in published high performance liquid chromatographic (hplc) methods for analysis of topiramate (tpm) in pharmaceutical dosage forms and raw materials refractive index detector (rid) has been used which is not available in many laboratories and has low sensitivity. we described a new, sensitive and simple hplc method for determination of topiramate in pharmaceutical forms and in-virto dissolutio...

Reverse engineering of program code is the process of constructing a higher level abstraction of an implementation in order to facilitate the understanding of a system that may be in a \legacy" or \geriatric" state. Changing architectures and improvements in programming methods, including formal methods in software development and object-oriented programming , have prompted a need to reverse en...

We show that in metamagnetic shape memory alloys exhibiting a magnetostructural first order phase transition the direct transition from ferromagnetic austenite to nonmagnetic martensite is isothermal. In contrast to the direct transformation, the reverse one nonmagnetic martensite–ferromagnetic austenite is athermal, just as are athermal both direct and reverse martensitic transformations in co...

in this study, caffeic acid (ca) and its three derivatives including 3-caffeoylquinic acid (3-cqa, neochlorogenic acid), 4-caffeoylquinic acid (4-cqa, cryptochlorogenic acid), and 5-caffeoylquinic acid (5-cqa, chlorogenic acid) were identified in bupleurum chinense aerial parts using reverse-phase high-performance liquid chromatography (rp-hplc) with photodiode array (pda) detector, reference c...

A two dimensional-liquid chromatography (2D-LC) based approach was developed for the identification and quantification of histone post translational modifications in conjunction with mass spectrometry analysis. Using a bottom-up strategy, offline 2D-LC was developed using reverse phase chromatography. A porous graphitic carbon stationary phase in the first dimension and a C18 stationary phase i...

with development of technology and science and continuous increase in productivity, product life cycles are shortened and customer demands are more personalized and diversified, which makes companies face with ever changing and unpredictable competitive environment. therefore, rapid response to market competition has become one of the main focuses and the competitive advantages. today, one of t...

Background: Cutaneous reactions like pruritus and erythema are common in warm months of the year in Bushehr Port, Persian Gulf, Iran due to jellyfish envenomation. This study reports isolation of the Chrysaora hysoscella nematocysts and evaluating its pharmacological activities during a bloom in 2013. Methods: The venom of C. hysoscella captured in Jofre area in Bushehr port was analyzed. Th...
