Uphando lweGMO
Ubungqina obucacileyo: I-Glyphosate iye yaba yeyona isetyenziswa kakhulu emhlabeni, ngenxa yokwamkelwa ngokubanzi kwezityalo ezikwazi ukumelana ne-transgenic glyphosate emva kokwaziswa kwayo ngo-1996. I-Glyphosate inokusetyenziswa iyodwa, kodwa iqhele ukusetyenziswa njengesithako esisebenzayo se-Roundup. ®. Esi sibulali zinambuzane sinezinto ezininzi ezincedisayo, ezinokukhuthaza into engaziwayo ...
Ubungqina obucacileyo: Umchiza wokutshabalalisa ukhula i-Quizalofop-P-ethyl (QpE) uneziphumo eziyityhefu entlanzini, kodwa ulwazi olunqongopheleyo lukhoyo ngoku kwiziphumo zalo kwinkqubo ye-endocrine. Kuphononongo lwangoku, i-zebrafish yabantu abadala (i-Danio rerio) ibonakaliswe kwiindawo ezahlukeneyo (0, 2, 20, 200 μg / L) ye-QpE kwiintsuku ze-30. Kumadoda, ukuvezwa kwe-QpE kwandisa kakhulu i-plasma estradiol (E2) ...
I-Abstract: Kolu phononongo, kuphandwe ukuba iziphumo ze-glyphosate, eyi-herbicide ngaphakathi kwe-organophosphate kwaye engakhethiyo isetyenziswa kakhulu kwezolimo kumsebenzi we-enzyme ye-carbonic anhydrase, ukuveliswa kweentlobo ze-oxygen esebenzayo, i-apoptosis yeseli kunye ne-morphology yomzimba ngexesha lophuhliso lwe-embryonic. yezebrafish. Ukuza kuthi ga ngoku, iye yaphathwa i-embryo…
I-Abstract: Ukusetyenziswa kwee-toxins ezivela kwi-Bacillus thuringiensis njenge-biopesticides kulawulo lwebhayoloji yezinambuzane nakwizityalo eziguquguqukayo kwandisa ukufumaneka kwazo kwimo engqongileyo. Uvandlakanyo lwe-Ecotoxicological yee-delta-endotoxins ezine zikhala 1Aa, khala 1Ab, khala 1Ac, kwaye khala 2A ukusuka ku-B. thuringiensis zenziwa kwi-zebrafish uDanio rerio ukuphonononga okubi ...
Amagqabantshintshi: Imichiza yokutshabalalisa ukhula esekelwe kwi-Glyphosate (GBH) njenge-Roundup® isetyenziswa kakhulu kwezolimo nakwimimandla yasezidolophini nasezilalini njengomthi wokutshabalalisa ukhula. Indlela yokusebenza kwayo yayicatshangelwa ukuba yeyodwa kuphela kwizityalo kwaye ngaloo ndlela ithathwa njengekhuselekile kwaye ayinayo ityhefu. Nangona kunjalo, ubungqina obukhulayo bucebisa ukuba ii-GBHs zinokungakhuseleki njenge…
I-Glyphosate sisichiza sokhula esinenkqubo, esingakhethiyo esisetyenziswa kakhulu kwezolimo kwihlabathi jikelele. Isebenza njenge-inhibitor ye-enzyme ye-5-enolpyruvylshikimate-3-phosphate synthase ngokuphazamisa ukuhlanganiswa kwee-amino acids ezinuka kamnandi. Le ndlela ayikho kwizilwanyana, nangona ezinye izifundo zibonise ukuba i-glyphosate ye-herbicide inokuchaphazela ukuveliswa kweentlanzi. Kolu phononongo, i…
Abstract: Uphononongo lwangoku lujolise ekuqinisekiseni i-cytotoxicity yezibulali-zinambuzane ezidla ngokusetyenziswa ekulinyweni kwerayisi, ngovavanyo lwe-in vitro olusebenzisa umgca weseli we-ZF-L. Uhlalutyo lwe-in vitro luphande iithagethi ezintathu zeselula (ingqibelelo ye-membrane yeseli, umsebenzi we-mitochondrial kunye nokuzinza kwe-lysosomal) kwiiseli ezivezwe kugxininiso lwe-Roundup Transorb® (67.7 μg L (-1), 135.4 μg L (-1) ...
I-Glyphosate-based herbicides zezona zixhaphakileyo zisetyenziswa kwihlabathi liphela kuba ziyasebenza kwaye azinabungozi kwiintlobo ezingajoliswanga. Ukusetyenziswa ngokungenamkhawulo nokungalawulekiyo kwezi zibulali-zinambuzane ezinjalo kunokuba nemiphumo emibi kwimpilo yabantu kunye nokulungelelana kwendalo. Uphononongo lwangoku luvavanye ubutyhefu obubukhali kunye ne-genotoxicity ye-2 glyphosate-based formulations, i-Roundup Original (Roundup) kunye ne-Glyphosate AKB ...
Ubungqina obucacileyo: Ubunjineli bemfuzo, obukwabizwa ngokuba luguqulo lwemfuza, lujongene neemfuno ezikhulayo zendalo yasemanzini kunye neemveliso zasemanzini. Nangona ii-aquatics ezahlukeneyo ze-genetic modified (GM) zenziwe, kubalulekile ukuvavanya i-biosafety ye-GM organisms kwimpilo yabantu ngaphambi kokungena kwikhonkco lethu lokutya. Ngale njongo, siseka i-zebrafish endle yokutya kwabantu abadala…
Ubungqina obucacileyo: Nangona i-glyphosate ye-herbicide [N-(phosphonomethyl) glycine] ayihlelwanga njenge-acethylcholinesterase inhibitor, ezinye izifundo ziye zabika ukunciphisa umsebenzi we-acethylcolinesterase emva kokuvezwa kwe-vivo kuzo zombini ifom ecocekileyo kunye nokuqulunqwa kwayo kwezorhwebo. Ukuqwalasela le mpikiswano, injongo yolu phononongo yangoku yayikukuphanda, i-in vitro, iziphumo zokuvezwa kwe-glyphosate ...
Amagama angundoqo: Iintlanzi zihlala emanzini angcolileyo. Kwimizila emithathu yasezidolophini, enentlanzi yaseBritish Columbia, eCanada, sifumene izithako ezisebenzayo ze-WeedEx, i-KillEx, kunye ne-Roundup ye-herbicide formulations (i-2,4-D, i-dicamba, i-glyphosate, kunye ne-mecoprop) ephantsi ukuya kwi-ng / L yoxinaniso. (0.26 ukuya ku-309 ng/L) kwiimeko zesiqhelo, oko kukuthi, akukho mvula ubuncinane iveki enye. …
