2Function-regeneration of non-porous hydrolyzed-MOF-derived materials显示文摘A facile synthetic strategy based on a water-based process is developed for the preparation of metal-organic framework (MOF)-derived materials by revisiting the hydrolyzed non-porous metal-organic frameworks (h-MOF). The poor water stability of MOF has been recognized as key limitations for its commercialization and large-scale applications because the hydrolysis resulted in the complete loss of their functionalities. However, we found that the negative effect of hydrolysis on MOF can be nullified during the heat treatment. As similar to the intact MOF, h-MOF can be used as a precursor for the preparation of MOF-derived materials from porous MOF-derived carbons (MDCs) to MDC@ZnO composites. The property of h-MOF-derived materials is almost equivalent to that of MOF-derived materials. In addition, h-MOF turned the weakness of water instability to the strength of facile water-based process for hybridization. With the demonstration of the hybrid composite between h-MDC@ZnO and reduced graphene oxide (rGO) as a prototype example, it exhibited superior electrochemical performance when evaluated as an electrode material for lithium-ion batteries.Yo Chan Jeong Jin Weon Seo Jae Ho Kim Seunghoon Nam Min Chang Shin Young Shik Cho Jin Syul Byeon Chong Rae Park Seung Jae Yang 2019Nano Research2019,12,8:5

4Radiotherapy for 65 patients with advanced unresectable hepatocellular carcinoma显示文摘AIM: To evaluate the efficacy of radiotherapy (RT) in patients with advanced unresectable hepatocellular carcinoma (HCC). METHODS: A total of 65 patients were treated with RT in the Korea University Medical Center. The median age of the patients was 60 years, and 86.2% were men. 18.5% and 81.5% of the patients were diagnosed as TNM stage Ⅲ and Ⅳ-A, respectively. Treatment response was assessed 4 mo after initiation of RT. Tumor regression rate 1 mo after initiation of RT (TRR1m) was also assessed. Duration of survival was calculated from the initiation of RT. RESULTS: The objective treatment response was 56.9%. The 12 mo survival rate was 34.7%. Predictive factors for survival were Child-Pugh grade, α-fetoprotein level and treatment response. An objective response was achieved more frequently in patients with TRR1m ≥ 20% than in those with TRR1m < 20% (P < 0.001). CONCLUSION: RT is effective in treating advanced HCC with a tumor response rate of 56.9%.Yeon Seok Seo Jin Nam Kim Bora Keum Sanghoon Park Yong Dae Kwon Yong Sik Kim Yoon Tae Jeen Hoon Jai Chun Chul Yong Kim Chang Duck Kim Ho Sang Ryu Soon Ho Um 2008World Journal of Gastroenterology2008,14,15:4
5Optimization of Propionic Acid Feeding for Production of Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) in Fed-Batch Culture of Ralstonia eutropha显示文摘The feeding method of propionic acid for production of poly (3-hydroxybutyrate-co-3-hydro xyvalerate)[P(3HB-co-3HV)]by fed-batch culture of Ralstonia eutropha was optimized to achieve high cell density and high 3HV yield,Effects of different feeding strategies of propionic acid on the production of P(3HB-co-3HV) were investigated,A decline of specific synthesis rate of copolymer and the yield of 3HV unit from propionic acid were observed due to the propionic acid accumulation in culture broth when the feeding solution with high P/G(ropionic acid to glucose) ration was employed,It was further confirmed by controlling propionic acid concentration at a low leve in the separate feeding of propionic acid.An optimed feeding strategy was demonstrated to reduce the propionic acid accumulation ,The cell concentration,P(3HB-co-3HV) productivity and 3HV unit fraction reached to 163.9 kg.m^-3,1.8kg.m^-3.h^-1,and 10.6%(by mass),respectively,resulting in a yield of 0.33g HV per g propionic acid.Longan SHANG Jin Hwan Do 范代娣 姜岷 Ho Nam CHANG 2003Chinese Journal of Chemical Engineering2003,11,2:3

8LRRK2, GBA and their interaction in the regulation of autophagy: implications on therapeutics in Parkinson’s disease显示文摘Mutations in leucine-rich repeat kinase 2 (LRRK2) and glucocerebrosidase (GBA) represent two most common genetic causes of Parkinson’s disease (PD). Both genes are important in the autophagic-lysosomal pathway (ALP), defects of which are associated with α-synuclein (α-syn) accumulation. LRRK2 regulates macroautophagy via activation of the mitogen activated protein kinase/extracellular signal regulated protein kinase (MAPK/ERK) kinase (MEK) and the calcium-dependent adenosine monophosphate (AMP)-activated protein kinase (AMPK) pathways. Phosphorylation of Rab GTPases by LRRK2 regulates lysosomal homeostasis and endosomal trafficking. Mutant LRRK2 impairs chaperone-mediated autophagy, resulting in α-syn binding and oligomerization on lysosomal membranes. Mutations in GBA reduce glucocerebrosidase (GCase) activity, leading to glucosylceramide accumulation, α-syn aggregation and broad autophagic abnormalities. LRRK2 and GBA influence each other: GCase activity is reduced in LRRK2 mutant cells, and LRRK2 kinase inhibition can alter GCase activity in GBA mutant cells. Clinically, LRRK2 G2019S mutation seems to modify the effects of GBA mutation, resulting in milder symptoms than those resulting from GBA mutation alone. However, dual mutation carriers have an increased risk of PD and earlier age of onset compared with single mutation carriers, suggesting an additive deleterious effect on the initiation of PD pathogenic processes. Crosstalk between LRRK2 and GBA in PD exists, but its exact mechanism is unclear. Drugs that inhibit LRRK2 kinase or activate GCase are showing efficacy in pre-clinical models. Since LRRK2 kinase and GCase activities are also altered in idiopathic PD (iPD), it remains to be seen if these drugs will be useful in disease modification of iPD.Shirley Yin-Yu Pang Rachel Cheuk Nam Lo Philip Wing-Lok Ho Hui-Fang Liu Eunice Eun Seo Chang Chi-Ting Leung Yasine Malki Zoe Yuen-Kiu Choi Wing Yan Wong Michelle Hiu-Wai Kung David Boyer Ramsden Shu-Leong Ho 2022Translational Neurodegeneration2022,11,1:2

11Polygonal multi-polymorphed Li4Ti5Oi2@rutile TiO2 as anodes in lithium-ion batteries显示文摘Li4Ti50i2 (LTO) has attracted considerable attention in lithium-ion battery (LIB) applications because of its favorable characteristics as an anode material. Despite its promise, the widespread use of LTO is still limited primarily due to its intrinsically poor electric and ionic con ductivities and high surface reactivity. To address these issues, we desig ned polyg onal nano architectures composed of various Li-Ti oxide crystal polymorphs by a facile synthesis route. Depending on the pH condition, this synthesis approach yields multi-polymorphed Li-Ti oxides where the interior is dominantly composed of a Li-rich phase and the exterior is a Li-deficient (or Li-free) phase. As one of these variations, a polygonal LTO-rutile TiO2 structure is formed. The rutile TiO2 on the surface of this LTO composite significantly improves the kinetics of Li^+ insertion/extraction because the channel along the o-axis in TQ2 provides a Li^+ highway due to the significantly low energy barrier for Li^+ diffusion. Moreover, the presenee of rutile TiO2, which is less reactive with a carbonate-based electrolyte, ensures Iong-term stability by suppress)ng the undesirable interfacial reaction on LTO.Chang Hyun Hwang Hee-eun Kim Inho Nam Jin Ho Bang 2019Nano Research2019,12,4:2
