Podocarpaceae and Cupressaceae: A tale of two conifers and ancient adhesives production in South Africa.

Research on ancient adhesives from the South African Stone Age is expanding, driven by excellent preservation conditions of adhesives and the potential to address diverse archaeological questions. These adhesives are primarily characterized through microscopic and chemical analysis. Despite geographic variability, a consistently identified component is Podocarpus resin or tar.

The Association Between Multidimensional Frailty and Poor Venous Accesses in a Geriatric Population: A Retrospective Study.

Since the association between frailty and difficulty in finding venous access (VA) is largely unexplored and unclear in geriatrics, the aim of this study is to demonstrate how multidimensional frailty is associated with bad VA in a population of older hospitalized people. Multidimensional Prognostic Index (MPI), based on eight different domains usually assessed in comprehensive geriatric assessment, was used for identifying multidimensional frailty; VA heritage was investigated using a questionnaire prepared by a trained nurse, based on clinical experience. Overall, 145 patients were included (mean age 78.

The dynamic lives of osseous points from Late Palaeolithic/Early Mesolithic Doggerland: A detailed functional study of barbed and unbarbed points from the Dutch North Sea.

Osseous barbed and unbarbed points are commonly recovered from the Dutch North Sea and other Mesolithic sites of northern Europe. Interpreted as elements of projectile weaponry, barbed points are considered by archaeologists to be a technological innovation in the hunting equipment of hunter-gatherers. However, debate about their exact use and identification of the targeted prey species is still ongoing.
