Single-chain antibodies against a plant viral RNA-dependent RNA polymerase confer virus resistance.
2004
Crop loss due to viral diseases is still a major problem for agriculture today. We present a strategy to achieve virus resistance based on the expression of single-chain Fv fragments (scFvs) against a conserved domain in a plant viral RNA-dependent RNA polymerase (RdRp), a key enzyme in virus replication. The selected scFvs inhibited complementary RNA synthesis of different plant virus RdRps in vitro and virus replication in planta. Moreover, the scFvs also bound to the RdRp of the distantly related hepatitis C virus. T(1) and T(2) progeny of transgenic lines of Nicotiana benthamiana expressing different scFvs either in the cytosol or in the endoplasmic reticulum showed varying degrees of r…
Genome sequence of SeIV-1, a novel virus from the Iflaviridae family infective to Spodoptera exigua
2011
Analysis of the transcriptome of Spodoptera exigua larvae revealed the presence of several ESTs with homology to virus of the order Picornavirales and with the highest similarity to Infectious flacherie virus (Iflaviridae) that infects Bombyx mori larvae. Iflaviridae is a recently defined family of insect-infecting viruses that consist of positive single strand RNA genomes translated into a single polyprotein of around 3000 amino acids long. Using the sequence information derived from the obtained ESTs, we have completed the genomic sequence of this virus. The novel S. exigua iflavirus (SeIV-1) has a genome of 10.3 kb and codes for a 3222 aa polyprotein. Expression analysis has revealed the…
A single tube PCR assay for detecting viruses and their recombinants that cause tomato yellow leaf curl disease in Mediterranean basin
2007
Tomato yellow leaf curl disease (TYLCD) is well known in Mediterranean countries, where it has been causing severe losses in tomato crops for decades. Until recently, two viruses (with several isolates) in the genus Begomovirus, family Geminiviridae, have been associated with the epidemics: Tomato yellow leaf curl virus (TYLCV) and Tomato yellow leaf curl Sardinia virus (TYLCSV). However, recombinants between these, such as Tomato yellow leaf curl Malaga virus (TYLCMalV), are spreading, and new methods for detecting all viruses present in the region are needed. By considering all DNA sequences available of viruses causing TYLCD in the Mediterranean basin, a PCR/RFLP protocol was developed t…
On the Dynamics of Fractional Visco-Elastic Beams
2012
With increasing advanced manufacturing process, visco-elastic materials are very attractive for mitigation of vibrations, provided that you may have advanced studies for capturing the realistic behavior of such materials. Experimental verification of the visco-elastic behavior is limited to some well-known low order models as the Maxwell or Kelvin models. However, both models are not sufficient to model the visco-elastic behavior of real materials, since only the Maxwell type can capture the relaxation tests and the Kelvin the creep tests, respectively. Very recently, it has been stressed that the most suitable model for capturing the visco-elastic behavior is the spring-pot, characterized …

Cultura visuale. Una genealogia
2020
Questo libro offre una ricognizione delle principali genealogie novecentesche della cultura visuale, scegliendo solo tre figure paradigmatiche: Aby Warburg, Sigmund Freud e Walter Benjamin. Dopo Warburg la nozione di immagine è definitivamente cambiata. Dopo Freud lo sguardo è indissolubilmente legato al tema della sessualità e del bios. Dopo Benjamin la nozione di dispositivo e quelle di apparato, assemblage e ambiente mediale sono definitivamente cambiate. Questi autori non stanno solo alle origini della cultura visuale ma ne prefigurano gli sviluppi futuri. Da Warburg abbiamo imparato che il fare-immagine fa parte della biologia e dei comportamenti essenziali dell’Homo sapiens, un aspett…
Il difficile bilanciamento tra tutela della madre vulnerabile, best interest del minore e diritti culturali della donna migrante al vaglio della Cort…
2021
Il contributo offre il commento di una recente della Corte Europea dei Diritti dell’Uomo riguardante un caso di violazione del diritto alla vita privata e familiare, di cui all’art. 8 della Convenzione Europea dei Diritti dell’Uomo, da parte della Repubblica Italiana. L’autrice ricostruisce i principali fatti che caratterizzano il caso concreto e le questioni di diritto sottoposte all’attenzione della Corte, analizzando la sentenza in commento sulla base di due essenziali nodi logico-argomenta- tivi: il primo riguarda il difficile contemperamento tra i valori protetti dalla normativa in materia di adozione e il diritto di genitori e figli a mantenere in vita, per quanto compatibile con il b…
Lipid-related thiamine deficiency cause mortality of river lampreys (Lampetra fluviatilis) during pre-spawning fasting
2023
Publisher Copyright: © 2023 The Authors River lampreys (Lampetra fluviatilis) were caught in the fall 2014 on entering the River Perhonjoki for spawning and kept at a hatchery until spawning in late spring 2015 to produce larvae for compensatory stockings. Since the lampreys died massively from early February onwards, they were investigated in March and May to clarify the cause of the deaths. The symptoms in lampreys resembled those of lipid-related thiamine (vitamin B1) deficiency of salmonines, called the M74 syndrome in the Baltic Sea area. Because the lipid content of lampreys was known to be high, thiamine concentrations were analyzed in the liver and ovulated unfertilized eggs, and th…

Risk of threats in the Opolskie Voivodeship and the awareness of residents
2019
Województwo opolskie zostało dotknięte powodzią nazywaną również ,,powodzią tysiąclecia” w 1997 r., lecz wielu mieszkańców pamięta te dotkliwe zdarzenia. Z pewnością od tego czasu wyciągnięto wiele wniosków i dokonano zmian w procedurach, niemniej jednak nawet najlepsza organizacja wymaga współpracy ludności cywilnej w momencie wystąpienia zagrożenia. Bez wiedzy mieszkańców na temat sposobów reagowania na poszczególne zagrożenia, nie można mówić o dobrym przygotowaniu. Stąd też niniejszy artykuł jest próbą przedstawienia zagrożeń mogących pojawić się na terenie województwa opolskiego oraz jedynie wskazania odpowiedzialnych pod- miotów wiodących, jak np. Wojewoda Opolski w fazie zapobiegania…
