DEVELOPMENT AND VALIDATION OF NOMOGRAM TO PREOPERATIVELY PREDICT INTRAOPERATIVE CEREBROSPINAL FLUID LEAKAGE IN ENDOSCOPIC PITUITARY SURGERY: A RETROSPECTIVE COHORT STUDY

BackgroundPituitary adenomas (PAs) are the most common tumor of the sellar region.PA resection is the preferred treatment for patients with clear indications for surgery.Intraoperative cerebrospinal fluid (iCSF) leakage is a major complication of PA resection surgery.Risk factors for iCSF leakage have been studied previously, but a predictive nomog

The purpose: to conduct field studies to determine the vertical settlement in the body and assess the safety of the earthfill dam of the Lyangar reservoir.One of the ways to ensure the safe condition of earthfill dams during operation is to conduct field studies in the facility.One of the factors leading to the overflow Candle Holders over the stru

Shark jaws exhibit teeth that are arranged into distinct series and files and display great diversities in shapes and structures, which not only is related to their function (grasping, cutting, crushing) during feeding, but also bear a strong phylogenetic signal.So far, most research on the relationship between shark teeth and feeding ecology and s

Abstract The charcoal production when performed in woods with high moisture content negatively impacts the pyrolysis and causes an increase of greenhouse emissions.The aim of this study was to investigate the effects of moisture on the production and quality of charcoal for the pig iron industry.The slow pyrolysis of Eucalyptus Color Depositing Sha
