  • The present study was performed to investigate the putative anxiolytic-like effects of the aqueous extract of the roots of Scrophularia buergeriana (SB-W) using elevated plus-maze (EPM) and hole-board apparatus in mice. SB-W was orally administered at doses of 50, 100, 200 or 400 mg/kg to ICR mice, 1 h before the behavioral evaluation. Control group were administered with an equal volume of saline, and positive control group with buspirone (2 mg/kg, i.p.). The administration of SB-W significantly increased the percentage of time spent in open arms and entries into the open arms of the EPM compared with saline-treated control group (P < 0.05). Futhermore, those anxiolytic-like activities of SB-W were antagonized by flumazenil (a $GABA_A$ antagonist, 10 mg/kg), but not by WAY-100635 (a 5-$HT_{1A}$ antagonist, 0.3 mg/kg). Moreover, there were no changes in the locomotor activity and myorelaxant effects in any group compared with saline-treated control group. In the hole-board test, the administration of SB-W (200 and 400 mg/kg) significantly increased the number of head-dipping compared with saline-treated control group (P < 0.05). Therefore, these findings suggest that Scrophularia buergeriana promotes the anxiolytic-like activity mediated by GABAergic nervous system in mice.

  • The current article explores the aging effects on the overall morphology of the endplates of the 12th thoracic vertebra (T12), while screening for sex differences. It further evaluates the suitability of T12 for estimating age-at-death in bioarcheaological contexts. We captured the morphology of the vertebral endplates, including the formation of osteophytes, in a novel continuous quantitative manner using digital photography. 168 Greek adults from the Athens Collection were used for modeling the aging effects and another 107 individuals from two Danish archaeological assemblages for evaluation. Regression analysis is based on generalized additive models for correlating age-at-death and morphological variation. Our proposed measurement method is highly reliable (R>0.98) and the main differences observed between sexes are size related. Aging has considerable effect on the endplate morphology of the T12 with the total area of the endplate, the area of the epiphyseal rim, and the shape irregularities of the endplate's external boundary being mostly affected. Multivariate regression shows that aging effects account up to 46% of the observed variation, although with differential expression between sexes. Correct age prediction on archaeological remains reached 33% with a prominent tendency for overestimation. The morphology of the T12 endplates is influenced by age and it can provide some insight with respect to the age-at-death of unidentified individuals, especially when other skeletal age markers are unavailable. Our proposed method provides an age-estimation framework for bioarchaeological settings, especially for estimating broader age ranges, such as discriminating between young and old adults.

  • To investigate the effects of facial blood flow rates(FBFR) and facial skin temperature(FST) generated by Gagam-Jawoonaek(GJ) application(appl.) after Miso Facial Rejuvenation Acupuncture(MFRA). Ten people in their twenties to fifties with no skin diseases were recruited. We randomly divided subjects two groups(A, B) and set the GJ appl. site(group A - right side, group B - left side). MFRA was performed on both sides of their face. Immediately after acupuncture treatment(AT treat.), GJ was applied only half of the face. We measured their FBFR using Laser Doppler Perfusion Imaging(LDPI) and FST using Digital Infrared Thermal Imaging(DITI) at pre-AT treat., immediately after AT treat., twenty and sixty minutes after GJ appl.. We analyzed data using Mann-Whitney test and Wilcoxon test(p < 0.05). After MFRA treat., FBFR on both sides increased. Twenty minutes after JW appl., the changes of FBFR on GJ appl. side($122.9{\pm}43.1PU$) were bigger than GJ non-appl. side($80.9{\pm}38.4PU$), a statistically significant decrease. Sixty minutes after application, FBFR on both sides were recovered almost at the same level as that of pre-AT treat. After MFRA treat., FST on both sides increased. Twenty minutes after GJ appl., the changes of FST on GJ appl. side($1.1{\pm}0.6^{\circ}C$) were comparable to that of GJ non-appl. side($1.2{\pm}0.5^{\circ}C$). Sixty minutes after application, FST on both sides were recovered almost at the same level as that of pre-AT treat.. Gagam-Jawoonaek could decrease facial blood flow rates.

  • This study analyzed 28 domestic and foreign studies related Prompts for Restructuring Oral Muscular Phonetic Targets treatment techniques from 1984 to 2020 to prepare basic data for the development of PROMPT intervention programs and examination tools. According to the analysis, continuous research has been conducted since 1984 when the prompt study was first started, and the method of research was 16 intervention studies, with the highest number of speech disorders, and the target age being 3 to 5 years old, the most frequently conducted for infancy. The treatment was the most frequent in the 16th sessions, and the activities were based on the Motor Speech Hierarchy(MSH), except for the subjects of the non-verbal autism spectrum disorder. According to the analysis of the dependent variables, 'speech production' was the most common, followed by 'speech motor control', 'articulation', and 'speech intelligibility' were highest. Combined with all these studies, it suggests that PROMPT, which are directly useful for exercise spoken word production, are effectively being used outside the country and that it is necessary to develop a PROMPT program that can be applied domestically, in Korea.

