Early chronic pancreatitis (ECP) represents a potentially reversible stage in the natural history of chronic pancreatic disease. Timely diagnosis of ECP offers a possibility for intervention, yet its diagnosis remains challenging due to nonspecific symptoms, lack of standardized criteria, and the limited diagnostic sensitivity of conventional tools. This review aims to synthesize recent advancements in the understanding, detection, and management of ECP, with a focus on innovation in imaging techniques and biomarker profiling. The goal is to facilitate earlier diagnosis and more effective patient stratification. We reviewed the literature from the past five years, including original studies, meta-analyses, and expert consensus statements, to address the current evidence across genetic, inflammatory, imaging, and biochemical domains relevant to ECP. Endoscopic ultrasound and advanced magnetic resonance techniques offer high sensitivity in detecting early parenchymal changes, although inter-observer variability and lack of standardization persist. Biomarker discovery has focused on inflammatory (IL-6, sCD163), fibrotic (TGF-β1, TIMP-1), and oxidative markers, as well as novel candidates like microRNAs. Genetic predisposition (PRSS1, SPINK1, CTRC, CPA1, CLDN2) significantly influences disease onset and progression and could enable selection of high-risk individuals. Therefore, diagnosing ECP should involve a multidisciplinary precision-based approach integrating clinical, radiologic, molecular, serologic, and genetic data for individualized risk stratification.

Objectives: Adenocarcinoma presenting as ground-glass opacities (GGOs) often corresponds to lepidic growth tumor and is associated with less invasive behavior and a good prognosis. The aim of this study is to investigate the correlation between radiological and pathological findings of GGO and their relationship with lung cancer-specific survival (LCSS) and incidence of relapses to better define their surgical management. Methods: One hundred seventy-two patients underwent lung resection for adenocarcinoma presenting as pure GGO or partial solid GGO at CT scan. Based on consolidation-to-tumor ratio (CTR) at CT scan, patients were categorized into two groups: pure GGO (CTR 0) and partial solid GGO (CTR ≤ 0.5, 0.5 < CTR ≤ 0.75, and 0.75 < CTR ≤ 1.0). Histological analysis confirmed diagnosis, invasiveness, and grading. Results: Comparing the group with pure GGO (n = 90; 52.3%) and the groups with partial solid GGO (n = 82; 47.7%), invasive adenocarcinoma was significantly more frequent in the last one (p = 0.0006). In the partial solid GGO group, the majority of tumors were G2, and the percentage of G3 tumors increased with the CTR increasing (p < 0.0001). Twenty-one (12.2%) patients experienced disease recurrence: 16 (9.3%) were invasive adenocarcinoma (IA), and 5 (2.9%) were minimally invasive adenocarcinomas (MIA); radiologically, 13 (7.5%) were pure GGO, and 8 (4.6%) had a solid component. At multivariate analysis, relapse was associated with age > 60 (p = 0.037), clinical stage ≥ cIB (p = 0.002), and sublobar resection (p = 0.005). Conclusions: Pure GGO was associated with minor invasiveness, with prognosis dependent on age, clinical stage, and type of surgery (sublobar vs. lobar resection). Sublobar resections had a higher recurrence risk. Full article

Virgin coconut oil (VCO) has emerged as a functional food oil with considerable health benefits and wide applications in the food, pharmaceutical, and cosmetic industries due to its resident bioactive compounds, including lauric acid (LA). LA is the most abundant saturated medium-chain fatty acid in VCO and has been associated with several pharmacological activities. The literatures show the pharmacological effects of VCO and LA on chronic pathologies, infectious diseases, and metabolic disorders. A robust body of evidence shows that LA and other phenolic compounds are responsible for the VCO protection against toxicities and pharmacological efficacies. This review elucidates the anticancer mechanisms of VCO/LA and their modulation of the chemotherapy-induced side effect toxicity. VCO, LA, and their nanomaterial/encapsulated derivatives promote ROS generation, antiproliferation, apoptosis, cell cycle arrest, the inhibition of metastasis, and the modulation of cancer-related signaling pathways for cancer cell death in vivo and in vitro. VCO mitigates oxidative inflammation and apoptosis to block the underlying mechanisms of the side effect toxicity of chemotherapy. However, the possible beneficial effect of LA on the toxicity of chemotherapy is currently unknown. The available evidence emphasizes the anticancer effect and mechanism of VCO and LA, and the VCO potential to combat adverse side effects of chemotherapy. Thus, VCO and LA are potential adjuvant therapeutic agents in the management of various cancers. Nevertheless, future studies should be targeted at elucidating cancer-related molecular mechanisms to bridge the gap in knowledge. Full article

