Obesity impacts the regulation of miR-10b and its targets in primary breast tumors
Obesity increases breast cancer (BC) risk in post-menopausal women by mostly unknown molecular mechanisms which may partly be regulated by microRNAs (miRNAs). We isolated RNA from paired benign and malignant biopsies from 83 BC patients and determined miRNA profiles in samples from 12 women at the extremes of the BMI distribution by RNA-seq. Candidates were validated in all samples. Associations between miR-10b expression and validated target transcript levels, and effects of targeted manipulation of miR-10b levels in a primary BC cell line on proliferation and invasion potential, were explored.This article is freely available via Open Access.

Advantages and Limitations of Commercially Available Electrocuting Grids for Studying Mosquito Behaviour.
Mosquito feeding behaviour plays a major role in determining malaria transmission intensity and the impact of specific prevention measures. Human Landing Catch (HLC) is currently the only method that can directly and consistently measure the biting rates of anthropophagic mosquitoes, both indoors and outdoors. However, this method exposes the participant to mosquito-borne pathogens, therefore new exposure-free methods are needed to replace it. Commercially available electrocuting grids (EGs) were evaluated as an alternative to HLC using a Latin Square experimental design in Dar es Salaam, Tanzania. Both HLC and EGs were used to estimate the proportion of human exposure to mosquitoes occurring indoors (πi), as well as its two underlying parameters: the proportion of mosquitoes caught indoors (Pi) and the proportion of mosquitoes caught between the first and last hour when most people are indoors (Pfl). HLC and EGs methods accounted for 69% and 31% of the total number of female mosquitoes caught respectively and both methods caught more mosquitoes outdoors than indoors. Results from the gold standard HLC suggest that An. gambiae s.s. in Dar es Salaam is neither exophagic nor endophagic (Pi ≈ 0.5), whereas An. arabiensis is exophagic (Pi < < 0.5). Both species prefer to feed after 10 pm when most people are indoors (Pfl > >0.5). EGs yielded estimates of Pi for An. gambiae s.s., An. arabiensis and An. coustani, that were approximately equivalent to those with HLC but significantly underestimated Pfl for An. gambiae s.s. and An. coustani. The relative sampling sensitivity of EGs declined over the course of the night (p ≤ 0.001) for all mosquito taxa except An. arabiensis. Commercial EGs sample human-seeking mosquitoes with high sensitivity both indoors and outdoors and accurately measure the propensity of Anopheles malaria vectors to bite indoors rather than outdoors. However, further modifications are needed to stabilize sampling sensitivity over a full nocturnal cycle so that they can be used to survey patterns of human exposure to mosquitoes
The ethics of digital well-being: a multidisciplinary perspective
This chapter serves as an introduction to the edited collection of the same name, which includes chapters that explore digital well-being from a range of disciplinary perspectives, including philosophy, psychology, economics, health care, and education. The purpose of this introductory chapter is to provide a short primer on the different disciplinary approaches to the study of well-being. To supplement this primer, we also invited key experts from several disciplines—philosophy, psychology, public policy, and health care—to share their thoughts on what they believe are the most important open questions and ethical issues for the multi-disciplinary study of digital well-being. We also introduce and discuss several themes that we believe will be fundamental to the ongoing study of digital well-being: digital gratitude, automated interventions, and sustainable co-well-being

