Caracterización socio-económica de la cría de bovinos en la agricultura familiar del Alto Egipto
Authors: Molina-Flores B. , Velasco G. , Camacho M.E. , Martínez M.A. , Delgado J.V.
Published: March 2019

El Egipto actual es una entidad compleja, que enfrenta una lucha contra el crecimiento de la población y la pobreza en el camino hacia un desarrollo humano equitativo. Esto es particularmente cierto en el Alto Egipto, donde más de la mitad de la población rural se considera en situación de pobreza, siendo la agricultura familiar, y en particular la cría de bovinos, una de sus principales fuentes de ingresos. Para identificar los factores socio-económicos que influyen en los sistemas tradicionales de agricultura familiar dedicados a la cría de bovinos, así como evaluar los conocimientos, aptitudes y prácticas de los productores pecuarios del Alto Egipto, se diseñó un estudio basado en entrevistas individuales y colectivas realizadas en hogares seleccionados de las gobernaciones de Minya, Assiut, Sohag, Quena y Luxor. Los resultados muestran como la cría de bovinos en esta región se ve significativamente obstaculizada por el limitado acceso a la tierra, el alto costo y escasa disponibilidad de insumos básicos, la marcada estacionalidad de la productividad animal, unos servicios de extensión pecuaria insuficiente y la dificultad para acceder a créditos y préstamos. Además, las estrategias y programas de mejora genética nacionales han descuidado las razas bovinas autóctonas (Baladi), a pesar de ser consideradas por los productores más adaptadas y resistentes a las severas condiciones locales. La comprensión de estos factores es esencial para la formulación e implementación de estrategias de intervención destinadas a mejorar la calidad de vida de estas comunidades rurales, así como preservar y gestionar los recursos zoogenéticos bovinos que explotan.
FINANCIAL VULNERABILITY AND INCOME INEQUALITY: NEW EVIDENCE FROM OECD COUNTRIES
Authors: Apergis Nicholas
Published: March 2019

This study explores, for the first time, how financial vulnerability affects incomeinequality across OECD countries, from 1990 to 2015. The empirics use a new financialvulnerability index constructed by Adrian and Duarte (2016). Through the methodologyof their modeling approach, panel GARCH and GMM methods, the findings indicatethat financial vulnerability exerts a negative impact on income equality conditions.The results survive certain definitions of income inequality and corruption, whilethey highlight the importance of financial stability conditions, with potential furtherrepercussions to the real economy.
THE IMPACTS OF GOVERNMENT R&D EXPENDITURE ON INNOVATION IN CHINESE PROVINCES: WHAT’S THE ROLE OF CORRUPTION
Authors: Zhou Xiao-Bo , Wei Wei , Jang Chyi-Lu , Chang Chun-Ping
Published: March 2019

This study aims to investigate the moderating role of corruption on the effect of government R&D expenditure on enterprise innovation in China, using the annually data over the period 2002-2013 in a panel of 30 provinces. A dynamic panel system GMM model was used to explore the relationship among government R&D expenditure, corruption, and innovation. Our finding shows that though government R&D expenditure has no significant effects on patent applications, it does exhibit significantly positive effects on patents granted. However, when considering official corruption, the interaction term of government R&D expenditure and corruption has a statistically significantly positive effect on patent applications and patents granted, with corruption presenting significantly positive effects on the ratio of the number of patents granted to patent applications. It demonstrates that corruption is still a shortcut for overcoming red tapes and administrative intervention, especially in an economy in transition with lower institution quality and anti-corruption.
The Cheatwood Place (41RR181), a Midden Mound along Little Mustang Creek, Red River County, Texas
Authors: Gaither Steve , Perttula Timothy K. , Cheatwood Gary
Published: March 2019

The Cheatwood Place is a multi-component midden mound located on an upland projection at the confluence of Christopher Branch and Little Mustang Creek, about 1.5 kilometers north of the Sulphur River. The site has thick midden deposits with excellent fauna! and shell preservation, and promises to contribute important information on several periods of Sulphur River prehistory. The archaeological record in this part of the Sulphur River basin is not well known at present.

Investigations at the Cheatwood Place site have been limited to surface collections, and the excavation by Cheatwood of a single 1 x 1 meter test unit in the midden mound. Vertical provenience was not noted in the test unit, the matrix of which was screened through 1/4 inch mesh, except that the midden was approximately 60 to 90 cm in thickness with artifacts throughout the deposit.
A Perspective on Arkansas Basin and Ozark Highland Prehistory
Authors: Rogers J. Daniel
Published: March 2019

It is, from time to time, valuable to reassess and perhaps shed new light on long-held perspectives. In "The 'Northern Caddoan Area' was not Caddoan," Frank Schambach provides a provocative reinterpretation of the archaeology of the Arkansas Basin and Ozark Highland regions of Oklahoma, Arkansas, and Missouri. While certain comments in this paper have merit and deserve deeper consideration, the central theme and supporting arguments are severely flawed, both from conceptual and data points of view.

