    A factorial experiment with the split plot arrangement using the complete randomized block design with three replications was carried out adjacent to the Agriculture School of Shahrood University of Technology in 2010-2011 to study the effects of sulfur and Thiobacillus application and zinc and molybdenum sprays on some traits of green beans. The treatments included three levels of sulfur (zero, 100 kg/ha of sulfur powder, and 100 kg/ha of sulfur powder + Thiobacillus bacteria) as the main factor, and three levels of zinc spray (0, 5, and 10g/l) and two levels of molybdenum spray (0 and 0.5 g/l) as the sub-main factors. The treatments that included sulfur were applied before seeding. Zinc (using zinc sulfate) and molybdenum (using sodium molybdate) were sprayed during the growing season and 5 weeks after planting. Results showed the treatment of applying sulfur at 100 kg/hectare and Thiobacillus bacteria increased leaf fresh and dry weights by 57 and 54%, mean pod length by 14%, and number of lateral branches by 25% compared to the control. Moreover, this treatment increased pod fresh and dry weights by 41.6 and 42.11%, respectively, compared to the treatment of not applying sulfur, and improved yield by 42% compared to the control. Considering the results concerning yield in response to sulfur, zinc, and molybdenum, it can be said that application of sulfur and Thiobacillus together with zinc spray can be very useful in growing green beans

Is Herpes Simplex virus (HSV) a sign of Encephalitis in Iranian Newborns? Prevalence of HSV Infection in Pregnant Women in Iran: A Systematic Review and Meta-Analysis. Iran J Child Neurol.Spring 2017; 11(2):1-7. AbstractObjectiveHerpes Simplex virus (HSV) is one of the most common sexually transmitted diseases in the world. This study aimed to determine the prevalence of herpes simplex virus in pregnant women in Iran.Materials & MethodsA systematic literature review was conducted to study the HSV subtypes in Persian and English papers through several databases. We searched Pub Med, Scopus, Ovid, Science Direct and national databases as Magiran, Iranmedex and Science Information Database (SID) up to October 2015. Random-effects model were applied to calculate the pooled prevalence of HSV subtypes.ResultsFive eligible studies were identified, including 1140 participants. The pooled prevalence of HSV infection in pregnant women was 0.64% (95% CI: 0.10- 1.18) in Iran. The pooled prevalence of studies on both HSV-1 and HSV-2 was 0.91% (CI: 0.81-1.02) and studies on only HSV-2 was 0.23% (CI: -0.61-0.63), respectively.ConclusionThe prevalence of HSV infection in pregnant women in Iran was higher. HSV infection of the central nervous system, especially with HSV-2, can also cause recurrent aseptic meningitis and monophasic, as well as radiuculitis or myelitis. The performance of screening to detect infection in pregnant women can play an important role in the prevention and treatment of patients and help to prevent the transmission of HSV infection to infants in Iran.References 1.Xu F, Sternberg MR, Kottiri BJ, McQuillan GM, Lee FK, Nahmias AJ, et al.

    Background: Systemic lupus erythematosus (SLE) is a chronic inflammatory disorder that affects the kidney in around 50% of patients Objectives: The aim of this study was to assess CD147 expression with various pathologic lesions, biochemical and demographic data in patients with classes III and IV lupus nephritis. Patients and Methods: These patients with lupus nephritis classes II and IV by renal biopsy and pathology were enrolled in this study. The strength of CD147 staining on tubules, Bowman’s capsules, vessels and tuft of glomeruli was expressed as proportion of involvement. Results: In this study, 23 renal biopsies for lupus nephritis of classes III and IV (documented by immunofluorescence and light microscopic studies) were included. No significant difference of CD147 staining between classes was detected (P > 0.05). In addition, proportion of proteinuria was not related to CD147 staining in tubules, Bowman’s capsules, vessels and tuft of glomeruli in classes III and IV lupus nephritis (P > 0.05). There was no significant association of CD147 staining in tubules, Bowman’s capsules and vessels with serum creatinine (P > 0.05). However, an association between CD147 staining in tuft of glomeruli with serum creatinine was detected (r=0.623, P = 0.002). None of chronicity or activity percent of glomerular involvement in two classes of III or IV had a significant association with CD147 staining (P > 0.05). Conclusions: The significant association between CD147 staining in glomeruli with serum creatinine in lupus nephritis of classes III and IV revealed that inflammation at this area may have prognostic implication

