Envelhecimento, linguagem e memória visuo-espacial: um estudo comparativo exploratório do desempenho humano em testes neuropsicológicos selecionados

O reconhecimento dos limites entre o envelhecimento normal e o patológico é essencial para a adoção de políticas de saúde baseadas em evidências para o grupo etário acima de 65 anos. Este estudo é parte de um esforço sistemático que o grupo de pesquisa do Laboratório de Investigações em Neurodegeneração e Infecção da Universidade Federal do Pará tem feito para fornecer informações translacionais sobre a neurobiologia do envelhecimento normal e alterada. A meta principal em longo prazo é permitir políticas públicas para o envelhecimento saudável na Região Amazônica. No presente trabalho investigamos os efeitos do envelhecimento sobre os desempenhos em testes neuropsicológicos selecionados para avaliar aprendizagem, memória e alterações de linguagem. 29 adultos jovens (29,9 ± 1,06 anos) e 31 idosos (74,1 ± 1,15 anos) saudáveis foram submetidos aos testes e os resultados de seus desempenhos foram comparados por testes paramétricos e estatística multivariada. Uma anamnese e uma variedade de testes cognitivos, incluindo Mini Exame do Estado Mental, tarefas visuo-espaciais de aprendizagem e de memória da bateria de testes neuropsicológicos automatizados - CANTAB e testes de linguagem incluindo fluência verbal semântica e fonológica, teste de nomeação de Boston reduzido, performance narrativa utilizando a figura “o roubo dos biscoitos” e alguns testes da Bateria Montreal de Comunicação - MAC. O programa BioEstat versão 5.0 e o pacote estatístico SPSS foram utilizados para a análise. O teste paramétrico t de Student ou o não paramétrico de Mann-Whitney foram aplicados para detectar diferenças significativas (fixadas em valores de p <0,05). Os grupos foram pareados por escolaridade e incluiu homens e mulheres. A análise das subcategorias que compõem o MEEM mostrou diferença significativa apenas na recuperação da memória de evocação de lista de palavras, em que o grupo de idosos apresentou pior desempenho em comparação com o grupo de jovens. Foram encontradas diferenças estatisticamente significativas entre os desempenhos de idosos e jovens adultos nos seguintes testes de linguagem: 1) Nomeação de Boston, 2) Testes de Narrativa, 3) Metáforas; 4) Prosódia Emocional e Linguística. Em comparação com os adultos jovens, indivíduos idosos apresentaram pior desempenho em 10 medidas diferentes nos testes de memória visuo-espacial e de aprendizagem do CANTAB. Distâncias Euclidianas e análise discriminante obtidas a partir do CANTAB e dos testes de linguagem demonstraram que os primeiros distinguem os grupos com maior resolução. Os efeitos do envelhecimento sobre o desempenho nos testes neuropsicológicos selecionados revelam que a Bateria CANTAB, empregada para testar a memória visuo-espacial, é mais sensível e discrimina melhor a formação de subgrupos tanto no grupo de adultos jovens quanto no grupo de idosos. Por essa razão sugerimos que a aplicação em larga escala de testes selecionados da bateria CANTAB, tanto em estudos transversais como em longitudinais, vai aumentar nossa capacidade de resolução na distinção dos limites entre o envelhecimento normal e o patológico.

High-frequency TENS in post-episiotomy pain relief in primiparous puerpere: A randomized, controlled trial

Aim: We evaluated the effectiveness of high-frequency transcutaneous electrical nerve stimulation (TENS) as a pain relief resource for primiparous puerpere who had experienced natural childbirth with an episiotomy. Methods: A controlled, randomized clinical study was conducted in a Brazilian maternity ward. Forty puerpere were randomly divided into two groups: TENS high frequency and a no treatment control group. Post-episiotomy pain was assessed in the resting and sitting positions and during ambulation. An 11-point numeric rating scale was performed in three separate evaluations (at the beginning of the study, after 60 min and after 120 min). The McGill pain questionnaire was employed at the beginning and 60 min later. TENS with 100 Hz frequency and 75 mu s pulse for 60 min was employed without causing any pain. Four electrodes ware placed in parallel near the episiotomy site, in the area of the pudendal and genitofemoral nerves. Results: An 11-point numeric rating scale and McGill pain questionnaire showed a significant statistical difference in pain reduction in the TENS group, while the control group showed no alteration in the level of discomfort. Hence, high-frequency TENS treatment significantly reduced pain intensity immediately after its use and 60 min later. Conclusion: TENS is a safe and viable non-pharmacological analgesic resource to be employed for pain relief post-episiotomy. The routine use of TENS post-episiotomy is recommended.

