Introduction: Oral health management is often difficult in patients after surgical tumor resection and/or radiotherapy due to defects, bulky flaps, limitation of tongue movement, and trismus. In addition, patients who have undergone radiotherapy have serious disabilities such as oral mucositis, mucosal weakening, soft tissue fibrosis, salivary gland disorder, and osteoradionecrosis. Dental hygienists must understand the characteristics of patients after surgical tumor resection and/or radiotherapy. In this report, the oral health management of three patients after maxillectomy, mandibulectomy, and radiotherapy was shown. Case Description: Case 1: A 53-year-old male patient visited our clinic after chemotherapy, radiotherapy, and partial maxillectomy for cancer of the right maxillary gingiva. Case 2: A 65-year-old male patient visited our clinic after radiotherapy for a right-sided tongue cancer, partial mandibulectomy of the right tongue to the oropharynx, a right-sided segmental mandibulectomy and a speech aid and a mandibular prosthesis were provided. Case 3: A 36-year-old female visited our clinic for radiotherapy for left-sided tongue cancer. Dental hygienists provided oral health management to the patients. In oral health management, it was suggested that intervention before cancer treatment, oral hygiene instructions tailored to patients’ symptoms, and frequent professional care are important. Conclusion: Oral health management by dental hygienists is extremely important for patients undergoing maxillofacial cancer treatment to maintain their quality of life in the long term.

Anti-Obesity Effects of Dietary d-Allulose and Medium-Chain Triglycerides in High-Fat Diet-Fed Rats

引用

Food and Nutrition Sciences 2024年第8期15卷 701-710页

作者： Tatsuhiro Matsuo Chihiro Yokoyama Takako Yamada Tetsuo iida Susumu Mochizuki Akihide Yoshihara Kazuya Akimitsu Faculty of Agriculture Kagawa University Miki-cho Japan Research and Development Matsutani Chemical Industry Co. Ltd. Itami Japan

d-Allulose, a rare sugar, exerts anti-obesity effects by inhibiting hepatic lipogenesis and promoting energy expenditure. Medium-chain triglycerides (MCTs) consist of three medium-chain fatty acids connected by glycerol. MCTs have been extensively investigated for their ability to reduce body fat accumulation. We previously investigated the anti-obesity effects of a combination of dietary d-allulose and MCT (5% - 13%) in rats;however, we could not confirm the anti-obesity effects of MCT or observed synergetic effects between d-allulose and MCT on body fat loss. We speculated that our previous studies were influenced by the excessive amount of MCT in the diets. Therefore, in this study, we aimed to investigate the anti-obesity effects of the simultaneous intake of d-allulose and MCT in rats fed an obesity-inducing high-fat diet with a low amount of MCTs (2%). Thirty-two male Wistar rats (3-week-old) were randomly divided into four groups: control, d-allulose, MCT, and d-allulose + MCT groups. Rats in each group were fed ad libitum on a control (no d-Allulose or MCT), 5% d-allulose, 2% MCT, or 5% d-allulose + 2% MCT diets for 16 weeks. Abdominal adipose tissue weights were significantly lower in the d-allulose diet group than in the control group, whereas no differences were observed between results of the MCT-supplemented groups. The total body fat mass was significantly lower in the d-allulose and MCT diet groups than in the control group, but no differences were observed between the MCT-supplemented groups. These results suggested that anti-obesity effects of dietary d-allulose were observed, and the effects of dietary MCTs were weaker than those of d-allulose. Moreover, we confirmed the interaction between dietary d-allulose and MCT on indicators of obesity. Interestingly, their effects were not synergistic, as MCT supplementation offset the anti-obesity effects of dietary d-allulose. However, the specific mechanisms underlying those effects remain unknown, warran

Negative refraction of deep water waves through water channel network

引用

Journal of Hydrodynamics 2019年第4期31卷 840-847页

作者： Takahito iida Masashi Kashiwagi Department of Naval Architecture and Ocean Engineering Osaka University Suita Osaka 5650871 Japan Research Fellow of Japan Society for the Promotion of Science Chiyoda-ku Tokyo 1020083 Japan

A design method of a negative refractive index for free surface water waves in deep water is presented. To obtain a condition of a negative index, an analogy between water waves in a water channel and electric waves in an electric circuit is employed. An analytical solution of waves around a periodic array of rectangular columns is obtained by a circuit analysis. Attention is not focused on columns but a space among columns, and then the space is regarded as the water channel. Therefore, the circuit analysis can be applied to water waves. One channel is treated as a unit structure and a number of channels are periodically cascaded as a network. The negative refraction and backward waves by a network of the water channels are shown. Since the negative refraction might occur even around simple periodic structures, it is meaningful to understand wave phenomenon around offshore structures and develop innovative technology.
