1Incidence and mortality of female breast cancer in the AsiaPacific region显示文摘Objective: To provide an overview of the incidence and mortality of female breast cancer for countries in the Asia-Pacific region.Methods: Statistical information about breast cancer was obtained from publicly available cancer registry and mortality databases(such as GLOBOCAN), and supplemented with data requested from individual cancer registries. Rates were directly age-standardised to the Segi World Standard population and trends were analysed using joinpoint models.Results: Breast cancer was the most common type of cancer among females in the region, accounting for 18% of all cases in 2012, and was the fourth most common cause of cancer-related deaths(9%). Although incidence rates remain much higher in New Zealand and Australia, rapid rises in recent years were observed in several Asian countries. Large increases in breast cancer mortality rates also occurred in many areas, particularly Malaysia and Thailand, in contrast to stabilising trends in Hong Kong and Singapore, while decreases have been recorded in Australia and New Zealand. Mortality trends tended to be more favourable for women aged under 50 compared to those who were 50 years or older. Conclusion: It is anticipated that incidence rates of breast cancer in developing countries throughout the Asia-Pacific region will continue to increase. Early detection and access to optimal treatment are the keys to reducing breast cancerrelated mortality, but cultural and economic obstacles persist. Consequently, the challenge is to customise breast cancer control initiatives to the particular needs of each country to ensure the best possible outcomes.Danny R.Youlden Susanna M.Cramb Cheng Har Yip Peter D.Baade 2014Cancer Biology & Medicine2014,11,2:35

3Prevention of vertical transmission of hepatitis B virus infection显示文摘Hepatitis B virus(HBV)is the leading cause of chronic viral hepatitis.Annually,almost two million children younger than 5 years acquire the infection,mostly through vertical or horizontal transmission in early life.Vertical transmission of HBV is a high efficacy phenomenon ranging,in the absence of any preventive interventions,from 70%to 90%for hepatitis e antigen positive mothers and from 10%to 40%for hepatitis e antigen-negative mothers.Maternal viraemia is a preeminent risk factor for vertical transmission of HBV.Maternal screening is the first step to prevent vertical transmission of HBV.Hepatitis B passive and active immunoprophylaxis at birth together with antiviral treatment of highly viraemic mothers are the key strategies for global elimination of HBV infection.Strategies are needed to promote implementation of birth-dose vaccination and hepatitis B immunoglobulins in low-and middle-income countries where the prevalence of the infection is at the highest.Piero Veronese Icilio Dodi Susanna Esposito Giuseppe Indolfi 2021World Journal of Gastroenterology2021,27,26:10
4A six-year descriptive epidemiological study of human coronavirus infections in hospitalized patients in Hong Kong显示文摘We conducted a six-year epidemiological study on human coronaviruses(HCoVs) circulating in Hong Kong, using 8275 nasopharyngeal samples from patients with acute respiratory tract infections. HCoVs were detected in 77(0.93%) of the samples by a pan-HCoV RT-PCR assay. The most frequently detected HCoV species was HCoV-OC43(0.58%), followed by HCoV-229E(0.15%),HCoV-HKU1(0.13%) and HCoV-NL63(0.07%). HCoVs were detected throughout the study period(September 2008–August 2014), with the highest detection rate from September 2010 to August2011(22/1500, 1.47%). Different seasonal patterns of each HCoV species in Hong Kong were noted.HCoV-OC43 was predominant in the fall and winter, whereas HCoV-HKU1 showed peak activity in winter, with a few cases occurred in spring and summer. HCoV-229 E mainly occurred in winter and spring, while HCoV-NL63 was predominant in summer and autumn. HCoVs most commonly infect the elderly and young children, with median age of 79.5 years(range, 22 days to 95 years).Intriguingly, the detection rate of HCoV-OC43 in the age group of > 80 years(26/2380, 1.09%) was significantly higher than that in the age group of 0–10 years(12/2529, 0.47%)(P < 0.05). These data provides new insight into the epidemiology of coronaviruses.Cyril C.Y.Yip Carol S.F.Lam Hayes K.H.Luk Emily Y.M.Wong Rodney A.Lee Lok-Yee So Kwok-Hung Chan Vincent C.C.Cheng Kwok-Yung Yuen Patrick C.Y.Woo Susanna K.P.Lau 2016Virologica Sinica2016,31,1:9
5Viral manipulation of cellular protein conjugation pathways: The SUMO lesson显示文摘Small ubiquitin-like modifier(SUMO)ylation is a key posttranslational modification mechanism that controls the function of a plethora of proteins and biological processes. Given its central regulatory role, it is not surprising that it is widely exploited by viruses. A number of viral proteins are known to modify and/or be modified by the SUMOylation system to exert their function, to create a cellular environment more favorable for virus survival and propagation, and to prevent host antiviral responses. Since the SUMO pathway is a multi-step cascade, viral proteins engage with it at many levels, to advance and favor each stage of a typical infection cycle: replication, viral assembly and immune evasion. Here we review the current knowledge on the interplay between the host SUMO system and viral lifecycle.Domenico Mattoscio Chiara V Segré Susanna Chiocca 2013World Journal of Virology2013,2,2:8

