Bioactivity of Amphidinol-Containing Extracts of Amphidinium carterae Grown Under Varying Cultivation Conditions.

Microalgae are of great interest due to their ability to produce valuable compounds, such as pigments, omega-3 fatty acids, antioxidants, and antimicrobials. The dinoflagellate genus Amphidinium is particularly notable for its amphidinol-like compounds, which exhibit antibacterial and antifungal properties. This study utilized a two-stage cultivation method to grow Amphidinium carterae CCAP 1102/8 under varying conditions, such as blue LED light, increased salinity, and the addition of sodium carbonate or hydrogen peroxide. After cultivation, the biomass was extracted and fractionated using solid-phase extraction, yielding six fractions per treatment. These fractions were analyzed using Liquid Chromatography-High-Resolution Mass Spectrometry (LC-HRMS/MS) to identify their chemical components. Key amphidinol compounds (AM-B, AM-C, AM-22, and AM-A) were identified, with AM-B being the most abundant in Fraction 4, followed by AM-C. Fraction 5 also contained a significant amount of AM-C along with an unknown compound. Fraction 4 returned the highest antimicrobial activity against the pathogens Staphylococcus aureus, Enterococcus faecalis, and Candida albicans, with Minimal Biocidal Concentrations (MBCs) ranging from 1 to 512µg/mL. Results indicate that the modulation of both amphidinol profile and fraction bioactivity can be induced by adjusting the cultivation parameters used to grow two-stage batch cultures of A. carterae.

Dietary Fat Intake on Metabolic Health: An in-Depth Analysis of Epidemiological, Clinical, and Animal Studies

<i>Background: </i>The consumption of dietary fat plays a vital role in the maintenance of metabolic health as it exerts impact over several physiological processes, including lipid profiles, inflammation, and insulin sensitivity, among other factors. The aim of this comprehensive review seeks to assess the influence of dietary fat consumption on metabolic processes. <i>Methods:</i> An exhaustive and methodical exploration of pertinent databases, such as Web of Science, PubMed, and Scopus, was undertaken to identify animal studies, clinical trials, and epidemiological research. The search terms included "dietary fat," "metabolic health," "epidemiological studies," "clinical trials," and "animal studies". <i>Result:</i> Animal studies demonstrate that high intake of saturated fat impairs insulin sensitivity and glucose tolerance, while unsaturated fats such as monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) have beneficial effects. Observational studies in humans reveal that higher intake of saturated fat is associated with an increased risk of metabolic syndrome and type 2 diabetes, whereas unsaturated fats lower the risk. <i>Conclusion:</i> Clinical trials have further supported the importance of replacing SFAs with healthier fats, such as MUFAs and PUFAs, particularly omega-3 and omega-6 fatty acids, in improving metabolic health markers in human subjects. Instead of advising against fats altogether, it is important to specify the preferred types of fats to be consumed as part of a healthy diet and lifestyle.

Impact of Omega-3 Fatty Acid Supplementation in Parenteral Nutrition on Inflammatory Markers and Clinical Outcomes in Critically Ill COVID-19 Patients: A Randomized Controlled Trial.

The heightened inflammatory response observed in COVID-19 patients suggests that omega-3 fatty acids (O3FA) may confer anti-inflammatory benefits. This randomized, double-blind, single-center clinical trial aimed to evaluate the effect of O3FA supplementation in parenteral nutrition (PN) on inflammatory markers in COVID-19 patients admitted to the intensive care unit (ICU). A total of 69 patients were randomized into three groups: one received standard lipid emulsion, and two received O3FA (Omegaven®) at doses of 0.1 g/kg/day and 0.2 g/kg/day, respectively, in addition to Smoflipid®. The primary outcomes measured were serum levels of C-reactive protein (CRP) and interleukin-6 (IL-6) on days 1, 5, and 10 of PN initiation. Secondary outcomes included additional inflammatory markers (TNF-α, IFN-γ, IL-1Ra, CXCL10), hepatic function, triglyceride levels, and clinical outcomes such as mortality and length of ICU and hospital stay. Results indicated a significant reduction in CRP, IL-6, and CXCL10 levels in the group receiving 0.1 g/kg/day O3FA compared to the control. Additionally, the higher O3FA dose was associated with a shorter ICU and hospital stay. These findings suggest that O3FA supplementation in PN may reduce inflammation and improve clinical outcomes in critically ill COVID-19 patients.

