No full textA Case of Bladder Paraganglioma Managed by Transurethral Approach, Using Holmium Laser
No full textA 78-year-old man was referred to our hospital with a bladder tumor. He suffered from headaches and palpitations aftervoiding. Cystoscopy and MRI showed a submucosal bladdertumorwhich localized submucosally without invasion to the muscularlayer . The tumorwas positive for 131I-MIBG scintigraphy and we diagnosed it as a bladderpar aganglioma. We enucleated the tumoren bloc from the bladderusing holmium laser via transurethral approach, with minimal alteration of blood pressure during the procedure. The enucleated tumorwas evacuated out of the bladderwith a morcellator

No full textA Case of Renal Subcapsular Cyst Successfully Treated with Endoscopic Ultrasound-Guided Transgastric Drainage of Pancreatic Pseudocyst
No full textA 49-year-old man presented with elevated serum creatinine. He had histories of pancreatic pseudocyst caused by alcoholic pancreatitis and right nephrectomy due to renal cell carcinoma. Computed tomographic scan demonstrated that a subcapsular renal cyst appeared adjacent to the pancreatic pseudocyst and compressed the parenchyma of the left kidney. Since the renal subcapsular cyst was suspected to directly communicate with the pancreatic pseudocyst, endoscopic ultrasound-guided transgastric drainage of pancreatic pseudocyst was performed. After the intervention, the renal subcapsular cyst disappeared without formation of a pancreatic fistula and renal dysfunction was promptly improved. He remains free of relapse for more than 1 year

No full textAn fMRI-study of leading and following using rhythmic tapping
No full textLeading and following is about synchronizing and joining actions in accordance with the differ- ences that the leader and follower roles provide. The neural reactivity representing these roles was measured in an explorative fMRI-study, where two persons lead and followed each other in finger tapping using simple, individual, pre-learnt rhythms. All participants acted both as leader and follower. Neural reactivity for both lead and follow related to social awareness and adaptation distributed over the lateral STG, STS and TPJ. Reactivity for follow contrasted with lead mostly reflected sensorimotor and rhythmic processing in cerebellum IV, V, somatosensory cortex and SMA. During leading, as opposed to following, neural reactivity was observed in the insula and bilaterally in the superior temporal gyrus, pointing toward empathy, sharing of feelings, temporal coding and social engagement. Areas for continuous adaptation, in the posterior cerebellum and Rolandic operculum, were activated during both leading and following. This study indicated mutual adaptation of leader and follower during tapping and that the roles gave rise to largely similar neuronal reactivity. The differences between the roles indicated that leading was more socially focused and following had more motoric- and temporally related neural reactivity
Comparison of resting-state functional and effective connectivity between default mode network and memory encoding related areas
No full textCurrently brain connectivity modelling, constructed from data acquired by non-invasive technique such as functional magnetic resonance imaging (fMRI), is a well-received approach to illustrate brain function. However, not all connectivity models contains equal amount of information. There are two types of connectivity model that could be constructed from fMRI data, functional and effective connectivity. Effective connectivity includes information about the direction of the connection, while functional connectivity does not. This makes interpretation of effective connectivity more meaningful than functional connectivity. The objective of this study is to show the improvement in interpretability of effective connectivity model in comparison to functional connectivity model. In this study, we show how the difference in the information contained within these two model impacts the interpretation of the resulting connectivity model by analyzing resting-state fMRI data on episodic memory-related cognitive function using CONN Toolbox bivariate correlation measurement for functional connectivity analysis and Tigramite causal discovery framework for effective connectivity analysis on an episodic memory related resting-state fMRI dataset. The comparison between functional and effective connectivity results show that effective connectivity contains more information than the functional connectivity, and the difference in the information contained within these two types of model could significantly impact the intepretation of true brain function. In conclusion, we show that for the connectivity between specific pair of brain regions, effective connectivity analysis reveals more informative characteristic of the connectivity in comparison to functional connectivity where the depicted connectivity lack any additional characteristic information such as the direction of the connection or whether it is a unidirectional or bidirectional. These additional information improve interpretability of brain connectivity study. Thus, we would like to emphasis the important of brain function study using effective connectivity modelling to obtain valid interpretation of true brain function as currently a large body of research in this field focuses only on functional connectivity model
