The multi-country outbreak of monkeypox virus (MPXV) infection, while the coronavirus disease 2019 pandemic is still an ongoing issue, has caused a new challenge.The re-emergence of MPXV and the rising incidence in non-endemic countries is turning into an upcoming threat to global health. Hence, rapid identification of the virus with appropriate methodology with the lowest false results plays a critical role in estimating the global extent of the crisis and providing preventive measures. This review summarised the main applicable strategies for primary detection and confirmation of MPXV and highlighted available data in biosafety, requirements, standard operating procedures, specimen collection, transportation and storage of clinical samples, and waste disposal of the viral agent. Also, various assays including molecular techniques, immunoassays, histopathological methods, electron microscopy, genomic sequencing, and cell culture have been illustrated. Moreover, we reflected on current knowledge of the advantages and disadvantages of each approach.

Among the DNA tumor viruses Epstein-Barr virus (EBV) and Kaposi sarcoma herpesvirus (KSHV), account for a considerable percentage of virus-associated cancers. Deregulation of transcription factors signaling pathways is one of the most significant oncogenic characteristics of EBV and KSHV. NF-κB is a transcription factor that play a remarkable role in oncogenesis because of its function as a master regulator of a spectrum of genes involved in physiological and pathophysiological process. Constitutive activation of NF-κB is a frequent and well-described event in many human malignancies. Compelling evidence represent EBV and KSHV are capable of targeting different components of NF-κB cascade. Here, we summarized recent findings to clarify the precise relationship between dysregulation of NF-κB and EBV and KSHV-related malignancies. This essay also emphasizes on contribution of various viral products in developing cancer through alteration of NF-κB signaling pathway.

Background Blood group antigens are one of the most important antigens in humans that have an impact on susceptibility to disease and may be used as a prognosis factor in different diseases such as covid-19. Objectives Study aimed to investigate the relationship between ABO blood groups and Rhesus antigen and susceptibility to COVID-19. Methods The clinical data of 398 subjects were used in the investigation collected from 148 cases vs. 250 controls. This information was obtained from Shahid Sadoughi Hospital of Yazd (IRAN) University. blood groups and outcomes was assessed using statistical tests for four populations: COV + vs. COV− and COV +/deceased vs. COV +/live. Results Out of a total of 148 COVID19 patients, 80 (54/1%) were male, 68 (45/9%) were female. Among these patients 33 (22/6%) had type A+, 44 (30/1%) had type B+, 13 (8/9%) had type AB+ and 36 (24/7%) had type O+. On the other hand, out of a 148 patients, 126 (86/3%) had positive blood types and 20 (13/7%) had negative blood types. As a result, no significant difference was found in the relationship between ABO blood groups and RH type and susceptibility to COVID-19 (p-value= 0.392 and p-value=0.847, respectively). Other data showed a significant difference between patients group with other parameters such as age (p-value<0.001) and gender (p-value<0.001). Conclusion Although in this study there was no association between blood type and RH type with COVID-19, findings about association between age and gender can confirm the results of previous studies.

Breast cancer is the most common invasive cancer and the second leading cause of cancer death in females after lung cancer (Bray et al., 2018). Only in 2018, 2,088,849 and 626,679 new cancer cases and related death, respectively, occurred in worldwide (Bray et al., 2018). Histologically, most of breast cancer cases start from milk ducts and called ductal carcinoma. The second most frequent type of breast cancer, lobular carcinoma, begins in the milk-producing glands of the breast that is histologic forms of this malignancy (Li et al., 2005;Sharma et al., 2010). Less-common other types of breast cancer include tubular, mucinous, comedo, and medullary type (Li et al., 2005). Tumor grades include types I, II and III, which are used to describe the rate of growth and
