Reversible transformations of sulfamethoxazole and its submoieties by manganese-oxidizing bacteria and biogenic manganese oxides in the presence of humic substances.

Manganese-oxidizing bacteria (MnOB) and biogenic manganese oxides (BioMnOx) play key roles in the breakdown of organic matter (including pollutants) in water and soil environments. The degradation of some organic compounds (such as sulfonamides selected in this study) by BioMnOx in the presence of active MnOB is poorly understood. Thus far, it has been shown that the transformation of sulfonamides by either BioMnOx or MnOB (but thus far not studied in a binary system) can be modulated using naturally occurring redox mediators, such as humic substances, leading to the formation of coupling products of unknown stability.

Changes in glucose-related parameters according to LDL-cholesterol concentration ranges in non-diabetic patients.

The study focused on the changes in C-peptide, glycemia, insulin concentration, and insulin resistance according to LDL-cholesterol concentration ranges. The metabolic profile of individuals in the Czech Republic (n = 1840) was classified by quartiles of LDL-cholesterol into four groups with the following ranges: 0.46-2.

Ir(I)-Bi(III) Donor-Acceptor Adducts Stabilized by Dispersion Interactions between the Metal Pincer Ligands and Their Possible Self-Assembly Forming Molecular 1D Semiconductors.

Structure, stability, and electronic properties of the bimetallic {[Ir(terpy)(Me)]-[BiNNN]} monomeric, oligomeric, and polymeric structures ( = 1-3 and ∞; terpy = terpyridine; Me = methyl; BiNNN = bismuth triamide) and their derivatives (designated as (Bi·Ir) structures) were studied theoretically by DFT cluster and periodic calculations. Stable Bi·Ir adducts (monomers) were formed with short Bi-Ir bonds (<2.7 Å) and Gibbs free binding energies larger than 20 kcal/mol for all systems.

Opinions of citizens of the Czech Republic on the role of nurses in primary care during the COVID-19 pandemic.

Introduction And Objective: In spite of the general current decrease in COVID-19 incidence, the epidemiological situation on the territory of the Czech Republic is still unfavourable. Nurses play an essential role in the fight against this disease.

Material And Methods: A non-standardized questionnaire was used to discover the expectations regarding nursing care provided during the COVID-19 pandemic.

Comparison between EWGSOP1 and EWGSOP2 criteria and modelling of diagnostic algorithm for sarcopenic obesity in over 70 years old patients.

Purpose: Sarcopenic obesity (SO) as a new diagnostic entity defined by presence of obesity in combination with sarcopenia represents serious health condition negatively affecting quality of life in old age. Despite the rapidly increasing incidence of SO associated with demographic aging, clear diagnostic criteria for SO have not yet been established. We describe here the applicability of the EWGSOP2 and EWGSOP1 diagnostic criteria in identifying sarcopenia and SO and the development of a refinement algorithm for SO detection.

Incidence of spontaneous abortions and congenital anomalies in the vicinity of a uranium processing plant.

Objectives: The exposure of embryos or foetuses to ionising radiation can cause serious detriments to health. Thus, an enhanced incidence of spontaneous abortions and congenital anomalies might be expected in the vicinity of a uranium processing plant. We analysed the situation in the vicinity of MAPE Mydlovary, a facility about 20 km from České Budějovice, South Bohemia, Czech Republic, which was in operation from 1963 to 1992.

Selected Risk Factors of Falls in Hospitalized Patients: A Case-Control Study.

Theory: Patients falls have a multifactorial character and typically have multiple causalities.

Goal: The goal of the study was to identify risk factors for falls of hospitalized patients.

Methodology: This was a case-control study.

Participation of adult patients in healthcare.

In this study, the question of health literacy in adult patient population in the Czech Republic is explored in the context of healthcare, particularly in the South Bohemian Region. The study is based on the analysis of qualitative data which were collected during the first half of 2016. The study included 34 adult participants at the age range between 18 and 64 years.

Pt···H Nonclassical Interaction in Water-Dissolved Pt(II) Complexes: Coaction of Electronic Effects with Solvent-Assisted Stabilization.

The structure of the hydration shell of cisplatin, cis-[Pt(NH3)2Cl2], and its aquated derivatives cis-[Pt(NH3)2Cl(H2O)](+), cis-[Pt(NH3)2OH(H2O)](+), and cis-[Pt(NH3)2(H2O)2](2+) were studied by a number of density functional molecular dynamics (DFT-MD) simulations (from 30 to 250 ps) in which Pt(II) complexes were immersed in a periodic box with 72 explicit water molecules. Furthermore, Pt(II) complex-water binding energy curves and full DFT optimizations of clusters derived from the lowest potential energy DFT-MD frames offered a deeper insight into the structure of the first hydration shell and electronic changes connected with the formation of a nonclassical Pt···H-O-H (Pt···Hw) hydrogen bond (inverse hydration). The probability of a Pt···Hw interaction decreases with increasing charge of the platinum complex due to disadvantageous electrostatics.
