Quantification of Ochratoxin A in 90 spice and herb samples using the ELISA method.

This study addressed the challenge of accurately detecting mycotoxins in herbs and spices, which have gained popularity as alternative medicines but pose health risks due to potential contamination. We used a competitive direct ELISA kit (Art No. 8610), Veratox for Ochratoxin, to quantify Ochratoxin A in the herb and spice samples. The samples were first prepared using solid-liquid extraction with 70% methanol. The resulting filtrate was then subjected to ELISA analysis. The results of the analysis were then further analyzed using principal component analysis (PCA). In this study, PCA was used to classify the concentration levels of Ochratoxin A based on various factors, such as the packaging type, country of origin, shelf life, and sample weight. The limits of detection (LOD) and quantification (LOQ) values indicate the lowest amount of Ochratoxin A that can be detected and quantified, respectively, with high accuracy and precision. The range of the LOD and LOQ values (0.43-0.58 µg/kg and 1.45-1.95 µg/kg, respectively) suggests that the method used was capable of detecting and quantifying Ochratoxin A in the herb and spice samples at different concentrations with a high degree of accuracy and precision. These results suggest that while most of the samples (73.33%) were below the maximum residue limit (MRL) for Ochratoxin A, a significant number of samples (26.67%) had concentrations of Ochratoxin A that were higher than the MRL. This highlights the importance of monitoring Ochratoxin A in herb and spice samples and ensuring the products are safe for consumption.

Knowledge about Medicine Use in Pregnancy: A National Study among Pharmacy Students in Jordan.

BACKGROUND: Knowledge of medication use during pregnancy presents a concern to pharmacists upon graduation since they will be responsible for drug-related inquiries and counselling pregnant women about their medications. The present study aimed to assess undergraduate senior pharmacy students' knowledge about medication use during pregnancy in Jordan. METHODS: A cross-sectional survey was conducted in Jordanian universities. A total of 409 senior pharmacy students participated in the study. RESULTS: The results found that the majority of the students (60.6%) did not have enough instruction on medications during pregnancy through their undergraduate study. Overall, only 2.5% of the participating students were considered to have good knowledge about medicine use during pregnancy and accordingly, the majority (52.6%) were not confident to recommend medicines for pregnant women in the future. In view of that, participating students suggested the addition of an obligatory course to the current curriculum. Students in public universities, Pharm.D. students, and those in their sixth year of study were more knowledgeable than others (P > 0.05). CONCLUSION: It was concluded that pharmacy students have low knowledge regarding medication use in pregnancy. The results call for a reassessment of the current pharmacy curriculum.

Design and synthesis of new 8-anilide theophylline derivatives as bronchodilators and antibacterial agents.

Theophylline derivatives have long been recognized as potent bronchodilators for the relief of acute asthma. Recently, it was found that bacterial infection has a role in asthma pathogenesis. The present work involves the design and synthesis of 8-substituted theophylline derivatives as bronchodilators and antibacterial agents. The chemical structures of these compounds were elucidated by IR, (1)H-NMR, mass spectrometry, and elemental analyses. The bronchodilator activity was evaluated using acetylcholine-induced bronchospasm in guinea pigs, and most of the compounds showed significant anti-bronchoconstrictive activity in comparison with standard aminophylline. In addition, the antibacterial activity of all the target compounds was investigated in vitro against Gram-positive and Gram-negative bacteria using ampicillin as a reference drug. Results showed that some of the tested compounds possessed significant antibacterial activity. A pharmacophore model was computed to obtain useful insight into the essential structural features of bronchodilator activity. A structure activity relationship was also discussed.
