Research ArticleOpen accessEvery word in the titleThe Effect of a 4th Generation-Cephalosporin Introduction upon the Incidence of Multidrug-Resistant Gram-Negative Bacteria in a Non-Teaching HospitalGuilherme Henrique Campos Furtado, Luciana Baria Perdiz, Eduardo Alexandrino Servolo MedeirosProblem statement: Antimicrobial resistance is a worrisome situation in hospitals around the world and the misuse of certain classes of antimicrobials has contributed for this situation. Approach: We performed a prospective surveillance study on the incidence of multi-drug resistant bacteria before (phase 1) and after (phase 2) the introduction of a 4th-generation cephalosporin in a non-teaching hospital. Results: There was … …American Journal of Infectious Diseases, Vol. 4, Issue 4 · 31 Dec 2008 · 6,876 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHill Climbing Method Using Claus Model for Categorical DataB. OnoghojobiProblem statement: In this study, a locally unbiased test statistic based on the Claussian method was presented. Approach: In this respect, exploiting special structures of modified quadratic hill climbing method and the Claussian statistics were considered. Results: We derived a non-modified quadratic hill-climbing procedure. The performance of the model in testing the estimation of Latent data was shown. Conclusion/Recommendations: The … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,298 accessesView PDFCite
Research ArticleOpen accessIn the abstractAttribute Reduction in Bipolar Intuitionistic Fuzzy Relation SystemWeiyuan Wang, Qian WangBipolar intuitionistic fuzzy relation system (BIFRS) effectively characterize the bipolarity in real-world data by introducing positive and negative membership and non-membership degrees. To address redundancy caused by high-dimensional attributes, this paper proposes an attribute reduction method based on bipolar intuitionistic discernibility matrices. By constructing positive discernibility matrix M+∗ matrix M−∗ and negative discernibility , we systematically identify the minimal attribute … …Journal of Mathematics and Statistics, Vol. 22, Issue 1 · 16 Jul 2026 · 1,063 accessesView PDFCite
Case ReportOpen accessIn the abstractA Case Report of Severe Malaria Due to Plasmodium falciparum Malaria Complicated by Symmetrical Peripheral Gangrene (SPG) at the Matlaboul Fawzaini National Hospital Center, Touba, SenegalJules Yindoni Zande, Ndeye Fatou Ngom et al.Malaria remains a major public health problem worldwide, particularly in Africa. Symmetrical Peripheral Gangrene (SPG) is a distal ischemic lesion affecting at least two extremities in the absence of proximal arterial obstruction and vasculitis. It is a rare and severe clinical entity. Its association with malaria is rare, with approximately 27 cases reported worldwide, mostly in Asia. A 15-year-old male … …American Journal of Infectious Diseases, Vol. 21, Issue 1 · 22 Jan 2026 · 2,806 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntiproliferative Potential of Pomegranate Peel Extract in MDA-MB Breast Cancer Cell LinesManal Asif Hamdulay, Fatema Yusuf Singaporewala, Grisilda Vidya Bernhardt et al.Nutraceuticals have gained recognition as adjuvant therapies in cancer treatment due to their non-toxic and protective properties. Among various natural products, pomegranate peel with high antioxidant capacity and rich polyphenol content suggest potential anticancer properties. Previous studies have shown promising anticancer effects of other parts of the pomegranate. The purpose of this research is to compare the effectiveness of Pomegranate … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 13 May 2025 · 5,582 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploring University Students' Perceptions of AI Tools in Programming Education: An Extended TAM ApproachAreej Abdullah AlfuhaidGenerative Artificial Intelligence (AI) is commonly used in programming education. Tools such as ChatGPT and GitHub Copilot aid in code generation, debugging, and explanation. The benefits are clear, though concerns about learning quality and academic integrity persist.We tested an extended Technology Acceptance Model (TAM) for university programming courses. The model included perceived usefulness and perceived ease of use. It added … …Journal of Computer Science, Vol. 22, Issue 3 · 11 Mar 2026 · 2,061 accessesView PDFCite
Research ArticleOpen accessIn the abstractCadmium Stress Responses in Medicinal and Oilseed Plants: Safflower as a Promising Candidate for Soil Cadmium RemediationChristos Kikis, Giorgos Thalassinos, Vasileios AntoniadisThis study investigated the growth responses of five economically important plants—chamomile (Matricaria recutita), oregano (Origanum vulgare), safflower (Carthamus tinctorius), sage (Salvia officinalis), and wormwood (Artemisia absinthium) exposed to increasing Cd levels. Over 60 days, plants were subjected to Cd concentrations of 0, 1, 2, 3, and 4 mg per pot. Growth parameters and Cd accumulation were then assessed.