The role of nutrition in mild traumatic brain injury rehabilitation for service members and veterans.

Veterans Affairs and the Department of Defense (DOD) acknowledge that nutrition may be a modifier of mild traumatic brain injury (TBI) sequelae. Military clinicians are considering nutritional supplements and dietary interventions when managing patients with mild TBI. Therefore, clinicians should be familiar with the current evidence for nutritional interventions in mild TBI and special considerations related to the military lifestyle. This narrative review aims to summarize the existing evidence surrounding the role of special diets and select nutrients in mild TBI outcomes, gut microbiota changes, and special considerations for Service members and Veterans recovering from mild TBI. We conducted a literature review in PubMed and Google Scholar limited to nutritional interventions and nine topics with primary focus on mild TBI, although we included some articles related to moderate-to-severe TBI where relevant: 1) ketogenic diet, 2) Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet, 3) omega-3 fatty acids, 4) creatine, 5) vitamin D, 6) weight management, 7) gut microbiota, 8) caffeine, and 9) alcohol. We summarized key findings and safety factors where appropriate for each intervention. We also identified nutritional supplement safety and operational rations considerations and areas in need of further research. Preclinical studies and early human trials suggest that the specific nutrients and diets discussed in the current article may offer neuroprotection or benefit during mild TBI rehabilitation. Omega-3 fatty acids, creatine, and vitamin D are generally safe when taken within recommended guidelines. More evidence is needed to support nutritional recommendations for enhancing neuroprotection and mitigating mild TBI symptoms in humans. The DOD's Warfighter Nutrition Guide recommends a whole food diet rich in antioxidants, phytonutrients, omega-3 fatty acids, micronutrients, probiotics, and fiber to optimize long-term health and performance.

Multisample lipidomic profiles of irritable bowel syndrome and irritable bowel syndrome-like symptoms in patients with inflammatory bowel disease: new insight into the recognition of the same symptoms in different diseases.

Overlapping clinical manifestations of irritable bowel syndrome (IBS) and IBS-like symptoms in patients with inflammatory bowel disease (IBD-IBS) present challenges in diagnosis and management. Both conditions are associated with alterations in metabolites, but few studies have described the lipid profiles. Our aim was to pinpoint specific lipids that contribute to the pathogenesis of IBS and IBD-IBS by analyzing multiple biologic samples. Diarrhea-predominant IBS (IBS-D) patients (n = 39), ulcerative colitis in remission with IBS-like symptoms patients (UCR-IBS) (n = 21), and healthy volunteers (n = 35) were recruited. IBS-D patients meet the Rome IV diagnostic criteria, and UCR-IBS patients matched mayo scores ≤ two points and Rome IV diagnostic criteria. Serum, feces, and mucosa were collected for further analysis. Lipid extraction was carried out by ultra-performance liquid chromatography-high resolution mass spectrometry (UPLC-HRMS). Lipidomics of mucosa and serum samples significantly differed among the three groups. Feces showed the most altered lipid species, and the enrichment analysis of 347 differentially abundant metabolites via KEGG pathway analysis revealed that alpha-linolenic acid metabolism was significantly altered in the two groups (P < 0.01). The ratio of omega-6/omega-3 fatty acid were imbalance in serum samples. This study revealed a comprehensive lipid composition pattern between IBS-D patients and UCR-IBS patients. We found several distinctive lipids involved in alpha-linolenic acid metabolism, reflecting an imbalance in the omega-6/omega-3 fatty acid ratio. Compared to mucosa and serum samples, fecal samples might have more advantages in lipidomics studies due to the convenience of sample collection and effectiveness in reflecting metabolic information.

Decomposed interaction testing improves detection of genetic modifiers of the relationship of dietary omega-3 fatty acid intake and its plasma biomarkers with hsCRP in the UK Biobank.

