Background: This study aimed to investigate the effects of niacin combined with F1-7 on the improvement of alcoholic fatty liver disease (AFLD) in mice and its potential regulatory mechanism.

Methods: A total of 75 8-week-old male C57BL/6N mice were acclimated for one week and randomly divided into five groups: control group, alcohol model group (AFLD), niacin intervention group (NA), F1-7 intervention group (F1-7), and niacin combined with F1-7 intervention group (NF). The experiment lasted for 8 weeks.

Diffuse axonal injury (DAI) results in aberrant functional connectivity and is significantly linked to cognitive impairment. Nevertheless, the network mechanisms influencing neurocognitive function following DAI remain unclear. This study aimed to examine the characteristics of static and dynamic functional network connectivity (FNC) in patients with DAI.

Neuroimaging studies have indicated that altered cerebral blood flow (CBF) was associated with the long-term symptoms of postacute sequelae of SARS-CoV-2 infection (PASC), also known as "long COVID". COVID-19 and long COVID were found to be strongly associated with host gene expression. Nevertheless, the relationships between altered CBF, clinical symptoms, and gene expression in the central nervous system (CNS) remain unclear in individuals with long COVID.

Affect plays a pivotal role in fostering creative performance, and there is increasing recognition that different levels and types of affect may exert distinct impacts on creative performance. Drawing upon self-determination theory, this study aims to explore a novel classification of affect-affect under need satisfaction and need thwarting-and examine its relationship with creative performance. Study 1 involved 75 participants to investigate the content of affect under need satisfaction and need thwarting.

Approximately 36% of patients with neuromyelitis optica spectrum disorders (NMOSD) suffer from severe visual and motor disability (blindness or light perception or unable to walk) with abnormalities of whole-brain functional networks. However, it remains unclear how whole-brain functional networks and their dynamic properties are related to clinical disability in patients with NMOSD. Our study recruited 30 NMOSD patients (37.

The dysfunction of intestinal microbiota and bile acid metabolism is related to the pathogenesis of atherosclerosis. This study we explored the mechanism of subsp. F1-7 ( F1-7), improving atherosclerosis by regulating the bile acid metabolism and intestinal microbiota in the ApoE mice.

The aim is to investigate the application of periodontal tissue regeneration combined with orthodontics in oral restoration, and explore its effect and significance on the expressions of Interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α) and interleukin-5 (IL-5) in periodontal tissue. The patients in observation group were treated with orthodontics combined with periodontal tissue regeneration, and the control group was treated with periodontal tissue regeneration. The total effective rate, adverse reactions, recurrence rate and treatment satisfaction were compared.

Background: Growing evidence suggests that excessive inflammation hampers the regenerative capacity of periodontal ligament cells (PDLCs) and that activation of the Wnt/β-catenin pathway is crucial in suppressing immune dysregulation.

Objective: This study aimed to establish the role of the Wnt/β-catenin in regulating the immune microenvironment and its subsequent impact on periodontal regeneration.

Methods: Lithium chloride (LiCl, Wnt activator) was administered daily into the standard periodontal defects created in 12-week-old Lewis rats.

Background: Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease and has become a public health concern worldwide. The hallmark of NAFLD is hepatic steatosis. Therefore, there is an urgent need to develop new therapeutic strategies that are efficacious and have minimal side effects in hepatic steatosis and NAFLD treatment.

Atherosclerosis is a major cause of cardiovascular disease caused by high cholesterol. Reduced intestinal cholesterol absorption has been shown to exert strong cholesterol-lowering and antiatherogenic effects. Previously, we reported that curcumin reduced cholesterol absorption in high-fat diet-fed hamster by downregulating the intestinal expression of Niemann-Pick C1-like 1.

Hepatocellular carcinoma (HCC) is a highly heterogeneous type of tumor, which may be caused by the stem/progenitor cell features of particular HCC cells. Recent studies have subclassified HCC into different prognostic subtypes according to just one stemness-associated marker. However, one stemness-associated marker is not sufficient to clearly define cancer stem cells, or to decipher the heterogeneous nature of HCC.

Toll-like receptor 4 (TLR4) has been reported to play a critical role in the pathogenesis of atherosclerosis, the current study aimed to investigate whether curcumin suppresses atherosclerosis development in ApoE-knockout (ApoE) mice by inhibiting TLR4 expression. ApoE mice were fed a high-fat diet supplemented with or without curcumin (0.1% w/w) for 16 weeks.

Accumulating evidence suggests that the tumor microenvironment has a profound influence on tumor initiation and progression, opening a new avenue for studying tumor biology. Nonetheless, the prognostic values of the peritumoral expression of EpCAM and CD13 remain to be elucidated in hepatocellular carcinoma (HCC) patients. In this study, the expression of EpCAM and CD13 was assessed by immunohistochemistry in peritumoral liver hepatocytes from 106 hepatitis B virus- (HBV-) related HCC patients who had undergone curative hepatectomy.

Purpose: Gastric cancer studies indicated a potential correlation between circulating tumor cells (CTCs) in peripheral blood and tumor relapse/metastasis. The prevalence and significance of circulating tumor microemboli (CTM) in gastric cancer remain unknown. We investigated the prevalence and prognostic value of CTCs and CTM for progression-free survival (PFS) and overall survival (OS) in gastric cancer patients.

Colorectal cancer is one of the major causes of death from cancer. Metastasis is the leading cause of treatment failure, in which cancer stem cells and circulating tumor cells play crucial roles. Identifying the involved metastatic biomarkers and clarifying the regulation mechanisms are of great importance for targeting tumor metastasis.

Background: Circulating tumor cells (CTCs) detected in peripheral blood (PB) of cancer patients can be identified as isolated CTCs and circulating tumor microemboli (CTM). This study aimed to evaluate the prognostic value of CTM detection and CTC phenotype in advanced colorectal cancer (CRC) patients during chemotherapy.

Methods: A size-based platform for CTC isolation was applied.

Purpose: Loss of P53 binding protein 1 (53BP1) is considered a poor prognostic factor for colorectal cancer. However, its effect on chemosensitivity of colorectal cancer to 5-fluorouracil (5-FU) remains elusive. This study aimed to examine the association of 53BP1 expression with chemosensitivity of colorectal cancer cells to 5-FU.

The present study aimed to observe the influence of p53 binding protein 1 (53BP1) silencing on the radiosensitivity of colorectal cancer (CRC) cells and investigated the potential underlying mechanisms. The differences in radiosensitivity among four CRC cells were detected by the clone formation assay, while the expression of their 53BP1 was detected by the western blot analysis. HCT116 cells with relatively high expression of 53BP1 were selected to silence the expression of 53BP1 by shRNA intervention.
