Sorbitol-bile salts broth was modified by the addition of 0.5% peptone for the enrichment of Yersinia enterocolitica in nonfood samples. A quantitative comparison was made of the growth of Y. enterocolitica in sorbitol-bile salts broth and peptone-sorbitol-bile salts broth at 22 degrees C. Incubation for 48 h resulted in an average 7.79 log10 increase in a viable cell number for six serotypes w...

Allergies to iron salts are seldom reported. We studied a patient with iron-defi ciency anemia who had suffered anaphylactic reactions caused by oral iron salts. An allergy study was performed using single-blind, placebo-controlled oral challenge and skin tests with various iron salts as well as excipients in commercial formulations. Oral challenges were positive for 2 of the commercial formula...

Proper characterization is an important aspect of any dosage form design. The objective of this work was to characterize tannate salt and hydrochloride salt of diphenhydramine. As a part of characterization studies, Differential scanning calorimetry was used to investigate thermal effects and nature of salts, supported by X-ray powder diffraction. Scanning electron microphotographs was used to ...

Cellulose derivatives are promising bio-based polymeric materials with possible applications ranging from thickening agents and stabilizers to optical films. The precise determination of their degree substitution (DS) is crucial, as the DS substantially influences material properties such cellulose derivatives. Herein, applicability attenuated total reflection-Fourier transform infrared for est...

A series of thioether-functionalised imidazolium salts have been prepared and characterized. Subsequent reaction of the thioether-functionalised imidazolium salts with iodomethane affords imidazolium-sulfonium salts composed of doubly charged cations and two different anions. Imidazolium-sulfonium salts containing a single anion type are obtained either by a solvent extraction method or by anio...

Systemic endotoxaemia is associated with postoperative renal dysfunction in obstructive jaundice, and can be prevented by the pre-operative administration of certain bile salts. In order to find the most effective bile salt for use in this condition, a comparison of the anti-endotoxic activities of different bile salts was performed. Bile salts were incubated in vitro with endotoxin and the res...

BACKGROUND Acetamidines are starting materials for synthesizing many chemical substances, such as imidazoles, pyrimidines and triazines, which are further used for biochemically active compounds as well as energetic materials. The aim of this study was to synthesise and characterise a range of acetamidinium salts in order to overcome the inconvenience connected with acetamidinium chloride, whic...

Research in plant disease management focuses on developing safe methods for humans and the environment in order to prevent the entry of harmful chemicals in food. Simple inorganic salts have low cost and are safe enough to be used as pesticides. Phytophthora genus causes crown and root rot (gummosis) in crops and leads to great losses in some pistachio (Pistacia vera L.) produ...

ETHNOPHARMACOLOGICAL RELEVANCE This article presents the results of an anthropological and ethnobotanical study of the vegetable salts used by the Witoto Indians of the Amazon. It thoroughly documents the species used, the processing of the salts, their chemical composition and their anthropological, nutritional and medicinal relevance. MATERIALS AND METHODS Salts from 57 plant species known ...

Literature data on the bioavailability of various Mg forms provide scarce information on the best Mg salt to be used in animal and human supplementation. This study aimed to investigate the bioavailability of different forms of Mg in rats using Mg stable isotopes. Eighty male Wistar rats aged 6 weeks were fed a semi-purified Mg-depleted diet for three weeks. The rats were then randomised into t...
