Background: Radium-226 (226Ra) is a product of the 238U radionuclide decay series that significantly incorporated into the human body through water intake. It can also potentially cause a series of health problems including cancers of the digestive system.

Hydralazine has been used for the treatment of hypertension since 1950 (Gross et al., 1950), but only since the introduction of beta-adrenoceptor blocking agents has its use again become popular (Koch-Weser, 1976). Originally, hydralazine was given in four divided doses, but it has been shown to be equally effective and without increased side-effects when given by twice daily dosage (O'Malley e...

We show that the strong coupling phase of the non-Abelian Thirring model is dual to the weak-coupling phase of a system of two WZNW models coupled to each other through a current-current interaction. This latter system is integrable and is related to a perturbed conformal field theory which, in the large |k| limit, has a nontrivial zero of the perturbation-parameter beta-function. The non-Abeli...

INTRODUCTION Extramedullary hematopoiesis in the kidney and adrenal are rarely reported in medical literature and are usually found as incidentaloma. It usually occurs in patients with hematologic disorder such as thalassemia. CASE PRESENTATION The patient was a 23-year-old Iranian man with beta thalassemia who was admitted with a suprarenal mass. Adrenal mass was detected by ultrasonography ...

Forty-seven strains of Citrobacter diversus were isolated during a 12-month period from clinical material obtained from patients in a general hospital in Israel. The majority of cultures (38) were recovered from urine and wound discharges. There was one case of septicemia. The biochemical reactions of all cultures were typical for this species, except one that was anaerogenic, and they could be...

A Mycoplasma hyopneumoniae clone bank was screened with hyperimmune pig serum. One clone exhibited sequence homology to the prokaryotic R2 subunit of ribonucleotide reductase and was expressed as an 11-kDa protein fused to beta-galactosidase. The vaccine potential of the fusion protein was assessed in pig trials. Following experimental challenge with a virulent isolate of M. hyopneumoniae, gros...

The results of a detailed solid state and solution structural study of the Fe(III) bis-mida complex [Fe(III)(mida)(2)]- (mida = N-methyl-iminodiacetate) are reported. The structure of the sodium salt Na[Fe(mida)2][NaClO4]2.3H2O (1) was determined by single-crystal X-ray analysis. The complex anion in 1 contains a six-coordinate Fe(III) centre bound to two tridentate mida ligands arranged in the...
