IJMS, Vol. 18, Pages 1294: Age-Related Changes in Immunological and Physiological Responses Following Pulmonary Challenge

17-Jun-2017 | Miller, Edmund J. ; Linge, Helena M., International Journal of Molecular Sciences, 2017

This review examines the current status of knowledge of sepsis and pneumonia in the elderly population and how the dynamics of the pulmonary challenge affects outcome and consequences. Led by an unprecedented shift in demographics, where a larger proportion of the population will reach an older ...


Polarization and space charge performance in PVDF with MPB composition BCZT doped composite films

16-Jun-2017 | Haowei Lu, Lizhu Liu, Jiaqi Lin, Wenlong Yang, Ling Weng, Xiaorui Zhang, Gaoru Chen, Wei Huang, Journal of Applied Polymer Science, 2017

ABSTRACT The morphotropic phase boundary composition 47(Ba0.7Ca0.3)TiO3–0.53Ba(Zr0.2Ti0.8)O3 (calcium barium zirconate titanate, BCZT) were doped in polyvinylidene fluoride matrix by solution casting method. The effect of BCZT particles on polarization characteristics of composite films were ...


Immobilization of lipase onto N‐succinyl‐chitosan beads and its application in the enrichment of polyunsaturated fatty acids in fish oil

15-Jun-2017 | Shuai Cui, Qin‐Wei Zhou, Xiao‐Ling Wang, Si‐Qi Yang, Kai Chen, Zhi‐Yuan Dai, Yao‐Wen Huang, Tao Zhou, Journal of Food Biochemistry, 2017

Abstract Bovine pancreatic lipase was immobilized onto N‐succinyl‐chitosan beads by using N‐(3‐dimethylaminopropyl)‐N′‐ethylcarbodiimide (EDC)/N‐hydroxysuccinimide (NHS) as the activating agent. The immobilized lipase was characterized by Fourier transform infrared spectra and scanning ...


Ranking REACH registered neutral, ionizable and ionic organic chemicals based on their aquatic persistency and mobility

14-Jun-2017 | Hans Peter Heinrich Arp; Trevor N. Brown; Urs Berger; Sarah Hale, Journal of Environmental Monitoring, 2017

The contaminants that have the greatest chances of appearing in drinking water are those that are mobile enough in the aquatic environment to enter drinking water sources and persistent enough to survive treatment processes. Herein a screening procedure to rank neutral, ionizable and ionic ...


IJERPH, Vol. 14, Pages 638: Dissemination of Chronic Disease Self-Management Education (CDSME) Programs in the United States: Intervention Delivery by Rurality

14-Jun-2017 | Smith, Matthew Lee; Towne, Samuel D.; Herrera-Venson, Angelica ; Cameron, Kathleen ; Kulinski, Kristie P.; Lorig, Ka ..., International Journal of Environmental Research and Public Health, 2017

Background: Alongside the dramatic increase of older adults in the United States (U.S.), it is projected that the aging population residing in rural areas will continue to grow. As the prevalence of chronic diseases and multiple chronic conditions among adults continues to rise, there is ...


Materials, Vol. 10, Pages 650: Synthesis of Au NP@MoS2 Quantum Dots Core@Shell Nanocomposites for SERS Bio-Analysis and Label-Free Bio-Imaging

13-Jun-2017 | Fei, Xixi ; Liu, Zhiming ; Hou, Yuqing ; Li, Yi ; Yang, Guangcun ; Su, Chengkang ; Wang, Zhen ; Zhong, Huiqing ; Zhu ..., Materials, 2017

In this work, we report a facile method using MoS2 quantum dots (QDs) as reducers to directly react with HAuCl4 for the synthesis of Au nanoparticle@MoS2 quantum dots (Au NP@MoS2 QDs) core@shell nanocomposites with an ultrathin shell of ca. 1 nm. The prepared Au NP@MoS2 QDs reveal high surface ...


Reduced Graphene Oxide/Alumina, A Good Accelerant for Cellulose-Based Artificial Nacre with Excellent Mechanical, Barrier, and Conductive Properties

12-Jun-2017 | Kiran Shahzadi; Xueming Zhang; Imran Mohsin; Xuesong Ge; Yijun Jiang; Hui Peng; Huizhou Liu; Hui Li; Xindong Mu, ACS Nano, 2017

In this article, a simple strategy was employed to fabricate bioinspired hybrid composite with carboxymethyl cellulose (CMC), graphene oxide, and reduced graphene oxide/alumina (rGO/Al) by a facile solution casting method. The tensile strength and toughness of rGO/Al-CMC-GO can reach 586.6 ± 12 ...
