(S)-[5-Methyl-3-(3-methyl­thio­phen-2-yl)-4,5-dihydro­isoxazol-5-yl]methanol

In the title compound, C10H13NO2S, the thio­phene and isoxazoline rings are almost coplanar, the dihedral angle between their least-squares planes being 2.08 (1)°. The O—H atoms of the methyl hy­droxy group and the N atom of the isoxazole ring are orientated in the same direction to allow for the formation of inter­molecular O—H⋯N hydrogen bonds that lead to a supra­molecular chain along the a axis

Internal evaluation of a physically-based distributed model using data from a Mediterranean mountain catchment

An evaluation of the performance of a physically-based distributed model of a small Mediterennean mountain catchment is presented. This was carried out using hydrological response data, including measurements of runoff, soil moisture, phreactic surface level and actual evapotranspiration. A-priori model parameterisation was based as far as possible on property data measured in the catchment. Limited model calibration was required to identify an appropriate value for terms controlling water loss to a deeper regional aquifer. The model provided good results for an initial calibration period, when judge in terms of catchment discharge. However, model performance for runoff declined substantially when evaluated againts a consecutive, rather drier, period of data. Evaluation against other catchment responses allowed identification of the problems responsible for the observed lack of model robustness in flow simulation. In particular, it was shown that an incorrect parameterisation of the soil water was preventing adequate representation of drainage from soils during hydrogeraph recessions. This excess moisture was then being removed via an overestimation of evapotranspiration. It also appeared that the model underestimated canopy interception. The results presented here suggest that model evaluation against catchment scale variables summarising its water balance can be of great use in identifying problems with model parameterisation, even for distributed models. Evaluation using spatially distributed data yielded less useful information on model performance, owing to the relative sparseness of data points, and problems of mismatch of scale between the measurement and the model grid.This work was carried out as part of project VAHMPIRE (Validating Hydrological Models using Process Studies and Internal Data from Research Basins: tools for assessing the hydrological impacts of environmental change), which was funded by the European Commission Framework IV Environment and Climate Program (Contract No. ENV4- CT95-0134).

Assessment of Disease Severity and Quality of Life in Patients with Atopic Dermatitis from South Korea

BACKGROUND: Data illustrating the impact of atopic dermatitis (AD) on lives of adults with AD in South Korea are limited. OBJECTIVE: To assess the AD disease severity and its impact on quality of life (QoL) in patients with AD from South Korea. METHODS: Patients with AD utilizing the specialist dermatology services of major hospitals in South Korea were assessed for disease severity using Eczema Area and Severity Index (EASI) score, for QoL using Dermatology Life Quality Index (DLQI) (for QoL), and for comorbidities and treatment experience via retrospective review of 12-month medical records. Clinical and sociodemographic characteristics were also measured. RESULTS: Of the 1,163 patients, 695 (59.8%) were men (mean age [years]±standard deviation: 31.6±12.1). Overall, 52.9% (n=615) patients had moderate-to-severe disease (EASI\u3e7). The QoL of 72.3% (n=840) patients was affected moderately-to-severely (DLQI score: 6~30). Systemic immunosuppressants were used ≥1 over past 12 months in 51.9% (n=603) patients, and the most commonly used were cyclosporines (45.7%, n=531) and systemic corticosteroids (40.5%, n=471). Approximately, 10.8% (n=126) patients consulted or received treatment for AD-related eye problem. Of these, 40% (n=50) patients reported poor, very poor, or completely blind status; approximately, 16.7% patients (n=192) reported having depression or anxiety; and 35.5% (n=410) reported suicidal ideation or suicidal attempt. CONCLUSION: A large proportion of patients had moderate-to-severe AD, a compromised QoL, and ocular or mental health comorbidities, indicating a high disease burden despite systemic treatment. These findings highlight the importance of a holistic approach for the evaluation and treatment of patients with AD

Reversible splenial lesion on the corpus callosum in nonfulminant hepatitis A presenting as encephalopathy

Reversible focal lesions on the splenium of the corpus callosum (SCC) have been reported in patients with mild encephalitis/encephalopathy caused by various infectious agents, such as influenza, mumps, adenovirus, Varicella zoster, Escherichia coli, Legionella pneumophila, and Staphylococcus aureus. We report a case of a reversible SCC lesion causing reversible encephalopathy in nonfulminant hepatitis A. A 30-year-old healthy male with dysarthria and fever was admitted to our hospital. After admission his mental status became confused, and so we performed electroencephalography (EEG) and magnetic resonance imaging (MRI) of the brain, which revealed an intensified signal on diffusion-weighted imaging (DWI) at the SCC. His mental status improved 5 days after admission, and the SCC lesion had completely disappeared 15 days after admission

Clinicopathologic Study of Chromosomal Aberrations in Gastric Lymphomas of Korean Patients

