Spatial organization of a chromosome in a nucleus is very important in biology but many aspects of it are still generally unresolved. We focused on tissue-specific features of chromosome architecture in closely related malaria mosquitoes, which have essential inter-specific differences in polytene chromosome attachments in nurse cells. We showed that the region responsible for X-chromosome atta...

PURPOSE We compared the effectiveness and complications associated with 2 common vasectomy occlusion techniques, namely clipping and excision of a small vas segment and thermal cautery with fascial interposition and an open testicular end. MATERIALS AND METHODS We retrospectively reviewed the computerized records of 3,761 men who underwent initial vasectomy at a single university hospital fam...

Modern production operating systems are large and complex systems developed over many years by large teams of programmers, containing many hundreds of thousands of lines of code. Consequently, it is extremely difficult to add significant new functionality to these systems [16, 1, 42]. In response to this problem, a number of recent research projects have addressed the issue of extensible operat...

BACKGROUND This study has been conducted with the aim of evaluating modified T-plate interpositional arthroplasty. METHODS A prospective comparative study in patients admitted with temporomandibular joint ankylosis. Ankylotic temporomandibular joint arthroplasty included condylectomy gap arthroplasty in 7, temporalis muscle flap interpositional arthroplasty in 8, and modified T-plate interpos...

Distributed computing continues to be an alphabet-soup of services and protocols for managing computation and storage. To live in this environment, applications require middleware that can transparently adapt standard interfaces to new distributed systems; such software is known as an interposition agent. In this paper, we present several lessons learned about interposition agents via a progres...
