Charge-Assisted Ionic Hydrogen-Bonded Organic Frameworks: Designable and Stabilized Multifunctional Materials.

Hydrogen-bonded organic frameworks (HOFs) are a class of crystalline framework materials assembled by hydrogen bonds. HOFs have the advantages of high crystallinity, mild reaction conditions, good solution processability, and reproducibility. Coupled with the reversibility and flexibility of hydrogen bonds, HOFs can be assembled into a wide diversity of crystalline structures. Since the bonding energy of hydrogen bonds is lower than that of ligand and covalent bonds, the framework of HOFs is prone to collapse after desolventisation and the stability is not high, which limits the development and application of HOFs. In recent years, numerous stable and functional HOFs have been developed by π-π stacking, highly interpenetrated networks, charge-assisted, ligand-bond-assisted, molecular weaving, and covalent cross-linking. Charge-assisted ionic HOFs introduce electrostatic attraction into HOFs to improve stability while enriching structural diversity and functionality. In this paper, we review the development, the principles of rational design and assembly of charge-assisted ionic HOFs, and introduces the different building block construction modes of charge-assisted ionic HOFs. Highlight the applications of charge-assisted ionic HOFs in gas adsorption and separation, proton conduction, biological applications, etc., and prospects for the diverse design of charge-assisted ionic HOFs structures and multifunctional applications.

Sertraline-Induced Acute Pancreatitis: A Case Report and Literature Review.

Objective: Acute pancreatitis (AP) is a process of acute inflammation and cell damage of the pancreas. Gallstones and alcohol abuse are the most common cause for AP. Drug-induced pancreatitis (DIP), accounting for less than 3% of the AP, has become increasingly recognized as an additional and vitally important etiology of acute pancreatitis. Sertraline is an antidepressant of the selective serotonin reuptake inhibitor (SSRI)class that has a range of side effects even when used at the recommended dose. A recognized but rare association in teenagers is acute pancreatitis. The report is of a 15-year-old male teenager with a history of depression who developed acute pancreatitis following self-overdose of his sertraline prescription. Case Report: A 15-year-old teenager with an overdose of sertraline, which was the only medication he took, presented abdominal pain, nausea, and vomiting. The common causes of alcohol consumption, gallstones, biliary duct obstruction, malignancy, trauma, hypertriglyceridemia, and hypercalcemia were eliminated. The increased level of amylase and parenchymal edema of the pancreas revealed in computed tomography supported the diagnosis of acute pancreatitis. After discontinuation of the drug and conventional acute pancreatitis treatment, he recovered evenly. Conclusion: With the increasing use of antidepressant medications in patients of teenagers, this report is a reminder that clinicians should be aware of the association between SSRIs such as sertraline, particularly in cases of overdose, and the development of acute pancreatitis.

Cinchophen induces RPA1 related DNA damage and apoptosis to impair ENS development of zebrafish.

Nonsteroidal anti-inflammatory drugs (NSAIDs) have become contaminants widely distributed in the environment due to improper disposal and discharge. Previous study has found several components might involve in impairing enteric nervous system (ENS) development of zebrafish, including NSAIDs cinchophen. Deficient ENS development in fetal could lead to Hirschsprung disease (HSCR), a congenital neurocristopathy characterized by absence of enteric neurons in hindgut. However, the intrinsic mechanism of neurotoxicity of cinchophen is unclear. We confirmed that cinchophen could impair ENS development of zebrafish and transcriptome sequencing revealed that disfunction of Replication protein A1 (RPA1), which is involved in DNA replication and repairment, might be relevant to the neurotoxicity effects induced by cinchophen. Based on previous data of single cell RNA sequencing (scRNA-seq) of zebrafish gut cells, we observed that rpa1 mainly expressed in proliferating, differentiating ENS cells and neural crest progenitors. Interestingly, cinchophen induced apoptosis and impaired proliferation. Furthermore, cinchophen caused DNA damage and abnormal activation of ataxia telangiectasia mutated/ Rad3 related (ATM/ATR) and checkpoint kinase 2 (CHK2). Finally, molecular docking indicated cinchophen could bind and antagonize RPA1 more effectively. Our study might provide a better understanding and draw more attention to the role of environmental factors in the pathogenesis of HSCR. And the mechanism of cinchophen neurotoxicity would give theoretical guidance for clinical pharmacy.

