0 × 10-4 ng/mL to 10 ng/mL. The method was successfully applied to the analysis of corn hazelnut samples for ZEN. Graphical abstract Schematic presentation of a self-enhanced electrochemiluminescent ratiometric immunosensor based on octahedral anatase mesocrystals (OAM) supported ABEI-glutathione (GSH) and g-C3N4 functionalized helical carbon nanotubes (HCNT) for zearalenone (ZEN) determination.The World Health Organization (WHO) called the outbreak of coronavirus infectious disease-2019 (COVID-19) a "Public Health Emergency of International Concern" (PHEIC). According to the WHO, Centers for Disease Control and Prevention (CDC), and the US Food and Drug Administration (FDA), currently there are no medicines or vaccines that have been claimed to be useful in the prevention or treatment of COVID-19. Several existing antiviral drugs, previously developed or used as treatments for severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), human immunodeficiency virus (HIV), and malaria, are being investigated as COVID-19 treatments and some of them are being used in clinical trials. According to the CDC and Chinese treatment guidelines for COVID-19, chloroquine, hydroxychloroquine, lopinavir/ritonavir, and one of the investigational agents (remdesivir) are recommended in critically ill older patients. The use of other potential drugs reported in different studies may be considered if treatment with first-line drugs is ineffective. There are currently no complete data available from large randomized clinical trials (RCTs) to provide clinical guidance on the use, dosing, or duration to validate the effective role, safety profile, and adverse effects of all of the trial drugs for prophylaxis or treatment of COVID-19. Until now, it is still unclear which drug can successfully fight against the disease. Therefore, for the better safety of patients with COVID-19, further clinical trials and large randomized controlled studies are needed to validate the effective role, safety profile, and adverse effects of all the potential drugs. Such a measure requires action at the global level.With greater understanding of underlying biology and development of effective BRAF-targeted therapy and immunotherapy, along with remarkable advances in local treatment such as stereotactic radiosurgery, melanoma brain metastasis (MBM) is witnessing continually improving outcome, with 1-year overall survival rate approaching 85%. Given disease complexity and myriad treatment options, all patients with MBM should ideally be evaluated in a multidisciplinary setting to allow an individualized treatment approach based on prognostic groups, molecular classification, number and size of brain metastasis, and performance status. With improving outcome, pendulum has now swayed to focus more on effective treatment modalities with minimal neurological toxicity while maintaining quality of life. Sodium L-ascorbyl-2-phosphate Surgery is usually considered in symptomatic and large MBMs, while stereotactic radiosurgery considered in 1-4 lesions, and now also being explored for up to 15 brain metastases for improved local control. The role of whole brainuld be evaluated prospectively. Promising ongoing trials will further expand therapeutic evidence in MBM, and patients should be encouraged to participate in clinical trials.Sodium butyrate applied to Petunia hybrida seeds under a long-day photoperiod has a negative impact (reduced seedling length, decreased production of photosynthetic pigments, and accumulation of DNA damage) on early seedling development, whereas its administration under dark/light conditions (complete dark conditions for 5 days followed by exposure to long-day photoperiod for 5 days) bypasses some of the adverse effects. Genotoxic stress impairs plant development. To circumvent DNA damage, plants activate DNA repair pathways in concert with chromatin dynamics. These are essential during seed germination and seedling establishment, and may be influenced by photoperiod variations. To assess this interplay, an experimental design was developed in Petunia hybrida, a relevant horticultural crop and model species. Seeds were treated with different doses of sodium butyrate (NaB, 1 mM and 5 mM) as a stress agent applied under different light/dark conditions throughout a time period of 10 days. Phenotypic (germinationgest the involvement of chromatin modification- and DNA repair-associated pathways in response to NaB and dark/light exposure during seedling development.The purpose of this study is to explore existing research on determinants of cervical cancer screening among immigrants and refugees in the U.S. A scoping review was conducted on 77 studies targeting immigrant and/or refugee women in the U.S., investigating factors related to cervical cancer screening. Sixty-three percent of studies were conducted in the past ten years, and included 122,345 women. Studies predominately explored knowledge, beliefs and barriers related to cervical cancer and screening. Common beliefs included fear of cancer, treatment and death. Participants perceived pap smears to be associated with embarrassment, pain and fear. Barriers to screening were reported in three categories psychosocial (shame and embarrassment), communication (inability to speak in English), and barriers related to access (lack of insurance or primary care provider). Study findings indicate research focused at the individual-level and future research should focus on exploring multilevel influences on cancer screening uptake.The capacity of cells to modify their phenotypes from epithelial to mesenchymal (epithelial-to-mesenchymal transition or EMT) and vice versa provides them with a dynamic plasticity essential for human life, from embryogenesis to wound healing. Current knowledge about carcinogenetic mechanisms leaves little doubts on the pivotal participation of these interchangeable processes in cancer development, and their influence has been quite clearly established in the progression of cutaneous squamous cell carcinoma. A complex and ordered interplay of signals induces the shift between both phenotypes, providing cells with the most suitable state at every moment to face the next step in tumor invasion and dissemination. Some stimulatory triggers have opposite effects according to the biological context and in many cases exert collateral functions. This scenario makes finding an ideal therapeutic target difficult but provides the opportunity to intervene simultaneously at many different levels with small actions such as targeting the tumor environment.
