Intracellular trafficking of lipid nanoparticles is hindered by cholesterol.

The intracellular trafficking of lipid nanoparticles (LNPs) leading to endosomal escape is critical for delivery efficiency. How components of LNP affect its intracellular trafficking and delivery efficiency remains unknown. Here, we developed a highly sensitive LNP/nucleic acid tracking platform based on streptavidin-biotin-DNA complex and high throughput imaging.

Identifying the healthy places to live in Australia with a new environmental quality health index.

Background: Existing environmental quality indices often fail to account for the varying health impacts of different exposures and exclude socio-economic status indicators (SES).

Objectives: To develop and validate a comprehensive Environmental Quality Health Index (EQHI) that integrates multiple environmental exposures and SES to assess mortality risks across Australia.

Methods: We combined all-cause, cardiovascular, and respiratory mortality data (2016-2019) from 2,180 Statistical Areas Level 2 with annual mean values of 12 environmental exposures, including PM, ozone, temperature, humidity, normalized difference vegetation index, night light, road and building density, and socioeconomic status.

Global, regional, and national mortality burden attributable to air pollution from landscape fires: a health impact assessment study.

Background: Landscape fire-sourced (LFS) air pollution is an increasing public health concern in the context of climate change. However, little is known about the attributable global, regional, and national mortality burden related to LFS air pollution.

Methods: We calculated country-specific population-weighted average daily and annual LFS fine particulate matter (PM) and surface ozone (O) during 2000-19 from a validated dataset.

Mechanisms of autophagy and their implications in dermatological disorders.

Autophagy is a highly conserved cellular self-digestive process that underlies the maintenance of cellular homeostasis. Autophagy is classified into three types: macrophage, chaperone-mediated autophagy (CMA) and microphagy, which maintain cellular homeostasis through different mechanisms. Altered autophagy regulation affects the progression of various skin diseases, including psoriasis (PA), systemic lupus erythematosus (SLE), vitiligo, atopic dermatitis (AD), alopecia areata (AA) and systemic sclerosis (SSc).

Polycaprolactone/gelatin-QAS/bioglass nanofibres accelerate diabetic chronic wound healing by improving dysfunction of fibroblasts.

Worldwide, more than 25 % of patients with diabetes develop chronic diabetic wounds in their lifetime. Infection and dysfunctional fibroblasts represent two significant etiological factors contributing to impaired wound healing in patients with diabetes. It is therefore evident that the development of wound dressings with both anti-infective and DM fibroblast modulating functions has the potential for clinical applications.

Phenolic Compound Profiles, Antioxidant, and Cytoprotective Activity of Elaeagnus conferta Roxb. Fruit.

In this paper, three varieties of Elaeagnus conferta Roxb fruits prepared by ultrasonic-assisted extraction from a subtropical region southwest of China were utilized as raw materials to investigate their phenolic profiles, antioxidant activities, and protective effects on injured human umbilical vein endothelial cells (HUVECs). The ultra performance liquid chromatography-electrospray ionization tandem mass spectrometry (UPLC-ESI-MS/MS) findings revealed that fifteen substances, including seven phenolic acids, seven flavonoids, and one gallic acid derivative, were discovered. The dihydromyricetin, ellagic acid, gallic acid were the predominant phenolic compounds in all E.

Short-term ozone exposure and cancer mortality in Brazil: A nationwide case-crossover study.

Exposure to ambient ozone (O) is linked to increased mortality risks from various diseases, but epidemiological investigations delving into its potential implications for cancer mortality are limited. We aimed to examine the association between short-term O exposure and site-specific cancer mortality and investigate vulnerable subgroups in Brazil. In total 3,459,826 cancer death records from 5570 Brazilian municipalities between 2000 and 2019, were included.

Association of the High-Sensitivity C-Reactive Protein-to-Albumin Ratio with Carotid Atherosclerotic Plaque: A Community-Based Cohort Study.

Background: The inflammatory response is a pivotal factor in accelerating the progression of atherosclerosis. The high-sensitivity C-reactive protein-to-albumin ratio (CAR) has emerged as a novel marker of systemic inflammation. However, few studies have shown the CAR to be a promising prognostic marker for carotid atherosclerotic disease.

Cancer mortality risk from short-term PM exposure and temporal variations in Brazil.

Although some studies have found that short-term PM exposure is associated with lung cancer deaths, its impact on other cancer sites is unclear. To answer this research question, this time-stratified case-crossover study used individual cancer death data between January 1, 2000, and December 31, 2019, extracted from the Brazilian mortality information system to quantify the associations between short-term PM exposure and cancer mortality from 25 common cancer sites. Daily PM concentration was aggregated at the municipality level as the key exposure.

Floods and cause-specific mortality in the UK: a nested case-control study.

Background: Floods are the most frequent weather-related disaster, causing significant health impacts worldwide. Limited studies have examined the long-term consequences of flooding exposure.

Methods: Flood data were retrieved from the Dartmouth Flood Observatory and linked with health data from 499,487 UK Biobank participants.

Effect of surface viscoelasticity on top jet drops produced by bursting bubbles.

Jet drops resulting from bubble bursting at a liquid surface play a key role in various mass transfer processes across the interface, including sea spray aerosol generation and pathogen transmission. However, the impact of structurally compound interfaces, characterized by complex surface rheology introduced by surface-active contaminants, on the jet drop ejection still remains unclear. Here, we experimentally investigate the influence of surface viscoelasticity on the size and velocity of the top jet drops from surface bubble bursting, examining both pure protein and mixed protein-surfactant solutions.

Discovery of Hepatitis B Virus Surface Antigen Suppressor GS-8873.

Chronic hepatitis B (CHB) virus infection afflicts hundreds of millions of people and causes nearly one million deaths annually. The high levels of circulating viral surface antigen (HBsAg) that characterize CHB may lead to T-cell exhaustion, resulting in an impaired antiviral immune response in the host. Agents that suppress HBsAg could help invigorate immunity toward infected hepatocytes and facilitate a functional cure.

Spatiotemporal characteristics and influencing factors for joint events of air pollution wave and cold wave in China.

Climate change triggered more environmental extremes. The joint events of air pollution wave and cold wave showed higher health risks than independent events, but little evidence is available for the spatiotemporal features of their co-occurrence. To better understand and forecast the joint events, a method framework was developed in this study.

The phosphokinase activity of IRE1ɑ prevents the oxidative stress injury through miR-25/Nox4 pathway after ICH.

Background: Endoplasmic reticulum (ER) stress and oxidative stress are the major pathologies encountered after intracerebral hemorrhage (ICH). Inositol-requiring enzyme-1 alpha (IRE1α) is the most evolutionarily conserved ER stress sensor, which plays a role in monitoring and responding to the accumulation of unfolded/misfolded proteins in the ER lumen. Recent studies have shown that ER stress is profoundly related to oxidative stress in physiological or pathological conditions.
