Background: Despite muscle latency times and patterns were used as broad examination tools to diagnose disease and recovery, previous studies have not compared the dominant arm to the non-dominant arm in muscle latency time and muscle recruitment patterns during reaching and reach-to-grasp movements. Objects: The present study aimed to investigate dominant and non-dominant hand differences in muscle latency time and recruitment pattern during reaching and reach-to-grasp movements. In addition, by manipulating the speed of movement, we examined the effect of movement speed on neuromuscular control of both right and left hands. Methods: A total of 28 right-handed (measured by Edinburgh Handedness Inventory) healthy subjects were recruited. We recorded surface electromyography muscle latency time and muscle recruitment patterns of four upper extremity muscles (i.e., anterior deltoid, triceps brachii, flexor digitorum superficialis, and extensor digitorum) from each left and right arm. Mixed-effect linear regression was used to detect differences between hands, reaching and reach-to-grasp, and the fast and preferred speed conditions. Results: There were no significant differences in muscle latency time between dominant and non-dominant hands or reaching and reach-to-grasp tasks (p>.05). However, there was a significantly longer muscle latency time in the preferred speed condition than the fast speed condition on both reaching and reach-to-grasp tasks (p<.05). Conclusion: These findings showed similar muscle latency time and muscle activation patterns with respect to movement speeds and tasks. Our findings hope to provide normative muscle physiology data for both right and left hands, thus aiding the understanding of the abnormal movements from patients and to develop appropriate rehabilitation strategies specific to dominant and non-dominant hands.
Background: Breast cancer is the most common cancer of women and the principal cause of death in middle aged women. The objective of this study was to describe the trend of breast cancer and its management in Aden and adjacent south-eastern governorates of Yemen during the last 20 years. Patients and Methods: This is a retrospective analysis of previous studies on patients with breast cancer in Aden and adjacent south-eastern governorates, Yemen (January 1989 through December 2007). The studied variables were: sex, age, time and type of presentation, disease stage, pathological types and the performed surgical treatment. The sources of information were the treatment registry of Aden health office, archives of Al-Gamhouria teaching hospital; major referral and other public and private hospitals in Aden and Aden Cancer Registry. Results: The total number of patients was 476, 99% being females. The age range was 19-88 years. The most affected age was 30-50 years (60.5%), 95% presenting after one month of having breast symptoms. Forty-five percent presented with signs of advanced local disease, while 59.2% had palpable axillary lymph nodes on presentation. Early breast cancer (stages I-II) occurred in 47%, and late breast cancer (stages III-IV) in 51.5%. Invasive ductal carcinoma was the commonest pathology (89.3%). The main surgical treatment was mastectomy (modified radical mastectomy (50%). Conclusion: Breast cancer is predominantly a disease of young with late presentation and advanced disease. Improving health awareness and earlier diagnosis of the disease by health education, encouraging breast self-examination, and providing the mammography equipment and mammary clinics in hospitals are recommended. Establishment of oncology and radiotherapy centers in Aden is a necessity.

We have investigated efficiency of a recombinant subunit Pasteurella multocida toxin (PMT) that was mixed with a vaccine consisted of inactivated whole cells of Bordetella bronchiseptica, P. multocida (types A and D). For verification of the efficacy of the vaccine, all experimental pigs (suckling piglets, sow and gilts) in the three farms were vaccinated. Antibody titers against B. bronchiseptica and P. multocida type A of the vaccinated pigs by microplate agglutination were significantly higher than those of the control pigs (p < 0.05). Similar patterns were observed in the analysis of anti- PMT neutralizing antibody by serum neutralizing method using Vero cell (p < 0.05). Anti- P. multocida type D antibody titer of the vaccinated sows and gilts by ELISA showed significant differences with those of the non-vaccinated pigs (p < 0.05). Although antibody titers increased, it was unable to find out the difference in the clinical signs between the vaccinated and non-vaccinated pigs. However, the increase in body weight of the vaccinated piglets was observed in comparison with the non-vaccinated piglets on a farm. At slaughtering of the pigs, pathological lesions in the turbinate bones of the vaccinated pigs were significantly lower than those of the non-vaccinated pigs (p < 0.001). These results suggested that efficacy of the vaccine in pigs demonstrated to protect against atrophic rhinitis in Korea.

