Melleņu ģints ogu izspiedu ekstraktu neiroprotektīvie efekti SH-SY5Y šūnu modelī

2022

Mūsdienās pieaug interese par Vaccinium spp. ogu izspiedām, kā par potenciālu veselībai nozīmīgu ar fitoķīmiskām vielām bagātu avotu. Neirodeģenerācija ir patoloģisku procesu kopums, kas izraisa neironu nāvi, tāpēc tā novēršanai tiek meklēti neiroprotektīvi savienojumi. Darba mērķis ir pētīt piecu Vaccinium spp. ogu izspiedu ekstraktu acetilholīnesterāzes inhibīciju bezšūnu un SH-SY5Y šūnu modeļos un šūnu izdzīvošanas stimulāciju ar terciālā butilhidroksiperoksīda izraisītā oksidatīvā stresa apstākļos. Visi ogu ekstrakti inhibēja acetilholīnesterāzes aktivitāti, kā arī uzlaboja SH-SY5Y šūnu dzīvotspēju oksidatīvā stresa modelī. Augstāka acetilholīnesterāzes inhibīcija bija novērojama SH-SY5…

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…

The crustacean fauna of Bayan Onjuul area (Tôv Province, Mongolia) (Crustacea: Branchiopoda, Copepoda, Ostracoda)

2015

Due to the wide extension of the country and to the shortness of the ice-free season, the inlandwater crustacean fauna of Mongolia is, to date, incompletely known. However, based on the available literature, Mongolian inland waters appear to be characterised by a high biodiversity, including some taxa still waiting to be described. Novel data on the branchiopod, copepod, and ostracod crustaceans from central Mongolian steppe, from the “Tuul” and “Umard goviin guveet-Khalhiin” hydrographical basins, are presented herein. While large branchiopods, some anomopod families, and copepods are well-represented in the collected samples, ostracods are rare, and the anomopod family Chydoridae is appar…

Activity of bacterial seed endophytes of landrace durum wheat for control of Fusarium foot rot

2022

Five bacterial endophytic isolates obtained from durum wheat seeds (landrace “Timilia reste nere”) and identified as belonging to Pantoea (isolates A1, F7, F15 and G1) and Paenibacillus (isolate B) genera on the basis of 16S rDNA gene sequences, were assayed in vitro and in vivo for their ability to inhibit Fusarium culmorum growth and the disease (Fusarium foot rot) it causes in durum wheat. All isolates significantly reduced in vitro growth of F. culmorum in comparison with the control. After 120 hours of incubation, isolates B and G1 showed the greatest mycelial growth inhibition, i.e., respectively, 76 and 74%. When durum wheat “Simeto” seeds were treated with bacterial isolates singly …

Feeding strategy of the sacoglossan opisthobranch Oxynoe olivacea on the tropical green alga Caulerpa taxifolia.

2007

The feeding behaviour of the shelled sacoglossan Oxynoe olivacea was investigated to better understand the role and importance of this species in influencing encroachments of the alien alga Caulerpa taxifolia in the Mediterranean sea. We tested whether this slug preferred, as preliminary field observations suggested, an aggregative feeding behaviour and which part of the algal thallus, phylloid vs rhizoid, it preferred. Results showed that O. olivacea fed in groups and actively selected phylloid. This outcome poses important questions regarding the possibility that this species, fragmenting the alga thallus, could enhance dispersion and regeneration of C. taxifolia.

Haemolymphatic parameters in two aquaculture crustacean species Cherax destructor (Clark, 1836) and Cherax quadricarinatus (von Martens, 1868)

2021

The growing demand for animal proteins of aquatic origin such as fish, molluscs and crustaceans have prompted some European and Italian companies to focus their attention on some species of freshwater crustaceans such as Cherax destructor and Cherax quadricarinatus. They are among the largest freshwater decapods, matures early, females can lay over a thousand eggs in a single brood and has a broad environmental tolerance. All these characteristics make it highly appreciated species for aquaculture and few years ago their breeding has spread to Europe and recently also in Italy (Sicily). Although some commercial yabby farms have been studied these species from different points of view (dieta…

Vaccinium sugu ogu spiedatlieku ekstraktu efekti uz alfa - amilāzes aktivitāti in vitro

2018

Alfa – amilāzes un alfa – glikozidāzes enzīmi ir iesaistīti ogļhidrātu pārstrādes procesā, un to inhibēšana var samazināt glikozes līmeni asinīs, kas īpaši svarīga diabēta slimniekiem, lai novērstu postsprandiālo hiperglikēmiju. Ir atrastas vairāk nekā 1200 augu valsts sugas, kas atzītas par antidiabētiskiem līdzekļiem. Darba mērķis ir izpētīt melleņu, krūmmelleņu, lielogu dzērveņu, purva dzērveņu un brūkleņu alfa – amilāzes aktivitātes inhibīcijas spēju. Salīdzināti tika ogu ekstraktu ūdens un metanola šķīdumu efektivitāte, izmantojot kolorimetrisko metodi. Pētījuma rezultāti apliecina, ka visi ogu ekstrakti inhibē alfa – amilāzi, bet metanolā šķīstošā frakcija izrādījās aktīvāka nekā ūden…

Invasive Alien Species and Their Effects on Marine Animal Forests

2020

Nonindigenous species are increasingly transported around the world through multiple pathways by a diversity of vectors. Invasive species are a subset of those that are introduced into the receptor community, where they establish and increase their population to a size where they impact the native system. Marine invasive species can therefore interact with and modify native animal forests and/or create novel ones resulting in simple-to-complex changes in material cycling, energy flow, ecosystem structure, and function. Despite the ever increasing number of studies dealing with marine invasive species, mostly biological invasions are mentioned generically as one of a number of threats of dir…
