| 3 | Reduction of the ages at diagnosis and operation of biliary atresia in Taiwan: A 15-year population-based cohort study显示文摘AIM: To describe the ages at diagnosis and operation of biliary atresia(BA) and its incidence over a 15-year period in Taiwan.METHODS: This was a population-based cohort study. BA cases were identified from the Taiwan National Health Insurance Research Database based on the International Classification of Diseases,Ninth Revision(ICD-9) code of BA 751.61 plus Kasai operation(ICD-9 procedure code 51.37) or liver transplantation(LT,ICD-9 procedure code 50.5). The patients' characteristics including sex,age at diagnosis,age at receiving Kasai operation and age at receiving LT were compared among three birth cohorts:(1) 1997 to 2001;(2) 2002 to 2006; and(3) 2007 to 2011.RESULTS: There were a total of 540 BA cases(275 females) with an incidence of 1.62 per 10000 live births. No seasonality of BA was noted. The mean ages at diagnosis of three cohorts were 57.9,55.6 and 52.6 d.A linear regression model demonstrated a decreasing trend of the mean age at diagnosis(1.27 d per year). The proportion of BA cases that received the Kasai operation within 60 d of age increased from 76% to 81%. A total of 189(35%) BA patients underwent LT. The mean age at LT was reduced from 3-year-old to 1-year-old. The rates of LT were 25.6% and 32.3% in patients who received the Kasai operation within 60 d or after 60 d of age,respectively. All patients who did not undergo a Kasai operation eventually required LT.CONCLUSION: The ages at diagnosis and operation in BA cases have decreased over time. Kasai operation performed at younger age reduces the need for LT. The incidence of BA in Taiwan fluctuates,but without certain trend. | Jen-Shyang Lin Solomon Chih-Cheng Chen Chin-Li Lu Hung-Chang Lee Chun-Yan Yeung Wai-Tao Chan | 2015 | World Journal of Gastroenterology2015，21，46： | 10 |
| 4 | 赤霉素对甘蔗发芽和早期蔗茎生长的潜在调节作用(英文)显示文摘以甘蔗品种CoSe92423单芽为材料,在盘栽条件下研究赤霉素(GA3)对甘蔗生长特点和生化特性的影响。将甘蔗单芽分别浸入10,20,50和100mg·L-1赤霉素溶液中24h,以清水为对照,将处理的芽段种植于网室泥盘中。结果表明,低水平GA3处理(10,20,和50mg·L-1)均可刺激蔗芽生长和甘蔗植株的生长,根数、根和叶片鲜重、蔗茎鲜重、叶面积以及茎长均有所增加。与对照相比(70%),赤霉素可使蔗芽萌发早,发芽率高,其中以50mg·L-1GA3处理的发芽率最高,为90%。经赤霉素处理的甘蔗株高和茎重分别增加90%~110%、252%~282%,其中以20mg·L-1GA3处理最高。此外,赤霉素处理的蔗芽中还原糖和IAA含量也有所增加,且均以20mg·L-1GA3处理最高。因此,低水平赤霉素均对蔗芽萌发和生长具有刺激作用,但高水平赤霉素则对甘蔗生长有抑制作用。 | Radha Jain S.

