The SOS response in Escherichia coli is induced after DNA-damaging treatments including ultraviolet light. Regulation of the SOS response is accomplished through specific interaction of the two SOS regulator proteins, LexA and RecA. In ultraviolet light-treated cells, nucleotide excision repair is the major system that removes the induced lesions from the DNA. Here, induction of the SOS respons...

Atrial myxomas are uncommon in the pediatric population but are very important due to pursuant atrioventricular valve obstruction and systemic embolic events. Concerning multiple symptoms ranging from congestive heart failure to neurological deficits, the diagnosis of this disease is complicated. This paper reports a case of left atrium myxoma in a child treated with a surgical excision o...

The previously described mutator system of Caenorhabditis elegans var. Bergerac has as one of its targets unc-22, a previously uncloned gene on chromosome IV important in assembly and function of the body wall musculature. By assuming that the mutator activity involved transposition of the repetitive element Tc1 into the unc-22 gene we have succeeded both in cloning the unc-22 gene and in demon...

Abstract Background Benign breast tumors although classified as benign lesions but excising them remain a troublesome problem. Surgical excision for frightens most of female population suffering from such problem, which created an urgency to search safe and effective alternative. My aim was assess the efficacy vacuum-assisted biopsy (VAB) system removal in terms complete rate incidence complica...

PURPOSE The need for surgical excision in patients with ultrasound-guided core needle biopsy (CNB)-diagnosed atypical ductal hyperplasia (ADH) remains an issue of debate. The present study sought to validate a scoring system (the U score, for underestimation) that we have previously developed for predicting malignancy in CNB-diagnosed ADH. METHODS The study prospectively enrolled 85 female pa...

OBJECTIVE To describe the management of bilateral oral ranulas with the use of the da Vinci Si Surgical System and discuss advantages and disadvantages over traditional transoral resection. STUDY DESIGN Case Report and Review of Literature. RESULTS A 47 year old woman presented to our service with an obvious right floor of mouth swelling. Clinical evaluation and computerized tomography scan...

Brunnoma, is a benign tumor of duodenal wall. Usually present with anaemia. Endoscopy stomach and duodenum gives the diagnosis. Pedunculated lesion best managed by endoscopic snare cautery excision. Lesion close to pylorus makes endoscopy difficult. Hence mini-laparotomy, trans-gastric three port endo-luminal harmonic excision was done safely. Keyword: brunnoma, anaemia, endoluminal surgery
