In recording and reproducing skills involving the fingertips, a sensor that measures tactile information of fingertips is important. However, when the sensor covers the finger pad, the inherent sense of touch is compromised. We introduce a new tactile sensor, a pair of a vibration motor and a 6 degrees-of-freedom sensor attached to a fingernail that enables tactile sensing without covering the fingertip.

In this study, we developed a simultaneous extraction method for 19 food additives, including sweeteners, preservatives, and antioxidants, to enhance testing efficiency across a wide range of processed foods. Samples underwent 2 or 4 extractions with acetonitrile containing 0.05 w/v% ascorbic acid palmitate, facilitated by the addition of water, phosphoric acid, magnesium sulfate, and sodium chloride.

A 90-year-old man on maintenance hemodialysis was admitted due to severe symptomatic anemia. Biopsies under esophagogastroduodenoscopy demonstrated that the cause of anemia was intermittent blood oozing from multiple gastric hyperplastic polyps. Even after successful eradication of Helicobacter pylori, he showed hypergastrinemia (480 pg/mL) owing to esomeprazole (proton-pump inhibitor) therapy for the past 4.

The conventional analysis method has problems with extraction efficiency, operability, and reproducibility. In this study, we attempted to solve these problems and improve the analytical method to obtain sufficient extraction efficiency and good operability and accuracy. The conventional method was able to get sufficient extraction in dried meat products, where the extraction efficiency of the conventional method was low, by increasing the concentration of sodium hydroxide solution at the time of homogenization.

The spread of antimicrobial-resistant bacteria (ARB) in natural environments including wild animals is a concern for public health. Birds cover large areas, and some fly across borders to migrate in large flocks. As a migratory bird, the Greater White-fronted Goose (Anser albifrons) travels to Miyajimanuma, North Japan, each spring and autumn.
