  2. 1. Lignin Conversion to Value-Added Small-Molecule Chemicals : Towards Integrated Forest Biorefineries

    Author : Omar Y. Abdelaziz; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aromatic monomers; biorefinery; catalysis; kraft lignin; lignin depolymerization; lignin valorization; microbial conversion; renewable chemicals; techno-economic analysis;

    Abstract : Lignin is the most abundant aromatic biopolymer on Earth and has significant potential as a feedstock for industrial use. Due to its intrinsic heterogeneity and recalcitrance, lignin has been regarded as a low-value side-product in the pulp and paper industry and in second-generation biorefineries. READ MORE

  4. 2. Hip fracture : risk factors and mortality

    Author : Bahman Y Farahmand; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Epidemiology; case-control study; hip fracture; body size; physical activity; socioeconomic status; marital status; smoking; alcohol; survival;

    Abstract : The objective of this thesis was to identify factors related to risk of hip fracture and mortality after the hip fracture. We used data from a large population-based case-control study in postmenopausal women aged 50-81 years during 1993-1995 who resided in six counties in Sweden. READ MORE

  5. 3. Role of lipoprotein structure and dynamics in disease development : from atherosclerosis to Covid-19

    Author : Yubexi Y. Correa M.; Marité Cárdenas; Valeria Rondelli; Malmö universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Health and society; Hälsa och samhälle;

    Abstract : Lipoproteins play a crucial role in lipid metabolism, serving as carriers for lipids such as cholesterol and triglycerides in the bloodstream. Atherosclerosis is a complex cardiovascular disease characterized by the accumulation of cholesterol-rich plaques in arterial walls, leading to narrowed and hardened arteries. READ MORE

  6. 4. Exploring novel roles of metabolic enzymes MTHFD2 and PFKFB3 in cancer genome stability and their potential as anticancer therapeutic targets

    Author : Nadilly Y Bonagas Villarreal; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Altered tumor metabolism has been described as early as the 1920s, but it was only in recent decades that proteomic and metabolomic studies revealed that the ways in which tumors rewire their nutrient and energy pathways are more diverse and have more implications for treatment outcome than previously thought. There is now a great interest in characterizing promising metabolic targets and identifying novel ways by which to exploit them for cancer treatment. READ MORE
