Background and Objective: Ferulic acid is a polyphenolic compound derived from some fruit and different cereals. Previous studies have shown that this compound has antioxidant, anti-apoptosis, and differentiation properties in the nervous system. The aim of this study was to evaluate the effect of ferulic acid on the death of oligodendrocytes and demyelination in male C57B6 / J mice in cuprizon...
determination of titanium (iv) in tap water and ore samples with kinetic - spectrophotometric method
a simple, selective and sensitive method for the determination of trace amount of titanium (iv) based on its catalytic effect on methylene blue- ascorbic acid redox reaction has been reported. the reaction was followed spectrophotometrically by measuring the change in absorbance of methylene blue at 665 nm, 5 minutes after the initiation of the reaction. in this study experimental parameters we...
استفاده از روشهای اکسیداسیون پیشرفته بر پایه رادیکالهای سولفات در زمینه تصفیه پسابها اخیرا بسیار مورد توجه قرار گرفته است. واین بخاطر توانایی اکسیداسیون بیشتر رادیکالهای سولفات نسبت به رادیکالهای هیدرواکسیل میباشد.مقدار زیادی از رنگ های آزو تولید شده در طی فرایند رنگزنی از بین میرود و وارد پسابها می شود و این منجر به آلودگی بسیار زیاد در پسابها میگردد.این در حالی است که رنگهای آزو در ...
Aiming to provide a new class of game dynamics with good long-term rationality properties, we derive a second-order inertial system that builds on the widely studied “heavy ball with friction” optimization method. By exploiting a well-known link between the replicator dynamics and the Shahshahani geometry on the space of mixed strategies, the dynamics are stated in a Riemannian geometric framew...
A simple, accurate and fast vortex-assisted dispersive liquid-liquid microextraction procedure has been developed for the extractive spectrophotometric determination of niflumic acid in biological samples. The method is based on the formation of an ion association complex between niflumic acid and methylene blue. The resulting ion-pair was extracted into dichloromethane and its absorbance was m...
A series of new 2-(phenylthio) benzoylaryl hydrazones were synthesized by acid-catalyzed condensation of hydrazide 3 with corresponding aldehydes. The chemical structures of the compounds were elucidated by FT-IR, 1H-NMR and Mass spectra. All newly synthesized compounds were evaluated for their antimycobacterial activities against Mycobacterium tuberculosis H37Rv using the microplate alamar blu...
Here, we present the case of a 62-year-old patient presenting with a three-month history of asymptomatic, flesh-colored, infiltrated plaques on the fronto-occipital scalp (Figure 1). The patient had a history of dyslipidemia and hypertension but reported no changes in medication in the last two years. Serial histopathological examination of the scalp plaques (over a two-year follow-up period) s...
One of the simplest procedures to demonstrate mucinous substances (acid mucopolysaccharides) in routine histological preparations involves the use of Alcian dyes. Methods involving these dyes have largely. replaced the older, more empirical mucicarmine technique arid are faster and less complicated than the colloidal iron method of Hale,1 which suffers from the possibility of false-positive sta...
