Vegetative cells of Myxococcus xanthus (strain FB) were induced to form myxospores by the glycerol induction technique. Several structural changes took place in the peptidoglycan during myxospore formation. The percent of the peptidoglycan comprised of monomer (disaccharide peptide) decreased from about 20% to approximately 7%. The proportion of the total diaminopimelic acid possessing a free a...

A novel method to calculate fB on the lattice is introduced, based on the study of the dependence of finite size effects upon the heavy quark mass of flavoured mesons and on a non–perturbative recursive finite size technique. We avoid the systematic errors related to extrapolations from the static limit or to the tuning of the coefficients of effective Lagrangian and the results admit an extrap...

Fumonisin B(1) (FB(1)), a mycotoxin produced by Fusarium verticillioides present on corn and corn-based products, causes species- and organ-specific diseases. The hepatotoxic effects of FB(1) in mice have been closely correlated with the accumulation of free sphinganine, a marker for ceramide synthase inhibition, and reduced biosynthesis of more complex sphingolipids. It has been shown that FB(...

Fibroblasts (Fb) from patients with sarcoidosis (SA) and hypersensitivity pneumonitis (HP) exhibited a lower proliferative capacity compared with Fb obtained from control (CO) and diffuse interstitial fibrosis patients (DIF). Proliferation of Fb from SA or lip patients was suppressed by autologous LPS-stimulated alveolar macrophages (AM) supernatants but not by those from CO patients. Similarly...

BACKGROUND Guidelines support endoscopic removal of certain gastric FB and all FB lodged in the esophagus. We aim to report our experience on endoscopic foreign bodies (FB) removal in order to aid in the formation of future guidelines regarding this subject. METHODS Retrospective analysis of one hundred forty-four cases of FB removal involving 43 patients who underwent esophagogastroduodenosc...

The reaction of the primary amine of fumonisin B(1) (FB(1)) with glucose was hypothesized to detoxify this mycotoxin. Eighty 10-day-old female F344/N rats were injected intraperitoneally with diethylnitrosamine (DEN; 15 mg/kg of body weight). At 4 weeks of age, the weaned rats were randomly assigned to one of four treatment groups with 20 rats each. At 9 weeks of age, four rats from each treatm...

BACKGROUND Incomplete spinal cord injury (iSCI) leads to motor and sensory deficits. Even in ambulatory persons with good motor function an impaired proprioception may result in an insecure gait. Limited internal afferent feedback (FB) can be compensated by provision of external FB by therapists or technical systems. Progress in computational power of motion analysis systems allows for implemen...

BACKGROUND Compared to positive fluid balance (FB), negative FB is associated with improved clinical outcomes in critically ill patients. However, as to whether achieving more negative FB can further improve outcomes has not been investigated. This study aimed to investigate whether more negative FB and restricted fluid intake were associated with improved outcomes in critically ill patients. ...

Microgenetic methods were used to document young children’s (N = 36; M age = 3;5) acquisition of false belief (FB) understanding and investigate developmental mechanisms. A control group received no experience with FB; 2 other groups received microgenetic sessions designed to promote FB understanding. Over consecutive weeks, microgenetic groups received implicit feedback about their performance...

BACKGROUND Fumonisin B(1) (FB(1)) is a mycotoxin produced by a common fungal contaminant of corn. Ingestion of FB(1)-contaminated food is associated with increased risk for neural tube defects (NTDs). FB(1) induces NTDs in inbred LM/Bc mice. FB(1) inhibits ceramide synthase in de novo sphingolipid biosynthesis, resulting in accumulation of sphinganine and sphinganine-1-phosphate (Sa1P). Sa1P fu...
