Moreover, since red lentil is dehulled prior to consumption, an opportunity exists at this point to fortify lentil with Fe. Thus, in the present study, lentil was Fe-fortified (using a fortificant Fe concentration of 2800 µg g) and used in 30 traditional Bangladeshi meals with broad differences in concentrations of iron, phytic acid (PA), and relative Fe bi...

Response to BRAF/MEK Inhibition After Progression With BRAF Inhibition in a Patient With Anaplastic Pleomorphic Xanthoastrocytoma.

Pleomorphic xanthoastrocytoma (PXA) is a rare primary central nervous system tumor which frequently harbors mutations in BRAF. Anaplastic PXA follow a more aggressive course than their nonanaplastic counterparts. We present the case of an anaplastic PXA initially treated with the BRAF inhibitor vemurafenib. After progression of disease the MEK inhibitor trametinib was added to the regimen leading to radiographic improvement. The rationale for combined BRAF and MEK inhibition in PXA is reviewed.
