Excavations below the A.D. 79 destruction levels in two houses at the Roman town of Pompeii, Italy included programmes of sieving and flotation for the recovery of biological remains. In addition to the usual finds of charred plant material and bones representing crop processing or food waste, and mineralised remains from sewage, were numerous burnt offerings. Cones and seeds of stone pine, fruit such as fig and grape and nuts such as walnut and hazel were present in many of them. Some of the offerings contained burnt bone, with the heads and feet of cocks (male domestic fowl) being particularly well represented. There was some change in the plants and animals used for the burnt offerings with time. These offerings could be related to domestic worship described in literary sources and depicted as offerings on altars in Pompeiian wall paintings at shrines to the Lares (household gods). The burnt offerings resulted in the preservation by charring of fruit that are not usually burnt during their processing for consumption. They also presented a taphonomic problem because re-worked charred material from burnt offerings was likely to have been a major component of other charred assemblages from the sites.

Presence and features of auditory exostoses were investigated in two cranial samples of Roman imperial age (1st-3rd century A.D.). The skeletal material comes from the necropolises of Portus (Isola Sacra) and Lucus Feroniae (Via Capenate), two towns along the Tevere River, in close relation with the social and economic life of Rome. Deep-rooted differences between the human communities represented by the skeletal samples (83 and 71 individuals, respectively, in this study) are documented both historically and archaeologically. The results show lack of exostoses in the female sex, a negligible incidence among the males of Lucus Feroniae, but a high frequency in the male sample from Isola Sacra (31.3%). Auditory exostoses are commonly recognised as localized hyperplastic growths of predominantly acquired origin. Features of the exostoses found in the male crania from Isola Sacra (particularly in relation to the age at death of the affected individuals) support this view. Furthermore, several clinical and anthropological studies have pointed out close links between the occurrence of auditory exostoses and prolonged cold water exposure, generally due to the practice of aquatic sports, or to working activities involving water contact or diving. In this perspective, the differences observed between the two Roman populations and between the sexes (in Isola Sacra) appear to result from different social habits: the middle class population of Portus habitually used thermal baths, whereas it is probable that thermae were seldom frequented (if at all) by the Lucus Feroniae population represented in the necropolis (mostly composed by slaves or freedmen farm laborers).(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

Objectives

We investigated the neural basis of hallucinations Alzheimer''s disease (AD) by applying voxel-based morphometry (VBM) to anatomical and functional data from the AD Neuroimaging Initiative.

Methods

AD patients with hallucinations, based on the Neuropsychiatric Inventory (NPI-Q) (AD-hallu group; n = 39), were compared to AD patients without hallucinations matched for age, sex, educational level, handedness and MMSE (AD-c group; n = 39). Focal brain volume on MRI was analyzed and compared between the two groups according to the VBM method. We also performed voxel-level correlations between brain volume and hallucinations intensity. A similar paradigm was used for the PET analysis. “Core regions” (i.e. regions identified in both MRI and PET analyses, simply done by retaining the clusters obtained from the two analyses that are overlapping) were then determined.

Results

Regions with relative atrophy in association with hallucinations were: anterior part of the right insula, left superior frontal gyrus and lingual gyri. Regions with relative hypometabolism in association with hallucinations were a large right ventral and dorsolateral prefrontal area. "Core region" in association with hallucinations was the right anterior part of the insula. Correlations between intensity of hallucinations and brain volume were found in the right anterior insula, precentral gyrus, superior temporal gyrus, and left precuneus. Correlations between intensity of hallucinations and brain hypometabolism were found in the left midcingulate gyrus. We checked the neuropathological status and we found that the 4 patients autopsied in the AD-hallu group had the mixed pathology AD and Dementia with Lewy bodies (DLB).

