A deep attentive convolutional neural network for automatic grading of imbalanced diabetic retinopathy in retinal fundus images

Feng Li, shiqing tang, yuyang chen & Haidong Zou
Automated fine-grained diabetic retinopathy (DR) grading was of great significance for assisting ophthalmologists in monitoring DR and designing tailored treatments for patients. Nevertheless, it is a challenging task as a result of high intra-class variations, high inter-class similarities, small lesions, and imbalanced data distributions. The pivotal factor for the success in fine-grained DR grading is to discern more subtle associated lesion features, such as microaneurysms (MA), Hemorrhages (HM), soft exudates (SE), and hard exudates (HE)....

Shuai Wang, Huiting Li, Jiheng Liu, Qianqian Zhang, Wei Xu, Juanjuan Xiang, Li Fang, Ping Xu & Zheng Li
Abstract RNA methylation modifications, especially m6A mRNA modification, are known to be extensively involved in tumor development. However, the relationship between N3-methylcytidine (m3C) related genes and tumorigenesis has rarely been studied. In this research, we found that m3C-related genes were expressed at different levels and affected patients’ prognosis across multiple cancer types from The Cancer Genome Atlas and multi-omics levels. Importantly, methyltransferase-like proteins 2A (METTL2A) had a high amplification frequency (~ 7%) in patients with...

A general method for calculating power for GEE analysis of complete and incomplete stepped wedge cluster randomized trials

Ying Zhang, John S Preisser, Elizabeth L Turner, Paul J Rathouz, Mark Toles & Fan Li
Stepped wedge designs have uni-directional crossovers at randomly assigned time points (steps) where clusters switch from control to intervention condition. Incomplete stepped wedge designs are increasingly used in cluster randomized trials of health care interventions and have periods without data collection due to logistical, resource and patient-centered considerations. The development of sample size formulae for stepped wedge trials has primarily focused on complete designs and continuous responses. Addressing this gap, a general, fast, non-simulation based...
