Reactions from family of origin to the disclosure of lesbian motherhood via donor insemination
Most studies of planned lesbian motherhood via donor insemination (DI) have sampled lesbian mothers in individualistic societies where adults have relatively distant connection to their family of origin. Our study examined the experiences of biological and non-biological lesbian mothers in five families who had children through DI after disclosing their motherhood status to their family networks in Portugal, a familistic society. The first theme identified by thematic analysis, “But why do you want to have a child?” encapsulated the reactions of biological mothers’ family of origin to the announcement of motherhood. Disclosure was mostly met by a shocked response in the extended family, rooted in the belief that lesbian women should not have children. The second theme, “But you weren’t pregnant, how is this your child?” summarized the reactions of non-biological mothers’ family of origin to the disclosure of motherhood status as they considered refusing to recognize their grandchild in the absence of biological connection. Prejudice against lesbian-mother family formation was associated with the specific intersection of lesbianism and motherhood, but relationships between the mothers and their families were largely repaired because of familistic values
Longitudinal evaluation of hepatic osteodystrophy in children and adolescents with chronic cholestatic liver disease
Bone mass loss is a major complication of chronic cholestatic liver disease (CCD). However, the long-term impact of CCD on bone mass acquisition is unknown. We longitudinally assessed bone mineral density (BMD) and factors involved in bone remodeling in 9 children and adolescents with CCD Child-Pugh A (5 boys/4 girls) and in 13 controls (6 boys/7 girls). The groups were evaluated twice, at baseline (T0) and after 3 years (T1), when osteocalcin, deoxypyridinoline, 25-hydroxyvitamin-D, parathyroid hormone, insulin-like growth factor-I (IGF-I), and BMD (L1-L4, proximal femur and total body) were determined. Serum levels of receptor activator for nuclear factor kB ligand (RANKL) and osteoprotegerin were measured only at T1. Lumbar spine BMD was reanalyzed twice: after adjustment for bone age and to compensate for the height factor. Volumetric density was also estimated mathematically in L2-L4. The BMD of L1-L4 was lower in the CCD group (Z-score at T0: control = -1.2 ± 0.8 vs CCD = -2.2 ± 1.4, P < 0.05; T1: control = -0.7 ± 0.8 vs CCD = -2.1 ± 1.1, P < 0.05). Osteocalcin and deoxypyridinoline were similar for the two groups. The CCD group presented lower IGF-I (Z-score at T1: control = 1.4 ± 2.8 vs CCD = -1.5 ± 1.0, P < 0.05) and RANKL (control = 0.465 ± 0.275 vs CCD = 0.195 ± 0.250 pM, P < 0.05) than control. Children with compensated CCD Child-Pugh A showed early impairment of bone acquisition, with the impact being more severe in an initial phase and then tapering in a slowly progressive way. Reduction in endocrine IGF-I has a crucial role in this process
ANÃLISE DO COMPORTAMENTO DOS CONSUMIDORES DE CAFÉ NO MUNICÃPIO DE LAVRAS, MG
Reduction in coffee consumption has required from coffee organizations the development of marketing techniques so as to creating value to their product as well as reaching consumer’s satisfaction. This work aimed at identifying questions on coffee consumers’ desires, perceptions, preferences and habits in Lavras, MG. The conclusive/descriptive research model was used, by means of which primary data were gathered through personal/individual surveys using structured questionnaires. It was verified that consumers are not loyal to coffee brands and that the determining factors in theirs choices are taste, price and yelding. Packaging must feature information on production site, manufacture and expiration dates, type, product classification, as well as information on the warrant stamp, yelding and brand.marketing, satisfaction, consumer., Consumer/Household Economics,
Uso De água Residuária Da Piscicultura No Cultivo De Alface
