Opossum is considered one of the most primitive mammals, with transition evolutive characteristics. In mammals, the aorta artery is referred as the main body blood vessel. The arteries wall structural organization follows a basic pattern, being contituted of three tunics: Intima, Median and Adventicial. After euthanasia, three samples of opossum had segments from the aorta artery ascendent, thoracic descending and abdominal descending portions removed, fixed in phormalin at 10% for 48 hours. Then, the material was washed in alcohol 70% several times, dehydrated in alcohois of growing concentrations, diafanized in xylol and included in "paraplast". Cuts with 5 to 7 mu m of thickness were placed in histological laminae and submitted to color methods of Hematoxilin-Eosin, Masson, Mallory and Calleja Tricromics. It was observed that in the different portions ascendent, thoracic and abdominal descending of aorta, the intima tunic presents much thick, made up of a layer of smooth muscular cells and elastic fibers, forming a limiting internal elastic membrane. In the three portions studied, the median tunic was the most evident layer, constituted of colagen fibers, smooth muscular cells arranged in a circular manner and elastic fibers, showing a variation in the mural elements proportion. It was evidenced the presence of a external elastic lamina, marking the transition between the median and adventicial tunic, formed by elastic fibers condensation. The aortic adventicial tunic showed to be little organized, having in its structure predominantely colagen fibers beans with some isolated smooth muscular fibers or in small fascicules among a few elastic fibers.

Avaliaram-se as alterações do proteinograma sérico de eqüinos submetidos à isquemia e reperfusão do cólon menor por distensão intraluminal. Foram utilizados 10 animais submetidos à laparotomia pelo flanco, em posição quadrupedal, para a indução de obstrução no cólon menor durante um período de quatro horas. Cinco animais foram instrumentados, mas sem distensão (grupo controle - G1). em cinco outros animais, foi realizada isquemia mural por distensão do cólon menor via manguito inflado com 40mmHg (grupo distendido - G2). Foram colhidas amostras de sangue antes da intervenção cirúrgica (M1), com 4 horas da colocação do manguito (M2) e com 3 horas (M3) e 12 horas (M4) de reperfusão. Após centrifugação e fracionamento das amostras, as proteínas de fase aguda foram separadas por eletroforese em gel de poliacrilamida contendo SDS-PAGE, e suas concentrações determinadas por densitometria computadorizada. Foram encontradas 19 proteínas no fracionamento eletroforético, com peso molecular variando de 185.000 a 14.000 Daltons (Da). Os pesos moleculares encontrados, correspondentes às proteínas mais conhecidas, foram ceruloplasmina, 130.000 Da; proteína C-reativa, 122.000 Da; transferrina, 85.000 Da; α1-antitripsina, 61.000 Da; haptoglobina, 47.000 Da; e glicoproteína ácida, 40.000 Da. Os resultados mostram que proteínas de fase aguda se alteram após o trauma cirúrgico.

A interação entre arte e ciência foi intensa durante o Renascimento, sofrendo declínio nos anos posteriores com retomada significativa no século XX, principalmente com o uso de técnicas de identificação, datação de obras de arte e o desenvolvimento de novos materiais. O relacionamento entre artes plásticas e Cirurgia da Mão mantêm-se intenso , sendo freqüente o uso de reproduções artísticas da mão nas ilustrações de textos científicos. Objetivando compreender o papel da mão nas artes plásticas, reproduções de obras de artes (esculturas e pinturas) representativas de vários estilos ou períodos da história da arte foram analisadas com enfoque no estudo das mãos. Detalhes anatômicos, relacionamento com outras estruturas do corpo humano, papel na composição e aspectos simbólicos das mãos foram estudados no contexto histórico e artístico de obras de arte do período paleolítico (pré-história) até o século XX. A representação da mão nas artes plásticas está diretamente relacionada ao estilo ou período da obra e à capacidade individual de interpretação e execução do artista.

Ameloblastoma is a true neoplasm of odontogenic epithelial origin. It is a slow-growing benign tumor of the jaw, and patients usually present late after the tumor achieves considerable size to cause facial disfigurement. Diagnosis mainly from tissue biopsy and radiograph findings does assist in differentiating between types of ameloblastoma. Unicystic ameloblastoma is a tumor with a strong propensity for recurrence. There is a difference in biological behavior between mural unicystic ameloblastoma and those which are simply cystic or show intraluminal proliferation. The challenges in the management of this tumor are to provide complete excision in addition to reconstructing the bony defect, to provide the patient with reasonable cosmetic and functional outcome. The authors report a case of a mural unicystic ameloblastoma in a 23-year-old man who was treated by partial resection of the mandible. Biomedical prototypes were used because they provide acceptable precision and are useful for treatment planning.

