Purpose: Low-dose computed tomography (LDCT) has been reported as an effective screening method for lung cancer in high-risk populations. We aimed to examine willingness to be screened among Korean males using LDCT and to determine factors associated with lung cancer screening intentions (LCS) based on the Health Belief Model (HBM). Materials and Methods: Data were obtained from the 2015 Korean National Cancer Screening Survey, a cross-sectional survey that utilized nationally representative random sampling...

Pluripotent stem cells (PSCs) deficient for microRNAs (miRNAs), such as Dgcr8(-/-) or Dicer(-/-) embryonic stem cells (ESCs), contain no mature miRNA and cannot differentiate into somatic cells. How miRNA deficiency causes differentiation defects remains poorly understood. Here, we report that miR-302 is sufficient to enable neural differentiation of differentiation-incompetent Dgcr8(-/-) ESCs. Our data showed that miR-302 directly suppresses the tumor suppressor p53, which is modestly upregulated in Dgcr8(-/-) ESCs and serves as a barrier restricting neural differentiation...

BACKGROUND: PrEP stigma (i.e., negative attitudes toward PrEP users) has been widely documented and is considered a significant barrier to implementation. However, few studies have examined PrEP stigma using implicit measures designed to reduce demand characteristics in responding. This study examined implicit PrEP- and HIV-related stigma among gay and bisexual men using geospatial social networking applications (i.e., "hookup apps"). METHODS: Participants were presented with four simulated online profiles (pre-tested for comparability) paired with each of the following characteristics: HIV-negative, HIV-positive, on PrEP, or Substance User...

PURPOSE: Watertight closure of perforating corneoscleral lacerations is necessary to prevent epithelial ingrowth, infection, and potential loss of the eye. Complex lacerations can be difficult to treat, and repair with sutures alone is often inadequate. In this study, we evaluated a potentially sutureless technology for sealing complex corneal and scleral lacerations that bonds the amniotic membrane (AM) to the wound using only green light and rose bengal dye. METHODS: The AM was impregnated with rose bengal and then sealed over lacerations using green light to bond the AM to the deepithelialized corneal surface...

Genomic medicine has greatly matured in terms of its technical capabilities, but the diffusion of genomic innovations worldwide faces significant barriers beyond mere access to technology. New global development strategies are sorely needed for biotechnologies such as genomics and their applications toward precision medicine without borders. Moreover, diffusion of genomic medicine globally cannot adhere to a "one-size-fits-all-countries" development strategy, in the same way that drug treatments should be customized...

High-income countries are grappling with the challenge of caring for aging populations, many of whose members have chronic illnesses and declining capacity to manage activities of daily living. The 2017 Commonwealth Fund International Health Policy Survey of Older Adults in eleven countries showed that US seniors were sicker than their counterparts in other countries and, despite universal coverage under Medicare, faced more financial barriers to health care. The survey's findings also highlight economic hardship and mental health problems that may affect older adults' health, use of care, and outcomes...

Wildlife have proven valuable to our understanding of the potential effects of endocrine-disrupting chemicals (EDCs) on human health by contributing considerably to our understanding of the mechanisms and consequences of EDC exposure. But the threats EDCs present to populations of wildlife species themselves are significant, particularly for endangered species whose existence is vulnerable to any reproductive perturbation. However, few studies address the threats EDCs pose to endangered species owing to challenges associated with their study...

Plasmon-induced interfacial charge separation (PICS) is one of the key processes responsible for the improved conversion efficiencies of energy-harvesting devices that incorporate metal nanostructures. In this letter, we reveal a mechanism of PICS by visualizing (with nanometer-scale resolution) and characterizing plasmon-exciton coupling between p-type poly(pyrrole) (PPy) nanowires (NWs) and Ag nanoparticles (NPs) using light-irradiated Kelvin probe force microscopy (KPFM). Under blue-light irradiation, the Ag NPs are expected to donate electrons to the PPy NWs via a hot electron injection process...

