cyanogen/dental caries

Chronic beta-adrenoreceptor (beta-AR) activation increases left ventricular (LV) cavity size by promoting a rightward shift in LV diastolic pressure-volume (P-V) relations in association with increases in low-tensile strength myocardial (non-cross-linked) collagen concentrations. Because diastolic

An association of asymptomatic hyperglycemia with dietary cyanogens and socio-economic level was ascertained in 2,000 volunteers in rural communities in South-East Nigeria. The staples of the poor consisted of one or two bulky carbohydrate meals (derivatives of different species of cocoyam, cassava,

The amino acid sequence of the COOH-terminal CNBr fragment, F3 (residues 130 to 237), of concanavalin A has been established, completing the determination of the covalent structure of this lectin. Analysis of the chemical sequence showed that the distribution of charged residues is generally more

The enantiomers of a variety of N-alkyl-, N-aralkyl-, and N-cyclopropylalkyl-9β-hydroxy-5-(3-hydroxyphenyl)morphans were synthesized employing cyanogen bromide and K2CO3 to improve the original N-demethylation procedure. Their binding affinity to the μ-, δ-, and κ-opioid receptors (ORs) was

The primary structure of the muscle aldolase molecule was studied as affected by semilethal doses of valine administered the abdominal cavity of the rabbits after a long fasting. It is established that in spite of differences in the amino acid composition of the protein, uniformity of the peptides

The retinol-binding site of beta-lactoglobulin has been located by selective modification of amino acid residues which reside in the two putative binding sites. Based upon two separate crystallographic analyses of bovine beta-lactoglobulin, different binding sites for retinol have been proposed: one

Phosphoprotein appears to play an important role in the mineralization of dentin during tooth development and remineralization after demineralization by dental caries. To better understand this role, we describe the extraction and characterization of phosphoprotein from immature, human root apex

Recognition of the carbohydrate part of cellular glycoconjugates by sugar receptors like lectins may contribute to biosignaling and interactions between normal and transformed cells. Such recognitions may be essential for establishing phenotypic characteristics in neoplastic cells, including

In phagocytosis experiments the pathogenic significance of the "clumping factor" (CF) of Staphylococcus aureus was studied. CF-positive staphylococci were engulfed considerably less by leukocytes from rabbits and cattle than CF-negative staphylococci. Equally, the engulfment of staphylococcal

In refractory mosquitoes, melanotic encapsulation of Plasmodium ookinetes and oocysts is a commonly observed immune response. However, in susceptible mosquitoes, Plasmodium oocysts develop extracellularly in the body cavity without being recognized by the immune system. Like Plasmodium gallinaceum

Intergeneric bacterial adherence is responsible for the complexity of the microbiota in human dental plaque and is believed to enable some extraneous bacteria to initially colonize the human oral cavity. Some current evidence indicates that Streptococcus sanguis, an early colonizer of teeth,

Binding of Porphyromonas gingivalis to the host cells is an essential step in the pathogenesis of periodontal disease. P. gingivalis binds to and invades epithelial cells, and fimbriae are thought to be involved in this process. In our earlier studies, two major epithelial cell components of 40 and
