| 1 | Molecular genetics and genomics of the Rosoideae: state of theart and future perspectives显示文摘The Rosoideae is a subfamily of the Rosaceae that contains a number of species of economic importance,including the soft fruit species strawberry(Fragaria 3ananassa),red(Rubus idaeus)and black(Rubus occidentalis)raspberries,blackberries(Rubus spp.)and one of the most economically important cut flower genera,the roses(Rosa spp.).Molecular genetics and genomics resources for the Rosoideae have developed rapidly over the past two decades,beginning with the development and application of a number of molecular marker types including restriction fragment length polymorphisms,amplified fragment length polymorphisms and microsatellites,and culminating in the recent publication of the genome sequence of the woodland strawberry,Fragaria vesca,and the development of high throughput single nucleotide polymorphism(SNP)-genotyping resources for Fragaria,Rosa and Rubus.These tools have been used to identify genes and other functional elements that control traits of economic importance,to study the evolution of plant genome structure within the subfamily,and are beginning to facilitate genomic-assisted breeding through the development and deployment of markers linked to traits such as aspects of fruit quality,disease resistance and the timing of flowering.In this review,we report on the developments that have been made over the last 20 years in the field of molecular genetics and structural genomics within the Rosoideae,comment on how the knowledge gained will improve the efficiency of cultivar development and discuss how these advances will enhance our understanding of the biological processes determining agronomically important traits in all Rosoideae species. | Sara Longhi Lara Giongo Matteo Buti Nada Surbanovski Roberto Viola Riccardo Velasco Judson AWard Daniel J Sargent | 2014 | Horticulture Research2014,1,1: | 7 |
| 2 | CIMMYT小麦puroindoline基因型的进一步鉴定与分析显示文摘目的籽粒硬度是小麦市场分级和定价的重要依据,影响磨粉和食品加工品质。CIMMYT是我国最重要小麦引种地之一,研究其硬度基因型对我国小麦引种具有重要的应用价值。方法以CIMMYT常用的236份小麦亲本和高代品系为材料,采用改进的颗粒指数法、特异引物的PCR扩增和改进的SDS-PAGE凝胶电泳对其SKCS硬度及其puroindoine基因型进行鉴定和分析。结果202份硬质麦中,165份为PINA蛋白缺失类型;37份为Pinb-D1b类型,其中19份为非CIMMYT材料,18份亲本中均含有非CIMMYT材料。在34份软质麦中,有野生型、Pina-D1a/Pinb-D1i、Pina-D1c/Pinb-D1h、Pina-D1j/Pinb-D1i和Pina-D1a/Pinb-D1j共5种基因型。两种硬质类型中,Pina-D1b类型胚乳硬质程度明显高于(PSI硬度显著低于)Pinb-D1b类型;4种软质类型中,Pina-D1c/Pinb-D1h和Pina-D1a/Pinb-D1i类型胚乳硬质程度显著高于(PSI硬度显著低于)Pina-D1j/Pinb-D1i和Pina-D1a/Pinb-D1a类型。通过分析各类型的puroindoline基因序列发现,Pinb-D1h和Pinb-D1i编码同一种氨基酸,突变后仍表现为软质是因为第28位精氨酸变成色氨酸,其余软质变异类型色氨酸丰富区附近均未发生变化,这可能是导致其胚乳质地仍未变硬的主要原因。结论在先前研究基础上,本试验对CIMMYT小麦基因型作了进一步分析,发现系谱中没有外源材料的所有CIMMYT硬质麦均为Pina-D1b类型。从山羊草引进的软质突变类型之间存在一定硬度差异。 | 陈锋 夏先春 Manila William Morten Lillemo Richard Trethowan Roberto J Peňa 何中虎 | 2006 | 中国农业科学2006,39,8: | 6 |
| 3 | International NeuroAIDS: prospects of HIV-1 associated neurological com-plications显示文摘Neurological complications associated with HIV-1/AIDS are being recognized with a high frequency that parallels the increased number of AIDS cases. The early infiltration by HIV-1 into the nervous system can cause primary and/or secondary neurological complications. The most common neurocognitive disorder is AIDS Dementia Complex (ADC). In developing countries of Asia the three most opportunistic infections are tuberculosis (TB), cryptococcosis, and Pneumocystis carinii pneumonia. Therefore, it is expected that secondary neurological complications due to TB and cryptococcosis will be the most common cause of morbility and mortality in HIV-1/AIDS cases in China. Research of NeuroAIDS in China is necessary to understand the impact and the biology of HIV-1 in the nervous system. Future studies would include, the molecular epidemiology and the description of opportunistic infections associated to HIV-1; the neuropathological description of primary and secondary HIV-1 complications in different groups; the HIV-1 neurot- ropism and immune response studies for China’s unique HIV-1 strains and recombinant forms derived from the nervous system, including experimental models such as the use of transgenic rats; and the study of potential resistant virus, primarily when the anti-retroviral therapy (ART) has not full access in the brain. | J Roberto TRUJILLO Gilberto JARAMILLO-RANGEL Marta ORTEGA-MARTINEZ Augusto C PENALVA de OLIVEIRA Jose E VIDAL Joseph BRYANT Robert C GALLO | 2005 | Cell Research2005,15,11: | 4 |
