The Effect of Digital Mental Health Literacy Interventions on Mental Health: Systematic Review and Meta-Analysis.

Background: Accelerated by technological advancements and the recent global pandemic, there is burgeoning interest in digital mental health literacy (DMHL) interventions that can positively affect mental health. However, existing work remains inconclusive regarding the effectiveness of DMHL interventions.

Objective: This systematic review and meta-analysis investigated the components and modes of DMHL interventions, their moderating factors, and their long-term impacts on mental health literacy and mental health.

Kruppel-family zinc finger proteins as emerging epigenetic biomarkers in head and neck squamous cell carcinoma.

Background: Krüppel-type zinc finger protein genes located on chromosome 19q13 are aberrantly hypermethylated with high frequency in all anatomic sub-sites of head and neck cancers as well as other epithelial tumours resulting in decreased expression.

Methods: We examined prognostic significance of ZNF154 and ZNF132 expression and DNA methylation in independent patient cohort of about 500 head and neck cancer patients in the Cancer Genome Atlas (TCGA). We also overexpressed these genes in HEK-293 cells, as well as the oral cancer cell line UM-SCC-1.

Cardiac expression of ryanodine receptor subtype 3; a strategic component in the intracellular Ca release system of Purkinje fibers in large mammalian heart.

Background: Three distinct Ca release channels were identified in dog P-cells: the ryanodine receptor subtype 2 (RyR2) was detected throughout the cell, while the ryanodine receptor subtype 3 (RyR3) and inositol phosphate sensitive Ca release channel (InsP3R) were found in the cell periphery. How each of these channels contributes to the Ca cycling of P-cells is unclear. Recent modeling of Ca mobilization in P-cells suggested that Ca sensitivity of Cainduced Carelease (CICR) was larger at the P-cell periphery.

Effects of chronic in-vivo treatments with protease-activated receptor 2 agonist on endothelium function and blood pressures in mice.

Short-term treatments with protease-activated receptor 2-activating peptides (PAR2-AP) induce endothelium-dependent vasodilation and decrease blood pressure. In this study, we tested the effect of chronic in-vivo treatment with PAR2-AP on the blood pressure and endothelium function of mice. Male PAR2 wild-type (WT) and par2-deficient (KO) mice received subcutaneous infusions of either saline, low (PAR2-LD), or high (PAR2-HD) doses of 2-furoyl-LIGRLO-amide for 1 or 2 weeks.

Protection of protease-activated receptor 2 mediated vasodilatation against angiotensin II-induced vascular dysfunction in mice.

Background: Under conditions of cardiovascular dysfunction, protease-activated receptor 2 (PAR2) agonists maintain vasodilatation activity, which has been attributed to increased cyclooxygenase-2, nitric oxide synthase and calcium-activated potassium channel (SK3.1) activities. Protease-activated receptor 2 agonist mediated vasodilatation is unknown under conditions of dysfunction caused by angiotensin II.

Preserved arterial vasodilatation via endothelial protease-activated receptor-2 in obese type 2 diabetic mice.

Background And Purpose: In non-obese diabetic animals, protease-activated receptor-2 (PAR2) agonists are more effective vasodilators, which is attributed to increased COX-2 and endothelial NOS (eNOS) activities. Under conditions of diabetes and obesity, the effectiveness of PAR2 agonists is unknown. We compared the vasodilator responses of small calibre mesenteric arteries from obese diabetic B6.

Sesquiterpene dialdehydes inhibit MSU crystal-induced superoxide production by infiltrating neutrophils in an in vivo model of gouty inflammation.

A hallmark feature of monosodium urate (MSU) crystal-induced inflammation in gouty arthritis is the infiltration of activated neutrophils into the joint. Therefore inhibition of neutrophil superoxide production is a rational target for treating inflammation in gout. The natural product polygodial and related sesquiterpene dialdehyde analogs were tested in vitro and in vivo for their ability to inhibit neutrophil infiltration and superoxide production in response to MSU crystal stimulation.

Synthesis and anti-inflammatory structure-activity relationships of thiazine-quinoline-quinones: inhibitors of the neutrophil respiratory burst in a model of acute gouty arthritis.

Sixteen new thiazine-quinoline-quinones have been synthesised, plus one bicyclic analogue. These compounds inhibited neutrophil superoxide production in vitro with IC(50)s as low 60 nM. Compounds with high in vitro anti-inflammatory activity were also tested in a mouse model of acute inflammation.

An antiproliferative bis-prenylated quinone from the New Zealand brown alga Perithalia capillaris.

Bioactivity-directed isolation work on the endemic New Zealand brown alga Perithalia capillaris, seeking anti-inflammatory compounds, led to a new bis-prenylated quinone ( 4). This compound inhibited superoxide production by human neutrophils in vitro (IC 50 2.1 microM), but was more potent at inhibiting proliferation of HL60 cells (IC 50 0.

Anti-inflammatory thiazine alkaloids isolated from the New Zealand ascidian Aplidium sp.: inhibitors of the neutrophil respiratory burst in a model of gouty arthritis.

Ascidiathiazones A (3) and B (4), two new tricyclic thiazine-containing quinolinequinone alkaloids, were isolated from the New Zealand ascidian Aplidium species. Both compounds inhibited the in vitro production of superoxide by PMA-stimulated human neutrophils in a dose-dependent manner with IC50 1.55 +/- 0.

E/Z-rubrolide O, an anti-inflammatory halogenated furanone from the New Zealand ascidian Synoicum n. sp.

Bioassay-directed fractionation of extracts of a Synoicum n. sp. ascidian from New Zealand led to the isolation of the principal anti-inflammatory component, which was identified by spectroscopic methods as a new member of the rubrolide family, rubrolide O (1), existing as a mixture of E/Z isomers.

Anti-inflammatory sesquiterpene-quinones from the New Zealand sponge Dysidea cf. cristagalli.

The inhibition of superoxide production by human neutrophils has been used to screen New Zealand's unique biota for anti-inflammatory natural products. Bioactivity-directed isolation on an extract of the sponge Dysidea cf. cristagalli led to a new sesquiterpene-quinone (4) with anti-inflammatory activity, plus acetylated hydroquinone (3).
