Themed issue: Cosmetic Ingredients

14 Mar 2012

Analytical themed issue on cosmetic ingredients We’re delighted to announce that submissions are open for a new themed issue Guest Edited by Professor Alberto Chisvert and Professor Amparo Salvador of the University of Valencia, Spain.

Cosmetic Ingredients: from the cosmetic to the human body and the environment

The aim and scope of this themed issue is to compile articles focused on useful analytical methods to determine cosmetic ingredients not only in cosmetic products but also in biological and environmental samples.

Nobody can doubt the increasing demand for cosmetic products. They may not have as many health implications as pharmaceutical products or food, but are chemical products that are used daily on skin, hair, nails and teeth.

Using blood, not urine, to diagnose kidney stones

02 Feb 2012

A method to diagnose urinary lithiasis at an early stage has been devised by Wei Hang and colleagues in Xiamen, China. The method can also distinguish between the different types of stone, which is important when considering treatment options.

Currently, distinguishing between types can only be done after the stones have been removed from a patient, making it difficult to prescribe a treatment.

Urinary lithiasis, stones in the lower urinary tract, has become more common, with about 100,000 new cases each year. It causes substantial pain and leads to renal failure. The stones are caused by a build up of organic materials and inorganic crystals.

The team’s diagnostic method uses elemental analysis on blood serum samples to detect the levels of barium, gallium, antimony and sodium; variations from the norm are linked to the appearance of stones. The test subjects could then be subdivided into calcareous and non-calcareous stone patients by metallomic profiling, and the team found that selenium levels play a major role in this classification.

Diagnosis of kidney stones by elemental analysis of blood samples

Gao et al., Anal. Methods, 2012

Compared with urine samples, blood serum samples show smaller variability under normal physiological conditions so are a better choice for elemental screening, say the researchers.

New avenues for platelet study: unlocking the P2X1 receptor

01 Feb 2012

Anderson et al., Anal. Methods, 2012, 4, 101-105

Dana Spence and colleagues at Michigan State University have developed a way to study the P2X1 receptor on platelets, providing new possibilities for the research of these important cells.

The primary function of platelets in the bloodstream involves maintaining hemostasis and preventing blood loss through the clotting process.

Platelets are found in the bloodstream and function to maintain hemostasis and prevent blood loss via clotting. Adenine receptors on the surface of the platelet are important in this process, most notably the ADP-sensitive receptors P2Y1/P2Y12, and the ATP-sensitive P2X1 receptor.

Roles for P2Y-type receptors in platelet activation are well established, but the role of the P2X1 receptor is less clear as it has proven difficult to study. P2X1 is rapidly desensitised during in vitro experiments, particularly when the platelets have been separated from plasma and washed.

Professor Dana Spence, Michigan State University, USA

Here, Professor Spence – who is on the Advisory Board of Analytical Methods‘ sister journal, Analyst – and his team use the reported P2X1 inhibitor NF449 to sensitise washed platelets, enabling them to be properly studied.

In a press release from MSU, Professor Spence says, “This receptor, P2X1, has long been viewed as not important in platelets; our studies show that is not necessarily true. The receptor is very active; you just need to be careful in working with it.”

He hopes that this now opens up investigation of the P2X1 receptor as a potential drug target for the treatment of conditions such as diabetes and hypertension.
