Estimativa de la edad y peso a la primera monta de novillas en el Pantanal brasileño

Esto trabajo tuvo como objetivo estimar la edad y peso a la primera monta de novillas de las razas Nelore (N), Pantaneira (P) y Mestizas Pantaneira x Nelore (PxN). Se utilizó un total de 98 hembras, siendo 51, 24 y 23 pertenecientes a las razas N, P y PxN, respectivamente. El análisis estadístico de los datos no reveló diferencia significativa (P = 0,3595) para el peso a la primera monta entre las razas estudiadas. El análisis de varianza no reveló diferencia significativa (P = 0,307) entre las edades a la primera monta entre razas, mostrando 3,5, 3,4 y 3,2 años para las novillas P, N y ½PxN, respectivamente.

Farmacología en la tercera edad: Medicamentos de uso continuo y peligros de la interacción medicamentosa

Introduction: It was observed a considerable growth of elderly people. They are who use more medicines. The physiological changes associated with the age advancing can make pharmacokinetic and pharmacodynamic alterations. The cognitive decline, physical limitations and associate chronic pathology affect the medications appropriately use ability. Aims: Based in a literature review, appoint the main pharmacological groups prescribed to the elderly and the drug-drug interaction risks. Conclusion: The most of elderly use continually at least 3 medicines, the most prescribed are to cardiovascular and psychic diseases treatment.

Population trends of the red palm mite, raoiella indica hirst (acari: tenuipalpidae) and associated entomopathogenic fungi in trinidad, antigua, st kitts and nevis and dominica

A survey to determine population trends and entomopathogenic fungi associated with the red palm mite (RPM), Raoiella indica, was conducted in Trinidad, Antigua, St. Kitts and Nevis and Dominica. RPM population density was evaluated by sampling a total of ten coconut palms per site in Antigua, St. Kitts and Nevis, Dominica, and Trinidad (Manzanilla and Icacos). Mites from the four islands were either surface sterilized or left unsterilized before being cultured on Tap Water Agar (TWA). A total of 318 fungal colonies were retrieved. A further 96 mites from Dominica were kept on sterile moist filter paper in a humidity chamber and a further 85 colonies were isolated. Based on morphological observations of all 403 isolates, a sample consisting of 32 colonies (8 %) was sent for identification at CABI-UK. Of the 27 fungi positively identified, 15 isolates belonged to the genera Cladosporium, three to Simplicillium spp., and one to Penicillium. Other fungi genera with limited or no entomopathogenic potential included: Aspergillus, Cochliobolus, Fusarium, Pestalotiopsis and Pithomyces. The results show a potential use of entomopathogenic fungi for population management of the red palm mite in the Caribbean region.
