This report describes a new procedure for serum amylase assay. A novel substrate, dyed amylopectin, is used that combines the advantages of saccharogenic and amyloclastic methods. Serum amylase hydrolyzes the dyed amylopectin into ethanol-soluble fragments, which are quantified colorimetrically after serum proteins and unhydrolyzed substrate are precipitated with alcoholic tannic acid. The subs...

Natural dyes gained increasing attention due to environmental considerations. Many of the dye plants have also medicinal values. This study aimed to evaluate the effect of 25 plants as dyes and their dyed wool yarns against microorganisms. Prokaryotes were found to be more sensitive to dye extracts than eukaryotic microorganisms and dyestuff from Punica granatum, Berberis vulgaris, Agrimoni...

Skin exposure to permanent hair dye compounds was assessed in 33 hairdressers using a previously evaluated hand rinse method. Hand rinse samples were collected from each hand before the start of hair dyeing, after application of the dye and after cutting the newly-dyed hair. Sixteen of the hairdressers did not use gloves during dye application, and none used gloves while cutting the dyed hair. ...

the structure and histogenesis of the stigma of datura stramonium was investigated by light and scanning electron microscopy to determine the developmental origin of the transmitting tissue and “wet stigma”. four developmental stages were defined on the basis of bud length. stage one, the histogenesis stage, was comprised of buds 2-15 mm in length. stage two, signified by the growth and develop...

BACKGROUND The ultraviolet properties of textiles dyed with synthetic dyes have been widely reported in literature. However, no study has investigated the ultraviolet properties of natural fabrics dyed with natural colorants. This study reports the Ultraviolet Protection Factor (UPF) of cotton fabrics dyed with colorants of plant and insect origins. METHODS Three cotton fabrics were dyed with...

A number of polycarboxylic acids butane tetracarboxylic acid BTCA, polyacrylic-co-maleic acid PAMA, citric acid, maleic-itaconic MA-IA were examined, in combination with sodium hypophosphite SHP in order to give a similar high fabric crease recovery performance and whiteness index to traditional formaldehyde based crease agents. BTCA showed to be the best crease resist agent for crosslinking co...

background: empowerment of people with diabetes means integrating diabetes with identity. however, others’ stigmatization can influence it. although diabetes is so prevalent among iranians, there is little knowledge about diabetes‑related stigma in iran. the present study explored diabetes‑related stigma in people living with type 1 diabetes in isfahan. materials and methods: a conventional con...
