We present a curve fitting method for measuring the spectral distribution of femtosecond laser pulses with Young's double-pair interference. The method is applicable to cancel the influence of the mutual coherent portion in the spectrum measurement.

Intranasal administration of oxytocin is emerging as a potential pharmacological option for mitigating social difficulties and regulating stress in autism spectrum disorder. However, initial single-dose and multiple-dose trials showed mixed results, with some demonstrating improvements in social and repetitive behavior and others showing no benefit over placebo. This perspective aims to elucidate factors contributing to this variability and to highlight pitfalls and opportunities in the field.

Dengue fever, caused by the dengue virus (DENV), poses a significant global health challenge, particularly in tropical and subtropical regions. Recent increases in indigenous DENV cases in Europe are concerning, reflecting rising incidence linked to climate change and the spread of mosquitoes. These vectors thrive under environmental conditions like temperature and humidity, which are increasingly influenced by climate change.

Background: The metabolism of plasma amino acid (AA) in children with autism spectrum disorder (ASD) has been extensively investigated, yielding inconclusive results. This study aims to characterize the metabolic alterations in AA profiles among early-diagnosed children with ASD and compare the findings with those from non-ASD children.
Methods: We analyzed plasma AA profiles, measured by ion exchange chromatography, from 1242 ASD children (median age = 4 years; 81% male).

(1) : Targeted alpha therapy is an emerging field in nuclear medicine driven by two advantages: overcoming resistance in cancer-suffering patients to beta therapies and the practical application of lower activities of Pb- and Ac-labelled peptides to achieve the same doses compared to beta therapy due to the highly cytotoxic nature of alpha particles. However, quality control of the Pb/Ac-radiopharmaceuticals remains a challenge due to the low activity levels used for therapy (100 kBq/kg) and the formation of several free daughter nuclides immediately after the formulation of patient doses; (2) : The routine alpha detection on thin-layer chromatograms (TLC) of Pb- and Ac-labelled peptides using a MiniScanPRO+ scanner combined with an alpha detector head was compared with detection using an AR-2000 scanner equipped with an open proportional counter tube. Measurement time, resolution and validity were compared for both scanners; (3) : For Ac, the quality control values of the radiochemical purity (RCP) were within the acceptance criteria 2 h after TLC development, regardless of when the TLC probe was taken.

The design of optical sensors aims at providing, among other things, the highest precision in the determination of the target measurand. Many sensor systems rely on a spectral transducer to map changes in the measurand into spectral shifts of a resonance peak in the reflection or transmission spectrum, which is measured by a readout device (e.g.
