Published: November 2020

Background: Reconstruction of complex critical-size defects (CSD) in craniofacial region is a major challenge, and the soft tissue regeneration is crucial in determining the therapeutic outcome of craniofacial CSD. Stem cells from apical papilla (SCAP) are neural crest-derived mesenchymal stem cells (MSCs) which are homologous to craniofacial tissue, and represent a promising source for craniofacial tissue regeneration. Exosomes, which contained compound bioactive contents, are the key factors of stem cell paracrine action. However, the roles of exosomes derived from SCAP (SCAP-Exo) in tissue regeneration are not fully understood. Here, we explored the effects and underlying mechanisms of SCAP-Exo on CSD in maxillofacial soft tissue. Methods: SCAP-Exo were isolated and identified by transmission electron microscopy and nanoparticle tracking analysis. The effects of SCAP-Exo on wound healing and vascularisation were detected by measuring wound area, histological and immunofluorescence analysis in the palate gingiva CSD of mice. Real-time live cell imaging and functional assays were used to assess the effects of SCAP-Exo on the biological functions of endothelial cells (ECs). Furthermore, the molecular mechanisms of SCAP-Exo mediated ECs angiogenesis in vitro was tested by immunofluorescence staining, Western blot and Pull-Down assays. Finally, in vivo experiments were carried out to verify whether SCAP-Exo could affect the vascularisation and wound healing through Cdc42. Results: We showed that SCAP-Exo promoted tissue regeneration of palatal gingiva CSD by enhancing vascularisation in the early phase in vivo , and also indicated SCAP-Exo improved the angiogenic capacity of endothelial cells (ECs) in vitro . Mechanistically, SCAP-Exo elevated cell migration by improving cytoskeletal reorganization of ECs via cell division cycle 42 (Cdc42) signalling. Furthermore, we revealed that SCAP-Exo transferred Cdc42 into the cytoplasm of ECs, and the Cdc42 protein could be reused directly by the recipient ECs, which resulted in the activation of Cdc42 dependent filopodia formation and elevation of cell migration of ECs. Conclusion: This study demonstrated that SCAP-Exo had a superior effect on angiogenesis and effectively promoted craniofacial soft tissue regeneration. These data provide a new option for SCAP-Exo to be used as a cell-free approach to optimize tissue regeneration in the clinic.

Published: November 2020

Background: The non-HDL-cholesterol to HDL-cholesterol (NHDLC/HDLC) ratio is closely related to a variety of dyslipidemia-related diseases. This study examined the relationship between the NHDLC/HDLC ratio and non-alcoholic fatty liver (NAFLD) in children and adolescents.Methods: This cross-sectional survey included a total of 7,759 eligible Chinese children and adolescents (5,692 boys and 2,067 girls) who received routine medical examinations. The anthropometric and laboratory data of the subjects were collected. NAFLD was diagnosed by liver ultrasonography. Binary logistic regression analysis was performed on the NHDLC/HDLC ratio, NHDLC, HDLC and NAFLD. Receiver operating characteristic (ROC) curve analysis was used to compare the diagnostic significance of the above parameters for NAFLD.Results: The total prevalence of NAFLD was 4.36%, and the prevalence in boys was higher than that in girls (5.61% vs. 1.9%, P < 0.001). The prevalence of NAFLD was positively correlated with the NHDLC/HDLC ratio (P < 0.001). The binary logistic regression analysis demonstrated that the OR was 8.61 (95% CI, 5.90-12.57, P < 0.001) in tertile 3 (highest NHDLC/HDLC ratio) compared with tertile 1 (lowest NHDLC/HDLC ratio). After adjustment for age, sex, body mass index (BMI), alanine aminotransferase (ALT), uric acid (UA), total bilirubin (TB), fasting plasma glucose (FPG) and Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), the OR for tertile 3 (OR=1.83, 95% CI, 1.04-3.22, P = 0.035) was still significantly higher than that of tertile 1. The area under the curve (AUC) of the NHDLC/HDLC ratio of boys was 0.787, which was significantly greater than NHDLC and HDLC (0.719 and 0.726, P < 0.001). For girls, the AUC of the NHDLC/HDLC ratio was 0.763, which was also significantly greater than NHDLC (0.661, P < 0.001). The cutoff point of the NHDLC/HDLC ratio was 2.475 in boys and 2.695 in girls. In addition, the AUC of the NHDLC/HDLC ratio was 0.761 in subjects with normal ALT levels (ALT ≤ 40 U/L), which was significantly higher than NHDLC (0.680, P < 0.001) and HDLC (0.724, P = 0.007). For subjects with elevated ALT levels (ALT > 40 U/L), the AUC of the NHDLC/HDLC ratio (0.746) was also significantly greater than NHDLC (0.646, P < 0.001)Conclusions: The NHDLC/HDLC ratio was positively correlated with NAFLD in Chinese children and adolescents. It may serve as an effective indicator to help identify NAFLD in children and adolescents.

