The dichloromethane fraction of Stemona tuberosa Lour

Introduction Human medullary thyroid carcinoma (MTC) a malignant neoplasm derived from parafollicular cells represents about 5%–10% of thyroid tumors (Vitale et al 2001) It may occur sporadically in a familial form without associated endocrinopathies or combined with other endocrinopathies as multiple endocrine neoplasia type 2A or 2B with autosomal dominant inheritance

ChemTeam: Converting between ppm and molarity

Note that the solution density is assumed to be 1 00 g/mL This is the common practice in ppm calculations 2) Convert to ppm by multiplying numerator and denominator by 1000: 0 4008 g / 1000 g of solution times 1000/1000 = 400 g / 1 000 000 g of solution The answer is 400 ppm Notice how the weight for calcium ion only is used