Lychee (Lychee chinensis Sonn.) is a tropical fruit highly appreciated for its vivid red color, sweet flavor, and nutritional properties. However, it is highly perishable, with postharvest losses often due to oxidative browning and dehydration. This study evaluated the organic olive oil coating (OC), a natural lipidic system with the potential to act as a precursor for organogel development, combined with polyamide/polyethylene (PA/PE) packaging under passive modified atmosphere. Fruits were harvested at commercial maturity and divided into two groups: OC-treated and untreated control (CTR). Both groups were stored at 5 ± 1 °C and 90 ± 5% relative humidity and analyzed on days 0, 3, 6, and 9. The OC-treated fruits showed significantly better retention of physical, chemical, microbiological, and sensory qualities. The coating reduced oxidative stress and enzymatic browning, preserving color and firmness. The PA/PE packaging regulated gas exchange, lowering oxygen levels and delaying respiration and ripening. As a result, OC fruits had lower weight loss, a slower increase in browning index and maturity index, and better visual and sensory scores than the CTR group. This dual strategy proved effective in extending shelf life while maintaining the fruit’s appearance, flavor, and nutritional value. It represents a sustainable and natural approach to enhancing the postharvest stability of lychee. Full article

Maternal obesity programs the fetus for increased risk of chronic disease development in early life and adulthood. We hypothesized that maternal nutrient excess leads to fetal inflammation and impairs offspring skeletal muscle mitochondrial biogenesis in non-human primates. At least 12 months before pregnancy, female baboons were fed a normal chow (CTR, 12% energy fat) or a maternal nutrient excess (MNE, 45% energy fat, and ad libitum fructose sodas) diet, with the latter to induce obesity. After 165 days of gestation (0.9 G), offspring baboons were delivered by cesarean section, and the soleus muscle was collected (CTR n = 16, MNE n = 5). At conception, MNE mothers presented increased body fat and weighed more than controls. The soleus muscle of MNE fetuses exhibited increased levels of stress signaling associated with inflammation (TLR4, TNFα, NF-kB p65, and p38), concomitant with reduced expression of key regulators of mitochondrial biogenesis, including PGC1α, both at the protein and transcript levels, as well as downregulation of PPARGC1B, PPARA, PPARB, CREB1, NOS3, SIRT1, SIRT3. Decreased transcript levels of NRF1 were observed alongside diminished mitochondrial DNA copy number, mitochondrial fusion elements (MFN1, MFN2), cytochrome C protein levels, and cytochrome C oxidase subunits I and II transcripts (cox1 and cox2). MNE coupled to MO-induced stress signaling in fetal baboon soleus muscle is associated with impaired mitochondrial biogenesis and lower mitochondrial content, resembling the changes observed in metabolic dysfunctions, such as diabetes. The observed fetal alterations may have important implications for postnatal development and metabolism, potentially increasing the risk of early-onset metabolic disorders and other non-communicable diseases.

