Agonist‐induced desensitisation of β 3 ‐adrenoceptors: Where, when, and how?
2019
β3 -Adrenoceptor agonists have proven useful in the treatment of overactive bladder syndrome, but it is not known whether their efficacy during chronic administration may be limited by receptor-induced desensitisation. Whereas the β2 -adrenoceptor has phosphorylation sites that are important for desensitisation, the β3 -adrenoceptor lacks these; therefore, it had been assumed that β3 -adrenoceptors are largely resistant to agonist-induced desensitisation. While all direct comparative studies demonstrate that β3 -adrenoceptors are less susceptible to desensitisation than β2 -adrenoceptors, desensitisation of β3 -adrenoceptors has been observed in many models and treatment settings. Chimeric …
Mechanisms of beauvericin toxicity and antioxidant cellular defense
2015
Beauvericin (BEA) is a secondary metabolite produced by many species of fungus Fusarium. This study determines the injury (cell viability, cell proliferation, mitochondrial membrane potential, cell death and DNA damage) and the intracellular defense mechanisms (catalase and superoxide dismutase) in Chinese Hamster ovary (CHO-K1) cells after BEA exposure. The results obtained in this study demonstrated that BEA induces cytotoxicity in a dose- and time-dependent manner in CHO-K1 cells. Moreover, disruption in mitochondrial enzymatic activity and cell proliferation has been observed after BEA exposure, which can lead or be consequence of cell death. BEA inhibits cell proliferation by arresting…
Repeated, Intermittent Social Defeat across the Entire Juvenile Period Resulted in Behavioral, Physiological, Hormonal, Immunological, and Neurochemi…
2016
The developing brain is vulnerable to social defeat during the juvenile period. As complements of human studies, animal models of social defeat provide a straightforward approach to investigating the functional and neurobiological consequences of social defeats. Taking advantage of agonist behavior and social defeat in male golden hamster, a set of 6 experiments was conducted to investigate the consequences at multiple levels in young adulthood resulting from repeated, intermittent social defeats or “social threats” across the entire juvenile period. Male hamsters at postnatal day 28 (P28) were randomly assigned to either the social defeat, “social threat”, or arena control group, and they …
Intestinal CD36. A lipid-sensor involved in the processing of chylomicrons in rodents
2011
International audience; CD36 is a multifunctional glycoprotein which binds nanomolar concentrations of long-chain fatty acids (LCFA) and is highly expressed on the luminal surface of enterocytes. Despite of its implication in oleoylethanolamide (OEA) and chylomicron synthesis, CD36 function in small intestine remains incompletely understood. Our in vivo data demonstrated that CD36 gene deletion in mice did not affect intestinal LCFA uptake. CD36 protein disappeared early from the luminal side of intestinal villi during the post-prandial period but only when the diet contained lipids. This drop was significant 1 h after a lipid supply and was associated with ubiquitination of CD36. Using CHO…
Determinación de la edad de un extranjero indocumentado : A propósito de la sentencia de la audiencia provincial de barcelona, de 24 de enero de 2020
2021
In recent years, immigration of minors has increased, which means that administrations establish a differentiated treatment for this sector of immigration due to the fact that they are minors; There are many aspects to take into account in these cases, including verifying the minority age, a fact that is more complicated when it comes to adolescents. This is what is analyzed by the Judgment of the Provincial Court of Barcelona, of January 24, 2020, which confirms the Resolution of the General Directorate of Attention to Children and Adolescents, which agreed to the closure of the homelessness file and the admission of the plaintiff in a Protection Center until the verification of their pers…
La tutela del menor víctima de la violencia de género : marco normativo procesal y penal
2021
The Spanish legal system provides specific protection for victims of gender violence, the paper addresses the legal situation of minors who are dependent on women victims of this type of violence. It analyses their procedural situation and, in particular, the criminal remedies for their protection. In a particular way, the aggravating circumstance of committing the act in their presence and the penalties that affect parental authority are examined.
Liquidación de la sociedad de gananciales: el caso de la adjudicación forzosa de participaciones sociales de carácter ganancial a un solo cónyuge. Co…
2021
In a liquidation of community property, the rules for the partition of the inheritance are of suppletive application. Therefore, the sentence opts for a criterion of flexible interpretation of those rules, whose application will be subject to the objective entity of the property in question. Accordingly, when the only property to be shared between the spouses is constituted by set of shares of common nature, taking into account the special circumstances of the case, such shares could be awarded to one of the spouses with the obligation to compensate the other in money, even if it requests the sale of the shares in the public auction. To this end, the request would have to impede the possibi…

DISTRIBUTION OF CARBON STARS IN THE GALAXY
2018
A search for new faint carbon (C) stars in the Polar region δ > 55o has been accomplished by obtaining objective prism spectra in the near infrared 550 -- 900 nm on images of CCD camera of Baldone Schmidt telescope of Astrophysical observatory. The positions of stars having color indices (J – K) > 1.3 mag in Two Micron All Sky Infrared Survey (2MASS) were selected to pick out suspicious carbon stars.Our survey is limited in brightness by J < 10 mag. 24 new carbon stars were found and their characteristics obtained. The correlative relation between Teff and spectral gradient [757 – 685] was confirmed. Such characteristics as Teff, distance from the Sun, absolute Mk were obtained…
Integration of immigrants into a new culture is related to poor sleep quality.
2008
Abstract Background This article reports on the relationship between cultural influences on life style, coping style, and sleep in a sample of female Portuguese immigrants living in Germany. Sleep quality is known to be poorer in women than in men, yet little is known about mediating psychological and sociological variables such as stress and coping with stressful life circumstances. Migration constitutes a particularly difficult life circumstance for women if it involves differing role conceptions in the country of origin and the emigrant country. Methods The study investigated sleep quality, coping styles and level of integration in a sample of Portuguese (N = 48) and Moroccan (N = 64) im…
