We conducted a genome-wide association study of type 2 diabetes (T2D) using 459,359 SNPs in a Japanese population with a three-stage study design (stage 1, 4,470 cases and 3,071 controls; stage 2, 2,886 cases and 3,087 controls; stage 3, 3,622 cases and 2,356 controls). We identified new associations in UBE2E2 on chromosome 3 and in C2CD4A-C2CD4B on chromosome 15 at genome-wide significant levels (rs7612463 in UBE2E2, combined P = 2.27 ? 10<SUP>??9</SUP>; rs7172432 in C2CD4A-C2CD4B, combined P = 3.66 ? 10<SUP>??9</SUP>). The association of these two loci with T2D was replicated in other east Asian populations. In the European populations, the C2CD4A-C2CD4B locus was significantly associated with T2D, and a combined analysis of all populations gave P = 8.78 ? 10<SUP>??14</SUP>, whereas the UBE2E2 locus did not show association to T2D. In conclusion, we identified two new loci at UBE2E2 and C2CD4A-C2CD4B associated with susceptibility to T2D.
Solubilization and formulation of chrysosplenol C in solid dispersion with hydrophilic carriers
Ng, C.L.,Lee, S.E.,Lee, J.K.,Kim, T.H.,Jang, W.S.,Choi, J.S.,Kim, Y.H.,Kim, J.K.,Park, J.S. Elsevier/North Holland 2016 International journal of pharmaceutics Vol.512 No.1
We investigated how to overcome problems associated with the solubility, dissolution, and oral bioavailability of the poorly water-soluble drug compound, chrysosplenol C (CRSP), as well as the effects of single and binary hydrophilic polymers (PVP K-25 and/or PEG 6000) on the solubility and dissolution parameters of CRSP. Then an optimized formulation was further developed with a surfactant. To select a surfactant suitable for a CRSP-loaded solid dispersion (SD), the solubility of CRSP in distilled water containing 1% surfactant was compared with the solubilities in other surfactants. Sodium lauryl sulfate (SLS) showed the highest drug solubility. Overall, a formulation containing CRSP, binary hydrophilic polymers (PVP and PEG 6000), and SLS at a ratio of 2.0/0.2/1.1/0.7 showed the optimum in vitro release profile. This optimized formulation had better safety properties than pure CRSP in cell viability examinations. SD formulations were characterized by scanning electron microscopy (SEM), differential scanning calorimetry (DSC), X-ray powder diffraction (XRD), and Fourier-transform infrared (FT-IR) spectroscopy. Our optimized SD formulation is expected to improve the bioavailability of CRPS because it improves the solubility and dissolution rate of CRSP.

Objective: To assess the prognosis of surgically-staged non-invasive uterine clear cell carcinoma (UCCC), and to determine the role of adjuvant therapy. Methods: A multicenter, retrospective department database review was performed to identify patients with UCCC who underwent surgical treatment between 1997 and 2016 at 8 Gynecologic Oncology Centers. Demographic, clinicopathological, and survival data were collected. Results: A total of 232 women with UCCC were identified. Of these, 53 (22.8%) had surgically-staged non-invasive UCCC. Twelve patients (22.6%) were upstaged at surgical assessment, including a 5.6% rate of lymphatic dissemination (3/53). Of those, 1 had stage IIIA, 1 had stage IIIC1, 1 had stage IIIC2, and 9 had stage IVB disease. Of the 9 women with stage IVB disease, 5 had isolated omental involvement indicating omentum as the most common metastatic site. UCCC limited only to the endometrium with no extra-uterine disease was confirmed in 41 women (73.3%) after surgical staging. Of those, 13 women (32%) were observed without adjuvant treatment whereas 28 patients (68%) underwent adjuvant therapy. The 5-year disease-free survival rates for patients with and without adjuvant treatment were 100.0% vs. 74.1%, respectively (p=0.060). Conclusion: Extra-uterine disease may occur in the absence of myometrial invasion (MMI), therefore comprehensive surgical staging including omentectomy should be the standard of care for women with UCCC regardless of the depth of MMI. Larger cohorts are needed in order to clarify the necessity of adjuvant treatment for women with UCCC truly confined to the endometrium.

<P><B>OBJECTIVE—</B> Recent genome-wide association studies have identified six novel genes for type 2 diabetes and obesity and confirmed <I>TCF7L2</I> as the major type 2 diabetes gene to date in Europeans.

