Association of chronic kidney disease and coronary artery disease in 1,010 consecutive patients undergoing coronary angiography.

Abstract: BACKGROUND Patients with chronic kidney disease (CKD) are more likely to have complications due to cardiovascular disease (CVD). This study was performed to investigate the prevalence of chronic kidney disease (CKD) and the relation of CKD and number of stenosed coronary vessels in patients who had undergone coronary angiography with suspected coronary artery disease (CAD). METHODS The data of 1,010 consecutive patients who underwent coronary angiography for suspected CAD in Zhongda Hospital were analyzed. Estimated glomerular filtration rate (eGFR) was calculated with the abbreviated Modified Diet in Renal Disease (MDRD) Study equation. CKD was defined as presence of eGFR <60 ml/min per 1.73 m(2) and/or proteinuria. Luminal narrowing with at least 1 lesion =50% in the main branches of the coronary artery was considered as CAD. The number of stenotic arteries was recorded (1- to 3-vessel disease [VD]). A significant stenosis in the left main trunk was scored as 2-VD. RESULTS Patients with CAD had a significantly higher prevalence of CKD compared with patients without CAD (18.8% vs. 5.4%, p<0.001). CKD was significantly associated with CAD, 2-VD and 3-VD, versus without CAD (0-VD) (odds ratio [OR] = 2.163; 95% confidence interval [95% CI], 1.296-3.611; OR=2.478; 95% CI, 1.288-4.766; OR=2.504; 95% CI, 1.271-4.933; respectively) after adjustment for covariates. CONCLUSIONS There was a higher prevalence of CKD in patients with CAD diagnosed by coronary angiography, and it increased with the number of stenosed coronary vessels. CKD is a critical risk factor for CAD, especially 3-VD.

Bright YAG:Ce Nanorod Phosphors Prepared via a Partial Wet Chemical Route and Biolabeling Applications.

Abstract: Cerium-doped yttrium aluminum garnet (YAG:Ce) nanorods were prepared via a partial wet chemical route followed by a calcination process by using Al2O3 nanorods as both templates and the reactant. These novel well-crystallized YAG:Ce phosphors with a 200–300 nm diameter and a 2–3 μm length have a high specific surface area while being virtually devoid of surface defects. The YAG:Ce nanorod phosphors possess good luminescent properties compared with granular YAG:Ce phosphors. Photoluminescence quantum yields of YAG:Ce nanorod phosphors are higher than those of granular ones. The YAG:Ce nanorod phosphors exhibit two luminescent decay times due to their unique morphology. The YAG:Ce nanorods exhibited good cytocompatibility with bone marrow mesenchymal stem cells and can be used as biolabel nanoparticles in bioimaging.

Microflowers Comprised of Cu/CuxO/NC Nanosheets as Electrocatalysts and Horseradish Peroxidase Mimics

Abstract: The preparation of various nanomaterials with hierarchical structure from metal–organic frameworks (MOFs) has attracted a lot of attention due to their abundant diversity in composition and structu...

I and i

Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality. Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

疟原虫var基因转换速率变化导致抗原变异[英]／Paul H, Robert P, Christodoulou Z, et al//Proc Natl Acad Sci U S A

Abstract: 抗原变异可使得多种致病微生物易于逃避宿主免疫应答。表达在感染红细胞表面的恶性疟原虫红细胞表面蛋白1（PfPMP1）与感染红细胞、内皮细胞、树突状细胞以及胎盘的单个或多个受体作用，在黏附及免疫逃避中起关键的作用。每个单倍体基因组var基因家族编码约60种成员，通过启动转录不同的var基因变异体为抗原变异提供了分子基础。

The chemistry of two-dimensional layered transition metal dichalcogenide nanosheets

Abstract: Ultrathin two-dimensional nanosheets of layered transition metal dichalcogenides (TMDs) are fundamentally and technologically intriguing. In contrast to the graphene sheet, they are chemically versatile. Mono- or few-layered TMDs - obtained either through exfoliation of bulk materials or bottom-up syntheses - are direct-gap semiconductors whose bandgap energy, as well as carrier type (n- or p-type), varies between compounds depending on their composition, structure and dimensionality. In this Review, we describe how the tunable electronic structure of TMDs makes them attractive for a variety of applications. They have been investigated as chemically active electrocatalysts for hydrogen evolution and hydrosulfurization, as well as electrically active materials in opto-electronics. Their morphologies and properties are also useful for energy storage applications such as electrodes for Li-ion batteries and supercapacitors.
