Fear of Covid-19 and health-related outcomes: results from two Brazilian population-based studies.

Fear is a reaction that can influence multiple aspects of health and life. During the Covid-19 pandemic, there have been serious pathophysiological, social, behavioral and mental consequences that can be related to fear. This study aimed to assess the fear of Covid-19 and its association with sociodemographic, behavioral and health variables.

Maize Transformation: From Plant Material to the Release of Genetically Modified and Edited Varieties.

Over the past decades, advances in plant biotechnology have allowed the development of genetically modified maize varieties that have significantly impacted agricultural management and improved the grain yield worldwide. To date, genetically modified varieties represent 30% of the world's maize cultivated area and incorporate traits such as herbicide, insect and disease resistance, abiotic stress tolerance, high yield, and improved nutritional quality. Maize transformation, which is a prerequisite for genetically modified maize development, is no longer a major bottleneck.

Polar fraction from Parkinsonia aculeata aerial parts extract improves imbalanced metabolic profile and reduces proinflammatory interleukin levels in white adipose tissue in obese rats induced by western diet.

Ethnopharmacological Relevance: Parkinsonia aculeata L. (Cesalpineaceae) is a medium tree found in the Xingó region (semi-arid area) in Northeast of Brazil, recognised by local population as an antidiabetic agent. According information from local community, the commonly traditional preparation is prepared as an infusion of the aerial part of the plant and consumed over the day to manage diabetes-related complications.

Tobacco smoking prevalence and associated factors among the elderly in the rural area of Rio Grande/RS, Brazil.

Introduction: Although tobacco smoking prevalence in the adult Brazilian population is monitored through population-based surveys, the majority of findings come from studies undertaken in urban areas. Therefore, very little is known about tobacco smoking prevalence and associated factors among elderly people living in rural Brazilian areas. As such, this study aimed to assess tobacco smoking prevalence and associated factors among elderly people in the rural area of the municipality of Rio Grande, state of Rio Grande do Sul (RS), Brazil.

' Liberibacter asiaticus' is the most common huanglongbing-associated bacteria, being present in Asia, South, Central, and North America. Genomic approaches enabled sequencing of '. L.

The Stress-Induced Soybean NAC Transcription Factor GmNAC81 Plays a Positive Role in Developmentally Programmed Leaf Senescence.

The onset of leaf senescence is a highly regulated developmental change that is controlled by both genetics and the environment. Senescence is triggered by massive transcriptional reprogramming, but functional information about its underlying regulatory mechanisms is limited. In the current investigation, we performed a functional analysis of the soybean (Glycine max) osmotic stress- and endoplasmic reticulum (ER) stress-induced NAC transcription factor GmNAC81 during natural leaf senescence using overexpression studies and reverse genetics.

[The Hospital Real de Todos-os-Santos and its healing agents].

The article explores the actions of king Dom João II (1481-1495), who spearheaded a major assistance reform in Portugal during the late fifteenth century, when charitable institutions were grappling with a serious crisis. The king and his queen, Dona Leonor, ordered two large, modern hospitals to be built, centralizing assistance work and cementing a new assistance model. Relying on chronicles and royal decrees from the period, the article focuses on the main hospital that was built then: Hospital Real de Todos-os-Santos, located in Lisbon.

Comprehensive analysis of the endoplasmic reticulum stress response in the soybean genome: conserved and plant-specific features.

Background: Despite the relevance of the eukaryotic endoplasmic reticulum (ER)-stress response as an integrator of multiple stress signals into an adaptive response, knowledge about these ER-mediated cytoprotective pathways in soybean (Glycine max) is lacking. Here, we searched for genes involved in the highly conserved unfolded protein response (UPR) and ER stress-induced plant-specific cell death signaling pathways in the soybean genome.

Methods: Previously characterized Arabidopsis UPR genes were used as prototypes for the identification of the soybean orthologs and the in silico assembly of the UPR in soybean, using eggNOG v4.

The molecular chaperone binding protein BiP prevents leaf dehydration-induced cellular homeostasis disruption.

BiP overexpression improves leaf water relations during droughts and delays drought-induced leaf senescence. However, whether BiP controls cellular homeostasis under drought conditions or simply delays dehydration-induced leaf senescence as the primary cause for water stress tolerance remains to be determined. To address this issue, we examined the drought-induced transcriptomes of BiP-overexpressing lines and wild-type (WT) lines under similar leaf water potential (ψw) values.

The endoplasmic reticulum binding protein BiP displays dual function in modulating cell death events.

The binding protein (BiP) has been demonstrated to participate in innate immunity and attenuate endoplasmic reticulum- and osmotic stress-induced cell death. Here, we employed transgenic plants with manipulated levels of BiP to assess whether BiP also controlled developmental and hypersensitive programmed cell death (PCD). Under normal conditions, the BiP-induced transcriptome revealed a robust down-regulation of developmental PCD genes and an up-regulation of the genes involved in hypersensitive PCD triggered by nonhost-pathogen interactions.

Maternal anemia induces changes in immunological and nutritional components of breast milk.

Objective: The effects of low maternal hemoglobin levels on the immunological and nutritional components of breast milk at different maturation stages were investigated.

Methods: Colostrum, transitional and mature milk were collected from 25 mothers with normal hemoglobin levels (control group) and 18 mothers with hemoglobin levels below 11 g/dL (anemia group). Total protein, antibodies, complement proteins, fat and calorie, lipase, iron, transferrin levels, total iron-binding capacity, latent iron-binding capacity (LIBC) and transferrin saturation index (TSI) were determined.

[Family labor: desired distribution of housework and childcare between spouses].

This study investigates the desired distribution of family labor between spouses who have jobs and children of 6 years or less. This is a quantitative study developed with the participation of 92 couples living in the city of Rio Grande, state of Rio Grande do Sul Brazil. The desired distribution of housework and children care is predominantly an equal one, though the woman was seen as more responsible for the care of children.

[A history of primary health care policy in the Federal District, Brazil (1960-2007): an analysis based on the theoretical framework of historical neo-institutionalism].

This article analyzes the history of primary health care policy in the Federal District, Brazil, based on the theoretical framework of historical neo-institutionalism, identifying the predominant configurations and trends in the various administrations of the State Health Secretariat (SES-DF) from 1960 to 2007. The study indicates that the characteristics of the Federal District's health policy are dependent on the history of the original health system plans for setting priorities and goals, as well as for the health system's implementation. This influence, in addition to the centralization of decision-making processes and limited political participation, can contribute to making primary care ancillary to hospital care, thus jeopardizing its potential to produce change in the health care model.

Physisorbed water layer formation on fully hydroxylated mesoporous silicas.

Kinetic adsorption isotherms were obtained by gravimetric determination of water adsorption into fully hydroxylated mesoporous silicas using samples exposed to controlled humidity air at 22+/-2 degrees C. Twenty kinetic isotherms at several relative humidities (11, 33, 43, 51, 75, and 85%) were obtained with 11 different batches of silica using this simple procedure to obtain quantitative information on the formation of H2O adsorbates. The H2O surface concentrations obtained from the plateau data of individual kinetic adsorption isotherms at 43 and 51% RH, typically precise to about +/-1%, show that a complete monolayer is formed with negligible second-layer adsorption at these relative humidities.
