We present a multicore fiber dedicated for next generation transmission systems. To overcome the issue of fibers' integration with existing systems, is designed in such way that parameters each core (i.e., chromatic dispersion, attenuation, bending loss, etc.) are total accordance obligatory standards telecommunication single fibers ITU-T G.652 and G.657). show results numerical investigations measurements carried out fabricated fiber, which confirm low core-to-core crosstalk compatibility...
Recently, many studies have investigated the relationship between level of metals in body and various diseases. The objective this study was to examine any possible influence periodontal disease upon concentration oral fluid blood explore usability applying cluster analysis coupled with selected elements fluid, calcium (Ca), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), zinc (Zn), cadmium (Cd) lead (Pb), for effectively distinguishing people affected by periodontitis from healthy...
The authors would like to make the following correction published paper [...]
Head and neck cancers are one of the most frequent worldwide. This paper attempts to evaluate disturbances homeostasis necessary elements (calcium, magnesium, zinc, copper, iron, manganese) changes in levels toxic metals (lead, cadmium, cobalt, chromium VI) hair patients with head cancers, as well people without a diagnosed neoplastic disease. In order quantify metals, method using ICP-MS ICP-OES techniques had been developed validated. The studies have shown that cancer used drink alcohol...
Multi-walled carbon nanotubes (MWCNTs) serve as nanoparticles due to their size, and for that reason, when in contact with the biological system, they can have toxic effects. One of main mechanisms responsible nanotoxicity is oxidative stress resulting from production intracellular reactive oxygen species (ROS). Therefore, biomarkers are important tools assessing MWCNTs toxicity. The aim this study was evaluate multi-walled male rats. Our animal model studies (diameter ~15-30 nm, length...
Genetically uniform plant material, derived from Lychnis flos-cuculi propagated in vitro, was used for the isolation of 20-hydroxyecdysone and polypodine B subjected to an evaluation antifungal antiamoebic activity. The activity 80% aqueous methanolic extracts, their fractions, isolated ecdysteroids were studied against pathogenic Acanthamoeba castellani. Additionally, a Microtox® acute toxicity assay performed. It found that fraction root extract exerts most potent amoebicidal at IC50 0.06...
The discovery of perchlorate in martian regolith, ubiquitously distributed at levels far exceeding those noted on Earth, raises challenges for situ resource utilization and life-supporting systems. However, this challenge can be overcome by organisms with extreme tolerance to various stressors, characterization the mechanisms supporting such features, their subsequent employment biological systems using genetic engineering synthetic biology. Using could an excellent complement physical...
Tobacco smoking is a serious threat to life and health of society. Among the most vulnerable toxic effects tobacco smoke are foetuses newborns. The objective research was assess impact exposure on oxytocin levels biochemical oxidative stress parameters during pregnancy after birth in an experimental model.In experiment, gravid non-gravid rats monitored. A reliable biomarker - cotinine used process it determined by means high-performance liquid chromatography with diode array detection, which...
Sulfur mustard (SM) inhalation causes debilitating pulmonary injury in humans which progresses to fibrosis. Herein, we developed a rat model of SM toxicity parallels pathological changes the respiratory tract observed humans. vapor caused dose (0.2-0.6 mg/kg)-related damage within 3 days exposure. At 0.4-0.6 mg/kg, ulceration proximal bronchioles, edema and inflammation were observed, along with proteinaceous exudate containing inflammatory cells alveolar regions. Time course studies...
Lychnis flos-cuculi L. is a species containing ecdysteroids, triterpenoid saponins, flavonoids, and phenolic acids, therefore plant of potential medicinal value. In the presented research, diverse in vitro cultures this taxon were developed to obtain uniform material capable producing including micropropagated plantlets, shoot cultures, liquid agitated whole with fast-growing roots, callus. A protocol micropropagation through axillary bud formation was established using growth regulators at...
Phytoecdysteroids are natural compounds with therapeutic benefits in both humans and animals. The effectiveness of products health potential is based on the activities potencies their active ingredients. In this study, dominant ecdysteroids—ajugasterone C, 20-hydroxyecdysone polypodine B—from Serratula coronata (S. coronata) herb were separated by column chromatography, identified spectroscopic data quantified high-performance liquid chromatography a diode array detector (HPLC-DAD). obtained...
Endometriosis is a gynecological disease defined by the presence of endometrial tissue outside uterus. To date, effective treatment this still based on invasive surgery or laparoscopy. Chelidonium majus L. (Papaveraceae) belongs to medicinal, latex-bearing plants. Extracts from plant are rich source pharmacologically active agents. Protoberberine compounds derived C. possess anticancer and antiproliferative activities. In present study rat model endometriosis, we investigated influence...
Polydopamine nanoparticles (PDA NPs) have great potential in medicine. Their applications being widely investigated cancer therapy, imaging, chemotherapy, photodynamic therapy (PDT), photothermal (PTT), and tissue repair. The aim of our study was to assess the vivo toxicity changes oxidative stress biomarkers organs animals treated with mesoporous PDA NPs modified iron (MPDAFe NPs), coated cell membrane loaded doxorubicin (DOX), subsequently subjected PTT.
