1Fruit quality,anthocyanin and total phenolic contents,and antioxidant activities of 45 blueberry cultivars grown in Suwon,Korea显示文摘Blueberry fruits from 45 commercial cultivars (39 northern highbush and 6 half highbush blueberry) grown in Suwon,Korea were analyzed for fruit size,soluble solids content,titratable acidity,total anthocyanin content,total phenolic content,and antioxidant activity.Fruit characteristics varied widely among the 45 blueberry cultivars.Fruit weight ranged from 0.9 to 3.6 g,soluble solids content from 8.3 to 14.3 °Brix,and titratable acidity from 0.8% to 3.6%.Antioxidant activity ranged from 0.7 to 2.1 mg of quercetin equivalents per gram of fresh berries in different blueberry cultivars.Among the 45 blueberry cultivars,high amounts of anthocyanins and polyphenols,and high antioxidant activity were observed in 'Elliott','Rubel','Rancocas',and 'Friendship'.Jin Gook KIM Hong Lim KIM Su Jin KIM Kyo-Sun PARK 2013Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2013,14,9:20
2Treatment strategies using adefovir dipivoxil for individuals with lamivudine-resistant chronic hepatitis B显示文摘AIM:To investigate retrospectively the long-term efficacy of various treatment strategies using adefovir dipivoxil(adefovir) in patients with lamivudine-resistant chronic hepatitis B.METHODS:We included 154 consecutive patients in two treatment groups:the 'add-on' group(n = 79),in which adefovir was added to ongoing lamivudine treatment due to lamivudine resistance,and the 'switch/combination' group(n = 75),in which lamivudine was first switched to adefovir and then re-added later as needed.The 'switch/combination' group was then divided into two subgroups depending on whether participants followed(group A,n = 30) or violated(group B,n = 45) a proposed treatment strategy that determined whether to add lamivudine based on the serum hepatitis B virus(HBV) DNA levels(< 60 IU/mL or not) after 6 mo of treatment(roadmap concept).RESULTS:The cumulative probability of virologic response(HBV DNA < 60 IU/mL) was higher in group A than in the 'add-on' group and in group B(P < 0.001).In contrast,the cumulative probability of virologic breakthrough was lower in the 'add-on' group than in group B(P = 0.002).Furthermore,the risk of virologic breakthrough in the multivariate analysis was significantly lower in the 'add-on' group than in group A(hazard ratio = 0.096;95%CI,0.015-0.629;P = 0.015).CONCLUSION:The selective combination of adefovir with lamivudine based upon early treatment responses increased the odds of virologic breakthrough relative to the use of uniform combination therapy from the beginning of treatment.Tae Jung Yun Jin Yong Jung Chang Ha Kim Soon Ho Um Hyonggin An Yeon Seok Seo Jin Dong Kim Hyung Joon Yim Bora Keum Yong Sik Kim Yoon Tae Jeen Hong Sik Lee Hoon Jai Chun Chang Duck Kim Ho Sang Ryu 2012World Journal of Gastroenterology2012,18,47:19
3Connection between inflammation and carcinogenesis in gastrointestinal tract: Focus on TGF-β signaling显示文摘Inflammation is a primary defense process against various extracellular stimuli,such as viruses,pathogens,foods,and environmental pollutants.When cells respond to stimuli for short periods of time,it results in acute or physiological inflammation.However,if the stimulation is sustained for longer time or a pathological state occurs,it is known as chronic or pathological inflammation.Several studies have shown that tumorigenesis in the gastrointestinal (GI) tract is closely associated with chronic inflammation,for which abnormal cellular alterations that accompany chronic inflammation such as oxidative stresses,gene mutations,epigenetic changes,and inflammatory cytokines,are shared with carcinogenic processes,which forms a critical cross-link between chronic inflammation and carcinogenesis.Transforming growth factor (TGF)-β is a multi-potent cytokine that plays an important role in regulation of cell growth,apoptosis and differentiation.Most importantly,TGF-β is a strong anti-inflammatory cytokine that regulates the development of effector cells.TGF-β has a suppressive effect on carcinogenesis under normal conditions by inhibiting abnormal cell growth,but on the other hand,many GI cancers originate from uncontrolled cell growth and differentiation by genetic loss of TGF-β signaling molecules or perturbation of TGF-β adaptors.Once a tumor has