ROS-responsive supramolecular antimicrobial peptides-based nanoprodrugs for cervical cancer therapy.

Although antimicrobial peptides (AMPs) as a promising natural drugs can efficiently inhibit cervical cancer, poor bioavailability, low tumor selectivity, and non-selective toxicity still hinder its further application in vivo. In order to effectively address these challenges, we have developed a reactive oxygen species (ROS)-responsive targeting nanoprodrug designed for selective therapy of cervical cancer. Such nanoprodrugs (CEC-OxbCD) are fabricated by the supramolecular self-assembly of the modified β-cyclodextrin (β-CD) and AMPs.

3D hand pose and mesh estimation via a generic Topology-aware Transformer model.

In Human-Robot Interaction (HRI), accurate 3D hand pose and mesh estimation hold critical importance. However, inferring reasonable and accurate poses in severe self-occlusion and high self-similarity remains an inherent challenge. In order to alleviate the ambiguity caused by invisible and similar joints during HRI, we propose a new Topology-aware Transformer network named HandGCNFormer with depth image as input, incorporating prior knowledge of hand kinematic topology into the network while modeling long-range contextual information.

Nucleic Acid Prevalence of Zoonotic in Humans, Animals and Questing Ticks, a Systematic Review and Meta-Analysis.

Zoonotic infections are an emerging public health threat globally. The geographical distribution, animal reservoirs and tick vectors vary greatly across species, and estimations of prevalence reported in works within the literature are also quite different. Better prevalence estimates and identification of moderators are needed to understand the global transmission risk of different zoonotic species, and to provide crucial background information for the diagnosis, treatment and control of zoonotic babesiosis.

LncRNA SNHG7 promotes non-small cell lung cancer progression and cisplatin resistance by inducing autophagic activity.

Background: Cisplatin (DDP) is among the most widely used chemotherapeutic drugs for non-small cell lung cancer (NSCLC), yet the frequent emergence of chemoresistance serves as a major barrier to the treatment of this tumor type. Long non-coding RNAs (lncRNAs) have recently been shown to influence the ability of cells to resist particular chemotherapy drugs. The present study was developed to explore the role of the lncRNA SNHG7 as a regulator of NSCLC cell chemosensitivity.
