BACKGROUND Breast fibroadenomata (FAD) are the most common benign lesions in women. For palpable lesions, there are currently three standard treatment options: reassurance (with or without follow-up), vacuum-assisted mammotomy (VAM) or surgical excision. High-intensity focused ultrasound (HIFU) ablation has been used in the treatment of FAD. The drawback of HIFU is its prolonged treatment durat...

OBJECTIVE To assess the transactive response DNA-binding protein 43 (TDP-43) burden in familial forms of Alzheimer disease (FAD) and Down syndrome (DS) to determine whether TDP-43 inclusions are also present. DESIGN Using standard immunohistochemical techniques, we examined brain tissue samples from 42 subjects with FAD and 14 with DS. RESULTS We found pathological TDP-43 aggregates in 14.0...

The increasing presence of genetic neurodevelopmental disorders (NDDs) results in greater demands for counseling. Many studies focus on the characteristics patients, but less family functioning. aim this study is to objectify parental stress and its relationship with child environmental factors across several syndromes. 56 individuals NDD participated: 24 Kleefstra Syndrome, 13 Koolen-de Vries ...

The gene encoding the Amphibacillus xylanus flavoprotein has been cloned into pTTQ18 and overexpressed in Escherichia coli. The recombinant enzyme has been purified to homogeneity yielding 15 mg of pure enzyme/liter of cell culture. Recombinant flavoprotein is fully active and has an absorption spectrum identical to that of the enzyme purified from A. xylanus. The N-terminal sequence analysis a...

Sarcosine oxidase from Arthrobacter sp. TE1826 (SoxA) tightly binds with the coenzyme flavin adenine dinucleotide (FAD). The amino-terminal region of this enzyme was recognized as a part of the FAD-binding domain by homology search analysis. Comparison with other structurally well-known flavoproteins suggested that the aspartate residue at position 35 (D-35) and the motif sequence (six residues...

The phosphate- and oxygen-dependent pyruvate oxidase from Lactobacillus plantarum is a homotetrameric enzyme that binds 1 FAD and 1 thiamine diphosphate per subunit. A kinetic analysis of the partial reactions in the overall oxidative conversion of pyruvate to acetyl phosphate and CO2 shows an indirect activation of the thiamine diphosphate by FAD that is mediated by the protein moiety. The rat...

Riboflavin (Rf) and its metabolic analogs flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) are essential for normal cellular growth and function. Their intracellular transport is regulated by the riboflavin carrier protein (RCP), which has been shown to be over-expressed by metabolically active cancer cells. Therefore, FAD-decorated ultrasmall superparamagnetic iron oxide nanop...

2-Aminobenzoyl-CoA monooxygenaselreductase catalyzes both monooxygenation and hydrogenation of anthraniloyl-CoA. Its reactivity with 11 substrate analogs has been investigated. Only 2-aminobenzoylCoA (anthraniloyl-CoA) in its normal and deuterated (5-'H) form is a full substrate, and only traces of 2hydroxybenzoyl-CoA (salicyloyl-CoA) are probably monooxygenated but not hydrogenated. The purifi...

Mycobacterium tuberculosis FprA (flavoprotein reductase A) is an NAD(P)H- and FAD-binding reductase that is structurally/evolutionarily related to adrenodoxin reductase. Structural analysis implicates Arg(199) and Arg(200) in interactions with the NADP(H) 2'-phosphate group. R199A, R200A and R199A/R200A mutants were characterized to explore the roles of these basic residues. All mutations aboli...

Fatty acid desaturases (FADs) introduce double bonds into the hydrocarbon chains of fatty acids to produce unsaturated fatty acids, and therefore play a critical role in plant development and acclimation to environmental stresses. In this study, 23 full-length FAD genes in cucumber (Cucumis sativus L.) were identified through database searches, including three CsFAB2 genes, two CsFAD2 genes, fo...
