در این تحقیق امکان ایجاد لایه های سطحی نازک حاوی ترکیبات بین فلزی پایه کروم روی آلیاژ آلومینیم 6061 با استفاده از آلیاژسازی سطحی توسط لیزر مورد بررسی قرار گرفت. ابتدا پوشش کروم به همراه لایه های اولیه مس و نیکل در جمع به ضخامت 15 میکرومتر از طریق آبکاری الکتریکی روی زیرلایه آلومینیم 6061پیش نشست شد و سپس تحت عملیات آلیاژسازی سطحی توسط لیزر nd:yag پالسی با توان ها و سرعت های روبش مختلف قرار گرفت...
در این پژوهش اتصال آلیاژ آلومینیوم 1100 به آلیاژ منیزیم az31 با فرآیند اصطکاکی اغتشاشی مورد بررسی قرار گرفت. با توجه به نتایج، محدودهی سرعت چرخش 400 تا 800 دور در دقیقه و سرعت حرکت 15 تا 30 میلیمتر بر دقیقه، در حالتی که ابزار تنها در قسمت منیزیمی اتصال وارد میشود، به عنوان شرایط بهینهی اتصال جهت ایجاد جوش بدون عیب مشخص گردید. تشکیل ترکیبات بین فلزی در منطقهی جوش در نتایج آزمون پراش اشعهی ایکس ن...
86 http://e-aair.org Cow’s milk allergy (CMA) accounts for most diagnosed food allergies, mainly in the first year of life. CMA can cause severe anaphylaxis. CMA management is based on strict avoidance and the prescription of rescue medication. Cow’s milk (CM) contains more than 40 proteins, including casein (Bos d 8), -lactalbumin (Bos d 4), and -lactoglobulin (Bos d 5), identified as major mi...
BACKGROUND Although considerable efforts have been made to develop diagnostic tools for predicting the outcome of oral food challenges, tests for predicting the outgrowth of food allergies are lacking. OBJECTIVE The aim of this study was to assess the diagnostic value of the wheal size and skin index (SI) (the ratio of an allergen-induced wheal to a histamine-induced wheal diameter) of the sk...
BACKGROUND IgE-mediated cow's milk allergy (CMA) is one of the most common food allergies in infants. It is still controversial whether the early introduction of cow's milk formula (CMF) prevents the development of CMA. OBJECTIVE We aimed to evaluate the duration and frequency of CMF ingestion as compere with exclusive breast-fed for preventing CMA in high-risk infants. METHODS We enrolled ...
BACKGROUND Amino acid-based formulas (Aaf) are increasingly used in children with cow's milk allergy (CMA). To be labeled hypoallergenic these formulas must demonstrate in clinical studies that they don't provoke reactions in 90% of subjects with confirmed CMA with 95% confidence when given in prospective randomized, double-blind, placebo-controlled challenge (DBPCFC) trials. The majority of av...
BACKGROUND Developmental disorders (DD), including autism spectrum disorder (ASD) and intellectual disability (ID), are a common group of clinical manifestations caused by a variety of genetic abnormalities. Genetic testing, including chromosomal microarray (CMA), plays an important role in diagnosing these conditions, but CMA can be limited by incomplete coverage of genetic abnormalities and l...
Huntington Disease (HD) is caused by an abnormal expansion of polyQ tract in the protein named huntingtin (Htt). HD pathology is featured by accumulation and aggregation of mutant Htt in striatal and cortical neurons. Aberrant Htt degradation is implicated in HD pathogenesis. The aim of this study was to investigate the regulatory role of chaperone-mediated autophagy (CMA) components, heat shoc...
The multi-tier Covariance Matrix Adaptation Pareto Archived Evolution Strategy (m-CMA-PAES) is an evolutionary multi-objective optimisation (EMO) algorithm for real-valued optimisation problems. It combines a nonelitist adaptive grid based selection scheme with the efficient strategy parameter adaptation of the elitist CovarianceMatrix Adaptation Evolution Strategy (CMA-ES). In the original CMA...
Extensive research on antiviral small molecules starting in the early 1970s has led to the identification of 10-carboxymethyl-9-acridanone (CMA) as a potent type I interferon (IFN) inducer. Up to date, the mode of action of this antiviral molecule has remained elusive. Here we demonstrate that CMA mediates a cell-intrinsic type I IFN response, depending on the ER-resident protein STING. CMA dir...
