The MWCNTs-COOH Paste Electrode (MCPE) was successfully used to study the electrochemical behavior of temozolomide in 0.2 M H2SO4 solution, phosphate buffer solution (0.1M PBS, pH 7.4) and 0.1M NaOH solution by Cyclic Voltammetry (CV) technique. The results exhibit that MCPE can remarkably enhance sensing and electrocatalytic activity towards the oxidation and reductio...

Strength reduction in structures like an aircraft could be resulted as cyclic loads over a period of time and is an important factor for structural life prediction. Service loads are emphasized at the regions of stress concentration, mostly at the connection of components. The initial flaw prompting the service life was expected by using the Equivalent Initial Flaw Size (EIFS) which has been re...

The novel corona virus disease (COVID-19) has caused a great pandemic since the end of 2019. A variety symptoms been identified for this disease. In case series we report 5 patients in different age groups who presented with cyclic vomiting as late complication COVID-19. All have gone through complete diagnostic process syndrome (CVS) including endoscopy. However, they all showed normal finding...

Two molecular species of repressible extracellular phosphodiesterases showing cyclic 2',3'- and cyclic 3',5'-nucleotide phosphodiesterase activities were detected in mycelial culture media of wild-type Neurospora crassa and purified. The two molecular species were found to be monomeric and polymeric forms of an enzyme constituted of identical subunits having molecular weights of 50,000. This en...

Periodic activities of Dictyostelium discoideum cells involve two types of oscillations, spike-shaped and sinusoidal. Spike-shaped oscillations are accompanied by the periodic synthesis and release of cyclic AMP, and cyclic AMP-activated cyclic AMP synthesis is believed to control these oscillations. Experiments described here call into question the importance of cyclic AMP in spike-shaped osci...
