To study the effect of inhibitor of differentiation 3 (ID3) on radiotherapy in patients with rectal cancer and to explore its primary mechanism. Methods Cell proliferation and clonogenic assays were used to study the relationship between ID3 and radiosensitivity. Co-immunoprecipitation and immunofluorescence were performed to analyze the possible mechanism of ID3 in the radiosensitivity of colorectal cancer.

In the paper "On L∞-Induced stabilization of positive linear systems with distributed delays" consider the stabilization problem under L∞-gain scheme for positive linear systems with distributed time delays. Novelty and main contribution of this paper are two points. First, a characterization of L∞-gain is reformulated using novel comparison techniques involving steady states of upper scaled systems with peak values of exogenous disturbances.

Hepatitis B Virus (HBV) contributes to liver carcinogenesis via various epigenetic mechanisms. The newly defined epigenetics, epitranscriptomics regulation, has been reported to involve in multiple cancers including Hepatocellular Carcinoma (HCC). Our previous study found that HBx, HBV encodes X protein, mediated H3K4me3 modification in WDR5-dependent manner to involve in HBV infection and contribute to oncogene expression.

Potato virus Y (PVY) is a major pathogen of potatoes with major impact on global agricultural production. Resistance to PVY can be achieved by engineering potatoes to express a recessive, resistant allele of eukaryotic translation initiation factor eIF4E, a host dependency factor essential to PVY replication.

Gibberellin (GA) is one of the most essential phytohormones that modulate plant growth and development. Jute (Corchorus sp.) is the second most important source of bast fiber. Our result has shown that exogenous GA can positively regulate jute height and related characteristics which mean increasing endogenous GA production will help to get a jute variety with improved characteristics.

The methanol-regulated AOX1 promoter (PAOX1) is the most widely used promoter in the production of recombinant proteins in the methylotrophic yeast Pichia pastoris. However, as the tight regulation and methanol dependence of PAOX1 restricts its application, it is necessary to develop a flexible induction system to avoid the problems of methanol without losing the advantages of PAOX1.

e-Learning systems increasingly support learning management and self-organized learning processes. Since the latter have been studied in the field of progressive education extensively, it is worthwhile to consider them for developing digital learning environments to support self-regulated learning processes. In this paper we aim at transforming one of the most prominent and sustainable approaches to self-organized learning, the “Dalton Plan” as proposed by Helen Parkhurst.

This paper proposes an enhanced nonlinear control technique based on a combination of feedback linearization (FBL) and resonant regulator as tracking controllers for the doublyfed induction generator (DFIG) wind turbine system under unbalanced grid voltage. A nonlinear model of DFIG wind turbine system with the rotor-side converter (RSC) is firstly linearized, not by small signal analysis.

A brief overview of the model followed by results from simulations performed to validate the model is presented. Simulations illustrate stable behavior of the reactor dynamics and temperature feedback effects to reactivity excursions. Stable and smooth changes at various nodal temperatures are also observed. Control strategies for molten-salt reactor operation are discussed, followed by an illustration of the open-loop load-following capability of the molten-salt breeder reactor system.
