To investigate the etiopathogenesis of fatty liver hemorrhagic syndrome (FLHS) and the protective effects of soybean lecithin against FLHS in laying hens, 135 healthy 300-day-old Hyline laying hens were randomly divided into groups: control (group 1), diseased (group 2), and protected (group 3). Each group contained 45 layers with 3 replicates. The birds in these 3 groups were fed a control diet, a high-energy/low-protein (HELP) diet or the HELP diet supplemented with 3% soybean lecithin instead of maize. The fat percent in the liver was calculated...

Insulin-like Growth Factor I (IGF-I) induces adipogenesis in vitro. IGF Binding Protein 4 (IGFBP4) is highly expressed in adipocytes and osteoblasts and is inhibitory of IGFs in vitro. We previously reported that Igfbp4 null mice (Igfbp4-/-) had decreased fat proportions at 8 and 16 weeks of age. However, the mechanism leading to the reduced adiposity remains unknown. The purpose of this study was to elucidate how IGFBP4 mediates adipose tissue development in vivo. Our results showed that inguinal (iWAT) and gonadal (gWAT) white adipose tissues from Igfbp4-/- mice had decreased weights and Pparγ expression...

INTRODUCTION: Facial bone defects are frequently encountered problems in clinical practice. Bone grafts, flaps, and alloplastic materials are often used in their treatment. This leads to donor site morbidity and prolongation of the operation. The authors have planned this study to examine whether adipose tissue derived stromal vascular fraction (SVF) has an osteogenic effect in the critical sized membranous bone defect of the zygomatic bone. MATERIALS AND METHODS: Twenty male Wistar Albino rats were used...

Adipose cells have traditionally been viewed as a simple, passive energy storage depot for triglycerides. However, in recent years it has become clear that adipose cells are highly physiologically active and have a multitude of endocrine, metabolic, haematological and immune functions. Changes in the number or size of adipose cells may be directly implicated in disease (for example, in the metabolic syndrome), but may also be linked to other pathological processes such as inflammation, malignant infiltration or infarction...

Atherosclerosis, a serious threat to human cardiovascular health, involves inflammation throughout its various stages of development. MicroRNAs play an important regulatory role in macrophages that respond to inflammation, but the underlying mechanisms are largely unknown. In this work, we study the impact of miR-19a in macrophage-derived foam cell formation during atherogenesis. A microarray-based analysis of serums from patients with coronary heart disease in comparison with healthy controls reveals a significant enrichment of miR-19a in the serums of atherosclerosis patients...

Programmed death ligand 1 (PD-L1) is expressed on a number of immune and cancer cells, where it can downregulate antitumor immune responses. Its expression has been linked to metabolic changes in these cells. Here we develop a radiolabeled camelid single-domain antibody (anti-PD-L1 VHH) to track PD-L1 expression by immuno-positron emission tomography (PET). PET-CT imaging shows a robust and specific PD-L1 signal in brown adipose tissue (BAT). We confirm expression of PD-L1 on brown adipocytes and demonstrate that signal intensity does not change in response to cold exposure or β-adrenergic activation...

Cocoa polyphenols are thought to reduce the risk of cardiovascular diseases. Thus, cocoa-containing foods may have significant health benefits. Here, we studied the impact of chocolate liquor on vascular lesion development and plaque composition in a mouse model of atherosclerosis. Apolipoprotein E (apoE)-knockout mice were assigned to two groups and fed a Western diet that contained 250 g/kg of either chocolate liquor or a polyphenol-free isoenergetic control paste for 16 weeks. In addition to fat, protein and fibers, the chocolate liquor contained 2 g/kg of polyphenols...

OBJECTIVE: Recent evidence suggests an important role for angiotensin-converting enzyme 2 (ACE2) in limiting abdominal aortic aneurysm (AAA). This study examined the effect of ACE2 deficiency on AAA development and the efficacy of resveratrol to upregulate ACE2 in experimental AAA. APPROACH AND RESULTS: Ace2 deletion in apolipoprotein-deficient mice (ApoE(-/)(-)Ace2(-/y) ) resulted in increased aortic diameter and spontaneous aneurysm of the suprarenal aorta associated with increased expression of inflammation and proteolytic enzyme markers...

