Arsenic trioxide （ATO）, a component of the traditional Chinese medicine arsenic sublimate, promotes apoptosis and induces leukemic cell differentiation. Combined with all-trans-retinotic acid （ATRA）, ATO has become the first-line induction therapy in treating acute promyelocytic leukemia （APL）. The most common side effects of ATO include hepatotoxicity, gastrointestinal symptoms, water-sodium retention, and nervous system damage. In this report, we present a rare side effect, rhabdomyolysis, in a 68-year-old female APL patient who was treated with ATO. After taking 10 mg ATO daily for 6 days, she presented shortness of breath, myodynia, elevated creatine kinase, and acute renal insufficiency. This report describes the first case of ATO-induced rhabdomyolysis.

Lamb waves are used to detect fouling in food vessels. The propagation of the Lamb waves in plates exhibits many modes and dispersion characteristics, which have great influence on fouling detection. The relative distribution of the in-plane and out-of-plane displacement of the mode across the thickness of the plate will determine the sensitivity of the mode to a particular loading condition. By considering the dispersion and multi-mode characteristics of guided waves, an interdigital polyvi- nylidene fluoride （PVDF） transducer is designed to realize the mode selection of gnided waves, and a single a0 mode is used for guided wave detection. Fouling detection experiments are conducted in the laboratory using epoxy adhesive on a thin plate. Using the interdigital PVDF transducer, three fouled areas are detected. Using one of the time-frequency analysis methods, the waveforms are further processed. This also demonstrates the validity of this method of fouling detection.

The transparent envelope structure has huge energy-saving potential, which is the key point to reduce building energy consumption and improve the thermal building environment. The solar radiation transmitted through the transparent envelope structure(transmitted solar radiation) is reflected, scattered and absorbed by the indoor surface, which has a significant impact on the heat gain of the building. In this paper, firstly, the diffuse radiation received by different depths of various indoor surfaces is measured by experimental tests, and the distribution function of transmitted diffuse solar radiation(TDSR) on the indoor surface is established. Secondly, the diffuse solar radiation received by the indoor and outdoor surfaces in different seasons is continuously monitored;the variation of TDSR with time is analyzed, and the distribution function of TDSR on indoor surface with time is proposed. Finally, based on the temporal and spatial distribution characteristics of diffuse radiation under different weather conditions, the variation of TDSR with the weather is studied, and the distribution function of TDSR on the indoor surface with weather changes is established. The distribution function of the TDSR on the indoor surface under different depths, time and weather conditions obtained in this study can supplement and improve the theory of building heat gain and load, and help accurate simulation of building energy consumption.

The technique of electrocatalytic hydrogen evolution reaction (heR) represents a development trend of clean energy generation and conversion,while the electrode catalysts are bound to be the core unit in the electrochemical heR ***,we demonstrate a bottom-up approach to the construction of three-dimensional (3D) interconnected ternary nanoarchitecture originated from Ti_(3)C_(2)T_(x)MXene,graphitic carbon nitride nanosheets and graphene (MX/CN/RGO) through a convenient co-assembly *** virtue of the 3D porous frameworks with ultrathin walls,large specific surface areas,optimized electronic structures,high electric conductivity,the resulting MX/CN/RGO nanoarchitecture expresses an exceptional heR performance with a low onset potential of only 38 m V,a small Tafel slop of 76 m V dec^(-1) as well as long lifespan,all of which are more competitive than those of the bare Ti_(3)C_(2)T_(x),g-C_(3)N_(4),graphene as well as binary MX/RGO and CN/RGO *** simulations further verify that the ternary MX/CN/RGO nanoarchitecture with ameliorative band structure is able to facilitate the electron transport and meanwhile offer multistage catalytically active sites,thereby guaranteeing rapid heR kinetics during the electrocatalytic process.

The tricarboxylic acid(TCA)cycle identified in 1937 by Hans Adolf Krebs and William Arthur Johnson(also known as the Krebs cycle or citric acid cycle)is a central route for oxidative metabolism to generate cellular energy and intermediates for the biosynthesis of amino acids,lipids,and nucleic acids(Krebs and Johnson 1937).The TCA cycle connects carbohydrate,fat,and protein metabolism and converts these nutrient catabolism-derived acetyl-CoA into carbon dioxide and water,with the production of reduced NAD+(NADH),reduced flavin adenine dinucleotide(FADH2),and guanosine triphosphate(GTP).The generated NADH and FADH2 are,in turn,used by the oxidative phosphorylation pathway to generate energy-rich adenosine triphosphate(ATP)(Chakrabarty and Chandel 2021).
