The effect of isoflurane versus propofol-based total intravenous anesthesia on hemodynamic stability, intraoperative blood loss, surgical field quality, recovery characteristics, and complications in patients undergoing posterior lumbar fusion surgery: a randomized clinical trial.

Introduction: General anesthesia is commonly used for spinal surgeries, achieved through inhalational methods or total intravenous anesthesia (TIVA). This study compared propofol-based TIVA with isoflurane anesthesia in patients undergoing posterior lumbar fusion surgery. Primary outcomes - intraoperative blood loss, surgical field quality, and hemodynamic stability - were selected for their direct impact on patient safety and surgical outcomes.

Predictors of intention to sign an organ donor card among Iranian clinical nurses: an application of the expanded organ donation model.

Introduction: Nurses are the first line of healthcare professionals who provide ongoing care to donors and their families. The intention of nurses to sign the organ donor card and the factors affecting it are important in the field of organ donation. The aim of the present study was to predictors of intention to sign an organ donor card among clinical nurses based on the expanded organ donation model.

Application of unfolded principal component analysis-radial basis function neural network for determination of celecoxib in human serum by three-dimensional excitation-emission matrix fluorescence spectroscopy.

This study describes a simple and rapid approach of monitoring celecoxib (CLX). Unfolded principal component analysis-radial basis function neural network (UPCA-RBFNN) and excitation-emission spectra were combined to develop new model in the determination of CLX in human serum samples. Fluorescence landscapes with excitation wavelengths from 250 to 310nm and emission wavelengths in the range 280-450nm were obtained.
