One‐Pot Ruthenium‐Catalyzed Synthesis of Benzyl/Allyl‐Halide Substituted (dihydro)naphthalenes via Radical Benzannulation

ChemistryEurope, EarlyView.
A one‐pot protocol to synthesize reactive benzyl‐ and allyl‐halide‐substituted (dihydro)naphthalenes from 2,3‐aryl‐1,3‐butadiene substrates and halogenated alkanes has been developed, using [Cp*RuCl(PPh3)2] as the catalyst. Mechanistic studies revealed an atom transfer radical addition and radical benzannulation sequence, followed by HCl elimination ...

Microbial trimethylamine metabolism in marine environments [PDF]

, 2019
Trimethylamine (TMA) is common in marine environments. Although the presence of this compound in the oceans has been known for a long time, unlike the mammalian gastrointestinal tract, where TMA metabolism by microorganisms has been studied intensely ...

Data‐Driven Design of Scalable Perovskite Film Fabrication via Machine Learning–Guided Processing

Carbon Energy, EarlyView.
Considering complex process parameters and poor reproducibility in perovskite thin film fabrication, this study uses machine learning to analyze and predict high‐dimensional process variables. The Random Forest model, identified as the most effective, can effectively analyze and rapidly predict optimal process parameters from extensive data.

Effect of Epigallocatechin‐3‐Gallate on Depression‐Related Cytokines in Thalassemia Patients: Molecular and Cellular Evaluation

Journal of Clinical Laboratory Analysis, EarlyView.
This study investigates the effects of Epigallocatechin‐3‐Gallate (EGCG), a potent anti‐inflammatory polyphenol isolated from Winged Marigold, on cytokine expression linked to depression in β‐thalassemia patients. EGCG demonstrated dose‐dependent suppression of key inflammatory cytokines (IL‐6, IL‐1β, TNF‐α, IFN‐γ) at both gene and protein levels ...

Vegetable Oil‐Based Materials for Drug Delivery Systems and Wound Dressings

Macromolecular Bioscience, EarlyView.
Renewable resources like vegetable oils are increasingly explored for biomaterial production in biomedical applications. Their monoglycerides and triglycerides inherently possess functions or can be chemically modified to introduce functional groups suitable for polymerization, yielding biomaterials with desirable properties such as flexibility ...