Schambach's central argument is that there were no Caddoans in the Arkansas Basin and Ozark Highlands north of Spiro. To make this point he asserts that the only Caddoan site north of the Ouachita Mountains is the Brown Mound group at Spiro. All the other sites in the region, including the Craig Mound group at Spiro, are not Caddoan, but are instead a currently undefined Mississippian manifestation. Schambach's scenario goes. something like this: Mississippians moved up the Arkansas River valley in the early,Mississippian Period (presumably in the Harlan Phase, A.O. 850-1250), through western Arkansas to eastern Oklahoma where they displaced the Caddoans living at the Brown Mound group. The Caddoans moved back south to the Ouachita Mountains. The Mississippians, including "people of the Plum Bayou culture ... the Spiro phase [A.O. 1250-1450]" then built Craig Mound at Spiro while possibly operating a trade system "to supply buffalo meat arid hides to the rapidly growing and increasingly protein poor and clothing poor Mississippian populations. . .. " to the east. Later, the Mississippians, who were probably ancestral Tunica, retreated back down the Arkansas River "to south of Dardenelle, where De Soto encountered them in 1541." The Caddoans then returned to the Spiro area to become the people of the Fort Coffee Phase (A.O. 1450-1500s). This sequence of events is a fascinating reinterpretation of regional culture history, unfortunately it falls flat when confronted by either contemporary theory or the data.
The Original Distribution of Bois D'Arc. Part I: Texas
Authors: Jurney David H.
Published: March 2019

Early historical explorations of the American frontier discuss many tree species and their uses, yet rarely mention bois d'arc (Maclura pomifera). Several important early expeditions sent by President Thomas Jefferson into the southwestern frontier provide the first evidence for the natural and culturally influenced range of the species. Bois d 'arc was important in the trade of Native Americans, specifically used for bow wood.

As early as 1804, John Sibley and Merriwether Lewis reported to President Jefferson about bois d 'arc, drawing on information derived from transplanted saplings and reporting that the source was ca. 300 miles away (i.e., along the Red River?). John Sibley, a temporary United States Indian Agent along the Red River in the early nineteenth century, reported a source of bois d'arc wooden bows among the Caddos of the Red River. With these bows they conducted a lively trade among Plains and southeastern Indian groups.
Historical Processes and the Political Organization of the Hasinai Caddo Indians
Authors: Hickerson Daniel A.
Published: March 2019

Recent archaeological and ethnohistoric research has begun to reveal the extent of the depopulation that took place among Native American societies as a result of epidemic diseases that were introduced, in some cases, even before direct continuous interaction with Europeans. The research of Henry Dobyns on native demographic trends in Florida has been particularly influential on recent views of Native American demographic decline. While somewhat controversial, the findings of Dobyns and others have stimulated further research focusing on other areas of North America, including the Caddoan region.
Continuing the Discussion of the Spiroans and Their Entrepots: A Reply to Brooks's Critique of My New Paradigm/or the Archeology of the Arkansas Valley
Authors: Schambach Frank
Published: March 2019

Although Brooks seems to agree with me that the archeology of the Arkansas Valley requires a new paradigm, he clearly believes that mine -- which he apparently considers a poorly founded Binfordian screed written primarily for its shock value -- is not the one. Where, according to Brooks, have I gone wrong in my work on the archeology of the Arkansas Valley? Which of my generalizations does he consider so poorly grounded empirically as to suggest, as he insinuates, professionally and perhaps even ethically questionable work, and in what ways does he consider them deficient?

Archaeological Investigations at 34WG220: A Prehistoric Occupation in the Arkansas River Valley of Eastern Oklahoma
Authors: Bartlett Robert
Published: March 2019

In January and February of 1997, the Oklahoma Department of Transportation (ODOT) conducted archaeological work at site 34WG220 within right-of-way for a project involving realignment of SH-72 just south of Coweta, Wagoner County, Oklahoma. The site investigation consisted of the monitoring of trench excavation as well as controlled machine stripping. A few prehistoric artifacts, none of which are diagnostic, were found during the investigation. However, two cultural features were discovered during the monitoring of the trench excavation. The features were investigated by hand excavation of a 1 x 2 test unit.
Late Caddoan Occupation Along Cowhide Bayou: An Update on the Belcher Mound and Village Sites
Authors: Girard Jeffery S.
Published: March 2019

In the early 1930s, a northwestern Louisiana farmer cleared an area along Cowhide Bayou near the small town of Belcher. As he attempted to level a rise with a slip, he encountered a human skeleton. Fortunately, although he continued work in the surrounding area, he left the rise alone. Dr. Clarence Webb heard of the find in 1936 and began a project that would continue more than 20 years. It resulted in what remains today as the most completely excavated and reported mound investigation in the Caddoan area. Webb's work at the Belcher Site (l6CD13) not only provided a remarkably detailed picture of the sequence of events relating to construction and use of a prehistoric mound, his analysis of the mound" s stratigraphic layers also served to establish a ceramic chronology for northwestern Louisiana.
A Bluff-Shelter Site in Pontotoc County, Oklahoma
Authors: Antle H. R.
Published: March 2019

In the wildly rugged hills near Canyon Springs, in southeastern Pontotoc County, Oklahoma, a unique sandstone formation has produced evidence of once sheltering a prehistoric people.

