objective(s): coronary artery disease (cad) is the leading cause of death in both male and female worldwide. the main cause of cad is the atherosclerosis of coronary arteries, which is, mostly caused by genetic alteration. 50% of such cases occur in mitotic cells where single-strand breaks occur spontaneously or due to ionizing radiation. x-ray repair cross-complementing protein 1 (xrcc1) as a ...

among the lesions induced by chemotherapeutic drugs, dna double-strand breaks (dsb) are considered the most serious ones that can result in cell death, if it is not properly repaired. homologous recombination (hr) pathway is the main system for dsb repair and xrcc3 has a key role in this pathway. protein activity can be affected by the xrcc3 polymorphism. thus, in this study, the association be...

Following low levels of UV exposure, Escherichia coli cells deficient in nucleotide excision repair (uvrA6 mutants) recover and synthesize DNA at near wild type levels, an observation that formed the basis of the post-replication recombination repair model. In this study, we characterized the DNA synthesis that occurs following UV-irradiation in the absence of nucleotide excision repair and sho...

This paper proposes a maintenance platform for business vehicles which detects failure sign using IoT data on the move, orders to create repair parts by 3D printers and to deliver them to the destination. Recently, IoT and 3D printer technologies have been progressed and application cases to manufacturing and maintenance have been increased. Especially in air flight industry, various sensing da...

BACKGROUND Enhancement of bond strength between new and old composite usually requires increased surface roughness of old composite to promote mechanical interlocking and subsequent coating with bonding agents to improve surface wetting and chemical bonding. So this study was carried out to evaluate and compare the effects of different surface treatments and repair materials on the shear bond s...

Field services are a particular type of after-sales service performed at the customer’s location where technicians repair malfunctioning machines. The inventory decisions about which spare part types to take to the repair site and in what quantities is called the repair kit problem. This problem is characterized by an order-based performance measure since a customer is only satisfied when all r...

BACKGROUND Traditional biomechanical evaluations of rotator cuff repair techniques employ cyclic loading of the supraspinatus tendon in an isolated medial direction. PURPOSE This study was conducted to evaluate 2 different rotator cuff repair techniques that are currently the subject of debate with cyclic loading and with internal and external humeral rotation to better simulate postoperative...

The very rapid development of the manufacturing industry requires companies to be able increase their productivity. Based on analysis production machine, it is calculated that Overall Equipment Effectiveness value only 81%, this figure still lower than world class standard. What Affects Low OEE Value Is Performance and Machine Setup Downtime. This Repair Done Using Implementation Design Single ...
