[Self-government processes of mothers in the context of the Brazilian Rede Cegonha Program].

The study highlights the discourses produced by mothers and professionals from the Rede Cegonha Program of the Brazilian Ministry of Health in the relationship between the body, women and public health policies on labor and birth. For this purpose, 17 semi-structured interviews were conducted and categorized in the Rede Cegonha Program, body and woman, and submitted to Foucauldian discourse analysis, processes of subjectification (resistance and subjection) and biopolitics. The data revealed: i) the relevance of a public program for this purpose; ii) the centrality of the pregnant body and the historical challenge of understanding women as mothers beyond reproduction; iii) the idea of defective bodies and resistance of those who know how to give birth; and iv) the possibilities of self-government of mothers and, consequently, the production of the self based on the experiences reported.

Correlation between risk factors that influence the development of children's language.

Purpose: To identify the most significant risk factors for child development through the application of two risk protocols, namely, the Protocol for the Identification of Risk Factors for Language and Speech Disorders (PIFRAL) and the Language Development Protocol (PDL).

Methods: A retrospective study was carried out with 194 children aged 0 to 5 years and 11 months who were participants of primary health care (PHC) in the municipality of São Paulo, Brazil, from 2016 to 2020. The database was thoroughly analyzed using R software, and the most relevant risk factors were correlated through statistical analysis, generating altered and unaltered PDL results.

Estimating the volume of the vitrectomized space using axial length: a guideline.

Purpose: The volume of the vitreous chamber varies with the size of the eye. The space created in the vitreous cavity by a vitrectomy is called the vitrectomized space. The volume of the vitrectomized space is strongly correlated with the axial length of the eye.

SAMURAI: shallow analysis of copy number alterations using a reproducible and integrated bioinformatics pipeline.

Shallow whole-genome sequencing (sWGS) offers a cost-effective approach to detect copy number alterations (CNAs). However, there remains a gap for a standardized workflow specifically designed for sWGS analysis. To address this need, in this work we present SAMURAI, a bioinformatics pipeline specifically designed for analyzing CNAs from sWGS data in a standardized and reproducible manner.

ConspectusZinc metal batteries (ZMBs) appear to be promising candidates to replace lithium-ion batteries owing to their higher safety and lower cost. Moreover, natural reserves of Zn are abundant, being approximately 300 times greater than those of Li. However, there are some typical issues impeding the wide application of ZMBs.

Buruli Ulcer Transmission: Environmental Pathways and Implications for Dermatologic Care.

Buruli ulcer (BU) is a necrotizing skin and soft tissue disease caused by Mycobacterium ulcerans that is common in hot and humid climates. Mycobacterium ulcerans is a nontuberculous mycobacterium and ubiquitous acid-fast gram-positive bacillus known to thrive in aquatic environments and water insects. The mode of transmission to humans is poorly understood and varies by geography.

Protocol for visualizing the chromatin assembly properties of epigenetic protein complexes via an HTM module-mediated artificial tethering system.

The detailed chromatin assembly processes for many epigenetic regulatory complexes are largely unknown. Here, we present a protocol utilizing heterochromatin-targeting module (HTM) module-mediated chromatin tethering followed by microscopy-based visualization to detect the recruitment priority between two components in Polycomb repressive complex 1 (PRC1). Moreover, we detail procedures for detecting the resultant histone-modifying activities of PRC1 using immunofluorescence (IF) analyses.

Room-temperature continuous-wave pumped exciton polariton condensation in a perovskite microcavity.

Microcavity exciton polaritons (polaritons) as part-light part-matter quasiparticles garner considerable attention for Bose-Einstein condensation at elevated temperatures. Recently, halide perovskites have emerged as promising room-temperature polaritonic platforms because of their large exciton binding energies and superior optical properties. However, currently, inducing room-temperature nonequilibrium polariton condensation in perovskite microcavities requires optical pulsed excitations with high excitation densities.

One-dimensional nanosonosensitizer boosted multiple branches of immune responses against MHC-deficient immune-evasive urologic tumor.

Cancer immunotherapies rely on CD8 cytolytic T lymphocytes (CTLs) in recognition and eradication of tumor cells via antigens presented on major histocompatibility complex class I (MHC-I) molecules. However, we observe MHC-I deficiency in human and murine urologic tumors, posing daunting challenges for successful immunotherapy. We herein report an unprecedented nanosonosensitizer of one-dimensional bamboo-like multisegmented manganese dioxide@manganese-bismuth vanadate (BMMBV) to boost multiple branches of immune responses targeting MHC-I-deficient tumors.

Vascularization of human islets by adaptable endothelium for durable and functional subcutaneous engraftment.

Tissue-specific endothelial cells (ECs) are critical for the homeostasis of pancreatic islets and most other tissues. In vitro recapitulation of islet biology and therapeutic islet transplantation both require adequate vascularization, which remains a challenge. Using human reprogrammed vascular ECs (R-VECs), human islets were functionally vascularized in vitro, demonstrating responsive, dynamic glucose-stimulated insulin secretion and Ca influx.

