objective(s) the role of therapeutic drug monitoring (tdm) in patient care has grown rapidly since its introduction three decades ago. the aim of present study was to evaluate the possible relationship between serum levels and the clinical response of valproic acid (vpa). materials and methods in the present study we evaluated a homogeneous group of adult patients receiving vpa monotherapy. a t...

this study investigated the feasibility of using different extracting solutions at various concentrations to remove copper from low permeability silty loam soils, which have a high buffering soil, ph of 7.6, where it spiked with copper at concentration of about 1500 mg/kg to represent soil conditions. the most efficient extracting solutions could be used as purging/extracting solutions in other...

objective: newbouldia laevis seem, is an ubiquitous perennial plant belonging to the family bignoniaceae with varying applicability in ethnomedicine. methods: the anticonvulsant effect of the aqueous extracts of root and stem bark preparations was undertaken using standard techniques. results: results showed that the ld50 in mice was 489.8mg/kg body weight while 5.6mg/kg body weight protected m...

background and purpose: self-medication is a global medical issue, the rate of which has been reported to be on the rise in recent years. this study aimed to evaluate the prevalence rate of self-medication and the associated factors among the university students of ahvaz city, iran. materials and methods: this cross-sectional study was conducted at jundishapur and shahid chamran universities of...

in present study, molecular dynamics simulation of cadmium (ii), lead (ii) and copper (ii) removal from aqueous electrolyte solutions using the ion-exchange process with the zeolite particles was done. the results showed that, most of the particles had the highest affinity of ion exchanging with lead (ii) and the lowest affinity with copper (ii). the calculated mean ion-exchange ratios showed t...

Electret ion chambers are inexpensive, light-weight, commercially available, passive charge-integrating devices for accurate measurement of different radiations. Performance of electret ion chambers for surface alpha contamination measurement was evaluated. Ion chambers of two types and electrets of three thicknesses were used for the study. Calibration of the electret ion chambers was performe...

To study the effects of heavy-ion radiosurgery on the hemopoietic function of a silkworm, hemopoietic organs of larvae were locally irradiated with carbon-ion beams, and the changes in the hemocyte density and in the hemocyte function were investigated. When the larvae were irradiated by 50 Gy to 300 Gy carbon ions on the 3rd day of the 4th instar, the hemocyte densities did not change for a wh...

A reversible photo-driven sensor for aluminum ions based on photochromicspiropyran was reported with rapid response time. The detection of aluminum wasperformed via the chelation of aluminum ions with the merocyanine form (MC) ofphotochromic spiropyran. ¹H NMR studies confirmed the conversation from the MC forminto the Al3+ -MC form. Addition of aluminum ions to the spiropyran (SP) in a MeCN/H₂...

A number of studies have suggested that the irradiation behavior and damage processes occurring during sequential and simultaneous particle irradiations can significantly differ. Currently, there is no definite answer as to why and when such differences are seen. Additionally, the conventional multi-particle irradiation facilities cannot correctly reproduce the complex irradiation scenarios exp...
