Los estilos educativos de los padres y la competencia psicosocial de los adolescentes

This study examined the relationship between parenting styles and adolescents' psychosocial competence. Parents of 372 students between 11 and 15 years old were classified according to the student perception in four groups: pemissive, authoritative, authoritarian and neglectful. Several aspects related to the students' psychosocial competence were assessed through self-report measures. Results showed that both adolescents perceiving their parents as permissive and adolescents perceiving their parents as authoritative obtained the highest scores in perceived social competence and self-esteem. Moreover, their behavior in the classroom was more positive, and they were less rejected by their  classmates. These jindings are discussed in tems of the dimensions of acceptance and control underlying rhe various parenting styles.Este estudio analiza las relaciones entre los estilos educativos de los padres y algunas variables relacionadas con la competencia psicosocial de los adolescentes.

Blood\u27s Concentration of Lead and Arsenic Associated with Anemia in Peruvian Children

This exploratory, descriptive cohort study (N = 60) determined lead (Pb) and arsenic (As) blood concentrations in Peruvian children and their association with hematological parameters of iron-deficient anemia (IDA) and anthropometric measurement. The mean age of children was 10.8 months (SD = 4.7) and ranged from 3 to 24 months old. Anemia (Hb levels below 10.5 g/dL) was found in 20% of this cohort. Additionally, microcytosis (MCV \u3c 70 fL) was present in 54%, and hypochromia (MCH \u3c 23 pg) in 42% of the group of children. Chi-square analysis showed that 88% of the children with anemia also had microcytosis and hypochromia (p \u3c 0.001). Pb and As were detected in 100% of the infants’ blood samples, and the concentrations were significantly higher in older infants than in younger ones. Pb and As were not associated with the sex, anthropomorphic parameters, or infant hemogram changes. Infants who received iron supplementation were 87% less likely to have low Hb compared with those who did not (OR = 0.13, 95% CI = 0.02–0.88, p = 0.04). Herbal tea intake was significantly associated with microcytosis and hypochromia. Our finding uncovered that hematological parameters for anemia are modified in Peruvian children with high levels of microcytosis and hypochromia. Concentrations of Pb and As were above method detection limits in all Peruvian children, but these were not associated with IDA or anthropometric measurements. A large study, including other variables, would benefit from allowing a more complex model predicting anemia in Peruvian children

Aldehyde Dehydrogenase 3 Is an Expanded Gene Family with Potential Adaptive Roles in Chickpea

Legumes play an important role in ensuring food security, improving nutrition and enhancing ecosystem resilience. Chickpea is a globally important grain legume adapted to semi-arid regions under rain-fed conditions. A growing body of research shows that aldehyde dehydrogenases (ALDHs) represent a gene class with promising potential for plant adaptation improvement. Aldehyde dehydrogenases constitute a superfamily of proteins with important functions as ‘aldehyde scavengers’ by detoxifying aldehydes molecules, and thus play important roles in stress responses. We performed a comprehensive study of the ALDH superfamily in the chickpea genome and identified 27 unique ALDH loci. Most chickpea ALDHs originated from duplication events and the ALDH3 gene family was noticeably expanded. Based on the physical locations of genes and sequence similarities, our results suggest that segmental duplication is a major driving force in the expansion of the ALDH family. Supported by expression data, the findings of this study offer new potential target genes for improving stress tolerance in chickpea that will be useful for breeding programs

Flow of sugar and grains of rice from a hole in the bottom of cylinder

O fluxo de materiais granulares é pouco discutido nos livros de física básica, apesar de que sistemas de grãos estão muito presentes na vida cotidiana. Este trabalho mostra o desenvolvimento de um sistema experimental relativamente simples para estudar a vazão de grãos de arroz e de açúcar. O aparelho é constituído por um silo cilíndrico com uma abertura circular no fundo e uma balança. A balança é conectada a um computador para monitorar a massa como função do tempo dos grãos que saem do silo. Foram realizadas medidas para diferentes diâmetros da abertura de saída do silo e diferentes alturas iniciais da coluna de grãos. Para fins didáticos, o mesmo sistema foi usado para medir a vazão de água. Os resultados claramente ilustram as diferenças entre os dois tipos de fluidos e podem ser facilmente reproduzidos em sala de aulas.In basic physics books practically anything is discussed about the flux of granular materials, even though grains systems are widely present in the everyday life. In this work was developed a relatively simple experimental system to study the flow of rice and sugar grains out of a cylindrical silo with a circular aperture at the bottom. Measurements were repeated at different diameters of the circular holes and different initial heights of the grains column. For didactic motivations, the same system was used to measure the flow of water. The results clearly illustrate the differences between the two kinds of fluids and can be easily replicated in the classroom

Enfermos crónicos domiciliarios: valoración integral físico-cognitiva y caídas durante 3 años de seguimiento

