　　报告一：     

　　（1）主　题：The function and mechanism of a novel noncoding RNA-FP236383.10

　　（2）主讲人：杨军　生命科学与技术学院博士后 

　　（3）交流内容：

　　Tumorigenesis, a complicated process, involves expression alterations of many biomolecules. Pancreatic cancer is a gastrointestinal cancer with higher malignancy. It is mainly origind fron pancreatic ductal epithelial cells, diagnosed and treated with difficulty. FP236383.10 is a novel noncoding RNA discovered in our previous research. Here we focused on the function and mechanism of FP236383.10 in pancreatic cancer cells PANC1 and MIA PaCa2. The main contents and results are as follows: (1) FP236383.10 locates in cytoplasm and nucleus: qRT-PCR detection after cytoplasmic and nucleic parts isolated and fluorescence in situ hybridization results indicated its expression in both parts. (2) FP236383.10 could bind to RPL10 and is stabilized by RPL10: co-localization image predicted the combination of RPL10 and FP236383.10. RNA-IP results further demonstrated their binding. After detected their relation, used antinomycin D to block RNA synthesis whose results indicated RPL10 helped with stabilizing FP236383.10. (3) FP236383.10 participates in pancreatic cancer development (4) FP236383.10 knock-down affects a series of proteins expression.

　　（1）主　题：Predicting brain age with deep learning from raw imaging data

　　（2）主讲人：王飞帆　生命科学与技术学院博士后 

　　（3）交流内容：

　　The human brain changes across the adult lifespan. This process of brain ageing occurs in accord with a general decline in cognitive performance, cognitive ageing. Although the changes associated with brain ageing are not explicitly pathological, with increasing age comes increasing risk of neurodegenerative disease and dementia. Since the effects of ageing on the brain vary greatly between individuals, advancing our understanding of brain ageing and identifying biomarkers of the process are vital to help improve detection of early-stage neurodegeneration and predict age-related cognitive decline. In this talk, we briefly discuss the credentials of brain-predicted age as a biomarker of individual differences in the brain ageing process. Predictive modelling approach based on deep learning, specifically three dimensional convolutional neural networks,  has been applied to raw T1-weighted structural MRI data. We will talk about the advances of using deep learning in this task as well as the difficulties and challenges we are facing in the development of the prediction model.

　　报告三：     

　　（1）主　题：Deep learning approach to head motion detection and correction

　　（2）主讲人：Dr. Benjamin Klugah-Brown博士后 

　　（3）交流内容：

　　Since the introduction of MRI/fMRI in studying the human brain, image corruption due to obvious/or more subtle motion artefacts are an everyday challenge to researchers and clinical scientist for the past decades. Many techniques in an attempt to mitigate this image degradation have been proposed. However, most of these techniques lack or are unable to capture subtle and non-linear properties, thus acknowledging the fact that a small shift in the image may have a large consequence on the interpretation of results such as functional connectivity, thus, the correction of motion artefacts from fMRI is nontrivial. The aim of this project is therefore to approach the problem using deep learning method, which shall involves three steps;(1) Generating a motion_field  (3-translations,3-rotations and deformation) which will be used for deep learning,(2) applying deep learning architecture with the motion_field and (3) develop a procedure (online /offline) for correction. In this presentation, we will discuss the various none-deep learning methods that have been used to tackle motion correction. Then, introduce the deep learning approaches and initial results including some challenges.
