Novel Long Noncoding RNAs, and , Serve as Potential Diagnostic and Prognostic Biomarkers or Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is one of the most fatal human malignancies worldwide. In this research, we aimed to identify long noncoding RNAs (lncRNAs) as biomarkers for HCC diagnosis and prognosis. lncRNA expression profiles were obtained from Gene Expression Omnibus and The Cancer Genome Atlas databases.

Isolation of From COVID-19 Swab Kits.

To investigate and characterize the putative contaminant isolated from throat and anal swab samples of patients from three fever epidemic clusters, which were not COVID-19 related, in Shenzhen, China, during COVID-19 pandemic. Bacteria were cultured from throat ( = 28) and anal ( = 3) swab samples from 28 fever adolescent patients. The isolated bacterial strains were identified using matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF/MS) and the VITEK2 automated identification system.

[Analysis of risk factors of acute respiratory distress syndrome secondary to severe multiple trauma].

Objective: To explore the risk factors of acute respiratory distress syndrome (ARDS) secondary to severe multiple trauma and the role of clinical guidance.

Methods: The clinical data of 115 patients with severe multiple trauma admitted to the trauma center of Zhenjiang First People's Hospital from December 2017 to September 2020 were retrospectively analyzed. According to whether ARDS occurred within 1 week of the disease course, the patients were divided into ARDS group and non-ARDS group.

Crystallization Kinetics of Concurrent Liquid-Metastable and Metastable-Stable Transitions, and Ostwald's Step Rule.

Experimental measurements of colloidal crystallization in a wide range of volume fractions of charged particles were performed to investigate the liquid-metastable-stable transition process. To fit the obtained experimental data, we developed a theoretical model to formulate the kinetics of the concurrent liquid-metastable and metastable-stable transitions. This model is well-supported by our observations.

A study on independently using static and dynamic light scattering methods to determine the coagulation rate.

Absolute coagulation rate constants were determined by independently, instead of simultaneously, using static and dynamic light scattering with the requested optical factors calculated by T-matrix method. The aggregating suspensions of latex particles with diameters of 500, 700, and 900 nm, that are all beyond validity limit of the traditional Rayleigh-Debye-Gans approximation, were adopted. The results from independent static and dynamic light scattering measurements were compared with those by simultaneously using static and dynamic light scattering; and three of them show good consistency.
