1Two-Party Authenticated Key Agreement in Certificateless Public Key Cryptography显示文摘Certificateless public key cryptography was introduced to overcome the key escrow limitation of the identity-based cryp- tography. It combines the advantages of the identity-based cryp- tography and the traditional PKI. Many certificateless public key encryption and signature schemes have been proposed. However, the key agreement in CL-PKE is seldom discussed. In this paper, we present a new certificateless two party authentication key agreement protocol and prove its security attributes. Compared with the existing protocol, our protocol is more efficient.SHI Yijuan LI Jianhua 2007Wuhan University Journal of Natural Sciences2007,12,1:23
2Optimization of Agrobacterium tumefaciens-Mediated Transformation Systems in Tea Plant(Camellia sinensis)显示文摘In this study, an efficient plant regeneration protocol in vitro and transformation by Agrobacterium-mediated method of Camellia sinensis was achieved, which would lay the foundation for genetic improvement of tea plant by genetic engineering technology. The cotyledon callus of C.sinensis were used as the receptors for transformation by Agrobacterium tumefaciens EHA105 containing PS1aG-3. Some factors which affected the result of Agrobacterium-mediated transformation of C. sinensis were studied on the basis of GUS transient expression system. The optimum system of Agrobacterium-mediated transformation was that the cotyledon callus were pre-cultured for 3 d, and then infected by EHA105 for 15 min followed by 3 d co-culture in the dark on the YEB medium containing 150 μmol·L^(-1) acetosyringone(AS). The transient expression rate of GUS gene was 62.6%. After being delayed selective culture for 3 d, infected callus were transferred into the differentiation medium and the root induction medium both of which were supplemented with 100 mg·L^(-1) spectinomycin, and then resistant seedlings of C. sinensis were obtained. The conversion rate was 3.6%.LV Qianru CHEN Changsong XU Yijuan HU Shunkai WANG Le SUN Kang CHEN Xuan LI Xinghui 2017Horticultural Plant Journal2017,3,3:9
3Low-temperature selective catalytic reduction of NO_(x) with NH_(3) over zeolite catalysts:A review显示文摘The selective catalytic reduction(SCR)of NO_(x) by NH3 is one of the most mature technologies for NO_(x) treatment.Catalysts are the main factors affecting denitrification efficiency.Zeolites as low-tempe rature NH3-SCR catalysts have been extensively studied in the past few years.In this work,the mechanism of zeolites for NH3-SCR reaction was reviewed and the denitrification performances of zeolite catalysts prepared by different methods were compared.The effects of sulfur and water poisoning on zeolite catalysts in NH3-SCR reaction were also analyzed.Several ways to address the problems in lowtemperature NH3-SCR reaction were discussed.Hopefully,this review could provide a fundamental understanding of SCR reaction on zeolite catalysts and pave the way toward similar studies to realize its commercial applications.Yijuan Pu Xinyu Xie Wenju Jiang Lin Yang Xia Jiang Lu Yao 2020Chinese Chemical Letters2020,31,10:9
4Relationships of ozone formation sensitivity with precursors emissions,meteorology and land use types,in Guangdong-Hong Kong-Macao Greater Bay Area,China显示文摘Due to the influences of precursors emissions,meteorology,geography and other factors,ozone formation sensitivity(OFS)is generally spatially and temporally heterogeneous.This study characterized detailed spatial and temporal variations of OFS in Guangdong-Hong Kong-Macao Greater Bay Area(GBA)from 2012 to 2016 based on OMI satellite data,and analyzed the relationships of OFS with precursors emissions,meteorology and land use types(LUTs).From 2012 to 2016,the OFS tended to be NOx-limited in GBA,with the value of FNR(HCHO/NO 2)increasing from 2.04 to 2.22.According to the total annual emission statistics of precursors,NOx emissions decreased by 33.1%and VOCs emissions increased by 35.2%from 2012 to 2016,directly resulting in OFS tending to be NO x-limited.The Grey Relation Analysis results show that total column water(TCW),surface net solar radiation(SSR),air temperature at 2 m(T2)and surface pressure(SP)are the top four meteorological factors with the greatest influences on OFS.There are significant positive correlations between FNR and T2,SSR,TCW,and significant negative correlations between FNR and SP.In GBA,the OFS tends to be NO x-limited regime in wet season(higher T2,SSR,TCW and lower SP)and VOCs-limited regime in dry season(lower T2,SSR,TCW and higher SP).The FNR displays obvious gradient variations on different LUTs,with the highest in“Rural areas”,second in“Suburban areas”and lowest in“Urban areas”.Yuping Chen Hui Yan Yijuan Yao Chunling Zeng Ping Gao Liyue Zhuang Liya Fan Daiqi Ye 2020Journal of Environmental Sciences2020,32,8:5
