    Abstract Aeolian dust emission is a serious environmental hazard in central Iran. We attempted to map the dust emission prone (DEP) areas in this region of Iran using the most accurate model among the random forest (RF), conditional RF (CRF), parallel RF (PRF), and extremely randomized trees (ERT) models. These models were evaluated using the Taylor diagram, Nash Sutcliffe coefficient, and Kling–Gupta efficiency. The generated map of DEP areas was also validated based on an aerosols optical depth (AOD) dataset. The Shapely values were used to determine the contribution of factors controlling dust events in DEP areas. The high performance and reliability of the ERT model for mapping DEP territories were confirmed by both error assessment statistics and reclassified AOD map. Using the ERT-generated map, five dust generation susceptibility classes including very low (20.16%), low (19.99%), moderate (19.82%), high (24.11%), and very high (15.92%) were identified in the study region. Drought severity, solar radiation, soil moisture, geology, soil sand content, bulk density, vegetation cover, land use, and slope were detected as the key features controlling dust emissions in central Iran. These results are useful for developing programs to reduce dust emissions hazards in DEP areas, particularly in central Iran.

    Abstract Vocal fold paralysis (VFP) can happen in various conditions due to mediastinal LADs, however no study has proposed anthracosis as an etiology. Here we discussed the chest CT features of anthracosis related LADs causing VFP. Among 41 cases of pulmonary anthracosis, 10 had VFP that all were presented with hoarseness. The paralysis was unilateral (left side) in all cases. Extra-nodal infiltration and conglomeration of lymph nodes were significantly higher in patients with paralysis. Left paratracheal, pre-vascular, and aortopulmonary window lymph nodes were seen in all patients. We propose that mediastinal LADs secondary to anthracosis could be a reason for left side VFP.

    Abstract Background: Diffusion-weighted imaging (DWI) is one of methods in evaluation of breast lesions. We aimed to investigate the apparent diffusion coefficient (ADC) values in breast tumors and their accuracy in differentiating benign versus malignant lesions. Methods: In this cross-sectional study, 72 patients with 88 breast lesions were investigated by 1.5-T breast MRI from 2015 to 2017 in Athari Imaging Center in Tehran, Iran. Nearly all patients has undergone histopathology evaluation. One small region of interest (ROI) were placed on the most restricted region inside the solid part on the ADC map. Care was taken to avoid cystic or necrotic, fatty regions and hematoma inside the mass. A large round ROIs were placed in healthy fibroglandular tissue of contralateral breast ADC values were measured and compared in normal breast tissue and in most restricted parts of breast lesions (mass and non-mass). After determining cut-off for differentiation of benign and malignant lesions, sensitivity, specificity, accuracy, positive predictive value and negative predictive value were calculated. Results: Mean age of patients was 43.3 years. The average tumor size of benign and malignant lesions were calculated 26.0 mm, 35.3 mm respectively and 23 mm and 46 mm in mass and non-mass respectively. Invasive ductal carcinoma include the majority of pathology result (in 37.5% of the patients). Our results revealed that the measured ADC values in normal breast tissue were higher than breast lesions (P≤0.01). Mean ADC value in benign lesions was 1.40×10-3 mm²/s and for malignant lesion was 1.08×10-3 mm²/s. ADC value in the normal breast tissue was 1.79×10-3 mm2/s and was significantly higher than ADC value of breast lesions (benign and malignant). Cut-off value in non-mass was not valid, but in mass was 1.19×10-3 mm²/s with sensitivity, specificity, positive predictive value, negative predictive and accuracy of 89.7%, 83.8%, 87.5%, 86.6%, and 87.1% respectively. Conclusion: In DWI imaging, ADC value can differentiate benign and ...

    Abstract Achondrogenesis is a very rare lethal skeletal disorder. Here we describe a case of prenatally diagnosed achondrogenesis type Ⅱ in a 28 year-old woman at (17+4) wk. She had history of 5 first trimester missed abortions. The couple is consanguineous. Ultrasonography showed extreme micromelia, short neck and trunk, large head and prominent abdomen. Delayed ossification in sacral bones was detected and ossification of pubic rami was poor. There were associated large cystic hygroma, anasarca and also high occipital cephalocele. Posterior fossa was normal. Mild hypothelorism, depressed nasal bridge, low set ear and mild retrognathia were identified too. Amniocentesis result was compatible with a normal female fetus. Post mortem whole body radiography confirmed the diagnosis. To our knowledge, this is the second case report with association of cephalocele and achondrogenesis type Ⅱ.

    Abstract Objective(s):The aim of this study was to compare the chondrogenic induction potential of Piascledine and TGF-β1 on adipose-derived stem cells (ADSCs) in fibrin and fibrin-alginate scaffolds. Materials and Methods: Human subcutaneous adipose tissues were harvested from three patients who were scheduled to undergo liposuction. Isolated ADSCs were proliferated in a culture medium. Then, the cells were seeded in fibrin or fibrin-alginate scaffolds and cultured for 14 days in a chondrogenic medium containing Piascledine, TGF-β1, or both. The rate of cell proliferation and survival was evaluated by using MTT [3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide] assay and the rate of the expression of type II collagen, aggrecan, and type X collagen genes was evaluated by real-time polymerase chain reaction (real-time PCR) method. Results: The MTT results showed that Piascledine is able to enhance the proliferation and survival of ADSCs in fibrin scaffolds in comparison to other groups (P
