A number of charred surface residues, adhering to ceramic containers, were obtained from various coastal and inland sites in north‐west Europe dating the sixth fourth millennium cal bc . In order investigate use these vessels particular identify any marine products, residues subjected carbon nitrogen stable isotope analysis. Variation ratios between different samples indicated that some may have been used process products. This analysis was corroborated by specific identification aquatic...
Individuals with inflammatory bowel disease (IBD) are at increased risk of developing anxiety or depression (A&D). Crohn's (CD) and ulcerative colitis (UC) comorbid A&D both more challenging to manage. IBD providers need better understand the causes impact in order improve care for patients. We sought identify clinical factors that influence development healthcare utilization IBD. This is a retrospective analysis using an natural history registry from single tertiary referral center....
Significance Climate change increases the frequency of drought events and leads to higher variability in precipitation. Drought impairs rhizosphere (root root-associated microbiome) functioning trees a reduced assimilate supply belowground. It remains unclear if thus whole-tree can quickly recover after release. We show that metabolic activity previously drought-exposed 100-y-old Scots pine increased response subtle soil moisture (induced by light rainfall). As consequence this change,...
Abstract Individual n‐alkalines isolated from the leaf‐surface waxes of plants utilizings differing photosynthetic pathways were analysed using gas chromatography/isotope mass spectrometry (GC/IRMS), in order to obtain ratios 13 C 12 (δ ). Marked differences average C‐depletion relative whole leaf tissues observed (C 3 = −7.7‰; 4 −9.9‰; CAM −11‰). Additionally, all three metabolic types exhibited considerable between n‐alkaline homologues same plant.
In contrast with artefactual studies of long‐distance trade and exchange in South Asia during the Prehistoric Early Historic periods ( Ardika et al. 1993 ; Gogte 1997 Krishnan Coningham Tomber 2000 Gupta 2001 Ford 2005 ), few scientifically orientated analyses have focused on artefacts from region's period. During excavations at ancient city Anuradhapura, Sri Lanka, a number buff ware ceramics putative organic coating interior were recovered 2006 ). Dated stylistically to between third ninth...
Abstract Background and Aims NASH is a common disease associated with increased rates of thromboembolism (TE). Although exercise training can lessen thrombotic risk in patients vascular disease, whether similar findings are observed open for study. Approach Results We conducted 20‐week randomized controlled clinical trial involving biopsy‐confirmed NASH. Patients were randomly assigned (2:1 ratio) to receive either an program or standard care. The primary endpoint was change plasminogen...
This study examines resinous deposits from the interior surfaces of sherds imported Canaanite amphorae and locally produced bowls 18th Dynasty site Tell el‐Amarna, Egypt. Archaeological evidence indicates that were used for resin transport, whilst are associated with burning as incense. A number characteristic triterpenoids identify all both vessel types Pistacia spp. No other resins observed there was no mixing oils or fats. The composition archaeological is more complex than modern...

Abstract Resinous substances were highly prized in the ancient world for use ritual contexts. Details gleaned from classical literature indicate that they played a significant role Roman mortuary rites, treatment of body and as offerings at tomb. Outside Egypt, however, where research has shown range plant exudates applied part mummification process, resins have rarely been identified burial record. This is despite considerable speculation regarding their across Empire. Focusing on one...
Canaanite amphorae fragments in fabrics believed to be associated with the bulk transport of vegetable oils from fourteenth‐century BC site Amarna, Egypt, have been examined. A comparison is made between solvent extraction, saponification and use TMTFTH (m‐trifluoromethylphenyl)trimethylammomum hydroxide, used here for combined extraction derivatization ceramic‐absorbed organic residues. Extracts were studied using gas chromatography chromatography‐mass spectrometry. The fatty acids small...
Pottery of the Rouletted ware family belongs to India’s Early Historic period (c. 500 BC c. AD 200) and has been found as far east Bali in Indonesia west Berenike Egypt. Although they appear similar Mediterranean products, scientific tests by authors show that Arikamedu Type 10 Sri Lankan Grey had a common geological origin India. Since at least pre-dates arrival Roman pottery India, all these related wares were probably products indigenous communities.
Background Most patients with nonalcoholic fatty liver disease (NAFLD) are physically inactive despite the well-known benefits of physical activity. Telehealth offers promise as a novel way to deliver an exercise training program and increase However, feasibility, safety, efficacy telehealth-based programs is unknown in NAFLD. Objective The aim this study was determine feasibility directly supervised delivered exclusively telehealth steatohepatitis (NASH), progressive form Methods In...
Pottery found at Spirit Cave, Thailand, has been claimed as among the earliest ceramics in world – a radiocarbon date of 7500 BP being obtained from associated charcoal. However dating organic resin on some sherds gave around 3000 BP. This is another example improved precision by pin-pointing context and using AMS. The authors describe how it was done assess its validity
There is increasing evidence for complexity in mortuary practices B ritain during the R oman period. One class of burials demonstrates an association between inhumation stone sarcophagi or lead‐lined coffins, ‘plaster’ coatings, textile shrouds and natural resins. It has been suggested that this ‘package’ represents a deliberate attempt at body preservation. Fragments with resinous appearance found one such burial from A rrington, C ambridgeshire, UK were analysed using gas...
We have applied and refined methods for the determination of bulk hydrogen, carbon oxygen isotope ratios in modern archaeological resins. The resins a wide range isotopic values vary within same tree, between individual trees, with species location. For all isotopes measured, there is general trend increasing depletion heavier altitude. There also linear δD δ 13 C latitude; this less clear oxygen, but related to meteoric water line. Two case studies using known or suspected been transported...
