Article Abstract
Objective: To understand the relationship between adolescents' unhealthy snacking behaviour during their school journey and their perceived and objective measures of food outlet availability in the school neighbourhood.
Design: A cross-sectional survey enquired about socio-demographic information, school transport modes, perceived presence of food outlets in the school neighbourhood and unhealthy food purchase and consumption on the school journey. A geographical information system analysis of the food outlets within 500 m and 1000 m school buffers was undertaken. Data were analysed using generalised linear mixed modelling.
Setting: All twelve secondary schools in Dunedin, Aotearoa New Zealand, March 2020-June 2022.
Participants: Adolescents aged 13-18 years ( 725) who reported being familiar with their school neighbourhood.
Results: Perceived availability of food outlets in the school neighbourhood was inversely correlated with distance to the closest food outlet from school and positively correlated with food outlet density within 500 m and 1000 m school buffers. Adolescents' purchase and consumption of unhealthy snacks and drinks during the school journey were associated with perceived availability of food outlets and with shorter distance to the closest food outlet from school. Mixed transport users, girls and those living in high-deprivation neighbourhoods had higher odds of purchasing and consuming unhealthy snacks and drinks during the school journey than active transport users, boys and those living in low-deprivation neighbourhoods, respectively.
Conclusions: Adolescents perceptions of the food environment and close access to food outlets in the school neighbourhood may influence adolescents' food purchase and consumption behaviours during the school journey.

This study investigated the survival dynamics of BG24, a probiotic strain, within reconstituted skim milk (RSM) and yeast extract (YE) matrices during the spray-drying (SD) process, encompassing of inlet/outlet air temperatures. Notably, optimum SD parameters were found to be an inlet air temperature of 150°C and outlet air temperature of 83°C, that achieving high viability (92.23%), and reducing both moisture content (MC) (3.

Background: The food environment plays a crucial role in shaping our dietary choices and overall health. Spatial measures provide distinct perspectives on the physical food environment and its impact on diet. While proportion measures are theoretically considered to provide a more accurate representation of the overall physical food environment than density measures, it is important to recognize that the association between food environments and diet can vary depending on the context.

Sugarcane industries, like other agro-food industries, generate significant volumes of wastewater containing high concentrations of organic and inorganic pollutants. Among the proposed treatment solutions, the anaerobic membrane bioreactor (AnMBR) has proven highly effective in degrading organic pollutants but has limitations in removing color and inorganic pollutants. To address this gap, integrating other technologies with AnMBR is necessary.

Background/objectives: Unhealthy dietary habits are associated with chronic non-communicable diseases and may contribute to increased mortality in all countries of the world. Food environments determine the accessibility, availability, and promotion of food, thus playing an important role in people's diets, but they are context-dependent. The aim of this study was to evaluate the availability and accessibility of food in food outlets in different neighborhoods of the city of Alicante.

Diffusion is defined as general mechanism for drug release from advanced delivery systems, yet dynamic structure of dosage form intrinsically plays an unknown role. The synchrotron radiation X-ray micro-computed tomography (SR-μCT) three-dimensional (3D) imaging and in-depth analysis of 3D structures were applied to readily differentiate materials and accurately capture internal structure changes of multiple unit pellet system (MUPS) and the constituent pellets, visualizing internal 3D structure of a MUPS of theophylline tablets for their 3 levels hierarchy structures: pellets with rapid drug release characteristics, a protective cushion layer and a matrix layer. Drug release pathways were extracted from SR-μCT images and a 3D maze network was constructed using pore network analysis to quantify the internal structural evolution during drug release.