The Wenbing tiaobian(온병조변) is the first systematic disease monograph on warm factor disease(온병), written by Wu Jutong(오국통). It was most influenced by the Linzheng zhinan yian(임증지남의안), which was a book of gathering medical case records of Ye tianshi(엽천사). Therefore, there are plenty of quotations from this book in the Wenbing tiaobian. This study investigates the quotations from Linzheng zhinan yian, especially focusing on the way of transformation and correction of the original medical case records on the warm factor disease. The results are as follows: About 104 of 265 provisions in the Wenbing tiaobian were directly quoted from the Linzheng zhinan yian. The provisions quoted from Ye's case records were rearranged according to the categories of the triple burners pattern differentiation(삼초변증) and the causes of warm factor disease. And eve case record was transformed into more general descriptive form in order to put it into the book. For example, the specific figures, and some patients' peculiar symptoms, causes, sex and disease names were omitted. On the other hand, the tongue moss, pulse shape and some symptoms, which were necessary for differentiating patterns, were added. In the case of the formula, some formulas originated from Ye's case records were named newly. And the dose of each herb consisting a formula was determined, and therapeutic principle, taking method and detailed explanation was added to every formula.

The purpose of this study is to investigate the relative influence of diet and physical activity on obesity. The subjects were 155 adults aged 35-52 years from 24 neighborhood committees in 4 urban districts of Beijing (male : 78, female : 77). They were divided into normal weight, overweight and obese groups according to their BMI. The general information of the subjects was collected by interview-administered questionnaire. Dietary intake was obtained by three-day(two weekdays and one weekend day) food weighted method, physical activity was assessed by a validated combination of data obtained from activity monitors, bicycling information and activity records. There were no significant differences of age, gender, height, educational, family economic level, smoking and drinking between different groups. The proportion of flour intake was higher in obese group compared to normal weight and overweight groups, and that of vegetables is lower in obese group. The physical activity (PAL) was not significantly different between two groups of the normal, overweight and obese groups. After the adjustment for confounding factors using logistic regression model, we found that the proportion of flour intake was positively associated with obesity, while the proportion of vegetable intake was inversely associated with obesity. It is concluded that dietary patterns were associated with obesity and diets composed of more vegetables and less staple combined with physical activities could contribute to obesity prevention.
This study was designed to investigate the correlation between nutrition status and cardiovascular disease in type 2 diabetes patients with metabolic syndrome. The subjects were 66 patients and divided into Non MS (a group without metabolic syndrome, n = 37) and MS (a group with metabolic syndrome, n = 29). The percentage of patients accompanying metabolic syndrome was 43.9% and family history such as DM, skipping meal and eating speed were higher in MS (P < 0.05) The average values of BMI, body fat (%), waist circumference were significantly higher in patients of MS than that of Non MS. For hamatological values, MS showed higher FRS, HOMA-IR, LDL-Cholesterol, CRP. Percentage of FRS was 21.63% in MS that is relatively higher in comparison with 16.81% in Non MS. Moreover, the incidence of cardiovascular disease appeared 13.8% in MS that is higher than 2.7% in Non MS. The intake of sodium and vitamin E were higher, but the intake of fat, vitamin A and zinc were lower in MS than in Non MS. Close correlations were elucidated among FRS, occurrence of cardiovascular disease, weight, waist circumference, Total-Cholesterol, LDLCholesterol, sodium in both groups. In conclusion, cardiovascular disease risk factors would be higher in type 2 diabetes patients with metabolic syndrome and there were distinctive patterns that were associated with hamatological values, nutrition intake risk factors. This result should be considered when designing nutrition study and intervetion programs.

Alzheimer's disease is a brain disorder that worsens over time and affects millions of people around the world. It leads to a gradual deterioration in memory, thinking ability, and behavioral and social skills until the person loses his ability to adapt to society. Technological progress in medical imaging and the use of artificial intelligence, has provided the possibility of detecting Alzheimer's disease through medical images such as magnetic resonance imaging (MRI). However, Deep learning algorithms, especially convolutional neural networks (CNNs), have shown great success in analyzing medical images for disease diagnosis and classification. Where CNNs can recognize patterns and objects from images, which makes them ideally suited for this study. In this paper, we proposed to compare the performances of Alzheimer's disease detection by using two deep learning methods: You Only Look Once (YOLO), a CNN-enabled object recognition algorithm, and Visual Geometry Group (VGG16) which is a type of deep convolutional neural network primarily used for image classification. We will compare our results using these modern models Instead of using CNN only like the previous research. In addition, the results showed different levels of accuracy for the various versions of YOLO and the VGG16 model. YOLO v5 reached 56.4% accuracy at 50 epochs and 61.5% accuracy at 100 epochs. YOLO v8, which is for classification, reached 84% accuracy overall at 100 epochs. YOLO v9, which is for object detection overall accuracy of 84.6%. The VGG16 model reached 99% accuracy for training after 25 epochs but only 78% accuracy for testing. Hence, the best model overall is YOLO v9, with the highest overall accuracy of 86.1%.
