Cultural Heritage Initiative Feasibility Assessment: Centralia, Pennsylvania
The thesis of the project is that the region of Mount Carmel, PA, could better benefit from the influx of tourists that comes in daily for Centralia if there is a structural architecture to present and preserve the cultural heritage of Centralia and the immediate region. The impact of this initiative relies upon the relationship that the surrounding communities of the lower Anthracite coal region have with each other in their interconnected histories. The goal of this report is to assess the feasibility of revitalizing the anthracite coal region by preserving the cultural heritage of Centralia as a protected state park. This report provides the groundwork for a three-fold impact:
1) Providing the potential framework to help capture and promote the influx of tourism into the region in a respectful and proactive way that highlights Centraliaâs rich history.
2) Preserve and celebrate the historical culture of the Anthracite coal region and communities surrounding Centralia.
3) Encourage economic growth through touristic markets and support services

Exercise-Induced Changes in Exhaled NO Differentiates Asthma With or Without Fixed Airway Obstruction From COPD With Dynamic Hyperinflation.
Asthmatic patients with fixed airway obstruction (FAO) and patients with chronic obstructive pulmonary disease (COPD) share similarities in terms of irreversible pulmonary function impairment. Exhaled nitric oxide (eNO) has been documented as a marker of airway inflammation in asthma, but not in COPD. To examine whether the basal eNO level and the change after exercise may differentiate asthmatics with FAO from COPD, 27 normal subjects, 60 stable asthmatics, and 62 stable COPD patients were studied. Asthmatics with FAO (nâ=â29) were defined as showing a postbronchodilator FEV(1)/forced vital capacity (FVC) â€70% and FEV(1) less than 80% predicted after inhaled salbutamol (400âÎŒg). COPD with dynamic hyperinflation (nâ=â31) was defined as a decrease in inspiratory capacity (ÎIC%) after a 6 minute walk test (6MWT). Basal levels of eNO were significantly higher in asthmatics and COPD patients compared to normal subjects. The changes in eNO after 6MWT were negatively correlated with the percent change in IC (râ=ââ0.380, nâ=â29, Pâ=â0.042) in asthmatics with FAO. Their levels of basal eNO correlated with the maximum mid-expiratory flow (MMEF % predicted) before and after 6MWT. In COPD patients with air-trapping, the percent change of eNO was positively correlated to ÎIC% (rsâ=â0.404, nâ=â31, Pâ=â0.024). We conclude that asthma with FAO may represent residual inflammation in the airways, while dynamic hyperinflation in COPD may retain NO in the distal airspace. eNO changes after 6MWT may differentiate the subgroups of asthma or COPD patients and will help toward delivery of individualized therapy for airflow obstruction
Prenatal Diagnosis of Agenesis of the Corpus Callosum and Cerebellar Vermian Hypoplasia Associated with a Microdeletion on Chromosome 1p32
We present the prenatal detection of a 1p32.1p31.3 microdeletion (3.46 Mb) by array comparative genomic hybridization (CGH) associated with fetal agenesis of the corpus callosum (ACC) and cerebellar vermian hypoplasia. Analysis of cultured amniocytes showed a normal karyotype. Our observations strengthen the association between this locus and central nervous system development. In addition, the fetus reported herein underscores the importance of array CGH analysis when ACC is detected prenatally, especially when there are additional central nervous system anomalies, to search for submicroscopic imbalances which can facilitate further management and parental counselling. Moreover, the presence of urinary tract anomalies should alert the clinician to the possibility of a 1p interstitial deletion, although the absence of such does not exclude it. Further reports will help to provide more information on the long-term outcomes of individuals with such microdeletion as there are only limited data.published_or_final_versio