| 4 | Management of hepatitis C in patients with chronic kidney disease显示文摘Hepatitis C virus(HCV) infection is highly prevalent among chronic kidney disease(CKD) subjects under hemodialysis and in kidney transplantation(KT) recipients, being an important cause of morbidity and mortality in these patients. The vast majority of HCV chronic infections in the hemodialysis setting are currently attributable to nosocomial transmission. Acute and chronic hepatitis C exhibits distinct clinical and laboratorial features, which can impact on managementand treatment decisions. In hemodialysis subjects, acute infections are usually asymptomatic and anicteric; since spontaneous viral clearance is very uncommon in this context, acute infections should be treated as soon as possible. In KT recipients, the occurrence of acute hepatitis C can have a more severe course, with a rapid progression of liver fibrosis. In these patients, it is recommended to use pegylated interferon(PEG-IFN) in combination with ribavirin, with doses adjusted according to estimated glomerular filtration rate. There is no evidence suggesting that chronic hepatitis C exhibits a more aggressive course in CKD subjects under conservative management. In these subjects, indication of treatment with PEG-IFN plus ribavirin relies on the CKD stage, rate of progression of renal dysfunction and the possibility of a preemptive transplant. HCV infection has been associated with both liver disease-related deaths and cardiovascular mortality in hemodialysis patients. Among those individuals, low HCV viral loads and the phenomenon of intermittent HCV viremia are often observed, and sequential HCV RNA monitoring is needed. Despite the poor tolerability and suboptimal efficacy of antiviral therapy in CKD patients, many patients can achieve sustained virological response, which improve patient and graft outcomes. Hepatitis C eradication before KT theoretically improves survival and reduces the occurrence of chronic graft nephropathy, de novo glomerulonephritis and post-transplant diabetes mellitus. | Roberto J Carvalho-Filho Ana Cristina CA Feldner Antonio Eduardo B Silva Maria Lucia G Ferraz | 2015 | World Journal of Gastroenterology2015,21,2: | 4 |
| 5 | Celiac disease serology in patients with different pretest probabilities: Is biopsy avoidable?显示文摘AIM: To establish the diagnostic performance of sev-eral serological tests, individually and in combination, for diagnosing celiac disease (CD) in patients with different pretest probabilities, and to explore potential se- rological algorithms to reduce the necessity for biopsy. METHODS: We prospectively performed duodenal biopsy and serology in 679 adults who had either high risk (n = 161) or low risk (n = 518) for CD. Blood samples were tested using six assays (enzyme-linked immunosorbent assay) that detected antibodies to tissue transglutaminase (tTG) and deamidated gliadin peptide (DGP). RESULTS: CD prevalence was 39.1% in the high-risk population and 3.3% in the low-risk group. In high-risk patients, all individual assays had a high diagnostic efficacy [area under receiving operator characteristic curves (AU ROC): 0.968 to 0.999]. In contrast, assays had a lower diagnostic efficacy (AU ROC: 0.835 to 0.972) in the low-risk group. Using assay combinations, it would be possible to reach or rule out diagnosis of CD without biopsy in 92% of cases in both pretest populations. We observed that the new DGP/tTG Screen assay resulted in a surplus compared to more conventional assays in any clinical situation. CONCLUSION: The DGP/tTG Screen assay could be considered as the best initial test for CD. Combinations of two tests, including a DGP/tTG Screen, might be able to diagnose CD accurately in different clinical scenarios making biopsy avoidable in a high proportion of subjects. | Emilia Sugai María L Moreno Hui J Hwang Ana Cabanne Adriana Crivelli Fabio Nach-man Horacio Vázquez Sonia Niveloni Julio Argonz Roberto Mazure Graciela La Motta María E Caniggia Edgardo Smecuol Néstor Chopita Juan C Gómez Eduardo Maurińo Julio C Bai | 2010 | World Journal of Gastroenterology2010,16,25: | 4 |
