  • This paper describes the construction of an anisotropic three dimensional ventricular model based on the bidomain model. The cardiac artivation process in the normal cardiac cell and the myocardiac ischemic cell are simulated by the Huygen's principle. The depolarization process in the myocardial ischemia displays the delayed activation compared to the normal state. The repolarization process is simulated by the myocardial potential at the arbitrary ellapsed time after activation process.

  • Although the incidence of breast cancer in Asia remains lower than in North America, Western Europe, and Oceania, rates have been increasing rapidly during the past few decades, and Asian countries now account for 40% of breast cancer cases diagnosed worldwide. Breast cancer mortality has also increased among Asian women, in contrast to decreased mortality in Northern America, Western Europe, and Oceania. These increased rates are associated with higher prevalence of breast cancer risk factors (e.g., reduced parity, delayed childbirth, increased obesity) that have accompanied economic development throughout the region. However, Asian regions (western, south-central, south-eastern, and eastern) and countries differ in the types and magnitude of changes in breast cancer risk factors, and cannot be viewed as a single homogeneous group. The objective of this paper was to contrast the heterogeneous epidemiology of breast cancer by Asian regions and countries, and to suggest potential avenues for future research.

  • Maintenance therapy has emerged as a novel therapeutic paradigm for advanced non-small-cell lung cancer (NSCLC). Maintenance therapy that aims to sustain a clinically favorable state after first-line chemotherapy has two strategies. Switch maintenance therapy entails switching to a new and non-cross-resistant agent in an alternating or sequential manner, on completion of first-line chemotherapy. Continuous maintenance therapy keeps ongoing administration of a component of the current regimen after four to six cycles of chemotherapy, if there is a stable disease, or better response. Both maintenance therapies can be continued, until disease progression. The potential evidence regarding maintenance therapy includes providing the opportunity to receive additional treatment, through sustaining tumor shrinkage, and delayed emergence of tumor-related symptom. Thus far, debates over the parameters used to predict the effectiveness of maintenance therapy, financial burden, and uncertainty of improving the quality of life exist. Despite many debates, maintenance therapy, which is currently recommended, has been disclosed to be beneficial.

  • The sugar alcohols are useful alternatives to sucrose in confections because they provide desirable taste but lessen the potential risks for dental caries. The effects of sugar alcohol and their interaction on starch pasting properties were determined by the viscoamylograph with the concentration of 30%, 20%, 10% sugar alcohol in 1% CMC. The disaccharides, lactitol, maltitol, and isomalt, delayed pasting more than did monosaccharides, sorbitol and xylitol. With regard to the solubility in water, sorbitol and xylitol are more soluble than sucrose, maltitol and lactitol are almost equal and isomalt is less soluble than sucrose. Sorbitol and xylitol were highest on gelatinization. But their retrogradation occurred faster than other sugar alcohols. Lactitol and maltitol decreased gel strength more than did sucrose and other sugar alcohols.

  • As is the case in Korea, the expansion of renewable energy dissemination is an essential matter in Ukraine when considering its energy consumption and dependence on energy import. While Korea has set about promoting the new and renewable energy industry on the back of the national policy on green growth, Ukraine expects a virtuous circle of renewable energy industry with green tariffs and the attraction of foreign capital in association with carbon emission trade. Utilizing its well-developed heavy industrial sector including the shipbuilding and automobile industries, Korea expects wind turbine manufacturing to become one of its next-generation growth engines. Ukraine is also trying to enter the wind turbine system or parts manufacturing industry based on its automobile industry and advanced aerospace technology. Although the Crimean region in Ukraine seems to have excellent wind resources, and thus shows great potential as a location for wind farm development, political instability has been a major obstacle to the attraction of foreign capital, leading to delayed investment.

  • An experiment was carried out using pots to investigate the effects of Chinese milk vetch on the seedling establishment and growth in rice. Four irrigations with five-day intervals and three different levels of vetch straw were investigated. Significantly higher panicle numbers were obtained in vetch-treated pots. Vetch levels were non-treatment as checks, vetch with top removed, root plus shoot 7.5 ton/ha, and root plus shoot 3.0 ton/ha. The time for complete degradation of vetch straws was reduced from 10 days to 5 days as submerged time was delayed, and was affected by the amount of mulched vetch straws. As the mulched vetch amount increased, the time for a complete degradation was extended from 4 days to 12 days. Grain yield and its components were significantly affected by irrigation time and mulched vetch amount. Effectively controlled, lowered reduction damage from the degrading vetch straw, irrigation date and vetch amount were the most important factors for the improving of seedling establishment in direct-sown rice.

  • Caragana sinica (Leguminosae) is a plant, which has been used as a traditional medicine for the treatment of lots of diseases including neuralgia, goat, hypertension and eczema. However, scientific studies of C. sinica in pharmacological aspects are not carried out. In this study, the anti-nociceptice effect of methanolic extract of C. sinica (MCS) was evaluated using various pain models. Our data represented that MCS significantly delayed the latency time under central pain condition which are arose from thermal stimuli, indicating MCS possess analgesic potential against central nociception. In addition, MCS showed strong and dose-dependent anti-nociceptive activities on acetic acid-induced peripheral pain, compared to positive control such as indomethacin. Further combination studies using naloxone, a non-selective opioid receptor antagonist, have revealed that analgesic activity of MCS was not changed in the presence of naloxone, indicating MCS exerts anti-nociceptive activity independent of opioid receptor. These results suggest that MCS may be an effective medicine in managing pain.

  • Glomus tumours are vascular hamartomas that are commonly found in the hand, particularly the subungual region. They appear as solitary or multiple tumours, and often present as a bluish discoloration of the nail plate. Different diagnostic tests are outlined, as well as imaging studies such as magnetic resonance imaging and ultrasound. Misdiagnosis and delayed diagnosis of these tumours are common, while a familial tendency is a potential risk factor but not yet proven. Complete surgical excision often results in complete symptomatic relief, while recurrences are largely due to incomplete excision or the growth of a new glomus tumour. This article aims to review the key aspects of glomus tumours and provide a diagnostic algorithm so that the lesion can be recognized and treated earlier.

  • Fractures at the lateral end of the clavicle inevitably require surgical treatment as there is high potential for delayed union or nonunion. Acromioclavicular dislocation also requires stable and solid fixation for healing, and surgical treatment is recommended for the maintenance of joint function. The hook plate maintains the biomechanics of the acromioclavicular joint, enabling early range of motion. Therefore, for the past 10 years, the hook plate has been widely used in distal clavicle fractures and acromioclavicular joint injuries. However, the hook plate is associated with several complications, such as proximal clavicle fractures, widening of the hook hole, rotator cuff tear, subacromial impingement, and often acromial fractures. We report on two unusual cases of acromion fracture after hook plate fixation in patients with distal clavicle fracture and acromioclavicular dislocation alongside a literature review.
