Analysis of Change in Central Texas Using Image Differencing and Unsupervised Classification

An image differencing algorithm was applied to two Landsat MSS scenes in central Texas to assess its ability to identify change in the greater Austin, Texas metropolitan area. Near infrared data from a Landsat MSS scene acquired September 9, 1972 were subtracted from a Landsat MSS scene acquired August 24, 1990 to produce a difference image representing change in and around Austin, Texas covering a twenty year period. Results indicate that use of empirical analysis to visually identify change within a difference image is highly effective. Unsupervised classification of a difference image to identify change is dependent upon time requirements and the sensitivity of the classified image. While an unsupervised classification of a difference image with a small number of classes was shown to be time saving, it was determined to possess less subtle areas of change. Therefore, it became evident that the greater number of classes used resulted in a higher degree of identified subtle areas of change

miR-196b target screen reveals mechanisms maintaining leukemia stemness with therapeutic potential.

We have shown that antagomiR inhibition of miRNA miR-21 and miR-196b activity is sufficient to ablate MLL-AF9 leukemia stem cells (LSC) in vivo. Here, we used an shRNA screening approach to mimic miRNA activity on experimentally verified miR-196b targets to identify functionally important and therapeutically relevant pathways downstream of oncogenic miRNA in MLL-r AML. We found Cdkn1b (p27Kip1) is a direct miR-196b target whose repression enhanced an embryonic stem cell–like signature associated with decreased leukemia latency and increased numbers of leukemia stem cells in vivo. Conversely, elevation of p27Kip1 significantly reduced MLL-r leukemia self-renewal, promoted monocytic differentiation of leukemic blasts, and induced cell death. Antagonism of miR-196b activity or pharmacologic inhibition of the Cks1-Skp2–containing SCF E3-ubiquitin ligase complex increased p27Kip1 and inhibited human AML growth. This work illustrates that understanding oncogenic miRNA target pathways can identify actionable targets in leukemia

River Flows and Water Wars: Emerging Science for Environmental Decision Making

Real and apparent conflicts between ecosystem and human needs for fresh water are contributing to the emergence of an alternative model for conducting river science around the world. The core of this new paradigm emphasizes the need to forge new partnerships between scientists and other stakeholders where shared ecological goals and river visions are developed, and the need for new experimental approaches to advance scientific understanding at the scales relevant to whole-river management. We identify four key elements required to make this model succeed: existing and planned water projects represent opportunities to conduct ecosystem-scale experiments through controlled river flow manipulations; more cooperative interactions among scientists, managers, and other stakeholders are critical; experimental results must be synthesized across studies to allow broader generalization; and new, innovative funding partnerships are needed to engage scientists and to broadly involve the government, the private sector, and NGOs

Twelve tips for organising speed mentoring events for healthcare professionals at small or large-scale venues

Mentors play a critical role in the development of professionals, influencing their job satisfaction, career aspirations and evolving professional identity. A variety of mentoring models exist, each with distinct benefits and challenges. Speed mentoring, based on the concept of speed dating, provides mentees with opportunities to meet multiple mentors over a short time and pose focussed career development questions. At large-scale events such as the annual AMEE (Association for Medical Education in Europe) meeting, speed mentoring sessions can successfully connect aspiring, novice and mid-career educators with international educational leaders to facilitate transfer of valuable insights for professional growth. For some mentors and mentees, this might spur ongoing communications or even longitudinal relationships. In this paper, we aim to provide strategies for planning and implementing speed mentoring events, combining insights gained from the literature and our experience of organising speed mentoring at the 2019 AMEE meeting in Vienna. These tips will be useful to a variety of professionals planning to organise speed mentoring initiatives

Marginal folate inadequacy observed in a group of young children in Kwangju, Korea

Folate is important for multiple metabolic processes such as nucleic acid synthesis and interconversions, and cell division. Folate deficiency may be a risk factor for several pathologies, such as neural tube birth defects, dementia, and cardiovascular diseases. The objectives of this study were to estimate folate intakes and plasma concentrations of young children living in Kwangju, Korea. Three consecutive 24-h food recalls and fasting blood samples were obtained from 24 boys and 30 girls, aged 2-6 y, living in Kwangju, Korea. The daily folate intake (mean ± SD) of the children was 146.7 ± 73.6 µg dietary folate equivalents. No differences in folate intakes were observed by gender (p≥0.05). The mean folate intakes of the 2 and 3 y old groups were significantly lower (p<0.05) than those of 5 and 6 y old groups. Over half of subjects consumed <Korean Estimated Average Requirements for folate. The plasma folate concentration (mean ± SD) of all subjects was 19.2 ± 8.7 nmol/L, and there was no significant difference by age nor gender (p≥0.05). No significant correlation was observed between folate intakes and plasma folate concentrations. One subject (1.9%) in this study had a plasma folate concentration <6.8 nmol/L, which is indicative of folate deficiency. Approximately 24% of subjects had plasma folate concentrations of 6.8-13.4 nmol/L, which is representative of marginal folate status. In conclusion, some young children may have less than adequate folate status in Korea
