Introduction. Building block chemicals, such as butanol, can be produced via fermentation and biobased feedstocks as a more sustainable alternative compared to the current petrochemical methods. However, the butanol fermentation is subjected to low product titres (<20 g/L) due to product inhibition of the bacteria [1]. To overcome this continuous fermentation can be applied, as it offers considera
Background: There are known associations between cardiovascular disease (CVD)-related plasma proteins and spirometry measures. Diffusing capacity for carbon monoxide (DLCO) measures gas exchange that can be impaired both by lung and heart diseases. We aimed to study the associations between DLCO and CVD-linked plasma proteins in a population-based cohort without airflow obstruction. Methods: 89 CV
This study reports the synthesis and characterization of heterogeneous acid catalysts derived from rice husk biochar, modified by sulfonation and Ce(NO3)3·6H2O (cerium (III) nitrate hexahydrate) impregnation, for fatty acid esterification using methyl acetate as a glycerol-free reaction route. The research aims to valorize agricultural residues as renewable and sustainable precursors for solid aci
Today, we live in an age that is continually witnessing tension, strife and terrorism as a direct product of unequal distribution of wealth and opportunities for a good life. In Uganda for over two and half decades, war, insurgency and deprivation have been the realities of the people living in Northern Uganda. This evidently has lead to an imbalance in the Ugandan society with the North standing

Analyses of intraspecific genetic structure can promote the conservation of genetic diversity of rare or declining plant species by enabling identification of proper management units. Here we investigate the genetic structure of the annual hemiparasitic herb Rhinanthus angustifolius to evaluate the genetic distinctness of two currently described subspecies and three habitat-related groups of popul
Aims. The glycosphingolipid beta-galactosylceramide-3-O-sulfate (sulfatide) is present in the secretory granules of the insulin producing beta-cells and may act as a molecular chaperone of insulin. The final step in sulfatide synthesis is performed by cerebroside sulfotransferase (CST) (EC 2.8.2.11). The aim of this study was to investigate whether two single nucleotide polymorphisms (SNP), rs2267
Neutrophilic granulocytes contain the 55 kDa bactericidal/permeability-increasing protein (BPI). BPI binds to lipopolysaccharides (LPS), and exerts bacteriostatic and bactericidal effects against a wide variety of Gram-negative bacterial species. We have investigated the subcellular location of BPI in immature and mature neutrophils using cryotechnique for immunoelectron microscopy. BPI was found
Inflammation and ischemia have a synergistic damaging effect in the immature brain. The role of tumor necrosis factor (TNF) receptors 1 and 2 in lipopolysaccharide (LPS)-induced sensitization and tolerance to oxygen-glucose deprivation (OGD) was evaluated in neonatal murine hippocampal organotypic slices. Hippocampal slices from balb/c, C57BL/6 TNFR1(-/-), TNFR2(-/-), and wild-type (WT) mice obtai
Bacteria can cause life-threatening infections, such as pneumonia, meningitis, or sepsis. Antibiotic therapy is a mainstay of treatment, although antimicrobial resistance has drastically increased over the years. Unfortunately, safe and effective vaccines against most pathogens have not yet been approved, and thus developing alternative treatments is important. We analyzed the efficiency of factor
Looking at two historical romances by women writers, Kathleen Graves’ Exile: A Tale of Old Tasmania (1945) and Isabel Dick’s Wild Orchard (1946), this article seeks to examine narratives of an early nineteenth-century Van Diemen’s Land that are apparently at odds with the 1940s Tasmania it was to become. Drawing on Giorgio Agamben’s “state of exception” as the theoretical underpinnings for this es
Aim: To investigate the prevalence of general and back pain in children with cerebral palsy and the relationships between scoliosis and back pain. Methods: Cross-sectional register study based on data from the Swedish Cerebral Palsy Follow-Up Programme. Descriptive analyses and logistic regression to regress age, sex, gross motor function, windswept, hip extension and source of report on the prese
J-wave pattern has been recognized as an arrhythmic risk marker, particularly in myocardial infarction patients. Mechanisms underlying J-wave development in ischemia remain unknown. In myocardial infarction model, we evaluated activation time delay as a prerequisite of J-wave appearance and predictor of ventricular fibrillation. Body surface ECGs and myocardial unipolar electrograms were recorded
Objective To compare several methods of missing data imputation for function (Health Assessment Questionnaire) and for disease activity (Disease Activity Score-28 and Clinical Disease Activity Index) in rheumatoid arthritis (RA) patients. Methods One thousand RA patients from observational cohort studies with complete data for function and disease activity at baseline, 6, 12 and 24 months were sel
The level of extracellular calcium has been demonstrated to regulate important physiological processes like cell growth and apoptosis. We demonstrate that in the bladder cancer cell line RT4, an increased extracellular calcium level induces apoptosis and that the HER1 receptor functions as a cell survival factor and delays apoptosis. After 12 h of calcium treatment (10 mM) apoptosis was detected i
The six planets of the Kepler-11 system are the archetypal example of a population of surprisingly low-density transiting planets revealed by the Kepler mission. We have determined the fundamental parameters and chemical composition of the Kepler-11 host star to unprecedented precision using an extremely high-quality spectrum from Keck-HIRES (R ≃ 67,000, S/N per pixel at 600 nm). Contrary to previ
To determine the impact of a family history of the common form of type 2 diabetes and the phenotype of the proband on anthropometric and metabolic variables in normoglycemic first degree relatives, we studied 2100 first degree relatives of patients with the common form of type 2 diabetes (FH+) and 388 subjects without a family history of diabetes (FH-). All subjects participated in an oral glucose
