Estrogen Deficiency Impairs Osseointegration in Hypertensive Rats Even Treated with Alendronate Coated on the Implant Surface.

Hypertension and estrogen deficiency can affect bone metabolism and therefore increase the risk of osseointegration. Antihypertensive drugs such as losartan not only control blood pressure but also enhance bone healing. In addition, alendronate sodium is widely used to treat postmenopausal osteoporosis.

Adolescent mothers, self-care and childcare: content validation of an Event History Calendar.

Objective: To validate the content of the tool Event History Calendar Adolescent Mother: strengthening self-care and child care.

Method: Methodological study using the Delphi technique, conducted in two rounds, involving 37 nursing specialists. In data collection, from December/2019 to August/2020, a semi-structured questionnaire composed of 47 items related to the two dimensions of the tool: Self-care and Child Care was used.

Assessing the Fate of Superparamagnetic Iron Oxide Nanoparticles Carrying Usnic Acid as Chemical Cargo on the Soil Microbial Community.

In the present study we evaluate the effect of superparamagnetic iron oxide nanoparticles (SPIONs) carrying usnic acid (UA) as chemical cargo on the soil microbial community in a dystrophic red latosol (oxysol). Herein, 500 ppm UA or SPIONs-framework carrying UA were diluted in sterile ultrapure deionized water and applied by hand sprayer on the top of the soil. The experiment was conducted in a growth chamber at 25 °C, with a relative humidity of 80% and a 16 h/8 h light-dark cycle (600 lx light intensity) for 30 days.

CeO nanostructured electrochemical sensor for the simultaneous recognition of diethylstilbestrol and 17β-estradiol hormones.

A new highly sensitive, selective, and inexpensive electrochemical method has been developed for simultaneously detecting diethylstilbestrol (DES) and 17β-estradiol (E2) in environmental samples (groundwater and lake water) using a graphite sensor modified by cerium oxide nanoparticles (CPE-CeO NPs). The developed sensor and the materials used in its preparation were characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The ab initio simulation was used to evaluate the adsorption energies between both DES and E2 with the surface of the sensor.

An efficient and simple method using a graphite oxide electrochemical sensor for the determination of glyphosate in environmental samples.

Excessive and indiscriminate use of the herbicide glyphosate (GLY) leaves the environment susceptible to its contamination. This work describes the development of a simple, inexpensive, and efficient electroanalytical method using graphite oxide paste electrode (GrO-PE) for the direct determination of GLY traces in groundwater samples, soybean extracts, and lettuce extracts. Under optimal experimental conditions, the developed sensor exhibited a linear response of the peak current intensity vs.

Strengthening Self-Care and Child Care of Adolescent Mothers Through an Event History Calendar.

Purpose: To identify events and experiences of adolescent mothers relevant to their own care and the care of their children so as to support the elaboration of a future Event History Calendar (EHC) tool.

Design And Methods: Qualitative study was conducted based on the Grounded Theory, from the constructivist perspective. Data were collected through in-depth interviews with 11 Brazilian adolescent mothers.

Maternal-child nursing care for adolescent mothers: health education.

Objectives: to develop an educational intervention through a game that addresses aspects related to adolescent motherhood and child care.

Methods: this is an action research based on diagnosis, intervention and apprehension stages.

Results: the situational diagnosis was based on a literature review on adolescent motherhood and child care.

In vitro and in vivo impact assessment of eco-designed CuO nanoparticles on non-target aquatic photoautotrophic organisms.

This work has assessed the impact of copper oxide nanoparticles (CuONPs), designed via green route, toward photosynthetic apparatus on aquatic photoautotrophic organisms. In order to filling knowledge gaps, in vitro and in vivo assays were performed, using cyanobacterial phycocyanin (C-PC) from Arthrospira platensis and Lemna valdiviana plants (duckweed), respectively. Impairment in light energy transfer became evident in C-PC exposed to CuONPs, giving rise to an increase of light absorption and a suppression of fluorescence emission.

Nurse to adolescent health communication process: approach to Event History Calendar.

Objectives: comprehend the Event History Calendar components that are relevant for the nurse to adolescent communicative process, in the context of Primary Health Care.

Methods: reflective study, based on the Event History Calendar approach, in the relational, communicative, and educational dimensions.

Results: best practices for adolescent health promotion are vital and constitute a challenge to nurses.

A new simple electrochemical method for the determination of Bisphenol A using bentonite as modifier.

A simple, inexpensive, highly sensitive, selective, and novel electrochemical method was developed for determination of the Bisphenol A in samples of tap water, blood serum, and urine using a bentonite-modified carbon paste electrode. The graphite, bentonite and the working electrodes (without and chemically modified) were characterized by scanning electron microscopy, infrared absorption spectroscopy, and X-ray diffraction. The electrodes were electrochemically characterized using cyclic voltammetry, square wave voltammetry, and electrochemical impedance spectroscopy.

[Child care and health rights: perspectives of adolescent mothers].

Objective: To analyze child health care and the defense of their rights from the perspective of adolescent mothers.

Methods: An exploratory study with qualitative thematic analysis of data, based on conceptual aspects of care and the right to health, from semi-structured interviews with 20 adolescent mothers ascribed by Family Health teams.

Results: Maternal reports indicate that child health care requires responsibility and protection, with health practices that promote child advocacy.
