[Arrow poisons--relics of former times?].

Beetle and plant arrow poisons of the Ju|’hoan and Hai||om San peoples of Namibia (Insecta, Coleoptera, Chrysomelidae; Plantae, Anacardiaceae, Apocynaceae, Burseraceae)

The use of archery to hunt appears relatively late in human history. It is poorly understood but the application of poisons to arrows to increase lethality must have occurred shortly after developing bow hunting methods; these early multi-stage transitions represent cognitive shifts in human evolution. This paper is a synthesis of widely-scattered literature in anthropology, entomology, and che...

The Luminosity Function of Cluster Radio Relics

In this paper we compute the luminosity function of radio relics. In our calculation we include only those relics that are produced by the compression of former radio cocoons. This compression is provided by shocks that are generated in the process of structure formation. Starting from an analytical model for the luminosity evolution of ageing radio cocoons, the luminosity function of radio gal...

Recent developments in the field of arrow and dart poisons.

Arrow and dart poisons, considered as conventional natural sources for future drug discovery, have already provided numerous biologically active molecules used as drugs in therapeutic applications or in pharmacological research. Plants containing alkaloids or cardiotonic glycosides have generally been the main ingredients responsible for the efficacy of these poisons, although some animals, suc...

A review of Novichok Toxicology

Introduction: Novichoks are considered as the fourth generation of chemical weapons and nerve agents (NA) category. NAs were produced and developed during the Cold War in the (former) Soviet :union:. Due to the confidentiality of the manufacturing process of these agents, there is little information about the properties of these compounds. Like other NA, novichoks are organophosphorus compounds...