Technically, the sandstone is of the Wilcox series, and is faulted to a position above the McLish limestone beneath which it normally lies. The fault line runs from the north southward a distance of 25 yards, then runs at right angles to the east for 40 yards. The sandstone ranges from 6 feet in height on the northern extremity to 35 feet along the southeastern portion. Multiple fractures, generally parallel to the fault lines, have been recemented with dissolved siliceous material to make a highly resistant formation. Erosion takes place by exfoliation, giving to the rock mass, at a distance, a granitic appearance. Because of slanting fracture lines, the foot-wall of the fault, overthrust as it is, has broken off in places to form huge over-hangs that afford plentiful protection from the weather. It was in such an area evidence of a prehistoric habitation was found.
Notes on the Mollusca from Site 41DT59, Cooper Lake, Delta County, Texas
Authors: Todd Jesse
Published: March 2019

This paper focuses on the information about the mollusca from site 41DT59. The author takes the information from Dr. Fullington, the noted malacologist, and illustrates how the archeologist can take the information and apply it to site analysis. This information derived from the analysis mainly supports what the authors have concluded about site 41DT59, but does discuss material not covered in the original text. The analysis is divided into two sections. The information derived from the gastropods is discussed first, and the information derived from the mussels second.
Archeological Investigations at the Harrison Bayou Site (41HS240) in Harrison County, Texas
Authors: Perttula Timothy K. , Nelson Bo
Published: March 2019

We recently completed archeological investigations on approximately 1400 acres of land on Harrison Bayou, Longhorn Army Ammunition Plant, Harrison County, Texas, leased by the Caddo Lake Institute, Inc. (Perttula and Nelson 1999). The Caddo Lake Institute, Inc. leased this portion of the Longhorn Army Ammunition Plant (LHAAP) for 30 years under a September 1996 Memorandum of Agreement (MOA) with the Department of the Army. These archeological investigations were completed under Archeological Resources Protection Permit DACA63-4- 97-0580 issued September 1, 1997, by the Real Estate Division of the Department of the Army, Fort Worth District, Corps of Engineers to the Caddo Lake Institute, Inc.

During these investigations, intensive shovel testing and a limited amount of hand excavations were completed at the Harrison Bayou site (41HS240), one of the earliest reported Caddoan sites in Northeast Texas (Ford 1936), but still one of the more poorly known sites in the region. In this paper, we discuss the work we conducted at the Harrison Bayou site, and summarize the archeological findings from this important Middle Caddoan period occupation at Caddo Lake.
Current Status of the Norman Site, 34WG2
Authors: Vogle Louis E.
Published: March 2019

As defined by Finkelstein in his description of excavations at the site, the Norman site currently is completely located within the waters of Fort Gibson Reservoir, a U.S. Army Corps of Engineers (COE) lake on the Grand (Neosho) River in northeastern Oklahoma. Due to a combination of archeological excavations at the site during the 1930s and 1940s, pothunting, large-scale earthmoving activities associated with the construction of a nearby highway bridge, and approximately 50 years of wave action and seasonal inundation by Fort Gibson Reservoir, portions of Mounds I-1 and I-2 are all that remain of the Norman site.
The Norman Site Excavations Near Wagoner, Oklahoma
Authors: Finkelstein J. Joe
Published: March 2019

The Norman site is seven miles southeast of Wagoner, Wagoner County, Okla., on State Highway 51. It is on the upper terraces on the west side of Grand River just north of the approach to the new bridge. Principal mound is a double unit; the larger mound, clearly visible from the highway, is conical, 27' high and 90' in diameter; the low mound, on the north, is circular, 7' high and 100' in diameter; a low, broad saddle 12' long connects the 2 mounds. An extensive habitation area, Unit IV, extends to the north and northeast of Mound I-2. Unit II was also a double unit; the larger mound was originally conical, 70' in diameter and probably 10' high. It was only 6.5' high when excavated, owing to a large pit previously dug from the apex. The smaller mound, on the north, was circular, 2.5' high and 45' in diameter. The edges of the two mounds overlapped somewhat. Unit III is a low circular mound 7' high and 11 O' in diameter. Unit VI is a low, circular mound 1.5' high and 45' in diameter. Unit II was completely excavated; approximately one third of Unit II, a portion of Mound 1-2 and a portion of the habitation area were also excavated.
Temporal and Spatial Patterns in the Prehistoric Settlement of the Lake Bob Sandlin Area, Big Cypress Creek Basin, Northeastern Texas
Authors: Perttula Timothy K. , Nelson Bo
Published: March 2019

