Progression associated with Many studies in Ovarian Cancers Management during the last Twenty years: Never Subside, Always Rise above.
The World Health Organisation, in its 2019 progress report on HIV, viral hepatitis and STDs indicates that 257 million people are afflicted with chronic HBV infections, of which, 1 million patients lose their lives every year due to HBV related chronic liver diseases including serious complications such as liver cirrhosis and hepatocellular carcinoma. The course of HBV infection and associated liver injury depend on several host factors, genetic variability of the virus, and the host viral interplay. The challenge of medical science is the early diagnosis/identification of the potential for development of fatal complications like liver cirrhosis and HCC so that timely medical intervention can improve the chances of survival. Currently, neither the vaccination regime nor the diagnostic methods are completely effective as reflected in the high number of annual deaths. It is evident from numerous publications that microRNAs (miRNAs) are the critical regulators of gene expression and various cellular processes lilso discusses the possible use of exosomal miRNAs as biomarkers in the early detection of HCC and liver cirrhosis. © The Author(s) 2020.Background Emerging evidence closely links Enterovirus 71 (EV71) infection with the generation of reactive oxygen species (ROS). Excess ROS results in apoptosis and exacerbates inflammatory reactions. The Keap1-Nrf2 axis serves as an essential oxidant counteracting pathway. Methods The present study aimed to elucidate the role of the Keap1-Nrf2 pathway in modulating apoptosis and inflammatory reactions triggered by oxidative stress in Vero and RD cells upon EV71 infection. Results Elevated ROS production was identified in EV71 infected Vero and RD cells. The percentage of dead cells and expression of inflammation-promoting cytokines were increased in these cells. EV71 infected cells also displayed reinforced Keap1 expression and abrogated Nrf2 expression. Keap1 silencing resulted in the downstream aggregation of the Nrf2 protein and heme oxygenase-1 HO-1. selleck chemicals llc Keap1 silencing repressed ubiquitination and reinforced Nrf2 nuclear trafficking. Furthermore, silencing Keap1 expression repressed ROS production, cell death, and inflammatory reactions in EV71 infected RD and Vero cells. In contrast, silencing of both Keap1 and Nrf2 restored ROS production, cell death, and inflammatory reactions. Nrf2 and Keap1 modulated the stimulation of the Akt sensor and extrinsic as well as intrinsic cell death pathways, resulting in EV71-triggered cell death and inflammatory reactions. Conclusions EV71 infection can trigger ROS production, cell death, and inflammatory reactions by modulating the Nrf2 and Keap1 levels of infected cells. link2 © The Author(s) 2020.Background Pre-operative anemia is a common, but treatable, condition encountered by surgical patients. It has been associated with increased perioperative complications, length of stay, and blood transfusions. The aim of this project was to increase the treatment rate of pre-operative anemia to 75% of patients consented for major hepato-pancreato-biliary (HPB) surgery. Methods This was an interrupted time series study and a spread initiative from a similar project in a colorectal surgery population. link3 Interventions included an anemia screening and treatment algorithm, standardized blood work, referral to a patient blood management program, and standardized oral iron prescriptions. The primary outcome measure was the change in pre-operative anemia treatment rate and the secondary outcome measure was the post treatment increase in hemoglobin. Results A total of 208 patients were included (n = 124 pre-intervention and n = 84 post-intervention). Anemia was present in 39.9% of patients. The treatment rate of pre-operative anemia increased to 44.1% from 28.6%. The mean hemoglobin increased from 110 g/L to 119 g/L in patients who were treated (p = 0.03). There was no significant increase or decrease in blood transfusions or mean number of red cell units transfused per patient. Screening rates for pre-operative anemia increased from 41.1 to 64.3% and appropriate referrals to the patient blood management program increased from 14.3 to 67.6%. Conclusions This study demonstrates a small scale spread initiative focused on the treatment of pre-operative anemia. Although the goal to treat 75% of anemic patients was not reached, an effective referral pathway to an existing patient blood management program was developed, and a significant increase in the mean hemoglobin in anemic patients who have been treated pre-operatively was demonstrated. © The Author(s) 2020.Background Rhamnolipids are the best known microbial-derived biosurfactants, which has attracted great interest as potential ''green" alternative for synthetic surfactants. However, rhamnolipids are the major contributors to severe foam problems, which greatly inhibit the economics of industrial-scale production. In this study, a novel foam-control system was established for ex situ dealing with the massive overflowing foam. Based on the designed facility, foam reduction efficiency, rhamnolipids production by batch and repeated fed-batch fermentation were comprehensively investigated. Results An ex situ foam-control system was developed to control the massive overflowing foam and improve rhamnolipids production. It was found that the size of individual bubble in the early stage was much larger than that of late fermentation stage. The foam liquefaction efficiency decreased from 54.37% at the beginning to only 9.23% at the end of the fermentation. This difference of bubble stability directly resulted in higher kinds of defoamers, respectively. Conclusions The ex situ foam-control system presented a notable reduction efficiency, which