BACKGROUND Percutaneous, vacuum-assisted, large-gauge core needle biopsy (VACNB) provides an alternative to open surgical biopsy as an initial diagnostic tool for breast lesions, yet rates of underestimating malignant diagnoses remain sufficiently high to warrant surgical biopsy in some cases. The current study was performed to determine if the Breast Lesion Excision System (BLES) provides a fe...

The nucleotide excision repair pathway removes ultraviolet (UV) photoproducts from the human genome in the form of short oligonucleotides ∼ 30 nt in length. Because there are limitations to many of the currently available methods for investigating UV photoproduct repair in vivo, we developed a convenient non-radioisotopic method to directly detect DNA excision repair events in human cells. The ...

conclusions radio-guided localization of non-palpable breast lesions is an acceptable method because of technical facilitation, accurate localization and complete excision with limited complications. so it can be recommended as an alternative method for wire-guided localization. results pathologic results were benign in 90.5% and malignant in 9.5% of patients. post-operative margin of lesion wa...

BACKGROUND Conventional single-incision laparoscopic surgery has been successfully employed for treatment of ovarian endometriomas. However, this technique presents surgeons with formidable ergonomic challenges, that make its widespread adoption unlikely. Robotic assistance in single-incision laparoscopic surgery provides adequate instrument triangulation through a single fulcrum, while elimina...

The Mu transposons of the Robertsons's Mutator transposable element system in maize are unusual in many respects, when compared to the other known plant transposon systems. The excision of these elements occurs late in somatic tissues and very rarely in the germ line. Unlike the other plant transposons, there is no experimental evidence directly linking Mu element excision and integration. We h...

Background: There are different treatment options with variable results for the management of pyogenic granuloma (PG). The aim of this study was to evaluate and compare the cosmetic results and recurrence rate of classic surgical excision with a novel proposed method, curettage and punch excision of the vascular stalk (C&P;) ...

Objectives Our laboratory is developing a surgical robotic system to further improve dexterity and visualization that will allow for broader application of transnasal skull base surgery. To optimize this system, intraoperative force data are required. Using a modified curette, force data were recorded and analyzed during pituitary tumor excision. Design A neurosurgical curette was modified by t...
