Article type: Short communication Objective(s): To know whether Scurrula atropurpurea is able to modulate total plasma nitrate/nitrite levels, decrease endothelial damage, and increase endothelial progenitor cells (EPCs) in hypertensive rats. Materials and Methods: The rats were divided in 5 groups: control (normotensive) group, Desoxy cortico sterone (DOCA)-salt hypertensive group, and three D...

Article type: Original article Objective(s): In this research, zeolite X and zeolite Y were used as vehicle to prepare intestine targeted oral delivery systems of indomethacin and ibuprofen. Materials and Methods: A soaking procedure was implemented to encapsulate indomethacin or ibuprofen within synthetic zeolites. Gravimetric methods and IR spectra of prepared formulations were used to assess...

which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Objective(s): Based on knowledge from traditional herbal medicine, Ferula assa-foetida (asafoetida) has several therapeutic applications but there is less knowledge about its effect on neurons. Materials and Methods: In order to evaluate neuronal differentiation, neuronal ...

Article type: Original article Objective(s): The utilization of molecular techniques in the epidemiology of tuberculosis have provided an opportunity for using effective markers to trace the transmission of the disease .The purpose of this study was to compare the genetic patterns of Mycobacterium tuberculosis by three methods of RFLP technique. Materials and Methods: In a cross-sectional and p...

Article type: Original article Objective(s): Alzheimer's disease (AD) is the most common age‐related neurodegenerative disorder. One of the hallmarks of AD is an abnormal accumulation of fibril forms of tau protein which is known as a microtubule associated protein. In this regard, inhibition of tau aggregation has been documented to be a potent therapeutic approach in AD and tauopathies. Unfor...

Article type: Original article Objective(s): In the current study, sunscreen and moisturizing properties of solid lipid nanoparticle (SLN)-safranal formulations were evaluated. Materials and Methods: Series of SLN were prepared using glyceryl monostearate, Tween 80 and different amounts of safranal by high shear homogenization, and ultrasound and high-pressure homogenization (HPH) methods. SLN ...

Article type: Original article Objective(s): Calcineurin (CN) is a main phosphatase and a critical regulator of cellular pathways for learning, memory, and plasticity. The FK-506 (tacrolimus), a phosphatase inhibitor, is a fungalderived agent and a common immune suppressant extensively used for tissue transplantation. To further clarify the role of CN in different stages of learning and memory ...

Article type: Original article Objective(s): Occludin is essential for proper assembly of tight junctions (TJs) which regulate paracellular endothelial permeability. Omega-3 polyunsaturated fatty acids (Ω-3 PUFA) protect endothelial barrier function against injury. Materials and Methods: We examined anti-inflammatory effect of Ω-3 PUFA intake (30 mg/kg/day for 10 days) on expression and locatio...

BACKGROUND Students' perceptions of the educational environment are an important construct in assessing and enhancing the quality of medical training programs. Reliable and valid measurement, however, can be problematic - especially as instruments developed and tested in one culture are translated for use in another. MATERIALS AND METHOD This study sought to explore the psychometric propertie...