developed,TGF-β exerts a promoting effect on the tumor itself and stromal cells to enhance cell growth,alter the responsiveness of tumor cells to stimulate invasion and metastasis,and inhibited immune surveillance.Therefore,novel development of therapeutic agents to inhibit TGF-β-induced progression of tumor and to retain its growth inhibitory activities,in addition to anti-inflammatory actions,could be useful in oncology.In this review,we discuss the role of TGF-β in inflammation and carcinogenesis of the GI tract related to abnormal TGF-β signaling.Suntaek Hong Ho-Jae Lee Seong Jin Kim Ki-Baik Hahm 2010World Journal of Gastroenterology2010,16,17:18
4Recurrence after endoscopic piecemeal mucosal resection for large sessile colorectal polyps显示文摘AIM: To evaluate the safety and outcomes of endoscopic piecemeal mucosal resection (EPMR) for large sessile colorectal polyps. METHODS: The patients enrolled in this study were 47 patients with 50 large sessile polyps (diameter, 2 cm or greater) who underwent EPMR using a submucosal saline injection technique between December 2002 and October 2005. All medical records, including characteristics of the patients and polyps, complications, and recurrences, were retrospectively reviewed. The first follow-up endoscopic examination was performed at 3-6 mo after initial endoscopic resection, and the second at 12 mo postEPMR. Subsequent surveillance colonoscopic examinations were individualized, taking risk factors into account. RESULTS: The patients were 23 men and 24 women,with a mean age of 60 years. Mean polyp size was 30.1 mm. Of 50 polyps identified, 34 (68%) were benign and 16 (32%) were malignant. There were 6 (12%) cases with EPMR-related bleeding: 5 intra-procedural and 1 early post-procedural bleeding. All bleeding episodes were managed by endoscopic clipping or argon beam coagulation. There were no perforations. Recurrence was identified in 5 cases (12.2%): 4 local recurrences detected at 3 mo post-EPMR and 1 local recurrence detected at 14 mo post-EPMR. The recurrence rate after EPMR was 3.1% for benign polyps and 33.3% for malignant polyps (P < 0.05). Median follow-up time was 37 mo. CONCLUSION: EPMR is safe, but should be applied carefully in malignant polyps. Close follow-up endoscopic examinations are necessary for early detection of recurrence.Guh Jung Seo Dae Kyung Sohn Kyung Su Han Chang Won Hong Byung Chang Kim Ji Won Park Hyo Seong Choi Hee Jin Chang Jae Hwan Oh 2010World Journal of Gastroenterology2010,16,22:17
5The dynamics of the piglet gut microbiome during the weaning transition in association with health and nutrition显示文摘Background: Understanding the composition of the microbial community and its functional capacity during weaning is important for pig production as bacteria play important roles in the pig's health and growth performance. However,limited information is available regarding the composition and function of the gut microbiome of piglets in early-life.Therefore, we performed 16 S rRNA gene and whole metagenome shotgun sequencing of DNA from fecal samples from healthy piglets during weaning to measure microbiome shifts, and to identify the potential contribution of the early-life microbiota in shaping piglet health with a focus on microbial stress responses, carbohydrate and amino acid metabolism.Results: The analysis of 16 S rR NA genes and whole metagenome shotgun sequencing revealed significant compositional and functional differences between the fecal microbiome in nursing and weaned piglets. The fecal microbiome of the nursing piglets showed higher relative abundance of bacteria in the genus Bacteroides with abundant gene families related to the utilization of lactose and galactose. Prevotel a and Lactobacil us were enriched in weaned piglets with an enrichment for the gene families associated with carbohydrate and amino acid metabolism. In addition, an analysis of the functional capacity of the fecal microbiome showed higher abundances of genes associated with heat shock and oxidative stress in the metagenome of weaned piglets compared to nursing piglets.Conclusions: Overal, our data show that microbial shifts and changes in functional capacities of the piglet fecal microbiome resulted in potential reductions in the effects of stress, including dietary changes that occur during weaning.These results provide us with new insights into the piglet gut microbiome that contributes to the growth of the animal.Robin B.Guevarra Sang Hyun Hong Jin Ho Cho Bo-Ra Kim Jiwon Shin Jun Hyung Lee Bit Na Kang Young Hwa Kim Suphot Wattanaphansak Richard E.Isaacson Minho Song Hyeun Bum Kim 2018Journal of Animal Science and Biotechnology2018,9,4:16
