Green synthesis and optimization of selenium nanoparticles using chitosan or cationic cellulose nanofibers
Spherical selenium nanoparticles (Se NPs) were synthesized by green chemical reduction method using biocompatible chitosan (CS) or as reported herein for the first time, cationic cellulose nanofibers (CCNFs) as stabilizers. ...
Development of high-performance binderless fiberboards from wheat straw residue
This study aims to develop fully bio-based lignocellulosic fiberboards from wheat straw fibers without any additional bonding agents. The wheat straw biomass was used to produce a semichemical pulp, which was treated by ...
Mitigation of almond leaf scorch by a peptide that inhibits the motility of Xylella fastidiosa
Xylella fastidiosa is a xylem-limited plant pathogenic bacterium that is a menace to the agriculture worldwide threating economically relevant crops such as almond. The pathogen presents a dual lifestyle in the plant xylem, ...
Texture-Driven Reformulation of Pork Liver Mousse with Reduced Allergenic Components
Since allergies associated with the consumption of pork are rare, this work proposes to use a pork liver extract with a neutral odour and excellent foaming properties both to reduce the presence of liver in the formulation ...
Coexistència entre blat de moro convencional i transgènic: influència de la data de sembra en la coincidència de la floració
L'autorització de cultius transgènics de blat de moro a la Unió Europea ha propiciat l'aparició del concepte de coexistència definit com el dret que tenen els agricultors de poder escollir entre la producció de cultius ...
Multiplex Polymerase Chain Reaction-Capillary Gel Electrophoresis: A Promising Tool for GMO ScreeningAssay for Simultaneous Detection of Five Genetically Modified Cotton Events and Species
A multiplex polymerase chain reaction assay coupled to capillary gel electrophoresis for amplicon identification by size and color (multiplex PCR-CGE-SC) was developed for simultaneous detection of cotton species and 5 ...
Antioxidant and antimicrobial emulsions with amphiphilic olive extract, nanocellulose-stabilized thyme oil and common salts for active paper-based packaging
Anionic cellulose nanofibers (CNFs) were used to stabilize emulsions that combined water-soluble (and oil-soluble), strongly antioxidant extracts with a water-immiscible, notably antimicrobial essential oil. Specifically, ...
A molecular beacon-based real-time NASBA assay for detection of Listeria monocytogenes in food products: role of target mRNA secondary structure on NASBA design
A molecular beacon-based real-time NASBA (QNASBA) assay for detection and identification of Listeria monocytogenes has been developed. A correlation between targeting highly accessible mRNA sequences and QNASBA efficiency ...
Efficient sequence-specific purification of Listeria innocua mRNA species by triplex affinity capture with parallel tail-clamps
Parallel clamps can interact in a sequence-specific manner with homopyrimidine DNA and RNA oligonucleotides to form triplexes. For longer nucleic acids, we have previously demonstrated the inhibitory effect of DNA-target ...
A new PCR-CGE (size and color) method for simultaneous detection of genetically modified maize events
We present a novel multiplex PCR assay for simultaneous detection of multiple transgenic events in maize. Initially, five PCR primers pairs specific to events Bt11, GA21, MON810, and NK603, and Zea mays L. (alcohol ...
Influència dels renadius en el contingut d’OGM a causa de la pol·linització creuada
Els renadius són plantes germinades a partir de grans aïllats, fragments de panotxa o panotxes senceres que cauen a terra durant la collita anterior. Així, si un any se sembra una varietat de blat de moro transgènica i ...
Coexistència en situació real entre blat de moro transgènic i convencional: resultats del seguiment realitzat els anys 2004, 2005 i 2006 en la zona de conreu de Foixà (Baix Empordà)
El blat de moro transgènic resistent al barrinador, conegut com a Bt, es va començar a cultivar a Espanya l'any 1998. Des d'aleshores, la superfície conreada ha augmentat any rere any, arribant al 2007 a les 75.148 ha, ...
Study of cork from Quercus suber L. with and without yellow spot: aromatic fraction and cellular structure
The effect of the presence of yellow spot in cork from Quercus suber was studied in relation to volatile compounds and the influence on the cellular structure to better understand cork as a material. The volatile compounds ...
Use of omics analytical methods in the study of genetically modified maize varieties tested in 90 days feeding trials
Genetically modified (GM) maize and their non-modified counterparts were compared using MON810 varieties, the only GMO event cultivated in Europe. The differences in grain samples were analysed by omics profiles, including ...
Asynchronous flowering or buffer zones: technical solutions for small-scale farming
To ensure consumers' and farmers' freedom of choice, many countries have regulated the labelling of products derived from genetically modified (GM) crops and coexistence of conventional and GM fields. On the basis of ...
Only half the transcriptomic differences between resistant genetically modified and conventional rice are associated with the transgene
Besides the intended effects that give a genetically modified (GM) plant the desired trait, unintended differences between GM and non-GM comparable plants may also occur. Profiling technologies allow their identification, ...
'Parallel' and 'antiparallel' tail-clamps increase the efficiency of triplex formation with structured DNA and RNA targets
Sequence-specific triple-helix structures can be formed by parallel and antiparallel DNA clamps interacting with single-stranded DNA or RNA targets. Single-stranded nucleic acid molecules are known to adopt secondary ...
Interlaboratory transfer of a real-time polymerase chain reaction assay for quantitative detection of genetically modified maize event TC-1507
A real-time polymerase chain reaction (QPCR) assay was developed for quantitative detection of a genetically modified (GM) maize event TC-1507 and modification to conventional PCR for qualitative purposes. Sequences 5 ...
Specific cleavage of Hepatitis C Virus RNA genome by human RNase P
We have found that RNase P from HeLa cells specifically and efficiently cleaves hepatitis C virus (HCV) transcripts in vitro. The evidence includes identification of the 5 -phosphate polarity of the newly generated termini ...
Recovery of Potassium-Rich Struvite in a Pig Farm Downstream a Nitrogen Removal Treatment Plant: Technological, Agricultural and Economic Assessment
Simultaneous recovery of phosphorus (P), potassium (K), and magnesium (Mg) as precipitated phosphate salt (PPS) wasassessed (K-struvite and hazenite included) in a pig farm downstream a nitrification-denitrification unit. ...