9Design and preliminary validation of a tool for the simulation of train braking performance显示文摘Train braking performance is important for the safety and reliability of railway systems.The availability of a tool that allows evaluating such performance on the basis of the main train features can be useful for train system designers to choose proper dimensions for and optimize train's subsystems.This paper presents a modular tool for the prediction of train braking performance,with a particular attention to the accurate prediction of stopping distances.The tool takes into account different loading and operating conditions,in order to verify the safety requirements prescribed by European technical specifications for interoperability of high-speed trains and the corresponding EN regulations.The numerical results given by the tool were verified and validated by comparison with experimental data,considering as benchmark case an Ansaldo EMU V250 train—a European high-speed train—currently developed for Belgium and Netherlands high-speed lines,on which technical information and experimental data directly recorded during the preliminary tests were available.An accurate identification of the influence of the braking pad friction factor on braking performances allowed obtaining reliable results.Luca Pugi Monica Malvezzi Susanna Papini Gregorio Vettori 2013Journal of Modern Transportation2013,21,4:5

13Silvicultural alternatives to conventional even-aged forest man-agement-what limits global adoption?显示文摘Background: The development of forestry as a scientific and management discipline over the last two centuries has mainly emphasized intensive management operations focused on increased commodity production, mostly wood. This 'conventional' forest management approach has typically favored production of even-aged, single-species stands. While alternative management regimes have generally received less attention, this has been changing over the last three decades, especially in countries with developed economies. Reasons for this change include a combination of new information and concerns about the ecological consequences of intensive forestry practices and a willingness on the part of many forest owners and society to embrace a wider set of management objectives. Alternative silvicultural approaches are characterized by a set of fundamental principles, including avoidance of clearcutting, an emphasis on structural diversity and small-scale variability, deployment of mixed species with natural regeneration,and avoidance of intensive site-preparation methods.Methods: Our compilation of the authors' experiences and perspectives from various parts of the world aims to initiate a larger discussion concerning the constraints to and the potential of adopting alternative silvicultural practices.Results: The results suggest that a wider adoption of alternative silvicultural practices is currently hindered by a suite of ecological, economic, logistical, informational, cultural, and historical constraints. Individual contexts display their own unique combinations and relative significance of these constraints, and accordingly, targeted efforts, such as regulations and incentives, may help to overcome specific challenges.Conclusions: In a broader context, we propose that less emphases on strict applications of principles and on stand structures might provide additional flexibility and facilitate the adoption of alternative silvicultural regimes in a broader set of circumstances. At the same time, the acceptance of alternative silvicultural systems as the 'preferred or default mode of management' wil necessitate and benefit from the continued development of the scientific basis and valuation of a variety of ecosystem goods and services. This publication is aimed to further the discussion in this context.Klaus J Puettmann Scott McG Wilson Susan C Baker Pablo J Donoso Lars Dr?ssler Girma Amente Brian D Harvey Thomas Knoke Yuanchang Lu Susanna Nocentini Francis E Putz Toshiya Yoshida Jürgen Bauhus 2015Forest Ecosystems2015,2,2:4
14Transcriptional Activation and Production of Tryptophan-Derived Secondary Metabolites in Arabidopsis Roots Contributes to the Defense against the Fungal Vascular Pathogen Verticillium Iongisporum显示文摘忍受土壤的真菌的病原体 Verticillium longisporum 在象 oilseed 强奸那样的 Brassicaceae 主人植物上引起脉管的疾病。真菌开拓殖民地于根木部并且向上搬到疾病症状变得可见的叶子。为早基因正式就职把 Arabidopsis 用作一个模型,我们分别地在孢子萌芽以后并且在根外皮的穿入期间立即响应菌丝的生长执行了根 transcriptome 分析。感染的根显示出象抄写因素的激活那样的基因表示的快速的 reprogramming,应力 -- ,并且防卫相关的基因。这里,我们集中了于导致导出色氨酸的第二等的代谢物的生产的高度协调的基因正式就职。在叶子的以前的研究证明 CYP81F2 和 PEN2 (PENETRATION2 ) 编码的酶执行抗真菌的吲哚 glucosinolate (IGS ) 的形成代谢物。在感染 Verticillium 的根,我们发现 transcriptional CYP81F2 和 PEN2 的激活相当或相同的事物 PEL1 (PEN2-LIKE1 ) ,而是抗真菌的 IGS 故障产品的没有增加。相反, indole-3-carboxylic 酸(I3CA ) 和 phytoalexin camalexin 在感染的根积累了,但是仅仅 camalexin 在 vitro 禁止了 Verticillium 生长。而导致 camalexin 或 CYP81F2 依赖的 IGS 代谢物的单个新陈代谢的小径的基因混乱没改变导致 Verticillium 的疾病症状, cyp79b2 cyp79b3 异种在两个分支损害了导致了显著地提高的危险性。因此,我们的数据提供卓见进根特定的早防卫并且对脉管的病原体作为活跃抗真菌的混合物建议导出色氨酸的代谢物。Tim Iven Stefanie Konig Seema Singh Susanna A.

