This study examined whether framing, exemplar presence and exemplar race in social media news posts influence rural White men's perceptions, attitudes and behavioral intentions toward clinical trial participation, and if so, how individual trust in doctors moderates the effects of these three factors. An experiment with a 2 within (framing: cognitive versus psychological barriers) × 2 within (exemplar: present versus absent) × 2 between (exemplar race: White versus Black) subjects mixed factorial design was conducted among rural White men (N = 208). Twelve social media news posts about clinical trial participation were created for the experiment.

Control over gene expression is exerted, in multiple stages of spermatogenesis, at the post-transcriptional level by RNA binding proteins (RBPs). We identify here an essential role in mammalian spermatogenesis and male fertility for 'RNA binding protein 46' (RBM46). A highly evolutionarily conserved gene, Rbm46 is also essential for fertility in both flies and fish.

Research has suggested that Instagram is detrimental to one's body image and health, as a result of its image-driven nature and the social comparisons that are commonly made between users' bodies and the bodies they see portrayed. This study was designed to provide a better understanding of the effects of thin and fat body types portrayed in Instagram posts. This was done by examining how such body type portrayals influence attention to the posts, in addition to influencing outcomes such as body dissatisfaction and appearance management behavioral intentions.

The current study was designed to examine effective message strategies that can be employed in designing mediated communication messages to improve clinical trial research participation. In the study, a total of 300 participants completed an online experiment in which they responded to five different clinical trial recruitment advertisements whose information sources varied in their credentials and race. Overall, peer-featured ads in which previous clinical trial participants communicated their prior experience in clinical trial participation, compared to expert-featured ads in which medical doctors communicated information about clinical trials, led to higher message and topic relevance, higher message credibility, more favorable attitudes toward clinical trials, and higher intentions to participate in future clinical trials.

Within the theoretical frameworks of the dual coding theory, this study examined how the implementation of infographics would influence audiences' cognitive responses to science news reporting topics of genetically modified food and bioengineering. A total of 280 participants were randomly assigned to view news articles that report genetically modified food information presented via infographics or text. Findings showed that the participants recalled more information, elaborated more message-relevant thoughts, and had more favorable attitude changes toward the genetically modified foods when science news content is presented in infographics compared with text.

Media play an important role in communicating scientific and health-related information, in turn, influencing audience risk perception. This study examined how genetically modified (GM) food news' presentation - text-only, addition of photographs, or addition of infographics - can affect risk perception and attitude towards GM foods. Further, individuals' healthy eating involvement and perceived threat to GM foods were considered as individual difference variables influencing the level of perceived relevance to the GM food news.

Cleft lip is one of the most common human birth defects. However, there remain a limited number of mouse models of cleft lip that can be leveraged to characterize the genes and mechanisms that cause this disorder. Crosstalk between epithelial and mesenchymal cells underlies formation of the face and palate, but the basic molecular events mediating this crosstalk remain poorly understood.

This research endeavors to understand how pediatricians and parents discuss - or do not discuss - firearm risks for children during well-child visits. Through individual semi-structured interviews with 16 pediatric providers and 20 parents, the research explores discursive barriers to open conversation, perspectives on anticipatory guidance, and new ideas for culturally competent messaging. The research focuses particularly on how parents' and providers' perspectives on firearm risk communication are tied to cultural norms and expectations.

This study investigated the effect of applying a customized diabetes education program through pattern management (PM), using continuous glucose monitoring system (CGMS) results, on individual self-care behaviors and self-efficacy in patients with type 2 diabetes mellitus. Patients with type 2 diabetes who had never received diabetes education, enrolled from March to September 2017, were sequentially assigned to either PM education or control groups. In the PM education group, the CGMS test was first conducted one week before diabetes education and repeated three times by PM in order to obtain data on self-care behaviors and self-efficacy.

The epithelial-specific splicing regulators Esrp1 and Esrp2 are required for mammalian development, including establishment of epidermal barrier functions. However, the mechanisms by which Esrp ablation causes defects in epithelial barriers remain undefined. We determined that the ablation of Esrp1 and Esrp2 impairs epithelial tight junction (TJ) integrity through loss of the epithelial isoform of Rho GTP exchange factor Arhgef11.

D-erythroascorbate peroxidase (EAPX1) deficiency causes glutathione deprivation, leading to the accumulation of methylglyoxal and reactive oxygen species (ROS), and especially, induction of cytochrome c peroxidase (Ccp1) in Candida albicans. Nevertheless, reciprocal effects between changes in Ccp1 activity and the antioxidative D-erythroascorbic acid- and glutathione-dependent redox status, which reflects methylglyoxal biosynthesis altering pathophysiology are unclear in eukaryotes. To elucidate the effect of CCP1 expression on EAPX1 and glutathione reductase (Glr1) activity-mediated D-erythroascorbic acid biosynthesis and redox homeostasis, the CCP1 gene was disrupted and overexpressed.

Coordination of cell proliferation, differentiation and survival is essential for normal development and maintenance of tissues in the adult organism. Growth factor receptor tyrosine kinase signaling pathways and planar cell polarity pathways are two regulators of many developmental processes. We have previously shown through analysis of mice conditionally null in the lens for the planar cell polarity gene (PCP), Dlg-1, that Dlg-1 is required for fiber differentiation.