    Evaluation of protective effects of non-selective cannabinoid receptor agonist WIN 55,212-2 against the nitroglycerine-induced acute and chronic animal models of migraine: A mechanistic study

    Get PDF
    Aim: Migraine is a neurological debilitating disorder. Previous studies have shown that cannabinoid receptor agonists have analgesic effects in various models of pain. In this study, therefore, we investigated anti-nociceptive effects of WIN 55,212-2, and the role of either CB1 or CB2 receptors in nitroglycerine (NTG)-induced animal model of migraine. Methods: The present study was conducted on both male and female rats receiving NTG (10 mg/kg, i.p.) to induce acute (single dose of NTG) and chronic (repetitive doses of NTG) models of migraine. Additionally, three groups received WIN 55,212-2 (0.33, 1, 3 mg/kg, i.p.) 45 min before behavioral tests. Additionally, AM251 and AM630 (CB1 and CB2 receptor antagonist, respectively, 1 mg/kg, i.p.) were used to evaluate the possible involvement of CB1 and CB2 receptors during the protective effects of WIN 55,212-2. Key findings: We found that NTG (10 mg/kg, i.p.) in both acute and chronic models increased sensitivity to pain. In acute model, we found that WIN 55,212-2 (almost high doses) decreases the level of pain mainly through CB1 receptor due to CB1 antagonist abrogates its protective effects, however, in formalin test CB2 receptors also had crucial roles in both phases at 3 mg/kg of WIN 55,212-2. In chronic model, WIN 55,212-2 (0.33, 1 and 3 mg/kg) significantly attenuated NTG-induced hyperalgesia through both CB1 and CB2 receptors. Significance: Our data supported the argument that activation of CB1 and CB2 receptors by WIN 55,212-2 may be considered a new medication for migraine, however in lack of each receptor leads to different responses from deletion to the reduction of analgesic effects. © 2019 Elsevier Inc

    Clinical Characteristics of Fatal Cases of COVID-19 in Tabriz, Iran: An Analysis of 111 Patients

    Get PDF
    Introduction: The rapid worldwide spread, in addition to the morbidity and mortality associated with the novel coronavirus disease 2019 (COVID-19), have raised concern throughout the world. Identifying the characteristics of patients who died of COVID-19 is essential to implement preventive measures. Objective: We aimed at investigating these characteristics among the Iranian population in Tabriz. Methods: In this case series, we analyzed clinical characteristics, laboratory parameters, and imaging findings of 111 patients with a reverse transcriptase-polymerase chain reaction (RT-PCR)-confirmed COVID-19 diagnosis who died during hospitalization. The studied patients had been admitted to the hospital between February 2020 and May 2020. Results: The median age of patients was 73 years (IQR, 62-82 years) and approximately 70% of them were male. The median oxygen saturation on admission was 88% (IQR, 80-92%) and dyspnea, cough, and fever were the most common presenting symptoms. Among comorbidities, diabetes, hypertension, and cardiovascular diseases were more frequently observed among patients who had a fatal outcome. While ground-glass opacity was the most commonly reported finding on chest computed tomography, 5% of the patients had no abnormal finding on imaging. Chloroquine was the most frequently used medication for treatment. Conclusion: Our results showed that the majority of COVID-19 deaths occurred in male elderly with decreased levels of oxygen saturation and elevated levels of lactate dehydrogenase and erythrocyte sedimentation rate on admission

    Immune checkpoints in targeted-immunotherapy of pancreatic cancer: New hope for clinical development

    Get PDF
    Immunotherapy has been recently considered as a promising alternative for cancer treatment. Indeed, targeting of immune checkpoint (ICP) strategies have shown significant success in human malignancies. However, despite remarkable success of cancer immunotherapy in pancreatic cancer (PCa), many of the developed immunotherapy methods show poor therapeutic outcomes in PCa with no or few effective treatment options thus far. In this process, immunosuppression in the tumor microenvironment (TME) is found to be the main obstacle to the effectiveness of antitumor immune response induced by an immunotherapy method. In this paper, the latest findings on the ICPs, which mediate immunosuppression in the TME have been reviewed. In addition, different approaches for targeting ICPs in the TME of PCa have been discussed. This review has also synopsized the cutting-edge advances in the latest studies to clinical applications of ICP-targeted therapy in PCa
