Polycystic ovary syndrome (PCOS) is one of the most common endocrine anomalies among females of reproductive age, highlighted by hyperandrogenism. PCOS is multifactorial as it can be associated with obesity, insulin resistance, low-grade chronic inflammation, and dyslipidemia. PCOS also leads to dysbiosis by lowering microbial diversity and beneficial microbes, such as Faecalibacterium, Roseburia, Akkermenisa, and Bifidobacterium, and by causing a higher load of opportunistic pathogens, such as Escherichia/Shigella, Fusobacterium, Bilophila, and Sutterella...

High-temperature stress poses a significant environmental challenge for aquatic organisms, including tsinling lenok trout (Brachymystax lenok tsinlingensis). This study aimed to investigate the role of microRNAs (miRNAs) in inducing liver inflammation in tsinling lenok trout under high-temperature stress. Tsinling lenok trout were exposed to high-temperature conditions (24 °C) for 8 h, and liver samples were collected for analysis. Through small RNA sequencing, we identified differentially expressed miRNAs in the liver of high-temperature-stressed tsinling lenok trout compared to the control group (maintained at 16 °C)...

ALPPS enables complete tumor resection in a shorter interval and a larger number of patients than classic two-stage hepatectomies. However, there is little evidence regarding long-term outcomes in patients with colorectal liver metastases (CLM). This study aims to evaluate the short and long-term outcomes of ALPPS in patients with CRM. Single-cohort, prospective, observational study. Patients with unresectable CLM due to insufficient liver remnant who underwent ALPPS between June 2011 and June 2021 were included...

Chitobiose (COS2 ) efficiently lowers lipids in vivo and facilitates butyric acid enrichment during human fecal fermentation. However, whether COS2 can interact with butyric acid to generate a hypolipidemic effect remains unclear. This study examined the hypolipidemic mechanism of COS2 involving butyric acid, which could alleviate non-alcoholic fatty liver disease (NAFLD). The results revealed that COS2 administration modulated the β-oxidation pathway in the liver and restructured the short chain fatty acids in the fecal of ob/ob-/- mice...

BACKGROUND: Spontaneous clearance of chronic hepatitis C virus (HCV) is rare in adults. A T-lymphocyte response is thought to be involved in HCV-RNA clearance. Splenectomy reportedly has a beneficial effect on T cell immune function in patients with cirrhosis. To the best of our knowledge, the present report is the first to describe spontaneous clearance of serum HCV-RNA within 1 year after splenectomy in a patient with cirrhosis. CASE PRESENTATION: A 55-year-old man with HCV cirrhosis was transferred to our institution with advanced pancytopenia, splenomegaly, and gastric varices...

The transition-metal-catalyzed [4 + 4] cycloaddition leading to cyclooctanoids has been centralizing on dimerization between 1,3-diene type substrates. Here, we extend a [4σ + 4π - 1] and [4σ + 4π] cycloaddition strategy to access the 7/8-membered fused carbocycles through Rh-catalyzed coupling between the 4σ-donor (benzocyclobutenones) and pendant diene (4π) motifs. The two pathways can be controlled by adjusting the solvated CO concentration. A broad scope (>40 examples) of 5-6-7 and 5-6-8 polyfused carbocycles was obtained with good yields (up to 90%)...

BACKGROUND: Acute allograft rejection is a well-known complication of liver transplantation (LT). The incidence, epidemiology and outcomes of acute rejection have not been well-described in Australia. METHODS: We retrospectively studied consecutive adults who underwent deceased-donor LT at a single centre between 2010-2020. Donor and recipient data at time of LT and recipient outcomes were collected from a prospective LT database. Liver biopsy reports were reviewed and only a graft's first instance of biopsy-proven acute rejection was analysed...

Persistent transcription of HBV covalently closed circular DNA (cccDNA) is critical for chronic HBV infection. Silencing cccDNA transcription through epigenetic mechanisms offers an effective strategy to control HBV. Long non-coding RNAs (lncRNAs), as important epigenetic regulators, have an unclear role in cccDNA transcription regulation. In this study, lncRNA sequencing (lncRNA seq) is conducted on five pairs of HBV-positive and HBV-negative liver tissue. Through analysis, HOXA-AS2 (HOXA cluster antisense RNA 2) is identified as a significantly upregulated lncRNA in HBV-infected livers...

With the increasing use of oral contraceptives and estrogen replacement therapy, the incidence of estrogen-induced cholestasis (EC) has tended to rise. Psoralen (P) and isopsoralen (IP) are the major bioactive components in Psoraleae Fructus, and their estrogen-like activities have already been recognized. Recent studies have also reported that ERK1/2 plays a critical role in EC in mice. This study aimed to investigate whether P and IP induce EC and reveal specific mechanisms. It was found that P and IP increased the expression of esr1 , cyp19a1b and the levels of E2 and VTG at 80 μM in zebrafish larvae...

Sepsis is a leading cause of mortality worldwide, and pneumonia is the most common cause of sepsis in humans. Low levels of high-density lipoprotein cholesterol (HDL-C) levels are associated with an increased risk of death from sepsis, and increasing levels of HDL-C by inhibition of cholesteryl ester transfer protein (CETP) decreases mortality from intraabdominal polymicrobial sepsis in APOE*3-Leiden.CETP mice. Here, we show that treatment with the CETP inhibitor (CETPi) anacetrapib reduced mortality from Streptococcus pneumoniae-induced sepsis in APOE*3-Leiden...
