UNLABELLED Caries is a global public health problem, whose control requires the introduction of low-cost treatments, such as strong prevention strategies, minimally invasive techniques and chemical prevention agents. Nature plays an important role as a source of new antibacterial substances that can be used in the prevention of caries, and Brazil is the richest country in terms of biodiversity....

BACKGROUND Depression is characterized by poor executive function, but - counterintuitively - in some studies, it has been associated with highly accurate performance on certain cognitively demanding tasks. The psychological mechanisms responsible for this paradoxical finding are unclear. To address this issue, we applied a drift diffusion model (DDM) to flanker task data from depressed and hea...

This paper presents the FPGA implementation of the prototype for the Data-Driven Chip-Multiprocessor (D2-CMP). In particular, we study the implementation of a Thread Synchronization Unit (TSU) on FPGA, a hardware unit that enables thread execution using dataflow-like scheduling policy on a chip multiprocessor. Threads are scheduled for execution based on data availability, i.e., a thread is sch...

ACUTE RENAL FAILURE IS A DEVASTATING clinical problem with limited preventive modalities. Acute renal failure frequently occurs after ischemic-reperfusion injury, toxic nephropathy, and sepsis (2, 5, 12, 13, 19). The onset of acute renal failure is frequently associated with many other life-threatening complications, including sepsis and multiorgan failure (2, 3, 7). Unfortunately, the high mor...

Single bus. Shared-memory systems based on a single bus have some tens of processors, each one with a local cache, and typically suffer from bus saturation. A cache-coherence protocol in each cache snoops the traffic on the common bus and prevents inconsistencies in cache contents.’ Computers manufactured by Sequent and Encore use this kind of architecture. Because it provides a uniform access ...

Distributed Data Mining is the process of extracting hidden knowledge from distributed data sources. A number of DDM architectures are proposed during the last few years. Recently, Optimized Incremental Knowledge Integration Distributed Data Mining model is proposed. It is a mobile-agent based model that overcomes the drawbacks of the traditional models. In this paper, the classification mining...

Although the exact mechanism of prostaglandin E2(PGE2)-mediated cytoprotection has not been elucidated, its ability to induce cytoprotection in cell culture suggests this action occurs at the cellular level. The present studies were conducted to determine whether PGE2 induces protection against 2,3,5-(trisglutathion- S-yl)-hydroquinone [2,3,5-(trisglutathion- S-yl)-HQ]-mediated cytotoxicity in ...
