N-Propylsulfamic acid supported onto magnetic Fe3O4 nanoparticles (MNPs-PSA) was used as an efficient and magnetically recoverable catalyst for synthesis of 2H-Indazolo[2,1-b]phthalazine-1,6,11(13H)-trione derivatives from the three-component, one-pot condensation reaction of phthalhydrazide, aromatic aldehydes and cyclic 1,3-diones, in good to excellent yields at 100 °C under solvent-free conditions. The catalyst was easily separated with the assistance of an external magnetic field from the reaction mixture and reused for several consecutive runs without significant loss of its catalytic efficiency. In order to compare, the synthesis of 2HIndazolo[ 2,1-b]phthalazine-1,6,11(13H)-trione derivatives in the presence of catalytic amount of sulfamic acid (SA) under same reaction condition was also reported.

Phenolic compounds are present in different concentrations in the effluent from numerous industrial andagricultural activities. These compounds are harmful to living organisms due to their high toxicity, hence indicating aserious environmental concern. Although conventional methods such as chemical, physical, and physicochemical procedureshave been widely used for treating phenol-contaminated wastewaters, they are not useful owing to some shortcomings. Compared to conventional procedures, much attention has been recently devoted to enzymatic methodsbecause of high catalytic efficiency, mild operating conditions and environmentally friendly feature. Among variousenzymes, laccases have demonstrated a superior potential for removing phenolic contaminants. Thus, this review summarizesthe up-to-date literature on the use of free and immobilized laccases from different microbial source in thedegradation and remediation of phenolic pollutants in batch processes and continuous reactors. In general, examplesthrough the review approve that free laccases as well as immobilized laccases onto inorganic, organic (natural or synthetic)and hybrid supports show excellent performance in the remediation of phenolic compounds from wastewater. In contrast to immobilized laccases, free laccases suffer from high prices, low operative stability, and inability to recoverand reuse in their native forms. Moreover, the possible mechanisms associated with oxidation of phenolic compoundsby the laccase-catalyzed systems are assessed.
HOW TO SELL THE GREEN FUTURE: THE ROLE OF STORYTELLING IN MARKETING SUSTAINABLE PRODUCTS
Matthew Lunde,Amin Rostami,Marat Bakpayev 글로벌지식마케팅경영학회 2023 Global Marketing Conference Vol.2023 No.07
This abstract summarizes an early-stage research proposal examining the benefits of storytelling in marketing green brands. Many research studies have been published in the last decade observing the growth and popularity of sustainable products (e.g., Bhardwaj et al., 2020; de Souza Correa et al., 2022; Haider, Shannon, & Poschis, 2022; Lunde, 2018; Rajogopal, Mahajan, & Priya, 2021; Skackuskiene & Vilkaite-Vaitone, 2022; among many others). Only some of these products offered immediate economic benefits to consumers when introduced. Consumers were skeptical of the sustainability of the products (e.g., Matthes & Wonneberger, 2014), consumers felt the prices were higher than unsustainable products (e.g., Juan, Hsu, & Xie, 2017), and consumers felt that the company was greenwashing (e.g., Cho & Taylor, 2020). However, the story of these businesses imagining a green future was the main driving force in attracting and convincing consumers to switch regardless of the cost and risk involved in the decision (e.g., Moshood et al., 2022). Getting exposed to these exciting stories, consumers want to join and be part of them by purchasing green products. For example, when sustainable Toyota Prius and Tesla cars were first introduced, there were more economical and best-performing cars in the crowded US market (i.e., Toyota.com, 2023; Tesla.com, 2023). However, unlike conventional combustion engine cars, they had a story to tell. Then, and today, the companies sell the imaginary of a green and sustainable future for humankind. It is the same with the sustainable apparel brand, Patagonia, which has gained popularity throughout the years (Patagonia.com, 2023). Their products are expensive compared to their unsustainable competitors. However, consumers are willing to pay the price to be a part of the story that the brand narrates, promising a more sustainable future.

Background: Breast cancer (BC) is the leading cause of oncological death for women, in both developed and developing countries. In Iran, breast cancer ranks first among cancers diagnosed in women. The aim of this study was to present the burden of this cancer including incidence, mortality and years life lost (YLL) due to breast cancer in Iranian women. Materials and Methods: National incidence data from the Iranian annual National Cancer Registration reports from 2003 to 2009 and national death statistics reported by the Ministry of Health and Medical Education from 1995 to 2010, stratified by age group, were included in this analysis. Also calculated YLLs provided by the Institute for Health Metrics and Evaluation (IHME) for the years 1990, 1995, 2000, 2005 and 2010 were employed to express the years lost due to BC for Iranian women. Results: The general mortality rate of breast cancer increased during these years from 0.96 to 4.33 per 100,000 and incidence increased from 16.0 to 28.3 per 100,000 for the years under study. YLLs calculated by IHME showed both increasing and decreasing patterns, with a tendency for stabilization. Conclusions: The burden of breast cancer for Iranian women is still increasing. Thus, health education programs to inform women regarding the signs and risk factors, and national screening to facilitate early diagnosis are needed for the female community in Iran.

Gastric cancer (GC) is one of the most common malignancies in the world. It is the first cause of cancer deaths in both sexes In Iranian population. Circulating insulin-like growth factor-one (IGF-1) levels have been associated for gastric cancer. IGF-1 protein has central roles involved in the regulation of epithelial cell growth, proliferation, transformation, apoptosis and metastasis. Single nucleotide polymorphism in IGF-1 regulatory elements may lead to alter in IGF-1expression level and GC susceptibility. The aim of this study was to investigate the influence of IGF-1 gene polymorphism (rs5742612) on risk of GC and clinicopathological features for the first time in Iranian population. In total, 241 subjects including 100 patients with GC and 141 healthy controls were recruited in our study. Genotypes were analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay with DNA from peripheral blood. The polymorphism was statistically analyzed to investigate the relationship with the risk of GC and clinicopathological properties. Logistic regression analysis revealed that there was no significant association between rs5742612 and the risk of GC. In addition, no significant association between genotypes and clinicopathological features was observed (p value>0.05). The frequencies of the CC, CT, and TT genotypes were 97%, 3%, and 0%, respectively, among the cases, and 97.9%, 2.1%, and 0%, respectively, among the controls. CC genotype was more frequent in cases and controls. The frequencies of C and T alleles were 98.9% and 1.1% in controls and 98.5% and 1.5% in patient respectively. Our results provide the first evidence that this variant is rare in Iranian population and it may not be a powerful genetic predisposing biomarker for prediction GC clinicopathological features in an Iranian population.
