1Brazilian biosafety law and the new breeding technologies显示文摘Globally,the area of land cultivated with genetically modified(GM)crops has increased a thousand-fold over the last two decades.Although this technology has become important for food production,the regulatory frameworks that underpin these outcomes are based on a list of requirements for a risk assessment that differ from country to country.In recent years,policymakers have had the opportunity to learn from the controversies over transgenics to create effective regulatory milestones for emerging technologies,allowing them to reach their potential for a more sustainable agriculture,ensuring food security.In Brazil,Law No.11.105 of 24 March 2005 established a framework with four main organizations responsible for risk assessment and management.However,most of new breeding technologies did not exist at that time and were not considered in this law.In2016,Normative Resolution No.16 of the National Biosafety Technical Commission(CTNBio)was established to address this gap based on the evaluation of the products obtained through these techniques(termed Innovative Precision Improvement Techniques in the resolution),in a case-by-case consultation system.Briefly,if the product is designated to be a GM,the developer will have to go through the biosafety requirements and will be approved only after CTNBio risk assessment.If the product is designated not to be GM(for the purposes of the legislation),then it can be registered using the existing procedures.Currently,152 GM products are commercially approved in Brazil.In 2018,CTNBio assessed the first consultation on commercial release of plants generated using the new breeding technologies and has subsequently approved six products.It is expected that many institutions would be able to participate in Brazilian and world markets,developing and introducing new biotechnological solutions and products through a more sustainable approach and without facing public disapproval,a common issue for GM crops.Alexandre Lima NEPOMUCENO Renata FUGANTI-PAGLIARINI Maria Sueli Soares FELIPE Hugo Bruno Correa MOLINARI Edivaldo Domingues VELINI Eduardo Romano de Campos PINTO Maria Lucia Zaidan DAGLI Galdino ANDRADE FILHO Patricia Machado Bueno FERNANDES 2020Frontiers of Agricultural Science and Engineering2020,7,2:5
2巴西生物安全立法与转基因作物的应用显示文摘巴西目前有37个转基因品种获准商业化,转基因性状包括除草剂抗性、昆虫和病毒抗性。《巴西生物安全法》对科研及市场产品研发过程中如何安全运用遗传工程技术建立了指导准则,该法设立了新的机构并让高校与政府机构参与共同制定生物安全指导方针、进行风险评估和行政监督。根据该法,巴西设立了'国家生物安全理事会'(CNBS),并重组了'国家生物安全技术委员会'(CTNBio)。CTNBio负责建立生物安全指导准则,并向所有从事转基因生物相关机构颁发'生物安全许可证'(CQB)。《生物安全法》将所有违反其准则的行为或不作为均视为违法。在注册与监督机构(OERF)确定制裁标准、规定罚金数额并提交给联邦政府后,即可对违法行为实施制裁。除此之外,巴西有关转基因生物的重要法规还有第8078号法,该条款赋予国内所有消费者知情权。依据该法律,巴西司法部建立了食品标识体系,规定人体食用或饲料用食品或食品成分若含有超过1%的转基因生物成分,必须在商品标签上注明并附转基因标志(正中间含有字母T的黄色三角形)。不可否认,在这部新的《生物安全法》颁布实施后,遗传工程技术在巴西农业中的应用呈现快速增长。毫无疑问,在各机构的协作参与下,生物安全立法框架中的法律、规定和指导准则联合作用,让投资者、科研工作者、公私营机构及其他所有巴西农业的利益相关者重拾信心。Alexandre Lima Nepomuceno Mauricio Antonio Lopes Flavio Finardi-Filho Marcus Vinicius Segurado Coelho Renata Fuganti-Pagliarini 王虹 2014华中农业大学学报2014,33,6:4
3Embryonal rhabdomyosarcoma in the maxillary sinus with orbital involvement in a pediatric patient:Case report显示文摘This report presents a case of embryonal rhabdomyosarcoma(e RMS) located in the left maxillary sinus and invading the orbital cavity in a ten-year-old male patient who was treated at a referral hospital.The images provided from the computed tomography showed a heterogeneous mass with soft-tissue density,occupying part of the left half of the face inside the maxillary sinus,and infiltrating and destroying the bone structure of the maxillary sinus,left orbit,ethmoidal cells,nasal cavity,and sphenoid sinus.An analysis of the histological sections revealed an undifferentiated malignant neoplasm infiltrating the skeletal muscle tissue.The immunohistochemical analysis was positive for the antigens:MyoD 1,myogenin,desmin,and Ki67(100% positivity in neoplastic cells),allowing the identification of the tumour as an eR MS.The treatment protocol included initial chemotherapy followed by radiotherapy and finally surgery.The total time of the treatment was nine months,and in 18-mo of follow-up period did not show no local recurrences and a lack of visual impairment.Ana Carolina Rodrigues de Melo Tácio Candeia Lyra Isabella Lima Arrais Ribeiro Alexandre Rolim da Paz Paulo Rogério Ferreti Bonan Ricardo Dias de Castro Ana Maria Gondim Valen?a 2017World Journal of Clinical Cases2017,5,12:3
