Is phenytoin a safe agent for staple line recovery after gastric sleeve surgery in rats?
(Turkish Association of Trauma and Emergency Surgery, 2023)BACKGROUND: The most challenging and mortal complication of gastric sleeve surgery (SG) is staple line leakage. Although many agents have been used for increasing tissue healing on the stapler line, there is still no ... -

Synthesis, crystal structure, spectroscopic, luminescence studies and hirshfeld surface analysis of blue light emitting heterometallic MnIII-NiII complex
(Pleiades Publishing, 2023)The synthesis, crystal structure, spectroscopic, luminescence properties and Hirshfeld surface analysis of a new heterometallic complex, [Mn(L)(H2O)(CH3CH2OH)]2[Ni(CN)4], (H2L = N,N′-bis(3,5-di-t-butylsalicylidene)-1,2-p ... -
Real data-based optimal control strategies for assessing the impact of the Omicron variant on heart attacks
(Amer Inst Mathematical Sciences-AIMS, 2023)This paper presents an investigation into the relationship between heart attacks and the Omicron variant, employing a novel mathematical model. The model incorporates two adjustable control parameters to manage the number ... -
Thin film preparation of polyphenol oxidase enzyme (PPO) and investigation of its organic vapor interaction mechanism
(Institute of Physics, 2023)This study investigated spin coated thin films of polyphenol oxidase (PPO) enzyme as vapor sensor to detect chloroform, acetone, ethyl acetate, isopropyl alcohol and toluene. Thin film of enzyme was produced onto a ... -
On statistical submanifolds in manifolds of quasi-constant curvature
(DergiPark, 2023)We mention some properties of statistical submanifolds in statistical manifolds of quasi-constant curvature. We obtain Chen first inequality and a Chen inequality for the δ(2, 2)-invariant for these manifolds. -
Curvature invariants for anti-invariant riemannian submersions from cosymplectic space forms
(Springer Basel AG, 2023)We consider anti-invariant Riemannian submersions from cosypmlectic space forms. We also give examples such anti-invariant Riemannian submersions. We obtain curvature inequalities involving the Ricci curvature and the ... -
Effect of surface modification and sodium dodecyl sulfate (SDS) on thermal properties of PMMA/SWCNT nanocomposites

Interpolative contractions and discontinuity at fixed point
(Universidad Politecnica de Valencia, 2023)In this paper, we investigate new solutions to the Rhoades’ discontinuity problem on the existence of a self-mapping which has a fixed point but is not continuous at the fixed point on metric spaces. To do this, we use the ... -
On the solutions of some recent open problems in metric fixed point theory
