Satisfação familiar, apoio familiar e conflito trabalho-família em uma amostra de trabalhadores chilenos
It is analyzed the relationship between family satisfac- tion, family support and work-family conflict in a sam- ple of Chilean workers. A 128 technical workers and professionals between 20 and 49 years, from two cities in the region of maule (Chile) it was administered three instruments to measure variables related. It is noted that both family support and family satisfaction are variables that are related (r = 0.470, p = 0.001), therefore can be used together and both are in turn related to work-family conflict. In undertaking the study of regression was found that family support and family satisfaction are predictors of work-family conflict (β= –0.386; t[91] = –4.698; p<0.001) significantly and negatively associated with work-family conflict (r = –0.684, p = 0.001), is that higher levels of support and family satisfaction, lower the levels of work-family conflict.Se analiza la relación existente entre satisfacción familiar, apoyo familiar y conflicto trabajo-familia en una muestra de trabajadores del comercio mayorista chileno, controlando variables sociodemográficas.

C-Low Threshold Mechanoafferent Targeted Dynamic Touch Modulates Stress Resilience in Rats Exposed to Chronic Mild Stress.
Affiliative tactile interactions buffer social mammals against neurobiological and behavioral effects of stress. The aim of the present study was to investigate the cutaneous mechanisms underlying such beneficial consequences of touch by determining whether daily stroking, specifically targeted to activate a velocity/force tuned class of low-threshold c-fiber mechanoreceptor (CLTM), confers resilience against established markers of chronic unpredictable mild stress (CMS). Adult male Sprague Dawley rats were exposed to two weeks of CMS. Throughout the CMS protocol, some rats were stroked daily, either at CLTM optimal velocity (5cm/s) or outside the CLTM optimal range (30cm/s). A third CMS exposed group did not receive any tactile stimulation. The effect of CMS on serum corticosterone levels, anxiety- and depressive-like behaviors in these three groups was assessed in comparison to a control group of non-CMS exposed rats. While stroking did not mitigate the effects of CMS on body weight gain, CLTM optimal velocity stroking did significantly reduce CMS induced elevations in corticosterone following an acute forced-swim. Rats receiving CLTM optimal stroking also showed significantly fewer anxiety-like behaviors (elevated plus-maze) than the other CMS exposed rats. In terms of depressive-like behavior, while the same velocity specific resilience was observed in a forced-swim test (FST) and social interaction test both groups of stroked rats spent significantly less time interacting than control rats, though they also spent significantly less time in the corner than non-stroked CMS rats. Together, these findings support the theory CLTMs play a functional role in regulating the physiological condition of the body
The ventilation effect on stator convective heat transfer of an axial-flux permanent-magnet machine
This paper investigates the effect of the inlet configuration on cooling for an air-cooled axial-flux permanent-magnet (AFPM) machine. Temperature rises in the stator were measured and compared with results predicted using computational fluid dynamic (CFD) methods linked to a detailed machine loss characterization. It is found that an improved inlet design can significantly reduce the stator temperature rises. Comparison between the validated CFD model results and the values obtained from heat transfer correlations addresses the suitability of those correlations proposed specifically for AFPM machines

