) applications, both sides of the plant root zone were irrigated. However, during the entire growing season in the fixed-partial root drying (F-PRD100, F-PRD80, F-PRD60, F-PRD40) technique, one-half of the plant root zone was kept wet, and the other half was left relatively dry. The yield values were ranked as, from high to low, F-PRD100>I100>F-PRD80>I80>F-PRD60>I60>I40>F-PRD40. In irrigation treatments, the yield values obtained from I80 and F-PRD80 treatments were statistically similar (Duncan 5%) to the yield values of I100 and F-PRD100 treatments. However, it could be stated that the F-PRD80 is more advantageous. It was found that different amounts of irrigation water (100%, 80%, 60% and 40%) affects the yield and yield-related parameters obtained from the strawberry plants. In general, as the water deficit increased (in the I40 and F-PRD40 treatments), the level of negative impact also increased. As a result of the research, F-PRD80 was proposed for the cultivation of strawberries, particularly, in arid and semi-arid regions, depending on the availability of water.

Resumo As dificuldades e barreiras enfrentadas no processo de inclusão de pessoas com deficiência (PcD) nas organizações incitam o desenvolvimento de pesquisas. Este estudo compreendeu a percepção de psicólogos organizacionais sobre a inclusão de PcD em empresas. Dezoito psicólogos atuantes na área de gestão de pessoas de empresas das sete regiões do estado do Rio Grande do Sul responderam a uma entrevista individual. A média de idade dos participantes foi de 33,17 anos, atuavam em empresas de diferentes segmentos, eram predominantemente do sexo feminino e possuíam pós-graduação em áreas relacionadas. Os relatos dos psicólogos alertaram para o fato de que, em suas graduações, o conteúdo sobre deficiência humana e, especificamente, inclusão no mercado de trabalho foi escasso ou inexistente. Essa lacuna na formação, de egressos de diferentes instituições de ensino superior, é relatada desde os anos de 1990. Para esses psicólogos, barreiras atitudinais e organizacionais são frequentemente enfrentadas no processo de inclusão, tais como o despreparo das empresas, gestores e colaboradores para receber as PcD, os poucos programas voltados a uma prática efetiva de inclusão e não somente ao cumprimento da legislação, além das dificuldades dos próprios profissionais em identificar os potenciais e as limitações que a PcD apresenta e de adaptá-la de maneira correta ao trabalho. O psicólogo organizacional pode contribuir para um processo adequado de inclusão por meio de práticas, tais como treinamentos e sensibilizações, que fomentem a informação e diminuam a discriminação e as dificuldades.

Resumo Em março de 2020 a situação causada pela covid-19 foi elevada à categoria de pandemia, impactando de inúmeras formas a vida em sociedade. O objetivo deste estudo foi compreender os impactos da pandemia na atuação e saúde mental do psicólogo hospitalar, profissional que atua nos espaços de saúde e tem experienciado mais de perto o sofrimento dos doentes e dos profissionais de saúde frente à covid-19. Trata-se de um estudo exploratório-descritivo com 131 psicólogos que atuam em hospitais. Os profissionais foram convidados a participar através de redes sociais e redes de contatos das pesquisadoras, utilizando-se a técnica Bola de Neve. Foram utilizados dois questionários, disponibilizados na plataforma Google Forms, um abordando os impactos da pandemia sentidos pelos profissionais e outro referente ao sofrimento psíquico. Os dados foram analisados a partir de estatísticas descritivas e inferenciais. Foram observados impactos na atuação de quase a totalidade dos participantes, constatada a necessidade de preparação dos profissionais para o novo cenário, a percepção de pouco apoio institucional e quase metade da população estudada referiu-se a sintomas de sofrimento psíquico considerável desde o início da pandemia. É fundamental dar atenção a sinais e sintomas de sofrimento psíquico, procurando evitar o adoecimento de uma categoria profissional que se encontra na linha de frente do combate aos danos psicológicos da pandemia e cuja própria saúde mental é pouco abordada na literatura.
Percepções e Expectativas de Homens Trans Acerca dos Relacionamentos Afetivo-Sexuais Pós-Transição
Authors: Boffi Leticia Carolina , Santos Manoel Antônio dos
Published: June 2023

Resumo As identidades transmasculinas ganharam visibilidade social e acadêmica no Brasil a partir de 2010, contudo, as questões subjetivas dos homens trans ainda são pouco debatidas, em particular temas associados aos relacionamentos afetivos na experiência desses sujeitos. Este estudo qualitativo tem por objetivo identificar as percepções e expectativas dos homens trans acerca dos relacionamentos afetivo-sexuais no cenário pós-transição de gênero. Participaram da pesquisa 15 homens transexuais hormonizados, com idades entre 20 e 41 anos. A coleta de dados foi realizada por meio de entrevista semiestruturada nas modalidades presencial e on-line. Empregou-se análise temática reflexiva, que resultou em dois temas analíticos. Os resultados apontam que os homens trans, ao contrário de suas expectativas iniciais, percebem que tiveram menos oportunidades de relacionamentos afetivo-sexuais depois de sua transição de gênero. Os participantes atribuem essa dificuldade especialmente ao fato de não terem se submetido à cirurgia de redesignação sexual. O desconforto é acentuado por sua materialidade corpórea divergente da cisnormatividade, sistema regulador que associa pessoas pertencentes ao gênero masculino à presença de um pênis. Outra fonte de desconforto é o repúdio social, que alimenta a abjeção, exotização e fetichização dos corpos transmasculinos. Também são descritas as especificidades do relacionamento dos homens trans com mulheres cisgênero, heterossexuais e lésbicas. Os resultados evidenciam que a fixação persistente no genital, como referente e signo determinante do gênero e da sexualidade, modula e regula a busca e o encontro de parceira(o) íntima(o).

Genetic polymorphisms in the vitamin D receptor (VDR) may influence the biological effects of vitamin D and increase a person's susceptibility to cancer. Previous studies have shown that different ethnic groups exhibit varying frequencies of the VDR gene variants TaqI, ApaI, FokI, and BsmI. However, the allelic distribution of these VDR polymorphisms in the Saudi population of Ha'il region is not sufficiently explored. In this study, efforts were made to ascertain the frequency of VDR polymorphisms in the Saudi population of Ha'il region, and then comparison was made for VDR polymorphism rates with other populations of the world. Allele and genotype frequencies of VDR TaqI, ApaI, BsmI and FokI gene was determined. The frequency distribution for the variant allele of VDR TaqI, ApaI, BsmI and FokI was found to be 70, 33, 50 and 25%, respectively. A significant frequency distribution was found for VDR-TaqI, ApaI and FokI variants in comparison with other populations of the world. Whereas, almost all of the studies dealing with VDR-FokI failed to show substantial difference while comparing with the data reported from the population of Ha'il region of Saudi Arabia. A significant pattern in the frequency of VDR gene variations have been found in the Saudi population of Ha'il region, which may be attributed to ethnic variance. The understanding of the worldwide distribution of VDR markers could help with high-risk screening of those who are exposed to environmental hazards and people of Ha'il region, who are predispose to cancer.
