Influence of maternal dietary diversity during pregnancy on infant atopic dermatitis: Exploring the microbiome link in a Taiwanese birth cohort.

Background: Maternal diet during pregnancy plays a critical role in shaping infant immune development, potentially influencing the risk of atopic dermatitis. However, the underlying mechanisms remain unclear. This study examined the association between maternal dietary diversity during pregnancy and the incidence of atopic dermatitis in early childhood and explored the potential mediating role of the infant gut microbiome.

Distinct effects of methylglyoxal-derived hydroimidazolone 1, N-carboxyethyllysine, and an advanced glycation end product-rich diet on lipid metabolism, gut microbiota, and secondary bile acids in high-fat diet-induced obese mice.

Dietary advanced glycation end products (dAGEs) are implicated in oxidative stress, inflammation, and metabolic dysregulation. This study investigated the impact of methylglyoxal-derived hydroimidazolone 1 (MG-H), N-carboxyethyllysine (CEL), and a heated diet on metabolic health and gut microbiota in a high-fat diet (HFD)-induced obese mouse model. CEL and MG-H significantly reduced final body weight in HFD-fed mice, whereas the heated diet increased it.

Chronic sleep deprivation is associated with delayed puberty onset in rats, activation of proinflammatory cytokines and gut dysbiosis.

Chronic sleep deprivation (CSD) in adolescents has become a trend with adverse health outcomes. Previous studies have demonstrated that sleep deprivation causes inflammation, alters puberty onset, and changes the gut microbiome composition; however, the relationship between these is still unknown. Therefore, we hypothesized that CSD delays the onset of puberty elevating proinflammatory cytokines and alter ation of gut microbiome composition.

Exercise-induced weight loss modulates brain iron and omega-3 fatty acid metabolism in middle-aged obese rats.

Objectives: Midlife is a critical period for the onset of obesity and cognitive decline, which are often linked to disorders of iron and omega-3 long-chain polyunsaturated fatty acids (LCPUFAs). The aim was to investigate the effects of treadmill exercise on brain iron and LCPUFA metabolism.

Methods: Middle-aged male rats were fed either a control diet or a 50% high-fat diet (HFD), with or without iron enrichment (2 g ferric iron/kg diet), for 8 weeks to induce dysmetabolic iron overload syndrome (DIOS).

Treadmill intervention attenuates motor deficit with 6-OHDA-induced Parkinson's disease rat via changes in lipid profiles in brain and muscle.

One of the key hallmarks of Parkinson's disease is the disruption of lipid homeostasis in the brain, which plays a critical role in neuronal membrane integrity and function. Understanding how treadmill training impacts lipid restructuring and its subsequent influence on motor function could provide a basis for developing targeted non-pharmacological interventions for individuals living with early stage of PD. This study aims to investigate the effects of a treadmill training intervention on motor deficits induced by 6-OHDA in rats model of PD.

The Efficacy of Omega-3 Fatty Acids as the Monotherapy for Depression: A Randomized, Double-Blind, Placebo-Controlled Pilot Study.

Objective: Omega-3 polyunsaturated fatty acids (-3 PUFAs) have demonstrated protective effects in major depressive disorder (MDD) patients receiving antidepressant treatment. However, there have been a few double-blind randomized controlled trials focused on -3 PUFAs as monotherapy in MDD, and the outcomes have been mixed. This study aimed to assess the clinical effects of -3 PUFAs monotherapy in patients with MDD.

The Role of Dicer Phosphorylation in Gemcitabine Resistance of Pancreatic Cancer.

Dicer, a cytoplasmic type III RNase, is essential for the maturation of microRNAs (miRNAs) and is implicated in cancer progression and chemoresistance. Our previous research demonstrated that phosphorylation of Dicer at S1016 alters miRNA maturation and glutamine metabolism, contributing to gemcitabine (GEM) resistance in pancreatic ductal adenocarcinoma (PDAC). In this study, we focused on the role of Dicer phosphorylation at S1728/S1852 in GEM-resistant PDAC cells.

Insights into Metabolic Reprogramming in Tumor Evolution and Therapy.

Cancer remains a global health challenge, characterized not just by uncontrolled cell proliferation but also by the complex metabolic reprogramming that underlies its development and progression. This review delves into the intricate relationship between cancer and its metabolic alterations, drawing an innovative comparison with the cosmological concepts of dark matter and dark energy to highlight the pivotal yet often overlooked role of metabolic reprogramming in tumor evolution. It scrutinizes the Warburg effect and other metabolic adaptations, such as shifts in lipid synthesis, amino acid turnover, and mitochondrial function, driven by mutations in key regulatory genes.

Crosstalk between FTH1 and PYCR1 dysregulates proline metabolism and mediates cell growth in KRAS-mutant pancreatic cancer cells.

