Strawberry plants exhibiting symptoms of stunting and abnormally small leaves were observed in production fields in central Florida, USA. Since the symptoms were suggestive of phytoplasma infection, plants were assayed for presence of phytoplasma by PCR amplification of 16S rDNA and ribosomal protein (rp) gene sequences. Amplification of phytoplasma-specific DNA sequences by PCR indicated infec...

Several reproducibility probability (RP)-estimators for the binomial, sign, Wilcoxon signed rank and Kendall tests are studied. Their behavior in terms of MSE is investigated, as well as their performances for RP-testing. Two classes of estimators are considered: the semi-parametric one, where RP-estimators are derived from the expression of the exact or approximated power function, and the non...

BACKGROUND Recently, three prospective randomized trials have shown that adjuvant radiotherapy (ART) after radical prostatectomy for the patients with pT3 and/or positive margins improves biochemical progression-free survival and local recurrence free survival. But, the optimal management of these patients after radical prostatectomy is an issue which has been debated continuously. The object o...

Purpose Active surveillance (AS) is a treatment option for men with very low–risk prostate cancer (PCa); however, favorable outcomes achieved for men in AS are based on cohorts that under-represent African American (AA) men. To explore whether race-based health disparities exist among men with very low–risk PCa, we evaluated oncologic outcomes of AA men with very low–risk PCa who were candidate...

CONTEXT Radical prostatectomy (RP) approaches have rarely been compared adequately with regard to margin and perioperative complication rates. OBJECTIVE Review the literature from 2002 to 2010 and compare margin and perioperative complication rates for open retropubic RP (ORP), laparoscopic RP (LRP), and robot-assisted LRP (RALP). EVIDENCE ACQUISITION Summary data were abstracted from 400 o...

pregabalin (prg) is a new antiepileptic drug and aceclofenac (ace) is a potent non-steroidal anti-inflammatory drug. these drugs in combination are used for treatment of partial seizures and neuropathic pains. a simple and precise assay method by rp-hplc was developed and validated for estimation of prg and ace in acenac-n tablet. analyses of commercial tablet, acenac-n were performed using jas...

low molecular weight organic acids are most predominant in apple juice among these components fumaric acid was not exceed more than 5 ppm. it was thought that the hplc is the best method of the determination of organic acids in the apple juice. in this study, chromatographic separation of organic acids of apple juice was obtained by preparing a sample and by applying them to acid phase for extr...

a simple and reliable stability-indicating rp-hplc method was developed and validated for analysis of adefovir dipivoxil (adv).the chromatographic separation was performed on a c18 column using a mixture of acetonitrile-citrate buffer (10 mm at ph 5.2) 36:64 (%v/v) as mobile phase, at a flow rate of 1.5 ml/min. detection was carried out at 260 nm and a sharp peak was obtained for adv at a reten...

an environmentally benign rp-hplc approach for rapid analysis of glibenclamide in pure form, developed nanoemulsion and commercial tablets was developed and validated in present investigation. the green chromatographic identification was performed on lichrosphere 250 x 4.0 mm rp c8 column having a 5µm packing as a stationary phase using a combination of ethanol: methanol (50:50 % v/v) as a mobi...

The use of a prescriptive fitting approach for hearing aid selection has been a common practice for the past 60-70 years. While there are prescriptive approaches that have been validated, in recent years it has become popular to deviate from these validated methods and use manufacturers' proprietary algorithms, which in many cases are significantly different. This research review was designed t...
