Calculation problems such as "12x7÷3" can be solved rapidly and easily by using certain techniques; we call these problems "efficient calculation problems." However, it has been pointed out that many students do not always solve them efficiently. In the present study, we examined the effects of an intervention on 35 seventh grade students (23 males, 12 females). The students were instructed to use an overview strategy that stated, "Think carefully about the whole expression", and were then taught three sub-strategies. The results showed that students solved similar problems efficiently after the intervention and the effects were preserved for five months.

Artificial sweeteners have emerged as popular alternatives to traditional sweeteners, driven by the growing concern over sugar consumption and its associated rise in obesity and metabolic disorders. Despite their widespread use, the safety and health implications of artificial sweeteners remain a topic of debate, with conflicting evidence contributing to uncertainty about their long-term effects. This review synthesizes current scientific evidence regarding the impact of artificial sweeteners on gut microbiota and gastrointestinal health.

Objectives: Supervised toothbrushing programmes (STPs), whereby children brush their teeth at nursery or school with a fluoride toothpaste under staff supervision, are a clinically and cost-effective intervention to reduce dental caries. However, uptake is varied, and the reasons unknown. The aim was to use an implementation science approach to explore the perspectives of key stakeholders on the barriers and facilitators at each level of implementation of STPs.

Background: Central venous access devices (CVAD) are widely used in patient care, providing an essential, reliable pathway for patients to receive chemotherapy, long-term infusions, and nutritional support. However, a system of exercise management has not been developed in patients with CVAD.
Purpose: To evaluate and summarize the evidence for management exercise in patients with CVAD and provide guidance for clinical practice.

Introduction: The indication for endoscopic third ventriculostomy is often contested in children younger than 1 year. This study aims to establish the benefits of this modality in children with idiopathic congenital aqueductal stenosis.
Methods: Retrospective analysis was performed on patients <1 year old with idiopathic congenital aqueductal stenosis undergoing endoscopic third ventriculostomy between 2004 and 2020.

Capillary vibrating sharp-edge spray ionization (cVSSI) has been used to control the droplet charging of nebulized microdroplets and monitor effects on protein ion conformation makeup as determined by mass spectrometry (MS). Here it is observed that the application of voltage results in noticeable differences to the charge state distributions (CSDs) of ubiquitin ions. The data can be described most generally in three distinct voltage regions: Under low-voltage conditions (<+200 V, LV regime), low charge states (2+ to 4+ ions) dominate the mass spectra.
