Granulomatous Mastitis: Comparison of Novel Treatment of Steroid Injection and Current Management.

Background: Granulomatous mastitis (GM) is a rare entity of benign origin. Multiple treatment strategies, including surgical procedures, can have sequelae of recurrence, nonhealing wounds, and protracted pain. Even after GM is diagnosed, the best management strategy remains controversial.

Age and apolipoprotein E ε4 effects on neural correlates of odor memory.

Alzheimer's disease (AD) affects 5.4 million Americans. Evidence suggests that individuals who are positive for the apolipoprotein E (ApoE) ε4 allele are at higher risk for developing the disease.

Altered substrate specificity in flavocytochrome b2: structural insights into the mechanism of L-lactate dehydrogenation.

Flavocytochrome b(2) from Saccharomyces cerevisiae is a l-lactate/cytochrome c oxidoreductase belonging to a large family of 2-hydroxyacid-dependent flavoenzymes. The crystal structure of the enzyme, with pyruvate bound at the active site, has been determined [Xia, Z.-X.

Expression, purification and characterisation of a Bacillus subtilis ferredoxin: a potential electron transfer donor to cytochrome P450 BioI.

The fer gene from Bacillus subtilis has been subcloned and overexpressed in Escherichia coli and the protein (Fer) purified to homogeneity. N-Terminal sequencing and mass spectrometry indicate that the initiator methionine is removed from the protein and that the molecular mass is 8732 Da consistent with that deduced from the gene sequence. Amino-acid sequence comparisons indicate that Fer is a ferredoxin containing a 4Fe-4S cluster.
