3Tissue specificity of DNA damage response and tumorigenesis显示文摘The genome of cells is constantly challenged by DNA damages from endogenous metabolism and environmental agents.These damages could potentially lead to genomic instability and thus to tumorigenesis.To cope with the threats, cells have evolved an intricate network, namely DNA damage response(DDR) system that senses and deals with the lesions of DNA.Although the DDR operates by relatively uniform principles, different tissues give rise to distinct types of DNA damages combined with high diversity of microenvironments across tissues.In this review, we discuss recent findings on specific DNA damage among different tissues as well as the main DNA repair way in corresponding microenvironments, highlighting tissue specificity of DDR and tumorigenesis.We hope the current review will provide further insights into molecular process of tumorigenesis and generate new strategies for cancer treatment.Siman Sun Michael DOsterman Mo Li 2019Cancer Biology & Medicine2019,16,3:3
4Farmers’perception of climate change and adaptation strategies in the Dabus watershed,North-West Ethiopia显示文摘Introduction:This study is aimed at analyzing farmers’perception and adaptation to climate change in the Dabus watershed.It is based on analysis of data collected from 734 randomly selected farm household heads substantiated with Focus Group Discussions and field observations.Methods:The study employed descriptive methods to assess farmers’perception of climate change,local indicators of climate change and types of adaptation measures exercised to cope up with the risk of the change in climate.The study also employed the Heckman sample selection model to analyze the two-step process of adaptation to climate change which initially requires farmers’perception that climate is changing prior to responding to the changes through adaptation measures.Results:Based on the model result educational attainment,the age of the head of the household,the number of crop failures in the past,changes in temperature and precipitation significantly influenced farmers’perception of climate change in wet lowland parts of the study area.In dry lowland condition,farming experience,climate information,duration of food shortage,and the number of crop failures experienced determined farmers’perception of climate change.Farmers’adaptation decision in both the wet and dry lowland conditions is influenced by household size,the gender of household head,cultivated land size,education,farm experience,non-farm income,income from livestock,climate information,extension advice,farm-home distance and number of parcels.However,the direction of influence and significance level of most of the explanatory variables vary between the two parts of the study area.Conclusions:In line with the results,any intervention that promotes the use of adaptation measures to climate change may account for location-specific factors that determine farmers'perception of climate change and adaptive responses thereof.Paulos Asrat Belay Simane 2018Ecological Processes2018,7,1:2
5Vulnerability analysis of smallholder farmers to climate variability and change: an agroecological system-based approach in the Fincha’a sub-basin of the upper Blue Nile Basin of Ethiopia显示文摘Background:Ethiopia is frequently cited as a country that is highly vulnerable to climate variability and change.The country’s high vulnerability arises mostly from climate-sensitive agricultural sector that suffers a lot from risks associated with rainfall variability.The vulnerability factors(exposure,sensitivity,and adaptive capacity)of the agricultural livelihoods to climate variability and change differ across agro-ecological systems(AESs).Therefore,the aim of this study was to analyze AES-specific vulnerability of smallholder farmers to climate variability and change in the Fincha’a sub-basin.We surveyed 380 respondents from 4 AESs(highland,midland,wetland,and lowland)randomly selected.Furthermore,focus group discussion and key informant interviews were also performed to supplement and substantiate the quantitative data.Livelihood vulnerability index was employed to analyze the levels of smallholders’agriculture vulnerability to climate variability and change.Data on socioeconomic and biophysical attribute were collected and combined into the indices and vulnerability score was calculated for each agro-ecological system.Results:Considerable variation was observed across the agro-ecological systems in profile,indicator,and the three livelihood vulnerability indices-Intergovernmental Panel on Climate Change dimensions(exposure,sensitivity,and adaptive capacity)of vulnerability.The lowland AES exhibited higher exposure,low adaptive capacity,and high vulnerability,while the midland AES demonstrated lower exposure,higher adaptive capacity,and lower vulnerability.The wetland and highland AESs scored intermediate results.Conclusion:Our results suggest that resilience-building adaptation strategies are vital to reduce the vulnerability of smallholder farmers.The measures taken should consider site-specific agro-ecological system requirements to reduce the vulnerability of smallholder mixed crop-livestock agriculture system.Since the approach based on the long-term realization of the community,any strategy designed based on such assessments is applicable to local condition.Israel Tessema Belay Simane 2019Ecological Processes2019,8,1:2
6Embedded BCI Rehabilitation System for Stroke显示文摘In stroke rehabilitation,rehabilitation equipments can help with the training.But traditional equipments are not convenient to carry,which limits patients to use related rehabilitation techniques.To solve this kind of problem,a new embedded rehabilitation system based on brain computer interface(BCI)is proposed in this paper.The system is based on motor imagery(MI)therapy,in which electroencephalogram(EEG)is evoked by grasping motor imageries of left and right hands,then collected by a wearable device.The EEG is transmitted to a Raspberry Pie processing unit through Bluetooth and decoded as the instructions to control the equipment extension.Users experience the limb movement through the visual feedback so as to achieve active rehabilitation.A pilot study shows that the user can control the movement of the rehabilitation equipment through his mind,and the equipment is convenient to carry.The study provides a new way to stroke rehabilitation.Wanzeng Kong Siman Fu Bin Deng Hong Zeng Jianhai Zhang Shijie Guo 2019Journal of Beijing Institute of Technology2019,28,1:2