BACKGROUND: Kidney transplantation (KT) is the treatment option for patients with end stage renal disease (ESRD) to prolong survival and improve quality of life. Although the use of potent immunosuppressive agents increases graft survival in kidney transplantation recipients (KTRs), it may lead to the development of malignancy, including transitional cell carcinoma (TCC). TCC developing in the pelvis of graft kidney is very rare in KTRs. CASE PRESENTATION: A 40-year-old male visited hospital with complaints of nausea, vomiting and gross hematuria...

Type 2 diabetes remains one of the leading causes of death worldwide. Persistent hyperglycemia within a diabetic state is implicated in the generation of oxidative stress and aggravated inflammation that is responsible for accelerated modification of pancreatic beta cell structure. Here we investigated whether a lanosteryl triterpene, methyl-3β-hydroxylanosta-9,24-dien-21-oate (RA-3), isolated from Protorhus longifolia can improve glucose tolerance and pancreatic beta cell ultrastructure by reducing oxidative stress and inflammation in high fat diet and streptozotocin-induced type 2 diabetes in rats...

OBJECTIVES: Consuming a high-fat diet (HFD) may result in behavioral deficits similar to those observed in aging animals. Blueberries may prevent and even reverse age-related alterations in neurochemistry and behavior. It was previously demonstrated that middle-aged mice fed HFD had impaired memory; however, supplementation of HFD with blueberry reduced these memory deficits. As a follow-up to that study, the brain tissue from HFD-fed mice with and without blueberry supplementation was assessed to determine the neuroprotective mechanism(s) by which blueberry allayed cognitive dysfunction associated with HFD...

Uridine adenosine tetraphosphate (Up4A) exerts potent relaxation in porcine coronary arteries that is reduced following myocardial infarction, suggesting a crucial role for Up4A in the regulation of coronary flow (CF) in cardiovascular disorders. We evaluated the vasoactive effects of Up4A on CF in atherosclerosis using ApoE knockout (KO) mice ex vivo and in vivo. Functional studies were conducted in isolated mouse hearts using the Langendorff technique. Immunofluorescence was performed to assess purinergic P2X1 receptor (P2X1R) expression in isolated mouse coronary arteries...

Gut microbiota may not only affect composition of local immune cells but also affect systemic immune cells. However, it is not completely clear how gut microbiota modulate these immune systems. Here, we found that there exist expanded macrophage pools in huREG3γ (tgIEC) mice. REG3γ-associated Lactobacillus, which is homology to Lactobacillus Taiwanese, could enlarge macrophage pools not only in the small intestinal lamina propria but also in the spleen and adipose tissues. STAT3-mediated signal(s) was a critical factor in the Lactobacillus-mediated anti-inflammatory macrophages...

Muscle wasting, also known as cachexia, is associated with many chronic diseases, which worsens prognosis of primary illness leading to enhanced mortality. Molecular basis of this metabolic syndrome is not yet completely understood. SIRT6 is a chromatin-bound member of the sirtuin family, implicated in regulating many cellular processes, ranging from metabolism, DNA repair to aging. SIRT6 knockout (SIRT6-KO) mice display loss of muscle, fat and bone density, typical characteristics of cachexia. Here we report that SIRT6 depletion in cardiac as well as skeletal muscle cells promotes myostatin (Mstn) expression...

The BCL-2 family are crucial regulators of the mitochondrial pathway of apoptosis in normal physiology and disease. Besides their role in cell death, BCL-2 proteins have been implicated in the regulation of mitochondrial oxidative phosphorylation and cellular metabolism. It remains unclear, however, whether these proteins have a physiological role in glucose homeostasis and metabolism in vivo Here we report that fat accumulation in the liver increases JNK-dependent BIM expression in hepatocytes. To determine the consequences of hepatic BIM deficiency in diet-induced obesity, we generated liver-specific BIM knockout (BLKO) mice...
