Background/Objectives: This study aimed to assess the associations between the Lifestyle Inflammation Score (LIS) and gestational diabetes mellitus (GDM), and glucose metabolism alterations (GMA) postpartum. Methods: A secondary analysis was conducted on 378 pregnant women at the end of pregnancy. Anthropometric, clinical, biochemical, and dietary parameters were evaluated. Postpartum reclassification was based on fasting serum glucose (>100 mg/dL), HbA1c (>5.7%), and/or a 2-h oral glucose tolerance test (>140 mg/dL). The LIS was calculated using a proxy index including smoking status, physical activity, and pregestational BMI, applying the beta coefficient from the original LIS model. Tertiles were created, with T3 indicating the highest level of proinflammatory exposure. Statistical analyses included Kruskal–Wallis, one-way ANOVA, linear-by-linear association, and multivariate logistic regression, adjusted for family history, gestational weight gain, carbonylated proteins, and adiponectin to evaluate associations between LIS and GDM, and adjusted for pharmacological treatment, gestational weight gain, and breastfeeding for LIS and GMA. Results: Higher LIS values were more common among women with GDM (T1 = 45.9%, T2 = 62.2%, T3 = 74.8%, p < 0.001) and among those with GMA (T1 = 34.4%, T2 = 45.6%, T3 = 53.7%, p = 0.019). Compared with the lowest tertile, the highest tertile of LIS was associated with greater odds of GDM (OR 3.72; 95% CI: 1.19–11.64, p = 0.024) and GMA (OR 2.69; 95% CI: 1.25–5.76, p = 0.011). Conclusions: A more proinflammatory lifestyle, as reflected by a higher LIS, increases the risk of progression to GDM and later to GMA. Full article

Jaboticaba (Plinia cauliflora), a Brazilian native fruit rich in bioactive compounds, exhibits potent anti-inflammatory and antioxidant properties. This pilot study evaluated the effects of jaboticaba peel supplementation on inflammatory and oxidative stress markers and uremic toxins among patients with chronic kidney disease (CKD) undergoing hemodialysis (HD) and explored its molecular effects in LLC-PK1 renal cells. A randomized, controlled clinical trial was conducted with 27 patients (55.0 [19.5] years, BMI 24.3 [3.8] kg/m2) on regular HD. Participants were allocated to receive the jaboticaba peel formulation (3.3 g/day, equivalent to ~667 mg of phenolic compounds) for 3 weeks or to routine treatment (control). Plasma levels of interleukin (IL)-1β and IL-17E (ELISA), lipid peroxidation (TBARS), protein carbonylation, and plasma levels of uremic were analyzed. LLC-PK1 cells were treated with 100 µL of jaboticaba peel formulation at different concentrations, and a panel of inflammatory genes was evaluated. While plasma IL-1β and IL-17E concentrations were increased in the control group, the jaboticaba group exhibited no significant changes, suggesting anti-inflammatory protection. Transcriptomic analysis revealed downregulation of key components of the TLR–MYD88–NF-κB–IL-1 axis after cell treatment. Additionally, cells treated with jaboticaba formulation (1.5%) showed reduced ROS levels, indicating antioxidant capacity. In conclusion, supplementation with jaboticaba peel attenuated the increase in pro-inflammatory markers in HD patients. These results suggest that jaboticaba peel holds promise as an adjuvant nutritional intervention for chronic inflammation in CKD. Full article

