مولف: Shima Hadifara, b, 1, Leila Shamkhalia, b, 1, Mansour Kargarpour Kamakolia, b, Shayan Mostafaeic, d, Sharareh Khanipoura, Noormohamad Mansoorie, Abolfazl Fateha, b, Seyed Davar Siadata, b, Farzam Vaziria, b, ⁎

خلاصه: Objectives: Evaluation of the genetic diversity of Mycobacterium tuberculosis (M.tb) and determining if the association between a specific genotype and the site of infection is crucial. Accordingly, the current study aimed at comparing predominant M.tb genotypes in pulmonary (PTB) and extrapulmonary tuberculosis (EPTB) isolates circulating in the capital of Iran. Methods: The genetic diversity of culture-confirmed PTB and EPTB isolates were evaluated by Spoligotyping and MIRU-VNTR (mycobacterial interspersed repetitive-unit–variable-number tandem-repeat) typing methods. Genotyping data were analyzed ... سال انتشار: 2019

خلاصه: Lung cancer, the leading cause of cancer mortality, needs urgent development of newly qualified diagnostic and therapeutic biomarkers. Recently, Human Endogenous Retroviruses (HERVs) have been introduced for cancer diagnosis. In this case-control study, we have collected blood samples from 60 lung cancer patients and 20 healthy controls. Quantitative gene expression analysis of various HERV env genes, including HERV-R, HERV-H, HERV-K, and HERV-P was performed by real-time PCR. Results indicate that expression of all four ... سال انتشار: 2018
 

Curcumin reduces the expression of interleukin 1b and the production of interleukin 6 and tumor necrosis factor alpha by M1 macrophages from patients with Behcet's disease

مولف: Mohammad Taghi Palizgira, Maryam Akhtaria, b, Mahdi Mahmoudia , Shayan Mostafaeia, Alireza Rezaiemaneshc and Farhad Shahrama

خلاصه: Objective: Behcet's disease (BD) is an auto-inflammatory disorder. Curcumin as a bio-active agent has anti-inflammatory properties. Effects of curcumin on the pathogenesis of BD are still not clear. In this study, we investigated the effect of curcumin on the inflammatory cytokines expression and production in M1 macrophages from BD patients compared with healthy controls. Methods: Monocytes were collected from 10 healthy controls and 20 active BD patients, differentiated to macrophages by macrophage-colony stimulating factor for ... سال انتشار: 2018
 

Cochlea CT radiomics predicts chemoradiotherapy induced sensorineural hearing loss in head and neck cancer patients: A machine learning and multi-variable modelling study

مولف: Hamid Abdollahia, Shayan Mostafaeib, Susan Cheraghic, d, Isaac Shirie, f, Seied Rabi Mahdavia, d, ⁎, Anoshirvan Kazemnejadb, ⁎

خلاصه: Objectives: Immediately or after head-and-neck (H&N) cancer chemoradiotherapy (CRT), patients may undergone significant sensorineural hearing loss (SNHL) which could affect their quality of life. Radiomic feature analysis is proposed to predict SNHL induced by CRT. Material and methods: 490 image features of 94 cochlea from 47 patients treated with three dimensional conformal RT (3DCRT) for different H&N cancers were extracted from CT images. Different machine learning (ML) algorithms and also least absolute shrinkage and selection ... سال انتشار: 2018
 

Worldwide prevalence of viral infection in AECOPD patients: A metaanalysis

مولف: Habib Jafarinejada, Mohsen Moghoofeib, Shayan Mostafaeic, Jafar Salimiand, Sadegh Azimzadeh Jamalkandid, ∗, Ali Ahmadia, ∗∗

خلاصه: Background and objective: Chronic obstructive pulmonary disease (COPD) is a chronic progressive lung disease. On the other hand, viral infections of the airway are associated with the acute exacerbations of COPD. A systematic review and meta-analysis were performed to determine the prevalence rate of viral infections in acute exacerbations of COPD patients. Methods: PubMed database was systematically searched for population-based prevalence studies (1930–2017). Fixed and random effects models were used for estimation of summary effect-sizes. ... سال انتشار: 2017
 

Molecular investigation of virulence factors of Brucella melitensis and Brucella abortus strains isolated from clinical and non-clinical samples

مولف: Reza Mirnejad a, Faramarz Masjedian Jazi b, Shayan Mostafaei c, d, Mansour Sedighi

خلاصه: Brucella is zoonotic pathogen that induces abortion and sterility in domestic mammals and chronic infections in humans called Malta fever. It is a facultative intracellular potential pathogen with high infectivity. The virulence of Brucella is dependent upon its potential virulence factors such as enzymes and cell envelope associated virulence genes. The aim of this study was to investigate the Brucella virulence factors among strains isolated from humans and animals in different parts of Iran. ... سال انتشار: 2017
