The Epipaleolithic Natufian culture (/nəˈtuːfiən/) existed from around 12,500 to 9,500 BC in the Levant, a region in the Eastern Mediterranean. The culture was unusual in that it supported a sedentary or semi-sedentary population even before the introduction of agriculture. The Natufian communities may be the ancestors of the builders of the first Neolithic settlements of the region, which may have been the earliest in the world.[citation needed] Natufians founded Jericho which may be the oldest city in the world. Some evidence suggests deliberate cultivation of cereals, specifically rye, by the Natufian culture, at Tell Abu Hureyra, the site of earliest evidence of agriculture in the world. Generally, though, Natufians exploited wild cereals. Animals hunted included gazelles. According to Christy G. Turner II, there is archaeological and physical anthropological evidence for a relationship between the modern Semitic-speaking populations of the Levant, Persian Gulf and the Natufians. However ...

The information required for adequate diagnosis, treatment and monitoring of cancers is so complex that a panel of measurements, used in sum, may provide the best answers. The concept is embodied in SELDI-TOF mass spectrometric (MS) peptide profiling, an emerging technique for serum based cancer detection. Even though SELDI has thus far only produced low complexity spectra, the patterns, when analyzed as groups, have the potential to create learning algorithms with diagnostic accuracies as good as or better than conventional biomarkers. We have developed a system to capture peptides on magnetic reversed-phase beads, followed by MALDI-TOF MS, to yield increasingly complex, yet very reproducible patterns. This has clear advantages, as more displayed peptides provide more opportunity to select unique patterns (barcodes) for cancer subtypes and stages, and to predict and monitor clinical outcome. Extreme care has also been taken to standardize specimen collection, handling and storage to avoid the ...
Recent development of novel technologies paved the way for quantitative proteomics. One of the most important among them is iTRAQ, employing isobaric tags for relative or absolute quantitation. Despite large progress in technology development, still many challenges remain for derivation and interpretation of quantitative results. One of these challenges is the consistent assignment of peptides to proteins. We have developed Peptide Profiling Guided Identification of Proteins (PPINGUIN), a statistical analysis workflow for iTRAQ data addressing the problem of ambiguous peptide quantitations. Motivated by the assumption that peptides uniquely derived from the same protein are correlated, our method employs clustering as a very early step in data processing prior to protein inference. Our method increases experimental reproducibility and decreases variability of quantitations of peptides assigned to the same protein. Giving further support to our method, application to a type 2 diabetes dataset identifies

In 1987, the remains of an 18-22-year-old woman, now dubbed Ava, were discovered at Achavanich in Caithness in the north of Scotland. The site was excavated by the Highland Regional Council Archaeology Unit, and the burial was later dated to the Middle Bronze Age. Although the discovery is interesting, and one aspect of it has been hotly debated by researchers, it was soon forgotten by most people. Now, an archaeologist is working to change that. Archaeologist Maya Hoole hopes to renew public interest in the burial from about 3,700 years ago. As she told the BBC , "Like many others, Im sure, I find skeletal remains completely mesmerising." On Hooles website, the Achavanich Beaker Burial Project , she explains her goal further: "I had one objective when I started this project: to change our understanding of this site and, over the last year, have been trying to make this happen." Hoole believes that a renewed interest and modern technology could make this happen, revealing much more about the ...
We compared the burial efficiency of organic carbon (buried OC: deposited OC) in a diverse set of 27 different sediments from 11 lakes, focusing on the potential effects of organic matter source, oxygen exposure, and protective sorption of OC onto mineral surfaces. Average OC burial efficiency was high (mean 48%), and it was particularly high in sediments receiving high input of allochthonous organic matter (mean 67%). Further, OC burial efficiency was strongly negatively related to the oxygen exposure time, again particularly so in sediments receiving high allochthonous loads. On the other hand, OC burial efficiency was not related to the mineral surface area, which was used as a proxy of the sorption capacity of the mineral phase for OC. The high OC burial efficiency in many lake sediments can thus be attributed to the frequent and significant input of allochthonous organic matter to lakes, as well as to a strong dependence of OC burial efficiency on oxygen exposure time. This study ...