Efficient Double-Layer Evaporators with Adjustable Pores for Sustainable Solar Evaporation.

Solar-driven desalination technology is currently an important way to obtain freshwater resources. Significantly, porous materials are used as substrate materials of interface solar evaporator, and their specific impact of water transport property and thermal management during evaporation is worth exploring. In this paper, poly(vinyl alcohol) (PVA) sponges were prepared by a chemical foaming method, adjusted the PVA polymerization degree, and formaldehyde-hydroxyl ratio to regulate the pore size, and polypyrrole (PPy) was grown in situ on the surface skeleton of PVA sponge to construct a new interfacial solar evaporator (PPy/PVA) with different pore structures.

Breed and trace mineral source influence the performance of beef heifers during periods of nutrient restriction and grazing forage at early vegetative stage.

We evaluated the effects of breed and mineral source on heifer performance during periods of nutrient restriction and grazing. On day -7, ½ Angus × ½ Nelore (ANE) and Nelore (NE) heifers (12 heifers per breed; body weight, BW = 264 ± 35 kg; age = 15 ± 1 mo) were assigned to individual drylot pens to receive ad libitum Tifton 85 (Cynodon sp.) hay and white salt for 7 days.

Rhodium-Catalyzed Homogeneous Asymmetric Hydrogenation of Naphthol Derivatives.

Due to their strong aromaticity and difficulties in chemo-, regio-, and enantioselectivity control, asymmetric hydrogenation of naphthol derivatives to 1,2,3,4-tetrahydronaphthols has remained a long-standing challenge. Herein, we report the first example of homogeneous asymmetric hydrogenation of naphthol derivatives catalyzed by tethered rhodium-diamine catalysts, affording a wide array of optically pure 1,2,3,4-tetrahydronaphthols in high yields with excellent regio-, chemo-, and enantioselectivities (up to 98% yield and >99% ee). Mechanistic studies with experimental and computational approaches reveal that fluorinated solvent 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) plays vital roles in the control of reactivity and selectivity, and 1-naphthol is reduced via a cascade reaction pathway, including dearomative tautomerization, 1,4-hydride addition, and 1,2-hydride addition in sequence.

Competitive Effect of Surface Hydrophobicity-Hydrophilicity and the Number of Accessible Protons on Water-Assisted Proton Conductivity in Metal-Organic Frameworks: Dielectric σ-Relaxation Triggered by Disordered Guest Ionic Migration and Its Mechanism.

The rapid upsurge of metal-organic frameworks (MOFs) has sparked profound interest in their potential as proton conductors for proton exchange membrane fuel cells. However, proton-conducting behaviors of hydrophobic MOFs remain poorly understood compared with their hydrophilic counterparts, largely due to the absence of a microscopic phase separation structure akin to that found in Nafion membranes. Herein, we demonstrate a strategy for regulating the structures and proton conductivities of MOFs by separately incorporating hydrophobic -C(CF)- group alongside hydrophilic -O- and -SO- groups into organic ligands as linkers.

Constructing well-dispersed active phase spontaneous redox for electrochemical nitrate reduction to ammonia.

In this study, a distinctive multiple core-shell structure of Co nanoparticles inserted into N-doped carbon dodecahedron@Co hydroxide (Co/NCD@Co(OH)) was synthesized a spontaneous redox reaction between metallic Co and NO, ultimately materializing the fine dispersion and exposure of the active sites. The electronic interaction existing between the Co/NCD core and the Co(OH) shell brings a synergistic effect, conspicuously lessens the overpotential, and reinforces the yield-rate and faradaic efficiency of NH for electrochemical nitrate-ammonia conversion. This study underlines the spontaneous redox between the catalysts and substrate, rendering it as a synthetic strategy for designing genuine and well-dispersed active sites.

Metabolically stable apelin analogs: development and functional role in water balance and cardiovascular function.

Apelin, a (neuro) vasoactive peptide, plays a prominent role in controlling water balance and cardiovascular functions. Apelin and its receptor co-localize with vasopressin in magnocellular vasopressinergic neurons. Apelin receptors (Apelin-Rs) are also expressed in the collecting ducts of the kidney, where vasopressin type 2 receptors are also present.

Unified Variational Approach Description of Ground-State Phases of the Two-Dimensional Electron Gas.

The two-dimensional electron gas (2DEG) is a fundamental model, which is drawing increasing interest because of recent advances in experimental and theoretical studies of 2D materials. Current understanding of the ground state of the 2DEG relies on quantum Monte Carlo calculations, based on variational comparisons of different Ansätze for different phases. We use a single variational ansatz, a general backflow-type wave function using a message-passing neural quantum state architecture, for a unified description across the entire density range.

Molecular Angular Momentum Orientation Using Dressed States Created by Laser Radiation.

We have produced state selective molecular angular momentum orientation using dressed states created by a cw optical field. The experiment was carried out with Li_{2} molecules and a combination of left- and right-hand circularly polarized lasers. Our approach exploits the dependence of the Rabi frequency on the quantum number M, which makes it possible to achieve complete M-state selectivity and thus molecular angular momentum orientation relative to laboratory frame space-fixed axes.
