Anacardium occidentale L. (cajueiro) in the healing of skin wounds: an experimental study in rats.

Purpose: To analyze the effects of Anacardium occidentale Linn on the healing of skin wounds.

Methods: Twenty Wistar male rats were distributed into four groups (with five animals each one): negative control group (NCG), treated with saline solution; cashew tree group (CG), treated with hydroalcoholic extract of the bark of A. occidentale Linn; manipulated cashew tree group (MCG), with the ointment of extract of the bark of A.

Anatomical description of the ventral and dorsal cervical rootlets in rats: A microsurgical study.

Purpose: To describe the anatomical aspects of the cervical rootlets and to quantify the number of rootlets that compose C1 to T1.

Methods: Twenty male rats were used in this study. The dorsal rootlets from C1 to T1 were analyzed.

A new anesthetic protocol to medullary nerve roots access in rats.

Purpose: To describe a new anesthetic protocol medullary and nerve roots access and in Rattus norvegicus.

Methods: Seventy female Wistar rats (n=70) were used. The animals were randomly divided into two laminectomy groups: cervical (n=40) and thoracic (n=30).

Comparative angiotomographic study of swine vascular anatomy: contributions to research and training models in vascular and endovascular surgery.

Background: Medium and large animal models allow researchers to evaluate the efficacy and safety of cardiovascular procedures in systems that resemble human anatomy and can be used to simulate scenarios for training purposes. Although porcine models have been used extensively, many physiological and anatomical features remain unknown or only superficially described.

Objectives: To describe the normal porcine vascular anatomy on computed tomography scans, compare it to human vascular anatomy, and discuss the application of porcine models for open and endovascular procedures.

Image-guided study of swine anatomy as a tool for urologic surgery research and training.

Purpose: To describe the anatomy of the swine urinary system using computed tomography and to discuss the role of this animal as an experimental model for urological procedures.

Methods: Three male Landrace pigs underwent computed tomography and the anatomy of the urinary system and renal circulation was analyzed and described.

Results: In all animals, 2 kidneys, 2 ureters and one bladder were identified.

Improving a training model for vascular surgical techniques.

We describe a low-cost model for training vascular surgical techniques. The model is constructed from cylindrical latex balloons filled with gelatin and fixed to a board for support. Arterial sutures, end-to-side and end-to-end anastomoses, patch, vascular shunt placement, and thromboembolectomy were simulated.

Influence of tramadol on functional recovery of acute spinal cord injury in rats.

Purpose: To evaluate the influence tramadol on functional recovery of acute spinal cord injury in rats.

Methods: Ten rats were divided into two groups (n = 5). All animals were submitted by a laminectomy and spinal cord injury at eighth thoracic vertebra.

Therapeutic effect of andiroba oil (Carapa guianensis Aubl.) against oral mucositis: an experimental study in golden Syrian hamsters.

Objectives: The aim of this study was to investigate the healing activity of andiroba (Carapa guianensis Aubl.) against oral mucositis (OM) induced by 5-fluorouracil in golden Syrian hamsters.

Materials And Methods: A total of 122 animals were randomized and divided into six groups: andiroba oil 100%, andiroba oil 10%, andiroba oil 10% refined, no treatment group, all n = 28; and negative control (NC) and cyclophosphamide (CPA) groups, both n = 5.

Evaluation of blood pressure in feline night monkeys (Aotus azarae infulatus) under different restraint protocols.

Background: Feline night monkeys are very susceptible to stress when handled, and because of that, the use of anesthetic and physical restraint methods should be carefully evaluated. To ensure a safer anesthesia to the animals the present study aimed to observe the influence of four restraint protocols in the blood pressure of Aotus azarae infulatus.

Methods: Blood pressure was obtained from 10 animals subjected to restraining protocols using tiletamine and zolazepam, isoflurane, ketamine and midazolam, and physical restraint and results were evaluated to determine their effect on this exam.

Effective diagnosis of Alzheimer's disease by means of large margin-based methodology.

Background: Functional brain images such as Single-Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) have been widely used to guide the clinicians in the Alzheimer's Disease (AD) diagnosis. However, the subjectivity involved in their evaluation has favoured the development of Computer Aided Diagnosis (CAD) Systems.

Methods: It is proposed a novel combination of feature extraction techniques to improve the diagnosis of AD.
