Force-displacement relationship during anteroposterior mobilization of the ankle joint.

Objective: The purpose of this study was to determinate the correlation between force and displacement during passive anteroposterior mobilization of the talus and the effect of this treatment technique on ankle dorsiflexion range of motion (ROM).

Methods: This is an exploratory, methodological study. Maitland grades III and IV mobilization were applied on the right ankle of 25 healthy subjects (mean age +/- standard deviation, 25.

[Education in health and conceptual interfaces: representations of students of a nursing course].

Article produced from the a doctoral thesis: "The Education in Health in the scenarios of teach-learning: representations of professors and students from the Nursing School of the University Vale of the Acaraú", whose objective was to apprehend the direction of the representations elaborated for professors and students of the Graduation Nursing Course, about Education in Health. The results presented here come from the Free Test of Words Association. It was possible to infer that the novice students' representations are in the nucleus of what is established as common sense, considering the reductionism concept in health, proper form of the biomedical model.

Study of the force applied during anteroposterior articular mobilization of the talus and its effect on the dorsiflexion range of motion.

Objective: The aim of this study was to investigate the behavior of the force applied during the Maitland grade III anteroposterior joint mobilization of the talus and its effect on dorsiflexion range of motion (ROM).

Methods: Two examiners performed measurements of dorsiflexion ROM on both ankles of healthy volunteers using a universal goniometer. The anteroposterior talus mobilization was first applied by examiner A for 30 seconds.

Antiinflammatory effects of natural tetranortriterpenoids isolated from Carapa guianensis Aublet on zymosan-induced arthritis in mice.

Objective: We investigated the antiinflammatory properties of a derived fraction of tetranortriterpenoids (TNTP) obtained from the seeds of Carapa guianensis Aublet.

Material And Methods: Zymosan-induced arthritis and pleurisy in Swiss and C57/Bl6 mice (n = 10 per group). Western blot analysis was performed to analyze nuclear factor-kappaB (NFkappaB) translocation in mice peritoneal macrophages stimulated in vitro with zymosan (500 microg/ml).

Concentration of elastic system fibers in the corpus cavernosum, corpus spongiosum, and tunica albuginea in the rabbit penis.

The corpus cavernosum (CC) extracellular matrix is essential for normal penile erection and is implicated in erectile dysfunction. Although investigations of these issues have used the rabbit CC, organization of its components is not well known to date. We characterized and quantified the volumetric density (Vv) of the elastic system fibers in the corpus spongiosum (CS), CC and tunica albuginea (TA) of the rabbit penis.

Adult Citrus Leafminers (Phyllocnistis citrella) Are Not Efficient Vectors for Xanthomonas axonopodis pv. citri.

Interest in the interaction between the citrus leafminer (Phyllocnistis citrella) and citrus bacterial canker, caused by Xanthomonas axonopodis pv. citri, has increased as a greater incidence and severity of canker-diseased plants was observed in groves infested with the citrus leafminer. To determine whether adults of the citrus leafminer could act as vectors of citrus canker, we investigated two potential mechanisms for direct spread by leafminer adults using experimental microcosms.

Immunohistochemical analysis of smooth muscle cells and volumetric density of the elastic system fibers of wild boar (Sus scrofa) penis.

The purpose of the present study was to verify the smooth muscle cell distribution and elastic system fibers volumetric density (Vv) in the corpus spongiosum and corpus cavernosum of the wild boar penis. Adult wild boars (n=13) were used. The penile mid shaft fragments were fixed with 4% phosphate buffered formalin solution and/or Bouin's liquid during 24-48 h, and processed using standard histological techniques.

Volumetric density of elastic and reticular fibers in transition zone of controls and patients with benign prostatic hyperplasia.

Objectives: To analyze the volumetric density (Vv) of elastic and reticular fibers in the transition zone of controls and patients with benign prostatic hyperplasia (BPH).

