Controversial femur could belong to ancient human relative

Ancient DNA from Human and Animal

Research on ancient DNA (aDNA) has the potential to enable molecular biologists and archeologists to decipher certain aspects of history by direct looking into the past. However, several major problems in this field limit the applicability of aDNA studies, most importantly contamination with modern DNA and postmortem DNA degradation. In this study we extracted and analyzed aDNA obtained from ~3...

Human Epidermal T Cells Predominately Belong to the Lineage Expressing

Normal human epidermis, long since dismissed as merely a protective covering for the body, is now recognized as a complex immunological unit . This concept is based on the demonstration that Langerhans cells (LCs)t are potent APCs for a variety of T cell (TC) responses and that keratinocytes (KC), at least upon stimulation, can secrete a plethora of immunomodulating cytokines (reviewed in refer...

The Need to Belong

Sex determination using the femur in an ancient Japanese population.

Determination of sex from the femur measurements has been attempted in several populations and various studies have demonstrated the importance of population specific standards in the metric assessment of sex. The present study attempts to establish metric standards for sex determination by using femur measurements for ancient Japanese populations. Osteometric data were obtained from 151 adult ...

Sufficient matrices belong to L

In this paper, we establish a significant matrix class inclusion that seems to have been overlooked in the literature of the linear complementarity problem. We show that P∗, the class of sufficient matrices, is a subclass of L. In the course of demonstrating this inclusion, we introduce other new matrix classes that forge interesting new connections between known matrix classes.
