It affects the macula region of the retina leading to severe vision loss and legal blindness in individuals 〉 50 years of age (Wong et al., 2014). The precise aetiology of AMD is unknown but smoking, age and genetic factors are major risk factors for AMD predisposition (Ding et al., 2009). The genetic basis of AMD is well described with a recent study from the International AMD gene consortium (IAMDGC) reporting 52 genetic variants across 34 loci associated with the risk of AMD pathogenesis and explaining more than 50% of the genetic heritabilitv of the disease (Fritsche et al., 2016).展开更多

Both ERα and ERβ modulate the expression of a variety of genes in the cells. Neurons and glial cells express ERa and ERβ. Many studies so far from our and other laboratories have firmly established the mode of actions that ERα and ERβ agonists are very promising anti-inflammatory and neuroprotective agents in the treatment of neurodegenera- rive diseases and injuries including spinal cord injury (SCI) (Chakrabarti et al., 2014a).展开更多

In recent years, the study of community resilience is becoming popular among scholars because of its perspective on disaster prevention and mitigation. In this study, we apply database retrieval to untangle community resilience-related papers from multiple directions. We analyze the connotation, attribute, and composition of community, resilience, and community resilience comprehensively by summarizing important issues and research progress in community resilience. Challenges and shortcomings faced by community resilience development are also determined. Moreover, we put forward the research directions that future research can focus on. Through literature review, current research on community resilience focuses on the following aspects: "infrastructure construction," "crowd in the community," "economic resilience,""social capital," and "measurement of community resilience." Such research is not yet systematic and relatively decentralized. The attention to collective resilience in the community is relatively weak, which makes achieving the goal of "people-oriented and systematic control" difficult.Therefore, this study states that the development of future community resilience should stand from the perspective of"system of system" and build on knowledge and tools of various relevant domains. Therefore, public needs and participation are highlighted as breakthrough points. The research should integrate infrastructure and economic resilience, social resource allocation, network connection,and other aspects to build a holistic and functional resilient community.展开更多

Front Lu Lin, 120°52′25″E and 23°28′07″N, a 2862 m peak in the Yu Shan National Park. The construction of Lu Lin Observatory was finished on January 14, 1999. The initial study of Lu Lin site was started since late 1989. Later on, a three year project was founded by the National Science Council (NSC) which supported the development of a modern seeing monitor for this site survey study from 1990 through 1993. The average seeing of Lu Lin site is about 1.39 arc second with average 200 clear nights annually. The sky background of this site is 20.72 mag/arcsec 2 in V band and 21.22 mag/arcsec 2 in B band. The Lu Lin observatory is developed for both research and education activity. A homemade 76 cm Super Light Telescope (SLT) and three TAOS’s 50 cm robotic telescopes will be the two major research facilities. The SLT is expected to be operated in the fall of 1999. We are proposing a pilot program to perform SLT observations of time varying astrophysical objects exploiting the unique geophysical location (e. g. time and longitudinal coverage) of Taiwan at the Western Pacific Rim in such topics of emerging interest. The TAOS’s telescopes will be installed in the late 1999 for the survey work of Kuiper Belt Objects. A wireless T1 Network system will also be build up for future remote observation.展开更多

In this paper, we review researches on lightweight metals spun at elevated temperatures since they are difficult to deform at room temperature. These metals include light alloys, such as titanium, magnesium and aluminum alloys, and metal composites. Then, the heating methods used in the hot spinning process and the treatment methods employed for the temperature boundary condition in finite element analyses for the process were discussed. Finally, the future development directions for the hot spinning process of lightweight but difficult-to-deform alloys were highlighted.展开更多

As a result,the gap between high and low incidence countries is decreasing. The disease,therefore,has an important economic impact on the healthcare system. Advances in recent years in pharmacogenetics and clinical pharmacology have allowed for the development of treatment strategies adjusted to the patient profile. Concurrently,new drugs aimed at inflammatory targets have been developed that may expand future treatment options. This review examines advances in the optimization of existing drug treatments and the development of novel treatment options for IBD.展开更多

To improve CO<sub>2</sub> separation performance of polymer membranes, mixed matrix membranes (MMMs) are developed. The concept of MMM is illustrated distinctly. Suitable polymer and inorganic or organic fillers for MMMs are summarized. Possible interface morphologies between polymer and filler, and the effect of interface morphologies on gas transport properties of MMMs are summarized. The methods to improve compatibility between polymer and filler are introduced. There are eight methods including silane coupling, Grignard treatment, incorporation of additive, grafting, in situ polymerization, polydopamine coating, particle fusion approach and polymer functionalization. To achieve higher productivity for industrial application, mixed matrix composite membranes are developed. The recent development on hollow fiber and flat mixed matrix composite membrane is reviewed in detail. Last, the future trend of MMM is forecasted.展开更多

