Azo dyes are widely used in textile, printing, cosmetic, drug and food-processing industries. They are also used extensively in laboratories as either biological stains or pH indicators. The extent of such use is related to the degree of industrialization. Since intestinal cancer is more common in highly industrialized countries, a possible connection may exist between the increase in the numbe...

The photodegradation of Ponceau-S dye was investigated using UV radiation in presence of nanosized Fe2 O3 .Removal efficiency of Ponceau-S was sensitive to the operational parameters such as dye concentration, catalyst dose, pH, contact time, TOC and COD. The photocatalytic treatment of red colored Ponceau-S dye by magnetic nano semiconductor (Fe2 O3 )is an effective, economic and faster mode. ...

In this work, optical retardation (OR) was investigated in corneal stroma collagen fibers from nonobese diabetic (NOD) and healthy (BALB/c) mice. Linear dichroism (LD) was investigated in corneas stained with Ponceau SS and Toluidine Blue, using microspectrophotometer. NOD corneas showed higher OR values than the control. Ponceau SS-complexed collagen fibers showed positive LD that was higher f...

Neurological diseases are among the most common in Ukraine, especially given development of technology food industry and accelerated pace life, which contributes to an increased number additives nutrition products. The cerebellum is easily affected by adverse effects. Our research aimed conduct a comparative analysis immunomorphological changes astrocytes with neurons cerebellar gray matter rat...

The interleukin-4 receptor (IL-4R) is expressed as a 140-Kd membrane glycoprotein that binds IL-4 with high affinity. Recently, cDNA clones for the murine IL-4R have been isolated. One clone encodes an integral membrane protein, while another encodes a protein in which translation is terminated before the transmembrane region, thus producing a soluble form of the IL-4R (sIL-4R). HeLa cell clone...

Tau is a microtubule-binding protein expressed in neurons and the equal ratio between 4-repeat (4R) 3-repeat (3R) isoforms are maintained normal adult brain function. Dysregulation of 3R;4R causes tauopathy human that recapitulate tau health disease will provide platform for elucidating pathogenic processes involving pathology. We carried out extensive characterizations derived by microRNA-indu...

The murine interleukin 4 receptor (IL-4R) exists as a transmembrane protein transducing pleiotropic IL-4 functions, or as soluble (s)IL-4-binding molecule with potent immunoregulatory effects. In this study we identified and characterized a murine IL-4R allotype. Sequence analysis of the IL-4R cDNA of BALB/c mice revealed 18 base substitutions leading to three extracellular and five cytoplasmic...

Abstract This study aimed to create CTAB-modified bentonite organoclay (Bt@CTAB) by mixing the naturally occurring mineral (Bt) with cationic surfactant cetyltrimethylammonium bromide (CTAB). Elemental analysis, N 2 adsorption–desorption isotherm, scanning electron microscopy (SEM), FTIR spectroscopy, XRD, and thermogravimetric (TGA) analysis have been employed analyze both unmodified Bt Bt@CTA...

Pathological evidence for selective four-repeat (4R) tau deposition in certain dementias and exon 10-positioned MAPT mutations together suggest a 4R-specific role in causing disease. However, direct assessments of 4R toxicity have not yet been accomplished in vivo. Increasing 4R-tau expression without change to total tau in human tau-expressing mice induced more severe seizures and nesting beha...

Tauopathies are defined by assembly of the microtubule associated protein tau into filamentous tangles and classified by the predominant tau isoform within these aggregates. The major isoforms are determined by alternative mRNA splicing of exon 10 generating tau with three (3R) or four (4R) approximately 32 amino acid imperfect repeats in the microtubule binding domain. In normal adult brains t...
