Background: The human CYP2B subfamily consists of one functional gene (CYP2B6) and one pseudogene (CYP2B7P). Cytochrome P450 2B6 (CYP2B6) is a highly polymorphic enzyme that shows marked interindividual and interethnic variations. Currently, 38 alleles have been described, and some of the allelic variants have been associated with low enzyme activity. The aim of this study was to investigate the frequencies of CYP2B64, CYP2B65, and CYP2B66 alleles in the Mazani ethnic group among Iranian Population.
Methods: The study was conducted in 289 unrelated healthy volunteers. DNA was extracted from peripheral blood and analyzed by the PCR-RFLP protocol. The PCR product was digested with restriction enzymes and then separated using agarose gel electrophoresis.
Results: The frequency of CYP2B64, CYP2B65, and CYP2B66 in this study was 34.60%, 7.26%, and 34.54%, respectively.
Conclusion: The frequency of the CYP2B64 allele in the Mazani ethnic group was much higher (34.60%) than other population. The frequency of CYP2B66 (34.54%) also was higher than its frequency in other previously reported population. But the frequency of CYP2B65 in this study was lower than expected. These results will be useful in understanding the ethnic diversity in Iranian population and offer a preliminary basis for more rational use of drugs that are substrates for CYP2B6 in this population.

Background: One of the significant challenges that can arise during cataract surgery is the occurrence of posterior capsule rupture (PCR) and vitreous loss. It may result in different complications including cystoid macular edema, endophthalmitis, glaucoma, and considerably retinal detachment which consequently contributes to poor functional outcomes.
Methods: This study was a prospective double blinded randomized clinical trial including 42 patients with previous complicated cataract surgery including posterior capsular rupture and consequently vitreous loss that anterior vitrectomy was done for them.

Inherited retinal diseases (IRDs) may have significant diagnostic challenges due to their genetic complexity and diverse inheritance patterns. Advanced genotyping tools like exome sequencing (ES) offer promising opportunities for identifying causative variants and improving disease management. This retrospective study was aimed to present prevalent pathogenic and novel variants in patients diagnosed with IRDs using ES.

Introduction: In Iran, the assessment of osteoporosis through tools like dual-energy X-ray absorptiometry poses significant challenges due to their high costs and limited availability, particularly in small cities and rural areas. Our objective was to employ a variety of machine learning (ML) techniques to evaluate the accuracy and precision of each method, with the aim of identifying the most accurate pattern for diagnosing the osteoporosis risks.
Methods: We analysed the data related to osteoporosis risk factors obtained from the Fasa Adults Cohort Study in eight ML methods, including logistic regression (LR), baseline LR, decision tree classifiers (DT), support vector classifiers (SVC), random forest classifiers (RF), linear discriminant analysis (LDA), K nearest neighbour classifiers (KNN) and extreme gradient boosting (XGB).

Background: We aimed to elucidate the potential correlation between single-nucleotide polymorphisms (SNPs) in miRNA machinery genes and colorectal cancer (CRC) risk in an Iranian cohort.
Methods: We conducted a robust case-control study involving 507 participants, which included 213 patients diagnosed with CRC and 294 healthy controls at Research Institute for Gastroenterology and Liver Diseases in Tehran Province, Iran in 2018. The study focused on genotyping four specific SNPs, (rs14035), (rs197412), (rs2740348), and (rs3742330), using advanced ARMS-PCR and Tetra-primer ARMS-PCR techniques.