Water-Induced Single-Crystal to Single-Crystal Transformation of Ionic Hydrogen-Bonded Organic Frameworks with Enhanced Proton Conductivity.

Two ionic hydrogen-bonded organic frameworks (iHOF-10, iHOF-11) were prepared using 1,1'-diamino-4,4'-bipyridine diiodide (Dbpy ⋅ 2I) and tetrakis(4-sulfophenyl)ethylene (H4 TPE). With increasing RH and temperature, water molecules induce single crystal to single crystal (SCSC) transformation of iHOF-10, resulting in the formation of iHOF-11. At 90 °C, 98 % RH, the proton conductivity of iHOF-11 (7.03×10-3  S cm-1 ) is 2.09 times higher than iHOF-10 (3.37×10-3  S cm-1 ). At 50 °C, 98 % RH, iHOF-11 (9.49×10-4  S cm-1 ) is 19.06 times higher than iHOF-10 (4.98×10-5  S cm-1 ). The proton conductivity shows water molecules enter the crystal and induce crystal transformation and reorganization of the hydrogen bonding structure, thus increasing the proton conductivity and stability.

Atomistic origin of kinetics in hydrated aluminosilicate gels upon precipitation.

Calcium-alumino-silicate-hydrate (CaO-Al2O3-SiO2-H2O, or C-A-S-H) gel, which is the binding phase of cement-based materials, greatly influences concrete mechanical properties and durability. However, the atomic-scale kinetics of the aluminosilicate network condensation remains puzzling. Here, based on reactive molecular dynamics simulations of C-A-S-H systems formation with varying Al/Ca molar ratios, we study the kinetic mechanism of the hydrated aluminosilicate gels upon precipitation. We show that the condensation activation energy decreases with the Al/Ca molar ratio, which suggests that the concentration of the Al polytopes has a great effect on controlling the kinetics of the gelation reaction. Significantly, we demonstrate that 5-fold Al atoms are mainly forming at high Al/Ca molar ratios since there are insufficient hydrogen cations or extra calcium cations to compensate the negatively charged Al polytopes at high Al/Ca molar ratios during accelerated aging.

Abnormally elevated expression of ACTA2 of circular smooth muscle leads to hyperactive contraction in aganglionic segments of HSCR.

BACKGROUND: Actin Alpha 2 (ACTA2) is expressed in intestinal smooth muscle cells (iSMCs) and is associated with contractility. Hirschsprung disease (HSCR), one of the most common digested tract malformations, shows peristaltic dysfunction and spasm smooth muscles. The arrangement of the circular and longitudinal smooth muscle (SM) of the aganglionic segments is disorganized. Does ACTA2, as a marker of iSMCs, exhibit abnormal expression in aganglionic segments? Does the ACTA2 expression level affect the contraction function of iSMCs? What are the spatiotemporal expression trends of ACTA2 during different developmental stages of the colon? METHODS: Immunohistochemical staining was used to detect the expression of ACTA2 in iSMCs of children with HSCR and Ednrb-/- mice, and the small interfering RNAs (siRNAs) knockdown technique was employed to investigate how Acta2 affected the systolic function of iSMCs. Additionally, Ednrb-/- mice were used to explore the changes in the expression level of iSMCs ACTA2 at different developmental stages. RESULTS: The expression of ACTA2 is higher in circular SM in the aganglionic segments of HSCR patients and Ednrb-/- mice than in normal control children and mice. Down regulation of Acta2 weakens the contraction ability of intestinal smooth muscle cells. Abnormally elevated expression of ACTA2 of circular smooth muscle occurs since embryonic day 15.5 (E15.5d) in aganglionic segments of Ednrb-/- mice. CONCLUSIONS: Abnormally elevated expression of ACTA2 in the circular SM leads to hyperactive contraction, which may cause the spasm of aganglionic segments in HSCR.

Activated M1 macrophages suppress c-kit expression via TNF-α-mediated upregulation of miR-222 in Neonatal Necrotizing Enterocolitis.

