The free amino acid profile of cocoa nibs as a result of hydrolysis by proteolytic enzyme from wastewater of latex Hevea brasiliensis processing on cocoa nibs were monitored for 8 hours. Pepsin enzyme is using as control. There are similarities profile of free amino acids produced by the enzyme from wastewater and the pepsin enzyme. If using proteolytic enzyme from wastewater, the acidic free a...

latex allergy has become an occupational hazard among healthcare workers. atopy, intensity and duration of exposure have been recognized as predisposing factors for latex sensitization. frequency of sensitization varies among countries. so we decided to investigate the prevalence of latex sensitization and potential risk factors among healthcare workers in a general hospital. in a cross section...

Background: Latex allergy is a major occupational disease with prevalence nearly 5-17% among the health care workers. Objective: To determine the prevalence of latex glove allergy and its contributing factors among operation room staff. Patients and Methods: In this study, 512 operation room staff were evaluated for latex allergy, using a complete questionnaire. Those suspected to have latex al...

Water is one of the most stable and abundant complexes on nature that can be polluted with natural and human factors. Therefore, it is necessary to ensure a timely warning for possible accumulation of polluting metal in natural waters in order to protect public health. One of the economic and rapid methods for elements removal is displacement of metals by biosorption. The purpose of this study ...
