Efficiency and effectiveness of physical and chemical mutagens and their combination in inducing chlorophyll mutations in M2 generation of Lablab [Lablab purpureus (l.) Sweet var. Typicus] [PDF]

open access: yesElectronic Journal of Plant Breeding, 2010
A comparative study of the frequency and spectrum of chlorophyll mutations induced by gamma rays (150, 200, 250, 300 and350 Gy), sodium azide (0.5, 1.0, 1.5 and 2.0 mM) and combination treatments of gamma rays and sodium azide (100 Gy + 1.5mM, 150 Gy + 1.

An Injection‐Molded Modified Silicone Rubber for Cancer‐on‐Chip Applications

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This study describes the characterization and application of an injection‐molded functionalized PDMS fluidic insert for the commercially available Micronit system. Modified PDMS can accommodate cell culture and is able to covalently bind proteins for long‐lasting coatings under flow‐conditions.

Flow Analysis in Pathological Microvascular Models by Ultrasound Localization Microscopy

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a new platform combining ultrasound localization microscopy with biomimetic gelatin phantoms to analyze flow dynamics in small vessels with narrowing or obstructions. Using microbubble tracking, the method enables high‐resolution velocity mapping in 100–500 µm channels, revealing flow changes in pathological microvascular conditions

Electrochemical Chemo‐ and Regioselective Heterofunctionalization of Tropones via C(sp2)H Derivatization

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Simple and selective. The electrochemical heterofunctionalization of activated tropones is achieved using readily available inorganic salts. A theoretical model, based on cyclic voltammetry and quantum chemistry calculations, predicts both reactivity trends and site selectivity.

The content of metals in metallothioneins of the bivalve mollusk Unio tumidus depen­ding on different in situ and in vitro exposures

open access: yesБіологічні студії, 2019
Metallothioneins are low-molecular-weight proteins involved in homeostasis and detoxification of the transition metals. The bivalve mollusks are known to be the most effective filter feeding aquatic organisms that provide the accumulation of toxic metals