Since many of the archeological sites documented during the course of previous archeological investigations at Lake Bob Sandlin contain temporally diagnostic lithic, ceramic, and/or historic artifacts, we have the opportunity to investigate prehistoric temporal and spatial trends in the use of this part of the Big Cypress Creek basin in Northeastern Texas. The discussion of temporal trends in the prehistoric settlement of the Lake Bob Sandlin area is based on the findings from the 108 sites reported by Nelson and Perttula, the different components identified by Thurmond in the 95 sites recorded and investigated in the 1960s and 1970s, and information gained from various prehistoric sites recently recorded at Lake Bob Sandlin State Park.
Bossier Tribes, Caddo in North Louisiana's Pineywoods
Authors: Gibson Jon L.
Published: March 2019

Clarence Webb (1948) christened Bossier more than a half century ago. Its namesake was the northwestern Louisiana parish where several Bossier sites were located, but it could just as easily been named after Webster, Claiborne, Harrison, Columbia, or other political subdivisions in northwestern Louisiana, southwestern Arkansas, or eastern Texas where its distinctive pottery was found. This is Caddo country, linguistically and ethnically. Bossier is the issue of Caddoan cultural tradition, a culmination of agents, practices, and histories that transpired in the Red River valley and adjoining Pineywoods hills between ca. A.D. 1300 and 1500.

Bossier is best known for its pottery. Pottery hoists the load for this examination, but other factors such as presence or absence of mounds and relative geographic location help me contextualize Bossier pottery and contemplate Bossier materiality as the product of human minds and hands. I organize pottery data, new and old, by a simple arithmetic measure, an average index of similarity. I don't see how more robust statistical comparisons could do any better when data come from potsherds picked up from bare spots on the ground but not from underneath the pine straw. Powerful statistics don't create powerful data. They don't create data at all.
Note on a Possible Chipped Stone Grubbing Tool from Upshur County, Texas
Authors: Lintz Christopher , Largent Floyd
Published: March 2019

During the period August 6-27, and November 18-20, 2003, archeologists from Geo-Marine Inc. (GMI), of Plano, Texas, conducted a pedestrian survey of a 51.5 km-long corridor for the proposed Southside Regional Water System in Marion, Harrison, Upshur, and Gregg counties, Texas. The proposed waterline is intended to draw water from Lake O The Pines in the Big Cypress drainage system and distribute it to various communities in both the Big Cypress and Little Cypress Creek basins in the aforementioned counties. Specifically, the pipeline will benefit the communities of Ore City, Old Diana, Diana, and James before the pipeline crosses Little Cypress Creek and winds southeastward to a booster pump station for further distribution to other communities through existing pipelines. During the survey, random shovel testing near the community of James found an isolated, expended chipped stone "grubbing implement" made of gray siltstone. Due to the scarcity of such tools, and the desire to call attention to the locus of this unusual item, the State Historic Preservation Office suggested that GMI assign the location an archeological site number, rather than retain it as an isolated occurrence. The purpose of this brief note is to discuss the find location, describe this relatively unusual artifact, and draw comparisons with similar implements.
Archeological Investigations at the Hudnall-Pirtle Site (41RK4) An Early Caddo Mound Center in Northeast Texas
Authors: Bruseth James E. , Perttula Timothy K. , Fritz Gayle J. , Yates Bonnie C.
Published: March 2019

The Hudnall-Pirtle site (41RK4) is situated on a large T-1 alluvial terrace of the Sabine River in northern Rusk County in Texas. This area of the state, commonly called Northeast Texas, is part of the Southern Gulf Coastal Plain, a relatively level, sloping plain formed by the pre-Pleistocene embayment of the Gulf of Mexico.

From a biogeographical perspective, the site is located in the Oak-Hickory-Pine forest of eastern Texas, otherwise known as the Pineywoods. This area represents the western extension of the southern coniferous forests and is dominated by shortleaf and loblolly pine trees. Hardwood trees, including various oaks, hickory, elm, and gum, are the dominant vegetation in the floodplains of rivers and major creeks in Northeast Texas.
From Mounds to Monasteries: A Look at Spiro and Other Centers Through The Use of Metaphor
Authors: Brooks Robert L.
Published: March 2019

Previous study of the extensive and elaborate funerary offerings at the Spiro site have explained their presence by an exchange system with Spiro functioning as a gateway center. More recently, Schambach has argued extensively and passionately for Spiro’s role as an entrepôt redistributive center. However, this argument fails to account for much of the accumulation of funerary items present at Spiro. As an alternative, I propose that some ceremonial centers such as Spiro functioned solely as religious centers, much like the monasteries of medieval Europe with parallels in the use of architecture, economic support, relics, and the treatment of individuals at death. A model based on the metaphor of monastic life provides greater explanatory potential than that of the economically-driven entepôt.
The Organization of Novaculite Tool Production: Quarry-Workshop Debitage Comparisons
Authors: Trubitt Mary B.
Published: March 2019

