An efficient discrete Chebyshev polynomials strategy for tempered time fractional nonlinear Schrödinger problems.

Introduction: An interesting type of fractional derivatives that has received widespread attention in recent years is the tempered fractional derivatives. These fractional derivatives are a generalization of the well-known fractional derivatives, such as Caputo and Riemann-Liouville. In fact, these derivatives are obtained by multiplying the expressed fractional derivatives by an exponential factor.

Contribution of obesity to racial and ethnic disparities in the risk of fetal myelomeningocele: a population-based study.

Background: Prepregnancy obesity and racial-ethnic disparities has been shown to be associated with meningomyelocele.

Objective: This study aimed to investigate the association of maternal periconceptional factors, including race-ethnicity and prepregnancy body mass index, with the prevalence of isolated fetal myelomeningocele.

Methods: This was a population-based cross-sectional study using Centers for Disease Control and Prevention birth data from 2016 to 2021.

Orthonormal piecewise Vieta-Lucas functions for the numerical solution of the one- and two-dimensional piecewise fractional Galilei invariant advection-diffusion equations.

Introduction: Recently, a new family of fractional derivatives called the piecewise fractional derivatives has been introduced, arguing that for some problems, each of the classical fractional derivatives may not be able to provide an accurate statement of the consideration problem alone. In defining this kind of derivatives, several types of fractional derivatives can be used simultaneously.

Objectives: This study introduces a new kind of piecewise fractional derivative by employing the Caputo type distributed-order fractional derivative and ABC fractional derivative.

Association of IL-22 and IL-22RA1 gene variants in Iranian patients with colorectal cancer.

Aim: In the current study, it was hypothesized that single nucleotide polymorphisms (SNPs) in the regulatory region of the IL-22 signaling pathway genes, including IL-22 and IL-22RA1 variants, may be associated with CRC susceptibility.

Background: The important role of pro-inflammatory cytokines during tumorigenesis is well-established. In recent years, IL-22 has been linked with colorectal cancer (CRC) through a number of mechanistic and observational studies.

Modeling and forecasting the spread and death rate of coronavirus (COVID-19) in the world using time series models.

Coronaviruses are a huge family of viruses that affect neurological, gastrointestinal, hepatic and respiratory systems. The numbers of confirmed cases are increased daily in different countries, especially in Unites State America, Spain, Italy, Germany, China, Iran, South Korea and others. The spread of the COVID-19 has many dangers and needs strict special plans and policies.

Gallbladder cancer integrated bioinformatics analysis of protein profile data.

Aim: Identifying the critical genes that differentiate gall bladder cancer from a normal gall bladder and the related biological terms was the aim of this study.

Background: The molecular mechanism underlying gall bladder cancer (GBC) trigger and development still requires investigations. Potential therapeutic biomarkers can be identified through protein-protein interaction network prediction of proteome as a complementary study.

Partial Fractionation of Venoms from Two Iranian Vipers, Echis carinatus and Cerastes persicus Fieldi and Evaluation of Their Antiplatelet Activity.

Platelet aggregation inhibitory effect and anticoagulant properties of fractions separated from the venoms of Cerastes persicus fieldi and Echis carinatus were investigated. The partial fractionation was performed on a Sephadex G-100 column. Two fractions separated from Cerastes persicus fieldi showed anti platelet aggregation activity on ADP (200 μM)-induced platelet aggregation (ca 80% inhibition).
