Objectives: Parkinson's disease is characterized by progressive, irreversible damage to dopamine neurons in the substantia nigra pars compacta, as well as motor and non-motor symptoms. This disease currently has no dependable disease-modifying treatment. In this paper, we describe the treatment of a 67-year-old female with Parkinson's disease using acupuncture and exercise therapy. Case Presentation: Clinical symptoms and the United Kingdom Parkinson's Disease Society Brain Bank Diagnostic Criteria were used to diagnose the patient with Parkinson's disease. Over a 12-week period, the patient visited a Korean medicine hospital 18 times and was treated with acupuncture and exercise therapy in addition to anti-Parkinson's drugs. Before and after treatment, clinical examinations were performed using tools such as the Unified Parkinson's Disease Rating Scale, Fall Efficacy Scale, Parkinson's Disease Questionnaire, Berg Balance Scale, and Non-Motor Symptoms Scale. Furthermore, functional near-infrared spectroscopy was used to assess cortical hemodynamics. All clinical examination results improved after 12 weeks of intervention. In particular, improvements on the Total Unified Parkinson's Disease Rating Scale and Part III of this scale demonstrated large, clinically important differences. Conclusion: This case suggests that combining acupuncture and exercise therapy could produce an effective treatment for Parkinson's disease patients.

With the development of artificial intelligence, efforts to incorporate neuroscience mining with AI have increased. Neuroscience mining, also known as NSM, expands on this concept by combining computational neuroscience and business analytics. Using fNIRS (functional near-infrared spectroscopy)-based experiment dataset, we have investigated the potential of NSM in the context of the BPSC (business problem-solving creativity) prediction. Although BPSC is regarded as an essential business differentiator and a difficult cognitive resource to imitate, measuring it is a challenging task. In the context of NSM, appropriate methods for assessing and predicting BPSC are still in their infancy. In this sense, we propose a novel NSM method that systematically combines CNN, BiLSTM, and attention network for the sake of enhancing the BPSC prediction performance significantly. We utilized a dataset containing over 150 thousand fNIRS-measured data points to evaluate the validity of our proposed NSM method. Empirical evidence demonstrates that the proposed NSM method reveals the most robust performance when compared to benchmarking methods.

Objectives Maltreatment experiences can alter brain function related to emotion regulation, such as cognitive reappraisal. While dysregulation of emotion is an important risk factor to mental health problems in maltreated people, studies reported alterations in brain networks related to cognitive reappraisal are still lacking. Methods Twenty-seven healthy subjects were recruited in this study. The maltreatment experiences and positive reappraisal abilities were measured using the Childhood Trauma Questionnaire-Short Form and the Cognitive Emotion Regulation Questionnaire, respectively. Twelve subjects reported one or more moderate maltreatment experiences. Subjects were re-exposed to pictures after the cognitive reappraisal task using the International Affective Picture System during fMRI scan. Results The maltreatment group reported more negative feelings on negative pictures which tried cognitive reappraisal than the no-maltreatment group (p < 0.05). Activities in the right superior marginal gyrus and right middle temporal gyrus were higher in the maltreatment group (uncorrected p < 0.001, cluster size > 20). Conclusions We found that paradoxical activities in semantic networks were shown in the victims of maltreatment. Further study might be needed to clarify these aberrant functions in semantic networks related to maltreatment experiences.

Functional cosmetics containing various ingredients that improve skin health are currently being developed. In addition, technologies that help increase the absorption rate of such cosmetics have recently gained significant attention. Sonophoresis is a method to increase the transdermal absorption of cosmetics using ultrasound. A skin-mimicking phantom was fabricated using polydimethylsiloxane, Strat-M^TM membrane, and thermochromic pigments. Gel-type cosmetics used in skin mask packs and epidermal-growth-factor-based nano-cosmetics were tested for their absorption rates at ultrasound frequencies of 1, 3, and 10 MHz in the single frequency mode, and 1/3 and 3/10 MHz in the dual frequency mode. The gel-type cosmetics and epidermal-grow-factor-based nano-cosmetics showed the highest absorption rate at 3/10MHz dual frequency. The size of the cosmetic particles decreased by 5-9 %. Furthermore, the temperature rise caused by ultrasound could be visually recognized by the thermochromic pigment in the phantom turning white. We presented a skin-mimicking phantom. The device can be customized according to the size of the ultrasound probe and has the advantage of quantitatively evaluating the transdermal permeability of cosmetics at a low cost. The development of the skin-mimicking phantom will be useful for determining the suitable conditions required to increase the absorption rate of cosmetics using ultrasound.

We investigated the nutritional characteristics and antioxidant effects of sea mustard Undaria pinnatifida fractions from Gultongmeori in Taejongdae, Youngdo, Busan. Based on dry weight, the moisture, crude protein, crude lipid, crude ash, and crude fiber contents were 34.98%, 11.55%, 0.43%, 17.82%, and 3.45%, respectively. To evaluate the antioxidant effect, we used radical scavenging (DPPH and ABTS), reactive oxygen species (ROS) production measurement, and DNA oxidation assays. Total flavonoid and phenol contents were higher in the n-hexane fraction than in other fractions. The n-hexane fraction was more effective at scavenging free radicals than other fractions as assessed using DPPH and ABTS assays (P<0.05). The ROS production assay showed that all sea mustard fractions decreased H₂O₂ induced cellular ROS production compared to that seen in the control (P<0.05); however, the n-hexane fraction reduced cellular ROS production to a greater extent than the other fractions. Furthermore, the n-hexane fraction from Gultongmeori significantly inhibited genomic DNA oxidation. These results indicate that the antioxidant effect of sea mustard is associated with its high flavonoid and phenol content. This study proposes that processed food products supplemented with sea mustard can be developed as functional foods to promote health in the local population.

