Cholera epidemics are caused by Vibrio cholerae serogroups O1 and O139, whereas strains collectively known as non-O1/non-O139 V. cholerae are found in cases of extraintestinal infections and bacteremia. The mechanisms and factors influencing the occurrence of bacteremia and survival of V. cholerae in normal human serum have remained unclear. We found that naturally occurring IgG recognizing V. cho
Background: Hereditary thrombocytopenias constitute a genetically heterogeneouscause of increased bleeding. We report a case of a 17-year-old boy suffering fromsevere macrothrombocytopenia throughout his life. Whole genome sequencing revealed the presence of two compound heterozygous variants in GNE encoding the enzyme UDP-N-acetyl-glucosamine-2-epimerase/N-acetylmannosamine kinase, crucial for si
Protein lysine acetylation is known to regulate multiple aspects of bacterial metabolism. However, its presence in mycobacterial signal transduction and virulence-associated proteins has not been studied. In this study, analysis of mycobacterial proteins from different cellular fractions indicated dynamic and widespread occurrence of lysine acetylation. Mycobacterium tuberculosis proteins regulati
Antibody binding sites provide an adaptable surface capable of interacting with essentially any molecular target. Using CDR shuffling, residues important for the assembly of mucin-1 specific paratopes were defined by random recombination of the complementarity determining regions derived from a set of mucin-1 specific clones, previously selected from an antibody fragment library. It was found that
Background--Both the adrenergic and renin-angiotensin systems contribute to orthostatic circulatory homeostasis, which is impaired in postural orthostatic tachycardia syndrome (POTS). Activating autoantibodies to the α1-adrenergic and β1/2-adrenergic receptors have previously been found in sera from patients with POTS. We hypothesized that patients with POTS might also harbor activating autoantibo
Numerical weather prediction models are increasing in resolution and becoming capable of explicitly representing individual convective storms, but we do not yet know if it is the improved resolution that is leading to better forecasts.
From a population of 8918 farmers, 237 were selected whose consumption of locally produced foods was high. The subjects' water sources, private wells, were of different degrees of acidity. Significant associations between pH (median 6.7, range 4.7-8.6) of the drinking water and element concentrations were found. The correlation was negative for aluminium (Al; median 0.07 mumol/l), cadmium (Cd; 0.4
Cell-based therapies hold great promise in re-establishing organ function for many diseases, including untreatable lung diseases such as idiopathic pulmonary fibrosis (IPF). However, many hurdles still remain, in part due to our lack of knowledge about the disease-driving mechanisms that may affect the cellular niche and thereby possibly hinder the function of any transplanted cells by imposing th
Immune checkpoint inhibitors (ICI) targeting programmed cell death‐1 or its ligand (PD‐ L1) have improved outcomes in non‐small cell lung cancer (NSCLC). High tumor PD‐L1 expression, detected by immunohistochemistry (IHC) typically on formalin‐fixed paraffin‐embedded (FFPE) histological specimens, is linked to better response. Following our previous investigation on PD‐L1 in cytological samples, t
The interaction of protein S with membranes and subsequent combination with complement C4b-binding protein (C4BP) was studied. Protein S interacted with phospholipid vesicles in a calcium-dependent manner typical of other vitamin K-dependent proteins. Association of C4BP with protein S showed no apparent selectivity for membrane-bound or solution phase protein S. When bound to the membrane, the pr
Neutrophils play a crucial role in host defense. However, neutrophil activation is also linked to autoimmune diseases such as systemic lupus erythematosus (SLE), where nucleic acid-containing immune complexes (IC) drive inflammation. The role of Toll-like receptor (TLR) signaling in processing of SLE ICs and downstream inflammatory neutrophil effector functions is not known. We observed that TLR7/
BACKGROUND: Artificial intelligence (AI) systems performing at radiologist-like levels in the evaluation of digital mammography (DM) would improve breast cancer screening accuracy and efficiency. We aimed to compare the stand-alone performance of an AI system to that of radiologists in detecting breast cancer in DM.METHODS: Nine multi-reader, multi-case study datasets previously used for different
Using a novel experimental approach based on near-infrared femtosecond absorption spectroscopy, we have determined the energy of the S-1 state of the carotenoid spheroidene. The energy of this state is 13 400 +/- 90 cm(-1) at both 293 and 186 K, showing that there is no temperature-induced shift of the S-1 level. A discrepancy of about 800 cm(-1) between the S-1 energy determined here and that obt
Popular Abstract in Swedish Melamisufism (melamet) fanns i olika delar av Osmanska riket. Den sista perioden, då melamirörelsen var särskilt märkbar, tar sin början i slutet av 1800-talet, och då med en koncentration i den europeiska delen av det osmanska riket (Rumeli). Detta hänger samman med att melamiordens huvudschejk Sejjid Muhammed Nur el-Arebi, bodde och var verksam där under denna tid. MeThis dissertation focuses on Melami history in Bosnia with emphasis on the 20th century. The well-known Melami master Hajrullah Abdurahmanovic (d. 1965) in this study becomes an exponent for changes in the political and social role of religion in course of the 20th century. The purpose of this research is to describe and analyze the theology of the Melami movement in the environments created by su
The polymerase chain reaction techniques was introduced for the intratypic characterization of Poliovirus. Primers were used only to promote the amplification of the Sabin vaccine strains proved by electrophoretic run of the amplified DNA products (Sabin 1-97 pb, Sabin 2-71 pb, Sabin 3-44 pb) and whose specificity was satisfactorily verified. 23 Cuban poliovirus strains isolated and identified at
Sera from 25 metastatic breast cancer patients and 25 healthy controls were subjected to affinity chromatography using immobilized galectin-1. Serum from the healthy subjects contained on average 1.2 mg per ml (range 0.7-2.2) galectin-1 binding glycoproteins, whereas serum from the breast cancer patients contained on average 2.2 mg/ml (range 0.8-3.9), with a higher average for large primary tumour
The past two decades have brought worrying increases in severe Streptococcus pyogenes diseases globally. To investigate and compare the epidemiological patterns of these diseases within Europe, data on severe S. pyogenes infections were collected through an EU FP-5 funded programme (Strep-EURO). Prospective population-based surveillance of severe S. pyogenes infection diagnosed during 2003 and 200