Conclusion

Neural basis of hallucinations in cognitive neurodegenerative diseases (AD or AD and DLB) include a right predominant anterior-posterior network, and the anterior insula as the core region. This study is coherent with the top-down/bottom-up hypotheses on hallucinations but also hypotheses of the key involvement of the anterior insula in hallucinations in cognitive neurodegenerative diseases.  相似文献

Among partly mixed collection of skeletal remains excavated in the house called “Casa di Polibio” skeletons of 13 individuals were re-assembled and identified. There were 3 adult males, 3 adult females of various ages, 4 boys, 1 girl, child of unknown sex and one foetus in the last month of intrauterine life. The foetus was associated with the skeleton of a young (16–18 years) female whose bones are stained green-blue-black, probably by the jewellery or costume. Craniometric, odontometric, and osteometric data, together with reconstruction of stature are presented. Besides a mild case of torticollis in a young adult male no special pathologies were found. Enamel hypoplasia was frequent (87.5%). Presence of dental calculus on teeth of practically all individuals, frequent dental caries (63.6% of individuals), and moderate tooth wear indicate diet of well-cooked foods rich in carbohydrates. On grounds of age and biological characteristics it may be suggested that the group included older parents, their children, eldest son and his pregnant young wife plus a pair of domestics. Other possibilities include three adult couples: grandparents, parents and newlywed eldest daughter and her husband. Final resolution of family relationships must await full analysis of metric data and the DNA analysis. It seems that the group is representative of a Pompeian household: many children born approximately 3 years apart, early age at marriage, good food, relative freedom from disfiguring disease.  相似文献

A field experiment was carried out to evaluate the growth response of Pinus halepensis seedlings inoculated with Pisolithus arhizus and planted in a terraced rangeland amended with urban solid refuse. The application of the organic amendment mediated a significant increase in soil fertility and soil water content. Twenty seven months after planting seedling survival rates did not differ significantly among treatments and were above 95% in all cases. Growth of P. halepensis was significantly (p<0.01) enhanced by the refuse application independently of their mycorrhizal status at the beginning of the experiment. A multiple regression analysis including available soil P concentration and sorptivity as independent variables explained up to 60% of the variance in pine growth observed across treatments. Inoculation with P. arhizus also significantly (p<0.01) enhanced pine growth with repect to the controls grown in both amended and nonamended plots. It was conduded that the combination of soil terracing, refuse amendment and P. arhizus inoculation significantly improved the performance of Pinus halepensis, and this methodology could be successfully applied in afforestation programmes in semiarid and degraded sites.  相似文献

Fasting triggers a constellation of physiological and behavioral changes, including increases in peripherally produced ghrelin and centrally produced hypothalamic neuropeptide Y (NPY). Refeeding stimulates food intake in most species; however, hamsters primarily increase foraging and food hoarding with smaller increases in food intake. Fasting-induced increases in foraging and food hoarding in Siberian hamsters are mimicked by peripheral ghrelin, central NPY, and NPY Y1 receptor agonist injections. Because fasting stimulates ghrelin and subsequently NPY synthesis/release, it may be that fasting-induced increased hoarding is mediated by NPY Y1 receptor activation. Therefore, we asked: Can an Y1 receptor antagonist block fasting- or ghrelin-induced increases in foraging, food hoarding, and food intake? This was accomplished by injecting the NPY Y1 receptor antagonist 1229U91 intracerebroventricularly in hamsters fasted, fed, or given peripheral ghrelin injections and housed in a running wheel-based food delivery foraging system coupled with simulated-burrow housing. Three foraging conditions were used: 1) no running wheel access, free food, 2) running wheel access, free food, or 3) foraging requirement (10 revolutions/pellet) for food. Fasting was a more potent stimulator of foraging and food hoarding than ghrelin. Concurrent injections of 1229U91 completely blocked fasting- and ghrelin-induced increased foraging and food intake and attenuated, but did not always completely block, fasting- and ghrelin-induced increases in food hoarding. Collectively, these data suggest that the NPY Y1 receptor is important for the effects of ghrelin- and fasting-induced increases in foraging and food intake, but other NPY receptors and/or other neurochemical systems are involved in increases in food hoarding.  相似文献

