Extraction and quantitation of fentanyl in exhaled breath condensate using a magnetic dispersive solid phase based on graphene oxide and covalent organic framework composite and LC-MS/MS analysis.

Free fentanyl is responsible for its pharmacological effects, but its total concentration is typically determined for therapeutic drug monitoring purposes. Determination of fentanyl concentration can help reduce the prescribed doses, leading to fewer side effects and increased effectiveness. Therefore, predicting free drug concentration in pharmaceutical research is crucial.

The Effects of Adding Probiotic, Alone and in Combination With Zinc, to Routine Treatment on Recurrence of Hepatic Encephalopathy, Quality of Life, and Sleep Quality in Patients With Cirrhosis: An Open-Label Randomized Controlled Trial.

Overt hepatic encephalopathy (OHE) is a common complication of decompensated cirrhosis. This study aimed to assess the effects of probiotic, alone and in combination with zinc, on OHE recurrence, Model for End-stage Liver Disease (MELD) score, ammonia level, health-related quality of life (HRQoL), and sleep quality in patients with cirrhosis. We performed an open-label randomized controlled trial on patients with decompensated cirrhosis with a previous history of OHE.

Analysis of indoxyl sulfate in biological fluids with emphasis on sample preparation techniques: A comprehensive analytical review.

The uremic toxin indoxyl sulfate (IS) has been related to the development of various medical conditions notably chronic kidney disease (CKD). Hence, quantification of this biomarker in biological fluids may be a diagnostic tool to evaluate renal system functionality. Numerous analytical methods including liquid chromatography, gas chromatography, spectroscopy, and electrochemical techniques have since been used to analyze IS in different biological fluids.

Determination of indoxyl sulfate by spectrofluorimetric method in human plasma through extraction with deep eutectic solvent.

A rapid and efficient analytical method was established to quantify indoxyl sulfate (IS) in plasma through extraction technique with a deep eutectic solvent (DES) and spectrofluorimetric method. DES (choline chloride: urea) was mixed with plasma samples for the extraction of IS, followed by the addition of dipotassium hydrogen phosphate (KHPO) solution to form an aqueous two-phase system. The fluorescence intensity of IS which was first extracted to the DES-rich-phase and then back-extracted into the salt-rich-phase, was measured by spectrofluorimetric method.

The efficacy of topical formulation on hemorrhoid disease: A randomized, double-blind, placebo-controlled trial.

Background: The topical application of boron has been significantly associated with intensifying wound healing. Using 3% boric acid in deep wounds significantly contributes to wound healing and reduces the duration of hospitalization in the intensive care. The objective of this study was to assess the therapeutic impact of a topical gel containing on the management of wounds resulting from grade 1 to 3 hemorrhoids.