Background: Epiretinal membrane (ERM) and proliferative diabetic retinopathy (PDR) belong to the group of vitreoretinal diseases, characterized by impairments at both the retina and the vitreous. The non-diabetic and diabetic forms of ERM (no-dERM and dERM) as well as the PDR are caused by microvascular disorder, which frequently occurs in association with inflammation and oxidative stress. To better characterize no-dERM, dERM, and PDR at the biomolecular level, we compared the expression of inflammatory, oxidative, lipidic peroxidation products, and complement receptors. Methods: Twenty-seven ocular fluids from patients who underwent phaco-vitrectomy were categorized as no-dERM (9, 4M/5F; 70.4 ± 6.4), dERM (6, 3M/3F; 73.2 ± 4.9), and PDR (6, 5M/1F; 63.7 ± 7.4). Six cataracts (CTR; 3M/3F; 77.7 ± 9.0) were collected for internal control of aqueous cells. Results: In aqueous cells, p65NFkB, iNOS, Nox1/Nox4, and Nrf2 were significantly upregulated, and Keap1 was downregulated in dERM compared with PDR and no-dERM. In aqueous cells, a significant upregulation for C3aR1mRNA, C5aR1mRNA, and CFHmRNA were observed in dERM. In vitreous, C3a, C5b9, and MDA levels were significantly increased in dERM compared with PDR and no-dERM. Conclusions: Inflammatory and ROS products, as well as C3aR1/C5aR1 and soluble MDA, appear of great interest, as their expression in aqueous and vitreous might have potential prognostic and therapeutic values.

This study evaluated the therapeutic potential of 70% ethanol extracts from six medicinal plants (Chenopodium album, Cassia tora, Cudrania tricuspidata, Dioscorea polystachya, Lonicera japonica, Solidago virgaurea subsp. gigantea) through their antibacterial, antioxidant, cytotoxic, and immunomodulatory activities, targeting applications in aquaculture. All extracts exhibited potent antibacterial activity (MIC ≤ 10 μg/mL) against Aeromonas spp. and Photobacterium damselae subsp. damselae, but limited efficacy against Streptococcus parauberis. C. tricuspidata (CTR) and C. tora (CTO) demonstrated superior antioxidant activity (IC₅₀ = 1292 μg/mL and IC₅₀ = 227 μg/mL, respectively), correlating with high polyphenol content (1498 and 1409 mg GAE/g). CTR displayed significant concentration-dependent cytotoxicity (IC₅₀ = 904.2 μg/mL), while C. album (CA) promoted cell proliferation (132.3% viability). In LPS-stimulated CHSE-214 cells, D. polystachya (DP) induced the highest IL-8 expression (207-fold), followed by Chenopodium album (CA) (194-fold IL-8, 49-fold TNF-α) and CTR (245-fold RIPK2), activating NF-κB, MAPK, and NOD-like receptor pathways critical for teleost immunity. Lonicera japonica (LJ) suppressed TNF-α (0.4-fold) and IRF1 (0.3-fold), indicating anti-inflammatory potential, while S. virgaurea subsp. gigantea (SV) showed biphasic TNF-α modulation (79-fold at 10 μg/mL, 5-fold at 100 μg/mL). These diverse bioactivities, particularly the robust immunomodulatory effects, highlight the promise of these extracts as natural therapeutic agents for fish health management in aquaculture.

Background/Objectives: Postoperative septic events represent a major paramevter of morbidity and mortality following major abdominal surgery. Early identification and prediction can have a major impact on clinical management, reduction of hospitalization costs, and restriction of irrational use of antibiotics. For this purpose, two novel biomarkers (C-reactive protein to albumin or transferrin ratios, CAR and CTR, respectively) were evaluated. Methods: A combined retrospective and prospective study of 200 patients who underwent elective or emergency open abdominal surgery was performed. Patient demographics, emergency status, type of operation, and white blood cell (WBC) count, serum albumin (ALB), serum transferrin (TRF), and CAR-CTR were evaluated. Multiple-way ANOVA was utilized. Multiparametric and logistic regression analyses were performed for each confounder. Receiver operating characteristic (ROC) curve analysis and corresponding diagrams of sensitivity vs 1-specificity were applied for CAR and CTR in postoperative days 2 and 3. Results: WBC number had no predictive significance in septic event identification (p = 0.461), while postoperative CAR, CTR, ALB, TRF, BMI, and emergency status were significantly correlated (p < 0.001). At postoperative day 2, a CTR of 9.48 and a CAR of 4.14 have 75.9% and 70.4% specificity and 86% and 87.7% sensitivity, respectively. At postoperative day 3, a CTR of 8.89 and a CAR of 4.25 have 74.1% and 79.6% specificity and 87.7% and 86% sensitivity, respectively. Conclusions: Early identification of postoperative septic events may significantly facilitate decreasing postoperative morbidity and mortality. Both CAR and CTR displayed significant predictive ability in identifying patients prone to developing postoperative septic events, highlighting their significance in everyday clinical practice.

