    Abstract Extramedullary plasmacytoma is a rare and unusual complication of multiple myeloma (MM). Some sites for the extramedullary involvement of MM are the liver, spleen, lymph node, lung, and skin. Renal failure is another complication of MM due to myeloma kidney, uric acid nephropathy, hemoconcentration, or light chain disease. This study reported a case of MM with unusual presentation. She was a 61-year-old woman who was admitted to the internal ward due to severe renal failure, anemia, mild proteinuria, hypertension, thrombocytopenia, and soft tissue mass in both lungs in the spiral computed tomography (CT) scan. In the skull X-ray, there was not any lytic lesion. Further, plasma cells greater than 30% were observed in serum protein electrophoresis pick of gamma region and in the bone marrow aspiration, so the final diagnosis of the patients was MM with extramedullary plasmacytoma.

    Abstract Objective Rice is one of the most important crops in the world, which occupies a large area of arable land. Blast disease is one of the most important and destructive rice diseases, which reduces production of this product. Due to environmental pollution caused by overuse of fungicides to control this disease and on the other hand, the pathogen resistance to these chemicals, development of better and healthier strategies to control this pathogen is necessary. Biological control of plant diseases using antagonists can be a promising alternative method. Materials and methods In this study, indirect effect of Trichoderma harzianum fungus on pathogenic fungus, Magnaporthe oryzae, under greenhouse conditions was investigated by induction of systemic resistance in susceptible Tarom cultivar. For this purpose, expression of several important defense genes was investigated using real-time qPCR technique in plants symbiont with Trichoderma compared to control plants (without Trichoderma) at different times after infection with pathogenic fungi. Results The results showed increasing expression level of NPR1, PR2 and PR3 genes after pathogen inoculation in plants symbiont with Trichoderma compared to the control plants that there was statistically significat difference about PR2 and PR3 genes. Nevertheles in a number of times, there was no significant difference in expression level of the evaluated genes between two treatments. Examination of various morphological traits such as root, stem and leaf dry weight, root length, stem diameter and plant height showed an increase in plants symbiont with Trichoderma compared to control plants (without Trichoderma), although this difference was not significant about these traits except for plant height. Chlorophyll a and b levels were also measured as physiological traits in both treatments. Although amount of chlorophyll a was higher in plants symbiont with Trichoderma than control plants, but no significant difference was observed. Phenotypic study of interaction of rice plant and ...

    Abstract Abstract Inspired by the information theory, a new concept of re-programmable encrypted graphene-based coding metasurfaces was investigated at terahertz frequencies. A channel-coding function was proposed to convolutionally record an arbitrary information message onto unrecognizable but recoverable parity beams generated by a phase-encrypted coding metasurface. A single graphene-based reflective cell with dual-mode biasing voltages was designed to act as “0” and “1” meta-atoms, providing broadband opposite reflection phases. By exploiting graphene tunability, the proposed scheme enabled an unprecedented degree of freedom in the real-time mapping of information messages onto multiple parity beams which could not be damaged, altered, and reverse-engineered. Various encryption types such as mirroring, anomalous reflection, multi-beam generation, and scattering diffusion can be dynamically attained via our multifunctional metasurface. Besides, contrary to conventional time-consuming and optimization-based methods, this paper convincingly offers a fast, straightforward, and efficient design of diffusion metasurfaces of arbitrarily large size. Rigorous full-wave simulations corroborated the results where the phase-encrypted metasurfaces exhibited a polarization-insensitive reflectivity less than −10 dB over a broadband frequency range from 1 THz to 1.7 THz. This work reveals new opportunities for the extension of re-programmable THz-coding metasurfaces and may be of interest for reflection-type security systems, computational imaging, and camouflage technology.