A stakeholder co-design approach for developing a community pharmacy service to enhance screening and management of atrial fibrillation
The authors would like to thank all participants in this research for their
valuable input into the co-design process.Background: Community pharmacies provide a suitable setting to promote self-screening programs aimed at
enhancing the early detection of atrial fibrillation (AF). Developing and implementing novel community pharmacy
services (CPSs) is a complex and acknowledged challenge, which requires comprehensive planning and the
participation of relevant stakeholders. Co-design processes are participatory research approaches that can enhance
the development, evaluation and implementation of health services. The aim of this study was to co-design a
pharmacist-led CPS aimed at enhancing self-monitoring/screening of AF.
Methods: A 3-step co-design process was conducted using qualitative methods: (1) interviews and focus group
with potential service users (n = 8) to identify key needs and concerns; (2) focus group with a mixed group of
stakeholders (n = 8) to generate a preliminary model of the service; and (3) focus group with community pharmacy
owners and managers (n = 4) to explore the feasibility and appropriateness of the model. Data were analysed
qualitatively to identify themes and intersections between themes. The JeMa2 model to conceptualize pharmacybased
health programs was used to build a theoretical model of the service.
Results: Stakeholders delineated: a clear target population (i.e., individuals ≥65 years old, with hypertension, with or
without previous AF or stroke); the components of the service (i.e., patient education; self-monitoring at home;
results evaluation, referral and follow-up); and a set of circumstances that may influence the implementation of the
service (e.g., quality of the service, competency of the pharmacist, inter-professional relationships, etc.). A number of
strategies were recommended to enable implementation (e.g.,. endorsement by leading cardiovascular
organizations, appropriate communication methods and channels between the pharmacy and the general medical
practice settings, etc.).
Conclusion: A novel and preliminary model of a CPS aimed at enhancing the management of AF was generated
from this participatory process. This model can be used to inform decision making processes aimed at adopting
and piloting of the service. It is expected the co-designed service has been adapted to suit existing needs of
patients and current care practices, which, in turn, may increase the feasibility and acceptance of the service when
it is implemented into a real setting.This work was funded by Covidien Pty Ltd. (Medtronic Australasia Pty Ltd)

Goal Priming in Dieters: Recent Insights and Applications
What are the psychological mechanisms that make dieting so challenging in our food-rich living environment? Social psychological research on goal priming provides a useful framework for answering this question, as well as implications for how to enhance dieting success. This review presents and discusses recent research which shows that attractive food cues prime the hedonic eating goal in dieters, and thus facilitate overeating. However, external cues priming the goal of weight control can be used to offset these effects and thus to facilitate dieting success, as is demonstrated in both field and laboratory experiments. In addition, recent strategies to prevent hedonic effects of attractive food, such as mindful attention, can facilitate self-regulation. These recent advances in our understanding of dieting behavior have theoretical and practical implications for how successful dieting can be facilitated, both by means of individual strategies, as well as by environmental changes
Out of Mind, Out of Sight: Language Affects Perceptual Vividness in Memory
We examined whether language affects the strength of a visual representation in memory. Participants studied a picture, read a story about the depicted object, and then selected out of two pictures the one whose transparency level most resembled that of the previously presented picture. The stories contained two linguistic manipulations that have been demonstrated to affect concept availability in memory, i.e., object presence and goal-relevance. The results show that described absence of an object caused people to select the most transparent picture more often than described presence of the object. This effect was not moderated by goal-relevance, suggesting that our paradigm tapped into the perceptual quality of representations rather than, for example, their linguistic availability. We discuss the implications of these findings within a framework of grounded cognition
Search for Charged Higgs Bosons in e+e- Collisions at \sqrt{s} = 189 GeV
A search for pair-produced charged Higgs bosons is performed with the L3
detector at LEP using data collected at a centre-of-mass energy of 188.6 GeV,
corresponding to an integrated luminosity of 176.4 pb^-1. Higgs decays into a
charm and a strange quark or into a tau lepton and its associated neutrino are
considered. The observed events are consistent with the expectations from
Standard Model background processes. A lower limit of 65.5 GeV on the charged
Higgs mass is derived at 95 % confidence level, independent of the decay

Maroon Archaeology Beyond the Americas: A View From Kenya
Archaeological research on Maroons—that is, runaway slaves—has been largely confined to the Americas. This essay advocates a more global approach. It specifically uses two runaway slave communities in 19th-century coastal Kenya to rethink prominent interpretive themes in the field, including “Africanisms,” Maroons’ connections to indigenous groups, and Maroon group cohesion and identity. This article’s analysis demonstrates that the comparisons enabled by a more globalized perspective benefit the field. Instead of eliding historical and cultural context, these comparisons support the development of more localized and historically specific understandings of individual runaway slave communities both in Kenya and throughout the New World
