Orbitoethmoidal impacted injury by kitchen knife causing abducens nerve palsy

Introduction: Impacted knife injuries in the maxillofacial region are rare and infrequently reported. In cases of injury involving orbit or eye, these reports are even rarer. Discussion: Damage to the orbital contents may result in a rupture of the globe, extraocular muscle injury, lacrimal gland damage, and others. Orbital foreign bodies are not only difficult to detect, and clinical features vary according to its size, characteristics, shape, penetrating method, and site. In this report, a case of abducens nerve palsy after orbitoethmoidal knife injury is presented. © 2010 Springer-Verlag.

Noninvasive aspergillosis as a maxillary antrolith: report of a rare case.

Maxillary antrolithiasis is characterized by masses of tissue of endogenous or exogenous origin that calcify within the maxillary sinuses. Aspergillosis is a fungal disease in which the maxillary sinus is a primary site of infection. Aspergillosis mycetoma, its noninvasive form, is the most prevalent modality of the disease in the maxillary sinuses. In approximately half of the cases reported in the literature, calcification of the fungal mycelia, which later became antroliths, was verified. This article reports a rare case of the accidental discovery of a maxillary antrolith associated with noninvasive aspergillosis in an immunocompetent and asymptomatic 56-year-old woman. The diagnosis and therapeutic procedures used in treating the patient are discussed as well as the probable iatrogenic origin of the fungal pathology.

O Método de Kane aplicado a um modelo de corpo humano para obtenção da pressão intradiscal na coluna lombar

Nos últimos anos tem surgido vários métodos para se estudar sistemas multicorpos. A vantagem destes métodos é a obtenção das equações do movimento de forma mais fácil e precisa. Robôs, manipuladores, mecanismos, satélites, máquinas em geral e sistemas biomcânicos, pelas suas características, podem ser vantajosamente tratados por formalismo multicorpo, mas precisamente, o método de Kane a um modelo do corpo humano, com a finalidade de se determinar a pressão intradiscal entre as vértebras L4/L5 da coluna lombar, em algumas atividades normais de vida diária, como: sentar, abaixar, pegar e elevar cargas, realizar movimentos de flexão e extensão. Pretendeu-se, também obter os esforços internos nas diversas articulações deste modelo. A pressão intradiscal representa um parâmetro importante para caracterizar a sobrecarga na coluna, podendo ter relação com a degeneração do disco intervertebral, o que produz muita dor em indivíduos. Inicialmente, o modelo foi proposto e o método de Kane foi aplicado para se obter as equações do movimento. Para resolvê-las, foi necessário realiza a filmagem de um sujeito realizando as atividades citadas, a fim de se obter as equações das trajetórias dos diversos segmentos do corpo humano. Após a simulação, os parâmetros desejados foram obtidos e comparados com valores experimentais citados na literatura.

Dinâmicas de segregação sócio-espacial no meio urbano

In this study we discuss a range of topics related to urban development from the perspective of connection points between the existence of the individual subjects’ lives. In this connection we identified the signs that express an articulation among subjectivity processes and conditions for interference in the real world, relying on circumscribed remarks about spatial configurations and its uses. This way, the substance of our research is structured upon the concept of fashion brands operating new dynamics of urban lifestyles, a strengthened reliance on the physical body’s appearance and the profusion of a supposed “I”, presented as a spectacle. Taking these assertions as new “trends” on building view-points and contemporary cities, we discuss the implications of these currents on how people gather and organize themselves in the urban landscape, making an effort to comprehend how these vogues reverberate on the (re)production of increasingly segregated cities

Multimethodological study of molecular recognition phenomena

The study of the bio-recognition phenomena behind a biological process is nowadays considered a useful tool to deeply understand physiological mechanisms allowing the discovery of novel biological target and the development of new lead candidates. Moreover, understanding this kind of phenomena can be helpful in characterizing absorption, distribution, metabolism, elimination and toxicity properties of a new drug (ADMET parameters). Recent estimations show that about half of all drugs in development fail to make it to the market because of ADMET deficiencies; thus a rapid determination of ADMET parameters in early stages of drug discovery would save money and time, allowing to choose the better compound and to eliminate any losers. The monitoring of drug binding to plasma proteins is becoming essential in the field of drug discovery to characterize the drug distribution in human body. Human serum albumin (HSA) is the most abundant protein in plasma playing a fundamental role in the transport of drugs, metabolites and endogenous factors; so the study of the binding mechanism to HSA has become crucial to the early characterization of the pharmacokinetic profile of new potential leads. Furthermore, most of the distribution experiments carried out in vivo are performed on animals. Hence it is interesting to determine the binding of new compounds to albumins from different species to evaluate the reliability of extrapolating the distribution data obtained in animals to humans. It is clear how the characterization of interactions between proteins and drugs determines a growing need of methodologies to study any specific molecular event. A wide variety of biochemical techniques have been applied to this purpose. High-performance liquid affinity chromatography, circular dichroism and optical biosensor represent three techniques that can be able to elucidate the interaction of a new drug with its target and with others proteins that could interfere with ADMET parameters.
