Summary: This study presents a reagentless sample preparation method for the detection of particulate Pb contaminants in tap water using membrane electrolysis. The membrane electrolysis allows for the in-situ generation of nitric acid, which, when combined with anodic stripping voltammetry, provides a powerful and reagent-free detection of Pb2+. The setup configuration enables semi-autonomous operation and requires minimal attention, making it more suitable for continuous measurements of particulate contaminants in tap water.

Summary: In this study, cetyltrimethylammonium bromide and zeolitic imidazolate framework-8 (ZIF-8) were assembled via chemical co-precipitation, and high-quality carbon-based metal-free nanomaterials were synthesized using heat treatment. The internal and morphological characteristics of hexagonal Star ZIF-8 were investigated. An electrochemical sensor with a good response to Cd(II) was prepared using Star ZIF-8 nanomaterial-modified electrodes. The sensitivity of the sensor was increased by five orders of magnitude.

Summary: A novel dynamic method for chemical imaging of actively corroding metal surfaces using CV-SECM and SWV-SECM is proposed. Gold microelectrodes are employed as SECM tips to collect and dissolve Cu2+ ions, enabling the investigation of copper dissolution and electrochemical behavior during mapping of copper surfaces. The results indicate heterogeneous copper degradation and the formation of protective films and passive layers.

Summary: In this study, palladized aluminum was used as a new type of solid electrode for the determination of copper using the differential pulse anodic stripping voltammetry (DPASV) technique. The preparation of the electrode involved electroless deposition of metallic palladium on the aluminum surface, resulting in good sensitivity and selectivity. Various experimental variables were optimized, and under the optimal conditions, a linear calibration graph was achieved for copper concentration determination. The proposed method showed no interference and was successfully applied for determining copper content in nutritional supplement tablets.

Summary: The expression levels of miRNA in the aqueous humor of PEXG patients were evaluated using expression microarray method. Twenty new miRNA molecules potentially associated with the development or progression of PEXG were identified. Functional and enrichment analysis revealed that these miRNAs may regulate mechanisms related to extracellular matrix imbalance, cell apoptosis (possibly retinal ganglion cells), autophagy, and elevated calcium cation levels in PEXG. However, further research is needed to understand the exact molecular basis of PEXG.

Summary: The study aimed to assess visual outcomes and prevalence of amblyogenic risk factors in children with Apert, Crouzon, Pfeiffer and Saethre-Chotzen syndromes. The majority of patients achieved best-corrected visual acuity >= 6/12 in their better eye despite a high prevalence of amblyogenic factors. Optic neuropathy and nystagmus had significant impact on vision, while Visual Evoked Potentials (VEPs) were helpful in assessing overall visual function.

Summary: The study analyzed giant amplitude pattern reversal VEPs in 2750 children aged 16 years and under, revealing associations between this phenomenon and a risk of raised intracranial pressure, with conditions such as craniosynostosis and idiopathic intracranial hypertension commonly identified. Structural associations included optic disc measurements and neuro-radiological findings, while raised ICP was confirmed in some cases through gold standard measurements.

Summary: This study evaluated the diagnostic accuracy of fundoscopy and visual evoked potentials (VEPs) in detecting intracranial hypertension (IH) in patients with craniosynostosis undergoing spring-assisted posterior vault expansion (sPVE). The results showed that fundoscopy reliably indicated IH, while VEP testing boosted sensitivity at the expense of specificity.
