Characterization of melanic and non-melanic forms in domestic and peridomestic populations of Triatoma infestans (Hemiptera: Reduviidae)
(BioMed Central, 2020-02-03)BACKGROUND. Melanic (dark) morphs have been barely reported in peridomestic and sylvatic conditions for Triatoma infestans, the most important vector of Chagas disease in the Southern Cone of South America. Adults with ... -
A selective window after the food-intake period favors tolerance induction in mesenteric lymph nodes
(Nature Publishing Group, 2019-01)Biological rhythms are periodic oscillations that occur in the physiology of the organism and the cells. The rhythms of the immune system are strictly regulated and the circadian alteration seems to have serious consequences. ... -
Equine spermatozoa at optimum physiological state are selected by chemotaxis toward progesterone
(Elsevier Science Inc, 2018-07)The success of assisted reproduction techniques depends inpart on sperm quality, which influences not only fertilization butalso embryo development and implantation. In our laboratory, wedesigned the Sperm Selection Assay ... -
Thymol, alpha tocopherol, and ascorbyl palmitate supplementation as growth enhancers for broiler chickens
(Poultry Science Association, 2018-08-24)Consumer concern on the quality of products and animal welfare has greatly increased during the past decades. Dietary synthetic antibiotic products used as growth promoters have been restricted or banned in many countries. ... -
Reemergence of St. Louis encephalitis virus in the Americas
(Centers Disease Control, 2018-12)We summarize and analyze historical and current data regarding the reemergence of St. Louis encephalitis virus (SLEV; genus Flavivirus) in the Americas. Historically, SLEV caused encephalitis outbreaks in the United States; ... -
Recruiting potent membrane penetrability in tumor cell-targeted protein-only nanoparticles
(IOP Publishing, 2019-01)The membrane pore-forming activities of the antimicrobial peptide GWH1 have been evaluated in combination with the CXCR4-binding properties of the peptide T22, in self-assembling protein nanoparticles with high clinical ... -
Gabaergic pharmacological activity of propofol related compounds as possible enhancers of general anesthetics and interaction with membranes
(Humana Press, 2013-03-01)Phenol compounds, such as propofol and thymol, have been shown to act on the GABAA receptor through interaction with specific sites of this receptor. In addition, considering the high lipophilicity of phenols, it is possible ... -
Milk fat globule epidermal growth factor 8 (MFG-E8): A novel protein in the mammalian endometrium with putative roles in implantation and placentation
(W B Saunders Co Ltd, 2012-10)MFG-E8 is a novel endometrial protein with conserved functions in tissue remodeling and angiogenesis in non-uterine tissues. Our aims were: 1. To examine the presence of MFG-E8 protein in the human endometrium during the ... -

Nuclear translocation of nuclear transcription factor-κB by α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors leads to transcription of p53 and cell death in dopaminergic neurons
(American Society for Pharmacology and Experimental Therapeutics, 2003-04-01)We describe a new molecular mechanism of cell death by excitotoxicity mediated through nuclear transcription factor κB (NFκB) in rat embryonic cultures of dopaminergic neurons. Treatment of mesencephalic cultures with ... -
Sex differences in central benzodiazepine receptor densities and circulating corticosterone release after acute stress in broiler chicks
(Poultry Science Association, 2002-02-01)The purpose of the study was to determine the effect of sex on central benzodiazepine receptor (CBR) and serum corticosterone (CS) responses to an acute stressor in broiler chicks. Birds were housed in ten mixed-sex groups ... -
Lack of species-specificity in mammalian sperm chemotaxis
(Academic Press Inc Elsevier Science, 2003-03-15)Attraction of spermatozoa by way of chemotaxis to substances secreted from the egg or its surrounding cells has been demonstrated in marine species, amphibians, and mammals. This process is species- or family-specific in ... -
Experimental Guillain-Barre syndrome induced by immunization with gangliosides: Keyhole limpet hemocyanin is required for disease triggering
(Elsevier Science, 2017-06)An experimental model of Guillain-Barré Syndrome has been established in recent years. Rabbits develop disease upon immunization with a single dose of an emulsion containing bovine brain gangliosides, KLH and complete ... -
