X-ray diffraction is one of the powerful tools in study a variety structures stratum corneum at molecular level. Resolving structural modifications during functioning an important subject for clarifying mechanism operating principles function. Here, experimental techniques used on are widely and deeply reviewed from perspective fundamental to application. Three typical topics obtained experimen...

The recent revival of the study organic natural products as renewable sources medicinal drugs, cosmetics, dyes, and materials motivated creation general purpose structural databases. Dereplication, efficient identification already reported compounds, relies on grouping structural, taxonomic spectroscopic databases that focus a particular taxon (species, genus, family, order, etc.). A set freely...

Seaweeds due to their immense applications in food, agriculture, cosmetics, textile, biomedical and pharmaceutical sector have become inordinate candidates for research. Over the past few decades, research has been focused on algae-driven metabolites such as carrageenan, galactan, laminarin, fucoidan, lectins, phenols alginate diverse applications. Marine algae are constantly being researched a...

an ion chromatography (ic) method for simultaneous determination of benzoic, salicylic and sorbic acids was developed. in this method the samples were purified by solid-phase extraction. the analytes were then eluted with methanol from c18 cartridge. the separation was performed on ion-exclusion column by an isocratic elution with 0.25 mmol /l sulfuric acid solution containing 20% (v/v) acetone...

background: due to the presence of radioactive minerals such as monazite, the beach sand of the west coast of kanyakumari exhibits high natural background radiation. hair is a good indicator of radionuclides in the human body. an attempt is taken to measure the 210po activity in human hair samples and the factors affecting it. material and methods: 210po activity was analysed in 47 individuals ...

The growth of the cosmetic industry, together with the dramatic increase in advances in cosmetic chemistry, has been one of increasing interface with dermatologists. The change especially in dermatology has found less emphasis on medical dermatology and growth in the areas of cosmetic dermatology and dermatologic surgery. With this, the dermatologist has had to become more aware of principles a...

Tyrosinase is the key and rate-limiting enzyme responsible for the conversion of tyrosine into melanin. Competitive inhibition of tyrosinase enzymatic activity results in decreased or absent melanin synthesis by melanocytes in human skin. DeoxyArbutin (4-[(tetrahydro-2H-pyran-2-yl)oxy]phenol), a novel skin whitening agent, was synthesized through the removal of hydroxyl groups from the glucose ...

Essential oils are currently of great importance to pharmaceutical companies, cosmetics producers and manufacturers of veterinary products. They are found in perfumes, creams, bath products, and household cleaning substances, and are used for flavouring food and drinks. It is well known that some of them act on the respiratory apparatus. The increasing interest in optical imaging techniques and...

The types of pharmaceutical products include cosmetics and drugs. Some the comprise a mix drugs herbs without considering their interaction effects. Drug-herb interactions (DHIs) refer to between conventional herb medicines. However, available information on DHIs are scattered because it has heterogeneous databases website resources, apart from some paid or subscribed databases. Easy access wou...
