Mitochondrial trifunctional protein (TFP) deficiency is an inherited metabolic disorder of mitochondrial fatty-acid oxidation. Isolated long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency is often reported in Caucasian countries due to a common mutation. However, the molecular and clinical basis of complete TFP deficiency has not been extensively reported. In this study, 14 Japanese cases (13 families) with complete TFP deficiency, including 9 previously reported cases, were analyzed to clarify the clinical and molecular characteristics of TFP deficiency...

Aims—: Fibroblast growth factor-21 (Fgf21) is an endocrine factor that contributes to many physiological and pathological processes, mainly via its action as a metabolic regulator. Recent studies have shown that Fgf21 plays an important role in cardiac tissue. Pregnancy offers a physiological model of adaptive and reversible heart enlargement, but the molecular mechanisms underlying this cardiac hypertrophy are poorly understood. Therefore, the aim was to analyze the role of Fgf21 during late pregnancy, and assess the physiological relevance of Fgf21 for cardiac tissue during this process...

BACKGROUND: The pathogenesis of some types of preeclampsia is related to fatty acid oxidation disorders. Rapamycin can regulate fatty acid metabolism. This study aimed to investigate the effects of rapamycin on the clinical manifestations and blood lipid parameters in different preeclampsia-like mouse models. METHODS: Two preeclampsia-like mouse models and a control group were established: L-NA (injected with Nω-nitro-L-arginine methyl ester), LPS (injected with lipopolysaccharide), and the control group with normal saline (NS)...

The greatest risk of metabolic and infectious disease in dairy cows is during the transition from pregnancy to lactating (i.e., the transition period). The objective of this experiment was to determine the effects of extracellular vesicles (microvesicles involved in cell-to-cell signaling) isolated from transition cows on target cell function. We previously identified differences in the protein profiles of exosomes isolated from cows divergent in metabolic health status. Therefore, we hypothesized that these exosomes would affect target tissues differently...

Human pregnancy is associated with enhanced de novo lipogenesis in the early stages followed by hyperlipidemia during advanced gestation. Liver X receptors (LXRs) are oxysterol-activated nuclear receptors which stimulate de novo lipogenesis and also promote the efflux of cholesterol from extrahepatic tissues followed by its transport back to the liver for biliary excretion. Although LXR is recognized as a master regulator of triglyceride and cholesterol homeostasis it is unknown whether it facilitates the gestational adaptations in lipid metabolism...

Acute fatty liver of pregnancy (AFLP) is an obstetric emergency characterized by maternal liver failure and may have complications for the mother and fetus, including death. This review examines recent literature on the epidemiology, pathogenesis, diagnosis, and treatment of acute fatty liver of pregnancy. Pathogenesis of this disease has been linked to defects in fatty acid metabolism during pregnancy, especially in the setting of fetal genetic defects in fatty acid oxidation. The value of screening all patients for these genetic defects remains to be determined...

Liver diseases may be accompanied by profound changes in the hemostatic system including thrombocytopenia, decreased plasma levels of pro- and anticoagulants, and alterations in plasma levels of fibrinolysis. The net effect of the hemostatic changes in chronic and acute liver diseases is a hemostatic system that is in relative balance due to the simultaneous decline in pro- and antihemostatic drivers. A unique category of liver diseases are those induced by pregnancy. In acute fatty liver of pregnancy, profound hemostatic changes occur, which may be caused by a combination of liver failure and disseminated intravascular coagulation...

During a women's life cycle, pregnancy is a period in which she is at risk for hemorrhagic events and obstetrical syndromes that may develop into disseminated intravascular coagulation (DIC). This life-threatening condition is a complication of obstetrical and non-obstetrical causes including: (1) acute peripartum hemorrhage (uterine atony, cervical and vaginal lacerations, and uterine rupture); (2) placental abruption; (3) Pre-eclampsia/HELLP syndrome; (4) retained stillbirth; (5) sepsis; (6) amniotic fluid embolism; and (7) acute fatty liver of pregnancy...

OBJECTIVE: We present recurrent 2q13 microduplication in a family with autism spectrum disorder (ASD), intellectual disability, and liver disorder. CASE REPORT: A 45-year-old woman and her 52-year-old husband were referred for genetic counseling because of mental and liver disorders in their two sons and their planning for prenatal diagnosis of familial disorders in the future pregnancy. She and her husband were normal and healthy, but their 21-year-old elder son had suffered from ASD, severe intellectual disability, poor motor function, liver cirrhosis, and esophageal varices, and their 19-year-old younger son had suffered from ASD, mild intellectual disability, poor balance and coordination, hepatosplenomegaly, fatty liver, and mild liver cirrhosis...

