Consumption of high-fat diet (HFD) induces nonalcoholic fatty liver disease (NAFLD) and may lead to multiple complications affecting human health. In the present study, effect of Moringa oleifera leaf extract (MoLE) in alleviating HFD induced liver injury in mice has been reported. Liver histology and serum activity of hepatic marker enzymes i.e. aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) have been studied. Lipid peroxidation (LPO), ferric reducing antioxidant power (FRAP) and reduced glutathione (GSH) were also estimated using liver homogenate. Results of the study suggested that MoLE treatment protected HFD-induced liver damage as indicated by histopathology and liver enzyme activity compared to only-HFD fed group (P < 0.05). Interestingly, early signs of HFD-induced fatty liver were also alleviated by MoLE. Moreover, significant increase in endogenous antioxidant parameters and lower lipid peroxidation were found in liver of all MoLE treated groups. Results of the study indicated that MoLE has both preventive as also curative hepatoprotective activity.

Purpose Of Review: While lipid-lowering therapies demonstrate efficacy, many patients still contend with significant residual risk of atherosclerotic cardiovascular diseases (ASCVD). The intestine plays a pivotal role in regulating circulating lipoproteins levels, thereby exerting influence on ASCVD pathogenesis. This review underscores recent genetic findings from the last six years that delineate new biological pathways and actors in the intestine which regulate lipid-related ASCVD risk.

A reader of the peer-reviewed neuroscience literature will often encounter expressions like the following: 'the brain is a dynamic system', 'the brain is a complex network', or 'the brain is a highly metabolic organ'. These expressions attempt to define the essential functions and properties of the mammalian or human brain in a simple phrase or sentence, sometimes using metaphors or analogies. We sought to survey the most common phrases of the form 'the brain is…' in the biomedical literature to provide insights into current conceptualizations of the brain.

Hepatocellular carcinoma (HCC) remains a malignant and life-threatening tumor with an extremely poor prognosis, posing a significant global health challenge. Despite the continuous emergence of novel therapeutic agents, patients exhibit substantial heterogeneity in their responses to anti-tumor drugs and overall prognosis. The pentose phosphate pathway (PPP) is highly activated in various tumor cells and plays a pivotal role in tumor metabolic reprogramming.

Purpose Of Review: This narrative review explores the role of Medical Nutritional Therapy (MNT) in managing Metabolic-Associated Steatotic Liver Disease (MASLD), previously known as nonalcoholic fatty liver disease. It aims to examine the effectiveness of specific nutritional strategies in preventing and treating this obesity-linked liver disease.
Recent Findings: Emerging evidence underscores the benefits of the Mediterranean diet, low-carbohydrate diets, and intermittent fasting in reducing liver fat, improving insulin sensitivity, and mitigating inflammation.

Acute myocardial infarction (MI) remains a leading cause of mortality worldwide, with inflammatory and reparative phases playing critical roles in disease progression. Currently, there is a pressing need for imaging techniques to monitor immune cell infiltration and inflammation activity during these phases. We developed a novel probe, Tc-HYNIC-mAb, utilizing a monoclonal antibody that targets the voltage-gated potassium channel 1.