Discovery and translation of gene-environment interactions (GxEs) influencing clinical outcomes is limited by low statistical power and poor mechanistic understanding. Molecular omics data may help address these limitations, but their incorporation into GxE testing requires principled analytic approaches. We focused on genetic modification of the established mechanistic link between dietary long-chain omega-3 fatty acid (dN3FA) intake, plasma N3FA (pN3FA), and chronic inflammation as measured by high sensitivity CRP (hsCRP). We considered an approach that decomposes the overall genetic effect modification into components upstream and downstream of a molecular mediator to increase the potential to discover gene-N3FA interactions. Simulations demonstrated improved power of the upstream and downstream tests compared to the standard approach when the molecular mediator for many biologically plausible scenarios. The approach was applied in the UK Biobank (N = 188,700) with regression models that used measures of dN3FA (based on fish and fish oil intake), pN3FA (% of total fatty acids measured by nuclear magnetic resonance), and hsCRP. Mediation analysis showed that pN3FA fully mediated the dN3FA-hsCRP main effect relationship. Next, we separately tested modification of the dN3FA-hsCRP ("standard"), dN3FA-pN3FA ("upstream"), and pN3FA-hsCRP ("downstream") associations. The known FADS1-3 locus variant rs174535 reached p = 1.6×10-12 in the upstream discovery analysis, with no signal in the downstream analysis (p = 0.94). It would not have been prioritized based on a naïve analysis with dN3FA exposure and hsCRP outcome (p = 0.097), indicating the value of the decomposition approach. Gene-level enrichment testing of the genome-wide results further prioritized two genes from the downstream analysis, CBLL1 and MICA, with links to immune cell counts and function. In summary, a molecular mediator-focused interaction testing approach enhanced statistical power to identify GxEs while homing in on relevant sub-components of the dN3FA-hsCRP pathway.

Salt-sensitive hypertension in GR mutant rats is associated with altered plasma polyunsaturated fatty acid levels and aortic vascular reactivity.

In humans, glucocorticoid resistance is attributed to mutations in the glucocorticoid receptor (GR). Most of these mutations result in decreased ligand binding, transactivation, and/or translocation, albeit with normal protein abundances. However, there is no clear genotype‒phenotype relationship between the severity or age at disease presentation and the degree of functional loss of the receptor. Previously, we documented that a GR+/- rat line developed clinical features of glucocorticoid resistance, namely, hypercortisolemia, adrenal hyperplasia, and salt-sensitive hypertension. In this study, we analyzed the GR+/em4 rat model heterozygously mutant for the deletion of exon 3, which encompasses the second zinc finger, including the domains of DNA binding, dimerization, and nuclear localization signals. On a standard diet, mutant rats exhibited a trend toward increased corticosterone levels and a normal systolic blood pressure and heart rate but presented with adrenal hyperplasia. They exhibited increased adrenal soluble epoxide hydroxylase (sEH), favoring an increase in less active polyunsaturated fatty acids. Indeed, a significant increase in nonactive omega-3 and omega-6 polyunsaturated fatty acids, such as 5(6)-DiHETrE or 9(10)-DiHOME, was observed with advanced age (10 versus 5weeks old) and following a switch to a high-salt diet accompanied by salt-sensitive hypertension. In thoracic aortas, a reduced soluble epoxide hydrolase (sEH) protein abundance resulted in altered vascular reactivity upon a standard diet, which was blunted upon a high-salt diet. In conclusion, mutations in the GR affecting the ligand-binding domain as well as the dimerization domain resulted in deregulated GR signaling, favoring salt-sensitive hypertension in the absence of obvious mineralocorticoid excess.

Fish Consumption and DHA Supplementation during Pregnancy: Study of Gestational and Neonatal Outcomes.

Several studies have explored the association between fish consumption during pregnancy and favorable neonatal outcomes, although some yield conflicting results. The American College of Obstetricians and Gynecologists recommends two to three servings of low-mercury fish per week for pregnant or breastfeeding women. However, fish can be a source of pollutants, like methylmercury, impacting neurological development. Conflicting studies on docosahexaenoic acid (DHA) supplementation exist in the literature, possibly due to varied supplement dosages. This survey, involving 501 women, investigated fish consumption and DHA supplement intake concerning gestational and neonatal outcomes. Notably, 92.1% of participants consumed fish weekly, with significant differences observed in gestational weight gain, birth weight, and length for those eating fish ≥3 times weekly compared to non-consumers. This study supports the recommendation for pregnant women to include fish in their diet while limiting exposure to environmental pollutants. Omega-3 fatty acid supplements are suggested to attain nutritional benefits without mercury risk.

