Multispectral scanning time-resolved fluorescence spectroscopy (TRFS) technique for intravascular diagnosis

Biomedical Optics Express, 2012
This study describes a scanning time-resolved fluorescence spectroscopy (TRFS) system designed to continuously acquire fluorescence emission and to reconstruct fluorescence lifetime images (FLIM) from a luminal surface by using a catheter-based optical ...

Head‐to‐Head Comparison of Four Ultrasound Elastography Techniques in Detecting Advanced Fibrosis

Portal Hypertension &Cirrhosis, EarlyView.
Elastography is an important noninvasive method for diagnosing advanced fibrosis (AF); however, evidence remains insufficient, particularly regarding acoustic radiation force impulse (ARFI) techniques. This prospective mulitcenter study concludes that vibration controlled transient elastography (VCTE) demonstrates superior diagnostic performance to ...

Endogenous tRNA-derived fragments suppress breast cancer progression via YBX1 displacement

Cell, 2015
SUMMARY Upon exposure to stress, tRNAs are enzymatically cleaved, yielding distinct classes of tRNA-derived fragments (tRFs). We identify a novel class of tRFs derived from tRNAGlu, tRNAAsp, tRNAGly, and tRNATyr that, upon induction, suppress the ...

Further development of adaptive parameter tuning in the numerical weather prediction models of Deutscher Wetterdienst

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The introduction of adaptive parameter tuning in the numerical weather prediction models of DWD in 2022 substantially improved the forecast quality of near‐surface variables like 2‐m temperature and 2‐m humidity. Since 2023, refinements and extensions, primarily affecting the surface evaporation and its diurnal cycle, have led to further advances ...

Investigation of the association of tRNA-derived fragments (tRF-17-79MP9PP and tRF-18- 79MP9P04) with prostate cancer

Molecular Biology Reports
Abstract Introduction: This study explores the relationship between the expression levels of two tRNA-derived fragments, tRF-17-79MP9PP and tRF-18-79MP9P04, and the pathophysiology of prostate cancer (PCa). Material and methods A total of 40 patients were included: 8 with benign prostatic hyperplasia (BPH) and 32 with varying PCa grades.

Microplastics and the Endocrine–Metabolic Interface: Novel Diagnostic Tools Targeting Thyroid–Adipose Axis

Environmental Toxicology, EarlyView.
ABSTRACT Microplastics (MPs) have been identified as major environmental contaminants that can affect organisms directly and act as carriers of particles and chemical additives, thereby aggravating endocrine networks that coordinate metabolic homeostasis.

TRF Test in Patients with Hypothalamic-Pituitary Disorders

Endocrinologia Japonica, 1973
TRF test with 50-100μg of synthetic TRF was performed in 57 patients with hypothalamic-pituitary disorders. According to the degree and the pattern of TSH response, they were classified as an absent, subnormal, normal or supernormal response and/or delayed pattern of TSH response.

From Consumer Plastics to Aquatic Toxicants: Oxidative and Endocrine Effects of Microplastics on Fathead Minnow (Pimephales promelas) Larvae

Environmental Toxicology, EarlyView.
ABSTRACT Secondary microplastics (MPs) from single‐use consumer products are rapidly becoming one of the most persistent and widespread pollutants of our time. Freshwater systems act as early sinks for MPs where fragmentation and additive leaching expose aquatic life to a broad spectrum of toxic compounds.

Validation of tRNA-derived fragments as diagnostic biomarkers in suspected acute stroke; limitations in analysis and quantification methods

Molecular Therapy: Nucleic Acids
In acute stroke, timely diagnosis is essential to prevent extensive neuronal damage and improve patient outcomes. However, differentiating between ischemic stroke, intracerebral hemorrhage, and stroke mimics remains challenging.
