Pseudoplagiostoma humilis sp. nov., a New Fungal Species Causing Shoot Blight and Dieback in Anacardium humile in Brazil.

The cajuzinho do cerrado (Anacardium humile-Anacardiaceae), a shrub species native to Brazil, is harvested for multiple uses in food and medicine. Members of a harvesting community, near the municipality of Bonito de Minas, Minas Gerais state, Brazil reported characteristic symptoms of shoot blight and dieback reducing pseudofruit and seed production by this plant. This study aimed to identify the etiological agent of this disease.

Treatment of Tibial Plateau Fractures with a Circular External Fixator: A Comparative Analysis of Two Assembly Methods.

 To compare the functional outcomes of two circular external fixation techniques to treat complex fractures of the proximal end of the tibia.  The present is a retrospective cohort study with 51 patients who underwent surgical treatment for complex fractures of the tibial plateau with a circular external fixator. There were two groups of patients: 12 subjects underwent treatment with the classic assembly technique, and 39 subjects underwent treatment with the simplified technique.

Morphoanatomical Changes in Leaves Associated with Resistance to in Plants of Two Ages.

The fungus infects young tissues of plants until they are two years old in the nursery and field, causing Myrtaceae rust. The characteristics making older eucalypt leaves resistant to and the reason for the low levels of this pathogen in older plants need evaluations. The aim of this study was to evaluate the morphological differences between leaves of different growth stages and two plant ages to propose a visual phenological scale to classify leaves according to their maturation stages and to evaluate the time of leaf maturation for young and adult plants.

Limonene, a Chemical Compound Related to the Resistance of Species to .

The fungus is a major pathogen of spp. that damages mainly early-stage leaves. Resistant clones are the most widely used control measure for the rust disease caused by .

Effects of a Single Dose of Parecoxib on Inflammatory Response and Ischemic Tubular Injury Caused by Hemorrhagic Shock in Rats.

Parecoxib, a selective COX-2 inhibitor, is used to improve analgesia in postoperative procedures. Here we evaluated whether pretreatment with a single dose of parecoxib affects the function, cell injury, and inflammatory response of the kidney of rats subjected to acute hemorrhage. Inflammatory response was determined according to serum and renal tissue cytokine levels (IL-1, IL-1, IL-6, IL-10, and TNF-).

Eucalypt plants are physiologically and metabolically affected by infection with Ceratocystis fimbriata.

Ceratocystis wilt, caused by Ceratocystis fimbriata, is currently one of the most important disease in eucalypt plantations. Plants infected by C. fimbriata have lower volumetric growth, lower pulp yields and reduced timber values.

Controlled Study of Correlation of Biomechanical Profile of Hemiparetic Patients with Distance Travelled in Six Minutes.

The six-minute walking test (6MWT) is used to assess exercise tolerance that is associated with motor function of the lower limbs in hemiparetic patients. It is suggested that, for post-stroke subjects, performance in the 6MWT may be limited by biomechanical and cardiovascular factors. Our aim is to determine the correlation between the six-minute walk distance (6MWD) and the biomechanical profile of hemiparetic patients.

Comparison of thromboprophylaxis patterns in arthroplasty in public and private hospitals.

Objective: To compare therapy for prophylaxis of venous thromboembolism and costs related to hospitalization of patients undergoing total knee and hip replacement within the context of the Brazilian health system.

Methods: A retrospective study of patients undergoing arthroplasty in 2010 in a public hospital and two private hospitals in the state of São Paulo, conducted by means of medical record review. Costs were estimated based on the use of health care resources during hospitalization.

Tumor growth analysis by magnetic resonance imaging of the C6 glioblastoma model with prospects for the assessment of magnetohyperthermia therapy.

Objective: The objective was to establish a pattern of tumor growth of the C6 model of glioblastoma multiform in Wistar rats via magnetic resonance imaging (MRI) for the subsequent verification of tumor volume reduction due to magnetic hyperthermia therapy.

Methods: Young male Wistar rats weighing between 250 and 300 g were used for the C6 model. After the rats were anesthetized (55 mg/ kg ketamine and 11 mg/kg xylazine), C6 lineage tumorigenic cells suspended in culture medium (10(5) cells in 10 microl) were stereotaxically injected into the right frontal cortex (bregma coordinates: 2.

Application of hyperthermia induced by superparamagnetic iron oxide nanoparticles in glioma treatment.

Gliomas are a group of heterogeneous primary central nervous system (CNS) tumors arising from the glial cells. Malignant gliomas account for a majority of malignant primary CNS tumors and are associated with high morbidity and mortality. Glioblastoma is the most frequent and malignant glioma, and despite the recent advances in diagnosis and new treatment options, its prognosis remains dismal.

Magnetohyperthermia for treatment of gliomas: experimental and clinical studies.

Gliomas comprise a group of heterogeneous primary tumors of the central nervous system that originate from glial cells. Malignant gliomas account for the majority of primary malignant CNS tumors and are associated with high morbidity and mortality. Glioblastoma is the most frequent malignant glioma, and despite recent advances in diagnosis and new treatment options, its prognosis remains dismal.

Neuromodulatory effect of creatine on extracellular action potentials in rat hippocampus: role of NMDA receptors.

The creatine (Cr) and phosphocreatine (PCr) system is essential for the buffering and transport of high-energy phosphates. Although achievements made over the last years have highlighted the important role of creatine in several neurological diseases, the adaptive processes elicited by this guanidino compound in hippocampus are poorly understood. In the present study, we showed that creatine (0.

Pro-epileptic effect of alfentanil in rats subjected to pilocarpine-induced chronic epilepsy.

Pharmacological induction of epileptiform activity is a complementary method to study the epileptogenic area in drug-resistant epileptic patients. Among the different activation methods, fentanyl derivatives (e.g.

Physical training reverts hippocampal electrophysiological changes in rats submitted to the pilocarpine model of epilepsy.

Physical exercise and fitness programs in patients with epilepsy are still a matter of controversy. Effects of physical exercise in animals with epilepsy have been demonstrated. To further investigate the possible mechanisms by which physical activity interferes with epileptogenesis, the present work was aimed to study the effect of aerobic exercise on "in vitro" hippocampal electrophysiological parameters observed in rats submitted to the pilocarpine model of epilepsy.