| 6 | Hepatitis C: Treatment of difficult to treat patients显示文摘Over the past several years, more so recently, treatment options for hepatitis C virus(HCV) have seemed to exponentially grow. Up until recently, the regimen of pegylated interferon(peg-IFN) and ribavirin(RBV) stood as the standard of care. Direct acting antivirals, which target nonstructural proteins involved in replication and infection of HCV were first approved in 2011 as an addition to the peg-IFN and RBV regimen and with them have come increased sustained virological response rates(SVR). The previously reported 50%-70% SVR rates using the combination of peg-IFN and RBV are no longer the standard of care with direct acting antiviral(DAA) based regimens now achieving SVR of 70%-90%. PegIFN free as well as 'all oral' regimens are also available. The current randomized controlled trials available show favorable SVRs in patients who are naive to treatment, non-cirrhotic, and not human immunodeficiency virus(HIV)-co-infected. What about patients who do not fit into these categories? In this review, we aim to discuss the currently approved and soon to be approved DAAs while focusing on their roles in patients that are treatment experienced, cirrhotic, or co-infected with HIV. In this discussion, review of the clinical trials leading to recent consensus guidelines as well as discussion of barriers to treatment will occur. A case will attempt will be made that social services, including financial support and drug/alcohol treatment, should be provided to all HCV infected patients to improve chances of cure and thus prevention of late stage sequela. | Eric G Hilgenfeldt Alex Schlachterman Roberto J Firpi | 2015 | World Journal of Hepatology2015,7,15: | 3 |
| 7 | Hepatitis C cirrhosis: New perspectives for diagnosis and treatment显示文摘Chronic hepatitis C infection is the leading cause of chronic liver disease, cirrhosis, hepatocellular carcinoma as well as the primary indication for liver transplantation in the United States. Despite recent advances in drugs for the treatment of hepatitis C, predictive models estimate the incidence of cirrhosis due to hepatitis C infection will to continue to rise for the next two decades. There is currently an immense interest in the treatment of patients with fibrosis and early-stage cirrhosis as treatment can lead to decrease in the rates of decompensated cirrhosis, hepatocellular carcinoma and need for liver transplantation in these patients. The goal of this paper is to provide clinicians and health care professionals further information about the treatment of patients with hepatitis C infection and cirrhosis. Additionally, the paper focuses on the disease burden, epidemiology, diagnosis and the disease course from infection to treatment. We provide an overview of multiple studies for the treatment of chronic hepatitis C infection that have included patients with cirrhosis. We also discuss the advantages and disadvantages of treatment in cirrhotic patients and focus on the most up to date guidelines available for treatment. | Vikas Khullar Roberto J Firpi | 2015 | World Journal of Hepatology2015,7,14: | 3 |
| 8 | Central nervous system vasculitis and polyneuropathy as first manifestations of hepatitis C显示文摘Sensory or motor peripheral neuropathy may be observed in a significant proportion of hepatitis C virus (HCV)-infected patients.However,central nervous system (CNS) involvement is uncommon,especially in cryoglobulin-negative subjects.We describe a case of peripheral neuropathy combined with an ischemic CNS event as primary manifestations of chronic HCV infection without cryoglobulinemia.Significant improvement was observed after antiviral therapy.We discuss the spectrum of neurological manifestations of HCV infection and review the literature. | Roberto J Carvalho-Filho Janaína Luz Narciso-Schiavon Luciano HL Tolentino Leonardo L Schiavon Maria Lucia G Ferraz Antonio Eduardo B Silva | 2012 | World Journal of Gastroenterology2012,18,2: | 3 |
