Nutritional Counseling and Mediterranean Diet in Adrenoleukodystrophy: A Real-Life Experience.

Background/Objectives: Adrenoleukodystrophy (X-ALD) is a metabolic disorder caused by dysfunctional peroxisomal beta-oxidation of very-long-chain fatty acids (VLCFAs). A VLCFA-restricted Mediterranean diet has been proposed for patients and carriers to reduce daily VLCFA intake. Methods: We retrospectively evaluated plasma VLCFAs in a cohort of 36 patients and 20 carriers at baseline and after 1 year of restricted diet. Results: At T1, compliant adult patients had significantly lower C26:0 levels [1.7 (1.2) vs. 2.5 µmol/L (1.7), p < 0.05], C26:0/C22:0 ratio [0.04 (0.02) vs. 0.06 (0.03), p < 0.05], and triglycerides [93 (56.5) vs. 128 mg/dL (109.5), p < 0.05] than non-compliant ones. C26:0 [2.4 (1.7) vs. 1.7 (1.2) µmol/L, p < 0.05], the C26:0/C22:0 ratio [0.06 (0.04) vs. 0.04 (0.02), p < 0.05], and cholesterol [173.5 (68.3) mg/dL vs. 157 (54) mg/dL, p < 0.05] were significantly reduced in compliant adult patients at T1 vs. baseline. As for carriers, the C26:0/C22:0 ratio was lower [0.02 (0.01) vs. 0.04 (0.009), p < 0.05] at T1 in compliant carriers, as compared to non-compliant ones. The C26:0/C22:0 [0.03 (0.02) vs. 0.02 (0.01) p < 0.05] and C24:0/C22:0 [1.0 (0.2) vs. 0.9 (0.3), p < 0.05] ratios were significantly decreased at T1 vs. T0. Conclusions: A VLCFA-restricted diet is effective in reducing plasma VLCFA levels and their ratios and must be strongly encouraged as support to therapy.

Enhancing Charge Trapping Performance of Hafnia Thin Films Using Sequential Plasma Atomic Layer Deposition.

We aimed to fabricate reliable memory devices using HfO2, which is gaining attention as a charge-trapping layer material for next-generation NAND flash memory. To this end, a new atomic layer deposition process using sequential remote plasma (RP) and direct plasma (DP) was designed to create charge-trapping memory devices. Subsequently, the operational characteristics of the devices were analyzed based on the thickness ratio of thin films deposited using the sequential RP and DP processes. As the thickness of the initially RP-deposited thin film increased, the memory window and retention also increased, while the interface defect density and leakage current decreased. When the thickness of the RP-deposited thin film was 7 nm, a maximum memory window of 10.1 V was achieved at an operating voltage of ±10 V, and the interface trap density (Dit) reached a minimum value of 1.0 × 1012 eV-1cm-2. Once the RP-deposited thin film reaches a certain thickness, the ion bombardment effect from DP on the substrate is expected to decrease, improving the Si/SiO2/HfO2 interface and thereby enhancing device endurance and reliability. This study confirmed that the proposed sequential RP and DP deposition processes could resolve issues related to unstable interface layers, improve device performance, and enhance process throughput.

Fumed-Si-Pr-Ald-Barb as a Fluorescent Chemosensor for the Hg2+ Detection and Cr2O72- Ions: A Combined Experimental and Computational Perspective.

The surface of fumed silica nanoparticles was modified by pyridine carbaldehyde and barbituric acid to provide fumed-Si-Pr-Ald-Barb. The structure was identified and investigated through diverse techniques, such as FT-IR, EDX, Mapping, BET, XRD, SEM, and TGA. This nanocomposite was used to detect different cations and anions in a mixture of H2O:EtOH. The results showed that fumed-Si-Pr-Ald-Barb can selectively detect Hg2+ and Cr2O72- ions. The detection limits were calculated at about 5.4 × 10-3 M for Hg2+ and 3.3 × 10-3 M for Cr2O72- ions. A computational method (DFT) was applied to determine the active sites on the Pr-Ald-Barb for electrophilic and nucleophilic attacks. The HOMO-LUMO molecular orbital was calculated by B3LYP/6-311G(d,p)/LANL2DZ theoretical methods. The energy gap for the Pr-Ald-Barb and Pr-Ald-Barb+ion complexes was predicted by the EHOMO and ELUMO values. The DFT calculation confirms the suggested experimental mechanism for interacting the Pr-Ald-Barb with ions.

