Upright balance control strategies during pregnancy.

Background: Morphological and physiological changes during pregnancy are considered to interfere with the mechanisms of postural control and potentially increase the risk of falling. A clear understanding of these mechanisms is important to improve pre-natal care and reduce the fall risk in this population.

Objectives: This study focused on investigating how pregnancy affects postural control in each trimester of pregnancy by analyzing pelvic inclination and body sway behavior.

The context of leprosy in Brazil-Paraguay border.

In Brazil, leprosy is endemic in three regions: the North, Northeast, and Mid-West. Counties with contiguous binational urban areas are characterized by a constant flow of people, goods, and services, which facilitates the transmission of diseases and influences the epidemiological profile of leprosy. The purpose of this study was to examine territorial differences in relation to the incidence of leprosy, focusing on border counties with contiguous binational urban areas or otherwise.

Biocompatibility and osteogenesis of the castor bean polymer doped with silica (SiO2) or barium titanate (BaTiO3) nanoparticles.

Purpose: To evaluate the biocompatibility and osteogenesis of castor oil polymer doped with SiO2 or BaTiO3 nanoparticles.

Methods: Twenty four male rats Wistar were submitted to bone defect filled with castor oil polymer. The animals were distributed in two experimental groups had been formed with 12 animals each: Group 1 - Castor oil polymer doped with 0.

Spatial distribution and environmental factors associated to phlebotomine fauna in a border area of transmission of visceral leishmaniasis in Mato Grosso do Sul, Brazil.

Background: Mato Grosso do Sul has been undergoing a process of urbanization which results in loss of native vegetation. This withdrawal makes vectors of man and domestic animals closer, causing changes in the epidemiology of diseases such as American Visceral Leishmaniasis. The aim of the study was to evaluate the phlebotomine fauna and environmental issues related to the transmission of AVL in Ponta Porã, Mato Grosso do Sul, between 2009 and 2010.

Effects of pre- or post-exercise low-level laser therapy (830 nm) on skeletal muscle fatigue and biochemical markers of recovery in humans: double-blind placebo-controlled trial.

Objectives: The purpose of this study was to investigate the effect of low-level laser therapy (LLLT) before and after exercise on quadriceps muscle performance, and to evaluate the changes in serum lactate and creatine kinase (CK) levels.

Methods: The study was randomized, double blind, and placebo controlled.

Patients: A sample of 27 healthy volunteers (male soccer players) were divided into three groups: placebo, pre-fatigue laser, and post-fatigue laser.

Evaluation of oxidative stress in mice subjected to aerobic exercise.

Purpose: To evaluate the influence of aerobic exercise on oxidative stress in mice.

Methods: The study included twenty female mice Mus musculus-Swiss divided into two groups: sedentary control (GA) and exercise (GB), each containing ten animals. All animals underwent an adaptation period of seven days isolated in individual boxes.

Castor oil polyurethane containing silica nanoparticles as filling material of bone defect in rats.

Purpose: To evaluate the biologic behavior of the castor polymer containing silica nanoparticles as a bone substitute in diafisary defect.

Methods: Twenty seven male Rattus norvegicus albinus Wistar lineage were submitted to bone defect filled with castor oil polymer. Three experimental groups had been formed with nine animals each: (1) castor oil polymer containing only calcium carbonate; (2) castor oil polymer with calcium carbonate and doped with 5% of silica nanoparticles; (3) castor polymer with calcium carbonate doped with 10% of silica nanoparticles; 3 animals of each group were submitted to euthanasia 15, 30 and 60 days after experimental procedure, and their femurs were removed to histological evaluation.

Lung apoptosis after intra-pulmonary instillation of Benzo(a)pyrene in Wistar rats.

Purpose: To evaluate the influence of pulmonary instillation of Benzo[a]pyrene in lung apoptosis of Wistar rats.

Methods: Male Rattus norvegicus albinus, Wistar lineage was carried through an intra-pulmonary instillation of the Benzo[a]pyrene (B[a]P) dilution in alcohol 70%. Three experimental groups had been formed with 08 animals each: Control Group (Alcohol 70%); B[a]P Group 40 mg/kg; e B[a]P Group 80mg/kg, submitted to euthanasia 16 and 18 weeks after the experimental procedure.

Effect of laser therapy (660 nm) on recovery of the sciatic nerve in rats after injury through neurotmesis followed by epineural anastomosis.

The aim of this study was to analyze the influence of aluminum gallium arsenide (AlGaAs) laser (660 nm) on the myelin sheath and functional recovery of the sciatic nerve in rats. The sciatic nerves of 12 Wistar rats were subjected to injury through neurotmesis and epineural anastomosis, and the animals were divided into two groups: group 1 was the control and group 2, underwent low-level laser therapy (LLLT). After the injury, AlGaAs laser at 660 nm, 4 J/cm(2), 26.

Experimental model of pulmonary carcinogenesis in Wistar rats.

Purpose: To elaborate an experimental model of pulmonary carcinogenesis in Wistar rats.

Methods: Male Rattus norvegicus albinus, Wistar lineage were carried through an intra-pulmonary instillation of the Benzo[a]pyrene (B[a]P) dilution in alcohol 70%, a polycyclic aromatic hydrocarbon widely known by its power of tumoral induction. Three experimental groups had been formed with 08 animals each: Control Group (Alcohol 70%); B[a]P Group 10 mg/kg; e B[a]P Group 20mg/kg, submitted to euthanasia 08, 10, 12 and 14 weeks after the experimental procedure.

Usefulness of argyrophilic nucleolar organizer regions in detection of lung cells alterations after benzo[a]pyrene instillation.

Purpose: To verify the relationship between AgNOR expression and lung tissues changes of Wistar rats after pulmonary instillation of benzo[a]pyrene (B[a]P).

[Influence of the breathing time increase in the pulmonary ventilation of patients submitted to mechanical ventilation in controlled pressure mode].

Background And Objectives: The mechanical ventilator support is one of the main used modalities of support in intensive therapy. In the modality of predetermined pressure, the maximum pressure is regulated, but the current volume (V T) is a complex function of the applied pressure and its speed to reach the pressure-target, of the available breathing time and the resistance to the breath. This paper has as objective to evaluate the influences of the increment of the breathing time in the pulmonary ventilation.
