Aims: To examine the existing literature to determine the degree to which percutaneous absorption data obtained using the excised human skin model match those obtained from living man. Methods: The scientific literature was reviewed to collect data on compounds whose percutaneous absorption through human skin had been measured under both in vitro and in vivo conditions. The in vitro-in vivo (IV...

In this study, antioxidant and antimicrobial potentials of Usnea intermedia, U. filipendula, and U. fulvoreagens and their stictic and usnic acid contents were investigated. Antioxidant activity and total phenolic contents were evaluated in acetone, ethanol, and methanol extracts of these three species. Antioxidant activity was measured by ABTS [2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic...

New approaches for treatment of infectious diseases in aquatic animals have important roles in aquaculture technology progress. In the present study, In vitro effects of different extracts of propolis, royal jelly and pollen obtained from beehives have been investigated on aquatic pathogenic bacterial isolates. The isolated bacteria identified on the basis of their biochemical properties and se...

Algae are rich sources of amino acids, terpenoids, florentines, alkanes, halogenated ketones, steroidal compounds, fatty acids, and phenols that can be used in the pharmaceutical industry. The acetone and ethanol extracts, and the supernatant of the algae Chlorella vulgaris CCATM210-1, were used in this study. After culturing the Algae, and preparing the supernatant and extracts, the antibacter...

Objective: To investigate the difference of chemical bonds between urethane dimethacrylate (UDMA) bonding agents with ethanol solvent and acetone on dentin collagen. Material Methods: This experimental comparison study used three groups: G1 (Control): UDMA collagen; G2: UDMA, collagen ethanol; G3: acetone. The groups were then pelleted analysed FTIR, peak value carbonyl absorption band from eac...

Broadly tunable external cavity quantum cascade lasers (EC-QCLs) in combination with off-axis integrated cavity enhanced spectroscopy (OA-ICOS) provide high molecular gas sensitivity and selectivity. We used an EC-QCL in the region of 1150–1300 cm ́1 in both broadband scan mode, as well as narrow scanning mode around 1216 cm ́1, respectively, for detection of acetone in exhaled breath. This wavel...

Introduction: Rosa damascena mill L., well-known as Rose, has numerous pharmacological properties including antioxidant, antitussive, relaxant effect on tracheal chains, hypnotic, antibacterial and anti-HIV. Objective: The objective of the present study was to evaluate antioxidant and free radical scavenging activity of various extracts of Rose flower petals. Methods: Chloroform, acetone, ethan...