Published: November 2020

Background: The role of bone tissue engineering is to regenerate tissue using biomaterials and stem cell based approaches. Combination of two or more cell types is one of the strategies to promote bone formation. Endothelial progenitor cells (EPCs) may enhance the osteogenic properties of mesenchymal stem cells (MSCs) and promote bone healing, this study aimed to investigate the possible mechanisms of EPCs on promoting osteogenic differentiation of MSCs. Methods: MSCs and EPCs were isolated and co-cultured in Transwell chambers, the effects of EPCs on the regulation of MSC biological properties was investigated. Real-time PCR array and western blotting were performed to explore possible signaling pathways involved in osteogenesis. The expression of osteogenesis markers and calcium nodule formation was quantified by qRT-PCR, western blotting and Alizarin Red staining. Results: Results showed that MSCs exhibited greater alkaline phosphatase (ALP) activity and increased calcium mineral deposition significantly when co-cultured with EPCs. The mitogen-activated protein kinase (MAPK) signaling pathway was involved in this process. p38 gene expression and p38 protein phosphorylation levels showed significant up-regulation in co-cultured MSCs. Silencing expression of p38 in co-cultured MSCs reduced osteogenic gene expression, protein synthesis, ALP activity and calcium nodule formation. Conclusions: These data suggest paracrine signaling from EPCs influence the biological function and promote MSCs osteogenic differentiation. Activation of the p38MAPK pathway may be the key to enhancing MSCs osteogenic differentiation via indirect interactions with EPCs.

Authors: Mishra Shruti , S. Kishore Kumar , Nag Dipanwita
Published: November 2020

Background: There are not many studies conducted in India to compare cell block preparation methods with reagents and materials that are readily available in all laboratories. This study aimed to standardize and compare two simple cell block techniques, which can be done in low resource settings too. In the study, 35 cases of thyroid, lymph node, and breast were collected for both FNA and cell block preparation for six months.

Materials and Methods: There were separate passes given for both methods. A total of seventy cell blocks made using formalin and agar methods of preparation.

Results: We compared both the methods on technical and morphological levels. The formalin method was overall easy to perform and was yielding good morphological results in 98% cases, the only drawback being cell loss during handling and processing. While in the agar method, there was almost no cell loss, but it was more technically difficult and yielded poorer morphological results. A scoring system was made for cellularity: no cells = 0, hypo-cellular = 1+, hypo-cellular with tissue fragments = 2+, cellular = 3+.18 A score of 2+ and 3+ was scored by 31/35 formalin blocks and 28/35 agar blocks.

Conclusions: The sensitivity of both formalin and agar methods are almost comparable. However, the procedure of the formalin method is far more straightforward and user friendly. Moreover, it also provides a better architectural picture than the agar method.
Is Aerated Soft Drink and Packaged Juice Consumption an Independent Risk Factor to Cause Non-Alcoholic Fatty Liver Disease
Authors: Kunal Kukreja , Prateek Kinra , MS Tevatia
Published: November 2020

BACKGROUND:

There has been an increase in consumption of aerated sweetened soft drinks and packaged juices high in carbohydrates/fructose by humans across the globe. There have been various studies with contradictory inferences of association of chronic sweetened soft drink (rich in high fructose corn syrup) intake and NAFLD. This study was undertaken with the aim to determine the quantity, frequency, duration and type of sweet soft drinks /packaged fruit juices consumption in patients with NAFLD as compared to that in control population. Other objectives included assessment of the independent role of sweetened soft drinks as a risk factor for NAFLD in the absence of metabolic syndrome and to correlate the level of steatosis (objectively graded by ultrasonography) with the amount of intake of soft drinks in patients of NAFLD.

METHOD :

50 patients of NAFLD as diagnosed clinically and by ultrasonography were identified and compared with 50 age matched control population reporting to the hospital with ailments other than NAFLD. The presence or absence of metabolic syndrome was noted in all the patients. The history of soft drink intake was obtained from the patient under following heads: a) quantity consumed, b) type of soft drink/packaged juice consumed, c) period of ingestion and d) frequency of consumption.

