TL;DR: New designed primer pairs with annealing positions close to the repeat units of the STR loci HUMFES, HUMTH01 and HUMTPOX were used for amplification and significantly increased the success rates when typing telogen hairs.
Abstract: A new approach to short tandem repeat (STR) typing of DNA extracted from telogen shed hairs is presented. Newly designed primer pairs with annealing positions close to the repeat units of the STR loci HUMFES, HUMTH01 and HUMTPOX were used for amplification. The typing results were compared to those obtained by the commonly used primer pairs by means of success rates. The primer pairs capable of producing very short amplicons (<106 bp with HUMFES, <86 bp with HUMTH01 and <87 bp with HUMTPOX) described in this study significantly increased the success rates when typing telogen hairs.

TL;DR: The widespread use of commercially produced multiplex kits has produced a situation in which nearly all European laboratories are using compatible systems and there is the potential for the introduction of a pan-European DNA database, however, the exchange of results between countries is hampered by the various legislations which currently exist.

TL;DR: Using UV-visible range microspectro-photometry (MSP) spectra, the degree of spectral variation and consequent discriminating power of MSP varied according to the dye class, from 0.13 for sulphur dyes to 0.93 for reactive dyes.

TL;DR: An as yet unknown large insect species capable of modifying bone with their mandibles is thus postulated in the palaeohabitat represented by the hominid-bearing Upper Laetolil Beds.
Abstract: Non-contact optical 3D-profiling instruments are often used in the study of surface modifications on fossil mammalian bone. The advantage of optical laser scanning for the study of fossil and sub-fossil bone is its non-contact nature, allowing the investigation of fragile and poorly preserved surfaces. The high resolution and fast measuring rate of this method make it an alternative to scanning electron microscopy (SEM) investigation if topography is to be visualized. This study analyses clusters of incisions in a suid humeral fragment from the Pliocene Upper Laetolil Beds. The marks show a characteristic crest structure that is also frequently found in mandible marks produced by the Australian termite species Mastotermes darwiniensis. The marks from the Laetolil Beds are, therefore, interpreted as also being caused by insect mandible action. An as yet unknown large insect species capable of modifying bone with their mandibles is thus postulated in the palaeohabitat represented by the hominid-bearing Upper Laetolil Beds.

TL;DR: Postmortem examination revealed that death resulted because of subarachnoid and intraventricular hemorrhage caused by the rupture of an intracranial aneurysm, and the close temporal correlation suggests that a sudden rise in blood pressure was cause by the electric current and was thus responsible for the rupture.
