Significance of the physiological state of fungal spores.
2008
In predictive mycology, most of the studies have been concerned with the influence of some environmental factors on fungal growth and production of mycotoxins, at steady-state. However, fluctuating conditions, interactions between organisms, and the physiological state of the organisms may also exert a profound influence on fungal responses in food and in the environment. In the laboratory, fungal spores are widely used as a biological material. They are produced under optimal conditions then, partially re-hydrated for obtaining standardized spore suspensions. In real conditions, spores are produced under suboptimal conditions and can be submitted to various stresses prior to their germinat…
Emerging fungi and mycotoxins in crops in the framework of climate change. Design of strategies for their prevention and control
2015
Las micotoxinas son metabolitos secundarios fúngicos que se encuentran frecuentemente como contaminantes naturales en diversos alimentos habituales en la dieta humana y animal. Producen micotoxicosis agudas y crónicas que afectan principalmente al hígado, riñón y sistemas inmunológico y reproductor. Además, algunas de ellas como las aflatoxinas (AFLs) han sido reconocidas por la “International Agency for Research on Cancer” (IARC) como los compuestos naturales con mayor potencial teratogénico y cancerígeno para humanos que se conocen, a ellas le sigue la ocratoxina A (OTA), fumonisinas (FBs), deoxinivalenol (DON), zearalenona (ZEA), patulina (PAT) y citrinina (CIT). La IARC las ha clasifica…
Infección por mohos en pacientes con fibrosis quística. Impacto en su evolución clínica
2021
Antecedentes: Existen avances importantes en el manejo de la infección bacteriana en pacientes con fibrosis quística (FQ), pero hay muchas lagunas en el campo de las infecciones fúngicas. Objetivos: El objetivo del estudio fue analizar si la colonización respiratoria crónica por hongos filamentosos tenía impacto clínico y si el tratamiento antifúngico modificaba la enfermedad. Métodos: Estudio prospectivo, bicéntrico y descriptivo con un seguimiento de 3 años y controles médicos cuatrimestrales. Se incluyeron pacientes adultos de dos Unidades de Fibrosis Quística de hospitales terciarios. Se recogieron datos de variables clínicas, microbiológicas, analíticas y espirométricas; en un subgrupo…
Development of methods using phytoalexin (resveratrol) assessment as a selection criterion to screen grapevine in vitro cultures for resistance to gr…
1995
The purpose of this research was, firstly to determine the ability of grapevine in vitro cultures to synthesize resveratrol, a stilbene-type phytoalexin that is considered to be a good marker for resistance of grapevines to Botrytis cinerea, the causal organism for grey mould. Secondly, this study sought to establish the relationship between phytoalexin production potential and resistance to Botrytis cinerea in grapevines. In this aim, resveratrol production was assessed in 13 Vitis species or cultivars. A good correlation appeared between resveratrol production by grapevine in vitro cultures and grey mould resistance except for two Vitis spp. for which no correlation was observed, thus sug…
Gravity-derived Moho map for Latvia
2020
A precise understanding of crustal structure is essential to the fields of geodynamics, seismology and certain branches of geophysics. A boundary between the crust and the mantle is known as the MohoroviÄiÄ discontinuity, simply referred to as the âMohoâ. Moho geometry and depth have been extensively studied in Europe, but there are still regions with little information about it. One such area is the northern Baltics, Latvia in particular. So far, only one seismic refraction profile, spanning from Sovetsk (Kaliningrad) to Kohtla-Järve (Estonia), has been used to study the deep structure of the Earth in Latvia. We propose gravity inversion (ParkerâOldenburg algorithm) to gain more insight i…
Mohorovičiča virsmas modeļa izveide Latvijas teritorijai pēc gravitācijas lauka mērījumu datiem
2019
Maģistra darba “Mohorovičiča virsmas modeļa izveide Latvijas teritorijai pēc gravitācijas lauka mērījumu datiem” mērķis ir izveidot Zemes garozas biezuma modeli Latvijas teritorijai, izmantojot pieejamos gravitācijas lauka un seismisko profilu mērījumus. Pētījumā ar statistiskām metodēm veikta gravitācijas lauka mērījumu apvienošana vienā datu kopā. No gravitācijas datiem, Pārkera-Oldenburga inversijas algoritma un seismiskiem profila mērījumiem aprēķināts Mohrovičiča (Moho) virsmas modelis Latvijas teritorijai Izveidotais Zemes garozas biezuma modelis labi parāda galvenās biezuma izmaiņu tendences, bet nav pietiekoši precīzs, lai noteiktu mazas, neliela mēroga izmaiņas Moho virsmā. Modeļa …