BACKGROUND: Activation of intestinal macrophages is implicated in the pathogenesis of neonatal necrotizing enterocolitis (NEC), yet its precise mechanisms remain unclear. OBJECTIVE: The purpose of this study is to investigate the role of macrophages and TNF-α via an inflammatory MicroRNA in NEC. MATERIALS AND METHODS: Immunofluorescence (IF) staining of CD68, iNOS, and Arg-1 was employed to identify phenotypes of macrophage in the intestines of NEC infants and NEC mice. Expression of TNF-α, c-kit, and miR-222 was evaluated by qRT-PCR, Western blot, and immunochemical staining from the tissue samples. RESULTS: Large number of M1 macrophage infiltration was found in the NEC intestines. Expression of CD68, iNOS, and TNF-α were significantly increased, while c-kit was decreased distinctly in the NEC group. In the early phase of NEC mouse model, inhibition of M1 macrophages reduced the incidence of NEC and intestinal inflammation. We found that TNF-α upregulated the expression of miRNA-222 and inhibited the expression of c-kit. Conversely, such decrease of c-kit expression could be reversed by miR-222 antagonists. Furtherly, dual-luciferase assay confirmed that c-kit can be inhibited by miR-222 directly. CONCLUSION: Macrophages activation in NEC intestine results in an increased inflammatory response and TNF-α production, accompanied with miR-222 upregulation and c-kit suppression. Modulations of M1 macrophages, TNF-α or miR-222 may be potential therapeutic targets for NEC treatment.

Materials chemistry for rechargeable zinc-ion batteries.

Rechargeable zinc-ion batteries (ZIBs) are promising for large scale energy storage and portable electronic applications due to their low cost, material abundance, high safety, acceptable energy density and environmental friendliness. This tutorial review presents an introduction to the fundamentals, challenges, recent advances and prospects related to ZIBs. Firstly, the intrinsic chemical properties, challenges and strategies of metallic zinc anodes are underscored. Then, the multiple types of cathode materials are classified and comparatively discussed in terms of their structural and electrochemical properties, issues and remedies. Specific attention is paid to the mechanistic understanding and structural transformation of cathode materials based on Zn ion-(de)intercalation chemistry. After that, the widely investigated electrolytes are elaborated by discussing their effect on Zn plating/stripping behaviours, reaction kinetics, electrode/electrolyte interface chemistries, and cell performances. Finally, the remaining challenges and future perspectives are outlined for the development of ZIBs.

Dual roles of commensal bacteria after intestinal ischemia and reperfusion.

PURPOSE: The roles of commensal bacteria after intestinal ischemia and reperfusion (IIR) are unclear. In current study, we aim to investigate the effects and underlying mechanisms of commensal bacteria in injury and epithelial restitution after IIR. METHODS: Commensal gut bacteria were deleted by broad-spectrum antibiotics in mice. IIR was induced by clamping superior mesenteric artery. Intestinal injury, permeability, epithelial proliferation, and proinflammatory activity of mesenteric lymph were investigated. RESULTS: Commensals deletion improved mice survival in the early phase, but failed to improve the overall survival at 96 h after IIR. Commensals deletion reduced proliferation of intestinal epithelial cells (IEC) and augmented proinflammatory activity of mesenteric lymph after IIR. Lipopolysaccharides (LPS) supplement promoted IEC proliferation and improved survival in mice with commensals deletion after IIR. LPS induced production of prostaglandin E2 (PGE2) in mucosa via toll-like receptor 4-NFκB-cyclooxygenase 2 pathway. PGE2 enhanced IEC proliferation in vivo, which was preceded by activation of Akt and extracellular signal-regulated kinase (ERK) 1/2. Blocking of EGFR, PI3K/Akt activity abolished LPS-induced IEC proliferation. CONCLUSIONS: Commensal bacteria are essential for epithelial restitution after IIR, which enhance IEC proliferation via induction of PGE2.

Phosphorylation of CDC25C by AMP-activated protein kinase mediates a metabolic checkpoint during cell-cycle G2/M-phase transition.

From unicellular to multicellular organisms, cell-cycle progression is tightly coupled to biosynthetic and bioenergetic demands. Accumulating evidence has demonstrated the G1/S-phase transition as a key checkpoint where cells respond to their metabolic status and commit to replicating the genome. However, the mechanism underlying the coordination of metabolism and the G2/M-phase transition in mammalian cells remains unclear. Here, we show that the activation of AMP-activated protein kinase (AMPK), a highly conserved cellular energy sensor, significantly delays mitosis entry. The cell-cycle G2/M-phase transition is controlled by mitotic cyclin-dependent kinase complex (CDC2-cyclin B), which is inactivated by WEE1 family protein kinases and activated by the opposing phosphatase CDC25C. AMPK directly phosphorylates CDC25C on serine 216, a well-conserved inhibitory phosphorylation event, which has been shown to mediate DNA damage-induced G2-phase arrest. The acute induction of CDC25C or suppression of WEE1 partially restores mitosis entry in the context of AMPK activation. These findings suggest that AMPK-dependent phosphorylation of CDC25C orchestrates a metabolic checkpoint for the cell-cycle G2/M-phase transition.

