Tumor recurrence after the incomplete removal of a tumor mass inside brain tissue is the main reason that scientists are working to identify new strategies in brain oncologic therapy. In particular, in the treatment of the most malignant astrocytic tumor glioblastoma, the use of magnetic
Synthesis of functionalized magnetic nanoparticles (NPs) for biomedical applications represents a current challenge. In this paper we present the synthesis and characterization of water-dispersible sugar-coated iron oxide NPs specifically designed as magnetic fluid hyperthermia heat mediators and
As shown in this study, the formation of antibodies, at least, to the determinants (DT) of polysaccharide of group A streptococcus (A-PS), common with epidermal antigens, occurs in rheumatic fever. Two DT include N-acetylglucosamine; DT common with epidermal basal cell antigen (DT-1) and DT common
Bacterial mucopeptide is an integral part of bacterial cell walls and is therefore ubiquitous in our environment. An enhanced degree of humoral immunity has ben detected not only in patients with acute rheumatic fever (ARF), with a known recent response to streptococci, but also in patients with
Salmonella paratyphi A is increasingly recognized as a common cause of enteric fever cases and there are no licensed vaccines against this infection. Antibodies directed against the O-polysaccharide of the lipopolysaccharide of Salmonella are protective and conjugation of the O-polysaccharide to a
Salmonella paratyphi A, the second most common cause of enteric fever in Southeast Asia, is a habitant of and a pathogen for humans only. Lipopolysaccharides (LPS) are both essential virulence factors and protective antigens for systemic infections caused by groups A, B, C, and D nontyphoidal
Direct dependence was established between the presence of autoantibodies reacting with the basal layer of the skin epithelium (BLSE) and the high level of antibodies to the streptococcal group A polysaccharide (APS). By the primary active rheumatic fever (PARF) autoantibodies to the BLSE are
Lipopolysaccharide extracted with phenol-water from Leptospira interrogans serovar copenhageni strain Shibaura (L-LPS) showed various biological activities. In lethality for mice, L-LPS was active (LD 50, 3.4 mg/mouse) but about 12 times less potent than Escherichia coli LPS (E-LPS) per weight
Glinus oppositifolius (L.) Aug. DC. (Aizoaceae) is a Malian medicinal plant used against various types of illnesses related to the immune response, like joint pains, inflammations, fever, malaria and wounds. Two pectin type polysaccharides, GOA1 and GOA2, being isolated from a 50 degrees C water
Lipopolysaccharide (LPS) from Haemophilus pleuropneumoniae 1536, serotype 2, was isolated and purified by a procedure designed to be equally satisfactory for both smooth- and rough-type LPS. The LPS yield was 53%. Analysis of the preparations revealed that protein, nucleic acid, and cellular
BACKGROUND
Elephantorrhiza elephantina (Ee) and Pentanisia prunelloides (Pp) are two medicinal plants which are widely used to remedy various ailments including diarrhoea, dysentery, inflammation, fever, rheumatism, heartburn, tuberculosis, haemorrhoids, skin diseases, perforated peptic ulcers and
Operculina turpethum (Linn.) (OT) Silva Manso belongs to the family Convolvulaceae. This review incorporates literature for the phytochemical and pharmacological profile of OT herb. Exhaustive literature survey was done using all the details on phytochemistry and pharmacology of OT available. This
Infective endocarditis is characterized by the formation of septic masses of platelets on the surfaces of heart valves and is most commonly caused by viridans streptococci. Streptococcal virulence in endocarditis involves factors that promote infectivity and pathogenicity. Adhesins and
Tetrastigma hemsleyanum Diels et Gilg (Sanyeqing) is traditionally used as a folk medicine for the treatments of inflammation, high fever, hepatitis and cancer, and can improve the immune function of the patient. It belongs to the family of Vitaceae, and is mainly distributed in Salmonella enterica serovar Typhi (S. Typhi) is a foodborne pathogen that causes typhoid fever and infects only humans. The ability of S. Typhi to survive outside the human host remains unclear, particularly in human carrier strains. In this study, we have investigated the catabolic activity of a
