Abstract:

Traumatic brain injury (TBI) is a worldwide public health problem. Populations with a growing number of vehicles are experiencing many traumas and accidents. The highest-risk group is young men. Significant advances in neurosurgery and intensive therapy have resulted in increased survival rates of TBI patients. These higher survival rates, in turn, have led to an increasingly higher number of patients with neurological, cognitive, clinical, and social problems. This lack of knowledge about TBI has been called by some “the silent epidemic”. In recent years, studies of patients with moderate and severe TBI are increasing. Glasgow Coma Scale ≤ 8 and abnormal pupils at admission are used to determine the prognosis of patients with moderate or severe TBI. Several biomarkers such as interleukins, thiobarbituric acid reactive species, and some hormones have been studied in an effort to aid prognosis. Testosterone plays a key role in men. Thus, an understanding of androgens in TBI is

Abstract: a crude formulation (vlaf) of an aqueous cold extract obtained from solanum lycocarpum necrotic tissue infected by crinipellis perniciosa was showed capable of reducing disease progress of tomato bacterial leaf spot, when previously sprayed on tomato plants. the fractions f0/30 and f30/60 were achieved by saline precipitation and they showed highest amounts of proteins from vlaf. the fractions were submitted to cationic exchange chromatography for protein scanning. non-retained peaks from this first chromatography were submitted to an anionic exchange chromatography. both retained and non-retained peaks from both ion exchanges were sampled and sprayed on cv. santa cruz kada tomatoes. contrasting peroxidase activities were observed 14 hours after sprayings. the samples that produced the highest peroxidase increases were the retained peak in cationic exchange from f0/30 (f0-30cmr) and the retained peak in anionic exchange chromatography from f30/60 (f30-60deaer). our results indicate the viability of searching for protein- or carbohydrate-derived molecules from vlaf aqueous extract.

Abstract: among the activities performed by the community health agent (cha), the educational actions are of fundamental importance for the provision of healthcare. therefore, the scope of this study was to evaluate these aspects in a random sample of 80 chas, drawn from 16 family health program units in piracicaba, s?o paulo state, representing 51.3% of the population studied. the data was collected through semi-structured interviews, which were recorded and transcribed, using a script with questions about dental health education practices conducted by the agents. for the data analysis, the answer processing technique of the collective subject discourse (csd) was used. it was established that dental health education activities are performed sporadically by chas and addressed mainly to pregnant women, mothers and children, in a vertical model of information transmission, seeking changes in individual behavior and the incorporation of healthy habits. the results suggest the need of chas to rethink the way they are developing their educational practices in dental health. however, for this to become a reality, it is indispensable to count on the support of the health manager in processes of permanent education directed to these professionals and to the whole team.

de Miranda Fábio,Vilar Jeane,Alves Ivana,Cavalcanti Sócrates
BMC Pharmacology , 2001, DOI: 10.1186/1471-2210-1-6
Abstract: Background Tabebuia avellanedae is a tree from the Bignoniaceae family. Commonly know as "pau d'arco" in Brazil, its inner bark is used as analgesic, anti-inflammatory, antineoplasic and diuretic at the Brazilian northeast. A validation of the plant usage has not been previously performed. Results Antinociceptive and antiedematogenic effects of Tabebuia avellanedae Lor. ex Griseb. inner bark were measured by nociceptive experimental models in mice. A rat paw edema test induced by carrageenan (1%) was also performed in rats to access the plant's antiedematogenic effect. The inner bark aqueous extract, administered via oral in three different concentration, namely 100, 200 and 400 mg/Kg, reduced the nociception produced by acetic acid (0.6% in water, i.p.) by 49.9%, 63.7% and 43.8%, respectively. The aqueous extract (200 and 400 mg/Kg, p.o.) reduced formalin (1%) effects only at the second phase of the experiment by 49.3% and 53.7%, respectively. Naloxone (5 mg/Kg, i.p.) was not able to revert the extract effect, however caffeine (10 mg/Kg, i.p.) reverted its effect by 19.8% at the second phase of the formalin test. The aqueous extract (200 mg/Kg, p.o.) inhibited edema by 12.9% when we used the rat paw edema model. The acute toxicity was low in mice. Conclusion The T. avellanedae inner bark aqueous extract presented antinociceptive and antiedematogenic activities at the used models, with a possible antinociceptive effect associated to the adenosine system.

Abstract: Objectives: to realize a literature systematic review on the incidence of cancer in the world. Methods: It was conducted a search in the database of the PUBMED with the descriptors epidemiology, prostate, cancer. We selected articles published from 2002 to 2007. It was used as a criterion for exclusion searches that are not directly addressing the incidence of prostate cancer in the population. It were collected the following variables: author(s), year, purpose, methodology and conclusions. Results: 10 articles were reported. Conclusions: It was possible to verify that in the world, the distribution of prostate cancer varies with ethnicity, genetic susceptibility and environmental factors such as diet. With regard to ethnicity, black men have greater susceptibility to tumor that white men of similar age. In the case of genetic, changes in alleles of genes that control the metabolism of androgens influence the incidence of tumor. As for nutrition, research confirms the influence of foods such as meat, fats and oils, ice cream, margarine and vegetable fat.
