This study presents the histopathological evaluation of effectiveness melatonin as a protectant against acute lung injury induced by radiation therapy.Thirty-two Wistar rats were divided into four groups. The in Group 1 received and underwent therapy. 2 no 3 sham 4 Melatonin was administered at dose 100 mg/kg using an intraperitoneal injection. Radiation therapy delivered on Cobalt-60 unit single fraction 18 Gy through anterior portal covering right entirety. euthanasia 6 weeks following...

A new liquid crystalline oligomer OLC was synthesized from its monomer having Schiff-base type mesogenic group MLC via free radical polymerization. The chemical structures of all compounds were confirmed using UV, FTIR, 1 H NMR, 13 C NMR and MS spectroscopy. thermotropic system based on side chain containing long aliphatic branching studied to determine the change in mesophase behaviour groups. combination differantial scanning calorimetry (DSC) polarize optical microscopy (POM) demonstrated...

This study evaluates the use of recursive partitioning analysis (RPA) grouping in an attempt to predict survival probabilities patients with brain metastases from non-small-cell lung cancer (NSCLC).Seventy-two NSCLC treated radiation therapy were included study. Sixty-three male and nine female. Their median age was 57 years their Karnofsky performance status 70. At time metastases, there no evidence intrathoracic disease 27 extrathoracic limited intracranial 42 patients. In accordance RPA...

New liquid crystalline salicylaldimine-based homopolymers PLC1 and PLC2 have been synthesized from their corresponding monomers 5-(10-undecenyloxy)-2-[[(4-(hexyloxy)phenyl)imino]methyl]phenol (LC1 ) 5-(10-undecenyloxy)-2-[[(4-(hexyl)phenyl)imino]methyl]phenol (LC2 via free radical polymerization. The polymers were characterized by 1H-NMR, differential scanning calorimetry (DSC) optical microscopy in polarized light (polarizing microscope). low molecular weights, so are the oligomeric domain....

Abstract The detection of Cu +2 ion chemically is crucial for both the biological and environmental systems. In this study, fluorescent active pyridine‐based diamide thiazole derivative chemosensor N 2 ,N 6 ‐bis(2‐(benzothiazol‐2‐yl)phenyl)pyridine‐2,6‐dicarboxamide ( 3 ) was synthesized characterized successfully. Fluorometric colorimetric properties selectivity sensitivity different metal ions were determined in DMSO/H O (50:50) medium by using fluorescence spectroscopy. exhibited turn on...

Leather is commercially important material apart from being a complex organic structure to protect livings against external factors.Crude leather converted into end product through some processes such as liming, tanning, dyeing, oiling and finishing.However, in this process hazardous toxic chemicals which may pose occupational exposure on workers are used.This study was performed universe that consisted of 10 businesses 235 employees making for the purpose measuring chemical while they...

Occupational health and safety in work life has still alarming statistics around the world. Despite fact that leather business seems being affected by mechanization, human power important role for it. Workers tanning processes frequently encounter physical chemical risks. Therefore, determination of employee consciousness arrangement trainings it are this sector which is included category 'Very risky work'. In our study, population been determined as active firms Usak Mixed-Organized Leather...