6Chaga mushroom (Inonotus obliquus) induces G0/G1 arrest and apoptosis in human hepatoma HepG2 cells显示文摘AIM: To investigate the anti-proliferative and apoptotic effects of Chaga mushroom (Inonotus obliquus) water extract on human hepatoma cell lines,HepG2 and Hep3B cells. METHODS: The cytotoxicity of Chaga extract was screened by 3-4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide (MTT) assay. Morphological observation,flow cytometry analysis,Western blot were employed to elucidate the cytotoxic mechanism of Chaga extract. RESULTS: HepG2 cells were more sensitive to Chaga extract than Hep3B cells,as demonstrated by markedly reduced cell viability. Chaga extract inhibited the cell growth in a dose-dependent manner,which was accompanied with G0/G1-phase arrest and apoptotic cell death. In addition,G0/G1 arrest in the cell cycle was closely associated with down-regulation of p53,pRb,p27,cyclins D1,D2,E,cyclin-dependent kinase (Cdk) 2,Cdk4,and Cdk6 expression. CONCLUSION: Chaga mushroom may provide a new therapeutic option,as a potential anticancer agent,in the treatment of hepatoma.Myung-Ja Youn Jin-Kyung Kim Seong-Yeol Park Yunha Kim Se-Jin Kim Jin Seok Lee Kyu Yun Chai Hye-Jung Kim Ming-Xun Cui Hong Seob So Ki-Young Kim Raekil Park 2008World Journal of Gastroenterology2008,14,4:13
7Endoscopic papillary large balloon dilation for the removal of bile duct stones显示文摘Endoscopic papillary large balloon dilation(EPLBD)with endoscopic sphincterotomy(EST)has been widely used as the alternative to EST along with endoscopic mechanical lithotripsy(EML)for the removal of large or difficult bile duct stones.Furthermore,EPLBD without EST was recently introduced as its simplified alternative technique.Thus,we systematically searched PubMed,Medline,the Cochrane Library and EMBASE,and analyzed all gathered data of EPLBD with and without EST,respectively,by using a single standardized definition,reviewing relevant literatures,published between 2003and June 2013,where it was performed with largediameter balloons(12-20 mm).The outcomes,including the initial success rate,the rate of needs for EML,and the overall success rate,and adverse events were assessed in each and compared between both of two procedures:'EPLBD with EST'and'EPLBD without EST'.A total of 2511 procedures from 30 published articles were included in EPLBD with EST,while a total of413 procedures from 3 published articles were included in EPLBD without EST.In the results of outcomes,the overall success rate was 96.5%in EPLBD with EST and97.2%in EPLBD without EST,showing no significant difference between both of them.The initial success rate(84.0%vs 76.2%,P<0.001)and the success rate of EPLBD without EML(83.2%vs 76.7%,P=0.001)was significantly higher,while the rate of use of EML was significantly lower(14.1%vs 21.6%,P<0.001),in EPLBD with EST.The rate of overall adverse events,pancreatitis,bleeding,perforation,other adverse events,surgery for adverse events,and fatal adverse events were 8.3%,2.4%,3.6%,0.6%,1.7%,0.2%and 0.2%in EPLBD with EST and 7.0%,3.9%,1.9%,0.5%,0.7%,0%and 0%in EPLBD without EST,respectively,showing no significant difference between both of them.In conclusion,recent accumulated results of EPLBD with or even without EST suggest that it is a safe and effective procedure for the removal of large or difficult bile duct stones without any additional risk of severe adverse events,when performed under appropriate guidelines.Jin Hong Kim Min Jae Yang Jae Chul Hwang Byung Moo Yoo 2013World Journal of Gastroenterology2013,19,46:12
