Rac1 GTPase, a multifunctional player in the regulation of genotoxic stress response
2013
The Ras-related C3 botulinum toxin substrate 1 (Rac1) belongs to the Ras-homologous (Rho) family of small GTPases, which transduce signals from the outside to the inside of a cell. Rac1 becomes activated upon ligand binding of a variety of receptors, including receptor tyrosine kinases and heterotrimeric G-protein-coupled receptors. After GTP loading by guanine exchange factors (GEFs), GTP-bound Rac1 engages numerous effector proteins, thereby eventually regulating cell motility and adhesion, cell cycle progression through G1, mitosis and meiosis, as well as cell death and metastasis.1 Besides, Rac1 adjusts cellular responses to genotoxic agents, such as UV light and alkylating agents, by r…
Sex reversal from functional disomy of Xp: Prenatal and post-mortem findings.
2008
Translocations involving the short arms of the X and Y chromosomes are uncommon and are often associated with anomalies in gonadal development. Segmental duplications of the X chromosome interfere with the formation of the testis in patients with a 46,XY karyotype. The gene products located within the duplicated segment, when present in double dose, may affect on male sex development. We report on a fetus with karyotype 46,XY,der (14)t(X;14) (p10;p10)dn. Attached to chromosome 14 is the entire short arm of the X chromosome. Therefore, the fetus is affected with a disomy of Xp, resulting in complete male to female sex reversal, as well as other structural defects. To the best of our knowledg…
Caring for Infants and Children Following Alternative Dietary Patterns
2017
The number of people that refrain from eating meat has apparently increased. This is due to a variety of factors other than economic constraints or religious concerns, which have long been reasons for such dietetic conduct. Several reasons for adopting diets excluding meat include improved health, concerns regarding animal welfare, the use of antibiotics and hormones in livestock, and the excessive exploitation of environmental resource. Consequently, the number of children whose parents decide to follow alternative diets, such as vegetarian, vegan, macrobiotic, or fruitarian, is also growing. Clinical research regarding adults adopting such diets has expanded, and their nutritional impact …
Emprendimiento en personas con discapacidad. Un diagnóstico a través de la técnica de grupo nominal
2018
The aim of this work is to identify the dimensions and aspects that foster and / or restrict the entrepreneurial action of disabled people from a qualitative methodological perspective. The analysis was carried out by means of the nominal group technique. As a result of the analysis, this work proposes, through the work done with disabled people, a set of interventions that will reduce barriers and foster the entrepreneurship of such vulnerable group

The Institutional Determinants of Private Equity Involvement in Business Groups: The Case of Africa
2018
This study examines the governance attributes of post-IPO (initial public offering) retained ownership of private equity in business group constituent firms in contrast to their unaffiliated counterparts, in 202 newly listed firms in 22 emerging African economies. We adopt an actor centered institutional-theoretic perspective in rationalizing institutional voids and the advantages of maintained governance by both business angels (BA) and venture capital (VC) private equity. Our findings reveal private equity retain higher post-IPO ownership in business group constituents compared to unaffiliated firms and that this is inversely moderated in the context of improving institutional quality – w…
