    Takfiri terrorism, as a political phenomenon for those claiming power in form of religious groups is expanding in Islamic countries and has become the greatest challenge for the Islamic world. Misuse of jurisprudential rules named "Tatarros" and "Avoidance of Taghut" is the most abject mental and practical approach that is being practised by this group. The present article adopts library and descriptive-analytical methods to examine major principles of Takfiri terrorism from the perspective of jurisprudence and law. The purpose of this study is to prove that the main principles of Takfiri terrorism, namely the jurisprudential rule of "Tatarros" and "Avoidance of Taghut", seek aggression and other forms of terror in Islamic countries and that the killing of Muslims by Takfiris is unrelated to the rule of Tatarros. The question is what conditions govern these rules according to Islamic jurists and whether these rules entail suicide attacks and the killing of civilians

    Chlorophenols as priority pollutants are toxic. These acidic organic compounds cause digestive disorders, liver damage, and cancers. The aim of this study is Ortho- chlorophenol removal using zero-valent iron nanoparticles modified clay. In this experimental study, the clay soil was sampled from the mountains of Shah Murad, Rafsanjan, Iran. Then it was treated with hydrochloric acid. In the next step, the clay was modified with ferrous sulfate in the presence of the N2 gas to prepare magnetic clay. Then, the prepared adsorbent was used to remove o-chlorophenol as a function of pH, adsorbent dose and contact time. In addition, adsorption isotherms and kinetics were determined. The findings of the present study showed that the removal efficiency obtained by the iron nanoparticles carrying clay was higher than that of the raw clay. The highest removal efficiency (91.3 %.) was obtained for pH 4. The o-CP removal efficiency by the modified clay increased from 35.9 to 82.7 as the adsorbent dosage is increased from 0.05 to 1 g after 120min contact time. The Langmuir isotherm model and the second-order kinetic model provided the best fit to the experimental data compared to other studied models. The results showed that the modified adsorbent could be used an effective and readily available low-cost adsorbent for the removal of chlorophenols in industrial applications

    Background: By evaluating the psychometric properties of the Persian version of the Internet Addiction Test-Social Networking Sites version (IAT-SNS) in a sample of Iranian university students, this study investigated the dimensionality of SNS addiction for the first time. Methods: A total of 620 SNS users (414 women) participated in the study. The study questionnaire comprised demographic information, SNS usage patterns, the IAT-SNS, and the Bergen Social Media Addiction Scale (BSMAS). Findings: Exploratory factor analysis (EFA) identified the 3-factor structure of the IAT-SNS, namely ‘Lack of Control’, ‘Emotional and Relational Conflict’, and ‘Preference for online relationships’ that explained 54% of the total variance. Confirmatory factor analysis (CFA) verified the current model. Problematic users on average exhibited higher scores on the whole IAT-SNS and each of the 3 factors as compared to non-problematic users. The IAT-SNS and its factors showed good internal consistency, and strong convergent and concurrent validity. Conclusion: The Persian version of the IAT–SNS is valid and reliable, and is applicable for measuring the 3 dimensions of SNS addiction among students

    Background: Ursane triterpenoids could be considered as novel multi-target therapeutic anti-cancer agents. Salvurmin A and Salvurmin B are novel cytotoxic ursane triterpenoids isolated from the aerial parts of Salvia urmiensis, an endemic plant species of Iran. Methods: In this study, we assessed cytotoxicity of these compounds against two human cancer cell lines and one human normal cell line and investigated its mechanism via apoptosis and cell cycle arrest. Results: Salvurmin A and B showed the most cytotoxic effect on A549 cells compared to other studied cancer cells. IC50 values for Salvurmin A and B against A549 cells were 35.6 ± 1.5 and 19.2 ± 0.8 µM, respectively. Based on annexin V staining, both of these compounds significantly induced apoptosis in A549 cells. Moreover, these two compounds significantly increased cell accumulation in G2/M and decreased the number of cells in G0/G1 phases in A549 cells in a dose-dependent manner. Conclusion: Based on the results Salvurmin B can be considered as potential candidate for further studies against human lung carcinoma

