Neuronal SIRT1 regulates metabolic and reproductive function and the response to caloric restriction
(Endocrine Society, 2018-12)
Sirt1 is a NAD-dependent class III deacetylase that functions as a cellular energy sensor. In addition to its well-characterized effects in peripheral tissues, emerging evidence suggests that neuronal Sirt1 activity plays ...
Comportamiento sexual de Alpaida veniliae (Araneae: Araneidae)
(Universidad de Costa Rica, 2012-09)
Studies in transgenic soybean cropsin Buenos Aires province, Argentina, revealed that Alpaida veniliae is one of the most abundant species in the guild of orb web spiders. This species is an effective natural enemy of ...
Geographical parthenogenesis in the brown alga Scytosiphon lomentaria (Scytosiphonaceae): Sexuals in warm waters and parthenogens in cold waters
(Wiley Blackwell Publishing, Inc, 2021-08-20)
Geographical parthenogenesis, a phenomenon where parthenogens and their close sexual relatives inhabit distinct geographical areas, has been considered an interesting topic in evolutionary biology. Reports of geographical ...
Plant Oil Valorization by Cross-Metathesis Reactions: Synthesis of Fine Chemicals From Methyl Oleate
(Planta Piloto de Ingeniería Química, 2020-02)
This work studies the production of high-value compounds by the cross-metathesis of methyl oleate (MO) with ethylene, cinnamonitrile and cinnamaldehyde using the 2nd generation Hoveyda-Grubbs complex (HG) as catalyst, ...
Morphology and physiology of the olfactory system of blood-feeding insects
(Elsevier, 2014-04)
Several blood-feeding (hematophagous) insects are vectors of a number of diseases including dengue, Chagas disease and leishmaniasis which persistently affect public health throughout Latin America. The vectors of those ...

The boll weevil, Anthonomus grandis grandis Boheman, is the most destructive cotton pest in the Western Hemisphere. In 1993, the pest was reported in Argentina, and in 1994 boll weevils were captured in cotton fields in ...
Gland composition in sexually dimorphic skin structures of two species of Hylid frogs: Plectrohyla guatemalensis and Ptychohyla hypomykter
(Brill Academic Publishers, 2019-06)
Secondary sexual characters form a diverse group of traits widely spread in amphibians. Within anurans, the Hylini tribe represents an interesting group to examine the evolution of this type of characters because it has ...
Synthesis and secretion of volatile short-chain fatty acids in Triatoma infestans infected with Beauveria bassiana
(Wiley Blackwell Publishing, Inc, 2018-09)
Physically disturbed Triatoma infestans (Hemiptera: Reduviidae) adults, as well as adults of other Chagas' disease vectors, secrete a mix of volatile organic compounds (VOCs) with alarm and possible sexual and defence ...
The molecular sensory machinery of a Chagas disease vector: Expression changes through imaginal moult and sexually dimorphic features
(Nature Publishing Group, 2017-01)
The triatomine bug Rhodnius prolixus is a main vector of Chagas disease, which affects several million people, mostly in Latin-America. Host searching, pheromone communication, and microclimatic preferences are aspects of ...
Effects of starvation on the olfactory responses of the blood-sucking bug Rhodnius prolixus
(Elsevier, 2013-07)
Blood-sucking insects use olfactory cues in a variety of behavioral contexts, including host-seeking and aggregation. In triatomines, which are obligated blood-feeders, it has been shown that the response to CO2, a ...
