Breast milk is a complex fluid, rich in nutrients and non-nutritional bioactive components, including antimicrobial factors, immunoglobulins, cytokines, and anti-inflammatory substances. Although IgE is implicated in viral immunity, its role in breast milk in parvovirus B19 immunity has not been studied. Total immunoglobulin levels of IgE, IgG, and IgE anti-parvovirus B19 antibodies were determ...

Human milk was collected from women in their 10th-14th weeks of lactation, and was analysed for amino acids. Corrections were made for losses of amino acids which were presumed to occur during acid hydrolysis, using a non-linear mathematical model that describes the simultaneous processes of amino acid yield and decay. The mean amino acid composition of the human milk was found to be similar to...

BACKGROUND Accurately targeting the nutritional needs of the early preterm infant is challenging when human milk is used due to the natural variation in energy composition. The purpose of this study was to develop and evaluate a simple method for reducing the variation in fat and energy content of human milk prior to fortification such that the infant receives a diet of known composition. MET...

The electrochemiluminescence (ECL) of Ru(bpy)(3)(2+) at bare and single-wall carbon nanotube (SWNT) modified glassy carbon (GC) electrodes has been employed for the determination of melamine for the first time, giving a linear response (R(2) = 0.99682) for melamine concentration from 1.0 × 10(-10) to 1.0 × 10(-5) M at a bare GC electrode in pH 10 borate buffer, and the detection limit is 1.0 × ...

A high-performance liquid chromatography method is described in this paper. The method uses NH(2) column and 97% acetonitrile eluate to determine the insecticide cyromazine and metabolite melamine residues in milk and pork. Samples were treated with NaOH and extracted with acetonitrile containing 20% NH(4)OH. Target analytes of samples were cleaned up and concentrated by C(18) column solid-phas...

Infant Milk Formula (IMF) is designed as a breastmilk substitute to satisfy the nutritional requirements during first months of life. This study investigates effects two IMF processing technologies on cow milk protein digestion using an infant static in vitro gastrointestinal model. The degree hydrolysis at end gastric phase was 3.7-fold higher for produced by high temperature (IMF-HT), compare...

OBJECTIVES To identify the fluoride content of powdered formula for infants 0-12 months in products available from Brisbane stores in 2006/07 and compare this with the fluoride content of infant formula products available in Australia 10 years earlier. METHODS A range of available infant formula powders were collected from major supermarkets and chemists in Brisbane, Queensland. The fluoride ...

AIM Benefits of human breast milk (HM) in avoiding rapid infancy weight gain and later obesity could relate to its nutrient content. We tested the hypothesis that differential HM total calorie content (TCC) or macronutrient contents may be associated with infancy growth. METHODS HM hindmilk samples were collected at ages 4-8 weeks from 614 mothers participating in a representative birth cohor...

Ambient ionization using a low-temperature plasma (LTP) probe combined with tandem mass spectrometry (MS/MS) allows detection and quantitation of melamine in milk powder, whole milk and other products at levels down to low ppb in analysis times of a few tens of seconds.

This study aimed to investigate the survival of Vibrio cholerae O1 in 3 types of preparation for cooked rice, Oryza sativa L., (plain rice, rice with coconut milk, and rice with ginger); coffee, Coffea canephora, (plain coffee, coffee with sugar, and coffee with sweetened condensed milk); and tea, Camellia sinensis, (plain tea, tea with sugar, and tea with sweetened condensed milk) held at room...
