Automated segmentation of deep brain structures from Inversion-Recovery MRI.

Methods for the automated segmentation of brain structures are a major subject of medical research. The small structures of the deep brain have received scant attention, notably for lack of manual delineations by medical experts. In this study, we assessed an automated segmentation of a novel clinical dataset containing White Matter Attenuated Inversion-Recovery (WAIR) MRI images and five manually segmented structures (substantia nigra (SN), subthalamic nucleus (STN), red nucleus (RN), mammillary body (MB) and mammillothalamic fascicle (MT-fa)) in 53 patients with severe Parkinson's disease.

Cardioprotective potential of tectochrysin against vanadium induced heart damage via regulating NLRP3, JAK1/STAT3 and NF-κB pathway.

Aim: The current study was planned to assess the cardioprotective potential of TEC against VAN induced cardiotoxicity in rats via regulating biochemical, and histological profile.

Vanin-1-Activated Fluorescent Probe for Real-Time Imaging of Inflammatory Responses Across Multiple Tissue Types.

Vanin-1 is a pantetheine hydrolase that plays a key role in inflammatory diseases. Effective tools for noninvasive, real-time monitoring of Vanin-1 are lacking, largely due to background fluorescence interference in existing probes. To address this issue, we developed a dual-modal fluorescent and colorimetric probe, MB-Van1, to detect Vanin-1 with high sensitivity and selectivity.

Let-7b-5p sensitizes breast cancer cells to doxorubicin through Aurora Kinase B.

It has been proven that deregulated miRNAs may play an essential role in the progression of breast cancer.

A BODIPY-Containing Covalent Organic Framework as a Highly Porous Photosensitizer for Environmental Remediation and Pollutants Adsorption.

The direct incorporation of borondipyrromethene (BODIPY) subunits into the structural backbone of covalent organic frameworks (COFs) gives facile access to porous photosensitizers but is still a challenging task. Here, we introduce β‑ketoenamine-linked BDP‑TFP‑COF, which crystallizes in AA‑stacking mode with hcb topology. A comprehensive characterization reveals high crystallinity and enhanced stability in a variety of solvents, excellent mesoporosity (SABET = 1042 m2 g-1), broad light absorption in the visible region, and red emission upon the exfoliation of few-layer COF nanosheets.

A high-throughput platform for single-molecule tracking identifies drug interaction and cellular mechanisms.

The regulation of cell physiology depends largely upon interactions of functionally distinct proteins and cellular components. These interactions may be transient or long-lived, but often affect protein motion. Measurement of protein dynamics within a cellular environment, particularly while perturbing protein function with small molecules, may enable dissection of key interactions and facilitate drug discovery; however, current approaches are limited by throughput with respect to data acquisition and analysis.

Functionalized Substrates for Reduced Nonradiative Recombination in Metal-Halide Perovskites.

Reducing nonradiative recombination is crucial for minimizing voltage losses in metal-halide perovskite solar cells and achieving high power conversion efficiencies. Photoluminescence spectroscopy on complete or partial perovskite solar cell stacks is often used to quantify and disentangle bulk and interface contributions to nonradiative losses. Accurately determining the intrinsic loss in a perovskite layer is key to analyzing the origins of nonradiative recombination and developing defect engineering strategies.
