One compound (VIId) exhibited activity on both YFV (EC50=1.7 ± 0.8µM) and ZIKV (EC50=4.5 ± 2.1µM). Molecular docking and molecular dynamics simulation studies were conducted to understand the SAR of newly synthesized compounds, to explore the potential target of compound VIId and to investigate the possible binding mode to its target.","PeriodicalId":8314,"journal":{"name":"Archives of Pharmaceutical Sciences Ain Shams University","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87553262","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}

Endostatin (EST) is considered as collagen XVIII fragment formed during extracellular matrix remodeling (ECMR). EST acts as an anti-angiogenic factor. Angiopoietin-2 (Ang II) is a growth factor that increases in several conditions, such as hyperglycemia. The present study was to scrutinize the association of EST and Ang II serum levels with nephropathy in patients with type 2 diabetes mellitus (T2DM). A total of 30 healthy individuals (control) and 120 T2DM patients classified into 60 patients with microalbuminuria and 60 patients without microalbuminuria), aged 45-65 years were included. Fasting Plasma Glucose (FPG), HbA1C%, lipid profile, urinary albumin/creatinine ratio of 30-300 mg/g (UACR), serum urea and creatinine levels were assessed. Both EST and Ang II were measured using the ELISA technique. Ang II and EST levels were elevated in patients with T2DM groups compared with the healthy control group (P<0.001). EST and Ang II were significantly correlated to UACR (r= 0.753, P<0.001) (r= 0.685, P<0.001) and therefore indicate progress to DN. Circulating EST and Ang II were significantly associated with T2DM and predict progression of DN and therefore can be used as biomarkers for the prediction of DN in such a group of patients.","PeriodicalId":8314,"journal":{"name":"Archives of Pharmaceutical Sciences Ain Shams University","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83924654","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}

Besides, it is a progressive condition that has become one of the most common liver disorder in developed countries and is usually accompanied by increased cardiovascular and land liver disease mortality. NAFLD is a spectrum of liver disorders, progressing from simple steatosis to non-alcoholic steatohepatitis which is characterized by inflammation and hepatocellular injury then fibrosis which finally results in cirrhosis and even hepatocellular cancer. However, the molecular mechanism contributing to NAFLD progression is not fully understood. Its pathogenesis has usually been recognized by the \"double-insult\" hypothesis. the \"first insult\" includes accumulation of TGs in the hepatocyte, followed by a \"second insult\" where inflammatory mediators convince hepatocellular injury, inflammation, and fibrosis. In NAFLD, insulin resistance initiates the hepatic steatosis by different mechanisms. Furthermore, it was shown that NAFLD is associated with an inhibition of fatty acid oxidation in the mitochondria and an increase in the release of very-low-density lipoproteins.

In this study, an antibiogram analysis of one hundred and fifty Staphylococcus sp. isolates collected from various clinical specimens, against erythromycin, azithromycin, spiramycin, and clindamycin was carried out. Out of the 150 collected Staphylococcus sp. isolates, 54 isolates (36%) showed resistance to two or more of the tested macrolides. Inducible macrolide, lincosamides and streptogramin type B resistance phenotype (iMLS) using D-test was identified in 15 of the resistant isolates (27.8%). Molecular detection of major genes coding for macrolide resistance, including erythromycin ribosomal methylase (ermA and ermC), and macrolide-streptogramin resistance gene (msrA) was carried out using PCR. It was found that 51.8, 37.1 and 11.1% of the resistant isolates carried one, two and three types of the resistance genes, respectively. However, ermC was the most frequently occurring gene (81.5%), followed by the msrA gene (42.6%), then the ermA gene (35.2%). In conclusion, the genotypic analysis revealed that the majority of the tested isolates harbored two or more macrolide resistance-coding genes where 36% displayed resistance to at least two of the most common macrolide antibiotics used in the treatment of such important pathogens particularly in patients exhibiting hypersensitivity to penicillins according to several international guidelines. Therefore, it is crucial to carry out more epidemiologic studies to clearly understand the problem of increasing macrolide resistance among Staphylococci and to implement new guidelines for the treatment of such important pathogens, particularly in Egypt.","PeriodicalId":8314,"journal":{"name":"Archives of Pharmaceutical Sciences Ain Shams University","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90587319","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}

Methodologically, there isn't a complete picture of the incidence and prevalence of MEs. The broad range of ME rates in literature reflects heterogeneity in the study designs and detection methods used. The current study aimed to detect MEs in reports received from Primary Care Units. A retrospective analysis was applied on such reports dated from March to November 2013 and some fatal cases are taken from 2014. All voluntary reports were included, excluded were errors not associated with drug use and pharmaceutical company reports. Eligible reports underwent assessment using predetermined criteria to pick up MEs. The criteria were applicable on 115 reports, in which MEs were detected. 60% (69/ 115) of ME cases were error cluster while 40% (46/115) were unknown due to either underreporting, lack of data or poor observation and correlation (p< 0.05). Only 7% (8/115) p<0.001 of the reports were pregnancy cases. Moreover, errors associated with vaccine use accounted for 7% (8/115) of the cases while 93% accounted for errors from other drug use at p<0.001. Long-term follow-up was needed but not done by the assessors in 41% (47 of 115) of ME cases at p-value=0.05. Attachments were provided with the reports in 9% (10 /115) of the cases while the majority 91% (105/115) were not (p<0.001).

However, the use of this tool concerning the knowledge and preferences of HCPs has never been evaluated in Egypt. This study aimed to evaluate the HCPs' knowledge, preferences, and barriers to the use of DHPC in Egypt. A cross-sectional study of a random sample of 254 HCPs surveyed via face-to-face interviews to assess the Egyptian HCPs' awareness of DHPC, the preferences, and barriers that affect its use. Among the 297 approached HCPs, only 254 accepted to participate with a response rate of 85.5%, including (50% internists, 22.83% cardiologists, 11.02% neurologists, 11.02% pediatricians, and 5.12% from other specialties). Most HCPs were not familiar with DHPC (N= 254, 61.8%). One-third of the visited HCPs who were aware of concerned drugs' risk(s) got their information from DHPC (N= 149, 36.9%). HCPs preference for communication channel was highest for meetings (N= 254, 65.7%) and least for newsletters (N= 254, 28%).