| 5 | Recent progress of energy transfer and luminescence intensity boosting mechanism in Nd3+-sensitized upconversion nanoparticles显示文摘Rare earth doped upconversion nanoparticles can be considered as the spice of research in the field of luminescence nanomaterials due to their unique optical properties such as near-infrared excitation.Enormous works have been reported about biomedical applications of 980 nm excited and Yb^3+-sensitized upconversion nanoparticles.However,980 nm excitation wavelength overlaps with the absorption band of water molecules in the biological environment,leading to overheating effect that can induce thermal damages of normal cells and tissues.Recently,Nd^3+-sensitized upconversion nanoparticles which can be excited with 808 nm has been widely investigated as alternative nanoparticles that can surmount this issue of overheating effect.Even though Nd^3+-sensitized upconversion nanoparticles can reduce the overheating effect by 20 fold as compared to Yb^3+-sensitized counterpart,there are several factors that reduce the upconversion luminescence intensity.In this review article,photon energy harvesting and transferring mechanisms in Nd^3+,Yb^3+and emitter ions co-doped upconversion nanoparticles under 808 nm excitation are briefly discussed.Factors that affect upconversion luminescence intensity and quantum yield of Nd^3+-sensitized upconversion nanoparticles are also addressed.Besides,some of the important strategies that have been recently utilized to boost upconversion luminescence intensity of Nd^3+sensitized upco nversion nanoparticles are tho roughly summarized.Lastly,the future challenges in the area and our perspectives are in sight. | Solomon Tiruneh Dibaba Xiaoqian Ge Wei Ren Lining Sun | 2019 | Journal of Rare Earths2019，37，8： | 9 |
| 6 | Evaluation of the anti-diabetic properties of Mucuna pruriens seed extract显示文摘Objective:To explore the antidiabetic properties of Mucuna pruriens(M.pruriens).Methods: Diabetes was induced in Wistar rats by single intravenous injection of 120 mg/kg of alloxan monohydrate and different doses of the extract were administered to diabetic rats.The blood glucose level was determined using a glucometer and results were compared with normal and untreated diabetic rats.The acute toxicity was also determined in albino mice.Results:Results showed that the administration of 5,10,20,30,40,50,and 100 mg/kg of the crude ethanolic extract of M.pruriens seeds to alloxan-induced diabetic rats(plasma glucose > 450 mg/dL) resulted in 18.6%,24.9%,30.8%,41.4%,49.7%,53.1%and 55.4%reduction,respectively in blood glucose level of the diabetic rats after 8h of treatment while the administration of glibenclamide (5 mg/kg/day) resulted in 59.7%reduction.Chronic administration of the extract resulted in a significant dose dependent reduction in the blood glucose level(P<0.001).It also showed that the antidiabetic activity of M.pruriens seeds resides in the methanolic and ethanolic fractions of the extract.Acute toxicity studies indicated that the extract was relatively safe at low doses,although some adverse reactions were observed at higher doses(8-32 mg/kg body weight),no death was recorded.Furthermore,oral administration of M.pruriens seed extract also significandy reduced the weight loss associated with diabetes.Conclusions:The study clearly supports the traditional use of M.pruriens for the treatment of diabetes and indicates that the plant could be a good source of potent antidiabetic drug. | Stephen O Majekodunmi Ademola A Oyagbemi Solomon Umukoro Oluwatoyin A Odeku | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，8： | 8 |
