SPP1+ macrophages promote head and neck squamous cell carcinoma progression by secreting TNF-α and IL-1β.

Background: Head and neck squamous cell carcinoma (HNSCC) is a very aggressive disease characterized by a heterogeneous tumor immune microenvironment (TIME). Tumor-associated macrophages (TAMs) constitute the major innate immune population in the TIME where they facilitate crucial regulatory processes that participate in malignant tumor progression. SPP1 + macrophages (SPP1 + Macs) are found in many cancers, but their effects on HNSCC remain unknown.

Chronic intermittent hypobaric hypoxia alleviates early-stage posttraumatic osteoarthritis via NF-κB/Nrf2 pathway in mice.

Background: Posttraumatic osteoarthritis (PTOA) is directly associated with early acute articular cartilage injury. Inhibition of cartilage destruction immediately following joint damage can effectively slow or prevent PTOA progression. Therefore, we sought to determine intervention targets and therapeutic strategies in the acute stage of cartilage injury.

Investigating the inflammatory mechanism of notoginsenoside R1 in Diabetic nephropathy via ITGB8 based on network pharmacology and experimental validation.

Background: Diabetes often causes diabetic nephropathy (DN), a serious long-term complication. It is characterized by chronic proteinuria, hypertension, and kidney function decline, can progress to end-stage renal disease, lowering patients' quality of life and lifespan. Inflammation and apoptosis are key to DN development.

Hearing modulation affects Alzheimer's disease progression linked to brain inflammation: a study in mouse models.

Background: Recent studies have identified hearing loss (HL) as a primary risk factor for Alzheimer's disease (AD) onset. However, the mechanisms linking HL to AD are not fully understood. This study explored the effects of drug-induced hearing loss (DIHL) on the expression of proteins associated with AD progression in mouse models.

A novel herpesvirus in blue penguins putatively associated with myocardial degeneration and necrosis.

We identified a novel herpesvirus in 2 deceased captive blue penguins (). Moderate-to-severe myocardiocyte atrophy and necrosis, and eosinophilic intranuclear inclusion bodies (INIBs), were seen in myocardiocytes in one bird; reticuloendothelial (RE) cell INIBs and multifocal RE cell necrosis were seen in both birds. The histologic findings were suggestive of viral infection.

CD38 Coordinates with NF-κB to Promote Cochlear Inflammation in Noise-Induced Hearing Loss: the Protective Effect of Apigenin.

Noise exposure is one of the most common causes of sensorineural hearing loss. Although many studies considered inflammation to be a major contributor to noise-induced hearing loss, the process of cochlear inflammation is still unclear. Studies have found that activation of the NF-κB signaling pathway results in the accumulation of macrophages in the inner ear plays an important role in hair cell damage.

Residual HCV-RNA and Elevated Platelet-to-Lymphocyte Ratio Predict Poor Long-Term Outcomes in Patients with Chronic Hepatitis C After Treatment.

Introduction: Despite achieving sustained viral response (SVR) after treatment with direct-acting antivirals (DAAs), the risk of liver disease progression and extrahepatic complications in chronic hepatitis C (CHC) remains. We aimed to determine the role of residual HCV-RNA in peripheral blood mononuclear cells (PBMCs), a condition known as occult hepatitis C (OCI), and systemic inflammatory markers as predictors of long-term outcomes in patients treated with DAAs.

Methods: We followed 42 patients treated with DAAs with OCI status determined after therapy, for a median of 6.

O-antigen of uropathogenic Escherichia coli is required for induction of neutrophil extracellular traps.

Background: Urinary tract infections (UTIs) are prevalent bacterial infection, with uropathogenic Escherichia coli (UPEC) as the primary causative agent. The outer membrane of UPEC contains a lipopolysaccharide (LPS), which plays crucial roles in the host's immune response to infection. Neutrophils use neutrophil extracellular traps (NETs) are mechanism by which neutrophils defend against bacterial infections.

Oscillatory Motion of a Camphor Disk on a Water Phase with an Ionic Liquid Sensitive to Transition Metal Ions.

We investigated oscillatory motion of a camphor disk floating on water containing 5 mM hexylethylenediaminium trifluoroacetate (HHexen-TFA) as an ionic liquid (IL). The frequency of the oscillatory motion increased with increasing concentrations of the transition metal ions Cu and Ni but was insensitive to Na, Ca, and Mg, the typical metal ions in the water phase. The surface tension of the water phase containing 5 mM HHexen-TFA also increased with increasing concentrations of Cu and Ni but was insensitive to Na, Ca, and Mg.

Feed additives for methane mitigation: A guideline to uncover the mode of action of antimethanogenic feed additives for ruminants.

This publication aims to provide guidelines of the knowledge required and the potential research to be conducted in order to understand the mode of action of antimethanogenic feed additives (AMFA). In the first part of the paper, we classify AMFA into 4 categories according to their mode of action: (1) lowering dihydrogen (H) production; (2) inhibiting methanogens; (3) promoting alternative H-incorporating pathways; and (4) oxidizing methane (CH). The second part of the paper presents questions that guide the research to identify the mode of action of an AMFA on the rumen CH production from 5 different perspectives: (1) microbiology; (2) cell and molecular biochemistry; (3) microbial ecology; (4) animal metabolism; and (5) cross-cutting aspects.
