Nephrotoxicity is the main side effect of antibiotics such as gentamicin. Preconditioning has been reported to protect against injuries as ischemia/reperfusion. The objective of the present study was to determine the effect of preconditioning with gentamicin on LLC-PK1 cells. Preconditioning was induced in LLC-PK1 cells by 24-h exposure to 2.0 mM gentamicin (G/IU). After 4 or 15 days of preconditioning, cells w...
Carpotroche brasiliensis is a native Brazilian tree belonging to the Oncobeae tribe of Flacourtiaceae. The oil extracted from its seeds contains as major constituents the same cyclopentenyl fatty acids hydnocarpic (40.5%), chaulmoogric (14.0%) and gorlic (16.1%) acids found in the better known chaulmoogra oil prepared from the seeds of various species of Hydnocarpus (Flacourtiaceae). These acids are known to be...
Several techniques can be used to improve surface properties. These can involve changes on the surface chemical composition (such as alloying and surface welding processes) or on the surface microstructure, such as hardening and melting. In the present work surface melting with a 3kW CO2 cw laser was done to alter surface features of an AISI 304 stainless steel. Microstructure characterisation was done by optic...
Os autores apresentam dois casos de polineuropatia carencial (PC) entre os índios Xavantes, em que o arroz era o alimento exclusivo no caso 1 e quase exclusivo no caso 2. O arroz consumido por esses índios era o beneficiado ou despolpado. A intoxicação pelo cianeto da mandioca ou de outros vegetais foi afastada. RELATO DOS CASOS. Foram observados em suas aldeias dois índios com 18 e 25 anos, com história progre...
To investigate the possibility of local antigen presentation within the peripheral nerve in amyotrophic lateral sclerosis (ALS), cryostat sections of 83 peripheral nerve biopsies were stained for the demonstration of HLA-DR using a monoclonal antibody. Forty samples showed increased expression of HLA-DR in endoneurium. The phenotypic characteristics of the HLA-DR positive cells are chiefly Schwann cells, using ...
O presente trabalho teve como objetivo verificar os efeitos de diferentes níveis de água, aplicada na forma de gotejamento, em cultura de pimentão (Capsicum annuum L.) em condições de casa-de-vegetação coberta com lençol de polietileno. O cultivar utilizado foi "Agronômico 10G". O delineamento empregado foi inteiramente ao acaso, com quatro tratamentos e oito repetições. As irrigações eram feitas quando consumi...
Dengue is known to produce a syndrome involving muscles, tendons and joints. The hallmark of this syndrome is severe myalgia but includes fever, cutaneous rash, and headache. The neuromuscular aspects of this infection are outlined only in isolated reports, and the muscle histopathological features during myalgia have not been described. In order to ascertain the actual neuromuscular involvement in dengue and b...
Descrevemos 17 pacientes (12m, 5f) com idades que variaram de 1 a 24 anos (mediana 6 anos) com distrofia muscular congênita (DMC), que foram estudados do ponto de vista genético, clínico, laboratorial, eletrofisiológico e anátomo-patológico. A apresentação segundo a herança foi da forma esporádica (76,5%) ou possivelmente autossômica recessiva (23,5%). A diminuição da movimentação fetal intra-uterina foi referi...