Arkansas novaculite, outcropping in the Ouachita Mountains of Arkansas and Oklahoma, has been an important regional lithic resource for thousands of years. Because of the stone’s durability, by-products of past novaculite procurement and tool production and use activities litter the landscape in southwest Arkansas. Recent work situates novaculite quarries in the broader context of tool production and exchange systems. This article focuses on the organization of tool production, and explores analytical techniques that can be used to identify spatial separation of the lithic reduction process between quarry, workshop, and habitation sites.
Proposal for a 2007 Caddo Archaeology Summit Meeting
Authors: Perttula Timothy K.
Published: March 2019

The Caddo Indian peoples lived in parts of the four states of Arkansas (specifically southwest Arkansas), Louisiana (the northwestern part of the state), Oklahoma (the eastern region), and Texas (all of East Texas) from deep in prehistoric times until the early 1840s. They left behind an extensive archaeological record marked by important mound centers where the social and political elite lived and led community-wide rituals, ceremonies, and traditions; villages, hamlets, and farmsteads where the people carried out their daily lives; numerous cemeteries and burial grounds where the people were laid to rest following long-standing religious burial ceremonies; as well as salt-making sites, stone tool quarries, hunting camps, and other evidence of the Caddo people’s use of the land long before Americans settled the region.
Book Review: The American Indian Oral History Manual: Making Many Voices Heard
Authors: Gregory Pete
Published: March 2019

The times have changed. American Indian people, like indigenous population worldwide, have finally begun to impress scholars with the fact that in spite of centuries of colonial exploitation their cultures are alive and they hold ownership of them. Oral history and ethnology both have to listen to this new voice and come to understand the ethical and legal implications for the academic disciplines. These three authors bring unique experiences as well as “best practice training” to this small book.

Current Research: Discovery and Recovery of a 14th Century Dugout Canoe on the Red River, Caddo Parish, Louisiana
Authors: Girard Jeffrey , McGimsey Charles
Published: March 2019

In June 2017, Jenna Bradley and Robert Cornett were boating down the Red River in northern Caddo Parish, Louisiana, when they noticed an unusual log protruding from a sandy bank near the town of Belcher. After realizing that it was a dugout canoe, they contacted the Louisiana Department of Wildlife and Fisheries, and eventually word of the find was transmitted to state archaeologist Chip McGimsey at the Louisiana Division of Archaeology. The following day, Bradley and Cornett led Jeffrey Girard and Jameel Damlouji of the Louisiana Archaeological Society to the site. It was obvious that it was a dugout canoe of comparable size and form to one found in 1983 at the base of a steep cutbank on the east side of a now cut off channel of the Red River approximately 12 km (7 miles) downstream (Figure 1). At the time, the 1983 canoe was thought to be the largest prehistoric watercraft in the Southeastern United States measuring 9.35 m (or 30 ft. 8 inches) long and 56 cm (1 ft. 10 inches) in diameter. The newly discovered canoe is a little larger, measuring 10.2 m long (33.4 ft.) and approximately 60 cm (2.0 ft.) in diameter. Both boats have similar shapes with step-like seats carved into the ends (Figures 2 and 3), and both probably are made from cypress logs, although the wood of the recent find has not been identified with certainty.
Features and risk factors for recurrence of intradural spinal tumors
Authors: Byvaltsev V. A. , Stepanov I. A.
Published: March 2019

Spinal cord tumors include a variety of nosological units and are classified according to their localization and histological type. The search for literature sources in the Pubmed, EMBASE and eLibrary databases demonstrated the absence of studies devoted to study of the features and risk factors for the recurrence of intradural spinal tumors. the purpose of this study was to reveal features and risk factors of recurrence of intradural spinal tumors after microneurosurgical resection. material and methods. The study included medical records of 196 patients with intradural extramedullary and intramedullary spinal tumors. The extent of microneurosurgical tumor resection, clinical efficacy of surgery, and risk factors for recurrence of intradural spinal cord tumors were been analyzed. results. Improvement in neurologic deficit after surgery was noted in 116 (59.1 %) cases, neurologic status remained the same in 47 (24.0 %) patients, and worsening of neurological deficit was observed in 33 (16.8 %) cases. Total microneurosurgical resection of intradural spinal tumors was performed in 140 (71.4 %) patients, subtotal resection in 22 (11.2 %) patients, partial resection in 25 (12.7 %) patients and spinal cord decompression or biopsy and/or its roots were performed in 9 (4.6 %) of patients. The likelihood of recurrence-free survival of patients with benign intradural spinal cord tumors was significantly higher than that of patients with malignant tumors (p<0.001). Benign tumors (χ2=34.7, p<0.05), thoracic and lumbosacral tumors (χ2=10.3, p<0.05), low degree of neurological deficit (χ2=31.5, p<0.05), absence of syringomyelia/syringobulbia signs (χ2=13,2, p<0,05), as well as extramedullary tumors (χ2=12,6, p<0.05) allowed us to perform total degree microneurosurgical resection. Malignant tumors (χ2=34.8, p<0.05), cervical and thoracic tumors (χ2=8,4, p<0,05), high degree of neurological deficit (χ2=12,9, p<0.05), partial resection, biopsy or decompression of neural structures (χ2=9.7, p<0.05) and intramedullary tumors statistically significantly increased the risk of their recurrence. conclusion. Histological pattern, tumor localization, preoperative clinical and neurological deficit according to the McCormick classification and the extent of surgery are significant risk factors for recurrence of intradural spinal tumors.
Liver metastases in patients with curatively treated colorectal cancer
Authors: Rasulov R. I. , Yudin A. A. , Songolov G. I.
Published: March 2019