8Prognostic value of inflammation-based markers in patients with pancreatic cancer administered gemcitabine and erlotinib显示文摘AIM: To evaluate the value of systemic inflammationbased markers as prognostic factors for advanced pancreatic cancer(PC). METHODS: Data from 82 patients who underwent combination chemotherapy with gemcitabine and erlotinib for PC from 2011 to 2014 were collected retrospectively. Data that included the neutrophil-to-lymphocyte ratio(NLR), the platelet-to-lymphocyte ratio, and the C-reactive protein(CRP)-to-albumin(CRP/Alb) ratio were analyzed. Kaplan-Meier curves, and univariate and multivariate Cox proportional hazards regression analyses were used to identify the prognostic factors associated with progression-free survival(PFS) and overall survival(OS). RESULTS: The univariate analysis demonstrated the prognostic value of the NLR(P = 0.049) and the CRP/Alb ratio(P = 0.047) in relation to PFS, and a positiverelationship between an increase in inflammation-based markers and a poor prognosis in relation to OS. The multivariate analysis determined that an increased NLR(hazard ratio = 2.76, 95%CI: 1.33-5.75, P = 0.007) is an independent prognostic factor for poor OS. There was no association between the PLR and the patients' prognoses in those who had received chemotherapy that comprised gemcitabine and erlotinib in combination. The Kaplan-Meier method and the log-rank test determined significantly worse outcomes in relation to PFS and OS in patients with an NLR > 5 or a CRP/Alb ratio > 5.CONCLUSION: Systemic inflammation-based markers, including increases in the NLR and the CRP/Alb ratio, may be useful for predicting PC prognoses.Jae Min Lee Hong Sik Lee Jong Jin Hyun Hyuk Soon Choi Eun Sun Kim Bora Keum Yeon Seok Seo Yoon Tae Jeen Hoon Jai Chun Soon Ho Um Chang Duck Kim 2016World Journal of Gastrointestinal Oncology2016,8,7:12
9Role of surgical resection for multiple hepatocellular carcinomas显示文摘AIM:To clarify the role of surgical resection for multiple hepatocellular carcinomas(HCCs)compared to transarterial chemoembolization(TACE)and liver transplantation(LT). METHODS:Among the HCC patients who were managed at Yonsei University Health System between January 2003 and December 2008,160 patients who met the following criteria were retrospectively enrolled:(1) two or three radiologically diagnosed HCCs;(2)no radiologic vascular invasion;(3)Child-Pugh class A;(4) main tumor smaller than 5 cm in diameter;and(5) platelet count greater than 50 000/mm3.Long-term outcomes were compared among the following three treatment modalities:surgical resection or combined radiofrequency ablation(RFA)(n=36),TACE(n=107), and LT(n=17).The survival curves were computed using the Kaplan-Meier method and compared with a log-rank test.To identify the patients who gained a survival benefit from surgical resection,we also investigated prognostic factors for survival following surgical resection.Multivariate analyses of the prognostic factors for survival were performed using the Cox proportional hazard model. RESULTS:The overall survival(OS)rate was significantly higher in the surgical resection group than in the TACE group(48.1%vs 28.9%at 5 years,P<0.005). LT had the best OS rate,which was better than that of the surgical resection group,although the difference was not statistically significant(80.2%vs 48.1%at 5 years,P=0.447).The disease-free survival rates were also significantly higher in the LT group than in the surgical resection group(88.2%vs 11.2%at 5 years, P<0.001).Liver cirrhosis was the only significant prognostic factor for poor OS after surgical resection. Clinical liver cirrhosis rates were 55.6%(20/36)in the resection group and 93.5%(100/107)in the TACE group.There were 19 major and 17 minor resections. En bloc resection was performed in 23 patients,multisite resection was performed in 5 patients,and combined resection with RFA was performed in 8 patients. In the TACE group,only 34 patients(31.8%)were recorded as having complete remission after primary TACE.Seventy-two patients(67.3%)were retreated with repeated TACE combined with other therapies. In patients who underwent surgical resection,the 16 patients who did not have cirrhosis had higher 5-year OS and disease-free survival rates than the 20 patients who had cirrhosis(80.8%vs 25.5%5-year OS rate, P=0.006;22.2%vs 0%5-year disease-free survival rate,P=0.048).Surgical resection in the 20 patients who had cirrhosis did not provide any survival benefit when compared with TACE(25.5%vs 24.7%5-year OS rate,P=0.225).Twenty-nine of the 36 patients who underwent surgical resection experienced recur-rence.Of the patients with cirrhosis,80%(16/20) were within the Milan criteria at the time of recurrence CONCLUSION:Among patients with two or three HCCs, no radiologic vascular invasion,and tumor diameters≤ 5 cm,surgical resection is recommended only in those without cirrhosis.Sung Hoon Choi Gi Hong Choi Seung Up Kim Jun Yong Park Dong Jin Joo Man Ki Ju Myoung Soo Kim Jin Sub Choi Kwang Hyub Han Soon Il Kim 2013World Journal of Gastroenterology2013,19,3:12
