Essential oil from the aerial parts of Centaurea cuneifolia Sibth. & Sm. and C. euxina Velen., two species growing wild in Bulgaria
2009
Abstract The volatile constituents of the aerial parts of Centaurea cuneifolia Sibth. & Sm. and Centaurea euxina Velen. from Bulgaria were extracted by hydrodistillation and were analyzed. The main components in C. cuneifolia were β-eudesmol (26.5%) and hexadecanoic acid (17.6%). The main components in C. euxina were hexadecanoic acid (20.3%), spathulenol (10.8%) and caryophyllene oxide (6.2%). The chemotaxonomic significances with respect to other previously studied species of the same sections ( Achrolopus and Phalolepis , respectively) are discussed.
Bezūdens kalcija hidrogēnfosfāta izmantošana zopiklona tablešu ražošanā
2015
Bezūdens kalcija hidrogēnfosfāts ir plaši izmantota palīgviela, ko izmanto farmācijā, medicīnā un pārtikas ražošanā. Bezūdens kalcija hidrogēnfosfāts nodrošina zopiklona tablešu presēšanās spēju, bet tā fizikāli-tehnoloģiskās īpašības var ietekmēt tabletes mehānisko izturību un pašu tabletes ražošanas procesu. Šajā darbā tika pētīta bezūdens kalcija hidrogēnfosfāta ietekme uz izplatītu nebenzodiazepīna klases miega līdzekli zopiklonu tablešu kvalitatīvajiem rādītājiem. Bezūdens kalcija hidrogēnfosfāta kvalitatīvo rādītāju noteikšanai tika izmantotas metodes: mikroskopija, daļiņu lieluma sadalījuma noteikšana ar lāzerdifrakciju, sietu analīze, birstošu vielu tilpuma blīvuma noteikšana un vie…
Nanofibrillar scaffold resists to bile and urine action: experiences in pigs
2020
Biomaterial-based-scaffolds’ functions are to replace anatomical and functional features loss of an injured tissue. They can replace native tissue after their reabsorption. Material and methods. In our experimental procedures we utilized the PHEA-PLA+PCL scaffold in 2 female pigs to assess its resistance to bile and urine. Results. Both pigs survived to surgical procedures. After a month fibres appeared unchanged in term of form and dimension at electronic microscopy. Cells and ECM factors were founded inside the scaffold in a microscopical evaluation. Conclusion. Planar and tubular scaffolds were colonized by cells and extracellular matrix elements. The study conducted on pig suggested tha…

Willingness to Adopt Biochar in Agriculture: The Producer’s Perspective
2017
Most research on biochar has focused either on the mechanistic or the biophysical aspects, and there has been relatively little research into the social applicability and acceptance of biochar as a soil enhancer in agriculture. However, whether to adopt biochar in their practice is ultimately the farmers’ decision, and their willingness to do so is crucial. Here, we show the producer’s perspective on adopting biochar, using Polish farmers as a case study. Poland is an interesting case study because biochar has only recently attracted the attention of researchers, entrepreneurs, and other stakeholders there. We performed standardized, semi-structured interviews with 161 Polish farmers to eva…

Staphylococcus epidermidis biofilmu veidošana un rezistences pret meticilīnu noteikšana, lietojot fenotipiskās un molekulāri bioloģiskās izmeklēšanas…

Staphylococcus epidermidis ir veselas cilvēka ādas un gļotādas dabiskās mikrofloras sastāvdaļa, kas ir viens no visbiežāk sastopamajiem cilvēka mikrobioma pārstāvjiem. Epidermālais stafilokoks ir oportūnists, kas saimniekorganismam spēj kolonizēt gan ādu, gan gļotādu. Kaut arī S. epidermidis piemīt mazāk virulences faktoru, nekā radiniekam S. aureus, epidermālais stafilokoks ir kļuvis par vienu no visbiežāk izolētajiem koagulāzes negatīvajiem stafilokokiem intrahospitālajā vidē. Tomēr neskatoties uz to, ka epidermālajam stafilokokam ir mazāk virulences faktoru, tas ir kļuvis par nopietnu un komplicētu problēmjautājumu gan ārstniecības iestādēm, gan sabiedrības veselībai kopumā. Pētījuma mēr…
Organic and chemical n fertilization on coriander (coriandrum sativum L.) in a Mediterranean environment
2014
Abstract Coriander (Coriandrum sativum L.) is an annual herbaceous Medicinal and Aromatic Plant (MAP) dealing with a great industrial interest because of its strongly-scented fruits (“seeds”). The role of N fertilization in coriander seed yield is matter of debate as far; information is missing, for instance, about the effects of organic N fertilization, a mandatory technique when the organic cropping management is chosen. Organic and chemical N fertilizers have been supplied on coriander from 2001–2002 to 2006–2007 in a Mediterranean semi-arid environment, and their effects on the formation of biomass and seeds yield have been evaluated. Different organic fertilizers, allowed by EU regulat…
Gut Microbiome Analysis In Adult Tropical Gars (Atractosteus tropicus)
2019
AbstractTropical gar (Atractosteus tropicus), is freshwater and estuarine fish that has inhabited the Earth since the Mesozoic era, undergoing limited physiological variation ever since. This omnivorous fish is endemic to southern Mexico and part of Central America. Besides its recognized cultural and scientific relevance, the species has seen remarkable growth in its economic impact due to pisciculture. Previous studies have highlighted the role of microbial communities in fish, particularly those in the gut microbiome, in maintaining their host homeostasis or disease. In this study, we present the first report of the whole taxonomic composition of microbial communities in gut contents of …