Ferritin, comprising heavy (FTH1) and light (FTL) chains, is the main iron storage protein, and pancreatic cancer patients exhibit elevated serum ferritin levels. Specifically, higher ferritin levels are correlated with poorer pancreatic ductal adenocarcinoma (PDAC) prognosis; however, the underlying mechanism and metabolic programming of ferritin involved in KRAS-mutant PDAC progression remain unclear. Here, we observed a direct correlation between FTH1 expression and cell viability and clonogenicity in KRAS-mutant PDAC cell lines as well as with in vivo tumor growth through the control of proline metabolism.

Lipidomics reveals ceramide biomarkers for detecting central precocious puberty in girls.

Background: Pubertal timing is modulated by complex interactions between the pituitary and gonadal sex steroid hormones. Evidence indicates that sphingolipids are involved in the biosynthesis of steroid hormones at multiple levels.

Method: This study recruited adolescent female patients from pubertal and pediatric endocrine clinics in Northern and Southern Taiwan from the Taiwan Puberty Longitudinal Study.

Essential trace element and phosphatidylcholine remodeling: Implications for body composition and insulin resistance.

Background: Recent studies indicated that bioactive lipids of phosphatidylcholines (PCs) and lysophosphatidylcholines (LysoPCs) predict unhealthy metabolic phenotypes, but results remain inconsistent. To fill this knowledge gap, we investigated whether essential trace elements affect PC-Lyso PC remodeling pathways and the risk of insulin resistance (IR).

Methods: Anthropometric and blood biochemical data (glucose, insulin, and lipoprotein-associated phospholipase A2 (Lp-PLA2)) were obtained from 99 adults.

Melatonin Ameliorates Neuropsychiatric Behaviors, Gut Microbiome, and Microbiota-Derived Metabolites in Rats with Chronic Sleep Deprivation.

With the increasing prevalence of sleep deprivation (SD)-related disorders, the effective treatment of sleep disorders has become a critical health research topic. Thus, we hypothesized and investigated the effectiveness of a 3-week melatonin intervention on neuropsychiatric behavioral responses mediated throughout melatonin receptors, gut microbiota, and lipid metabolites in rats with chronic SD. Eighteen 6-week-old Wistar rats were used and divided into the control grup (C, n = 6), SD group (n = 6), and melatonin-supplemented group (SDM, n = 6).

Roles of Omega-3 Polyunsaturated Fatty Acids in Managing Cognitive Impairment in Chronic Obstructive Pulmonary Disease: A Review.

Chronic obstructive pulmonary disease (COPD) contributes significantly to the death of people worldwide, especially the elderly. An essential feature of COPD is pulmonary inflammation, which results from long-term exposure to noxious substances from cigarette smoking and other environmental pollutants. Pulmonary inflammatory mediators spill over to the blood, leading to systemic inflammation, which is believed to play a significant role in the onset of a host of comorbidities associated with COPD.

Attenuation of Chronic Stress-Induced Depressive-like Symptoms by Fish Oil via Alleviating Neuroinflammation and Impaired Tryptophan Metabolism in Aging Rats.

The prevalence of depression is increasing, and geriatric depression, in particular, is difficult to recognize and treat. Depression in older adults is often accompanied by neuroinflammation in the central nervous system (CNS). Neuroinflammation affects the brain's physiological and immune functions through several pathways and induces depressive symptoms.

Omega-3 polyunsaturated fatty acids (n-3 PUFAs), somatic and fatigue symptoms in cardiovascular diseases comorbid major depressive disorder (MDD): A randomized controlled trial.

Introduction: Cardiovascular diseases (CVDs) and major depressive disorder (MDD) are the two most disabling diseases. Patients with CVDs comorbid depression had somatic and fatigue symptoms and were associated with chronic inflammation and omega-3 polyunsaturated fatty acid (n-3 PUFA) deficits. However, there have been limited studies on the effects of n-3 PUFAs on somatic and fatigue symptoms in patients with CVDs comorbid MDD.

Potential Hepatic Lipid Markers Associated with Nonalcoholic Steatohepatitis and Fibrosis in Morbid Obesity Patients.

This study investigated differences in lipidomic profile features in nonalcoholic steatohepatitis (NASH) between mild and significant liver fibrosis cases among patients with morbid obesity. Wedge liver biopsy was performed during sleeve gastrectomy and significant liver fibrosis was defined as a fibrosis score ≥ 2. We selected patients with NASH with non/mild fibrosis (stage F0-F1; = 30) and NASH with significant fibrosis (stage F2-F4; = 30).

Omega-3 Polyunsaturated Fatty Acids in Managing Comorbid Mood Disorders in Chronic Obstructive Pulmonary Disease (COPD): A Review.

Chronic obstructive pulmonary disease (COPD) is the third-leading cause of mortality globally, significantly affecting people over 40 years old. COPD is often comorbid with mood disorders; however, they are frequently neglected or undiagnosed in COPD management, thus resulting in unintended treatment outcomes and higher mortality associated with the disease. Although the exact link between COPD and mood disorders remains to be ascertained, there is a broader opinion that inflammatory reactions in the lungs, blood, and inflammation-induced changes in the brain could orchestrate the onset of mood disorders in COPD.
