Faster bowel recovery with superior haemorrhoidal artery preservation in patients undergoing sigmoidectomy for diverticular disease: A retrospective cohort study from the diverticular disease registry trial [PDF]

Journal of Minimal Access Surgery
Introduction: The pathogenesis of diverticular disease varies significantly and so does its clinical presentation. The procedure for left-sided diverticular disease is standardised, but there is still no consensus on the level of arterial ligation.

Evaluating the efficacy of eggshell-derived hydroxyapatite (EHA) and synthetic hydroxyapatite (SHA) in bone regeneration of maxillofacial defects-a randomized double-blind pilot comparative clinical-radiological study [PDF]

Journal of Oral Biology and Craniofacial Research
Background: Defects of the maxillofacial skeleton lead to functional, aesthetic, social, and behavioral problems, that make the person isolate from the mainstream of society. So, bone regeneration is needed for the overall health. Since long time various

Multi-mode operator for SHA-2 hash functions [PDF]

Journal of Systems Architecture, 2007
We propose an improved implementation of the SHA-2 hash family, with minimal operator latency and reduced hardware requirements. We also propose a high frequency version at the cost of only two cycles of latency per message. Finally we present a multi-mode architecture able to perform either a SHA-384 or SHA-512 hash or to behave as two independent SHA-