Poultry have higher blood glucose concentrations, which are 1.5–2 times those of their mammalian counterparts with equivalent body mass, yet do not show any adverse effects. However, the underlying mediators that inhibit systemic inflammation under hyperglycemia are unclear. In this study, chickens and rats were chosen as representatives of poultry and mammals, and the physiological differences in blood glucose regulation between them were investigated under control conditions and streptozotocin (STZ)-induced hyperglycemia, respectively, to explore the internal causes of hyperglycemia without symptoms in poultry. Firstly, the fasting blood glucose (FBG) and glucagon concentrations increased significantly (p < 0.01) and the insulin concentrations decreased when chickens and rats were treated with STZ (p < 0.001). STZ injections in rats resulted in higher oral glucose tolerance test (OGTT) and intraperitoneal insulin tolerance test (IPITT) levels (p < 0.001), but there was no significant difference in chickens. In addition, the body weight development of STZ-inducted rats was retarded, while it was not the case for chickens receiving STZ. Secondly, high glucose metabolism products, including advanced glycation end products (AGEs) were detected in STZ-inducted rats and chickens. The AGEs concentration in the rats receiving STZ was significantly higher than that in control group rats (p < 0.001); however, there was no significant difference in chickens. Also, the concentrations of free amino acids inhibiting AGEs were further explored, and higher concentrations of taurine, leucine, and lysine were observed in chickens than those observed in rats (p < 0.05). Moreover, the concentrations were decreased significantly in STZ-treated chickens (p < 0.05). Finally, the inflammation in tissues vulnerable to high blood glucose was examined, and it was found that there were significantly increased mRNA and protein expression levels of inflammatory factors such as nuclear factor-κB (NF-κB) and interleukin-1β (IL-1β) in STZ-injected rats (p < 0.001), while there was no obvious effect in STZ-induced chickens. The results revealed the damage and inflammation resulting from STZ-induced hyperglycemia in chickens were significantly lower compared to rats. This may be attributed to the high concentrations of free amino acids in chickens, which inhibit AGE formation by functioning as carbonyl scavengers. This study elucidates the underlying causes of the absence of inflammation in chickens compared to rats under hyperglycemic conditions, offering new insights for controlling diabetic complications.

Objectives: We examined how opposing running slopes can modulate interval training effects on aerobic performance and reduction–oxidation (REDOX) determinants. Methods: Fourteen physically active volunteers, assigned to either the Uphill group (UG) or the Downhill group (DG), completed 16 workouts of ten 30-s runs, at either +10% or −10% grade, with a work-to-rest ratio of 1:2 at 90% of their Maximum Aerobic Speed (MAS) over 8 weeks. Maximal oxygen uptake (VO2max), MAS, Running Economy (RE), time to exhaustion at MAS (Tmax), respiratory exchange ratio (RER), and blood lactate at rest, 5th, and 10th runs were evaluated pre-, mid-, and post-training. Also, REDOX markers [Total Antioxidant Capacity (TAC), Protein Carbonyls (PCs) were assessed in blood samples taken at rest and 3 min post-exercise of the first and last workouts. Results: VO2max was unchanged in both groups; in the DG, MAS increased (from 14.2 ± 1.7 to 15.0 ± 1.5 km/h, d = 0.43), and post-training RER significantly increased (from 1.06 ± 0.07 to 1.12 ± 0.03). In the last training session, blood lactate levels increased in the UG (from 9.30 ± 2.69 mmοl/L to 13.34 ± 4.64 mmοl/L) but remained low and unchanged in DG (<2 mmοl/L). Post-training, resting TAC decreased in both groups, and the exercise-induced rise in PC levels was attenuated. Conclusions: Despite the brief intervention, VO2max levels were maintained in both groups, with divergent changes in metabolic, REDOX, and performance indicators; uphill HIIT may serve for enhancing lactate tolerance, while downhill intermittent running may improve running economy.

Environmental stressors such as pollution and ultraviolet (UV) radiation contribute significantly to skin aging and skin photo-aging, alongside intrinsic chronological factors. Recent insights into longevity science have emphasized mitochondrial health, proteostasis, and autophagic balance as critical processes for maintaining skin integrity. This study investigates the protective potential of a natural product, Rose-derived PolyDeoxyRiboNucleotide (PDRN), against mitochondrial dysfunction and dysregulated autophagy in primary human keratinocytes subjected to environmental stress (benzo-a-pyrene and UV-A). PDRN was evaluated at 0.1%, 0.05%, and 0.01% concentrations. Mitochondrial function was assessed through membrane polarization, ATP/ADP ratio, Complex V (CV-ATP5A) levels, and citrate synthase levels. LAMP2A levels were quantified to evaluate the autophagic pathway. Complementary analyses were performed on ex vivo human skin explants, evaluating oxidative protein damage (carbonylation), Collagen I/III integrity, MMP1 and IL1a levels, and mitophagy markers (PINK1, PARK2). The results confirm significant protection of mitochondrial function, attenuation of oxidative stress, and modulation of autophagy-related pathways by PDRN across all models tested. These findings underscore the capacity of this novel natural product, a plant-derived PDRN, to mitigate environmental skin aging (and photo-aging) through mitochondrial maintenance and proteostasis regulation, positioning Rose-PDRN as a key active ingredient for dermocosmetic formulations targeting skin longevity biomarkers.

