A dynamic HPLC study of C(70) chlorination led to the discovery, isolation, characterization, and development of the efficient preparatory procedures for two previously unknown soluble chlorofullerenes C(70)Cl(8) and C(70)Cl(6) and for insoluble [C(70)Cl(8)](n). A novel synthesis of 99% pure C(70)Cl(10) with a nearly quantitative yield was also developed. The first stability study of C(70)Cl(10,8,6) in solution showed that these compounds are very light-sensitive.

Innovative separation of melittin from bee venom using micro-free-flow electrophoresis: An experimental and theoretical study.
Anal Chim Acta

Background: Bee venom consists of more than 50 % melittin (MLT), which has anti-cancer, anti-inflammatory, and antimicrobial properties. Bee venom also contains toxic components such as phospholipase A2 (PLA2) and hyaluronidase (HYA), which cause allergic reactions, so the toxic components must be removed to use MLT. In previous studies, analytical methods were used to separate MLT.

Although vinegar is a product obtained by a well-known bioprocess from a technical point of view, the complex microbiota responsible for its production and their involvement in the organoleptic profiles are not clear yet. In this work, three acetification profiles in submerged culture using both synthetic and raw materials from Andalusia (Spain) were characterized by metagenomic (16S rRNA amplicon sequencing) and metabolomic tools (stir-bar sorptive extraction with thermo-desorption coupled to gas chromatography-mass spectrometry (SBSE-TD-GC-MS) and high-performance liquid chromatography (HPLC)). A total of 29 phyla, 208 families, and many more genera were identified, comprising bacteria and archaea as well as 75 metabolites, including minor volatile compounds, amino acids, biogenic amines, and other nitrogenous compounds.

The cerebellum, a key target of ethanol's toxic effects, is associated with ataxia following alcohol consumption. However, the impact of ethanol on Purkinje cell (PC) mitochondria remains unclear. To investigate how ethanol administration affects mitochondrial dynamics in cerebellar Purkinje cells, we employed a transgenic mouse model expressing mitochondria-targeted yellow fluorescent protein in Purkinje cells (PC-mito-eYFP).

Antimicrobial resistance is a major global concern and economic threat, necessitating a reliable monitoring approach to understand its frequency and spread via the environment. Hospital wastewater serves as a critical reservoir for antimicrobial-resistant organisms; however, its role in resistance gene distribution and dissemination remains poorly understood. This study integrates metagenomic and metatranscriptomic analyses, elucidating the dynamics of antimicrobial resistance in hospital wastewater.