    Abstract Background: Arteriovenous fistula (AVF), permanent catheter (PC), and vascular graft are three vascular access types used for hemodialysis procedure. Due to insufficient reliable information on the comparison between AVF and PC, this study was conducted to compare AVF and PC regarding dialysis adequacy. Materials and Methods: This prospective study was carried out from March, 2013 to September, 2013. In this study, 76 hemodialysis patients were enrolled and assigned to two unequal groups of AVF and PC. Before and after the dialysis session, blood samples were taken for laboratory examinations and measurement of urea reduction ratio (URR) and Kt/V. The patients were followed up for six months, and then laboratory examinations were repeated. Results: Of the 76 hemodialysis patients, 30 had AVF and others PC. During the 6-month follow-up, 24 patients in PC group but only one patient in AVF group showed infection (P = 0.006), while in each group, three cases of thrombosis were seen (P = 0.58); however, catheter dysfunction was seen in 13 patients of PC group but no patients of AVF group (P = 0.004). There was no difference between the two groups in Kt/V and URR at the beginning of the study; however, after six months, Kt/V and URR were greater in AVF group (P < 0.05). Conclusions: In addition to some advantages of AVF over PC, such as lower rate of infection and thrombosis, we also found better dialysis adequacy in AVF group. We recommend that AVF be created in all of patients with chronic kidney disease who are candidates for hemodialysis.

    Abstract The high prevalence rate in conjunction with the long latency period made prostate cancer (PCa) an attractive and reasonable candidate for preventive measures. So far, several dietary and nutritional interventions have been implemented and studied with the aim of preventing the development or delaying the progression of PCa. Calorie restriction accompanied by weight loss has been shown to be associated with decreased likelihood of aggressive PCa. Supplements have played a major role in nutritional interventions. While genistein and lycopene seemed promising as preventive agents, minerals such as zinc and selenium were shown to be devoid of protective effects. The role of vitamins has been widely studied, with special emphasis on vitamins with antioxidant properties. Data related to Vitamin A and Vitamin C were rather controversial and positive effects were of insignificant magnitude. Vitamin E was associated with a decreased risk of PCa in high-risk groups like smokers. However, when it comes to Vitamin D, the serum levels might affect the risk of PCa. While deficiency of this vitamin was associated with increased risk, high serum levels imposed the risk of aggressive disease. Despite the seemingly promising effects of dietary measures on PCa, no firm recommendation could be made due to the limitations of the studies and evidence. However, the majority of these advices could be followed by the patients with the intent of living a healthy lifestyle.

    Abstract Introduction: Hospital mortality of Intensive Care Unit (ICU) patients has shown correlation with severity of the Acute Kidney Injury (AKI). There are a few studies regarding short term or long term morbidity and mortality of the ICU patients after hospital discharge. Aim: The aim of the study was to evaluate predisposing factors, in hospital mortality and six months followup of the ICU admitted patients in two general hospitals. Materials and Methods: This prospective descriptive study was carried out on 520 ICU admitted patients, in Hajar and Kashani Hospitals, Shahrekord, Iran. The patients were evaluated for causes of hospital admission and inpatient and outpatient mortalities three and six months after discharge. Data were collected and analyzed by SPSS version 19.0 through Spearman’s and Pearson’s correlation tests. Results: Of 520 patients under study, 350 were male and others were female. Mean age of the patients was 55.06±23.3 years. During ICU admission, AKI developed in 147 (28.2%) patients. Based on RIFLE criteria, in the patients with AKI, prevalence of risk, injury and failure were 51 (35%), 44 (30%) and 52 (35%) patients respectively. In the patients older than 65, AKI was more common (p=0.03). In the patients with AKI compared to other patients, serum sodium (Na), Potassium (K), was higher but haemoglobin and platelet were significantly lower. During ICU admission 91 (17.5%) patients died, out of which 56 (38%) cases had AKI and 35 (9.3%) had not (p<0.001). Among dead patients, prevalence of risk, injury and failure were 16%, 30.3% and 53.5% respectively. Among the alive patients, after hospital discharge, 3 months survival were 55.1%, 54.9%, 46.8% and 68.9% in risk, injury, failure and non AKI groups respectively (p=0.002), however six months survival of the AKI patients were 54.7%, 46.3% and 24.9% in risk, injury and failure patients comparing to 69.2% in non AKI patients respectively (p=0.001). Conclusion: The study showed that inpatient mortality and short term survival of the ICU admitted ...
