Abstract
Anoctamin 1 (ANO1), a calcium-activated chloride channel, is highly expressed and amplified in a number of carcinomas including breast, pancreatic and prostate cancers. Downregulation of ANO1 expression and function significantly inhibits cell proliferation, migration, and invasion of various cancer cell lines. Development of potent and selective ANO1 inhibitors is currently desirable, which may provide a new strategy for cancer treatment. Our previous study revealed a new class of ANO1 inhibitor, (E)-2-(4-chloro-2-methylphenoxy)-N'-(2-methoxybenzylidene)acetohydrazide (Ani9) and structural optimization via chemical modification of Ani9 basic skeleton was undertaken for the development of more potent and specific inhibitors of ANO1. Structure-activity relationship studies with newly synthesized derivatives revealed a number of potent ANO1 inhibitors, among which 5f is the most potent inhibitor with an IC50 value of 22 nM. The selectivity analyses showed that 5f has excellent selectivity to ANO1 (>1000-fold over ANO2). In cellular assays, 5f significantly inhibited cell proliferation of PC3, MCF7, and BxPC3 cells expressing high levels of ANO1. In addition, 5f strongly reduced the protein levels of ANO1 in PC3 cells. This study will be useful in the development of ANO1 inhibitors for treatment of cancer and other ANO1-related diseases.

Abstract
Raynaud's disease is a medical condition in which arterial spasm causes episodes of reduced blood flow, in the setting of certain triggers such as cold weather. Patients with this condition are at risk of adverse reactions if they receive medications with vasoactive properties. Methylergonovine maleate is one drug used during cesarean delivery to treat postpartum hemorrhage due to uterine atony. By acting directly on uterine and vascular smooth muscle, it produces cardiovascular responses such as coronary vasospasm, myocardial infarction, and even cardiac arrest. However, pulmonary events have rarely been reported. We report our anesthetic management of a 36-year-old patient, with undiagnosed Raynaud's disease and undergoing cesarean delivery, who experienced new onset acute pulmonary edema after methylergonovine administration to manage postpartum hemorrhage.

Abstract
In a previous study, we have demonstrated that S-methylmethionine sulfonium (SMMS) confers wound-healing and photoprotective effects on the skin, suggesting that SMMS can be used as a cosmetic raw material. However, it has an unpleasant odor. Therefore, in the present study, we synthesized odor-free SMMS derivatives by eliminating dimethyl sulfide, which is the cause of the unpleasant odor and identified two derivatives that exhibited skin-protective effects: one derivative comprised (2S,4S)- and (2R,4S)-2-phenylthiazolidine-4-carboxylic acid and the other comprised (2S,4R)-, (2S,4S)-, (2R,4R)-, and (2R,4S)-2-phenyl-1,3-thiazinane-4-carboxylic acid. We performed in vitro proliferation assays using human dermal fibroblasts (hDFs) and an immortalized human keratinocyte cell line (HaCaT). The two SMMS derivatives were shown to increase hDF and HaCaT cell proliferation as well as improve their survival by protecting against ultraviolet exposure. Moreover, the derivatives regulated the expression of collagen type I and MMP mRNAs against ultraviolet exposure in hDFs, suggesting that these derivatives can be developed as cosmetic raw materials.

Abstract
UNLABELLED Patients with Parkinson's disease (PD) were at higher risk of osteoporotic vertebral compression fractures (OVCF) compared to controls and had elevated mortality rates. Compared to conservative treatment, surgical treatment for OVCF in PD patients seemed to be associated with better outcomes. INTRODUCTION The purpose of this study was to evaluate the risk of OVCF in patients with PD. METHODS Data from patients over the age of 60 years who were diagnosed with PD were collected between 2004 and 2013 from the Korean National Health Insurance Database (n = 3370). The comparison group (non-PD) consisted of randomly selected patients (five per patient with PD; n = 16,850) matched to the PD group, who were newly diagnosed annually according to age and sex. Cox proportional hazard regressions were used to examine the relationships between osteoporosis, OVCF, surgery for OVCF, and PD. Household income and residential area of patients were also assessed. Overall survival rates were calculated after adjusting for confounding factors, such as hypertension, diabetes mellitus, and chronic kidney disease. RESULTS OVCF was developed in 12.5% of patients in the PD group and in 7.4% of patients in the control group. PD was associated with increased risk of osteoporosis (hazard ratio [HR], 1.32; 95% confidence interval [CI], 1.21-1.43; p < 0.001), OVCF (HR 1.66; 95% CI, 1.47-1.87; p < 0.001), and surgery for OVCF (HR 2.69; 95% CI, 1.78-4.08; p < 0.001). Household income was not significantly related with development of osteoporosis, incidence of OVCF, or surgery for OVCF. Residential area was statistically associated with osteoporosis, OVCF, and surgery for OVCF. The mortality rate of the PD group was about 1.7 times higher than that of the non-PD group after adjusting for potential confounders, and the mortality rate of the PD with OVCF group was higher than that of the non-PD group, but not significantly (p = 0.09). The survival rate of the PD group with surgery for OVCF showed a trend toward a more positive prognosis compared with that of the PD group with conservative treatment. CONCLUSIONS Patients with PD had significantly increased risk of osteoporosis and OVCF. Surgical treatment for OVCF in PD patients was associated with a better prognosis than conservative treatment.

Abstract
Serum levels of several commonly measured enzymes are abnormal in patients with end-stage renal disease (ESRD). In the present study we measured serum total LDH activity and LDH isoenzymes in a group of 25 ESRD patients shortly before, during, and immediately after hemodialysis. Baseline serum total LDH activity in the ESRD group was midly but significantly higher than that found in the normal control group. The observed elevation was associated with an isomorphic pattern. Single passage of blood through the extracorporeal apparatus led to a rise in total LDH, LDH-3, LDH-2 and LDH-4, a pattern consistent with release from the platelets. A steady increase was noted in total LDH, LDH-5 and LDH-1 of arterial blood during hemodialysis. This was thought to be due to ultrafiltration-induced hemoconcentration, enzyme release from the formed elements within the extracorporeal circuit and complement-mediated leukocyte activation and pulmonary leukostasis. These observations should be taken into consideration with regards to interpretation of LDH and LDH isoenzyme values and proper time of blood sampling in ESRD patients.

Abstract
A new electromechanical moving-actuator type total artificial heart (TAH) has been developed to solve the imbalance problem without an extra compliance chamber. A different stroke volume was achieved by the large left sac size and the asymmetry of the actuator motion referred to the center position. The left ventricle consists of a double sac with the outer sac attached to the actuator providing active diastolic filling, while the double sac of the right ventricle being free from the actuator, and having sufficient suction produced due to the rigid pump housing. The stroke volume difference between the left and right sac is compensated through the air in the interventricular space of the variable volume (VV) space. Computer simulation based on the geometrical relationships between the blood sacs and the actuator was performed to simulate the physical mechanisms of the moving-actuator type TAH. Results were then compared with the measured pressure changes in various chambers of the pump and the stroke volume differences in mock circulation test. In two acute calf experiments, the balanced left and right atrial pressures were achieved in the moving-actuator type TAH without an extra compliance chamber