| 9 | Integrated sources of photon quantum states based on nonlinear optics显示文摘The ability to generate complex optical photon states involving entanglement between multiple optical modes is not only critical to advancing our understanding of quantum mechanics but will play a key role in generating many applications in quantum technologies.These include quantum communications,computation,imaging,microscopy and many other novel technologies that are constantly being proposed.However,approaches to generating parallel multiple,customisable bi-and multi-entangled quantum bits(qubits)on a chip are still in the early stages of development.Here,we review recent advances in the realisation of integrated sources of photonic quantum states,focusing on approaches based on nonlinear optics that are compatible with contemporary optical fibre telecommunications and quantum memory platforms as well as with chip-scale semiconductor technology.These new and exciting platforms hold the promise of compact,low-cost,scalable and practical implementations of sources for the generation and manipulation of complex quantum optical states on a chip,which will play a major role in bringing quantum technologies out of the laboratory and into the real world. | Lucia Caspani Chunle Xiong Benjamin J Eggleton Daniele Bajoni Marco Liscidini Matteo Galli Roberto Morandotti David J Moss | 2017 | Light(Science & Applications)2017,6,1: | 3 |
| 10 | Quality of life, work productivity impairment and healthcare resources in inflammatory bowel diseases in Brazil显示文摘BACKGROUND Inflammatory bowel diseases(IBD)have been associated with a low quality of life(QoL)and a negative impact on work productivity compared to the general population.Information about disease control,patient-reported outcomes(PROs),treatment patterns and use of healthcare resources is relevant to optimizing IBD management.AIM To describe QoL and work productivity and activity impairment(WPAI),treatment patterns and use of healthcare resources among IBD patients in Brazil.METHODS A multicenter cross-sectional study included adult outpatients who were previously diagnosed with moderate to severe Crohn’s disease(CD)or ulcerative colitis(UC).At enrolment,active CD and UC were defined as having a Harvey Bradshaw Index≥8 or a CD Activity Index≥220 or calprotectin>200μg/g or previous colonoscopy results suggestive of inadequate control(per investigator criteria)and a 9-point partial Mayo score≥5,respectively.The PRO assessment included the QoL questionnaires SF-36 and EQ-5D-5L,the Inflammatory Bowel Disease Questionnaire(IBDQ),and the WPAI questionnaire.Information about healthcare resources and treatment during the previous 3 years was collected from medical records.Chi-square,Fisher’s exact and Student’s t-/Mann-Whitney U tests were used to compare PROs,treatment patterns and the use of healthcare resources by disease activity(α=0.05).RESULTS Of the 407 patients in this study(CD/UC:64.9%/35.1%,mean age 42.9/45.9 years,54.2%/56.6%female,38.3%/37.1%employed),44.7%/25.2%presented moderate-to-severe CD/UC activity,respectively,at baseline.Expressed in median values for CD/UC,respectively,the SF-36 physical component was 46.6/44.7 and the mental component was 45.2/44.2,the EQ-visual analog scale score was 80.0/70.0,and the IBDQ overall score was 164.0/165.0.Moderate to severe activity,female gender,being unemployed,a lower educational level and lower income were associated with lower QoL(P<0.05).Median work productivity impairment was 20%and 5%for CD and UC patients,respectively,and activity impairment was 30%,the latter being higher among patients with moderate to severe disease activity compared to patients with mild or no disease activity(75.0%vs 10.0%,P<0.001).For CD/UC patients,respectively,25.4%/2.8%had at least one surgery,38.3%/19.6%were hospitalized,and 70.7%/77.6%changed IBD treatment at least once during the last 3 years.The most common treatments at baseline were biologics(75.3%)and immunosuppressants(70.9%)for CD