PRODUCTION OF POLYANILINE COMPOSITE CONTAINING Fe2O3 AND CoO WITH NANOMETER SIZE USING HYDROXYPROPYLCELLULOSE AS A SURFACTANT

In this study, composite of polyaniline containing Fe2O3 and CoO with nanometer size was synthesized by a chemical method using hydroxyl-propylcellulose as a surfactant. The characteristics of products such as morphology and conductivity were studied. The results indicate that, the morphology and conductivity of product are dependent on the surfactant, the type and concentration of metallic oxide

THE THEORY OF CONSTRAINTS: A COMPARATIVE ASSESSMENT

ABSTRACT This paper examines in detail the relative utility of the Theory of Constraints compared to traditional management accounting approaches to resource utilisation in aiding decisionmaking. It also considers the propagation and evolution of the Theory of Constraints and critically examines the response it has generated in the accounting and management literature. The continuing survival of cost accounting in the face of frequent assaults similar to Goldratt's may in part be due to the ability of the discipline to adapt its practices to integrate the mandated improvements into practice and educational curricula. One example is the Theory of Constraints itself an

Effectiveness of the Intraperitoneal Irrigation using Sodium Bicarbonate on Postoperative Pain Severity after Midline Laparotomy

Background and Objectives: Sodium bicarbonate may be effective in reducing the pain since it creates an alkaloid environment and prevents acidosis. Therefore, this study aimed to investigate the effect of intraperitoneal irrigation using sodium bicarbonate on postoperative pain severity.   Methods: This non-randomized, double-blind clinical trial was performed on 50 candidates for elective surgery with midline laparotomy at Besat Hospital in Hamadan, Iran, during 2017-18. The patients were assigned into an intervention (underwent intraperitoneal irrigation using sodium bicarbonate solution) and a control group (underwent intraperitoneal irrigation using the normal saline solution). The severity of the pain 12 and 24 h after the surgery in patients was measured using a Visual Analog Scale (VAS).   Results: The mean ages of the patients were 48.87±11.68 and 49.56±15.44 years in the intervention and control groups, respectively. Regarding gender distribution, 52% of the participants were male. Moreover, the mean pain scores 12 h after the surgery were 6±1.71 and 7.56±1.47 in the intervention and control groups, respectively. Additionally, the mean pain scores obtained from VAS 24h after the surgery were 20.20±1.15 and 3.68±1.62 in the intervention and control groups, respectively. According to the results, the mean score of pain was significantly lower in the intervention group, compared to the control group (P<0.05). However, there was no significant difference between the two groups regarding the frequency of complications and the amount of opioid consumption.   Conclusion: The combination of sodium bicarbonate and normal saline solution for intraperitoneal irrigation is a simple method with no complication. This can help reduce postoperative pain up to 24 h after surgery

ANRIL Genetic Variants in Iranian Breast Cancer Patients

Objective The genetic variants of the long non-coding RNA ANRIL (an antisense noncoding RNA in the INK4 locus) as well as its expression have been shown to be associated with several human diseases including cancers. The aim of this study was to examine the association of ANRIL variants with breast cancer susceptibility in Iranian patients. Materials and Methods In this case-control study, we genotyped rs1333045, rs4977574, rs1333048 and rs10757278 single nucleotide polymorphisms (SNPs) in 122 breast can- cer patients as well as in 200 normal age-matched subjects by tetra-primer amplification refractory mutation system polymerase chain reaction (T-ARMS-PCR). Results The TT genotype at rs1333045 was significantly over-represented among pa- tients (P=0.038) but did not remain significant after multiple-testing correction. In addi- tion, among all observed haplotypes (with SNP order of rs1333045, rs1333048 rs4977574 and rs10757278), four haplotypes were shown to be associated with breast cancer risk. However, after multiple testing corrections, TCGA was the only haplotype which remained significant. Conclusion These results suggest that breast cancer risk is significantly associated with ANRIL variants. Future work analyzing the expression of different associated ANRIL haplotypes would further shed light on the role of ANRIL in this disease
