A step change towards risk assessment in the 21st century.

Chemical Regulation and the means by which data is generated for the purposes of risk assessment is undergoing a tremendous shift. There is a strong impetus in Europe, in particular, to move towards non-animal approaches to address data gaps for specific endpoints either in lieu of testing or as part of weight of evidence approaches within integrated testing strategies (ITS). An Exposure assess...

Many of us have insufficient information to understand the nature and extent of the inequalities that exist, and whether our services are effective. This lack of information restricts our ability to plan appropriate st...

Another step towards celiac screening.

In 1888, Samuel Gee described a disorder of chronic maldigestion and malabsorption that affected individuals of all ages, particularly children 1 to 5 years of age, that he termed, “coeliac affection.” Although he did not know the exact cause, he aptly suspected that the treatment was some form of dietary restriction, with a reduced allowance of “farinaceous foods,” rich in starch or flour.

A Step Towards Yuzvinsky's Conjecture

An intercalate matrix M of type [r, s, n] is an r × s matrix with entries in {1, 2, . . . , n} such that all entries in each row are distinct, all entries in each column are distinct, and all 2 × 2 submatrices of M have either 2 or 4 distinct entries. Yuzvinsky’s Conjecture on intercalate matrices claims that the smallest n for which there is an intercalate matrix of type [r, s, n] is the Hopf-...