The impact of omega-3 fatty acids in a combined experimental model of periodontitis and metabolic syndrome

Relevance. Periodontitis and metabolic syndrome are interrelated conditions that often aggravate each other through shared pathogenic mechanisms, highlighting the need for integrated immunomodulatory therapeutic approaches. Despite this, existing literature presents inconsistent data regarding the interplay between periodontitis and metabolic syndrome, as well as limited insights into the potential benefits of omega-3 polyunsaturated fatty acids (ω-3 PUFAs) as an adjuvant therapy. Specifically, the role of ω-3 PUFAs in modulating the inflammatory response and mitigating bone resorption remains inadequately explored. Therefore, this study aims to evaluate the inflammatory response and osteoresorption in periodontal tissues under the combined conditions of periodontitis and metabolic syndrome, while also assessing the therapeutic effects of ω-3 PUFAs.Materials and methods. This experimental study was conducted using 30 male Wistar rats, which were randomly assigned to one of five groups: a control group, a periodontitis group, a combined periodontitis and metabolic syndrome group, a periodontitis group treated with omega-3 fatty acids, and a combined periodontitis and metabolic syndrome group treated with omega-3 fatty acids. The study employed several research methodologies. Biochemical analyses were performed to confirm the presence of metabolic syndrome. Histopathological and morphometric assessments were conducted to evaluate the inflammatory response, the extent of osteoresorption, and the number of osteoclasts in the periodontal tissues. Additionally, molecular genetic analysis was used to measure the relative mRNA expression levels of key inflammatory and osteoclastogenic markers, including TNFα, IL-1β, RANK, and OPG.Results. The data demonstrated that metabolic syndrome in laboratory animals significantly exacerbates both the pro-inflammatory response and the extent of lacunar osteoclastic bone resorption. Administration of ω-3 PUFAs at a dose of 40 mg/kg over 30 days led to a statistically significant reduction in inflammatory infiltration within the periodontal tissues (3.17 ± 0.21 in the control group vs. 1.83 ± 0.21 in the treated group, р = 0.001) and a decrease in the number of osteoclasts (3,75 ± 0,45 in the control group vs. 1,75 ± 0,35 in the treated group, р = 0.003). Additionally, there was a notable reduction in the expression levels of TNFα, IL-1β, and RANK mRNA. Similar but less pronounced effects were observed in the group with combined metabolic syndrome following ω-3 PUFA administration.Conclusion. These findings enhance the current understanding of the interplay between periodontitis and metabolic syndrome, highlighting the potential of ω-3 PUFAs as a preventive or therapeutic intervention. ω-3 PUFAs may be effective in mitigating inflammatory responses and bone resorption, both in cases of isolated periodontitis and when accompanied by metabolic syndrome.

Novel Therapeutic Approaches in Alzheimer's Disease

Alzheimer's disease (AD) is a neurological condition associated with a decrease in levels of acetylcholine and diminished cholinergic functions. This may be caused by the degeneration of cholinergic neurons in the brain, leading to cognitive deficits. Due to the difficulty and invasiveness of collecting cerebrospinal fluid (CSF) required for assessing conventional biomarkers, researchers are currently exploring less intrusive, less expensive, and more straightforward methods for diagnosing AD. Additionally, conventional interventions such as cholinesterase inhibitors like rivastigmine, donepezil, and galantamine are US FDA-approved drugs that are still effective for managing AD. The goal of this therapy is to increase acetylcholine levels in the brain by inhibiting the enzymes that degrade acetylcholine. Therefore, this therapeutic approach is useful for treating mild-to-moderate AD. However, only symptomatic treatment is currently available, and it can lead to serious adverse effects from conventional therapy. Thus, novel therapies for AD are needed in a growing global population. This manuscript provides information on various biomarkers with possible pathogenesis mechanisms, novel treatment strategies such as microalgae, HupA, cannabinoids, and the beneficial effects of coenzyme Q10, bacterial probiotics, omega-3 fatty acids, vitamin B12, and D3 in memory impairment for managing AD. Non-pharmacological treatments such as music therapy, Electroacupuncture (EA), or manual acupuncture (MA) also play an important role in enhancing the effectiveness of conventional pharmacological treatments for AD.

NR2F2 Reactivation in Early-life Adipocyte Stem-like Cells Rescues Adipocyte Mitochondrial Oxidation.

