Abstract Background Physical activity and dietary intake of dairy products are associated with improved metabolic health. Dairy products are rich with branched chain amino acids that are essential for energy production. To gain insight into the mechanisms underlying the benefit of the sub-chronic effects of running and intake of milk protein supplements, we studied L ow C apacity R unner rats (LCR), a rodent exercise model with risk for metabolic disorders. We especially focused on the role of Sirtuins, energy level dependent proteins that affect many cellular metabolic processes. Methods Forty-seven adult LCR female rats sedentary or running voluntarily in wheels were fed normal chow and g…
Toxicity as prime selection criterion among SARS-active herbal medications
2021
We present here a new selection criterion for prioritizing research on efficacious drugs for the fight against COVID-19: the relative toxicity versus safety of herbal medications, which were effective against SARS in the 2002/2003 epidemic. We rank these medicines according to their toxicity versus safety as basis for preferential rapid research on their potential in the treatment of COVID-19. The data demonstrate that from toxicological information nothing speaks against immediate investigation on, followed by rapid implementation of Lonicera japonica, Morus alba, Forsythia suspensa, and Codonopsis spec. for treatment of COVID-19 patients. Glycyrrhiza spec. and Panax ginseng are ranked in …
Pyrido[2’,3’:4,5]pyrrolo[2,1-d][1,2,3,5]tetrazine-4(3H)-ones, a new class of temozolomide heteroanalogues
2009
Twelve derivatives of new ring system pyrido[2’,3’:4,5]pyrrolo[2,1-d][1,2,3,5]tetrazine were prepared in good yields by reaction of 2-diazo-3-ethoxycarbonyl-pyrrolo[3,2-b]pyridine with alkyl- or aryl-isocyanates. Nine derivatives, screened by the National Cancer Institute (Bethesda, MD) for the in vitro one dose primary anticancer assay against a panel of about 60 human tumor cell lines, showed no significant activity.
Glycerosomes: Use of hydrogenated soy phosphatidylcholine mixture and its effect on vesicle features and diclofenac skin penetration.
2016
In this work, diclofenac was encapsulated, as sodium salt, in glycerosomes containing 10, 20 or 30% of glycerol in the water phase with the aim to ameliorate its topical efficacy. Taking into account previous findings, glycerosome formulation was modified, in terms of economic suitability, using a cheap and commercially available mixture of hydrogenated soy phosphatidylcholine (P90H). P90H glycerosomes were spherical and multilamellar; photon correlation spectroscopy showed that obtained vesicles were ∼131nm, slightly larger and more polydispersed than those made with dipalmitoylphosphatidylcholine (DPPC) but, surprisingly, they were able to ameliorate the local delivery of diclofenac, whic…
Funciones protectoras de los astrocitos en la inflamación y el estrés oxidativo cerebral
2018
La enfermedad de Alzheimer (EA) es una enfermedad neurodegenerativa que se presenta con mayor prevalencia en la población anciana. Afecta a alrededor de 37 millones de personas en todo el mundo. Desde el punto de vista inmunohistoquímico, la EA se caracteriza por la presencia de placas neuríticas (con el péptido tóxico Aβ1-42, entre otros) y ovillos neurofibrilares en diversas áreas del cerebro, responsables de la pérdida neuronal, el deterioro de las conexiones sinápticas y la gliosis reactiva causando la inflamación característica de esta enfermedad. Resultados previos indican que los astrocitos son células de protección para las neuronas y que podrían proteger de la inflamación y del est…
PINK1: a critical protein kinase in the molecular mechanisms involved in Cancer and Parkinson's disease
2012
El cáncer y la enfermedad de Parkinson (PD) son dos enfermedades en las que el mecanismo pato- fisiológico final no está completamente definido. Datos epidemiológicos indican que los pacientes con PD poseen bajo riesgo de cáncer, con la excepción de melanoma maligno y cánceres de piel, tiroides y mama, lo que sugiere una conexión funcional entre PD y cáncer. Apoyando esta conexión, la desregulación de la homeostasis mitocondrial es una característica importante en la patogénesis de ambas enfermedades. Recientemente, varios genes asociados a PD, tales como Parkin, LRRK2, DJ-1, y PINK1, han sido propuestos como moduladores de procesos cancerígenos. Mutaciones en el gen de PINK1 están asociada…

Las parejas trágicas de la mitología grecolatina en la poesía del siglo de oro español
2012
En este trabajo son analizados los diferentes grados de sátira con que los principales poetas del siglo de oro español -el renacentista Garcilaso y los barrocos Lope, Góngora y Quevedo- tratan algunas de las parejas de enamorados trágicas de la mitología y la literatura grecorromanas: Píramo y Tisbe, Hero y Leandro, Apolo y Dafne, Orfeo y Eurídice, Dido y Eneas. La causticidad depende no solo del poeta, sino también del tipo de relación amorosa de la pareja. This work analyse the different degrees of satir with which the main poets of the Spanish Golden Age -the Renaissance Garcilaso and the baroques Lope, Góngora and Quevedo- treat some of the tragic couples of lovers of the mythology and …

Genetic structure and differentiation from early bronze age in the mediterranean island of sicily: Insights from ancient mitochondrial genomes
2022
Sicily is one of the main islands of the Mediterranean Sea, and it is characterized by a variety of archaeological records, material culture and traditions, reflecting the history of migrations and populations’ interaction since its first colonization, during the Paleolithic. These deep and complex demographic and cultural dynamics should have affected the genomic landscape of Sicily at different levels; however, the relative impact of these migrations on the genomic structure and differentiation within the island remains largely unknown. The available Sicilian modern genetic data gave a picture of the current genetic structure, but the paucity of ancient data did not allow so far to make p…
