It is unknown whether insulin therapy can delay or prevent diabetes in nondiabetic relatives of patients with diabetes.
Examination of the histocompatibility region nonobese diabetic (NOD) mouse with antibodies against class II glycoproteins (products immune response genes major complex I-A and I-E), hybrid T-cell clones, mixed-lymphocyte cultures analysis restriction fragment length polymorphisms indicate that NOD has a unique no expression surface I-E, messenger RNA for I-E α , an not recognized by any monoclonal or clones studied. In crosses mice control C3H mice, development diabetes was dependent on...
Hydrodynamical cosmological simulations are increasing their level of realism by considering more physical processes and having greater resolution or larger statistics. However, usually either the statistical power such reached within galaxies sacrificed.

Twenty-one intravenous (i.v.) glucose tolerance tests were performed on nine subjects before the onset of overt type I diabetes mellitus. Islet cell antibodies (6 9 subjects) and elevated levels la-positive T-lymphocytes (3 3 studied) detected during prediabetic period.

Approximately 50% of Wistar “BB” rats spontaneously develop overt diabetes mellitus characterized by loss β-cells and “insulitis.” To define abnormalities immunoregulation in these rats, we quantitated their major circulating lymphocyte subsets.

Our statistical understanding of galaxy evolution is fundamentally driven by objects that lie above the surface-brightness limits current wide-area surveys (mu ~ 23 mag arcsec^-2). While both theory and small, deep have hinted at a rich population low-surface-brightness galaxies (LSBGs) fainter than these limits, their formation remains poorly understood. We use Horizon-AGN, cosmological hydrodynamical simulation to study how LSBGs, in particular ultra-diffuse (UDGs; mu > 24.5 arcsec^-2),...
Massive black hole (MBH) coalescences are powerful sources of low-frequency gravitational waves. To study these events in the cosmological context we need to trace large-scale structure and cosmic evolution a statistical population galaxies, from dim dwarfs bright galaxies. cover such large range galaxy masses, analyse two complementary simulations: Horizon-AGN with volume low resolution which tracks high-mass (> 1e7 Msun) MBH population, NewHorizon smaller but higher that traces low-mass (<...
Tidal features in the outskirts of galaxies yield unique information about their past interactions and are a key prediction hierarchical structure formation paradigm. The Vera C. Rubin Observatory is poised to deliver deep observations for potentially millions objects with visible tidal features, but inference galaxy interaction histories from such not straightforward. Utilising automated techniques human visual classification conjunction realistic mock images produced using NEWHORIZON...
Monomethoxy-capped oligo(ethylene oxide) methacrylate (OEGMA) is readily polymerised in aqueous media by atom transfer radical polymerisation at 20 °C using various initiators; the resulting OEGMA polymers and macromonomers were obtained high yield (>95%) within short reaction times polydispersities as low 1.12.

In the standard Lambda-CDM paradigm, dwarf galaxies are expected to be dark-matter-rich, as baryonic feedback is thought quickly drive gas out of their shallow potential wells and quench star formation at early epochs. Recent observations local dwarfs with extremely low dark matter content appear contradict this picture, potentially bringing validity model into question. We use NewHorizon, a high-resolution cosmological simulation, demonstrate that sustained stripping matter, in tidal...
Low-surface-brightness galaxies (LSBGs) -- defined as systems that are fainter than the surface-brightness limits of past wide-area surveys form overwhelming majority in dwarf regime (M* < 10^9 MSun). Using NewHorizon, a high-resolution cosmological simulation, we study origin LSBGs and explain why at similar stellar mass show large observed spread surface brightness. New Horizon populate well-defined locus brightness plane, with ~3 mag arcsec^-2, agreement deep SDSS Stripe data. Galaxies...

Comparison a control sample, matched stellar mass redshift, indicates that controls reside similar environments, show star-formation rates (which trace gas availability) exhibit comparable incidence of tidal features indicate recent interactions). explore properties by combining predicted conditions dwarfs cosmological hydrodynamical...

ABSTRACT The ‘core-cusp’ problem is considered a key challenge to the ΛCDM paradigm. Haloes in dark matter only simulations exhibit ‘cuspy’ profiles, where density continuously increases towards centre. However, profiles of many observed galaxies (particularly dwarf regime) deviate strongly from this prediction, with much flatter central regions (‘cores’). We use NewHorizon (NH), hydrodynamical cosmological simulation, investigate core formation, using statistically significant number...
We use a complete, unbiased sample of 257 dwarf (10^8 MSun < Mstar 10^9.5 MSun) galaxies at z 0.08, in the COSMOS field, to study morphological mix population low-density environments. Visual inspection extremely deep optical images and their unsharp-masked counterparts reveals three principal classes. 43 45 per cent dwarfs exhibit traditional `early-type' (elliptical/S0) `late-type' (spiral) morphologies respectively. However, 10 populate `featureless' class, that lacks both central light...
The e.s.r. spectra of a variety silyl radicals have been observed during the steady-state photolysis di-t-butyl peroxide in parent silane. In number cases, addition to proton hyperfine interactions, splittings from 29Si natural abundance observed. Unlike analogous alkyl radicals, are non-planar around atom bearing unpaired electron. series (Me)nSiH3–n probably become less planar as Me is replaced by H.
ABSTRACT Dwarf galaxies (M⋆ &lt; 109 M⊙) are key drivers of mass assembly in high-mass galaxies, but relatively little is understood about the dwarf themselves. Using NewHorizon cosmological simulation (∼40 pc spatial resolution), we investigate how mergers and fly-bys drive structural evolution around 1000 field group dwarfs up to z = 0.5. We find that, while often exhibit disturbed morphologies (5 20 per cent at 1 3 respectively), only a small proportion morphological disturbances seen...
