Interactions of the hormones leptin, ghrelin, adiponectin, resistin, and PYY3-36 with the reproductive system.

2006

Objective To summarize the effects of novel hormones (leptin, ghrelin, adiponectin, resistin, and PYY3-36) secreted from adipose tissue and the gastrointestinal tract that have been discovered to exert different effects on several reproductive functions, such as the hypothalamic–pituitary–gonadal axis, embryo development, implantation physiology, and clinically relevant conditions. Design A MEDLINE computer search was performed to identify relevant articles. Result(s) Leptin and ghrelin exert important roles on body weight regulation, eating behavior, and reproduction, acting on the central nervous system and target reproductive organs. As a marker of adequate nutritional stores, these horm…

Paracrine dialogue in implantation

2002

We know that the implantation process requires a functionally normal embryo at the blastocyst stage and a receptive endometrium, but also a communication link between them is needed. This paracrine dialogue between the embryo, endometrium and the corpus luteum are known to occur in ruminants and primates, more specifically endometrial-embryonic interactions have been reported in rodents and primates but not in humans. This process is a highly regulated mechanism and many molecules take part in this cross-talk. Here, we present updated information in humans on the embryonic regulation of endometrial epithelial molecules such as chemokines, adhesion and anti-adhesion molecules, and leptin dur…

Early assessment of crop yield from remotely sensed water stress and solar radiation data

2018

Soil moisture (SM) available for evapotranspiration is crucial for food security, given the significant interannual yield variability of rainfed crops in large agricultural regions. Also, incoming solar radiation (Rs) influences the photosynthetic rate of vegetated surfaces and can affect productivity. The aim of this work is to evaluate the ability of crop water stress and Rs remotely sensed data to forecast yield at regional scale. Temperature Vegetation Dryness Index (TVDI) was computed as an indicator of crop water stress and soil moisture availability. TVDI during critical growth stage of crops was calculated from MODIS products: MODIS/AQUA 8-day composite LST at 1 km and 16-day compos…

La divisa de las granadas del rey Enrique IV de Castilla y su estela posterior

2015

ABSTRACT: This study analyzes the meaning of the impresa or device of the pomegranates, with the motto « Agro dulce », utilized by Henry IV (1425-1474), of the House of Trastamara, King of Castile from 1454 until his death. By means of a review of vestiges that remain of the device, especially in architectonic elements, I postulate that the pomegranate may have been used as the family impresa of the House of Trastamara and their descendants. This, it seems, can be deduced from the pictura of the device in several personal imprese of relatives who lived in the sixteenth century. KEYWORDS: pomegranate, devices, royal clemency, Henry IV, Catholic Monarchs, Catherine of Aragon, Charles V, Phili…

Trench-parallel spreading ridge subduction and its consequences for the geological evolution of the overriding plate: Insights from analogue models a…

2018

A series of 3-D asthenospheric-scale analogue models have been conducted in the laboratory in order to simulate the arrival of a spreading ridge at the trench and understand its effect on plate kinematics, slab geometry, and on the deformation of the overriding plate. These models are made of a two-layered linearly viscous system simulating the lithosphere and asthenosphere. We reproduce the progressive decrease in thickness of the oceanic lithosphere at the trench. We measure plate kinematics, slab geometry and upper plate deformation. Our experiments reveal that the subduction of a thinning plate beneath a freely moving overriding continent favors a decrease of the subduction velocity and…

Genome-wide meta-analyses identify three loci associated with primary biliary cirrhosis.

2010

A genome-wide association screen for primary biliary cirrhosis risk alleles was performed in an Italian cohort. The results from the Italian cohort replicated IL12A and IL12RB associations, and a combined meta-analysis using a Canadian dataset identified newly associated loci at SPIB (P = 7.9 × 10−11, odds ratio (OR) = 1.46), IRF5-TNPO3 (P = 2.8 × 10−10, OR = 1.63) and 17q12-21 (P = 1.7 × 10−10, OR = 1.38).

p38 MAPK-dependent shaping of the keratin cytoskeleton in cultured cells

2007

Plasticity of the resilient keratin intermediate filament cytoskeleton is an important prerequisite for epithelial tissue homeostasis. Here, the contribution of stress-activated p38 MAPK to keratin network organization was examined in cultured cells. It was observed that phosphorylated p38 colocalized with keratin granules that were rapidly formed in response to orthovanadate. The same p38p recruitment was noted during mitosis, in various stress situations and in cells producing mutant keratins. In all these situations keratin 8 became phosphorylated on S73, a well-known p38 target site. To demonstrate that p38-dependent keratin phosphorylation determines keratin organization, p38 activity …

Influencia de los distintos tipos y parámetros del ejercicio físico sobre la calidad seminal: una revisión sistemática de la literatura

2019

Es de sobra conocida la importancia positiva de la actividad fisica correctamente prescrita en terminos de intensidad y volumen sobre diferentes alteraciones metabolicas, osteomusculares, cognitivas, etc. La infertilidad es una patologia cuya epidemiologia esta al alza por los cambios en los habitos de nuestra vida cotidiana, como la dieta inadecuada o la radiacion de las nuevas generaciones de aparatos electricos. No existen demasiadas evidencias divulgativas sobre sus causas y efectos, asi como tampoco del papel del ejercicio en la reversion de sus sintomas. Con la finalidad de obtener y sintetizar la informacion mas relevante sobre la influencia de los diferentes tipos y parametros del e…