Reprogramming of prostate cancer-associated stromal cells to embryonic stem-like

BACKGROUND CD90+ prostate cancer-associated (CP) stromal cells represent a diseased cell type found only in tumor tissue. They differ from their normal counterpart in gene expression and inductive signaling. Genetic reprogramming by induced pluripotent stem (iPS) cell technology can effectively change adult cells into stem-like cells through wholesale alteration of the gene expression program. This technology might be used to erase the abnormal gene expression of diseased cells. The resultant iPS cells would no longer express the disease phenotype, and behave like stem cells. METHODS CP stromal cells, isolated from tumor tissue of a surgically resected prostate by anti-CD90-mediated sorting and cultured in vitro, were transfected with in vitro packaged lentiviral expression vectors containing stem cell transcription factor genes POU5F1, LIN28, NANOG, and SOX2. RESULTS Alkaline phosphatase-positive iPS cells were obtained in about 3 weeks post-transfection at a frequency of 10-4. Their colony morphology was indistinguishable from that of human embryonic stem (ES) cells. Transcriptome analysis showed a virtually complete match in gene expression between the iPS and ES cells. CONCLUSIONS Genes of CP stromal cells could be fully inactivated by genetic reprogramming. As a consequence, the disease phenotype was cured. Prostate 72:14531463, 2012.

Effect of resonant tunneling on exciton dynamics in coupled dot-well nanostructures

Excitonic dynamics in a hybrid dot-well system composed of InAs quantum dots (QDs) and an InGaAs quantum well (QW) is studied by means of femtosecond pump-probe reflection and continuous wave (cw) photoluminescence (PL) spectroscopy. The system is engineered to bring the QW ground exciton state into resonance with the third QD excited state. The resonant tunneling rate is varied by changing the effective barrier thickness between the QD and QW layers. This strongly affects the exciton dynamics in these hybrid structures as compared to isolated QW or QD systems. Optically measured decay times of the coupled system demonstrate dramatically different response to temperature change depending on the strength of the resonant tunneling or coupling strength. This reflects a competition between purely quantum mechanical and thermodynamical processes.

Norm and difference : Stone Age dietary practice in the Baltic region

Stone Age research on Northern Europe frequently makes gross generalizations about the Mesolithic and Neolithic, although we still lack much basic knowledge on how the people lived. The transition from the Mesolithic to the Neolithic in Europe has been described as a radical shift from an economy dominated by marine resources to one solely dependent on farming. Both the occurrence and the geographical extent of such a drastic shift can be questioned, however. It is therefore important to start out at a more detailed level of evidence in order to present the overall picture, and to account for the variability even in such regional or chronological overviews. Fifteen Stone Age sites were included in this study, ranging chronologically from the Early Mesolithic to the Middle or Late Neolithic, c. 8300–2500 BC, and stretching geographically from the westernmost coast of Sweden to the easternmost part of Latvia within the confines of latitudes 55–59° N. The most prominent sites in terms of the number of human and faunal samples analysed are Zvejnieki, Västerbjers and Skateholm I–II. Human and faunal skeletal remains were subjected to stable carbon and nitrogen isotope analysis to study diet and ecology at the sites. Stable isotope analyses of human remains provide quantitative information on the relative importance of various food sources, an important addition to the qualitative data supplied by certain artefacts and structures or by faunal or botanical remains. A vast number of new radiocarbon dates were also obtained. In conclusion, a rich diversity in Stone Age dietary practice in the Baltic Region was demonstrated. Evidence ranging from the Early Mesolithic to the Late Neolithic show that neither chronology nor location alone can account for this variety, but that there are inevitably cultural factors as well. Food habits are culturally governed, and therefore we cannot automatically assume that people at similar sites will have the same diet. Stable isotope studies are very important here, since they tell us what people actually consumed, not only what was available, or what one single meal contained. We should not be deceived in inferring diet from ritually deposited remains, since things that were mentally important were not always important in daily life. Thus, although a ritual and symbolic norm may emphasize certain food categories, these may in fact contribute very little to the diet. By the progress of analysis of intra-individual variation, new data on life history changes have been produced, revealing mobility patterns, breastfeeding behaviour and certain dietary transitions. The inclusion of faunal data has proved invaluable for understanding the stable isotope ecology of a site, and thereby improve the precision of the interpretations of human stable isotope data. The special case of dogs, though, demonstrates that these animals are not useful for inferring human diet, since, due to the number of roles they possess in human society, dogs could deviate significantly from humans in their diet, and in several cases have been proved to do so. When evaluating radiocarbon data derived from human and animal remains from the Pitted-Ware site of Västerbjers on Gotland, the importance of establishing the stable isotope ecology of the site before making deductions on reservoir effects was further demonstrated. The main aim of this thesis has been to demonstrate the variation and diversity in human practices, challenging the view of a “monolithic” Stone Age. By looking at individuals and not only at populations, the whole range of human behaviour has been accounted for, also revealing discrepancies between norm and practice, which are frequently visible both in the archaeological record and in present-day human behaviour.

