This study aimed to evaluate the effect of two methods of local application of alendronate and parathyroid hormone (PTH) on bone repair and the systemic implications. A critically sized defect (5 mm) was created in the cranial region of twenty-five male Wistar rats, and the bone removed was particulated, and grafted back to the defect with different treatments. The animals were randomly divided into five groups: A1- bone graft immersion in alendronate solution (3 mg/kg) for 5 minutes; P1- bone graft immersion in PTH solution (20 µg); A2- weekly local applications of alendronate 1 mg/kg; P2- weekly local applications of PTH (20 µg); C- no drugs were used...

Lack of sleep incurs physiological costs that include increased inflammation and alterations in the hypothalamic-pituitary-adrenal axis. Specifically, sleep restriction or deprivation leads to increased pro-inflammatory cytokine expression and elevated glucocorticoids in rodent models, but whether birds exact similar costs is unknown. In this study, we examined whether zebra finch (Taeniopygia guttata), an avian model species, exhibits physiological costs of sleep loss by using a novel automated sleep fragmentation/deprivation method, wherein a horizontal wire sweeps across a test cage to disrupt sleep every 120 s...

In non-alcoholic fatty liver disease (NAFLD), triglycerides accumulate within the liver because the rates of fatty acid accrual by uptake from plasma and de novo synthesis exceed elimination by mitochondrial oxidation and secretion as VLDL-triglycerides. Thioesterase superfamily member 2 (Them2) is an acyl-CoA thioesterase that catalyzes the hydrolysis of fatty acyl-CoAs into free fatty acids plus CoASH. Them2 is highly expressed in the liver, as well as other oxidative tissues. Mice globally lacking Them2 are resistant to diet-induced obesity and hepatic steatosis, and exhibit improved glucose homeostasis...

A crucial component of non-alcoholic fatty liver disease (NAFLD) pathogenesis is lipid stress, which may contribute to hepatic inflammation and activation of innate immunity in the liver. However, little is known regarding how dietary lipids, including fat and cholesterol, may facilitate innate immune activation in vivo. We hypothesized that dietary fat and cholesterol drive NAFLD progression to steatohepatitis and hepatic fibrosis by altering the transcription and phenotype of hepatic macrophages METHODS: This hypothesis was tested by using RNA-seq methods to characterize and analyze sort-purified hepatic macrophage populations that were isolated from mice fed diets with varying amounts of fat and cholesterol RESULTS: The addition of cholesterol to a high fat diet triggered hepatic pathology reminiscent of advanced non-alcoholic steatohepatitis (NASH) in humans characterized by signs of cholesterol dysregulation, generation of oxidized LDL, increased recruitment of hepatic macrophages, and significant fibrosis...

Although nonalcoholic steatohepatitis (NASH) is an important component of the metabolic syndrome, scavenger receptor CD36 also modulates NASH development. This study aimed to clarify whether exercise training suppresses CD36 expression in a mouse model of NASH. Male C57BL/6 mice were divided into four groups: normal diet (ND) sedentary, ND exercise, high-fat diet and high-fructose water (HFF) sedentary, and HFF exercise groups. The exercise groups were trained on a motorized treadmill at running speeds of 15-20 m/min for 60 min/day, 5 times/week for 16 weeks...

Pistachios contain beneficial substances such as unsaturated fatty acids, phytosterols, and polyphenols. In the present study, we investigated if pistachio consumption is able to prevent or to revert hyperglycemia, dyslipidemia, hepatic steatosis, and adipose tissue morphological alterations caused by high fat diet (HFD) in the mouse. Moreover, the impact of pistachio intake on the mRNA expression of peroxisome proliferator-activated receptor γ ( PPAR-γ ), fatty acid transport proteins ( FAT-P ), fatty acid synthase ( FAS ), stearoyl-CoA desaturase ( SCD1 ), and sterol regulatory element-binding transcription factor-1c ( SREBP-1c ) in liver and adipose tissue was also analyzed...

Formula-fed infants present higher cholesterol synthesis rates and lower circulating cholesterol during the postnatal feeding period compared to breast-fed infants, though the mechanisms underlying this phenotype are not fully understood. Typical infant formulas contain vegetable-based fats, inherently including phytosterols (PS), which are structurally similar to cholesterol and may interfere with their absorption. A seven-day old piglets model was used to test the inhibitory effects of PS on cholesterol absorption during postnatal feeding...

The role of estrogen receptor alpha (ERα) signaling in immunometabolic function is established in females. However, its necessity in males, while appreciated, requires further study. Accordingly, we first determined whether lower metabolic function in male mice compared to females is related to reduced ERα expression. ERα protein expression in metabolically active tissues was lower in males than females and this lower expression was associated with worse glucose tolerance. Second, we determined if ERα is required for optimal immunometabolic function in male mice consuming chow diet...

SCOPE: Dietary methionine restriction (MR) promotes multi-faceted health benefits. Moreover, lower rate of protein synthesis by dietary MR is associated with life span extension. The goal of this work is to explore how dietary MR would affect protein metabolism in a mouse model of high-fat diet-induced obesity (DIO). METHODS AND RESULTS: DIO mice (male C57BL/6) were subjected to dietary MR for 22 weeks. High-throughput sequencing technology, qRT-PCR analysis, and the dual luciferase reporter assay were performed to verify that MiR-328-3p directly targets cystathionine γ-lyase (CSE) to modulate endogenous H2 S production...

Background Liver cancer is the sixth most common cancer worldwide and the second leading cause of cancer mortality. Chronic liver disease caused by viral infection, alcohol abuse, or other factors can lead to cirrhosis. Cirrhosis is the most important clinical risk factor for hepatocellular carcinoma (HCC) whereby the normal hepatic architecture is replaced by fibrous septa and a spectrum of nodules ranging from benign regenerative nodules to HCC, each one of them with different imaging features. Conclusions Furthermore, advanced techniques including the quantification of hepatic and intralesional fat and iron, magnetic resonance elastography, radiomics, radiogenomics, and positron emission tomography (PET)-MRI are highly promising for the extraction of new imaging biomarkers that reflect the tumor microenvironment and, in the future, may add decision-making value in the management of patients with HCC...

Glucagon-like peptide-1 (GLP-1) has a broad spectrum of biological activity by regulating metabolic processes via both the direct activation of the class B family of G protein-coupled receptors and indirect nonreceptor-mediated pathways. GLP-1 receptor (GLP-1R) agonists have significant therapeutic effects on non-alcoholic fatty liver disease (NAFLD) and steatohepatitis (NASH) in animal models. However, clinical studies indicated that GLP-1 treatment had little effect on hepatic steatosis in some NAFLD patients, suggesting that GLP-1 resistance may occur in these patients...
