Propolis is a bee product used since ancient times due to its diverse biological applications. We aimed investigate the antioxidant and anti-inflammatory action of Brazilian propolis in THP-1 cells stimulated with 1‐fluoro‐2,4‐dinitrobenzene (DNFB) or lipopolysaccharide (LPS). Cell viability was assessed by resazurin assay, activity evaluated DPPH superoxide dismutase (SOD) 1 2 colorimetric ass...

The introduction of “smart” tracer techniques in recent years has provided new ways to investigate sediment-water interactions and microbial activity stream corridors. In this study, the formulation STIR model (Marion et al., 2008) is extended represent transport transformation Resazurin-Resorufin smart tracers, an object-oriented toolbox, STIR-RST, presented for evaluation calibration. STIR-RS...

Computer-aided drug discovery and development approaches such as virtual screening, molecular docking, and in silico drug property calculations have been utilized in this effort to discover new lead compounds against tuberculosis. The enzyme 7,8-diaminopelargonic acid aminotransferase (BioA) in Mycobacterium tuberculosis (Mtb), primarily involved in the lipid biosynthesis pathway, was chosen as...

There remains an urgent need for rapid diagnostic methods that can evaluate antibiotic resistance for pathogenic bacteria in order to deliver targeted antibiotic treatments. Toward this end, we present a rapid and integrated single-cell biosensing platform, termed dropFAST, for bacterial growth detection and antimicrobial susceptibility assessment. DropFAST utilizes a rapid resazurin-based fluo...

The aim of present study is to synthesize a series of different p-substituted benzyl thiosemicarbazone and evaluate their cytotoxicity as well as their antimycobacterial activity. The chemical structures have been assigned by micro analysis and spectral data (UV-Vis, IR and H NMR). All the compounds have been tested for their in vitro cytotoxic activity against leukaemia cancer cell line K562 a...

A new high throughput antibacterial method employing the dye resazurin as an indicator of bacterial growth was developed to evaluate drug susceptibility by combined measurements of microtitre-plates, colorimetric and haemocytometric assays. The bacterial strains E. coli, B. subtilis, P. aeruginosa and S. aureus (multi-drug resistant strain) were used to evaluate the preliminary screening of pla...

Obvious lack of interfibrillar mitochondria (IFM) sub population in isolated mitochondria attributed to limitations in isolation procedure. In this manuscript, we compared the functional activities of mitochondrial sub-populations namely, IFM and sub-sarcolemmal (SSM) mitochondria obtained from isolated rat heart subjected to different perfusion time namely (minutes) 0.5,5,10,25,60 and 120. Pro...

The current study was conducted to biochemical attributes of Pantja Buck semen. For this purpose six mature healthy bucks were selected from the Goat Unit maintained at Department Livestock Production Management, College Veterinary and Animal Sciences, Pantnagar, Uttarakhand (India). All experimental kept under similar feeding management conditions. Semen collection done early morning by artifi...

An ink, comprising the redox dye resazurin (Rz) and the sacrificial electron donor glycerol, is shown to be capable of the rapid assessment of the photocatalytic activities of self-cleaning films. In the key initial stage of photocatalysis the ink changes from blue to pink. Prolonged irradiation bleaches the ink and eventually mineralizes it. The kinetics of the initial photoinduced color chang...

Our objective was to determine whether low-temperature hydrogen peroxide (H2O2) gas plasma sterilization of porous three-dimensional poly(ϵ-caprolactone) (PCL) constructs significantly inhibits cellular metabolism of canine chondrocytes. Porous cylindrical constructs were fabricated using fused deposition modeling and divided into four sterilization groups. Two groups were sterilized with low-t...