Previous studies concerning the usefulness of pleural fluid glucose levels in differentiating causes of pleural effusions have been conflicting. Gelenger and Wiggers (1949), Calnan et al(1951) and Barber et al(1957) concluded that the lower the level of pleural fluid glucose, the more likely was tuberculosis, and that tuberculosis was unlikely if the pleural fluid glucose level was more than 80 mg/100 ml. Light and Ball(1973), however, reported that in the great majority of tuberculous pleural fluids the glucose concentration was high rather than low, concluded that the pleural fluid glucose levels were not useful in the differential diagnosis of pleural effusion. In this study, pleural fluid glucose was determined in 46 pleural effusions from various causes to evaluate the usefulness in the differential diagnosis of pleural effusion. In addition, the protein concentration and the electrophoretic patterns of protein and amylases in pleural fluid was compared with that of serum. And the results were as follows. 1. The mean glucose concentration of pleural fluid was 80.8 mg/100 ml in 22 tuberculous origin, 92.5 mg/100 ml in 12 cancer patient and 70.4 mg/100 ml in 10 undiagnosed cases. In 2 cases of paragonimiasis the pleural fliud glucose levels were low (mean, 32.0 mg/100 ml). The percentage of pleural fluid protein to serum is about 75% in all disease groups and the protein level of tuberculous pleural fluid was significantly correlated with that of serum. 2. The disc eletrophoretic patterns of pleural fluid were almost similar with that of serum in all disease groups but the prealbumin fraction was not observed in pleural fluid. 3. With the isoelectric focusing, 4 to 7 isoamylase was observed in serum and the isoelectric point was ranged from pH 5.8 to 7.8 and isoelectic point of main fracticn is pH 7.2. The isoelectic focusing patterns of amylase of pleural fluid were identical to that of serum in all disease group. With the above results it is concluded that the pleural fluid is exudate of serum and that the glucose levels of pleural fluid are not useful in the differential diagnosis of pieural effusions.
Objectives : The 7-zone-diagnostic system is a diagnostic device to predetermine bodily locations by measuring the energy of body. This study was to investigate the relation between the different patterns of Zone 2 of Factor AA in CP-6000A (VEGA, Germany), 7-zone-diagnostic system and the factors of Bell's Palsy. Methods : This study was carried out with the data from factors of Bell's Palsy(age, sex, period after onset, postauricular pain, season which the disease happen, contributing factor). We made three groups according to the different patterns of Zone 2 of Factor AA in CP-6000A. The Factor AA pattern of Group A is that the red bar graph of zone 2 were lower than the normal range. The Factor AA pattern of Group B was that the red bar graph of zone 2 was the normal range. The Factor AA pattern of Group C was that the red bar graph of zone 2 was higher than the normal range. After collecting the data about factors of Bel's Palsy to correspond with conditions of each group were selected, the data was analyzed statistically. Results : The values of number of patient and period after onset of group A was higher than group B and C. The values of ratio of postauricular pain of group B and C was higher than group A. The season of disease happened of group A is spring and winter, group B is winter and group C is summer and autumn. The contributing factor of disease happened of group A is none, and group B and C is stress and clod. Conclusions : In Bell's Palsy, it is thought that the red bar graph of zone 2 is lower, the group have lower energy(虛) and the energy has a character of cold(寒), and zone 2 is higher, the group has the higher energy(實) and the energy has a character of fire(熱).
The molecular genetic characterization of Aujeszky's disease virus (ADV) Yangsan strain (ADVYS), a Korean isolate, was investigated by analyzing the electrophoresis patterns and the physical maps of the viral DNA digested with various endonucleases. To establish DNA library for ADV-YS, twelve major BamHI restricted segments were cloned. Each location of the segments in the ADV genome was determined by sequence comparison with the sequences reported in Genbank and those sequences of the both termini of the segments. Physical maps were constructed based on the electrophoresis patterns of the digested viral DNA by restriction endonuclease and the results of Southern blot analyses with various DIG labeled probes originated from those of enzyme restricted segments of virulent (Shope) and avirulent (Bartha) strain. Comparing ADV-YS with a standard strain of Kaplan in the maps of restriction enzymes, following major respects were identified: (i) disappearance of BamHI restriction site between the first and second BamHI segments, (ii) creation of the BamHI restriction site in the fifth segment, and (iii) generation of the BglII site in the unique short (US) region. The genome of ADV-YS also contains a type 2 herpesvirus DNA molecule (in which the US region only inverts itself relative to the unique longregion) like all other ADV strains except Norden strain(type3), analyzed up to date. The size of the ADV genome estimated from the sizes of the restriction enzyme fragments, was approximately 145.3 kb (BamHI) or 145.4 kb (BglII). BamHI enzyme cleavage patterns were compared among the five Korean ADV isolates: Yangsan, Yongin, Dangjin, Jincheon and Iksan strains. Difference either in the number or in the size of the DNA fragments, suspected regions of termini of IR and TR, could be detected among all five strains.