Background : The incidence and clinical correlation of MALT1 translocation and numerical aberrations in Korean gastric MALT lymphoma patients have been rarely reported. We studied the incidence and clinicopathologic relationship of these chromosomal aberrations in Korean gastric lymphomas. Methods: Seventy-six gastric lymphomas, which consisted of 40 low grade MALT lymphoma, 4 high grade MALT lymphoma and 32 diffuse large B-cell lymphoma (DLBCL) cases, were analyzed for the detection of t(11;18) API2-MALT1, t(14;18) IgH-MALT1 and aneuploidies of chromosomes 3 or 18 using fluorescence in situ hybridization. Results : The t(11;18) was demonstrated in 3 low grade MALT lymphomas (7.5%) and one DLBCL, which was associated with advanced stage, deeper invasion, and disease progression or relapse. The t(14; 18) was demonstrated in none of these cases. Trisomy 3 and 18 were detected in 8 (11%) and 11 of 76 cases (12.5%) respectively, and found only in translocation-negative cases. Two of 4 high grade MALT lymphomas showed trisomy 18. All patients survived with successful second treatment after progression or relapse. Conclusions: The t(11;18) API2-MALT1 was not quite frequent in Korean low grade gastric MALT lymphomas and was associated with advanced clinical situations. Overall prognosis was good for long-term follow-up regardless of progression or relapse.Nakamura T, 2008, AM J GASTROENTEROL, V103, P62, DOI 10.1111/j.1572-0241.2007.01521.xNakamura S, 2007, GUT, V56, P1358, DOI 10.1136/gut.2006.123729Inagaki H, 2007, PATHOL INT, V57, P474, DOI 10.1111/j.1440-1827.2007.02128.xFukuhara N, 2007, GENE CHROMOSOME CANC, V46, P784, DOI 10.1002/gcc.20464Remstein ED, 2006, AM J SURG PATHOL, V30, P1546Du MQ, 2006, GUT, V55, P886, DOI 10.1136/gut.2004.061663Zhou YP, 2006, BRIT J HAEMATOL, V133, P35, DOI 10.1111/j.1365-2141.2006.05969.xWundisch T, 2005, J CLIN ONCOL, V23, P8018, DOI 10.1200/JCO.2005.02.3903Ye HT, 2005, J PATHOL, V205, P293, DOI 10.1002/path.1715Taji S, 2005, WORLD J GASTROENTERO, V11, P89Inagaki H, 2004, AM J SURG PATHOL, V28, P1560Tai YC, 2004, VIRCHOWS ARCH, V445, P506, DOI 10.1007/s00428-004-1096-zStreubel B, 2004, LEUKEMIA, V18, P1722, DOI 10.1038/sj.leu.2403501Penas EMM, 2003, LEUKEMIA, V17, P2225, DOI 10.1038/sj.leu.2403122Schreuder MI, 2003, BRIT J HAEMATOL, V123, P590Ye HT, 2003, BLOOD, V102, P1012, DOI 10.1182/blood-2002-11-3502Ye HT, 2003, BLOOD, V101, P2547, DOI 10.1182/blood-2002-10-3167Nakamura S, 2003, J CLIN PATHOL, V56, P36Remstein ED, 2002, AM J PATHOL, V161, P63Liu HX, 2002, GASTROENTEROLOGY, V122, P1286, DOI 10.1053/gast.2002.33047Starostik P, 2002, BLOOD, V99, P3Stollerman GH, 2002, J AM GERIATR SOC, V50, P3Yonezumi M, 2001, BRIT J HAEMATOL, V115, P588Liu HX, 2001, BLOOD, V98, P1182Inagaki H, 2001, AM J PATHOL, V158, P699JAFFE ES, 2001, PATHOLOGY GENETICS, P157Remstein ED, 2000, AM J PATHOL, V156, P1183Baens M, 2000, AM J PATHOL, V156, P1433Hoeve MA, 1999, LEUKEMIA, V13, P799ISAACSON PG, 1994, HUM PATHOL, V25, P1020

Epiblast Stem Cell Subpopulations Represent Mouse Embryos of Distinct Pregastrulation Stages

SummaryEmbryonic stem cells (ESCs) comprise at least two populations of cells with divergent states of pluripotency. Here, we show that epiblast stem cells (EpiSCs) also comprise two distinct cell populations that can be distinguished by the expression of a specific Oct4-GFP marker. These two subpopulations, Oct4-GFP positive and negative EpiSCs, are capable of converting into each other in vitro. Oct4-GFP positive and negative EpiSCs are distinct from ESCs with respect to global gene expression pattern, epigenetic profile, and Oct4 enhancer utilization. Oct4-GFP negative cells share features with cells of the late mouse epiblast and cannot form chimeras. However, Oct4-GFP positive EpiSCs, which only represent a minor EpiSC fraction, resemble cells of the early epiblast and can readily contribute to chimeras. Our findings suggest that the rare ability of EpiSCs to contribute to chimeras is due to the presence of the minor EpiSC fraction representing the early epiblast

Two-Step Generation of Oligodendrocyte Progenitor Cells From Mouse Fibroblasts for Spinal Cord Injury

Oligodendrocyte progenitor cells (OPCs) are attracting attention as the ideal cell therapy for spinal cord injury (SCI). Recently, advanced reprogramming and differentiation techniques have made it possible to generate therapeutic cells for treating SCI. In the present study, we used directly-induced neural stem cells (DNSCs) from fibroblasts to establish OPCs (DN-OPCs) capable of proliferation and confirmed their OPC-specific characteristics. Also, we evaluated the effect of transplanted DN-OPCs on SCI in rats. The DN-OPCs exhibited an OPC-specific phenotype and electrophysiological function and could be differentiated into oligodendrocytes. In the SCI model, transplanted DN-OPCs improved behavior recovery, and showed engraftment into the host spinal cord with expression of myelin basic protein. These results suggest that DN-OPCs could be a new source of potentially useful cells for treating SCI
