1Strength degradation of sandstone and granodiorite under uniaxial cyclic loading显示文摘Change in mechanical properties of rocks under static loading has been widely studied and documented.However, the response of rocks to cyclic loads is still a much-debated topic. Fatigue is the phenomenon when rocks under cyclic loading fail at much lower strength as compared to those subjected to the monotonic loading conditions. A few selected cored granodiorite and sandstone specimens have been subjected to uniaxial cyclic compression tests to obtain the unconfined fatigue strength and life. This study seeks to examine the effects of cyclic loading conditions, loading amplitude and applied stress level on the fatigue life of sandstone, as a soft rock, and granodiorite, as a hard rock, under uniaxial compression test. One aim of this study is to determine which of the loading conditions has a stronger effect on rock fatigue response. The fatigue response of hard rocks and soft rocks is also compared. It is shown that the loading amplitude is the most important factor affecting the cyclic response of the tested rocks. The more the loading amplitude, the shorter the fatigue life, and the greater the strength degradation. The granodiorite specimens showed more strength degradation compared to the sandstone specimens when subjected to cyclic loading. It is shown that failure modes of specimens under cyclic loadings are different from those under static loadings. More local cracks were observed under cyclic loadings especially for granodiorite rock specimens.Rashid Geranmayeh Vaneghi Behnam Ferdosi Achola D.Okoth Barnabas Kuek 2018Journal of Rock Mechanics and Geotechnical Engineering2018,10,1:11

3Predicting enhancer-promoter interaction from genomic sequence with deep neural networks显示文摘Background:In the human genome,distal enhancers are involved in regulating target genes through proximal promoters by forming enhancer-promoter interactions.Although recently developed high-throughput experimental approaches have allowed us to recognize potential enhancer-promoter interactions genome-wide,it is still largely unclear to what extent the sequence-level information encoded in our genome help guide such interactions.Methods:Here we report a new computational method (named 'SPEID') using deep learning models to predict enhancer-promoter interactions based on sequence-based features only,when the locations of putative enhancers and promoters in a particular cell type are given.Results:Our results across six different cell types demonstrate that SPEID is effective in predicting enhancerpromoter interactions as compared to state-of-the-art methods that only use information from a single cell type.As a proof-of-principle,we also applied SPEID to identify somatic non-coding mutations in melanoma samples that may have reduced enhancer-promoter interactions in tumor genomes.Conclusions^ This work demonstrates that deep learning models can help reveal that sequence-based features alone are sufficient to reliably predict enhancer-promoter interactions genome-wide.Shashank Singh Yang Yang Barnabas Poczos Jian Ma 2019Frontiers of Electrical and Electronic Engineering in China2019,7,2:8
4Yang-tonifying traditional Chinese medicinal plants and their potential phytoandrogenic activity显示文摘The concept of phytoandrogens, plants that contain androgens or those that stimulate androgenic activity in men, is relatively new. In traditional Chinese medicine a number of phytoandrogens are classified in medicinal plant restoratives for reinforcing yang, and they find their application in the treatment of the kidney yang deficiency diseases. In this review, the phytoandrogens used in traditional Chinese medicine are listed, and their proven applications in the treatment of kidney yang deficiency diseases, such as sexual disorders, cancer, and obesity and associated metabolic syndromes are presented. As a background, the mechanism of action of androgens, their synthesis and metabolism, the interrelations of androgens and estrogens, as well as the state of art methods to detect and analyze these hormonal activities in medicinal plants are discussed.Munyangaju Jose Edouard MIAO Lin FAN Guan-Wei Barnabas Bessem Orang Ojong ZHEN Hu ZHANG Ju GAO Xiu-Mei ZHU Yan 2014Chinese Journal of Natural Medicines2014,12,5:5
5Role of estrogen in angiogenesis in cardiovascular diseases显示文摘The formation of new blood vessels from existing ones is a major process of angiogenesis and it is most effective in the vascular systems。 The physiological process like hypoxia inducible factors involved in the regeneration of damaged tissues varies within the vascular systems in the endothelium and could be limited due to some major angiogenic growth factors like vascular endothelial growth factor, fibroblast growth factors and epidermal growth factor among others which bring about this cellular vascular regrowth。 These physiological processes leading to cellular vascular regrowth could be a major function for the treatment of cardiovascular diseases such as ischemia and atherosclerosis。 Estrogens are one of the known factors within the cellular mechanisms that could initiate repairs to the damaged vascular tissues, since estrogens are known inducers of angiogenesis leading to this cellular regrowth。 Research has also shown that this cellular regrowth is induced by vascular angiogenic growth factors via the estrogen receptors。 In this review we will attempt to summarize the main angiogenic growth factors involved in these physiological processes leading to angiogenesis and possible new mechanisms that could lead to this vascular regrowth。 And also we will try to summarize some reports on the effect of estrogen on these physiological processes leading to angiogenesis in cardiovascular diseases。Oche Barnabas Hong Wang Xiu-Mei Gao 2013Journal of Geriatric Cardiology2013,10,4:5

7Repeat endoscopic retrograde cholangiopancreaticography after failed initial precut sphincterotomy for biliary cannulation显示文摘AIM: To investigate the outcome of repeating endoscopic retrograde cholangiopancreaticography(ERCP) after initially failed precut sphincterotomy to achieve biliary cannulation.METHODS: In this retrospective study, consecutive ERCPs performed between January 2009 and September 2012 were included. Data from our endoscopy and radiology reporting databases were analysed for use of precut sphincterotomy, biliary access rate, repeat ERCP rate and complications. Patients with initially failed precut sphincterotomy were identified.RESULTS: From 1839 consecutive ERCPs, 187(10%) patients underwent a precut sphincterotomy during the initial ERCP in attempts to cannulate a native papilla. The initial precut was successful in 79/187(42%). ERCP was repeated in 89/108(82%) of patients with failed initial precut sphincterotomy after a median interval of 4 d, leading to successful biliary cannulation in 69/89(78%). In 5 patients a third ERCP was attempted(successful in 4 cases). Overall, repeat ERCP after failed precut at the index ERCP was successful in 73/89 patients(82%). Complications after precut-sphincterotomy were observed in 32/187(17%) patients including pancreatitis(13%), retroperitoneal perforations(1%), biliary sepsis(0.5%) and haemorrhage(3%).CONCLUSION: The high success rate of biliary cannulation in a second attempt ERCP justifies repeating ERCP within 2-7 d after unsuccessful precut sphincterotomy before more invasive approaches should be considered.Michael Pavlides Ashley Barnabas Nilesh Fernandopulle Adam A Bailey Jane Collier Jane Phillips-Hughes Anthony Ellis Roger Chapman Barbara Braden 2014World Journal of Gastroenterology2014,20,36:3