RESULT :

The average monthly consumption, duration of consumption and the mean total sugar consumption of sweetened soft drinks / packaged juices were significantly higher in patients with NAFLD versus those in the control group (p=0.0002; <0.0001; p=0.002 respectively). The quantity and chronicity of intake correlated well with the grade of NAFLD. As the average monthly consumption and mean sugar consumption increased the grade of fatty liver on USG also increased (p= 0.004). A total of 11 patients out of all the 100 patients (study and control groups combined) had a daily intake of 150-300ml of SSD for a period ranging from 5 to 20 years. Two of these had grade I NAFLD whereas 9 had grade II-III NAFLD. Five of these 11 patients had a daily intake of 250ml or greater. All these 5 patients had grade II-III NAFLD documented on ultrasound findings.

Conclusion

The consumption of sweetened soft drinks and packaged juice is on the rise in India. The intake of these drinks is significantly higher in patients with NAFLD.

Published: November 2020

Lymphoepithelial cysts are benign, slowly growing unilocular or multilocular lesions that appear in the head and neck region. They are also called branchial cysts and occur due to lymphocyte induced cystic ductular dilatation. The confirmatory diagnosis is always made on histopathological examination after resection.

A 29 years old female patient presented to ENT department, Pt B. D. Sharma PGIMS, Rohtak with a soft to firm, non-tender, swelling in the submandibular region since 2 -3 days and was referred to Department of Pathology for FNAC on which a differential diagnosis of infected epidermoid cyst or squamous cell carcinoma was made and excision biopsy for confirmation and categorization was advised. The swelling was then excised and sent for histopathological examination and a final diagnosis of Lymphoepithelial cyst was made. The confirmatory diagnosis is always made postoperatively by histopathological examination. The treatment of a lymphoepithelial cyst is the surgical approach, which includes complete enucleation of the cyst. This is a case report of a lymphoepithelial cyst diagnosed on histopathology specimen for which differential of Infected cyst or Squamous cell carcinoma was given. The authors intend to highlight the importance of early histopathological diagnosis of Benign LEC as it has been reported to undergo malignant transformation

Authors: Khari Pooja , Srivastava Sphruti , Mullick Shalini
Published: November 2020

Background: Cytologic examination of specimens obtained from the respiratory tract is the primary and frequently used diagnostic technique in patients with respiratory symptoms or in those presenting with a pulmonary abnormality. Lung carcinoma is the leading cause of mortality in India. Hence, early diagnosis and effective treatment are keys to prolong the survival of lung cancer patients.

 

Methods: 100 consecutive samples were taken which included 66 samples of bronchial wash, 27 samples of brush and 7 samples of bronchoalveolar lavage. These were viewed independently by two pathologists to study the ease of applicability, reproducibility and role of Papanicolaou Society of Cytopathology classification for pulmonary specimens.

 

Result: The classification and terminology scheme recommend a six-tiered system comprising of non-diagnostic, negative, atypical, neoplastic (benign and neoplasms of low malignant potential), suspicious and positive for malignancy. In our study 43% were non-diagnostic, 33% were negative, 10% were atypical, 6% were suspicious for malignancy and 8% were malignant.

 

Conclusion: This classification system of respiratory cytology is easy to apply and interpret with minimal inter-observer variation. Standardized classification and terminology system provide a framework for consistent inter-intra departmental and inter institutional communication of diagnostic, prognostic and management information needed for consistent and optimal patient care.

Authors: Punnoose Asha Peedikayil , Ramakrishnan Deepti , Thomas Kripa Susan
Published: November 2020

Background: Nipple sparing mastectomy is widely used for both treatment and risk reduction of breast cancer. Terminal duct lobular units (TDLU) are considered as the basic reacting unit in all neoplastic lesions arising from the breast. TDLU is the basic anatomic unit of breast parenchyma, studies revealed that it also exists in the nipple whose frequency is not widely researched. Our objective is to study the frequency of TDLUs in nipple along with its location, number and association with age and laterality of breast.

 

Methods: The descriptive study involved entire submission of nipples from 191 consecutive therapeutic mastectomy specimens from a reputed cancer institute in India between January 2015 and June 2016. The nipple is divided into two parts, nipple papilla and nipple base and presence of TDLU were recorded separately.

