[Influence of Pre-treatment Lymphocyte/Monocyte Ratio and Neutrophil/Lymphocyte Ratio on the Prognosis of Patients with Extranodal NK/T-Cell Lymphoma].

Objective: To explore the influence of lymphocyte-to-monocyte ratio (LMR) and neutrophil-to-lymphocyte ratio (NLR) on the prognosis of patients with extranodal NK/T cell lymphoma (ENKTL).

Methods: The clinical data of 203 patients with ENKTL admitted to the First Affiliated Hospital of Zhengzhou University from January 2011 to January 2020 were retrospectively analyzed. The ROC curve determined the limit values of LMR and NLR; Categorical variables were compared using a chi-square test, expressed as frequency and percentage (,%).

[Investigation of postoperative complications in children after dental therapy under general anesthesia].

Objective: This study aimed to evaluate the postoperative complications undergoing dental general anesthesia in children and analyze the prevalence and related factors.

Methods: This prospective study involved 292 systematically healthy children (36 to 71 months old) who received extensive dental treatment under general anesthesia. Data about patients' histories, characteristics, dental and anesthesia procedure were collected.

Interaction between 16M and small ubiquitin-related modifier 1 and E2 conjugating enzyme 9 in mouse RAW264.7 macrophages.

is an intracellular pathogen that invades a host and settles in its immune cells; however, the mechanism of its intracellular survival is unclear. Modification of small ubiquitin-related modifier (SUMO) occurs in many cellular activities. E2 conjugating enzyme 9 (Ubc9) is the only reported ubiquitin-conjugating enzyme that links the SUMO molecule with a target protein.

Rapid Visual Detection of Getah Virus Using a Loop-Mediated Isothermal Amplification Method.

Getah virus (GETV) is a mosquito-borne alphavirus that is considered to be an emerging pathogen. To date, reverse transcription loop-mediated isothermal amplification (RT-LAMP) has not been used to detect GETV. Therefore, we describe a novel, fast, and sensitive LAMP method to detect GETV.

Development of a TaqMan probe-based quantitative reverse transcription PCR assay for detection of Getah virus RNA.

Getah virus (GETV), a mosquito-borne virus that mainly infects horses and pigs, has emerged and spread in China. We developed a highly specific and reproducible TaqMan probe-based quantitative reverse transcription PCR (RT-qPCR) assay targeting the non-structural protein 1 of GETV, whose detection limit is 25.5 copies/µL, which is 100-fold higher than that of conventional RT-PCR.

Gene locations may contribute to predicting gene regulatory relationships.

We propose that locations of genes on chromosomes can contribute to the prediction of gene regulatory relationships. We constructed a time-based gene regulatory network of zebrafish cardiogenesis on the basis of a spatio-temporal neighborhood method. Through the network, specific regulatory pathways and order of gene expression during zebrafish cardiogenesis were obtained.

Outbreak of severe pseudorabies virus infection in pig-offal-fed farmed mink in Liaoning Province, China.

An outbreak of severe pseudorabies virus (PRV) infection in farmed mink occurred in northern China in late 2014, causing significant economic losses in the local fur industry. Here, we report the first case of a PRV outbreak in mink in northeastern China, caused by feeding farmed mink with raw pork or organs contaminated by PRV. Mink infected with virulent PRV exhibited diarrhea, neurologic signs, and higher mortality, which can be misdiagnosed as highly pathogenic mink enteritis virus (MEV), canine distemper virus (CDV), and food poisoning.

Penicimenolides A-F, Resorcylic Acid Lactones from Penicillium sp., isolated from the Rhizosphere Soil of Panax notoginseng.

Five new 12-membered resorcylic acid lactone derivatives, penicimenolides A-E (1-5), one new ring-opened resorcylic acid lactone derivative penicimenolide F (6), and six known biogenetically related derivatives (7-12) were isolated from the culture broth of a strain of Penicillium sp. (NO. SYP-F-7919), a fungus obtained from the rhizosphere soil of Panax notoginseng collected from the Yunnan province of China.

Evaluation of Suitable Internal Control Genes for RT-qPCR in Yak Mammary Tissue during the Lactation Cycle.

The yak is primarily found throughout the Tibetan high plateau and the surrounding mountainous area of south central Asia; among its others attributes, its milk is very important for the local population. A key concern in the field of yak research is the better understanding of which genes control the production and composition of milk. The most accurate and sensitive method for gene expression analysis is quantitative reverse transcription polymerase chain reaction (RT-qPCR).

Poly[bis-[μ(2)-(dimethyl-aza-nium-yl)methyl-enediphospho-nato]magnesium].

The title compound, [Mg(C(3)H(10)NO(6)P(2))(2)](n), synthesized by a hydro-thermal method, adopts a one-dimensional polymeric chain structure and is isotypic with the previously reported Cd complex based on the ligand N,N-dimethyl-amino-methane-1,1-diphospho-nic acid (H(4)L). The asymmetric unit contains one half Mg(2+) ion and one H(3)L(-) anion. The unique Mg(2+) ion lies on an inversion center and is octa-hedrally coordinated by O atoms from six phospho-nate groups of four different H(3)L(-) anions.

Molecular mutations associated with the in vitro passage of virulent porcine reproductive and respiratory syndrome virus.

Mutants of a highly pathogenic, porcine reproductive, and respiratory syndrome virus (PRRSV), JXA1 strain, were prepared by continuous in vitro passage. Genomic sequence comparisons were made between mutants obtained at different passages and the parental strain JXA1. The mutant strain obtained at passage 80 contained a 12 nucleotide insertion and 108 nucleotide mutations that resulted in 45 amino acid changes.