In humans, perinatal exposure to an elevated omega-6 (n6) relative to omega-3 (n3) Fatty Acid (FA) ratio is associated with the likelihood of childhood obesity. In mice, we show perinatal exposure to excessive n6-FA programs neonatal Adipocyte Stem-like cells (ASCs) to differentiate into adipocytes with lower mitochondrial nutrient oxidation and a propensity for nutrient storage. Omega-6 FA exposure reduced fatty acid oxidation (FAO) capacity, coinciding with impaired induction of beige adipocyte regulatory factors PPARγ, PGC1α, PRDM16, and UCP1. ASCs from n6-FA exposed pups formed adipocytes with increased lipogenic genes in vitro, consistent with an in vivo accelerated adipocyte hypertrophy, greater triacylglyceride accumulation, and increased % body fat. Conversely, n6-FA exposed pups had impaired whole animal 13C-palmitate oxidation. The metabolic nuclear receptor, NR2F2, was suppressed in ASCs by excess n6-FA intake preceding adipogenesis. ASC deletion of NR2F2, prior to adipogenesis, mimicked the reduced FAO capacity observed in ASCs from n6-FA exposed pups, suggesting that NR2F2 is required in ASCs for robust beige regulator expression and downstream nutrient oxidation in adipocytes. Transiently re-activating NR2F2 with ligand prior to differentiation in ASCs from n6-FA exposed pups, restored their FAO capacity as adipocytes by increasing the PPARγ-PGC1α axis, mitochondrial FA transporter CPT1A, ATP5 family synthases, and NDUF family Complex I proteins. Our findings suggest that excessive n6-FA exposure early in life dampens an NR2F2-mediated induction of beige adipocyte regulators, resulting in metabolic programming that is shifted towards nutrient storage.

Health benefit of flaxseed (Linum usitatissimum): a mini review

The importance of nutrition and its impact on human well-being has increased interest in "functional foods." This has prompted a reevaluation of the practical advantages offered by various conventional food sources. it is the richest known source of alpha-linolenic acid (ALA), phytoestrogen lignans, and solubility fiber, flax continues to acquire popularity as a functional food and is currently gaining attention in the field of cardiovascular disease. Secoisolariciresinol diglucoside, a lignin derivative found in flaxseeds, is metabolized into mammalian lignans. Lignans have numerous biological effects. Flax lignans have an effect on the early warning indications of breast and colon carcinogenesis in animal models. Regular flaxseed consumption may affect total and lowdensity lipoprotein levels in the blood. Increase serum levels of the omega-3 fatty acids ALA and eicosapentaenoic acid, reduce inflammatory markers, and reduce postprandial glucose absorption. Flaxseed has demonstrated significant antioxidant and antiinflammatory properties in both animal and human research. In cases such as cardiovascular risk, certain types of cancer, and other metabolic disorders, a flaxseed supplement in the diet may be beneficial. Numerous studies have demonstrated the benefits of fresh flaxseed and flaxseed-based baked goods for maintaining health and preventing disease. This article focuses on the 'nutraceutical' potential of 'flaxseed' and its function as a 'medicine food' that is both therapeutic and preventative.

Antibiotic alternatives to produce organic poultry meat as a safe food source and the impact of its consumption on human health: A review

Abstract The scientific evidence on the effects of consuming organic chicken meat on human health is examined in this review article. Few studies particularly look at the effects of eating organic chicken meat on people’s health. Although the evidence is conflicting, they speculate that consuming organic chicken meat may reduce the incidence of obesity and allergy-related illnesses. Customers who purchase organic chicken meat generally have healthier eating habits. The significance of these discoveries for human health is unclear. Still, animal and poultry studies suggest that whether agriculture produces food from conventional or organic sources has different effects on early development and physiology. Omega-3 fatty acids and meat are more abundant in organic than in common meat. However, this is not nutritionally relevant compared to other dietary sources. The widespread use of pharmaceuticals is one of the primary drivers of antimicrobial resistance in traditional animal agriculture. It is possible to reduce this risk and potentially have significant positive effects on public health by preventing animal sickness and using antibiotics more sparingly, as is done in organic farming. The review highlights the importance of organic feeds as an effective and vital alternative to antibiotics in the poultry industry and their impact on human health.

Nutritional Value, Fatty Acid and Phytochemical Composition, and Antioxidant Properties of Mysore Fig (Ficus drupacea Thunb.) Fruits.

