In this research, several series of triarylmethane dyes containing one or more terminal methoxy substituents with a variable tertiary amino groups have been used. These dyes have been applied to different substrates by using various methods including transfer printing and then their fastness properties were measured. These dyes shows exceptionally high light fastness (6-7) on acid modified poly...

We demonstrate that two hydroxycinnamic acids, (E )-ferulic acid and (E )-p-coumaric acid, have the ability to protect against oxidative stress and genotoxicity in cultured mammalian cells. They also show the ability to reduce the activity of the xenobiotic metabolising enzyme, cytochrome P450 1A, and downregulate the expression of the cyclooxygenase-2 enzyme. At equitoxic doses, their activiti...

1. The ionic dependence of action potentials evoked in giant smooth muscle fibres isolated by enzymatic digestion from the body wall of the marine invertebrate Beroe ovata (Ctenophora) has been investigated using conventional electrophysiological techniques. 2. Differences were observed in the two fibre types studied. The resting membrane potential was —60 ± 135 mV (JV = 25) in longitudinal mus...

Various environmental concerns motivate scientists and researchers to look out for unique new materials in science technology. In order address the demand polymeric with partial biodegradability, usage of lignocellulosic fibre polymer matrix has risen. Lignocellulosic fibres are a cheap, easily renewable resource that is readily available all regions. Cellulosic plant also have plethora possibi...

white, red and superficial. In common with teleost fish, the different types are well segregated in the body. The white fibres make up the bulk of the body, the red fibres form a band along the lateral edge of the body and the single layer of superficial fibres is confined to a narrow band between the skin and the red fibres. Each fibre type has a distinct histological and biochemical profile w...

Animal production is under fire. When considering the future of animal production, questions are being asked from all sides. Can we afford animal production? Does man really need animal protein in his diet ; would plant protein supplemented with vitamin B12 fulfil his nutritional needs ; does he really need animal fibres and hides? Is it cruel to use animals in the service of man? Perhaps we as...

The physical properties exerted by dietary fibre are individual to the age and aiiatomy of the fruit or vegetable eaten. The physical properties will be determined by the chemistry of the constituent polysaccharides and lignins, In the plant these rnacromolecules arc systematically intermeshed for anatomical and physiological function. This intimate admixture is lost during digestion but the ma...

An efficient technology for preparing lotus fibres under microwave irradiation was developed. The lotus fibres were characterized by scanning electron microscopy, Fourier transform infrared spectrometry, X-ray diffraction and thermogravimetry. Lotus fibres prepared are a kind of hollow fibres which are composed of a superfine fibre and an external shell. The effect of the treatment time with hy...

The occurrence and distribution of neuropeptide-containing nerve fibres in the human circumvallate papillae were examined by the peroxidase-antiperoxidase immunolocalisation method using surgical specimens that had not been subjected to radiotherapy, and the abundance of neuropeptide-containing fibres was expressed as the percentage of total nerve fibres demonstrated by protein gene product (PG...

The Pasteuria group of Gram positive bacteria are invertebrate parasites with the potential to be developed into biological control agents of plant-parasitic nematodes. A key step in the infection process is the attachment of endospores to the cuticle of plant-parasitic nematodes, possibly through a Velcro-like attachment system involving the collagen-like fibres of the exosporium (Davies, 2009...
