Yak1 is a member of dual-specificity Tyr phosphorylation-regulated kinases (DYRKs) that are evolutionarily conserved. The downstream targets of Yak1 and their functions are largely unknown. Here, a homologous protein AtYAK1 was identified in Arabidopsis thaliana and the phosphoprotein profiles of the wild type and an atyak1 mutant were compared on two-dimensional gel following Pro-Q Diamond pho...

The paper characterizes sclerosing mucoepidermoid carcinoma with eosinophilia, a rare thyroid tumor, including histological and immunohistochemical features. The authors give their observation of a 26-year-old patient. The immunohistochemical findings (positive p63 and TTF-1 tumor cell nuclear staining) show the dual nature of a tumor arising from the cells of the ultimobranchial body and folli...

If we had a case with angiographic peri-stent contrast staining(PSS)s after the first-generation sirolimus-eluting stent, we need a further observation using coronary imaging modalities to evaluate the risk of very late stent thrombosis due to PSSs and to continue or to resume the dual antiplatelet therapy if necessary.

background and objective: tuberculosis is still a major health problem, involving about 1/3 of the world´s population. diagnosis is difficult when we only use ziehl-neelson staining. many cases may be missed. a more rapid and sensitive diagnostic method is necessary. pcr may be helpful. the aim of this study was to compare pcr, zieh-neelsen staining and histopathologic findings in diagnosis of ...

OBJECTIVE Glucosamine is widely used to improve the symptoms and to delay the structural progression of osteoarthritis. However, its efficacy in osteoarthritis has been controversial and its underlying mechanism of action remains unclear. The aim of this study was to investigate the effects of glucosamine and the underlying mechanisms in human chondrocytes. METHODS Chondrocytes from normal hu...

Objective To preliminarily evaluate technical feasibility of a dual-echo ultrashort echo time (UTE) subtraction MR imaging by using concurrent dephasing and excitation (CODE) sequence for visualization of iron-oxide enhancement in focal inflammatory pulmonary lesions. Materials and Methods A UTE pulmonary MR imaging before and after the injection of clinically usable superparamagnetic iron-ox...

OBJECTIVE The recent advent of flow cytometry (FCM), coupled with fluorescent dyes, has been successfully applied to assess mitochondrial function. The aim of this study was to investigate the feasibility and clinical significance of detecting sperm mitochondrial function and to evaluate sperm mitochondrial function by using Rhodamine 123/propidium (Rh123/PI) dual fluorescent staining and FCM i...

OBJECTIVE Enzymatic degradation of the extracellular matrix is known to be powerful regulator of atherosclerosis. However, little is known about the enzymatic regulation of heparan sulfate proteoglycans (HSPGs) during the formation and progression of atherosclerotic plaques. METHODS AND RESULTS Swine were rendered diabetic through streptozotocin injection and hyperlipidemic through a high fat...

Among different staining methods used to demonstrate the nuclear abnormalities, Feulgen is one of the most reliable method. Feulgen staining is specific, sensitive method for evaluating the DNA damages.It has been shown that using non-DNA specific stains for monitoring the nuclear anomalies lead to false-positive or false-negative results. From self-experience, immersing the stained slides in h...