Riabilitazione protesica ed implanto-protesica di pazienti in età evolutiva affetti da Displasia Ectodermica

Introduction. Ectodermal Dysplasias are a heterogeneous group of inherited disorders characterized by dysplasia of tissues of ectodermal origin (hair, nails, teeth, skins and glands). Clinically, it may be divided into two broad categories: the X-linked hypoidrotic form and the hidrotic form. Hypohidrotic Ectodermal Dysplasia (H.E.D) is characterized by the triad oligo-anodontia, hypotricosis, hypo-anhydrosis (Christ-Siemens-Tourane syndrome). The incidence of HED is about 1/100,000. Mutation in the actodysplasin-A (EDA) and ectodysplasin-A receptor (EDAR) genes are responsible for X-linked and autosomal HED. The clinical features include sparse, fine hair, missing or conical-shaped teeth, decreased sweat and mucous glands, hypoplastic skin, and heat intolerance with exercise or increased ambient temperature. Complete or partial anodontia and malformation of teeth are the most frequent dental findings. Incisors and canines are often conical-shaped while primarily second molars, if present, are mostly affected by taurodontism. Treatment is supportive and includes protection from heat exposure, early prosthetic rehabilitation, skin, hair ear, nose and nail care, and genetic counseling for family planning. The diagnosis of HED in the neonatal and early infancy period may be difficult since sparse hair and absent teeth are normal finding at this age. In childhood the diagnosis is more easily made on the basis of history and clinical examination. Dental abnormalities are the most common complaint. Prosthetic rehabilitation has been recommended as an essential part of the management of HED because is important from functional, esthetic, and psychological standpoint. A team approach that includes input from a pediatric dentist, an orthodontist, a prosthodontist, and an oral and maxillofacial surgeon is necessary for a successful outcome. Conventional prosthodontic rehabilitation in young patient is often difficult because of the anatomical abnormalities of existing teeth and alveolar ridges. The conical shaped teeth and “knife-edge” alveolar ridges result in poor retention and instability of dentures. Moreover, denture must permit jaws expansion and a correct pattern of growth. Materials and Methods. Complete removable dentures were provided to allow for normal physiological development and a corrected masticatory function. Initial maxillary and mandibular impressions were made with smallest stock trays and irreversible hydrocolloid and then final impressions ware made with light-bodied polysulfide rubber base impression material. A base of autopolymerizing resin was constructed and a wax rim was added to the base. The patient’s vertical dimension of occlusion was established by assessing phonetic and esthetic criteria. Preliminary occlusal relations were recorded, and the mandibular cast was mounted on the articulator. Acrylic resin teeth specific for children dentures were selected and mounted. The dentures were tried in and, after proper adjustments, were inserted. The patients were monitored clinically every month to fit prostheses. Cephalometric radiographs were taken every 6 month with the prostheses in place in order to evaluate correct pattern of growth. Cephalometric measurements were realized and used to evaluate the effect of rehabilitation on craniofacial growth. Cephalometric measurements of sound patients were compared with ED patients. After two month expander screws (three-way screw in the upper denture and two-way the lower one)were inserted in each denture in order to permit the expansion of the denture and the jaws growth. Where conical teeth were present, composite crown were realized and luted to improve the esthetic and phonesis. In order to improve retention the placement of endosseous implants was carried out. TC 3D Accuitomo was performed and a resin model of mandibular bone of the patient was realized. At the age of 11 years two implants were inserted into anterior mandible in a child with anodontia. Despite a remarkable multi-dimensional atrophy of the mandibular alveolar process, the insertion of two tapered screw implants (SAMO Smiler, diameter 3.8, length 10 mm). After a submerged healing period of two-three month, the implants were exposed. Implants were connected with an expansion guide that permits mandibular growth and prosthetic retention. The amount of mandibular growth was also evaluate dusing the expansion guide. Results. Early oral rehabilitation improve oral function, phonesis and esthetic, reducing social impairment. Treated patients showed normal cephalometric measurement. Early rehabilitation is able to prevent the prognatissm of the mandibula . The number of teeth was significantly related to several changes in craniofacial morphology. Discussion. In the present study the 5,3% of ED patients showed hypodontia, the l’89,4% di oligodontia, and the 5,3% di anodontia. The cephalometric analysis supports that ED patients showed midface hypoplasia. ED groups showed an increased pogonion to nasion measurement than sound patients, indicative of class III tendency. The present study demonstrated that number of teeth was significantly correlated with deviation of cephalometric measurements from normality. Oligoanodontia is responsible for changing of cephalometric measuraments also on sagittal plane with a class III tendency. Maxillary jaw showed a retrused position related to the presence of hypodontia.

