The latex of Calotropis gigantea is a rich source of useful components that has medicinal properties and one of the main applications is in controlling the heart muscle. The crude latex extract contained many proteins, which are highly basic in nature and exhibited strong dilatation activity. Blood vessel experiment of the latex from Calotropis gigantea was studied in the green frog (Rana hexad...

BACKGROUND Natural rubber latex allergy is a "new" illness whose prevalence has reached epidemic proportions in highly exposed populations such as health care professionals. OBJECTIVE The aim of the study was to evaluate the frequency of reactions to latex and risk factors due to glove use in health care workers (HCW) in Florianopolis, Santa Catarina, Brazil. METHODS We evaluated latex-rela...

OBJECTIVES The use of latex gloves has increased by several folds in the recent past due to concerns about blood-borne infections. Data from Asian countries with regard to latex allergy is scarce. The objective of this study was to determine the prevalence and risk factors of latex allergy among healthcare workers in a tertiary hospital in Sri Lanka. MATERIAL AND METHODS A cross-sectional sur...

BACKGROUND AND OBJECTIVES The number of patients allergic to latex has increased significantly. It is crucial to recognize the cases in order to prevent and apply adequate treatment. The objective of this study was to evaluate the prevalence of allergy to latex in meningomyelocele patients. MATERIALS AND METHODS A retrospective evaluation of medical records of patients with meningomyelocele d...

Coating colors are applied to the base paper in order to maximize the performance of the end product. Coating colors are complex colloidal systems, mainly consisting of water, binders, and pigments. To understand the behavior of colloidal suspensions, an understanding of the interactions between its components is essential. A colloidal particle exerts so-called Brownian motion due to thermal co...

The most common agents that are responsible for intraoperative anaphylaxis are muscle relaxants. However, latex accounts for a significant number of these reactions, and the incidence of intraoperative anaphylaxis caused by latex is increasing. It is now probably the second most important cause of intraoperative anaphylaxis. Following muscle relaxants and latex are probably antibiotics and anes...

INTRODUCTION Guayule (Parthenium argentatum Gray, Asteraceae) is a woody desert shrub (Whitworth and Whitehead 1991) which is under commercial development as a domestic source of hypoallergenic natural rubber (Siler and Cornish 1994; Carey et al. 1995; Cornish 1996, 1998; Cornish et al. 1996, 2001; Schloman et al. 1996; Siler et al. 1996; Cornish and Lytle 1999). To expedite commercialization, ...

The performance of a commercial microplate latex agglutination assay, the Verotox-F assay, was compared with that of the Vero cell assay for the detection and characterization of Escherichia coli verocytotoxins (VTs). Culture filtrates of 68 VT-positive E. coli strains (65 human isolates [33 of serotype O157:H7/H-, 32 of non-O157 serotypes] and 3 reference strains) and 104 VT-negative strains (...

AIMS To examine A, C, Y, and W135 Neisseria meningitidis serogroup characterisation by ultrasonic standing wave enhanced latex agglutination tests (USELATs) of clinical samples. In addition, to determine USELAT enhancement of detection sensitivity for the individual antigens compared with conventional card latex agglutination tests (LATs). METHODS Wellcogen (Abbott Murex), Slidex meningite ki...

We aimed to investigate whether 1-deoxynojirimycin (DNJ) modulates glycometabolism and has toxicity in Eri silkworm (Samia cynthia ricini, Saturniidae). In this paper, hemolymph metabolites were used to explore metabolic changes after oral administration of DNJ or mulberry latex and to characterize the biological function of DNJ at the metabolic and systemic levels. Hemolymph samples were colle...
