Theoretical analysis and simulation of a high SNR and real-time MPMG-based computational spectrometer.

Achieving a balance between signal-to-noise ratio (SNR) and real-time performance in infrared (IR) spectral detection of weak and moving targets is a significant challenge. Here, we propose a long-wave infrared (LWIR) computational spectrometer (MPMGFTS) based on a multi-depth phase modulation grating (MPMG). MPMG functions as the core component of the MPMGFTS.

Advanced multispectral thermometry method based on an improved light spectrum optimizer for reliable temperature and emissivity measurement.

The multispectral thermometry method offers non-contact temperature and emissivity measurement with significant advantages over traditional thermometry. However, current multispectral techniques encounter challenges in processing multispectral data, especially when executing temperature and emissivity inversions without the emissivity-wavelength relationship and achieving real-time measurements from data with numerous spectral channels. These limitations hinder the practical application of multispectral measurement techniques.

Aberrant interhemispheric resting state functional connectivity and corpus callosum microstructure in acute carbon monoxide poisoning.

Acute carbon monoxide poisoning (ACOP) is a significant contributor to acute poisoning incidents worldwide, with numerous patients suffering from cognitive impairment. Growing evidence indicates that patients with ACOP exhibit both disrupted functional connectivity and corpus callosum (CC) degeneration. Nevertheless, how interhemispheric connectivity is altered in ACOP and how such alterations relate to cognitive deficits remain largely unexplored.

Periostin-mediated activation of NF-κB signaling promotes tumor progression and chemoresistance in glioblastoma.

Glioblastoma (GBM) is the most aggressive form of diffuse glioma, characterized by high lethality. Temozolomide (TMZ)-based chemotherapy is a standard treatment for GBM, but development of chemoresistance poses a significant therapeutic challenge. Despite advances in understanding GBM biology, the mechanisms driving TMZ resistance remain unclear.

Geometric deep learning with adaptive full-band spatial diffusion for accurate, efficient, and robust cortical parcellation.

Cortical parcellation delineates the cerebral cortex into distinct regions according to their distinctiveness in anatomy and/or function, which is a fundamental preprocess in brain cortex analysis and can influence the accuracy and specificity of subsequent neuroscientific research and clinical diagnosis. Conventional methods for cortical parcellation involve spherical mapping and multiple morphological feature computation, which are time-consuming and prone to error due to the spherical mapping process. Recent geometric learning approaches have attempted to automate this process by replacing the registration-based parcellation with deep learning-based methods.

Correction of Non-Uniform Rotational Distortion in the Proximally Controlled Endoscopic OCTA.

Endoscopic Optical Coherence Tomography (OCT) can provide high-resolution cross-sectional images for internal organ tissues. Combining the endoscopic imaging with Optical Coherence Tomography Angiography (OCTA), information of blood vessels in superficial lumen tissues is expected to be acquired. However, in endoscopic OCT systems using proximal scanning probes, performance of OCTA encounters significant challenges due to non-uniform rotational distortion (NURD) caused by the non-constant rotation of the distal imaging unit.

Contrast-enhanced near-infrared photoacoustic microscopy and optical coherence tomography imaging of rat fundus.

In this paper, we design a multimodal visible/near-infrared photoacoustic microscopy and optical coherence tomography (VIS/NIR-PAM-OCT) system for imaging both retina and retinal pigment epithelium (RPE)/choroid complex layer. F127 and DSPE-PEG-cRGD encapsulated IR-1048 nanoparticles (FINPs) exhibiting absorption peak up to 1,064 nm were utilized as contrast agents to enhance NIR-PAM for imaging of fundus tissues. The fundus structure and vessels are clearly visualized by the multimodal imaging, and their parameters were quantitatively analyzed.

Key point of desert riparian forest development in the arid area: The response of phreatic water table depth to ecological water supply.

Desert riparian forest vegetation maintains the fragile balance of ecosystems in extreme arid areas. Raising the phreatic water table through efficient ecological water supply is the key to the desert riparian forests in extreme arid areas. The main objective of this study is to explore an innovative framework in which the response of phreatic water table depth (PWTD) to ecological water supply flow (EWSF) can be effectively reflected.

Endoscopic OCTA in continuous rotation and retraction scheme using a proximal scanning catheter.

Endoscopic optical coherence tomography (OCT) is widely used in the detection of morphological alterations in luminal organs, which provides high-resolution, three-dimensional (3D) images of internal tissues. In most cases, lesions are revealed early by microvascular pathological changes in cavity tissues. There is a significant demand for the performance of endoscopic OCT angiography (OCTA) to visualize the superficial capillaries.

12-HETE/GPR31 induces endothelial dysfunction in diabetic retinopathy.

12-hydroxyeicosatetraenoic acid (12-HETE), a major metabolite of arachidonic acid, is converted by 12/15-lipoxygenase and implicated in diabetic retinopathy (DR). Our previous study demonstrated a positive correlation between 12-HETE and the prevalence of DR. However, reasons for the increased production of 12-HETE are unclear, and the underlying mechanisms through which 12-HETE promotes DR are unknown.

The main object of this study was to allocate and schedule water resources to regulate the PWTD and satisfy agricultural water demand.

A Multi-Center, Multi-Parametric MRI Dataset of Primary and Secondary Brain Tumors.

Brain metastases (BMs) and high-grade gliomas (HGGs) are the most common and aggressive types of malignant brain tumors in adults, with often poor prognosis and short survival. As their clinical symptoms and image appearances on conventional magnetic resonance imaging (MRI) can be astonishingly similar, their accurate differentiation based solely on clinical and radiological information can be very challenging, particularly for "cancer of unknown primary", where no systemic malignancy is known or found. Non-invasive multiparametric MRI and radiomics offer the potential to identify these distinct biological properties, aiding in the characterization and differentiation of HGGs and BMs.

In all, 770 proteins and 2,914 peptide segments were identified. Statistical analysis showed significant differences in the relative abundances of the 74 proteins among sheep, goat, and cow milk.

Dynamic changes of gut microbiota in mouse models of metabolic dysfunction-associated steatohepatitis and its transition to hepatocellular carcinoma.

Dysbiosis of gut microbiota may account for pathobiology in simple fatty liver (SFL), metabolic dysfunction-associated steatohepatitis (MASH), fibrotic progression, and transformation to MASH-associated hepatocellular carcinoma (MASH-HCC). The aim of the present study is to investigate gut dysbiosis in this progression. Fecal microbial rRNA-16S sequencing, absolute quantification, histopathologic, and biochemical tests were performed in mice fed high fat/calorie diet plus high fructose and glucose in drinking water (HFCD-HF/G) or control diet (CD) for 2, 16 weeks, or 14 months.