The Application of Ultrasound Pre-Treatment in Low-Temperature Synthesis of Zinc Oxide Nanorods.

Zinc oxide, due to its unique physicochemical properties, including dual piezoelectric and semiconductive ones, demonstrates a high application potential in various fields, with a particular focus on nanotechnology. Among ZnO nanoforms, nanorods are gaining particular interest. Due to their ability to efficiently transport charge carriers and photoelectric properties, they demonstrate significant potential in energy storage and conversion, as well as photovoltaics. They can be prepared via various methods; however, most of them require large energy inputs, long reaction times, or high-cost equipment. Hence, new methods of ZnO nanorod fabrication are currently being sought out. In this paper, an ultrasound-supported synthesis of ZnO nanorods with zinc acetate as a zinc precursor has been described. The fabrication of nanorods included the treatment of the precursor solution with ultrasounds, wherein various sonication times were employed to verify the impact of the sonication process on the effectiveness of ZnO nanorod synthesis and the sizes of the obtained nanostructures. The morphology of the obtained ZnO nanorods was imaged via a scanning electron microscope (SEM) analysis, while the particle size distribution within the precursor suspensions was determined by means of dynamic light scattering (DLS). Additionally, the dynamic viscosity of precursor suspensions was also verified. It was demonstrated that ultrasounds positively affect ZnO nanorod synthesis, yielding longer nanostructures through even reactant distribution. Longer nanorods were obtained as a result of short sonication (1-3 min), wherein prolonged treatment with ultrasounds (4-5 min) resulted in obtaining shorter nanorods. Importantly, the application of ultrasounds increased particle homogeneity within the precursor suspension by disintegrating particle agglomerates. Moreover, it was demonstrated that ultrasonic treatment reduces the dynamic viscosity of precursor suspension, facilitating faster particle diffusion and promoting a more uniform growth of longer ZnO nanorods. Hence, it can be concluded that ultrasounds constitute a promising solution in obtaining homogeneous ZnO nanorods, which is in line with the principles of green chemistry.

Leveraging Bayesian Optimization Software for Atomic Layer Deposition: Single-Objective Optimization of TiO2 Layers.

We demonstrate the application of free-to-use and easy-to-implement Bayesian optimization (BO) software to streamline atomic layer deposition (ALD) process optimization. By employing machine learning-based Bayesian optimization algorithms, we enhanced the silicon surface passivation quality of titanium dioxide layers deposited using titanium tetraisopropoxide (TTIP). Unlike classical designs of experimental methods, such as Box-Behnken or Plackett-Burman designs, which require a predefined set of experiments and can become resource intensive, BO offers several advantages. It dynamically updates the search strategy based on previous outcomes, allowing for efficient exploration of parameter spaces with fewer experimental runs. This adaptive approach is particularly advantageous in small-scale experiments or laboratories where time, resources, and materials are limited. In a single-objective optimization experiment, we identified constrained search spaces that limited further optimization, underscoring the importance of properly defined parameter bounds prior to the optimization process. Our findings highlight that Bayesian optimization can not only reduce time and resource costs associated with ALD process optimization but also support faster discovery of more optimal ALD process parameters, even with minimal prior knowledge of the deposition process or precursor chemistry.

Impact of GLP-1RA on the Risk of Adverse Liver Outcomes Among Patients With Alcohol-Associated Liver Disease and Type 2 Diabetes.

BACKGROUND AND AIMS: We sought to characterise the impact of GLP-1RA on adverse liver outcomes (ALO) among patients with alcohol-associated liver disease (ALD) and Type 2 diabetes mellitus (T2DM). METHODS: Patients with T2DM newly diagnosed with ALD between 2013 and 2020 were identified using IBM MarketScan database and were categorised by GLP-1RA exposure. Overlap propensity score weighting (OPSW) followed by Poisson regression models was used to analyse adjusted risk of ALO, a composite endpoint defined by first occurrence of hepatic decompensation (HD), portal hypertension (PH), hepatocellular carcinoma (HCC) or liver transplantation (LT) relative to GLP-1RA. RESULTS: Among 14 730 patients, most individuals were male (n = 9752, 66.2%) with median age of 57 (IQR 52-61) years; 2.2% (n = 317) of patients had GLP-1RA exposure. Overall, 32.0% (n = 4717) of patients experienced HD, 15.9% (n = 2345) had PH, 3.8% (n = 563) developed HCC, while 2.5% (n = 374) underwent transplantation. Non-GLP-1RA patients had higher incidence of HD (32.2% vs. 22.4%) and HCC (3.9% vs. 0.3%) versus patients taking GLP-1RA (both p < 0.001); in contrast, there was no difference in incidence of PH (14.5% vs. 16.0%) and LT (1.3% vs. 2.6%) (both p > 0.05). After OPSW, overall incidence of ALO was lower in GLP-1RA cohort (GLP-1RA: 12.0%, 95%CI 9.0-16.0 vs. non-GLP-1RA: 21.0%, 95%CI 20.0-22.0) with an absolute incidence risk reduction of 9.0% (95%CI 3.0%-15.0%) associated with GLP-1RA. GLP-1RA was most strongly associated with lower likelihood of HD with reduced adjusted incidence rate of 0.56 (95%CI 0.36-0.86) relative to non-GLP-1RA individuals. CONCLUSIONS: GLP-1RA may have a hepatoprotective impact among patients with ALD and T2DM.

