Pollen hydration is usually tightly regulated and occurs in vivo only when desiccated pollen grains acquire water from the female, thus enabling pollen tube growth. Pollen tubes are easily visualized by staining with decolorized aniline blue, a stain specific for callose. We identified a mutant, raring-to-go, in which pollen grains stained for callose before anther dehiscence. When raring-to-go...

Standardized behavior raring scales and checklists offer unobtrusive evaluations of students' behavior in natural social environments. This study investigated the interrater agreement of the Adjustment Scales for Chil~ dren and Adolescents (ASCA), a behavior rating scale used in school settings. Participants were 71 students enrolled in a variety of special programs who were rated by 29 observe...

This study aimed to investigate whether sense of coherence (SOC) and lack of control are related to outcome after moderate orthopaedic injuries. One hundred and eleven patients with orthopaedic injuries were included. The patients were followed up 1 year after the injury (physical examination, Disability Raring Index (DRI), Visual Analogue Scale, Beck's Depression Inventory and SF-36). At a min...

Farming of the freshwater fish is emerging in Brazil and many species from the wild are promising. The teleost matrinxã (Brycon cephalus) holds several characteristics such as fast growth rate, high commercial value and adaptability to artificial raring conditions, which make it a promising species for commerce. The use of pesticides in aquatic environment is frequent in Brazil, and methyl para...

Resurgence of public interest in the ethnomedical practices in both the developing and developed countries is increasing. As a result, the trade of herbal products in the national and international market is also growing. The rich biodiversity and associated knowledge system particularly in Asia are well known. Over 8,000 wild plant species with about 1,75,000 specific preparations are known to...