Background/Objectives: Chronic pancreatitis (CP) is a progressive inflammatory condition of the pancreas that leads to irreversible changes in pancreatic structure. The pancreatic α and β cells secrete hormones such as insulin and glucagon into the bloodstream. The pancreatic acinar cells secrete digestive enzymes that break down macromolecules. When these digestive enzymes do not function properly, maldigestion, malabsorption, and malnutrition may result. Presented here is a case study of an individual newly diagnosed with chronic pancreatitis, along with a genetic analysis of his son and an in-silico analysis of two of the variant proteins. Methods: This study was conducted using human subjects, namely, the proband (father) and his son. Medical genetic testing of the proband (father) identified the presence of two variants in the cystic fibrosis transmembrane receptor gene (CFTR): variant rs213950, resulting in a single amino acid change (p. Val470Met), and variant rs74767530, a nonsense variant (Arg1162Ter) with known pathogenicity for cystic fibrosis. Medical testing also revealed an additional missense variant, rs515726209 (Ala73Thr), in the CTRC gene. Cheek cell DNA was collected from both the proband and his son to determine the inheritance pattern and identify any additional variants. A variant in the human leukocyte antigen (rs7454108), which results in the HLA-DQ8 haplotype, was examined in both the proband and his son due to its known association with autoimmune disease, a condition also linked to chronic pancreatitis. In silico tools were subsequently used to examine the impact of the identified variants on protein function. Results: Heterozygosity for all variants originally identified through medical genetic testing was confirmed in the proband and was absent in the son. Both the proband and his son were found to have the DRB1*0301 (common) haplotype for the HLA locus. However, the proband was also found to carry a linked noncoding variant, rs2647088, which was absent in the son. In silico analysis of variant rs213950 (Val470Met) in CFTR and rs515726209 (Ala73Thr) in CTRC revealed distinct changes in predicted ligand binding for both proteins, which may affect protein function and contribute to the development of CP. Conclusions: This case study of a proband and his son provides additional evidence for a polygenic inheritance pattern in CP. The results also highlight new information on the role of the variants on protein function, suggesting additional testing of ligand binding for these variants should be done to confirm the functional impairments.

Background/Objectives: Traditional diet management for type 2 diabetes (T2DM) is often complex and effortful to sustain. Nudging offers low-effort and automatic approaches to dietary behaviour change yet remains underexplored in T2DM. This study evaluated the independent and combined 6-month effects of nudging education (NE) and nudging tableware (NT) on HbA1c, along with other secondary health outcomes, among adults with T2DM and overweight/obesity, compared to their non-nudge counterparts (control education, CE; control tableware, CT). Methods: A 2 × 2 factorial cluster RCT was conducted in 12 primary healthcare settings in China (pre-registered as ChiCtr2100044471). Participants were randomly assigned to the nudging education group (NE + CT), the nudging tableware group (CE + NT), the combined group (NE + NT) or the full-control group (CE + CT) for 1 month. The primary outcome was HbA1c. Secondary outcomes included dietary behaviours, metabolic indicators, and psychological health. Generalized linear mixed models were used for analysis. Results: A total of 284 participants (mean age, 52.28 years; 54.3% male) were randomly assigned and included in the analysis. After 6 months, NE and NT independently led to HbA1c reductions (−0.76%, p < 0.001; −0.33%, p = 0.042, vs. controls), with an additive but non-interactive effect when combined, resulting in a 1.04% reduction (p < 0.001) in the combined group. They also improved total calorie, macronutrient, and vegetable intake, FBG, plasma lipids, and BMI. NE additionally reduced diabetes distress and enhanced self-efficacy. Conclusions: Both NE and NT improved dietary and metabolic outcomes without increasing the psychological burden. The combined group showed the greatest benefits. Findings highlighted the importance of considering automatic processes in diabetes management. Full article