Background. The problem of the development of liver metastases in colorectal cancer patients previously treated with curative intent surgery remains little studied. Identification of significant factors affecting the occurrence of metachronous metastasis contributes to a more accurate prediction of recurrence in this group of patients. material and methods. In our study we analyzed the incidence of liver metastases and prognostic factors in 116 colorectal cancer patients previously treated with curative intent at Irkutsk Regional Cancer Center between 2006 and 2017. The patients received combined modality treatment including neoadjuvant radiotherapy or chemoradiotherapy for localized and locally advanced rectal cancer, radical surgery and adjuvant chemotherapy. After curative treatment, 96 patients had no evidence of distant liver metastases, and 20 patients developed distant metastases. results. The incidence of liver metastases was 17 %. In most patients, metastases occurred 16.5 months after completion of curative treatment, reaching peak incidence at 12–18 months. Prognostic factors of colorectal liver metastases in colorectal cancer patients previously treated with curative intent surgery were: the stage of the tumor, tumor growth in the parirectal/mesocolic fatty tissue, and no previous preoperative chemoradiotherapy and adjuvant chemotherapy. conclusion. For early detection of liver metastases, the carcinoembryonic antigen (CEA) measurements, contrast-enhanced abdominal multislice CT, and ultrasound-guided liver biopsy were recommended to perform every 3 months in the postoperative period.

Objective: to compare the morphological and functional properties of mesenchymal stem cells from mammary tissues and chemically-induced mammary tumor tissues. material and methods. The study included 25 female Wistar rats. In 20 rats, mammary carcinoma was induced by intramammary injection of N-methyl-N-nitrosourea after estrus synchronization with chorionic gonadotropin. The control group consisted of 5 rats. Mammary carcinoma was verified histologically and immunohistochemically. To examine, whether the cells isolated from normal tissue and tumor tissue belonged to mesenchymal stem cells, FACS Canto II flow cytofluorometer was used. The functional properties of mesenchymal stem cells were evaluated in MTT assay by the level of nitric oxide production in normal and by hydrogen peroxide-induced hypoxia. The levels of prolactin, luteinizing hormone and estradiol E2 in urine were studied using solid-phase enzyme-linked immunosorbent assay. results. Chemically-induced mammary tumor according to histological and immunohistochemical studies corresponded to luminal B type breast cancer in humans. In rats that developed mammary tumors, the urine prolactin levels after synchronization of estrus were increased. In rats that did not develop tumors, the levels of prolactin and luteinizing hormone were decreased, but the levels of estradiol E2 were increased. More mesenchymal stem cells with CD45-/CD90+phenotype were obtained from the breast tumor tissue. Mesenchymal stem cells from tumor tissue showed increased proliferative potential and were more resistant to hypoxia. conclusion. Tumor- associated mesenchymal stem cells having high proliferative potential and resistance to hypoxia were obtained from chemically-induced mammary tumor tissue. Morphologic and functional differences in mesenchymal stem cells obtained from mammary breast tissue and tumor tissue require further studies.

To study the mechanisms underlying the effects of intraperitoneal chemoperfusion and to develop the optimal chemoperfusion regimen, an animal model of peritoneal carcinomatosis closely resembles a human model of peritoneal carcinomatosis is required. In our study, the model of peritoneal carcinomatosis in rats with ascitic ovarian cancer was used. material and methods. There were three groups of rats with ascitic ovarian cancer: 1 – the control group (n=15) having no treatment; 2 – rats receiving normothermic intraperitoneal chemoperfusion with cisplatin, 40 mg/kg (n=12); 3 – rats receiving hyperthermic intraperitoneal chemoperfusion with cisplatin, 20 mg/kg (n=14). All animals were euthanized with subsequent autopsy. results. Ascitic ovarian cancer developed in 100 % of the animals injected with the tumor cells. The median overall survival of rats in the control group was 9.5 days. At autopsy, all rats had ascites, and rats surviving 15‒17 days after the tumor cell injection had white tumor nodes measuring 1–3 mm in the greater omentum, intestinal mesentery, parietal and visceral peritoneum. The nodes were histologically verified as metastases of low-differentiated ovarian tumor. In 2 and 5 rats from groups 2 and 3 respectively, metastases in paratracheal lymph nodes and tumor hydrothorax were detected with no evidence of peritoneal carcinomatosis. The median survival of rats in groups 2 and 3 was significantly higher than that in the control group, being 37.5 and 25.5 months, respectively (р=0,256). conclusion. This in vivo study proved that localization of ascitic ovarian tumor, development of the tumor in all animals injected with tumor cells, fast ascites progression and peritoneal carcinomatosis make this ascitic ovarian cancer an adequate preclinical model of peritoneal carcinomatosis to study intraperitoneal chemoperfusion. Further studies are needed to understand the reasons and mechanisms of the tumor hydrothorax development in rats after intraperitoneal chemoperfusion.