文摘The taxonomic status of Bufo species in East Asia,particularly those closely related to B.gargarizans,has been controversial for over half a century,and recent molecular studies further fueled the dispute.Whether B.andrewsi,B.bankorensis,B.minshanicus,B.sachalinensis,B.tibetanus,and B.tuberculatus constitute valid species or are geographic or ecological variants of B.gargarizans is at the centre of the discussion.Most of these forms possess morphological diagnostic traits,but those differences are minimal and often inconsistent.Molecular data produced many contradictory patterns.Lack of clear diagnostic characters,different usage or definition of various names,mis-identified specimens,limited amount of data or samples,and frequent inter-specific hybridization may all have contributed to the current controversies.Some contradiction may also result from differences between similarity-based clustering and gene tree-based branching patterns.Nevertheless,a dominant allopatric differentiation pattern within this species complex is apparent,and several regional population groups have been identified.Some of the groups resemble old names(e.g.B.minshanicus,B.tibetanus),while others are new.These groups may represent geographic or ecological variants,incipient species,or valid species,and the current data do not warrant a convincing taxonomic revision.To move forward,a single study with comprehensive sampling and genomic data is needed to establish a solid framework,which will define naturally existing population clusters/lineages,and detect their levels of divergence and approximate geographic boundaries.Morphological and ecological examination will follow to understand their biology,determine their taxonomic status,and identify consistent diagnostic characters if necessary.

文摘Hot spinning process has attracted significant attention because it can be used to manufacture complex parts, extend the forming limit of materials, decrease forming forces and reduce process chains. In this paper, we review researches on lightweight metals spun at elevated temperatures since they are difficult to deform at room temperature. These metals include light alloys, such as titanium, magnesium and aluminum alloys, and metal composites. Then, the heating methods used in the hot spinning process and the treatment methods employed for the temperature boundary condition in finite element analyses for the process were discussed. Finally, the future development directions for the hot spinning process of lightweight but difficult-to-deform alloys were highlighted.
文摘In recent years,the incidence of inflammatory bowel disease(IBD) has been on the rise,extending to countries where it was infrequent in the past. As a result,the gap between high and low incidence countries is decreasing. The disease,therefore,has an important economic impact on the healthcare system. Advances in recent years in pharmacogenetics and clinical pharmacology have allowed for the development of treatment strategies adjusted to the patient profile. Concurrently,new drugs aimed at inflammatory targets have been developed that may expand future treatment options. This review examines advances in the optimization of existing drug treatments and the development of novel treatment options for IBD.

文摘Recent advances on mixed matrix membrane for CO<sub>2</sub> separation are reviewed in this paper. To improve CO<sub>2</sub> separation performance of polymer membranes, mixed matrix membranes (MMMs) are developed. The concept of MMM is illustrated distinctly. Suitable polymer and inorganic or organic fillers for MMMs are summarized. Possible interface morphologies between polymer and filler, and the effect of interface morphologies on gas transport properties of MMMs are summarized. The methods to improve compatibility between polymer and filler are introduced. There are eight methods including silane coupling, Grignard treatment, incorporation of additive, grafting, in situ polymerization, polydopamine coating, particle fusion approach and polymer functionalization. To achieve higher productivity for industrial application, mixed matrix composite membranes are developed. The recent development on hollow fiber and flat mixed matrix composite membrane is reviewed in detail. Last, the future trend of MMM is forecasted.
文摘With changes in lifestyle and diet worldwide,the prevalence of hyperlipidemic acute pancreatitis(HLAP)has greatly increased,and it has become the most common cause of acute pancreatitis not due to gallstones or alcohol.There are many available therapies for HLAP,including oral lipid-lowering agents,intravenous insulin,heparin,and therapeutic plasmapheresis(TPE).It is believed that the risk and severity of HLAP increase with rising levels of serum triglycerides(TG),thus a rapid decrease in serum TG level is the key to the successful management of HLAP.TPE has emerged as an effective modality in rapidly reducing serum TG levels.However,due to its cost and accessibility,TPE remains poorly evaluated until now.Some studies revealed its efficacy in helping to treat and prevent the recurrence,while some studies suggested that TG levels were not correlated with disease severity,mortality,or length of hospital stay.Thus TPE might have no beneficial effect for the outcome.This article gives an overview of the published evidence of TPE in the treatment of HLAP and outlines current evidence regarding individual outcome predictors,adverse effects of the procedure,and TPE in special occasions such as for pregnant patients and patients with diabetic ketoacidosis.Future direction of TPE research for HLAP is also discussed in this review.
文摘Viral hepatitis continues to be a major health concern leading to hepatic decompensation ranging from acute hepatitis to cirrhosis and hepatocellular carcinoma.The hepatic and extrahepatic manifestations are not only debilitating but also associated with a significant economic burden.Over the last two decades,the field of virology has made significant breakthroughs leading to a better understanding of the pathophysiology of viral hepatitis,which in turn has led to new therapeutic options.The advent of direct-acting antiviral agents changed the landscape of hepatitis C virus(HCV)therapy,and new drugs are in the pipeline for chronic hepatitis B virus(HBV)treatment.There has also been a significant emphasis on screening and surveillance programs,widespread availability of vaccines,and linkage of care.Despite these efforts,significant gaps persist in care,and there is a pressing need for increased collaboration and teamwork across the globe to achieve a reduction of disease burden and elimination of HBV and HCV.
