The aim of the present study was to assess the expression of the Ikaros transcription factor (IKZF1) in lung adenocarcinoma and investigate whether expression levels of Ikaros are correlated with lung adenocarcinoma progression.

We conducted a retrospective study of 325 cases of resected stage I pulmonary adenocarcinoma, in which histological subtyping was performed according to the 2015 World Health Organization classification. We performed immunohistochemical examinations to assess expression of Ikaros in pulmonary adenocarcinomas and evaluated the correlation between Ikaros expression and cancer progression.

Immunohistochemical staining was heterogeneous, with the majority of well-differentiated and moderately differentiated lung adenocarcinomas being weakly positive and the majority of the poorly differentiated lung adenocarcinomas exhibiting strong positive staining. Higher expression of Ikaros was associated with tumor recurrence or metastasis.

Ikaros is heterogeneously expressed in different subtypes of lung adenocarcinoma; higher expression of Ikaros was found to be associated with cancer progression.

This disease can potentially be initiated by asexual sporangiospores via "green bridges", sexually derived oospores from seed or soil, or dormant mycelium. However, the relative importance of the various types of primary inoculum is not well known. The ability of P. effusa sporangiospores to withstand abiotic stress, such as desiccation, and remain viable during short- and long-distance dispersal and the ability of oospores to germinate and infect seedlings remain unclear. Thus, the primary objectives of this research were to evaluate the impact of desiccation on sporangiospore survival and infection efficiency and examine occurrence, production, and germination of oospores. Results indicate that desiccation significantly reduces sporangiospore viability as well as infection potential. Leaf wetness duration of 4 h was needed for disease establishment by spinach downy mildew sporangiospores. Oospores were observed in leaves of numerous commercial spinach cultivars grown in California in 2018 and Arizona in 2019. Frequency of occurrence varied between the two states-years. The presence of opposite mating types in spinach production areas in the United States was demonstrated by pairing isolates in controlled crosses and producing oospores on detached leaves as well as intact plants. Information from the study of variables that affect sporangiospore viability and oospore production will help in improving our understanding of the epidemiology of this important pathogen, which has implications for management of spinach downy mildew.We revisit the hypothesis that there is life in the Venusian clouds to propose a life cycle that resolves the conundrum of how life can persist aloft for hundreds of millions to billions of years. Most discussions of an aerial biosphere in the Venus atmosphere temperate layers never address whether the life-small microbial-type particles-is free floating or confined to the liquid environment inside cloud droplets. We argue that life must reside inside liquid droplets such that it will be protected from a fatal net loss of liquid to the atmosphere, an unavoidable problem for any free-floating microbial life forms. However, the droplet habitat poses a lifetime limitation Droplets inexorably grow (over a few months) to large enough sizes that are forced by gravity to settle downward to hotter, uninhabitable layers of the Venusian atmosphere. (Droplet fragmentation-which would reduce particle size-does not occur in Venusian atmosphere conditions.) We propose for the first time that the only way life can survive indefinitely is with a life cycle that involves microbial life drying out as liquid droplets evaporate during settling, with the small desiccated "spores" halting at, and partially populating, the Venus atmosphere stagnant lower haze layer (33-48 km altitude). We, thus, call the Venusian lower haze layer a "depot" for desiccated microbial life. The spores eventually return to the cloud layer by upward diffusion caused by mixing induced by gravity waves, act as cloud condensation nuclei, and rehydrate for a continued life cycle. We also review the challenges for life in the extremely harsh conditions of the Venusian atmosphere, refuting the notion that the "habitable" cloud layer has an analogy in any terrestrial environment.In 2014, government officials in the City of Flint, Michigan switched the municipal water source from the Detroit Water System (water source Lake Huron) to the Flint River. During this time, an estimated 102,000 Flint residents were potentially exposed to multiple chemical (e.g., lead) and biological threats (e.g., Legionella). After the switch to water sourced from the Flint River, Flint residents consistently reported concerns over water quality while also experiencing rashes, hair loss, and other health problems, including anxiety and depression. SCR7 cost This study 1) reports on the Flint Water Crisis and its subsequent impact on residents' stress, coping, resilience and trust and 2) describes a process methodology that trained, hired and deployed Flint residents as members of a multidisciplinary research team. A random sample of 320 Flint residents underwent household-based interviews to assess their health and mental health needs. Concomitantly, household water samples were obtained and residents were connected to known resources based on interview responses relative to need. This study found that declines in health and mental health status were correlated with increased stressors (i.e., fatigue, financial concern, anxiety), coping and less resilience