Residents in rural communities across Canada collect potable water from aquifers. Fecal contaminants from sewage and agricultural runoffs can penetrate aquifers, posing a public health risk. Standard methods for detecting fecal contamination test for fecal indicator bacteria (FIB), but the presence of these do not identify sources of contamination. In contrast, DNA-based diagnostic tools can achieve this important objective. We employed quantitative polymerase chain reaction (qPCR) and high-throughput DNA sequencing to trace fecal contamination sources in Wainfleet, a rural Ontario township that has been under the longest active boil water advisory in Canada due to FIB contamination in groundwater wells. Using traditional methods, we identified FIBs indicating persistent fecal pollution in well waters. We used 16S rRNA sequencing to profile groundwater microbial communities and identified Campylobacteraceae as a fecal contamination DNA marker in septic tank effluents (STEs). We also identified Turicibacter and Gallicola as a potential cow and chicken fecal contamination marker, respectively. Using human specific Bacteroidales markers, we identified leaking septic tanks as the likely primary fecal contamination source in some of Wainfleet's groundwater. Overall, the results support the use of sequencing-based methods to augment traditional water quality testing methods and help end-users assess fecal contamination levels and identify point and non-point pollution sources.

Paternidades a distancia: Malestares de padres separados de sus hijas e hijos tras la deportación
Authors: Torre Cantalapiedra Eduardo , Rodríguez Gutiérrez Maritza
Published: March 2019

El objetivo de este trabajo es detectar y analizar los malestares que experimentan los padres al quedar separados de sus hijas/os tras ser deportados. Con base en cinco entrevistas a varones mexicanos deportados de Estados Unidos a la ciudad fronteriza de Tijuana, Baja California, exploramos los malestares que eventualmente experimentaron estos hombres por la separación física de sus hijas/os en relación con ser padres y con los mandatos de proveer y de ser afectivos con ellas/os. Adicionalmente, se reflexiona desde un plano principalmente teórico sobre los malestares de los hombres en la paternidad, especialmente, en el caso de las paternidades a distancia. Los padres entrevistados muestran malestares y otros padecimientos por no estar cerca de sus hijas/os para proveerles, cuidarles, disfrutar y establecer una relación de afecto con los mismos. Las conclusiones obtenidas, aunque preliminares, revelan rumbos para futuras investigaciones sobre paternidades y deportación.
Premature Ovarian Insufficiency and Long-Term Health Consequences
Authors: Tsiligiannis Sophia , Panay Nick , Stevenson John C.
Published: March 2019

Premature ovarian insufficiency (POI) is defined as the cessation of ovarian function before the age of 40 years. The trio of amenorrhea, elevated gonadotropins and oestrogen deficiency is associated with long-term health consequences including increased cardiovascular disease (CVD), decreased bone mineral density (BMD), significantly reduced fertility, psychological distress, vulvovaginal atrophy, neurological effects and overall reduced life expectancy. There are deficits in our understanding of this condition and subsequently the long-term health consequences. The underlying aetiology of POI and the optimal management strategies are also poorly understood. Our knowledge of long-term cardiovascular consequences specifically relating to women with POI is limited as most data on the subject are derived from studies involving women who experienced menopause at the natural age (after 40 years with an average age of 51).

BACKGROUND

The prevalence of childhood obesity is increasing in China, and the effect of mobile phone short message service (SMS) interventions to prevent early childhood obesity needs to be evaluated.

OBJECTIVE

The objective of this study was to assess the effect of an SMS intervention on the prevention of obesity in young children.

METHODS

A quasi-experimental design SMS intervention was carried out in 4 community health centers (CHCs) in Shanghai, China. A total of 2 CHCs were assigned to the intervention group, and 2 CHCs were assigned to the control group. Mothers in the intervention group received weekly SMS messages on breastfeeding and infant feeding from the third trimester to 12 months postpartum. The primary outcomes were children’s body mass index (BMI), BMI z-score, and weight-for-length z-score at 12 and 24 months. Factors associated with higher BMI and weight-for-length z-score at 24 months were also assessed.

RESULTS

A total of 582 expectant mothers were recruited at the beginning of the third gestational trimester. 477 (82.0%) and 467 (80.2%) mothers and their children were followed up to 12 and 24 months postpartum, respectively. There were no significant differences in children’s BMI, BMI z-score, and weight-for-length z-score at 12 and 24 months between the 2 groups. Factors associated with higher BMI, BMI z-score, and weight-for-length z-score at 24 months included higher birth weight, introduction of solid foods before 4 months, and taking a bottle to bed at 12 months.

