Xiaoxia Jianhua Yang Cheng, Yubo Juan Gao Ding, Xinli Ni
In adult stroke models, the neuroprotective protein, Iduna, inhibits poly (ADP-ribose) polymerase-1 (PARP-1)-dependent cell death by decreasing apoptosis-inducing factor (AIF) nuclear translocation. Because the PARP1-dependent pathway and Iduna, which promotes AIF degradation, contribute to hypoxic-ischemic (HI) brain damage in the immature brain, we examined the relationship between Iduna expression and AIF nuclear translocation in the cerebral cortex of postnatal day 7 rats after HI. Ninety rats were divided into three groups: sham, 1-h hypoxia and 2-h hypoxia...

BACKGROUND: The capacity for emotion recognition and understanding is crucial for daily social functioning. We examined to what extent this capacity is impaired in young children with a Language Impairment (LI). In typical development, children learn to recognize emotions in faces and situations through social experiences and social learning. Children with LI have less access to these experiences and are therefore expected to fall behind their peers without LI. METHOD: In this study, 89 preschool children with LI and 202 children without LI (mean age 3 years and 10 months in both groups) were tested on three indices for facial emotion recognition (discrimination, identification, and attribution in emotion evoking situations)...

Big data is becoming increasingly more prevalent and it affects the way nurses learn, practice, conduct research and develop policy. The discipline of nursing needs to maximize the benefits of big data to advance the vision of promoting human health and wellbeing. However, current practicing nurses, educators and nurse scientists often lack the required skills and competencies necessary for meaningful use of big data. Some of the key skills for further development include the ability to mine narrative and structured data for new care or outcome patterns, effective data visualization techniques, and further integration of nursing sensitive data into artificial intelligence systems for better clinical decision support...

Fear learning is a fundamental behavioral process that requires dopamine (DA) release. Experience-dependent synaptic plasticity occurs on DA neurons while an organism is engaged in aversive experiences. However, whether synaptic plasticity onto DA neurons is causally involved in aversion learning is unknown. Here, we show that a stress priming procedure enhances fear learning by engaging VTA synaptic plasticity. Moreover, we took advantage of the ability of the ATPase Thorase to regulate the internalization of AMPA receptors (AMPARs) in order to selectively manipulate glutamatergic synaptic plasticity on DA neurons...

In this investigation, the students' goal was to isolate and characterize Agrobacterium strains from soil. Following selection and enrichment on 1A-t medium, putative Agrobacterium isolates were characterized by Gram stain reaction and biochemical tests. Isolates were further evaluated using polymerase chain reaction (PCR) with different primer sets designed to amplify specific regions of bacterial deoxyribonucleic acid (DNA). Primer sets included AGRH to identify isolates that were members of the Rhizobiaceae, BIOVAR1 primers to identify members of Agrobacterium biovar group I, and a third set, VIRG, to determine presence of virG (only present in pathogenic Agrobacterium strains)...

Noah H Green, Douglas G McMahon, Cynthia Brame
A common tool that animals use to navigate in a constant direction is known as "time compensated sun compass orientation." This is a process by which animals use the position of the sun along with information from their internal circadian clocks to determine and maintain a directional heading. Many circadian scientists and educators use this process as an example of how the internal circadian clock can directly influence animal behavior. However, many students have difficulty grasping this biological process due to its multivariable nature...

Although a majority of under-represented minority (URM) students begin their postsecondary education at community colleges, little is known about barriers to success and retention for transfer-bound science students. This study focuses on some of the barriers that affect these students' ability to study adequately for a community college "gateway" course. It tests whether instructors' expectations of study time were realistic for community college students and whether students reported facing external barriers, such as job and family responsibilities, or internal barriers to studying, such as lack of motivational, cognitive, and metacognitive abilities, all of which have been shown to impact academic success and retention...

The goal of our study was to track changes in student understanding of the central dogma of molecular biology before and after taking a genetics course. Concept maps require the ability to synthesize new information into existing knowledge frameworks, and so the hypothesis guiding this study was that student performance on concept maps reveals specific central dogma misconceptions gained, lost, and retained by students. Students in a genetics course completed pre- and posttest concept mapping tasks using terms related to the central dogma...

Cool-associated tyrosine phosphorylated protein-1 (Cat-1) is a signaling scaffold, as well as an ADP-ribosylation factor-GTPase-activating protein (ARF-GAP). Although best known for its role in cell migration, we recently showed that the ability of Cat-1 to bind paxillin, a major constituent of focal complexes, was also essential for the anchorage-independent growth of HeLa cervical carcinoma cells. Here, we set out to learn more about the underlying mechanism by which Cat-paxillin interactions mediate this effect...

: Methyl-CpG-binding domain 1 (MBD1) belongs to a family of methyl-CpG-binding proteins that are epigenetic "readers" linking DNA methylation to transcriptional regulation. MBD1 is expressed in neural stem cells residing in the dentate gyrus of the adult hippocampus (aNSCs) and MBD1 deficiency leads to reduced neuronal differentiation, impaired neurogenesis, learning deficits, and autism-like behaviors in mice; however, the precise function of MBD1 in aNSCs remains unexplored. Here, we show that MBD1 is important for maintaining the integrity and stemness of NSCs, which is critical for their ability to generate neurons...

The increasing numbers of aging and chronically ill prisoners incarcerated in Western nations is well-documented, as is the growing need for prison-based palliative and end-of-life care. Less often discussed is specifically how end-of-life care can and should be provided, by whom, and with what resources. One strategy incorporates prisoner volunteers into end-of-life services within a peer-care program. This article reports on one such program based on focused ethnographic study including in-depth interviews with inmate hospice volunteers, nursing staff, and corrections officers working in the hospice program...

OBJECTIVES: Parkinson's disease (PD) is a progressive neurological disorder associated with motor disabilities and cognitive dysfunction as well. Evidence indicates that PD occurs less frequently in women than men, confirming a role for steroid hormones in protection of dopaminergic nigrostriatal neurons. It is reported that soy genistein, an estrogen agonist phytoestrogen, display neuroprotective effects against neuronal death. In this study we evaluated the effect of genistein in animal models of Parkinsonism (P) and Parkinsonism + ovariectomized (OP)...

Nicole R Tackmann, Yanping Zhang
It is evident that p53 activity is critical for tumor prevention and stress response through its transcriptional activation of genes affecting cellular senescence, apoptosis, cellular metabolism, and DNA repair. The regulation of p53 is highly complex, and MDM2 and MDMX are thought to be critical for deciding the fate of p53, both through inhibitory binding and posttranslational modification. Many mouse models have been generated to study the regulation of p53 in vivo, and they have altered our interpretations of how p53 is regulated by MDM2 and MDMX...
