Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

СТРУКТУРА И ДИНАМИКА НА ФИТОПЛАНКТОНА В ЯЗОВИР „КЪРДЖАЛИ“
Subject of study were the species composition and seasonal dynamics of phytoplankton in “Kardzhali” damlake. The presence of 67 taxa of 7 divisions was established: Cyanoprokaryota (12), Chlorophyta (21), Streptophyta (7), Pyrrhophyta (2), Euglenophyta (

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

The dynamical model describing several stages of interaction between populations of predators and preys in some area is proposed. The transition from one stage to another is determined by the values of the function which has the sense of trophical ...

α‐Synuclein aggregation landscape from phase separation to neurotoxic intermediates
Alpha‐synuclein aggregation in Parkinson's disease involves a complex landscape of transient intermediates, including oligomers, fibrils and liquid–liquid phase separation (LLPS). A view is emerging in which LLPS maturation into solid‐like condensates may contribute to the formation of neurotoxic species.

Orchid bee fauna responds to habitat complexity on a savanna area (Cerrado) in Brazil.
Habitat structure and complexity may broadly affect the diversity and composition of a variety of fauna in terrestrial systems. Here we investigated responses of orchid bee assemblages to habitat complexity, with the aim of assessing complexity as a ...

Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
