Caracterização morfológica das sementes e plântulas de seis espécies invasoras do gênero Solanum L

Morphological caracterization of the seeds and seedlings of six weed especies of the genus Solanum L. The seeds of the genus Solanum are very similar, however, the association of their external characteristics with the anatomical features, such as hilum shape, the texture and the type of the seed coat sculptures, as well as the curved (circulated or coiled) shape of the embryo, are parameters of great importance in the taxonomical identification at the species level. It is are presented the morphological descriptions of the genus Solanum and a more detailed description of each studied species in terms of seed and seedling structures, including illustrations and taxonomical keys for the identification of Solanum aculeatissimum Jacq., S. americanum Mill., S. ciliatum Lam., S. sisymbriifolium Lam., S. sordidum Sendt. e S. viarum Dunal. There are also indications of the common names, the type of reproduction and dispersion, the crops in which the species is considered as a weed and the agricultural seeds in which it is found as a weed seed.

Espécies reativas de oxigênio e de nitrogênio, antioxidantes e marcadores de dano oxidativo em sangue humano: principais métodos analíticos para sua determinação

We review here the chemistry of reactive oxygen and nitrogen species, their biological sources and targets; particularly, biomolecules implicated in the redox balance of the human blood, and appraise the analytical methods available for their detection and quantification. Those biomolecules are represented by the enzymatic antioxidant defense machinery, whereas coadjutant reducing protection is provided by several low molecular weight molecules. Biomolecules can be injured by RONS yielding a large repertoire of oxidized products, some of which can be taken as biomarkers of oxidative damage. Their reliable determination is of utmost interest for their potentiality in diagnosis, prevention and treatment of maladies.

Número cromossômico em espécies brasileiras de Adesmia DC. (Leguminosae-Faboideae)

Chromosome numbers of 11 South-Brazilian species of Adesmia were determined. The cytological preparations were obtained by squashing cells of root tips, using the acetic-orcein method. The chromosome number for all the species studied was 2n=20, excepting A. incana var. incana with 2n=ca.40. The counts are new for nine species, and the other two agree with the literature. It is suggested x=10 as the basic number for the genus. Up to the present only four species were cited as polyploid.

Notas sobre duas espécies de Thelypteris Schmidel (Thelypteridaceae - Pterophyta) do Brasil

During the taxonomic study of the Thelypteridaceae from southeastern Brazil was founded Thelypteris polypodioides (Raddi) C. F. Reed and Thelypteris villosa (Link) C. F. Reed, two rare and poorly known species. The taxonomic position of these species is uncertain. This study presents key, descriptions, illustrations, data on geographical distribution, and comments for both species, as well as comments on taxonomic affinity between the two species and Thelypteris subgenera.

Números cromossômicos em espécies de Acosmium Schott e Leptolobium Vogel (Leguminosae, Papilionoideae)

A cytotaxonomic analysis of species of Acosmium Schott e Leptolobium Vogel was carried out, by determining their chromosome numbers. The three species of Acosmium and five species of Leptolobium (representing 50% of the genus) were studied from seeds obtained from different regions of Brazil. Chromosome counts were new for all Acosmium species and for four Leptolobium species. For Acosmium cardenasii, 2n = 18 was constantly observed, while occurring at the same meristem were found 2n = 18, 24 e 32 in A. diffusissimum and 2n = 18 e 32 in A. lentiscifolium. For Leptolobium, all studied species had 2n = 18, confirming a previous count for L. dasycarpum. The results showed that chromosome numbers of Acosmium and Leptolobium species are homogeneous, confirming the basic number x = 9 for both genera. Therefore, chromosome numbers do not provide a useful taxonomic character distinguishing Acosmium from Leptolobium.

EFEITO DA ASSOCIAÇÃO DE PECTINASE, INVERTASE E GLICOSE ISOMERASE NA QUALIDADE DO SUCO DE BANANA

The association of 0,03 % v/w pectinase (Clarex), 0,6 % v/w invertase (Invertase-S) and 0,5 % w/w glucose isomerase (Taka-sweet) in industrialized banana (Musa cavendishii) pulp, under conditions of hydrolysis 40oC, 15 minutes, was observed and compared to other three enzymatic treatements: 0,03 % v/w pectinase (Clarex); 0,03 % v/w pectinase (Clarex) associated to 0,6 % v/w invertase (Invertase-S); and 0,03 % v/w pectinase (Sigma) associated to 0,03 % cellulase (Sigma) to determine the quality using a group of physical, physico-chemical, chemical, microbiological and sensory properties of the banana juices obtained. These properties had not differ significantly in function of pectinases and celulase employed. The addition of invertase had increased sweetness and decreased viscosity in juice. On the other side, the addition of glucose isomerase in inverted juice was not able in increasing significantly fructose content.

Coma mixedematoso em paciente com neurofibromatose tipo 1: associação rara

Myxedema coma, a rare but fatal emergency, is an extreme expression of hypothyroidism. We describe a 51-year-old male patient who has discontinued hypothyroidism treatment 10 months earlier and developed lethargy, edema, and cold intolerance symptoms. He also had a previous diagnosis of neurofibromatosis. After admission, he progressed to respiratory insufficiency and coma. The prompt recognition of the condition, thyroid hormone replacement, and management of the complications (hypoventilation, cardiogenic shock associated with swinging heart, adrenal and renal insufficiency and sepsis), resulted in a favorable evolution.
