The purpose of the study was to evaluate the safety and efficacy of a galactose epimeraseless mutant of Salmonella typhimurium administered as an oral vaccine to one week old calves and to investigate properties of galactose epimeraseless mutants which affect their virulence and immunogenicity. The
The addition of D-glucose, D-galactose, or D-mannose to culture medium increased survival of heated Chinese hamster ovary cells in a concentration- and time-dependent manner. Heat protection by sugars was not immediate but required prior incubation in the sugar medium before hyperthermia. The degree
Using rabbit erythrocyte-derived neutral glycosphingolipids enriched for a ceramide pentasaccharide as the antigen, we detected elevated anti-galactosyl-alpha(1-3)galactose (anti-G alpha G) antibody levels in 76% of children with active visceral leishmaniasis (kala-azar [KA]) and in 42% of
A recombinant plasmid pMM-CTB containing the gene for production of the nontoxic B subunit of Vibrio cholera was transferred into a safe, effective and attenuated oral vaccine Ty21a strain of Salmonella typhi. The resulting Ty21a (pMM-CTB) could steadily produce CT-B subunit that was secreted
A total of 124 children aged 0.2 to 6 years were enrolled in a study of first time febrile urinary tract infection. The patient population was stratified in groups according to the stringency of criteria for fever and bacteriuria and the presence of concomitant disease. The major group of 88
We used the Salmonella typhi galactose epimerase (galE) mutant strain Ty21a, shown to be a safe, effective, living, attenuated oral typhoid vaccine, as a recipient for a recombinant plasmid containing the gene for production of the nontoxic B subunit of the heat-labile enterotoxin of Escherichia
Polyclonal xenogenic IgGs, although having been used in the prevention and cure of severe infectious diseases, are highly immunogenic, which may restrict their usage in new applications such as Ebola hemorrhagic fever. IgG glycans display powerful xenogeneic antigens in humans, for example α1-3
The effect of thermotolerance and of polyhydroxy compounds on the cytotoxicity of bleomycin and cis-platinum was studied in cultured RIF tumor cells. Cell survival in response to drug-heat treatments was compared in cells not previously exposed to hyperthermia and in preheated cells that had
Extracellular African swine fever (ASF) virus particles were specifically agglutinated by several lectins, suggesting the presence of surface glycosylated component(s) containing at least glucose, mannose, or both; galactose, N-acetylgalactosamine, or both; N-acetylneuraminic acid and
Six proteins, previously established as major constituents of intact organisms, were identified in cell envelopes obtained from intrinsically radiolabeled Rickettsia prowazekii. Extrinsic radioiodination of intact organisms conducted at 0.5 micronM iodide indicated that protein 4 was the most
Laser Doppler flowmetry has been applied to subepidermal rat tumours during localized ultrasound hyperthermia and/or moderate, short-term hyperglycaemia. Blood glucose levels were elevated 4-fold by continuous i.v. infusion of D-glucose (4.8 g/kg/60 min). To determine whether the effects of
The effect of galactose on systemic hemodynamics and blood flow rate of Walker 256 carcinomas and several normal tissues of unanesthetized, unrestrained female Sprague-Dawley rats was measured, using the radioactive microsphere technique, prior to and at 30 and 60 min after galactose administration
Two galactomannans, one extracted from seeds of Mimosa scabrella, having a mannose to galactose ratio of 1.1, and another with a 1.4 ratio from seeds of Leucaena leucocephala, were sulfated. The products from M. scabrella (BRS) and L. leucocephala (LLS) had a degree of sulfation of 0.62 and 0.50,
Aim: Congenital glucose-galactose malabsorption (CGGM) is a rare disease characterised by severe diarrhoea, dehydration and weight loss. To better understand CGGM, we investigated all the case reports and series of CGGM from 2001 to
A Salmonella typhi gal E mutant, designated Ty 21a, has been developed on the basis of virulence and protection studies with similar Salmonella typhimurium mutants in mice. Gal E mutants are characterized by a block in the enzyme UDP-4-galactose-epimerase. They owe their outstanding immunizing
