The pandemic changes daily life and ways of living: technosociality and user/families experiences.

Objectives: understand the changes imposed by the COVID-19 pandemic in the daily lives of users of Primary Health Care and their families and its impact on self-care and health promotion.

Methods: this is a holistic-qualitative multiple case study, based on the Comprehensive Sociology of Everyday Life, in which 61 users participated.

Results: experiencing a new daily life in COVID-19 pandemic times, users express their feelings, adaptation to new habits and ways of living.

Professional Safety in the daily life of primary health care: grounded theory.

Objective: to understand Professional Safety in daily life in Primary Health Care.

Methods: this is a study on the Grounded Theory method and the Symbolic Interactionism theoretical framework with 82 health professionals.

Results: it presents the category "Professional Safety in Daily Life in Primary Health Care: a Grounded Theory" and two subcategories determining and conditioning Professional Safety in PHC: professional training, infrastructure, support and technical responsibility; Professional Safety: physical protection, psychological support, distress and feelings reveal the (un)safe conditions.

Preparation, Characterization and Biocompatibility Studies of Cotton Cellulose Nanofibers.

Cellulose nanofibers have mechanical properties that make them very attractive in a myriad of fields such as biomedicine, tissue engineering, biosensors, cosmetics and food packet products. To evaluate the potential health risks of airborne cellulose nanofibers, the cellulose nanofiber was prepared and characterized and then its pulmonary potential toxicity to a mouse model was studied. Cellulose nanofiber has been prepared by acid hydrolysis of cotton cellulose and characterized by transmission electron microscopy, zeta potential and X-ray diffraction analysis.

Every birth is a story: process of choosing the route of delivery.

Objective: To analyze the discourses on the choice of the route of delivery from the perspective of women and health professionals in a public network.

Method: The methodological approach is the discourse analysis. The data collection was through interviews and the treatment of the data was based on discourse analysis.

Ethos and pathos in the delivery room.

Objective: To understand the ethos and pathos in the discourses of pregnant women and healthcare professionals in the context of the delivery room.

Method: This is a qualitative and interpretative study. The research approach was discourse analysis.

The Clinical Usefulness of Sleep Studies in Children.

Sleep disordered breathing is common in children and has the potential to have a significant impact on cognition, activity and social interaction. The overnight in-laboratory polysomnography (PSG) continues to be the gold standard instrument for the investigation of sleep-disordered breathing in children. It has the ability to rule in or rule out the need for intervention for common conditions such as obstructive sleep apnoea, assess the role of sleep quality in children and adolescents with hypersomnolence, provide physiologic data in children with hypoventilation as may be seen in neuromuscular disease and assist in the assessment of children with structural airway and lung abnormalities.

The silencing suppressor (NSs) protein of the plant virus Tomato spotted wilt virus enhances heterologous protein expression and baculovirus pathogenicity in cells and lepidopteran insects.

In this work, we showed that cell death induced by a recombinant (vAcNSs) Autographa californica multiple nucleopolyhedrovirus (AcMNPV) expressing the silencing suppressor (NSs) protein of Tomato spotted wilt virus (TSWV) was enhanced on permissive and semipermissive cell lines. The expression of a heterologous gene (firefly luciferase) during co-infection of insect cells with vAcNSs and a second recombinant baculovirus (vAgppolhfluc) was shown to increase when compared to single vAgppolhfluc infections. Furthermore, the vAcNSs mean time-to-death values were significantly lower than those for wild-type AcMNPV on larvae of Spodoptera frugiperda and Anticarsia gemmatalis.

Resveratrol and analogues: a review of antioxidant activity and applications to human health.

Resveratrol has been extensively researched for its powerful antioxidant capacity and other biological effects. The number of patents involving this compound has been growing in recent years. However, the biggest problem associated with this molecule, a limited bioavailability due to its fast metabolism in the liver, has led to obtaining its analogues or derivatives.

Characterization of a novel tymovirus on tomato plants in Brazil.

A tymovirus was isolated in Brazil from tomato plants with severe symptoms of leaf mosaic and blistering. The virus was mechanically transmissible to solanaceous indicator host species. The infected plants contained icosahedral particles and chloroplasts with membrane deformations which are typical cytopathic effects caused by tymoviruses.

A silencing suppressor protein (NSs) of a tospovirus enhances baculovirus replication in permissive and semipermissive insect cell lines.

The nonstructural protein (NSs) of the Tomato spotted wilt virus (TSWV) has been identified as an RNAi suppressor in plant cells. A recombinant Autographa californica multiple nucleopolyhedrovirus (AcMNPV) designated vAcNSs, containing the NSs gene under the control of the viral polyhedrin (polh) gene promoter, was constructed and the effects of NSs in permissive, semipermissive and nonpermissive insect cells to vAcNSs infection were evaluated. vAcNSs produced more budded virus when compared to wild type in semipermissive cells.

On the use of 2,1,3-benzothiadiazole derivatives as selective live cell fluorescence imaging probes.

Newly designed 2,1,3-benzothiadiazole-containing fluorescent probes with four excited state intramolecular proton transfer (ESIPT) sites were successfully tested in live cell-imaging assays using a confluent monolayer of human stem-cells (tissue). All tested dyes were compared with the commercially available DAPI and gave far better results.

Effect of N-acetylcysteine and/or deferoxamine on oxidative stress and hyperactivity in an animal model of mania.

Studies have consistently reported the participation of free radicals in Bipolar Disorder. Administration of d-amphetamine (d-AMPH) is a relevant animal model of mania and it increases oxidative stress in rat brain. Evidences indicate that the antioxidants N-acetylcysteine (NAC) and Deferoxamine (DFX) exert protective effects in the brain.
