Amplified response of drug-induced liver fibrosis immune cell co-culture in a 3D hepatic fibrosis model.

Liver fibrosis, a critical consequence of chronic liver diseases, is characterized by excessive extracellular matrix (ECM) deposition driven by inflammation. This process involves complex interactions among hepatocytes, hepatic stellate cells (HSCs), and Kupffer cells, the liver's resident macrophages. Kupffer cells are essential in initiating fibrosis through the release of pro-inflammatory cytokines that activate HSCs.

In Vitro Nonalcoholic Fatty Liver Disease Model Elucidating the Effect of Immune Environment on Disease Progression and Alleviation.

Nonalcoholic fatty liver disease (NAFLD), which is a major cause of chronic liver disease, is characterized by fat accumulation in the liver. Existing models struggle to assess medication effects on liver function in the context of NAFLD's unique inflammatory environment. We address this by developing a 3D in vitro NAFLD model using HepG2 and THP-1 cells (mimicking liver and Kupffer cells) cocultured using transwell and hydrogel system.

Evaluating the validity of the nursing statements algorithmically generated based on the International Classifications of Nursing Practice for respiratory nursing care using large language models.

Objective: This study aims to facilitate the creation of quality standardized nursing statements in South Korea's hospitals using algorithmic generation based on the International Classifications of Nursing Practice (ICNP) and evaluation through Large Language Models.

Materials And Methods: We algorithmically generated 15 972 statements related to acute respiratory care using 117 concepts and concept composition models of ICNP. Human reviewers, Generative Pre-trained Transformers 4.

CO-Induced TTP Activation Alleviates Cellular Senescence and Age-Dependent Hepatic Steatosis Downregulation of .

Aging can increase the risk of various hepatic diseases, especially non-alcoholic fatty liver disease (NAFLD). Although the mechanisms underlying the pathogenesis of age-related disorders such as NAFLD remain incompletely understood, recent studies have implicated the accumulation of senescent cells as a contributing factor. Here, we show that tristetraprolin (TTP) deficiency accelerates NAFLD during aging by enhancing the senescence-associated secretory phenotype (SASP) as well as several hallmarks of senescence.

NRBF2-mediated autophagy contributes to metabolite replenishment and radioresistance in glioblastoma.

Overcoming therapeutic resistance in glioblastoma (GBM) is an essential strategy for improving cancer therapy. However, cancer cells possess various evasion mechanisms, such as metabolic reprogramming, which promote cell survival and limit therapy. The diverse metabolic fuel sources that are produced by autophagy provide tumors with metabolic plasticity and are known to induce drug or radioresistance in GBM.

Baiap3 regulates depressive behaviors in mice via attenuating dense core vesicle trafficking in subsets of prefrontal cortex neurons.

Selective serotonin reuptake inhibitors (SSRIs) are effective first line therapies for treating depression, but are plagued by undesirable side effects and are not effective in all patients. Because SSRIs effectively deplete the neuronal releasable serotonin (5-HT) pool, gaining a deeper understanding of intracellular mechanisms regulating 5-HT pools can help us understand the shortcomings of SSRIs and develop more effective therapies. In this study, we found that BAIAP3 (brain-specific angiogenesis inhibitor 1-associated protein 3) is significantly downregulated in two mouse models of depression (the IR- and CUMS-induced depressive mouse models).

Autophagic Organelles in DNA Damage Response.

Autophagy is an important subcellular event engaged in the maintenance of cellular homeostasis the degradation of cargo proteins and malfunctioning organelles. In response to cellular stresses, like nutrient deprivation, infection, and DNA damaging agents, autophagy is activated to reduce the damage and restore cellular homeostasis. One of the responses to cellular stresses is the DNA damage response (DDR), the intracellular pathway that senses and repairs damaged DNA.

Organ-Specific Effects of Low Dose Radiation Exposure: A Comprehensive Review.

Ionizing radiation (IR) is a high-energy radiation whose biological effects depend on the irradiation doses. Low-dose radiation (LDR) is delivered during medical diagnoses or by an exposure to radioactive elements and has been linked to the occurrence of chronic diseases, such as leukemia and cardiovascular diseases. Though epidemiological research is indispensable for predicting and dealing with LDR-induced abnormalities in individuals exposed to LDR, little is known about epidemiological markers of LDR exposure.

Low dose radiation attenuates inflammation and promotes wound healing in a mouse burn model.

Background: Burn injuries are devastating traumas that functionally affect a variety of organ systems. As intensive inflammatory responses induced by burns can lead to multiple organ failures and impaired skin regeneration increases risk of infectious complex, multimodal therapeutic approaches are needed.

Objectives: To investigate the role of low dose radiation (LDR) treatment for regulation of excessive inflammation and wound healing after burn injury.

Effects of selected herb extracts on iron-catalyzed lipid oxidation in soybean oil-in-water emulsion.

Effect of herb extracts on the oil oxidation of an oil-in-water emulsion containing iron was studied. The emulsion comprised tocopherol-stripped soybean oil (40 g), citrate buffer (60 g, pH 4.0), xanthan gum (35mg), and FeSO (0.

Identification of a tolerant locus on Arabidopsis thaliana to hypervirulent beet curly top virus CFH strain.

The infection of hosts by the geminivirus depends on the interactions between host and viral factors for viral DNA replication, viral gene expression, and the movement of virus throughout the hosts. This work reports that a hypervirulent strain of Beet curly top virus (BCTV) is different in its ability to infect several ecotypes of Arabidopsis thaliana. Symptoms appeared on Arabidopsis ecotypes around 7 to 10 d after inoculation with BCTV-CFH.
