Abstract
Quantification of ultra-trace analytes in complex biological samples using micro-solid-phase extraction followed by direct detection with internal extractive electrospray ionization mass spectrometry (μSPE-iEESI-MS) was demonstrated. 1-Hydroxypyrene (1-OHP) and papaverine at attomole levels in human raw urine samples were analyzed under negative and positive ion detection mode, respectively. The μSPE was simply prepared by packing a disposable syringe filter with octadecyl carbon chain (C18)-bonded micro silica particles, which were then treated as the "bulk sample" after the analytes were efficiently enriched by the C18 particles. Under the optimized experimental conditions, the analytes were readily eluted by isopropanol/water (80/20, V/V) at a high voltage of ± 4.0 kV, producing analyte ions under ambient conditions. The limit of detection (LOD) was 0.02 pg/L (9.2 amol) for 1-hydroxypyrene and 0.02 pg/L (5.9 amol) for papaverine. The acceptable linearity (R2 > 0.99), signal stability (RSD ≤ 10.7%), spike recoveries (91-95%), and comparable results for real urine samples were also achieved, opening up possibilities for quantitative analysis of trace compounds (at attomole levels) in complex bio-samples.

Abstract
A method has been developed for extracting poppy alkaloids from oily matrices, specifically lipid residues associated with archaeological ceramics. The protocol has been applied to fresh and artificially aged poppyseed oil and to residue from a Late Bronze Age Cypriot juglet in the collections of the British Museum. The juglet is of a type that has been linked with ancient trade in opium due to its poppy-head shape and wide distribution; it is a rare example of an intact vessel with contents sealed inside. Bulk analysis of the residue by GC-EI-MS and pyGC-EI-MS indicated a degraded plant oil and possible presence of papaverine. Analysis of the alkaloid extracts by HPLC-ESI-MS using both triple quadrupole and FTICR mass spectrometers detected the five primary opium alkaloids in fresh poppyseed oil and papaverine in most of the aged samples. Papaverine and thebaine were detected in the juglet residue, providing the first rigorous chemical evidence to support a link between this vessel type and opium, or at least poppies. The association of opium with oil raises new questions about the ancient purpose of the commodities within these vessels, and the low levels (ng g-1) of opiates detected in this unusually well-preserved residue shed doubt on the scope for their detection in more fragmentary ceramic remains (potsherds). Papaverine was found to exhibit challenging carryover behaviour in all the analytical methods used in this study. The phenomenon has not been reported before and should be considered in future analyses of this analyte in all application areas.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is a common cause of discomfort and morbidity worldwide. However, information on determinants of GERD from large-scale studies in low- to medium-income countries is limited. We investigated the factors associated with different measures of GERD symptoms, including frequency, patient-perceived severity, and onset time. METHODS We performed a cross-sectional analysis of the baseline data from a population-based cohort study of ∼ 50,000 individuals in in Golestan Province, Iran. GERD symptoms in this study included regurgitation and/or heartburn. RESULTS Approximately 20% of participants reported at least weekly symptoms. Daily symptoms were less commonly reported by men, those of Turkmen ethnicity, and nass chewers. On the other hand, age, body mass index, alcohol drinking, cigarette smoking, opium use, lower socioeconomic status, and lower physical activity were associated with daily symptoms. Most of these factors showed similar associations with severe symptoms. Women with higher BMI and waist to hip ratio were more likely to report frequent and severe GERD symptoms. Hookah smoking (OR 1.34, 95% CI 1.02-1.75) and opium use (OR 1.70, 95% CI 1.55-1.87) were associated with severe symptoms, whereas nass chewing had an inverse association (OR 0.87, 95% CI 0.76-0.99). After exclusion of cigarette smokers, hookah smoking was still positively associated and nass chewing was inversely associated with GERD symptoms (all frequencies combined). CONCLUSION GERD is common in this population. The associations of hookah and opium use and inverse association of nass use with GERD symptoms are reported for the first time. Further studies are required to investigate the nature of these associations. Other determinants of GERD were mostly comparable to those reported elsewhere.

