  • Various skin diseases are occurring due to external factors such as urbanization and increase in environmental pollution and wearing masks due to COVID-19. Accordingly, various functional cosmetics are being released, but as some side effects are reported, research on functional cosmetics materials using natural plants is necessary. Therefore, in this study, the antioxidant, antibacterial and anti-inflammatory effects of Phyllanthus emblica, Geranium (Pelargonium graveolens), and Commiphora myrrha mixed extracts (PGC) that pharmacological efficacy has been verified were analyzed and their potential as functional cosmetics raw materials was examined. Four extracts (PGC-1~4) were prepared according to the extraction method. ABTS and DPPH radical scavenging activity experiments were conducted for the antioxidant efficacy of the extracts. In addition, paper disc experiments and LPS inflammation-inducing cytokine experiments were conducted to examine the antibacterial and anti-inflammatory effects. In addition, a cell viability test was performed to confirm cytotoxicity. As results of the study, all extracts showed antioxidant, antibacterial, and anti-inflammatory effects without cytotoxicity, and in particular, PGC-4, a fermentation and ultrasonic extract, showed the best efficacy. This means that the extraction yield of useful components varies depending on the extraction method.

  • Despite advancements in therapeutic approaches, radiotherapy and cisplatin-based chemotherapy remain primary noninvasive treatments for patients with oral squamous cell carcinoma (OSCC). Moreover, the 5-year survival rate for patients with OSCC has remained almost unchanged for several decades, and many side effects of chemotherapy still exist. In this study, three-dimensional (3D) models of OSCC were established using fibroblasts, and the efficacy of various biological inhibitors was evaluated. A culture of epithelial cells with two types of fibroblasts (hTERT-hNOFs and cancer-associated fibroblasts) within a type I collagen matrix resulted in the formation of a continuous layer of tightly packed cells compared to models without fibroblasts. Furthermore, the effects of biological chemicals, including Y27632, latrunculin A, and verteporfin, on these models were investigated. The stratified formation of the epithelial layer and invasion in OSCC 3D-culture models were effectively inhibited by verteporfin, whereas invasion was weakly inhibited by Y27632 and latrunculin. Collectively, the developed OSCC 3D-culture models established with fibroblasts demonstrated the potential for drug screening, with verteporfin showing promising efficacy.

  • Ziprasidone is equally effective as haloperidol in treating schizophrenia with fewer side effects and drug interactions. Ziprasidone is an atypical antipsychotic agent and works by blocking serotonin and dopamine receptors in the central nervous system, specifically 5-HT2A and D2 receptors. Low anticholinergic side-effects and low EPS would recommend the drug for use in the elderly. Ziprasidone inhibits reuptake of norepinephrine and serotonin at neurojunction sites in vitro, indicating a potential efficacy for depression and negative symptoms which often follow after exacerbation of schizophrenia. Patients with recent acute myocardial infarction and uncompensated heart failure are contraindicated to the drug due to a possibility of QT prolongation. Although ziprasidone is metabolized by cytochrome P450 3A4, there is no significant drug interaction with the drugs that induce or inhibit the isoenzyme. Ziprasidone is safe with coadministration of lithium and there has been no significant drug interaction reported with oral birth control pills.

  • With the progress of image-guided localization, body immobilization system, and computerized delivery of intensity-modulated radiation delivery, it became possible to perform spine radiosurgery. The next question is how to translate the high technology treatment to the clinical application. Clinical trials have been performed to demonstrate the feasibility of spine radiosurgery and efficacy of the treatment in the setting of spine metastasis, leading to the randomized trials by a cooperative group. Radiosurgery has also demonstrated its efficacy to decompress the spinal cord compression in selected group of patients. The experience indicates that spine radiosurgery has a potential to change the clinical practice in the management of spine metastasis and spinal cord compression.

  • Berberine has been used clinically for more than a decade to treat various diseases, has been shown to be effective in osteoblast differentiation, and is a potential treatment option for osteoporosis. However, compared with existing osteoporosis drugs, berberine is somewhat less effective. This study aimed to identify a new compound with efficacy superior to that of berberine. The osteogenic activities of various berberine derivatives were evaluated via cell differentiation in C2C12 preosteoblast cell lines. Alkaline phosphatase (ALP) staining assay and structure-activity relationship demonstrated that compound 2b had a potent osteogenic effect. Furthermore, compound 2b dose dependently increased ALP activity and showed no toxicity at the effective concentration, indicating its efficacy. Additionally, compound 2b upregulated BMP2-induced transcriptional activity in a promoter activity assay using ALP, BSP, and OC promoters.

