Abstract
Background: In the present study, we hypothesized that conditioned medium (CM) derived from mesenchymal stem cells attenuates the brain oxidative stress in sepsis induced by the cecal ligation and puncture (CLP) model.
Methods: This study was performed in the Department of Physiology at Tehran University of Medical Sciences from August 2018 to April 2019. Conditioned medium was collected from mesenchymal stem cells isolated from rat's adipose tissues at the second culture passage. Male Wistar rats weighting (220-250 g) were randomly divided into three experimental groups (n=8 each): Sham, Sepsis and CM. Sepsis was induced by cecal ligation and puncture model in the Sepsis and CM groups. Animals in the CM group received the conditioned medium from 5×105 mesenchymal stem cells (2 h after sepsis induction, i. p., 3-5 mL). The systolic blood pressure and O2 saturation were measured 24 h after the treatment. The plasma and brain tissue samples were taken for inflammatory and oxidative stress assessment, respectively.
Results: Septic rats showed a significantly lower systolic blood pressure and O2 saturation level. They also had a significant increase in the plasma inflammatory indices (tumor necrosis factor-alpha [TNF-α], interleukin-6 [IL-6]) and brain malondialdehyde (MDA) content as well as a significant reduction in the brain superoxide dismutase (SOD) activity compared to the Sham group. The CM group had significantly higher systolic blood pressure and O2 saturation level compared to the septic rats. The animals in the CM group showed a significant attenuation in the plasma inflammatory indices (TNF-α and IL-6) and brain MDA content while having a significantly higher brain SOD activity compared to the Sepsis group.
Conclusion: Our findings showed that conditioned medium derived from mesenchymal stem cells has protective effects in preventing the inflammatory and oxidative stress status and may be suggested as a promising treatment in patients suffering from sepsis and septic shock.

Abstract
According to the official statistics of the World Health Organization (WHO), cervical cancer is one of the most common cancers among women after breast, colorectal, and lung cancers. The US Centers for Disease Control and Prevention (CDC) says all women have the chance to get the disease, and women over the age of 30 are more likely to get it. However, this cancer is a types of cancer that can be prevented through vaccination. This study aimed to investigate the role of vaccines in the prevention of cervical cancer. In this review study, articles published between 2016-2022 from PubMed, SID, Cochrane Library, Science Direct, and Google Scholar databases were examined. Keywords Papilloma vaccine and cervical cancer in Persian sources and HPV vaccine and Cervical Cancer in English sources were used. The subject search was also performed using MeSH medical subject headings and through the Pubmed database. Vaccination against human papillomavirus is the most cost-effective public health measure against cervical cancer. In many developed and developing countries, serious programs are underway for HPV vaccination and screening for cervical cancer. In most countries, HPV vaccination has been added to their mandatory immunization programs, effectively reducing the incidence of cervical infections and cancers. In countries where vaccination is not complete, health education and screening programs such as PAP smears every 2 years for all women and every year for those with high cancer risk or abnormal smears, have been consolidated. HPV vaccination is highly effective and has been added to immunization programs in many countries. Nowadays, three types of vaccines have been presented, of which the 9-valent Gardasil vaccine is more effective than the other two types, but in terms of cost-effectiveness, the 4-valent Gardasil vaccine is more suggested. Due to the high prevalence of cervical cancer in Iran, it is suggested that the HPV vaccine be used, screening tests be optimized and performed on a regular basis, and ways to prevent cervical cancer be taught.
