  • Background: Although thromboembolism is common and one of the major causes of mortality in cancer patients, maintaining therapeutic anticoagulation effect with warfarin is challenging. This study aimed to determine the prevalence and the causes of non-therapeutic INR (International Normalized Ratio) in cancer patients. Methods: Medical and pharmacy records for cancer patients managed by the pharmacist-run anticoagulation service (ACS) between May, 2010 and April, 2011 at Seoul National University Hospital were retrospectively reviewed. The causes of non-therapeutic INR were identified and compared with the results from a former study with mechanical heart valve patients. Results: A total of 335 cancer patients and 6,737 patient-visits were analyzed producing 68% (n=4,590) of non-therapeutic INR readings. Eighty-five percent of the non-therapeutic INR readings were categorized as sub-therapeutic. Frequent causes linked to non-therapeutic INR included inadequate dosage adjustment (21.8%), changes in health status (11.8%), dietary changes (8.1%), and drug interactions (4.2%). More than half of the non-therapeutic INR values had no known etiology. As causes for non-therapeutic INR, changes in health status (p<0.0001), adverse reactions (p<0.0001), and dietary changes (p=0.017) were statistically more frequent in cancer patients than in patients with mechanical heart valves. Furthermore, exposure to sub-therapeutic INR were more prevalent in cancer patients than in patients with mechanical heart valve (p<0.0001). Conclusions: This study shows that there is a tendency to keep the level of INR low and that health status change, dietary change, and drug interactions are found to be frequent causes for non-therapeutic INR in cancer patients.

  • We have investigated the effect of environmental acidity on the induction of apoptosis caused by heat and carboplatin alone or combined. The degree of apoptosis after heating at 42.5$^{\circ}C$ for 1h in pH 6.6 medium was greater than that in pH 7.5 medium in WERI human retinobalstoma cells. When heated in the same pH medium, more apoptosis occurred in the WERI cells than in the Y79 human retinoblastoma cells.(omitted)

  • Anti-cancer and therapeutic effects using therapeutic radioisotopes have been demonstrated by various studies, and it is well-known that therapeutic radioisotopes are useful in cancer treatment. Recently, one of the therapeutic radioisotopes, scandium is emerging as a radioisotope applicable to PET imaging (43Sc, 44Sc) and therapy (47Sc) in cancer theranostic approach. However, 47Sc has little known radiobiological and therapeutic efficacy compared to other therapeutic radioisotopes. Here, we investigated the quality and therapeutic efficacy of 47Sc radioisotope produced by our production/isolation technology at the research reactor 'HANARO' in KAERI (Korea Atomic Energy Research Institute). We showed that the therapeutic efficacy of 47Sc, produced by our production/isolation technology, effectively suppressed epidermal growth factor receptor (EGFR)-targeted non-small cell lung cancer (NSCLC) cells. Consequently, these results suggest that the high quality of the produced 47Sc by our production/isolation technology enables the development of therapeutic strategies for cancer treatment and radiopharmaceuticals using 47Sc.

  • Resistive therapeutic exercise prescription goal is to improve functional performance and capabilities through the development of increased muscular strengh endurance or power. Resistance can be applied to either dynamic or static muscle contractions. Resistive therapeutic exorcise can be carried nut concentrically, eccentrically, isometrically, isokinetically. Neurodevelopmental treatment has not resistive therapeutic exercise concept. But proprioceptive neuromuscular facilitate techniques have resistive therapeutic exercise concept with pattens and techniques. It is aid muscle contraction, motor control and increase strength. Manual muscle testing will help the therapist establish a qualitative and quantitative baseline level of strength. Manual resistance maybe applied a against controlled lengthening contraction re static contraction of a muscle. A repetition maximum is not easy to calculate and is not the most accurate method available today to measure strength before of after a resistive therapeutic exercise program. Oddvar Holten Diagram is essy to calculate and is the most accurate method available today to measure strength before of after a resistive therapeutic exercise program. Plyometric training emphasize the development of muscular power and coordination. Quick bursts of force in functional movement patterns are often necessary of a patient is to return to high-demand occupational, recreational or sports related activities.

  • Exosome, a type of nanoparticles also known as small extracellular vesicles are gaining attention as novel therapeutics for various diseases because of their ability to deliver genetic or bioactive molecules to recipient cells. Although many pharmaceutical companies are gradually developing exosome therapeutics, numerous hurdles remain regarding manufacture of clinical-grade exosomes for therapeutic use. In this mini-review, we will discuss the manufacturing challenges of therapeutic exosomes, including cell line development, upstream cell culture, and downstream purification process. In addition, developing proper formulations for exosome storage and, establishing good manufacturing practice facility for producing therapeutic exosomes remains as challenges for developing clinical-grade exosomes. However, owing to the lack of consensus regarding the guidelines for manufacturing therapeutic exosomes, close communication between regulators and companies is required for the successful development of exosome therapeutics. This review shares the challenges and perspectives regarding the manufacture and quality control of clinical grade exosomes.