 

Result:  From the specimens submitted, 38% were observed to have TDLU in the nipple. While 45.2% were in the papillae and 26% in the base the remaining 28.8% were in both the papillae and base with maximum number of TDLU counted at 5 and mean age of subjects at 53.56 years, 57.5% from the left and 42.4% from the right breast respectively. There was no significant association between age (p= 0.59), laterality of breast (p = 0.37) with presence of TDLU whereas a significant negative linear correlation observed between age and number of TDLUs (r =-0.237, p=0.043).

 

Conclusion: Nipples show a high frequency of TDLU and is observed more in papilla than in the base.

Published: November 2020

Natural graphite, a polygenic mineral, is a product of regional, contact, impact metamorphism, and magmatic or fluid deposition. In fluid-deposited graphite, aqueous C-O-H systems play a special role in determining the characteristics of hydrothermal products by shifting the chemical equilibrium. From this viewpoint, the recently discovered carboniferous mineralization in the Baikal hydrothermalites has attracted increasing interest with regard to graphite crystallization under the influence of low-pressure low-temperature (LPLT) carboniferous H2O-rich fluids. Herein, we studied graphite mineralization in the geyserites and travertines of the Baikal geyserite paleovalley (Eastern Siberia, Russia) by applying a multitude of mineralogical studies. Optical, scanning, transmission electron, and atomic force microscopy, energy-dispersive spectroscopy, Raman spectroscopy, and carbon isotopic composition analyses of graphite, carbonate carbon, and oxygen in both the hydrothermalites and host rocks were conducted. The obtained results revealed several peculiar features regarding the graphite in geyserites and travertines. We found that Baikal graphite, earlier predicted to be a product of hydrothermalites, generally occurs as a relict graphite of the host metamorphic rocks with partial in situ redeposition. The newly formed LPLT fluid-deposited graphite is characterized by micrometer- and submicrometer-sized idiomorphic crystallites overgrown on the relict metamorphic graphite seeds and between calcite sinter zones during the last stage of travertine formation. The results present additional valuable data for understanding the mechanism, range of the formation conditions, and typomorphism of fluid-deposited graphite with probable crystallization from carbon solution in the C-O-H system at LPLT conditions.

For simulations where the forward and the inverse directions have
a physics meaning, invertible neural networks are especially useful.
A conditional INN can invert a detector simulation in terms of
high-level observables, specifically for ZW production at the
LHC. It allows for a per-event statistical interpretation. Next, we
allow for a variable number of QCD jets. We unfold detector effects
and QCD radiation to a pre-defined hard process, again with a
per-event probabilistic interpretation over parton-level phase
space.
Autoidentificaciones étnicas de jóvenes de segunda generación de origen mexicano en California
Authors: Narváez Jiménez María del Rosario
Published: November 2020

El objetivo de este artículo es explorar las autoidentificaciones étnicas de los jóvenes de segunda generación de origen mexicano. Para ello se toman tres elementos del contexto sociopolítico estadounidense que se encuentra en relación con sus autoidentificaciones, estas son: el propio modelo identitario estadounidense, el imaginario social sobre el mexicano y las categorías censales sobre la etnicidad hispana/latina y la raza. El enfoque biográfico, concretamente la perspectiva etnosociológica de Daniel Bertaux a través de los relatos de vida, ha sido la técnica empleada. La investigación se llevó a cabo durante 2016, en el sur de California donde se entrevistó a 51 jóvenes. Los relatos constatan que algunas de las categorías institucionales llevan a que sean parte de las autoidentificaciones de los informantes, o estos se adjudican muchas de las características fenotípicas y/o raciales que se les atribuyen a dichas categorías. Como limitación se encuentra la imposibilidad de incluir otros relatos.

Arqueologia e Modernidade: uma revisitação pessoal e breve de alguns aspetos da obra homónima de Julian Thomas de 2004
Authors: Jorge Vítor Oliveira
Published: November 2020

In 2004, Julian Thomas (University of Manchester), published an important work: “Archaeology and Modernity” in which he sought to show that archeology is a science, a discipline and an activity that could only have appeared in our Modernity, that is, in the period that opened with the European seventeenth century. After 16 years, we can take stock of it and certainly propose some new topics, not yet covered in that book, either at the option of the author, or because of the development of our knowledge. This paper intends to be a short contribution in that sense, although assuming its personal and very partial nature. If in 2004 the book’s final conclusions and proposals should be discussed, the time that has elapsed since then has obviously changed the picture of the issues

Published: November 2020

The study of the historical period that followed the Western Roman Empire evidenced social and economic transformations that had great expression in the urban fabric of cities. In this sense, we propose a synthesis of the economic dynamics of Bracara in Late Antiquity, a period marked by the affirmation of new urban, social, political and religious realities, as well as by the gradual abandonment of constraints and imperatives that marked the previous city. For that, we will use data from archaeological interventions carried out in Braga, which document how transformations occurred between 3rd-8th centuries, a period delimited by the elevation of the city to capital of Gallaecia and Muslim invasions, which mark the end of trade at Mediterranean level.

