Simulation of blood flows in the pulmonary artery provides some insight into certain diseases by examining the relationship between some continuum metrics, e.g. the wall shear stress acting on the vascular endothelium, which responds to flow-induced mechanical forces by releasing vasodilators/constrictors. In [?kheyfets2015patient], V. Kheyfets studies numerically a patient-specific pulmonary circulation to show that decreasing wall shear stress is correlated with increasing pulmonary vascular impedance. In this paper, we develop a scalable parallel algorithm based on domain decomposition methods to investigate an unsteady model with patient specific pulsatile waveforms as the inlet boundary condition...

Rheumatoid arthritis (RA) is a chronic inflammatory disorder characterized by infiltration of the joint synovium by activated inflammatory cells. CD4+ T cells form a large proportion of the inflammatory cells invading the synovial tissue, and are involved in the RA pathological process. In general, CD4+ T cells differentiate into various T helper (Th) cell subsets and acquire the functional characterization to respond to specific pathogens, and also mediated some autoimmune disorders such as RA. Because the differentiation of Th cell subsets is determined by the expression of specific transcription factors in response to cytokine environment, these transcription factors is considered to have a role in pathology of RA...

Anderson Abel de Souza Machado, Werner Kloas, Christiane Zarfl, Stefan Hempel, Matthias C Rillig
Microplastics (plastics < 5 mm, including nanoplastics which are < 0.1 μm) originate from the fragmentation of large plastic litter or from direct environmental emission. Their potential impacts in terrestrial ecosystems remain largely unexplored despite numerous reported effects on marine organisms. Most plastics arriving in the oceans were produced, used, and often disposed on land. Hence, it is within terrestrial systems that microplastics might first interact with biota eliciting ecologically relevant impacts...

Climate warming is substantially shifting the leaf phenological events of plants, and thereby impacting on their individual fitness and also on the structure and functioning of ecosystems. Previous studies have largely focused on the climate impact on spring phenology, and to date the processes underlying leaf senescence and their associated environmental drivers remain poorly understood. In this study, experiments with temperature gradients imposed during the summer and autumn were conducted on saplings of European beech to explore the temperature responses of leaf senescence...

Question The medical investigation of school beginners is one of the essential tasks of the child and youth services of the health authorities. While in all federal states in Germany, the examination of all school beginners is legally clearly stipulated, the situation for "lateral entry", that is, children of school age, who are moving from a foreign country to a local German community and attending school there, is not clearly regulated in the respective school laws. This article presents the experiences of the lateral entry investigations in Frankfurt am Main...

Goals Despite numerous reported deficits and an increasingly tense working environment in German hospitals, employees themselves often assess their job satisfaction as being high to very high. Hence, the board of directors does not have important arguments for sustainable improvement of working conditions. This discrepancy between working conditions and subjective satisfaction was the motivation for this work. Methods Data were acquired via an attitude survey at the University Hospital for Children and Adolescents Leipzig, with employees sub-divided into medical, nursing and administrative/technical staff...

The meromictic Lake Cadagno is characterized by a compact chemocline with high concentrations of anoxygenic phototrophic purple sulfur bacteria (PSB) and green sulfur bacteria (GSB). The co-occurrence of phylogenetically distant bacterial groups such as PSB and GSB in the same ecological niche, makes the chemocline of Lake Cadagno an ideal system for studying the conditions and consequences of coexistence of photosynthetic bacteria populations. In this study, we applied flow cytometry (FCM) as a fast tool to identify metabolic changes due to the production and consumption of inclusion bodies such as sulfur globules (SGBs), and follow population dynamics of closely related anoxygenic photosynthetic sulfur bacteria in their natural environment...

OBJECTIVES: To evaluate operator pelvic radiation exposure during percutaneous coronary procedures. BACKGROUND: During percutaneous coronary procedures, the operator's pelvic region is close to the x-ray source and is probably exposed to more radiation than the operator's thorax. However, no data are available on the pelvic radiation exposure of interventional cardiologists. METHODS: The RADIANT study (NCT01974453) is a prospective, single-center, observational study evaluating operator radiation exposure during percutaneous coronary procedures using electronic dosimeters placed at thorax level...

Due to highly recalcitrant and toxicological nature of pyridine, the conventional anaerobic bioprocess is often limited by low removal rate and poor process stability. In this study, an electricity-assisted anaerobic system was developed in order to enhance biodegradation of pyridine from wastewater. The results showed that the performance and stability of the anaerobic reactor was remarkably improved for pyridine biodegradation with the applied direct current of 0.3 mA, where the efficiencies of pyridine and total organic carbon removal as well as NH4+-N formation were as high as 100...

Arsenic (As) remediation in contaminated water using nanoparticles is promising. However, the fate and transport of As associated with nano-adsorbents in natural environment is poorly understood. To investigate the fate of adsorbed As on nano-TiO2 in changed redox condition from oxic to anoxic, we added the As(V)-TiO2 suspension in groundwater to an autoclaved soil column which inoculated a sulfate-reducing bacterium, Desulfovibrio vulgaris DP4. The dissolved As(V) in effluent increased to 798 μg/L for the biotic column and to 1510 μg/L for the abiotic control, and dissolved As(III) was observed only in biotic column...

Numerous studies have documented the negative effects of ozone (O3) on tree species in growing season, however, little is done in non-growing season. Three evergreen tree species, Phoebe bournei (Hemsl.) Yang (P. bournei), Machilus pauhoi Kanehira (M. pauhoi) and Taxus chinensis (Pilger) Rehd (T. chinensis), were exposed to non-filtered air, 100 nmol mol-1 O3 air (E1) and 150 nmol mol-1 O3 air (E2) in open-top chambers in subtropical China. In the entire period of experiment, O3 fumigation decreased net photosynthesis rate (Pn) through stomatal limitation during the transition period from growing to non-growing season (TGN), and through non-stomatal limitation during the period of non-growing season (NGS) in all species tested...
