Mobile forms of carbon in trees : metabolism and transport
(Oxford University Press, 2022-03)Plants constitute 80% of the biomass on earth, and almost two-thirds of this biomass is found in wood. Wood formation is a carbon (C)-demanding process and relies on C transport from photosynthetic tissues. Thus, understanding ... -
Antiviral efficacy of short-hairpin RNAs and artificial microRNAs targeting foot and-mouth disease virus
(Peer J Inc., 2021-06)RNA interference (RNAi) is a well-conserved mechanism in eukaryotic cells that directs post-transcriptional gene silencing through small RNA molecules. RNAi has been proposed as an alternative approach for rapid and specific ... -
Limited usefulness of the IS6110 touchdown-PCR in blood for tuberculin skin test false-negative cattle with serological response to Mycobacterium bovis
(Frontiers Media, 2024-05)Ante-mortem diagnosis of bovine tuberculosis (bTB) is based mainly on the tuberculin skin test (TST) and the ɣ-IFN release assay (IGRA). Some infected animals escape screening tests, thus, limit herd sanitation. Previous ... -
Enteroparasitosis en una población infantil del Municipio de Hurlingham, Buenos Aires = Enteroparasitosis in a child population of the Hurlingham District, Buenos Aires
(Fundación Revista Medicina, 2022-12)Introducción: Los parásitos intestinales tienen mayor impacto en las poblaciones infantiles ya que pueden, a largo plazo, conducir a un retraso en el crecimiento con alteración del desarrollo cognitivo. Sumado a esto, los ... -
Transmissibility of Mycobacterium pinnipedii in a murine model
(Frontiers Media, 2024-03)The causative agent of tuberculosis in pinnipeds is Mycobacterium pinnipedii, a member of the Mycobacterium tuberculosis complex (MTC). The natural hosts are pinnipeds; however, other non-marine mammals, including humans, ... -
Evasion of maternal antibody protection by an IBDV Argentine variant
(Elsevier, 2024-03)Infectious bursal disease (IBD) is a viral disease that affects the ability of chickens to produce humoral immune responses. One way to prevent the disease is the passage of maternally derived antibodies (MDA) from dams ... -
Live attenuated Mycobacterium bovis strains combined with the encapsulated H65 antigen as a vaccine strategy against bovine tuberculosis in a mouse model
(Elsevier, 2024-04)Mycobacterium bovis is an etiological agent of bovine tuberculosis (bTB) that also infects other mammals, including humans. The lack of an effective vaccine for the control of bTB highlights the need for developing new ... -
Unveiling the defensive role of Snakin‑3, a member of the subfamily III of Snakin/GASA peptides in potatoes
(Springer, 2024-02)Snakin/GASA proteins share 12 cysteines in conserved positions in the C-terminal region. Most of them were involved in different aspects of plant growth and development, while a small number of these peptides were reported ... -
Xylanase production by cellulomonas phragmiteti using lignocellulosic waste materials
(MDPI, 2024-02)Lignocellulosic biomass holds promise as a renewable feedstock for various applications, but its efficient conversion requires cost-effective degradation strategies. The main objective of this study was to investigate the ... -
Phylodynamic analysis of foot-and-mouth disease virus evolution in Mar Chiquita, Argentina
(Springer, 2024-05)Foot-and-mouth disease is a highly contagious disease affecting cloven-hoofed animals, resulting in considerable economic losses. Its causal agent is foot-and-mouth disease virus (FMDV), a picornavirus. Due to its error-prone ... -
Decreased immune response in undernourished rats after air pollution exposure
(Elsevier, 2024-04)Children are highly vulnerable subpopulation to malnutrition and air pollution. We investigate, in a rat nutritional growth retardation (NGR) model, the impact of Residual Oil Fly Ash (ROFA) on the lung immune response ... -
Tuberculosis in wild pigs from Argentina
(Springer, 2024)Mycobacterium bovis, a member of the Mycobacterium tuberculosis complex (MTC) and non-tuberculous Mycobacteria (NTM), may infect wild and domestic mammals, including humans. Although cattle are the main hosts and spreaders ... -
Coinfection of cotton plants with cotton leafroll dwarf virus atypical and a novel cotton begomovirus
(Wiley, 2024-05)Cotton is a commercial crop of global importance whose versatile fibre is widely used in the textile industry. Cotton is vulnerable to infectious pathogens, including viruses, that are a major threat to cotton production. ... -
TuMV infection alters the regulation of miR168/AGO1 and miR403/AGO2 systems in Arabidopsis
(Springer, 2024)Plant argonaute (AGO) proteins—chiefly AGO1 and 2—restrict viral infections. AGO1/2 also participate in developmental processes and are tightly regulated by microRNAs. Researchers have conducted extensive studies on the ... -
Unheard voices speak up : the Arabidopsis community and the representation of researchers from the Global South
(Oxford University Press, 2024-04)In June 2023, the Arabidopsis community met in Makuhari, Chiba, Japan, for the 33rd International Conference in Arabidopsis Research (ICAR). The meeting, at which more than 1200 researchers gathered, spanned the course of ... -
Assessing the impact of various tuberculin PPD brands on bovine tuberculosis diagnosis
(Springer Nature, 2024-03)Although several brands of tuberculin purified protein derivatives (PPDs) are available for diagnosing bovine tuberculosis (bTB), comparative studies to determine their diagnostic accuracy are infrequent. In Ecuador we ... -
Assessing small RNA profles in potato diploid hybrid and its resynthesized allopolyploid reveals conserved abundance with distinct genomic distribution
(Springer, 2024-04)Allopolyploidy, a complex process involving interspecific hybridization and whole genome duplication, significantly impacts plant evolution, leading to the emergence of novel phenotypes. Polyploids often present phenotypic ... -
Research Note : Characterization and phylodynamic analysis of new infectious bursal disease virus variants circulating in Argentina
(Elsevier, 2024-06)Infectious Bursal Disease is a highly contagious disease that affects young chickens and leads to significant economic losses. Its causal agent is a double-stranded RNA virus that, due to its high error rate during the ... -
Exploring the cellulolytic activity of environmental mycobacteria
(Elsevier, 2024-07)Although studies on non-tuberculous mycobacteria have increased in recent years because they cause a considerable proportion of infections, their cellulolytic system is still poorly studied. This study presents a ... -
