Integral-Omics: Serial Extraction and Profiling of Metabolome, Lipidome, Genome, Transcriptome, Whole Proteome and Phosphoproteome Using Biopsy Tissue.

The integrative multiomics characterization of minute amounts of clinical tissue specimens has become increasingly important. Here, we present an approach called Integral-Omics, which enables sequential extraction of metabolites, lipids, genomic DNA, total RNA, proteins, and phosphopeptides from a single biopsy-level tissue specimen. We benchmarked this method with various samples, applied the workflow to perform multiomics profiling of tissues from six patients with colorectal cancer, and found that tumor tissues exhibited suppressed ferroptosis pathways at multiomics levels.

Challenges and New Directions in Therapeutic Cancer Vaccine Development.

Tumor vaccine is a promising immunotherapy for solid tumors.

However, tumor-induced immune suppression and immune resistance pose challenges to achieving this goal.

SPI1 facilitates microfracture-mediated cartilage regeneration in the elderly by enhancing bone marrow stromal cells ctemness.

Bone marrow stimulation treatment by bone marrow stromal cells (BMSCs) released from the bone medullary cavity and differentiated into cartilage via microfracture surgery is a frequently employed technique for treating articular cartilage injuries, yet the treatment presents a main drawback of poor cartilage regeneration in the elderly. Prior research indicated that aging could decrease the stemness capacity of BMSCs, thus we made a hypothesis that increasing old BMSCs (OBMSCs) stemness might improve the results of microfracture in the elderly. First, we investigated the correlation between microfracture outcomes and BMSCs stemness using clinical data and animal experiments.

Natural ingredients in the regulation of abnormal lipid peroxidation: a potential therapy for pulmonary diseases.

Pulmonary diseases are a major category of diseases that pose a threat to human health. The most common drugs currently used to treat lung diseases are still chemical drugs, but this may lead to drug resistance and damage to healthy organs in the body. Therefore, developing new drugs is an urgent task.

Folate-targeted nanoparticles for glutamine metabolism inhibition enhance anti-tumor immunity and suppress tumor growth in ovarian cancer.

Ovarian cancer (OC) is a highly malignant gynecological tumor, and its effective treatment is frequently impeded by drug resistance and recurrent tumor growth. The reprogramming of glutamine metabolism in ovarian cancer is closely associated with tumor progression and the immunosuppressive tumor microenvironment. Recently, targeting metabolic reprogramming has emerged as a promising approach for cancer therapy.

CpG hypomethylation at proximal promoter and 5'UTR along with IL6 signaling loop associates with MYD88 upregulation in epithelial ovarian cancer.

MYD88 is an IL-6 primary response gene and, its upregulation of expression has been shown to be a poor prognostic factor in epithelial ovarian cancer (EOC). We investigated the effects of CpG methylation at the proximal promoter/5'UTR and IL-6/SP1/IRF1 signaling on upregulation of MYD88 and prognosis in EOC. We assessed CpG methylation at the proximal promoter/5'UTR of MYD88 using bisulfite sequencing/PCR in 103 EOC patients, 28 normal ovarian tissues and two EOC cell lines with differential expression of MYD88 and identified the impact of the level of CpG methylation on MYD88 upregulation by SP1/IRF1 with knockdown or blockade of IL-6.

Effective Bone Tissue Fabrication Using 3D-Printed Citrate-Based Nanocomposite Scaffolds Laden with BMP9-Stimulated Human Urine Stem Cells.

Effective repair of large bone defects through bone tissue engineering (BTE) remains an unmet clinical challenge. Successful BTE requires optimal and synergistic interactions among biocompatible scaffolds, osteogenic factors, and osteoprogenitors to form a highly vascularized microenvironment for bone regeneration and osseointegration. We sought to develop a highly effective BTE system by using 3D printed citrate-based mPOC/hydroxyapatite (HA) composites laden with BMP9-stimulated human urine stem cells (USCs).

Self-Wrinkling-Induced Mechanically Adaptive Patterned Surface of Photocuring Coating for Abrasion Resistance.

Providing mechanically adaptive performance to surfaces is significant in preserving materials from damage in variable environments, however, it has rarely been studied. Inspired by the mechanically adaptive behaviors of the surface microstructure on the carapace of desert scorpions and bark of desert tamarisks, a self-wrinkled mechanically adaptive patterned surface (SWMAPS) using one-step UV-curing and self-wrinkling technique is reported. Because of the fluorinated polyurethane photo-initiator formed by self-assembly at the top surface, UV-induced photo-crosslinking can spontaneously generate a gradient-crosslinked structure and wrinkled patterns with different morphology.

Comparative analysis of niche adaptation strategies of AOA, AOB, and comammox along a gate-controlled river-estuary continuum.

