Correlates of oral health-related quality of life in a sample of patients with rheumatoid arthritis.

Background: Rheumatoid arthritis (RA) is a prevalent chronic inflammatory joint disease that might exert significant effects on oral health-related quality of life (OHRQoL). This study aimed to investigate OHRQoL in patients with RA.

Methods: This descriptive-analytical study involved 228 RA patients visiting the Jundishapur Dentistry School, Ahvaz, and dental clinics in Ahvaz, south west of Iran, in 2023.

Optimization of carbon emission in an integrated machine-piece scheduling and vehicle routing problem and its solution using MOPSO and NSGAII metaheuristic algorithms.

The growth of the global economy is accompanied by significant energy consumption, and greenhouse gas emissions create various problems such as global warming and environmental degradation. To protect the environment, governments are seeking to reduce carbon emissions. Production systems that operate solely based on economic factors in the workshop only consider problems such as production speed, cost, and processing time.

Design of a sustainable supply chain network of biomass renewable energy in the case of disruption.

Non-renewable energy sources, including fossil fuels, are a type of energy whose consumption rate far exceeds its natural production rate. Therefore, non-renewable resources will be exhausted if alternative energy is not fully developed, leading to an energy crisis in the near future. In this paper, a mathematical model has been proposed for the design of the biomass supply chain of field residues that includes several fields where residue is transferred to hubs after collecting the residue in the hub, the residue is transferred to reactors.

Zebrafish as a model to investigate a biallelic gain-of-function variant in MSGN1, associated with a novel skeletal dysplasia syndrome.

Background/objectives: Rare genetic disorders causing specific congenital developmental abnormalities often manifest in single families. Investigation of disease-causing molecular features are most times lacking, although these investigations may open novel therapeutic options for patients. In this study, we aimed to identify the genetic cause in an Iranian patient with severe skeletal dysplasia and to model its molecular function in zebrafish embryos.

Calculation of IFT in porous media in the presence of different gas and normal alkanes using the modified EoS.

Gas injection can increase oil recovery because the gas-oil interfacial tension is less than the water-oil interfacial tension (IFT) and tends to zero in the miscibility state. However, little information has been provided on the gas-oil movement and penetration mechanisms in the fracture system at the porosity scale. The IFT of oil and gas in the porous medium changes and can control oil recovery.

Novel Loss-of-Function Variants in are Associated with Recessive Sensorineural Hearing Loss in Iranian and Pakistani Patients.

encodes the Cell Division Cycle 14A protein and has been associated with autosomal recessive non-syndromic hearing loss (DFNB32), as well as hearing impairment and infertile male syndrome (HIIMS) since 2016. To date, only nine variants have been associated in patients whose initial symptoms included moderate-to-profound hearing impairment. Exome analysis of Iranian and Pakistani probands who both showed bilateral, sensorineural hearing loss revealed a novel splice site variant (c.

Developing a new approach for (biological) optimal control problems: Application to optimization of laccase production with a comparison between response surface methodology and novel geometric procedure.

Laccase production by indigenous fungus, Phanerochaete chrysosporium, requires solving optimal problems to determine the maximum production of the enzyme within a definite time period and conditions specified in the solid-state fermentation process. For this purpose, parallel to response surface methodology, an analytical approach has been proposed based on the advanced concepts of Poisson geometry and Lie groups, which lead to a system of the Hamiltonian equations. Despite the dating of the Hamiltonian approach to solving biological problems, the novelty of this paper is based on the expression of a Hamiltonian system in notions of Poisson geometry, Lie algebras and symmetry groups and first integrals.

A randomized blinded comparative study of clinical response to surface anatomy guided injection versus sonography guided injection of hyaloronic acid in patients with primary knee osteoarthritis.

Background And Aim: Comparison between the effect of sonographic guided and blind knee injection of hyaluronic acid has been evaluated in this study.

Methods And Materials: Sixty-one patients with primary knee osteoarthritis were randomly allocated into two groups and received intrabursal injection of hyaloronic acid over 3 weeks. The difference between baseline amounts of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Knee Injury and Osteoarthritis Outcome Score and visual analogue scale (VAS) score and these amounts after 6 and 12 weeks were calculated and subsequently compared between the two groups.
