A comparison is made of tests for thyroglobulin antibody, using gel diffusion, electroprecipitin, bentonite flocculation, tanned red cell agglutination, and latex slide agglutination techniques on sera from cases of Hashimoto's disease and other thyroid disorders. Any increase in gamma globulin was also noted from the serum electrophoretic pattern. The gel diffusion and electroprecipitin tests ...

Latex agglutination reagents are widely used in microbial diagnosis, identification and serotyping. Streptococcus pneumoniae (the pneumococcus) is a major cause of morbidity and mortality world-wide. Current vaccines target the pneumococcal capsule, and there are over 90 capsular serotypes. Serotyping pneumococcal isolates is therefore important for assessing the impact of vaccination programs ...

In this study we use two types of methods for detecting Rota virus in 91 stool specimens from children with acute gastroenteritis. The aim of this study to determine the performance (sensitivity & specificity) of latex agglutination (LAT) and enzyme linked immunos-orbentassay (ELISA) for evaluation children acute gastroenteritis by Rotavirus. Fecal samples were collected from ninety one childre...

BACKGROUND Staphylococcus aureus is one of the most important contagious bacteria causing subclinical bovine mastitis. This bacterial infection is commonly identified by determine the pathogen in bovine milk samples through conventional technique including coagulase test. However, this test has several disadvantages as low sensitivity, risk of biohazard, cost expensive, and limited preparation ...

BACKGROUND The high prevalence of latex sensitization in patients with spina bifida (SB) has been attributed to repeated and early exposure to latex products. Other diseases such as gastroschisis/omphalocoele and post-haemorrhagic/congenital hydrocephalus are also associated with repeated and early latex exposure. OBJECTIVE The aim of the study was to evaluate whether the high prevalence of l...

A total of 138 isolates, 118 methicillin-resistant Staphylococcus aureus (MRSA) isolates (staphylococcal cassette chromosome type II, 20 isolates, type III, 39 isolates and type IV, 59 isolates) and 20 methicillin-sensitive S. aureus isolates were evaluated by phenotypic methods: cefoxitin and oxacillin disk diffusion (DD), agar dilution (AD), latex agglutination (LA), oxacillin agar screening ...

The aim of this study was to optimize the conditions for the passive adsorption of polyclonal antibody onto plain surface polystyrene latex particles and its performance in a slide latex agglutination test for rotavirus antigen detection. Cleaning of latex particles by washing through repetitive centrifuging, decanting and resuspending in distilled water was adequate in removing surfactants fro...

It has been reported that latex and extracts of different species of Ficus are cytotoxic to some human cancerous cell lines. In this study, cytotoxicity of fruit and leaf extracts as well as the latex of Ficus carica L. on HeLa cell line were evaluated. Ethanolic extracts of leaves and fruits were prepared through percolation and ethyl acetate and dichloromethane extracts were prepared by reflu...

CMOS single-photon avalanche diodes (SPADs) have broken into the mainstream by enabling adoption of imaging, timing, and security technologies in a variety applications within consumer, medical industrial domains. The continued scaling technology nodes creates many benefits but also obstacles for SPAD-based systems. Maintaining and/or improving upon high-sensitivity, low-noise, timing performan...

It is mainly the bulk properties of latex and ink oil that contribute to the observable differences in the ink setting dynamics rather than surface chemical wetting differences or changes in porous structure related to the inclusion of latex. It can be generalised that low latex solubility parameter (butadiene < styrene = acrylate < acrylonitrile) leads to greater oil interaction. Furthermore, ...