| 7 | Recent upper gastrointestinal panendoscopy increases the risk of pyogenic liver abscess显示文摘AIM To investigate the association between a recent gastrointestinal(GI) endoscopy and the subsequent risk of pyogenic liver abscess(PLA).METHODS We designed a nested case control study. Using the Taiwan National Health Insurance Research Database, 2135 patients with a first diagnosis of PLA were identified from 1998 to 2011. Another 10675 patients without PLA matched by age and sex were selected as reference controls. We identified and compared the possible risk factors for PLA and GI endoscopies performed before the index date(when PLA was diagnosed) between the two cohorts. Multivariate analysis was conducted to examine the risk of PLA within the 90 d after the GI endoscopies.RESULTS Patients with a history of diabetes [adjusted odds ratio(a OR) = 4.92, 95%CI: 1.78-13.61], end-stage renal disease(a OR = 3.98, 95%CI: 1.45-10.91), biliary tract infection(a OR = 2.68, 95%CI: 2.11-3.40), liver cirrhosis(a OR = 2.19, 95%CI: 1.39-3.46), GI malignancies(a OR = 5.68, 95%CI: 4.23-7.64), appendicitis(a OR = 3.16, 95%CI: 2.27-4.41), diverticulitis(a OR = 1.64, 95%CI: 1.01-2.64), and recent endoscopic retrograde cholangiopancreatography(a OR = 27.04, 95%CI: 11.65-62.72) were significantly associated with an increased risk of PLA. After adjusting for the above risk factors and the frequency of outpatient department visits and abdominal ultrasounds during 90 d before the index date, an upper GI panendoscopy(a OR = 2.75, 95%CI: 2.05-3.69) but not a lower GI endoscopy(a OR = 1.07, 95%CI: 0.62-1.86) was significantly associated with PLA.CONCLUSION An upper GI panendoscopy performed before 90 d may increase the risk of PLA. | Ming-Jen Tsai Chin-Li Lu Ying C Huang Chung Hsien Liu Wan-Ting Huang Kai-Yuan Cheng Solomon Chih-Cheng Chen | 2017 | World Journal of Gastroenterology2017，23，16： | 8 |
| 8 | Gastrointestinal neuroendocrine peptides/amines in inflammatory bowel disease显示文摘Inflammatory bowel disease(IBD) is a chronic recurrent condition whose etiology is unknown,and it includes ulcerative colitis,Crohn's disease,and microscopic colitis. These three diseases differ in clinical manifestations,courses,and prognoses. IBD reduces the patients' quality of life and is an economic burden to both the patients and society. Interactions between the gastrointestinal(GI) neuroendocrine peptides/amines(NEPA) and the immune system are believed to play an important role in the pathophysiology of IBD. Moreover,the interaction between GI NEPA and intestinal microbiota appears to play also a pivotal role in the pathophysiology of IBD. This review summarizes the available data on GI NEPA in IBD,and speculates on their possible role in the pathophysiology and the potential use of this information when developing treatments. GI NEPA serotonin,the neuropeptide Y family,and substance P are proinflammatory,while the chromogranin/secretogranin family,vasoactive intestinal peptide,somatostatin,and ghrelin are antiinflammatory. Several innate and adaptive immune cells express these NEPA and/or have receptors to them. The GI NEPA are affected in patients with IBD and in animal models of human IBD. The GI NEPA are potentially useful for the diagnosis and follow-up of the activity of IBD,and are candidate targets for treatments of this disease. | Magdy El-Salhy Tefera Solomon Trygve Hausken Odd Helge Gilja Jan Gunnar Hatlebakk | 2017 | World Journal of Gastroenterology2017，23，28： | 8 |

| 11 | Assessment of genetic variation in tomato (Solanum lycopersicum L.) inbred lines using SSR molecular markers显示文摘A study was conducted to determine the genetic diversity of 39 determinate and indeterminate tomato inbred lines collected from China,Japan,S. Korea,and USA. Using 35 SSR polymorphic markers,a total of 150 alleles were found with moderate levels of diversity,and a high number of unique alleles existing in these tomato lines. The mean number of alleles per locus was 4.3 and the average poly-morphism information content (PIC) was 0.31. Unweighted Pair Group Method with Arithmetic Mean (UPGMA) clustering at genetic similarity value of 0.85 grouped the inbred lines into four groups,where one USA cultivar formed a separate and more distant cluster. The most similar inbred lines are from USA,both with determinate type,whereas the most different lines are from USA (Us-16) and Japan (Ja-2) with determinate and indeterminate growth habit,respectively. Clustering was consistent with the known information regarding geographical location and growth habit. The genetic distance information reported in this study might be used by breeders when planning future crosses among these inbred lines. | Solomon Benor Mengyu Zhang Zhoufei Wang Hongsheng Zhang | 2008 | Journal of Genetics and Genomics2008，35，6： | 7 |

