Growth, yield index, and photosynthesis traits of sweet pepper grown in vermicompost inoculated with Arbuscular mycorrhiza

Iran agricultural research (2018)

Maryam Haghighi Mohammad Reza Barzegar

ABSTRACT- The aim of this study was to investigate the effects of “Arbuscular mycorrhizal fungi” (AM fungi) density and different growing media on the growth, photosynthesis parameters and yield of sweet pepper under greenhouse conditions. The experiment was conducted as a factorial plan based on control randomized design (CRD ( by using three growing media, Perlite (PR) and cocopeat (Co) (PR50:Co50 V:V) (C), PR25:Co50: vermicompost (V) 25 (C+V25) and PR25:Co25: V50 (C+V50), and three levels of AM fungi inoculation (0, 1000 and 2000 spores) with three replications. Results indicated that AM fungi inoculation and mixture of vermicompost increased shoot and root fresh weights,Total Suspended Solids (TSS), fruit fresh and dry weights in the C+V50 compared to other treatments. Fruit yield increased more than 100 and 94.95% with AM-fungi inoculation with 2000 spores at C+V25 and V50 treatments, respectively. Mycorrhiza dependency decreased with high application rate of vermicompost, and vermicompost dependency was the highest in non-inoculated plants. With AM-fungi inoculations, the chlorophyll level (SPAD values) was increased in C+V25 by 100%. Photosynthesis rate was increased in C+V25×M1 significantly compared to other treatments. Nitrogen, phosphorus, and potassium concentrations significantly increased by mycorrhiza inoculation in the high vermicompost ratio.

Comparing Cox Model and Parametric Models in Estimating the Survival Rate of Patients with Prostate Cancer on Radiation Therapy

Majallah-i dānishgāh-i ̒ulūm-i pizishkī-i Māzandarān/Journal of Mazandaran University of Medical Sciences (2013)

Ahad Alizadeh Reza Ali Mohammadpour Mohammad Reza Barzegar

Background and purpose: Prostate cancer is the second most common malignant cancer in men and radiotherapy is one of the treatments for this disease. The aim of this study was to determine the effect of demographic, clinical and pathology factors in survival rate of patients on radiotherapy and comparing different survival models to determine an efficient model. Materials and methods: In a historical cohort study 422 patients with prostate cancer were included. The subjects were chosen among those undergone radiotherapy and were followed up during 2007-2012 in the Cancer Institute of Tehran University. Effects of various factors on the survival rate of radiation treatment were determined using Cox model and three parametric models including log-normal, log-logistic and Weibull. We used AIC criteria and also standardized variability of regression coefficient. To analyze the data the Survival was applied in R version 2.14.1. Results: Patients who received higher total dose of radiation and those undergone hormone therapy simultaneously, indicated higher survival rate (both p≤0.001). Univariate and multivariate models based on AIC criteria were more efficient than the Cox model for log-normal, log-logistic and Weibull, respectively. The findings were confirmed by the standardized variability. Conclusion: Parametric models in univariate and multivariate models showed higher efficiency compared with Cox model.

TREATMENT OF A PIGMENTED HYPERTROPHIC SCAR BY LOW-LEVEL LASER THERAPY (LLLT): A CASE REPORT

Journal of lasers in medical sciences (2010)

Hamideh Moravvaej Lisa Daneshvar Mohammad Saeedi Mohammad Reza Barzegar

A hypertrophic scar is defined as an excess healing response that is a dilemma for physicians. Several therapies are available: intralesional corticosteroids, topical treatments, cryotherapy, surgery, radiation, silicone gel dressing and laser therapy.Pulsed-dye, Nd-Yag and CO2 lasers have been used for treatment of keloids and hypertrophic scars but recurrence is common. Recently Low-Level Laser Therapy(aluminum-gallium-arsenide (AlGaAs) Diode 980nm, red light (Mustung, KLO4,Helium Neon 630 nm) and blue light LED lasers have been used for closure of wounds. The aim of this report is to show the effectiveness of these lasers for the treatment of a hypertrophic scar on the forearm of a 40 year-old woman due to burning by gas explosion.

Fusion TRV limiter a solution to modify interrupting characteristics of CBs with presence of resonance type SFCL

Mohammad Reza Barzegar Mohsen Niasati

Applying FCLs in power system lead to suppress short-circuit level and burden of CBs. Alongside with their astounding advantages; it is possible that the FCLs have destructive effects on interrupting characteristics of CBs such as TRV characteristics. Among various topologies introduced for FCLs, Resonance type SFCL affects incredibly on TRV characteristics and causes severe interrupting conditions for CB. In this paper to modify TRV characteristics of CBs with presence resonance type SFCL, Fusion TRV Limiter which consists of parallel metal oxide surge arrester and capacitor between CB terminals is proposed. Proposed method is evaluated under different conditions in EMTP-RV® environment with selecting of reliable parameters for FCL and system. The proposed method is finally compared with other methods; obtained results show that the simple proposed method has high performance to modify TRV characteristics.

Ultrasound Guided Port-A-Cath Implantation

Surgical Science (2014)

Hossein Hemmati Mohammad Sadegh Esmaeli Delshad Mohammad Reza Barzegar Ali Babaei Jandaghi Behruz Najafi

Purpose: The use of port catheters is well accepted in the management of patients with malignancy. In this study, we compare the technical success and the complication rates of ultrasound guided Port-A-Cath implantation with doing this procedure by using the anatomical landmark method. Methods: In a retrospective study, from 2006 to 2009, medical files of 104 patients who had undergone Port-A-Cath implantation were reviewed. The indication for port catheter implantation was malignancy in all cases. Among our patients, Port-A-Cath implantation was done in 63 patients by using landmark method and in 41 patients by guidance of ultrasound. All patients had been observed for complications including pain, port infection, and port thrombus, thrombus of central veins, skin necrosis, and success in using of Port-A-Cath for at least one month following the procedure, in the vascular clinic. Results: in landmark method group, 2 catheters were non-functional just after placement (3.2%) while all Port-A-Caths in ultrasound-guided group were functional. Ten patients (15.9%) in land mark group and 1 patient (2.4%) in ultrasound-guided group were complicated. The difference between complication rate in anatomic landmarks method and ultrasound-guided method was statistically significant (p There was no significant difference in two groups in duration of port placement (p