Studio analitico della cultura materiale fra VII e IX secolo d.C. nella Regione di Samarcanda (Uzbekistan): analisi morfo-tipologica, produzione e commercio della ceramica di Kafir Kala

Kafir Kala is a key-site to understand the historical dynamics of the Samarkand Region in the Early Middle Ages (5th - 8th centuries CE). The site is clearly associated with a Sogdian occupation, as both literature and archaeological research testify. But the chronological phase that follows the Sogdian period, as the Islamic occupation became stable, is still little known. Structures and finds (an hoard of 133 silver coins, in particular) clearly testify a new occupation of some parts of the citadel; and some rooms, dug in the northern side of it, present structures and materials connected with an Islamic activity. The study of material culture from these rooms, and from more ancient contexts, will help to understand the eventual continuity of traditions and the new productions. Besides the citadel, as a matter of fact, also some kilns have been dug, near the main site. Their material culture is very interesting because it represents an example of the typical Sogdian production (ceramics covered with white mica, and stamped). The work on the ceramic material has consisted in cataloguing and classifying all the diagnostics. Three main morphological classes have been individuated: cooking, coarse and table ware), and some other ones (lamps, ossuaries). A catalogue of the finds organized them in a typological system based on their morphology, function, fabric, and eventually decoration style. Crossing the stratigraphical data with information from this typological study, it has been possible to provide a chronological arrangement of the sites investigated by the italo-uzbek archaeological mission from 2001 to 2008.

L’instrumentum fittile inscriptum della colonia romana di Mutina e del suo territorio

Il presente lavoro è incentrato sulla raccolta e l’analisi dell’instrumentum fittile inscriptum – in particolare laterizi, dolia, lucerne, ceramica fine da mensa, anfore e tappi d’anfora - rinvenuto a Modena e nel suo territorio. L’attenzione è stata concentrata sul materiale bollato e, per quanto riguarda le anfore, anche sullo studio degli esemplari recanti tituli picti. Si è proceduto ad una raccolta di tutto il materiale edito, a cui si è aggiunto lo studio di un’ingente quantità di reperti provenienti da due recenti scavi suburbani: quello presso il Parco Novi Sad, che si segnala soprattutto per la ricchezza del materiale anforico, e quello di Viale Reiter, ove sono venuti alla luce numerosi scarti di cottura di lucerne a canale recanti le firme di alcuni dei più noti produttori di tali oggetti nel mondo romano. A ciascuna categoria di instrumentum è stato dedicato un capitolo, corredato di tabelle in cui è stato raccolto tutto il materiale considerato; inoltre, per i reperti del Parco Novi Sad e di Viale Reiter, è stato realizzato un catalogo corredato di riproduzioni grafiche e fotografiche. Per quanto concerne le iscrizioni dipinte, un capitolo è stato dedicato a quelle presenti sulle anforette adriatiche da pesce; quanto ai tituli picti su anfore di morfologia betica per il trasporto di salse di pesce è stato effettuato un confronto con esemplari rinvenuti in due scavi inediti a Parma, che presentano significative analogie col materiale modenese. Dall’analisi dell’instrumentum inscriptum di Mutina, pur consapevoli dei limiti insiti in una ricerca incentrata unicamente su tale tipo di materiale, è emersa un’immagine della colonia, tra la tarda età repubblicana ed il I sec. d.C., congruente con quella delineata dalle fonti letterarie, dall’epigrafia lapidaria e dai rinvenimenti archeologici, ossia di una città di notevole importanza e ricchezza.