5BK nephropathy in the native kidneys of patients with organ transplants: Clinical spectrum of BK infection显示文摘Nephropathy secondary to BK virus, a member of the Papoviridae family of viruses, has been recognized for some time as an important cause of allograft dysfunction in renal transplant recipients. In recent times, BK nephropathy(BKN) of the native kidneys has being increasingly recognized as a cause of chronic kidney disease in patients with solid organ transplants, bone marrow transplants and in patients with other clinical entities associated with immunosuppression. In such patients renal dysfunction is often attributed to other factors including nephrotoxicity of medications used to prevent rejection of the transplanted organs. Renal biopsy is required for the diagnosis of BKN. Quantitation of the BK viral load in blood and urine are surrogate diagnostic methods. The treatment of BKN is based on reduction of the immunosuppressive medications. Several compounds have shown antiviral activity, but have not consistently shown to have beneficial effects in BKN. In addition to BKN, BK viral infection can cause severe urinary bladder cystitis, ureteritis and urinary tract obstruction as well as manifestations in other organ systems including the central nervous system, the respiratory system, the gastrointestinal system and the hematopoietic system. BK viral infection has also been implicated in tumorigenesis. The spectrum of clinical manifestations from BK infection and infection from other members of the Papoviridae family is widening. Prevention and treatment of BK infection and infections from other Papovaviruses are subjects of intense research.Darlene Vigil Nikifor K Konstantinov Marc Barry Antonia M Harford Karen S Servilla Young Ho Kim Yijuan Sun Kavitha Ganta Antonios H Tzamaloukas 2016World Journal of Transplantation2016,6,3:4
6Hospital-Based Phenotypic Features and Treatment Outcomes of Chinese Women with Polycystic Ovary Syndrome: The Effect of Body Mass Index and Geographic Distribution显示文摘Genetic,lifestyle,and environmental factors contribute to the etiology of polycystic ovary syndrome(PCOS).Increased body mass index(BMI)exacerbates the reproductive and metabolic parameters and reduces the fecundity of women with PCOS.This is a secondary analysis of a large-sample,multicenter,randomized controlled trial conducted at 21 sites in Chinese mainland.A total of 1000 women diagnosed with PCOS were enrolled in this trial.Of these,998 women with PCOS were included in the analysis.Increased BMI was associated with more severe menstrual irregularities,elevated testosterone level,higher prevalence of metabolic syndrome,and poorer quality of life.The rates of ovulation per woman for the normal,overweight,and obese BMI groups were 83.0%,78.2%,and 63.6%,respectively(P<0.001),and the rates of live birth were 23.6%,18.1%,and 15.3%(P=0.030).Northern PCOS patients showed more severe reproductive,glucose,and lipid profiles;less exercise;and lower total ovulation rates compared with PCOS patients from Southern China(74.8%vs 81.2%,absolute difference 6.4%,95%confidence interval 1.2%–11.5%).The results show the typical phenotypic features of Han women with PCOS in Northern and Southern China.The women living in Northern China showed a higher BMI,more severe glycolipid metabolism profiles,and subsequently worse clinical outcomes by the same interventions than those living in Southern China.The difference in phenotypic features can be explained mostly by differences in BMI and the resulting difference in ovulation.Jingshu Gao Hongli Ma Yu Wang Xinming Yang Yijuan Cao Bei Zhang Conghui Han Xiaoke Wua 2021Engineering2021,7,2:3