15Two-dimensional gel electrophoresis in bacterial proteomics显示文摘Two-dimensional gel electrophoresis(2-DE)is a gel-based technique widely used for analyzing the pro-tein composition of biological samples.It is capable of resolving complex mixtures containing more than a thousand protein components into individual protein spots through the coupling of two orthogonal bio-physical separation techniques:isoelectric focusing(first dimension)and polyacrylamide gel electrophore-sis(second dimension).2-DE is ideally suited for ana-lyzing the entire expressed protein complement of a bacterial cell:its proteome.Its relative simplicity and good reproducibility have led to 2-DE being widely used for exploring proteomics within a wide range of envi-ronmental and medically-relevant bacteria.Here we give a broad overview of the basic principles and his-torical development of gel-based proteomics,and how this powerful approach can be applied for studying bacterial biology and physiology.We highlight specific 2-DE applications that can be used to analyze when,where and how much proteins are expressed.The links between proteomics,genomics and mass spectrometry are discussed.We explore how proteomics involving tandem mass spectrometry can be used to analyze(post-translational)protein modifications or to identify proteins of unknown origin by de novo peptide se-quencing.The use of proteome fractionation tech-niques and non-gel-based proteomic approaches are also discussed.We highlight how the analysis of pro-teins secreted by bacterial cells(secretomes or exo-proteomes)can be used to study infection processes or the immune response.This review is aimed at non-specialists who wish to gain a concise,compre-hensive and contemporary overview of the nature and applications of bacterial proteomics.Shirly O.T.Curreem Rory M.Watt Susanna K.P.Lau Patrick C.Y.Woo 2012Protein & Cell2012,3,5:4

17Insights from human sleep research on neural mechanisms of Alzheimer’s disease显示文摘Alzheimer's disease(AD)is considered as the major cause of dementia and affects about 50 million people in world population,with an expected increase of 27%in the coming decades,as reported by the most recent AD statistics.The fast-growing empirical evidence is highlighting the close relationship between sleep and AD since the preclinical stage of the disease,pointing to an important role of sleep in the occurrence and progression of AD.Susanna Cordone Luigi De Gennaro 2020Neural Regeneration Research2020,15,7:3
18High level HIV-1 DNA concentrations in brain tissues differentiate patients with post-HAART AIDS dementia complex or cardiovascular disease from those with AIDS显示文摘Highly active antiretroviral treatment(HAART) has had a significant impact on survival of individuals with acquired immunodeficiency syndrome(AIDS);however,with the longer life-span of patients with AIDS,there is increasing prevalence of AIDS dementia complex(ADC) and other non-AIDS-defining illness,and cardiovascular diseases(CVD) are also common.The influence of these varied disease processes on HIV-1 DNA concentration in brain tissues has not been thoroughly assessed in the post-HAART era.The purpose of the current study is to clarify the impacts of ADC and other complications of HIV disease on the viral load in the brains in AIDS patients with post-HARRT.We examined autopsy specimens from the brains of thirteen patients who died from complications of AIDS with quantitative polymerase chain reaction(QPCR).All but one patient had received HAART prior to death since 1995.Two patients died with severe CVD,multiple cerebrovascular atherosclerosis(CVA) throughout the brain and five patients died with ADC.Six patients had no ADC/CVA.A QPCR was used to measure the presence of HIV-1 DNA in six brain tissues(meninges,frontal grey matter,frontal white matter,temporal subcortex,cerebellum and basal ganglia).In the post-HARRT era,for non-ADC/CVA patients,HIV-1 DNA concentration in brain tissues was statistically higher than that in patients with ADC.In a new finding,two patients who suffered from severe CVD,especially CVA,also had high concentrations of HIV-1 in brain compartments not showing ADC related changes.To our knowledge,this is the first report of a relationship between the CVA and HIV-1 viral burden in brain.The current observations suggest that HAART-resistant HIV reservoirs may survive within ADC lesions of the brain as well as the macrophage rich atherosclerosis,which needs to be confirmed by more AIDS cases with CVA.GALLIGAN Derek C.

