Xerostomia is defined as a subjective sensation of having a dry mouth (Fox et al., 1987) and is reported by the patient (Guggenheimer & Moore, 2003; Moore et al., 2001). The subjective feeling of dry mouth (xerostomia) is one of the oral manifestations of diabetes (Sreebny et al., 2006; von Bültzingslöwen et al., 2007). Xerostomia results from a reduction in saliva secretion, although it may oc...
استفاده از لاستیکهای فرسوده به منظور تسلیح خاکهای سست در بستر راهها (bosscher et al., 1997; heimdahl and druscher,1999)، کنترل فرسایش در خاکها (poh and broms, 1995)، پایداری سازی شیبها (poh and broms, 1995; garga and o’shaughnessy, 2000a)،پشت ریز سازه های نگهبان به عنوان مصالح سبک وزن (bosscher et al., 1997; lee, et al., 1999; garga and o’shaughnessy, 2000b) ، به عنوان مصالح فیلتر در مراکز دفن ...
Visualizing molecular structures in the course of a reaction process is one of the major grand challenges in chemistry, biology and physics. In particular, most chemical and biologically relevant reactions occur in solution, and solution-phase reactions exhibit rich chemistry due to the solute-solvent interplay. Studying photo-induced reactions in the solution phase offers opportunities for und...
Reliable global estimates of forest biomass and its dynamics are critically important for understanding the global carbon cycle and its dynamics (e.g., Bellassen et al. 2011). Many studies have been published regarding the estimation of above-ground biomass using airborne or satellite analog lidar systems (e.g., Nelson et al. 1988; Naesset 2002; Drake et al. 2003; Popescu et al. 2003; Lim and T...
Monosodium L-glutamate (MSG) functions as a signal for dietary protein. In the tongue, glutamate binds presumably to taste cell chemoreceptors which, upon being activated, alter the firing rate of innervating sensory nerves. It has just recently been hypothesized that several G protein coupled receptors (GPCR) acted as umami receptors (Chaudhari et al., 2000; Li et al., 2002; Nelson et al., 200...
The pathogenesis of HIV/SIV encephalitis (HIVE/SIVE) remains incompletely understood, but is associated with alterations in the blood brain barrier. In animals infected with pathogenic strains of simian immunodeficiency virus (SIV), such as SIVmac239 and SIVmac251, the virus can be consistently found in the central nervous system (CNS) within 10 to 14 days of infection: at the time of peak vire...
استفاده پایدار و سالم از محیط زیست و منابع طبیعی و ملاحظات مرتبط با سلامت انسان از مهم ترین موضوعات مورد دغدغه بشر است(rosenberg et al; 1993). این ملاحظات به شدت با کشاورزی، اکولوژی و محیط زیست مرتبط می باشد. در این بین، زیست شناسی به خصوص زیست شناسی گیاهی مهم ترین نقش را ایفا می نماید، و با توجه به این که گیاهان تنها منبع تجدید شونده و هم چنین مواد و انرژی سازنده را تشکیل می دهند، بنابراین زیس...
In the early 1990s, Iijima (1991) discovered a onedimensional (1D) nanostructure, the carbon nanotube (CNT), which sparked an entirely new avenue within nanoscience and nanotechnology. Nanowires (NWs) (Cui and Lieber 2001), nanorods (Li and Alivisatos 2003), nanotubes (Wang and Li 2003), and nanobelts (Pan et al. 2001) of various materials have been successfully synthesized shortly afterwards. ...
Regarding our article on the association of androgen deprivation therapy (ADT) with increased Alzheimer’s disease risk, Bowen et al, Froehner and Wirth, Leow et al, and Brady et al highlight a number of significant considerations that will prove important in the design of future studies that investigate the association of ADT and Alzheimer’s disease. We agree with Bowen et al and Leow et al tha...
Studies of cortical network function on the basis of multiple single-neuron recordings have revealed neuronal interactions which depend on stimulus and behavioral context. These interactions exhibit dynamics on several different time scales, with time constants down to the millisecond range (Grün et al. 2002a,b, Gütig et al. 2002, 2003, Heck et al. 2002, Riehle et al. 1997, Vaadia et al. 1995)....