Dance is regarded as one of the oldest art forms, which is based on evidence from prehistoric paintings found in caves; man expressed himself through body language prior to the development of spoken and written forms of communication. Dance was then used during important events, common to their era and culture, and often in religious rituals, to ensure good harvests - their economic activity. Belly-dance appeared approximately eight thousand years B. C. E. as a sacred dance firstly practiced by priestesses, and after that, it was popularized amongst women from Mesopotamia. Virtually considered an ancient form of physical exercise, it is still practiced by Bedouin women as a preparation for spontaneous delivery. In Brazil, belly-dance is widely practiced and our corporal culture enables its learning and improvement, resulting in professional dancers.

Este artigo objetiva apresentar, de forma introdutória, a possibilidade e a necessidade de diálogo entre a linguagem pictórica e o discurso científico da Geografia. Para tal, apresenta alguns elementos do alfabeto das pinturas de imagens a partir tanto da semiótica quanto da gestalt, analisadas por Fayga Ostrower e Donis Dondis. O exercício interpretativo dá-se a partir do conceito de paisagem aplicado sobre as imagens elaboradas artisticamente por grandes pintores da humanidade, contextualizando-as a partir dos elementos técnicos e tecnológicos que existiam na época e no lugar, e da forma como esses interferem nos processos de elaboração e interpretação das obras. Para exemplificar isso, utilizam-se três pinturas elaboradas em diferentes períodos, a partir da Europa medieval até o mundo moderno, apresentando, assim, os aspectos gerais que levavam à mudança de leitura espacial do território produzido a partir da consolidação do mundo urbano, industrial e baseado na lógica da mercadoria.

In The Middle Ground (1980), Margaret Drabble uses an intertextual web to depict the feminine search for identity and psychological integrity in middle age. This paper attempts to identify and analyze the absorption and integration of other texts in The Middle Ground. The dialogue, both in theme and style, with Virginia Woolf's Mrs Dalloway is initially considered, mostly from the perspective of parody. Other confluences are also studied: with Russian fairy tales, with paintings by Hans Holbein, J. B.Vanmour, Van Dyck, Claude Lorrain and Peter de Hooch, and also its references to the whole of Drabble's literary work.

Light microscopy analysis of the mural structure of the common carotid artery, internal carotid artery and external carotid artery in mongrel dog revealed variability in the middle values of vascular diameter and thickness of the intimal plus medial coats and adventitial coat. The vascular diameter did not differ between the internal carotid artery and external carotid artery, but was significantly increased in the common carotid artery from which the other two arteries had origin. The increased thickness of the intimal plus medial coats of the common carotid artery revealed the constant mechanical adjustment of the arterial wall and local shearing stress that occurred among the arterial coats. The adventitial coat of the internal carotid artery was significantly thicker than those of the common carotid and external carotid arteries, with no significant difference noted between the latter arteries. These histomorphometric results were related to the qualitative observations regarding the mural structure of the three arteries analyzed, especially regarding to the increased thickness and structural complexity of the adventitial coat of the internal carotid artery. Perhaps it acted as an external protective sheath of the vascular wall during its long course until the carotid channel. © 2006 Sociedad Chilena de Anatomía.

The objective of the present research was to investigate the ultrastructural peculiarities of the aortic wall of the rat. Seven young adult rats were used, from which fragments of the infrarenal abdominal aorta were collected. After collection, the vascular segments were fixed and sent for analysis by scanning electron microscope. The elastic lamellae appear interposed with smooth muscular fibers; this pattern was verified mainly at the medial layer structure. Among the mural elements a well defined interrelationship was established through connective lamellae of the arterial wall. The collagen lamellae mainly provided anchoring among the elastic and smooth muscular constituents. The intimal layer showed special ultrastructural features, such as a non-continuous inner elastic lamina presented in certain sites of the vascular wall, followed by endothelial pores. This mural pattern of the abdominal aorta provided support to vascular functions such as shrinkage among the laminar composition of the arterial layers, also acting in mechanical properties of the vascular wall, such as viscoelasticity and contractility - essential actions to blood vessel hemodynamics.