patients and 5-ASA compounds(77.5%)for UC patients.CONCLUSION Moderate to severe IBD activity,especially among CD patients,is associated with a substantial impact on QoL,work productivity impairment and an increased number of IBD surgeries and hospitalizations in Brazil. | Rogerio Serafim Parra Julio MF Chebli Heda MBS Amarante Cristina Flores Jose ML Parente Odery Ramos Milene Fernandes Jose JR Rocha Marley R Feitosa Omar Feres Antonio S Scotton Rodrigo B Nones Murilo M Lima Cyrla Zaltman Carolina D Goncalves Isabella M Guimaraes Genoile O Santana Ligia Y Sassaki Rogerio S Hossne Mauro Bafutto Roberto LK Junior Mikaell AG Faria Sender J Miszputen Tarcia NF Gomes Wilson R Catapani Anderson A Faria Stella CS Souza Rosana F Caratin Juliana T Senra Maria LA Ferrari | 2019 | World Journal of Gastroenterology2019,25,38: | 2 |
| 11 | Listeria monocytogenes following orthotopic liver transplantation:Central nervous system involvement and review of the literature显示文摘Listeria monocytogene is a well-recognized cause of bacteremia in immunocompromised individuals,including solid organ transplant recipients,but has been rarely reported following orthotopic liver transplantation. We describe a case of listeria meningitis that occurred within a week after liver transplantation. The patient developed a severe headache that mimicked tacrolimus encephalopathy,and was subsequently diagnosed with listeria meningitis by cerebrospinal fluid culture. The infection was successfully treated with three-week course of intravenous ampicillin. Recurrent hepatitis C followed and was successfully treated with interferon alfa and ribavirin. Fourteen cases of listeriosis after orthotopic liver transplantation have been reported in the English literature. Most reported cases were successfully treated with intravenous ampicillin. There were four cases of listeria meningitis,and the mortality of them was 50%. Early detection and treatment of listeria meningitis are the key to obtaining a better prognosis. | Shugo Mizuno Ivan R Zendejas Alan I Reed Robin D Kim Richard J Howard Alan W Hemming Denise C Schain Consuelo Soldevila-Pico Roberto J Firpi Shiro Fujita | 2007 | World Journal of Gastroenterology2007,13,32: | 2 |
| 12 | Interchangeability of corneal curvature and asphericity measurements provided by three different devices显示文摘AIM: To evaluate the interchangeability of keratometric and asphericity measurements provided by three measurement systems based on different optical principles.METHODS: A total of 40 eyes of 40 patients with a mean age of 34.1 y were included. In all cases, a corneal curvature analysis was performed with IOL-Master(IOLM), iDesign 2(ID2), and Sirius systems(SIR). Differences between instruments for flattest(K1) and steepest(K2) keratometric readings, as well as for magnitude and axis of corneal astigmatism were analyzed. Likewise, differences in asphericity(Q) between SIR and ID2 were also evaluated. RESULTS: Mean differences between devices for K1 were 0.20±0.21(P<0.001),-0.12±0.36(P=0.046) and-0.32±0.36 D(P<0.001) for the comparisons IOLM-SIR, IOLM-ID2 and SIR-ID2, respectively. The ranges of agreement for these comparisons between instruments were 0.41, 0.70, and 0.70 D. For K2, mean differences were 0.31±0.33(P<0.001),-0.08±0.43(P=0.265) and-0.39±0.38 D(P<0.001), with ranges of agreement of 0.65, 0.84, and 0.74 D. Concerning magnitude of astigmatism, ranges of agreement were in the limit of clinical relevance(0.49 D, P=0.011; 0.55 D, P=0.386; 0.43 D, P=0.05). In contrast, ranges of agreement were clinically relevant for astigmatic axis(26.68o, 33.83o and 18.37o, P≥0.121) and for Q between SIR and ID2(0.16, P<0.001). CONCLUSION: The keratometric corneal power, astigmatic axis and asphericity measurements provideby the three systems evaluated cannot be considered as interchangeable, whereas measurements of corneal astigmatism obtained with SIR and ID2 can be considered as interchangeable for clinical purposes. | David P.Pinero Roberto Soto-Negro Pedro Ruiz-Fortes Rafael J Pérez-Cambrodí Hideki Fukumitsu | 2019 | International Journal of Ophthalmology(English edition)2019,12,3: | 2 |
