To exert their beneficial effects, it is essential for the commensal bacteria of probiotic supplements to be sufficiently protected as they pass through the low pH environment of the stomach, and effectively colonize the intestinal epithelium downstream. Here, we investigated the effect of a multilayer coating containing red ginseng dietary fiber, on the acid tolerance, and the adhesion and proliferation capacities of three Lactobacillus strains (Limosilactobacillus reuteri KGC1901, Lacticaseibacillus casei KGC1201, Limosilactobacillus fermentum KGC1601) isolated from Panax ginseng, using HT-29 cells, mucin-coated plates, and human pluripotent stem cell-derived intestinal epithelial cells as in vitro models of human gut physiology. We observed that the multilayer-coated strains displayed improved survival rates after passage through gastric juice, as well as high adhesion and proliferation capacities within the various gut epithelial systems tested, compared to their uncoated counterparts. Our findings demonstrated that the multilayer coat effectively protected commensal microbiota and led to improved adhesion and colonization of intestinal epithelial cells, and consequently to higher probiotic efficacy.

Computerized Tomography is now well established and important noninvasive method of diagnosting mediastinal mass lesions because of its superior imaging of their size, location and internal composition. Authors analysed and present CT findings of 30 surgically proven mediastinal tumors and cysts that were studied and treated at the Yeungnam University Hospital during recent years. The most common tumor was thymona(9cases), and teratoma(6 cases), lymphoma(6 cases), bronchogenic cyst(4 cases), neurogenic tumor(4 cases), pericardial cyst(1 case) were next in order of frequency. There were 5 cases of thymoma showing homegenous solid density mass, 2 cases were malignant thymoma and myasthenia gravis was present in 2 cases, A case of thymolipoma and a case of thymic carcinoma were included. All teratomas were cystic masses but pathognomic fat, and calcified density were seen only in 4 cases, 5 cases were located in anterior mediastinum and 1 case was in posterior mediastinum. Lymphoma(3 Hodgkin's and 3 non-Hodgkin's) appeared as irregular lobulated mass in anterior mediastinum. Neurogenic tumor(2 ganglioneuroma and 2 neurilemmoma) appeared as homogenous density mass located in posterior mediastinum. Among the 4 bronchogenic cysts, 2 were located in retrotracheal area, I was located in subcarinal and I was in parathoracic area. One case of pericardial cyst was oval shaped cystic mass located in left pericardiac border.

Motilitone® (DA-9701) is a new herbal drug that was launched for the treatment of functional dyspepsia in December 2011 in Korea. The heterogeneous symptom pattern and multiple causes of functional dyspepsia have resulted in multiple drug target strategies for its treatment. DA-9701, a compound consisting of a combination of Corydalis Tuber and Pharbitidis Semen, has being developed for treatment of functional dyspepsia. It has multiple mechanisms of action such as fundus relaxation, visceral analgesia, and prokinetic effects. Furthermore, it was found to signifi cantly enhance meal-induced gastric accommodation and increase gastric compliance in dogs. DA-9701 also showed an analgesic effect in rats with colorectal distension induced visceral hypersensitivity and an antinociceptive effect in beagle dogs with gastric distension-induced nociception. The pharmacological effects of DA-9701 also include conventional effects, such as enhanced gastric emptying and gastrointestinal transit. The safety profi le of DA-9701 is also preferable to that of other treatments.

Purpose: The purpose of this study was to identify the effects of hyperventilation and hyperoxygenation before and after endotracheal suctioning using closed-suction system on mechanically ventilated patients. Method: We selected 20 patients who were mechanically ventilated and randomly assigned into 4 groups according to the type of treatments using repeated measure. We applied 3 types of treatment, hyperventilation, hyperoxygenation, hyperventilation+hyperoxygenation, and no treatment and measured physiologic effects-SpO_(2), HR and, mena BP. Result: There were no significant differences between the group with no treatment and the group with hyperventilation, before and after endotracheal suctioning using closed-suction system(SpO_(2)(p=.693), HR(p=.970) and mean BP(p=.638)). There were no significant differences between the group with no treatment and the group with hyperoxygenation before and after endotracheal suctioning using closed-suction system(SpO_(2)(p=.693), HR(p=.970) and mean BP(p=.638)). There were no significant differences between the group with no treatment and the group with hyperventilation hyperoxygenation before and after endotracheal suctioning using closed-suction system(SpO_(2)(p=.693), HR(P=.970) and mean BP(P=.638)). Conclusion: As the results, all of the methods, hyperventilation, hyperoxygenation, and hyperventilation hyperoxygenation can be used when nurses apply endotracheal suctioning using closed-suction systems. In case of hypoxemic patients, hyperoxygenation is recommended for prevention of deoxygenation due to endotracheal suctioning using closed-suction systems.

The treatment of solid radioactive waste can be divided into Mechanical (compaction), Thermal (Plasma), Melting (metal), Chemical (e.g. acid digestion) and Biochemical (e.g. bacteria). Among them, industrial thermal technologies include geomelt, Vitrificaion, Hip Ceramic, Incinerator, Pyrolysis, Plasma and Melting. In this study, the characteristics, status and advantages of geomelt vitrification were reviewed. Vitrification has long been considered an ideal choice for high-level radioactive waste by regulators internationally, because of its expected durability over hundreds of thousands of years. Geomelt vitrification is a highly flexible technology for hazardous and radioactive waste treatment. Uses electricity to melt waste materials to either destroy or immobilize contaminants. Final product is identical to natural obsidian very durable and resistant to weathering Geomelt vitrification creates ultra stable glass that is typically 10 times stronger than concrete, and more durable than granite or marble. Its leach resistance is among the highest of all materials in the world. In addition, contaminated soil, sludge, metals, organic matter, and bulky D&D debris can be treated simultaneously without pretreatment steps such as size reduction and sorting. Geomelt vitrification can be deployed in variety of in ground, in container or hybrid in cell treatment. Geomelt vitrification have been treating radioactive waste and hazardous waste since the 1990s, treatment in the U.S., UK, Australia, Japan and other countries. Initially developed by Pacific Northwest National Laboratory in the U.S., GeoMelt vitrification has been used successfully around the world for the U.S. Department of Energy (DOE) in Hanford and at Sellafield in the UK.
A Study on Disposal Stability of Vitrified Form
Mi-Hyun Lee,Young Hwan Hwang,Jung-Kwon Son 한국방사성폐기물학회 2023 한국방사성폐기물학회 학술논문요약집 Vol.21 No.1
Radioactive waste generated in various forms needs to be technically stabilized for safe treatment, disposal, and long-term safety. Overseas, research on vitrification with excellent mechanical and physicochemical properties of high-level waste is being actively conducted. Vitrification is a process of converting radioactive waste into a stable and durable glass-like material, which is then safe storage and disposal. The stability of vitrified form is an important concern for environment safety, as any leakage or release of radionuclide could have serious consequences for health and the environment. Therefore, several studies are being conducted on the disposal stability of vitrification of radioactive waste. In order to evaluate the stability of the solidified form, mechanical properties such as density, microhardness, and compressive strength and chemical durability such as leaching properties should be performed. There are several types of leaching test methods to evaluate the chemical durability, which is important in the characterization of solidified forms. In this study, the leaching test method for chemical durability evaluation and the evaluation results of leaching characteristics according to pH were reviewed.