Methods: Prostatic tissue samples were obtained from 25 patients (age range 63 to 79 years, mean 68) with clinical symptoms of bladder outlet obstruction who had undergone open prostatectomy. The control group was composed of 25 transition zone samples from prostates obtained during autopsy of adults aged younger than 30 years (killed in accidents).

Prostatic epithelial and luminal area in the transition zone acini: morphometric analysis in normal and hyperplastic human prostate.

Objective: To analyse quantitatively the acini and changes in the acinar epithelium and lumen in the transitional zone of normal and hyperplastic human prostates.

Patients And Methods: Tissue samples of the transitional zone were taken from prostates with benign prostatic hyperplasia (BPH) obtained from 20 patients with clinical symptoms of bladder outlet obstruction who underwent open prostatectomy. The control tissue comprised 20 transitional zones of prostates obtained during autopsy of adults aged < 30 years (killed in accidents).

[Clinical aspects of neurocysticercosis at semi-desert region of Brazilian northeast].

Case sheets of 44 patients with neurocysticercosis, coming from Campina Grande and others cities of Para ba state, examined between 1990 - 2001 were analyzed. The average age (SD +/-) was 20.6 +/- 14.

[Living a socio-cultural approach in nursing education].

The paper describes a teaching experience linking an undergraduate course and Master's degree course strictu sensu. The aim is to reflect on the social-cultural approach in nursing teaching and the relationship between teacher and students in the classroom. The subject of the study were students and a teacher from the discipline Philosophical Anthropology (graduate course) and student of the discipline Methodology of nursing teaching (master's course).

Stromal and acinar components of the transition zone in normal and hyperplastic human prostate.

Objective: To analyse the histological components of the transition zone in both normal human prostate and benign prostatic hyperplasia (BPH), and to determine the volumetric density (Vv) of the different elements (connective tissue, smooth muscle cells, acini and total stroma).

Materials And Methods: Samples of BPH tissue from the transition zone were obtained from 16 patients with clinical symptoms of bladder outlet obstruction who underwent open prostatectomy. The control samples comprised 16 transition zone samples from prostates obtained during necropsy of adults aged < 30 years (killed in accidents).

[Acute lymphoblastic leukemia in childhood. A 10-year experience with the DFCI 81-01 protocol].

Acute lymphoblastic leukemia is the most frequently encountered pediatric cancer. Approximately 70% of cases can be cured of the disease. In this article, we describe the experience of our Center in the last ten years with a treatment protocol adapted from protocol DFCI 81-01 (from the Dana Farber Cancer Institute, Boston).

Studies on the mechanisms involved in antigen-evoked pleural inflammation in rats: contribution of IgE and complement.

Immunoglobulin E (IgE) has been shown to play a critical role in the allergic late-phase reaction, which is marked by intense leukocyte infiltration and edema. In this study we assessed the allergic pleural inflammation triggered by intrapleural (i.pl.

Histamine-potentiating activity in rat anaphylactic pleural fluid: role of serotonin.

The identity of the histamine-potentiating activity detected in the rat anaphylactic pleural washing was investigated. Wistar rats of both sexes, weighing 150-200 g, were sensitized by injecting subcutaneously (sc) a mixture of ovalbumin and Al(OH)3 14 days before allergen challenge. In sensitized rats, intrapleural (ipl) injection of ovalbumin (12 micrograms/cavity) caused an intense protein exudation.

Fine-needle aspiration cytology as a tool for the early detection of testicular relapse of acute lymphoblastic leukemia in children.

Fine-needle aspiration cytology (FNAC) of the testis was done in 31 children (33 aspirates) with acute lymphoblastic leukemia (ALL) either as part of an end-therapy protocol (Group I, n = 20) or because of clinical suspicion of testicular relapse (Group II, n = 13). In Group I, none of the smears showed evidence of leukemic cells. However, two of these patients developed subsequent testicular relapse within 1 yr and were considered false-negative cases.
