#### Abnormal pancreolauryl tests in coeliac disease: lack of correlation with the degree of intestinal mucosal damage.

(BMJ, 1997-12-01)

Aims-To determine the frequency of abnormal pancreolauryl tests in untreated and treated adults with coeliac disease and to see whether abnormalities in treated coeliac patients correlate with the degree of recovery of ...

#### The o-specific polysaccharide chain of campylobacter fetus serotype a lipopolysaccharide is a partially o-acetylated 1,3-linked alpha-d-mannan

(Wiley-Blackwell, 1997-05-01)

A polysaccharide fraction liberated from Campylobacter fetus subsp. fetus serotype A lipopolysaccharide by mild acid hydrolysis followed by gel-permeation chromatography contained a partially O-acetylated D-mannan chain, ...

#### Very high‐energy observations of psr b1951+32

(IOP Publishing, 1997-11-01)

PSR B1951 + 32 is a gamma-ray pulsar detected by the Energetic Gamma Ray Experiment Telescope (EGRET) and identified with the 39.5 ms radio pulsar in the supernova remnant CTB 80. The pulsar energy spectrum is consistent ...

#### Boundary value problems for discrete equations

(Elsevier BV, 1997-07-01)

Two existence results are presented for second-order discrete boundary value problems. The first result is based on the notion of upper and lower solutions and the second result is based on the discrete Gelfand problem.

#### A general existence principle for strong solutions to the dirichlet problem for the equation δ u + f(t, u) = 0

(Elsevier BV, 1997-05-01)

An existence principle is established for Delta u + f(t, u) = 0 on Omega, u = 0 on partial derivative Omega. Our theory relies on a fixed point result for weakly sequentially continuous and weakly compact maps.

#### Multiwavelength observations of a flare from markarian 501

(IOP Publishing, 1997-10-01)

We present multiwavelength observations of the BL Lacertae object Markarian 501 (Mrk 501) in 1997 between April 8 and April 19. Evidence of correlated variability is seen in very high energy (VHE; E greater than or similar ...

#### Pulsed optical emission from psr 0656+14

(IOP Publishing, 1997-10-01)

Using data collected with the Special Astrophysical Observatory (SAG) 6 m telescope and the University College Galway (UCG) Transputer Instrument for Fast Image Deconvolution (TRIFFID) imaging photometer, we show that the ...

#### Crystallization and preliminary x-ray crystallographic analysis of the electron-transferring flavoprotein frommegasphaera elsdenii

(International Union of Crystallography (IUCr), 1997-07-01)

Electron-transferring flavoprotein from the rumen bacterium Megasphaera elsdenii is a heterodimer (M-r = 75 kDa) containing FAD as cofactor and functioning solely to mediate electron transfer between the prosthetic groups ...
