Avaliação do potencial citotóxico, moluscicida e alelopático dos extratos hidroetanólicos das folhas de Stryphnodendron obovatum Benth

Stryphnodendron obovatum Benth. known as barbatimão de folha miúda, is a typical tree of the Midwest and Southeast “Cerrado” regions of Brazil. Several secondary metabolites have been identified in its barks, including tannins, described on the literature as allelochemicals. Beholding to identify a possible allelopathic activity in S. obovatum leaves, we tested hydroethanolic EtOH:H2 O (70% and 50% v/v) extracts, in different concentrations, on the initial development of cucumber (Cucumis sativus L.). Among the results, we highlight the effect of the 50% hydroethanolic extract in inhibiting the formation of the main and the secondary roots and the stimulation of the hypocotyl growth in C. sativus by the 70% hydroethanolic extract, both in all concentrations tested. The cytotoxic activity, evaluated by bioassay toxicity on Artemia salina Leach., was negative for the tested extracts (LC50> 1000 mg.mL-1). Concomitantly, the molluscicidal activity, evaluated against snails of Biomphalaria glabrata Say, presented low acute toxicity of solutions of 70% hydroethanolic extract at concentrations of 128.9 mg.mL-1 and 172.8 mg.mL-1 and values above 250 mg.mL-1 to solutions of 50% hydroalcoholic extract, being therefore considered inactive for these. The results suggest the existence of allelochemicals in the extracts tested and they have low toxicity.

Subconjunctival and topical application of recombinant tissue plasminogen activator in rabbits

To quantify fibrin degradation products after topical and subconjunctival administration of recombinant tissue plasminogen activator in rabbits. Methods: Fibrin formation was induced in the anterior chamber in 25 rabbits. Subsequently, five rabbits received an injection of r-TPA (positive control) in the anterior chamber, another 10 received a subconjunctival injection of r-TPA, and the remaining 10 received instillations of topical r-TPA. Afterwards, samples of aqueous humor were collected and semi-quantitative analysis of fibrin degradation products (FDP) was performed. Results: No statistical differences were noted between the treatment and control groups at any time point. Fibrin degradation products semi-quantification showed statistical improvement in the control group and the subconjunctival group. Conclusion: Fibrin degradation products were observed in the anterior chamber after subconjunctival administration of r-TPA. However, it was probably not sufficient to cause fibrin degradation. Topical r-TPA did not effectively absorb anterior chamber fibrin.

Avaliação ultrassonográfica de crianças com hipotireoidismo congênito

To establish benchmarks and study some sonographic characteristics of the thyroid gland in a group of euthyroid children aged up to 5 years as compared with age-matched children with congenital hypothyroidism. Thirty-six children (17 female and 19 male) aged between 2 months and 5 years were divided into two groups - 23 euthyroid children and 13 children with congenital hypothyroidism - and were called to undergo ultrasonography. In the group of euthyroid children (n = 23), mean total volume of the thyroid gland was 1.12 mL (minimum, 0.39 mL; maximum, 2.72 mL); a homogeneous gland was found in 17 children (73.91%) and 6 children (26.08%) had a heterogeneous gland. In the group of children with congenital hypothyroidism (n = 13), mean total volume of the thyroid gland was 2.73 mL (minimum, 0.20 mL; maximum, 11.00 mL). As regards thyroid location, 3 patients (23.07%) had ectopic thyroid, and 10 (69.23%) had topic thyroid, and out of the latter, 5 had a homogeneous gland (50%) and 5, a heterogeneous gland (50%). In the group with congenital hypothyroidism, 6 (46.15%) children had etiological diagnosis of dyshormoniogenesis, 3 (23.07%), of ectopic thyroid, and 4 (30.76%), of thyroid hypoplasia. Thyroid ultrasonography is a noninvasive imaging method, widely available, easy to perform and for these reasons could, and should, be performed at any time, including at birth, with no preparation or treatment discontinuation, to aid in the early etiological definition of congenital hypothyroidism.

Case report: Cornelia de Lange Syndrome (CDLS)

The Cornélia of Lange´s syndrome is a genetic anomaly, described and published by Cornelia Catharina of Lange in 1933, however, their aspects were described previously by Winfried Robert Clemens Brechmann in 1916, that’s why it is also known as Brachmann of Lange’s syndrome. The most frequent clinical characteristics include typical face dismorfia, variable degree of mental delay, anomalies of the hands and feet, multiple malformations, retardation of the pre and postnatal physical development and microcephaly variable intellectual compromising. Some facial characteristics are peculiar and they are mixed with the inherited lines of their own family, the united brows, the long lashes, the small nose, the round face, the fine lips and lightly inverted. As oral manifestations they present micrognathia, dental crowding, periodontal disease, delayed dental eruption, enamel hypoplasia, erosion of the enamel and dentine caused by stomach acids of the gastroesophageal reflux and atresia of the dental arches. The purpose of this paper is to present a clinical report of a boy bearer of this syndrome assisted at CAOE - FOA - UNESP, emphasizing the importance of multiprofessional team for the diagnosis and treatment of this syndrome.

Apresentação de métodos para implementação de plataformas colaborativas de Sistemas Automatizados de Produção

Automated Production Systems Development involves aspects concerning the integration of technological components that exist on the market, such as: Programmable Logic Controllers (PLC), robot manipulators, various sensors and actuators, image processing systems, communication networks and collaborative supervisory systems; all integrated into a single application. This paper proposes an automated platform for experimentation, implemented through typical architecture for Automated Production Systems, which integrates the technological components described above, in order to allow researchers and students to carry out practical laboratory activities. These activities will complement the theoretical knowledge acquired by the students in the classroom, thus improving their training and professional skills. A platform designed using this generic structure will allow users to work within an educational environment that reflects most aspects found in Industrial Automated Manufacturing Systems, such as technology integration, communication networks, process control and production management. In addition, this platform offers the possibility complete automated process of control and supervision via remote connection through the internet (WebLab), enabling knowledge sharing between different teaching and research groups.
