The extraocular muscle fibres of the South-American opossum were determined according to their metabolic profiles using NADH-diaforase, and myofibrilar ATPase after pre-incubation in both acid (pH 4.3) and alkaline (pH 10.4) media. Three muscles were selected to study the arrangement of the fibres (obliquous dorsalis, rectus dorsalis and rectus lateralis muscles). It was demonstrated that they are organized in two layers: the orbital layer composed by small diameter fibres and the global layer with three-times thicker fibres than the former. The global layer has three fibre types: white, red and intermediate; while the orbital layer presents two fibre types, which react differently to the ATPase.

Nelle epatopatie croniche l’estensione della fibrosi è il principale determinante della prognosi. Sebbene la biopsia epatica rimanga il gold standard ai fini di una stadiazione, il crescente interesse nei confronti di metodi diagnostici non invasivi di fibrosi ha portato allo sviluppo di diversi modelli predittivi basati su parametri clinicolaboratoristici quali Fibrotest, indice APRI, indice Forns. Gli scopi dello studio sono: di stabilire l’accuratezza di un’analisi con rete neurale artificiale (ANN), tecnica di cui è stata dimostrata l’efficacia predittiva in situazioni biologiche complesse nell’identificare lo stadio di fibrosi, di confrontarne i risultati con quelli ottenuti dal calcolo degli indici APRI e Forns sullo stesso gruppo di pazienti e infine di validarne l’efficacia diagnostica in gruppi esterni.

Oncological patients are submitted to invasive exams in order to obtain an accurate diagnosis; these procedures may cause maladaptative reactions (fear, anxiety and pain). Particularly in breast cancer, the most common diagnose technique is the incisional biopsy. Most of the patients are unaware about the procedure and for that reason they may focus their thoughts on possible events such as pain, bleeding, the anesthesia, or the later surgical wound care. Anxiety and pain may provoke physiological, behavioral and emotional complications, and because of this reason, the Behavioral Medicine trained psychologist takes an active role before and after the biopsy. The aim of this study was to evaluate the effect of a cognitive-behavioral program to reduce anxiety in women submitted to incisional biopsy for the first time. There were 10 participants from the Hospital Juárez de México, Oncology service; all of them were treated as external patients. The intervention program focused in psycho-education and passive relaxation training using videos, tape-recorded instructions and pamphlets. Anxiety measures were performed using the IDARE-State inventory, and a visual-analogue scale of anxiety (EEF-A), and the measurement of blood pressure and heart rate). Data were analyzed both intrasubject and intersubject using the Wilcoxon test (p≤0.05). The results show a reduction in anxiety (as in punctuation as in ranges) besides, a reduction in the EEF-A.

Es un estudio de tipo descriptivo ya que se pretende evaluar el nivel de actividad del Lupus eritematoso sistémico, el grado de afectación renal por medio de los resultados de los reportes de biopsia renal en pacientes con nefropatía lúpica; transversal ya que se analizará en el período de enero del 2010 a diciembre del 2012. Observacional, no se realizará ninguna acción ni interacción con el paciente; retrospectivo donde se analizarán expedientes de pacientes con diagnóstico de nefropatía lúpica en un período de tres años. El método utilizado fue la revisión de expedientes clínicos, completando la hoja de recolección de datos instrumento creado para la obtención de la información útil para este trabajo de investigación. La investigación está conformada por un total de 45 pacientes con diagnóstico de lupus eritematoso sistémico la mayoría pertenecen al género femenino en una relación de 1: 2.75 masculino: femenino; más de la mitad provienen del área rural; la manifestación clínica más frecuente de enfermedad renal es la hipertensión arterial seguida por el edema, la alteración renal más frecuente por lo que se les realizo biopsia renal fue la proteinuria que representa el 50%, seguido de la elevación de la creatinina; la clasificación según la histopatología de la biopsia renal según la clasificación de la OMS fue la Clase IV que representa más del 40 %.
