    peer reviewedThe aim of this study was to determine the levels of mineral compounds in Cistus ladanifer and Cistus libanotis growing in Eastern Morocco from two different regions Jerada (arid climate) and Tafoughalt (humid climate). A total of fifteen elements (Cd, Co, Cr, Cu, Hg, Na, Ni, P, Pb, Zn, Al, Ca, Fe, K and Mg) has been measured by inductive coupled plasma atomic emission spectrometry. Their concentrations have been found to vary in leaves and their essential oils. From the results of the study, P, Al, Ca, Fe, K and Mg are highest in all the samples analysed. Cr and Pb were not detected in essential oil of Cistus libanotis from Jerada and Tafoughalt, respectively. These plants were found to contain appreciable amounts of the elements K, Ca, Fe, Mg, P, Al, Ni, Li, Zn and Cu Witch are important in many biological mechanisms. This study also provides a comprehensive survey of the concentration of elements in plants due to their wide utilisation as herbal fusion or decoction in Eastern Morocco

    Improved Methods for Fluorescence Microscopy Detection of Macromolecules at the Axon Initial Segment

    The axonal initial segment (AIS) is the subcellular compartment required for initiation of the action potential in neurons. Scaffolding and regulatory proteins at the AIS cluster with ion channels ensuring the integrity of electrical signaling. Interference with the configuration of this protein network can lead to profound effects on neuronal polarity, excitability, cell-to-cell connectivity and brain circuit plasticity. As such, the ability to visualize AIS components with precision provides an invaluable opportunity for parsing out key molecular determinants of neuronal function. Fluorescence-based immunolabeling is a sensitive method for morphological and molecular characterization of fine structures in neurons. Yet, even when combined with confocal microscopy, detection of AIS elements with immunofluorescence has been limited by the loss of antigenicity caused by fixative materials. This technical barrier has posed significant limitations in detecting AIS components alone or in combination with other markers. Here, we designed improved protocols targeted to confocal immunofluorescence detection of the AIS marker fibroblast growth factor 14 (FGF14) in combination with the cytoskeletal-associated protein Ankyrin-G, the scaffolding protein βIV-spectrin, voltage-gated Na+ (Nav) channels (especially the Nav1.6 isoform) and critical cell type-specific neuronal markers such as parvalbumin, calbindin, and NeuN in the mouse brain. Notably, we demonstrate that intracardiac perfusion of animals with a commercially available solution containing 1% formaldehyde and 0.5% methanol, followed by brief fixation with cold acetone is an optimal and sensitive protocol for FGF14 and other AIS marker detection that guarantees excellent tissue integrity. With variations in the procedure, we also significantly improved the detection of Nav1.6, a Nav isoform known for its fixative-sensitivity. Overall, this study provides an ensemble of immunohistochemical recipes that permit excellent staining of otherwise invisible molecules within well-preserved tissue architecture. While improving the specific investigation of AIS physiology and cell biology, our thorough study can also serve as a roadmap for optimizing immunodetection of other fixative-sensitive proteins expanding the repertoire of enabling methods for brain studies

    Reproducibility of Statistical Tests Based on Randomised Response Data

    Reproducibility of experimental conclusions is an important topic in various fields, including social studies. The lack of reproducibility in research results not only limits scientific progress, but also wastes time, resources, and undermines society’s confidence in scientific findings. This paper focuses on the statistical reproducibility of hypothesis test outcomes based on data collected using randomised response techniques (RRT). Nonparametric predictive inference (NPI) is used to quantify reproducibility, which is well-suited to treat reproducibility as a prediction problem. NPI relies on few model assumptions and provides lower and upper bounds for reproducibility probabilities. This paper concludes that less variability in the reported responses of RRT methods leads to higher reproducibility of statistical hypothesis tests based on RRT data with the same degree of privacy

    Purpose: To describe the current role played by pharmacists in delivering  pharmaceutical care (PC) in community pharmacies in Jordan (current activities and practices undertaken in the community and extent of provision of PC standards), pharmacists’ perspectives on PC implementation and barriers to implementing PC practices.Methods: This cross sectional study was conducted in 2014 in Amman, the capital of Jordan and Zarqa, the second biggest city in Jordan. The study involved a  validated questionnaire administered at random by trained pharmacy students to 180 community pharmacists. The questionnaire was designed to collect  demographic data, pharmacy practice features displayed by the pharmacists, dispensing activities undertaken, internationally proposed PC practice standards in community pharmacy settings, inter/intra-professional and public heath activities and barriers that may hinder the implementation of PC practice in Jordan.Results: 163 pharmacists agreed to participate in the study (response rate was 90.5 %). Most dispensing activities (98.1%) in the pharmacies were done under the supervision of pharmacists. All pharmacists were willing to implement PC, and nearly all of them (98.8 %) provided basic information about medication use. Nevertheless, only 31.0 % adapted standard procedures for patient’s data collection, 23.1 % formulated a therapeutic plan to be included within the patient’s permanent record in their pharmacy, 24.2 % documented over-the-counter  recommendations, and 29.7 % allocated time to discuss patient’s care plans.  Identified barriers preventing the provision of PC practice included lack of training on the concept (44.9 %) and lack of acceptability from the physicians (43.4 %).Conclusion: Although participating pharmacists showed willingness to implement PC practice, their actual application to the practice was found to be limited. Lack of adequate pharmaceutical training and acceptability by the physicians are the major barriers towards the provision of PC practice in the country.Keywords: Community pharmacists, Pharmaceutical care, Barriers, Jorda