Background/Objectives: We previously reported that the flavanol (+)-epicatechin (+Epi) enhances adult mice short-term working memory and neurogenesis. This study aimed to characterize the effects of +Epi on short- and long-term memory, to modulate mitochondria structure/function, oxidative stress (OS) and inflammation associated cytokines in the hippocampus and pre-frontal cortex of aged rats. Methods: Experiments were conducted using aged (23 month old) male Sprague Dawley rats. The control group (n = 6/group) were exposed to vehicle (water) only while the treated group, was provided +Epi at 1 mg/kg/day by oral gavage for 8 weeks. Open-field recognition tests were used to evaluate short- and long-term memory. The hippocampus and frontal cortex were sampled and citrate synthase activity, ATP levels, mitochondrial proteins, cytokines (IL-1β, IL-6, TNF-a and IL-11), protein carbonylation, lipid peroxidation (malonaldehyde; MDA), superoxide dismutase 2 (SOD2), glutathione peroxidase (GPx) and catalase activity were quantified. Results: There was a significant improvement in both short- and long-term memory in the +Epi treated group vs. controls. Mitochondrial bioenergetics also improved with treatment as determined by increased citrate synthase activity and ATP content. Relative levels of the mitochondrial proteins mitofilin and complex V increased with +Epi. +Epi suppressed protein carbonyls and MDA levels. OS buffering systems were significantly enhanced with +Epi as per increases in SOD2, GPx and catalase enzyme activities. +Epi also decreased pro-inflammatory and stimulated anti-inflammatory cytokines vs. controls. Conclusions: Results demonstrate +Epi improves mitochondrial function, reduces OS and inflammation in the hippocampus and cortex leading to improved short- and long-term memory in aged animals providing evidence for possible mechanisms of action.

Cerebral amyloid angiopathy (CAA), present in more than 90% of Alzheimer’s disease (AD) cases, associates with focal ischemia and neurovascular dysfunction. Genetic variants at positions 21–23 of amyloid beta (Aβ), among them the Dutch mutation (AβE22Q), are primarily linked to CAA and the development of cerebral hemorrhages. An important contributor to CAA pathogenesis is the dysregulation of mitochondria-mediated pathways with concomitant induction of oxidative stress. Using biochemical assays and immunofluorescence microscopy, this work demonstrates the exacerbated formation of reactive oxygen species (ROS) in human brain microvascular endothelial cells after short exposure to soluble oligomers of synthetic homologues of Aβ1-42 and the Dutch variant, inducing lipid peroxidation and protein carbonylation, both markers of oxidative stress. The heterogeneity of the soluble oligomeric assemblies inducing this oxidative response was highlighted by their reactivity with two conformational antibodies recognizing specific and mutually exclusive epitopes associated with either soluble prefibrillar oligomers or soluble fibrillar oligomers. Treatment with the multitarget antioxidants Trolox and methazolamide significantly attenuated the Aβ-mediated ROS production and reduced oxidative stress markers to basal levels. Our data highlight the damaging role of heterogeneous Aβ oligomers and the preventing effect of antioxidants, suggesting ROS modulation as a complementary therapeutic strategy to preserve neurovascular unit integrity.

