Though it's too early to tell exactly how such exercises might find their way into standard substance
abuse treatment, the findings suggest that taking a few minutes for "orchestrated positive experiences" may be something everyone should consider, says the study's lead author, Bettina Hoeppner, PhD, a senior research scientist at MGH s Recovery Research Institute.
Regression equation Curcumin 7 = 9096.4% - 20.331 Desmethoxycurumin 7 = 9194.2% - 5.6895 Bisdesmethoxycurum 7 = 8601.1% + 2.2162 Standard substance

Linearity of the proposed TLC method was determined by plotting peak area (A)[AU]versus concentration (x) of the proper standard substance
: hydrocortisone acetate or lidocaine hydrochloride respectively, in [micro]g-[spot.sup.-1] (Table 2).
Unlike many standard substance
use treatment programs, PHPs utilize a large drug test panel which typically includes over 20 substances, with even more expanded drug panels available for use as needed (DuPont et al.

The difference is thatWestern medical practices require the side effects of medicinal substances to be clearly identified, explains Wei Lixin, a member of the Professional Commission of Ethnic Medicines and Traditional Chinese Medicines Standard Substances
under the Chinese Pharmacopoeia Commission.
Four standard substances
, certified for both density value and refractive index, can be used to certify or verify density and refractive index instruments or combined measurement systems.
Table 4 gives the linear regression equation, linear range, limit of quantitation (LOQs), and limit of detections (LODs) of eight standard substances
