This study was conducted from October 2019 to October 2020.To determine the prevalence of Entamoeba histolytica and Giardia lamblia among patients attending some hospitals (22 May Hospital, Cuban Hospital, Al-Naqeeb Hospital, Al Salam Hospital) in Al-manssora Directorate, Aden - Yemen. This study included 603 patients. Stool samples were obtained from all participants and laboratory conducted using a direct mount preparation with physiological normal saline (0.9%) and iodine stain. The results of the current study showed that the overall prevalence rate was 384/603 (63.68%). The prevalence of E. histolytica and G. lamblia was higher among males (33.34%) than that in female (30.34%). The prevalence rate of these parasites was higher in the age group between 20-67 years old (36.31%), followed by the age group (10-19) years. The study concluded that the prevalence of Entamoeba histolytica and Giardia lamblia among diarrheal patients in Al-manssora Directorate, Aden – Yemen was high

Stability is the main quality characteristic of any drug product, it involves changes in physical, chemical and biopharmaceutical properties. The current work studied the stability of gentamicin (Gen) sulfate injection using HPLC, four samples of Gen were selected. Inj-I, Inj-II, Inj-III, and Inj-IV. The selected injections were stored at room temperature and analyzed at zero time then after three and six months. The analysis was achieved using reverse-phase chromatography with isocratic elution at a flow rate of 1.1 ml/min. Chromatography analysis was performed on the ODS (C8) column, 15× 0.45 cm, 5µm particle size, the column temperature was 30 ºC, and a manual injector with a 20 µl loop was used for the injection of the sample solution and mobile phase. The mobile phase was a mixture of methanol/water / glacial acetic acid/sodium 1-heptane sulfonate. The eluent was monitored with a UV-Detector at a wavelength of 330 nm with a flow rate of 1.1 ml/min. The results of the analysis showed that the pH values of all samples decreased slightly however, it was still within the acceptance range of USP. The influence of storage temperature on the degradation of the drug was evidenced whereas the Inj-I sample was the least degraded, while Inj-IV was the highest degraded sample. The accuracy was evaluated by the percent of recovery at three different concentrations in the range (99.38-100%), the precision of the method was satisfactory, and the values of relative standard deviation were less than 2%.

The study aims to generate vegetation mapping for the study area's existing vegetation and apply a vegetation typification approach that can be used to identify the vegetation structure of any region in the Arabian Peninsula. To highlight the plant diversity and the vegetation communities for nature conservation purposes, a case study in Albaha region, Saudi Arabia is presented, in which the natural vegetation communities and vegetation types of one of the Important Plant Species Areas (IPSA) of Saudi Arabia is evaluated. In an area of 167.6 km2, 97 samples, each with 20X20 m were laid out covering the whole ecological zones of the study area. Data on flora, vegetation cover and topography were gathered from each sample site using Braun-Blanquet method. ITC approach of vegetation typification according to three dimensions (trees, shrubs, and herbs) is applied to identify the structures of each vegetation type. The results showed 319 plant species belonging to 228 genera and 75 families. These species were analyzed and classified into three plant communities and 14 different vegetation types using multivariate analysis program (MVSP) software. Using the percentage of trees, shrubs and herbs, the three-dimensional graphics of vegetation structure presented in this study can be used to determine the vegetation structure of any region in the Arabian Peninsula.

Generic drugs are less expensive than innovator drugs, and their proliferation has become a problem in low-income countries. They need to be therapeutically and pharmaceutically equivalent to the innovator. Levocetirizine dihydrochloride is an effective drug for relieving the signs of chronic urticaria, perennial allergic rhinitis, and seasonal allergic rhinitis. Our investigation into this drug in private pharmacies in Aden, Yemen, revealed that it is sold under the names of 28 brands from different countries of origin. Because of this, it is difficult for medical professionals and patients who use this medication without a prescription to select a suitable, safe, and cost-effective drug product. We assessed the quality and equivalency of six different brands of levocetirizine dihydrochloride film-coated tablets and assigned codes A, B, C, D, E, and F, with Brand A serving as the reference. The UV analytical method was evaluated for quantifying the drug from the tablets. The results indicated that it was accurate and precise. The tablets were evaluated for weight variation, thickness, hardness, friability, drug content, disintegration time, and dissolution. In order to compare the drug's dissolving profiles, the difference factor (f1) and similarity factor (f2) were used. For all six brands, the physicochemical parameter results met the acceptable limits. All six brands showed evidence of dissolving within 15 minutes, with values ranging from 80.05 ±0.81 to 103.83 ±0.90 which were within the recommended value of 80% within 30 minutes for oral solid dosage forms intended for immediate release. According to the f1 and f2 results, only brands B, D, and E were comparable to brand A and could be used interchangeably. In conclusion, four of the six brands are interchangeable. For high-quality public health, a thorough analysis and ongoing monitoring are needed to ascertain the quality and equivalency of the medications marketed under various brands.

Removal of excess fluoride [F-] from the water has been attempted by several authors by using different materials both natural and artificial. The main aim of this study was to the fluoride removal by using the local limestone adopting column method. The use of limestone obtained from the National Company of Cement (NCC) at Wadi Saim deposit and Wadi Nakhleen deposit, in Lahj Governorate, Yemen. X-ray spectroscopy analyses revealed that that limestone are classified as high and very high pure limestone, respectively. Local limestone has fluoride removal abilities by phosphoric acid (PA)- local crushed Limestone treatment (PACLT), with the treated water conforming to WHO guidelines for Fluoride in drinking water. Fluoride removal and pH of treated water attained stability within 3ℎ for defluoridation from 10 mg/L [F-], to 0.20 mg/L with 0.68 mM [PA]. The results may be useful for suitability of local limestone for fluoride removal from drinking water.
一些作者尝试用不同的天然和人工材料去除水中过量的氟化物[F-]。本研究的主要目的是利用当地石灰石采用柱法进行除氟。使用从也门拉赫省Wadi Saim矿床和Wadi Nakhleen矿床的国家水泥公司(NCC)获得的石灰岩。x射线光谱分析表明，该石灰石分为高纯石灰石和极高纯石灰石。当地石灰石具有通过磷酸(PA)-当地石灰石碎处理(PACLT)去除氟的能力，处理后的水符合世卫组织关于饮用水中氟化物的准则。除氟和处理水的pH值在3°范围内稳定，从10 mg/L [F-]降至0.20 mg/L, 0.68 mM [PA]。研究结果可能有助于确定当地石灰石是否适合从饮用水中去除氟化物。

X-ray spectroscopy analyses revealed that that limestone are classified as high and very high pure limestone, respectively. Local limestone has fluoride removal abilities by phosphoric acid (PA)- local crushed Limestone treatment (PACLT), with the treated water conforming to WHO guidelines for Fluoride in drinking water. Fluoride removal and pH of treated water attained stability within 3ℎ for defluoridation from 10 mg/L [F-], to 0.20 mg/L with 0.68 mM [PA]. The results may be useful for suitability of local limestone for fluoride removal from drinking water.","PeriodicalId":11552,"journal":{"name":"Electronic Journal of University of Aden for Basic and Applied Sciences","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82082780","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}