5-hydroxymethylfurfural (5-HMF) has been shown to exert neuroprotective effects in a global cerebral ischemia mouse model in our previous study, where it demonstrated antioxidant and anti-inflammatory properties. However, studies on its antidepressant mechanisms remain scarce. Since oxidative stress and neuroinflammation are closely associated with depression, this study investigated the antidepressant effects of 5-HMF, focusing on its potential inhibition of oxidative stress via the Nrf2 pathway and its role in microglial M1 polarization-mediated neuroinflammation. An acute depression mouse model induced by intraperitoneal injection of lipopolysaccharide (LPS) was utilized. Mice received 5-HMF (12 mg/kg) or an equal volume of vehicle via intraperitoneal injection 30 min prior to and 5 min after LPS administration. At 24 h post-modeling, behavioral tests (sucrose preference, forced swim, and open field tests) were conducted to evaluate the antidepressant effect of 5-HMF. Histological damage in the hypothalamus was assessed using Nissl staining and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) staining. Immunofluorescence was performed to evaluate M1 polarization of hypothalamic microglia. Oxidative stress damage was assessed by measuring malondialdehyde (MDA), carbonyl groups, and 8-hydroxy-2′-deoxyguanosine (8-OHdG) levels. Nrf2 DNA-binding activity was examined using an ELISA-based assay. The expression of inflammatory cytokines, Nrf2, and downstream antioxidant proteins was analyzed by ELISA kits and Western blotting. 5-HMF significantly alleviated LPS-induced depression-like behaviors, reduced hypothalamic neuronal damage, decreased oxidative stress, and inhibited microglial M1 polarization. It also regulated the expression of inflammatory cytokines (IL-1β, IL-6, TNF-α, IL-4, and IL-10) and activated the Nrf2 signaling pathway, enhancing nuclear translocation efficiency. Notably, these effects were significantly attenuated by the Nrf2 inhibitor brusatol. In conclusion, 5-HMF exerts neuroprotective effects by modulating Nrf2-mediated oxidative stress responses and suppressing microglial M1 polarization-driven neuroinflammation. These findings suggest that 5-HMF may provide therapeutic potential for alleviating depression symptoms induced by acute inflammation. Full article

Chemical modification is a valuable strategy for tuning enzyme functionality by introducing new reactive groups without disrupting the overall fold. Conventional amination using ethylenediamine (EDA) is effective, but the resulting modified proteins show limited reactivity for conjugation at neutral pH, and the modifier itself poses safety concerns due to its volatility and corrosive nature. Dihydrazides, in contrast, offer a safer and more versatile alternative: they operate through the same carboxyl-activation mechanism while enabling systematic investigation of chain-length effects. In this study, Thermomyces lanuginosus lipase (TLL) and Myceliophthora thermophila laccase (MTL) were modified using dihydrazides with different alkyl chain lengths (carbonyl (CZ), oxalyl (OX), succinyl (SC), and adipic (AA)), and compared to EDA-modified and unmodified enzymes to evaluate their effects on catalytic performance. Hydrazide-modified variants exhibited enhanced catalytic performance, reaching up to 2.5-fold (TLL-CZ) and 4.2-fold (MTL-AA and MTL-OX) higher efficiencies than unmodified and EDA-modified enzymes. Notably, AA provided the most consistent improvement across both enzymes (1.3-fold in TLL and the best in MTL). Molecular dynamics and docking analyses supported these findings, linking increased flexibility (higher RoG and RMSF) with higher kcat, and changes in substrate binding with lower km. Overall, hydrazide-based modification broadens the spectrum of enzyme variants attainable through amination, while offering safer procedures, thus representing an alternative that overcomes the limitations of using EDA as a conventional aminating agent.

Background: Fusarium solani (Fs), a drug-resistant phytopathogenic fungus, is a major cause of severe infections in both plants and humans. Artemisia annua and its derivatives exhibit antimicrobial, antiviral and anticholesterolemic activities, yet their clinical use has been dominated by potent antimalarial and anticancer effects. Artemisinin (ART), a sesquiterpene lactone isolated from A. annua, is well recognized for its antimalarial efficacy but remains underexplored as an antifungal agent. Methods: Conidia of Fs were treated with increasing concentrations of ART (75–500 μM) for 0 and 24 h. Fungal viability was assessed using viability assays. Membrane permeability was examined using confocal laser scanning microscopy with propidium iodide (PI) staining. Protein carbonylation assays were performed to quantify oxidative damage induced by ART. Results: A 24 h, ART exposure reduced Fs viability in a dose-dependent manner, with an IC50 of 147.5 μM. At 500 μM, ART achieved fungicidal activity with 99% growth inhibition. Confocal microscopy confirmed extensive membrane disruption in ART-treated conidia, while carbonylation assays demonstrated marked protein oxidation, supporting a mechanism involving free radical generation from the peroxide bridge of ART. ART exhibits potent antifungal activity against Fs, mediated by oxidative stress, membrane disruption and protein carbonylation. Conclusions: These findings highlight ART as a promising candidate for antifungal drug development against resistant Fusarium species. Full article