| 13 | Effect of medicinal mushrooms on blood cells under conditions of diabetes mellitus显示文摘Diabetes mellitus(DM) is the third most common noninfectious disease leading to early disability and high mortality. Moreover, the number of patients is growing every year. The main symptom of DM is hyperglycemia. Increased levels of blood glucose activate polyol, hexosamine, and protein kinase metabolic pathways cause the intensification of non-enzymatic glycosylation and nitration of macromolecules. This, in turn, leads to the development of oxidative and nitrative stresses and secondary complications, such as different kinds of microand macroangiopathies. Metabolic disorders caused by insulin deficiency in diabetes significantly impede the functioning of a homeostasis system, which change the physical, biochemical, morphological, and functional properties of blood cells. As a result, the oxygen-transport function of red blood cells(RBCs), rheological properties of the blood, and functions of immunocompetent cells as well as the process of apoptosis are primarily affected. Modern pharmacotherapy focuses on the search for new preparations that aim to decrease blood glucose levels. Undesirable side effects and adverse reactions caused by synthetic medicines led to the search and investigation of new preparations of natural origin. Medicinal mushrooms play an important role among such new preparations. They are a source of a large number of high-and lowmolecular compounds with pronounced biological effects. Our investigations show pronounced hypoglycemic and anti-anemic action of submerged cultivated mycelium powder of medicinal mushrooms Agaricus brasiliensis(A. brasiliensis) and Ganoderma lucidum(G. lucidum) on streptozotocin-induced DM in rats. Also, we showed that mycelium powders have membrane protective properties as evidenced by the redistribution of RBC populations towards the growth of full functional cell numbers. Normalization of parameters of leukocyte formula and suppression of apoptosis of white blood cells in diabeticrats treated with A. brasiliensis and G. lucidum mycelia indicates pronounced positive effects of these strains of mushrooms. Thus, the use of medicinal mushrooms for treatment of DM and in prevention development of its secondary complications might be a new effective approach of this disease's cure. This article is aimed at summarizing and analyzing the literature data and basic achievements concerning DM type 1 treatment using medicinal mushrooms and showing the results obtained in our research. | Taras Vitak Borys Yurkiv Solomon Wasser Eviatar Nevo Natalia Sybirna | 2017 | World Journal of Diabetes2017，8，5： | 6 |
| 14 | Antibacterial activity of selected ethnomedicinal plants from South India显示文摘Objective:To screen the antimicrobial potential of three ethnomedicinal plants Chassalia curviflora Thw.(C.curviflora),Cyclea peltata Hook.F.