The conversion of citrulline to arginine in kidney [PDF]

open access: yes, 1941
Glycocyamine is formed in the kidney by the transfer of the amidine group of arginine to the nitrogen atom of glycine. In the study of this reaction it was observed that glycocyamine was also formed from citrulline and glycine.

Strategies to Improve the Lipophilicity of Hydrophilic Macromolecular Drugs

open access: yesAdvanced Healthcare Materials, EarlyView.
Hydrophilic macromolecular drugs can be successfully lipidized by covalent attachment of lipids, by hydrophobic ion pairing with negatively or positively charged surfactants, and by dry or wet reverse micelle formation. Lipophilicity enhancement of hydrophilic macromolecules has several benefits including stability and bioavailability improvement ...

Free amino acids in a cave beetle \u3cem\u3eDarlingtonea kentuckensis\u3c/em\u3e Valentine (Coleoptera: Carabidae) [PDF]

open access: yes, 1974
Free amino acids of Darlingtonea kentuckensis were investigated by two-dimensional, thin-layer chromatography on Silica Gel G. Thirteen amino acids which could be identifìed (alanine, glutamic acid, glycine, histidine, isoleucine and/or leucine, lysine ...

Conformational studies of various hemoglobins by natural-abundance 13C NMR spectroscopy [PDF]

open access: yes, 1972
Studies of variously liganded hemoglobins (both from human and rabbit) by natural-abundance 13C NMR spectroscopy have revealed apparent conformational differences that have been interpreted on the basis of two quaternary structures for the α2ß2 tetramer,

Self‐Assembling Peptide Hydrogels Support Stromal Vascular Fraction Viability to Promote In Vivo Nerve Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Stromal vascular fraction (SVF) may enhance nerve repair, especially when delivered in a self‐assembling peptide hydrogel (SAPH). In vitro, softer SAPH increased neuronal explant outgrowth and supported greater SVF viability and proliferation. In a rat sciatic defect, SVF in an optimized SAPH produced motor and sensory recovery equivalent to autograft ...

Ostracode-based aminostratigraphy and aminochronology of a tufa system in central Spain [PDF]

open access: yes, 2005
In the Priego area, central Spain, extensive tufa deposits are located in three small tributaries located at the head of the 1000 kmlong Tagus River. The deposits are originated after karst-origin running waters emerged from the confines of the canyons ...

Delivery of Multifunctional Microspheres via Intravesical Instillation for Bladder Carcinoma: Therapeutic Potential and Mechanistic Insights

open access: yesAdvanced Healthcare Materials, EarlyView.
PCTM microspheres were successfully synthesized using microfluidic and click chemistry techniques.In Vivo and in vitro experiments have shown that PCTM microspheres have obvious targeting, adhesion, membrane penetration and anti‐tumor properties for bladder tumors.The antitumor mechanism of PCTM microspheres is to indirectly induce S‐stage blockage of ...

Equilibrium of the solubility isotherm in systems Cobalt(II) chloride-glutamic acid-water [PDF]

open access: yesE3S Web of Conferences
The study is focused on the interaction between glutamic acid and hexavodic cobalt chloride. The solubility curve, influenced by the high solubility of the initial components, extends horizontally along a catheter corresponding to the cobalt chloride ...

An NMR-based metabolomic approach to investigate the effects of supplementation with glutamic acid in piglets challenged with deoxynivalenol. [PDF]

open access: yesPLoS ONE, 2014
Deoxynivalenol (DON) has various toxicological effects in humans and pigs that result from the ingestion of contaminated cereal products. This study was conducted to investigate the protective effects of dietary supplementation with glutamic acid on ...
