Systematic inference of super-resolution cell spatial profiles from histology images.

Inferring cell spatial profiles from histology images is critical for cancer diagnosis and treatment in clinical settings. In this study, we report a weakly-supervised deep-learning method, HistoCell, to directly infer super-resolution cell spatial profiles consisting of cell types, cell states and their spatial network from histology images at the single-nucleus-level. Benchmark analysis demonstrates that HistoCell robustly achieves state-of-the-art performance in terms of cell type/states prediction solely from histology images across multiple cancer tissues.

Decrease of NAD Inhibits the Apoptosis of OLP T Cells via Inducing Mitochondrial Fission.

Purpose: Oral lichen planus (OLP) is a chronic, immune-mediated inflammatory disease involving T cells. Mitochondrial fission plays a crucial role in T cell fate through structural remodeling. Nicotinamide adenine dinucleotide (NAD) regulates mitochondrial remodeling and function.

Action potential-independent spontaneous microdomain Ca transients-mediated continuous neurotransmission regulates hyperalgesia.

Neurotransmitters and neuromodulators can be released via either action potential (AP)-evoked transient or AP-independent continuous neurotransmission. The elevated AP-evoked neurotransmission in the primary sensory neurons plays crucial roles in hyperalgesia. However, whether and how the AP-independent continuous neurotransmission contributes to hyperalgesia remains largely unknown.

Associations of traditional healthy lifestyle and sleep quality with metabolic dysfunction-associated fatty liver disease: two population-based studies.

Aims: To examine whether an extended lifestyle metrics incorporating sleep quality improves risk stratification for metabolic dysfunction-associated fatty liver disease (MAFLD), at-risk metabolic dysfunction-associated steatohepatitis (MASH) and significant fibrosis.

Methods: A total of 5011 participants with abdominal ultrasound from Imaging sub-cohort of South China Cohort (ISSCC) and 3672 participants underwent vibration controlled transient elastography from US National Health and Nutrition Examination Survey (US NHANES) were included. Liver Essential 5 was constructed by incorporating sleep quality into traditional healthy lifestyles (HLS).

Regulatory role of primary cilia in oral and maxillofacial development and disease.

Primary cilia have versatile functions, such as receiving signals from the extracellular microenvironment, mediating signaling transduction, and transporting ciliary substances, in tissue and organ development and clinical disease pathogenesis. During early development (embryos within 10 weeks) in the oral and maxillofacial region, defects in the structure and function of primary cilia can result in severe craniofacial malformations. For example, mice with mutations in the cilia-related genes Kif3a and IFT88 exhibit midline expansion and cleft lip/palate, which occur due to abnormalities in the fusion of the single frontonasal prominence and maxillary prominences.

Stronger stimulus triggers synaptic transmission faster through earlier started action potential.

Synaptic transmission plays an important and time-sensitive role in the nervous system. Although the amplitude of neurotransmission is positively related to the intensity of external stimulus, whether stronger stimulus could trigger synaptic transmission faster remains unsolved. Our present work in the primary sensory system shows that besides the known effect of larger amplitude, stronger stimulus triggers the synaptic transmission faster, which is regulated by the earlier started action potential (AP), independent of the AP's amplitude.

Kinect-based objective assessment of the acute levodopa challenge test in parkinsonism: a feasibility study.

Introduction: The acute levodopa challenge test (ALCT) is an important and valuable examination but there are still some shortcomings with it. We aimed to objectively assess ALCT based on a depth camera and filter out the best indicators.

Methods: Fifty-nine individuals with parkinsonism completed ALCT and the improvement rate (IR, which indicates the change in value before and after levodopa administration) of the Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale part III (MDS-UPDRS III) was calculated.

A digital nanoplasmonic microarray immunosensor for multiplexed cytokine monitoring during CAR T-cell therapy from a leukemia tumor microenvironment model.

The release of cytokines by chimeric antigen receptor (CAR) T-cells and tumor resident immune cells defines a significant part of CAR T-cell functional activity and patient immune responses during CAR T-cell therapy. However, few studies have so far precisely characterized the cytokine secretion dynamics in the tumor niche during CAR T-cell therapy, which requires multiplexed, and timely biosensing platforms and integration with biomimetic tumor microenvironment. Herein, we implemented a digital nanoplasmonic microarray immunosensor with a microfluidic biomimetic Leukemia-on-a-Chip model to monitor cytokine secretion dynamics during CD19 CAR T-cell therapy against precursor B-cell acute lymphocytic leukemia (B-ALL).

Computational model of CAR T-cell immunotherapy dissects and predicts leukemia patient responses at remission, resistance, and relapse.

Background: Adaptive CD19-targeted chimeric antigen receptor (CAR) T-cell transfer has become a promising treatment for leukemia. Although patient responses vary across different clinical trials, reliable methods to dissect and predict patient responses to novel therapies are currently lacking. Recently, the depiction of patient responses has been achieved using in silico computational models, with prediction application being limited.

A Computational Model of Cytokine Release Syndrome during CAR T-cell Therapy.

Cytokine release syndrome (CRS) is a lethal adverse event in chimeric antigen receptor (CAR) T-cell therapy, hindering this promising therapy for cancers, such as B-cell acute lymphoblastic leukemia (B-ALL). Clinical management of CRS requires a better understanding of its underlying mechanisms. In this study, a computational model of CRS during CAR T-cell therapy is built to depict how the cellular interactions among CAR T-cells, B-ALL cells, and bystander monocytes, as well as the accompanying molecular interactions among various inflammatory cytokines, influence the severity of CRS.

Enhanced Label-Free Nanoplasmonic Cytokine Detection in SARS-CoV-2 Induced Inflammation Using Rationally Designed Peptide Aptamer.

Rapid and precise serum cytokine quantification provides immense clinical significance in monitoring the immune status of patients in rapidly evolving infectious/inflammatory disorders, examplified by the ongoing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. However, real-time information on predictive cytokine biomarkers to guide targetable immune pathways in pathogenic inflammation is critically lacking, because of the insufficient detection range and detection limit in current label-free cytokine immunoassays. In this work, we report a highly sensitive localized surface plasmon resonance imaging (LSPRi) immunoassay for label-free Interleukin 6 (IL-6) detection utilizing rationally designed peptide aptamers as the capture interface.

Multi-threshold splitting tree algorithm to reduce the number of filters in programmable hyperspectral imaging for fast multi-target classification.

Programmable hyperspectral imaging is a promising and efficient technique for fast target classification by coding hyperspectral post-processing algorithms as spectral transmittances, which enables such post-processing to be directly performed by special optical dispersive element during the process of optical imaging. Compared with conventional hyperspectral imaging and post-processing techniques, it shows significant advantages of fast image acquisition, post-processing free, and a much lower load of data transmission and storage. However, when multi-target classification tasks are encountered, the speed would decrease seriously due to the requirement of a large number of filters.
