Projections of the future path of the gender wage gap in Great Britain

Purpose &ndash; The paper attempts to project the future trend of the gender wage gap in Great Britain up to 2031.Design/methodology/approach &ndash; The empirical analysis utilises the British Household Panel Study Wave F together with Office for National Statistics (ONS) demographic projections. The methodology combines the ONS projections with assumptions relating to the evolution of educational attainment in order to project the future distribution of human capital skills and consequently the future size of the gender wage gap.Findings &ndash; The analysis suggests that gender wage convergence will be slow, with little female progress by 2031 unless there is a large rise in returns to female experience.Originality/value &ndash; The paper has projected the pattern of male and female skill acquisition together with the associated trend in wages up to 2031.<br /

Engaging Communities to Enhance Physical Activity among Urban Youth

As part of a USDA multi-year grant, this project has used community-based participatory strategies to help overcome barriers to eating more fruits and vegetables and increasing physical activity, and ultimately sparking youth to create healthy communities for a lifetime. The project supports teams of community and school partners in limited income neighborhoods. Obesity is a multifaceted, complex problem, but a sedentary lifestyle is a major contributor to this national health issue. Approximately one-third of children nationwide are overweight or obese; and minority children and those with a low socioeconomic status have the highest prevalence rates. Urban youth have been shown to be less physically active than rural youth. Supportive physical activity environments (understood as the geography, observations, and perceptions of features such as recreational facilities, sidewalks, bike lanes, traffic patterns, etc.) have been positively associated with adolescent physical activity behaviors within urban settings. As part of a socio-ecological intervention to improve physical activity behavior, the Physical Activity Resource Assessment (PARA), the Active Neighborhood Checklist (ANC), and focus groups to assess the physical activity influences within an urban middle school and surrounding community were completed. The assessments suggested that lack of parks, lack of walkability in the streets, perceptions of crime, lack of school programs, and parental and peer influences were all barriers to physical activity opportunities. The ANC, PARA and focus groups each added valuable information for program planning to improve adolescent physical activity behavior. From our initial experiences, environmental audits and focus groups are relatively easy to conduct by Extension professionals, working in partnership with a school and community team, and support a socio-ecological approach to improving physical activity with an urban setting.AUTHOR AFFILIATION: Susan Zies, Educator, The Ohio State University Extension, [email protected] (Corresponding Author); Tandalayo Kidd, Extension Specialist, Kansas State University Extension; Kendra Kattelmann, Professor, South Dakota State University; Dan Remley, Field Specialist, Food, Nutrition and Wellness, The Ohio State University Extension; Erika Lindshield, Extension Associate/Project Coordinator, Kansas State University; Nancy Muturi, Professor, Kansas State University; Koushik Adhikari, Assistant Professor, University of Georgia; Beth Stefura, Educator, The Ohio State University Extension; Marcia Jess, Program Coordinator, The Ohio State University Extension; Shannon Smith, Program Assistant, The Ohio State University Extension.A physical activity environmental assessment using the Physical Activity Resource Assessment and the Active Neighborhood Checklist instruments was completed as part of a United States Department of Agriculture grant targeting obesity in sixth- to eighth-grade students in an urban middle school. The assessments provided baseline data about the physical environments such as recreational facilities, sidewalk, bike lanes, and traffic patterns, in the neighborhood around the urban middle school identified in the project. Focus groups were conducted with adults and with youth to determine perceptions of physical activity in the neighborhood. The focus group data added valuable insight beyond the physical activity environmental assessment. Crime was a major concern among focus group participants as well as lack of non-competitive physical activity opportunities

Computational strategies for dissecting the high-dimensional complexity of adaptive immune repertoires

The adaptive immune system recognizes antigens via an immense array of antigen-binding antibodies and T-cell receptors, the immune repertoire. The interrogation of immune repertoires is of high relevance for understanding the adaptive immune response in disease and infection (e.g., autoimmunity, cancer, HIV). Adaptive immune receptor repertoire sequencing (AIRR-seq) has driven the quantitative and molecular-level profiling of immune repertoires thereby revealing the high-dimensional complexity of the immune receptor sequence landscape. Several methods for the computational and statistical analysis of large-scale AIRR-seq data have been developed to resolve immune repertoire complexity in order to understand the dynamics of adaptive immunity. Here, we review the current research on (i) diversity, (ii) clustering and network, (iii) phylogenetic and (iv) machine learning methods applied to dissect, quantify and compare the architecture, evolution, and specificity of immune repertoires. We summarize outstanding questions in computational immunology and propose future directions for systems immunology towards coupling AIRR-seq with the computational discovery of immunotherapeutics, vaccines, and immunodiagnostics.Comment: 27 pages, 2 figure

Origins of the Tumor Microenvironment: Quantitative Assessment of Adipose-Derived and Bone Marrow–Derived Stroma

To meet the requirements for rapid tumor growth, a complex array of non-neoplastic cells are recruited to the tumor microenvironment. These cells facilitate tumor development by providing matrices, cytokines, growth factors, as well as vascular networks for nutrient and waste exchange, however their precise origins remain unclear. Through multicolored tissue transplant procedures; we have quantitatively determined the contribution of bone marrow-derived and adipose-derived cells to stromal populations within syngeneic ovarian and breast murine tumors. Our results indicate that subpopulations of tumor-associated fibroblasts (TAFs) are recruited from two distinct sources. The majority of fibroblast specific protein (FSP) positive and fibroblast activation protein (FAP) positive TAFs originate from mesenchymal stem/stromal cells (MSC) located in bone marrow sources, whereas most vascular and fibrovascular stroma (pericytes, α-SMA+ myofibroblasts, and endothelial cells) originates from neighboring adipose tissue. These results highlight the capacity for tumors to utilize multiple sources of structural cells in a systematic and discriminative manner

