With the rapid development of nanotechnology in the recent decade, novel DNA and RNA delivery systems for gene therapy have become available that can be used instead of viral vectors. These non-viral vectors can be made of a variety of materials, including inorganic nanoparticles, carbon nanotubes, liposomes, protein and peptide-based nanoparticles, as well as nanoscale polymeric materials. They have as advantages over viral vectors a decreased immune response, and additionally offer flexibility in design, allowing them to be functionalized and targeted to specific sites in a biological system with low cytotoxicity. The focus of this review is to provide an overview of novel nanotechnology-based methods to deliver DNA and small interfering RNAs into biological systems.

Unlabelled: Endoplasmic reticulum (ER) stress due to obesity or systemic insulin resistance is an important pathogenic factor that could lead to pancreatic β-cell failure. We have previously reported that CCAAT/enhancer-binding protein β (C/EBPβ) is highly induced by ER stress in pancreatic β cells. Moreover, its accumulation hampers the response of these cells to ER stress by inhibiting the induction of the molecular chaperone 78 kDa glucose-regulated protein (GRP78).

Yet, several inherent limitations restrict applying the approaches to genes not suitable for RNA velocity inference due to complex transcriptional dynamics, low expression, or lacking splicing dynamics, or data of non-transcriptomic modality. Here, we present GraphVelo, a graph-based machine learning procedure that uses as input the RNA velocities inferred from existing methods and infers velocity vectors lying in the tangent space of the low-dimensional manifold formed by the single cell data.

Inherited retinal diseases (IRDs) are clinically and genetically heterogeneous disorders characterized by progressive photoreceptor degeneration and irreversible vision loss. MicroRNAs (miRNAs), a class of endogenous non-coding RNAs with post-transcriptional regulatory properties, are known to play a major role in retinal function, both in physiological and pathological conditions. Given their ability to simultaneously modulate multiple molecular pathways, miRNAs represent promising therapeutic tools for disorders with high genetic heterogeneity, such as IRDs.

Studies have suggested animals as possible reservoir hosts for flaviviruses transmitted by Aedes mosquitoes; however, there is limited evidence for the dengue virus in Malaysia. One of the possible ways to determine the zoonotic potential for any pathogen transmission is through blood meal analysis which can provide valuable insights into the feeding preferences of the mosquitoes. Unfortunately, limited information is available on the feeding preferences of Aedes mosquitoes in Malaysia.

Mosquito-borne diseases have wreaked havoc on human health, with consequences dramatically increasing in recent years. The incidence of mosquito-borne diseases is closely linked to the locations that are chosen for urban development. The aim of this study was to provide characteristics of mosquito breeding sites in northern and southern China and to document the most important arbovirus vectors found in the study area, the evidence generated here is critical for early prevention and control inter ventions.