& Thomson(C.peltata) and Euphorbia hirta L(E.hirta) used in folk medicines in Aarukani hills Kani tribe,Tamil Nadu,India against human bacterial pathogens.Methods:Antibacterial efficacy was performed by disc diffusion method against the pathogens viz.,Escherichia coli(E.coli)(ATCC 35218),Staphylococcus aureus (S.aureus)(ATCC 6538),Salmonella typhi(S.typhi)(MTCC 733),Proteus vulgaris(P.vulgaris), Proteus mirabilis(P.mirabilis) and Streptococcus pyogenes(S.pyogenes) and incubated for 24 h at 37°C.Results:The maximum degree of antibacterial activity was observed in C.peltata followed by C.curviflora.While E.hirta showed comparatively low degree of antibacterial activity.The methanolic extract of C.peltata showed the antibacterial activity against three pathogens viz.,S.pyogenes,P.vulgaris and E.coli with the inhibition zones 12 mm,10 mm and 9 mm,respectively,hexane extracts of C.peltata also showed the antibacterial activity against two selected pathogens viz.,P.vulgaris and P.mirabilis with 15 mm and 12 mm of inhibition zones.All the three different concentrations(025,0.50 & 0.75 mg/mL) of methanolic extract of C. peltata show the inhibitory effect on the three susceptible bacteria S.pyogenes,P.vulgaris and E. coli with the maximum inhibition in the highest concentration(0.75 mg/mL).The methanolic and hexane extracts of C.curviflora exhibited the antibacterial activity against only one bacterium each i.e.P.vulgaris and S.typhi with the maximum zone of inhibition 13 and 11 mm respectively. The methanolic and hexane extracts of E.hirta exhibited the antibacterial activity against only one bacterium Le.S.pyogenes with the maximum zone of inhibition 13 and 11 mm respectively. Conclusions:The present investigation revealed that the C.curviflora,C.peltata and E.hirta are potentially good source of antibacterial agents and demonstrates the importance of such plants in traditional medicines. | Rajendran Darling Anpin Raja Solomon Jeeva Juststella Wilfred Prakash Johnson Marimuthu Antonisamy Varaprasadham Irudayaraj | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，5： | 6 |
| 15 | Coinfection of hepatitis B and hepatitis C virus in HIV-infectedpatients in south India显示文摘AIM: To screen for the co-infection of hepatitis B (HBV) and hepatitis C virus (HCV) in human immunodeficiency virus (HIV) infected patients in southern India. METHODS: Five hundred consecutive HIV infected patients were screened for Hepatitis B Virus (HBsAg and HBV-DNA) and Hepatitis C virus (anti-HCV and HCV-RNA) using commercially available ELISA kits; HBsAg, HBeAg/ anti-HBe (Biorad laboratories, USA) and anti-HCV (Murex Diagnostics, UK). The HBV-DNA PCR was performed to detect the surface antigen region (pre S-S). HCV-RNA was detected by RT-PCR for the detection of the constant 5' putative non-coding region of HCV. RESULTS: HBV co-infection was detected in 45/500 (9%) patients and HCV co-infection in 11/500 (2.2%) subjects. Among the 45 co-infected patients only 40 patients could be studied, where the detection rates of HBe was 55% (22/40), antiHBe was 45% (18/40) and HBV-DNA was 56% (23/40). Among 11 HCV co-infected subjects, 6 (54.5%) were anti-HCV and HCV RNA positive, while 3 (27.2%) were positive for anti-HCV alone and 2 (18%) were positive for HCV RNA alone. CONCLUSION: Since the principal routes for HIV transmission are similar to that followed by the hepatotropic viruses, as a consequence, infections with HBV and HCV are expected in HIV infected patients. Therefore, it would be advisable to screen for these viruses in all the HIV infected individuals and their sexual partners at the earliest. | Shanmugam Saravanan Vijayakumar Velu Nagalingeswaran Kumarasamy Subhadra Nandakumar Kailapuri Gangatharan Murugavel Pachamuthu Balakrishnan Solomon Suniti Sadras Panchatcharam Thyagarajan | 2007 | World Journal of Gastroenterology2007，13，37： | 6 |

| 18 | 亚热带海湾表层沉积物对磷的吸附解析特征研究显示文摘磷在沉积物-水界面的吸附解析过程对水体富营养化具有重要影响,目前亚热带海湾沉积物对磷的吸附解析特征并不清楚,其自身的粒度组成和理化性质对沉积物磷吸附解析影响尚不明晰.本研究以3个主要入海河口区采集的表层沉积物为基础,通过吸附动力学和等温吸附试验,研究了不同粒径、pH和盐度等环境因子对磷吸附解析特征的影响规律.采用连续提取(SEDEX)法对沉积物吸附磷前后样品进行磷赋存形态分级,探讨沉积物对磷相应的吸附机制.结果表明:亚热带海湾入海河口区表层沉积物对磷的吸附动力学过程可用准二级动力学模型描述,等温吸附曲线符合Langmuir-交叉型模型.沉积物对磷的最大吸附量(Q_(m))范围为0.332~0.864 mg/g,沉积物磷的吸附/解吸平衡质量浓度(EPC_(0))在0.076~0.150 mg/L之间.粒径较小的沉积物具有较强的磷吸附能力,海水酸碱度和盐度有利于沉积物磷吸附,吸附后的沉积物中可交换态磷(Ex-P)和铁结合态磷(Fe-P)含量明显增加,沉积物对磷的吸附过程同时存在物理吸附和化学吸附,且以物理吸附为主.研究显示,亚热带海湾表层沉积物较高含量的黏土矿物和高分子量的有机质能够促进磷在沉积物上的吸附,海水酸碱度和盐度对该区域水体富营养化具有一定的缓冲效应,但沉积物物理吸附结合能力较弱,存在再次释放污染的风险,该区域内源磷污染应引起重视,这对于亚热带海湾水体富营养化污染防治具有重要意义. | 黄慧倩 胡浩鹏 杨斌 宁志铭 Solomon Felix Dan 李嘉玉 沈奇健 | 2023 | 环境科学研究2023，36，2： | 5 |