Ammonia oxidizers are key players in the biogeochemical nitrogen cycle. However, in critical ecological zones such as estuaries, especially those affected by widespread anthropogenic dam control, our understanding of their occurrence, ecological performance, and survival strategies remains elusive. Here, we sampled sediments along the Haihe River-Estuary continuum in China, controlled by the Haihe Tidal Gate, and employed a combination of biochemical and metagenomic approaches to investigate the abundance, activity, and composition of ammonia-oxidizing archaea (AOA), ammonia-oxidizing bacteria (AOB), and complete ammonia oxidizers (comammox).

Molecular profile of adult primary leptomeningeal gliomatosis aligns with glioblastoma, IDH-wildtype.

Adult primary leptomeningeal gliomatosis (PLG) is a rare, rapidly progressive and fatal disease characterized by prominent leptomeningeal infiltration by a glial tumor without an identifiable parenchymal mass. The molecular profile of adult PLG has not been well-characterized. We report the clinical, pathological, and molecular findings of six adult PLG patients (five males and one female), median age 58 years.

Peroxiredoxin 4 Ameliorates T-2 Toxin-Induced Growth Retardation in GH3 Cells by Inhibiting Oxidative Stress and Apoptosis.

T-2 toxin, a highly toxic type A trichothecene, is a secondary fungal metabolite produced by various Fusarium species. The consumption of food and feed contaminated with T-2 toxin is a major factor contributing to growth retardation, posing significant risks to both human and animal health. However, the specific targets and mechanisms that mitigate T-2 toxin-induced growth retardation remain unclear.

Investigating autonomic dysfunction in post-COVID-19 syndrome from skin to brain: A case-control study using EMG-SSR and fNIRS.

Background: Autonomic dysfunction is a well-recognized complication associated with post-COVID-19 syndrome (PCS). ANS maladaptation could underlie a potential pathogenetic mechanism of PCS, contributing to PCS symptoms. However, there remains an ongoing debate regarding whether autonomic and neuropathic symptoms observed in PCS patients are indicative of central or peripheral ANS pathology.

A self-learning magnetic Hopfield neural network with intrinsic gradient descent adaption.

Physical neural networks (PNN) using physical materials and devices to mimic synapses and neurons offer an energy-efficient way to implement artificial neural networks. Yet, training PNN is difficult and heavily relies on external computing resources. An emerging concept to solve this issue is called physical self-learning that uses intrinsic physical parameters as trainable weights.

A library of lineage-specific driver lines connects developing neuronal circuits to behavior in the Ventral Nerve Cord.

Understanding the developmental trajectories of neuronal lineages is crucial for elucidating how they are assembled into functional neural networks. Studies investigating the nervous system development in model animals have focused only on a few regions of the Central Nervous System due to the limited availability of genetic drivers to target these regions throughout development and adult life. This hindered our understanding of how distinct neuronal lineages come together to form neuronal circuits during development.

Carbonized wood loading sustainable tannin used as free-standing electrodes for assembling heavy metal-free supercapacitors.

The design of heavy metal-free thick supercapacitor electrodes with excellent energy storage performance through a novel and effective strategy represents an attractive yet challenging area of research. In this study, a sustainable redox-active tannic acid (TA) is loaded on the carbonized wood (CW) collector to construct a low-curvature, high-capacity, heavy metal-free supercapacitor electrode. The uniform loading of TA on the surface of the CW cell wall is achieved through the combined action of mutually stable hydrogen bonding and π-π interactions, which constructs a fast electron transport channel in the collector.

However, the potential application of CAR-T cells secreted antibody fragment simultaneously in solid tumor is rarely explored. In this study, we searched bioinformatic databases and investigated the characteristics of CD47 in solid tumors.

An improved sample selection framework for learning with noisy labels.

Deep neural networks have powerful memory capabilities, yet they frequently suffer from overfitting to noisy labels, leading to a decline in classification and generalization performance. To address this issue, sample selection methods that filter out potentially clean labels have been proposed. However, there is a significant gap in size between the filtered, possibly clean subset and the unlabeled subset, which becomes particularly pronounced at high-noise rates.

Cyclic natural product oligomers: diversity and (bio)synthesis of macrocycles.

Cyclic compounds are generally preferred over linear compounds for functional studies due to their enhanced bioavailability, stability towards metabolic degradation, and selective receptor binding. This has led to a need for effective cyclization strategies for compound synthesis and hence increased interest in macrocyclization mediated by thioesterase (TE) domains, which naturally boost the chemical diversity and bioactivities of cyclic natural products. Many non-ribosomal peptide synthetase (NRPS) and polyketide synthase (PKS) derived natural products are assembled to form cyclodimeric compounds, with these molecules possessing diverse structures and biological activities.