Gastroduodenal perforation in the pediatric population: a retrospective analysis of 20 cases.

OBJECTIVE: The aim of this study was to investigate the pathogenesis, symptoms and individualized surgical management in pediatrics with gastroduodenal perforation (GDP). METHODS: Patients diagnosed with GDP from January 2013 to December 2016 in our hospital were collected and divided into gastric perforation (GP) group and duodenal perforation (DP) group. Demographics, clinical events, etiological factors, symptoms, the time from symptom onset to operation, intraoperative findings and surgical procedures were analyzed. Follow-ups including ulcer, perforations occurrence, and digestive symptoms were carried out by out-patient review or telephones. RESULTS: A total of 20 patients aged from 3 months to 14 years were enrolled in this study. The average age, main clinical presentations, size of perforations and operating time between two groups had no difference. The male to female ratio in DP group was higher than GP (P < 0.05). The high risk factor for DP was the use of dexamethasone, and for GP was HP infection. The most common site of perforation in DP group was duodenal bulb, and in GP group was pylorus area. Simple suture is the main management for both DP and GP, but distal gastrectomy combined with gastrojejunal Roux-en-Y anastomosis may be an alternative procedure for large perforation with diameter > 2 cm. The length of hospital days in GP group is shorter than DP group (P < 0.05). For follow-up, no patients had digestive symptoms. CONCLUSIONS: The general condition had no difference between GP and DP patients. But the risk factors and surgical repair differ depending on the patient's fundamental illness and the complexity of the perforation.

Diagnostic value of the preoperatively detected radiological transition zone in Hirschsprung's disease.

BACKGROUND AND OBJECTIVE: The cardinal diagnostic sign of congenital aganglionic megacolon, or Hirschsprung's disease (HD), is an aganglionic segment of the distal colon or rectum. To determine the surgical planning of a radiological transition zone (TZ) in HD, this study investigated the association between a radiological TZ and the bowel resection length. METHODS: A prospective observational study was conducted in children (n = 192) with suspected HD determined by radiological TZ on contrast barium enema, and who underwent pull-through operations. The bowel resection length was ≥10 cm above the proximal radiological TZ levels and confirmed by intraoperative frozen sections. In the contrast enema, the presence and level of a radiological TZ were recorded. Correlation of the TZ features with ganglion cells assessed by immunostaining of neuronal nuclei (NeuN) and the odds ratio were calculated. RESULTS: The sensitivity and specificity for diagnosing HD by the presence of a radiological TZ were 86.9 and 92.1%, respectively; Youden's index was 79.0%. The positive and negative predictive values were 91.7 and 87.6%. The kappa value indicating an association between TZ and HD was 0.776 (P < 0.05). The correlation rate between a radiological TZ and the pathological results was 88.5% in the rectosigmoid colon and 44.4% in the descending colon, and was higher in children older than 3 months (85.3%) than in infants (69.0%). CONCLUSION: A preoperatively determined radiological TZ has potential value to identify the length of resected bowel in patients with HD, and it also has a high predictive value for diagnosis of HD.

Pathological changes of interstitial cells of Cajal and ganglion cells in the segment of resected bowel in Hirschsprung's disease.

OBJECTIVES: This study was conducted to investigate the pathological changes which occur in interstitial cells of Cajal (ICCs) and ganglion cells found in segments of resected bowel obtained from patients with Hirschsprung's disease (HD), as well as to explore the benefits of using a contrast enema (CE) with 24-h delayed X-ray films to predict the length of resected bowel. METHODS: We performed a retrospective analysis of 58 children with HD who had undergone the pull-through procedure. After each operation, the ICCs and ganglion cells present in the proximal ends of the barium residue (Level A) and resected proximal bowel segment (Level B) were analyzed using immunohistochemical staining methods. Each patient was followed up for 1 year to record their stool frequency, defecation control ability, and post-surgical complications which may have occurred. RESULTS: Immunohistochemical staining detected fewer ICCs in Level A than in Level B (p < 0.05). However, the density of ganglion cells in the two levels was not significantly different (p > 0.05). One patient had anastomotic stricture, and five patients suffered from enterocolitis. CONCLUSIONS: The density of ICCs was significantly lower in the bowel segments that displayed barium retention. A CE may be a valuable tool for predicting the length of bowel resection in patients with HD.

