Plasmonics‐Enhanced Characterization of Cervid PrP (87–114) Fragment Aggregates in Solution

Journal of Biophotonics, EarlyView.
Multimodal nanophotonics platform combining plasmon‐enhanced imaging, label‐free SERS, and optical staining reveals new insights into the aggregation of the cervid PrP (87–114) fragment, an amyloidogenic sequence linked to chronic wasting disease susceptibility.

Fourier ring correlation simplifies image restoration in fluorescence microscopy

Nature Communications, 2019
Fourier ring correlation (FRC) analysis is commonly used in fluorescence microscopy to measure effective image resolution. Here, the authors demonstrate that FRC can also be leveraged in blind image restoration methods, such as image deconvolution.

Preoperative VEGFR‐TKI Plus ICI Therapy Facilitates 3D‐Guided Cytoreductive Nephron‐Sparing Surgical Feasibility and Immune Remodeling in Advanced Renal Cell Carcinoma

Med Research, EarlyView.
Preoperative VEGFR‐TKI plus ICI therapy in advanced ccRCC normalizes tumor vasculature, enhances CD8⁺ T/B cell infiltration, and promotes TLS maturation, leading to profound tumor microenvironment remodeling. These immunologic changes improve the feasibility of 3D reconstruction‐guided robotic cytoreductive nephron‐sparing surgery, resulting in reduced

Explicit Deconvolution of Well Test Data Dominated by Wellbore Storage

Abstract and Applied Analysis, 2014
This paper addresses some methods for interpretation of oil and gas well test data distorted by wellbore storage effects. Using these techniques, we can deconvolve pressure and rate data from drawdown and buildup tests dominated by wellbore storage. Some

Domination Versus Sisterhoods in the Blood Microbiota of Migrating Birds: Patterns of Within‐ and Between‐Individual Blood Parasite Diversity Revealed Through Metabarcoding

Integrative Zoology, EarlyView.
Avian haemosporidian blood parasites are typically identified through Sanger sequencing of a partial cytochrome b fragment, the MalAvi barcoding region. Next‐generation sequencing is seldom used for avian blood parasite identification; this study demonstrates a higher detection rate of co‐infections via metabarcoding and its possible implications ...

A new image deconvolution method with fractional regularisation

Journal of Algorithms & Computational Technology, 2016
Image deconvolution is an important pre-processing step in image analysis which may be combined with denoising, also an important image restoration technique, and prepares the image to facilitate diagnosis in the case of medical images and further ...

A quad‐cistronic fluorescent biosensor system for real‐time detection of subcellular Ca2+ signals

British Journal of Pharmacology, EarlyView.
Background and Purpose The calcium ion (Ca2+) is a versatile cellular messenger regulating a variety of biological processes. Compounds modulating subcellular Ca2+ signals hold substantial pharmacological potential. Advances in fluorescent biosensors have revolutionised Ca2+ imaging.

Tumor‐Associated Macrophage‐Derived CXCL1 Promotes Endometrial Cancer Progression Through the CXCR2/NF‐κB Pathway

Cancer Science, EarlyView.
CXCL1 secreted by M2 macrophages induced EMT of EC cells through the CXCR2/NF‐κB pathway; CXCR2 expression was predominantly observed in the epithelial compartment, whereas CXCL1 expression was primarily localized in the stromal region; Neutralization of M2 macrophage‐secreted CXCL1 and inhibiting the NF‐κB pathway can inhibit EC progression in vivo ...