10Anti-inflammatory and Antimicrobial Effects of Anthocyanin Extracted from Black Soybean on Chronic Bacterial Prostatitis Rat Model显示文摘Objective: To investigated the anti-inflammatory and antimicrobial effects of anthocyanins extracted from black soybean on the chronic bacterial prostatitis(CBP) rat model.Methods: The SpragueDawley rats were divided into 4 groups,including control,ciprofloxacin,anthocyanins and anthocyanins with ciprofloxacin groups(n=8 in each group).Then,drip infusion of bacterial suspension(Escherichia coli Z17O_2:K_1:H^-) into Sprague-Dawley rats was conducted to induce CBP.In 4 weeks,results of prostate tissue,urine culture,and histological analysis on the prostate were analyzed for each group.Results: The use of ciprofloxacin,anthocyanins,and anthocyanins with ciprofloxacin showed statistically significant decreases in bacterial growth and improvements in the reduction of prostatic inflammation compared with the control group(P<0.05).The anthocyanins with ciprofloxacin group showed a statistically significant decrease in bacterial growth and improvement in prostatic inflammation compared with the ciprofloxacin group(P<0.05).Conclusions: These results suggest that anthocyanins may have anti-inflammatory and antimicrobial effects,as well as a synergistic effect with ciprofloxacin.Therefore,we suggest that the combination of anthocyanins and ciprofloxacin may be effective in treating CBP to obtain a higher rate of treatment success.Byung Il Yoon Woong Jin Bae Yong Sun Choi Su Jin Kim U Syn Ha Sung-Hoo Hong Dong Wan Sohn Sae Woong Kim 2018Chinese Journal of Integrative Medicine2018,24,8:11
11Diagnostic value for extrahepatic metastases of hepatocellular carcinoma in positron emission tomography/computed tomography scan显示文摘AIM: To evaluated the value of 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) scan in diagnosis of hepatocellular carcinoma (HCC) and extrahepatic metastases. METHODS: A total of 138 patients with HCC who had both conventional imaging modalities and 18F-FDG PET/CT scan done between November 2006 and March 2011 were enrolled. Diagnostic value of each imaging modality for detection of extrahepatic metastases was evaluated. Clinical factors and tumor characteristics including PET imaging were analyzed as indicative factors for metastases by univariate and multivariate methods. RESULTS: The accuracy of chest CT was significantly superior compared with the accuracy of PET imaging for detecting lung metastases. The detection rate of metastatic pulmonary nodule ≥ 1 cm was 12/13 (92.3%), when < 1 cm was 2/10 (20%) in PET imaging. The accuracy of PET imaging was significantly superior compared with the accuracy of bone scan for detecting bone metastases. In multivariate analy- sis, increased tumor size (≥ 5 cm) (P = 0.042) and increased average standardized uptake value (SUV) uptake (P = 0.028) were predictive factors for extrahepatic metastases. Isometabolic HCC in PET imaging was inversely correlated in multivariate analysis (P = 0.035). According to the receiver operating characteristic curve, the optimal cutoff of average SUV to predict extrahepatic metastases was 3.4. CONCLUSION: 18F-FDG PET/CT scan is invaluable for detection of lung metastases larger than 1 cm and bone metastases. Primary HCC having larger than 5 cm and increased average SUV uptake more than 3.4 should be considered for extrahepatic metastases.Ji Eun Lee Jae Young Jang Soung Won Jeong Sae Hwan Lee Sang Gyune Kim Sang-Woo Cha Young Seok Kim Young Deok Cho Hong Soo Kim Boo Sung Kim So Young Jin Deuk Lin Choi 2012World Journal of Gastroenterology2012,18,23:10
