Introduction: To protect genomes of all organisms from internal and external damages and maintain the genome integrity and the continuity of life, repair system has been developed in all living cells. Defects in repair system are responsible for various kinds of disease including cancers and neurodegenerative diseases such as Multiple sclerosis (MS). The relationship between various compone...

background: congenital diaphragmatic hernia (cdh) occurs due to a failure in closing pleuroperitoneal membrane thus resulting in an incomplete diaphragm formation1, which allows passage of the abdominal viscera into the thorax.1,3 until 1995, the standard method for treatment of cdh was performed by open surgery through the abdomen or thoracic cavity. minimally invasive approach via thoracoscop...

Damage recognition is a key initial step in DNA repair. A recent study puts to rest the debate of whether XPD helicase 'verifies' the appropriateness of the DNA damage to be mended by the nucleotide excision repair machinery.

in this paper a new problem of three stage disassembly-assembly scheduling is introduced and reviewed. this problem, which was arisen from the aviation industry characteristics, is a generalization of the two stage assembly scheduling problem. products (helicopters) in the aviation industry return to assembler for annual overhaul repair services. in the first stage helicopters are disassembled ...

Background Ascending testis (AT) is one of the rare but serious complication that may occurs following inguinal hernia/hydrocele repair. We aimed to review our more than 7 years’ experience and discuss the possible mechanism through which the AT possibly occurs following inguinal hernia/hydrocele repair. Materials and Methods A retrospective analysis of 7,212 boys who had undergone inguinal her...

For many English as a Foreign Language (EFL) teachers working contingently with language learners’ problematic learner contributions in classroom interaction still remains a challenge. Drawing on conversation analysis methodology and using sociocultural and situated learning theories, this longitudinal case study traces the progressional changes in one Iranian English language teacher’s repairi...

Generally, the failure rate and the repair time of system components are constant parameters in reliability assessment of electric distribution systems. A failure of component is resulted from failing in the operation or overloading. In addition, there exist cases where, the repair times of components are small and tolerable from customer point of view. Thus, tolerable repair times may be overl...

this study compared the push-out bond strength of endosequence root repair material (errm) and bioaggregate (ba), new bioceramic materials, to that of mineral trioxide aggregate (mta) after incubation in phosphate-buffered saline (pbs), a synthetic tissue fluid, for either 1 week or 2 months.one-hundred and twenty root sections were filled with proroot mta, ba, or errm. each tested material was...
