Synthesis of recombinant atrial natriuretic peptide (rANP) using hybrid fusion protein-phage fr coat/ANP (CP/ANP).
1997
Abstract Baumanis, V., I. Jansone, A. Skangals, I. Mandrika and V. Berzins. Synthesis of recombinant atrial natriuretic peptide (rANP) using hybrid fusion protein-phage fr coat/ANP (CP/ANP). Peptides 18(8) 1229–1235, 1997.—Recombinant atrial natriuretic peptide (rANP) was expressed in and isolated from E. coli. rANP was purified using HPLC. Amino acid analysis, partial sequencing, and molecular mass were determined. Fused protein was used to rise polyclonal antibodies and to develop of immunoenzymatic assays of rANP and CP/ANP. Experiments were designed to study rANP effects on isolated rabbit aortic strips and to examine hypotensive, diuretic, and natriuretic activity, as well as renal cre…

RELATIONSHIPS OF SERUM URIC ACID WITH PLASMA RENIN ACTIVITY AND PLASMA ALDOSTERONE IN UNTREATED HYPERTENSIVE SUBJECTS
2013
In experimental studies conducted in rats, raising serum uric acid (SUA) levels resulted in stimulation of intrarenal renin expression. Studies in humans exploring the association of SUA with plasma renin activity (PRA) yielded conflicting results. Moreover, little is known about the relationship between plasma aldosterone concentration (PAC) and SUA. The aim of our study was to analyse the relationships between SUA, PRA and PAC and the influence of age and gender on these relationships in a group of subjects with primary hypertension. We enrolled 281 patients (men 59%), with untreated primary hypertension and normal renal function. The study population wad divided in two subgroups on the b…
FOKI AND BSMI VITAMIN D RECEPTOR GENE POLYMORPHISMS, PLASMA RENIN ACTIVITY AND ESSENTIAL ARTERIAL HYPERTENSION
2015
Objective: Our aims were to analyze the relationship between 25hydroxyvitamin D(25[OH]D) plasma levels and clinical and ambulatory blood pressure (BP) values, and to identify any possible association between hypertension and FokI and BsmI vitamin D receptor (VDR) gene polymorphisms in essential hypertensive patients. Design and method: Seventyone essential hypertensive patients and seventytwo controls, 18–75 years old, were enrolled. Clinical physical examination, routine blood chemistry, clinical BP, 24 hour ambulatory blood pressure monitoring, 25[OH]D and Plasma Renin Activity (PRA) assay, and FokI and BsmI VDR polymorphisms analysis were obtained. Results:We observed a significant negat…
Polimorfismo I/D del gene ACE: possibile biomarcatore genetico della patologia ipertensiva

Polimorfismo del gene ACE:gene della longevità o fattore di rischio nella patologia ipertensiva
2012
Negli ultimi decenni l’allungamento della vita media ha stimolato un particolare interesse nello studio dei processi dell’invecchiamento e nella ricerca di possibili geni coinvolti nella longevità. In particolare i centenari dimostrano di avere una prevalenza minore di malattie cardiovascolari e dei fattori di rischio ad essa correlati. L’enzima di conversione dell’angiotensina (ACE), presente in tutte le cellule endoteliali, gioca un ruolo essenziale nel mantenimento dell’omeostasi del flusso vascolare, regolando sia la produzione del vasocostrittore angiotensina II sia inattivando la bradichinina. In particolare alcuni studi hanno riportato una possibile correlazione tra il polimorfismo I…
Biotin-Containing Reduced Graphene Oxide-Based Nanosystem as a Multieffect Anticancer Agent: Combining Hyperthermia with Targeted Chemotherapy
2015
Among the relevant properties of graphene derivatives, their ability of acting as an energy-converting device so as to produce heat (i.e., thermoablation and hyperthermia) was more recently taken into account for the treatment of solid tumors. In this pioneering study, for the first time, the in vitro RGO-induced hyperthermia was assessed and combined with the stimuli-sensitive anticancer effect of a biotinylated inulin-doxorubicin conjugate (CJ-PEGBT), hence, getting to a nanosystem endowed with synergic anticancer effects and high specificity. CJ-PEGBT was synthesized by linking pentynoic acid and citraconic acid to inulin. The citraconylamide pendants, used as pH reversible spacer, were …
