Abstract

The prostate is a small gland located below the bladder and upper part of the urethra. In developed countries prostate cancer is the second common cancer (after skin cancer), and also the second leading cause of cancer death (after lung cancer) among men. The several studies have been shown prostate cancer familial aggregation. The main reason for this aggregation is inheritance included genes. The family history is an important risk factor for developing the disease. The genes AR, CYP17, SRD5A2, HSD3B1 and HSD3B2 are all intimately involved in androgen metabolism and cell proliferation in the prostate. Each shows intraspecific polymorphism and variation among racial-ethnic groups that is associated with the risk of prostate cancer. Some of genes expressed in the prostate are in association with the production of seminal fluid and also with prostate cancer. Epigenetic modifications, specifically DNA hypermethylation, are believed to play an important role in the down-regulation of genes important for protection against prostate cancer. In prostate cancer numerous molecular and genetic aberrations have been described. It is now well established that cancer cells exhibit a number of genetic defects in apoptotic pathways. In this review article, the most recent data in molecular genetic, prevention and especially gene therapy in prostate cancer are introduced.

Abstract
Background: Nowadays, the COVID-19 pandemic has become a global problem that new methods must be used to prevent it. The virus is highly contagious and is mainly transmitted through the air. Ozone is a powerful oxidant that can be used to inactivate a wide range of viruses that may be resistant to other disinfectants. The purpose of this study was to review the use and effect of ozone in inactivating indoor viruses.
Methods: To conduct this review study, the keywords such as ozone, virus and air were used to search the PubMed and Scopus databases. Articles were searched from 2010 to 2020. As a result of the search, 57 articles in this field were selected and their content and results were used in this review study. 
Results: This review study showed that ozone has been successfully used to prevent several viral diseases such as COVED-19. In addition, some viruses, such as coronaviruses, contain sulfhydryl functional groups containing cysteine and tryptophan that react better with ozone gas. The infected person's sneezing may result in the formation of 40,000 droplets in the air. The droplets can be transferred to the nearest surface up to approximately 2 meters before falling and also may remain in the air for 30 hours.
Conclusion: The use of ozone gas has many potential applications in inactivating viruses in enclosed spaces. Given the importance of virus-containing aerosols in the transmission of COVED-19, ozone can be a promising way to prevent the disease. The degree of inactivation of viruses by ozone gas depends on the gas concentration, contact time, temperature, humidity and type of virus. In general, studies in this field have shown the use of ozone gas in preventing the spread of viral diseases such as COVED-19. Necessary safety measures and precautions are also recommended in using this gas.

Application of bone cements based on ceramic and polymer in orthopedic surgeries: a review article

Abstract
For over 50 years, bone cement has been used to strengthen artificial joints like hip, knee, shoulder, and elbow joints. The main purpose of bone cement is to fill the space between the prosthesis and the bone. This absorbs the forces on the joint by creating an elastic area. Besides ensuring the long-term stability of the artificial implant, it also improves the damaged bone. Polymeric bone cement consists of a polymer matrix known as polymethyl methacrylate (PMMA) and a liquid monomer called methyl methacrylate (MMA). When these two components are mixed, a free radical polymerization reaction occurs, leading to the cement's hardening at the place of use. The properties of bone cement, such as mechanical strength, biocompatibility, and handling characteristics, can be adjusted by combining the effective polymerization parameters. However, there are some challenges, such as heat generation during polymerization.
Ceramic bone cement is a composite material of ceramic particles dispersed in a polymer matrix, including calcium phosphate and calcium sulfate. The ceramic particles provide strength and bioactivity, while the polymer matrix enhances the transport properties of the cement. This combination results in a mechanically stable, bone-conductive, and biocompatible cement. Moreover, ceramic bone cement can be engineered to release therapeutic agents, such as antibiotics or growth factors, to prevent infection and foster bone regeneration. Ceramic bone cement is a promising alternative material for bone cement in joint replacement. However, more research and development are required to optimize the properties of bone cement and overcome the challenges associated with its use. With continued advancements in biomaterials, ceramic and polymer bone cement could revolutionize the field of orthopedic surgery and improve patient outcomes. Recent research has focused on developing new bone cement with improved properties like bioactivity, antibacterial activity, and drug delivery capabilities. These developments aim to enhance the performance of bone cement and remove the current limitations in orthopedic applications. In this review study, we will focus on the types of bone cement, their mechanical, biological, and structural properties, and how to optimize them.

Abstract
Background: Today, addiction is a major problem in modern society, which affects the management of patients during anesthesia. In patients with long-term use of opioids, higher doses of opioids are needed to create analgesia and control pain during and after surgery. Also, addicted patients have more resistance to local anesthetic drugs when they are used to perform peripheral and central nerve blocks. Therefore, many drugs are added to local anesthetics to enhance their analgesic properties, one of the most common of which is narcotic compounds. Itching caused by opium may be generalized and often occurs shortly after injection. Therefore, this study aims to investigate the amount of itching caused by intrathecal injection of fentanyl in opium addicts who undergo elective orthopedic surgeries of the lower limbs with spinal anesthesia. have been taken, designed and established.
Methods: This study was a double-blind clinical trial conducted on 68 patients who were candidates for elective lower limb orthopedic surgeries under spinal anesthesia and referred to 5 Azar Hospital in Gorgan in 2023. Patients were divided into two groups using random numbers table, Intervention (a group of addicted patients who received intrathecal marcaine together with fentanyl for spinal anesthesia) and control (a group of addicted patients who received only intrathecal marcaine for spinal anesthesia). Pruritus, nausea and vomiting were measured in both groups. Data analysis was done using descriptive statistics and inferential statistical tests.
Results: In terms of age, gender, and BMI, there was no statistically significant difference between the intervention and control groups. There was no statistically significant difference in the incidence of nausea and vomiting between the two groups. The incidence of itching was zero in the bupivacaine group and 17.6% in the fentanyl and bupivacaine group, of which 3% required anti-itch medication for treatment.
Conclusion: The results of this study showed that due to the low incidence of pruritus in the group using fentanyl along with bupivacaine, its use is beneficial in people with drug addiction.
