Nuclear factor erythroid 2-related factor 2 (Nrf2) plays a pivotal role in cellular defense against oxidative stress damage after ischemic stroke. In the present study, we examined the time-dependent change of in vivo optical imaging of oxidative stress after stroke with Keap1-dependent oxidative stress detector (OKD) mice. OKD mice were subjected to transient middle cerebral artery occlusion (tMCAO) for 45 min, and in vivo optical signals were detected during the pre-operative period, 12 h, 1 d, 3 d, and 7 d after tMCAO...

Here, we report the design and use of G protein-coupled receptor-based biosensors to monitor ligand-mediated conformational changes in receptors in intact cells. These biosensors use bioluminescence resonance energy transfer with Renilla luciferase (RlucII) as an energy donor, placed at the distal end of the receptor C-tail, and the small fluorescent molecule FlAsH as an energy acceptor, its binding site inserted at different positions throughout the intracellular loops and C-terminal tail of the angiotensin II type I receptor...

PURPOSE: To evaluate and compare changes in axial elongation, over a 14-month period, in subjects who discontinued and then resumed ortho-k lens wear with those who continued to wear their lenses or spectacles following a 2-year myopia control study. METHOD: This single masked, prospective study recruited subjects who had just completed a 2-year myopia control study. Ortho-k subjects were classified as Group OKc, in which subjects continued ortho-k lens wear for the duration of the study; or Group OKd in which subjects discontinued lens wear for seven months and wore single-vision spectacles (Phase I) and then resumed ortho-k lens wear for another seven months (Phase II)...

The aim of this study was to investigate whether a Keap1-dependent oxidative stress detector-luciferase (OKD-LUC) mouse model would be useful for the visualization of oxidative stress induced by experimental periodontitis. A ligature was placed around the mandibular first molars for seven days to induce periodontitis. Luciferase activity was measured with an intraperitoneal injection of d-luciferin on days 0, 1, and 7. The luciferase activity in the periodontitis group was significantly greater than that in the control group at seven days...

Crocetin, the aglycone of crocin, is a carotenoid found in fruits of gardenia (Gardeina jasminoides Ellis) and saffron (Crocus sativus L.). We investigated the protective effects of crocetin against ultraviolet-A (UV-A)-induced skin damage and explored the underlying mechanism. Human skin-derived fibroblasts cells (NB1-RGB) were damaged by exposure to UV-A irradiation (10J/cm(2)). Crocetin protected these cells against cell death and reduced the production of reactive oxygen species induced by UV-A irradiation...

Increased levels of hypo-galactosylated immunoglobulin (Ig)A1 (HG-IgA1) in IgA nephropathy (IgAN) have been detected using a Helix aspersa agglutinin lectin enzyme-linked immunosorbent assay (ELISA). In this study, we developed monoclonal antibodies to evaluate the HG-IgA1 in IgA nephropathy, aiming to gain a more consistent and reproducible assay. As an analogue to the HG-IgA1 hinge region, a 19 mer synthetic peptide with five GalNAc (sHGP) residues at positions 4, 7, 9, 11 and 15 [VPST(GalNAc)PPT(GalNAc)PS(GalNAc)PS(GalNAc)TPPT (GalNAc)PSPS-NH2] was synthesized...

Oxidative stress plays a critical role in mediating tissue injury and neuron death during ischemia-reperfusion injury (IRI). The Keap1-Nrf2 defense pathway serves as a master regulator of endogenous antioxidant defense, and Nrf2 has been attracting attention as a target for the treatment of IRI. In this study, we evaluated Nrf2 expression in IRI using OKD (Keap1-dependent oxidative stress detector) mice and investigated the neuroprotective ability of an Nrf2 activator. We demonstrated temporal changes in Nrf2 expression in the same mice with luciferase assays and an Nrf2 activity time course using Western blotting...

Diagnosis of the exact grade of oral epithelial dysplasia is difficult, and interobserver variations in grading are common. The aim of this study was to investigate the expression patterns of cytokeratins (CKs) in dysplastic oral epithelia, to identify useful double immunostaining diagnostic markers. Immunoexpression of CK13, CK14, CK17, and Ki-67 were investigated in 21 normal epithelial specimens and 146 epithelial dysplasia specimens. In epithelial dysplasia specimens, orthokeratotic dysplasia (OKD) was identified using CK10 immunostaining...

