Male, female, pupa, larva and egg of a new genus and species of Gracillariidae (Gracillariinae), Spinivalva gaucha Moreira and Vargas from southern Brazil are described and illustrated with the aid of optical and scanning electron microscopy. A preliminary analysis of mitochondrial DNA sequences including members of related lineages is also provided. The immature stages are associated with Pass...

Çalışmada, ülkemiz piyasasına son yıllarda meyveleriyle de giren, park ve bahçe kenarlarında sarılıcı tırmanıcı bitki olarak yetiştirilen tıbbi değeri olan, Passifloraceae familyasında yer alan, ekonomik değere sahip Passiflora incarnata, P. alata, edulis cearulea türlerinin geleneksel kullanılışı, kimyasal bileşimi biyolojik etkilerinin yapılan çalışmaları derlenmiştir. Çalışmanın deneysel kıs...

One of the long-standing paradoxes in genomic evolution is the observation that much of the genome is composed of repetitive DNA which has been typically regarded as superfluous to the function of the genome in generating phenotypes. In this work, we used comparative phylogenetic approaches to investigate if the variations in genome sizes (GS) should be considered as adaptive or neutral process...

An increased yield of the crude material with antibacterial and antifungal activity produced by Passiflora species was obtained by aerated bathing of cut rinds of banana passion fruit in water in rotating cylindrical bottles. The crude material was separated into several fractions by thin-layer chromatography with the use of silica gel and ethyl acetate-chloroform (2: 1). The fractions showing ...

Calluna vulgaris, Molinia caerulea and Pteridium aquilinum are three forest understorey species that compete with tree seedlings for environmental resources. Forest managers therefore seek to control their growth, which is driven in part by the light available in the forest understorey. An experiment was set up in a nursery in which the three understorey species C. vulgaris, M. caerulea and P. ...

In a prospective study, nine patients with phlegmasia caerulea dolens (PCD) related to iliac occlusive thrombosis were treated with intravenous thrombolysis. After thrombolysis, despite no significant improvement in the Marder score value, progression to venous gangrene, major hemorrhage or death was not observed and no amputation was needed. Intravenous thrombolysis should be seriously conside...

The genetic diversity and characteristics of commercial interest of Passiflora species make it useful to characterize wild germplasm, because of their potential use for fruit, ornamental and medicinal purposes. We evaluated genetic diversity, using RAPD markers, of 32 genotypes of Passiflora cincinnata collected from the wild in the region of Vitória da Conquista, Bahia, Brazil. Thirteen primer...

A differentiated structure called "aril" has been described in seeds of several plant species during the course of evolution and might be considered as a supernumerary integument. Besides its ecological function in seed dispersal, the structure also represents a relevant character for systematic classification and exhibits important properties that impart agronomic value in certain species. Lit...
