Poor lifestyle choices in adolescents, including low physical activity (PA), excess screen time, and unhealthy dietary habits, are major threats to their health in the future. Unhealthy behaviors such as insufficient PA, high TV time, and poor dietary choices also tend to cluster, but information on the combined association of screen time, sports participation, and dietary habits is limited in Austrian youth. To examine the association among these behaviors, 165 adolescents (74 girls and 91 boys) between 11 and 14 [...]

Major depressive disorder (MDD) is a debilitating illness that places a great burden on global health. A ketogenic diet, which has traditionally been used for treating refractory epileptic disorders, is being increasingly explored for its potential of alleviating other neuropsychiatric conditions. Providing an up-to-date summary on the ketogenic diet’s potential to alleviate MDD, its neurobiological basis, and preliminary clinical evidence. A structured literature survey was performed, and a narrative review was wr [...]

Parenteral nutrition (PN) is a complex medication administered to adult, pediatric, and neonatal patients. PN is recognized as a high-alert medication by the Institute for Safe Medication Practices (ISMP). The American Society for Parenteral and Enteral Nutrition (ASPEN) has published several key recommendations regarding safe use of PN. This manuscript will review several of the important PN papers published in 2020-2021 by ASPEN.

It is recommended that children ages 3-5 receive 180 minutes of physical activity a day, with at least 60 minutes of moderate-to-vigorous physical activity. Despite these recommendations, a majority of preschoolers are not provided opportunities in the early childhood education setting to meet these daily recommendations through either structured or unstructured physical activity. Accordingly, the number of young children identified as overweight or obese over the past couple of decades has increased. Critical to a [...]

Wheat bran cereals are an important source of dietary fibre. The aim of the study was to investigate if a high intake (120 g) of fibre rich breakfast cereal (which delivers the UK Government guidelines for fibre intake in one serving but is three-fold higher than the manufacturers recommended serving) has additional potential health benefits compared to the recommended serving (40 g, containing 11 g of dietary fibre). To assess this, the study determined the short chain fatty acid (SCFA) profiles in human faecal, u [...]

Poor dietary habits can lead to obesity and insulin resistance—both of which can impair basal heat shock protein (HSP) expression and the HSP stress response in skeletal muscle. It remains unclear if impairments in HSP expression occur during the early stages of diet-induced obesity and metabolic dysfunction. We determined if basal HSP expression (HSP70, HSP60, HSP25) was impaired in sedentary or exercised rats following the onset of diet-induced obesity. Male Long-Evans rats (N=6-7/group) were assigned to a Wester [...]

3-Dimension printing (3-DPT) or additive manufacturing (AM) technology has been utilized for a while in the construction of customized 3-D objects utilizing computer software such as computer-aided design (CAD). However, the emergence of an innovative and new four-dimensional printing (4-DPT) has enabled the synergy of AM technology with programmable materials in transforming digital processes virtually into physical entities, thereby providing innovation and advanced functionalities. 4-DPT is a procedure facilitat [...]

This study investigates the hypothesis that diverse synthesis techniques can yield cellulose-graphene hybrids with tailored properties for specific applications, enabling advancements in flexible electronics, energy storage, environmental remediation, and biomedical devices. We examined and compared multiple synthesis methods, including chemical reduction, in-situ synthesis, green synthesis using natural reducing agents, solvent-assisted approaches, hydrothermal and solvothermal techniques, mechanical and chemical [...]

The widespread usage of various wireless equipment in many facets of life has significantly contributed to the serious pollution caused by electromagnetic radiation. Thankfully, scientists have created materials that can absorb microwave radiation and convert dangerous electromagnetic waves into other forms of energy, including heat energy. Many investigations regarding the development of materials that absorb microwaves with different constituents, morphologies, and architectures have been published recently. Micr [...]

Lead is a non-biodegradable toxic heavy metal. Biosorption process is an attractive technique to remediate lead-contaminated environments because it is simple, effective and low-cost. In addition, rice husk constitutes a highly available residual biomass that could be used as bioadsorbent. Thus, the aim of this study was to analyze the biosorption of lead on natural and chemically treated rice husk and evaluate the incorporation of the residue (biomass-contaminant) into ceramic matrices to immobilize the removed le [...]