ObjectiveTo assess the physical and cognitive capacity of chronically ill homebound patients, and the falls they suffered during three years of monitoring.DesignDescriptive, longitudinal study.Setting«Raval Nord» Health District, Barcelona.Patients and other participantsAll the 243 homebound chronic patients registered in the home care programme in May 1996 (67% women, average age 84).Measurements and main resultsAfter three years 16% had gone into an old people's home, 9% had moved house and 38% had died. The probability of not continuing in the programme after three years monitoring was related to less autonomy, presence of comorbidity, and worse cognitive capacity (p < 0.05). Of the 90 patients (37%) who remained active in May 1999, 41% showed disorders on the Short Portable Mental Status Questionnaire (SPMSQ), with a significant relationship to greater age, less autonomy and the presence of comorbidity. Numerous alterations in analysis (21.6%) and linked illnesses (18.9%) were found in the patients with cognitive deterioration. 42% of the patients active in May'99 had fallen during the monitoring period. 10% of the falls involved fractures. The number of falls was higher when there was visual-auditory loss, consumption of psychiatric drugs or absence of use of orthopaedic aids. There was also a greater probability of falls in patients who only had a part-time carer (p < 0.05).ConclusionsIt is important to assess the autonomy, cognitive capacity and comorbidity of homebound chronic patients when monitoring them. Likewise, cognitive disorders and falls must be properly weighed, as they are common in this class of patient

Force–velocity profiles in CrossFit athletes: A cross-sectional study considering sex, age, and training frequency

Introduction: The force–velocity profile has been analysed previously in different sports modalities; nevertheless, it has not been analysed in CrossFit. Objective: The aim of this study was to report neuromuscular characteristics of CrossFit athletes using their individual force-velocity profile, investigating differences according to sex, age, and training frequency. Materials and Meth-ods: 72 males (33.17 ± 6.86 years; BMI: 25.93 ± 3.64 kg/m2) and 18 females (30.11 ± 6.92 years; BMI: 23.53 ± 3.98 kg/m2) participated in this study. The force-velocity profile was calculated using Samo-zino’s method. Furthermore, neuromuscular characterization was completed with a squat jump and three drop jumps (20, 30, and 40 cm). Results: Regarding sex, significant differences in all analysed mechanical variables (p < 0.001) were found except for the theoretical maximal force (p = 0.944). No significant differences were found between age groups. Considering training frequency, athletes who train more than 5 days per week showed higher performance in all analysed mechanical variables (p < 0.05). Conclusion: CrossFit athletes have a force-velocity profile more oriented towards velocity than force. Males and females have different neuromuscular characteristics, also neuromus-cular improvements can be achieved at any age. Moreover, higher neuromuscular performance is developed with a training frequency of 5 days or more per week

A los 3 años un 16% ha ingresado en una residencia, un 9% se ha trasladado de domicilio, un 38% ha fallecido y un 37% permanecía activo.Mediciones y resultados principalesDe los 90 pacientes que seguían activos, un 40% había consumido algún psicofármaco en mayo de 1999. El 8% de los pacientes que refirió consumir psicofármacos lo hacía por automedicación. El grupo farmacológico más consumido entre los psicofármacos era las benzodiazepinas, en un 64%. El consumo de psicofármacos fue superior en el sexo femenino (45%) y en las personas que vivían solas o en estado de viudedad (50%). El porcentaje de pacientes con consumo de psicofármacos fue superior cuando había peor grado de autonomía según el índice de Katz (67%), déficit cognitivo en el Short Portable Mental Status Questionnaire (SPMSQ) de Pfeiffer (62%) y ante la presencia de comorbilidad (56%) (p < 0,01).ConclusionesExiste un elevado consumo de psicofármacos en los pacientes crónicos domiciliarios, especialmente cuando hay deterioro físico-cognitivo y presencia de comorbilidad.ObjectiveTo assess the consumption of psychiatric drugs by chronic homebound patients.DesignDescriptive, longitudinal study.SettingRaval Nord Health District, Barcelona.Patients and other participantsAll 243 chronically ill homebound patients registered on the home care programme in May 1996. After three years 16% had gone into a home, 9% had moved residence, 38% had died, and 37% remained active.Measurements and main resultsOf the 90 patients still active, 40% took some psychiatric drug in May 1999. 8% of the patients who said they had taken psychiatric drugs did so by self-medication. The most commonly consumed pharmocological group of the psychiatric drugs were benzodiazepines at 64%. Women took more psychiatric drugs (45%), as did persons living alone or who had been bereaved (50%). The proportion of patients taking psychiatric drugs was greater when there was worse autonomy according to the Katz index (67%), a cognitive deficit on the Short Portable Mental Status Questionnaire (SPMSQ) of Pfeiffer (62%), and in the presence of comorbidity (56%) (p < 0.01).ConclusionsThere is high consumption of psychiatric drugs by chronic homebound patients, especially when there is physical-cognitive deterioration and presence of comorbidity

Rapidly Declining Body Temperature in a Tropical Human Population

Normal human body temperature (BT) has long been considered to be 37.0°C. Yet, BTs have declined over the past two centuries in the United States, coinciding with reductions in infection and increasing life expectancy. The generality of and reasons behind this phenomenon have not yet been well studied. Here, we show that Bolivian forager-farmers (n = 17,958 observations of 5481 adults age 15+ years) inhabiting a pathogen-rich environment exhibited higher BT when first examined in the early 21st century (~37.0°C). BT subsequently declined by ~0.05°C/year over 16 years of socioeconomic and epidemiological change to ~36.5°C by 2018. As predicted, infections and other lifestyle factors explain variation in BT, but these factors do not account for the temporal declines. Changes in physical activity, body composition, antibiotic usage, and thermal environment are potential causes of the temporal decline
