According to the efficient therapeutic properties of P. ostreatus on leukemia cell lines, this mushroom could be introduced as a natural medicine to cure leukemic patients who suffer from the harmful side effects and enormous costs of chemotherapy.
Background Recent studies have introduced Pleurotus ostreatus (Pleurotaceae) as a herbal medicine for treating different types of cancer. This survey utilizes P. ostreatus and doxorubicin hydrochloride (DOX) alone and then with hyperthermia to investigate the erythroleukemia cell line. This study evaluates and compares the apoptotic and necrotic effects of various treatments on the KG-1 cell line. Methods The proliferation of KG-1 cells was measured by using a tetrazolium salt (MTT)-based colorimetric assay during 96 h after treatment by gradient dilutions of 100 ng/mL to 100 mg/mL of P. ostreatus methanol extract and then the minimum inhibitory concentration (MIC) was determined and was applied in additional experiments. Afterward, the cells were treated using P. ostreatus extract, DOX (6.95 mg/L), and hyperthermia (42 and 44 °C), separately and then applying hyperthermia. Finally, the ratios of apoptosis and necrosis after 24 h incubation were evaluated by using flow cytometry. Results The MIC of the extract was determined (1 mg/mL), which significantly increased the ratio of apoptosis rather than necrosis, whereas the DOX treatment primarily induced necrosis on the KG-1 cells. The anticancer effects of the mushroom extract were significantly increased when it was combined with thermotherapy, which exhibited apoptotic effects at 42 °C but induced necrosis at 44 °C. Conclusions The results suggest that P. ostreatus extract induces apoptosis on KG-1 cells and its anticancer effects are significantly increased in combination with thermotherapy. Therefore, P. ostreatus could be considered as an alternative with anticancer effect for further studies in erythroleukemia patients.
Background: Brucellosis, also called Malta fever, is a highly contagious zoonosis caused by ingestion of unpasteurized milk or undercooked meat from infected animals, or close contact with their secretions. Brucella species are small, Gram-negative, non-motile, non-spore-forming, rod-shaped (coccobacilli) bacteria. Objectives: The aim of this study is to perform an evaluation of Isfahan inhabitant attitude about brucellosis and its common herbal treatment. Patients and Methods:This evaluation was a simple random sample study, which was carried out on 162 people in the city of Isfahan, Iran, by means of questionnaires. The data was analyzed using SPSS for Windows (Version 21.0). Results: Of 162 people that were interviewed, 90 (55.6%) patients were male and the other were female. Of these, 74 (45.7%) patients were single and 88 (54.3%) were married. Forty-three (26.5%) participants lived in the city. The average age of participants was 11.51 ± 29.11 years. There is no significant relationship between age, gender, education level, residence, and people familiar with the disease brucellosis, herbal treatment for brucellosis (P > 0.05). Conclusions: Our data suggest that the demographic and socioeconomic characteristics of people in Isfahan, Iran, show no relationship with the attitude of individuals regarding brucellosis and towards common herbal treatments for the disease.
IntroductionThe COVID-19 pandemic has changed aspects of patient care in the many scheduled medical activities, restricted access to healthcare facilities, and affected the diagnosis and organisation of patients with other health problems, specifically skin cancer. Skin cancer, the uninhibited progress of atypical skin cells, happens with unrepaired DNA genetic faults that lead them to multiply and create malignant tumours. Currently, dermatologists perform skin cancer diagnosis based on their specialised experience using the results of pathological tests from the skin biopsy. Sometimes, some specialists advise sonography imaging to check the skin tissue as a non-invasive method. The outbreak has led to postponements in the treatment and diagnosis of patients with skin cancer, including diagnostic delays because of limitations of diagnostic capacities and delays in referring patients to the physician. The purpose of this review is to improve our understanding of the impact of the COVID-19 outbreak on the diagnosis of patients with skin cancer and conduct a scoping review to identify whether routine skin cancer diagnoses are affected by the persistent incidence of COVID-19.Methods and analysisThe structure of research was compiled using Population/Intervention/Comparison/Outcomes/Study Design and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. First, we will find the main keywords to capture scientific studies related to the impact of the COVID-19 pandemic on the diagnosis of skin cancer: COVID-19 and skin neoplasms. To warrant sufficient coverage and identify potential articles, we will search the combination of four electronic databases PubMed/MEDLINE, Scopus, Web of Science and EMBASE, and ProQuest from 1 January 2019 until 30 September 2022. The screening, selection and data extraction of studies will be performed by two independent authors, who will then assessed the quality of the included studies according to Newcastle–Ottawa Scale.Ethics and disseminationAs this study will be a systematic review without human participants’ involvement, no formal ethical assessment is required. Findings will be presented at conferences related to this field and will be disseminated in a peer-reviewed journal.PROSPERO registration numberCRD42022361569.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
