BACKGROUND The goal of this study was to identify the in vivo effects in patients with hyposalivation of a novel slowly dissolving adhering test disc upon on enamel remineralization, oral biofilm, salivary production, pH and buffering, gingival health, and on self-evaluation of oral well-being. METHODS Five subjects with xerostomia wore custom made retainers carrying 5 demineralized enamel ch...

Phenotypic variation results from the balance between sources of variation and counteracting regulatory mechanisms. Canalization and developmental stability are two such mechanisms, acting at two different levels of regulation. The issue of whether or not they act concurrently as a common developmental buffering capacity has been subject to debate. We used geometric morphometrics to quantify th...

We propose a systematic method to determine the lower bound for internal buffering of practical CIOQ switching systems. To this end we introduce a deterministic traffic scenario that stresses the global stability of finite output queues. We demonstrate its usefulness by dimensioning the buffer capacity of the CIOQ under such traffic patterns. Compliance with this property maximizes the performa...

An increased intestinal permeability is associated with several diseases. Previously, we have shown that dietary Ca decreases colonic permeability in rats. This might be explained by a calcium-phosphate-induced increase in luminal buffering capacity, which protects against an acidic pH due to microbial fermentation. Therefore, we investigated whether dietary phosphate is a co-player in the effe...

Astrocytic gap junctions have been suggested to contribute to spatial buffering of potassium in the brain. Direct evidence has been difficult to gather because of the lack of astrocyte-specific gap junction blockers. We obtained mice with coupling-deficient astrocytes by crossing conditional connexin43-deficient mice with connexin30(-/-) mice. Similar to wild-type astrocytes, genetically uncoup...

This paper elaborates on seamless handover support for wireless IP multicast networks with the use of a novel mobility management mechanism. The latter enables mobile nodes with active multicast sessions to execute seamless remote subscriptions while changing their network attachment point and is formulated by extending the unicast ‘‘Fast Handovers for Mobile IPv6’’ protocol (FMIPv6). The propo...

CONTEXT In the gastroesophageal reflux disease (GERD), a highly prevalent digestive disorder, gastric content may return to the esophagus and reach the mouth, thus leading to a small number of carious lesions and high incidence of dental erosion. Since saliva plays a major role in oral homeostasis, evaluating salivary parameters is necessary in attempting to explain such outcome. OBJECTIVES T...

In this paper, conventional main memory and disk storage layers are merged into a single memory layer using a combination of PRAM and NAND Flash memories, which is called as an integrated memory-disk (IM-D) non-volatile memory structure. The IM-D memory architecture consists of a dual buffering IM-D adapter, an array of SLC/MLC PRAM/Flash hybrid IM-D memory, and an associated memory management ...

Shallow coral reefs threatened by climate change must be spatio-temporally analyzed in terms of their protection of coastal human populations. This study combines Japanese spatio-temporal gradients of population/asset and coral buffering exposure to stress-inducing and stress-mitigating factors so that the socio-economic and ecological (SEE) resilience tied to coral reefscapes can be regionally...
