Hydrophobic cavity formed by oligopeptide for doxorubicin delivery based on dendritic poly(L-lysine).

Numai utilizatorii înregistrați pot traduce articole

To deliver anti-cancer drugs to tumors, a hydrophobic cavity was prepared in the dendritic molecule, dendritic poly(L-lysine) of sixth generation (KG6), which was used as a drug carrier. The dendritic molecule was modified with polyethylene glycol (PEG)-linked hydrophobic penta-phenylalanine or

Tissue-implant response following soft tissue implantation of poly-L-lysine coated UHMW-polyethylene into adult male rats.

It is well demonstrated in the literature that polyethylene materials used in orthopedic applications are highly compatible and non-immunogenic with host tissues. However, recent studies in our laboratory have demonstrated the need for further study of these devices in vivo to further elucidate the

The effect of capsule composition on the biocompatibility of alginate-poly-l-lysine capsules.

Numai utilizatorii înregistrați pot traduce articole

The encapsulation of islets of Langerhans in alginate-poly-l-lysine has been proposed as a method for the immunoprotection of transplanted islets. Although several capsule compositions have been reported, there has been no published study concerning the effect of capsule composition on the severity

[Study on cytomedicine of alginate-poly(L) lysine-alginate microencapsulated hybridoma cells].

OBJECTIVE To study the cytomedicine of alginate-poly (L) lysine-alginate (APA) microencapsulated hybridoma cells and their characteristics. METHODS The spleen cells taken from BALB/C mice immunized with purified human IgG1 kappa type were fused with mouse myeloma cells SP2/0. The hybridoma cell

Evanescent wave cavity ring-down spectroscopy as a probe of interfacial adsorption: interaction of Tris(2,2'-bipyridine)ruthenium(II) with silica surfaces and polyelectrolyte films.

Evanescent wave cavity ring-down spectroscopy (EW-CRDS) has been used to study the interaction of the tris(2,2'-bipyridine)ruthenium(II) complex, [Ru(bpy)(3)](2+), at both native silica surfaces and surfaces modified with polyelectrolyte films. Both poly-l-lysine (PLL) and PLL/poly-l-glutamic acid

A supramolecular nanoparticle system based on β-cyclodextrin-conjugated poly-l-lysine and hyaluronic acid for co-delivery of gene and chemotherapy agent targeting hepatocellular carcinoma.

Numai utilizatorii înregistrați pot traduce articole

A novel supramolecular nanoparticle system with core-shell structure was designed based on β-cyclodextrin-conjugated poly-l-lysine (PLCD) and hyaluronic acid for co-delivery of gene and chemotherapy agent targeting hepatocellular carcinoma (HCC). PLCD was synthesized by the conjugation of

Method for time-resolved monitoring of a solid state biological film using photothermal infrared nanoscopy on the example of poly-L-lysine.

We report time-resolved photothermal infrared nanoscopy measurements across a spectral range of more than 100 cm(-1) (1565 cm(-1) to 1729 cm(-1)) at nanoscale spatial resolution. This is achieved through a custom-built system using broadly tunable external cavity quantum cascade lasers in

Poly-L-lysine functionalized large pore cubic mesostructured silica nanoparticles as biocompatible carriers for gene delivery.

Numai utilizatorii înregistrați pot traduce articole

Large pore mesoporous silica nanoparticles (LP-MSNs) functionalized with poly-L-lysine (PLL) were designed as a new carrier material for gene delivery applications. The synthesized LP-MSNs are 100-200 nm in diameter and are composed of cage-like pores organized in a cubic mesostructure. The size of

Scardovia wiggsiae sp. nov., isolated from the human oral cavity and clinical material, and emended descriptions of the genus Scardovia and Scardovia inopinata.

Six strains of anaerobic, pleomorphic Gram-positive bacilli, isolated from the human oral cavity and an infected arm wound, were subjected to a comprehensive range of phenotypic and genotypic tests and were found to comprise a homogeneous group. 16S rRNA gene sequence analysis revealed that the

Molecular dynamics simulation of coarse-grained poly(L-lysine) dendrimers.

Numai utilizatorii înregistrați pot traduce articole

Poly(L-lysine) (PLL) dendrimer are amino acid based macromolecules and can be used as drug delivery agents. Their branched structure allows them to be functionalized by various groups to encapsulate drug agents into their structure. In this work, at first, an attempt was made on all-atom simulation

Biocompatibility and immune acceptance of adult porcine islets transplanted intraperitoneally in diabetic NOD mice in calcium alginate poly-L-lysine microcapsules versus barium alginate microcapsules without poly-L-lysine.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND If alginate microcapsules are to be used clinically for therapeutic cell transplants, capsule formulations must be designed to enhance optimal biocompatibility and immune acceptance. METHODS Microcapsules were generated using highly purified, endotoxin-free, ultra-low viscosity, high

Study of the influence of both cyclodextrins and L-lysine on the aqueous solubility of nimesulide; isolation and characterization of nimesulide-L-lysine-cyclodextrin complexes.

Numai utilizatorii înregistrați pot traduce articole

Nimesulide is a nonsteroidal antiinflammatory drug that exhibits a very poor water solubility (0.01 mg.mL-1). A nimesulide-beta-cyclodextrin complex prepared according to patent application WO 94/ 02177 has an aqueous solubility of approximately 16 mg.mL-1 of nimesulide. A nimesulide-L-lysine salt

External cavity-quantum cascade laser infrared spectroscopy for secondary structure analysis of proteins at low concentrations.

Numai utilizatorii înregistrați pot traduce articole

Fourier transform infrared (FTIR) and circular dichroism (CD) spectroscopy are analytical techniques employed for the analysis of protein secondary structure. The use of CD spectroscopy is limited to low protein concentrations (<2 mg ml(-1)), while FTIR spectroscopy is commonly used in a higher

Intraperitoneal photoimmunotherapy of ovarian carcinoma xenografts in nude mice using charged photoimmunoconjugates.

OBJECTIVE The objective of this study was to compare the efficacy of photoimmunoconjugates with cationic and anionic molecular charges on intraperitoneal photoimmunotherapy of ovarian cancer xenografts in nude mice. METHODS The photosensitizer chlorin(e6) (c(e6)) was conjugated via a poly-l-lysine

Protein aging by carboxymethylation of lysines generates sites for divalent metal and redox active copper binding: relevance to diseases of glycoxidative stress.

Numai utilizatorii înregistrați pot traduce articole

Aging and age-related diseases are associated with the production of reactive oxygen species which modify lipids, proteins and DNA. Here we hypothesized the glyco- and lipoxidation product N(epsilon)-(carboxymethyl)lysine (CML) in proteins should bind divalent and redox active transition metal