This study investigates the transformation of Acmella oleracea with the Agrobacterium rhizogenes rolC gene and evaluates its impact on phytochemical composition and biological activity. A total of 480 plant nodes were subjected to Agrobacterium−mediated transformation, leading to the regeneration of 35 putative transgenic plants. Molecular analysis confirmed the presence of the rolC transgene in 17 clones, of which four (C123, C127, C129, and C132) exhibited rolC mRNA expression. Phytochemical profiling of hydroalcoholic extracts of aerial parts (AP) and roots (R) revealed significant differences (p ≤ 0.05) between transgenic and non-transgenic plants (CTR). Compared to non−transgenic plants, transgenic AP exhibited lower total phenolic content but retained or increased flavonoid concentrations, particularly flavan−3−ols, whereas R extracts consistently showed reduced secondary metabolite levels. LC−DAD−ESI−MS analysis identified a diverse metabolite profile, with AP being notably rich in flavonoids (48.65%) and alkylamides (32.43%), including spilanthol. Functional assessments across antioxidant and anti−inflammatory assays demonstrated that R extracts exhibited stronger bioactivity compared to AP extracts, as indicated by lower IC₅₀ values (0.004–2.18 mg/mL for R vs. 0.007–7.24 mg/mL for AP). However, iron−chelating capacity was higher in AP extracts, correlating with flavonoid concentration. Hierarchical clustering confirmed that transgenic lines C123 and C127 most closely resembled the control, while C129 and C132 displayed distinct metabolic profiles. These findings highlight rolC’s role in modulating secondary metabolite synthesis, influencing both the phytochemical composition and functional properties of A. oleracea extracts. Full article

Objectives: This study will characterize continuous glucose monitoring (CGM) data in patients with type 2 diabetes in China, and assess the relationship between CGM-derived indicators and diabetes-related clinical parameters. Methods: The data for this study were collected from a randomized trial in China (ChiCTR2000039424) from February 2020 to July 2022 in which patients wore a CGM device for 14 days. Glycemia risk index (GRI), coefficient of variation (CV), standard deviation (SD), mean amplitude of glycemic excursions (MAGE), time in range (TIR), time above range (TAR), time below range (TBR), and estimate glycated hemoglobin (eA1c) were analyzed. Ordinary least square linear regression and the Spearman method were used to test the relationship between CGM-derived indicators and diabetes-related clinical parameters. Results: In all, 528 patients with type 2 diabetes from a randomized controlled trial were analyzed. It was shown that CV, SD, and MAGE increased with age and diabetes duration, but decreased with an increase in body mass index. Higher fasting plasma glucose, higher baseline HbA1c, and higher insulin resistance levels were associated with higher GRI, SD, MAGE, TAR, and eA1c, and they were associated with lower TIR. In addition, higher HOMA-2β was associated with higher TIR and TBR, and with lower TAR and eA1c. Hemoglobin had positive correlations to SD, TAR, and eA1c. Conclusions: It was found that glucose variability increased with age and the duration of diabetes. However, glucose variability decreased with increased BMI. Meanwhile, greater glycemic variability was associated with worse islet function, higher baseline glucose level, and higher hemoglobin. Full article

