Microencapsulation has become a common technique in the production of controlled release dosage forms. Many results have been reported, concerning the use of alginate beads as controlled release drug formulations. Alginate has a unique gel-forming property in the presence of multivalent cations, in an aqueous medium. Ibuprofen is an excellent analgesic and antipyretic, non-steroidal anti-inflam...

Objective(s): Acute lung injury (ALI) has a high mortality rate and is characterized by damage to pulmonary system giving rise to symptoms such as histological alteration, lung tissue edema and production of proinflammatory cytokine. p-Coumaric acid (p-CA), as a phenolic compound, that is found in many types of fruits and vegetables has been reported to exhibit a thera...

Background: Dental caries is one of the most common oral diseases in pre-school children. Several factors can affect caries process. Aim of this study was comparison of some of the chemical properties of saliva such as total antioxidant capacity, total protein, pH, nitric oxide level in caries free (CF), and caries active (CA) children.<...

The present study was conducted to clarify the effect of hyperosmolar solutions on the constrictor responses of cerebral arteries to vasoactive agents, in vitro. The canine basilar arteries under resting tension were slightly relaxed with both mannitol (0.5, 1 and 2%) and sucrose (1, 2, and 4%). Constrictor responses of canine basilar arteries to 40 mM K+, 10(-7) M serotonin or 10(-6) M prostag...

This study investigates the effect of sub-phonemic variation in bilabial stop and sibilant fricative consonants on word identification. Recent research suggests that sub-phonemic variation in stop voicing contrasts influences lexical processing. The present study seeks further support for this view by examining listeners’ responses to synthetic speech varying along VOT and fricative place conti...

Background—Ca overload plays an important role in the pathogenesis of cardioplegic ischemia-reperfusion injury. The standard technique to control Ca overload has been to reduce Ca in the cardioplegic solution (CP). Recent reports suggest that Na/H exchange inhibitors can also prevent Ca overload. We compared 4 crystalloid CPs that might minimize Ca overload in comparison with standard Mg-contai...

Multilingual generation is becoming an increasingly important aspect of implemented systems that showcase the abilities of generation systems. Most such systems require multiple grammars, one for each language which must be deployed. Yet little is known about the development costs for additional languages which are developed not from scratch, but by adapting existing resources. We ported a stan...

aim : this study evaluated the results and efficacy of serum ca 19-9 in determining the nature of a pancreatic solid mass in patients referred for investigation of possible malignancy. background : a wide variety of tumor markers have been proposed for pancreatic cancer but currently the only one with any practical usefulness for diagnosis, prognosis, and monitoring of treatment is “ca 19-9 ”. ...

Within this paper we study the Minkowski sum of prisms (" Cephoids ") in a finite dimensional vector space. For a vector a ∈ R n with positive components we write ¯ a = (1 ¯ a 1 1 ¯ an) and denote by = ¯ a = {x ∈ R n || ¯ a, x 1 , x 0} the associated prism. We provide a representation of a finite sum of prisms in terms of inequalities.

Let SH denote the homothety class generated by a convex set S ⊂ R: SH = {a + λS | a ∈ R, λ > 0}. We determine conditions for the Minkowski sum BH + CH or the Minkowski difference BH ∼ CH of homothety classes BH and CH generated by closed convex sets B,C ⊂ R to lie in a homothety class generated by a closed convex set (more generally, in the union of countably many homothety classes generated by...
