Revista de la Sociedad Entomol?3gica Argentina , 2007,
Abstract: nests of four species of hirundinidae that nest in argentina were prospected for cimicidae. caminicimex furnarii (cordero & vogelsang), a parasite of furnarius rufus (gmelin) (furnaridae) (?oven bird?) and passer domesticus (l.) (ploceidae) (?house sparrow?) was found in nests of three species of hirundinidae: progne chalybea (gmelin) (?gray-breasted martin?), progne elegans baird (?southern martin?) and hirundo rustica erythrogaster boddaert (?barn swallow?). the parasite was not found in nest boxes of tachycineta leucorrhoa vieillot (?white-rumped swallow?). caminicimex furnarii is recorded for first time parasitizing swallows and martins. interaction among these bird populations, associated with usurpation nests behavior, may explain the presence of the same cimicid species at the nests. according this idea, other possible c. furnarii hosts are suggested.

Abstract: Se examinaron nidos de cuatro especies de golondrinas que nidifican en la República Argentina, en búsqueda de Cimicidae. Caminicimex furnarii (Cordero & Vogelsang), chinche conocida como ectoparásita de Furnarius rufus (Gmelin) (Furnaridae) ( hornero ) y de Passer domesticus (L.) (Ploceidae) ( gorrión ), fue encontrada en nidos de tres especies de golondrinas: Progne chalybea (Gmelin) ( golondrina doméstica ), Progne elegans Baird ( golondrina negra ) e Hirundo rustica erythrogaster Boddaert ( golondrina tijerita ). El parásito no fue hallado en cajas-nido de Tachycineta leucorrhoa Vieillot ( golondrina de ceja blanca ). Nuestros resultados constituyen la primera cita de Caminicimex furnarii para golondrinas. La interacción poblacional entre estas aves, asociada al hábito de usar nidos ajenos, explicaría la presencia de la misma especie de chinche en sus nidos. En función de esta idea, se sugieren otros posibles huéspedes para C. furnarii. Nests of four species of Hirundinidae that nest in Argentina were prospected for Cimicidae. Caminicimex furnarii (Cordero & Vogelsang), a parasite of Furnarius rufus (Gmelin) (Furnaridae) ( oven bird ) and Passer domesticus (L.) (Ploceidae) ( house sparrow ) was found in nests of three species of Hirundinidae: Progne chalybea (Gmelin) ( gray-breasted martin ), Progne elegans Baird ( southern martin ) and Hirundo rustica erythrogaster Boddaert ( barn swallow ). The parasite was not found in nest boxes of Tachycineta leucorrhoa Vieillot ( white-rumped swallow ). Caminicimex furnarii is recorded for first time parasitizing swallows and martins. Interaction among these bird populations, associated with usurpation nests behavior, may explain the presence of the same cimicid species at the nests.

Abstract: the southern subspecies of the least seedsnipe (thinocorus rumicivorus rumicivorus) inhabits steppes, water meadows and lagoons, and in argentina it occurs in patagonia. during the winter it migrates to central chile and northeastern argentina and uruguay. farmers believe that these migrating birds feed on their winter crops and apply chemical control methods on them. since information on the biology of the least seedsnipe is scarce, we analyzed eight specimens captured in an oilseed rape (brassica napus) crop in chillar, buenos aires province, in july 2004. mean body weight of the specimens was 54.3 g. no significant morphometric differences were noted between sexes. mean stomach content weight was 0.42 g, and vegetal contents ranged between 11-67%. the remaining stomach contents were mineral fragments. in decreasing order of predominance, seeds of the following families were found: polygonaceae, poaceae, cyperaceae, fabaceae, convolvulaceae, chenopodiaceae, and asteraceae. no rests of oilseed rape were found in any of the analyzed stomach contents. we infer that least seedsnipe feeds mostly on vegetation growing as weeds in crops. being this species a target of chemical control by buenos aires farmers, we recommend that more thorough diet and foraging studies should be carried out.

Revista de la Sociedad Entomol?3gica Argentina , 2008,
Abstract: psitticimex uritui (lent & abalos), a typical bug parasite of "monk parakeets" myiopsitta monachus boddaert is recorded for the first time in nests of "brown cacholote" pseudoseisura lophotes (reichenbach) at entre ríos province. interaction among these bird populations, associated with nest adoption behavior by "monk parakeets", may explain the presence of the same cimicid species in both their nests. the low population of bugs in"brown cacholote" nests indicates that the "monk parakeets" are the original hosts.

Abstract: Estudios previos han demostrado que los aminobisfosfonatos, como el alendronato de sodio es un potente inhibidor de la reabsorción ósea, incrementa la densidad mineral del hueso y reducen los riesgos en fracturas de mujeres posmenopáusicas. El objetivo de este estudio fue desarrollar e investigar una nueva formulación en base a Alendronato, para ser colocada en forma subcutánea en el sitio quirúrgico. Materiales y métodos: La fórmula farmacéutica fue preparada con una dosificación de 0,5 mg/Kg de peso, se le adicionó buffer especiales, con un pH final de 5,5 en medios estériles. El control fueron buffers sin principios activos. El efecto de alendronato se evaluó en ratas machos Wistar (de 9 semanas de edad y un peso 176-214 g, n=8 por grupo), las cuales fueron divididas en dos grupos uno control y otro problema, La droga se inyectó en forma subcutánea en tiempos 0, 7, 14 y 30 días. Los animales fueron anestesiados con una solución de Ketamina/xilazina. Se realizó en la tibia incisiones las cuales no fueron rellenadas. Todos los animales fueron sacrificados por sobredosis con éter. Los parámetros estudiados fueron evaluación histopatológica observando infiltración de células inflamatorias (ICI), número y morfología de osteoclastos, lagunas de reabsorción (superficie del osteoclasto) y actividad osteoclástica. El análisis estadístico se realizó con el test chi cuadrado. Resultados: Los datos obtenidos no revelan diferencias estadísticamente significativas entre el grupo control y el grupo alendronato con respecto a (ICI), número de osteoclastos y actividad osteoblástica. En cuanto a la morfología de osteoclastos, lagunas de reabsoción (superficie del osteoclasto) y actividad osteoclástica, las diferencias estadísticas fueron significativas entre los dos grupos, favoreciendo al grupo que utilizó alendronato. Tejido oseo en remodelado, con trabéculas conteniendo osteoblastos con osteocitos viables e importante actividad osteoblastica y osteoplastica. En cuanto a la actividad de fosfatasa alcalina las diferencias estadísticas fueron notorias entre los grupos. Los valores inclusive fueron variando con los días de tratamiento deduciendo la actividad ósea con los sucesivos tratamientos. Tiempo 0: 480,00 UI/I Tiempo 7:500,00 UI/I Tiempo 15:652,00 UI/I Tiempo 30:824,00 UI/I Conclusiones: Estos estudios preliminares sugieren que el alendronato colocado en forma parenteral podría ser efectivo en la prevención de la pérdida ósea en las patologías óseas de la cavidad oral. Previous studies have shown that aminobisfosfonatos, such as alendronate sodium is a potent inhi