CD8+ T lymphocyte response against extrahepatic biliary epithelium is activated by epitopes within NSP4 in experimental biliary atresia.

Interferon (IFN)-γ-driven and CD8+ T cell-dependent inflammatory injury to extrahepatic biliary epithelium (EHBE) is likely to be involved in the development of biliary atresia (BA). We previously showed that viral protein NSP4 is the pathogenic immunogen that causes biliary injury in BA. In this study, NSP4 or four synthetic NSP4 (NSP4(157-170), NSP4(144-152), NSP4(93-110), NSP4(24-32)) identified by computer analysis as candidate CD8+ T cell epitopes were injected into neonatal mice. The pathogenic NSP4 epitopes were confirmed by studying extrahepatic bile duct injury, IFN-γ release and CD8+ T cell response against EHBE. The results revealed, at 7 days postinjection, inoculation of glutathione S-transferase (GST)-NSP4 caused EHBE injury and BA in neonatal mice. At 7 or 14 days postinject, inoculation of GST-NSP4, NSP4(144-152), or NSP4(157-170) increased IFN-γ release by CD8+ T cells, elevated the population of hepatic memory CD8+ T cells, and augmented cytotoxicity of CD8+ T cells to rhesus rotavirus (RRV)-infected or naive EHBE cells. Furthermore, depletion of CD8+ T cells in mice abrogated the elevation of GST-NSP4-induced serum IFN-γ. Lastly, parenteral immunization of mouse dams with GST-NSP4, NSP4(144-152), or NSP4(157-170) decreased the incidence of RRV-induced BA in their offspring. Overall, this study reports the CD8+ T cell response against EHBE is activated by epitopes within rotavirus NSP4 in experimental BA. Neonatal passive immunization by maternal vaccination against NSP4(144-152) or NSP4(157-170) is effective in protecting neonates from developing RRV-related BA.

Effects of lipopolysaccharide-induced inflammation on the interstitial cells of Cajal.

Interstitial cells of Cajal (ICC) have recently been found to display phenotypic changes. The present study is designed to determine whether phenotypic changes occur in ICC associated with an inflammatory microenvironment and whether the ICC phenotype could be recovered after the discontinuation of inflammatory stimuli. Immunohistochemistry studies revealed that the functional ICC marker, c-kit, was markedly reduced in patients with Hirschsprung's disease (n = 34) compared with controls (n = 12), whereas another marker of ICC, CD34, was not altered significantly. Compared with the vehicle group (n = 6), intraperitoneal injection of lipopolysaccharide (LPS; 1.5 mg/kg) in mice (n = 6) significantly induced plasma tumor necrosis factor-alpha (TNF-α) levels as determined by enzyme-linked immunosorbent assay. Western blot and real-time polymerase chain reaction assessment further showed that LPS injection markedly suppressed intestinal c-kit protein and mRNA expression, which could be blocked by Toll-like receptor 4 (TLR4) deficiency (n = 6) rather than TLR2 deficiency (n = 6) and had no effects on CD34. Compared with the vehicle group (n = 6), intraperitoneal TNF-α (30 µg/kg) administration (n = 6) also significantly reduced intestinal c-kit protein and mRNA levels but not CD34 levels. However, the reduction of c-kit induced by TNF-α injection was not suppressed by TLR4 deficiency (n = 6). Intestinal c-kit protein and mRNA levels were markedly restored after the discontinuation of TNF-α administration for 7 days. Moreover, immunofluorescence analysis of primary ICC further confirmed that exposure to TNF-α for 24 h suppressed c-kit expression, which could be restored after discontinuation of TNF-α exposure. CD34 expression was not altered upon exposure to TNF-α. Thus, phenotypic changes in ICC occur in an inflammatory microenvironment in the gut and LPS, TLR4 and TNFα are crucial to this process.

Glycerol kinase enzyme is a prognostic predictor in esophageal carcinoma and is associated with immune cell infiltration.

