Editorial comments

This special issue includes two articles written by the winners of Young Investigator Award of the 26th Japanese Maillard Reaction Society (JMARS) meeting, Drs. Kyoko Noda (Oral) and Ai Harashima (Poster). The JAMRS annual meeting was held on November 11-12, 2016 at International Congress Center Epochal Tsukuba, Tsukuba, Ibaraki.

Dr. Kyoko Noda at Department of Nutrition and Food Science, Ochanomizu University, Tokyo, received the best oral presentation award on her food science research on “Novel Maillard Yellowish Pigments Having Pyrrolothiazole or Pyrrolooxazole Skeleton”. She identified three novel yellowish Maillard pigments having pyrrolothiazole or pyrrolooxazole skeleton, which may be specific in the Maillard reaction

Dr. Ai Harashima at Department of Biochemistry and Molecular Vascular Biology, Kanazawa University Graduate School of Medical Sciences, Kanazawa, got the best poster presentation award on her medical science research on “Perception of pathogenic bacteria by pattern recognition receptor RAGE in the frontline”. She demonstrated that the critical role of RAGE in the early innate immune responses to invading pathogens by sensing microorganism.

These young and active researchers will open a new avenue to advance the science for Maillard reaction. I deeply thank their great contributions to the IMARS Highlights. The IMARS Highlights editors always look forward to submission of your articles, comments to any kinds of issues published in IMARS Highlights and other glycation-related issues in the field of food and medical sciences.

Editorial Comment to the March 2017 Issue of IMARS Highlights

Editorial comments

In this issue, we selected two articles highlighted the link between stress signal and glycation.

The first article written by Dr. Christos Adamopoulos and Prof. Christina Piperi, Department of Biological Chemistry, Medical School, National and Kapodistrian University of Athens, Greece, summarized that high-AGE content diet causes endoplasmic reticulum (ER) dysfunction, referred to as ER stress, in brain, kidney, liver and pancreas, and thereby induces stress signal, unfolded protein response (UPR). The UPR pathway is known to regulate not only protein homeostasis, but also glucose and lipid metabolism. Thus, dietary AGEs may contribute to development and progression of metabolic diseases via the UPR activation that alters metabolic status in metabolic organs.

The second article written by Prof. Chih-Kang Chiang, Graduate Institute of Toxicology, College of Medicine, National Taiwan University, Taiwan, demonstrated the impact of pathogenic effect of AGEs on mesangial cell injury, which is one of the major phenotypic changes of diabetic nephropathy. AGEs induce ER stress in mesangial cells, and subsequently decrease mesangial cell viability associated with induction of apoptosis. Importantly, such AGEs-ER stress-mesangial cell apoptosis axis is regulated by autophagy. These findings suggest that the AGEs-induced autophagy mediated by ER stress may be a therapeutic target for prevention of mesangial cell damage and subsequent progression of diabetic nephropathy.

I deeply thank their great contributions to the IMARS Highlights. The IMARS Highlights editors always look forward to submission of your articles, comments to any kinds of issues published in IMARS Highlights and other glycation-related issues in the field of food and medical sciences.

Editorial Comment to the January 2017 Issue of IMARS Highlights

IMARS HighlightEditorial comments

IMARS committees would like to celebrate a very happy and successful 2017 to all the members of IMARS. Our society will keep moving forward and we expect your continuous contribution to the IMARS Highlights. I, as an editor of the IMARS Highlights, promise that this on-line journal will provide you useful and exciting information about glycation research in different fields, from food science to medicine, to enjoy international and different-field exchange, and enhance collaboration.

In the New Year issue of this year, we invited Prof. Yuri Nomi at Niigata University of Pharmacy and Applied Life Sciences, Niigata, Japan. Her article, entitled “Useful and accurate method for Simultaneous Quantitation of Advanced Glycation End Products by Liquid Chromatography-Tandem Mass Spectrometry without Ion-Pair Reagents and Derivatization”, summarizes a novel simple and sensitive method for the simultaneous determination of various AGEs by LC-MS/MS. The LC-MS/MS method revealed that materials, processing condition, and protein content clearly affects the levels of free AGEs in food.

The second article, entitled “The effect of molecular crowding on Maillard reaction”, was written by Dr. Edoardo Capuano at Wageningen University, Wageningen, the Netherlands. This article focuses on the link between molecular crowding and Maillard reaction in the field of food science.

I deeply thank their great contributions to the IMARS Highlights. The IMARS Highlights editors always look forward to submission of your articles, comments to any kinds of issues published in IMARS Highlights and other glycation-related issues in the field of food and medical sciences.

Editorial Comment to the November 2016 Issue of IMARS Highlights

Editorial Comment

In this issue, we publish two articles of the field of food science of glycation research.

The review article written by Prof. Frédéric J Tessier, Lille Inflammation Research International Center, Lille University, France, focuses on the benefit of butter consumption in healthy life style. Over intake of saturated fatty acids, but not unsaturated fatty acids, is a risk factor of cardiovascular disease.  However, unsaturated fatty acids are structurally unstable and are processed to toxic compounds under the certain conditions, indicating the beneficial properties of saturated fatty acids rather than unsaturated fatty acids in healthy food intake.
The second updated article written by Dr. Jianlei Liu and Prof. Hao Jing, China Agricultural University, China, demonstrated the impact of glycation on heat-induced protein aggregation. The thermal denaturation of food proteins may be lowered by glycation.

I deeply thank their great contributions to the IMARS Highlights.The IMARS Highlights editors always look forward to submission of your articles, comments to any kinds of issues published in IMARS Highlights and other glycation-related issues in the field of food and medical sciences.