Alcohol-associated liver disease - a current overview.

Alcohol-associated liver disease (ALD) remains a major and increasingly pressing concern in hepatology. ALD includes spectrum of conditions, each with unique diagnostic and therapeutic challenges. Excessive alcohol intake is a leading preventable cause of physical harm, including ALD. The pathogenesis of ALD involves oxidative stress, inflammation, and lipid metabolism disruptions, with genetic predispositions playing a major role. ALD progresses from hepatic steatosis to steatohepatitis, and finally liver cirrhosis, which is marked by severe fibrosis and impaired liver function. Advanced ALD stages, particularly alcoholic hepatitis and liver cirrhosis, are characterized by high mortality rates. Management of ALD primarily involves strict abstinence from alcohol, which can reverse early-stage disease or halt progression. Nutritional support, vitamin supplementation, and symptomatic treatment are also essential. Liver transplantation is the only definitive treatment for alcoholic liver cirrhosis, but it is difficult for patients with a history of alcohol abuse to qualify for the procedure. Epidemiological data indicate a growing burden of ALD, especially among younger populations, exacerbated by increased alcohol consumption trends and the COVID-19 pandemic's influence on drinking behaviors. Despite ALD's significant impact, current therapies are limited, highlight- ing the need for innovative treatments and comprehensive patient management strategies. Individualized care, enhanced epidemiological research, and new therapeutic approaches are crucial to improving outcomes for ALD patients.

Multicomponent Gas Sensing Fiber Probe System Based on Platinum Coated Capillary Enhanced Raman Spectroscopy.

This paper proposes a novel multicomponent gas-sensing optical fiber probe system. It utilizes a precisely engineered Platinum-coated capillary fabricated via Atomic Layer Deposition (ALD) technology as the core for enhanced Raman spectroscopy, marking the first application of ALD in creating such a structure for gas Raman sensing. The noble metal capillary gas Raman probe demonstrates a low detection limit of 55 ppm for CO2 with a 30 s exposure time and good repeatability in multicomponent gas sensing. The capillary exhibits excellent stability, environmental resistance, and a large core diameter, enabling a rapid gas exchange rate and making it suitable for practical applications.

MicroRNAs in metabolic dysfunction-associated diseases: Pathogenesis and therapeutic opportunities.

Metabolic dysfunction-associated diseases often refer to various diseases caused by metabolic problems such as glucose and lipid metabolism disorders. With the improvement of living standards, the increasing prevalence of metabolic diseases has become a severe public health problem, including metabolic dysfunction-associated steatotic liver disease (MASLD), alcohol-related liver disease (ALD), diabetes and obesity. These diseases are both independent and interdependent, with complex and diverse molecular mechanisms. Therefore, it is urgent to explore the molecular mechanisms and find effective therapeutic targets of these diseases. MicroRNAs (miRNAs) have emerged as key regulators of metabolic homoeostasis due to their multitargets and network regulatory properties within the past few decades. In this review, we discussed the latest progress in the roles of miRNA-mediated regulatory networks in the development and progression of MASLD, ALD, diabetes and obesity.

Comparative Study on Hepatoprotective Effects of Traditional Herbs, Roots of Angelica gigas Nakai, Glycyrrhiza uralensis Fischer, Zizyphus jujuba Mill., and Fruits of Paeonia lactiflora Pall., on Ethanol-Induced Liver Injury in Mice.

