AIMS/INTRODUCTION: Atorvastatin is usually used to decrease the amount of fatty substances in individuals with type 2 diabetes mellitus. However, it can cause side effects, such as breakdown of skeletal muscle tissue. This study focuses on the effects of atorvastatin on autophagy of the skeletal muscles in diabetic rats. MATERIALS AND METHODS: Diabetes in rats in the diabetic (D) and atorvastatin (T) groups was induced using streptozotocin (65 mg/kg, intraperitoneal injection)...

BACKGROUND: Autologous fat grafting (AFG) is an important tool for plastic surgeons treating the aging face. Malar augmentation with fat is often targeted to restore the youthful facial contour and provides support to the lower eyelid. The existence of distinct facial fat compartments suggests a step-wise approach may be appropriate in this regard [1]. Here we describe a three-step approach to malar augmentation using targeted deep malar fat compartmental augmentation, termed the "Boomerang Lift"...

BACKGROUND: The latissimus dorsi flap is a popular choice for autologous breast reconstruction. To dramatically improve volume, we report our experience of using the immediately lipofilled extended latissimus dorsi (ELD) flap and show it as a valid option for autologous breast reconstruction. METHODS: Patients undergoing the procedure between December 2013 and June 2016 were included. Demographic, clinical and operative factors were analysed, together with in-hospital morbidity and duration of postoperative hospital stay...

Objectives: DCM has become one of the main reasons of death in diabetic patients. In this study, we aimed to explore the hawthorn leaf flavonoids (HLF) protective effect against diabetes-induced cardiac injury and the underlying mechanisms in experimental rats. Methods: Experimental diabetic model was induced by intraperitoneal injection of streptozotocin (STZ, 40 mg/kg) in rats after feeding with high-fat diet for 8 weeks. The diabetic rats received a 16-week treatment of different doses of HLF (50, 100, and 200)...

The brummer (bmm) genes encode the lipid storage droplet-associated triacylglycerols (TAG) lipases, which belong to the Brummer/Nutrin subfamily. These enzymes hydrolyze the ester bonds in TAG in lipid metabolism and act in insect energy homeostasis. Exposure to some agricultural chemicals leads to increased fecundity, which necessarily involves lipid metabolism, in some planthopper species. However, the biological roles of bmm in planthopper lipid storage and mobilization have not been investigated. Here, the open reading frame (ORF) of bmm (Nlbmm) was cloned and sequenced from the brown planthopper (BPH; Nilaparvata lugens)...

To better understand the effects of a diet high in fat, sugar, and sodium on cerebrovascular function, Sprague Dawley rats were chronically exposed to a Cafeteria diet. Resting cerebral perfusion and cerebrovascular reactivity were quantified using continuous arterial spin labeling (CASL) magnetic resonance imaging (MRI). In addition, structural changes to the cerebrovasculature and susceptibility to ischemic lesion were examined. Compared to control animals fed standard chow (SD), Cafeteria diet (CAF) rats exhibited increased resting brain perfusion in the hippocampus and reduced cerebrovascular reactivity in response to 10% inspired CO2 challenges in both the hippocampus and the neocortex...

OBJECTIVE: Angiotensin-converting enzyme 2 (ACE2) has been identified in pancreatic islets and can preserve β cells. In this study, we aimed to examine the possible role of ACE2 and its end product, angiotensin 1-7 (A1-7), in reducing β cell dedifferentiation during metabolic stress. METHODS: First, a lineage-tracing experiment was performed to track β cells in mice fed a high-fat diet (HFD). Second, the ACE2/A1-7 axis was evaluated in the HFD mouse model. Intraperitoneal glucose tolerance tests (IPGTTs) and intraperitoneal insulin tolerance tests (IPITTs) were conducted...

High-fat diet (HFD) and metabolic diseases cause detrimental effects on hippocampal synaptic plasticity, learning, and memory through molecular mechanisms still poorly understood. Here, we demonstrate that HFD increases palmitic acid deposition in the hippocampus and induces hippocampal insulin resistance leading to FoxO3a-mediated overexpression of the palmitoyltransferase zDHHC3. The excess of palmitic acid along with higher zDHHC3 levels causes hyper-palmitoylation of AMPA glutamate receptor subunit GluA1, hindering its activity-dependent trafficking to the plasma membrane...

Glucagon-like peptide-1 (GLP-1) injected into the brain reduces food intake. Similarly, activation of preproglucagon (PPG) cells in the hindbrain which synthesize GLP-1, reduces food intake. However, it is far from clear whether this happens because of satiety, nausea, reduced reward, or even stress. Here we explore the role of the bed nucleus of the stria terminalis (BNST), an area involved in feeding control as well as stress responses, in GLP-1 responses. Using cre-expressing mice we visualized projections of NTS PPG neurons and GLP-1R-expressing BNST cells with AAV-driven Channelrhodopsin-YFP expression...

Abelmoschus esculentus (AE), a commonly consumed vegetable, is well-known for its anti-hyperglycemic effects. However, few scientific reports have identified its targets because mucilage increases the difficulty of manipulation. We recently reported extraction steps to obtain subfractions of AE, which were found to attenuate the adverse effects of high glucose and fatty acid in vitro. In this study, we used modified extraction steps and type 2 diabetic rats to explore whether AE subfractions can improve the metabolic disturbances caused by insulin resistance in vivo...

Muscle atrophy results in severe functional impairment and is a significant clinical problem. We examined and characterized the therapeutic effects of autologous adipose-derived stem cells (ADCSs) using an in vivo muscle atrophy rat model. To identify the effect of injected ADSCs into muscle, we developed the following two models of muscle atrophy in rats: induction of denervation by sciatic nerve defects; and nerve repair after severing the sciatic nerve. The inguinal fat pads were harvested from each rat and autologous ADSCs were cultured and ADSCs were injected in the right hind limbs as the experimental group, while normal saline was injected in the left hind limbs, which served as the control group...

Accumulating evidence suggests that obesity is associated with chronic pain. However, whether obesity is associated with acute inflammatory pain is unknown. Using a well-established obese mouse model induced by a high-fat diet, we found that: (1) the acute thermal pain sensory threshold did not change in obese mice; (2) the model obese mice had fewer nociceptive responses in formalin-induced inflammatory pain tests; restoring the obese mice to a chow diet for three weeks partly recovered their pain sensation; (3) leptin injection induced significant phosphorylation of STAT3 in control mice but not in obese mice, indicating the dysmodulation of topical leptin-leptin receptor signaling in these mice; and (4) leptin-leptin receptor signaling-deficient mice (ob/ob and db/db) or leptin-leptin receptor pathway blockade with a leptin receptor antagonist and the JAK2 inhibitor AG 490 in wild-type mice reduced their nociceptive responses in formalin tests...

Gestational diabetes mellitus (GDM) is a growing health concern, and it increases the risk of adverse pregnancy outcomes with substantial long-term adverse health impacts on mothers and their offspring. Several studies have revealed specific associations between genetic variants and the risk of GDM. Single nucleotide polymorphisms (SNPs) are the major type of genetic variation in humans. Let-7 microRNA targets are enriched for genes containing SNPs associated with glucose metabolism, including Lin28. In the present study, the effect of T/C variants of rs3811463 (a SNP located near to the let-7 binding site in Lin28) on GDM risk was investigated...
