Identification and properties of intense star-forming galaxies at redshifts z > 10
Surveys with the James Webb Space Telescope (JWST) have discovered candidate galaxies in the first 400 Myr of cosmic time. Preliminary indications have suggested these candidate galaxies may be more massive an...

Detection of intergalactic ionized helium absorption in a high-redshift quasar
Observations obtained with the recently refurbished Hubble Space Telescope reveal strong absorption arising from singly ionized helium along the line of sight to a high-redshift quasar. The strength of the abs...

Blue stragglers in the core of the globular cluster 47 Tucanae
High-resolution observations of the core of the globular cluster 47 Tucanae with the Faint Object Camera on the Hubble Space Telescope reveal a high density of 'blue straggler' stars, occupying the upper end o...

An investigation of new commercial samples of Methyl Green and Pyronin Y
New commercial samples of Methyl Green (Gurr Certistain), Pyronine G (Gurr Certistain) and Pyronin Y (Polysciences) have been investigated using spectrophotometry, thin layer chromatography and nuclear magneti...

Comparisons of the fertilizing and liming properties of lime-treated sewage sludge with its incinerated ash
Two field experiments were conducted to compare the fertilizing and liming properties of dried lime-treated sewage sludge with its incineration product (ash). One experiment used a mixture of ryecorn and ryegr...

Fertilizer and liming value of lime-treated sewage sludge
A field experiment was conducted with lucerne on a strongly acidic and phosphorus deficient soil to determine the liming and phosphorus and nitrogen fertilizer value of an undigested, lime-treated sewage sludg...

Nucleic acid staining with the methyl green-pyronin method
We compared the staining obtained using commercially available pyronin Y samples with that obtained using pure pyronin Y in a standardized methyl green-pyronin procedure. In addition, the importance of the dye...

Standardized Methyl Green—Pyronin Y procedures using pure dyes
Fully standardized Methyl Green—Pyronin methods are presented. Pure Pyronin Y and purified Methyl Green or Ethyl Green are used either simultaneously in one dye bath or are used as a sequence of Pyronin Y and ...

Nitrogen-induced boron deficiency in lucerne
In a glasshouse experiment with a boron deficient soil the application of nitrogen was found to decrease the boron concentration and boron uptake by lucerne (Medicago sativa). Without added boron, nitrogen applic...

Reversal of cerebral arterial spasm by intrathecal administration of a calcium antagonist (nimodipine)
Specific antagonists to the influx of calcium, necessary for the excitation-contraction coupling process in arterial smooth muscle, are potentially useful in the treatment of cerebral vasospasm but systemic hy...

Preparation and characterization of methyl green tetrafluoroborate
Commercial methyl green dyes were converted to tetrafluoroborate by means of NaBF4-solution, the compounds thus obtained were analytically pure. It was shown to be possible to distinguish between a “methyl” and a...

Spectrophotometric characteristics and assay of pure pyronin Y
The spectrophotometric characteristics of analytically pure pyronin Y have been investigated. Addition of metal ions (Fe3+, Zn2+, and Mg2+) and of dextrin were shown not to influence the absorption characteristic...

Plasma levels of sulfinpyrazone and of two of its metabolites after a single dose and during the steady state
The pharmacokinetics of sulfinpyrazone, and the plasma levels of its sulfide and sulfone metabolites, have been determined after a single oral dose (400 mg) and during steady-state conditions (4×200 mg daily f...

Clinical Pharmacokinetics and Potentially Important Drug Interactions of Sulphinpyrazone
Sulphinpyrazone is a derivative of Phenylbutazone. It was originally introduced as a uricosuric agent but in recent years it has been investigated for effects on platelet function.
