Polarized synchronous light scattering characterization of the interaction of proteins with sodium dodecyl sulfonate
XiaoHui Zhao,ChengZhi Huang
Chinese Science Bulletin , 2007, DOI: 10.1007/s11434-007-0092-5
Abstract: In acid buffer solution, proteins with positive charge can react with anion surfactant and result in a great enhancement of synchronous light scattering (SLS) signals. In this contribution, the correlative experiment was made to compare the interaction of human serum albumin (HSA) and immunoglobulin G (IgG) with sodium dodecyl sulfonate (SDS). Based on the measurements of the polarization light scattering signals, a new method of scattering polarization was constituted to distinguish these two interaction systems with molecular weight difference (HSA 66 kDa; IgG 150 kDa). The results were consistent with the data measured by dynamic light scattering (DLS) technique.

Mathematics , 2014,
Abstract: The aim of this paper is to define and study Drinfeld twists for monoidal Hom-bialgebras. We show that a new Hom-bialgebra could be constructed by changing the coproduct of a monoidal Hom-bialgebra via a Drinfeld twist, and this construction preserves $R$-matrixes if there exist one. Moreover, their representation categories are monoidal isomorphic.

Safety and Efficacy of Biodegradable Drug-Eluting vs. Bare Metal Stents: A Meta-Analysis from Randomized Trials
Yangguang Yin, Yao Zhang, Xiaohui Zhao
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0099648
Abstract: Background Biodegradable polymeric coatings have been proposed as a promising strategy to enhance biocompatibility and improve the delayed healing in the vessel. However, the efficacy and safety of biodegradable polymer drug-eluting stents (BP-DES) vs. bare metal stents (BMS) are unknown. The aim of this study was to perform a meta-analysis of randomized controlled trials (RCTs) comparing the outcomes of BP-DES vs. BMS. Methods and Results PubMed, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) were searched for randomized clinical trials, until December 2013, that compared any of approved BP-DES and BMS. Efficacy endpoints were target-vessel revascularization (TVR), target-lesion revascularization (TLR) and in-stent late loss (ISLL). Safety endpoints were death, myocardial infarction (MI), definite stent thrombosis (DST). The meta-analysis included 7 RCTs with 2,409 patients. As compared with BMS, there was a significantly reduced TVR (OR [95% CI] = 0.37 [0.28–0.50]), ISLL (OR [95% CI] = ?0.41 [?0.48–0.34]) and TLR (OR [95% CI] = 0.38 [0.27–0.52]) in BP-DES patients. However, there were no difference for safety outcomes between BP-DES and BMS. Conclusions BP-DES is more effective in reducing ISLL, TVR and TLR, as safe as standard BMS with regard to death, ST and MI. Further large RCTs with long-term follow-up are warranted to better define the relative merits of BP-DES.
A Low-Carbon Dispatch Model in a Wind Power Integrated System Considering Wind Speed Forecasting and Energy-Environmental Efficiency
Daojun Chen,Qingwu Gong,Bichang Zou,Xiaohui Zhang,Jian Zhao
Energies , 2012, DOI: 10.3390/en5041245
Abstract: This paper introduces the “Energy-Environmental Efficiency” concept of building a low-carbon dispatch model of wind-incorporated power systems from the perspective of environmental protection and low-carbon dispatch promotion based on the existing economic environmental dispatch. A rolling auto-regressive and moving-average model is adopted to forecast wind speeds for the next 24 h and reduce the disadvantages brought about to the power system dispatch by wind speed fluctuations. A fuzzy satisfaction-maximizing approach is employed to convert the multi-objective decision-making problem in the low-carbon dispatch model into a single nonlinear one. Particle swarm optimization with a simulated annealing algorithm hybrid is used for better solutions. Simulation results show that the energy-environmental efficiency concept benefits the optimization of the proposed power system dispatch, and the proposed low-carbon dispatch model is reasonable and practical.
Concomitant sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman Disease) and diffuse large B-cell lymphoma: a case report
James C Moore, Xiaohui Zhao, Edward L Nelson
Journal of Medical Case Reports , 2008, DOI: 10.1186/1752-1947-2-70
Abstract: This report provides details of a case with co-existing sinus histiocytosis with massive lymphadenopathy and diffuse large B cell non-Hodgkin's lymphoma. This case is the fifth described case of simultaneous Rosai-Dorfman Disease and concurrent non-Hodgkin's lymphoma. Unfortunately, the diagnosis of a clinically aggressive diffuse large B cell lymphoma was made at autopsy. The aggressive biological behavior of the diffuse large B cell lymphoma in this patient may have been related to the underlying immune dysregulation believed to be part of the pathophysiology of Rosai-Dorfman Disease.Taken together this report and the preceding reports of Rosai-Dorfman Disease and non-Hodgkin's lymphoma suggests that in cases with a diagnosis of Rosai-Dorfman Disease in the setting of prominent infradiaphragmatic lymphadenopathy, clinicians should maintain a high index of suspicion for the presence of occult non-Hodgkin's lymphoma especially if the clinical course is atypical for classic Rosai-Dorfman Disease.Sinus histiocytosis with massive lymphadenopathy (SHML), also known as Rosai-Dorfman Disease (RDD), is a rare entity first described in 1969 [1] that belongs to a group of non-malignant histiocytic disorders in which there is a pathologic increase in the number of histiocytes, mainly mononuclear phagocytic cells and the antigen-presenting cells of bone marrow origin [2], in nodal or extra-nodal sites. This entity frequently mimics a malignant neoplasm, however the clinical course can be variable ranging from spontaneous regression, to protracted periods of stable lymphadenopathy, to the less frequent observation of progressive lymphadenopathy [3]. Symptomatic cases generally respond to mild or limited therapy such as steroid treatment, although surgery, radiation therapy and cytotoxic therapy have also been used [3]. The etiology is still unknown although genetic, infectious, and inflammatory etiologies have been postulated. This report details a case of Rosai-Dorfman disease
Sea surface temperature and subtropical front movement in the South Tasman Sea during the last 800 ka

