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

The antioxidant and anti-inflammatory properties of molecular hydrogen (H2) have been explored for their possible health advantages. H2 is the smallest and most basic molecule, and it may easily pass through cell membranes to reach cellular compartments. Research on the health significance of H2 is still in its early stages, and although some studies have yielded encouraging results, further resea

Background: Hydrogen gas (H2) has been shown to be effective in the treatment of various clinical conditions, from acute illnesses to chronic illnesses. However, its clinical indications and the corresponding appropriate hydrogen delivery methods have yet to be determined. This is due to the fact that the pharmacokinetics and pharmacodynamics of hydrogen in each delivery method have not been exper

Molecular hydrogen (H2) has antioxidant, anti-inflammatory, and anti-fibrotic effects. In a rat model simulating pulmonary fibrotic changes induced by monocrotaline-induced pulmonary hypertension (MPH), we had previously explored the impact of inhaled H2 on lung inflammation and blood pressure. In this study, we further focused the biological effects of H2 on mast cells (MCs) and the parameters of

Obstructive sleep apnea (OSA) is a chronic condition characterized by recurrent upper airway collapse during sleep, leading to chronic intermittent hypoxia (CIH) that can cause oxidative stress and chronic inflammation that lead to cardiovascular disease (CVD). Although continuous positive airway pressure (CPAP) treatment is the gold standard for OSA treatment, it has little or no benefit in reduc

Purpose: To examine the effects of hydrogen water on retinal blood flow (RBF) dysregulation in diabetes, we evaluated changes in RBF in response to flicker stimulation and systemic hyperoxia in diabetic mice.
Methods: Twelve type 2 diabetic mice were divided into a group that received non-hydrogen water (n = 6, control group) and the other that received hydrogen-rich water (0.6–0.8 mM) (n = 6, HR

Oxidative stress and chronic inflammation have been implicated in the pathophysiology of metabolic diseases, including diabetes mellitus (DM), metabolic syndrome (MS), fatty liver (FL), atherosclerosis (AS), and obesity. Molecular hydrogen (H2) has long been considered a physiologically inert gas. In the last two decades, accumulating evidence from pre-clinical and clinical studies has indicated th

Cardiovascular disease is the leading cause of mortality worldwide. Excessive oxidative stress and inflammation play an important role in the development and progression of cardiovascular disease. Molecular hydrogen, a small colorless and odorless molecule, is considered harmless in daily life when its concentration is below 4% at room temperature. Owing to the small size of the hydrogen molecule,

Hydrogen-rich water (HW) has been suggested to possess antioxidant properties of value in treatments of lifestyle diseases and for prevention of latent pathologies. To date, the potential benefits of HW against the deleterious effects of excessive salt intake and hypertension have not been investigated. Here, we first examined the effects of HW or HW supplemented with 0.1% ascorbic acid (HWA) on s

Oxidative stress and inflammation are closely related to atherosclerotic cardiovascular disease. It is established that hydrogen has significant protective effects on many diseases as a potential antioxidative and anti-inflammatory agent. The purpose of this study is to evaluate the effect of hydrogen on unstable angina in vitro and in vivo. An atherosclerosis model in vitro was constructed by ox-

A recent clinical study demonstrated that haemodialysis with a dialysate containing hydrogen (H2) improves blood pressure control in end-stage kidney disease. Herein, we examined whether H2 has a salutary effect on hypertension in animal models. We subjected 5/6 nephrectomised rats to inhalation of either H2 (1.3% H2 + 21% O2 + 77.7% N2) or control (21% O2 + 79% N2) gas mixture for 1 h per day. H2

Background: Measurement of the reactive hyperemia index (RHI) using peripheral arterial tonometry (PAT) has shown benefits in the evaluation of vascular endothelial function and prediction of cardiovascular disease prognosis. Thus, it is important to examine the factors that promote the RHI. In this study, we aimed to investigate the effect of molecular hydrogen (H2) on reactive hyperemia-PAT of t

Therapeutic effects of molecular hydrogen for a wide range of disease models and human diseases have been investigated since 2007. A total of 321 original articles have been published from 2007 to June 2015. Most studies have been conducted in Japan, China, and the USA. About three-quarters of the articles show the effects in mice and rats. The number of clinical trials is increasing every year. I

Patients with pulmonary arterial hypertension (PAH) are at higher risk for morbidity and mortality after all types of cardiac surgical procedures. These patients have higher incidences of hemodynamic instability, hypoxemia, and right ventricular dysfunction. Current therapy for PAH has included prostanoids, endothelial receptor antagonists, and phosphodiesterase inhibitors. Although these agents h

Rheumatoid arthritis (RA) is a chronic inflammatory disease in which the progressive destruction of joint causes morbidity. It is also associated with an increased risk of atherosclerosis, which can result in cardiovascular disease and mortality.
