Adiabatic pulses for wideband inversion and broadband decoupling
TLDR
In this article, an inversion pulse for wideband application is obtained from a simple nonlinear amplitude modulation wherein the amplitude is modulated in accord with A(t)=A 0 {1-| sin βt| n } and the entire pulse is frequency modulated such that the phase varies as φ(t) =φ 0 + 1/2 kt 2About:

TL;DR: Adding periodic BIRD J-refocusing (BIRD=bilinear rotation decoupling) to data acquisition in an HSQC experiment causes broadband homonuclear decoupled, giving a single signal for each proton chemical shift.

Structure of a Hydroxyproline (Hyp)-Arabinogalactan Polysaccharide from Repetitive Ala-Hyp Expressed in Transgenic Nicotiana tabacum
TL;DR: This first complete structure of a Hyp-arabinogalactan polysaccharide is presented, showing that computer-based molecular modeling of Hyp-rich glycoproteins is now feasible and supports the suggestion that small repetitive subunits comprise larger arabinogAlactanpolysaccharides.

TL;DR: Investigation of the role of glutamine and alanine transport in the recycling of neurotransmitter glutamate was investigated in Guinea pig brain cortical tissue slices and prisms, and in cultured neuroblastoma and astrocyte cell lines, suggesting that neuronal system A may not play a prominent role in neurotransmitter cycling.
Journal ArticleDOI
Structure and interactions of the translation initiation factor eIF1
TL;DR: The solution structure of human eIF1 with an N‐terminal His tag is determined using NMR spectroscopy and GST pull‐down experiments show that eIF 1 binds specifically to the p110 subunit of eIF3, which explains how eif1 is recruited to the 40S ribosomal subunit.

Methods of, and apparatus for, proton decoupling in nuclear magnetic resonance spectroscopy
TL;DR: In this paper, a radio-frequency pulse is tuned to the frequency of the nuclear species, such as 1 H, to be decoupled or saturated and has a bandwidth adjusted to correspond to the entire chemical shift spectrum, minimizing the amount of radiofrequency power transmitted into a volume of the irradiated sample.

Method and apparatus for broadband decoupling in nuclear magnetic resonance with chirp pulses
Riqiang Fu,Geoffrey Bodenhausen +1 more
TL;DR: In this article, the authors proposed a method for broadband decoupling in nuclear magnetic resonance with chirp and other RF pulses, where the sample is placed in a static field, and a first cycle of chirps pulses are generated, followed by a second cycle of pulses generated by a supercycle of the first and second cycles.

Method for exciting transverse magnetization in magnetic resonance
TL;DR: In this article, a method for exciting transverse magnetization by irradiating a nuclear spin system subjected to a constant magnetic field with a frequency-modulated rf-pulse ("chirp"-pulse) and with a further frequency-modified rfpulse (further chirppulse), for refocusing the magnetization, is characterized in that the rf pulse-(P1) and the further pulse (P2) overlap each other in time at least partially.
