The purpose of this study was to investigate the protective effects of beet root ( var. rubra) in lipopolysaccharide (LPS) and alcohol induced liver damage. ethanol extract (BVEE) showed good antioxidant activity in the contents of polyphenol and flavonoid compounds, and the electron-donating ability and ABTS radical scavenging activity. As for anti-inflammatory effect in RAW 264.7 cells, inhibition rate of nitric oxide production was increased in dose dependent manner. In hepatotoxicity model induced by LPS and alcohol in rat, BVEE significantly decreased serum AST, ALT and γ-GTP concentrations in a dose-dependent manner. The histopathological changes after H&E staining showed that fat accumulation and inflammatory cell infiltration were decreased by BVEE. The collagen fibers around the central lobule observed by Masson's trichrome staining were also decreased by BVEE. In addition, as for the immunohistochemical staining and Transmission electron microscopy, BVEE improved morphological characteristics of damaged liver lesion. The increased mRNA expressions of NF-κB, MAPK1, MAPK3, CYP2E1, and α-SMA were significantly decreased in BVEE treated group. These results indicated that BVEE would have protective effects in hepatotoxicity by altering various indicators related to the liver damage induced by LPS or alcohol.

Purpose Of Review: To review currently existing knowledge on a new type of antihypertensive treatment, small interfering RNA (siRNA) targeting hepatic angiotensinogen.
Recent Findings: Targeting angiotensinogen synthesis in the liver with siRNA allows reaching a suppression of renin-angiotensin system (RAS) activity for up to 6 months after 1 injection. This might revolutionize antihypertensive treatment, as it could overcome non-adherence, the major reason for inadequate blood pressure control.

Bacterial infections can induce exuberant immune responses that can damage host tissues. Previously, we demonstrated that systemic infection in mice causes tissue damage in the liver. This liver necrosis is associated with the expression of endogenous retroviruses, chromosomally integrated retroviruses that encode a reverse transcriptase.

Aim: Sepsis is a potentially fatal condition characterized by organ failure resulting from an abnormal host response to infection, often leading to liver and kidney damage. Timely recognition and intervention of these dysfunctions have the potential to significantly reduce sepsis mortality rates. Recent studies have emphasized the critical role of serum exosomes and their miRNA content in mediating sepsis-induced organ dysfunction.

Hepatic encephalopathy (HE) is a syndrome that arises from acute or chronic liver failure. This study was devised to assess the impact of a combination of boswellic acid (BA) and low doses of gamma radiation (LDR) on thioacetamide (TAA)-induced HE in an animal model. The effect of daily BA treatment (175 mg/kg body weight, for four weeks) and/or fractionated low-dose γ-radiation (LDR; 0.