Charakterisierung antiker Keramik und ihrer Herstellungstechniken mit mineralogischen Methoden am Beispiel Mayener Gebrauchskeramik

Mehr als hundert Jahre archäologischer Forschung haben gezeigt, dass in Mayen in römischer und mittelalterlicher Zeit eines der wichtigsten europäischen Produktionszentren für die Herstellung qualitätsvoller Gebrauchskeramik bestand. Im Rahmen dieser Studie wurden vier Befundkomplexe aus Töpfereisiedlungen vom 4. bis in das 14. Jahrhundert untersucht. Genauer handelt es sich um Keramik aus zwei spätantiken Brennanlagen des 4. Jahrhunderts im Bereich der Flur „Auf der Eich“ an den Straßen „Am Sonnenhang“ und „Frankenstraße“. Weiterhin konnte Material aus zwei Töpferofenfüllungen des 5. bis 9. Jahrhunderts analysiert werden, das 1975 auf dem Grundstück 55 an der „Siegfriedstraße“ in Brennanlagen entdeckt wurde. Hinzu kam Brenngut aus elf Töpferöfen des späten 8. bis 14. Jahrhunderts, welches in den so genannten „Burggärten“ der Genovevaburg von Mayen in den Jahren 1986/87 durch die archäologische Denkmalpflege in Koblenz geborgen wurde. Die mineralogischen Untersuchungen zur Charakterisierung der „Mayener Keramik“ wurden systematisch an den Keramikmaterialien aus diesen Fundstellen durchgeführt. Mittelalterliche Keramik aus Bornheim-Walberberg, Brühl-Eckdorf, Höhr-Grenzhausen, Langerwehe, Frechen, Brühl-Pingsdorf, Paffrath, Raeren, Ratingen-Breitscheid, Siegburg-Seehofstraße, Siegburg-Scherbenhügel, Fredelsloh und Brühl-Badorf konnte für diese Arbeit als Referenzmaterialien ebenfalls untersucht werden. Provenienzanalysen wurden an Keramikproben aus 27 Fundorten, die makroskopisch nach Mayener Ware aussehen, mit mineralogischen Methoden durchgeführt, um sie der Fundregion Mayen eindeutig zuordnen zu können.rnPhasenanalyse, chemische Analyse und thermische Analyse wurden an Keramik sowie Ton durchgeführt. Die Phasenanalyse wurde zur Bestimmung der mineralischen Zusammensetzung von Grundmasse und Magerungsmittel (Röntgendiffraktometrie (XRD), Polarisationsmikroskop, Mikro-Raman-Spektroskopie) verwendet. Die chemische Zusammensetzung wurde durch Röntgenfluoreszenzanalyse (RFA) ermittelt. Elektronenstrahlmikroanalyse (ESMA) und Laser-Massenspektrometrie mit induktiv gekoppeltem Plasma (LA-ICP-MS) wurden bei den Proben, bei denen weniger als 2g Material zur Verfügung standen, eingesetzt. Brennexperimente wurden am originalen Rohstoff der Keramik aus den „Burggärten“ der Genovevaburg durchgeführt. Gebrannter Ton wurde durch Röntgendiffraktometrie (XRD), Infrarotspektroskopie (IR) und Differential-Thermoanalyse (DTA) analysiert. rnAnhand der Messergebnisse lässt sich die Mayener Keramik aus den vier Fundplätzen in zwei Typen zusammenzufassen: der mit Feldspat-reichem Sand gemagerte römische Typ und der mit Quarz-reichem Sand gemagerte mittelalterliche Typ. Die Änderung des Magerungsmittels von Feldspat- zu Quarzsand weist eine technische Entwicklung zu höheren Brenntemperaturen von der Römerzeit bis in das Mittelalter nach. Nach der Untersuchung und dem Vergleich mit den Referenzkeramikgruppen ist festzustellen, dass durch multivariate Statistikanalysen der chemischen Komponenten die Charakterisierung der Keramik und eine Differenzierung zwischen den Keramikgruppen gelingt. Diese Erkenntnisse bildeten die Basis für Provenienzanalysen. 16 Fundorte können durch Provenienzanalyse sicher als Exportregionen der Mayener Ware festgestellt werden. Gemäß den Brennexperimenten lassen sich die chemischen Reaktionen während des Brandprozesses nachvollziehen. Zwei Methoden wurden mittels Röntgendiffraktometrie (XRD) und Differential-Thermoanalyse (DTA) zur Bestimmung der Brenntemperaturen der Keramik modelliert. Die Töpferöfen der „Burggärten“ können nach der Brenntemperatur in zwei Typen zusammengefasst werden: solche mit einer Brenntemperatur unter 1050°C und solche mit einer Brenntemperatur über 1050°C.rn