Importance of calcium and vitamin D deficiency is well established in adult dyslipidemia. We hypothesized that maternal calcium and vitamin D deficiency could alter offspring's lipid metabolism. Our objective was to investigate the effect of maternal dietary calcium and vitamin D deficiency on lipid metabolism and liver function of the F1 generation offspring. intergenerational calcium-deficient (CaD) and vitamin D-deficient (VDD) models were developed by mating normal male rats with deficient females and continuing maternal-deficient diets through pregnancy and lactation...

Prenatal docosahexaenoic acid (DHA) supply is important to ensure an adequate infant neurodevelopment. Several fat supplements with DHA under different chemical structures are available. There is an increased placental phospholipase activity at the end of pregnancy. The hypothesis of this study was to discern whether DHA consumption during pregnancy as phospholipids (PLs) could be more available for placental DHA uptake and fetal accretion than triglycerides (TGs) form. We aimed to evaluate maternofetal DHA status in pregnant rats fed with DHA as PL from egg yolk or TG from algae oil to determine which source might be most effective during pregnancy...

Although we have been living in the era of biologic therapy for several decades, the use of immunomodulators (primarily thiopurines [azathioprine and mercaptopurine] and less so methotrexate) still remains an important component of the inflammatory bowel disease (IBD) pharmaceutical arsenal. Thiopurines as monotherapy exert corticosteroid-sparing effects and can maintain long-term remission in a considerable proportion of patients who have frequent relapses and are or have become mesalazine and/or corticosteroid intolerant or refractory...

Fatty liver disease is a common health problem of dairy cows occurring during the transition from pregnancy to lactation. It is a direct response to fat mobilization due to negative energy balance. Accumulation of lipids in the liver occurs if the uptake of non-esterified fatty acids by the liver exceeds the capacity of lipid oxidation or secretion by the liver. Currently, the diagnosis of fatty liver disease requires confirmation through biopsies to determine the hepatic lipid content. In view of this lack of a practical diagnostic tool, we compared the plasma lipidome of diseased dairy cows using liquid chromatography coupled to quadrupole time-of-flight mass spectrometry...

Feeding dairy calves at high intensity has been demonstrated to increase milk yield in later life. We investigated the effect of 3 different feeding regimens in the preweaning period on the metabolic and endocrine status during calfhood and in heifers at the onset of the first lactation. In trial 1, 57 German Holstein calves were allocated to 3 different feeding groups: milk replacer restricted to 6.78 kg/calf per day, 11.5% solids (MR-res, n = 20), milk replacer 13.8% solids, ad libitum (MR-ad lib, n = 17), and whole milk ad libitum (WM-ad lib, n = 20)...

Cinnamon has a history of use for medicinal purposes and its major benefits have been linked to cinnamaldehyde. The present study aimed to investigate the hypoglycemic action of cinnamaldehyde against fatty-sucrosed diet/streptozotocin (FSD/STZ)-rat model of gestational diabetes. Female albino rats were divided into three groups. Group I fed with normal diet (ND) while group II and III were fed with FSD for eight weeks (five weeks pre-gestational and three weeks gestational). Rats of group III were administered with a daily oral dose of 20mg/kg cinnamaldehyde one week before mating onward...

Nonalcoholic fatty liver disease (NAFLD) is widespread in adults and children. Early exposure to maternal obesity or Western-style diet (WD) increases steatosis and oxidative stress in fetal liver and is associated with lifetime disease risk in the offspring. Pyrroloquinoline quinone (PQQ) is a natural antioxidant found in soil, enriched in human breast milk, and essential for development in mammals. We investigated whether a supplemental dose of PQQ, provided prenatally in a mouse model of diet-induced obesity during pregnancy, could protect obese offspring from progression of NAFLD...

All women are at risk of acute and chronic liver diseases. Of particular importance are those diseases that exclusively affect pregnant women and have adverse effects on maternal, fetal, or neonatal outcomes. Acute viral hepatitis is an important cause of liver disease in pregnant women, and hepatitis E infection is associated with substantial mortality. An increasing number of women have chronic liver diseases caused by viral hepatitis, alcoholic liver disease and nonalcoholic fatty liver disease, autoimmune liver diseases, and genetic liver diseases...
