Thymic Hematoma Found in a Wild Eurasian Otter (Lutra lutra).

Thymic hematomas are uncommon in animals, and the few reported cases are all in dogs. In May 2019, we necropsied a wild Eurasian otter (Lutra lutra) in Junju, Republic of Korea, and found a thymic hematoma without any signs of trauma or hemorrhage in other organs, except for a hemothorax. This study describes the macroscopic and microscopic examinations of a thymic hematoma in an Eurasian otter.

Linear Micro-patterned Drug Eluting Balloon (LMDEB) for Enhanced Endovascular Drug Delivery.

In-stent restenosis (ISR) often occurs after applying drug eluting stents to the blood vessels suffering from atherosclerosis or thrombosis. For treatment of ISR, drug eluting balloons (DEB) have been developed to deliver anti-proliferative drugs to the lesions with ISR. However, there are still limitations of DEB such as low drug delivery efficiency and drug loss to blood flow.

Maysin and Its Flavonoid Derivative from Centipedegrass Attenuates Amyloid Plaques by Inducting Humoral Immune Response with Th2 Skewed Cytokine Response in the Tg (APPswe, PS1dE9) Alzheimer's Mouse Model.

Alzheimer's disease (AD) is a slow, progressive neurodegenerative disease and the most common type of dementia in the elderly. The etiology of AD and its underlying mechanism are still not clear. In a previous study, we found that an ethyl acetate extract of Centipedegrass (CG) (i.

Mycobacterium bovis infection in a wild sow (Sus scrofa): first case in Korea.

Mycobacterium (M.) bovis causes tuberculosis and has a broad host range, including humans, livestock, and wild animals. M.

Protective effect of centipedegrass against Aβ oligomerization and Aβ-mediated cell death in PC12 cells.

Context: Alzheimer's disease (AD) is a neurodegenerative disorder characterized by the abnormal accumulation of β-amyloid (Aβ). Multiple Aβ-aggregated species have been identified, and neurotoxicity appears to be correlated with the amount of non-fibrillar oligomers. Potent inhibitors of Aβ oligomer formation or Aβ-induced cell toxicity have emerged as attractive means of therapeutic intervention.

Centipede grass exerts anti-adipogenic activity through inhibition of C/EBPβ, C/EBPα, and PPARγ expression and the AKT signaling pathway in 3T3-L1 adipocytes.

Background: Centipede grass (CG) originates from China and South America and is reported to contain several C-glycosyl flavones and phenolic constituents, including maysin and luteolin derivatives. This study aimed to investigate, for the first time, the antiobesity activity of CG and its potential molecular mechanism in 3T3-L1 cells.

Methods: To study the effect of CG on adipogenesis, differentiating 3T3-L1 cells were treated every day with CG at various concentrations (0-100 μg/ml) for six days.

Determination of enantiomeric compositions of DOPA by tandem mass spectrometry using the kinetic method with fixed ligands.

A fixed ligand (FL) version of the kinetic method was applied to rapid, simple, and accurate chiral analysis of DOPA, which is an important drug used for treatment of Parkinson's disease. Singly charged clusters containing the transition metal ion Cu(II), pyridyl ligands which serve as a fixed ligand, some amino acid as a reference, and the analyte DOPA were generated by electrospray ionization. The cluster ion of interest was mass-selected, and the kinetics of its competitive unimolecular dissociations was investigated in an ion trap mass spectrometer.

Enantioselective resolution of thyroxine hormone by high-performance liquid chromatography utilizing a highly fluorescent chiral tagging reagent.

A highly fluorescent chiral tagging reagent, 4-(3-isothiocyanatopyrrolidin-1-yl)-7-(N,N-dimethylaminosulfonyl-2,1,3-benzoxadiazole, [R(-)-DBD-PyNCS], was employed to develop an indirect resolution method for efficient separation of thyroxine enantiomers,D-T(4) and L-T(4). The reaction of R(-)-DBD-PyNCS with the thyroxine enantiomers proceeds effectively at 40 degrees C for 20 min in the presence of basic medium to produce the corresponding pair of diastereomers. No racemization occurs during the tagging reaction under the optimized conditions.