7Nephropathy in dietary hyperoxaluria:A potentially preventable acute or chronic kidney disease显示文摘Hyperoxaluria can cause not only nephrolithiasis and nephrocalcinosis,but also renal parenchymal disease histologically characterized by deposition of calcium oxalate crystals throughout the renal parenchyma,profound tubular damage and interstitial inflammation and fibrosis.Hyperoxaluric nephropathy presents clinically as acute or chronic renal failure that may progress to endstage renal disease(ESRD).This sequence of events,well recognized in the past in primary and enteric hyperoxalurias,has also been documented in a few cases of dietary hyperoxaluria.Estimates of oxalate intake in patients with chronic dietary hyperoxaluria who developed chronic kidney disease or ESRD were comparable to the reported average oxalate content of the diets of certain populations worldwide,thus raising the question whether dietary hyperoxaluria is a primary cause of ESRD in these regions.Studies addressing this question have the potential of improving population health and should be undertaken,alongside ongoing studies which are yielding fresh insights into the mechanisms of intestinal absorption and renal excretion of oxalate,and into the mechanisms of development of oxalate-induced renal parenchymal disease.Novel preventive and therapeutic strategies for treating all types of hyperoxaluria are expected to develop from these studies.Robert H Glew Yijuan Sun Bruce L Horowitz Konstantin N Konstantinov Marc Barry Joanna R Fair Larry Massie Antonios H Tzamaloukas 2014World Journal of Nephrology2014,3,4:3

9Prolonged hypernatremia triggered by hyperglycemic hyperosmolar state with coma: A case report显示文摘A man with past lithium use for more than 15 years, but off lithium for two years and not carrying the diagnosis of diabetes mellitus or nephrogenic diabetes insipidus(NDI), presented with coma and hyperglycemic hyperosmolar state(HHS). Following correction of HHS, he developed persistent hypernatremia accompanied by large volumes of urine with low osmolality and no response to desmopressin injections. Urine osmolality remained < 300 m Osm/kg after injection of vasopressin. Improvement in serum sodium concentration followed the intake of large volumes of water plus administration of amiloride and hydrochlorothiazide. Severe hyperglycemia may trigger symptomatic lithium-induced NDI years after cessation of lithium therapy. Patients with newonset diabetes mellitus who had been on prolonged lithium therapy in the past require monitoring of their serum sodium concentration after hyperglycemic episodes regardless of whether they do or do not carry the diagnosis of NDI.Darlene Vigil Kavitha Ganta Yijuan Sun RichardⅠDorin Antonios H Tzamaloukas Karen S Servilla 2015World Journal of Nephrology2015,4,2:3

16Semen Analysis and Fecundity Association Among Women with Polycystic Ovary Syndrome Experiencing Ovulatory Dysfunction Treated by Ovulation Induction显示文摘In this study,normal values of semen analysis were set for a general infertile population of couples among which most women had normal ovulation.The predictive capacity values of sperm quality,including concentration,motile count,progressive motile count,and morphology,are unclear for women with polycystic ovary syndrome(PCOS).A secondary analysis was conducted based on a randomized controlled trial investigating infertility among women with PCOS experiencing ovulatory disorder between 2011 and 2016 in China.A total of 1000 women received ovulation induction(acupuncture and clomiphene).We randomized the women with PCOS in 27 hospitals in China who received one of four interventions(acupuncture plus clomiphene,sham acupuncture plus clomiphene,acupuncture plus placebo,or sham acupuncture plus placebo).Semen analysis was performed for every male partner according to the World Health Organization(WHO)criteria.The outcomes included conception,clinical pregnancy,and live birth.Logistic regression was used to evaluate the predictive value of semen analysis among ovulatory women for conception,clinical pregnancy,and live birth.Among the 1000 couples,the number of couples who attained ovulation,conception,clinical pregnancy,and live birth were 780,320,235,and 205,respectively.Semen volume and motility were applied and used as prediction parameters for conception(area under the curve(AUC)of 0.62(95%confidence interval(CI),0.55–0.69)),clinical pregnancy(AUC of 0.67(95%CI:0.61–0.73)),and live birth(AUC of 0.57(95%CI:0.50–0.64)).No poor calibration was shown for these models in Hosmer–Lemeshow tests.The predictive capacity of semen analysis for treatment outcome in PCOS women with PCOS experiencing with ovulatory dysfunction is limited.Jingshu Gao Yu Wang Mubai Li Mengyi Zhu Xuekui Liu Hongli Ma Yijuan Cao Lu Li Xinming Yang Xiaoke Wu 2021Engineering2021,7,11:1
