Abstract

Neuroinflammation, an inflammatory response within the central nervous system (CNS), plays a critical role in various neurological disorders, including neurodegenerative diseases. Alpha linolenic acid (ALA), an essential omega-3 polyunsaturated fatty acid, has shown promising health benefits due to its antioxidant and anti-inflammatory properties. This article aims to thoroughly examine the potential effects of ALA in reducing neuroinflammation, emphasizing its roles as an anti-inflammatory and antioxidant agent. The review focuses on studies published between 2018 and 2023, sourced from reputable academic databases such as PubMed, Semantic Scholar, Google Scholar, and ScienceDirect, with nine key papers selected. The findings indicate that ALA significantly mitigates neuroinflammation by decreasing reactive oxygen species (ROS) via the Nrf-2/HO-1/JNK signaling pathway. Additionally, ALA reduces inflammatory cytokines by inhibiting p-JNK activation, disrupting lipid rafts, blocking the pro-inflammatory transcription factor NF-κB, and altering cell membrane phospholipid composition. The review concludes that ALA may have potential therapeutic effects in reducing neuroinflammation through its antioxidant and anti-inflammatory actions, offering possible benefits for various neurological conditions, including Alzheimer's and Parkinson's diseases.

Abstract

Background: Dyslipidemia can cause various organ disorders, such as fatty liver disease. Over time, fatty liver disease has become more commonplace worldwide and may cause mortality if the progression worsens. Natural components from Euphorbia milii (E. milii) and propolis (EMP) have been demonstrated as immunomodulators that reduce total cholesterol levels.Objective: To prove the effect of EMP tea on inhibiting fatty liver and hepatocyte apoptosis in high-fat diet (HFD)-induced rats.Methods: This study applied a post-test-only control group design using 18 Wistar rats, which were divided into three groups: K0 (received standard feed), KN (received HFD of 2 g/200 g Body weight (BW) in a day), and P (received HFD of 2 g/200 g BW in a day and EMP of tea 40 mg/100 g BW in a day). The interventions were conducted for 30 days, followed by termination on day 31 for liver tissue collection and analysis. We calculated the hepatic steatosis with the help of hematoxylin-eosin (HE) staining. Hepatocyte apoptosis was also determined with terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining.Results: The K0 group had a lower hepatic steatosis percentage (17.87 ± 1.81) than KN (63.75 ± 15.88). We also found no hepatocyte apoptosis in the K0 but a high hepatocyte apoptosis index in the KN (3.98 ± 0.29). The combination of EMP tea in HFD-induced rats significantly reduced hepatic steatosis and apoptosis percentage (25.33 ± 1.17 and 0.91 ± 0.61, respectively). Conclusion: We demonstrated that combining EMP tea reduced hepatic steatosis and hepatocyte apoptotic index in HFD-induced rats, suggesting its potential as a treatment for these conditions.

Abstract

Ultraviolet B (UVB) exposure is a major cause of skin aging, leading to collagen degradation and wrinkles due to free radical damage. Stevia (Stevia rebaudiana Bertoni) has antioxidant properties that may counteract this by preserving Transforming Growth Factor-β1 (TGF-β1), essential for collagen synthesis. This study evaluated the effects of stevia leaf extract cream on TGF-β1 and collagen levels in male Wistar rats. Thirty rats were divided into five groups: K0 (no UVB, no cream), K1 (base cream), P1 (2.5% stevia cream), P2 (5% stevia cream), and P3 (10% stevia cream). Groups K1, P1, P2, and P3 were exposed to a cumulative UVB exposure of 840 mJ/cm2 over four weeks. The TGF-β1 levels measured by ELISA did not differ significantly among groups (p>0.05). However, collagen levels, assessed using Picro Sirius Red staining, varied significantly (p<0.05). The K1 exhibited significantly lower collagen compared to K0 (p=0.003), whereas the P2 group effectively prevented collagen degradation compared to K1 (K1: 65.87% vs. P2: 77.92%; p = 0.005). While stevia leaf extract cream did not prevent TGF-β1 reduction, it demonstrated a clear protective effect against UVB-induced collagen loss. Among the tested concentrations, 5% stevia leaf extract cream was the most effective in preserving dermal Collagen, highlighting its potential as a topical agent for preventing photoaging and maintaining skin structural integrity.

Abstract

Introduction: Interleukin-6 (IL-6) in healthy gingiva contributes to regulating the immune response and tissue homeostasis. Exposure of lipopolysaccharide (LPS) from the Porphyromonas gingivalis bacteria (P. gingivalis) in periodontal tissues can influence the role of IL-6, shifting it from a tissue homeostatic agent to a pro-inflammatory cytokine. This study aimed to determine the levels of IL-6 in the gingiva of male Wistar rats induced by P. gingivalis bacteria. Material and Methods: This research uses a posttest-only control group design. Thirty-two male Wistar rats were divided into two groups, each consisting of sixteen rats. The control group consisted of 16 male Wistar rats that were not induced with bacteria. The experimental group consisted of sixteen male Wistar rats with the induction of P. gingivalis bacteria. Results and Discussions: The results showed that the IL-6 levels in the healthy male Wistar rat group were lower than the IL-6 levels in the male Wistar rat group induced with P. gingivalis bacteria. More exposure to LPS due to the induction of P. gingivalis bacteria causes increased permeability of the gingival mucosal barrier, which can shift the tissue balance towards a pro-inflammatory state, resulting in increased production of IL-6. Conclusion: IL-6 levels increased in the gingiva of male Wistar rats induced with P. gingivalis bacteria.

Abstract

Photoaging is a major contributor to premature skin aging and is primarily caused by chronic exposure to ultraviolet (UV) radiation. UV induced oxidative stress, inflammation, and extracellular matrix degradation result in wrinkles, pigmentation, and loss of skin elasticity. This systematic review aimed to evaluate the phytochemical mechanisms of Tagetes erecta and assess its potential clinical relevance in preventing photoaging. A systematic literature search was conducted in PubMed, Science Direct, and Europe PMC for studies published between 2016 and 2026, following PRISMA 2020 guidelines. Studies were included if they investigated Tagetes erecta or phytochemical compounds known to be present in Tagetes erecta (e.g., lutein, zeaxanthin, flavonoids, phenolic acids) in UV-induced photoaging models. The findings indicate that Tagetes erecta contains bioactive compounds that reduce reactive oxygen species (ROS), enhance endogenous antioxidant defenses, suppress matrix metalloproteinase (MMP) expression, and preserve collagen integrity. Clinical studies evaluating carotenoids and related phytochemicals also found in Tagetes erecta reported improvements in minimal erythema dose, skin elasticity, hydration, pigmentation, and wrinkle appearance. Notably, only one study directly investigated Tagetes erecta in the context of photoaging, however, the available evidence is still limited and insufficient to establish strong clinical conclusions. Therefore, current clinical evidence remains largely indirect. Overall, Tagetes erecta represents a promising phytochemical source with strong mechanistic support, although further well-designed clinical studies are required.
