The modified Wilson model and predicting drug solubility in water-cosolvent mixtures
Applicability of the modified Wilson model for calculating drug solubility in water-cosolvent mixtures is presented. The accuracy and predictability of the model are compared with those of other models which calculate ...
Chameleonic effect and some models for predicting drug solubility in solvent mixtures
A new model derived from an excess free energy approach which expresses drug solubility in solvent mixtures showing multiple solubility peaks, the chameleonic effect, with respect to the concentrations of solvents in a ...
"We noticed that suddenly the country has become full of MRI". Policy makers' views on diffusion and use of health technologies in Iran
Objective: Uncontrolled proliferation of health technologies (HT) is one contributor to the increasing pressure on health systems to adopt new technologies. With limited resources, policy-makers encounter difficulties in ...
"Floating Meniscus" a specific indicator of Anterior Cruciate Ligament rupture
Although Magnetic Resonance (MR) imaging is accurate in diagnosis Anterior Cruciate Ligament (ACL) rupture, in many cases using indirect signs are inevitable for appropriate decision-making. This study aimed to investigate ...
"Numb chin" as the first and sole presenting sign of multiple sclerosis
Cranial nerve palsies are occasional clinical findings in multiple sclerosis. Sometimes, they are the presenting sign of multiple sclerosis. Facial numbness localized in the region of the distribution of the mental nerve ...
β-Hematin formation assay for screening of potential antimalarial activity of the extracts and fractions of three Artemisia species
In this study, In-vitro ?-hematin formation assay, a spectrophotometric assessment is used to screen potential antimalarial effects of Artemisia extracts as well as their fractions. The n-hexane (n-hex), dichloromethane ...
[99mTc-DMSA (V)] in detection of metastases of medullary thyroid carcinoma
Introduction: Medullary thyroid carcinoma (MTC) is a rare thyroid cancer secreting calcitonin (CT) which is the most sensitive and specific tumor marker for MTC. This type of thyroid cancer is able to metastasize to different ...

5-HT 1A receptor activation improves anti-cataleptic effects of levodopa in 6-hydroxydopamine-lesioned rats
Background and the purpose of the study: In Parkinsons disease (PD) prolong use of L-DOPA causes some motor disorders such as wearing-off and L-DOPA induced dyskinesia (LID). In this investigation the effect of 8-OHDAPT, ...
3D curvelet-based segmentation & quantification of drusen in optical coherence tomography images
Spectral-Domain Optical Coherence Tomography (SD-OCT) is a widely used interferometric diagnostic technique in ophthalmology that provides novel in vivo information of depth-resolved inner and outer retinal structures. ...
