Children's understandings of obesity, a thematic analysis

Childhood obesity is a major concern in today’s society. Research suggests the inclusion of the views and understandings of a target group facilitates strategies that have better efficacy. The objective of this study was to explore the concepts and themes that make up children’s understandings of the causes and consequences of obesity. Participants were selected from Reception (4-5 years old) and Year 6 (10-11 years old), and attended a school in an area of Sunderland, in North East England. Participants were separated according to age and gender, resulting in four focus groups, run across two sessions. A thematic analysis (Braun & Clarke, 2006) identified overarching themes evident across all groups, suggesting the key concepts that contribute to children’s understandings of obesity are ‘‘Knowledge through Education,’’ ‘‘Role Models,’’ ‘‘Fat is Bad,’’ and ‘‘Mixed Messages.’’ The implications of these findings and considerations of the methodology are discussed in full

Development and evaluation of floating alginate microspheres for oral delivery of anthocyanins – A preliminary investigation

The goal of this study was to develop floating microspheres that could be used as gastroretentive systems for the delivery of anthocyanins (ACNs). These compounds are absorbed in the stomach and small intestine, and insufficient residence time in these organs could result in limited absorption and contribute to degradation. The microparticles containing freeze‐dried haskap berry extract (321.96 ± 8.35 mg cyanidin 3‐glucoside equivalents per g) were prepared by ionotropic gelation of alginate (9%, w/w) with calcium ions (CaCl2 at 2%, w/v) in the gelation bath, with calcium carbonate as the gas‐generating compound (added at different ratios in the alginate/extract mixture). The effect of acetic acid concentration (2 and 10%, v/v) in the gelation medium was investigated. Increasing the carbonate : alginate weigh ratio from 0 to 3:4 resulted in different degrees of floatability, larger particles, higher encapsulation efficiency, and lower amount of ACN released. The power law equation fitted the experimental data well, indicating that release occurred mainly by diffusion. This is the first time floating microspheres are proposed as gastroretentive platforms for the delivery of ACNs

Adenosine-associated delivery systems.

Adenosine is a naturally occurring purine nucleoside in every cell. Many critical treatments such as modulating irregular heartbeat (arrhythmias), regulation of central nervous system (CNS) activity and inhibiting seizural episodes can be carried out using adenosine. Despite the significant potential therapeutic impact of adenosine and its derivatives, the severe side effects caused by their systemic administration have significantly limited their clinical use. In addition, due to adenosine's extremely short half-life in human blood (<10 s), there is an unmet need for sustained delivery systems to enhance efficacy and reduce side effects. In this article, various adenosine delivery techniques, including encapsulation into biodegradable polymers, cell-based delivery, implantable biomaterials and mechanical-based delivery systems, are critically reviewed and the existing challenges are highlighted

Criminal Justice Officials’ Views of Sex Offenders, Sex Offender Registration, Community Notification, and Residency Restrictions

Despite widespread media attention, research efforts, and political support, there is relatively little known about how individuals who are employed in the criminal justice system perceive the fairness, efficacy, and scope of policies aimed at sex offenders. The present study considers the attitudes and beliefs toward sex offenders and sex offender laws, including registration, community notification, and residency restrictions, held by a diverse sample of criminal justice officials who represent all three major components of the criminal justice system. Findings reveal that variation exists among types of criminal justice officials with respect to their perspectives on sex offenders, and most criminal justice officials endorse the implementation and enforcement of current sex offender laws, despite having doubts about their efficacy
