به منظور جمع آوری و شناسایی کنه های بالاخانواده ی raphignathoidea باغات و مزارع شهرستان های ماکو و چایپاره، نمونه برداری هایی در فصل زراعی سال 1391 از خاک و اندام های هوایی صورت گرفت. در این مطالعه حدود 1200 اسلاید تهیه گردید که منجر به شناسایی 5 خانواده، 11 جنس و 31 گونه متعلق به بالا خانواده ی raphignathoidea گردید. از بین این تعداد 7 گونه برای فون دنیا و 8 گونه برای فون کنه های استان آذربایج...
Accumulating preclinical and clinical evidence data suggests that compounds that selectively activate neuronal nicotinic acetylcholine receptor (nAChR) subtypes may have therapeutic utility for the treatment of several neurological disorders. In the present study, the in vitro pharmacological properties of the novel cholinergic channel modulator ABT-089 [2-methyl-3-(2-(S)-pyrrolidinylmethoxy)py...
Because modulation of cortical cholinergic neurotransmission has been hypothesized to represent a necessary mechanism mediating the beneficial cognitive effects of nicotine and nicotinic acetylcholine receptor (nAChR) subtype-selective agonists, we used choline-sensitive microelectrodes for the real-time measurement of ACh release in vivo, to characterize cholinergic transients evoked by nicoti...
ABT-089 [2-methyl-3-(2-(S)-pyrrolidinylmethoxy)pyridine dihydrochloride], a novel ligand at neuronal nicotinic acetylcholine receptors with reduced adverse effects and improved oral bioavailability relative to (-)-nicotine, was tested in a variety of cognitive tests in rats and monkeys. Administered acutely, ABT-089 only marginally improved the spatial discrimination water maze performance of s...
Description: Fluoride dentifrices were first introduced in the 1950s. [1] The first fluoride dentifrice contained stannous fluoride and was first marketed in 1955. Since then many studies have investigated the level of dose and the form of fluoride that is optimum in dentifrice formulations. Higher caries reduction was reported in the 70s in clinical trials that investigated the potency of usin...
Dialysis is one of the effective methods which has been used since 1955 for the treatment of patients suffering from renal failure( more often of its chronic type). The dialysis results in the elimination of waste materials like urea and creatinine from the body, on the other hand, it can affect the serum contamination of the dialysis fluid. Aluminium is one of trace elements which its serum le...

Although nicotine mediates its effects through several nicotinic acetylcholine receptor (nAChR) subtypes, it remains to be determined which nAChR subtypes directly mediate heightened anxiety during withdrawal. Relative success in abstinence has been found with the nAChR partial agonist varenicline (Chantix; Pfizer, Groton, CT); however, treatment with this drug fails to alleviate anxiety in ind...

all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
