Clostridioides difficile water-soluble zwitterionic lipoteichoic acid wsPS-III: structure, synthesis, and immunogenicity

Clostridioides difficile polysaccharides (PSs) represent useful tools for the study of C. difficile pathogenesis. Water-soluble PS-I (pentaglycosyl-phosphate repeats) and PS-II (hexaglycosyl-phosphate repeats) and phenol-soluble lipoteichoic acid (LTA)…

Severe thrombocytopenia is associated with arterial thrombotic manifestations in antiphospholipid syndrome: a two-center cohort study

ObjectiveThrombocytopenia in APS is often regarded primarily as a bleeding-related manifestation, but the relationship between platelet-count severity and thrombotic manifestations remains uncertain. We evaluated the association between severe thromboc…

Evaluating disease activity scores and CBC-derived indices in relation to osteoporosis risk in rheumatoid arthritis: a cross-sectional analysis

BackgroundOsteoporosis (OP) is a frequent comorbidity in rheumatoid arthritis (RA). This study compared the performance of RA disease-activity scores with complete blood count (CBC)-derived indices for identifying prevalent OP.MethodsWe retrospectively…

Pseudomonas aeruginosa-derived volatile organic compounds modulate host immunity to disrupt airway mucus homeostasis

Chronic pulmonary diseases, including cystic fibrosis, chronic obstructive pulmonary disease, and chronic bronchitis, as well as ventilator-associated pneumonia, are characterized by persistent infection of mucus-laden airways. Pseudomonas aeruginosa (…

Micro- and nanoplastics remodel the autophagy-lysosomal axis and mitochondrial function in primary human monocytes

BackgroundMicro- and nanoplastics (MNPs) are increasingly detected in human tissues, raising concerns regarding their potential impact on immune cell function. Monocytes are among the first immune cells to encounter and internalize these particles. How…

A hybrid high activity aware framework integrating graph attention network and transformer for half maximal inhibitory concentration prediction

IntroductionTyrosine kinase inhibitors targeting the c-KIT receptor are pivotal in the targeted therapy of malignancies such as gastrointestinal stromal tumors (GIST). The bioactivity of these inhibitors is typically quantified by the half-maximal inhi…

Malignancies in patients with inborn errors of immunity: insights from 20-years of clinical experience in Qatar

IntroductionInborn errors of immunity (IEI) are associated with an increased risk of malignancy; however, the spectrum, timing, and outcomes of cancer across different IEI subgroups remain incompletely characterized.MethodologyWe conducted a retrospect…
