Background: Mozambique's ministry of health (MOH) recognized the need to establish a national laboratory quality assurance (NLQA) program to improve the reliability and accuracy of laboratory testing. The Becton Dickinson-US President's Emergency Plan for AIDS Relief Public-Private Partnership (PPP) was used to garner MOH commitment and train a cadre of local auditors and managers to support sustainability and country ownership of a NLQA program.
Methods: From January 2011 to April 2012, the World Health Organization Regional Office for Africa Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) checklist and the Strengthening Laboratory Management Towards Accreditation (SLMTA) curriculum were used in 6 MOH laboratories. PPP volunteers provided training and mentorship to build the capacity of local auditors and program managers to promote institutionalization and sustainability of the program within the MOH.
Results: SLIPTA was launched in 6 MOH laboratories, and final audits demonstrated improvements across the 13 quality system essentials, compared with baseline. Training and mentorship of MOH staff by PPP volunteers resulted in 18 qualified auditors and 28 managers/quality officers capacitated to manage the improvement process in their laboratories.
Conclusions: SLIPTA helps laboratories improve the quality and reliability of their service even in the absence of full accreditation. Local capacity building ensures sustainability by creating country buy-in, reducing costs of audits, and institutionalizing program management.

Objective: To explore the clinical value of combining split-bolus contrast injection with dual-energy CT(DECT) scanning technology in pediatric computed tomography urography (CTU) imaging.
Methods: A total of 128 children aged 0-17 years were prospectively selected and randomly assigned to three groups: A, B, and C. For Group A, a high-pitch flash mode was employed, where a single bolus of contrast agent was followed by four-phase scanning (noncontrast, cortex, medulla, and excretory phases).

Two-dimensional Transition Metal Dichalcogenides (2D TMDs) have garnered significant attention in the field of materials science due to their remarkable electronic and optoelectronic properties, including high carrier mobility and tunable band gaps. Despite the extensive research on various TMDs, there remains a notable gap in understanding the synthesis techniques and their implications for the practical application of monolayer tungsten disulfide (WS2) in optoelectronic devices. This gap is critical, as the successful integration of WS2 into commercial technologies hinges on the development of reliable synthesis methods that ensure high quality and uniformity of the material.

Introduction: Post-stroke movement disorders are common, especially upper limb dysfunction, which seriously affects the physical and mental health of stroke patients. With the continuous development of intelligent technology, robot-assisted therapy has become a research hotspot in the upper limb rehabilitation of stroke patients in recent years. Many scholars have also integrated robot-assisted therapy with other interventions to improve rehabilitation outcomes.

Aspartate (Asp) metabolism-mediated antioxidant functions have important implications for neonatal growth and intestinal health; however, the antioxidant mechanisms through which Asp regulates the gut microbiota and influences RIP activation remain elusive. This study reports that chronic oxidative stress disrupts gut microbiota and metabolite balance and that such imbalance is intricately tied to the perturbation of Asp metabolism. Under normal conditions, in vivo and in vitro studies reveal that exogenous Asp improves intestinal health by regulating epithelial cell proliferation, nutrient uptake, and apoptosis.