Alcohol-associated liver disease (ALD) is a major cause of chronic liver disease, with few effective treatments besides alcohol abstinence. Angelicae Gigantis Radix (AG), Glycyrrhizae Radix et Rhizoma (GR), Paeoniae Radix (PR), and Zizyphi Fructus (ZF) are traditional herbs used to treat various ailments, including liver diseases. While several studies have reported the beneficial effects of GR on ALD, the effects of AG, PR, and ZF remain underexplored. Therefore, their efficacy and mechanisms against ALD were investigated using an alcohol-related liver injury model. The model was induced by ethanol gavage in C57BL/6J mice for 14 days, followed by oral administration of AG, GR, PR, and ZF one hour post-induction. The administration of these herbs reduced liver weight, and improved serum biomarkers of liver injury (ALT, AST, albumin). The herbs enhanced hepatic antioxidant capacity (GSH, SOD, catalase) and suppressed the production of proinflammatory cytokines (TNF-α, IL-1ß) and apoptotic changes (caspase-3). The mechanisms of action involved lipid-lowering gene modulation through regulation of the cytochrome P450 2E1/Sirtuin 1/Nrf2 pathways. Histopathological and immunohistochemical analyses revealed that these herbs attenuated hepatocyte damage and steatosis via antioxidant, anti-inflammatory, and antiapoptotic effects. These findings suggest that traditional herbs, particularly AG, could be promising alternative therapies for treating ALD.

Androgen Effects on Alcohol-induced Liver Fibrosis Are Controlled by a Notch-dependent Epigenetic Switch.

BACKGROUND & AIMS: Alcohol-associated liver disease (ALD) is a major cause of alcohol-related mortality. Sex is an important variable; however, the mechanism behind sex differences is not yet established. METHODS: Kdm5b flox/flox Kdm5c flox male mice were subjected to gonadectomy or sham surgery. Mice were fed a Western diet and 20% alcohol in the drinking water for 18 weeks. To induce knockout, mice received 2 × 1011 genome copies of AAV8-CMV-Cre or AAV8-control. To test the role of Notch, mice were treated with 10 mg/kg of avagacestat for 4 weeks. RESULTS: We found that Kdm5b/Kdm5c knockout promoted alcohol-induced liver disease, whereas gonadectomy abolished this effect, suggesting that male sex hormones promote liver disease in the absence of KDM5 demethylases. In contrast, in the thioacetamide-induced fibrosis model, male sex hormones showed a protective effect regardless of genotype. In human liver disease samples, we found that androgen receptor expression positively correlated with fibrosis levels when KDM5B levels were low and negatively when KDM5B was high, suggesting that a KDM5B-dependent epigenetic state defines the androgen receptor role in liver fibrosis. Using isolated cells, we found that this difference was due to the differential effect of testosterone on hepatic stellate cell activation in the absence or presence of KDM5B/KDM5C. Moreover, this effect was mediated by KDM5-dependent suppression of Notch signaling. In KDM5-deficient mice, Notch3 and Jag1 gene expression was induced, facilitating testosterone-mediated induction of Notch signaling and stellate cell activation. Inhibiting Notch with avagacestat greatly reduced liver fibrosis and abolished the effect of Kdm5b/Kdm5c loss. CONCLUSIONS: Male sex hormone signaling can promote or prevent alcohol-associated liver fibrosis depending on the KDM5-dependent epigenetic state.

Portal Fibrosis and the Ductular Reaction: Pathophysiological Role in the Progression of Liver Disease and Translational Opportunities.

A consistent feature of chronic liver diseases and the hallmark of pathologic repair is the so-called "ductular reaction." This is a histologic abnormality characterized by an expansion of dysmorphic cholangiocytes inside and around portal spaces infiltrated by inflammatory, mesenchymal, and vascular cells. The ductular reaction is a highly regulated response based on the reactivation of morphogenetic signaling mechanisms and a complex crosstalk among a multitude of cell types. The nature and mechanism of these exchanges determine the difference between healthy regenerative liver repair and pathologic repair. An orchestrated signaling among cell types directs mesenchymal cells to deposit a specific extracellular matrix with distinct physical and biochemical properties defined as portal fibrosis. Progression of fibrosis leads to vast architectural and vascular changes known as "liver cirrhosis." The signals regulating the ecology of this microenvironment are just beginning to be addressed. Contrary to the tumor microenvironment, immune modulation inside this "benign" microenvironment is scarcely known. One of the reasons for this is that both the ductular reaction and portal fibrosis have been primarily considered a manifestation of cholestatic liver disease, whereas this phenomenon is also present, albeit with distinctive features, in all chronic human liver diseases. Novel human-derived cellular models and progress in "omics" technologies are increasing our knowledge at a fast pace. Most importantly, this knowledge is on the edge of generating new diagnostic and therapeutic advances. Here, we will critically review the latest advances, in terms of mechanisms, pathophysiology, and treatment prospects. In addition, we will delineate future avenues of research, including innovative translational opportunities.