Published: November 2020

The Lafões territory was subjected to an intense human occupation since Protohistoric times, focused on the exploitatian of its mineral wealth. In the Early Middle Ages it was a kea-area where written and archaeological evidence shows its importance for local Christian populations and to recently-established Galician-Asturian lords. After almost a century of Christian rule, the Lafões region was temporarily back in Muslim hands, only to be finally regained when Viseu and Coimbra were reconquered (in 1058 and 1064, respectively). At that time, the fort that has now been revealed archaeologically on Monte da Senhora do Castelo (Mount of Our Lady of the Castle) in Vouzela would have already a relevant strategic functions

This study intends to present the identified context and, later integrate it into the spatiality of the city of Lisbon compiling other funerary contexts of medieval chronology intervened. Therefore, it is intended to present a state of the question regarding these contexts given the importance of the collaboration of various elements
Arqueologia Moderna em Portugal: algumas reflexões críticas em torno da quantificação de conjuntos cerâmicos e suas inferências históricas e antropológicas
Authors: Silva Rodrigo Banha da , Bargão André , Ferreira Sara da Cruz
Published: November 2020

Early Modern Archaeology is becoming a nodal área of study in Portuguese Archaeology, due to the increasing numbers of excavations, as in terms of publication of sites, contexts and material culture. Nevertheless, this progress doesn´t display a refined preoccupation on methodology and theoretical frameworks. The authors address this issue focusing its interest on artefact assemblages and categories quantification and its narrow relation to context functional profile, noteworthy two of the fundamental basis allowing historical and anthropological inferences

Era-Arqueologia excavated in 2004 and 2009 two significant buildings in Bairro Alto quarter in Lisbon, due to urban rehabilitation projects. With approximate 17th century chronologies, they display very distinctive socioeconomic profiles: one, St. Peter’s and St. Paul’s Honourable Pontifical College (commonly known as the “Little English Convent”), and was devoted to catholic teaching to the British community living in Lisbon during Early Modern Age; the other, a noble mansion belonging to Mesquitela Earls. Despite archaeological limitations of contextual data, they display some contrast between the religious context and the noble one, allowing some archaeological inference on social significance of pipe presence in Early Modern Age contexts from Lisbon

Published: November 2020

In 2018 an archaeological intervention in Rua do Terreiro do Trigo was undertaken by municipal determination for the installation of recycling containers in Lisbon. Amongst the sherds recovered it’s possible to identify a great amount of European kaolin smoking pipes fragments dated from the 17th to the 18th centuries and also a set of unusual black and grey earthenware chibouks of unknown origin. Therefore, this approach seeks to report the smoking pipe assemblage recovered in Rua do Terreiro do Trigo and to discuss the study of smoking devices in the Portuguese early modern contexts

The authorities of the Republic of Cape Verde and the former Portuguese institute of heritage (IPPC) cooperate to do an archaeological excavation between 1989 and 1993 in the ruins of the Cathedral of “Cidade Velha”, the former main religious spot of the archipelago, under the direction of one of the authors (C.A. – Amaro, 2013). The work revealed several contexts connected with reformations of the religious temple dating from late 17th and 18th century, providing an insight on material culture of the colonial period in Cape Verde Archipelago. Clay tobacco pipe sherds were identified, displaying some data related to commercial links between the Portuguese Empire and other European spaces, as well as suggestive of the frequency of tobacco consumption in Cape Verde at the time.
Algumas considerações sobre espólio não cerâmico recuperado no Largo de Jesus (Lisboa)
Authors: Boavida Carlos
Published: November 2020

The construction of an underground car park at Largo de Jesus, in Lisbon, led to an archaeological intervention in 2005. That space corresponds to the old churchyard of the Jesus’ Church, the Mercês’ current parish seat. In addition to other remains, the foundations of the staircase leading to the church were identified, as well as several wall structures. Some of those seem to be prior to the 1755 earthquake and related to an area of warehouses that could have belonged to the Mendia palace, on the west side of the square, completely remodeled after the earthquake. The intervention also made it possible to verify that different rebuilding works on that place eliminated, progressively, the previous spatial realities, affected it in all the stratigraphic contexts detected, compromising and hindering their reading. There are numerous remains of everyday material that were found in those realities, with special emphasis on ceramic containers; however, the objective of this work is to present some of the non-ceramic artifacts recovered there.

