Background & Objectives Cancer treatment is still one of the main challenges in the field of basic science and clinical science in medicine. Surgery is often the first option in the treatment of cancer, providing the tumor in a way that can be removed. Chemotherapy, radiation therapy, or a combination of both can be used to reduce the tumor in the pre- or post-surgical stage. Hormone therapy, stem cell and bone marrow cell transplantation, and immunotherapy are among other therapeutic approaches. Immunotherapy or the use of the immune system for treatment, after chemotherapy and radiation therapy is one of the most important complementary and effective methods for treating cancer. Immunotherapy such as chemotherapy is systematically done and used to prevent the spread of malignancies, but unlike that only attacks malignant cells and does not effect on normal cells. Cancer, immune therapy with the direct use of immune system components and makes an active immune response such as stimulating the patient's immune system cells and reintroducing these cells to the individual. Indirect stimulation and the use of immune products such as anti-cancer monoclonal antibody to remove tumor antigens is called passive immune therapy. Results The results from clinical trials confirm the design of combined therapies for cancer treatment, which include a combination of various immune therapies along with chemotherapy or the combination of several therapeutic immunotherapy approaches. Conclusion The goal of this review article is to concisely review some of the most important recent developments in cancer immunology and immunotherapy, and explain new insights into the mechanisms that underlie cancer immune evasion by which might lead to pathways for identifying novel treatments.

Background & Objectives: Soil pollution with heavy metals can decrease Fe availability in human food chain in industrial regions. This research was done to investigation the quality of tomato grown in a soil treated with iron slag and its effect on human health.Materials and Methods: This research was done in 2016 in a greenhouse experiment in Arak province with 72 pots including: applying 0, 15 and 30 t ha-1 cow manure enriched with 0 and 10% (W/W) iron sludge in a Pb polluted soil (0, 600, 800 and 1000 mg Pb kg-1 soil). At the end of experiment, fruit Fe concentration was measured and Fe daily intake for 4 to 50 years group was calculated.Results: Consumption of 80 g tomato which cultivated in soil treated with 30 t ha-1 enriched cow manure with iron slag can supply 18.4% Fe daily requirement for the children in the range 4 to 8 years. With increasing the Pb soil pollution up to 1000 mg/kg soil, only 12.1% Fe requirement was supplied in this age group.Conclusion: The results of this experiment showed that applying enriched cow manure with iron slag has affect on increasing Fe requirement from tomato consumption. However, tomato cultivation in Pb polluted soil can decrease fruit Fe concentration and thereby, decrease the human Fe intake.

Background:Memory and learning are one of the most complex brain functions and a mechanism for encoding, storing and recalling learned information. Due to the prevalence of learning disabilities, especially in older adults, the present study aimed to investigate the effect of hydroalcoholic extract of chamomile on avoidance memory levels in rats. Materials and Methods:In this experimental study, 48 adult male rats were divided into 6 groups: control, control 1 (treatment with normal saline) and control 2 (Shuttle Box) and three experimental groups receiving 200,100, and 400 mg/kg hydroalcoholic extract of chamomile by intraperitoneal injections. All of them were prescribed for 15 days. In this study, the Shuttle Box was used to measure memory and learning. The latency of entering and the time of remaining in a dark chamber of the Shuttle Box were recorded. The results were analyzed by ANOVA and Tukey tests using the SPSS-22 software. Results:The significance level of data was considered as p≤0.05. The results showed that doses of 200 and 400 mg/kg chamomile extract significantly increased the latency of entering the dark chamber and also doses of 100, 200, and 400 mg/kg chamomile extract significantly reduced the time of remaining in the dark chamber of the Shuttle Box in the remembering phase at the level of P≤0.001 compared to the control group. Conclusions: The results of this study showed that chamomile extract strengthens avoidance memory in rats. This effect is probably due to flavonoids, antioxidants and phytoestrogens.

Reactive oxygen species (ROS) result in serious damage oxidation of proteins, lipids and genomic structures. Studies have shown that production of ROS increases during intensive exercise training. The aim of present study was to investigate the effect of two type sprint and endurance exercise trainings on 8-oxoguanine DNA glycosylase (OGG1) and hydroxy-2'-deoxyguanosine (8-OHdG) levels in the brain and liver of Wistar rats. 24 adult Albino Wistar rats were randomly divided into sedentary control, sprint exercise training, and endurance exercise training groups. Rats in sprint and endurance exercise training groups ran on treadmill for 6 weeks, 6 days per week, at 80 to 100 percent of maximal oxygen consumption. OGG1 and 8-OHdG levels were measured using sandwich ELISA assay. Data analyzed using one way ANOVA at P≤0.05 level. Results showed that both of sprint and endurance exercise trainings result in significant increase in OGG1 levels in brain and liver. Sprint exercise training resulted in greater increase in brain OGG1 than endurance exercise training. However, sprint and endurance exercise training had no significant effect on 8-OHdG levels in brain and liver tissues. OGG1 content correlated negatively with 8-OHdG levels. Collectively, sprint and endurance exercise trainings prevents from genomic structure through an increase in OGG1 contents.
