Effect of phospholipase A inhibitors during infection caused by .

Background: Lipid metabolites play an important role in parasite differentiation and virulence. Studies have revealed that sp. uses prostaglandins to evade innate barriers, thus enabling the parasites to survive inside immune cells.

LED phototherapy in full-thickness burns induced by CO laser in rats skin.

Many studies have been conducted on the treatment of burns because they are important in morbidity and mortality. These studies are mainly focused on improving care and quality of life of patients. The aim of this study was evaluate the LED phototherapy effects in rats skin full-thickness burns induced by CO laser.

Fluorescence visualization efficacy for detecting oral lesions more prone to be dysplastic and potentially malignant disorders: a pilot study.

Background: To analyze the efficacy of fluorescence visualization in early detection of oral early neoplastic processes when used by an inexperienced and an adept oral examiner.

Methods: A dental student and an expert professional in oral diagnosis examined 15 randomly selected patients using conventional oral examination and fluorescence visualization searching for early signs of epithelial dysplasia and oral potentially malignant disorders. Patients detected with oral lesions in any of examinations were submitted to incisional biopsy for definitive diagnosis.

Influence of repeated bouts of eccentric exercise on high-intensity aerobic performance.

[Purpose] It is believed that eccentric high-intensity exercise can decrease performance in subsequent exercise. However, with repetition, the deleterious effects can be minimized. Thus, this study evaluated the influence of repeated bouts of eccentric exercise on subsequent high-intensity aerobic performance.

Oral Manifestations and Dental Management of Epidermolysis Bullosa Simplex.

Epidermolysis bullosa (EB) is a group of hereditary chronic disorders, characterized by fragility of the skin and mucous membranes in response to minor mechanical trauma. The objective of this study was to report the case of a young girl diagnosed with epidermolysis bullosa simplex (EBS), transmitted by an autosomal dominant gene. Cutaneous findings included blisters and dystrophy following minimal friction.

Cardiovascular effects of Zumba(®) performed in a virtual environment using XBOX Kinect.

[Purpose] This study evaluated the acute cardiovascular responses during a session of Zumba(®) Fitness in a virtual reality environment. [Subjects] Eighteen healthy volunteers were recruited. [Methods] The following cardiovascular variables: heart rate, systolic blood pressure, diastolic blood pressure, and double product were assessed before and after the practice of virtual Zumba(®), which was performed as a continuous sequence of five choreographed movements lasting for 22 min.

Effects of feedback on activation of the quadriceps during weight-bearing tasks of the Wii.

[Purpose] This investigation evaluated the effect of real-time feedback on electrical activation of the quadriceps during 3 weight-bearing tasks of the Wii Fit Plus(®). [Subjects] Thirty male healthy volunteers were recruited. [Methods] Activation of the vastus medialis, vastus lateralis, and rectus femoris muscles was recorded during virtual lunge, single leg extension, and single leg reach exercises.

Heart rate detrended fluctuation indexes as estimate of obstructive sleep apnea severity.

In the present study, we aimed at investigating a heart rate variability (HRV) biomarker that could be associated with the severity of the apnea-hypopnea index (AHI), which could be used for an early diagnosis of obstructive sleep apnea (OSA). This was a cross-sectional observational study on 47 patients (age 36 ± 9.2 standard deviation) diagnosed with mild (23.

Experimental full-thickness burns induced by CO2 laser.

Many studies have been conducted on the treatment of burns because they are important in morbidity and mortality. These studies are mainly focused on improving care and quality of life of patients. The aim of this study is the induction of standardized full-thickness burns of the skin of rats using the CO2 laser.

Prediction of crude protein digestibility of animal by-product meals for dogs by the protein solubility in pepsin method.

Animal by-product meals have large variability in crude protein (CP) content and digestibility. In vivo digestibility procedures are precise but laborious, and in vitro methods could be an alternative to evaluate and classify these ingredients. The present study reports prediction equations to estimate the CP digestibility of meat and bone meal (MBM) and poultry by-product meal (PM) using the protein solubility in pepsin method (PSP).

Comparison of the digestive efficiency of extruded diets fed to ferrets (Mustela putorius furo), dogs (Canis familiaris) and cats (Felis catus).

The digestive tract of ferrets is anatomically simple, with no caecum, ileocolic valve or external differentiation between the transition of ileum and colon. The species has a short large intestine that provides minor contributions to the digestive process. Aiming to better understand the digestibility efficiency of ferrets, the present study compared the digestibility of extruded diets with different amounts of macronutrients fed to dogs, cats and ferrets.

Evaluation of the owner's perception in the use of homemade diets for the nutritional management of dogs.

Many dog owners see homemade diets as a way of increasing the bond with their pets, even though they may not have the convenience of commercial diets. Modifications of ingredients, quality and proportion might change the nutritional composition of the diet, generating nutritional imbalances. The present study evaluated how dog owners use and adhere to homemade diets prescribed by veterinary nutritionists over an extended period of time.

Avosentan is protective in hypertensive nephropathy at doses not causing fluid retention.

Multiple studies indicate that endothelin antagonism may have a protective effect for chronic kidney disease. Despite that, clinical studies using avosentan have been halted due to adverse effects including fluid overload. Therefore, we aimed at investigating whether avosentan may have protective effects against hypertensive nephropathy at doses below those inducing fluid-retention.

Mathematical biomarkers for the autonomic regulation of cardiovascular system.

Heart rate and blood pressure are the most important vital signs in diagnosing disease. Both heart rate and blood pressure are characterized by a high degree of short term variability from moment to moment, medium term over the normal day and night as well as in the very long term over months to years. The study of new mathematical algorithms to evaluate the variability of these cardiovascular parameters has a high potential in the development of new methods for early detection of cardiovascular disease, to establish differential diagnosis with possible therapeutic consequences.

Haematological response of curimbas Prochilodus lineatus, naturally infected with Neoechinorhynchus curemai.

This study evaluated the haematological response of curimbas Prochilodus lineatus, naturally infected with Neoechinorhynchus curemai (Acanthocephala: Neoechinorhynchidae). Thirty-seven fish were captured in October 2010 from the Mogi Guaçu River, Porto Ferreira, SP, Brazil. Infected fish presented increased mean corpuscular volume of erythrocytes, and lower thrombocyte and higher monocyte counts than uninfected fish.

The Angiotensin-melatonin axis.

Accumulating evidence indicates that various biological and neuroendocrine circadian rhythms may be disrupted in cardiovascular and metabolic disorders. These circadian alterations may contribute to the progression of disease. Our studies direct to an important role of angiotensin II and melatonin in the modulation of circadian rhythms.
