Zeiske, Wolfgang, Ilse Smets, Marcel Ameloot, Paul Steels, and Willy Van Driessche. Intracellular pH shifts in cultured kidney (A6) cells: effects on apical Na1 transport. Am. J. Physiol. 277 (Cell Physiol. 46): C469–C479, 1999.—We report, for the epithelial Na1 channel (ENaC) in A6 cells, the modulation by cell pH (pHc) of the transepithelial Na1 current (INa), the current through the individu...

The fornix and hippocampus are critical to recollection in the healthy human brain. Fornix degeneration is a feature of aging and Alzheimer's disease. In the presence of fornix damage in mild cognitive impairment (MCI), a recognized prodrome of Alzheimer's disease, recall shows greater dependence on other tracts, notably the parahippocampal cingulum (PHC). The current aims were to determine whe...

BACKGROUND The purpose of this study was to examine factors associated with the implementation of case management (CM) interventions in primary health care (PHC) and to develop strategies to enhance its adoption by PHC practices. METHODS This study was designed as a systematic mixed studies review (including quantitative and qualitative studies) with synthesis based on the diffusion of innova...

Demand for lightweight, highly reflective and mechanically compliant mirrors for optics experiments has seen a significant surge. In this aspect, photonic crystal (PhC) membranes are ideal alternatives to conventional mirrors, as they provide high reflectivity with only a single suspended layer of patterned dielectric material. However, due to limitations in nanofabrication, these devices are u...

We use single-agent and multi-agent Reinforcement Learning (RL) for learning dialogue policies in a resource allocation negotiation scenario. Two agents learn concurrently by interacting with each other without any need for simulated users (SUs) to train against or corpora to learn from. In particular, we compare the Qlearning, Policy Hill-Climbing (PHC) and Win or Learn Fast Policy Hill-Climbi...

OBJECTIVE To determine the primary health care (PHC) physicians' knowledge, attitudes, and practices on asthma care in the sectors of Abha and Khamis Mushayt, Aseer Region, Kingdom of Saudi Arabia. METHODS We conducted a cross-sectional study in Aseer region, Saudi Arabia during the period from June to July 2001. Sixty-one PHC physicians were selected randomly through 2-stage stratified sampl...

The parahippocampal cortex (PHC) has been implicated in both place/scene processing and episodic memory. We proposed that this region should instead be seen as intrinsically mediating contextual associations and not place/scene processing or episodic memory exclusively. Given that place/scene processing and episodic memory both rely on associations, this modified framework provides a platform f...

BACKGROUND Burns are known as one of the most common and destructive forms of injury with a vast spectrum of consequences. Despite the discovery of various antibacterial and antiseptic agents, burn wound healing still has remained a challenge to modern medicine. Plants, with a valuable traditional support, have been considered as potential agents for prevention and treatment of disorders in rec...

Choices about forms of health care, including primary health care (PHC), are fundamentally political decisions, reflecting global and national power structures and alliances, changing economic conditions, emerging new health problems and health care challenges, and the development of new health technologies. However, these choices also reflect, and are often expressed in terms of, a philosophy ...

BACKGROUND The demand for HIV care and treatment services is increasing rapidly and strategies to sustain long-term care should be employed. The decentralisation and integration of HIV care and treatment services into primary healthcare (PHC) is vitally important in order to ensure optimal access to life-saving antiretroviral therapy and ongoing chronic care. Conversely, the PHC system is fraug...
