Gels and liposomes in optimized ocular drug delivery: studies on ciprofloxacin formulations.
The polymer hydrogels used in the preparations ensured a steady and prolonged active ingredient release and encapsulation of the CPFX into liposomes prolonged the in vitro release of the antibacterial agent depending on the lipid composition of the vesicles. Expand
Quantitative determination of crystallinity of alpha-lactose monohydrate by Near Infrared Spectroscopy (NIRS).
NIRS can be used for the quantitative determination of crystallinity of materials during pharmaceutical procedures and showed that NIRS is an useful method for accurately determining low quantities of the crystalline lactose in a physical mixture. Expand
Comparative study of traditional essential oil and supercritical fluid extracts of Moldavian dragonhead (Dracocephalum moldavica L.)
The effectiveness and selectivity of different extraction procedures (hydrodistillation, Soxhlet extraction with organic solvents and supercritical fluid extraction) was compared. The main volatileExpand
Application of sucrose fatty acid esters in transdermal therapeutic systems.
In vitro studies indicated that SEs of shorter fatty acid chain length and higher HLB value increased the amount of released drug about 10 times and could be promising agents in transdermal therapeutic systems to control the drug release and cutaneous absorption. Expand
Evaluation of Drug Release From Coated Pellets Based on Isomalt, Sugar, and Microcrystalline Cellulose Inert Cores
The results demonstrated that, besides the ratio of the coating polymers (ERS/ERL), the release mechanism was also influenced by the type of starter core used, and sugar- and isomalt-type pellet cores demonstrated similar drug release profiles. Expand
Dissolution and diffuse reflectance characteristics of coated theophylline particles
The aim of the present study was to investigate how the dissolution and diffuse reflectance characteristics of theophylline microcapsules were influenced by the changes in the thickness and by theExpand
Multiple ABC Transporters Efflux Baicalin
By inhibition of transport by ABC transporters, baicalin could interfere with the absorption and disposition of drugs and is likely mediated by MRP3 and MRP4 both in enterocytes and hepatocytes. Expand
Estimation of the number of biophotons involved in the visual perception of a single-object image: biophoton intensity can be considerably higher inside cells than outside.
This paper argues that biophotons are not by-products, other than originating from regulated cellular radical/redox processes, and shows that the biophoton intensity can be considerably higher inside cells than outside. Expand
Development and characterization of the voriconazole loaded lipid‐based nanoparticles
The aim of the study was to formulate VCZ loaded lipid‐based nanoparticles (VCZ‐LNP) by high pressure homogenization (HPH), and the antifungal study confirmed that the optimized VCZ‐ LNP inhibited the fungus reproduction. Expand
Spontaneous and visible light-induced ultraweak photon emission from rat eyes
The results suggest that the photochemical source of retinal discrete noise, as well as retinal phosphenes, may originate from natural bioluminescent photons within the eyes, which are continuously exposed to ambient powerful photons that pass through various parts of the eyes. Expand
