Synthesis and virtual screening of bis-(4-(tert-butyl)-N-(methylcarbamothioyl) benzamide)-Iron (III) complex as an anticancer candidate [PDF]
Pharmaciana, 2021 Thiourea derivatives were much used in drug discovery and drug-making, such as for an anticancer. The formation of drug complexes can increase lipophilicity through chelation formation, and the drug action is significantly upward due to the effective ...

Characterization and discrimination of soils by their reflected electromagnetic energy [PDF]
Pesquisa Agropecuária Brasileira, 2002 The objective of this work was to verify if reflected energy of soils can characterize and discriminate them. A spectroradiometer (Spectral reflectance between: 400-2,500 nm) was utilized in laboratory. The soils evaluated are located in Bauru region, SP,

Speech therapy changes blood circulation and oxygenation in the brain and muscle: a near-infrared spectrophotometry study [PDF]
, 2011 Recently it has been shown that artistic speech therapy (AST) has effects on heart rate variability. The aim of this pilot study was to investigate whether AST also affects hemodynamics and tissue oxygenation in the brain and skeletal muscle measured by ...