Genetic Dissection of Strain Dependent Paraquat-induced Neurodegeneration in the Substantia Nigra Pars Compacta
The etiology of the vast majority of Parkinson's disease (PD) cases is unknown. It is generally accepted that there is an interaction between exposures to environmental agents with underlying genetic sensitivity. Recent epidemiological studies have shown that people living in agricultural communities have an increased risk of PD. Within these communities, paraquat (PQ) is one of the most utilized herbicides. PQ acts as a direct redox cycling agent to induce formation of free radicals and when administered to mice induces the cardinal symptoms of parkinsonism, including loss of TH+-positive dopaminergic (DA) neurons in the ventral midbrain's substantia nigra pars compacta (SNpc). Here we show that PQ-induced SNpc neuron loss is highly dependent on genetic background: C57BL/6J mice rapidly lose ∼50% of their SNpc DA neurons, whereas inbred Swiss-Webster (SWR/J) mice do not show any significant loss. We intercrossed these two strains to map quantitative trait loci (QTLs) that underlie PQ-induced SNpc neuron loss. Using genome-wide linkage analysis we detected two significant QTLs. The first is located on chromosome 5 (Chr 5) centered near D5Mit338, whereas the second is on Chr 14 centered near D14Mit206. These two QTLs map to different loci than a previously identified QTL (Mptp1) that controls a significant portion of strain sensitivity to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), suggesting that the mechanism of action of these two parkinsonian neurotoxins are different
Long-term outcomes of the global tuberculosis and COVID-19 co-infection cohort
Background: Longitudinal cohort data of patients with tuberculosis (TB) and coronavirus disease 2019 (COVID-19) are lacking. In our global study, we describe long-term outcomes of patients affected by TB and COVID-19. Methods: We collected data from 174 centres in 31 countries on all patients affected by COVID-19 and TB between 1 March 2020 and 30 September 2022. Patients were followed-up until cure, death or end of cohort time. All patients had TB and COVID-19; for analysis purposes, deaths were attributed to TB, COVID-19 or both. Survival analysis was performed using Cox proportional risk-regression models, and the log-rank test was used to compare survival and mortality attributed to TB, COVID-19 or both. Results: Overall, 788 patients with COVID-19 and TB (active or sequelae) were recruited from 31 countries, and 10.8% (n=85) died during the observation period. Survival was significantly lower among patients whose death was attributed to TB and COVID-19 versus those dying because of either TB or COVID-19 alone (p<0.001). Significant adjusted risk factors for TB mortality were higher age (hazard ratio (HR) 1.05, 95% CI 1.03-1.07), HIV infection (HR 2.29, 95% CI 1.02-5.16) and invasive ventilation (HR 4.28, 95% CI 2.34-7.83). For COVID-19 mortality, the adjusted risks were higher age (HR 1.03, 95% CI 1.02-1.04), male sex (HR 2.21, 95% CI 1.24-3.91), oxygen requirement (HR 7.93, 95% CI 3.44-18.26) and invasive ventilation (HR 2.19, 95% CI 1.36-3.53). Conclusions: In our global cohort, death was the outcome in >10% of patients with TB and COVID-19. A range of demographic and clinical predictors are associated with adverse outcomes

Encuesta de carne bovina orientada a los hábitos de consumo y atributos de importancia de compra de los consumidores
Existe una gran cantidad de factores o comportamientos que influyen en la decisión de
compra de carne de un consumidor desde aspectos psicológicos y sensoriales hasta los
relacionados con el marketing.En este último aspecto el precio suele ser uno de los
factores más incidentes en la decisión de compra. No obstante, en los últimos años el
origen ha tomado relevancia, sobre todo en países europeos por la demanda de
productos con denominación de origen. Atributo que en Chile se empieza a apreciar cada
vez más en un segmento de consumidores. En este sentido, el objetivo del trabajo fue
evaluar los atributos de importancia de compra de los consumidores de carne bovina.Para
ello, se realizó una encuesta a 673 consumidores en Chile, de las cuales 400 fueron de
forma presencial en las ciudades de Santiago, Valdivia, Osorno y Puerto Montt mientras
que 273 se realizaron de manera on linea nivel nacional.Los requisitos para participar
fueron ser mayor de 18 años, consumir carne y participar en la decisión de compra de
carne bovina en el hogar. La encuesta presentó 11 preguntas cerradas, 11 de verdadero y
falso y preguntas de información personal.Los resultados señalan que los consumidores
compran mayoritariamente carne bovina en supermercadosenvasada al vacío (44,3%) y
en la sección de carnicería (15,1%).Un 28,7% compra en carnicerías tradicionales y un
segmento más pequeño lo realiza en tiendas especializadas (8%). En relación al origen,
los consumidores a veces compran carne nacional y a veces importada (48,4%). La
compra de carne importada se explica principalmente porque es más barata (30,4%) y
porque se encuentra con más facilidad (29%). Por otro lado, un 30,2%prefiere sólo carne
nacional. Asimismo, al plantearle a los consumidores una compra imaginaría de lomo
nacional a diferentes precios (11.700) y producidos con distinta alimentación
(grano – pradera), los encuestados se inclinaron (73,7%) por el lomo a 11.700 también alimentado a pradera (16,8%).
Finalmente, un 27,2% de los consumidores ha escuchado hablar del novillo de Osorno y
un 28,1% lo asocia a un tipo de carne. El precio y disponibilidad de carne sigue siendo
uno de los parámetros más importantes para el consumidor. Sin embargo, existe un
segmento de consumidores que prefiere la carne nacional proveniente de animales
alimentados a pradera y que, además, asocia a Osorno como una marca importante de
calidad de carnePublishe
