background a gunshot wound to the lower extremity with combined skeletal and vascular injuries can be difficult to manage. in clinical practice, it is not always possible to assemble a multispecialty team to work seamlessly to attain this goal, and the end result may be unnecessary prolonged ischemic time. a covered endovascular stent (evs) can be used initially to restore perfusion without nee...

introduction: the pericranial flaps' benefits have been described in many otolaryngologic, maxillofacial and plastic surgery literature. the benefits ar e due to the pericranial flaps unique characteristics including good flexibility and mobility, very rich blood supply from several arterial sources and access to sufficient bulk of the flap without any need for distant surgical sites. usin...

abstract: introduction & objective: postoperative pain management and narcotic usage after inguinal hernia repair is an important concern for anesthesiologists and surgeons. the purpose of this study was to find out whether the use of local anesthetic nerve block in ilioinguinal and iliohypogastric region by bupivacaine could reduce postoperative pain and hospital admission periods after inguin...

now-a-days truncus arteriosus has been known as “common arterial trunk” (cat) and is an uncommon congenital cardiac defect presenting in about 1-3% congenital heart disease. environmental and genetic factors effects on incidence of cat and other conotruncal anomalies. the majority patients with cat and 22q11 deletion have other anomalies such as hypoplasia or aplasia of the thymus or parath...

abstract   background: despite being the largest rotator cuff tendon of the shoulder, the function and clinical relevance of subscapularis pathology has been largely ignored in the literature. although many studies have focused on subscapularis tears recently, majority of them reported techniques for open repair. the advent of arthroscopy and arthroscopic repair techniques has opened new fronti...

The present investigation deals with a machine repair problem consisting of cold and warm standby machines. The machines are subject to breakdown and are repaired by the permanent repairman operating under N-policy. There is provision of one additional removable repairman who is called upon when the work load of failed machines crosses a certain threshold level and is removed as soon as the wor...

X-ray Repair Cross Complementing protein 1 (XRCC1) acts as a scaffolding protein in the converging base excision repair (BER) and single strand break repair (SSBR) pathways. XRCC1 also interacts with itself and rapidly accumulates at sites of DNA damage. XRCC1 can thus mediate the assembly of large multiprotein DNA repair complexes as well as facilitate the recruitment of DNA repair proteins to...

Cloning of the OGG1 gene from Saccharomyces cerevisiae has revealed that DNA glycosylases are not necessarily conserved throughout phylogeny, yet there is a DNA-repair protein superfamily with a wide substrate specificity found from bacteria to man.

In this investigation, the explicit expressions for reliability function and mean time to failure (MTTF) of a repairable system with provision of spares and removable multi-repair facility have been established. In removable repairmen strategy, the repairmen turn on when there are N or more than N failed units and turn-off when system is empty. The failure times of operating/spare units and rep...
