Biodiversity of macrophyte communities and associated aquatic organisms in lakes of the Vologda Region (north-western Russia).

Background: This paper provides current data on the biodiversity of boreal lakes of the Vologda Region (north-western Russia), including macrophytes (vascular plants and macroscopic algae) and macrophyte inhabitants (invertebrates and microalgae). The raw data, given in two datasets (Sampling event dataset and an Occurrence dataset) and presented in the form of GBIF-mediated data, were collected from 139 lakes (macrophytes between 2005 and 2021, macrophyte inhabitants between 2014 and 2020). The dataset contains materials on the diversity of vascular plants (Tracheophyta, 3225 occurrences; Bryophyta, 155; Marchantiophyta, 16), macro- and microalgae (Ochrophyta, 546 occurrences; Chlorophyta, 193; Charophyta, 153; Cyanobacteria, 139; Cryptophyta, 86; Myzozoa, 33; Euglenozoa, 27; Rhodophyta, 8; Bigyra, 1) and aquatic invertebrates (Arthropoda, 1408 occurrences; Annelida, 487; Mollusca, 263; Platyhelminthes, 36; Cnidaria, 11).

Stochastic resonance in a proton pumping Complex I of mitochondria membranes.

We make use of the physical mechanism of proton pumping in the so-called Complex I within mitochondria membranes. Our model is based on sequential charge transfer assisted by conformational changes which facilitate the indirect electron-proton coupling. The equations of motion for the proton operators are derived and solved numerically in combination with the phenomenological Langevin equation describing the periodic conformational changes.

[Platelet Metabolism in Clopidogrel Resistant and Sensitive Patients With Ischemic Heart Disease].

Objective: to investigate relationship between activity of platelet nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP) dependent dehydrogenases in patients with ischemic heart disease (IHD) after coronary artery bypass grafting (CABG) and their sensitivity to clopidogrel.

Material And Methods: We studied 51 male patients with chronic IHD before and after CABG. Control group comprised 35 healthy men.

[Characteristics of vitreous structure in rhegmatogenous hyaloid membrane detachment].

Special characteristics of volumetric acoustic digital images of different vitreous and hyaloid membrane changes were studied based on the analysis of results of ultrasound spatial examination of young healthy adults (30 patients) and patients with posterior hyaloid membrane detachment (329 patients). Morphological features of vitreous are presented considering topography and its acoustical structure. Spatial characteristics of planar and volumetric images are determined, special acoustic signs are revealed for normal vitreous and in different changes of posterior hyaloid membrane.

[Damage of macular ganglion cell complex and peripapillary retinal nerve fiber layer in multiple sclerosis].

The aim of this study was to evaluate macular ganglion cell complex (GCC) characteristics and peripapillary retinal nerve fiber layer (RNFL) thickness in patients with multiple sclerosis (MS) and to investigate the associations between these parameters and clinical characteristics of patients for evaluation perspectives of using this method for monitoring of disability and neurodegenerative processes. We examined a total of 113 participants (analysis of 211 eyes), divided into three groups: 1. 48 MS patients (66 eyes) with a history of optic neuritis (ON); 2.