Hispanic farmworkers experience hazardous work conditions, language barriers, poverty, and limited healthcare access that increase their risk for health problems. We sought to characterize occupational and lifestyle stressors in farmworker couples and to examine the impact of seasonal work demand and gender on health outcomes. We administered surveys to 31 couples (N = 62) in May (low work demand) and September (high work demand) of 2012. Measures included acculturation, perceived stress, depressive symptoms, quality of life, decision latitude, support (supervisor, co-worker), and work-family conflict...

Compared to their rural non-farming peers, farmers are less likely to access preventive healthcare services; however, the reasons for this disparity are poorly understood. We conducted semi-structured interviews with a total of 30 farm household members in central New York. Interview topics included farming identity, perceptions of one's health, past experiences with acute and preventive healthcare, and attitudes toward seeking healthcare services. Grounded Theory analysis of the interview transcripts revealed that (1) utilizing healthcare services is felt to be in conflict with the farming identity, (2) the need to conserve time and money for farm applications poses a barrier to healthcare utilization, (3) farmers decide to seek healthcare when they believe it is necessary to ensure survival of the farm, and (4) the decision to seek healthcare is most strongly driven by the presence of intolerable symptoms, prompting from others, and the perception that treatment will yield clear benefits...

REVIEW
Anita Boratkó, Csilla Csortos
Transforming growth factor (TGF)-β inhibited membrane associated protein, TIMAP, is the member of the myosin phosphatase targeting protein (MYPT) family of protein phosphatase 1 (PP1) regulatory subunits. The N-terminal part of TIMAP has a typical MYPT family structure with a sequence element called MyPhone (myosin phosphatase N-terminal element), a putative bipartite nuclear localization signal, a PP1 catalytic subunit binding motif, and five ankyrin repeats. The C-terminal half of TIMAP is intrinsically disordered, but ends with a functional CAAX box for lipid modification which allows localization of TIMAP at the plasma membrane...

The process for undertaking exposure assessments varies dependent on its purpose. But for exposure assessments to be relevant and accurate, they are reliant on access to reliable information on key exposure determinants. Acquiring such information is seldom straightforward and can take significant time and resources. This articles examines how the application of tiered and targeted approaches to information acquisition, within the context of European human health risk assessments, can not only lead to improvements in the efficiency and effectiveness of the process but also in the confidence of stakeholders in its outputs...

Genomic tests are the fastest growing sector in medicine and medical science, yet there remains a dearth of research on access to pharmacogenomic tests and medications. The objective of this study is to explore providers' and patients' experiences and views on test access as well as strategies used for gaining access. We interviewed clinicians who prescribed medications that should be guided by pharmacogenomic testing and patients who received those prescriptions. We organized the themes into the four dimensions suggested by the World Health Organization framework on access to medications and health technologies...

Cytosine methylation regulates essential genome functions across eukaryotes, but the fundamental question of whether nucleosomal or naked DNA is the preferred substrate of plant and animal methyltransferases remains unresolved. Here, we show that genetic inactivation of a single DDM1/Lsh family nucleosome remodeler biases methylation toward inter-nucleosomal linker DNA in Arabidopsis thaliana and mouse. We find that DDM1 enables methylation of DNA bound to the nucleosome, suggesting that nucleosome-free DNA is the preferred substrate of eukaryotic methyltransferases in vivo...

Current methods for examining antibody trafficking are either non-quantitative such as immunocytochemistry or require antibody labeling with tracers. We have developed a multiplexed quantitative method for antibody 'tracking' in endosomal compartments of brain endothelial cells. Rat brain endothelial cells were co-incubated with blood-brain barrier (BBB)-crossing FC5, monovalent FC5Fc or bivalent FC5Fc fusion antibodies and control antibodies. Endosomes were separated using sucrose-density gradient ultracentrifugation and analyzed using multiplexed mass spectrometry to simultaneously quantify endosomal markers, receptor-mediated transcytosis (RMT) receptors and the co-incubated antibodies in each fraction...

Michael Milano
Despite some progress, a significant disparity still exists in oral healthcare between individuals with intellectual or developmental disabilities and the general population. Barriers generated by finances, a lack of appropriately trained dental providers, and the patients themselves combine to create significant challenges to providing dental care. However, strategies exist that can help to decrease the magnitude of these hurdles so this disparity can be minimized.
