Nasal mucosa offers advantages to deliver drugs to brain via olfactory route thus provides rapid onset of drug action and hence faster therapeutic effect. Therefore, various strategies have been proposed to improve the delivery of different drugs to brain including liposomes, colloidal drug
The interaction of human serum albumin and folic acid was studied using fluorescence spectroscopy, UV absorption and synchronous fluorescence spectroscopy in the pH 7.4 Tris-HCl buffer system at different temperatures. The research shows that these interactions result in the endogenous fluorescence
Magnetic drug delivery system is one of the most important strategies for cancer diagnosis and treatment. In this study, a novel theranostic system was fabricated based on cyclodextrin nanosponge (CDNS) polymer anchored on the surface of Magnetite nanoparticles (Fe3O4/CDNS NPs)
BACKGROUND
By atrophy, the decrease in volume of the cell due to loss of cell substances is intended. When a sufficiently high number of cells is involved, the whole tissue or organ decreases in volume or becomes atrophic. The oropharyngeal mucous membrane can be the site of processes of mainly
Delayed-type hypersensitivity (DTH) responses were suppressed in mice inoculated with bone marrow cells from mice that had been injected with 10(8) colony-forming units (CFU) of live BCG. Upon analysis of this DTH-suppression by the use of a macrophage migration inhibition (MI) assay, the in vitro
The combination of ion mobility mass spectrometry studies and theoretical calculations including docking studies permitted a detailed structural description of noncovalent complexes of folic acid (FA) and native cyclodextrins (α-CD, β-CD, and γ-CD). The mode of noncovalent association depended on
This work presents a very new look at folate targeting and is focused on synthesizing and assessing the biological activity of folic acid-targeted drug delivery materials based on β-cyclodextrin. Both folic acid and β-cyclodextrin have been covalently conjugated to branched polyethylenimine as the
Crohn's disease is a chronic inflammatory bowel disease of unknown cause with unpredictable remissions and exacerbations. Associated nutritional deficiencies include those involving zinc, magnesium, vitamin B12, folic acid, and vitamin D. A group of patients with Crohn's disease underwent detailed
Polymorphisms in genes encoding the enzymes involved in the metabolism of homocysteine, such as methionine synthase (MTR) and methionine synthase reductase (MTRR), play an important function in the metabolism of folic acid and vitamin B12. The present study aimed to evaluate the association of
Assembled between γ-cyclodextrins (CD) and potassium ions, γ-cyclodextrin metal-organic frameworks (CD-MOF) create spatially extended and ordered cage-like structures. Herein, it was demonstrated that folic acid (FA), a model molecule, could be densely packed inside CD-MOF reaching 2:1 FA:CD molar
Epirubicin (Epr) is an effective chemotherapeutic drug; however, the clinical amenability of Epr is limited by its highly toxic interaction with normal cells. This toxicity can be decreased by utilizing nanocarriers and targeted drug delivery systems. This work describes an approach for the delivery
A folic acid sensor was prepared via an electropolymerized molecularly imprinted polymer (E-MIP) film of a bis-terthiophene dendron on a quartz crystal microbalance (QCM). The cyclic voltammetry (CV) electrodeposition of the imprinted polymer film was monitored by electrochemical QCM or E-QCM,
OBJECTIVE
To explore the relationship among the folic acid, vitamin B12 and diabetic nephropathy and to discuss the mechanism of the diabetic microangiopathy.
METHODS
We selected 80 SD rats, and then divided them into 2 groups randomly. Those were the control group and the model groups. During the
BACKGROUND
Paclitaxel (taxol) is a very effective anticancer drug. However, the solution used to enhance the water solubility of paclitaxel, a mixture of polyoxyethylene castor oil (Cremphor EL) and dehydrated ethanol, causes irritation. Our aim is to develop a water-soluble taxol with a high
This work deals with an analysis of the covalent functionalization of a carbon nanotube using polyethylene glycol chains terminated by folic acid fragments. The analysis is focused on theoretical predictions, using molecular dynamics simulations, of the properties of such constructs as pH controlled
