Design and Development of Multi-treatment Flow for Salty Water of the Pickled Cabbage
( Ming-ying Chien ),( Li-cheng Hsieh ) 한국농업기계학회 2018 한국농업기계학회 학술발표논문집 Vol.23 No.1
In the process of producing pickled food, it results in high concentration of salty water. If discharged the salty water without treatments, it would cause environmental problems. A base in Dapi Township, Yunlin County, Taiwan, processing pickled cabbage, yields high concentration of salty water of 1044.48 ㎥ to 1443.84㎥ each year. There is a project of salty water treatment, expand current processing system consist of circulating pool, and crystallizing pool. For the purpose of the expanded system easy operated and steady treating, this study is focus on the control method of treatment flow of salty water. Based on the experiment data, when the relative humidity is 55%RH and the environmental temperature is 45°C, the level of salty water drops 0.5 cm every 12 hours. Additionally, there is a linear formula fitting the result to calculate daily evaporation. In conclusion, using the same setting of environment, this system is expected to treat salty water by 1 cm daily level decline per unit area, and it would be an alternative solution for the salty water in Taiwan.

Vegetable is the indispensable food for the daily life of mankind. Due to the demand for increasing the quality of vegetable in Taiwan, the protected culture must be developed for cultivation of vegetable. There are two common approaches of cultivation, including seeding and plug transplant, and both approaches require much labor. By applying the Organic Perishable Vegetable in Plugs planted, the labor problem in the past for plug seeding, sprout cultivation, transplantation and harvesting could be improved. Besides, the yield and quality could be increased. However, the short of labor is still a major problem for harvesting. This study would develop a set of harvesting machinery that is applicable for Organic Perishable Vegetable in Plugs. This could reduce the time and labor for harvesting in fields, and reach the objectives of saving of labor and increasing the productivity.

Background: Diabetic patients are at high risk of developing cancer. Traditional Chinese medicine (TCM) has become increasingly popular as an adjuvant treatment for patients with chronic diseases, and some studies have identified its beneficial effect in diabetic patients with cancer. The purpoes of this study was to outline the potential of TCM to attenuate hospitalization and mortality rates in diabetic patients with carcinoma in situ (CIS). Methods: A total of 6,987 diabetic subjects with CIS under TCM therapy were selected from the National Health Insurance Research Database of Taiwan, along with 38,800 of 1:1 sex-, age-, and index year-matched controls without TCM therapy. Cox proportional hazard analysis was conducted to compare hospitalization and mortality rates during an average of 15 years of follow-up. Results: A total of 3,999/1,393 enrolled-subjects (28.62%/9.97%) had hospitalization/mortality, including 1,777/661 in the TCM group (25.43%/9.46%) and 2,222/732 in the control group (31.80%/10.48%). Cox proportional hazard regression analysis showed a lower rate of hospitalization and mortality for subjects in the TCM group (adjusted HR=0.536; 95% CI=0.367–0.780, P<0.001; adjusted HR=0.783; 95% CI=0.574– 0.974, P = 0.022). Kaplan-Meier analysis showed that the cumulative risk of hospitalization and mortality in the case and control groups was significantly different (log rank, P<0.001 and P = 0.011, respectively). Conclusions: Diabetic patients with CIS under TCM therapy were associated with lower hospitalization and mortality rates compared to those without TCM therapy. Thus, TCM application may reduce the burden of national medical resources.

Objective: The present study is to analyze the effects of the coronavirus disease 2019 (COVID 2019) outbreak and the subsequent lockdown on the outcomes of spinal metastasis patients. Methods: The study was a retrospective analysis of data from a prospective cohort study. All patients underwent surgical intervention for spinal metastases between January 2019 and December 2021 and had at least 3 months of postoperative follow-up. The primary outcome was overall mortality during the 4 different stages (pre-COVID-19 era, COVID-19 pandemic except in Taiwan, national lockdown, lifting of the lockdown). The secondary outcomes were the oncological severity scores, medical/surgical accessibility, and patient functional outcome during the 4 periods as well as survival/mortality. Results: A total of 233 patients were included. The overall mortality rate was 41.20%. During the Taiwan lockdown, more patients received palliative surgery than other surgical methods, and no total en bloc spondylectomy was performed. The time from surgeon visit to operation was approximately doubled after the COVID-19 outbreak in Taiwan (75.97, 86.63, 168.79, and 166.91 hours in the 4 periods, respectively). The estimated survival probability was highest after the national lockdown was lifted and lowest during the lockdown. In the multivariate analysis, increased risk of mortality was observed with delay of surgery, with emergency surgery having a higher risk with delays above 33 hours, urgent surgery (below 59 and above 111 hours), and elective surgery (above 332 hours). Conclusion: The COVID-19 pandemic and related policies have altered daily clinical practice and negatively impacted the survival of patients with spinal metastases.

Objective: To investigate the effect of vascular endothelial growth factor (VEGF) and fibroblast growth factor 2 (FGF2) on revascularization, survival, and oocyte quality of cryopreserved, subcutaneously transplanted mouse ovarian tissue. Methods: Outbred ICR mice (n = 112) were used as the animal model. Vitrified mouse ovarian tissues were treated without (control group) or with VEGF and FGF2 before autologous subcutaneous transplantation. After transplantation for 2 or 3 weeks, grafts’ survival, angiogenesis, and oocyte quality were examined. Results: VEGF and FGF2 promoted revascularization and significantly increased the survival rate of subcutaneously transplanted cryopreserved ovarian tissues compared with the untreated grafted control. The two growth factors did not show long-term effects on the ovarian grafts. In contrast to the untreated ovarian grafts, active folliculogenesis was revealed as the number of various follicles was significantly higher or had an increased trend in the VEGF and FGF2-treated ones. Though the fertilization rate had no differences between VEGF/FGF2 and control group; however, the oocyte quality was much better in the VEGF/FGF2-treated grafts as demonstrated by the higher ratio of blastocyst development. Conclusions: Introducing of angiogenic factors such as VEGF and FGF2 may be a promising strategy to improve revascularization, survival, and oocyte quality of cryopreserved, subcutaneously transplanted mouse ovarian tissue.

A liquid chromatography equipped with tandem mass spectrometric method using multistage flow rates was developed for the determination of donepezil in human plasma to support a randomized, crossover bioequivalence (BE) study in which healthy volunteers each received a single oral dose of the reference and test formulations of 10 mg donepezil hydrochloride. This integrated liquid chromatography with tandem mass spectrometry (LC-MS/MS) system with electrospray ionization and a deuterium-labeled internal standard (IS) were employed for the positive multiple-reaction-monitoring (MRM) analyses. The baseline separation using a high-resolution monolithic column under gradient and flexible flowrate conditions between donepezil and multiple interfering peaks from the extracted quality control, calibration standard and study plasma samples following simple protein precipitation extraction procedures was accomplished within 1.5 minutes. The ultrafast monolithic column performance in terms of chromatographic separation efficiency, peak asymmetry and resolution and retention time reproducibility was found to be sustainable. The linear dynamic range was detected over a concentration range of 0.2–50 ng/mL. The intra- and inter-day assay accuracy and precision were within 15% for the analyte in individual biological fluids. A positive correlation coefficient (r) greater than 0.995 for donepezil concentrations in study plasma samplers measured by the proposed and the other validated LC-MS/MS methods in support of a bioequivalence study was observed.
