The maternal hormone in the male brain: Sexually dimorphic distribution of prolactin signalling in the mouse brain.
2018
Research of the central actions of prolactin is highly focused on females, but this hormone has also documented roles in male physiology and behaviour. Here, we provide the first description of the pattern of prolactin-derived signalling in the male mouse brain, employing the immunostaining of phosphorylated signal transducer and activator of transcription 5 (pSTAT5) after exogenous prolactin administration. Next, we explore possible sexually dimorphic differences by comparing pSTAT5 immunoreactivity in prolactin-supplemented males and females. We also assess the role of testosterone in the regulation of central prolactin signalling in males by comparing intact with castrated prolactin-supp…
Estudio de los factores que regulan el tamaño del cerebro y la neurogénesis adulta en un reptil, la lagartija parda (Podarcis liolepis)
2015
Estudios llevados a cabo principalmente en aves y mamíferos muestran que la neurogénesis adulta responde a la regulación de numerosos factores. En los reptiles, sin embargo, la información disponible es escasa. El objetivo principal de esta tesis consiste en identificar factores que regulan el tamaño del cerebro y la neurogénesis adulta en un reptil, la lagartija parda (Podarcis liolepis). En particular estudiamos cómo el sexo, la estacionalidad y las hormonas esteroides afectan al tamaño del cerebro y de los bulbos olfativos, y a la proliferación celular y la migración de las nuevas células en el telencéfalo de estos lagartos. Para ello, capturamos 10 machos adultos de cada sexo cada dos m…
Effects of Estrogen on Vascular Inflammation
2012
Objective— Our study aims to determine the role of time of menopause on vascular inflammation biomarkers and how it affects their modulation by estrogen and raloxifene in postmenopausal women. Methods and Results— Uterine arteries from 68 postmenopausal women were divided into 3 segments and cultured for 24 hours in tissue culture media containing 17β-estradiol (100 nmol/L), raloxifene (100 nmol/L), or vehicle. Assessment of arterial concentration of 13 inflammatory biomarkers was performed by multiplex immunobead-based assay. Aging per se has a positive correlation with the generation of several proinflammatory markers. Although short-term estradiol exposure correlates with lower expressi…
The epidemiology of anabolic-androgenic steroids use among secondary students (Valencia-Spain)
2019
The consumption of anabolic-androgenic steroids (AAS) is continuously growing in recent years among young people. The purpose of the current study was to examine the proportion of students who reported AAS use, explore other drug use among them and finally to determine the sociodemographic profile of the AAS consumption amongst a sample of students in the Valencian Region (Spain). Method. Data was taken from a self-administrated survey of a representative sample of 1,1162 Valencian students. A total of 252 schools participated in the study. Results. The findings show that 3.3% of surveyed students reported that they had consumed AAS. Males reported to take anabolic more frequently than fema…
Anabolic steroids and their effects on health: a case study of media social responsibility
2019
Anabolic steroids are among the oldest performance- enhancing drugs in sport and their use has spread into many other layers of society. The use and sale of steroids are illegal in most parts of the world, and authorities who attempt to combat trafficking in them find themselves engaged in ceaseless, yet ultimately futile efforts: traffickers are always a step ahead of them. However, an effective way to combat steroid use could be to inform people about these drugs' advantages and disadvantages. The mainstream media can play an important part in this process. They have a social responsibility to provide exhaustive information about the long-term damage caused by these substances. Do journal…

Interrelationship between reproductive hormones and acute phase proteins during estrous cycle and pregnancy in Spanish purebred broodmares
2021
Highlights • Steroid hormones and acute phase proteins in cyclic and pregnant mares were evaluated. • SAA and CRP did not discriminate cyclic and pregnant mares. • Pregnancy induced a limited acute phase response in Spanish purebred mares. • SAA, Hp and CRP were independent of E1 and P4 dynamics during pregnancy.
Le ragioni della trascrivibilità del certificato di nascita redatto all’estero a favore di una coppia same sex
2017
A partire dalla sentenza della Corte di cassazione 19599/2016 viene esaminato il tema della trascrivibilità dei certificati di nascita formati all’estero in conseguenza del ricorso di coppie same-sex a metodiche di procreazione artificiale non ammesse in Italia. In assenza di una soluzione normativa - di cui non vi è traccia nella l. 76/2016 e nei relativi decreti attuativi del febbraio 2017 - l’ammissibilità della trascrizione viene desunta e argomentata dai principi costituzionali interni e sovranazionali in materia di diritti fondamentali, filiazione e famiglia alla luce dei quali la trascrizione è ritenuta compatibile con il limite dell’ordine pubblico previsto dagli artt. 18 dpr 396/20…
Bases hormonals de la conducta prosocial: una revisió de la literatura
2016
Resumen: En los últimos años se ha intensificado el estudio de las conductas prosociales, incluyendo una mayor atención a los aspectos neuropsicobiológicos implicados en tales conductas, para entender su funcionamiento, así como para fomentarlas. Las investigaciones también pueden proporcionar una aproximación a la búsqueda de tratamientos más acertados a aquellas enfermedades en las que la cognición social se ve alterada. El objetivo principal del presente trabajo es establecer el estado actual de la cuestión, revisando la literatura publicada sobre las hormonas que influyen a la conducta prosocial, tanto en animales como en humanos. Los resultados de la investigación apuntan a la oxitocin…
Instability of misoprostol tablets stored outside the blister: a potential serious concern for clinical outcome in medical abortion.
2014
IntroductionMisoprostol (Cytotec) is recognised to be effective for many gynaecological indications including termination of pregnancy, management of miscarriage and postpartum haemorrhage. Although not licensed for such indications, it has been used for these purposes by millions of women throughout the world. Misoprostol tablets are most often packaged as multiple tablets within an aluminium strip, each within an individual alveolus. When an alveolus is opened, tablets will be exposed to atmospheric conditions.ObjectiveTo compare the pharmaco technical characteristics (weight, friability), water content, misoprostol content and decomposition product content (type A misoprostol, type B mis…
