In this article, we investigate sufficient conditions for existence of maximal and minimal solutions to a coupled system of highly nonlinear differential equations of fractional order with mixed type boundary conditions. To achieve this goal, we apply monotone iterative technique together with the method of upper and lower solutions. Also an error estimation is given to check the accuracy of th...

ur names are very much part of what defines us as a person. The given name identifies us as individuals within the group in which we live and function. Normally, we are the only person identified by that particular name within the group. Most of us have given names that our parents liked for some reason or other, selected in a rather accidental fashion. Our surname is, of course, anything but a...

introduction: different vasoactive factors can modulate cardiovascular adaptation to hemorrhagic shock including nitric oxide (no). in this study we investigated the effect of  the no synthase inhibitor for treatment of  decompensated hemorrhagic shock in normotensive and hypertensive rats. methods: twenty‑four male wistar rats were divided into two groups: the normotensive and hypertensive gro...

Described is the classification of the main types of solutions, which make the “Solution” Line in the process of problem solving within the framework of the OTSM-TRIZ (1, 2, 3, 4) approach. The Mile Stones system was developed for educational proposes, but it is also helpful for avoiding some misunderstanding between members of a problem-solving team as well as between an OTSMTRIZ coach and his...

Objective(s): This study was performed to investigate the effects of mucosal acidification on mRNA expression and protein synthesis of cystathionine gamma lyase (CSE), cystathionine beta synthase (CBS), and mucosal release of H2S in gastric mucosa in rats. Materials and Methods:Thirty-two rats were randomly assigned into 4 groups (8 in each), including: the control group, HCl (10 mM) treated g...

In 1935, Shay and Gershon-Cohen showed that luminal perfusion of the duodenum of human subjects with sodium bicarbonate solution produced a rapid emptying of a barium sulphate meal from the stomach. More recently it was shown by Brown et al. (1966) that, in the dog, the instillation of alkaline solutions into the duodenum also increased motor activity in denervated, transplanted gastric pouches...