    Invasive Fusarium rhinosinusitis in COVID-19 patients: report of three cases with successful management

    Get PDF
    Invasive fungal rhinosinusitis (IFRS) is a life-threatening infection that can occur in immunocompromised patients, including those with COVID-19. Although Mucorales and Aspergillus species are the most common causes of IFRS, infections caused by other fungi such as Fusarium are rare. In this report, we present three cases of proven rhinosinusitis fusariosis that occurred during or after COVID-19 infection. The diagnosis was confirmed through microscopy, pathology, and culture, and species identification of the isolates was performed by DNA sequencing the entire ITS1-5.8 rRNA-ITS2 region and translation elongation factor 1-alpha (TEF-1α). Antifungal susceptibility testing was conducted according to CLSI guidelines. The causative agents were identified as Fusarium proliferatum, F. oxysporum + Aspergillus flavus, and F. solani/falciforme. Treatment involved the administration of antifungal medication and endoscopic sinus surgery to remove the affected mucosa, leading to the successful resolution of the infections. However, one patient experienced a recurrence of IFRS caused by A. flavus 15 months later. Early diagnosis and timely medical and surgical treatment are crucial in reducing mortality rates associated with invasive fusariosis. Additionally, the cautious use of corticosteroids in COVID-19 patients is highly recommended

    In the field of rare diseases, progress in molecular diagnostics led to the recognition that variants linked to autosomal-dominant neurodegenerative diseases of later onset can, in the context of biallelic inheritance, cause devastating neurodevelopmental disorders and infantile or childhood-onset neurodegeneration. TOR1A-associated arthrogryposis multiplex congenita 5 (AMC5) is a rare neurodevelopmental disorder arising from biallelic variants in TOR1A, a gene that in the heterozygous state is associated to torsion dystonia-1 (DYT1 or DYT-TOR1A), an early-onset dystonia with reduced penetrance. While 15 individuals with TOR1A-AMC5 have been reported (less than 10 in detail), a systematic investigation of the full disease-associated spectrum has not been conducted. Here, we assess the clinical, radiological and molecular characteristics of 57 individuals from 40 families with biallelic variants in TOR1A. Median age at last follow-up was 3 years (0-24 years). Most individuals presented with severe congenital flexion contractures (95%) and variable developmental delay (79%). Motor symptoms were reported in 79% and included lower limb spasticity and pyramidal signs, as well as gait disturbances. Facial dysmorphism was an integral part of the phenotype, with key features being a broad/full nasal tip, narrowing of the forehead and full cheeks. Analysis of disease-associated manifestations delineated a phenotypic spectrum ranging from normal cognition and mild gait disturbance to congenital arthrogryposis, global developmental delay, intellectual disability, absent speech and inability to walk. In a subset, the presentation was consistent with fetal akinesia deformation sequence with severe intrauterine abnormalities. Survival was 71% with higher mortality in males. Death occurred at a median age of 1.2 months (1 week - 9 years) due to respiratory failure, cardiac arrest, or sepsis. Analysis of brain MRI studies identified non-specific neuroimaging features, including a hypoplastic corpus callosum (72%), foci of signal abnormality in the subcortical and periventricular white matter (55%), diffuse white matter volume loss (45%), mega cisterna magna (36%) and arachnoid cysts (27%). The molecular spectrum included 22 distinct variants, defining a mutational hotspot in the C-terminal domain of the Torsin-1A protein. Genotype-phenotype analysis revealed an association of missense variants in the 3-helix bundle domain to an attenuated phenotype, while missense variants near the Walker A/B motif as well as biallelic truncating variants were linked to early death. In summary, this systematic cross-sectional analysis of a large cohort of individuals with biallelic TOR1A variants across a wide age-range delineates the clinical and genetic spectrum of TOR1A-related autosomal-recessive disease and highlights potential predictors for disease severity and survival
