Molecular hydrogen attenuates fatty acid uptake and lipid accumulation through downregulating CD36 expression in HepG2 cells

MHID-9934004PMID: 234482062013Medical Gas Research

Akio Iio, Mikako Ito, Tomohiro Itoh, Riyako Terazawa, Yasunori Fujita, Yoshinori Nozawa, et al.

Background: There is accumulating evidence that obesity is closely associated with an impaired free fatty acid metabolism as well as with insulin resistance and inflammation. Excessive fatty acid uptake mediated by fatty acid translocase CD36 plays an important role in hepatic steatosis. Molecular hydrogen has been shown to attenuate oxidative stress and improve lipid, glucose and energy metabolis

Anti-obesity Effect of Alkaline Reduced Water in High Fat-Fed Obese Mice

MHID-3385882PMID: 238115542013Biological & Pharmaceutical Bulletin

Rosa Mistica Coles Ignacio, Tae-Young Kang, Cheol-Su Kim, Soo-Ki Kim, Young-Chul Yang, Joon-Hyung Sohn, et al.

Whether or not alkaline reduced water (ARW) has a positive effect on obesity is unclear. This study aims to prove the positive effect of ARW in high-fat (HF) diet-induced obesity (DIO) in C57BL/6 mice model. Toward this, obesity was induced by feeding the C57BL/6 male mice with high-fat diet (w/w 45% fat) for 12 weeks. Thereafter, the animals were administered with either ARW or tap water. Next, t

Heme oxygenase-1 mediates the anti-inflammatory effect of molecular hydrogen in LPS-stimulated RAW 264.7 macrophages

MHID-1519950PMID: 241487942013International Journal of Surgery

Hong-Guang Chen, Ke-Liang Xie, Huan-Zhi Han, Wei-Na Wang, Da-Quan Liu, Guo-Lin Wang, et al.

Background: Molecular hydrogen (H2) as a new medical gas has an anti-inflammatory effect.

The objective of this study was to characterize the effects of H 2 -rich water (0.9–1.0 l/day) on the content, composition, and biological activities of serum lipoproteins on 20 patients with potential metabolic syn- drome. Serum analysis showed that consumption of H 2

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. The therapeutic goal is to control the systemic inflammation to obtain not only the remission of symptoms, but also improve general state of health. Alth

Ren J, Luo Z, Tian F, Wang Q, Li K, Wang C.

Background: Currently, little evidence exists to support whether the therapeutic approaches for treating ordinary acute pancreatitis (AP) are effective in trauma-induced pancreatitis. Hydrogen-rich (H2) saline is an antioxidant treatment capable of ameliorating the severity of L-arginine-induced AP. In this study, we attempted to validate its protective role against traumatic pancreatitis (TP). M

Background: Mitochondria are the major source of oxidative stress. Acute oxidative stress causes serious damage to tissues, and persistent oxidative stress is one of the causes of many common diseases, cancer and the aging process; however, there has been little success in developing an effective antioxidant with no side effect. We have reported that molecular hydrogen has potential as an effectiv

Chuai Y, Gao F, Li B, Zhao L, Qian L, Cao F, et al.

Our recent studies suggest that H2 (hydrogen) has a potential as a novel radioprotector without known toxic side effects. The present study was designed to examine the underlying radioprotective mechanism of H2 and its protective role on irradiated germ cells. Produced by the Fenton reaction and radiolysis of H2O, hydroxyl radicals (•OH) were identified as the free radical species that were reduce

MHID-89507332012Medical Science Monitor

Yanyong Yang, Bailong Li, Cong Liu, Yunhai Chuai, Jixiao Lei, Fu Gao, et al.

Background: Radiation often causes depletion of immunocytes in tissues and blood, which results in immuno suppression. Molecular hydrogen (H2) has been shown in recent studies to have potential as a safe and effective radioprotective agent through scavenging free radicals. This study was designed to test the hypothesis that H2 could protect immunocytes from ionizing radiation (IR). Material/Metho

MHID-7718760PMID: 225374652012Free radical research

Chuai Y, Qian L, Sun X, Cai J.

Molecular hydrogen (dihydrogen, H(2)) acts as a therapeutic antioxidant by selectively reducing hydroxyl radicals (•OH) and peroxynitrite (ONOO-). It has been well-known that ionising radiation (IR) causes oxidative damage and consequent apoptosis mainly due to the production of •OH that follows radiolysis of H(2)O. Our department reported the protective effect of H(2) in irradiated cells and mice

Acute lung injury (ALI) is still a leading cause of morbidity and mortality in critically ill patients. Recently, our and other studies have found that hydrogen gas (H2) treatment can ameliorate the lung injury induced by sepsis, ventilator, hyperoxia, and ischemia-reperfusion. However, the molecular mechanisms by which H2 ameliorates lung injury remain unclear. In the current study, we investigat

Background: Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by the destruction of bone and cartilage. Although its etiology is unknown, the hydroxyl radical has been suggested to be involved in the pathogenesis of RA. Recently, molecular hydrogen (H2) was demonstrated to be a selective scavenger for the hydroxyl radical. Also, the method to prepare water containing extrem