4Personalized medicine in gastric cancer:Where are we andwhere are we going?显示文摘Despite improvements in adjuvant therapies for gastric cancer in recent years, the disease is characterized by high recurrence rates and a dismal prognosis. The major improvement in the treatment of recurrent or metastatic gastric cancer in recent years has been the incorporation of trastuzumab, a monoclonal antibody that inhibits human epidermal growth factor receptor 2(HER2) heterodimerization, after the demonstrated predictive value of the overexpression and/or amplification of this receptor. Beyond HER2, other genetic abnormalities have been identified, and these mutations may be targetable by tyrosine kinase inhibitors or monoclonal antibodies. The demonstration of four distinct molecular subtypes of gastric cancer by the Cancer Genome Atlas study highlight the enormous heterogeneity of the disease and its complex interplay between genetic and epigenetic alterations and provide a roadmap to implement genome-guided personalized therapy in gastric cancer. In the present review, we aim to discuss, from a clinical point of view, the genomic landscape of gastric cancer described in recent studies, the therapeutic insights derived from these findings, and the clinical trials that have been conducted and those in progress that take into account tailored therapies for gastric cancer.Alexandre A Jácome Anelisa K Coutinho Enaldo M Lima Aline C Andrade JoséSebastião dos Santos 2016World Journal of Gastroenterology2016,22,3:2

9Challenges in the chemotherapy of Chagas disease: Looking for possibilities related to the differences and similarities between the parasite and host显示文摘Almost 110 years after the first studies by Dr. Carlos Chagas describing an infectious disease that was named for him, Chagas disease remains a neglected illness and a death sentence for infected people in poor countries. This short review highlights the enormous need for new studies aimed at the development of novel and more specific drugs to treat chagasic patients. The primary tool for facing this challenge is deep knowledge about the similarities and differences between the parasite and its human host.Vitor Sueth-Santiago Debora Decote-Ricardo Alexandre Morrot Celio Geraldo Freire-de-Lima Marco Edilson Freire Lima 2017World Journal of Biological Chemistry2017,8,1:1

12SARS-CoV-2 productively infects primary human immune system cells in vitro and in CoviD-19 patients显示文摘The severe acute respiratory syndrome coronavirus 2(SARS-CovV-2)infection is associated with a hyperinflammatory state and lymphocytopenia,a hallmark that appears as both signature and prognosis of disease severity outcome.Although cytokine storm and a sustained inflammatory state are commonly associated with immune cell depletion,it is still unclear whether direct SARS-Cov-2 infection of immune cells could also play a role in this scenario by harboring viral replication.We found that monocytes,as well as both B and T lymphocytes,were susceptible to SARS-Cov-2 infection in vitro,accumulating double-stranded RNA consistent with viral RNA replication and ultimately leading to expressive T cell apoptosis.In addition,flow cytometry and immunofluorescence analysis revealed that SARS-Cov-2 was frequently detected in monocytes and B lymphocytes from coronavirus disease 2019(CoVID-19)patients.The rates of SARS-Cov-2-infected monocytes in peripheral blood mononuclear cells from CoVID-19 patients increased over time from symptom onset,with SARS-CoV-2-positive monocytes,B cells,and CD4+T lymphocytes also detected in postmortem lung tissue.These results indicated that SARS-CoV-2 