In this study, the preclinical safety of an HIV-1 gp120 and mannose responsive microbicide delivery system (MRP) is evaluated in C57BL/6 mice. MRP was engineered through the layer-by-layer coating of calcium carbonate (CaCO3) with Canavalia ensiformis lectin (Con A) and glycogen. Read More

Bscl2 mice recapitulate many of the major metabolic manifestations in Berardinelli-Seip congenital lipodystrophy type 2 (BSCL2) individuals, including lipodystrophy, hepatosteatosis, muscular hypertrophy, and insulin resistance. Metabolic defects in Bscl2 mice with regard to glucose and lipid metabolism in skeletal muscle have never been investigated. Here, we identified Bscl2 mice displayed reduced intramyocellular triglyceride (IMTG) content but increased glycogen storage predominantly in oxidative type I soleus muscle (SM). Read More

Distinct metabolic adjustments arise from acclimation to constant hypoxia and intermittent hypoxia in estuarine killifish ().

J Exp Biol 2018 Dec 5;221(Pt 23). Epub 2018 Dec 5.

Department of Biology, McMaster University, Hamilton, Ontario, Canada, L8S 4K1.

Many fish experience daily cycles of hypoxia in the wild, but the physiological strategies for coping with intermittent hypoxia are poorly understood. We examined how killifish adjust O supply and demand during acute hypoxia, and how these responses are altered after prolonged acclimation to constant or intermittent patterns of hypoxia exposure. We acclimated killifish to normoxia (∼20 kPa O), constant hypoxia (2 kPa) or intermittent cycles of nocturnal hypoxia (12 h:12 h normoxia:hypoxia) for 28 days, and then compared whole-animal O consumption rates ( ) and tissue metabolites during exposure to 12 h of hypoxia followed by reoxygenation in normoxia.

Effects of dietary methionine restriction on postnatal growth, insulin sensitivity, and glucose metabolism in intrauterine growth retardation pigs at 49 and 105 days of age.

J Anim Sci 2018 Dec 2. Epub 2018 Dec 2.

College of Animal Science and Technology, Nanjing Agricultural University, Nanjing, China.

This study was conducted to investigate the effects of methionine restriction (MR) on growth performance, insulin sensitivity, and hepatic and muscle glucose metabolism in intrauterine growth retardation (IUGR) pigs at 49 and 105 days of age. At weaning (day 21), 30 female normal birth weight (NBW) piglets were fed control diets with adequate methionine (NBW-CON), whereas 60 female IUGR piglets were fed either the control diets (IUGR-CON) or MR diets which were 30% reduced in methionine (IUGR-MR) (n=6 replicates (pens) with 5 piglets/replicate). At 49 and 105 days of age, one pig with a body weight near to the mean of each replication was selected for biochemical analysis. Read More

Real-time simultaneous shim and motion measurement and correction in glycoCEST MRI using double volumetric navigators (DvNavs).

Magn Reson Med 2018 Dec 2. Epub 2018 Dec 2.

UCT Medical Imaging Research Unit, Division of Biomedical Engineering, Department of Human Biology, University of Cape Town, Cape Town, South Africa.

Purpose: CEST MRI allows for indirect detection of molecules with exchangeable protons, measured as a reduction in water signal because of continuous transfer of saturated protons. CEST requires saturation pulses on the order of a second, as well as repeated acquisitions at different offset frequencies. The resulting extended scan time makes CEST susceptible to subject motion, which introduces field inhomogeneity, shifting offset frequencies and causing distortions in CEST spectra that resemble true CEST effects.

The rice blast fungus Magnaporthe oryzae poses a great threat to global food security. During its conidiation (asexual spore formation) and appressorium (infecting structure) formation, autophagy is induced, serving glycogen breakdown or programmed cell death function, both essential for pathogenicity. Recently, we identified an M. Read More
