(MDPI, 2022-03)Babesia bovis, a tick-transmitted apicomplexan protozoon, infects cattle in tropical and subtropical regions around the world. In the apicomplexans Toxoplasma gondii and Plasmodium falciparum, rhomboid serine protease 4 ... -
Unravelling chemical cues used by Diachasmimorpha longicaudata (Hymenoptera: Braconidae ) during host search
(FAO-IAEA, 2022-11)Parasitoid wasps are attracted to their hosts using associated volatile compounds. In an static air olfactometer, it was shown that Diachasmimorpha longicaudata females oriented towards oranges with direct or indirect signs ... -
Unveiling the genetic basis of Sclerotinia head rot resistance in sunflower
(BMC, 2020-07)Background: Sclerotinia sclerotiorum is a necrotrophic fungus that causes Sclerotinia head rot (SHR) in sunflower, with epidemics leading to severe yield losses. In this work, we present an association mapping (AM) approach ... -
Unveiling the increasingly altered patterns of wetland ecosystem functional diversity in the lower Delta of the Paraná River
(Wiley, 2022-07-08)Since climate, environmental and anthropic controls affect ecosystem functioning simul taneously, wetlands are permanently changing at different spatio–temporal scales. Thus, regionalizations based not only on structural, ... -
Unweaving the population structure and genetic diversity of Canadian shrub willow
(Springer Nature, 2022-10-14)Perennial shrub willow are increasingly being promoted in short-rotation coppice systems as biomass feedstocks, for phytoremediation applications, and for the diverse ecosystem services that can accrue. This renewed interest ... -

Ursolic acid : a novel antiviral compound inhibiting rotavirus infection in vitro
(Elsevier, 2019-11)Rotavirus is one of the leading causes of severe acute gastroenteritis in children under 5 years of age, mainly affecting developing countries. Once the disease is acquired, no specific treatment is available; as such, the ... -
Use of 454-Pyrosequencing for the characterization of Sweet potato virus C and Sweet Potato Feathery Mottle virus Isolates fron Argentina and Development of a Multiplex one - step RT-PCR for Their Simultaneous Detection
(2016)454-pyrosequencing was applied as a tool to identify etiological agents involved in the symptoms observed in a sweet potato sample from Argentina. RNA was purified from symptomatic material and sequenced using a Roche 454 ... -
Use of adjuvant ISA VG 71 to produce neutralizing egg yolk antibodies against bothropic venom
(Springer, 2023-02)The use of egg yolk antibodies—IgY technology—represents an alternative to the production of mammalian immunoglobulins and has several advantages regarding animal welfare and lower costs of production. The use of adjuvants ... -
Use of Chelex-100 for the molecular diagnosisof five animal pathogens
(Facultad de Ciencias Veterinarias, Universidad Nacional del Litoral, 2021-06)Molecular tools have improved conventional veterinary diagnosis. Acid nucleic extraction is a key step for downstream applications. This work aimed to compare the DNA extraction method Chelex-100 resin (M1) ... -
Use of copper hydroxide in the cultivation of lisianthus seedlings (Eustoma grandiforum L.) under floating system
(2017)Previous experiences demonstrated the efficiency of the floating system for growing lisianthus (Eustoma grandiflorum L.) seedlings. Using this system, root growth usually expands through the plug cell drainage hole into ... -
Use of molecular tools for the diagnosis of rangeliosis by Rangelia vitalii in Argentina: A case report
(Elsevier, 2020-07)Vector-borne pathogens are responsible for serious emerging diseases and Rangelia vitalii, the etiologic agent of canine rangeliosis, is one of the most pathogenic tick-borne pathogens for dogs in South America. This ... -
Use of silencing reporter and agroinfiltration transient assays to evaluate the potential of hpRNA construct to induce multiple tospovirus resistance
(2015-12)Tospoviruses are devastating plant viruses causing severe economic losses in a diverse range of crops worldwide. Here, we describe the development and evaluation of an RNA interference (RNAi) broad-spectrum virus resistance ... -
