Structural Equation Modeling to Detect Predictors of CD4 Cell Count Change due to Long Term Antiretroviral Therapy Administered to HIV-Positive Adults at Felege Hiwot Teaching and Specialized Hospital, Bahir Dar, Ethiopia

Background The relationship between predictors and the variable of interest was estimated using a structural equation model which is used to predict latent variables. The main advantage of the SEM is the ability to estimate the direct and indirect pathways of the effect of the primary independent va…

Pharmacodynamic Modeling of Sunscreens: New Efficacy Evaluation, Risks of Sunburn and Melanoma and Very Low to Very High Sun Protection Factor

Pharmacodynamic modeling of sunscreens was performed using a new concept of Skin UV Index (SUI) on the exposed skin as a parameter to evaluate the potential effectiveness of sunscreens against sun damage. The SUI predicts the UV heat intensity on the skin surface in terms of the solar UV Index at th…

RETRACTED: Monte Carlo Approach To Genotype By Environment Interaction Models

This article has been retracted on 10 February 2021. VIEW THE RETRACTION NOTICE (https://doi.org/10.14302/issn.2643-2811.jmbr-25-5847) Understanding the implication of Genotype-by-Environment (GXE) interaction structure is an important consideration in plant breeding programs. Traditional statistica…

Mathematical Modeling and Epidemic Prediction of COVID-19 and its Significance to Epidemic Prevention and Control Measures

Background Since receiving unexplained pneumonia patients at the Jinyintan Hospital in Wuhan, China in December 2019, the new coronavirus (COVID-19) has rapidly spread in Wuhan, China and spread to the entire China and some neighboring countries. We establish the dynamics model of infectious disease…

Effect of the Biofield Energy Treated Proprietary Test Formulation for Sleep Biomarkers in the Unpredictable Chronic Stress (UCS) Animal Model 

Sleep biomarkers in brain such as melatonin, BDNF (Brain-derived neurotrophic factor), PGD2 (Prostaglandin D2), leptin, orexin-A, and acetylcholine were evaluated in the unpredictable chronic stress (UCS) rodent model in the presence of Consciousness Energy Healing Treated (the Trivedi Effect®) nove…

Nitrogen Leaching Loss Estimation from Paddy Soil in the Taihu Lake Region of China by a Newly Developed Simple Model

Nitrogen leaching as a direct pathway of N loss from agricultural land can negatively affect groundwater and surface water quality. However, a simple and efficient method for nitrogen leaching loss estimation is still inefficient. In this study, an exponential model was developed using the experimen…

Spectroscopic and Foliar pH Model for Yield Prediction in a Symbiotic Corn Production 

The agronomic management of symbiotic (S) inoculations, by means of bio-fertilizers (BF), is aimed at inducing modifications of the plant rhizosphere and thereafter of the phenotype and yield of the crop. It is here shown that the yield response of maize to a symbiotic treatment may be correlated to…

Evaluation of Anti-Aging Activity of the Biofield Energy Treated Novel Test Formulation Using SIRT1 and Telomerase Activity in in Vitro Model

Telomerase and SIRT1 (member of the sirtuin protein family) along with the lifestyle and diet are the major determinants of aging and its associated diseases such as cancer and cardiovascular disorders. The study objective was to investigate the effect of Consciousness Energy Healing based novel tes…

Genetic-Mathematical Modelling of Mutational Processes in a Population

Processes of genetic-mathematical modeling of a population development are considered. A basic distinction in the mathematical description of a family tree and a population is shown. In a family tree alternation of generations has discrete character. In a population there is a continuous alternation…

Enhanced Healing and Bone re-Modelling by Low-Level Laser Therapy for Rapid Pain Control in Pediatric Fractures

Objective The current clinical case series assess the clinical outcome of the use of low-level laser in the treatment of painful pediatric fractures not solidly consolidated and re-modelled after casting for a standard of 4-6 weeks Materials and Methods The patient cohort consisted of 17 consecutive…

Chest Wall Prostheses for Pectus Excavatum and Poland Syndrome Using 3D-Printed Models: Technique and Outcomes After 25 Years' Experience

Background: Chest wall deformities may be managed with skeletal manipulation, which risks life-threatening complications. Custom-made prostheses are a less invasive surgical option, manufactured from silicone elastomer using 3D computed tomographic reconstruction and 3D-printed thoracic models. Meth…

Retinal and Cortical Contributions to Excessive V1 Neuron Firing Rate Variability in Schizophrenia: A Computational Modeling Analysis

Excessive variability in behavioral performance and neuronal activation is a common finding in studies of schizophrenia. Recent evidence suggests that this may be due to an imbalance in the ratio of excitation to inhibition in brain function, or E/I imbalance. We used computational modeling of visua…

Modeling of Talent Acquisition for Organizational Development

In this work, we try to explain the concept of human talent with the help of some equations and models, which are not generated by any one previously. Here we also trying to explain ‘human talent is not resources it’s itself one of the great sources to find out all possible resources’. Because we ca…

Modeling of Dynamic/Situational Leadership for Effective Entrepreneurship Development

In this article we try to pay attention of readers, researchers and management executives how one can adapting situational leadership in another words dynamic leadership and enhance organization performance for goal attainment with high motivational leverages for effective team building and teamwork…

Insight into Management Issues modeling for Perfect Business Simulation

In this paper, I try to focus on widely growing field of Management Science; and that, “Modeling of Management Issues “. Now days Business Simulation techniques are used to earn more profit from Business and this is only issues control future course of actions properly. By using models we can predic…

A Multilevel Hazards Model for Child Mortality In Nigeria

Many researchers have devoted considerable attention to the impact of individual-level factors on child mortality, but little is known about how family and community characteristics affect health of children. Trend in child mortality as well as its determinants, has long been the subject of academic…

Flame Propagation Model and Combustion Phenomena: Observations, Characteristics, Investigations, Technical Indicators, and Mechanisms

Critical conditions are usually obtained for ignition in a self-heating solid system consisting of two components generating heat independently, one component being inexhaustible and the other exhaustible by either simple first order or autocatalytic reaction. Ignition depends upon whether the exhau…

Reproductive Performance and Factors Influencing Fetal Outcome: A Practical Guide to Experiments on Lung Development in A Nitro Fen-Induced Rat Model for Congenital Diaphragmatic Hernia

Our study aims to help researchers calculate resources based on a rat breeding colony for experiments on fetal lung development. The Wistar rat is commonly used in experimental research. In the context of fetal lung studies, the nitrofen rat is a model for pulmonary hypoplasia and congenital diaphra…

Modelling Development in Plant Anatomy

Four rules for good anatomical modeling of plants are explored. First, the cell is the reference source for modelling at any level. Second, developmental signaling occurs between few cells, about 12. Third, rules of are algorithmic and not simply physical forces as proposed by Thompson. Finally, it…