  • The purpose of this study is to investigate the relationship between the characteristics of using new words, ability to use new words, and peer popularity among students with mild intellectual disabilities and general students of the age-matched group. A total of 8 students, 4 students with mild intellectual disabilities aged 14 to 16 years of age and 4 normal students in the age-matched group, were compared between groups using a nonparametric test. In the case of new words, 60 new words were selected through expert content validity among 301 new words, and then recognition and background information on the 60 new words were collected. As a result of the study, first, there was a significant difference in understanding of new words between the student group with mild intellectual disability and the general student group of the same age. Second, the correlation between the use of new words and the popularity of peers was compared for each group of students with mild intellectual disabilities and a group of general students of the same age as possible. Therefore, when providing vocabulary instruction for students with mild intellectual disabilities, it suggests that it is necessary to teach new vocabulary in order to increase their relationship with their peers and their popularity.

  • Background: Formation of new blood vessels is necessary for the development and spread of neoplasms more than 1 mm3 in volume, angiogenesis being responsible for formation of new from pre-existing blood vessels. Vascular endothelial growth factor (VEGF) is pivotal and the best studied angiogenic factor in all human cancers. Therefore we designed this study to investigate the role of VEGF-A and VEGF-C in prostate cancer in comparison with BPH controls in a north Indian population. Methods: In this case-control study a total of 100 subjects were included on the basis of confirmed histopathological reports, out of which 50 were prostate cancer patients and the other 50 were BPH patients with PSA levels >2 ng/ml and abnormal digital rectal examination (DRE) findings during September 2009 to August 2011 from the Department of Urology, KGMU, Lucknow, India. Plasma levels of VEGF were determined using quantitative immunoassay (ELISA-enzyme linked immunosorbent assay). Statistical analysis was carried out using SPSS 15.0 version. Results: The mean age of prostate cancer ($67.6{\pm}5.72$) patients was significantly higher (p=0.005) than BPH ($63.6{\pm}7.92$) patients. Expression of VEGF-A was not significantly higher in disease stage C1 than D1 or D2 and A or B (p=0.13) while the level of VEGF-A was significantly higher (p=0.04) in prostate cancer as compared to BPH subjects (PCa=13.0 pg/ml, BPH=6.8 pg/ml). Levels of VEGF-C were similar in both groups (PCa=832.6 pg/ml, BPH=823.7 pg/ml). In ROC curve, the area under curve (AUC) was 0.70 (95%CI: 0.60-0.80) and the cut-off value for which a higher proportion of patients was correctly classified (20%) was 26.0 pg/mL. Conclusion: Although VEGF-A is increased in cancer prostate patients a statistically significant correlation could not be established in this study. VEGF-C was not found to be a useful biomarker.

  • The purpose of this study is to examine the perception of the right to vote of persons with developmental disabilities in college students. College students attending in A University and B University in Gwangju Metropolitan City were selected using convenience sampling and 370 samples were finally analyzed. The results were as follows. First, the subjects who took a disability course had high perception of the right to vote of persons with developmental disabilities. Second, it was discovered that the more times people participated in the volunteer work related to disabilities, the more recognition they had on the voting rights of people with developmental disabilities. Third, the subjects who responded for the need for the political rights of persons with developmental disabilities had more positive perception of the right to vote of persons with developmental disabilities than those who did not responded. Based on the findings, it was suggested that methods should be investigated to establish positive attitude and perception of the right to vote of persons with developmental disabilities in persons without developmental disabilities including college students.

  • The image analysis is an important and predominant task for classifying the different parts of the image. The analysis of complex image analysis like histopathological define a crucial factor in oncology due to its ability to help pathologists for interpretation of images and therefore various feature extraction techniques have been evolved from time to time for such analysis. Although deep reinforcement learning is a new and emerging technique but very less effort has been made to compare the deep learning and deep reinforcement learning for image analysis. The paper highlights how both techniques differ in feature extraction from complex images and discusses the potential pros and cons. The use of Convolution Neural Network (CNN) in image segmentation, detection and diagnosis of tumour, feature extraction is important but there are several challenges that need to be overcome before Deep Learning can be applied to digital pathology. The one being is the availability of sufficient training examples for medical image datasets, feature extraction from whole area of the image, ground truth localized annotations, adversarial effects of input representations and extremely large size of the digital pathological slides (in gigabytes).Even though formulating Histopathological Image Analysis (HIA) as Multi Instance Learning (MIL) problem is a remarkable step where histopathological image is divided into high resolution patches to make predictions for the patch and then combining them for overall slide predictions but it suffers from loss of contextual and spatial information. In such cases the deep reinforcement learning techniques can be used to learn feature from the limited data without losing contextual and spatial information.

  • In order to examine the relationship between cholesterol level on serum and depression in Korean adults, this study used data of the fourth Korea National Health and Nutrition Examination Survey (KNHANES). 834 persons with depressive symptoms were selected as an index group and 3,317 persons without depressive symptoms as a control group, and odds ratios were calculated by multivariate logistic regression. As a result, odds ratio of depressive symptoms was higher in low LDL group (OR=6.435, 95% CI; 2,358-17.557) than in high LDL group adjusted after monthly income, marital status, period of education, occupation, smoking status, and physical activity. Etiopathogenic mechanism must be found by convergent study in the future.