| 19 | Atrazine biodegradation efficiency, metabolite detection, and trzD gene expression by enrichment bacterial cultures from agricultural soil显示文摘Atrazine is a selective herbicide used in agricultural fields to control the emergence of broadleaf and grassy weeds. The persistence of this herbicide is influenced by the metabolic action of habituated native microorganisms. This study provides information on the occurrence of atrazine mineralizing bacterial strains with faster metabolizing ability. The enrichment cultures were tested for the biodegradation of atrazine by high-performance liquid chromatography(HPLC) and mass spectrometry. Nine cultures JS01.Deg01 to JS09.Deg01 were identified as the degrader of atrazine in the enrichment culture. The three isolates JS04.Deg01, JS07.Deg01, and JS08.Deg01 were identified as efficient atrazine metabolizers. Isolates JS04.Deg01 and JS07.Deg01 produced hydroxyatrazine(HA) N-isopropylammelide and cyanuric acid by dealkylation reaction. The isolate JS08.Deg01 generated deethylatrazine(DEA), deisopropylatrazine(DIA), and cyanuric acid by N-dealkylation in the upper degradation pathway and later it incorporated cyanuric acid in their biomass by the lower degradation pathway. The optimum pH for degrading atrazine by JS08.Deg01 was 7.0 and 16S rDNA phylogenetic typing identified it as Enterobacter cloacae strain JS08.Deg01. The highest atrazine mineralization was observed in case of isolate JS08.Deg01, where an ample amount of trzD mRNA was quantified at 72 h of incubation with atrazine. Atrazine bioremediating isolate E. cloacae strain JS08.Deg01 could be the better environmental remediator of agricultural soils and the crop fields contaminated with atrazine could be the source of the efficient biodegrading microbial strains for the environmental cleanup process. | Robinson David Jebakumar SOLOMON Amit KUMAR Velayudhan SATHEEJA SANTHI | 2013 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2013，14，12： | 5 |
| 20 | Phaeocystis globosa Bloom Monitoring: Based on P. globosa Induced Seawater Viscosity Modification Adjacent to a Nuclear Power Plant in Qinzhou Bay, China显示文摘The mucus produced by the outbreak of Phaeocystis globosa in the adjacent waters of the Fangchenggang Nuclear Power Plant(FCGNPP) in China has blocked the entrance of the cooling water filtration system of the FCGNPP, and posed a threat to the safe operation of the FCGNPP. At present, there is no related research on whether the changes in seawater viscosity could be used as a new method for monitoring and providing early warning of P. globosa tide. During a complete red tide cycle, the temporal and spatial changes in the hydrological conditions(temperature, salinity, dissolved oxygen), chlorophyll-a(Chl-a), composition and abundance of phytoplankton, number and size of P. globose colonies, concentration of transparent exopolymer particles(TEP) and the seawater viscosity were measured in this study. The results indicate that there was an extremely significant negative correlation between the physical seawater viscosity η_(T,S) and temperature, and the correlation coefficient reached-0.998. The biological seawater viscosity η_(Bio) was positively correlated with the number of P. globosa colonies, and the correlation coefficients is 0.747. Because the increase in phytoplankton abundance, especially during the outbreak of P. globosa and a large amount of mucus produced by the colonies could significantly increase seawater viscosity, we suggest that biological factors were the main reasons for the increase in seawater viscosity. The η_(Bio) was completely consistent with the occurrence process of P. globosa bloom and could be used as a valuable index for P. globosa bloom monitoring. | KANG Zhenjun YANG Bin LAI Junxiang NING Yi ZHONG Qiuping LU Dongliang LIAO Riquan WANG Pei Solomon Felix Dan SHE Zhicai JIA Zhen LAO Yanling LI Nan | 2020 | Journal of Ocean University of China2020，19，5： | 5 |