Amongst them, numerous glass adornments, which include rings, bracelets and a significant collection of beads, collected in cesspits and graves. The beads present an accentuated polymorphism and chromatism, being attributed to the late 16th century and, mainly, to the following one. Their origins can be traced to Italy, Netherlands and, perhaps, England, which denounces, as happens with the remaining testimonies collected, a wealthy society, with exquisite taste, able to access international trading routes to provide not only for the high demands of fashion but also the maintenance of their social status

«Não passa por teu o que me pertence». Marcas de individualização associadas a faianças do Convento de Nossa Senhora de Aracoeli, Alcácer do Sal
Authors: Parreira Catarina , Fragoso Íris , Sousa , Miguel Martins de
Published: November 2020

Founded in 1573 by Rui Salema and Catarina Sotto Mayor Salema, the Convento de Nossa Senhora de Aracoeli was located in the old house of the Order of Santiago. Extinct in 1874 it was in ruins by the renovation undertaken for the building of Pousada D. Afonso II. Following the excavation, carried out between 1993 and 1997, expressive archaeological remains were identified, including a diverse collection of Portuguese faience. The issue that is presented relates to incised motifs which the study of the faience, collected in two sites from the conventual fence, reveled. Therefore, this study uses a selected assemblage as a socioeconomic indicator, leading it to be associated with the conventual, perhaps prophylactic, daily routine of Alcácer do Sal

Published: November 2020

The Coastal Geopark of Viana do Castelo occupies 320 km2 of the Portuguese NW. It includes coastal and mountainous areas and distinct sociocultural and territorial contexts, and a unique and diverse set of archaeological sites. The present work intends to show how some of these sites have leisure and educational potential on their own, or when articulated with other geological resources. Some actions are highlighted and proposed for the valorisation of the archaeological heritage located inside the limits of the Geopark, evidencing what has already been done to know and protect this important (but fragile) set of past traces

Authors: Silva Hugo , Oliveira Filipe
Published: November 2020

Following archaeological works (surveys and monitoring), executed during the requalification of a building outside the walls of Óbidos Castle, in Rua da Biquinha, 64, preserved archaeological contexts were identified that depict the occupation of the site between the late 15th / beginning of the 16th century until the 20th century. The works allowed for the identification of a set of four ovens located inside the building. These combustion structures, of sub-circular plan were probably used for pottery production. They were excavated into the bedrock and a small collection of materials of Medieval/Modern chronology were found associated with them

The archaeological site of Silha do Alferes was discovered in 1984. Illegal excavations were made by metal detector owners and in that same year the Museum of Seixal recorded the site and recovered the material culture left behind. The collection is well preserved with several complete objects such as bowls, plates, cups, lids, and braziers among others. This is the typical collection of a domestic context. The typology of the artefacts corresponds to a first half of the 16th century context formation. This paper aims to acknowledge this site debating its importance in the study of Seixal are

Published: November 2020

The archaeological site of Alto da Vigia is located in the mouth of the river of Colares, in the municipality of Sintra, and traces of a Roman sanctuary, an Islamic ribat and a coastal surveillance shelter have been identified. We now present some materialities from the latter occupation, dating back from the beginning of the 16th to the 19th century, a long period during which the site had an important role in the defence and surveillance of the coast. The research of old cartography and archive documentation, complemented with archaeological survey, allowed the identification of new data related to coastal surveillance in the northern region of the Tagus River between the 16th and 19th centuries

Published: November 2020

The necropolis found in Rua do Recolhimento 7/9, Castle of São Jorge, Lisbon, Portugal, corresponds to the military hospital cemetery, located nearby, in activity from the 16th to the 18th centuries. During the archaeological excavation both individual, multiple, and mass graves as well as ossuaries were identified. Space management becomes evident on several burials, mainly with overlap of other burials that end cutting the oldest ones, skeletons in supine, ventral and lateral position (and against walls), not always in conformity with the canonical Christian rules. This post-medieval necropolis presents an array of funerary practices as a reflection of the Lisbon modern society, transmitting social, cultural and religious worries, becoming a public health issue due to the amount of bodies deposit in such a small space and in a short time
