Skeletal muscle: a significant novel neurohypophyseal hormone-secreting organ [PDF]
Vasopressin (arg8-vasopressin) and oxytocin are closely relalated hormones, synthesized as pre-hormones in the magnocellular neurons of the paraventricular Q6 and supraoptic nuclei of the hypothalamus.

Arginine-rich peptides destabilize the plasma membrane, consistent with a pore formation translocation mechanism of cell penetrating peptides [PDF]
Recent molecular dynamics simulations (Herce and Garcia, PNAS, 104: 20805 (2007)) have suggested that the arginine-rich HIV Tat peptides might be able to translocate by destabilizing and inducing transient pores in phospholipid bilayers. In this pathway for peptide translocation, arginine residues play a fundamental role not only in the binding of the ...

Arginine, due to the guanidine moiety, increases peptides’ hydrophilicity and enables interactions with charged molecules, but at the same time, its presence in a peptide chain might reduce its permeability through biological membranes.

Comparative Density Functional Theory and Density Functional Tight Binding Study of Arginine and Arginine-Rich Cell-Penetrating Peptide TAT Adsorption on Anatase TiO2 [PDF]
We present a comparative Density Functional Theory (DFT) and Density Functional Tight Binding (DFTB) study of geometries and electronic structures of arginine (Arg), arginine adsorbed on the anatase (101) surface of titania in several adsorption configurations, and of an arginine-rich cell penetrating peptide TAT and its adsorption on the surface of ...

Hyaluronan-Arginine Enhanced Interaction Emerges from Distinctive Molecular Signature with Improved Electrostatics and Side-Chain Specificity [PDF]
Hyaluronan, a sugar polymer found outside the plasma membrane, is a critical component of the extracellular matrix (ECM) scaffold. Hyaluronan's length and moderate negative charge aid in ECM entanglement and solubility. This allows it to effectively foster gel-like conditions, which are critical for supporting and protecting cells in various tissues ...

Serum Sodium Concentration During Arginine Vasopressin Infusion in Critically Ill Children
Background: Intravenous arginine vasopressin is increasingly used for the treatment of critically ill children. It bears the risk of hyponatraemia with potential severe long-term sequelae, but data on hyponatraemia as a side effect of continuous ...

A three-year-old boy with hypodipsic hypernatremia syndrome
We describe a three-year-old boy who had a growth and psychomotor retardation associated with inappropriate lack of thirst and vasopressin secretion in the presence of chronic plasma hyperosmolarity.

Fabrication and properties of L-arginine-doped PCL electrospun composite scaffolds [PDF]
The article describes fabrication and properties of composite fibrous scaffolds obtained by electrospinning of the solution of poly({\epsilon}-caprolactone) and arginine in common solvent. The influence of arginine content on structure, mechanical, surface and biological properties of the scaffolds was investigated.