helped greatly to easily solve the severe foaming problem without any defoamer addition. Moreover, rhamnolipids production and yield by repeated fed-batch fermentation obtained prominent improvement compared to conventional batch cultivation, which can further facilitate economical rhamnolipids production at large scales. © The Author(s) 2020.Background Biosynthesis of sabinene, a bicyclic monoterpene, has been accomplished in engineered microorganisms by introducing heterologous pathways and using renewable sugar as a carbon source. However, the efficiency and titers of this method are limited by the low host tolerance to sabinene (in both eukaryotes and prokaryotes). Results In this study, Escherichia coli BL21(DE3) was selected as the strain for adaptive laboratory evolution. The strain was evolved by serial passaging in the medium supplemented with gradually increasing concentration of sabinene, and the evolved strain XYF(DE3), which exhibited significant tolerance to sabinene, was obtained. Then, XYF(DE3) was used as the host for sabinene production and an 8.43-fold higher sabinene production was achieved compared with the parental BL21(DE3), reaching 191.76 mg/L. Whole genomes resequencing suggested the XYF(DE3) strain is a hypermutator. A comparative analysis of transcriptomes of XYF(DE3) and BL21(DE3) was carried out to reveal the mechanisanisms that are important for sabinene tolerance. In addition, for the first time, ybcK, ygiZ, and scpA were identified to be important for terpene tolerance in E. coli BL21(DE3). © The Author(s) 2020.Cancer patients in conflict settings experience significant barriers in accessing chemotherapy and radiotherapy as well as palliative care and psychosocial support. Now they face an additional possible risk of infection by SARS-CoV-2 novel coronavirus and the indirect impact of the COVID-19 pandemic on movement restrictions and their access to care. In this commentary, we highlight that despite the low COVID-19 burden in conflict settings like Gaza, COVID-19 could lead to further inequity in cancer care and poorer outcomes for Palestinians with cancer. This is due to the pre-existing shortage in cancer resources as well as the lack of context-specific guidelines to prepare for COVID-19 in war-torn settings. © the authors; licensee ecancermedicalscience.The impact of COVID-19 on healthcare in low- and middle-income countries (LMICs) is a major challenge requiring urgent measures. Cancer care in LMICs, including Ghana, is faced with inadequate numbers of skilled healthcare professionals and essential material resources which negatively impacts the quality of healthcare and wellbeing of patients. In the face of COVID-19, cancer patients are likely to be affected in three key ways access to healthcare, increased financial toxicity and increased mental health burden as a consequence of strict measures being implemented to contain the virus in Ghana, including partial lockdowns and social distancing. Some cultural beliefs regarding COVID-19 and its influence on the health and wellbeing of cancer patients have also been discussed. Measures by the government to lessen the burden on citizens and health workers are highlighted with possible recommendations for improvement in cancer care in Ghana and other LMICs during this pandemic. © the authors; licensee ecancermedicalscience.Across much of the world, cancer care has been sidelined to a variable degree by the global effort against the coronavirus pandemic. This paper discusses the impact of coronavirus infection on cancer diagnosis and treatment in two leading cancer centres in Pakistan. It also describes the effect that preparations for the expected surge in cases in Pakistan over the next few weeks have had on cancer care. There is an urgent need to evaluate the effect of delays in diagnosis and treatment on cancer stage and treatment, and to decide how to minimise these during likely future cycles of lockdown over the coming months and years. © the authors; licensee ecancermedicalscience.Aims The purpose of this research was to calculate and compare standardised incidence and mortality ratios in young adults, based on the data published by the population-based cancer registry of Metropolitan Lima. Method A secondary analysis was carried out on the data published by the population-based cancer registry of Metropolitan Lima in its last five volumes. Calculating the standardised incidence ratio, in accordance with the World Health Organization's standard population, was done using the direct method, and the annual percentage change was calculated using the Joinpoint Regression Program. Results From 1990 to 2012, 12,380 new cases of cancer in young adults between the ages of 20 and 49 were reported in Metropolitan Lima. The neoplasms with the highest standardised incidence ratio in the young adult male group were testicular cancer, brain and nervous system cancer, stomach cancer, non-Hodgkin's lymphoma and bowel cancer. The neoplasms with the highest standardised mortality ratio for this group were stomach cancer, brain and nervous system cancer, non-Hodgkin's lymphoma, tracheal cancer, bronchial and lung cancer and liver cancer. The neoplasms with the highest standardised incidence ratio in the young adult female group were breast cancer, cervical cancer, thyroid cancer, ovarian cancer and brain and nervous system cancer. The neoplasms with the highest standardised mortality ratio for this group were breast cancer, cervical cancer, stomach cancer, brain and nervous system cancer and non-Hodgkin's lymphoma. Conclusions Young adults represent a highly unique group, characterised by little diagnostic suspicion, distribution and aggressiveness of the neoplasms that occur in them. Assessing and reporting incidence and mortality ratios in this age group can contribute to decision making. © the authors; licensee ecancermedicalscience.
