Research ArticleOpen accessEvery word in the titleCOX’S PROPORTIONAL HAZARD MODEL AND CONSTRUCTION OF LIFE TABLE FOR UNDER-FIVESalam Shantikumar SinghA primary data of 836 eligible women in the age group of 15-49 years is used to determine the causal effects of covariates on under-five mortality. The eight covariates viz., Number of family Members (NHM), Type of Toilet Facility (TTF), Total Children ever Born (TCB), Parity (PAR), Duration of Breastfeeding (DBF), use Contraceptive (CMT), DPT and Ideal Number of Girl … …Current Research in Biostatistics, Vol. 4, Issue 1 · 18 Jul 2014 · 8,266 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of Interregional Commodity FlowsWirach Hirun, Sompong SirisoponsilpProblem statement: Commodity Flow Survey (CFS) was launched to collect comprehensive freight flow data throughout the kingdom of Thailand. The survey’s database is the most complete collection of commodity flow data in Thailand. The need to reveal interregional freight characteristics using available data from the CFS led to the objectives of this research. Approach: An origin destination matrix based on … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 22 Nov 2010 · 8,922 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSurvival and Mediation Analysis with Correlated FrailtyUsha S Govindarajulu, Mohsin QadriMany studies have focused on mediation effects, but fewer have focused on these in a time-to-event analysis and even fewer have focused on these effects in a survival model with frailty effects. The purpose of this study was to show unique modeling of correlated frailty effects with mediation and to demonstrate their use through simulations as well as on a … …Current Research in Biostatistics, Vol. 9, Issue 1 · 1 Dec 2019 · 13,005 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrating Stochastic Properties into Traffic Flow Modeling: A Stimulus-Response ApproachKonate N’Golo, Mark Kimathi, Emile DanhoHighway traffic congestion, characterized by its inherent instability, has been extensively studied using deterministic models, providing valuable insights. However, these models often overlook the stochastic nature of driver behavior, a key factor that significantly impacts traffic flow. Recognizing this, a car-following model with discretionary lane changes to analyze their effect on traffic dynamics was introduced. While the mathematical results were … …Journal of Mathematics and Statistics, Vol. 20, Issue 1 · 19 Dec 2024 · 7,153 accessesView PDFCite
Research ArticleOpen accessIn the abstractJoint Modelling of Longitudinal-Time-To-Event with Categorical Variable Indicators of Latent Classes: Application to Tuberculosis DataAdeboye Azeez, Mutambayi Ruffin, Ndege James, Qin YongsongIn many clinical and reliability research reports, the outcomes of basic interest is the time to a particular event happens in order to indicate the person’s “true” state of health or survival status. Different models have been used to analyze such data separately, but may be unsuitable if the longitudinal and health status measures are correlated. In this study, mixed … …Journal of Mathematics and Statistics, Vol. 16, Issue 1 · 9 Jun 2020 · 6,686 accessesView PDFCite
Research ArticleOpen accessIn the abstractClinical Significance of Precise Hyperthermic Intraperitoneal Chemotherapy Up-regulation RP11-356I2.2 Restraining the Occurrence and Development of Gastric CancerYu Yan, Feng Yanlin, Feng Jinxin et al.In order to study the therapeutic effect and possible mechanism of Precise Hyperthermic Intraperitoneal Chemotherapy (HIPEC) on gastric cancer, the expression of RP11-356I2.2 in gastric cancer cell lines and tissues was detected by real-time fluorescence quantitative PCR (RT-PCR). Chi-square test was used to analyze the correlation between the expression and clinic pathological parameters. Western blotting was used to detect the … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 2 · 4 Jun 2020 · 6,487 accessesView PDFCite
Research ArticleOpen accessIn the abstractModelling the Efficacy of Antiretroviral Treatment in HIV Patients: Case of Dr George Mukhari Academic Hospital in Tshwane, Gauteng Province, South AfricaMadimetja Marcus Motshwane, Solly Matshonisa SeeletseThis paper used survival analysis to evaluate the efficacy of antiretroviral (ARV) treatment in HIV patients and also to determine if ARVs reduces the risk of HIV/AIDS. Secondary data were collected from files archived in Tshepang Clinic in Dr George Mukhari Academic Hospital in Tshwane, Gauteng Province of South Africa. Survival time was regressed on influential variables that affect survival. … …American Journal of Applied Sciences, Vol. 13, Issue 8 · 17 Aug 2016 · 7,768 accessesView PDFCite
Research ArticleOpen accessIn the abstractSitagliptin Impairs Healing of Experimentally Induced Gastric Ulcers Via inhibition of iNOS and COX-2 ExpressionAmina Unis, Eman AbdelzaherGastric ulcer healing is a complex process that is regulated by several promoting factors including COX-2 and iNOS. Diabetes mellitus is usually associated with delayed gastric ulcer healing. Hence, the current study was designed to investigate the effect of sitagliptin (dipeptidyl peptidase-4 inhibitor) on gastric ulcer healing and expression of iNOS and COX-2 in rat stomach.The study was conducted on … …American Journal of Pharmacology and Toxicology, Vol. 8, Issue 3 · 4 Sep 2013 · 7,436 accessesView PDFCite

Ahmed, Hoda F. Booles, Wagdy K.B. Khalil et al.The present article aimed to investigate the potential role of the ethanolic extracts of the aerial parts of Jasonia candicans and Jasonia montana in management of Alzheimer’s Disease (AD) in experimental model. Supplementation of drinking water AlCl3 (0.3%) for 16 weeks induced AD in male rats with siginifcant increase in brain Acetylcholinesterase (AchE) activity, Tumour Necrosis Factor (TNF-α), Transforming Growth … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 20 Jun 2013 · 7,830 accessesView PDFCite
