Liquid-liquid phase separation in hepatocellular carcinoma.

Liquid-liquid phase separation (LLPS) drives the formation of membraneless intracellular compartments within both cytoplasm and nucleus. These compartments can form distinct physicochemical environments, and in particular display different concentrations of proteins, RNA, and macromolecules compared to the surrounding cytosol. Recent studies have highlighted the significant role of aberrant LLPS in cancer development and progression, impacting many core processes such as oncogenic signalling pathways, transcriptional dysregulation, and genome instability.

Reciprocal tumor-platelet interaction through the EPHB1-EFNB1 axis in the liver metastatic niche promotes metastatic tumor outgrowth in pancreatic ductal adenocarcinoma.

Background: The interaction between the metastatic microenvironment and tumor cells plays an important role in metastatic tumor formation. Platelets play pivotal roles in hematogenous cancer metastasis through tumor cell-platelet interaction in blood vessels. Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal malignancy distinguished by its notable tendency to metastasize to the liver.

Non-linear association of liver enzymes with cognitive performance in the elderly: A cross-sectional study.

Background: Although liver metabolic dysfunction has been found to potentially elevate susceptibility to cognitive impairment and dementia, there is still insufficient evidence to explore the non-linear association of liver enzymes with cognitive performance. Therefore, we aimed to elucidate the non-linear relationship between liver enzymes and cognitive performance.

Methods: In this cross-sectional study, 2764 individuals aged ≥ 60 who participated in the National Health and Nutrition Survey (NHANES) between 2011 and 2014 were included.

Methods: The clinical data of CML-BP patients who received the first major hematological response after induction therapy at The Affiliated Cancer Hospital of Zhengzhou University from June 2015 to December 2021 were analyzed retrospectively. The event-free survival, duration of remission, and overall survival of patients in TKI combined with decitabine, homoharringtonine, interferon group(=18) and TKI combined with conventional chemotherapy group(=10) were compared by log-rank test.

4-OI ameliorates bleomycin-induced pulmonary fibrosis by activating Nrf2 and suppressing macrophage-mediated epithelial-mesenchymal transition.

Objectives: Pulmonary fibrosis (PF) is a chronic and refractory interstitial lung disease with limited therapeutic options. 4-octyl itaconate (4-OI), a cell-permeable derivative of itaconate, has been shown to have anti-oxidative and anti-inflammatory properties. However, the effect and the underlying mechanism of 4-OI on PF are still unknown.

Sugar infusion into trees: A novel method to study tree carbon relations and its regulations.

Many carbon-related physiological questions in plants such as carbon (C) limitation or starvation have not yet been resolved thoroughly due to the lack of suitable experimental methodology. As a first step towards resolving these problems, we conducted infusion experiments with bonsai trees () and young maple trees () in greenhouse, and with adult Scots pine trees () in the field, that were "fed" with C-labelled glucose either through the phloem or the xylem. We then traced the C-signal in plant organic matter and respiration to test whether trees can take up and metabolize exogenous sugars infused.

Identifying the Risk Factors for Postoperative Sore Throat After Endotracheal Intubation for Oral and Maxillofacial Surgery.

Objective: To identify risk factors for postoperative sore throat (POST) after general anesthesia in oral and maxillOfacial surgery.

Material And Methods: This study is a retrospective cohort design study. We enrolled patients with oral and maxillofacial surgery who underwent endotracheal intubation under general anesthesia in the Stomatology Hospital, Zhejiang University School Of Medicine between April 2020 and April 2021.

Coadaptation fostered by the SLIT2-ROBO1 axis facilitates liver metastasis of pancreatic ductal adenocarcinoma.

To explore the mechanism of coadaptation and the potential drivers of pancreatic ductal adenocarcinoma (PDAC) metastasis to the liver, we study key molecules involved in this process and their translational value. Premetastatic niche (PMN) and macrometastatic niche (MMN) formation in a mouse model is observed via CT combined with 3D organ reconstruction bioluminescence imaging, and then we screen slit guidance ligand 2 (SLIT2) and its receptor roundabout guidance receptor 1 (ROBO1) as important factors. After we confirm the expression and distribution of SLIT2 and ROBO1 in samples from PDAC patients and several mouse models, we discover that SLIT2-ROBO1-mediated coadaptation facilitated the implantation and outgrowth of PDAC disseminated tumour cells (DTCs) in the liver.

Emerging roles of non-coding RNAs in colorectal cancer oxaliplatin resistance and liquid biopsy potential.

Colorectal cancer (CRC) is one of the most common malignancies of the digestive tract, with the annual incidence and mortality increasing consistently. Oxaliplatin-based chemotherapy is a preferred therapeutic regimen for patients with advanced CRC. However, most patients will inevitably develop resistance to oxaliplatin.

A circuit from the ventral subiculum to anterior hypothalamic nucleus GABAergic neurons essential for anxiety-like behavioral avoidance.

Behavioral observations suggest a connection between anxiety and predator defense, but the underlying neural mechanisms remain unclear. Here we examine the role of the anterior hypothalamic nucleus (AHN), a node in the predator defense network, in anxiety-like behaviors. By in vivo recordings in male mice, we find that activity of AHN GABAergic (AHN) neurons shows individually stable increases when animals approach unfamiliar objects in an open field (OF) or when they explore the open-arm of an elevated plus-maze (EPM).

Agomelatine: a potential novel approach for the treatment of memory disorder in neurodegenerative disease.

Agomelatine is a selective agonist of melatonin receptor 1A/melatonin receptor 1B (MT/MT) and antagonist of 5-hydroxytryptamine 2C receptors. It is used clinically to treat major depressive episodes in adults. The pro-chronobiological activity of agomelatine reconstructs sleep-wake rhythms and normalizes circadian disturbances via its agonistic effect of melatonin receptor 1A/melatonin receptor 1B, which work simultaneously to counteract depression and anxiety disorder.

Attapulgite Structure Reset to Accelerate the Crystal Transformation of Isotactic Polybutene.

Isotactic polybutene (iPB) has a wide application in the water pipe field. However, the most valuable form I, needs 7 days to complete the transformation. In this study, the attapulgite (ATP), which produces lattice matching of the iPB form I, was selected to prepare an iPB/ATP composite.

Background: Astragalus (Hedysarum Multijugum Maxim., Huangqi) is a Chinese herbal medicine, and according to the theory of traditional Chinese medicine (TCM), Chinese medicinal preparations containing astragalus can be used clinically to treat radiation-induced lung injury (RILI). To systematically review the efficacy and safety of Chinese medicinal preparations containing astragalus in the prevention and treatment of RILI by means of meta-analysis.

Sexually dimorphic effects of estrogen receptor 2 deletion in the dorsal raphe nucleus on emotional behaviors.

Sex differences in emotional behaviors and affective disorders have been widely noted, of which sexually dimorphic secretion of gonadal steroid hormones such as estrogen is suspected to play a role. However, the underlying neural mechanisms remain poorly understood. We noted that the expression of estrogen receptor 2 (Esr2, or ERβ), a key mediator of estrogen signaling in the brain, was enriched in the dorsal raphe nucleus (DRN), a region involved in emotion regulation.
