BACKGROUND Alzheimer's disease (AD) is a common form of age-related dementia, characterized by deposition of amyloid Aβ plaques, neuroinflammation and neurodegeneration. N-methyl-D-aspartate receptors (NMDAR) are postsynaptic glutamate receptors that play a role in memory formation and are targets for memantadine, an anti-AD drug. Nitric oxide (NO)(More)
The world is extremely diverse and its diversity is obvious in the cultural differences and the large number of spoken languages being used all over the world. In this sense, we need to collect and organize a huge amount of knowledge obtained from multiple resources differing from one another in many aspects. A possible approach for doing that is to think(More)
The inhibitory glycine receptor, a ligand-gated ion channel that mediates fast synaptic inhibition in mammalian spinal cord and brainstem, is potently and selectively inhibited by the alkaloid strychnine. The anthelminthic and anticonvulsant ivermectin is a strychnine-independent agonist of spinal glycine receptors. Here we show that ivermectin is an(More)
Until the beginning of the 1980s, nitric oxide (NO) was just a toxic molecule of a lengthy list of environmental pollutants such as cigarette smoke and smog. In fact, NO had a very bad reputation of being destroyer of ozone, suspected carcinogen and precursor of acid rain. However, by the early 1990s it was well recognized by the medical research community.(More)
In this paper we propose a new form of Padé-II equation, namely, a combined Padé-II andmodified Padé-II equation.Themapping method is a promising method to solve nonlinear evaluation equations. Therefore, we apply it, to solve the combined PadéII and modified Padé-II equation. Exact travelling wave solutions are obtained and expressed in terms of hyperbolic(More)
The functional and cost advantages of Internet telephony are evident. By today's technical standards, however, Voice Over IP (VOIP) is still less secure than traditional telephony. At the same time, the hacker scene is constantly looking for new weak spots and developing ingenious methods of attack to gain access to confidential information and penetrate(More)

Some Telco customers have multiple "Subscriber-Identity-Modules" or SIM cards across competing mobile operators or within the same operator. Multi-SIM detection is beneficial to telecommunications operators in tuning campaigns, acquiring usage from competitors, and retaining customers. The goal was to develop and materialize the techniques required to build(More)
