A entrega de um filho em adoção e as vicissitudes de ser mãe

This study aimed to investigate the feelings and experiences of motherhood of a woman who delivered two daughters for adoption. Furthermore, investigate their experiences in relation to her other children not delivered and with the condition of being a mother in this context. Using a semi-structured interview, we conducted a single case study, qualitative, through clinical report. The main results indicated the social and emotional vulnerability of the participant as an important influence on the delivery and a differentiation between children who remained in their care and daughters delivered for adoption. It was also noted the maternal role strongly related to maternal care and the different emotional reactions to experiences of delivery. We conclude the relevance of providing space for these mothers elaborate their stories, beyond the need for public policies that give legal and emotional support to mothers/families who wish to make delivery of children

Effects of leaf removal and shoot trimming on physiological and agronomic characteristics of Syrah grapevine in Northeast Brazil: preliminary results.

The São Francisco Valley, Northeast Brazil, is one of the most important wine regions with tropical conditions in the world. lt is located between parallels 8 and 1OoS, with an average annual temperature of 26.5 OC and 3,000 hours of sunshine per year. This work shows preliminary results on physiological and agronomic characteristics of Syrah vines.subjected to the practices of leaf removal and shoot trimming. The physiological and agronomical characteristics evaluated were the following: mass of cluster, mass of canes after pruning, mass of fresh and dry leaves, net photosynthesis (An), stomatal conductance (gs), intrinsic water use eficience (WUEi), leaf area (LA) and specific leaf area (SLA). The treatments did not show difJerences related to net photosynthesis (An), stomatal conductance (gs) and intrinsic water use ejJiciency (WUEi). The initial measurements of leaf area showed no difJerence between treatments. The individual leaf area was initially a.ffected by treatments, but during ripening these e.ffects were not revealed in the experimento Reverse e.ffects were observed for specific leaf area, which proved not to be a.ffected by treatments during the immature cluster phenological phase. The studies should be continued for three more seasons .in order to understand how the canopy management of Syrah, growing in a tropical environment, can injluence the agronomical and physiological plant behavior, and the implications for the quality of grapes and wines

Effects of Isometric Handgrip Training in Patients With Peripheral Artery Disease: A Randomized Controlled Trial

BackgroundMeta‐analyses have shown that isometric handgrip training (IHT) can reduce brachial systolic and diastolic blood pressure (BP) by >6/4 mm Hg, respectively. However, whether IHT promotes these effects among patients with peripheral artery disease, who exhibit severe impairment in cardiovascular function, is currently unknown. This study aimed to evaluate the effects of IHT on the cardiovascular function of patients with peripheral artery disease. Methods and ResultsA randomized controlled trial with peripheral artery disease patients assigned to either the IHT or control group was conducted. The IHT group performed 3 sessions per week, for 8 weeks, of unilateral handgrip exercises, consisting of 4 sets of isometric contractions for 2 minutes at 30% of maximum voluntary contraction and a 4‐minute interval between sets. The control group received a compression ball in order to minimize the placebo effects, representing sham training. The primary outcome was brachial BP. The secondary outcomes were central BP, arterial stiffness parameters, cardiac autonomic modulation, and vascular function. The IHT program reduced diastolic BP (75 [10] mm Hg preintervention versus 72 [11] mm Hg postintervention), with no change in the control group (74 [11] mm Hg preintervention versus 74 [11] mm Hg postintervention), with this between‐group difference being significant (P=0.04). Flow‐mediated dilation improved in the IHT group (6.0% [5.7] preintervention versus 9.7% [5.5] postintervention), with no change in the control group (7.6% [5.5] preintervention versus 7.4% [5.1] postintervention), with this between‐group difference being significant (P=0.04). There was no change in other measured variables over the intervention period. ConclusionsIHT reduced brachial diastolic BP and improved local vascular function in patients with peripheral artery disease

Accurate mass-radius ratios for Hyades white dwarfs

We use the ESPRESSO spectrograph at the Very Large Telescope to measure velocity shifts and gravitational redshifts of eight bona fide Hyades white dwarfs, with an accuracy better than 1.5 percent. By comparing the gravitational redshift measurements of the mass-to-radius ratio with the same ratios derived by fitting the \textit{Gaia} photometry with theoretical models, we find an agreement to better than one per cent. It is possible to reproduce the observed white dwarf cooling sequence and the trend of the mass-to-radius ratios as a function of colour using isochrones with ages between 725 and 800 Myr, tuned for the Hyades. One star, EGGR\,29, consistently stands out in all diagrams, indicating that it is possibly the remnant of a blue straggler. We also computed mass-to-radius ratios from published gravities and masses, determined from spectroscopy. The comparison between photometric and spectroscopic stellar parameters reveals that spectroscopic effective temperature and gravity are systematically larger than the photometric values. Spectroscopic mass-to-radius ratios disagree with those measured from gravitational redshift, indicating the presence of systematics affecting the white dwarf parameters derived from the spectroscopic analysis.Comment: MNRAS, accepted for pubblicatio