This study investigated the effects of direct vat set commercial yoghurt starter (B) and yeast starter (Y) on the quality of fermented large yellow croaker surimi balls, with natural fermentation (CTR) as a control. Surimi products were inoculated and fermented at 25 °C for 4 h, then analyzed for physicochemical, sensory, and oxidative properties. Yoghurt starter significantly inhibited protein oxidation, as indicated by the highest sulfhydryl content (9.10 nmol/mg protein, p < 0.05), improved textural properties (hardness was 28% higher than CTR, p < 0.05), and promoted a balanced flavor profile, accompanied by the highest equivalent umami concentration (1.66%, p < 0.05). However, B also caused the greatest MDA accumulation (1.49 mg/kg, p < 0.05), reflecting enhanced lipid oxidation. By comparison, Y enhanced umami primarily through significant enrichment of aspartic acid (53.88 mg/100 g, p < 0.05) and accelerated nucleotide degradation, resulting in the highest AMP and hypoxanthine levels (p < 0.05). These advantages were offset by severe protein carbonylation (54.32 nmol/mg protein, p < 0.05) and evident color deterioration. Sensory analysis revealed no significant difference between B and CTR (p > 0.05), whereas Y received significantly lower acceptance scores (p < 0.05) due to impaired color and taste. These findings suggest that B is a promising starter for improving texture and flavor in fermented surimi balls, while Y, despite enhancing umami and controlling lipid oxidation, negatively affects color, texture, and protein stability.

Polianthes tuberosa L. (PT) flower extracts exhibit considerable bioactivities, yet their application is often constrained by limited bioavailability and efficacy. In this study, fermentation of PT (FPT) using Rhodosporidium toruloides significantly enhanced its phytochemical profile, doubling the total phenol content (697.22 ± 7.51 μg/mL in FPT versus (vs.) 347.61 ± 5.89 μg/mL in non-fermented extract (NF)) and increasing flavonoids by onefold relative to NF (381.44 ± 6.50 μg/mL in FPT vs. 190.25 ± 4.75 μg/mL in NF), resulting in a substantial improvement in radical scavenging capacity (DPPH: 47.59 ± 1.55%; ABTS: 89.87 ± 1.39%). In UVB-irradiated the human keratinocyte cell line, FPT demonstrated superior efficacy over NF by effectively reducing reactive oxygen species and malondialdehyde levels (1.29 ± 0.08 ng/mL at 0.4 mg/mL FPT vs. 1.5 ± 0.1 ng/mL with NF), while concurrently elevating the activity of key antioxidant enzymes. Using human dermal fibroblasts, FPT was further shown to possess notable anti-glycation and anti-carbonylation properties, significantly inhibiting carboxymethyl lysine formation (90.6 ± 3.6% reduction) and protein carbonylation (86.5 ± 2.2% reduction). It also suppressed senescence-associated β-galactosidase activity (67.9 ± 3.0% inhibition), downregulated matrix metalloproteinase-1 expression (62.5 ± 5.1% reduction), and stimulated type I collagen synthesis (166.5 ± 4.2% recovery). Additionally, FPT markedly inhibited UVB-induced melanogenesis in B16F10 melanoma cells by reducing melanin content (36.0 ± 5.3%) and tyrosinase activity (45.7 ± 1.2%), through the downregulation of critical melanogenic genes, including melanocortin 1 receptor, microphthalmia-associated transcription factor, and tyrosinase.

