In this paper, we present a new construction and decoding of BCH codes over certain rings. Thus, for a nonnegative integer t, let A0 ⊂ A1 ⊂···⊂ At−1 ⊂ At be a chain of unitary commutative rings, where each Ai is constructed by the direct product of appropriate Galois rings, and its projection to the fields is K0 ⊂ K1 ⊂···⊂ Kt−1 ⊂ Kt (another chain of unitary commutative rings), where each Ki is made by the direct product of corresponding residue fields of given Galois rings. Also, A∗ i and K∗ i are the groups of units of Ai and Ki, respectively. This correspondence presents a construction technique of generator polynomials of the sequence of Bose, Chaudhuri, and Hocquenghem (BCH) codes possessing entries from A∗ i and K∗ i for each i, where 0 ≤ i ≤ t. By the construction of BCH codes, we are confined to get the best code rate and error correction capability; however, the proposed contribution offers a choice to opt a worthy BCH code concerning code rate and error correction capability. In the second phase, we extend the modified Berlekamp-Massey algorithm for the above chains of unitary commutative local rings in such a way that the error will be corrected of the sequences of codewords from the sequences of BCH codes at once. This process is not much different than the original one, but it deals a sequence of codewords from the sequence of codes over the chain of Galois rings.

In the present immunohistochemical study, the expression of vascular endothelial growth factor, nitric oxide synthase 1 and 3, and Ki-67 in the gingival tissues of renal transplant patients treated with cyclosporin A was assessed. Gingival overgrowth (GO) frequently occurs in transplant patients receiving immunosuppressive drugs such as cyclosporine and this gingival inflammation might play an important role in the pathogenesis of drug-induced GO. Twenty-eight human gingival biopsies were taken from healthy patients with chronic periodontitis (N.=14 control group), and from renal transplant recipients treated with cyclosporin A (N.=14 test group). The retrieved specimens were immunohistochemically processed and stained for vascular endothelial growth factor, nitric oxide synthase 1 and 3, and Ki-67. The levels of vascular endothelial growth factor, nitric oxide synthase 1 and 3, and Ki-67 were found to be significantly different among groups (P>0.001), with patients treated with cyclosporin A showing higher levels of all the analyzed markers compared to control group. In summary, the data from this pilot study suggests that the investigated factors have a role in the inflammation processes associated to immunosuppressive therapy. However, further studies with a larger sample population need to be conducted for an exhaustive knowledge of the mechanisms leading to GO.

This research analyzes the discourse of teachers of ancient oriental arts, namely: Yoga, Tai Chi Chuan, Kung Fu, Lian Gong, Qwan Ki Do, reveals the meaning that subjects have about what are the benefits to health of those already considered practical alternatives conventional treatment of health. The research uses the phenomenological method specifically the method of the phenomenon. The method first provides a pre-reflection on the oriental arts, exposing not systematically, some curiosities changing between aspects of oriental arts: historical, main teaching methods, styles, the character of struggle, why are linked to health, the benefits of their practices, movements, philosophy, concepts, ways of acting, the roots, the basics. In this article the pre-reflection does not appear to meet the standards of Congress page limit. Rather concentrate on the next step of the research and present the phenomenon situated in the experience of those who have experienced it in the case of the five arts teachers mentioned above. The method performs individual analysis or ideographic analysis of the five discourses of teachers from each oriental art and then conducts the general or nomothetic. The result is presented an analysis of generalities, convergence, divergence and individuality of meanings expressed by the subject, to finally develop a discussion of these data and weave a synthesis. The analyzes reveal that Eastern practices currently as some of these five analyzed here, those involving aspects of struggle and concentration are excellent allied health development and well-being. Understanding the philosophical aspect is inherent in the practice of the movements, although the character of the struggle, which they transmit through knowledge of their origins and roots is the current thinking routine that generates a life philosophy of selfhelp, self-enabling and tranquility preparation to overcome the tensions, disputes, everyday challenges. The speeches also reveal that the psychophysical aspects of diseases are real, because the practices of movements and the physical drilling of these oriental arts have enabled visible improvements in health by working the mental and the physical in an integrated manner. Masters must have all the knowledge to better meet today's society, preserving these cultures, passing them through the generations.

Objectives: To evaluate the Bcl-2, Bax, Bad and Bak immunoexpression in tumor and nontumorous tissue of 130 patients with colorectal carcinoma submitted to surgery at São Paulo Hospital, EPM/ UNIFESP, from 2002 to 2005, and to correlate the immunoexpression data with the apoptotic index (AI, obtained by anti-cleaved caspase 3 and M30 labeling), cell proliferation score (CPS, obtained by Ki-67), immunoexpression of p53 and patient’s clinical prognosis. Results: Positive correlation was verified between Bcl-2 protein family in tumor and nontumor tissue. Only Bcl-2 protein correlated with IA and CPS in the tumor. Positive correlation was observed between pro- -apoptotic proteins and Bcl-2 protein. In the adjacent mucosa, Bcl-2 correlated with Ki-67 and p53, but not with IA. Carcinomas exhibited higher immunoexpression of CPS and IA markers. No correlation occurred between immunoexpression data and patient survival. Conclusion: Positive correlation was observed between the pro-apoptotic proteins of the Bcl-2 family and the anti-apoptotic protein Bcl-2. In the adjacent nontumor mucosa, Bcl-2 correlated with Ki-67 and p53, but not with AI. Carcinomas presented greater immunoexpression for CPS and AI markers; however immunoexpression of these markers was not correlated with patient survival.

Primary malignant epithelioid hemangioendothelioma (MEH) of the thyroid is a rare neoplasia with only a few cases reported in the literature. We report a 75 year old man, who presented with a substernal goiter and compressive symptoms. Ultrasonographic evaluation revealed a hypoechogenic nodule in the left lobe, measuring 4.1 cm in maximum diameter, and associated gross calcifications. Fine needle aspiration yielded hemorrhagic material. A left thyroid lobectomy and isthmusectomy was performed. The surgical specimen contained a malignant epithelioid hemangioendothelioma measuring 6 x 4 x 3 cm that had infiltrated about 50% of the thyroidal parenchyma, and surrounded a necrotic nodule. Immunohistochemistry results corroborated the histopathological findings; staining was positive for AE1/AE3, CD31, CD34, factor VIII-related antigen, and Ki-67 expression. Because of the patient’s comorbidities, surgical complementation was not undertaken and he has been undergoing conservative treatment.