19Incidental extravascular findings in computed tomographic angiography for planning or monitoring endovascular aortic aneurysm repair: Smoker patients, increased lung cancer prevalence?显示文摘AIM To validate the feasibility of high resolution computed tomography(HRCT) of the lung prior to computed tomography angiography(CTA) in assessing incidental thoracic findings during endovascular aortic aneurysm repair(EVAR) planning or follow-up.METHODS We conducted a retrospective study among 181 patients(143 men, mean age 71 years, range 50-94) referred to our centre for CTA EVAR planning or followup. HRCT and CTA were performed before or after 1 or 12 mo respectively to EVAR in all patients. All HRCT examinations were reviewed by two radiologists with 15 and 8 years experience in thoracic imaging. The results were compared with histology, bronchoscopy or follow-up HRCT in 12, 8 and 82 nodules respectively. RESULTS There were a total of 102 suspected nodules in 92 HRCT examinations, with a mean of 1.79 nodules per patient and an average diameter of 9.2 mm(range 4-56 mm). Eightynine out of 181 HRCTs resulted negative for the presence of suspected nodules with a mean smoking history of 10 pack-years(p-y, range 5-18 p-y). Eighty-two out of 102(76.4%) of the nodules met criteria for computed tomography follow-up, to exclude the malignant evolution. Of the remaining 20 nodules, 10 out of 20(50%) nodules, suspected for malignancy, underwent biopsy and then surgical intervention that confirmed the neoplastic nature: 4(20%) adenocarcinomas, 4(20%) squamous cell carcinomas, 1(5%) small cell lung cancer and 1(5%) breast cancer metastasis); 8 out of 20(40%) underwent bronchoscopy(8 pneumonia) and 2 out of 20(10%) underwent biopsy with the diagnosis of sarcoidosis.CONCLUSION HRCT in EVAR planning and follow-up allows to correctly identify patients requiring additional treatments, especially in case of lung cancer.Maria Antonietta Mazzei Susanna Guerrini Francesco Gentili Giuseppe Galzerano Francesco Setacci Domenico Benevento Francesco Giuseppe Mazzei Luca Volterrani Carlo Setacci 2017World Journal of Radiology2017,9,7:3
20Adaptive link layer security architecture for telecommand communications in space networks显示文摘Impressive advances in space technology are enabling complex missions, with potentially significant and long term impacts on human life and activities. In the vision of future space exploration, communication links among planets, satellites,spacecrafts and crewed vehicles will be designed according to a new paradigm, known as the disruption tolerant networking. In this scenario, space channel peculiarities impose a massive reengineering of many of the protocols usually adopted in terrestrial networks; among them, security solutions are to be deeply reviewed, and tailored to the specific space requirements. Security is to be provided not only to the payload data exchanged on the network, but also to the telecommands sent to a spacecraft,along possibly differentiated paths. Starting from the secure space telecommand design developed by the Consultative Committee for Space Data Systems as a response to agency-based requirements, an adaptive link layer security architecture is proposed to address some of the challenges for future space networks. Based on the analysis of the communication environment and the error diffusion properties of the authentication algorithms, a suitable mechanism is proposed to classify frame retransmission requests on the basis of the originating event(error or security attack) and reduce the impact of security operations. An adaptive algorithm to optimize the space control protocol, based on estimates of the time varying space channel, is also presented. The simulation results clearly demonstrate that the proposed architecture is feasible and efficient, especially when facing malicious attacks against frame transmission.Lei Zhang Chengjin An Susanna Spinsante Chaojing Tang 2014Journal of Systems Engineering and Electronics2014,25,3:3