12Surgical outcome of pancreatic cancer using radical antegrade modular pancreatosplenectomy procedure显示文摘AIM:To evaluate the surgical outcomes following radical antegrade modular pancreatosplenectomy (RAMPS) for pancreatic cancer. METHODS:Twenty-four patients underwent RAMPS with curative intent between January 2005 and June 2009 at the National Cancer Center, South Korea. Clinicopathologic data, including age, sex, operative findings, pathologic results, adjuvant therapy, postop-erative clinical course and follow-up data were retro-spectively collected and analyzed for this study. RESULTS:Twenty-one patients (87.5%) underwent distal pancreatectomy and 3 patients (12.5%) underwent total pancreatectomy using RAMPS. Nine patients (37.5%) underwent combined vessel resection, including 8 superior mesenteric-portal vein resections and 1 celiac axis resection. Two patients (8.3%) underwent combined resection of other organs, including the colon, stomach or duodenum. Negative tangential margins were achieved in 22 patients (91.7%). The mean tumor diameter for all patients was 4.09 ± 2.15 cm. The 2 patients with positive margins had a mean diameter of 7.25 cm. The mean number of retrieved lymph nodes was 20.92 ± 11.24 and the node positivity rate was 70.8%. The median survival of the 24 patients was 18.23 ± 6.02 mo. Patients with negative margins had a median survival of 21.80 ± 5.30 mo and those with positive margins had a median survival of 6.47 mo (P = 0.021). Nine patients (37.5%) had postoperative complications, but there were no postoperative mortalities. Pancreatic fistula occurred in 4 patients (16.7%):2 patients had a grade A fistula and 2 had a grade B fistula. On univariate analysis, histologic grade, positive tangential margin, pancreatic fistula and adjuvant therapy were significant prognostic factors for survival. CONCLUSION:RAMPS is a feasible procedure for achieving negative tangential margins in patients with carcinoma of the body and tail of the pancreas.Ye Rim Chang Sung-Sik Han Sang-Jae Park Seung Duk Lee Tae Suk Yoo Young-Kyu Kim Tae Hyun Kim Sang Myung Woo Woo Jin Lee Eun Kyung Hong 2012World Journal of Gastroenterology2012,18,39:9
13Outcome after endoscopic submucosal dissection for early gastric cancer in Korea显示文摘Endoscopic treatment,such as endoscopic mucosal resection(EMR) and endoscopic submucosal dissection(ESD),has been established as one of the treatment options for selected cases with early gastric cancer(EGC).Most studies on this topic have been carried out by researchers in Japan.Recently,the experience in EMR/ESD for EGC outside Japan is increasingly reported.In Korea,gastric cancer is the most common malignant disease,and the second leading cause of cancer death.Currently,EMR for EGC is widely performed in many centers in Korea.Early results with a shortterm follow-up period are very promising in Korea.Thecomplete resection rate of EMR was 37.8%-94.3%,and that of ESD was 77.4%-93.1%.In this review,we will provide an overview of the outcomes of endoscopic treatments in Korea.Jun Haeng Lee Su Jin Hong Jae Young Jang Seong Eun Kim Sang Young Seol 2011World Journal of Gastroenterology2011,17,31:8

17PD-1 blockade-unresponsive human tumor-infiltrating CD8^(+)T cells are marked by loss of CD28 expression and rescued by IL-15显示文摘Blockade of programmed death-1(PD-1)reinvigorates exhausted CD8^(+)T cells,resulting in tumor regression in cancer patients.Recently,reinvigoration of exhausted CD8^(+)T cells following PD-1 blockade was shown to be CD28-dependent in mouse models.Herein,we examined the role of CD28 in anti-PD-1 antibody-induced human T cell reinvigoration using tumor-infiltrating CD8^(+)T cells(CD8^(+)TILs)obtained from non-small-cell lung cancer patients.Single-cell analysis demonstrated a distinct expression pattern of CD28 between mouse and human CD8^(+)TILs.Furthermore,we found that human CD28^(+)CD8^(+)but not CD28^(–)CD8^(+)TILs responded to PD-1 blockade irrespective of B7/CD28 blockade,indicating that CD28 costimulation in human CD8^(+)TILs is dispensable for PD-1 blockade-induced reinvigoration and that loss of CD28 expression serves as a marker of anti-PD-1 antibody-unresponsive CD8^(+)TILs.Transcriptionally and phenotypically,PD-1 blockade-unresponsive human CD28^(–)PD-1^(+)CD8^(+)TILs exhibited characteristics of terminally exhausted CD8^(+)T cells with low TCF1 expression.Notably,CD28^(–)PD-1^(+)CD8^(+)TILs had preserved machinery to respond to IL-15,and IL-15 treatment enhanced the proliferation of CD28^(–)PD-1^(+)CD8^(+)TILs as well as CD28^(+)PD-1^(+)CD8^(+)TILs.Taken together,these results show that loss of CD28 expression is a marker of PD-1 blockade-unresponsive human CD8^(+)TILs with a TCF1–signature and provide mechanistic insights into combining IL-15 with anti-PD-1 antibodies.Kyung Hwan Kim Hong Kwan Kim Hyung-Don Kim Chang Gon Kim Hoyoung Lee Ji Won Han Seong Jin Choi Seongju Jeong Minwoo Jeon Hyunglae Kim Jiae Koh Bo Mi Ku Su-Hyung Park Myung-Ju Ahn Eui-Cheol Shin 2021Cellular & Molecular Immunology2021,18,2:6