infection of blood-circulating leukocytes in covID-19 patients might have important implications for disease pathogenesis and progression,immune dysfunction,and virus spread within the host.Marjorie C.Pontelli italo A.Castro Ronaldo B.Martins Leonardo La Serra Flavio P.Veras Daniele C.Nascimento Camila M.Silva Ricardo S.Cardoso Roberta Rosales Rogério Gomes Thais M.Lima Juliano P.Souza Brenda C.Vitti Diego B.Caetite Mikhael H.F.de Lima Spencer D.Stumpf Cassandra E.Thompson Louis-Marie Bloyet Juliana E Toller-Kawahisa Marcela C.Giannini Leticia P.Bonjorno Marial.F.Lopes Sabrina S.Batah Li Siyuan Rodrigo Luppino-Assad Sergio C.L.Almeida Fabiola R.Oliveira Maira N.Benatti Lorena L.F.Pontes Rodrigo C.Santana Fernando C.Vilar Maria Auxiliadora-Martins Pei-Yong Shi Thiago M.Cunha Rodrigo T.Calado JoséC.Alves-Filho Dario S.Zamboni Alexandre T.Fabro Paulo Louzada-Junior Rene D.R.Oliveira Sean P.J.Whelan Fernando Q.Cunha Eurico Arruda 2022Journal of Molecular Cell Biology2022,14,4:1
13Bioactive extracts of red seaweeds Pterocladiella capillacea and Osmundaria obtusiloba(Floridophyceae:Rhodophyta) with antioxidant and bacterial agglutination potential显示文摘Objective:To evaluate the antioxidant,antibacterial and bacterial cell agglutination activities of the hexane(Hex) and 70%ethanol(70%EtOH) extracts of two species of red seaweeds Pterocladiella capillacea(P.capillacea) and Osmundaria obtusiloba.Methods:In vitro antioxidant activity was determined by DPPH radical scavenging assay,ferric-reducing antioxidant power assay,ferrous ion chelating assay,β-carotene bleaching assay and total phenolic content quantification.Antimicrobial activity was tested using the method of disc diffusion on Mueller-Hinton medium.The ability of algal extracts to agglutinate bacterial cells was also tested.Results:The 70%EtOH extract of the two algae showed the highest values of total phenolic content compared to the Hex extract.The results of DPPH for both extracts(Hex,70%EtOH) of Osmundaria obtusiloba(43.46%and 99.47%) were higher than those of P.capillacea(33.04%and 40.81%) at a concentration of 1 000 μg/mL.As for the ferrous ion chelating,there was an opposite behavior,extracts of P.capillacea had a higher activity.The extracts showed a low ferric-reducing antioxidant power,with optical density ranging from0.054 to 0.180.Antioxidant activities of all extracts evaluated for β-carotene bleaching were above 40%.There was no antibacterial activity against bacterial strains tested.However,the extracts of both species were able to agglutinate bacterial Gram positive cells of Staphylococcus aureus and Gram negative cells of Escherichia coli,multidrug-resistant Salmonella and Vibrio harveyi.Conclusions This is the first report of the interaction between these algal extracts,rich in natural compounds with antioxidant potential,and Gram positive and Gram negative bacterial cells.Daniel Barroso de Alencar Fátima Cristiane Teles de Carvalho Rosa Helena Rebouas Daniel Rodrigues dos Santos Kelma Maria dos Santos Pires-Cavalcante Rebeca Larangeira de Lima Bárbara Mendes Baracho Rayssa Mendes Bezerra Francisco Arnaldo Viana Regine Helena Silva dos Fernandes Vieira Alexandre Holanda Sampaio Oscarina Viana de Sousa Silvana Saker-Sampaio 2016Asian Pacific Journal of Tropical Medicine2016,9,4:1

15FungalTraits:a user-friendly traits database of fungi and fungus-like stramenopiles显示文摘The cryptic lifestyle of most fungi necessitates molecular identification of the guild in environmental studies.Over the past decades,rapid development and affordability of molecular tools have tremendously improved insights of the fungal diversity in all ecosystems and habitats.Yet,in spite of the progress of molecular methods,knowledge about functional properties of the fungal taxa is vague and interpretation of environmental studies in an ecologically meaningful manner remains challenging.In order to facilitate functional assignments and ecological interpretation of environmental studies we introduce a user friendly traits and character database FungalTraits operating