The outcome of endovascular treatment in acute superior mesenteric artery (SMA) thromboembolic occlusion is variable at best. We describe three patients who underwent urgent endovascular manual aspiration thrombectomy of the SMA, illustrating the good, the bad, and the ugly. The good: a 63-year-old male patient was admitted to our hospital for acute abdominal pain. Contrast-enhanced multidetect...
In this work, we aim to evaluate different Distributed Lock Management service designs with Remote Direct Memory Access (RDMA). In specific, we implement and evaluate the centralized and the RDMAenabled lock manager designs for fast network settings. Experimental results confirms a couple of hypotheses. First, in the traditional centralized lock manager design, CPU is the bottleneck and bypassi...
Data race conditions in multi-tasking software applications are prevented by serializing access to shared memory resources, ensuring data consistency and deterministic behavior. Traditionally tasks acquire and release locks to synchronize operations on shared memory. Unfortunately, lock management can add significant processing overhead especially for multicore deployments where tasks on differ...
Standard-dose heparin protocol (SDP) is the standard anticoagulant of unfractionated (UFH) for maintenance hemodialysis. To alleviate side effect heparin, low-dose (LDP) has been proposed, however, studies were scarce and inconclusive.
materials and methods in a double blind randomized trial study, 100 patients undergoing elective cardiac surgery were randomized to using heparinized (n = 50) or non-heparinized (normal) saline flush (n = 50) to maintain patency of arterial catheter after operation. indwelling arterial catheters were checked daily for acceptable arterial waveform for three days as primary outcome measures. resu...
heparin was isolated from whole clam tissue marcia opima . purification of multimilligram quantities of heparin from this tissue sample permitted a thorough examination of its anticoagulant activity characterization, which was partially purified by fractionation by anion exchange chromatography using deae cellulose column. the isolated crude and partially purified fractionated sample showed met...
We consider non-blocking synchronization for dynamic embedded real-time systems such as those that are subject to resource overloads and arbitrary activity arrivals. The multi-writer/multi-reader problem inherently occurs in such systems, when their activities must concurrently and mutually exclusive share data objects. We consider lock-free synchronization for this problem under the unimodal a...
Lock-free programming is a well-known technique for multithreaded programming. Lock-free programming is a way to share changing data among several threads without paying the cost of acquiring and releasing locks. On practice, parallel programming models must include scalable concurrent algorithms and patterns. Lock-free programming patterns play an important role in scalability. This paper is d...
