  • (11) A 1977 Apple II computer sits in the background, near a poster that reads "Think" – presumably a nod to Apple's "Think different" advertising campaign of the late 1990s.
  • (12) Antibodies against both IAP and type C were detected in NOD, with the humoral response to type C, but not IAP, preceding decline in beta cell function.
  • (13) He was perhaps casting an envious glance at his counterpart Dave Whelan's summer signings, particularly Holt, who nodded over early on from six yards.
  • (14) Nicotinamide, a vitamin B group substance, has previously been shown to prevent diabetes and suppress insulitis in the NOD mouse.
  • (15) The study of animal models of insulin-dependent diabetes (BB rats, NOD mice) now allows demonstrating the autoimmune process.
  • (16) Here we show that the nodulation genes of this bacterium determine the production of a large family of Nod-factors which are N-acylated chitin pentamers carrying a variety of substituents.
  • (17) Nor is it good enough to listen, nod politely, then tell the troubled voters they've got it wrong.
  • (18) The NOD (non-obese diabetic) mouse spontaneously develops insulin-dependent diabetes mellitus (IDDM) characterized by autoimmune insulitis, involving lymphocytic infiltration around and into the islets followed by pancreatic beta (beta) cell destruction, similar to human IDDM.
  • (19) Treatment with anti-class II antibody effectively prevented the adoptive transfer of diabetes produced by splenocytes from diabetic NOD mice into newborn mice but failed to prevent adoptive transfer into irradiated adult NOD recipients.
  • (20) This time he looked like a nodding dog in the back of a car that's been in a terrible crash.

Nutation


Definition:

  • (n.) The act of nodding.
  • (n.) A very small libratory motion of the earth's axis, by which its inclination to the plane of the ecliptic is constantly varying by a small amount.
  • (n.) The motion of a flower in following the apparent movement of the sun, from the east in the morning to the west in the evening.
  • (n.) Circumnutation.

Example Sentences:

  • (1) The effect on the signal intensities of cerebrospinal fluid (CSF) and iophendylate (Pantopaque) and on CSF-iophendylate contrast was studied in vitro with a small-nutation-angle (alpha) gradient refocused magnetic resonance (MR) imaging technique (GRASS) as alpha, repetition time (TR), and echo time (TE) were varied.
  • (2) 2D 27Al nutation MAS NMR was used to corroborate the line assignment for the as-synthesized and the rehydrated AlPO4-17.
  • (3) The families that do not show consistent differences are not necessarily harbouring nutations at the same locus, or the same mutation at any particular locus.
  • (4) The mutation which makes T7 DNA sensitive to the endonuclease is separable from the amber nutation and located between am28 and am233 (gene 6).
  • (5) Solid-state 27Al NMR spectra of several aluminophosphate molecular sieves have been recorded with conventional magic-angle spinning (MAS), double-rotation (DOR) and quadrupole nutation with fast MAS.
  • (6) Enhanced resolution was obtained in the quadrupole nutation experiment at certain radiofrequency pulse strengths.
  • (7) There was a high correlation between measurements obtained with the variable nutation and partial saturation techniques.
  • (8) The one phase is the intermediate phase where dilatation of the cervix is almost complete and where there is an instinctive reflex that delivery is going to take place and this is very strong, and this is what starts off the oscillation (contra-nutation) of the sacrum and full engagement.
  • (9) The apparent T2 is influenced by the magnitude of the nutation angle inhomogeneity across the slice and paradoxically is not always more accurate with larger numbers of echoes.
  • (10) The accuracy of measurement of the spin-lattice relaxation time (T1) in biological systems using the variable nutation angle method is discussed using computer simulations.
