1. Post pollination events in a self-sterile hexaploid monoembryonic lineage of Handroanthus serratifolius (Vahl) S. Grose (Bignoniaceae)
ABSTRACT In diploid late-acting self-incompatible (LSI) species of Bignoniaceae, self-pollinated pistils show a marked delay in ovule penetration by pollen tubes, followed by delayed, but otherwise normal, initial stages of endosperm development and subsequent pistil abscission. Most polyploid species of Bignoniaceae are apomictic and set selfed fruits with

2. CRESCIMENTO E ANÁLISE NUTRICIONAL DE ESPÉCIES ARBÓREAS EM SUBSTRATO CONTAMINADO POR HERBICIDAS LIXIVIÁVEIS
RESUMO A contaminação de ecossistemas por resíduos de defensivos agrícolas, especial atenção deve ser dada para os herbicidas passíveis de lixiviação. O objetivo foi selecionar espécies arbóreas para a rizodegradação de ambientes contaminados por resíduos de 2,4-D e atrazine, e para recomposição de mata ciliar aos campos agrícolas e, consequ

3. Self-sterility in the hexaploid Handroanthus serratifolius (Bignoniaceae), the national flower of Brazil
Polyploidization is common among angiosperms and might induce typically allogamous plants to become autogamous (self-compatible, relying on sexual self-fertilization) or apomictic (achieving asexual reproduction through seeds). This work aimed to determine whether neopolyploidy leads to the breakdown of the self-incompatibility system in the hexaploid non-ap

4. Diversidade e abundância sazonal da avifauna em duas planícies de maré no estuário da baía da Babitonga, norte de Santa Catarina
Informações sobre a ocorrência de aves nos ambientes estuarinos de Santa Catarina ainda são escassas. O objetivo deste trabalho foi registrar a diversidade, abundância e variação sazonal das aves em duas planícies de maré na baía da Babitonga. As amostragens foram realizadas durante um ano (maio de 2006 a abril 2007). No total foram identificadas 2

6. Common ground in the transcriptional profiles of wounds and tumors
Recent microarray studies comparing wounds and tumors have identified characteristic similarities in gene expression that may prove to be useful for assessing cancer prognosis and for choosing subsequent treatment.

7. Immunization of inbred guinea pigs with varicella-zoster virus grown in a syngeneic transformed embryo cell line.
Varicella-zoster virus was serially propagated in a chemically transformed and cloned line of embryo cells (designated "104 C1") derived from the inbred strain 2 guinea pig. When strain 2 guinea pigs were immunized with varicella-zoster virus subcultivated in the syngeneic cell line, they produced high-titer virus-specific antiserum which lacked antibody aga

8. A role for endogenous glucocorticoids in wound repair
Exogenous glucocorticoids are known to inhibit wound repair, but the roles and mechanisms of action of endogenous glucocorticoids during the healing process are as yet unknown. Therefore, we wounded mice expressing a DNA-binding-defective mutant version of the glucocorticoid receptor (GRdim mice) and also analysed fibroblasts from these animals in vitro. We

9. Clinical Pharmacology of Intravenously Administered Trimethoprim-Sulfamethoxazole
Pharmacokinetic studies of intravenously administered trimethoprim-sulfamethoxazole (TMP-SMX) were conducted in 11 patients with cancer while they received therapy with this drug combination for infection. Each patient received 160 mg of TMP and 800 mg of SMX every 8 h. The highest plasma concentrations of both agents were attained at the end of a 1-h infusi

10. Varicella-zoster virus: isolation and propagation in human melanoma cells at 36 and 32 degrees C.
Cell lines derived from human malignant melanoma tumors are susceptible to infection with varicella-zoster virus (VZV). Within 5 days after inoculation of vesicular fluid, cytopathic changes appeared in melanoma cell monolayer cultures that were incubated at either 36 or 32 degrees C. The VZV isolates at the two temperatures were serially propagated by passa

11. Monoclonal antibodies against three major glycoproteins of varicella-zoster virus.
Varicella-zoster virus (VZV) codes for three prominent glycoproteins--gp62, gp98, and gp118--in infected cell cultures. To characterize individually these known immunogens, we first inoculated BALB/c mice with crude VZV extracts, produced hybridoma cultures by Köhler-Milstein cell-fusion technology, and screened culture supernatants by indirect immunofluore

12. Immunogenic glycoproteins of laboratory and vaccine strains of Varicella-Zoster virus.
High-titered antisera were prepared in guinea pigs and rabbits against two strains of varicella-zoster virus (VZV): VZV-32, a low-passage laboratory strain, and VZV-Oka, a vaccine strain attenuated by passage in both human and guinea pig embryo cells. When the animal VZV-immune sera, as well as a human zoster serum, were used to precipitate radiolabeled glyc
