1. 1. Remediation of per- and polyfluoroalkyl substances (PFAS) in contaminated water by sorption to pine- and spruce bark

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Rebecka Ayranci Dahlberg; [2023]
   Keywords : Per- and polyfluoroalkyl substances; sorption; pine bark; spruce bark; ultra-short-chain PFAS; short-and long-chain PFAS; elemental analysis; field-test;

   Abstract : PFAS are anthropogenic substances used in many different industrial operations and products because of their unique properties. Due to their negative impact on human health and environmental bioaccumulative characteristics different authorities have addressed the issue. In Sweden the limit is4 ng/L for four different PFAS in drinking water. READ MORE

3. 2. The initial steps in the pursuit to diagnose trimethylaminuria with liquid chromatography-tandem mass spectrometry and UniSpray ionization at CMMS

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Cristian Fransson; [2022]
   Keywords : ;

   Abstract : Trimethylaminuria is an autosomal recessive disorder characterized by a decreased oxidation capacity of trimethylamine to trimethylamine-N-oxide in the liver. The condition is diagnosed by estimating concentrations of trimethylamine and trimethylamine-N-oxide in human urine and then evaluating their respective creatinine ratios and the oxidation efficiency percentage.

4. 3. Method development and screening of extractable organofluorine (EOF) and targeted PFAS analysis in food packaging materials

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Nora Larsson; [2022]
   Keywords : Per- and polyfluoroalkyl substances PFAS ; Food packaging materials; Extractable organofluorine; Method development; Combustion ion chromatography; Targeted analysis;

   Abstract : Per- and polyfluoroalkyl substances (PFAS) have been manufactured and used in differentapplications for several decades, including food packaging materials. During the last 20 yearsthese compounds have been acknowledged as hazardous for humans and the environment, anddifferent regulations on PFAS have been established on both national and international levels.

5. 4. Classification of sequence tags from tandem mass spectrometry spectra using machine learning models

   University essay from Lunds universitet/Examensarbeten i bioinformatik

   Author : Júlia Ortís Sunyer; [2022]
   Keywords : Biology and Life Sciences;

   Abstract : Motivation: Proteomics is the large-scale study of all the proteins found in a cell, tissue or organism. In the last few years, and thanks to the development of mass spectrometry and bioinformatics, proteomics has led the research in several fields, ranging from medicine to agriculture. READ MORE

6. 5. Predicting Acute Kidney Injury In Sepsis Patients: A Machine Learning Approach

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Patrik Laurell; Dwight Lidman; [2022]
   Keywords : machine learning; sepsis; Technology and Engineering;

   Abstract : Sepsis-induced Acute Kidney Injury (AKI) is a common cause of death for sepsis patients, yet it is poorly understood by the medical community. Using Tandem Mass Spectrometry (MS/MS), the blood plasma of 135 sepsis patients has been analyzed to measure protein levels. READ MORE