This paper discusses archaeobotanical remains from the settlement mound of Kursakata, Nigeria, comprising both charred and uncharred seeds and fruits as well as charcoal. In addition, impressions of plant tempering material in potsherds were analysed. The late Stone Age and Iron Age sequence at Kursakata is date from 1000 cal. B.C. to cal. A.D. 100. DomesticatedPennisetum (pearl millet), wild Paniceae and wild rice are the most common taxa. Kernels from tree fruits were regularly found including large numbers ofVitex simplicifolia—a tree which is absent from the area today. A distinct change in plant spectra can be observed between the late Stone Age and the Iron Age. Although domesticated pearl millet was already known at the beginning of the settlement sequence of Kursakata, it only gained greater economic importance during the Iron Age. Besides farming, pastoralism and fishing, gathering of wild plants always played a major role in the subsistence strategy of the inhabitants of Kursakata. The charcoal results show that firewood was mainly collected from woodlands on the clay plains, which must have been more diverse than today. The end of the late Stone Age in the Chad Basin was presumably accompanied by the onset of drier environmental conditions from ca. 800 cal. B.C. onwards.  相似文献

Introduction

Obsessive-compulsive disorder (OCD) is a common and chronic condition that can have disabling effects throughout the patient''s lifespan. Frequent symptoms among OCD patients include fear of contamination and washing compulsions. Several studies have shown a link between contamination fears, disgust over-reactivity, and insula activation in OCD. In concordance with the role of insula in disgust processing, new neural models based on neuroimaging studies suggest that abnormally high activations of insula could be implicated in OCD psychopathology, at least in the subgroup of patients with contamination fears and washing compulsions.

Methods

In the current study, we used a Brain Computer Interface (BCI) based on real-time functional magnetic resonance imaging (rtfMRI) to aid OCD patients to achieve down-regulation of the Blood Oxygenation Level Dependent (BOLD) signal in anterior insula. Our first aim was to investigate whether patients with contamination obsessions and washing compulsions can learn to volitionally decrease (down-regulate) activity in the insula in the presence of disgust/anxiety provoking stimuli. Our second aim was to evaluate the effect of down-regulation on clinical, behavioural and physiological changes pertaining to OCD symptoms. Hence, several pre- and post-training measures were performed, i.e., confronting the patient with a disgust/anxiety inducing real-world object (Ecological Disgust Test), and subjective rating and physiological responses (heart rate, skin conductance level) of disgust towards provoking pictures.

Results

Results of this pilot study, performed in 3 patients (2 females), show that OCD patients can gain self-control of the BOLD activity of insula, albeit to different degrees. In two patients positive changes in behaviour in the EDT were observed following the rtfMRI trainings. Behavioural changes were also confirmed by reductions in the negative valence and in the subjective perception of disgust towards symptom provoking images.

Conclusion

Although preliminary, results of this study confirmed that insula down-regulation is possible in patients suffering from OCD, and that volitional decreases of insula activation could be used for symptom alleviation in this disorder.  相似文献

The urban archaeological excavations carried out in the city of Lleida (Catalonia, Spain) have opened the way for an interdisciplinary project on the ancient landscape, agriculture and food. Here we present the results of the archaeobotanical study of seeds and fruits from this project, centred on the Roman and Islamic periods of the city, between the 2nd century B.C. and the 11th century A.D. During the whole of this period the cultivation and consumption of cereals was found. The most important cereals were hulled barley and naked wheat. This was already known from the later prehistoric era in the area and is similar to findings at other sites from the same period in the western Mediterranean. These cereals are accompanied by some leguminous crops and the presence of grapes and figs is very significant. The expansion of vine cultivation, together with a certain amount of tree growing was one of the basic contributions of the Roman world to proto-historical (Bronze- and Iron Age) agriculture in western Catalonia, as in other parts of Europe. In the Islamic period, there seems to have been an increase in the number of fruit tree species; however for taphonomical reasons this has to be confirmed by future investigations. Flax, already known in prehistoric times, and Gold-of-pleasure must be added to the finds. Also since the Roman period some other taxa, such as celery or fennel, might have been grown. During the time period considered in this paper, there was a wide range of plants grown and consumed. This clearly contrasts with everything known about earlier periods in western Catalonia, during which the only cultivated plants were cereals and flax.  相似文献