Abstract: Hemisphere mid-latitude westerlies contribute to the ventilation of the deep Southern Ocean (SO), and drive changes in atmospheric carbon dioxide (CO2) and the global climate. As the westerlies control directly oceanic fronts, the movement of the subtropical front (STF) reflects the westerlies migration. Thus it is important to understand the relationships between STF movement and the weaterlies, ventilation of the deep SO, ice volume and atmospheric CO2. To this end, we use two new high-resolution records from early Marine Isotope Stage (MIS) 20 (~800 ka) of sea surface temperature (SST) based on U 37 k’ paleo-thermometer and benthic oxygen isotope (δ18OB) at Ocean Drilling Program (ODP) Site 1170B in the southern Tasman Sea (STS), to construct linkages between the marine records and atmospheric proxies from Antarctic ice-cores. During the last 800 ka, the average SST (10.2°C) at Site 1170B is 1.8°C lower than today (annual average 12°C). The highest average SST of 11.6°C occurred during MIS 1, and the lowest average SST of 7.8°C occurred during MIS 2. The warmest and coldest records of 14.7°C and 6.2°C occurred in the MIS 5 and MIS 2, respectively. In the glacial-interglacial cycles of the last 800 ka, variability of reconstructed SST shows that the STF moved northward or southward more than 3° of latitude compared with its present location. In the warmest stage MIS 5, the STF shifted to its southernmost location of ~49°S. In contrast, in the coldest stage MIS 2, the STF moved to its northernmost location of ~43°S. In response to orbital cycles, the westerlies movement led ice volume and atmospheric CO2 changes, but it was in phase with change in Antarctic atmospheric temperature. Ice volume only preceded atmospheric CO2 only a little at the 23-ka precession band, lagged the atmospheric CO2 at the 100-ka eccentricity band, and was in phase with atmospheric CO2 at the 40-ka obliquity band.

Abstract: The singlet excited state lifetime of the chlorophyll a (Chl a) in cytochrome b 6 f (Cyt b 6 f) complex was reported to be shorter than that of free Chl a in methanol, but the value was different for Cyt b 6 f complexes from different sources (~200 and ~600 ps are the two measured results). The present study demonstrated that the singlet excited state lifetime is associated with the detergents n-dodecyl-β-D-maltoside (DDM) and n-octyl-β-D-glucopyranoside (β-OG), but has nothing to do with the different sources of Cyt b 6 f complexes. Compared with the Cyt b 6 f dissolved in β-OG, the Cyt b 6 f in DDM had a lower fluorescence yield, a lower photodegradation rate of Chl a, and a shorter lifetime of Chl a excited state. In short, the singlet excited state lifetime, ~200 ps, of the Chl a in Cyt b 6 f complex in DDM is closer to the true in vivo.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.2323.2326
Abstract: The purpose of this study is to evaluate the anatomic and functional outcomes of 23-gauge Transconjunctival Sutureless Vitrectomy (TSV) in primary reatment of uncomplicated pseudophakic Retinal Detachments (RD). In this prospective noncomparative interventional study, 32 eyes of 32 patients with RD after cataract surgery with phacoemulsification were evaluated. Primary pseudophakic RDs with macular detachment and proliferative vitreoretinopathy stage B or less were included in the study. The 23-gauge TSV, perfluorocarbon liquid injection followed by air exchange, endolaser photocoagulation and sulfur hexafluoride gas (20%) injection were applied to all eyes. Mean follow-up time was 9.3 months (range, 6-12 months). Retinal reattachment with a single operation was achieved in 93.75% of eyes and with additional surgery, the retina was reattached in 100% of eyes. Preoperative visual acuity was <20/200 in all eyes (range, hand motions to 20/400). Postoperative visual acuity was 20/40 or better in 15 eyes (46.88%) and 20/50 and 20/200 in 12 eyes (37.50%). No sutures were required to close the scleral and conjunctival openings. Postoperative complications were Transient hypotony in 2 eyes (6.25%) macular pucker in 2 eyes (6.25%) and cystoid macular edema in 2 eyes (6.25%).
