This method is author’s innovative technique which follows number of applied surgical procedures on palate and uvula with only goal to advance functional results and avoid complications like velofaringeal insufficiency. Task of this method is to solve uvulopalato lateral obstruction and to expand oropharyngeal airway. It was introduced in the year 2000 by Dr. Vukoje. It requires strict indicati...

Environmental Health Perspectives • volume 120 | number 2 | February 2012 A 55 Food Additives (JECFA), which considered but did not include naphthalene among geno toxic and carcino genic PAHs evaluated (FAO/WHO 2006). Although well intentioned, the LOC values suggested by Rotkin-Ellman et al. (2012) do not appear to take into account the natural background occurrence of PAHs in foods in many ca...

Organophosphorus compounds (OPs) are potent inhibitors of acetylcholinesterase (AChE). Treatment for OP poisoning is by administration of atropine sulfate, an oxime, and diazepam. Oximes such as 2-PAM are used to reactivate OP-inhibited AChE so as to restore normal enzymatic function and serve as a true antidote. There are reports of non-enzymatic hydrolysis by oximes of acetylthiocholine in in...

An electrochemical sensor is introduced as a tool applicable for diagnosis of intoxication by cholinesterase inhibitors caused by the well-known nerve agent VX. The traditional Ellman method was chosen for comparison with the sensor's analytical parameters. Both methods are based on estimation of blood cholinesterase inhibition as a marker of intoxication. While Ellman´s method provided a limit...

The procedure of Dietz et al. (Clin. Chem. 19: 1309-1313, 1973) for plasma cholinesterase (EC 3.1.1.7) gives a background absorbance of 1.4 A when extended to erythrocyte cholinesterase (EC 3.1.1.8) measurement, because the peak absorbance of the reaction product, 5-thionitrobenzoate, coincides with the hemoglobin Soret band at 410 nm. Consequently, the precision of erythrocyte cholinesterase m...

factors such as oxidative stress and reduced acetylcholine level have been implicated in alzheimer’s disease (ad) pathology and recently there has been a trend towards natural product research to find potential sources of antioxidants and acetylcholinesterase inhibitors in the plants kingdom. centaurea is a genus with about 500 species world wild, many of them have shown to possess biologic act...

Novel acrylamide and methacryloyl carrying piperazine-dihydrofuran derivatives (3a-p) were designed obtained from radical cyclizations of unsaturated piperazine (1a-f) with 1,3-dicarbonyl compounds (2a-c) mediated by Mn(OAc)3. Obtained characterized spectroscopic methods. In vitro AChE inhibitory activites 3a-p evaluated against (Acetylcholinesterase) Ellman method test results showed that 3a, ...
