Tea tree oil nanoemulsion targets AgrA protein potentiates amoxicillin efficacy against methicillin-resistant Staphylococcus aureus.

The excessive utilization of antibiotics gives rise to the development of bacterial resistance, the deterioration of animal immune functions, the increase in mortality rates, and the undermining of human immunity. Therefore, there is an urgent necessity to explore new antimicrobial agents or alternatives to tackle bacterial resistance. We investigated tea tree oil (TTO), a pure natural plant essential oil extracted from Melaleuca leaves, which exerted efficient antibacterial activities.

Multifunctional hydrogel based on polyvinyl alcohol/chitosan/metal polyphenols for facilitating acute and infected wound healing.

Bacterial-infected wounds could cause delayed wound healing due to increased inflammation, especially wounds infected by drug-resistant bacteria remain a major clinical problem. However, traditional treatment strategies were gradually losing efficacy, such as the abuse of antibiotics leading to enhanced bacterial resistance. Therefore, there was an urgent need to develop an antibiotic-free multifunctional dressing for bacterially infected wound healing.

Chitosan-coated PLGA microemulsion loaded with tannic acid against Escherichia coli in vitro and in vivo.

Consequently, the development of a versatile hydrogel dressing possessing robust bioactivity becomes imperative, as it holds the potential to expedite wound healing and yield enhanced clinical therapeutic outcomes. In this context, the present study involves the formulation of an injectable multifunctional hydrogel utilizing laponite (LAP) and lactoferrin (LF) as foundational components and loaded with eugenol (EG).

Eugenol Possesses Colitis Protective Effects: Impacts on the TLR4/MyD88/NF-[Formula: see text]B Pathway, Intestinal Epithelial Barrier, and Macrophage Polarization.

Eugenol (EU) has been shown to ameliorate experimental colitis due to its anti-oxidant and anti-inflammatory bioactivities. In this study, DSS-induced acute colitis was established and applied to clarify the regulation efficacy of EU on intestinal barrier impairment and macrophage polarization imbalance along with the inflammatory response. Besides, the adjusting effect of EU on macrophages was further investigated The results confirmed that EU intervention alleviated DSS-induced colitis through methods such as restraining weight loss and colonic shortening and decreasing DAI scores.

Polysaccharide from Koidz Binding with Zinc Oxide Nanoparticles as a Novel Mucosal Immune Adjuvant for H9N2 Inactivated Vaccine.

H9N2 avian influenza poses a significant public health risk, necessitating effective vaccines for mass immunization. Oral inactivated vaccines offer advantages like the ease of administration, but their efficacy often requires enhancement through mucosal adjuvants. In a previous study, we established a novel complex of polysaccharide from Koidz binding with zinc oxide nanoparticles (AMP-ZnONPs) and preliminarily demonstrated its immune-enhancing function.

Association between cardiovascular health and abdominal aortic calcification: Analyses of NHANES 2013-2014.

Background: Abdominal aortic calcification (AAC) is closely connected to cardiovascular disease. We aimed to measure the association between cardiovascular health (CVH) levels, assessed by the Life's Essential 8 (LE8) score, and AAC within a nationally representative sample of the US.

Methods: The National Health and Nutrition Examination Survey 2013-2014 participants were chosen for this cross-sectional investigation.

Mucosal immune responses and protective efficacy elicited by oral administration AMP-ZnONPs-adjuvanted inactivated H9N2 virus in chickens.

The avian influenza virus is infected through the mucosal route, thus mucosal barrier defense is very important. While the inactivated H9N2 vaccine cannot achieve sufficient mucosal immunity, adjuvants are needed to induce mucosal and systemic immunity to prevent poultry from H9N2 influenza virus infection. Our previous study found that polysaccharide from Atractylodes macrocephala Koidz binding with zinc oxide nanoparticles (AMP-ZnONPs) had immune-enhancing effects in vitro.

The inhibition effect of caffeic acid on NOX/ROS-dependent macrophages M1-like polarization contributes to relieve the LPS-induced mice mastitis.

The mammary gland is an adipose tissue containing not only adipocytes but also epithelial, endothelial, and immune cells. Epithelial cells and macrophages, as the integral components of the immune system, are on the front line of defense against infection. Our preliminary work proved that caffeic acid (CA) can effectively inhibit the inflammatory cascade of bovine mammary epithelial cells (BMEC) induced by lipopolysaccharide (LPS) and maintain cellular integrity and viability.

Threshold effects and inflection points of flavonoid intake in dietary anti-inflammatory effects: Evidence from the NHANES.

Flavonoids have been shown to be beneficial in a variety of inflammatory and metabolic diseases because of their anti-inflammatory and antioxidant properties. However, previous epidemiological studies have only demonstrated a negative correlation between flavonoid intake on inflammatory markers, and the optimal intake of dietary flavonoids and subclasses in terms of dietary anti-inflammatory efficacy remains undetermined. This study was based on 3 cycles (2007-2010, 2017-2018) of the National Health and Nutrition Examination Survey and the corresponding expanded flavonoid database.

Associations between cadmium exposure and whole-body aging: mediation analysis in the NHANES.

Introduction: Even though cadmium (Cd) exposure and cellular senescence (telomere length) have been linked in previous studies, composite molecular aging biomarkers are more significant and reliable factors to consider when examining the connection between metal exposure and health outcomes. The purpose of this research was to assess the association between urinary cadmium (U-Cd) and whole-body aging (phenotypic age).

Methods: Phenotypic age was calculated from chronological age and 9 molecular biomarkers.

Paeonol accelerates skin wound healing by regulating macrophage polarization and inflammation in diabetic rats.

Diabetic ulcer is usually seen in people with uncontrolled blood sugar. Reportedly, many factors such as impaired glucose metabolism, and macrovascular and microvascular diseases caused angiogenesis disorders and delayed the healing of diabetic ulcers, thus affecting the body's metabolism, nutrition, and immune function. This study aimed to explore the effect of paeonol on skin wound healing in diabetic rats and the related mechanism.
