Diagnóstico pré-natal de aneurisma e divertículo do ventrículo esquerdo

Descrevemos dois casos de protrusão localizada do ventrículo esquerdo (VE), entidade que tem sido descrita na literatura como aneurisma ou divertículo. Em ambos os casos, observou-se uma evolução distinta da anteriormente relatada. A incidência e história natural dessas raras anomalias são pouco conhecidas, podendo evoluir de forma assintomática ou gerar graves complicações e até o óbito no período pré-natal. A abordagem terapêutica deve ser individualizada.

Influência de diferentes cavalos e da época de colheita no teor de vitamina C na laranja natal

This paper deals with the variation of the ascorbic acid content in Natal orange as related to the type of rootstock and to the picking time. The determinations were carried out in the juice of fruits which had practically the same ratio total solids/acidity being selected only the highest values of such quotient. The results can be summaryzed as follows: 1. The rootstock has a significant influence on the vitamin C content of the scion; this influence shows two interesting aspects: first, the ascorbic acid contet itself varies as a function of the rootstock; among the three rootstocks studied the highest values were obtained on scion growing on Serra d'água orange; the lowest values were found in "limão rugoso" and "limão francês" was intermediate; the second point to be emphasyzed is the manner of variation of the ascorbic acid content in the different rootstocks: in the case of Serra d'água. the content decreases slowly whereas in "limão francês" the level remains nearly constant and suddenly falls down; finally in the case of "limão rugoso" the amount of ascorbic acid increases significantly to return to the primitive level. 2. The amount of ascorbic acid, not considering the rootstock influence, varies strongly as a function of harvesting time; for this reason the present factor must be borne in mind when sampling for the determination of ascorbic acid in orange is concerned.

Macrocheles muscaedomesticae (Acari, Macrochelidae) and a species of Uroseius (Acari, Polyaspididae) phoretic on Musca domestica (Diptera, Muscidae): effects on dispersal and colonization of poultry manure

Differences in the phoresy of the mites Macrocheles muscaedomesticae (Scopoli, 1972) (Macrochelidae) and Uroseius sp. (Polyaspidae) on the house fly, Musca domestica (Linnaeus, 1758) and the similarities in their phoretic dispersal and parasitism are discussed, altogether with the effects on predator-prey interactions. The prevalence and intensity of phoresy in the mite species were significantly related to the attachment site on the hosts. The phoresy of Uroseius sp. was correlated with temperature but not with rainfall and relative humidity. Selective pressure in the environment resulted in displacement and the emergence of local and regional populations. These results suggest that in each habitat the populations will use different resources and will show several relationships with other species, as well as a selection for morphological and behavioral types.
