We aimed to characterize the genetic diversity of drug-resistant Mycobacterium tuberculosis (MTb) clinical isolates and investigate the molecular epidemiology of multidrug-resistant (MDR) tuberculosis from Minas Gerais State, Brazil. One hundred and four MTb clinical isolates were assessed by IS6110-RFLP, 24-locus mycobacterial interspersed repetitive units variable-number tandem repeats (MIRU-VNTR), TB-SPRINT (simultaneous spoligotyping and rifampicin-isoniazid drug-resistance mutation analysis) and ...

Large amounts of photocatalysts are needed for the generation of solar hydrogen (H2) and eco-friendly synthetic alternatives are essential. Here, we use glycerol as solvent and reducing agent, and food grade corn starch as stabilizing agent for the preparation of silver nanoparticles (Ag NPs) by microwave irradiation. The Ag NPs were also synthesized using various proportions of glycerol/water mixtures. The Ag NPs were loaded onto commercial TiO2 NPs to study the photogeneration of H2. Characterization ...

The aim of this study was to use the fluorescence in situ hybridization (FISH) technique to test the hypothesis of qualitative and quantitative differences of 8 periodontopathogens between pregnant and non-pregnant women. This cross-sectional study included 20 pregnant women in their second trimester of pregnancy and 20 non-pregnant women. Probing depth, bleeding on probing, clinical attachment level, and presence of calculus were recorded. Subgingival plaque samples were collected and the FISH technique ...

Following a critical review of the utilisation of chelating reagents (hydroxamates) in minerals flotation, results of a series of experiments performed in the presence of an experimental commercial hydroxamate as collector, at bench scale with two different ores and in a microflotation cell with several combinations of minerals (most of them "sparingly soluble minerals") are presented. The conclusion is that the selectivity of minerals flotation with hydroxamates depends on a balance between the solubility ...

Maize is an important food source worldwide and is of considerable industrial importance. Low maize yields are mostly due to low soil fertility, so expensive mineral fertilizers are often used to offset the lack of nutrients. Poultry litter (PL) is one of the most valuable and phosphorous-rich animal wastes. However, PL usually contains veterinary antibiotic residues, particularly fluoroquinolones (FQs), which may alter soil microorganism diversity and resistance patterns. In this study, we aimed ...

Acanthamoeba is a genus of free-living amoebas distributed worldwide. Few studies have explored the interactions between these protozoa and their infecting giant virus, Acanthamoeba polyphaga mimivirus (APMV). Here we show that, once the amoebal encystment is triggered, trophozoites become significantly resistant to APMV. Otherwise, upon infection, APMV is able to interfere with the expression of a serine proteinase related to amoebal encystment and the encystment can no longer be triggered.

Boron (B) deficiency causes a wide array of symptoms, not only among species of palms, but also within a single species (i.e. Cocos nucifera). A better understanding of the effects of B deficiency in coconut will be important to try optimizing a rational fertilization management in coconut plants. Thus, modification of PSII photochemistry (using a group of fluorescence parameters, called the JIP- test, that quantify the stepwise flow of energy through Photosystem II) and gas-exchange in boron deficient ...

Deletion of SIT4 phosphatase decreased the pyruvate decarboxylase activity, which is essential for directing the glucose flux to ethanol production. Concomitantly, a reduction in the fermentative capacity was observed. As pyruvate decarboxylase expression was not altered, its post-translational phosphorylation was studied. Immunoblot analyses using anti-phosphoserine antibodies against the affinity-purified Pdc1p showed that Pdc1p is a phosphoenzyme. Dephosphorylation of Pdc1p by alkaline phosphatase ...
