Synergistic influence of iodine and hydrogen peroxide towards the degradation of harmful algal bloom of Microcystis aeruginosa.

Cyanobacterial blooming due to the influence of temperature and increased nutrients in ponds/lakes aided by the runoff from agricultural lands, is a serious environmental issue. The presence of cyanotoxins in water may poison the health of aquatic organisms, animals, and humans. In this study, we focus on chemical assisted degradation of Microcystis aeruginosa- an alga that is of special relevance owing to its consistent blooming, especially in tropical regions.

Bioconjugation of Meldrum's acid activated furan: A detergent compatible assay for protein quantitation.

A simple yet efficient assay for the quantitation of proteins ranging from plasma proteins to purified proteins from whole cell lysate, based on the bioconjugation reaction between protein and Meldrum's acid Activated Furan (MAF) is described. This easy to use, sensitive method is based on the conjugation of amine functionalities present on the protein with MAF to form the corresponding Donor Acceptor Stenhouse Adducts (DASAs) with characteristic absorption in the visible region. The reaction is rapid as well as reproducible and shows a proportionate increase in color change over a broad range of protein concentration.

Performance & clinical utility of oropharyngeal versus nasopharyngeal swabs in COVID-19.

Background & Objectives: The oropharyngeal (OP) and nasopharyngeal (NP) swab samples are the most recommended clinical specimens for detecting SARS-CoV-2 in an individual through the quantitative real-time reverse-transcriptase-polymerase chain reaction (rRT-PCR) method. The primary objective of this study was to compare the performance of NP and OP swabs for the diagnosis of COVID-19 among 2250 concomitant samples (1125 NP + 1125 OP) using rRT-PCR test.

Methods: This study was conducted at a tertiary care hospital in southern India.

Biomimetic Total Synthesis of (+)-Nocardioazine B and Analogs.

Nocardioazines A and B are prenylated, bioactive pyrroloindoline natural products, isolated from , with a desymmetrized -d-Trp-d-Trp DKP core. Based on our deeper biosynthetic understanding, a biomimetic total synthesis of (+)-nocardioazine B is accomplished in merely seven steps and 23.2% overall yield.

Indole-3-butyric acid mediated growth and biochemical enhancement in three Selenastracean green microalgae under limited supply of nitrogen source.

The effects of Indole-3-butyric acid (IBA) supplementation in combination with nitrogen limitation on the biomass, biochemical and fatty acid composition of three selenastracean microalgae were studied. In the algae tested, nitrogen deficiency alone resulted in lower biomass output, whereas supplementation with 0.075 mM IBA resulted in increased biomass production on Selenastrum capricornutum (679 mg L), Ankistrodesmus falcatus (521 mg L) and Kirchneriella obesa (361 mg L) than their respective controls.