Therapeutic Potential of Foodborne Indole Derived from Chinese Stinky Tofu in Reducing Intestinal Inflammation and Enhancing Barrier Function to Mitigate Alcoholic Liver Injury.

Indole, a compound in Chinese stinky tofu (ST), acts as a ligand for the aryl hydrocarbon receptor (AHR). Despite extensive research on prebiotic compounds, indole's specific role in ST remains unexplored. This study used an ethanol gavage method to create an ALD (alcoholic liver disease) mouse model and investigate dietary indole's effects on the intestinal barrier. Our findings indicate that after 6 weeks of being fed ST, the indole present (2 mg/day) robustly activated the intestinal AHR, upregulating its target gene, CYP1A1 (cytochrome P450 1A1 enzyme). This activation significantly reduced intestinal permeability, mitigated alcohol-induced oxidative stress and inflammation, and restored intestinal barrier function. Consequently, the study demonstrates that foodborne indole substantially reduces alcohol absorption and lowers the expression levels of liver inflammation-related factors, thereby slowing the progression of ALD. These results highlight indole's therapeutic potential for treating ALD and its role in developing functional foods.

Insulin-like growth factor-binding protein 7 exacerbates inflammatory response and lipid metabolism imbalance in alcohol-associated liver disease.

Alcohol-associated liver disease(ALD), caused by excessive alcohol consumption, are often associated with inflammatory outbreaks and lipid deposition in the liver. The role of Insulin-like growth factor-binding protein 7 (IGFBP7), an important metabolic regulator, in ALD, its underlying regulatory mechanism, and its potential implication in anti-ALD therapies remain unknown. We investigated the effects of IGFBP7 on hepatic inflammation and lipid metabolism disruption in a mouse model of ALD. Mice were fed by chronic ethanol feeding plus a single binge of ethanol feeding(chronic-plus-single-binge model). In addition, ethanol exposure modeling studies were performed on cultured hepatocytes to verify molecular correlations. The results showed that IGFBP7 expression was significantly elevated in the livers of mice and hepatocytes after chronic ethanol exposure. Subsequently, the results of a study by specific knockout of IGFBP7(IGFBP7-cKO) in mouse hepatocytes and lentiviral silencing of IGFBP7 in vivo suggested that IGFBP7 deletion could improve liver function levels in alcohol-fed mice; It also attenuated the outbreak of hepatitis factor and the disorder of lipid metabolism in mice.Using RNA-seq sequencing of mouse liver tissue, we found that IGFBP7 affects several downstream metabolic signaling pathways, including PPAR, MAPK, FoxO, etc. Then, we used the PPARα plasmid in hepatocytes and discovered that overexpressing PPARα reversed the impact of IGFBP7 on lipid metabolism disorders in hepatocytes. In conclusion, IGFBP7 deficiency in alcohol-associated liver disease alleviates the decline in liver function and the imbalance of lipid metabolism in mice, attenuates the inflammatory outbreak, and affects a variety of downstream lipid metabolism factors by regulating PPARα. Hence, IGFBP7 may be an effective therapeutic target in the treatment of ALD.

Morphological Evolution of Atomic Layer Deposited Hafnium Oxide on Aligned Carbon Nanotube Arrays.

Microscopic study of the nucleation and growth of atomic layer deposition (ALD) dielectrics onto carbon nanotubes (CNTs) is an essential while challenging task toward high-performance devices. Here, we capture the morphological evolution and growth behaviors of ALD-HfO2 onto SiO2/Si-supported aligned CNT arrays (A-CNTs) under three ALD recipes via cross-sectional high-resolution scanning transmission electron microscopy. The HfO2 in ALD I (200 °C) preferentially nucleates on the SiO2 substrate in heterogeneous growth mode, resulting in films with considerable pinholes, while ALD II (90 °C) and III (90 °C and extra H2O presoak) exhibit homogeneous growth with nucleation on both SiO2 and CNTs, yielding uniform films. Arrangement defects in A-CNTs exacerbate nonuniformity of HfO2 and tube-tube separation plays deterministic roles affecting the HfO2-CNT interfacial morphology. Electrical measurements from A-CNTs metaloxide-semiconductor devices validate these findings. Our investigation contributes valuable insights for optimizing ALD processes for enhanced dielectric integration on A-CNTs in next-generation electronics.

