BSA Aggregation in Trehalose-Water Systems

2010

Introduction Recent studies [1] on ternary protein-trehalose-water samples have shown that the protein thermal denaturation temperature is linearly correlated with the glass transition temperature of the system, despite the quite large temperature difference between the two processes. In such studies it is stated that the collective, long range properties of the matrix that regulate the glass transition are strictly correlated with local features on which the denaturation of the protein depends. In order to ascertain whether an analogous correlation exists between the effects of trehalose on the protein’s aggregation process and the glass transition temperature of the system, we performed L…

Aggregation behavior of cationic nanohydrogel particles in human blood serum.

2014

For systemic siRNA delivery applications, well-defined drug carriers are required that guarantee stability for both carrier and cargo. Among various concepts progressing in market or final development, cationic nanohydrogel particles may serve as novel transport media especially designed for siRNA-in vivo experiments. In this work, the interaction of nanohydrogel particles with proteins and serum components was studied via dynamic light scattering in human blood serum as novel screening method prior to applications in vivo. The formation of larger aggregates mostly caused by charge interaction with albumin could be suppressed by nanogel loading with siRNA affording a neutral zeta potential …

GALACTOSE-DECORATED POLYMERIC CARRIERS FOR HEPATOCYTE-SELECTIVE DRUG TARGETING

2015

In this paper, the current available strategies to realize galactose-decorated nanostructured polymeric systems are summarized. These carriers are designed in order to obtain targeted drug delivery to hepatocytes via galactose (GAL) moieties, i.e., for the treatment of viral hepatitis or liver cancer that are the greater causes of global disability and mortality. Usually, the main followed strategy to obtain galactosylated polymeric carriers is to use galactosylated copolymers. The chemical modifications of preformed polymers with sugar-containing reagents is followed for obtaining lactosaminated human albumin, galactosylated phospholipid-polyaminoacid and polylactide (PLA)- polyaminoacid c…

Prognostic value of IL-6 and IL-10 serum levels and immunonutritional assessment in determining postoperative complications after geriatric surgery

2009

The onset of postoperative septic complications has recently been associated to serum levels of interleukin (IL) IL-6 and IL-10. Patients with complications have higher serum levels than patients without complication after surgery. IL-6 has been recognized as early marker of postoperative septic events. Furthermore IL-6 increases with age, expecially if there are associated diseases. It is a sign of functional deterioration of different organs. The disregulation in interleukin production, anesthetic drugs, hemorrhage and transfusions may lead to the onset of postoperative complications. The latter are more frequent in oncologic patients. The aim of our study is to evaluate pre- and postoper…

THE IMPORTANCE OF TIGHT BLOOD PRESSURE CONTROL IN DIABETIC HYPERTENSIVE PATIENTS

Micro-albuminuria in obese subjects: relationship among body fat distribution, blood pressure and left ventricular structure and function.

1998

OBJECTIVE: To evaluate the relationships among micro-albuminuria, blood pressure and measurements of left ventricular structure and function in centrally and peripherally obese subjects compared with members of a lean control group. METHODS: Centrally obese subjects were subdivided according to whether they had levels of micro-albuminuria higher than 30 mg/24 h (micro-albuminuric group) or lower than or equal to 30 mg/24 h (normo-albuminuric group). For all the subjects we measured heart rate, casual mean blood pressure (MBP), 24 h MBP, total cholesterol level, high-density lipoprotein cholesterol, lipoprotein (a) level, fasting immunoreactive insulin level, plasma renin activity, plasma al…

Central obesity and hypertension: Pathophysiologic role of renal haemodynamics and function

1995

OBJECTIVE: To investigate the role of alterations in renal haemodynamics and function and in plasma renin activity on obesity-induced hypertension. DESIGN: Renal haemodynamics and function, salt-regulating hormones and structural cardiac parameters were evaluated in 20 lean normotensives and in 64 obese subjects with central or peripheral fat distribution, 43 of them were normotensives and 21 of them were hypertensives. Obesity and central fat distribution were defined according to sex-specific 85th percentile respectively of Body Mass Index (BMI) and Waist to Hip Ratio (WHR). MEASUREMENTS: Serum immunoreactive insulin (IRI), plasma renin activity (PRA), plasma aldosterone (PA), microalbumi…

Monitoraggio dell’adeguatezza prescrittiva dell’albumina per uso terapeutico presso una realtà ospedaliera della Provincia di Palermo.

2011

Obiettivi La Direzione Sanitaria dell’Ospedale Buccheri La Ferla - Fatebenefratelli, in collaborazione con la Farmacia Ospedaliera, ha analizzato i dati relativi al consumo annuale di albumina, per poter verificare l’appropriatezza delle prescrizioni sulla base delle indicazioni della letteratura scientifica. Metodi A partire dal 2009 è stata elaborata una modulistica standardizzata di richiesta di albumina mirante a razionalizzarne l’uso. In ciascun modulo sono riportati i dati anagrafici, l’albuminemia, la protidemia totale, l’indicazione terapeutica ed il numero di flaconi richiesti per ciascun paziente. Sono stati analizzati i moduli di richiesta relativi agli anni 2009 e 2010. Tutti i …