In addition, the A allele of rs8050136 at <I>FTO</I> was associated with increased BMI in the control subjects (<I>P</I><SUB>unadjusted</SUB> = 0.008). However, we did not observe significant association of any genetic variants with surrogate measures of insulin secretion or insulin sensitivity indexes in a subset of 2,662 control subjects. Compared with subjects carrying zero, one, or two risk alleles, each additional risk allele was associated with 17% increased risk, and there was an up to 3.3-fold increased risk for type 2 diabetes in those carrying eight or more risk alleles. Despite most of the effect sizes being similar between Asians and Europeans in the meta-analyses, the ethnic differences in risk allele frequencies in most of these genes lead to variable attributable risks in these two populations.</P><P><B>CONCLUSIONS—</B> Our findings support the important but differential contribution of these genetic variants to type 2 diabetes and obesity in Asians compared with Europeans.</P>

In the present work, the effect of manganese oxide (MnO2) additions (0, 0.5, 1 and 5 wt%) on the properties of ceria-dopedscandia stabilized zirconia (10Sc1CeSZ) was investigated over the temperature range of 1400 oC to 1550 oC. The results showedthat the addition up to 1 wt% had negligible effect on the mechanical properties of the ceramic. The samples containing upto 1 wt% MnO2 attained above 97.5% relative density, Vickers hardness of 13-14 GPa and fracture toughness of about3 MPam1/2. In addition, it was revealed that the 0.5 wt% MnO2 addition was beneficial in suppressing the cubic zirconia graingrowth i.e. the highest average grain size was measured at 4.9 µm when sintered at 1550 oC as compared to 9.9 µm measuredfor the undoped zirconia when sintered at the same temperature. On the other hand, the addition of 5 wt% MnO2 was foundto be detrimental to the densification and properties of the zirconia, particularly when sintered at higher temperatures. Thiswas attributed to the accelerated grain growth of the doped samples, i.e. the grain size increased by 2 fold, to 18.6 µm whensintered at 1550 oC.

Indium oxide, tin oxide and indium tin oxide nanowires have been grown by vapor deposition on Si and quartz substrates. Under the growth conditions used, pure SiOx nanowires, a mixture of SiOx and indium oxide, tin oxide or indium tin oxide nanostructures, or pure indium oxide, tin oxide or indium tin oxide nanostructures could be obtained at different substrate temperatures. The growth mechanism of the obtained nanostructures at different substrate temperatures is discussed. Optical and electrical properties of the deposited pure indium oxide, tin oxide or indium tin oxide nanostructures have been measured, and low sheet resistances on quartz substrates have been obtained for indium oxide and indium tin oxide nanostructures.
Mode Change of a Gamma-Ray Pulsar, PSR J2021+4026
Zhao, J.,Ng, C. W.,Lin, L. C. C.,Takata, J.,Cai, Y.,Hu, C.-P.,Yen, D. C. C.,Tam, P. H. T.,Hui, C. Y.,Kong, A. K. H.,Cheng, K. S. American Astronomical Society 2017 The Astrophysical journal Vol.842 No.1
<P>A glitch of a pulsar is known as a sudden increase in the spin frequency and spin-down rate (frequency time derivative), and it can be caused by a sudden release of the stress built up in the solid crust of the star or pinned vortices in the superfluid interior. PSR J2021+4026 is the first pulsar that shows a significant change in the gamma-ray flux and pulse profile at the glitch that occurred around 2011 October 16. We report the results of timing and spectral analysis of PSR J2021+4026 using similar to 8 yr Fermi. Large Area Telescope data. We find that the pulsar stayed at a high spin-down rate (similar to 4% higher than the pre-glitch value) and a low gamma-ray state (similar to 18% lower) for about 3 yr. after the glitch. Around 2014 December, the spin-down rate and gamma-ray flux gradually returned to pre-glitch values within a timescale of a. few months. The phase-resolved spectra and pulse profiles after the relaxation are also consistent with those before the glitch. The observed long-term evolution of the spin-down rate and the gamma-ray flux indicates that the glitch triggered a mode change in the global magnetosphere. We speculate that the glitch changed. the local magnetic field structure around the polar cap and/or the inclination angle of the. dipole axis, leading to. a change in the electric current circulating in the. magnetosphere.</P>