BACKGROUND: Podocin is a key protein involved in the pathogenesis of steroid-resistant nephrotic syndrome and/or focal segmental glomerulosclerosis (FSGS) and is characterized by a high rate of early recurrence after renal transplantation (RTx) in children and adults. MATERIAL AND METHODS: We studied 206 RTx adult recipients: 187 with a diagnosis of glomerular nephropathy, GN (biopsy-proven in 149, clinical in 38), plus 19 with unknown diagnosis as original kidney disease (OKD), the NPHS2 gene polymorphism, G755A, and correlated with the presence of early recurrence of OKD within the first year (proteinuria over 1 g/day and graft-biopsy proven)...

We propose a new method for a supervised online estimation of probabilistic discriminative models for classification tasks. The method estimates the class distributions from a stream of data in the form of Gaussian mixture models (GMMs). The reconstructive updates of the distributions are based on the recently proposed online kernel density estimator (oKDE). We maintain the number of components in the model low by compressing the GMMs from time to time. We propose a new cost function that measures loss of interclass discrimination during compression, thus guiding the compression toward simpler models that still retain discriminative properties...

AIMS: We investigated a group of oral mucosal lesions with characteristic hyperorthokeratotic foci, which we termed orthokeratotic dysplasia (OKD), to determine if it could be identified as a distinct histopathological entity. METHODS AND RESULTS: We screened 282 surgical specimens from 200 patients with oral leucoplakia-type squamous cell carcinoma (SCC) or carcinoma in situ (CIS). OKD was defined as an oral mucosal lesional focus in which hyperorthokeratosis was predominant in the presence of the granular cell layer...

OBJECTIVES: A precancerous condition is a lesion that, if left untreated, leads to cancer or can be induced to become malignant. In the oral region, leukoplakia is a lesion that has been regarded as precancerous. In cases of oral carcinoma, we have frequently noticed that a type of leukoplakia histologically demonstrating hyper-orthokeratosis and mild atypia (ortho-keratotic dysplasia; OKD) is often associated with carcinoma, either synchronously or metachronously. Therefore, we consider OKD-type leukoplakia to be a true precancerous lesion...

Comparative studies between Portuguese (T and HF) and Japanese (S10, T4, C14-5 and OKD-1) isolates of the pinewood nematode Bursaphelenchus xylophilus have been made in order to provide information to better understand the possible origin of the Portuguese isolates, recently introduced in the European Union. The main comparative aspects investigated were pathogenicity (seedling mortality ratio), sexual compatibility, and DNA sequences of the rDNA region. Four-year-old Japanese black pine (Pinus thunbergii) seedlings were used as host plants for pathogenicity tests...

BACKGROUND: Immunoglobulin A nephropathy (IgAN) is characterized by an aberrant structure of O-glycans in the IgA1 hinge region. Recently, under-galactosylated IgA1 has been found to be increased in Caucasian IgAN patients. Thus, we examined this in Japanese IgAN patients. METHODS: An enzyme-linked immunosorbent assay of binding between Helix aspersa (HAA) and serum IgA was performed in Japanese IgAN patients and the HAA-IgA binding levels were compared among IgAN patients (n = 41), patients with other forms of kidney disease (OKD, n = 43) and healthy controls (n = 38)...

UNLABELLED: Sopite syndrome is a disturbance caused by motion characterized by drowsiness and mood changes that may occur without the classic symptoms of motion sickness. Because sopite symptoms are often subtle, it is important to assess for their presence, and to distinguish true sopite symptoms from changes in mood and drowsiness that are due to non-motion related factors such as fatigue and boredom. We compared sopite symptoms in the optokinetic drum (OKD) with symptoms in a control condition in which the drum's motion cues were removed...

Phenylacetic acid (PA), a phytotoxic product of the bacteria accompanying the virulent nematode isolate OKD-3 was detected in the callus of Pinus thunbergii after inoculation with the nematode. The amount of PA detected was large enough to induced the formation and accumulation of benzoic acid (BA) and its conjugates in the callus. These results further support the hypotheses that PA is the pathogenic toxin and that the PA-producing bacterial strains accompanying the pathogenic nematode are the genuine pathogens of the pine wilt disease...