Lung cancer, particularly non-small-cell lung cancer (NSCLC), remains a leading cause of cancer-related mortality, with cisplatin-based chemotherapy being a standard treatment. However, the development of chemoresistance significantly limits its efficacy, necessitating alternative therapeutic approaches. Here, we demonstrate the anticancer effects of the extracts of Allium pseudojaponicum Makino (APE), a salt-tolerant plant, in cisplatin-resistant NSCLC. Metabolite profiling using UPLC-Q-TOF-MS^E identified 13 major compounds, predominantly alkaloids (71.65%) and flavonoids (8.81%), with key bioactive constituents such as lycorine (29.81%), tazettine (17.22%), and tricetin (8.19%). APE significantly inhibited cell viability in A549 and H460 cells, reducing viability to 38.6% (A549-Ctr), 37.2% (A549-CR), 28.4% (H460-Ctr), and 30.4% (H460-CR) at 40 µg/mL after 48 h. APE also suppressed colony formation by over 90% in both 2D and soft agar assays, while showing no cytotoxicity in normal human keratinocytes up to 80 µg/mL. Flow cytometry analysis revealed APE-induced G1 phase arrest, with the G1 population increasing from 50.4% to 56.6% (A549-Ctr) and 47.5% to 58.4% (A549-CR), accompanied by reduced S phase populations. This effect was associated with the downregulation of G1/S transition regulators, including cyclin D1, CDK4, cyclin E, and CDK2. Furthermore, proteomic analysis identified STAT3 signaling as a major target of APE; APE decreased phosphorylated STAT3 and c-Myc expression, and STAT3 knockdown phenocopied the effects of APE. These findings highlight the potential of APE as a natural product-based therapeutic strategy for overcoming cisplatin resistance in NSCLC. Full article

Agroforestry contributes to slowing deforestation, favoring ecosystem regeneration and improving land use sustainability. This study evaluated the impact of silvopastoral systems on soil recovery and their capacity to sequester and stabilize carbon (C) and nitrogen (N) in degraded soils of a native Nothofagus obliqua forest in Ranchillo Alto (37°04′52″ S, 71°39′14″ W), Ñuble Region, Chile. Three open (Op), semi-open (SOp), and semi-closed (SC) silvopastoral systems were analyzed and compared with a control (Ctr) without silvopastoral management across four soil depths (0–10, 10–20, 20–30, 30–60 cm). Physical, chemical, and biological analyses were performed, along with soil physical organic matter (SOM) fractionation. The highest C levels were found in the 0–10 cm depth (13.9, 11.8, 11.5, and 8.5% for Op > SC > SOp and Ctr, respectively). Despite its higher degradation, Op presented the highest levels of C, N, and non-oxidizable C (Cnox), possibly due to pyrogenic carbon from old potato burns. Furthermore, the same trend was observed for mineral associated organic matter (MAOM) fraction and C stocks in all silvopastoral systems compared to the control. These results underline the potential of silvopastoral practices to improve soil quality and increase long-term carbon sequestration, contributing to sustainable soil restoration strategies.

Based on first-principles calculations, the stability of three adsorption configurations of glycine on the (100) surface of diamonds was studied, leading to an investigation into the surface-enhanced Raman scattering (SERS) effect of the diamond substrate. The results showed that the carboxyl-terminated adsorption configuration (CAR) was the most stable and shortest interface distance compared to other configurations. This stability was primarily attributed to the formation of strong polar covalent bonds between the carboxyl O atoms and the surface C atoms of the (100) surface of diamonds. These results were further corroborated by first-principles molecular dynamics simulations. Within the temperature range of 300 to 500 K, the glycine molecules in the carboxyl-terminated adjacent-dimer phenyl-like (CAR) configuration exhibited only simple thermal vibrations with varying amplitudes. In contrast, the metastable ATO and carboxyl-terminated trans-dimer phenyl-like ring (CTR) configurations were observed to gradually transform into benzene-ring-like structures akin to the CAR configuration. After adsorption, the intensity of glycine’s characteristic peaks increased substantially, accompanied by a blue shift phenomenon. Notably, the characteristic peaks related to the carboxyl and amino groups exhibited the highest enhancement amplitude, exceeding 200 times, with an average enhancement amplitude exceeding 50 times. The diamond substrate, with its excellent adsorption properties and strong surface Raman spectroscopy characteristics, represents a highly promising candidate in the field of biomedicine. Full article