CONCLUSIONS

The SMS intervention did not show a significant effect on children’s BMI, BMI z-score, or weight-for-length z-score at 12 and 24 months. Introduction of solid foods before 4 months and taking a bottle to bed at 12 months were significantly and positively correlated with a higher BMI, BMI z-score, and weight-for-length z-score at 24 months. Further studies with more rigorous design are needed to evaluate the effect of SMS interventions on preventing early childhood obesity.
Cross-sectional study of quality of life, cortisol, testosterone, and metabolic abnormalities in male schizophrenics (Preprint)
Authors: Zhu Yuncheng , Jiang Xixi , Ji Haifeng
Published: March 2019

BACKGROUND

Compared with demography and symptomatology of schizophrenia, the treatment strategies1 and quality of life (QOL) for patients are of more urgent concern for the therapeutic alliance.

OBJECTIVE

The study aims to investigate the current situation and correlation of metabolic characteristics of male schizophrenics by measuring serum concentrations of cortisol and testosterone related with metabolic abnormalities in male schizophrenics.

METHODS

The 174 patients were grouped based on their risk of metabolic syndrome (MetS),into Non-MetS, High-risk-MetS (HR-MetS), or MetS groups. Multiple linear regression analysis was used to associate the correlations between WHO Quality of Life-BREF (WHOQOL-BREF) score and five metabolic indices (Body mass index (BMI), Mean arterial pressure (MAP), Cholesterol, Triglyceride and Fasting blood glucose (FBG)). Metabolic diseases were associated with cortisol and testosterone levels using Pearson’s correlations.

RESULTS

Compared to HR-MetS and MetS groups, the WHOQOL-BREF score in Non-MetS group has statistical difference. Multiple linear regression via stepwise analysis eventually constructed a regression model of WHOQOL-BREF score with four variables including MAP, IQ, FBG and age. The triglyceride level was positively correlated with the cortisol level while all the five metabolic indices were negatively correlated with the testosterone level.

CONCLUSIONS

In the five metabolic indices, the risks of hyperglycemia and hypertension are correlated with the quality of life in male schizophrenics rather than those of obesity or hyperlipidemia. The correlation analysis then showed that there was a weak linear correlation between testosterone level and all of the five metabolic indices.

CHRISTIANITY AND ECOLOGY A CRITICAL STUDY ON THE CONTRIBUTION OF SDA THEOLOGY TOWARD ECOLOGY
Authors: Abdi M Rizal , Pardamean Ferry Goodman
Published: March 2019

To date, the controversial publication of Lynn White Jr’s article, The Historical Roots of Our Ecological Crisis (1967) ignites the fierce debate between theologian and academia in the field of religion and ecology about the guilt of Western Christianity toward modern ecological calamity. Meanwhile, as a Christian denomination that highly emphasizes on the second coming (the Advent) and the next life, Seventh-Day Adventist (SDA) Church doctrine is frequently accused as the reason why Christianity doctrine tend to put aside today’s environmental problem and more focused in the eternal next life. Though, at the same time, SDA Church also known for its emphasis on holistic life as well as one of the most advanced church in health and medical science. Given those handicap, the research tries to challenge those common perceptions about Christianity and ecology right into the heart of its criticism. By using literature-based research as methodology, this paper scrutinizes the doctrine of SDA church within the context of ecology as well as demonstrates how the SDA Church manifests its ecological doctrines. Furthermore, on wider discourse of religion and ecology, the explorations on SDA theology shows that rather than becoming a source of problem, the eschatological doctrine might become the driven-factor toward ecological practices nowadays.
MENERAWANG MASA LALU DI ERA DIGITAL: FILM SEJARAH VIS A VIS HISTORIOGRAFI
Authors: Hakim Luqman Abdul
Published: March 2019

In recent years historical film production or historical films — Historical Film, Historical Movie, Historical Cinema—have become increasingly massive in Indonesia. In its development, historical films in Indonesia are a massive medium to present a past that deserves to be remembered as a collective memory of society. Since the reform era, dozens of historical film titles have been produced and colouring the Indonesian film industry. As a result, many historical films have become references and reference sources for the community to find information about the past. It becomes reasonable to see the development of multimedia-based information technology (audiovisual) which has encouraged the emergence of post-literacy phenomena. In historical studies, historical films can be studied as a thematic study as well as in a methodological realm. As a thematic study, historical films are mental products (mentifact) and social products (sociofact) of society in a certain space of time. Whereas in the methodological realm, historical films can be explored through debates about historical sources or as narratives and representations of the past presented through film media. The study of historical films as a study of history is still a rare and less desirable subject for historians in Indonesia. This paper utilizes literature studies to answer some of the research problems posed. Literature studies of sources related to historical film studies are the focus of the researchers. In addition, a deeper understanding of the development of historical films in Indonesia is also a concern to uncover the souls of the times that surround historical film production. This study concludes that the existence of historical films in the present is a challenge for historians to face the era of openness and variety of media that presents information about the past.
