α-Functionalized α,β-unsaturated aldehydes is an important class of compounds, which are widely used in fine organic synthesis, biology, medicine and pharmacology, chemical industry, and agriculture. Some of the 2-substituted 2-alkenals are found to be the key metabolites in plant and animal cells. Therefore, the development of efficient methods for their synthesis attracts the attention of organic chemists. This review focusses on the recent advances in the synthesis of 2-functionally substituted 2-alkenals. The approaches to the preparation of α-alkyl α,β-unsaturated aldehydes are not included in this review.

Toxoplasmosis induced by Toxoplasma gondii is a well-known health threat, that prompts fatal encephalitis increased with immunocompromised patients, in addition, it can cause chorioretinitis, microcephaly, stillbirth in the fetus and even led to death. Standard therapy uses sulfadiazine and pyrimethamine drugs revealed beneficial results during the acute stage, however, it has severe side effects. UPLC-ESI-MS/MS used to explore C.

Background: Despite the insights into the role of aldehyde dehydrogenase 1 family member A1 (ALDH1A1) in various liver diseases, the expression and its prognostic significance in patients with hepatitis E virus-related acute liver failure (HEV-ALF) remain unclear. This study delved into the assessment of serum exosome-derived ALDH1A1 expression and its prognostic implications for HEV-ALF patients.
Methods: Between January 2018 and December 2023, a total of 226 individuals with acute hepatitis E (AHE) and 210 patients with HEV-ALF were recruited from member units of Chinese Consortium for the Study of Hepatitis E.

Plant cuticular waxes serve as highly responsive adaptations to variable environments. Aliphatic waxes consist of very-long-chain (VLC) compounds produced from 1-alcohol- or alkane-forming pathways. The existing variation in 1-alcohols and alkanes across Arabidopsis accessions revealed that 1-alcohol amounts are negatively correlated with aridity factors, whereas alkanes display the opposite behaviour.

Background: Tubular injury triggered by hyperglycemia is an important pathological characteristic in diabetic nephropathy (DN). Accumulated advanced glycation end products and their precursor methylglyoxal (MGO), contribute to the development of DN. Carnosine has been shown to prevent the development of DN but the underlying mechanism still needs to be studied in depth.
