Background: The objective of this study was to estimate the carbon sequestration in soils cooperated with organic composts and bio-char during corn cultivation. Methods and Results: For the experiment, the soil texture used in this study was clay loam, and application rates of chemical fertilizer and bio-char were 230-107-190 kg·ha-1 (N-P2O5-K2O) as recommended amount after soil test and 0.2% to soil weight. The soil samples were periodically taken at every 15-day intervals during the experimental periods. The treatments consisted of cow compost, pig compost, swine digestate from aerobic digestion system, and their bio-char cooperation. For estimating soil C sequestration, it is determined by the net balance between carbon inputs and outputs during corn cultivation periods. For the experimental results, it found that applications of aerobic swine digestate, cow compost, and pig compost could sequester C by 38.9%, 82.2% and 19.7% in soil, respectively, when bio-char from rice hulls was cooperated with soil. For plant responses, application of bio-char in the corn field for carbon sequestration was not occurred the damage of corn growth. Conclusion: When bio-char from rice hulls was cooperated with soil, applications of aerobic swine digestate, cow compost, and pig compost could sequester C by 38.9%, 82.2% and 19.7% in soil, respectively. Therefore, addition of bio-char with organic composts could have a potential soil C sequestration in agricultural practices.

Revascularization of immature necrotic teeth is a reliable treatment alternative to conventional apexogenesis or apexification. In case 1, a 12-year-old boy had his necrotic, immature mandibular left second premolar treated with a revascularization technique. At a 24-month follow-up, periapical radiolucency had disappeared and thickening of the root wall was observed. In cases 2 and 3, a lO-year-old boy had his necrotic, immature, bilateral mandibular second premolars treated with the same modality. At 48-month （in case 2） and 42-month （in case 3） follow-ups, loss of periapical radiolucencies and increases in the root wall thickness were also observed.

World Journal of Gastroenterology 2008年第24期14卷 3884-3890页

作者： Soong Lee seung-Cheol Son Moon-Jong Han Woo-Jin Kim Soo-Hyun Kim Hye-Ran Kim Woo-Kyu Jeon Ki-Hong Park Myung-Geun shin Department of Internal Medicine College of MedicineSeonam University and Seonam University Hospital Department of Laboratory Medicine Chonnam National University Medical School and Chonnam National University Hwasun Hospital Brain Korea 21 Project Center for Biomedical Human Resources at Chonnam National University Medical School Department of Internal Medicine Kangbuk Samsung HospitalSungkyunkwan University School of Medicine Korea Polymer Testing & Research Institute Ltd.

AIM： To determine intestinal permeability, the serum tumor necrosis factor （TNF）-α level and urine nitric oxide （NO） metabolites are altered in liver cirrhosis （LC） with or without ascites. METHODS： Fifty-three patients with LC and 26 healthy control subjects were enrolled in the study. The intestinal permeability value is expressed as the percentage of polyethylene glycol （PEG） 400 and 3350 retrieval in 8-h urine samples as determined by high performance liquid chromatography. Serum TNF-α concentrations and urine NO metabolites were determined using an enzyme-linked immunosorbent assay （ELISA） and Greiss reaction method, respectively. RESULTS： The intestinal permeability index wassignificantly higher in patients with LC with ascites than in healthy control subjects or patients with LC without ascites （0.88 ± 0.12 vs 0.52 ± 0.05 or 0.53 ± 0.03, P 〈 0.05） and correlated with urine nitrite excretion （r = 0.98）. Interestingly, the serum TNF-α concentration was significantly higher in LC without ascites than in control subjects or in LC with ascites （198.9 ± 55.8 pg/mL vs 40.9 ± 12.3 pg/mL or 32.1 ± 13.3 pg/mL, P 〈 0.05）. Urine nitrite excretion was significantly higher in LC with ascites than in the control subjects or in LC without ascites（ 1170.9± 28.7 μmol/L vs 903.1 ± 55.1 μmol/L or 956.7 ± 47.7 μmol/L, P 〈 0.05）. COMCLUSIOM： Increased intestinal macromolecular permeability and NO is probably of importance in the pathophysiology and progression of LC with ascites, but the serum TNF-α concentration was not related to LC with ascites.

The complex of Fas-associated factor 1 with Hsp70 stabilizes the adherens junction integrity by suppressing RhoA activation

引用

Journal of Molecular Cell Biology 2022年第6期14卷 14-29页

作者： Soonhwa Song Joon Kyu Park Sang Chui shin Jae-Jin Lee seung Kon Hong In-Kang Song Bokyung Kim Eun Joo Song Kong-Joo Lee Eunice EunKyeong Kim Graduate School of Pharmaceutical Sciences College of PharmacyEwha Womans UniversitySeoul 03760Republic of Korea Biomedical Research Institute Korea Institute of Science and Technology(KIST)Seoul 02792Republic of Korea Technology Support Center Korea Institute of Science and Technology(KIST)Seoul 02792Republic of Korea

Fas-associated factor 1 (FAF1) is a scaffolding protein that plays multiple functions, and dysregulation of FAF1 is associated withmany types of diseases such as cancers. FAF1 contains multiple ubiquitin-related domains (UBA, UBL1, UBL2, UAS, and UBX), eachdomain interacting with a specific partner. In particular, the interaction of UBL1 with heat shock protein 70 (Hsp70) is associatedwith tumor formation, although the molecular understanding remains unknown. In this study, the structural analysis revealed thatHis160 of FAF1 is important for its interaction with Hsp70. The association of Hsp70 with FAF1 is required for the interaction withIQGAP1. FAF1 negatively regulates RhoA activation by FAF1–Hsp70 complex formation, which then interacts with IQGAP1. Thesesteps play a key role in maintaining the stability of cell-to-cell junction. We conclude that FAF1 plays a critical role in the structureand function of adherens junction during tissue homeostasis and morphogenesis by suppressing RhoA activation, which induces theactivation of Rho-associated protein kinase, phosphorylation of myosin light chain, formation of actin stress fiber, and disruptionof adherens junction. In addition, depletion of FAF1 increased collective invasion in a 3D spheroid cell culture. These results provideinsightinto how the FAF1–Hsp70 complex acts as a novelregulator ofthe adherens junction integrity. The complex can be a potentialtherapeutic target to inhibit tumorigenesis and metastasis.

Objective： TO determine whether jaw-tapping movement, a classically described as an indication of personal well-being and mental health, stimulates the memory and the cognitive regions of the brain and is associated with improved brain performance. Methods： Twelve healthy right-handed female subjects completed the study. Each patient performed a jaw-tapping task and an n-back task during functional magnetic resonance imaging （fMRI）. The subjects were trained to carry out the jaw-tapping movement at home twice a day for 4 weeks. The fMRI was repeated when they returned. Results： During the first and second jaw-tapping session, both sides of precentral gyrus and the right middle frontal gyrus （BA 6） were activated. And during the second session of the jaw-tapping task, parts of frontal lobe and temporal lobe related to memory function were more activated. In addition, the total percent task accuracy in n-beck task significantly increased after 4 weeks of jaw- tapping movement. After jaw-tapping training for 4 weeks, brain areas related to memory showed significantly increased blood oxygen level dependent signals. Conclusion： Jaw-tapping movement might be a useful exercise for stimulating the memory and cognitive regions of the brain.
