Chitosan beads were prepared by dropping riboflavin-loaded, chitosan (CS) solution into a curing medium composed of either an aqueous solution of TPP, SLS or a combination of these solutes. The resultant beads were characterized in terms of their size, drug encapsulation efficiency, water uptake properties by gravimetry and image analysis. Drug release properties of the prepared beads were studied using USP Apparatus 1 in media with different pH and ionic strength. Composites (CS/TPP, CS/SLS, and CS/TPP/SLS) were also evaluated using DSC, FTIR and contact angle measurements. Encapsulation efficiency was found to be 93%, 93.2% and 93.1% for CS/TPP, CS/SLS, and CS/TPP/SLS beads respectively and did not show any dependence on the composition of the curing medium for riboflavin. FTIR data suggested the presence of electrostatic interactions between positively charged amine group of CS and the negatively charged TPP and SLS. Drug release from the prepared beads was prolonged with CS/SLS beads releasing the drug faster than CS/TPP beads. The slowest drug release was observed in the case of CS/TPP/SLS beads. Drug release from the different types of beads was pH-dependent with the fastest release observed in 0.1 N HCl. Gravimetric water uptake was highest for CS/SLS beads followed by CS/TPP and CS/TPP/SLS respectively. Swelling study using image analysis showed a similar trend to the gravimetric water uptake results. The drug release and water uptake results could be explained by the effect of SLS on the wettability of the beads and the ability of the release medium to hydrate them which was confirmed by the high contact angle between water and CS/TPP/SLS composites.","PeriodicalId":14719,"journal":{"name":"Jordan Journal of Pharmaceutical Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42148838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the effectiveness of traditional anticancer therapies such as 5-Flurouracil (5-FU), poor therapeutic outcomes are reported in many cases, due to tumor recurrence and chemoresistance. Intracellular lipid accumulation as lipid droplets (LDs) is now a well-recognized hallmark of cancer. However, the influence of LDs accumulation in cancer progression and treatment remains to be elucidated. Adjuvant use of non-chemotherapeutic drugs (e.g. NSAIDs and corticosteroids) with anticancer drugs to manage cancer related symptoms, may though serve as factors modulating the therapeutic response to anticancer agents via LDs related mechanisms. The aim of this study is to evaluate possible strategies influencing chemoresistance by attenuating LDs biogenesis and function. LDs levels in eight human cancer cell lines were measured. The existence of correlation between the cellular levels of LDs and cytotoxicity of ten chemotherapeutic agents was evaluated. A moderate correlation between basal LDs levels and the half inhibitory concentration (IC50) values of 5-FU on selected cell lines was established (r2= 0.5235). Nevertheless, LDs levels were significantly elevated following exposure to 5-FU. A549 human lung cancer cells showed the highest increase in LD accumulation (***P >0.001) compared to their basal levels of LDs. LDs levels were also assessed following exposure to 5-FU in the presence of sub-lethal doses of celecoxib (CXB), dexamethasone (DEX), and simvastatin (SMV). Interestingly, CXB and DEX exposure to 5-FUtreated cells resulted in an alleviation in the antiproliferative activities of 5-FU in MDA-MB-468 and HCT116 but not in A549 cells. While, SMV exposure to 5-FU-treated cells resulted in reduced antiproliferative activities of 5-FU in MDA-MB-468 only. These results strongly suggest that increased LDs levels caused by CXB, DEX, and SMV may contribute in the development of a resistance mechanism exist only in some cancer types, which therefore, attenuates responses to 5- FU. The inhibition of phospholipid metabolism by DEX, as well as the inhibition of 3-hydroxy-3- methylglutaryl-CoA reductase (HMGCR) by SMV were expected to result in the up regulation of triacylglycerol (TAG), leading to LDs accumulation. This study highlights the importance of assessing drug-drug interaction before designing integrated therapy regimens for cancer patients receiving 5-FU treatment. Further studies are needed to discover the role of TAG inhibition on the sensitivity of cancer cells against 5-FU.","PeriodicalId":14719,"journal":{"name":"Jordan Journal of Pharmaceutical Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43079794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used an online questionnaire which distributed randomly for data collection. The questionnaire consists of 52 questions to measure the knowledge, attitudes, and awareness of antibiotic use and resistance. Statistical Package for the Social Sciences (SPSS) version 25 was used to analyze the data collected. \u0000Results: A total of 744 participated in the study and completed the questionnaire, and the majority of them (60.5 %; n= 450 out of 744) were from the Hebron Governorate. The major of the respondents also were females (n= 653, 87.8%) and their age between 20-35 years old (n= 498, 66.9%) with a bachelor degree (n= 502, 67.5%). The majority of them (75.5%, n= 560) think that antibiotics should be given only by prescription, and about half of the people (52%= n= 387) believe that antibiotics are not safe. Most participants relied on the physician for dispensing the antibiotic (60.1%, n= 455) but the same percentage of them use leftover antibiotics that have been used previously. Four hundred eighty-three (65%, n= 483) who completed the questionnaire heard about the antibiotic resistance term from medical staff, and their main primary sources of information about antibiotics and medicines were from health staff too (50%, n= 371), then internet (25%, n= 185). Some people (16%, n= 119) mentioned that pharmacists have a role in educating them and providing all the necessary information, or advice about the use of medicines and the dangers of medication misuse. Most of the participants obtained the antibiotics by prescription from a doctor (n= 339, 45.6%), then from the Pharmacist (n= 91, 12.2%), and 63 persons (8.5%) purchases them on their own. Quite a high number of participants (n= 348, 46.8%) stop taking antibiotics when they start feeling better. According to the results obtained, social media was the primary source of information regarding antibiotic resistance. \u0000Conclusions: Higher education, younger age, gender, profession, and a high monthly income were associated significantly with good knowledge and a positive attitude toward antibiotic use. Educational interventions for appropriate antibiotic use are needed all the time and enforcing antibiotics regulations should be also considered to reduce antibiotic resistance.","PeriodicalId":14719,"journal":{"name":"Jordan Journal of Pharmaceutical Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42864167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Early CVD risk assessment and management (RAM) has demonstrated to be effective in decreasing CVD-related burden. However, CVDRAM services face many challenges and barriers in the community. Mobile technology has been advocated to facilitate access to CVDRAM for both healthcare providers and patients to overcome these barriers. Nevertheless, there is limited availability and use of CVDRAM-related mobile technology in the Middle East region. \u0000Objectives: To develop and implement an English and Arabic version of a mobile and a web application for CVDRAM in both, community pharmacies and selected primary care centres in Qatar. \u0000Methodology: This study was conducted in two phases. In Phase 1, translation of the EPI·RxISK™ CV risk calculator (ERC) into the Arabic language was conducted based on guidelines developed by the International Society for Pharmacoeconomics and Outcomes Research. The English/Arabic version of the ERC was pilot tested by potential end users, consisting of a sample of community pharmacists (CRxs) and members of the public (MOP) accessing community pharmacy services. Semi-structured interviews were conducted based on the constructs of the Mobile Application Rating Scale (MARS) and data were analyzed using deductive content analysis. In Phase 2, a prospective observational study (QCARxE) is underway to explore the feasibility of using the ERC in patients accessing primary health care services for CVDRAM, including community pharmacies and primary health care centers (PHCC). \u0000Results: In Phase 1, a total of 10 CRxs and 5 MOP were interviewed. The data derived from the interviews indicate that the ERC web and mobile application were overall, positively perceived as having quality engagement, functionality, aesthetics, information and subjective quality attributes. To date, a total of 36 patients have enrolled in the QCARxE study (20 from PHCC and 16 from community pharmacies). At their initial CVD risk assessment visit, the mean CVD risk score for these patients was 28.3%, and the most prevalent risk factor was obesity (mean BMI = 30.2 kg/m²). \u0000Conclusion: The themes derived from the interviews indicate that the ERC was overall, positively perceived. Preliminary data derived from the QCARxE study indicated a significant proportion of patients accessing primary health care services are at high CVD risk. It is speculated that the use of the ERC will enable patients to become better aware of their CVD risk and improve access to risk factor interventions.","PeriodicalId":14719,"journal":{"name":"Jordan Journal of