The prevalence of approximal caries in patients after fixed orthodontic treatment and in untreated subjects : A retrospective, cross-sectional study on bitewing radiographs

OBJECTIVE: The aim of this retrospective, cross-sectional study was to investigate the prevalence of approximal carious lesions in patients after fixed multibracket therapy and in subjects without orthodontics on bitewing radiographs. MATERIAL AND METHODS: Bitewing radiographs of 104 orthodontically treated patients with fixed multibracket appliances were compared to those of 111 untreated subjects. The individuals in both groups were between 15 and 16.25 years of age when radiographs were taken. The test group with orthodontics was recruited from the archive of the Department of Orthodontics at the University of Zürich. The untreated control group was selected randomly from 16 communities in the Canton of Zürich. The approximal surfaces of the permanent premolars and molars of all subjects were assessed by two calibrated investigators. RESULTS: The average number of enamel lesions in the test group after fixed orthodontic treatment was lower than in the control group (0.57 vs. 1.85, p < 0.001). The same was found for dentin lesions (0.06 vs. 0.49, p < 0.001). The distribution of lesions was similar in both groups. CONCLUSION: Fewer approximal carious lesions were detected in the test group after fixed multibracket appliances than in the age-matched control group without orthodontic treatment

From proteomic analysis to potential therapeutic targets: functional profile of two lung cancer cell lines, A549 and SW900, widely studied in pre-clinical research

Lung cancer is a serious health problem and the leading cause of cancer death worldwide. The standard use of cell lines as in vitro pre-clinical models to study the molecular mechanisms that drive tumorigenesis and access drug sensitivity/effectiveness is of undisputable importance. Label-free mass spectrometry and bioinformatics were employed to study the proteomic profiles of two representative lung cancer cell lines and to unravel the specific biological processes. Adenocarcinoma A549 cells were enriched in proteins related to cellular respiration, ubiquitination, apoptosis and response to drug/hypoxia/oxidative stress. In turn, squamous carcinoma SW900 cells were enriched in proteins related to translation, apoptosis, response to inorganic/organic substances and cytoskeleton organization. Several proteins with differential expression were related to cancer transformation, tumor resistance, proliferation, migration, invasion and metastasis. Combined analysis of proteome and interactome data highlighted key proteins and suggested that adenocarcinoma might be more prone to PI3K/Akt/mTOR and topoisomerase IIα inhibitors, and squamous carcinoma to Ck2 inhibitors. Moreover, ILF3 overexpression in adenocarcinoma, and PCNA and NEDD8 in squamous carcinoma shows them as promising candidates for therapeutic purposes. This study highlights the functional proteomic differences of two main subtypes of lung cancer models and hints several targeted therapies that might assist in this type of cancer.publishe

AD51B in Familial Breast Cancer

Common variation on 14q24.1, close to RAD51B, has been associated with breast cancer: rs999737 and rs2588809 with the risk of female breast cancer and rs1314913 with the risk of male breast cancer. The aim of this study was to investigate the role of RAD51B variants in breast cancer predisposition, particularly in the context of familial breast cancer in Finland. We sequenced the coding region of RAD51B in 168 Finnish breast cancer patients from the Helsinki region for identification of possible recurrent founder mutations. In addition, we studied the known rs999737, rs2588809, and rs1314913 SNPs and RAD51B haplotypes in 44,791 breast cancer cases and 43,583 controls from 40 studies participating in the Breast Cancer Association Consortium (BCAC) that were genotyped on a custom chip (iCOGS). We identified one putatively pathogenic missense mutation c.541C&gt;T among the Finnish cancer patients and subsequently genotyped the mutation in additional breast cancer cases (n = 5259) and population controls (n = 3586) from Finland and Belarus. No significant association with breast cancer risk was seen in the meta-analysis of the Finnish datasets or in the large BCAC dataset. The association with previously identified risk variants rs999737, rs2588809, and rs1314913 was replicated among all breast cancer cases and also among familial cases in the BCAC dataset. The most significant association was observed for the haplotype carrying the risk-alleles of all the three SNPs both among all cases (odds ratio (OR): 1.15, 95% confidence interval (CI): 1.11–1.19, P = 8.88 x 10−16) and among familial cases (OR: 1.24, 95% CI: 1.16–1.32, P = 6.19 x 10−11), compared to the haplotype with the respective protective alleles. Our results suggest that loss-of-function mutations in RAD51B are rare, but common variation at the RAD51B region is significantly associated with familial breast cancer risk

Velocity-space sensitivity of the time-of-flight neutron spectrometer at JET

The velocity-space sensitivities of fast-ion diagnostics are often described by so-called weight functions. Recently, we formulated weight functions showing the velocity-space sensitivity of the often dominant beam-target part of neutron energy spectra. These weight functions for neutron emission spectrometry (NES) are independent of the particular NES diagnostic. Here we apply these NES weight functions to the time-of-flight spectrometer TOFOR at JET. By taking the instrumental response function of TOFOR into account, we calculate time-of-flight NES weight functions that enable us to directly determine the velocity-space sensitivity of a given part of a measured time-of-flight spectrum from TOFOR
