Background. The role of multivisceral resection, in the setting of locally advanced gastric cancer, is still debated. Previous studies have reported a higher risk for perioperative morbidity and mortality, with limited objective benefit in terms of survival. Patient. A male patient, 55 years old, was admitted to the clinic of surgery for surgical treatment of bleeding gastric ulceration. Preope...

Although plan space planners have been shown to be flexible and efficient in plan generation, they do suffer from the problem of " looping' that is they may spend an inordinate amount of time. doing locally seemingly useful but globally useless refinements In this paper I review the anatomy of looping and argue that looping is intimately tied to the production of non minimal solutions I then pr...

The incidence of birth injuries has decreased considerably because of the identification of risk factors at an earlier stage and taking the decision for caesarian section (LSCS) at proper time. Fractures, nerve palsies and central nervous system injuries comprise the majority of "birth injuries." In this study, we report a newborn that had a birth injury during LSCS. The baby sustained a penetr...

Chromosomes must be highly compacted and organized within cells, but how this is achieved in vivo remains poorly understood. We report the use of chromosome conformation capture coupled with deep sequencing (Hi-C) to map the structure of bacterial chromosomes. Analysis of Hi-C data and polymer modeling indicates that the Caulobacter crescentus chromosome consists of multiple, largely independen...

Telemetry networks often operate in challenged wireless environments, resulting in periods of disconnection. Our delay tolerant networking (DTN) gateway dynamically detects disruptions in connectivity and buffers telemetry data until connectivity is reestablished. When the connection is resumed, all buffered data is transmitted automatically in order to backfill any gaps in the telemetry stream...

Efforts to successfully restore life in cardiac arrest victims are formidably challenging. They require not only that cardiac activity be initially reestablished but that injury to vital organs be prevented or minimized. In this article, we discuss the effects that cardiac arrest and resuscitation have on the myocardium, describing first the functional myocardial abnormalities that occur during...

We present a method for the design of nonmasking fault-tolerant programs. In our method, a set of constraints is associated with each program. As long as faults do not occur, the constraints are continually satissed under the execution of program actions. Whenever some of the constraints are violated, due to certain faults, all constraints are eventually reestablished by subsequent execution of...

Borrelia burgdorferi, which causes Lyme disease in humans, has an unusual genome composed of a linear chromosome and up to 21 extrachromosomal elements. Experimental data suggest that two of these elements, linear plasmids lp25 and lp28-1, play essential roles for infectivity in mice. In this study, we prove the essential natures of these two plasmids by selectively displacing lp25 or lp28-1 in...

With the proliferation of mobile computing devices we witness an increasing demand for applications supporting collaboration for wireless mobile devices, where the possibility of temporary losing the connection is considerable. We present here a novel framework that allows users to work offline and then to merge the local data with the global application state when the connection is reestablish...

This study examined the influence of tibio-femoral conformity on anteroposterior (AP) knee stability during stair descent, particularly with a dished cruciate sacrificing (CS) design. A joint simulator simulated stair descent of cadaveric knees. Tibio-femoral displacement was measured. Knees were tested in intact, ACL-deficient, and TKA with cruciate-retaining (CR), CS and posterior-stabilizing...
