Abstract
Introdution:. Anaplastic thyroid carcinoma (ATC) is a type of thyroid gland malignancy that originates from the anaplastic cells of this gland. This kind of malignancy is highly invasive and patients have a poor response to treatment. In this study, the effect of curcumin on apoptosis and p53 and PARP genes expression of the human anaplastic thyroid carcinoma cell line (SW-1736) examined. Curcumin is a major active ingredient in the rhizome of a Curcuma longa that has anti-oxidant, anti-inflammatory and pro-apoptosis effects.
Methods: The experimental study was carried out in October, 2016 at the Cellular and Developmental Research Center of Islamic Azad University, Shahrekord Branch.SW-1736 cells with different concentrations of curcumin (2.5, 5, 7.5 and 10 μM) to examine apoptosis and 2.5, 5 and 10 μM concentrations to examine the expression of genes P53 and PARP were incubated for 24, 48 and 72 hours. Then, apoptosis was analyzed by flow- cytometry using an Annexin V-FITC/PI kit and the expression of p53 and PARP genes were analyzed by Real Time PCR.
Results: The results of this study indicated that with increasing concentration of curcumin in dose and time dependent manner, induction of apoptosis in this cell line increased. Also, treatment with curcumin increased the expression of p53 and PARP genes in some experimental groups compared to the control group. (P=.032)
Conclusion: Curcumin has an inhibitory effect on the growth, proliferation and invasion of anaplastic thyroid cancer cells through induction of genes involved in apoptosis process. Therefore, it seems that there is a good research field for the use of Curcuma longa in the control and treatment of human anaplastic thyroid carcinoma.

Abstract
Introduction: We are currently faced with a global epidemic of a new coronavirus (SARS-CoV-2) that It affects not only thousands of people in China, but all over the world. The rapid increase in cases appears to be related to the active genome of the virus, which may affect its pathogenesis. An understanding of the novel coronavirus genomic organization will help us in understanding their origins and likely course of future evolution and identify novel cost-effective treatment.

Abstract
Introduction: With the increasing severity of the COVID-19 epidemic, wearing a mask was recommended. This recommendation seems to have created concern among the public. Wearing a mask generally reduces the risk of virus and therefore potentially saves lives. In healthy populations, wearing a mask does not appear to cause any harmful physiological changes, and the potentially life-saving benefits of wearing face masks seem to outweigh the discomforts.

Abstract
Introduction: Despite advances in the recognition of new risk factors, prevention, diagnosis and treatment, cancer is still remains as a global health problem. Several numbers of studies have recently provided evidence that because of having pro apoptotic effects, biotoxins such as bacterial toxins, could be used as potential antitumor agents. Staphylococcus aureus, as a major human pathogen, has various toxins, such as enterotoxin superfamily that causes apoptosis during infection. Therefore, it seems that there is a good research field for the use of this toxin in the control and treatment of malignancies.

Abstract
Introduction: Predisposition to cerebral venous thrombosis (CVT) also has a genetic basis and inherited thrombophilias constitute 22.4 % of the CVT cases. CVT with a varied clinical presentation and pathogenesis is one of the important causes of stroke which is not very common. Inherited thrombophilias with concomitant acquired risk factors like pregnancy may increase the risk of CVT manifold. Identification of a number of genetic variants increasing susceptibility to CVT and related traits opened up opportunity, to screening of women at high risk of developing obstetric CVT.

Abstract
Introduction: Hydatidiform mole is an abnormal pregnancy characterized by hyper-proliferation of trophoblastic cells (both cytotrophoblast and syncytiotrophoblast). If the proliferation phenomenon not well controlled, e.g. due to poor medical health care system, mole can become invasive and lead to gestational choriocarcinomas. Gestational choriocarcinoma by strong metastatic potentiality, as one of the most aggressive, malignant form of gestational trophoblastic disease, could be spread through directly vascular and the middle layer of the uterine wall (Myometrium) and would involve distant sites such as the lungs, spleen, intestines, kidney, and liver. When a hydatidiform mole occurs once, it is known as sporadic hydatidiform mole; if it happens again, the condition is known as recurrent hydatidiform mole. In recurrent form, the gestational choriocarcinoma occurrence risk increased up to a 100-fold. Therefore, early onset identify of susceptible women to recurrent molar pregnancy is clinical importance because of the increased risk of developing neoplasia. Due to the role of maternal homozygous and compound heterozygous recessive gene, mutations have been reported in hydatidiform mole occurrence, women screening can be improved by molecular genotyping methods.

Abstract
Introduction: Prostate cancer is one of the most common cancers among men, with an increasing incidence and mortality rate. In the present study, cytotoxic and pro-apoptotic effects of spirulina platensis extract on PC-3 prostate adenocarcinoma cell line were investigated.
Methods: In the present experimental study, the PC-3 prostatic cancer cells were treated in four experimental with 400, 200, 100 and 50 μg / ml extract of spirulina and incubated at 24 and 48 hours. Cytotoxicity was analyzed by MTS kit (3-(4, 5-Dimethylthiazol-2-yl)-5-(3-Carboxymethoxyphenyl)-2-(4-Sulfophenyl)-2H-Tetrazolium, Inner Salt) and apoptosis was analyzed by flow- cytometry using an Annexin V-FITC/PI kit according to the manufacturer protocol in both times. Statistical analysis was accomplished by ANOVA and Duncan tests using FlowJo and SPSS 16 software.
Results: In the experimental groups treated with extract of spirulina, the viability of the cells showed a decrease compared to control group, while this decrease was more noticeable in the experimental group of 100 μg / ml at both incubation times (<0.0071).Increased incidence of apoptosis was significantly higher in the experimental groups than the control group. However, this increase was significantly higher than the control group at concentrations of 200 μg / ml in 24h incubation time (Ƥ < 0.0331) and 100 μg / ml of 48h incubation time (Ƥ < 0.0502).
Conclusion: Extract of Spirulina at specific concentrations reduced cell growth and induced apoptosis in PC-3 prostatic cancer cells. Evidence suggests that spirulina can be used as an anticancer drug for the treatment of prostate cancer.

Abstract
Introduction: The importance of genetically modified microorganisms, including probiotics, now widely have considered as attractive vehicles for mucosal delivery of therapeutic molecules. Previous studies have indicated that mucosal administration of these molecules can effectively trigger humoral along with cellular immune responses. Therefore, development of induction of mucosal immune responses, utilizing of recombinant probiotics-based vaccines, as live delivery vectors with no side effects in humans, may contribute to effectiveness of control strategies against infection agents.
