Microbial communities in soils may change in accordance with distance, season, climate, soil texture and other environmental parameters. Microbial diversity patterns have been extensively surveyed in temperate regions, but few such studies attempted to address them with respect to spatial and temporal scales and their correlations to environmental factors,(More)
Determining whether the source tissue of biological material is semen is important in confirming sexual assaults, which account for a considerable percentage of crime cases. The gold standard for confirming the presence of semen is microscopic identification of sperm cells, however, this method is labor intensive and operator-dependent. Protein-based(More)
The effect of N6-benzyladenine (BA) on the recovery of cryopreserved shoot tips of the LN33 hybrid (Vitis L.) and Troyer citrange [Poncirus trifoliata (L.) Raf. x Citrus sinensis [L.] Osbeck.] cultured in vitro was examined. For the LN33 hybrid, the presence of BA in the recovery medium was essential for survival of control and cryopreserved shoot tips,(More)
The mountain gazelle (Gazella gazelle), Dorcas gazelle (Gazella Dorcas) and acacia gazelle (Gazella arabica acacia) were historically abundant in the southern Levant, and more specifically in Israel. Anthropogenic and natural changes have caused a rapid decline in gazelle populations, raising concerns about their conservation status and future survival. The(More)
The ubiquity and transferability of soil makes it a resource for the forensic investigator, as it can provide a link between agents and scenes. However, the information contained in soils, such as chemical compounds, physical particles or biological entities, is seldom used in forensic investigations; due mainly to the associated costs, lack of available(More)
A sexual assault case resulted in a pregnancy, which was subsequently aborted. The alleged father of the fetus was unknown. Maternal and fetal types were obtained using the 11-locus AmpFℓSTR(®) SGM Plus(®) kit. The national DNA database was searched for the paternal obligatory alleles and detected two suspects who could not be excluded as father of the(More)
In 2012 the Israel Police DNA Casework laboratory adopted the 16 STR PowerPlex® ESI kit for routine use. The Promega Company updated this kit and developed the PowerPlex® ESI 16 Fast System in which all autosomal primer pairs remained identical to the original set, except at the amelogenin site. The master mix was improved and optimized which allowed for(More)
To improve and advance DNA forensic casework investigation outcomes, extensive field and laboratory experiments are carried out in a broad range of relevant branches, such as touch and trace DNA, secondary DNA transfer and contamination confinement. Moreover, the development of new forensic tools, for example new sampling appliances, by commercial companies(More)
Detecting prostate specific antigen (PSA) in a questioned body fluid stain or other sexual assault casework items strongly indicates the presence of semen and is extremely useful when no sperm cells are observed. However, it has several false-positives which may prevent confirmative semen classification. Namely, the presence of PSA and nucleated cells in(More)
The aim of this work was to investigate the possibility of secondary and tertiary DNA transfer during laundry. The modes of transfer tested were mixed and separate laundry of worn and unworn garments in household and public washing machines. In addition, the possibility of a background DNA carry-over from a washing machine’s drum was investigated. In the(More)