at genus and species hypothesis levels.Combining the information from previous efforts such as FUNGuild and FunFun together with involvement of expert knowledge,we reannotated 10,210 and 151 fungal and Stramenopila genera,respectively.This resulted in a stand-alone spreadsheet dataset covering 17 lifestyle related traits of fungal and Stramenopila genera,designed for rapid functional assignments of environmental stud-ies.In order to assign the trait states to fungal species hypotheses,the scientific community of experts manually categorised and assigned available trait information to 697,413 fungal ITS sequences.On the basis of those sequences we were able to summarise trait and host information into 92,623 fungal species hypotheses at 1%dissimilarity threshold.Sergei Põlme Kessy Abarenkov RHenrik Nilsson Björn D.Lindahl Karina Engelbrecht Clemmensen Havard Kauserud Nhu Nguyen Rasmus Kjøller Scott T.Bates Petr Baldrian Tobias Guldberg Frøslev Kristjan Adojaan Alfredo Vizzini Ave Suija Donald Pfister Hans-Otto Baral Helle Järv Hugo Madrid Jenni Nordén Jian-Kui Liu Julia Pawlowska Kadri Põldmaa Kadri Pärtel Kadri Runnel Karen Hansen Karl-Henrik Larsson Kevin David Hyde Marcelo Sandoval-Denis Matthew E.Smith Merje Toome-Heller Nalin N.Wijayawardene Nelson Menolli Jr Nicole K.Reynolds Rein Drenkhan Sajeewa S.N.Maharachchikumbura Tatiana B.Gibertoni Thomas Læssøe William Davis Yuri Tokarev Adriana Corrales Adriene Mayra Soares Ahto Agan Alexandre Reis Machado Andrés Argüelles-Moyao Andrew Detheridge Angelina de Meiras-Ottoni Annemieke Verbeken Arun Kumar Dutta Bao-Kai Cui C.K.Pradeep César Marín Daniel Stanton Daniyal Gohar Dhanushka N.Wanasinghe Eveli Otsing Farzad Aslani Gareth W.Griffith Thorsten H.Lumbsch Hans-Peter Grossart Hossein Masigol Ina Timling Inga Hiiesalu Jane Oja John Y.Kupagme József Geml Julieta Alvarez-Manjarrez Kai Ilves Kaire Loit Kalev Adamson Kazuhide Nara Kati Küngas Keilor Rojas-Jimenez Krišs Bitenieks Laszlo Irinyi LászlóGNagy Liina Soonvald Li-Wei Zhou Lysett Wagner M.Catherine Aime MaarjaÖpik María Isabel Mujica Martin Metsoja Martin Ryberg Martti Vasar Masao Murata Matthew PNelsen Michelle Cleary Milan C.Samarakoon Mingkwan Doilom Mohammad Bahram Niloufar Hagh-Doust Olesya Dulya Peter Johnston Petr Kohout Qian Chen Qing Tian Rajasree Nandi Rasekh Amiri Rekhani Hansika Perera Renata dos Santos Chikowski Renato L.Mendes-Alvarenga Roberto Garibay-Orijel Robin Gielen Rungtiwa Phookamsak Ruvishika S.Jayawardena Saleh Rahimlou Samantha C.Karunarathna Saowaluck Tibpromma Shawn P.Brown Siim-Kaarel Sepp Sunil Mundra Zhu-Hua Luo Tanay Bose Tanel Vahter Tarquin Netherway Teng Yang Tom May Torda Varga Wei Li Victor Rafael Matos Coimbra Virton Rodrigo Targino de Oliveira Vitor Xavier de Lima Vladimir S.Mikryukov Yongzhong Lu Yosuke Matsuda Yumiko Miyamoto Urmas Kõljalg Leho Tedersoo 2020Fungal Diversity2020,,6:1

18Multi-generational SIR modeling: Determination of parameters, epidemiological forecasting and age-dependent vaccination policies显示文摘We use an age-dependent SIR system of equations to model the evolution of the COVID-19.Parameters that measure the amount of interaction in different locations(home,work,school,other)are approximated from in-sample data using a random optimization scheme,and indicate changes in social distancing along the course of the pandemic.That allows the estimation of the time evolution of classical and age-dependent reproduction numbers.With those parameters we predict the disease dynamics,and compare our results with out-of-sample data from the City of Rio de Janeiro.Finally,we provide a numerical investigation regarding age-based vaccination policies,shedding some light on whether is preferable to vaccinate those at most risk(the elderly)or those who spread the disease the most(the youngest).There is no clear upshot,as the results depend on the age of those immunized,contagious parameters,vaccination schedules and efficiency.Eduardo Lima Campos Rubens Penha Cysne Alexandre L.Madureira Gelcio L.Q.Mendes 2021Infectious Disease Modelling2021,6,1:1
