Ionophores shield the charge of the target ion, enabling it to cross the membrane to be released on the other side. This may consume time and some huge structures need a bulky ionophore. However, water channels enable the passage of many ions at a high rate without the need for carriers that may limit the ion transfer rate. Simulation of living cell membrane in engulfing large molecules through channels is a very interesting mechanism to enhance permselectivity of fabricated polyvinyl chloride (PVC) membrane sensors. Green synthesis of carbonaceous nanoparticles to play this role was fulfilled in nanocarbon dots (CD). The polymerization of β-cyclodextrin with acrylates, either imprinted with the target molecule (in molecularly imprinted polymer, MIP) or not (in non-imprinted polymer, NIP) provided a good enhancement of binding selectivity, in comparison with β-cyclodextrin alone as ionophore. Application of both inventions in the fabrication of three sensors (1; CD/βCD, 2; CD/NIP, and 3; CD/MIP) enabled trace analysis of azoxystrobin fungicide in ranges (10 -11 -10 -5 , 10 -13 -10 -4 and 10 -13 -10 -4 M), respectively, with high selectivity.","PeriodicalId":8314,"journal":{"name":"Archives of Pharmaceutical Sciences Ain Shams University","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84349789","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}

It was a randomized controlled study in which 60 eligible patients were recruited and randomly assigned to either an intervention (N = 30) or a control group (N = 30). The intervention group received pharmaceutical care services including management of drug-related problems (DRPs) in addition to standard care. Patients in the control group received only standard care. Both groups were evaluated for DRPs, disease activity, functional disability, adherence, quality of life, and laboratory tests that include erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) at baseline and after 6 months. After 6 months, a significant difference in DRPs, Morisky medication adherence scale (MMAS-8), number of adverse drug reactions, and administration errors were noted between the intervention and control groups. A significant reduction was observed in disease activity score 28 (DAS28), health assessment questionnaire (HAQ), RA quality of life (RAQoL) score, ESR, and CRP in the intervention group when compared to the control group. In conclusion, the introduction of pharmaceutical care services in RA patient treatment protocol effectively resulted in an improvement in the detection and prevention of drug-related problems. Moreover, these professional pharmaceutical practices showed a significant reduction in DAS28, HAQ, and RAQoL scores indicating a decrease in disease activity, and functional disability with an improvement in patient adherence and quality of life.","PeriodicalId":8314,"journal":{"name":"Archives of Pharmaceutical Sciences Ain Shams University","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81191333","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}

Evaluation of chronic obstructive pulmonary disease (COPD) patients‟ satisfaction with pharmaceutical care services in the chest department outpatient clinic, Ain Shams University Hospitals, Cairo, Egypt, a cross-sectional study utilizing a structurally designed questionnaire was conducted to measure COPD patient satisfaction with pharmaceutical care services. The questionnaire was filled out by thirty COPD patients, after 12 weeks of providing pharmaceutical care services by the researcher (clinical pharmacist). It was a self-administered survey constituted of two main parts; the first one included the patients' demographic data, and the second part included several domains about various pharmaceutical care services. The questionnaire provided a 5-point Likert response scale system used in Arabic and English language. Most of the patients‟ responses were in the “Good” and the “Very good” categories, and the greater age median of the respondents was associated with a better rating of the services. Providing information about the side effects of the medications and the inhaler technique appeared to enhance patients‟ satisfaction. The satisfaction of COPD patients towards the services provided by the clinical pharmacist in the chest outpatient clinic is only intermediate, the older aged patients seemed to be more satisfied with the services provided than their younger counterparts. Efforts should be performed to increase the patient's satisfaction with the clinical pharmacy services.","PeriodicalId":8314,"journal":{"name":"Archives of Pharmaceutical Sciences Ain Shams University","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76186594","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 80 male Wistar rats distributed into 8 groups (n = 10) according to the experiment. We used various antioxidant treatments at their recommended antioxidant doses. All nanoparticles were given orally and daily for 75 days at doses of 100 mg/kg. The oral administration of different nanoparticles (NPs) alone led to dramatic histopathological features, a significant increase in the levels of the TBARS, tumor suppressor p53, and inflammatory markers (TNF-α and IL-6) in the renal tissue. In addition, serum kidney function parameters elevated significantly in NPs treated groups compared with the control group. On the other hand, the renal TAC, GSH, SOD, and TBARS lowered significantly in the renal tissue of rats administered with different NPs compared to the control group. The FOD-NPs-treated groups recorded significantly reduced nephrotoxicity effects as compared to the groups treated with NPs alone.

This was performed against Staphylococcus aureus as a representative of Gram-positive bacteria and Escherichia coli representing Gram-negative bacteria. The satisfactory activity shown against Staphylococcus aureus was a great promoter to test the compounds versus linezolid-resistant MRSA. Promising antimicrobial activity against MRSA was observed for three compounds 3b , 3c, and 3e where compound 3e is the most active showing MIC of 3.05 mg/ml.

Variation in eggshell color/breed of hens has been reported to affect the quality and composition of eggs and eggshells. So, the current study aimed to compare glucosamine sulfate content in ESM separated from white and brown eggs using the HPLC technique and UV detection at 195 nm. The peak area quantification method was used to determine the concentration of glucosamine in both samples. Results revealed that ESM separated from white eggs has a higher content of glucosamine sulfate (11.83% w/w) than ESM separated from brown eggs (10.68% w/w). We conclude that the use of ESM from white eggs may be more valuable than ESM from brown eggs in further biological studies to determine the effect of ESM in the prevention and management of osteoarthritis.","PeriodicalId":8314,"journal":{"name":"Archives of Pharmaceutical Sciences Ain Shams University","volume":"135 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84132880","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}
