In this study, a periodic zigzag channel with rectangular cross-section has been used in order to obtain a high-efficiency system for cooling a polymer electrolyte fuel cell. An appropriate function of fuel cells and enhancement of their lifetime require uniform temperature conditions of around 80°C. On the other hand, due to volume and weight constraints, a low-density compact heat exchanger i...

Wound healing is a natural response to restore the injured tissue to normal. Wound healing is also complicated process involving different cellular, molecular and biochemical mechanisms and various types of cytokines and growth factors. Calcium channel blockers belong to cardiovascular medicine and administrated to treatment of hypertension, angina and cardiac arrhythmia because of vasodilatory...

In this channel,we study rate region of a Gaussian two-way diamond channel which operates in half-duplex mode. In this channel, two transceiver (TR) nodes exchange their messages with the help of two relay nodes. We consider a special case of the Gaussian two-way diamond channels which is called Compute-and-Forward Multiple Access Channel (CF-MAC). In the CF-MAC, the TR nodes transmit their mes...

Thirteen repetitions of a cross-channel transect in the Khuran Channel within the Strait of Hormuz allowed the description of the mean flow and semidiurnal tidal properties of a northsouth transect. Water velocity profiles were obtained with a 614.4 kHz TRDI Work Horse Broadband ADCP along this 3.3 km long transect on 10 October 2014, the third day of secondary spring tide. The M2, M4 and M6 fr...

The housing market plays a significant role in the economies of countries, and as an asset price channel, is considered as one of the main channels for monetary transmission mechanism. Considering the structure of the country's economy and the characteristics of housing as a capital commodity, the assessment of the impact of housing investment on inflation is important. This research evaluates ...

El-Ajouz, S, Allsopp, RC & Evans, RJ. Cysteine scanning mutagenesis of the region Glu52 to Gly96 of the human P2X1 receptor refines a model of the ATP binding site and identifies residues that contribute to channel gating. Poster presentation at the Purines 2010 conference, Tarragona, Spain and at the UK Purine Club 2010 conference, Nottingham. El-Ajouz, S, Allsopp, RC & Evans, RJ. Molecular ba...

a. Gingival enlargement Gingival enlargement secondary to drug therapy is the most commonly reported oral manifestation of renal disease. It can be induced by cyclosporine and/or calcium channel blockers (Somacarrera et al., 1994; Kennedy and Linden 2000). b. Oral hygiene and periodontal disease The oral hygiene of individuals receiving hemodialysis can be poor. Deposits of calculus may be incr...

BACKGROUND HERG1 potassium channel plays a critical role in the cell proliferation. METHODS HERG1 protein expression was analyzed by immunohistochemistry (IHC) in 62 patients with oral leukoplakias and 100 patients with oral squamous cell carcinomas (OSCC). HERG1 mRNA levels were assessed by real-time reverse transcriptase-polymerase chain reaction (RT-PCR) in 22 patients with primary head an...

To channel students' interest in global oral health and prepare them to respond adequately to the health effects of globalization as future practitioners, new courses in dental curricula may be needed. This article documents the results of Harvard School of Dental Medicine (HSDM)'s new course, Global Oral Health: Interdisciplinary Approaches. To the authors' knowledge, this is the first course ...
