Do You Know What You Drink? Comparative Research on the Contents of Radioisotopes and Heavy Metals in Different Types of Tea from Various Parts of the World.

The aim of this study was to assess the potential health risks of radioactive elements and heavy metals ingested through the consumption of various types of tea imported to the Polish market (black, green, red, oolong and white). The concentrations [Bq/kg] of radionuclides (K, Cs, Ra, Pb and Th) in tea leaves before and after brewing were measured using γ-ray spectrometry with high-purity germanium (HPGe). The concentrations [mg/kg] of the studied elements (Fe, Cr, Cu, Mo, Al, Mn, Ni, P, V, Cd and Pb) were determined using a microwave-induced plasma optical emission spectrometer (MIP-OES).

Differences in protein profiles between strains obtained from healthy and infected dogs.

causes infections of the skin and mucous membranes, especially in individuals with metabolic, hormonal, and immunological disorders. The search for properties that differentiate isolates from healthy and infected animals may result in the identification of typically commensal and potentially pathogenic strains within the entire species. We aimed to determine and compare protein profiles of strains isolated from 30 dogs with clinical symptoms of otitis externa and 34 dogs without symptoms of any disease.

Oxythiamine improves antifungal activity of ketoconazole evaluated in canine Malassezia pachydermatis strains.

Background: Malassezia pachydermatis is an opportunistic yeast involved in skin and ear canal infections of dogs and cats. Reports suggest that strains of M. pachydermatis resistant to commonly used antifungal agents may be emerging.

Genetic relationships and population structure of Malassezia pachydermatis strains isolated from dogs with otitis externa and healthy dogs.

Malassezia pachydermatis causes infections of the skin and mucous membranes, especially in animals. It is commonly accepted that symptom manifestation depends on the physiological status of the host (different metabolic, hormonal, and immunological disorders). However, it should be considered whether distinct strains of M.

Thiamine and selected thiamine antivitamins - biological activity and methods of synthesis.

Thiamine plays a very important coenzymatic and non-coenzymatic role in the regulation of basic metabolism. Thiamine diphosphate is a coenzyme of many enzymes, most of which occur in prokaryotes. Pyruvate dehydrogenase and 2-oxoglutarate dehydrogenase complexes as well as transketolase are the examples of thiamine-dependent enzymes present in eukaryotes, including human.
