Combinatorial Genetics of RNA Binding Proteins for Lifespan Regulation in C. elegans

RNA binding proteins control post-transcriptional aspects of gene regulation. While transcriptional control over the aging process has been well-established, less is known about post-transcriptional control over the aging process. We have used CRISPR/Cas9 genetics to study combinations of RNA binding proteins in C. elegan, a transparent nematode or roundworm one millimeter in length, and their role in aging. The manner in which the research was conducted was through experimental laboratory work in which the lifespan of the nematodes was monitored until their death. The three mutations affecting RNA binding proteins that assays were performed with are exc-7, fox-1, and mbl-1. We found that double mutants have stronger effects on lifespan than single mutants. Thus, RNA binding protein mutations, although separate, appeared to be functionally connected. These observations, though being considered in C. elegans, could have a substantive impact on the study of gene regulation in humans and in turn, provide insight into the human aging processes

A Novel Progressive Multi-label Classifier for Classincremental Data

In this paper, a progressive learning algorithm for multi-label classification to learn new labels while retaining the knowledge of previous labels is designed. New output neurons corresponding to new labels are added and the neural network connections and parameters are automatically restructured as if the label has been introduced from the beginning. This work is the first of the kind in multi-label classifier for class-incremental learning. It is useful for real-world applications such as robotics where streaming data are available and the number of labels is often unknown. Based on the Extreme Learning Machine framework, a novel universal classifier with plug and play capabilities for progressive multi-label classification is developed. Experimental results on various benchmark synthetic and real datasets validate the efficiency and effectiveness of our proposed algorithm.Comment: 5 pages, 3 figures, 4 table

Update on potential medical treatments for encapsulating peritoneal sclerosis; human and experimental data

Encapsulating peritoneal sclerosis (EPS) is an infrequent but serious complication of peritoneal dialysis (PD). The pathogenesis is unknown but speculation is ongoing. The current management of EPS focuses on prevention and treatment of the inflammatory and fibrotic changes at the level of the peritoneal membrane with immunosuppressive and antifibrotic agents, respectively. This article reviews the currently available human and animal data on potential agents to prevent and/or treat EPS. We propose a strategy for early diagnose EPS in an attempt to avoid the development of the full-blown and potentially life-threatening clinical syndrome of EPS. Future research should focus on studying potential prophylactic and therapeutic agents in humans in large, multicenter, randomized trials but also on early detection of EPS in the inflammatory phase by means of biomarkers and the establishment of a composite EPS score
