The treatment of acne and other seborrheic diseases has arisen as a significant clinical challenge due to the increasing appearance of multi-drug resistant pathogens and a high frequency of recurrent lesions. Taking into consideration the fact that some species are valuable curatives in skin diseases in traditional medicine, we assumed that the thus far unstudied species and may be a source of active substances used in skin diseases. The purpose of this study was to evaluate the antioxidant, anti-inflammatory, antibacterial, and cytotoxic activities of their extracts and fractions.

The purpose of our study was to evaluate the composition of the extracts obtained from the roots and leaves of Eutrema japonicum cultivated in Poland. For this purpose, LC-DAD-IT-MS and LC-Q-TOF-MS analyses were used. The results revealed the presence of forty-two constituents comprising glycosinolates, phenylpropanoid glycosides, flavone glycosides, hydroxycinnamic acids, and other compounds.

Considering that miscellaneous species of are thought to be healing in traditional Asian medicine, we assumed that this uninvestigated species may reveal significant therapeutic properties. Here, we report the simultaneous assessment of chemical composition as well as biological activities (antioxidant, anti-inflammatory, antibacterial, and cytotoxic properties) of tested species.

As a consequence, it leads to an increase in the activation of extracellular matrix disruption enzymes and DNA damage. The search for natural sources that inhibit these mechanisms can be a good approach to prevent skin aging.

The aim of this study was to develop efficient extraction method for isolation of bioactive compounds from the Polish "Marynka" hop variety. The modified two-step supercritical fluid extraction allowed to obtain two hop samples, namely crude extract (E1), composed of α-acids, β-acids, and terpene derivatives, as well as pure xanthohumol with higher yield than that of other available methods.

Two commercial composites (Flow-Art-flow type with 60% ceramic filler and Boston-packable type with 78% ceramic filler; both from Arkona Laboratorium Farmakologii Stomatologicznej, Nasutów, Poland) were modified by addition of 5% by weight (of resin) of a liquid methacrylate-terminated polybutadiene. Results showed that modification of the flow type composite significantly ( < 0.

The Cip-Bi chemical structure was confirmed by Fourier transform infrared spectroscopic (FTIR) analysis. The sought after antibacterial wound dressing was obtained by modification of the raw dressing with an iodine or bromine solution and subsequently with a Cip-Bi hydrogel.

It is worth underlining that we are the first to characterize the composition and evaluate the biological properties of extracts from and Thus, the LC-DAD-MS analysis revealed the presence of 41 natural products in studied extracts. The 5--caffeoylquinic acid, isoorinetin, and swertiajaponin were the main detected compounds.

The agar and broth diffusion tests, visual TTC (triphenyltetrazolium chloride) method, and confocal scanning laser microscopic (CSLM) observations have shown highly satisfactory antimicrobial and antibiofilm activity of the novel sparfoxacin (SPA)-treated urinary catheters compared with the controversial effectiveness of silver(Ag)-coated catheters against a background of untreated catheters used as controls. SPA-treated catheters were significantly less likely to become colonized (less than 0.