Ficus drupacea is a fruit-bearing tree that is distributed in Southeast Asia and Australia. The objective of this research was to ascertain the following with regard to ripened fruits: (i) their nutritional value, (ii) their mineral status, (iii) the fatty acid composition of fruit and seed oil, (iv) their phytochemical makeup, and (v) their antioxidant properties. The ripened fruits contained 3.21%, 3.25%, 0.92%, 1.47%, and 2.20% carbohydrate, protein, fat, ash, and fiber, respectively. Fruits had an energy content of 30.18 kcal/100 g. In terms of mineral content, the fruit was rich in potassium, magnesium, calcium, and nitrogen, with values of 21.03, 13.24, 11.07, and 4.13 mg/g DW. Iron, zinc, manganese, and boron had values of 686.67, 124.33, 114.40, and 35.78 µg/g DW, respectively. The contents of oxalate and phytate were 14.44 and 2.8 mg/g FW, respectively. The fruit and seed oil content were 0.67 and 8.07%, respectively, and the oil's physicochemical properties were comparable to those of fig fruit and seed oils. Omega-3 (α-linolenic acid), omega-6 (linoleic acid), and omega-9 (oleic acid) fatty acids were abundant in the oils. Fruit extracts in acetone, methanol, and water have greater concentrations of phenolics, flavonoids, and alkaloids. The 2,2-diphenyl-2-picrylhydrazyl, total antioxidant activity, and ferric reducing antioxidant power assays demonstrated increased antioxidant activities in close correlation with the higher concentrations of phenolics, flavonoids, and alkaloids. The results of this study demonstrate that the fruits of F. drupacea are a strong source of nutrients and phytochemicals, and they merit more investigation and thought for possible uses.

Can Omega-3 prevent the accidence of stroke: a mendelian randomization study

BackgroundThe lipid-lowering effects of Omega-3 fatty acids have been widely reported, yet their impact on ischemic stroke remains controversial. Reports on the protective effects of unsaturated fatty acids, such as Omega-6 and Omega-7, as well as saturated fatty acids in cardiovascular diseases, including hypertension and ischemic stroke, are less frequent.ObjectivesThis study aims to identify fatty acids associated with blood pressure and ischemic stroke through Mendelian randomization. Besides, it seeks to determine whether specific fatty acids can prevent ischemic stroke by managing blood pressure and revealing the specific mechanisms of this action.MethodsThis research involved downloading relevant data from websites and extracting SNPs that met the standard criteria as instrumental variables. Simultaneously, the ‘MR-PRESSO’ package and ‘Mendelian Randomization’ package were used to eliminate confounding SNPs that could bias the study results. Then, inverse variance weighting and the weighted median were employed as primary analysis methods, accompanied by sensitivity analysis to assess the validity of the causal relationships. Initially, multivariable Mendelian randomization was used to identify fatty acids linked to blood pressure and the incidence of ischemic stroke. The causal link between certain fatty acids and the initiation of ischemic stroke was then investigated using bidirectional and mediator Mendelian randomization techniques. Stepwise Regression and the Product of Coefficients Method in mediator Mendelian randomization were utilized to ascertain whether specific fatty acids reduce ischemic stroke risk by lowering blood pressure.ResultsMultivariable Mendelian randomization analysis indicated a potential inverse correlation between Omega-3 intake and both blood pressure and ischemic stroke. Consequently, Omega-3 was selected as the exposure, with blood pressure and ischemic stroke-related data as outcomes, for further bidirectional and mediation Mendelian Randomization analyses. Bidirectional Mendelian Randomization revealed that Omega-3 significantly influences DBP (P = 1.01e-04) and IS (P = 0.016). It also showed that DBP and SBP significantly affect LAS, SVS, CES, IS, and LS. Mediator Mendelian Randomization identified five established mediating pathways: Omega-3-Diastolic blood pressure-Small vessel stroke, Omega-3-Diastolic blood pressure-Cardioembolic stroke, Omega-3-Diastolic blood pressure-Lacunar stroke, Omega-3-Diastolic blood pressure-Large artery atherosclerosis stroke, and Omega-3-Diastolic blood pressure-Ischemic stroke. Of these, four pathways are complete mediation, and one pathway is partial mediation.ConclusionsThe findings suggest that Omega-3 may indirectly reduce the incidence of ischemic stroke by lowering blood pressure. Thus, blood pressure modulation might be one of the mechanisms through which Omega-3 prevents ischemic stroke. In summary, incorporating an increased intake of Omega-3 in the diet can serve as one of the dietary intervention strategies for patients with hypertension. Additionally, it can act as an adjunctive therapy for the prevention of ischemic strokes and their complications.

Eating for Optimization: Unraveling the Dietary Patterns and Nutritional Strategies in Endometriosis Management.

