水の硬度が牛肉の煮込みに及ぼす影響
The purpose of this study was to investigate the effects of water hardness on the physical properties of boiled beef and to clarify whether hard water is suitable for stewed dishes. Using sensory evaluation, we found that beef boiled in hard water(Ca : 300 mg/L)was evaluated more highly than beef boiled in soft water(Ca : 50 mg/L); this was true of both the odor and taste of the beef.When beef was boiled in hard water, the protein on the surface of the beef rapidly solidified, preventing the release of components from the inside even when heated for a long time.These results suggest that hard water is more suitable for beef stew than soft water.原著論
iBTA-Induced Biotube® Blood Vessels: 2020 Update
Blood access is a lifeline for dialysis patients. However, serious problems such as stenosis or obstruction of access blood vessels, which are life-threatening conditions in daily clinical practice, still remain. One of the most promising candidates for solving these problems may be Biotube blood vessels. More than 20 years have passed since the development of in-body tissue architecture (iBTA), a technology for preparing tissues for autologous implantation in patients. The tissues obtained by iBTA do not elicit immunological rejection, which is one of the ultimate goals of regenerative medical engineering; however, their practical applications were quite challenging. The seemingly unorthodox iBTA concepts that do not follow the current pre-established medical system may not be readily accepted in general medicine. In contrast, there are many diseases that cannot be adequately addressed even with the latest and most advanced medical technology. However, iBTA may be able to save patients with serious diseases. It is natural that the development of high-risk medical devices that do not fit the corporate logic would be avoided. In order to actively treat such largely unattached diseases, we started Biotube Co., Ltd. with an aim to contribute to society. Biotubes induced by iBTA are collagenous tubular tissues prepared in the patient’s body for autologous implantation. The application of Biotubes as tissues for vascular implantation has been studied for many years. Biotubes may have excellent potential as small-diameter artificial blood vessels, one of the most difficult to clinically achieve. Their possibility is currently being confirmed in preclinical tests. Biotubes may save hundreds of thousands of patients worldwide annually from amputation. In addition, we aim to eliminate the recuring access vascular problems in millions of dialysis patients. This study provides an update on the current development status and future possibilities of Biotubes and their preparation molds, Biotube Makers