Abstract
Heroin is one of the most dangerous abused drugs in the world. Tramadol is an additive recently found at high concentration levels in street heroin seizures in Egypt. This substance could affect the usual analytical method for the detection of heroin and metabolites, as well as the pharmacokinetic and disposition of single analytes. One shortfall regarding this issue is present in the literature. This study describes a validated, simple, sensitive and selective method to determine tramadol, O-desmethyltramadol, 6-acetylmorphine and free morphine in the blood, brain, liver and kidney of Wistar rats, intraperitoneally treated with a combination of heroin and tramadol (10 and 70 mg/kg, respectively) using liquid-liquid extraction and gas chromatography-mass spectrometry detection. The calibration curves of tramadol, O-desmethyltramadol and 6-acetylmorphine in blood were linear in the concentration range from 25-5,000 ng/mL and morphine was found in the concentration range 50-5,000 ng/mL. The analytes were detected in all tested matrices, except 6-acetylmorphine, which was not detected in liver. The highest concentrations of tramadol and O-desmethyltramadol were observed in kidney (22,9381 and 28,498 ng/g), while 6-acetylmorphine and morphine were found at the highest levels in brain (3,280 and 3,899 ng/g, respectively). The present method is simple, rapid and sensitive and can be used to study the pharmacokinetics, disposition and interaction of these drugs in several animal models.

Abstract
A new flow injection chemiluminescence (CL) system was used for the determination of noscapine. This technique is based on the reduction effect of noscapine on the Ru(phen)3(3+), which is produced by reaction between Ru(phen)3(2+) and acidic Ce(IV) solutions, and this rapid reduction produces strong CL. Calibration plots were linear over the range of 3.0 x 10(-7) - 2.0 x 10(-6) mol L(-1) and 2.0 x 10(-6) - 2.0 x 10(-4) mol L(-1). The CL intensity was so high, that it is able to produce a detection limit of 6.6 x 10(-8) M noscapine (3sigma). The relative standard deviation of 2.0 x 10(-6) M noscapine was 1.0% (n=10). The proposed method was successfully applied for the flow injection determination of noscapine in cough and Tonin syrup samples. The results of real sample analyses show good recovery percentages (97.3-102.4%). The minimum sampling rate was 100 samples per hour.

Abstract
Based on aqueous two-phase system (ATPS) of poly(ethylene glycol) (PEG)-(NH4)2SO4, a simple pretreatment approach was developed for the extraction and determination of papaverin in pericarpium papaveris. The influence factors on phase behavior of the ATPS and partition behavior of papaverin was investigated, and partition mechanism based on the hydrophobic interaction between PEG and analyte molecules was proposed. Under the optimal conditions, the extraction efficiencies for papaverin were 93-96%, and the recoveries of the added standard were 97-106% with relative standard deviations of 1.8-2.5%. Combined with a high-performance liquid chromatography (HPLC) method, this extraction technique has been successfully applied to the determination of papaverin in pericarpium papaveris with the detection limit of 2 ng mL(-1) and the linear range of 0.10-10 microg mL(-1). Compared with the conventional liquid-liquid extraction or solid-phase extraction, this method was more environmentally benign, more cost effective and much simpler due to the direct injection of the upper phase into HPLC system.

