The genetic variation among nine soybean-originating isolates of Colletotrichum truncatum from different Brazilian states was studied. Nitrate non-utilizing (nit) mutants were obtained with potassium chlorate and used to characterize vegetative compatibility reactions, heterokaryosis and RAPD profile. Based on pairings of nit mutants from the different isolates, five vegetative complementation ...
Considering the absence of standards for culture collections and more specifically for biological resource centers in the world, in addition to the absence of certified biological material in Brazil, this study aimed to evaluate a Fungal Collection from Fiocruz, as a producer of certified reference material and as Biological Resource Center (BRC). For this evaluation, a checklist based on the r...
Nitrate uptake in Neurospora crassa has been investigated under various conditions of nitrogen nutrition by measuring the rate of disappearance of nitrate from the medium and by determining mycelial nitrate accumulation. The nitrate transport system is induced by either nitrate or nitrite, but is not present in mycelia grown on ammonia or Casamino Acids. The appearance of nitrate uptake activit...
Background: A neem-based conditioner lotion (ONC) used against head lice was previously tested clinically and shown to be relatively ineffective. To improve the activity against lice and their eggs, it was reformulated into a silicone vehicle (NNC) as part of a project to improve pediculicidal medical devices. An ultrasound nit comb was also developed to be used in conjunction with the neem lot...
Islet transplantation has considerable potential as a cure for diabetes. However, the difficulties that arise from inflammation and the immunological rejection of transplants must be addressed for islet transplantation to be successful. Alpha 1-antitrypsin (AAT) inhibits the damage on β cells caused by inflammatory reactions and promotes β-cell survival and proliferation. This protein also indu...
BACKGROUND This study was the first to evaluate the therapeutic outcomes of recombinant human brain natriuretic peptide (rhBNP) versus nitroglycerin (NIT) in patients with heart failure (HF). METHODS The electronic databases were systematically searched to identify available studies. The pooled odds ratios (ORs) and their 95% confidence intervals (95% CIs) were analyzed to assess the mortalit...
BACKGROUND Interventional closure of patent arterial duct has become an accepted alternative to surgical closure. Clinical trial with "Nit-Occlud® PDA-R". METHODS AND RESULTS To assess the safety and efficacy of the device, we performed a prospective clinical study between June, 2009 and December, 2010 in La Paz, Bolivia. In all, 29 - 22 female patients and 7 male patients - out of 59 patient...
In this paper, we have demonstrated successfully a new approach for evaluating the hot-carrier reliability in submicron LDD MOSFET with various drain engineering. It was developed based on an efficient charge pumping measurement technique along with a new criterion. This new criterion is based on an understanding of the interface state (Nit) distribution, instead of substrate current or impact ...
Chlamydomonas is a popular genetic model system for studying many cellular processes. In this report, we describe a new approach to isolate Chlamydomonas genes using the cloned nitrate reductase gene (NIT1) as an insertional mutagen. A linearized plasmid containing the NIT1 gene was introduced into nit1 mutant cells by glass-bead transformation. Of 3000 Nit+ transformants examined, 74 showed mo...
