Triple-base changes were made in each of the five Integrase (Int) arm-type binding sites of bacteriophage lambda. These triple changes, called ten mutants, were compared with single-base changes (hen mutants) for their effects on integrative and excisive recombination. The presence of ten or hen mutations in the P1, P'2, or P'3 sites inhibited integration, but the ten P'3 mutant was 10-fold mor...

Genetic factors that regulate the pathogenesis of pneumonia caused by the fungus Cryptococcus neoformans are poorly understood. Through a phenotypic strain survey we observed that inbred C3H/HeN mice develop a significantly greater lung fungal burden than mice of the resistant CBA/J strain 4 weeks following intratracheal infection with C. neoformans ATCC 24067. The aim of the present study was ...

BACKGROUND AND OBJECTIVES We aimed to characterize the effect of home enteral nutrition (HEN) on the nutritional status and the quality of life (QOL) of esophageal cancer patients who underwent Ivor Lewis esophagectomy for cancer. METHODS AND STUDY DESIGN Sixty patients with esophageal cancer were assigned to receive either HEN (n=30) or standard care only (n=30) from 1 week to 24 weeks follo...

The egg production sector is in a transitional period with regard to the permitted housing systems, i.e. rearing conventional cages under certain conditions complete ban of any form cage system. changes were caused by concern for layer wellfare but expected effects on productivity as well. aim research was determine floor space allowance and non-cage systems feather score laying hens three ages...

We discuss a model of dark matter consisting high energy anti-electron-neutrinos with leptonic force, which is produced by the conserved charge gℓ associated Lee–Yang’s U1 gauge symmetry. Based on particle-cosmology for early universe, neutrino (HEN) assumes that neutron decay processes, n→p++e−+ν¯e, dominate epoch after creation, collision and confinement processes quarks antiquarks in beginni...

Total RNA from hen oviduct has been hydrolysed with a mixture of T(1) and pancreatic ribonucleases. Poly(A) tracts in the digestion product have been isolated by binding to oligo(dT) cellulose. Of the four major ribonucleotides, the product has been shown to contain only adenylic acid. When separated on polyacrylamide gels, the poly(A) gave two peaks corresponding to average apparent lengths of...

An experiment was conducted to study the effect of Epinephrine (EP) and bromocriptine (BR) on productive traits of laying hens. Thirty White Leghorn hens, 50 weeks old, were divided into three equal treatments (with 10 hens for each treatment): control, physiological serum (0.5 mL/hen/week), EP (0.5 mL/hen/week) and BR (100 g/kg of body weight (BW); w/v in absolute alcohol). Hens were injected ...

Hen egg white lysozyme, fully inactivated by the affinitylabeling reagent, the 2’,3’-epoxypropyl fl-glycoside of di-(NaCetyl-D-glUCOSamine), contained 1 mole of the label per mole of protein. Total enzymatic digestion of the reduced and carboxymethylated affinity-labeled enzyme afforded, as a major radioactive product, a compound composed solely of aspartic acid and glucosamine at the molar rat...

The difference in susceptibility to urinary tract infection between C3H/HeJ and C3H/HeN mice was tested for with gram-negative strains differing in lipopolysaccharide composition. Recently, impaired clearance of Escherichia coli from the kidney of C3H/HeJ compared to C3H/HeN mice was shown to be correlated with the LPS low responsiveness. In this study, a difference in clearance from the kidney...
