مقدمه: به منظور بهبود دقت تشخیص پوسیدگی نباید از روش های تهاجمی استفاده گردد و استفاده از رنگ کننده پوسیدگی بیشتر توصیه می شود. همچنین می توان از محلول های ضد باکتری رنگ کننده به عنوان روش بیولوژیک در تشخیص پوسیدگی استفاده کرد. هدف از این مطالعه تشخیص عاج سالم از عاج عفونی بوسیله دو محلول رنگامیزی پویدان ایوداین واسید رد می باشد. روش بررسی: در این بررسی تجربی، 140 عدد دندان مولر پوسیده جمع آوری...
background and purpose:organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. the aim was to evaluate the performance nanoscalezero-valent iron (nzvi) in the removal of dye acid red 18 (ar18) from aqueous solutions. materia...
microRNAs regulate the development of myogenic progenitors, and the formation of skeletal muscle fibers. However, the role miRNAs play in controlling the growth and adaptation of post-mitotic musculature is less clear. Here, we show that inhibition of the established pro-myogenic regulator miR-206 can promote hypertrophy and increased protein synthesis in post-mitotic cells of the myogenic line...
the photocatalytic degradation of two anionic azo dyes acid red88 (ar 88) and acid orange 7 (ao7) was investigated in aqueous solution using a tio2-containing hydrogel and uv light. the ph-sensitive hydrogel poly (styrene-alt-maleic anhydride) (psma), was synthesized and crosslinked in the presence of melamine and tio2 nanoparticles which results in entrapment of tio 2 into the melamine-grafted...
مقدمه: صنایع نساجی و رنگرزی یکی از مهمترین صنایع هر کشوری محسوب میگردند. در این گونه صنایع به دلیل استفاده از انواع رنگها در فرآیندهای مختلف، فاضلاب حاصل نیز به شدت رنگی بوده و میبایست قبل از تخلیه به محیطزیست تصفیه گردد. لذا هدف از این تحقیق بررسی کارایی نانوذرات آلومینا در حذف رنگ Acid Red 18 از محیطهای آبی است. روش بررسی: این تحقیق در مقیاس آزمایشگاهی انجام شد. در این آزمایش یک محلول سن...
The photodissociation dynamics of formic acid (HCOOH) at 206 nm have been investigated from rotationally resolved laser induced fluorescence spectra of OH (Π) fragments produced exclusively in the ground state. From the spectra, the rotational energy of the fragments was measured to be 820 ± 50 cm−1. The translational energy released in the products, which is 87% of the total available energy o...
The pH dependence study reveals that the Cys 206 sulphydryl group of bovine carbonicanhydrase in the native form is not exposed. During the reaction of 2,2'-dithiobispyridine (2-DTP) with the enzyme, there was no absorbance change recorded. In the presence ofsurfactants, the pH dependence profiles of the apparent second order rate constants, kapp, forthe reaction of 2-DTP with bovine carbonic a...
Ninety-one strains of Pseudomonas pseudomallei were tested in the API 20E system and in equivalent conventional tests. Except for utilisation of citrate there was good correlation between API and conventional tests. Seven-digit profiles were constructed from each strain after 48 hours' incubation, and numerical codes 2 006 727, 2 206 706, 2 206 707, and 2 206 727 accounted for 77% of strains te...
Background: Apple is the most consumed fruit in many countries of the world and has very important role in individual's diet and health. The aim of this study was to determine the vitamin C (Ascorbic acid), organic acids (citric acid and malic acid), and phenolic compounds concentrations of apple cultivars grown in Khorramabad and Boroujerd cities. Materials and Methods: At this cross-sectiona...
