Android lietotne pārbaudījumu izveidei un kopīgošanai
2018
Android lietotnes “CreaTEst” mērķis ir apvienot izglītības iestāžu darbiniekus, entuziastus, kuriem ir vēlme dalīties labās prakses piemēros, komunicēt un iedvesmot. Šāds risinājums ļaus ieviest pārmaiņas pirmsskolas un skolas izglītības iestāžu mācību procesā. Lietotne tiek izstrādāta Java programmēšanas valodā Android Studio izstrādes vidē. Kvalifikācijas darba ietvaros tiks izstrādāti 3 moduļi, kas ļauj publicēt pārbaudījumu jautājumus, kurus izdomājis pats lietotājs. Par katru pievienoto testu autoram ir iespēja saņemt atsauksmes un ieteikumus no pārējiem lietotājiem. Tāpat lietotne sniedz iespēju lejupielādēt testu PDF formātā, lai vēlāk izdrukātu un izsniegtu mācību stundā. Datu glabā…
Automated GUI Testing for Android Applications
2012
Mobiililaitteet ovat yhä tärkeämmässä asemassa yhteiskunnassamme. Kun mobiililaitteiden käyttäjien määrä kasvaa, samoin kasvaa tarve sovelluksien paremmalle laadunvarmistukselle. Testauksen automatisointi on yksi avaintekijöistä sovelluksien laadun parantamiseen. Tämä tutkimus on kirjallisuuskatsaus Android-ohjelmien graafisten käyttöliittymien testauksen automatisaation nykytutkimuksesta. Mobile devices are becoming more and more important in our society. As the number of mobile device users grows, so does the importance of proper application quality control and verification. Test automation is one of the key factors in increasing application quality. This paper is a literature review on c…
Vienotas platformas izstrāde Android mobilo ierīču komunikācijas lietotņu testēšanā
2020
Maģistra darba ietvaros ir izveidota veiktspējas testu automatizācijas platforma Android ierīcēm, kura apvieno audio, tīkla ierobežošanas un tveršanas un baterijas patēriņa testus. Papildus tika veikta literatūras analīze un izzināti interneta resursi par to vai eksistē rīks, platforma, kas atbalsta dažāda veida veiktspējas testu automatizāciju, to izveidošanu un izpildi. Tika ievākta informācija par veiktspējas testu (audio, tīkla ierobežošanas un tveršanas un baterijas patēriņa testiem) galvenajām metrikām un iespējām tās noteikt. Pēc tam tika izpētīta un apkopota informācija par veiktspējas testu automatizācijas iespējām un nepieciešamajiem parametriem to veikšanai. Kas tālāk kalpoja par…
Central role of IL-6 and MMP-1 for cross talk between human intestinal mast cells and human intestinal fibroblasts.
2012
Mast cells (MC) are key effector cells in allergic reactions but also involved in host defence, tissue remodeling, angiogenesis, and fibrogenesis. Here, we show that human intestinal fibroblasts (FB) suppress apoptosis in human intestinal MC dependent on IL-6. Intestinal FB produced IL-6 upon direct stimulation by intestinal MC in co-culture or by MC mediators such as TNF-α, IL-1β, tryptase or histamine. MC incubated with IL-6 survived for up to 3 weeks similar to MC co-cultured with FB and MC survival could be blocked by neutralizing anti-IL-6 Abs. Moreover, FB stimulated by MC mediators upregulated their expression of matrix metalloproteinase-1 (MMP-1), a key fibrolytic enzyme. Noteworthy…
Angiotensin II positively modulates the spontaneous contractile activity of mouse and human colon via activation of AT1 receptors.
2012
Objective: Angiotensin II (Ang II) is a potent smooth muscle contractile neurohumoral agonist but has not been much investigated with regard to gastrointestinal motor activity. Ang II effects are mediated by specific receptors, the Ang II type 1 (AT1) and the Ang II type 2 (AT2) receptors, which are well expressed in the gut. In this study we evaluated the effects of Ang II on the contractile activity of longitudinal muscle from mouse and human colon and we analysed the subtype(s) of receptors involved in the observed effects. Methods: Mechanical responses to Ang II, in the absence or in the presence of different drugs, were assessed in vitro in colonic longitudinal muscle from mice and hum…
Intralaboratory validation of four in vitro assays for the prediction of the skin sensitizing potential of chemicals
2011
Abstract Allergic contact dermatitis is induced by repeated skin contact with an allergen. Assessment of the skin sensitizing potential of chemicals, agrochemicals, and especially cosmetic ingredients is currently performed with the use of animals. Animal welfare and EU legislation demand animal-free alternatives reflected in a testing and marketing ban for cosmetic ingredients beginning in 2013. The underlying mechanisms of induction and elicitation of skin sensitization are complex and a chemical needs to comply several properties being skin sensitizing. To account for the multitude of events in the induction of skin sensitization an in vitro test system will consist of a battery of vario…
A preliminary study in Wistar rats with enniatin : A contaminated feed
2014
A 28-day repeated dose preliminary assay, using enniatin A naturally contaminated feed through microbial fermentation by a Fusarium tricinctum strain, was carried out employing two months-old female Wistar rats as in vivo experimental model. In order to simulate a physiological test of a toxic compound naturally produced by fungi, five treated animals were fed during twenty-eight days with fermented feed. As control group, five rats were fed with standard feed. At the 28th day, blood samples were collected for biochemical analysis and the gastrointestinal tract, liver and kidneys were removed from each rat for enniatin A detection and quantitation. Digesta were collected from stomach, duode…
Brief Report: Intestinal dysbiosis in ankylosing spondylitis
2015
Objective Ankylosing spondylitis (AS) is a common, highly heritable immune-mediated arthropathy that occurs in genetically susceptible individuals exposed to an unknown but likely ubiquitous environmental trigger. There is a close relationship between the gut and spondyloarthritis, as exemplified in patients with reactive arthritis, in whom a typically self-limiting arthropathy follows either a gastrointestinal or urogenital infection. Microbial involvement in AS has been suggested; however, no definitive link has been established. The aim of this study was to determine whether the gut in patients with AS carries a distinct microbial signature compared with that in the gut of healthy contro…
In Vitro Bioavailability of Phenolic Compounds from Five Cultivars of Frozen Sweet Cherries (Prunus aviumL.)
2008
The bioavailability of phenolic compounds from five cultivars of frozen sweet cherries was assessed by a digestion process involving pepsin-HCl digestion (to simulate gastric digestion) and pancreatin digestion with bile salts (to simulate small intestine conditions) and dialyzed to assess serum- and colon-available fractions. After pepsin digestion, the % recovery of total phenolics, relative to the original starting material, increased, whereas the % anthocyanins did not change. Following pancreatic digestion and dialysis, the total phenolics in the IN (serum-available) fraction was about 26–30% and the OUT (colon-available) fraction was about 77–101%. The anthocyanin content in the IN fr…
Factors leading to dissemination of cutaneous anthrax: an international ID-IRI study
2022
Background: Although anthrax is a rare zoonotic infection, it still causes significant mortality and morbidity. In this multicenter study, which is the largest anthrax case series ever reported, we aimed to describe the factors leading to dissemination of cutaneous anthrax.Methods: Adult patients with cutaneous anthrax from 16 referral centers were pooled. The study had a retrospective design, and included patients treated between January 1, 1990 and December 1, 2019. Probable, and confirmed cases based upon CDC anthrax 2018 case definition were included in the study. A descriptive statistical analysis was performed for all variables.Results: A total of 141 cutaneous anthrax patients were i…