  • Herbal medicines are widely used for centuries to treat illness and improve health in Asia and the use of these remedies has become a worldwide form of alternative therapy. However, there is very limited evidence from randomized controlled trials to support the efficacy of the vast majority of herbal products. Of the commonly used herbal medicines, systemic clinical experiences and promising experiments in animals have found potential evidence of efficacy for six herbal medicines (Unkei-to, Hachimijio-gan, Keishi-bukuryo-gan, Toki-shakuyaku-san, Shakuyaku-kanzo-to, Sairei-to) in the treatment for female reproductive dysfunction. Because herbs may contain potent bioactive substances, the physician should have an opportunity to outline more stringent regulation, similar to over-the counter drug.

  • This study analyzes the factors affecting user resistance to ERP in Vietnam, including the factors related to the cultural values of the users, which is rarely dealt in the previous ERP research. A research model is developed based on Klaus and Blanton [2010] and Hofstede [2011], consisting of the independent variables ('cultural value', 'system', 'organization', and 'process' related variables), a dependent variable ('user resistance to ERP') and a moderating variable ('self efficacy'). Major results of study include (1) users with high degree of uncertainty avoidance and femininity regard ERP as potential threat to their job and are likely to resist to ERP; (2) By training the users with high level of femininity to enhance their self efficacy, the degree of resistance to ERP can be reduced; (3) For ERP to be utilized successfully, systems should be developed in such a way in which working with ERP is not regarded as complex and difficult; and (4) communication and training play an important role in reducing the resistance of users.

  • Venous thromboembolism (VTE), which includes pulmonary embolism and deep vein thrombosis, is an important cause of morbidity and mortality. The aim of this review is to summarize the findings from clinically important publications over the last year in the area of VTE. In this review, we discuss 11 randomized controlled trials published from March 2013 to April 2014. The COAG and the EU-PACT trials indicate that pharmacogenetic testing has either no usefulness in the initial dosing of vitamin K antagonists or marginal usefulness in the Caucasian population. Recent clinical trials with novel oral anticoagulants (NOACs) have demonstrated that the efficacy and safety of rivaroxaban, apixaban, edoxaban, and dabigatran are not inferior to those of conventional anticoagulants for the treatment of VTE. The PEITHO and ULTIMA trials suggested that rescue thrombolysis or catheter-directed thrombolysis may maximize the clinical benefits and minimize the bleeding risk. Lastly, riociguat has a proven efficacy in treating chronic thromboembolic pulmonary hypertension. In the future, NOACs, riociguat, and catheter-directed thrombolysis have the potential to revolutionize the management of patients with VTE.

  • Obesity is a serious health concern, which has been linked to an increased risk for cardiovascular diseases and some cancers. The traditional obesity control program is expensive. Moreover, it is difficult to maintain a healthy body weight as well as reduce body fat. The long-term use of effective and tolerable medication is carefully recommended to control body weight. In addition to obesity control medications, health functional foods, related to body weight control, have become popular in the commercial market. Known mechanisms include lipolysis, appetite control, inflammation reduction, and lean body mass maintenance. Previous clinical trials have documented the efficacy of some health functional foods; however, there are limitations. Studies on the potential roles and efficacy of some health functional foods, including caffeine, green tea, protein supplement, probiotics, and arginine, were reviewed. More large-scale and randomized placebo-controlled trials should be conducted eventually.

  • The global nematicides market is expected to continue growing. With an increasing demand for synthetic chemical-free organic foods, botanical nematicides are taking the lead as replacements. Consequently, in the recent years, there have been vigorous efforts towards identification of the active secondary metabolites from various plants. These include mostly glucosinolates and their hydrolysis products such as isothiocyanates; flavonoids, alkaloids, limonoids, quassinoids, saponins, and the more recently probed essential oils, among others. And despite their overwhelming potential, variabilities in quality, efficacy, potency and composition continue to persist, and commercialization of new botanical nematicides is still lagging. Herein, we have reviewed the history of botanical nematicides and regional progresses, the potency of the identified phytochemicals from the key important plant families, and deciphered some of the impediments involved in standardization of the active compounds in addition to the concerns over the safety of the purified compounds to non-target microbial communities.
