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...

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...

Background Amaranthus pollen grains are known to be highly allergenic and a potential cause of respiratory allergic diseases in many countries. Amaranthus palmeri pollen is an important allergenic source in Mexico; however in our country, there is not reported data about the prevalence of these pollens. The first allergenic profilin was identified from birch pollen allergen (Bet v 2) in 1991. M...

Latex products have long been recognized as a cause of latex protein allergy. The increased usage of latex gloves, with the consequent increased occurrence of latex allergies appears to have escalated with increasing awareness of the transmission of HIV-AIDS and other infections. The use of condoms as a means to prevent the transmission of STD's (sexually transmitted diseases) and HIV-AIDS has ...

With the recent increase and awareness of natural rubber latex protein allergies, it is very important for all health care workers to understand and recognize the need to decrease and/or eliminate latex exposure in the rubber gloves and other rubber products for those individuals who are allergic to natural rubber latex. This study is based on a series of Lowry method of protein analysis. The f...

Beginning in the 1980s, use of latex gloves to protect health care workers against exposure to blood and body fluids increased. Since then, the number of reported cases of latex sensitivity also has increased. Reactions to latex range from contact dermatitis to anaphylactic shock. Low-powder, powder-free, and non-latex gloves provide alternatives to protect health care workers from occupational...

2 The Components of LATEX The LATEX distribution at the CTAN archives is organised into the following directories. base Contains the core LATEX files. You need at least these files for a minimal LATEX installation. unpacked Includes all the files in base together with the result of ‘unpacking’ the source files. (More about this later.) Thus when obtaining LATEX you should get either base or unp...

The prevalence and severity of latex allergy has increased dramatically in the last 15 years due to exposure to natural rubber products. Although historically this health risk has been elevated in hospital personnel and patients, a recent survey has indicated a significant potential risk for the general population. To obtain a wide-spread source for latex exposure, we have considered tire debri...

OBJECTIVES To estimate the prevalence of sensitisation to natural rubber latex in latex tappers and latex glove factory workers, and to relate this to airborne exposure to latex. METHODS Five hundred workers employed in three latex glove factories, 314 tappers, and 144 college students (control group) were studied. The workers in the glove factories were classified into three exposure groups;...
