This paper contributes to the solution of the energy crisis by investigating the stability of alcohols as e-fuels. The focus is on the investigation of the aging mechanism of the linear alcohols 1-hexanol and 1-octanol compared to the iso-alcohol 2-hexanol. It is analysed in detail how the time-dependent aging varies depending on the chain length and the position of the hydroxy-group, both in the liquid and in the gas phase. It is shown that a variety of aging products such as aldehydes, acids, short-chain alcohols and esters are formed during the aging of the n-alcohols by oxidation, decarboxylation, oxidative C-C bond cleavage and esterification. In contrast, the decomposition of the iso-alcohol is significantly lower. The results show that the total acid number is significantly higher for aged n-alcohols than for the aged iso-alcohos, while the kinematic viscosity decreases for all alcohols during aging. Carbon mass balancing shows that after accelerated aging for 120 hours, around 80% of the iso-alcohol is still present, compared to only around 57-63% for the n-alcohols. In addition, significantly fewer acids are formed with the iso-alcohol. In this study, iso-alcohols have a higher stability against thermo-oxidative aging compared to n-alcohols, showing their potential as e-fuels. Furthermore, the chain length of the alcohols has also an influence on aging, as more different aging products can be formed with increasing chain length.\r\n\r\nThis paper contributes to the solution of the energy crisis by investigating the stability of alcohols as e-fuels.

Extracellular and cytosolic PPi concentrations were measured by enzyme-linked bioluminescence assay. ALP and ENPP1 activity was determined spectrophotometrically. We further established a human cell culture model suitable for investigating PXE and related disorders without addition of artificial calcification triggers.\r\nResults\r\nIndependently of the experimental conditions, PXE fibroblasts revealed a higher degree of matrix calcification. We observed that matrix calcification was associated with altered gene expression of PPi metabolizing enzymes in PXE fibroblasts. In this context, PXE fibroblasts exhibited significantly higher expression of ALP and OPN and reduced mRNA expression and activity of ENPP1. Here, for the first time cytosolic and extracellular PPi levels were shown to be strongly reduced in PXE fibroblasts. We further showed that PPi concentration in bovine and human sera additives had a strong impact on matrix calcification. In a last experimental line, we demonstrated that addition of PPi analogs reduced matrix calcification of PXE fibroblasts most likely by reducing ALP and OPN mRNA expression, restoring ENPP1 activity and subsequently elevating PPi concentrations.\r\nConclusion\r\nThe results of our study along with recent findings point to the essential role of PPi as the central regulatory metabolites preventing matrix calcification in PXE. But what remains to be determined is the underlying molecular mechanism leading to depletion of PPi in PXE. We further suggest that supplementation of PPi analogs might counteract pathological calcification in PXE and related disorders.","lang":"eng"}],"keyword":["Pseudoxanthoma elasticum","Calcification","Pyrophosphate","Bisphosphonate","ABCC6","Tissue nonspecific alkaline phosphate","Ectonucleotide pyrophosphatase 1"]},{"_id":"12985","publication":"Clinical Biochemistry","title":"Variants in genes encoding pyrophosphate metabolizing enzymes are associated with Pseudoxanthoma elasticum","volume":47,"publication_status":"published","date_created":"2025-06-17T06:53:30Z","language":[{"iso":"eng"}],"citation":{"havard":"M.

Because of the great clinical variability between PXE patients the involvement of modifier genes was recently suggested. Therefore, we investigated the association of single nucleotide variants (SNVs) in selected candidate genes known to regulate cellular pyrophosphate metabolism.\r\nDesign and methods\r\nWe used RLFP analyses to evaluate the distribution of SNVs in alkaline phosphatase (ALP), ectonucleotide pyrophosphatase 1 (ENPP1) and ankylosis (ANKH) in DNA samples from 190 German PXE patients and 190 age- and sex-matched healthy controls. Statistical analyses were performed using Fisher exact test and Bonferroni correction.\r\nResults\r\nThe screening revealed three different SNVs in three genes, which were associated with PXE. The SNV c.1190-65C > A (rs1780329, minor allele frequency (MAF) patients: 0.17; controls: 0.11; P = 0.04) in the ALP gene was significantly more frequent in PXE patients. Furthermore, PXE was highly associated with ANKH p.A98A genotype TT (P = 0.0012), although the MAF was not different between patients and controls. After correction for multiple testing according to the Bonferroni method, one SNV in the ENPP1 gene (c.313 + 9G > T, rs7773477) remained significantly associated with PXE with significantly higher MAF values in the patient cohort (MAF: 0.04 vs. 0.00; P = 0.0024) and a high association with PXE susceptibility (OR 27.96).\r\nConclusion\r\nPolymorphisms in ALP, ENPP1 and ANKH are important genetic risk factors contributing to PXE.","lang":"eng"}],"keyword":["Pseudoxanthoma elasticum","Calcification","Tissue nonspecific alkaline phosphatase","Ectonucleotide pyrophosphatase 1","Ankylosis"],"status":"public","department":[{"_id":"DEP4010"}],"user_id":"83781","year":"2014","doi":"10.1016/j.clinbiochem.2014.07.003","date_updated":"2025-06-17T13:48:52Z","issue":"15","publisher":"Elsevier","type":"scientific_journal_article"}]
