Trypanosoma cruzi, the etiologic agent of Chagas disease, undergoes drastic metabolic changes when it transits between a vector and mammalian hosts. Amino acid catabolism leads to the production of ammonium (NH4+), which needs to be detoxified. However, T. cruzi does not possess a urea cycle, and it is unknown how intracellular levels of ammonium are controlled. In this work, we identified an i...

This study was conducted to evaluate plant response of Brachiaria brizantha cv. MG5 to nitrogen (N) forms and different pH's of nutrient solution. In this study, under controlled conditions in growth chamber with hydroponics culture, seedlings after germination were treated with different N forms as nitrate, ammonium, and ammonium nitrate, as well as with different nutrient solution pH's. A sol...

Nitrates have been used as an antimicrobial agent in foods for hundreds of years. As a result there is extensive literature on their mode of activity in the food sciences and other such diverse fields as gastroenterology, the pulmonary sciences, and cancer research but minimal research exists in the dental sciences. This manuscript will describe how nitrate present in green leafy vegetables is ...

Implicated as a stratospheric ozone-depleting compound, methyl bromide (MeBr) is being phased out despite being considered to be the most effective soil fumigant. Its alternatives, i.e., 1,3-dichloropropene (1,3-D, which includes cis and trans isomers), chloropicrin (CP), and methyl iodide (MeI), have been widely used. High emissions of MeI from fumigated soil likely put farm workers and other ...

The aquatic ecotoxicity of chemicals involved in the manufacturing process of thin film transistor liquid crystal displays was assessed with a battery of four selected acute toxicity bioassays. We focused on tetramethylammonium hydroxide (TMAH, CAS No. 75-59-2), a widely utilized etchant. The toxicity of TMAH was low when tested in the 72 h-algal growth inhibition test (Pseudokirchneriellia sub...

A reliable method for the determination of iodine and molybdenum in milk samples, using alkaline digestion with tetramethylammonium hydroxide and hydrogen peroxide, followed by quadrupole ICP-MS analysis, has been developed and tested using certified reference materials. The use of He+O2 (1.0 ml min(-1) and 0.6 ml min(-1)) in the collision-reaction cell of the mass spectrometer to remove (129)X...

We report on solid-state mesoscopic heterojunction solar cells employing nanoparticles (NPs) of methyl ammonium lead iodide (CH(3)NH(3))PbI(3) as light harvesters. The perovskite NPs were produced by reaction of methylammonium iodide with PbI(2) and deposited onto a submicron-thick mesoscopic TiO(2) film, whose pores were infiltrated with the hole-conductor spiro-MeOTAD. Illumination with stand...

Lysosomes were purified approximately 40-fold from rat kidney cortex by differential and Percoll density gradient centrifugation. In a sucrose medium, the lysosomes quenched the fluorescence of the potential sensitive dye diS-C3-(5) (3,3'-dipropylthiocarbo-cyanine iodide) in a time-dependent manner, indicating that the dye accumulates within the lysosomal interior. After treatment of the lysoso...
