A plant fermentation was carried out by Yeast and Lactobaccilli against fermented black turmeric, Kaempferia parviflora (FBT). These materials were proved by as safe in animal safety experiment. We tried to investigate changes of immune-competent cells that commonly utilized FBT, including after administration of immno-suppressed animals, the effects by FBT on the regulated effect on the cells were evaluated. Our results showed that FBT augmented the level of lymphocytes in number, while FBT regulated the level of granulocytes in both number and function. In our clinical study with 20 healthy volunteers, granulocyte and lymphocyte ratio suggesting their constitution as neutral in peripheral blood were increased significantly 30 days after the administration of FBT in rodents, and compromised host was prepared with cancer chemotherapeutic agent (Mytomycin-C). Our observations showed against intracellular parasite, and that FBT augmented intercellular pathogen through humoral immunity. We discussed the significance and mechanism of FBT on the level of leukocyte subsets in number and function that were considered to be potential indicators for the activation of the compromised host. We also proposed an idea that FBT exhibited tonic effects via activating complement components. The evidences were shown by immune-electrophoretic method. Moreover, we tried to access further to the anti-oxidative activities of this FBT. This modification brought to the significant lift up for antibody producing cells and anti-oxidative activity for phagocytic cells.

A plant material consisted by Family Poaceae was fermented by Yeast and Lactobaccilli (U-164). This material was proved by as safe in animal safety experiment for oral administration. In order to prove the effect of U-164 against physiological function, the animal and human trials were set up to look into mainly leukocyte functions. In animal experiment, anti-oxidative effect and antibody response in immune-compromised host and diabetes meritus were made up. For human use, peripheral lymphocyte in number and subset ratio were followed up to one month after administration. In order to understand its effect, human complement component analysis was made by immune-electrophoresis. Our results showed that U-164 augmented the level of lymphocytes, while U-164 down regulated the level of granulocytes. In our clinical study with 19 healthy volunteers, granulocyte and lymphocyte ratio was obtained as neutral in peripheral blood being increased significantly 30 days after the ingestion of U-164. In experimental animal study, the compromised host as well as normal animal was administered with cancer chemotherapeutic agent (Mytomycin-C). Our observations showed against antibody producing cell, this material recovered the antibody production in the host compromising the immure responsiveness. We also proposed an idea that U-164 exhibited tonic effects via activating complement components. Moreover, we tried to access further to the anti-oxidative activities of this U-164. This modification brought to the significant lifted up for anti-oxidative activity for phagocytic cell.

Unraveling the mechanism underlying topological phases, notably the Chern insulators(Ch Is) in strong correlated systems at the microscopy scale, has captivated significant research interest. Nonetheless, Ch Is harboring topological information have not always manifested themselves, owing to the constraints imposed by displacement fields in certain experimental configurations. In this study, we employ density-tuned scanning tunneling microscopy(DT-STM) to investigate the Ch Is in twisted monolayer–bilayer graphene(t MBG). At zero magnetic field, we observe correlated metallic *** under a magnetic field, a metal–insulator transition happens and an integer Ch I is formed emanating from the filling index s = 3 with a Chern number C = 1. Our results underscore the pivotal role of magnetic fields as a powerful probe for elucidating topological phases in twisted Van der Waals heterostructures.

Person identification is one of the most vital tasks for network security. People are more concerned about theirsecurity due to traditional passwords becoming weaker or leaking in various attacks. In recent decades, fingerprintsand faces have been widely used for person identification, which has the risk of information leakage as a resultof reproducing fingers or faces by taking a snapshot. Recently, people have focused on creating an identifiablepattern, which will not be reproducible falsely by capturing psychological and behavioral information of a personusing vision and sensor-based techniques. In existing studies, most of the researchers used very complex patternsin this direction, which need special training and attention to remember the patterns and failed to capturethe psychological and behavioral information of a person properly. To overcome these problems, this researchdevised a novel dynamic hand gesture-based person identification system using a Leap Motion sensor. Thisstudy developed two hand gesture-based pattern datasets for performing the experiments, which contained morethan 500 samples, collected from 25 subjects. Various static and dynamic features were extracted from the handgeometry. Randomforest was used to measure feature importance using the Gini Index. Finally, the support vectormachinewas implemented for person identification and evaluate its performance using identification accuracy. Theexperimental results showed that the proposed system produced an identification accuracy of 99.8% for arbitraryhand gesture-based patterns and 99.6% for the same dynamic hand gesture-based patterns. This result indicatedthat the proposed system can be used for person identification in the field of security.

