different examination have shown that rheumatoid factor is not responsible for false positive reaction (f.p.r.) in cr. neoformanse’s free capsular antigen latex agglutination test, whereas high levels of iron in sera of patients with rheumatoid arthritis as well as other sera was responsible not only for this f.p.r. , but also had an important role in the production of f.p.r. in many slide late...

BACKGROUND AND PURPOSE Natural rubber latex is the most important occupational allergen among medical workers, and remains a significant occupational health issue in Taiwan. We conducted this large-scale hospital-based screening study to understand the incidence of latex allergy and latex sensitization among medical workers in Taiwan over the past 5 years. METHODS 1253 medical workers were en...

There is lack of data on the prevalence of latex allergy in the health care setting in Iran. This study was performed to determine the prevalence of type I latex allergy and type IV allergy to latex and rubber additives among the operating room staff with glove-related symptoms in 13 general hospitals in Tehran. Skin-prick tests with commercial latex extract, patch tests with latex and 25 rubbe...

Latex allergy has become an epidemic among healthcare workers. Other individuals who are frequently exposed to latex gloves or products containing latex have experienced latex hypersensitivity, as well. Identification of patients who have latex allergy is crucial to physicians in order to formulate a management plan. This article includes discussion of the basic background on latex preparation,...

Consecutive extraction of latex and natural rubber from the roots of rubber-bearing plants such as Taraxacum kok-saghyz (TKS), Scorzonera tau-saghyz (STS), and Scorzonera Uzbekistanica (SU) were carried out. Latex extraction was carried via two methods: Blender method and Flow method. The results of latex extraction were compared. Cultivated rubber-bearing plants contained slightly higher latex...

Although writing documents with LATEX is straightforward, programming LATEX to automate repetitive tasks—especially those involving complex string manipulation—can be quite challenging. Many operations that a novice programmer can express easily in a general-purpose programming language cannot be expressed in LATEX by any but the most experienced LATEX users. PerlTEX attempts to bridge the worl...

This paper reported the pollutant removal performances of a hybrid wetland system for the treatment of aquaculture wastewater. The system consisted of two treatment stages: a subsurface vertical flow (VF) wetland, followed by a horizontal flow (HF). The aquaculture wastewater with the different concentrations such as eutrophy and mesotrophy was treated using hybrid constructed wetland. The expe...

In many regions of the world, urban water systems will need to transition into fundamentally different forms to address current stressors and meet impending challenges-faster innovation will need to be part of these transitions. To assess the innovation deficit in urban water organizations and to identify means for supporting innovation, we surveyed wastewater utility managers in California. Ou...

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...
