We have created a new benchmarking dataset for testing non-rigid 3D shape retrieval algorithms, one that is much more challenging than existing datasets. Our dataset features exclusively human models, in a variety of body shapes and poses. 3D models of humans are commonly used within computer graphics and vision, and so the ability to distinguish between(More)
Covalent modification of DNA distinguishes cellular identities and is crucial for regulating the pluripotency and differentiation of embryonic stem (ES) cells. The recent demonstration that 5-methylcytosine (5-mC) may be further modified to 5-hydroxymethylcytosine (5-hmC) in ES cells has revealed a novel regulatory paradigm to modulate the epigenetic(More)
Pyruvate carboxylase (PC) or pyruvate dehydrogenase (PDH) is required to transfer carbons from pyruvate into the Krebs cycle. PC activity is preserved in the islets of obese animals, but it is reduced in the islets of animal models of type 2 diabetes, suggesting that PC is important in beta cell adaptation to insulin resistance and that PC reduction may(More)
Functional MRI of the spinal cord is challenging due to the small cross section of the cord and high level of physiological noise. Though blood oxygenation level-dependent (BOLD) contrast has been used to study specific responses of the spinal cord to various stimuli, it has not been demonstrated using a controlled stimulus. In this paper, we use(More)
A study was conducted to investigate the effects of l-arginine (Arg) on performance and immune function in cyclophosphamide (CY) immunosuppressed weaned pigs. The weaned pigs were allotted randomly into one of three treatments, including: (1) non-challenged control; (2) CY-challenged group; and (3) CY + 0.5% Arg. On days 14 and 21 of the trial, pigs were(More)
The pyruvate–malate shuttle is a metabolic cycle in pancreatic beta cells and is important for beta cell function. Cytosolic malic enzyme (ME) carries out an essential step in the shuttle by converting malate to pyruvate and generating NADPH. In rat islets the pyruvate–malate shuttle may regulate insulin secretion and it has been shown to play a critical(More)
Aims/hypotheses. Type I (insulin-dependent) diabetes mellitus results from T-cell-mediated autoimmune destruction of pancreatic beta cells. Among the beta-cell autoantigens that have been implicated in triggering of beta-cell-specific autoimmunity, glutamic acid decarboxylase (GAD) is a strong candidate in both humans and the NOD mouse. We aimed to(More)
Bone marrow-derived mononuclear cells (BMNCs) have been shown to effectively treat ischemic cardiovascular diseases. Because diabetic neuropathy (DN) is causally associated with impaired angiogenesis and deficiency of angiogenic and neurotrophic factors in the nerves, we investigated whether DN can be ameliorated by local injection of BMNCs. Severe(More)
