Background: National Nutritional Standards for school lunches were reintroduced in 2001, and included guidance on portion sizes for primary schools. For the first time since 1997, nationally representative data on school food portion sizes in England have been collected using direct assessment rather than reported portion sizes.
Methods: Food portions were weighed directly in foods served in nationally representative samples of primary and secondary school meals. Results were grouped by food or food group.
Results: The number of portions weighed was 7975 in primary schools and 3354 in secondary schools. Individual portion weights were grouped by food or food group to yield mean, median, SD and inter-quartile range. For a given food or food group, the number of portions weighed varied from 5 to 210 portions in primary schools and between 5 and 194 portions in secondary schools.
Conclusions: The results provide a good representation of typical portion weights for different foods and food groups in primary and secondary schools in England. Portion size is one factor that determines nutrient intake. New standards for school lunches are both nutrient and food-based. Guidance on portion weights will help to ensure that pupils consume the correct balance of foods to obtain the recommended nutrient intake. The present findings complement and extend existing guidance on portion sizes for pupils in schools in England and Scotland.

Unlabelled: Cancer cachexia, a multifactorial condition resulting in muscle and adipose tissue wasting, reduces the quality of life of many people with cancer. Despite decades of research, therapeutic options for cancer cachexia remain limited. Cachexia is highly prevalent in people with pancreatic ductal adenocarcinoma (PDAC), and many animal models of pancreatic cancer are used to understand mechanisms underlying cachexia.

Background: Social media platforms have become integral to daily life and increasingly disseminate health, nutrition, and food information. While these platforms can offer evidence-based nutrition education and meal planning guidance, a significant portion of content promotes unrealistic beauty standards and unhealthy weight-loss practices, potentially contributing to disordered eating behaviors. The increasing prevalence of disordered eating, characterized by abnormal eating behaviors and attitudes, has become a global public health concern.

The molecular chains of recycled polyethylene terephthalate (rPET) show breakage during daily use, causing poor crystallization and leading to mechanical properties that, when blended with the nucleating agent, become an effective method of solving this problem. The salt-nucleating agent sodium benzoate (SB), disodium terephthalate (DT), and trisodium 1,3,5benzene tricarboxylic (TBT) were synthesized, and an rPET/nucleating agent blend was prepared. The intrinsic viscosity () results showed that the of the rPET/SB was decreased, which indicated the breakage of the rPET molecular chains.

European guidelines recommend surgical management at specific weight and comorbidity level; however, less than 2% of eligible patients undergo surgical bariatric interventions. To extend the benefits of bariatric interventions to the untreated population with obesity, endoscopic techniques such as endoscopic sleeve gastroplasty (ESG) have been developed.

Many synaptic vesicles undergo exocytosis in motor nerve terminals during neuromuscular communication. Endocytosis then recovers the synaptic vesicle pool and presynaptic membrane area. The kinetics of endocytosis may shape neuromuscular transmission, determining its long-term reliability.
