he intracellular behaviors of radiometabolites played crucial roles in the elimination rates and the routes of the radioactivity from the kidney.Recent advances in flexible materials and wearable electronics offer a noninvasive, high-fidelity recording of biopotentials for portable healthcare, disease diagnosis, and machine interfaces. Current device-manufacturing methods, however, still heavily rely on the conventional cleanroom microfabrication that requires expensive, time-consuming, and complicated processes. Here, we introduce an additive nanomanufacturing technology that explores a contactless direct printing of aerosol nanomaterials and polymers to fabricate stretchable sensors and multilayered wearable electronics. Computational and experimental studies prove the mechanical flexibility and reliability of soft electronics, considering direct mounting to the deformable human skin with a curvilinear surface. The dry, skin-conformal graphene biosensor, without the use of conductive gels and aggressive tapes, offers an enhanced biopotential recording on the skin and multiple uses (over ten times) with consistent measurement of electromyograms. The combination of soft bioelectronics and deep learning algorithm allows classifying six classes of muscle activities with an accuracy of over 97%, which enables wireless, real-time, continuous control of external machines such as a robotic hand and a robotic arm. Collectively, the comprehensive study of nanomaterials, flexible mechanics, system integration, and machine learning shows the potential of the printed bioelectronics for portable, smart, and persistent human-machine interfaces.As essential structural molecules for plant plasma membranes, phytosterols are key intermediates for the synthesis of many downstream specialized metabolites of pharmaceutical or agricultural significance, such as brassinosteroids and withanolides. Saccharomyces cerevisiae has been widely used as an alternative producer for plant secondary metabolites. Establishment of heterologous sterol pathways in yeast, however, has been challenging due to either low efficiency or structural diversity, likely a result of crosstalk between the heterologous phytosterol and the endogenous ergosterol biosynthesis. For example, in this study, we engineered campesterol production in yeast using plant enzymes; although we were able to enhance the titer of campesterol to ∼40 mg/L by upregulating the mevalonate pathway, no conversion to downstream products was detected upon the introduction of downstream plant enzymes. Further investigations uncovered two interesting observations about sterol engineering in yeast. First, many heterologous sterols tend to be efficiently and intensively esterified in yeast, which drastically impedes the function of downstream enzymes. Second, yeast can overcome the growth deficiency caused by altered sterol metabolism through repeated culture. By employing metabolic engineering, strain evolution, fermentation engineering, and pathway reconstitution, we were able to reconstruct the multienzyme pathways for the synthesis of a set of phytosterols campesterol (∼7 mg/L), β-sitosterol (∼2 mg/L), 22-hydroxycampesterol (∼1 mg/L), and 22-hydroxycampest-4-en-3-one (∼4 mg/L). This work identified and addressed some of the technical bottlenecks in phytosterol-derived pathway reconstitution in the baker's yeast and opens up opportunities for efficient bioproduction and metabolic pathway elucidation of this group of phytochemicals.The long-term shortage of freshwater resources has drawn increasing research attention for water purification and collection. This work reports a facile method to prepare Janus fabrics with asymmetric wettability for on-demand oil/water separation and hydrophobic/hydrophilic patterned fabrics for efficient fog harvesting. Here, the superhydrophobic fabric was prepared by in situ polymerization of polydivinylbenzene (PDVB) on cotton fabric. By regulating the polymerization time, the PDVB polymer content was changed, thereby achieving the regulation of the surface structure and wettability of the prepared fabric. Meanwhile, the superhydrophobic fabric exhibited excellent self-cleaning and antifouling performance, mechanical abrasion and chemical resistance, and environmental durability. Moreover, the photocatalytic degradation properties of PDVB were utilized to prepare the Janus fabric with asymmetric wettability. Water droplets could spontaneously penetrate from the hydrophobic side to the hydrophilic side, wensed collection of water.Regional citrate anticoagulation (RCA) is currently the recommended anticoagulation modality for continuous renal replacement therapy. Indeed, compared with systemic heparinization, RCA is associated with a lower risk of bleeding, a longer circuit lifespan and a decrease nursing workload. However, RCA requires a strict protocol to be followed, as it might be associated with potentially severe complications, such as citrate accumulation. Citrate accumulation is rare and usually associated with specific situations severe circulatory shock, liver failure and mitochondrial dysfunction. According to centers' expertise, these situations might represent contra-indications to RCA. This review presents RCA, its mode of action, associated risks and proposes an algorithm for patients' selection.Chemotherapy induced neutropenic fever requires a hospitalization in 20-30 % of cases and is then associated with a mortality above 10 %. selleck products Hospitalized patients require strict isolation, which sometimes results in a substantial physical and psychological burden. Granulocyte-colony stimulating factors (G-CSF) are established in the primary and secondary prevention of chemotherapy-induced neutropenia. However, their role as adjunctive therapy in patients with neutropenic fever is less clear. This review resumes current best evidence in this area and discusses current recommendations.Atrial fibrillation (AF) is the most common cardiac arrhythmia in the general population and in patients with sepsis hospitalized in intensive care. The indication for long-term anticoagulation is based on expert recommendations that take into account data from the general population and thus recommend therapeutic anticoagulation for AF longer than 48 hours. However, a majority of new onset AF in intensive care seem to last less than 48 hours and additional risk factors such as the type of sepsis, the drugs administered as well as the presence of a central venous catheters, are involved. Moreover, the increased of minor and major hemorrhage renders it difficult to apply the usual recommendations. In this literature review, we will focus on the various risk factors, prognosis, and indication of long-term anticoagulation in the new onset AF in this population.