Camel milk has a significant and pivotal role in the diet of people residing in semi-arid and arid regions. Ever since ancient times, marketing of camel milk has remained insignificant due to nonexistence of processing amenities in the camel nurturing areas, hence the utilization of unprocessed camel milk has continuously remained limited at family level by the nomads. Due to the superior medicinal values and health promoting effects, incredible growth in the demand of camel milk and dairy products have been noticed all over the world during last two decades. Such emergence has led dairy industry to provide diversified camel dairy products to the consumers with superior nutritional and functional qualities. In contrast to bovine, very few food products derived from camel milk are available in the present market. With the advancements in food processing interventions, a wide range of dairy and non-dairy products could be obtained from camel milk, including milk powder, cheese, yogurt, ice cream, and even chocolate. In some regions, camel milk is used for traditional dishes such as fermented milk, camel milk tea, or as a base for soups and stews. Current review highlights the processing opportunities regarding the transformation of camel milk into various dairy products via decreasing the inherent functionality that could be achieved by optimization of processing conditions and alteration of chemical composition by using fortification method. Additionally, future research directions could be devised to improve the product quality.

The canine tooth is important both functionally and aesthetically, being positioned between the anterior and posterior teeth. The upper canine has the longest eruption path, forming in the deepest part of the maxillary bone and often experiencing eruption disorders, leading to significant aesthetic and functional issues. Early detection and management of canine impaction are crucial in pediatric dentistry, which focuses on tooth growth and eruption. The prevalence of maxillary canine impaction ranges from 1.1% to 3.0%. In Western populations, palatal impaction is twice as common as labial impaction, while some Korean studies report more labial impaction. Maxillary canine impaction occurs more frequently in women and is associated with various factors such as structural obstacles, pathological conditions in surrounding tissues, developmental abnormalities, and genetic factors. Labial displaced canines are linked to narrow maxillary intercanine width, total dental crowding, and skeletal Class III malocclusion. Maxillary palatal displaced canine impaction is more prevalent in patients with familial agenesis of lateral incisors or conical supernumerary lateral incisors. Understanding these factors aids in early diagnosis and appropriate intervention for canine tooth impaction, ensuring optimal oral health and aesthetics.

PURPOSE: This study aimed to investigate the relationship between being underweight and respiratory function indicators such as pulmonary function, respiratory muscle strength, and diaphragm thickness in normal adults without lung disease. METHODS: The participants in this experiment were thirty young adults. To compare the respiratory function between the underweight and normal weight individuals, 15 participants were selected from each of the underweight and normal weight groups based on body mass index. Respiratory function tests were conducted through pulmonary function tests and respiratory muscle strength tests. Diaphragm thickness was measure with ultrasonography, and physical characteristics were obtained from grip strength and waist circumference. An independent t-test was used to compare the averages of the parameters measured in the two groups. RESULTS: In the respiratory function tests between the two groups, statistically significant differences (p < .05) emerged in the ratio of the predicted forced vital capacity (%FVC), the ratio of the predicted forced expiratory volume in one second (%FEV1), maximal expiratory pressure (MEP), and diaphragm thickness at the functional residual capacity (FRC). There was no statistically significant difference in the forced vital capacity, forced expiratory volume in one second, maximal inspiratory pressure, diaphragm thickness at the total lung capacity, and thickening ratio (p > .05). CONCLUSION: Decreases in some variables of respiratory function, such as the %FVC, %FEV1, MEP, and diaphragm thickness at the FRC were observed in underweight subjects. However, it is difficult to determine whether it affected the overall respiratory function. Future studies are needed to clearly identify the relationship between being underweight and respiratory function.

Purpose: This study investigated nursing care delivery systems in 44 university affiliated hospitals and satisfactions with the systems perceived by 226 unit managers (head nurses) of general medical surgical wards. Methods: Data were collected with questionnaires consisting of checklists asking the unit managers their nursing care delivery systems and their satisfactions with the systems. Results: Four models of nursing care delivery systems (primary, modified primary, team, and functional models) were drawn from the participants' responses. Among the four key models 35% of the units adopted team model whereas 24.3% adopted primary model and 22.6% adopted modified primary model. In spite of 35% of team model being under use, 60.6% (n=137) of the unit managers answered the nursing delivery system of their units as team model and only 6.2% (n=14) answered their units having primary or modified primary models, instead of 46.9% combining both. In regard to the satisfaction, critical thinking ability of staff nurses (members in their units) was the most dissatisfactory area regardless of models of service delivery. Conclusion: Introducing team model supplemented with core concepts of primary model (primary team delivery model) into nursing practice will reform the workplace and therefore deliver safe health care services to patients.