Abstract
In Iran, opium is smoked for pleasure or as a medication by some people. It is a complex mixture of 40 different alkaloids, including morphine and codeine along with many impurities. Although it is well established that opioids or tobacco affect many physiological functions in humans, to our knowledge there has been no specific study looking at these effects in opium smokers. To assess that, we investigated the circulating levels of prolactin, TSH, LH, FSH and testosterone in male opium smokers who also smoke cigarettes (n=23, aged 28.4+/- 4.1 years), and comparing this with the corresponding values for nicotine abusers (n=12, 15-25 cigarettes/day) or a healthy control group (n=20) of the same age. Our results showed that 86.96% of the opium-dependent and 41.67 % of the nicotine-dependent group displayed high prolactin values (p<0.002). In addition, there was a positive correlation between the dose of opium and the plasma prolactin level of opium dependents (p=0.748, p<0.001). Low FSH was detected in 43.48% of the opium smokers and 50% of the cigarette smokers (p<0.001) with normal LH and testosterone levels. TSH of the opium smokers was also lower than that of the other two groups (p<0.002). In conclusion, the present data indicate that chronic opium and cigarette smoking may synergistically influence pituitary hormone production through the effects on neuropeptides produced either locally or systemic.

Abstract
The new ionization method, called surface-activated chemical ionization (SACI), was employed for the analysis of fives drugs (morphine, codeine, 6-monoacetylmorphine (6-MAM), benzoylecgonine and cocaine) by ion trap mass spectrometry. The results so obtained have been compared with those achieved by using atmospheric pressure chemical ionization (APCI), no-discharge-APCI and electrospray ionization (ESI) clearly showing that SACI is the most sensible one mainly due to the high ionization efficiency and the lower chemical noise. The performance of SACI in terms of sensitivity and linearity was compared with the sensitivity and linearity obtained using APCI, no-discharge-APCI and ESI, showing that the new SACI approach gives rise to the best results. Then, SACI was used to analyze morphine, codeine, 6-MAM, benzoylecgonine and cocaine in urine samples. After the optimization of the instrumental parameters for a mixture of the standard compounds, eight urine samples were analyzed. They were strongly diluted (1 : 20 and 1 : 100) in order to prevent the chromatographic column damage due to the matrix composition. Furthermore, the diluted urine samples were directly analyzed, without pretreatment, through LC-MS and LC-MS/MS, and the obtained results are reported.

Abstract
A highly selective immunoaffinity column was obtained by coupling anti-papaverine polyclonal antibodies to CNBr-activated Sepharose 4B. It was found that the coupling efficiency and performance of the immunoaffinity column were greatly improved by prolonging the coupling reaction time from 3 h at 20 degrees C with shaking to incubation overnight at 4 degrees C after the 3 h shaking reaction. The pH and ionic strength were observed to be the most important factors that influence the binding of papaverine to the immunoaffinity column. Using 0.01 mol/L phosphate buffered saline (PBS, pH 8.3) and methanol-water (80:20, v/v) as the loading and eluting solutions, respectively, papaverine was first retained on the column and then quantitatively eluted out with a mean recovery of 86% at a loading concentration of 1 microg/mL. When applied to real samples of pericarpium papaveris and food products, the established immunoaffinity column showed high efficiency in removing the matrix interferences in the samples and satisfactory recovery results were obtained. The method was useful for extraction and purification of papaverine from related samples.

Abstract
A simple and sensitive direct injection chromatographic procedure is developed for the determination of heroin, two of its metabolites (morphine and 6-monoacetylmorphine (6-MAM)), and benzoylecgonine (a metabolite of cocaine) in serum samples. The proper resolution of the four substances is obtained with a chemometrics approach, where the retention is modelled as a first step using the retention factors obtained in a limited number of mobile phases. Afterwards, an optimisation criterion that takes into account the position and shape of the chromatographic peaks is applied. The mobile phase selected to carry out the analysis was 0.1 mol L(-1) SDS-4% (v/v) butanol buffered at pH 7, in which the separation is performed in less than 18 min. The limits of quantification were in the 17-36 ng mL(-1) range. Intra- and inter-day assay accuracy and precision (below 3%) were obtained following ICH guidelines. The method developed was applied to the determination of the drugs studied in serum samples with good recoveries (90-104%). Serum samples from subjects that have been ingested cocaine and heroin were also analysed. The samples were injected directly in the chromatographic system without any pretreatment.
