Biodegradable nanoparticulate carriers, have important potential applications for administration of therapeutic molecules. Chitosan based nanoparticles have attracted a lot of attention upon their biological properties such as biodegradability, biocom-patibility and bioadhesivity. The aim of the present investigation was to describe the synthesis and characterization of novel biodegradabl...

The interference of phosphate with the estimation of sodium by the zinc uranyl acetate method has been pointed out by several investigators (l-3). Recently the question as to whether the amount of phosphorus present in serum is great enough to influence the sodium values has been raised again. Hald (2) points out the necessity of removing phosphate before sodium is determined, while Consolazio ...

OBJECTIVES To determine if antenatal exposure to betamethasone for the prevention of neonatal respiratory distress syndrome alters psychological functioning and health related quality of life in adulthood. DESIGN Follow-up of the first and largest double blind, placebo controlled, randomised trial of a single course of antenatal betamethasone for the prevention of neonatal respiratory distres...

PURPOSE This study compares the effect of topical diclofenac with that of betamethasone against postoperative increase of intraocular pressure (IOP) after cataract surgery in normal patients, and also investigated the risk factors for postoperative increase of IOP in each group. METHODS Fifty consecutive patients without systemic disease who have bilateral and symmetrical cataracts underwent ...

STUDY OBJECTIVE Standard treatment for girls with labial fusion has included topical estrogen cream, manual separation, or surgery. Side effects may limit the use of topical estrogen. Betamethasone has recently shown efficacy at separating labial fusion. Local irritation and inflammation may be an initiator of labial fusion. No adverse effects of betamethasone treatment have been documented. Lo...

toxoplasmosis is a protozoal infection caused by toxoplasma gondii. toxoplasmosis produce severe damage in patients who are immunosuppresed. in those who are immunosupressed, latent infection can be reactivated resulting in acute disseminating disease. betamethasone is a synthetic glycocorticoid, used as an anti-inflamatory and immunosuppressant in a wide variety of disorders.the aim of this st...

Sodium-Ion Batteries Cathode materials are decisive for the development of sodium-ion batteries (SIBs). In article number 2110108, Xing-Long Wu and co-workers present a high-entropy Na3V2(PO4)2F3-based cathode advanced SIBs. The effect endows this material with lowered Na+ migration barrier enhanced electronic conductivity, which jointly promote charge transport sodium-storage ability in phosph...

1. The transport of sodium by frog skin and the maintenance of normal potassium levels within the cells of the skin are both dependent on metabolism and on a supply of phosphate bond energy. 2. Except for the common requirement of phosphate bond energy, the transfer mechanism for sodium and the mechanism for maintaining intracellular potassium appear to be independent. 3. The xanthines specific...
