A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

One-step thermochemical activation of waste wood for micropollutant adsorption: Optimisation via design of experiments

Case Studies in Chemical and Environmental Engineering
The increasing generation of waste wood (WW) and the demand for activated carbon (AC) in wastewater treatment highlight the need for sustainable alternatives. WW was converted into AC via one-step thermochemical activation using carbon dioxide, steam, or

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Controlling sub-nanometer pore-entrance size enables kinetic separation of Li+, Na+, and K+ in capacitive deionization

Carbon Trends
Efficient recovery of lithium and potassium from saline resources is vital for energy storage and global food security. We present a novel capacitive deionization (CDI) approach employing carbon molecular sieve (CMS) electrodes with precisely tuned sub ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Antioxidant properties of cashew leaves' extracts before and after treatment with activated carbon used in cosmetics [PDF]

, 2011
Natural ingredients such as cashew leaves extract could be an attractive candidate in cosmetic formulation. However, the plant extracts are normally dark brown and greenish color that might spoil the appearance of the products if they are added in ...