Known as Tel Kabri (located near its namesake kibbutz not far from historic Acco and the resort town of Nahariya on the coast of Israel), the site features an early Middle Bronze Age (MB I) palace dated to the 19th century B.C.E., making it, along with ancient Aphek and possibly Megiddo, the earliest MB palace discovered in present-day Israel. This conclusion was drawn as a result of excavations conducted there as recently as December 20, 2010 to January 10, 2011. But the tell-tale signs of an Aegean presence or influence at the site show up in a later developmental phase of the palace structure some 150 to 200 years later in the overlying MB II palace dated to the 17th century.

Post mortem or even normal changes during life occurring in major gut bacterial populations are not known. We investigated Bacteroides sp., Bifidobacterium sp., Clostridium leptum, Clostridium coccoides, Streptococcus sp., Lactobacillus sp. and Enterobacteriacaea ratios in 7 fecal samples from healthy volunteers and in 61 autopsies rectum and cecum samples and studied the effect of post mortem time using quantitative real-time PCR. Bacterial ratios in stool samples from volunteers and rectum samples from autopsy cases were similar and did not change significantly up to 5 days post mortem. In cecum, significant post mortem time-dependent differences were observed in ratios of Bacteroides sp. (p = 0.014) and Lactobacillus sp. (p = 0.024). Our results showed that ratios of Bacteroides sp., Bifidobacterium sp., Clostridium leptum, Clostridium coccoides, Streptococcus sp., Lactobacillus sp. and Enterobacteriacaea can be investigated in autopsy rectum samples up to 5 days after death.

In this study, redox-dependent phosphorus (P) recycling and burial at 6 sites in the Baltic Sea is investigated using a combination of porewater and sediment analyses and sediment age dating (Pb-210 and Cs-117). We focus on sites in the Kattegat, Danish Straits and Baltic Proper where present-day bottom water redox conditions range from fully oxygenated and seasonally hypoxic to almost permanently anoxic and sulfidic. Strong surface enrichments of Fe-oxide bound P are observed at oxic and seasonally hypoxic sites but not in the anoxic basins. Reductive dissolution of Fe-oxides and release of the associated P supports higher sediment-water exchange of PO4 at hypoxic sites (up to similar to 800 mu mol P m(-2) d(-1)) than in the anoxic basins. This confirms that Fe-bound P in surface sediments in the Baltic acts as a major internal source of P during seasonal hypoxia, as suggested previously from water column studies. Most burial of P takes place as organic P. We find no evidence for significant ...
Elizabeth Alesi supervised the excavation of a cyst grave discovered in the layer directly beneath the Parthian building foundations. The burial in locus 124025 consisted of a large storage jar and smaller pot that were placed mouth to mouth to form the coffin. This style of burial is identical to burials discovered at Tell Bweid (downstream approximately 4 km. from Tuneinir) by Dr. Antoine Sulieman from the Aleppo Museum. The burials at Tell Bweid were definitely from the Neo-Assyrian Period; the jar burial in locus 124025 may be Neo-Assyrian. We have not excluded the possibility that the burial is from the Persian Period ...

Stephen Bauld, procurement expert. According to experts in the government procurement business, the city should have been upfront with any information it knew of contamination and burials in the initial request for expression of interest (RFEI) that attracted developers, like Furbacher.. Stephen Bauld literally wrote the book on it, called Municipal Procurement, and is considered a leading expert.. Bauld said he has reviewed documents of what happened between Barrie and Furbacher.. "This is a travesty for First Nations people, " said Bauld. "This is the one of the worst things Ive ever seen, maybe ever.". Architect Jim Strasman was hired by the city to design the sites master plan for the REFI and said he was never told of the documented burials or possible contamination.. "Thats a show stopper," said Strasman. "You would down tools immediately until that was somehow resolved.". But, after Furbacher refused to sign the purchase agreement the city hired Golder Associates, a soil testing firm ...

Numerous industrial or burial sites contaminated by persistent organic pollutants such as polychlorinated biphenyls (PCBs) and pesticides were discovered in China recently. Due to improper choice of technology, many remediation cases had cost too much; however, failed to attain expected goals. In this study, the distribution and transport of PCBs at a burial site were investigated using tested PCBs concentration in order to support the choice of remediation technology and estimate the remediation results. Site characterization was carried out in order to investigate the hydrogeological condition and PCBs pollution nearby the capacitor burial site located in Shanxi, China. Results of PCBs measurement indicated that the proportion of contaminated soil with concentration above 500 mg/kg is 7.8 % and the value for soil with concentration between 50 and 500 mg/kg is 18.0 %. Considering adsorption and biodegradation, the two-dimensional PCBs transport model was established based on ...