The influence of lipid metabolism on tumorigenesis and progression has garnered significant attention. However, the role of Glycerol Kinase (GK), a key enzyme in glycerol metabolism, in Esophageal Carcinoma (ESCA) remains unclear. To further elucidate the relationship between GK and ESCA, we investigated GK expression levels using database information. Controlled studies employing immunohistochemistry were conducted on clinical ESCA tumor samples and normal specimens, confirming GK's elevated expression in ESCA. Analysis of The Cancer Genome Atlas (TCGA) data via Kaplan-Meier (KM) survival plots revealed that increased GK expression correlates with poorer ESCA patient outcomes, particularly in overall survival (OS) and disease-specific survival (DSS). Multiple regression analysis indicated that elevated GK expression is an independent risk factor affecting ESCA prognosis. Statistical analysis of prognostic data from clinical samples further corroborated this finding. Moreover, there appears to be a significant correlation between GK expression and immune infiltration, specifically involving certain T and B lymphocytes. In conclusion, elevated GK expression in ESCA is strongly linked to poor prognosis and increased immune cell infiltration, highlighting its potential as an independent prognostic biomarker and a viable therapeutic target.

Electrical acupoint stimulation for the treatment of chemotherapy-induced nausea and vomiting: A systematic review and meta-analysis.

Background: Chemotherapy-induced nausea and vomiting (CINV) is the most common adverse effect of chemotherapy and affects the continuation of chemotherapy in cancer patients. Electrical acupoint stimulation (EAS), which includes electroacupuncture and transcutaneous electrical stimulation (TES), has been used to treat CINV. This meta-analysis aimed to evaluate the efficacy of EAS in the treatment of CINV. Methods: Randomized controlled trials (RCTs) of EAS for CINV retrieved form five key databases. Two researchers independently performed article screening, data extraction and data integration. The Cochrane Collaboration's tool for assessing risk of bias was used to assesse the methodological quality according to Cochrane Handbook for Systematic Reviews of Interventions. RevMan 5.4 was used to perform analyses. Results: 10 RCTs with a total of 950 participants were included. The results showed that there was no significant difference between EAS compared to sham EAS in terms of increasing the rate of complete control of CINV and decreasing the overall incidence of CINV [RR = 1.26, 95 % CI (0.96, 1.66), P = 0.95; RR = 1.16, 95 % CI (0.97, 1.40), p = 0.71]. In terms of CINV severity, EAS reduced the occurrence of moderate-to-severe CINV [RR = 0.60, 95 % CI (0.38, 0.94), P = 0.03; RR = 0.50, 95 % CI (0.33, 0.76), P = 0.001]. Conclusion: EAS could improve moderate-to-severe CINV. However, EAS did not show a significant difference in reducing overall incidence and improving complete control rates compared with sham EAS. Due to limitations in the quality of the included articles, the available studies are insufficient to have sufficient evidence to confirm the efficacy of EAS for CINV. Validation with rigorously designed, large-sample, high-quality clinical trial studies may also be needed.

Alanine aminotransferase as a risk marker for new-onset metabolic dysfunction-associated fatty liver disease.

In this editorial, we comment on the article by Chen et al. Metabolic dysfunction-associated fatty liver disease (MAFLD) is a global public health burden whose incidence has risen concurrently with overweight and obesity. Given its detrimental health impact, early identification of at-risk individuals is crucial. MAFLD diagnosis is based on evidence of hepatic steatosis indicated by liver biopsy, imaging, or blood biomarkers, and one of the following conditions: Overweight/ obesity, type 2 diabetes mellitus, or metabolic dysregulation. However, in large-scale epidemiological studies, liver biopsies are not feasible. The application of techniques such as ultrasonography, computed tomography, magnetic resonance imaging, and magnetic resonance spectroscopy is restricted by their limited sensitivity, low effectiveness, high costs, and need for specialized software. Blood biomarkers offer several advantages, particularly in large-scale epidemiological studies or clinical scenarios where traditional imaging techniques are impractical. Analysis of cumulative effects of excess high-normal blood alanine aminotransferase (ALT) levels of blood ALT levels could facilitate identification of at-risk patients who might not be detected through conventional imaging methods. Accordingly, investigating the utility of blood biomarkers in MAFLD should enhance early detection and monitoring, enabling timely intervention and management and improving patient outcomes.