18Variation in Summer Surface Air Temperature over Northeast Asia and Its Associated Circulation Anomalies显示文摘This study investigates the interannual variation of summer surface air temperature over Northeast Asia(NEA) and its associated circulation anomalies.Two leading modes for the temperature variability over NEA are obtained by EOF analysis.The first EOF mode is characterized by a homogeneous temperature anomaly over NEA and therefore is called the NEA mode.This anomaly extends from southeast of Lake Baikal to Japan,with a central area in Northeast China.The second EOF mode is characterized by a seesaw pattern,showing a contrasting distribution between East Asia(specifically including the Changbai Mountains in Northeast China,Korea,and Japan) and north of this region.This mode is named the East Asia(EA) mode.Both modes contribute equivalently to the temperature variability in EA.The two leading modes are associated with different circulation anomalies.A warm NEA mode is associated with a positive geopotential height anomaly over NEA and thus a weakened upper-tropospheric westerly jet.On the other hand,a warm EA mode is related to a positive height anomaly over EA and a northward displaced jet.In addition,the NEA mode tends to be related to the Eurasian teleconnection pattern,while the EA mode is associated with the East Asia-Pacific/PacificJapan pattern.Wei CHEN Xiaowei HONG Riyu LU Aifen JIN Shizhu JIN Jae-Cheol NAM Jin-Ho SHIN Tae-Young GOO Baek-Jo KIM 2016Advances in Atmospheric Sciences2016,33,1:6
19How to improve patient satisfaction during midazolam sedation for gastrointestinal endoscopy?显示文摘AIM To determine the procedure-related factors that affect sedation satisfaction and to make a suggestion to improve it.METHODS We prospectively enrolled a total of 456 patients who underwent outpatient endoscopy procedures with midazolam sedation between March 2014 and August 2014. All patients completed both pre- and postendoscopy questionnaires about sedation expectations and satisfaction. RESULTS The study cohort included 167 (36.6%) patients whounderwent esophagogastroduodenoscopy (EGD), 167 (36.6%) who underwent colonoscopy, and 122(26.8%) who underwent a combined procedure (EGD and colonoscopy). Over 80% of all patients were satisfied with sedation using midazolam. In univariate and multivariate analyses, total procedure time in the EGD group, younger age (≤ 50 years), and longer colonoscopy withdrawal time in the colonoscopy group were related to decreased satisfaction with sedation. However, in active monitoring and intervention group, there was no decrease in grade of satisfaction despite longer procedure time due to more procedures during colonoscopy. Younger age (≤ 50 years), longer interprocedure time gap, and colonoscopy withdrawal time were related to decreased satisfaction in the combined EGD and colonoscopy group. CONCLUSION Midazolam is still a safe and effective sedative for gastrointestinal endoscopy. Satisfaction with sedation depends on several factors including age(≤ 50 years) and procedure time duration. To improve patient satisfaction with sedation, active monitoring of sedation status by the endoscopist should be considered for patients who require long procedure time.Eun Hyo Jin Kyoung Sup Hong Young Lee Ji Yeon Seo Ji Min Choi Jaeyoung Chun Sang Gyun Kim Joo Sung Kim Hyun Chae Jung 2017World Journal of Gastroenterology2017,23,6:6
20Preparation and Characterization of Porous PVdF-HFP/clay Nanocomposite Membranes显示文摘Polyvinylidene fluoride-hexafluoropropylene (PVdF-HFP) / clay nanocomposite membranes were prepared by phase inversion method through controlling retention time to apply for a lithium ion secondary batteries. Increased membrane porosity with macrovoids was observed at increasing retention time. Partially intercalated structures of PVdF-HFP/clay nanocomposite membranes were confirmed by X-ray diffraction (XRD) analysis. PVdF-HFP membranes containing various kind of clay showed the increase of membrane modulus compared to the pristine PVdF-HFP membrane.Mi Jin Koh Hae Young Hwang Deuk Ju Kim Hyeng Jun Kim Young Taik Hong Sang Yong Nam 2010Journal of Materials Science & Technology2010,26,7:5