Lettuce stands out as the main leafy vegetable consumed in Brazil, with divergence regarding adaptability to different environmental conditions, which include salinity. The objective of the work was to evaluate the response of lettuce cultivars to the use of saline wastewater from fish farming. The experiment was conducted in a completely randomized design with four replicates, in a factorial 7 × 4, corresponding to seven cultivars (Regiane, Vera, Isabela, Elisa, Amelia, Lavinia and Angelina) and four salt concentrations (1.2, 2.2, 3.2 and 4.2 dS m-1). The evaluated characteristics were: number of leaves, leaf area, crown diameter and shoot fresh and dry matter. Diluted wastewater from fish farming can be used in the preparation of solution for fertigation of lettuce. The cultivars Regiane and Elisa had higher production of leaves and leaf area, while Amélia and Angelina were the most productive in terms of biomass. The cultivars Vera, Isabela, Amélia and Angelina were more tolerant to the salinity of the fertigation solution. © 2016, Departamento de Engenharia Agricola - UFCG/Cnpq. All rights reserved.20872873
Magnetotelluric Imaging of the Lithosphere Across the Variscan Orogen (Iberian Autochthonous Domain, NW Iberia)
A new magnetotelluric (MT) survey comprising 17 MT soundings throughout a 30 km long
N30°W transect in the Iberian autochthons domain of NW Iberia (Central Iberian Zone) is presented. The
2-D inversion model shows the resistivity structure of the continental crust up to 10 km depth, heretofore
unavailable for this region of the Variscan Orogen. The MT model reveals a wavy structure separating a
conductive upper layer underlain by a resistive layer, thus picturing the two main tectonic blocks of a
large-scale D2 extensional shear zone (i.e., Pinhel shear zone). The upper layer represents a lower grade
metamorphic domain that includes graphite-rich rocks. The lower layer consists of high-grade metamorphic
rocks that experienced partial melting and are associated with granites (more resistive) emplaced during
crustal thinning. The wavy structure is the result of superimposed crustal shortening responsible for the
development of large-scale D3 folds (e.g., Marofa synform), later deflected and refolded by a D4 strike-slip
shear zone (i.e., Juzbado-Penalva do Castelo shear zone). The later contribution to the final structure of the
crust is marked by the intrusion of postkinematic granitic rocks and the propagation of steeply dipping brittle
fault zones. Our study demonstrates that MT imaging is a powerful tool to understand complex crustal
structures of ancient orogens in order to design future prospecting surveys for mineral deposits of
economic interest

Leishmania amazonensis promastigotes in 3D Collagen I culture: an in vitro physiological environment for the study of extracellular matrix and host cell interactions
Leishmania amazonensis is the causative agent of American cutaneous leishmaniasis, an important neglected tropical disease. Once Leishmania amazonensis is inoculated into the human host, promastigotes are exposed to the extracellular matrix (ECM) of the dermis. However, little is known about the interaction between the ECM and Leishmania promastigotes. In this study we established L. amazonensis promastigote culture in a three-dimensional (3D) environment mainly composed of Collagen I (COL I). This 3D culture recreates in vitro some aspects of the human host infection site, enabling the study of the interaction mechanisms of L. amazonensis with the host ECM. Promastigotes exhibited “freeze and run” migration in the 3D COL I matrix, which is completely different from the conventional in vitro swimming mode of migration. Moreover, L. amazonensis promastigotes were able to invade, migrate inside, and remodel the 3D COL I matrix. Promastigote trans-matrix invasion and the freeze and run migration mode were also observed when macrophages were present in the matrix. At least two classes of proteases, metallo- and cysteine proteases, are involved in the 3D COL I matrix degradation caused by Leishmania. Treatment with a mixture of protease inhibitors significantly reduced promastigote invasion and migration through this matrix. Together our results demonstrate that L. amazonensis promastigotes release proteases and actively remodel their 3D environment, facilitating their migration. This raises the possibility that promastigotes actively interact with their 3D environment during the search for their cellular “home”—macrophages. Supporting this hypothesis, promastigotes migrated faster than macrophages in a novel 3D co-culture model
