7%) under the same conditions. The highest occupied molecular orbital and lowest unoccupied molecular orbital levels of the sensitizers were tuned to be well-suited for the Cu(I/II) redox potential and the Fermi level of TiO2. The innovative synthesis of a tricarbazole-based donor moiety in a sensitizer used in combination with a Cu(I/II) redox couple has resulted in relatively high PCEs.To achieve high thermoelectric conversion efficiency in Bi0.4Sb1.6Te3 (BST) alloy is vital for its applications in low-grade energy harvesting. Here, we show that 56% increase in the power factor (PF) (from 16 to 25 μW cm-1 K-2) and 32% reduction of lattice thermal conductivity κL (from 0.56 to 0.38 W m-1 K-1) as well as an approximately four-fold decrease in bipolar-effect contribution κb (from 0.48 to 0.12 W m-1 K-1) can be achieved at 512 K through the incorporation of 0.2 vol % PbSe nanoparticles in the BST matrix. Analyses indicate that the remarkable increase in PF for the composite samples can be mainly attributed to strong electron scattering at the large interface barriers, inhibiting effectively the electron contribution to the total thermopower at elevated temperatures, while the large drop of κL and κb originates from enhanced phonon scattering by PbSe nanoinclusions as well as phase boundaries (among BST and PbSe nanophase) and suppression of electron transport, respectively. As a result, a maximum figure of merit (ZT) of 1.56 (at 400 K) and an average ZT (ZTave) of 1.44 in the temperature range of 300-512 K are reached. Correspondingly, a record projected conversion efficiency η = 11% is achieved at the cold side 300 K and hot side 512 K in the BST-based composite incorporated with 0.2 vol % PbSe nanoinclusions.The cannabinoid (CB) receptors (CB1R and CB2R) represent a promising therapeutic target for several indications such as nociception and obesity. The ligands with nonselectivity can be traced to the high similarity in the binding sites of both cannabinoid receptors. Therefore, the need for selectivity, potency, and G-protein coupling bias has further complicated the design of desired compounds. The bias of currently studied cannabinoid agonists is seldom investigated, and agonists that do exhibit bias are typically nonselective. However, certain long-chain endocannabinoids represent a class of selective and potent CB1R agonists. The binding mode for this class of compounds has remained elusive, limiting the implementation of its binding features to currently studied agonists. Hence, in the present study, the binding poses for these long-chain cannabinoids, along with other interesting ligands, with the receptors have been determined, by using a combination of molecular docking and molecular dynamics (MD) simulations along with molecular mechanics-Poisson-Boltzmann surface area (MM-PBSA) binding free energy calculations. find more The binding poses for the long-chain cannabinoids implicate that a site surrounded by the transmembrane (TM)2, TM7, and extracellular loop (ECL)2 is vital for providing the long-chain ligands with the selectivity for CB1R, especially I267 of CB1R (corresponding to L182 of CB2R). Based on the obtained binding modes, the calculated relative binding free energies and selectivity are all in good agreement with the corresponding experimental data, suggesting that the determined binding poses are reasonable. The computational strategy used in this study may also prove fruitful in applications with other GPCRs or membrane-bound proteins.
Period of elderly age preordains the occurrence of many health issues. People deported during World War II to concentration camps suffered from malnutrition, lack of sleep, physical and mental exhaustion. Recently, the health condition of Holocaust survivors is often complicated as a result of physical punishments and different torture methods as well as mental hardships which they had suffered during deportation. The consequences often have psychosomatic nature thus the survivors are often receivers of health care. The topic of bibliography review is based on the need to objectivize and systematically evaluate subjective health issues of Holocaust survivors in connection with trauma related to the stay in a concentration camp. The aim is to offer a review of effects of the Holocaust on health of different body systems for survivors in concentration camps and Jewish ghettos in the course of World War II.

To map the subjective problems of Holocaust survivors, evidence-based medicine (EBM) method has been urch, these factors have impacted all organ systems, mainly locomotion and cardiovascular ones. The results have shown a more frequent occurrence of osteoporosis, fractures of long bones and corresponding chronical pain of people of Jewish origin who had gone through different forms of torture during World War II. Other present symptoms include gastrointestinal problems, tumors mainly in the area of colorectum and lungs. Moreover, the stay in concentration camps had influence on women's menstrual cycle.

The studies of Holocaust effects are an example of the influence of an extreme mental and physical burden on the body condition of the survivors' health. The results of the studies have shown a wide range of the effects also in mental and social areas.

This study aimed to analyze the complications of planned home births treated at healthcare facilities in the Czech Republic.

This prospective cohort observational study is based on analysis of women hospitalized with complications related to planned home deliveries in the Czech Republic between 2016 and 2017. The data were collected using an online form made accessible to the directors of all maternity hospitals in the Czech Republic. The results were statistically evaluated.

We identified 45 complications during planned home deliveries. Complications occurred most often among women living in largely populated cities with higher levels of education. Overall, 40% of patients did not receive routine antenatal care, and 38% of women gave birth after the 41st week of pregnancy. In 60% of cases, no professionals attended the birth. Hospital transfer frequencies were 42% after delivery, 36% at third-stage labour, 11% first-stage labour, 9% second-stage labour, and 2% before delivery. We recorded four neonatal deaths and one severe newborn morbidity.
