Let （Ω, ∑） be a measurable space and mo ： E→ Xo and m1 ： E → X1 be positive vector measures with values in the Banach KSthe function spaces Xo and X1. If 0 〈 a 〈 1, we define a X01-ax1a new vector measure [m0, m]a with values in the Calderdn lattice interpolation space and we analyze the space of integrable functions with respect to measure [m0, m1]a in order to prove suitable extensions of the classical Stein Weiss formulas that hold for the complex interpolation of LP-spaces. Since each p-convex order continuous Kothe function space with weak order unit can be represented as a space of p-integrable functions with respect to a vector measure, we provide in this way a technique to obtain representations of the corresponding complex interpolation spaces. As applications, we provide a Riesz-Thorin theorem for spaces of p-integrable functions with respect to vector measures and a formula for representing the interpolation of the injective tensor product of such spaces.

Epidemiologic studies often consider gender differences in a particular pathology, and constantly observe variations between men and wom- en. Indeed, a remarkable sexual dimorphism exists in the epidemiology of neurological conditions and brain diseases. Physiologically, males and females differ by their levels of circulating hormones that drive sexual behavioral, as well as endocrine functions. Estrogen is the pri- mary female sex hormonal group that enwraps estradiol, estrone and estriol, and which are the major naturally occurring hormones preva- lent in women. Their role in the reproductive function has long been established, although the ubiquitous expression of its receptors （alpha, beta and G protein-coupled, GPR30） presumes a broader spectrum of action. This short review will summarize the current knowledge in estrogen therapy with particular focus on some of the recent work that might lead to new neuroprotective treatments.
