Modification of mutagenic efficiency of sodium azide.

open access: yesCYTOLOGIA, 1983
Effect of soaking in oxygenated water, gibberelic acid on azide mutagenesis and DMSO used as carrier of sodium azide were investigated in barley. Presoaking for 8-16 hours in oxygenated water enhanced mutagenic efficiency of sodium azide. In treatment when mutagen was dissolved in 0.5 to 0.75% of DMSO it appeared to be more efficient.

Identification of microtubule-associated proteins in the centrosome, spindle, and kinetochore of the early Drosophila embryo. [PDF]

open access: yes, 1989
We have developed affinity chromatography methods for the isolation of microtubule-associated proteins (MAPs) from soluble cytoplasmic extracts and have used them to analyze the cytoskeleton of the early Drosophila embryo.

Development of f‐ELISA Sensors with Ultrahigh Sensitivity for On‐Site Colorimetric Detection of Fentanyl and Norfentanyl

open access: yesAdvanced Sensor Research, EarlyView.
A foam‐based ELISA (f‐ELISA) platform was developed using chemically modified melamine foam to enable rapid, ultrasensitive, and selective colorimetric detection of fentanyl and norfentanyl. Abstract Rapid and accurate detection of fentanyl in unknown products and aqueous samples can find the unexpected existence of the toxic chemical and assist law ...

A Polyoxometalate—Carbon Nanotube Enhanced Electrochemical Sensor for Aptamer‐Based Diagnostics

open access: yesAdvanced Sensor Research, EarlyView.
The high electroactive surface area of multi‐walled carbon nanotubes decorated with aptamer‐functionalized polyoxovanadate units enables a ≈1000‐fold increase in peak current response for a model diclofenac detection in aqueous solution compared to unmodified platinum microelectrodes.

Monoclonal antibodies to the cells of a regenerating limb [PDF]

open access: yes, 1985
Monoclonal antibodies were raised against differentiated cells, and blastemal cells from regenerating limbs of adult newts (Notophthalmus viridescens) and screened for specific staining by immunocytochemistry.

Hemp Proteins Conjugated with Green Tea Polyphenol Extract Form De Novo Plant‐Sourced Emulsifiers Suitable for Nanodelivery Systems Bearing Lipophilic Psychopharmaceuticals

open access: yesAdvanced Therapeutics, EarlyView.
Green tea polyphenols, conjugated either covalently or non‐covalently to hemp protein, comprise an excellent stabilizing matrix for oxidatively‐sensitive small molecules. These nanoemulsions are highly stable to a variety of chemical and physical stressors, protecting the small molecule while allowing for easy uptake across cell membranes and rapid ...

Nanopolystyrene (nanoPS) and Sodium Azide (NaN3) Toxicity in Danio rerio: Behavioural and Morphological Evaluation

open access: yesMicroplastics
Nano- (NPs) and microplastics (MPs) are ubiquitous and raising concerns about their toxicity. A popular model for studying acute toxicity is Danio rerio. This study investigated the acute toxicity in FET test of polystyrene nanoparticles (500 nm, nanoPS)
