Objectives: The aim of the present study was to analyze the possible changes caused by the maternal ingestion of different types of fatty acids during pregnancy in the proinflammatory state in the odontogenesis of the fetuses.
Subject And Methods: Twenty-four jaws (n = 6 per group) of Wistar rats were collected on the 20th day of intrauterine life. Mothers were separated on the first day of pregnancy into 4 groups according to diet, as described below: control group (C) - diet with soy oil as a source of fat; saturated fatty acid group (S) - diet with lard in saturated fatty acids; trans-fatty acid group (T) - diet with vegetable fat, rich in trans-saturated fatty acids; and polyunsaturated fatty acid (PUFA) group - diet with fish oil, rich in PUFAs.
Results: Microscopic analysis showed no alterations in tissue development of the teeth between the groups with different lipid diets (T, S, and PUFA) when compared to the control group (C); immunohistochemical analysis for the expression of JAK2, STAT3, P-STAT3, SOCS3, and IL-6 showed no statistically significant difference (p > 0.05) compared to the control group. However, there were changes (p < 0.05) between the T group and the PUFA group in the expression of JAK2.
Conclusion: Thus, lipid consumption in the maternal diet remains a topic to be explored in embryonic development, despite not causing morphological changes to the tooth germ of rats.

Background: Atherosclerosis (AS) is a major contributor to vascular disorders and represents a significant risk to human health. Currently, first-line pharmacotherapies are associated with substantial side effects, and the development of atherosclerosis is closely linked to dietary factors. This study evaluated the effects of a dietary supplement, EsV3, on AS in apolipoprotein E (ApoE) model mice.

To explore the changes and significance of resolvin D1 (RvD1) in the treatment of systemic lupus erythematosus (SLE) with Belimumab. The clinical data from patients with moderate to severe disease activity SLE who received oral stable doses of glucocorticoids (≤10 mg/d) and/or immunosuppressants for more than 3 months at the outpatient or inpatient department of the First Affiliated Hospital of Soochow University from January 2022 to November, 2023 were retrospectively collected. All patients were treated with 10 mg/kg intravenous infusion of Belimumab.

Endurance is an equestrian discipline that primarily relies on aerobic metabolism. Intense aerobic exercise produces reactive oxygen species due to an imbalance between oxidant and antioxidant substances, known as oxidative stress, which may reduce athletic performance. This study evaluated the effects of a feed supplement containing natural antioxidants and omega-3 fatty acids on the blood antioxidant activity and the athletic condition of endurance horses undergoing an exercise test.

Background And Aims: Alcohol Use Disorder (AUD) is a psychiatric disorder characterized notably by gut microbial dysbiosis and insufficient dietary fiber intake. This study aims to investigate the effect of dietary fiber placebo-controlled intervention in patients suffering from AUD during a three-week period of alcohol withdrawal, in order to discover microbial-derived metabolites that could be involved in metabolic and behavioral status.
Methods: A randomized, double-blind, placebo-controlled study was performed with 50 AUD patients supplemented with inulin (prebiotic dietary fiber) or maltodextrin (placebo) during 17 days.
