Sub-ppb Methane Detection via EMD–Wavelet Adaptive Thresholding in Wavelength Modulation TDLAS: A Hybrid Denoising Approach for Trace Gas Sensing

Sensors
Wavelength modulation-tunable diode laser absorption spectroscopy (WM-TDLAS) is a critical tool for gas detection. However, noise in second harmonic signals degrades detection performance.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Pitfalls of UBT, SAT, and Nested PCR Reliability for Diagnosing Helicobacter pylori

LabMed
Helicobacter pylori is the leading cause of chronic gastrointestinal tract diseases, with a worldwide prevalence of around 50%. For identification in medical practice, non-invasive methods such as the immunochromatographic test for antigen in stool (SAT)

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

An All-solid-state Cd2+-selective electrode with a low detection limit

, 2011
A new all-solid-state Cd2+-selective electrode with a low detection limit was prepared by using conjugated thiophene oligomer alpha-sexithiophene (alpha-6T) as solid contact deposited between an ionophore-doped poly(vinyl chloride) membrane and a gold ...

Rapid and Low-Cost N-Doped Carbon Dots Synthesis Based on Orange Peels for Highly Sensitive Detection of Ferric and Mercury Ions

Chemosensors
Using orange peels as a biowaste, fluorescent N-CDs were prepared simply and rapidly through a one-step microwave-assisted method and urea as a nitrogen source.

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Improving detection limit of non-dispersive infrared gas sensor with high precision by matched filtering

International Journal of Optomechatronics
Non-dispersive infrared (NDIR) gas sensors have the disadvantage of high limit of detection (LOD), and the signal-to-noise ratio (SNR) has a significant impact on LOD.
