Association Study of the M132L Single Nucleotide Polymorphism With Susceptibility to Chronic Wasting Disease in Korean Elk: A Meta-Analysis.

Chronic wasting disease (CWD) is a deleterious brain proteinopathy caused by a pathogenic form of prion protein (PrP), which is converted from a benign form of prion protein (PrP) encoded by the prion protein gene (). In elk, the M132L single nucleotide polymorphism (SNP) of the gene likely plays a pivotal role in susceptibility to CWD. However, the association of the M132L SNP with susceptibility to CWD has not been evaluated in Korean elk to date.

In-depth examination of PrP in Holstein cattle carrying the E211K somatic mutation of the bovine prion protein gene (PRNP).

Prion diseases are transmissible spongiform encephalopathies caused by deleterious prion protein (PrP ) derived from normal prion protein (PrP ), which is encoded by the prion protein gene (PRNP). We performed an in-depth examination to detect PrP by using enzyme immunoassay (EIA), real-time quaking-induced conversion reactions (RT-QuIC) and protein misfolding cyclic amplification (PMCA) in nine brain tissues derived from three Holstein cattle carrying the E211K somatic mutation of the bovine PRNP gene. The EIA, RT-QuIC and PMCA analyses were not able to detect the PrP band in any tested samples.

The complete mitochondrial genome of (Erxleben, 1777), as a model species of Chronic Wasting Disease (CWD).

(Erxleben, 1777) has been used as a model species of Chronic Wasting Disease (CWD). We completed the mitochondrial genome of , susceptible to the CWD. Its length is 16,428 bp, identical to the previous mitochondrial genome of , and 37 genes (13 protein-coding genes, two rRNAs, and 22 tRNAs) were identified.

The first complete mitogenome of (Merriam, 1905).

(Merriam, 1905) is one of the subspecies of elk distributed only in California, USA. We completed the first mitogenome of . Its length is 16,428 bp, which is in middle among 24 available mitogenomes.

Outbreak of African swine fever in South Korea, 2019.

African swine fever, a fatal haemorrhagic disease of swine, was confirmed in domestic pigs for the first time in South Korea in September 2019. The causative virus belonged to the p72 genotype II and had an additional tandem repeat sequence in the intergenic region (IGR) between the I73R and I329L.

Identification of novel haplotypes and interpretation of gene flow of mitochondrial DNA control region of Eurasian otter (Lutra lutra) for the effective conservation.

The number and distribution of Eurasian otters have declined during twentieth century due to human activity and water pollution. The global conservation status of Eurasian otter is presently 'Near Threatened (NT)' and strictly protected by being listed on the international legislation and conventions. A number of studies using the mitochondrial DNA (mtDNA) control region (CR) have been conducted in order to effectively apply conservation and reintroduction programs, especially in Europe.

Dependence of the birefringence of polystyrene film on the stretching conditions.

We investigated the dependence of the birefringence of polystyrene (PS) film with a negative optical birefringence on the stretching conditions. We varied the stretching ratio (SR), stretching speed (SS), and stretching temperature (ST), and measured the inplane birefringence and the N coefficient of the PS film. The inplane birefringence was increased with greater SR and SS but decreased with greater ST.

HELLP syndrome in a pregnant patient with Gitelman syndrome.

Gitelman syndrome is characterized by hypokalemia, metabolic alkalosis, hypocalciuria, and hypomagnesemia. The clinical course of Gitelman syndrome in pregnant women remains unclear, but it is thought to be benign. We report here the first Korean case of atypical eclampsia in a 31-year-old who was diagnosed with Gitelman syndrome incidentally during an antenatal screening test.

Single layer retarder with negative dispersion of birefringence and wide field-of-view.

A single layer retarder possessing negative dispersion (ND) of birefringence as well as wide field-of-view (FOV) was long-term objective in optical science. We synthesized new guest reactive monomers with x-shape and mixed them with the host smectic reactive mesogen. The host-guest molecules formed two dimensionally self-organized nanostructure and showed both the ND of birefringence and wide FOV properties.

Comparison of diagnostic accuracy between CellprepPlus® and ThinPrep® liquid-based preparations in effusion cytology.

Liquid-based cytology (LBC) is being increasingly used for body fluid specimens and has improved diagnostic accuracy when compared to conventional smears. We compared the diagnostic accuracy and cellular morphologic features between CellprepPlus® LBC and ThinPrep® LBC in effusion cytology. One hundred and eighty body fluid specimens, consisting of 119 pleural fluid specimens, 59 peritoneal fluid specimens, and 2 pericardial fluid specimens, were obtained from 166 patients.
