use of natural antimicrobial compounds extracted from plants such as cinnamon as preservative to extend the shelf life has gain much attention. in this study, we evaluated the antimicrobial activity and bio- preservative potential of the methanolic extract of cinnamomum verum bark and its oil against bacillus subtilis , pseudomonas aeruginosae and escherichia coli in ketchup sauce. in order to ...

This study's interest relies on adolescents' social representations of unprotected sex, more precisely on the relationship between the attitude towards the preservative and the reason attribution for its non use. 1386 secondary school students took part in the study, in the Brazilian cities of Florianópolis, Itajaí and Balneário Camboriú. In order to verify reasons attributed by the students, w...

Post-acidification of set yoghurt always occurs during cold storage causing short shelf life thus consumer unacceptability. The short storage life of particular yoghurt affects the consumption level as well. This study concentrated on the inhibitory effect of preservatives on post-acidification of yoghurt. The set yogurt mixture was produced and inoculated with 2% starter culture containing Str...

This study compared the efficacy of a common medication diluent, bacteriostatic 0.9% sodium chloride containing the preservative benzyl alcohol with lidocaine hydrochloride 1% as an intradermal pretreatment for the relief of pain associated with intravenous cannulation. Forty adult presurgical patients requiring two large bore intravenous catheters were used. They served as their own controls. ...

Vaccines remain one of the most effective ways to prevent infectious disease and deaths globally. Universal childhood immunization provides herd immunity against many infectious agents and is a policy that has achieved dramatic reductions in common childhood illnesses. Thimerosal, which contains ethyl mercury, has been used as a preservative in vaccines to prevent contamination of multidose via...

Ocular Surface Disease (OSD) is prevalent among medically treated patients with glaucoma. This is basically related to three key-points: OSD and glaucoma are both prevalent in elderly and are common comorbidities in the same patient; the role of the active ingredient of the medical antiglaucomatous therapy; the role of the preservative agent of this medical therapy. Considering the actual state...

Escherichia coli O157:H7 is a member of the enterohemorrhagic group of pathogenic E. coli that has emerged as a foodborne pathogen of major public health concern. E. coli O157:H7 is highly tolerant of acidic pH and outbreaks attributed to this bacterium have been in many acidic foods which have pH level with similar to those of pickled products. Therefore, pickled vegetables, although acidic, m...

Soil samples were collected from field sites in two AWPA (American Wood Protection Association) wood decay hazard zones in North America. Two field plots at each site were exposed to differing preservative chemistries via in-ground installations of treated wood stakes for approximately 50 years. The purpose of this study is to characterize soil fungal species and to determine if long term expos...

A rationally based procedure has long been needed for assigning design adjustments to Southern Pine lumber treated with waterborne preservative. This paper attempts to develop such a procedure by evaluating a series of models to predict the short-term effects of waterborne preservative treatments on the strength of U.S. Southern Pine lumber. Input data consisted of non-parametric treated to unt...

The paradoxical bronchoconstriction observed with commercially available isotonic ipratropium bromide nebuliser solution (Atrovent) in patients with asthma results from an adverse reaction to the preservatives, benzalkonium chloride and ethylenediaminetetra-acetic acid (EDTA). The airway response to inhaled Atrovent and preservative free ipratropium bromide nebuliser solutions has been examined...