C5 Extract Induces Apoptosis in B16F10 Murine Melanoma Cells through Extrinsic and Intrinsic Apoptotic Pathways and Sub-G1 Phase Arrest
Purpose: To investigate the anti-cancer activities of C5 extract (C5E), a new herbal preparation from Korea, on B16F10 cells.Methods: The anti-proliferative effects of C5E were assessed by culturing B16F10 cells in the presence or absence of C5E. Cell cycle progression was analyzed by PI staining using flow cytometry. The quantities of apoptosis-inducing proteins were measured by Western blot.Results: C5E inhibited the proliferation of B16F10 cells but not human keratinocytes. C5E induced S phase arrest by interfering with cell regulatory factors such as cyclins B1, D1, D3, and E, and cyclindependent kinase 2, in B16F10 cells. Furthermore, immunoblot analysis confirmed that treatment with C5E induced apoptosis and cleaved caspase-3, poly (ADP-ribose) polymerase, via extrinsic pathway, whereas Bcl-2 expression was down-regulated. In addition, the suppression of cell proliferation by C5E is through down-regulation of p-Akt, up-regulation of phosphatase and tensin homolog protein expression via phosphoinositol 3 kinase survival signaling pathways in B16F10 cells. The combined cytotoxic effects of C5E and vinblastine generated 10 % increase in activity in contrast to the sum of the inhibitory effects of the individual agents.Conclusion: C5E shows promising anti-cancer activity and can be a useful adjuvant with vinblastine in combination therapeutic treatment of skin cancer.Keywords: Melanoma, Apoptosis, Anti-cancer, p53, Vinblastine, Cell cycle arrest, Caspas
Effectiveness of the Tier 1 Program of Project P.A.T.H.S.: Objective outcome evaluation based on a randomized group trial
Copyright © 2008 with author(s). There are two tiers of programs in the Project P.A.T.H.S. (Positive Adolescent Training through Holistic Social Programs). In the Tier 1 Program, teaching units based on different positive youth development constructs are covered. A total of 24 experimental schools (N = 4,121 students) and 24 control schools (N = 3,854 students) were randomly selected to participate in a randomized group trial. Analyses of covariance and linear mixed models controlling for differences between the two groups in terms of pretest scores, personal variables, and random effects of schools showed that participants in the experimental schools had significantly higher positive youth development levels than did participants in the control schools at post-test based on different indicators derived from the Chinese Positive Youth Development Scale. In conjunction with other evaluation findings reported previously, the present study suggests that the Tier 1 Program of P.A.T.H.S. promotes the positive development of Chinese adolescents in Hong Kong. ©2008 with author.

Discovering monotonic stemness marker genes from time-series stem cell microarray data
© 2015 Wang et al.; licensee BioMed Central Ltd. Background: Identification of genes with ascending or descending monotonic expression patterns over time or stages of stem cells is an important issue in time-series microarray data analysis. We propose a method named Monotonic Feature Selector (MFSelector) based on a concept of total discriminating error (DEtotal) to identify monotonic genes. MFSelector considers various time stages in stage order (i.e., Stage One vs. other stages, Stages One and Two vs. remaining stages and so on) and computes DEtotal of each gene. MFSelector can successfully identify genes with monotonic characteristics.Results: We have demonstrated the effectiveness of MFSelector on two synthetic data sets and two stem cell differentiation data sets: embryonic stem cell neurogenesis (ESCN) and embryonic stem cell vasculogenesis (ESCV) data sets. We have also performed extensive quantitative comparisons of the three monotonic gene selection approaches. Some of the monotonic marker genes such as OCT4, NANOG, BLBP, discovered from the ESCN dataset exhibit consistent behavior with that reported in other studies. The role of monotonic genes found by MFSelector in either stemness or differentiation is validated using information obtained from Gene Ontology analysis and other literature. We justify and demonstrate that descending genes are involved in the proliferation or self-renewal activity of stem cells, while ascending genes are involved in differentiation of stem cells into variant cell lineages.Conclusions: We have developed a novel system, easy to use even with no pre-existing knowledge, to identify gene sets with monotonic expression patterns in multi-stage as well as in time-series genomics matrices. The case studies on ESCN and ESCV have helped to get a better understanding of stemness and differentiation. The novel monotonic marker genes discovered from a data set are found to exhibit consistent behavior in another independent data set, demonstrating the utility of the proposed method.

Retaining Adolescent and Young Adult Participants in Research During a Pandemic: Best Practices From Two Large-Scale Developmental Neuroimaging Studies (NCANDA and ABCD)
The novel coronavirus pandemic that emerged in late 2019 (COVID-19) has created challenges not previously experienced in human research. This paper discusses two large-scale NIH-funded multi-site longitudinal studies of adolescents and young adults â the National Consortium on Alcohol and Neurodevelopment in Adolescence (NCANDA) and the Adolescent Brain Cognitive Development (ABCD) Study â and valuable approaches to learn about adaptive processes for conducting developmentally sensitive research with neuroimaging and neurocognitive testing across consortia during a global pandemic. We focus on challenges experienced during the pandemic and modifications that may guide other projects, such as implementing adapted protocols that protect the safety of participants and research staff, and addressing assessment challenges through the use of strategies such as remote and mobile assessments. Given the pandemicâs disproportionate impacts on participants typically underrepresented in research, we describe efforts to retain these individuals. The pandemic provides an opportunity to develop adaptive processes that can facilitate future studiesâ ability to mobilize effectively and rapidly
