BACKGROUND: Stromal vascular fraction (SVF) represents an attractive source of adult stem cells and progenitors, holding great promise for numerous cell therapy approaches. In 2017, it was reported that 1524 patients received autologous SVF following the enzymatic digestion of liposuction fat. The treatment was safe and effective and patients showed significant clinical improvement. In a collaborative study, we analyzed SVF obtained from 58 patients having degenerative, inflammatory, autoimmune diseases, and advanced stage cancer...

Highly inbred C57BL/6 mice show wide variation in their degree of insulin resistance in response to diet-induced obesity even though they are almost genetically identical. Here we employed transcriptional profiling by RNA sequencing (RNA-Seq) of visceral adipose tissue (VAT) and liver in young mice to determine how gene expression patterns correlate with the later development of high-fat diet (HFD)-induced insulin resistance in adulthood. To accomplish this goal, we partially removed and banked tissues from pubertal mice...

The different cell types of multicellular organisms have specialized physiological requirements, affecting also their mitochondrial energy production and metabolism. The genome of mitochondria is essential for mitochondrial oxidative phosphorylation (OXHPOS) and thus plays a central role in many human mitochondrial pathologies. Disorders affecting mitochondrial DNA (mtDNA) maintenance are typically resulting in a tissue-specific pattern of mtDNA deletions and rearrangements. Despite this role in disease as well as a biomarker of mitochondrial biogenesis, the tissue-specific parameters of mitochondrial DNA maintenance have been virtually unexplored...

DmCatD, a cathepsin D-like peptidase of the hematophagous insect Dipetalogaster maxima, is synthesized by the fat body and the ovary and functions as yolk protein precursor. Functionally, DmCatD is involved in vitellin proteolysis. In this work, we purified and sequenced DmCatD, performed bioinformatic analyses and investigated the events involved in its targeting and storage in developing oocytes. By ion exchange and gel filtration chromatography, DmCatD was purified from egg homogenates and its identity was confirmed by mass spectrometry...

BACKGROUND: Fetal fat is indicative of the energy balance within the fetus, which may be disrupted in pregnancy complications such as fetal growth restriction, macrosomia, and gestational diabetes. Water-fat separated MRI is a technique sensitive to tissue lipid content, measured as fat fraction (FF), and can be used to accurately measure fat volumes. Modified two-point Dixon and chemical shift encoded MRI (CSE-MRI) are water-fat separated MRI techniques that could be applied to imaging of fetal fat...

BACKGROUND: Epidemiological studies have described an "acculturation paradox." Increased acculturation to the United States is associated with increased consumption of dietary fat and decreased consumption of fruits/vegetables. OBJECTIVE: To expand understanding of the dietary acculturation paradox, this study examined how bicultural Mexican-American women construct ethnic identity and how these identities and identity-making processes relate to perceptions of health and nutrition...

Sleep disturbances are associated with various metabolic diseases such as hypertension and diabetes. We had previously established a mouse model of a psychophysiological stress-induced chronic sleep disorder (CSD) characterized by disrupted circadian rhythms of wheel-running activity, core body temperature, and sleep-wake cycles. To evaluate the underlying mechanisms of metabolic disorders induced by CSD, we created mice with CSD for six weeks and fed them with a high-fat diet. Glucose intolerance with hyperglycemia resulted, although plasma insulin levels and body weight increases were identical between control and CSD mice...

Monitoring phase transition in adipose tissue and formation of lipid crystals is important in Cryo-procedures such as Selective Cryolipolysis (SC). We exploited a Near-Infrared Spectroscopy (NIRS) method to monitor the onset of fat phase transition (freezing/melting) in human abdominal adipose tissue. The changes in optical scattering were compared to Differential Scanning Calorimetry (DSC) measurements as the gold standard method for measuring phase transition. For some samples, concurrent in vitro measurements of optical scattering using NIRS and the MR signal parameters (T2*) as well as spectral parameters using MR Spectroscopy were performed in a 3 T MR scanner during a cooling/heating cycle...

Recent discoveries of novel functions and diverse origins of lymphatic vessels have drastically changed our view of lymphatic vasculature. Traditionally regarded as passive conduits for fluid and immune cells, lymphatic vessels now emerge as active, tissue-specific players in major physiological and pathophysiological processes. Lymphatic vessels show remarkable plasticity and heterogeneity, reflecting their functional specialization to control the tissue microenvironment. Moreover, alternative developmental origins of lymphatic endothelial cells in some organs may contribute to the diversity of their functions in adult tissues...

Changes in mean and variance of gene expression with age have consequences for healthy aging and disease development. Age-dependent changes in phenotypic variance have been associated to a decline in regulatory functions leading to increase in disease risk. Here we investigate age-related mean and variance changes in gene expression measured by RNA-seq of fat, skin, whole blood and derived lymphoblastoid cell lines (LCLs) expression from 855 adult female twins. We see evidence of up to 60% of age effects on transcription levels shared across tissues, and 47% of those on splicing...

This study tested the hypothesis that extracorporeal shock wave (ECSW) therapy could protect mouse brain from chronic cerebral hypoperfusion (CHP)-induced neuropathological changes in a bilateral carotid arterial stenosis (CAS) model. Adult-male C57BL/6 (B6) mice (n=36) were randomized into group 1 (sham-control), group 2 (CHP) and group 3 [CHP+ECSW (100 impulses at 0.15 mJ/mm2) on day 5, 10 and 15 after CHP induction]. By day 60 after CHP induction, the white matter lesion, protein expressions of inflammatory (TNF-α/NF-κB/iNOS), oxidative-stress (NOX-1/NOX-2/NOX-4/nitrotyrosine), angiogenesis (eNOS/CD31), apoptotic (Bax/caspase-3/PARP), fibrotic (Smad3/TGF-ß) and mitochondrial-damaged (cytosolic cytochrome-C) biomarkers were significantly higher in group 2 than in groups 1 and 3, and significantly higher in group 3 than in group 1, whereas the protein expressions of anti-apoptotic (Bcl-2), anti-fibrotic (BMP-2/Smad1/5), and mitochondrial-integrity (mitochondrial cytochrome-C) biomarkers showed an opposite pattern to inflammation among the three groups (all P<0...

Background and objective: Hyperglycaemia remains a challenge in type 1 diabetes since current regimes used to determine meal insulin requirements prove to be ineffective. This is particularly problematic for meals containing high amounts of protein and fat. We aimed to determine the post-prandial glycaemic response and total insulin need for mixed meals, using sensor-augmented insulin pumps in children with type 1 diabetes. Methods: Twenty-two children with type 1 diabetes, aged 4-17 years on insulin pump therapy completed this home-based, cross-over, randomised controlled trial...