Background: From the two facts reported by previous research: 1) frequent co-occurrence of more than one addictive behavior, 2) childhood adversities identified as origins of different types of addictive behaviors, it is assumed that all types of addictive behaviors, regardless of substance, behavioral, or relationship, share common factors which have not yet been proven by epidemiological research. The Shorter PROMIS Questionnaire (SPQ) was previously developed to assess 16 types of addictive behaviors. Its factor structure, however, has not been fully investigated. Confirming the factor structure will enable us to hypothesize the common factor(s) shared by all, or if not all, most types of addictive behaviors. Aims: This study aimed at 1) examining the factor structure of the SPQ, 2) confirming the reliability of the questionnaire, and 3) examining the impacts of gender and age on each addictive behavior. Methods: Data obtained from 232 Japanese adults who completed all items of the SPQ were used for the analyses. After confirming the one-factor structure model for each of the 16 subscales, the validity of the one-factor structure of the SPQ was evaluated using Confirmatory Factor Analysis (CFA), by adapting 16 subscale scores as observed variables. If its validity was not confirmed, another model which showed better compatibility to the data was explored. The reliability of the SPQ as well as that of all 16 subscales was evaluated. Also, the impacts of gender and age on each subscale score were examined. Results: The one-factor structure for each of the 16 subscales was confirmed. The compatibility of the SPQ one-factor model was not acceptable. The best fit model was a bi-factor model in which one main factor was shared by all 16 subscales, and three factors were shared by some specific addictive behaviors. Male respondents were more likely than female respondents to show high scores in Alcohol, Tobacco, Gambling, Sex, and Recreational Drugs, and low scores only

Purpose: Umami reportedly promotes salivation. We aimed to investigate the effects of taste stimuli on slow and fast salivary secretion in humans using umami, sweet, and sour stimuli. Methods: Eight healthy women participated between 14:00 and 15:00, taking the circadian rhythm of salivary secretion into account. The types and concentrations of the taste solutions were glutamic acid (1.7 × 10−3 M), inosinic acid (9.8 × 10−3 M), and guanylic acid (9.8 × 10−3 M) for umami stimulation, citric acid (6.5 × 10−3 M) for acidity stimulation, and sucrose (1.6 × 10−2 M) for sweetness stimulation. First, the unstimulated salivary flow rate was measured. Then, 3 ml of a flavor solution was dropped under the tongue using a syringe. The saliva was expelled into an aluminum cup every minute and weighed. The first minute’s value minus 3 ml flavor solution was the stimulated salivary secretion rate produced by each flavor. The time-to-return to the initial unstimulated salivary flow rate was the duration of the stimulated saliva secretion rate. Results: The mean unstimulated salivary flow rate across participants was 0.64 ± 0.25 ml/min (range: 0.23 - 1.03 ml/min). The highest amount of saliva was induced by citric acid. There were significant differences between citric acid and the other flavor solutions (p < 0.05 for glutamic acid, inosinic acid, and sucrose;p < 0.01 for guanylic acid). There were no significant differences in duration of salivation between the flavor solutions. When the participants were divided into slow (0.45 ± 0.16 ml/min) and fast groups (0.83 ± 0.15 ml/min) based on their median resting salivary secretion rate, there were no significant differences between the two groups in the amount of saliva secreted at 1 minute after stimulation and the duration of the salivary secretion rate. Conclusion: Umami stimulation was effective in slowing salivary secretion and sustaining salivary secretion after stimulation.