Fabrication of anodic and atomic layer deposition-alumina coated titanium implants for effective osteointegration applications.

Biomimicking the chemical, mechanical, and topographical properties of bone on an implant model is crucial to obtain rapid and effective osteointegration, especially for the large-area fractures of the skeletal system. Titanium-based biomaterials are more frequently preferred in clinical use in such cases and coating these materials with oxide layers having chemical/nanotopographic properties to enhance osteointegration and implantation success rates has been studied for a long time. The objective of this study is to examine the high and rapid mineralization potential of anodized aluminum oxide (AAO) coated and atomic layer deposition (ALD)-alumina coated titanium substrates on large deformation areas with difficult spontaneous healing. AAO-coated titanium (AAO@Ti) substrates were fabricated via anodization technique in different electrolytes and their osteogenic potential was analyzed by comparing them to the bare titanium surface as a control. In order to investigate the effect of the ionic characters gained by the surfaces through anodization, the oxidized nanotopographic substrates were additionally coated with an ultrathin alumina layer via ALD (ALD@AAO@Ti), which is a sensitive and conformal coating vapor deposition technique. Besides, a bare titanium sample was also coated with pure alumina by ALD (ALD@Ti) to investigate the effect of nanoscale surface morphology. XPS analysis after ALD coating showed that the ionic character of each surface fabricated by anodization was successfully suppressed. In vitro studies demonstrated that, among the substrates investigated, the mineralization capacity of MG-63 osteosarcoma cells were highest when incubated on ALD-treated and bare AAO@Ti samples that were anodized in phosphoric acid (H3PO4_AAO@Ti and ALD@H3PO4_AAO@Ti). Mineralization on these substrates also increased consistently beginning from day 2 to day 21. Moreover, immunocytochemistry for osteopontin (OPN) demonstrated the highest expression for ALD@H3PO4_AAO@Ti, followed by the H3PO4_AAO@Ti sample. Consequently, it was observed that, although ALD treatment improves cellular characteristics on all samples, effective mineralization requires more than a simple ALD coating or the presence of a nanostructured topography. Overall, ALD@H3PO4_AAO@Ti substrates can be considered as an implant alternative with its enhanced osteogenic differentiation potential and rapid mineralization capacity.

Ultrasound Assessment of Sarcopenia in Alcoholic Liver Disease.

Malnutrition frequently affects patients with alcoholic liver disease (ALD), with important impacts on disease prognosis. Sarcopenia, the clinical phenotype of malnutrition characterized by skeletal muscle loss, is the major component responsible for adverse events in this population. The aim of this study is to assess the use of ultrasound (US) skeletal muscle performance in stratifying ALD disease severity. We recruited 43 patients with ALD and divided them into two groups: alcoholic hepatitis (AH) and alcoholic cirrhosis (AC). We evaluated disease-specific clinical and biological parameters and their relation to US Rectus Femoris muscle (RFM) measurements, including RFM thickness, stiffness (RFMS) and echogenicity (RFE). A thirty-seconds chairs stand test (30sCST) was used as the sarcopenia surrogate test. RMF thickness correlated with platelet count and serum albumin (p < 0.001). Both RFM and RFMS correlated with disease severity (p < 0.001) and 30sCST (p < 0.001, p = 0.002). Patients with AH had more severe US muscle abnormalities compared to AC (RFMS 1.78 m/s vs. 1.35 m/s, p = 0.001) and the highest prevalence of RFE (χ2 = 8.652, p = 0.003). Rectus Femoris US assessment could represent a reliable tool in the diagnosis and severity stratification of ALD-induced sarcopenia.

Key regulators of hepatic stellate cell activation in alcohol liver Disease: A comprehensive review.

Alcoholic liver disease (ALD) is a broad category of disorders that begin with liver injury, lead to liver fibrosis, and ultimately conclude in alcohol-induced liver cirrhosis, the most chronic and irreversible liver damage. Liver fibrosis (LF) is a common pathological characteristic observed in most chronic liver inflammatory conditions that involve prolonged inflammation. In this review, we have summarized ethanol-mediated hepatic stellate cell (HSCs) activation and its role in liver fibrosis progression. We highlight important molecular mechanisms that are modulated by ethanol, play a role in the activation of HSCs and the progression of liver fibrosis and identifying potential targets to ameliorate liver fibrosis.
