Aqueous Solution Enhanced Room Temperature Phosphorescence through Coordination-Induced Structural Rigidity.

Achieving aqueous solution enhanced room temperature phosphorescence (RTP) is critical for the applications of RTP materials in solution phase, but which faces a great challenge. Herein, for the first time, a strategy of coordination-induced structural rigidity is proposed to achieve enhanced quantum efficiency of aluminum/scandium-doped phosphorescent microcubes (Al/Sc-PMCs) in aqueous solution. The Al/Sc-PMCs in a dry state exhibit a nearly invisible blue RTP.

Inorganic salt recrystallization strategy for achieving ultralong room temperature phosphorescence through structural confinement and aluminized reconstruction.

Achieving highly efficient and stable room temperature phosphorescence (RTP) with ultralong lifetime is critical for the multi-purpose applications of phosphorescent materials. In this work, we propose an inorganic salt heating recrystallization strategy to simultaneously improve the lifetime, quantum efficiency, and stability of phosphorescent scandium/leucine microspheres (Sc/Leu-MSs). Inorganic salt-treated Sc/Leu-MSs are obtained by simply heating and drying inorganic salt solution containing Sc/Leu-MSs, which can achieve a maximum lifetime increase of 4.

First Report of Leaf Spot Disease Caused by Alternaria brassicae on Camptotheca acuminata in Sichuan, China.

Camptotheca acuminata (C. acuminata), is belongs to a monotypic genus endemic to southwestern China and listed as the first class national protected plant in China in 1999 (Wen, et al. 2020).

Does Dexmedetomidine Reduce the Risk of Atrial Fibrillation and Stroke After Adult Cardiac Surgery? A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Background: Postoperative atrial fibrillation is a common consequence of cardiac sur-gery with increased stroke complications and mortality. Although dexmedetomidine is thought to prevent postoperative atrial fibrillation and stroke because of its sympa-tholytic and anti-inflammatory properties, data from different studies show the effect of dexmedetomidine on postoperative atrial fibrillation and stroke uncertain in adult patients with cardiac surgery.

Methods: A database including EMBASE, PubMed, and Cochrane CENTRAL was searched for randomized controlled trials comparing dexmedetomidine with placebo or other anesthetic drugs in adult cardiac surgery.

First Report Davidia involucrate Baill Leaf Blight Caused by Nigrospora oryzae in Sichuan, China.

Davidia involucrata Baill. (D. involucrate), also known as dove tree, is listed as the first class national protected plant in China and the only extant member of the Davidiaceae family (Fu & Jin 1992).

Clinical Validation of a Myeloid Next-Generation Sequencing Panel for Single-Nucleotide Variants, Insertions/Deletions, and Fusion Genes.

Myeloid neoplasms are a heterogeneous group of neoplasms including acute myeloid leukemia (AML), myeloproliferative neoplasms, myelodysplastic syndrome, and myeloproliferative neoplasms/myelodysplastic syndrome. Genetic abnormalities are used as diagnostic, prognostic, and predictive biomarkers in patients with these diseases. Herein, we describe the clinical validation of the Oncomine Myeloid Research (OMR) next-generation sequencing panel that interrogates for 40 genes and 29 fusion genes commonly seen in myeloid neoplasms.

An immunosensor based on magnetic relaxation switch and polystyrene microparticle-induced immune multivalency enrichment system for the detection of Pantoea stewartii subsp. Stewartii.

A rapid, sensitive, and simple immunosensor has been developed for the detection of Pantoea stewartii subsp. Stewartii (Pss). This immunosensor combines magnetic relaxation switch (MRS) assay with polystyrene microparticle-induced immune multivalency enrichment system.

tert-Butyl 3-amino-2-methyl-6,7-dihydro-2H-pyrazolo[4,3-c]pyridine-5(4H)-carboxyl-ate.

In the mol-ecule of the title compound, C(12)H(20)N(4)O(2), the dihydro-piperidine ring assumes a half-chair conformation. In the crystal, cllassical N-H⋯O and N-H⋯N inter-molecular hydrogen bonds link mol-ecules into double chains along the a axis.

trans-Bis(5-carb-oxy-2-methyl-1H-imidazole-4-carboxyl-ato-κN,O)copper(II).

In the title compound, [Cu(C(6)H(5)N(2)O(4))(2)], the copper(II) atom lies on an inversion centre and is in an N(2)O(2) four-coordinate environment with a nearly regular square-planar geometry. An extended network of intra-molecular O-H⋯O and inter-molecular N-H⋯O and C-H⋯O hydrogen bonds stabil-izes the crystal structure.

Diaqua-bis(2-methyl-1H-imidazol-3-ium-4,5-dicarboxyl-ato-κO,O')magnesium.

The title compound, [Mg(C(6)H(5)N(2)O(4))(2)(H(2)O)(2)], was prepared by reaction of Mg(NO(3))(2) and 2-methyl-1H-imidazole-4,5-dicarboxylic acid under hydro-thermal conditions. The Mg(II) atom lies on an inversion centre and displays a distorted octa-hedral coordination geometry. An extended three-dimensional network of inter-molecular O-H⋯O and N-H⋯O hydrogen bonds stabilizes the crystal structure.