or the capacity to recover. Perceived trust in government officials was significantly lower after the water crisis. While the water crisis generated numerous stressors, the event also galvanized community competence to engage in solution-focused coping and other adaptive capacities. By assessing and building upon Flint residents' resilience, community resource specialists, identified and subsequently strengthened city residents' ability to survive devastating challenges.Black girls in the U.S. experience high levels of discrimination and adversity. Resilience is a term used within social work, psychology, and health professions to indicate positive adaptation to adversity, trauma, or stress. This article examines traditional and alternative models of resilience through analyses of quantitative and qualitative data from an evaluation of a year-long empowerment program for 33 Black girls (mean age = 14.97 years). Based on critical consciousness theory and Black feminism, this program was designed to empower participants through critical reflection and development of positive gendered racial identity. Quantitative analyses found no change over time in traditional measures of individual resilience. However, alternative measures of collective resilience show positive change. Specifically, quantitative analyses reveal that participants developed increased awareness of structural inequalities faced by Black girls/women and decreased adherence to neoliberal ideologies of personal responsibility and individual striving. Additionally, qualitative analyses show that participants critically reflected on their experiences of oppression, developed mutual support and positive gendered racial identity, and engaged in collective action. These findings demonstrate positive effects of empowerment-based programing, challenge the utility of traditional, individually-focused models of resilience, and reframe Black girls' resistance to injustice as an alternative, collective form of resilience.Although rural youth experience marked inequities in adolescent pregnancy, there is little guidance for implementing evidence-based programs (EBPs) in rural settings. link2 When implementation occurs in rural communities, it frequently focuses on deficits, rather than strengths or capacity for growth. Using the consolidated framework for implementation research (CFIR), we describe a resiliency-focused implementation of two middle school EBPs in rural Midwestern communities, including the intervention, outer and inner settings, individuals, implementation processes and preliminary outcomes. Data included program staff interviews, feedback from local partners, community meetings notes, and participant surveys. Using the CFIR, we describe the engagement of rural communities themselves in a resilience-based implementation of adolescent pregnancy prevention EPBs. Communities self-described as rural, traditional and religious. They identified adolescent pregnancy, substance use, and academic success as priorities. To address infrastructure needs and build on local strengths, funds were used to hire local partners to implement the program. As small communities, stakeholders were closely networked and wanted to address local needs. Local partners selected the EBP based upon community values and priorities. Champions, including local partner organizations and schools were locally based and were well connected. Intensive training of local staff and piloting with adaptation assured fidelity and sustainability, while increasing community implementation skills and comfort. In Clinton County, enrollment was 1946 with students receiving the program in 6th, 7th, and/or 8th grades. In Southern Indiana, 7275 students received the program once in either 6th, 7th, or 8th. We conclude that the CFIR can facilitate the implementation of a community resilience-focused adolescent pregnancy prevention intervention in rural communities.Transgender individuals face severe stigma-driven health inequities structurally, institutionally, and interpersonally, yielding poor individual-level outcomes. Gender affirmation, or being recognized based on one's gender identity, expression, and/or role, may be considered a manifestation of resilience. To provide intervention and policy guidelines, we examined latent constructs representative of gender affirmation (legal documentation changes, transition-related medical procedures, familial support) and discrimination (unequal treatment, harassment, and attacks), and tested their impact on mental, physical, and behavioral health outcomes among 17,188 binary-identified transgender participants in the 2015 US Transgender Survey. Confirmatory factor analyses revealed high standardized factor loadings for both latent variables, on which we regressed outcomes using structural equation modeling. Fit indices suggested good model fit. Affirmation was associated with lower odds of suicidal ideation and psychological distress, and higher odds of substance use, and past-year healthcare use and HIV-testing. Discrimination was associated with higher odds of suicidal ideation, psychological distress, substance use, and past-year HIV-testing. Affirmation and discrimination interaction analyses showed lower odds of past-year suicidal ideation, with affirmation having a significant moderating protective effect against discrimination. Gender affirmation is paramount in upholding transgender health. Clarification of affirmation procedures, and increases in its accessibility, equitably across racial/ethnic groups, should become a priority, from policy to the family unit. link3 The impact of discrimination demands continued advocacy via education and policy.
