The weaker soft tissue integration around implants compared to natural teeth poses a substantial challenge to the long-term success of implants. To enhance soft tissue integration, we develop an on-demand and long-lasting H2-releasing implant to achieve precise sequential regulation of the soft tissue integration through immunomodulation and pro-remodeling coupling. In the inflammatory phase, the

This study was carried out in an experimental study design with experimental and control groups to investigate the effect of hydrogen-enriched water (HRW) on healing in excisional full-layer skin wounds. The rats were divided into diabetic group (n = 20) and non-diabetic group (n = 18) (n = 38). Diabetic group was divided into three groups as diabetic wound (DC), diabetic wound saline (DS), and di

Molecular hydrogen is a colorless, tasteless, biologically active small-molecule gas with reducing properties, demonstrating therapeutic and preventive effects across various human systems. Its mechanisms of action include selective antioxidation, anti- inflammatory effects, apoptosis inhibition, and the regulation of gene expression and signaling pathways. In the skin, molecular hydrogen reduces

The aim of the review was to examine the main characteristics of hydrogen ion metabolism and its hemostatic function in the human body. For diagnostic purposes, molecular hydrogen (H2) is considered a biological marker. The results of the analysis of therapeutic programs for the clinical use of hydrogen are presented. The use of H2 as a drug in the treatment of more than 170 diseases is also discu

Radiation dermatitis (RD) is a common side effect in patients receiving radiotherapy. Currently, clinical skincare approaches for acute RD vary widely among institutions and lack consensus. Hydrogen molecules, acting as radioprotective agents by selectively scavenging free radicals, have the potential to protect against RD. In this study, we demonstrate that hydrogen reduces double- strand breaks,

It is a great challenge to effectively eradicate biofilm and cure biofilm-infected diseases because dense extracellular polymeric substance matrix prevents routine antibacterial agents from penetrating into biofilm. H2 is an emerging energy-regulating molecule possessing both high biosafety and high tissue permeability. In this work, we propose a concept of sonocatalytic hydrogen/hole-combined ‘in

High-glucose microenvironment in the diabetic foot ulcer (DFU) causes excessive glycation and induces chronic inflammation, leading to the difficulty of DFU healing. Hydrogen-rich water bath can promote the healing of DFU in clinic by virtue of the anti-inflammatory effect of hydrogen molecules, but the long-term daily soaking counts against the formation of a scab and cannot change the high-glucose

Wound healing is a complex dynamic process involving a large number of biological events. Excessive oxidative stress is a key factor delaying wound healing. Hydrogen is an antioxidant, anti-inflammatory, and antiapoptotic medical gas with safety, effectiveness, and penetrability. However, the effects of local treatment of hydrogen on wound healing and its potential mechanisms remain unclear. In this

The incidence of dry eye disease is increasing worldwide because of the aging population and increasing use of information technology. Dry eye disease manifests as tear-layer instability and inflammation caused by osmotic hypersensitization in tear fluids; however, to our knowledge, no agent that treats both pathologies simultaneously is available.

Molecular hydrogen (H2) is recognized as a gaseous antioxidant, and it is expected to ameliorate various disorders related to oxidative stress and inflammation. However, there are still many unclear points regarding its effectiveness in the skin. Therefore, the purpose of this study was to examine the protective effect of H2 against ultraviolet (UV) irradiation-related stress injury in human epide

Oxidative stress is proven to be critical for the initiation and progression of vitiligo. Molecular hydrogen (H2) possesses potent antioxidant activity and has been shown to protect against various oxidative stresserelated diseases. In this study, we first investigated the effects and mechanisms of H2 in human melanocytes damaged by hydrogen peroxide. We initially found that H2 reduced intracellula

Hydrogen-dissolved water has been shown to improve diverse oxidation stress-related diseases, which drove us to examine effects of hydrogen-rich water on oxidation stress-related skin troubles and lipid-metabolism markers. The purpose of this study is whether the dissolved hydrogen in hydrogen-rich water was kept even after boiling, and whether hydrogen-bath utilization improves cosmetic effects s

Based on the oxidative stress theory, aging derives from the accumulation of oxidized proteins induced by reactive oxygen species (ROS) in the cytoplasm. Hydrogen peroxide (H2O2) elicits ROS that induces skin aging through oxidation of proteins, forming disulfide bridges with cysteine or methionine sulfhydryl groups. Decreased Ca2+ signaling is observed in aged cells, probably secondary to the for

Atopic dermatitis (AD) is a chronically relapsing, pruritic, eczematous skin disorder accompanying al- lergic inflammation. AD is triggered by oxidative stress and immune imbalance. In the present study, we in- vestigated the effect of drinking hydrogen water (HW) on 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis in NC/Nga mice and found that HW ameliorated DNCB-induced AD-like clinical