Pharmaceutical Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45976532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several studies have been proposed to use guava leaves extract in several preparations. However, applying guava leaves extract as a preservative in a pharmaceutical product has not been studied previously. In the present work, Guava leaves extract was used as natural preservative instead of chemical ones (methyl and propyl paraben). Guava leaves were extracted with ethanol 95% as extraction solvent with a percentage yield of 20%. This extract was tested by HPLC; several phenolic compounds were detected. To determine the ability to use this extract as a preservative, antimicrobial effectiveness test (preservative efficacy test) was conducted for extracted powder in purified water at different concentrations (0.5, 1.0, 1.5, and 2.0 % w/w), against three bacteria, one gram-positive (S. aureus), two gram-negative (P. aeruginosa, E. coli) and two fungi: one yeast (Candida albicans) and one mold (Aspergillus (Niger) brasiliensis). Results showed that 2% was effective and passed the test of preservative effectiveness test; this concentration was used in semi-solid pharmaceutical products. For this purpose, six different preparations (Ketoconazole shampoo, Clotrimazole Cream, Permethrin Cream, Gentamycin Cream, Ibuprofen gel, Indomethacin emulgel) were used. Chemical preservative was replaced by natural one (guava leaves extract powder) to serve as a preservative. Three out of the six preparations (Ketoconazole shampoo, Clotrimazole Cream, Ibuprofen gel,) passed preservative efficacy test. These preparations were fully checked-up by chemical (drug content,) physical (odor, physical appearance) and biological test (total count test) for three months at accelerated conditions.

However, NMR costs and complexity hinder a use as point-of-care and biochemical sensor instrumentation. Low field NMR (LF-NMR) is an inexpensive and low footprint technique to obtain physical, chemical, electronic and structural information on small molecules, but suffers from poor spectral dispersion, especially when applied to the analysis of mixtures. Subspectral editing employing optimal control pulses is a suitable approach to cope with the severe signal superpositions in complex mixture spectra at low field. \u0000We have calculated the optimal control pulse shapes at 0.5 T NMR frequency using the Krotov algorithm. Downsizing the complexity of the algorithm from exponential to polynomial is shown to be possible by using a system approach with each system corresponding to a (small) molecule. In this way compound selective excitation pulses can be calculated. The signals of substructures of the cyclopentenone molecule were excited using optimal control pulses calculated by the Krotov algorithm demonstrating the feasibility of subspectral editing. Likewise, for a mixture of benzoic acid and alanine, editing of the signals of either benzoic acid or alanine employing optimal control pulses was shown to be possible. \u0000The obtained results are promising and can be extended to the targeted analysis of complex mixtures such as biofluids or metabolic samples at low field strengths opening access for benchtop NMR to point of care settings. Moreover, the LF-NMR was improved to allow a unique detection and reliable quantification of metabolites in biofluids like blood, urine, cerebrospinal fluid, or even tissue. In contrast to standard large scale NMR equipment the portable LF-NMR allows for an analysis of the chemical composition of biofluid samples directly at the patient (point-of-care). \u0000LF-NMR can be freely programmable for detecting and detecting and sensing sets of small molecules which deliver information on the health status of a person.

Also, patients were asked to conduct laboratory urine test to determine the rate of infectious complications within one-month post-procedure. \u0000Results: Three hundred sixty-one patients were recruited for the study. The adherence rate to guidelines regarding indication, choice, and dose of pre-operative antibiotics was 90.3%, 2.8%, and 77.8% respectively. The duration was concordant with guidelines in only 3.4% of participants. A total of 41.8% of patients completed follow-up. Among those, 4.6% developed bacterial UTIs, and 0.7% developed BSI. \u0000Conclusion: Adherence to SAP guidelines in endourological procedures is far from optimal, especially by an inappropriate selection of broad-spectrum antibiotics as the agent of choice and prolonged use of antibiotics after the procedure in the absence of any documented infectious complication.","PeriodicalId":14719,"journal":{"name":"Jordan Journal of Pharmaceutical Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43749597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
