Millets and Herders: The Origins of Plant Cultivation in Semiarid North Gujarat (India)

Botanical evidence suggests that North Gujarat (India) was a primary center of plant domestication during the mid-Holocene. However, lack of systematic archaeobotanical research and significant taphonomic processes have so far hampered the possibility of substantiating this hypothesis. This paper explores the role of plants in the subsistence strategies of early-middle Holocene populations in this semiarid region and the processes leading to plant cultivation. To do so, we carry out a multiproxy archaeobotanical study —integrating macro and microbotanical remains— at two hunter-gatherer and agropastoral occupations. The results show that the progressive weakening of the Indian summer monsoon ca. 7,000 years ago compelled human populations to adopt seminomadic pastoralism and plant cultivation, which resulted in the domestication of several small millet species, pulses, and sesame.Peer Reviewe

Navigating surgical anatomy of the Denonvilliers' fascia and dissection planes of the anterior mesorectum with a cadaveric simulation model

Anterior dissection of the rectum in the male pelvis represents one of the most complex phases of total meso-rectal excision. However, the possible existence of different anatomical planes is controversial and the exact anatomical topography of Denonvilliers' fascia is still debated. The aim of the study is to accurately define in a cadaveric simulation model the existence and boundaries of Denonvilliers' fascia, identifying the anatomical planes suitable for surgical dissection. The pelvises of 31 formalin-preserved male cadavers were dissected. Careful and detailed dissection was carried out to visualize the anatomical structures and the potential dissection planes, simulating an anterior meso-rectum dissection. Denonvilliers' fascia was identified in 100% of the pelvises, as a single-layer fascia that originates from the peritoneal reflection and descends until its firm adhesion to the prostate capsule. The fascia divides the space providing an anterior and a posterior plane. Anteriorly to the fascia, during the caudal dissection, its firm adhesion to the prostate capsule forces to section it sharply. The cadaveric simulation model allowed an accurate description of Denonvilliers' fascia, defining several planes for anterior dissection of the meso-rectum

From Storage to Disposal: a Holistic Microbotanical Approach to Domestic Plant Preparation and Consumption Activities in Late Minoan Gypsades, Crete

The analysis of microbotanical remains (starch grains and phytoliths) from food-related domestic contexts and artefacts has the potential to provide insights into daily plant preparation and consumption activities. In particular, pottery vessels offer an unparalleled comparative framework for the study of food preparation and consumption, since pottery is used for a variety of domestic food-related activities, including storage, processing and serving. This study illustrates the potential of microbotanical remains to provide a holistic approach to the plant food preparation and consumption cycle—from storage to disposal—through the analysis of starch grains and phytoliths from Late Minoan storage, cooking and serving vessels recently uncovered at the Knossian ‘neighbourhood’ of Lower Gypsades. The results show that starch grains and phytoliths are more abundant and diverse in cooking vessels, presumably reflecting a higher deposition of microbotanical remains as a result of the disturbance caused by cooking. The results further offer insights into Minoan storage and cooking practices at Gypsades, suggesting that cereals were stored de-husked in pithoi and, possibly, in palm leaf baskets, and later cooked together with non-staple plants. The virtual absence of microbotanical remains from serving vessels may be due to depositional factors and/or the fact that some of the vessels analysed in this study were used for serving/consuming liquids or animal products, and not plants.The project was made possible with funds provided by INSTAP (EH, GA, AB); Semple Fund, Department of Classics, University of Cincinnati (EH); ERC Grant No. 312785 (AB); Fell Fund, University of Oxford (AB); the British Academy Grant No. SG152915 (AB); and the BSA.

Resilience of small-scale societies’ livelihoods: a framework for studying the transition from food gathering to food production

The origins of agriculture and the shift from hunting and gathering to committed agriculture is regarded as one of the major transitions in human history. Archeologists and anthropologists have invested significant efforts in explaining the origins of agriculture. A period of gathering intensification and experimentation and pursuing a mixed economic strategy seems the most plausible explanation for the transition to agriculture and provides an approach to study a process in which several nonlinear processes may have played a role. However, the mechanisms underlying the transition to full agriculture are not completely clear. This is partly due to the nature of the archeological record, which registers a practice only once it has become clearly established. Thus, points of transitions have limited visibility and the mechanisms involved in the process are difficult to untangle. The complexity of such transitions also implies that shifts can be distinctively different in particular environments and under varying historical and social conditions. In this paper we discuss some of the elements involved in the transition to food production within the framework of resilience theory. We propose a theoretical conceptual model in which the resilience of livelihood strategies lies at the intersection of three spheres: the environmental, economical, and social domains. Transitions occur when the rate of change, in one or more of these domains, is so elevated or its magnitude so large that the livelihood system is unable to bounce back to its original state. In this situation, the system moves to an alternative stable state, from one livelihood strategy to another.This paper is the result of a two-day workshop funded by ICREA (Catalan Higher Research Institution) and organized at the ICTA (Institute for Environmental Studies) of the Autonomous University of Barcelona and the Department of Humanities of the Universitat Pompeu Fabra.

Mechanical barriers and transforming growth factor beta inhibitor on epidural fibrosis in a rabbit laminectomy model

Background: TGF-β has been described as a mediator of fibrosis and scarring. Several studies achieved reduction in experimental scarring through the inhibition of TGF-β. Fibroblasts have been defined as the cell population originating fibrosis, blocking fibroblast invasion may impair epidural fibrosis appearance. For this purpose, biocompatible materials used as mechanical barriers and a TGF-β inhibitor peptide were evaluated in the reduction of epidural fibrosis. Methods: A L6 laminectomy was performed in 40 New Zealand white rabbits. Divided into four groups, each rabbit was assigned to receive either collagen sponge scaffold (CS group), gelatin-based gel (GCP group), P144® (iTGFβ group), or left untreated (control group). Four weeks after surgery, cell density, collagen content, and new bone formation of the scar area were determined by histomorphometry. Two experienced pathologists scored dura mater adhesion, scar density, and inflammatory infiltrate in a blinded manner. Results: In all groups, laminectomy site was filled with fibrous tissue and the dura mater presented adhesions. Only GCP group presented a significant reduction in collagen content and scar density. Conclusion: GCP treatment reduces epidural fibrosis although did not prevent dura mater adhesion completely

The Late Copper Age building BII-21B at Tell Yunatsite, south central Bulgaria

This paper considers the structure investigated at the largest area (labeled as BII-21B) in the Chalcolithic level BII of Tell Yunatsite, located in the western parts of the Upper Thracian Plain. It collapsed during a sudden fire, which did not affect the neighboring house to the west. The debris sealed a large number of fragmented vessels, plant remains, and even some of the inhabitants. Detailed analysis of the materials found allows for a reconstruction of diet and storage practices, research on vessels’ function and technology, decoration styles, etc. The plant remains are abundant and demonstrate a diverse species composition. The complex is dominated by lentils, barley, and einkorn wheat. Of particular interest is the evidence on purposeful gathering of grapes for producing a drink, perhaps wine. The investigation of the ceramic assemblage shows that it belongs to a developed – but not final – stage of the Late Copper Age in Upper Thrace. It also provides new information about the contact zone between the Karanovo VI and Krivodol cultures in this area
