Influence of Zeta Potential on the Amount of Bilirubin Oxidase Oriented for Direct Electron Transfer on Carbon Electrodes

Electrochemistry
Bilirubin oxidase (BOD) is a widely used enzyme for biofuel cell cathodes. When suitably oriented, BOD can transfer electrons directly to electrodes. The BOD variant used herein orients favorably on negatively charged surfaces.

Genomic analysis uncovers laccase-coding genes and biosynthetic gene clusters encoding antimicrobial compounds in laccase-producing Acinetobacter baumannii

Scientific Reports, 2022
Laccases are multicopper oxidase family enzymes that can oxidize various substrates. In this study, we isolated laccase-producing Acinetobacter spp. from the environment, and one isolate of laccase-producing Acinetobacter baumannii, designated NI-65, was

Different behaviour of the N-terminal and C-terminal fragment of proatrial natriuretic factor in plasma of healthy subjects as well as of patients with cirrhosis [PDF]

, 1990
N-terminal (atrial natriuretic factor (ANF) 1-98) and C-terminal (ANF 99-126) fragments of proatrial natriuretic factor (NTA and CTA, respectively) were determined in plasma of healthy subjects adopting different postures and in patients with cirrhosis ...

Population pharmacokinetic/pharmacodynamic modelling to evaluate favipiravir in combination with lopinavir–ritonavir in patients with COVID‐19

British Journal of Clinical Pharmacology, EarlyView.
Aims The repurposed use of favipiravir in COVID‐19 has been reported to have limited clinical efficacy, yet it has been widely used in some countries. Favipiravir causes mutagenesis in RNA viruses, and it is currently unknown whether it may have a measurable effect on the virus in humans.

Nutritional Potential, Phytochemical Content, In Vivo Antioxidant, and Antanemic Potential of Musa paradisiaca Flower

Food Chemistry International, EarlyView.
After collecting Musa paradisiaca leaves, some were dried and others were used to produce aqueous extracts. The extracts and powders were characterized and then administered to rats made anaemic by PHZ. After 14 days of administration of the two samples, the rats were euthanized and it was observed that after 9 days of treatment, the aqueous extract ...

Determination of conjugated and total bilirubin in serum of neonates, with use of bilirubin oxidase.

Clinical Chemistry, 1987
Abstract A new, simple, and rapid assay for conjugated bilirubin that does not require serum-matrix standards was developed by using the enzyme bilirubin oxidase (EC 1.3.3.5). This procedure can also be modified to measure total bilirubin.
