Effects of cold water immersion versus active recovery on oxidative stress, redox gene expression and mitochondrial adaptations after strength training

open access: yesExperimental Physiology, EarlyView.
Abstract We compared the acute and chronic effects of postexercise cold water immersion (CWI) and active recovery (ACT) on oxidative stress, redox‐related gene expression, mitochondrial adaptations and muscle oxidative capacity. In a crossover study, nine males completed strength sessions, followed by either 10 min CWI or ACT.

Redox-Annulations of Cyclic Amines with 2‑(2-Oxoethyl)malonates

open access: yes, 2018
Amines such as 1,2,3,4-tetrahydroisoquinoline undergo redox-neutral annulations with 2-(2-oxoethyl)­malonates in the presence of catalytic amounts of benzoic acid.

Oocyte–cumulus cell interaction: a key factor in early embryo development

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2265-2278, October 2026.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

Ligações hidrogênio fortes em ácidos dicarboxílicos e diaminas aromáticas

open access: yesQuímica Nova, 2000
A very short-strong hydrogen bond (20kcal/mol) is found in the monoanion of certain dicarboxylic acids derived from maleic and dialkylmalonic acids. Certain aromatic diamines that are known as proton sponge have exceptionally high basicity (pKa) and are ...

Efficient Palladium-Catalyzed Cross-Coupling of β-Chloroalkylidene/arylidene Malonates Using Microwave Chemistry

open access: yes, 2016
A general method for the synthesis of β-aryl/alkylarylidene malonates is reported. The key step involves the coupling of an arylboronic acid to a β-chloroalkyl/arylidene malonate, in the presence of K2CO3 and 1 mol % of the air-stable palladium catalyst (

Metal‐Catalyzed Transformations of Carbon Dioxide Toward the Production of Commodity Chemicals

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 17, 1 September 2026.
This perspective highlights how transition‐metal catalysis can enable the synthesis of economically attractive CO2‐derived commodity chemicals. By transforming waste CO2 into acrylic acid, cyclic carbonates, and other valuable products, these strategies provide a practical route for simultaneous CO2 sequestration and valorization, helping to align ...
