Labor pain can cause stress which causes excessive release of hormones such as catecholamines and steroids. Pain in the active phase is physiological that occurs for a longer time, we need an effort to deal with first stage labor. If labor not overcome, it will problems are only painful mother labor, but also have potential threaten life fetus. One technique be done reduce intensity provide acu...

for the polynomial planar vector fields with a hyperbolic or nilpotent critical point at the origin, the monodromy problem has been solved, but for the strongly degenerate critical points this problem is still open. when the critical point is monodromic, the stability problem or the center- focus problem is an open problem too. in this paper we will consider the polynomial planar vector fields ...

Background Subsequent to coronary angiography, procedures performed prevent bleeding may cause pain in the patient. In this study, we aimed determine effect of acupressure on level and hemodynamic parameters patients undergoing angiography. Method prospective, a two-arm (1:1), randomized controlled trial was conducted, with 124 angiography included. The randomly assigned study group ( n = 62) r...
