Drugs that enter the country by legal means undergo some tests by Supreme Board for Drugs and Medical Appliances (SBDMA) to evaluate the quality of the product. However, some medicines enter the country illegally (smuggling) and this makes them bypass the evaluation of their quality by the SBDMA. This work was carried out to determine the physical quality control parameters of authorized and smuggled drug products marketed in Aden pharmacies. The authorized and smuggled brands of cefuroxime (CEF), atorvastatin (ATR), and carvedilol (CAR) tablets available in Aden pharmacies were selected. The tablets were evaluated for their physical properties and quality control parameters including weight variation, hardness, friability, and disintegration test. The level of drug content also was evaluated using UV spectroscopy. The physical assessment showed that the authorized and smuggled brands of the same products were uniform in shape, color, packing, and labeling information except for the registration number and manufacture date which were present only on the authorized brands. The three authorized and smuggled brands of CEF, ATR, and CAR complied with the official specifications for weight version, diameter, thickness and hardness, friability, and disintegration tests except for the hardness value of ATR. All authorized brands agreed with the label claims whereas some smuggled brands contained the appropriate active ingredients but did not contain the right amounts.","PeriodicalId":11552,"journal":{"name":"Electronic Journal of University of Aden for Basic and Applied Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90809116","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}

There were two methods, the First method included chromotrope 2R, chromotrope 2B, arsenazo I, ASPANDS, and chromotrope 2C for the determination of AMB.HCl in its pure and pharmaceutical forms. The first method is based on the drug oxidation with Potassium permanganate in excess. The unreacted potassium permanganate was determined by measuring the absorbance of colored chromotropic acid azo dyes namely chromotrope 2R, chromotrope 2B, arsenazo I, SPADNS, and chromotrope 2C. The suitable ƛmax were 500, 510, 500, 510, and 520 nm, respectively. Under optimized conditions, Beer’s Law showed good correlation and obeyed in the concentration range 1.51-7.46, 0.82-4.97, 1.65-6.63, 0.82-6.63, and 1.73-8.29 µg mL-1 for chromotrope 2R, chromotrope 2B, arsenazo I , SPADNS, and chromotrope 2C. The apparent molar absorptivity, Sandell sensitivity, LOD, and LOQ were calculated. Pure and pharmaceutical forms containing AMB.HCl were analyzed and tested for the validity of the proposed methods. The Second method spectrophotometric titration is based on the determination of unreacted potassium permanganate using spectrophotometric titration against ferrous ammonium sulfate, where the end-point was detected spectrophotometrically using ferrion indicator at 510 nm, the Relative standard deviation where 0.23-2.04 with average recovery 100.35-103%.","PeriodicalId":11552,"journal":{"name":"Electronic Journal of University of Aden for Basic and Applied Sciences","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77711840","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}

The present work explains the compositional dependence of many physical properties of GexBi5S95-x (x = 0, 10, 20, 30, 35 and 45 at. %). Increasing Ge content reduces the fraction of floppy modes, the lone pair electrons, the stoichiometric deviation, and the heat of atomization, while the average coordination number 〈r〉, constraints, density, and molar volume increased, indicating the alloys have moved from floppy to rigid mode. The average overall bond energy, electronegativity difference, band gap energy, and glass transition temperature were estimated by analyzing the bond energies and its distribution based on the bond ordered network model (CONM). It has been found that all these parameters increase with Ge ≤ 30 at. % and decrease with the further increase of Ge content. This behavior can be explained in terms of the network chemical percolation threshold proposed by Tanaka. This threshold represents a topological phase transition from a two-dimensional structure at r˂2.67 to a three-dimensional structure at r≥2.67. The incorporation of Ge into the glassy Bi-S system yields interesting physical properties such as threshold and phase transition, confirming this composition's suitability for optical storage media.","PeriodicalId":11552,"journal":{"name":"Electronic Journal of University of Aden for Basic and Applied Sciences","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83852213","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}

The pH of all the cream samples was determined and metals quantification was carried out using ICP-OES after acid digestion while that of hydroquinone was done using HPLC. The health risk of dermal exposure to heavy metals via the regular application was done by evaluating the carcinogenic and non-carcinogenic risk. The pH of all the samples are acidic and it follows this trend; Sample 3 > Sample 1 > Sample 4 > Sample 2. All the metals considered in this study were detected in all the analyzed samples except Cd, Co and Cr in sample 1, As, Ba and Pb in sample 2, Ag, As and Hg in sample 3 and Ba in sample 4. Highest levels of Al, Co, Pb and Zn were recorded in Sample 3 (Organic cream). Though the concentrations of most of the toxic metals (Al, Zn and Mn) are above the permissible levels, they pose no non-carcinogenic health risk based on the calculated HQ and HI. The carcinogenic risk of metals in the sampled creams were all within the acceptable limit except that of Cd. Hydroquinone was detected in all the four samples analyzed ranging between 2.58 and 4.17 % which exceeded the permissible limit by WHO. This finding show that long-term use of skin-whitening-creams may pose serious health hazards so, public should be continually enlightening on the hazardous health effects of the use.","PeriodicalId":11552,"journal":{"name":"Electronic Journal of University of Aden for Basic and Applied Sciences","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72799536","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}

The overall prevalence of E. gingivalis was 18.3% and the highest prevalence of E. gingivalis was among periodontitis group (29%) followed by gingivitis group (18%), and healthy group (8%). The highest prevalence (23.7%) of E. gingivalis was found among the age group 40-49 years. Infection was highly significant in males than females (23.7% vs.12.5%). With regard to risk factors, the prevalence of E. gingivalis was common in non-tooth brush users, smokers, qat chewers, and diabetic patients and there were significant differences between tooth-brush users and non-tooth brush users, smokers and non-smokers, qat chewers and non-gat chewers, and between diabetic and non-diabetic patients and occurrence of E. gingivalis.
