Publication date: Available online 28 May 2019Source: Journal of Pharmaceutical and Biomedical AnalysisAuthor(s): Neeraj Kumar Saini, Suresh P Sulochana, Vinay Kiran, Sadanand Rangnathrao Mallurwar, Wolfgang Ritcher, Nuggehally R Srinivas, Ramesh MullangiAbstractA selective, sensitive and rapid mice dried blood spot (DBS) method has been developed and validated for the simultaneous quantification of bendamustine (BM) and γ-hydroxy-bendamustine (HBM) as per regulatory guidelines using an LC-MS/MS. Quality control, calibration curve and study sample DBS cards were sonicated with 5% formic acid in water before extraction with ethyl acetate enriched with internal standard. The organic layer was evaporated and residue was reconstituted in 0.1% formic acid in acetonitrile for LC-MS/MS analysis. Chromatographic resolution of both analytes (BM and HBM) and the I.S. (loperamide) was achieved on an Atlantis dC18 column using 0.2% formic acid:acetonitrile (25:75, v/v) as an eluant delivered at a constant flow-rate of 0.5 mL/min. The total chromatographic run time was 3.2 min. The MS/MS ion transitions monitored were m/z 358.0 → 228.0, 374.0 → 338.0 and 477.0 → 210.0 for BM, HBM and the I.S, respectively. The assay was linear in the range of 5.65-2544 ng/mL for both BM and HBM. The within-run and between-run accuracy and within-run and between-run precision were in the range of 0.96-1.00 and 1.36-9.94%, respectively for BM; 0.88-1.03 and 4.57-11....

We investigated the effects of aqueous extract (AE) and methanolic extract (ME) of Helichrysum odoratissimum for reducing CP-induced reproductive toxicity in male rats.MethodsIn addition to a normal control (group 1), drugs or v...

This study used Oswestry Disability Index (ODI)-self-comparison and showed that acupuncture treatments for lumber disc herniation and sciatica demonstrated significant improvement in long term clinical outcomes. A total of 112 lumbar disc herniation and sciatica cases were treated with electric acupuncture for pain relief and function improvement from July 1998 to December 2006.ResultsAll the 112 cases filled out the ODI forms prior to receiving treatment. Among the 112 patients, 23 of them did not finish the 6-week treatments. 89 cases were evaluated with ODI after 6-week acupuncture treatments. Of those 89 cases, 67 case...

ConclusionIn a cohort of 40 older adults with newly diagnosed multiple myeloma, three frailty indices have differing approaches to operationalizing frailty resulting, in different patients being categorized as frail. Little agreement existed between the models. Further studies are needed to explore the utility of these models in predicting treatment toxicity and prognosis.