Background: Sepsis is a leading cause of mortality in intensive care units, with liver dysfunction representing a critical determinant of poor outcome, mainly associated with excessive inflammation and oxidative stress. Lycopene, a carotenoid with potent antioxidant and anti-inflammatory properties, has been proposed as a potential therapeutic agent. This study investigated whether lycopene supplementation mitigates lipopolysaccharide-induced oxidative and inflammatory liver injury in rats. Methods: Male Wistar rats, divided into four groups, were exposed to either lipopolysaccharide or a combination of lipopolysaccharide (10 mg/kg) and lycopene (6 mg/kg). In order to assess liver damage induced by lipopolysaccharide, hepatocellular injury markers, oxidative stress indices, nitric oxide metabolism, glutathione redox status, apoptotic enzyme activity, and inflammatory mediators were assessed in serum and liver tissue. Results: Lipopolysaccharide induced marked hepatocellular damage, characterized by elevated serum liver-cell damage parameters, and liver tissue xanthine oxidase, myeloperoxidase, thiobrabituric reactive substances, protein carbonyl content, deoxyribonuclease I/II activity, nuclear factor kappa B, tumor necrosis factor-α, and interleukin-6, alongside depletion of reduced glutathione and reduced glutathione reductase and glutathione peroxidase activities. Lyc pretreatment significantly attenuated liver enzyme leakage, oxidative damage, and cytokine release while restoring reduced glutathione and glutathione reductase activity. In contrast, lycopene had limited effects on glutathione peroxidase activity, nitric oxide/inducible nitric oxide synthase signaling, and nuclear factor erythroid 2-related factor 2 expression. Conclusions: These findings demonstrate that lycopene confers partial hepatoprotection in endotoxemic rats, primarily through suppression of oxidative damage and nuclear factor kappa B-mediated inflammation. Further studies are needed to clarify tissue-specific mechanisms and optimize dosing strategies in order to increase the efficacy of this carotenoid. Full article

Due to the high toxicity and widespread distribution of aflatoxin B1 (AFB1), there is significant interest in efficient, safe, and environmentally friendly microbial degradation methods. Rhodococcus opacus PD630 cell-free supernatant (RCFS) shows excellent activity in degrading AFB1, but its active components and mechanisms remain unclear. We assessed the feasibility of ethanol precipitation to enrich active components in RCFS and characterized the ethanol precipitate (RCFSC-EP). Metabolomics and proteomics were used to elucidate the active components, mechanisms, and products of AFB1 degradation by RCFS. The results indicate that ethanol precipitation enriches over 80% of the active components for AFB1 degradation in RCFS. RCFSC-EP exhibits excellent heat resistance, and inhibitors like EDTA-2Na and proteinase K significantly inhibit its activity. Multi-omics analysis suggests that active components in RCFS metabolize AFB1 into six products through four potential pathways, three of which withstand 135 °C for 20 min. The AFB1-degrading activity of RCFS is an intrinsic, constitutive trait of R. opacus PD630 during normal growth. The active components are diverse proteins or enzymes, including glutathione S-transferases, aldo/keto reductase, peroxidases, and carbonyl reductases. This study enriches and reveals the active components, pathways, and products of AFB1 degradation by RCFS, providing a basis for developing RCFS as a biological agent for AFB1 degradation.

This study evaluated the effects of enzymatically produced collagen hydrolysate and Salicornia perennans extract on the quality, oxidative stability, and nutritional composition of canned canine meat pâtés. Two formulations were prepared: a control 2% NaCl, no hydrolysate and an experimental sample containing 3% collagen hydrolysate sheep:camel:bovine = 1:1:1, 1% Salicornia perennans extract, and 1% NaCl. Physicochemical, textural, amino-acid, fatty-acid, and oxidative parameters were monitored over 10 days of storage. The treated pâtés showed similar proximate composition moisture 76.1%, protein 9.2%, metabolizable energy (ME) 102 kcal·100 g−1; p > 0.05 but exhibited enhanced functional stability, with reduced water loss syneresis 1.8 vs. 3.1%; p < 0.05 and improved cohesiveness 0.46 vs. 0.41; p < 0.05. Amino-acid enrichment included higher aspartic acid +33%; p < 0.05, methionine +53%; p < 0.05, and tryptophan +39%; p < 0.05, while the lipid profile showed lower SFA 52.8 vs. 56.4%; p < 0.05, higher n-3 PUFA 1.5 vs. 0.8%; p < 0.05, and a reduced n-6:n-3 ratio 3.8 vs. 5.6; p < 0.05. During storage, oxidative markers decreased: TBARS −45%, carbonyls −14%, acid value −18%, and color stability improved by +2.0 pp. These findings confirm the synergistic antioxidant and structuring effects of collagen-derived peptides and Salicornia polyphenols, as evidenced by a 45% reduction in TBARS, 14% lower protein carbonyls, and 18% lower acid value relative to the control (p < 0.05). This synergy enabled a sodium-reduced, clean-label formulation with improved technological performance, oxidative resistance, and shelf-life stability for functional wet dog foods. In addition, it enhanced the color and visual appeal—key attributes that influence both animal palatability and the purchasing decisions of pet owners. Full article