Zur Darstellung und Interpretation archäologischer und geowissenschaftlicher Untersuchungen anhand einer Auswahl römischer Gebrauchskeramik aus dem Limeskastell Saalburg

Die vorliegende Arbeit gliedert sich in drei Kapitel. Das erste Kapitel umfasst dabei die Darstellung von Methoden, die zum gegenwärtigen Zeitpunkt unter anderem in der provinzialrömischen Archäologie zur Untersuchung von Gefäßkeramik üblich sind, wobei die Einzelergebnisse des im Rahmen dieser Arbeit untersuchten gebrauchskeramischen Materials (Randfragmente) der Saalburg (bei Bad Homburg) am Ende des Kapitels zusammengefasst werden. Im zweiten Kapitel werden anhand des gleichen Materials einige naturwissenschaftliche Methoden dargestellt, die zur Materialanalyse sowohl in den Geowissenschaften (Materialwissenschaft), als auch in der Archäometrie häufig Anwendung finden und deren Ergebnisse am Ende des Kapitels zusammengefasst. In einer Gesamtbetrachtung (drittes Kapitel) werden schließlich diese hinsichtlich ihrer Aussagekraft in archäologischem Kontext evaluiert. Neben der im Anhang festgehaltenen Original-dokumentation der Dünnschliff-Untersuchungen (Ramanspektroskopie, „RS“), werden im Abbildungsteil die Kopien der Originaldaten aus der Röntgendiffraktometrie („XRD“) und der Röntgenfluoreszenzanalyse („RFA“, chemische Analyse), Abbildungen einiger Festkörper, als auch Zeichnungen, Photos und Dünnschliffe der Randfragmente aufgeführt. Während die Darstellung der angewandten Methoden einer Verständniserleichterung vor allem der komplexen chemisch-physikalischen Zusammenhänge dienen soll - nicht zuletzt auch, um die künftige Methodenwahl zu optimieren - soll mittels der Evaluation, vor allem für die Keramikforschung, die Entwicklung neuer Forschungsmethoden unterstützt werden. Aus dem Vergleich der Ergebnisse beider Kapitel erhebt sich nicht allein für die Keramikforschung die Frage, inwieweit die Anwendungen bestimmter Untersuchungen überhaupt sinnvoll sind, wenn sie nicht nur der Bestätigung dienen sollen, sondern welche Konsequenzen daraus auch für die Untersuchung anderer historisch-kultureller Materialgruppen resultieren könnten.

Design, conduct, and analysis of a multicenter, pharmacogenomic, biomarker study in matched patients with severe sepsis treated with or without drotrecogin Alfa (activated)

A genomic biomarker identifying patients likely to benefit from drotrecogin alfa (activated) (DAA) may be clinically useful as a companion diagnostic. This trial was designed to validate biomarkers (improved response polymorphisms (IRPs)). Each IRP (A and B) contains two single nucleotide polymorphisms that were associated with a differential DAA treatment effect.

Ceramics, Trade, Provenience and Geology: Cyprus in the Late Bronze Age

The island of Cyprus was a major producer of copper and stood at the heart of east Mediterranean trade networks during the Late Bronze Age. It may also have been the source of the Red Lustrous Wheelmade Ware that has been found in mortuary contexts in Egypt and the Levant, and in Hittite temple assemblages in Anatolia. Neutron Activation Analysis (NAA) has enabled the source area of this special ceramic to be located in a geologically highly localised and geochemically distinctive area of western Cyprus. This discovery offers a new perspective on the spatial organisation of Cypriot economies in the production and exchange of elite goods around the eastern Mediterranean at this time.

Anti-inflammatory and immunosuppressive drugs and reproduction

Rheumatic diseases in women of childbearing years may necessitate drug treatment during a pregnancy, to control maternal disease activity and to ensure a successful pregnancy outcome. This survey is based on a consensus workshop of international experts discussing effects of anti-inflammatory, immunosuppressive and biological drugs during pregnancy and lactation. In addition, effects of these drugs on male and female fertility and possible long-term effects on infants exposed to drugs antenatally are discussed where data were available. Recommendations for drug treatment during pregnancy and lactation are given.
