The characterization of elemental cycles has a rich history in biogeochemistry. Well known examples include the global carbon cycle, or the cycles of the 'grand nutrients' nitrogen, phosphorus, and sulfur. More recently, efforts have increased to better understand the natural cycling of technology critical elements (TCEs), i.e. elements with a high supply risk and economic importance in the EU. On the other hand, tools such as material-flow analysis (MFA) can help to understand how substances and goods are transported and accumulated in man-made technological systems ('anthroposphere')...

The ability of Broadband Acoustic Resonance Dissolution Spectroscopy (BARDS) to assess the wettability of powder blends is investigated. BARDS is a novel analytical technology developed based on the change in acoustic phenomenon observed when material is added into a solvent under resonance. Addition of solid material to the solvent results in the introduction of gas (air) into the solvent, changing the compressibility of the solvent system and reducing the velocity of sound in the solvent. As a material is wetted and dissolved, the gas is released from the solvent and resonance frequency is altered...

Analysing the genomic data of pathogens with the help of next-generation sequencing (NGS) is an increasingly important part of disease outbreak investigations and helps guide responses. While this technology has already been successfully employed to elucidate and control disease outbreaks, wider implementation of NGS also depends on its cost-effectiveness. COMPARE - short for 'Collaborative Management Platform for detection and Analyses of (Re-) emerging and foodborne outbreaks' - is a major project, funded by the European Union, to develop a global platform for sharing and analysing NGS data and thereby improve the rapid identification, containment and mitigation of emerging infectious diseases and foodborne outbreaks...

Simulation validity depends on how well sampling distributions used reflect real-patient characteristics, such as drug adherence, disease progression, and pharmacologic handling in the body. We challenge the current use of growth charts from nondisease-specific pediatrics in simulations for drug development. Complementary use of data from clinical trials and the real-world is expected to achieve a more realistic representation of clinical outcomes for decisions in drug development, regulatory approval, and health technology assessment...

Human induced pluripotent stem cells (hiPSC) hold great promise in diagnostic and therapeutic applications. However, translation of hiPSC technology depends upon a means of assessing hiPSC quality that is quantitative, high-throughput, and can decipher malignant teratocarcinoma clones from normal cell lines. These attributes are lacking in current approaches such as detection of cell surface makers, RNA profiling, and/or teratoma formation assays. The latter remains the gold standard for assessing clone quality in hiPSCs, but is expensive, time-consuming, and incompatible with high-throughput platforms...

In recent years, the ecology, security, and sustainable development of modern mines have become the theme of coal mine development worldwide. However, spontaneous combustion of coal under conditions of oxygen supply and automatic exothermic heating during coal mining lead to coalfield fires. Coal spontaneous combustion (CSC) causes huge economic losses and casualties, with the toxic and harmful gases produced during coal combustion not only polluting the working environment, but also causing great damage to the ecological environment...

Brain shift during tumor resection compromises the spatial validity of registered preoperative imaging data that is critical to image-guided procedures. One current clinical solution to mitigate the effects is to reimage using intraoperative magnetic resonance (iMR) imaging. Although iMR has demonstrated benefits in accounting for preoperative-to-intraoperative tissue changes, its cost and encumbrance have limited its widespread adoption. While iMR will likely continue to be employed for challenging cases, a cost-effective model-based brain shift compensation strategy is desirable as a complementary technology for standard resections...

The term optical coherence tomography angiography (OCTA) comprises different OCT-based technologies which all allow noninvasive assessment of retinal perfusion, based on moving red blood cells. The main areas where OCTA is currently used are investigation of perfusion and vascular structure of the macular retina (e.g., in macular degenerations and diabetic macular diseases) and the disk and peripapillary retina (in glaucoma and other optic disk diseases). The current editorial provides a brief overview on the potential of OCTA and its use to measure perfusion in the peripapillary retina in glaucoma...

REVIEW

AKI and CKD are important clinical problems because they affect many patients and the associated diagnostic and treatment paradigms are imperfect. Ultrasound is a cost-effective, noninvasive, and simple imaging modality that offers a multitude of means to improve the diagnosis, monitoring, and treatment of both AKI and CKD, especially considering recent advances in this technique. Ultrasound alone can attenuate AKI and prevent CKD by stimulating the splenic cholinergic anti-inflammatory pathway. Additionally, microbubble contrast agents are improving the sensitivity and specificity of ultrasound for diagnosing kidney disease, especially when these agents are conjugated to ligand-specific mAbs or peptides, which make the dynamic assessment of disease progression and response to treatment possible...

The present study was aimed to avoid pharmacokinetic transitions of itraconazole (ITZ) evoked by high-fat meal intake by employing a self-micellizing solid dispersion (SMSD) approach. The dissolution behavior of SMSD/ITZ was assessed in simulated gastric fluid (SGF) and simulated intestinal fluid (SIF). To evaluate the food effect on the oral absorption profile of ITZ, a pharmacokinetic study was conducted on orally-dosed ITZ samples in fasted and high-fat meal-fed rats. Crystalline ITZ showed a 9.0-fold higher dissolution amount of ITZ in fed-state SGF (FeSSGF) than in fasted-state SGF (FaSSGF), whereas there was no significant difference in the dissolution amount of ITZ in SMSD/ITZ between FeSSGF and FaSSGF...
