Logistic analysis of delayed reporting of emergency blood potassium and comparison of improved outcomes.

Potassium testing is an essential test in emergency medicine. Turnaround time (TAT) is the time between specimen receipt by the laboratory and the release of the test report. A brief in-laboratory TAT increases emergency department effectiveness.

Efficient evaluation of photodynamic therapy on tumor based on deep learning.

Photodynamic therapy (PDT) is a non-invasive treatment method for treating tumors. Under laser irradiation, photosensitizers in tumor tissues generate biotoxic reactive oxygen, which can kill tumor cells. The traditional live/dead staining method of evaluating the cell mortality caused by PDT mainly depends on manual counting, which is time-consuming and relies on dye quality.

Application of the FMEA Method in Improving the Quality Management of Emergency Complete Blood Count Testing.

Objective: Failure mode and effects analysis (FMEA) was used to identify factors that contribute to quality management deficiencies in laboratory testing of emergency complete blood count (CBC).

Methods: Improvements included instrument updates, personnel training, and laboratory information system optimization. We used operational data from January 2021 (control group) and January 2022 (FMEA group) to compare the risk priority number (RPN) of FMEA, emergency CBC laboratory turnaround time (TAT), error report rate, and specimen failure rate.

Six phenanthrenes from the roots of Rolfe. and their biological activities.

A new phenanthrene compound, 7-(4-hydroxybenzyl)-8-methoxy-9,10- dihydrophenanthrene-2,5-diol (), along with five known compounds (Coelonin, , Shancidin, and ) were isolated from the roots of Rolfe. (CFR). Their structures were identified using various spectroscopic methods.

Improvement of the activity and SO tolerance of Sb-modified Mn/PG catalysts for NH-SCR at a low temperature.

A series of MnM/palygorskite (PG) (M = La, W, Mo, Sb, Mg) catalysts was prepared by the wetness co-impregnation method for low-temperature selective catalytic reduction (SCR) of NO with NH. Conversion efficiency followed the order Sb > Mo > La > W > Mg. A combination of various physico-chemical techniques was used to investigate the influence of Sb-modified Mn/PG catalysts.

Rapid Screening for EGFR Inhibitor in Rhei Radix et Rhizoma by HTRF Assay Coupled with HPLC Peak Fractionation.

In this paper, an HPLC peak fractionation approach combined with homogeneous time-resolved fluorescence analysis is proposed for screening epidermal growth factor receptor inhibitors from Rhei Radix et Rhizoma. With this approach, the amount of sample used for a single HPLC run is sufficient for performing a multiple assay due to the miniaturization ability of the homogeneous time-resolved fluorescence technology. This allows for improving the stability and repeatability of the activity assay for each fraction.

Germination Response of Four Alien Congeneric Amaranthus Species to Environmental Factors.

Seed germination is the key step for successful establishment, growth and further expansion of population especially for alien plants with annual life cycle. Traits like better adaptability and germination response were thought to be associated with plant invasion. However, there are not enough empirical studies correlating adaptation to environmental factors with germination response of alien invasive plants.

Small RNA and degradome sequencing reveals microRNAs and their targets involved in tomato pedicel abscission.

We constructed small RNA and degradome sequencing libraries to identify miRNAs and targets involved in tomato pedicel abscission, and confirmed their roles via quantitative real-time PCR. MicroRNAs (miRNAs) are endogenous small RNAs which play crucial negatively regulatory roles at both the transcriptional and post-transcriptional levels in plants; however, limited knowledge is available on the expression profiles of miRNAs and their target genes during tomato pedicel abscission. Taking advantage of small RNA (sRNA) and degradome sequencing technology, a total of 56 known and 11 novel candidate miRNAs targeting 223 mRNA genes were confirmed during pedicel abscission.

Purification and partial characterization of a new antitumor protein from Tegillarca granosa.

A new protein, coded as D2-3, was obtained from the marine organism Tegillarca granosa L. by anion exchange and hydrophobic chromatography. The purity of D2-3 was over 99.

A new in vitro anti-tumor polypeptide isolated from Arca inflata.

A new in vitro anti-tumor polypeptide, coded as J2-C3, was isolated from Arca inflata Reeve and purified by diethyl-aminoethanol (DEAE)-sepharose Fast Flow anion exchange and phenyl sepharose CL-4B hydrophobic chromatography. J2-C3 was identified to be a homogeneous compound by native polyacrylamide gel electrophoresis (Native-PAGE). The purity of J2-C3 was over 99% in reversed phase-high performance liquid chromatography (RP-HPLC).

Enhancement of vindoline and vinblastine production in suspension-cultured cells of Catharanthus roseus by artemisinic acid elicitation.

Elicitation is an important strategy to improve production of secondary metabolites in vitro. Artemisinic acid was studied as a novel elicitor to enhance the yield of terpenoid indole alkaloids in the present paper. Our results demonstrated that the concentrations of vindoline and vinblastine were increased by sixfold and twofold, respectively, compared to those of the control group after treatment with artemisinic acid.

Rice hull/MnFe2O4 composite: preparation, characterization and its rapid microwave-assisted COD removal for organic wastewater.

Adsorbent/ferrite composites can adsorb and degrade organics in the organic wastewater treatment. In this study, a rice hull/MnFe(2)O(4) composite (RHM) was prepared via calcination under nitrogen atmosphere and was used to treat organic wastewater with the assistance of microwave radiation. Rice hull was pyrolysed to a porous substrate that consisted of silica and activated carbon under high temperature.