Endometriosis is a chronic gynecological disorder affecting millions of women worldwide, causing chronic pelvic pain, dyspareunia, dysmenorrhea, and infertility, and severely impacting their quality of life. Treatment primarily involves hormonal therapies and surgical excision, but high recurrence rates and the economic burden are substantial. With these challenges, significant discussion surrounds the potential role of dietary patterns in managing endometriosis, making it necessary to bridge this critical gap. This review investigates the current scientific evidence on the dietary patterns (eg, Mediterranean, vegetarian, anti-inflammatory, low-fermentable oligosaccharides, disaccharides, monosaccharides, and polyols [low-FODMAP], and Western-style diets) associated with endometriosis and provides a concise, yet thorough, overview on the subject. In addition, antioxidants, microbiota, and artificial intelligence (AI) and their potential roles were also evaluated as future directions. An electronic-based search was performed in MEDLINE, Embase, Cochrane Library, CINAHL, ClinicalTrials.gov, Scopus, and Web of Science. The current data on the topic indicate that a diet based on the Mediterranean and anti-inflammatory diet pattern, rich in dietary fiber, omega-3 fatty acids, plant-based protein, and vitamins and minerals, has a positive influence on endometriosis, yielding a promising improvement in patient symptoms. Preclinical investigations and clinical trials indicate that dietary antioxidants and gut microbiota modulation present potential new approaches in managing endometriosis. Also, AI may offer a promising avenue to explore how dietary components interact with endometriosis. Ultimately, considering genetic and lifestyle factors, a healthy, balanced, personalized approach to diet may offer valuable insights on the role of diet as a means of symptom improvement, facilitating the utilization of nutrition for the management of endometriosis.

Role of Omega-3 Fatty Acids in Improving Metabolic Dysfunctions in Polycystic Ovary Syndrome.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder that impacts women of reproductive age. In addition to reproductive and psychological complications, women with PCOS are also at a higher risk of developing metabolic diseases such as obesity, type 2 diabetes and cardiovascular disease. While weight reduction can help manage these complications in overweight or obese women, many weight loss interventions have been ineffective due to weight stigma and its psychological impact on women with PCOS. Therefore, exploring alternative dietary strategies which do not focus on weight loss per se is of importance. In this regard, omega-3 polyunsaturated fatty acids of marine origin (n-3 PUFAs), which are known for their hypotriglyceridemic, cardioprotective and anti-inflammatory effects, have emerged as a potential therapy for prevention and reversal of metabolic complications in PCOS. Several clinical trials showed that n-3 PUFAs can improve components of metabolic syndrome in women with PCOS. In this review, we first summarize the available clinical evidence for different dietary patterns in improving PCOS complications. Next, we summarize the clinical evidence for n-3 PUFAs for alleviating metabolic complications in PCOS. Finally, we explore the mechanisms by which n-3 PUFAs improve the metabolic disorders in PCOS in depth.

INVESTIGATION OF USAGE OPPORTUNITIES OF DIFFERENT PROPORTIONS OF WHEY AND CHIA SEED FLOUR IN BUTTERMILK

In this study, it was aimed to obtain a functional beverage with high nutritional value by using whey and chia seed flour in the production of buttermilk. In addition to its high nutritional value, while preventing whey from causing environmental pollution as a waste material, it is aimed to obtain a new dietary product with chia seed flour containing 34-40g fiber per 100g, antioxidant, omega-3 fatty acid and rich protein content. Experimental buttermilk samples were prepared by adding whey (PAS) and chia seed flour at different rates. K (control group), K2 (%1 Chia seed meal), K3 (%0,5 Chia seed meal), Group 1 (25% Whey + %1 Chia seed meal), Group 2 (25% Whey + %0,5 Chia seed meal), 3. Group (50% Whey + %1 Chia seed meal), 4.Experimental groups prepared as a group (50% Whey + %0,5 Chia seed flour) were kept at +4 ̊C and their physical, chemical and sensory properties were examined on the 1st, 3rd, 5th, 7th and 14th days. In the experimental buttermilk samples we researched, the use of whey and chia seed flour was found to have a significant effect on psychrophilic bacteria count (log cfu/ml), coliform group bacteria (log cfu/ml), yeast-mold count (log cfu/ml), lactobacil spp. (log cfu/ml) and lactococ spp. (log cfu/ml), pH, acidity (lactic acid), water-soluble dry matter (%), serum separation (%), color values (L*, a*, b*) and sensory properties (p
