RNA-Seq Reveals the Mechanism of Pyroptosis Induced by Oxygen-Enriched IR780 Nanobubbles-Mediated Sono-Photodynamic Therapy.

Background: Sono-photodynamic therapy (SPDT), the combination of sonodynamic therapy (SDT) and photodynamic therapy (PDT), is a promising tumor treatment method. However, the hypoxic tumor microenvironment greatly compromises the efficacy of SPDT. Pyroptosis, a new type of programmed cell death, is mainly induced by some chemotherapeutic drugs in the current research, and rarely by SPDT.

Nanobubble-mediated co-delivery of siTRIM37 and IR780 for gene and sonodynamic combination therapy against triple negative breast cancer.

Gene therapy often fails due to enzyme degradation and low transfection efficiency, and single gene therapy usually cannot completely kill tumor cells. Several studies have reported that tripartite motif-containing protein 37 (TRIM37) plays a significant role in promoting the occurrence and development of triple negative breast cancer (TNBC). Herein, we constructed siTRIM37 and IR780 co-loaded nanobubbles (NBs) to achieve the combination of gene therapy and sonodynamic therapy (SDT) against TNBC.

Design and Control of an Upper Limb Bionic Exoskeleton Rehabilitation Device Based on Tensegrity Structure.

Upper limb exoskeleton rehabilitation devices can improve the quality of rehabilitation and relieve the pressure of rehabilitation medical treatment, which is a research hotspot in the field of medical robots. Aiming at the problems such as large volume, high cost, low comfort, and difficulty in promotion of traditional exoskeleton rehabilitation devices, and considering the lightweight, discontinuous, high flexibility, and high biomimetic characteristics of tensegrity structure, we designed an upper limb bionic exoskeleton rehabilitation device based on tensegrity structure. First, this article uses mapping methods to establish a mapping model for upper limb exoskeletons based on the tensegrity structure and designs the overall structure of upper limb exoskeletons based on the mapping model.

The changes of IgE levels in type 2 inflammatory diseases after treatment of dupilumab: a systematic review and meta-analysis.

Background: Dupilumab is approved for multiple type 2 inflammatory diseases. In the treatment procedure, the changes of IgE levels need further analysis. We evaluated the changes of IgE levels through meta-analysis, aiming to provide a more comprehensive result.

Neutral Per- and Polyfluoroalkyl Substances, Butyl Carbitol, and Organic Corrosion Inhibitors in Aqueous Film-Forming Foams: Implications for Vapor Intrusion and the Environment.

Per- and polyfluoroalkyl substances (PFAS), butyl carbitol, and corrosion inhibitors are components of aqueous film-forming foams (AFFFs). Volatile (neutral) fluorotelomerization (FT)- and electrochemical fluorination (ECF)-based PFAS, butyl carbitol, and organic corrosion inhibitors were quantified in 39 military specification (MilSpec), non-MilSpec, and alcohol resistant-AFFF concentrates (undiluted) from 1974 to 2010. Fluorotelomer alcohols were found only in FT-based AFFFs and -methyl- and -ethyl-perfluoroalkyl sulfonamides, and sulfonamido ethanols were found only in ECF-based AFFFs.

Medical Care at California Wildfire Incident Base Camps.

Objective: The California Emergency Medical Services Authority manages and deploys California Medical Assistance Teams (CAL-MAT) to disaster medical incidents in the state. This analysis reviews diagnoses for ambulatory medical visits at multiple wildland fire incident base camp field sites in California during the 2020 fire season.

Methods: Clinical data without personal health information were extracted retrospectively from patient care records from all patients seen by a provider.

Remodeling of the tumor microenvironment using an engineered oncolytic vaccinia virus improves PD-L1 inhibition outcomes.

Immune checkpoint inhibitor (ICI) immunotherapies have vastly improved therapeutic outcomes for patients with certain cancer types, but these responses only manifest in a small percentage of all cancer patients. The goal of the present study was to improve checkpoint therapy efficacy by utilizing an engineered vaccinia virus to improve the trafficking of lymphocytes to the tumor, given that such lymphocyte trafficking is positively correlated with patient checkpoint inhibitor response rates. We developed an oncolytic vaccinia virus (OVV) platform expressing manganese superoxide dismutase (MnSOD) for use as both a monotherapy and together with anti-PD-L1.

Procyanidin B2 protects against d-galactose-induced mimetic aging in mice: Metabolites and microbiome analysis.

To elucidate the possible mechanisms for the preventive effect of procyanidin B2 on aging, a combined analysis of metabolic profile and gut microbiome was carried out in the present study. The mimetic aged mice induced by d-galactose injection (500 mg/kg, sc daily), and the preventive group was fed with the diet plus 0.2% procyanidin B2.
