Abstract:

The aim of the study was to develop an orthopedic implant coating in the form of vancomycin-loaded collagen/hydroxyapatite layers (COLHA+V) that combine the ability to prevent bone infection with the ability to promote enhanced osseointegration. The ability to prevent bone infection was investigated employing a rat model that simulated the clinically relevant implant-related introduction of bacterial contamination to the bone during a surgical procedure using a clinical isolate of Staphylococcus epidermidis. The ability to enhance osseointegration was investigated employing a model of a minipi

Abstract:

Abstract Given adipose tissue is histologically classified as connective tissue, we hypothesized expression of extracellular matrix (ECM) components are significantly altered during adipogenesis. However, little is known about the regulation of the ECM during adipose tissue development in the pig. Therefore, the objective of this study was to characterize expression of ECM components during porcine adipogenesis. Primary cultures of adipose tissue stromal-vascular cells were harvested from 3-day-old neonatal pigs (n=6) and preadipocytes induced to differentiate in vitro for 8 days in the presen

Abstract:

Ongoing controversy over the identification of mesoamerican centers as the locus for specialized production of stone tools is addressed by reference to a consumer locality in the eastern Maya Lowlands. Lithic data from Pulltrouser Swamp are used to shed light on the production intensity and scale of a distribution system centered at Colha, Belize. Debitage analyses of technological attributes, use wear, and metric dimensions contrast two contexts of lithic procurement at Pulltrouser Swamp: direct procurement of raw material and indirect procurement of finished tools.

Abstract:

A reexamination of the data presented by Shafer and Hester (1983) indicates that the level of specialized production and volume of intersite exchange of chert tools in the area of Colha has been greatly overstated. Evaluation of rates of production over time suggests that at most a few thousand chert tools were produced per year at Colha, indicating a very low level of specialization, if any. The context of the chert debitage deposits is suggestive of domestic production for household use, rather than the “industrial-level mass production” postulated by Shafer and Hester.

Abstract This study explores the early use of obsidian at the Maya site of Colha in northern Belize and the implications that variations in source distribution have for the site and its regional connections. Energy dispersive x-ray fluorescence (EDXRF) analysis of 104 specimens of obsidian from Preclassic contexts at the site identified El Chayal obsidian as the most common overall followed closely by that from San Martin Jilotepeque. Ixtepeque obsidian, not common in many Preclassic assemblages, was also strongly represented. The results revealed a Middle Preclassic dependence on San Martin o

AbstractOngoing fieldwork at the coastal site of Northern River Lagoon (NRL) in northern Belize, a specialized saltmaking community, has revealed a consumer relationship with the large, inland, stone-tool-producing center of Colha during the Late to Terminal Classic. Artifact distribution suggests that this economic partnership involved the movement of salt, salted products, and trade goods to Colha in exchange for stone tools. This inland–coastal partnership was enhanced by a shared ideology reflected in the iconography of identical Palmar Orange-polychrome plates. The presence of the ideolog

Abstract:

This study provides a synthetic review of the Terminal Classic collapse of the Maya site of Colha, Belize, based on new data drawn from recent lithic and osteological studies and previously reported information. The well-known Colha skull pit has figured prominently in previous hypotheses of the site's collapse, which focus on either warfare or ritual termination. In this review, these two hypotheses are reexamined using data from: (1) shifts in settlement patterns; (2) transitions in lithic production; and (3) the death en masse of at least 55 individuals coincident with the site's abandonmen

Abstract:

Spouted vessels are diagnostic forms of Middle Preclassic (1000–400 B. C.) and Late Preclassic (400 B. C.-A. D. 250) Maya ceramic assemblages. Mayanists have traditionally called these vessels “chocolate pots,” but until recently there has been little direct evidence to support this interpretation. In fact, few studies have focused on the role these specialized forms played in the daily social and ritual activities of the ancient Maya. This paper provides a contextual and functional analysis of Preclassic spouted vessels found across the Maya lowlands and highlands. Additionally, the results o

We reassess San Estevan's role within the Late Formative period political geography of northern Belize. This medium-sized site has been interpreted as a subsidiary center to Nohmul that ruled the area along with Cerros, Lamanai, and Colha (Scarborough 1991). It has also been suggested that scores of autonomous polities existed in the region at this time (McAnany 1995). We examine these contrasting models in light of our recent excavations in the central precinct of San Estevan. These excavations reveal a stratigraphic sequence of Middle through Late Formative period deposits. Excavations docum

Abstract:

Abstract Mechanisms by which leptin stimulates collagen α1(I) [Col1a(I)] gene expression are unclear. The purposes of this study were to identify the trans-acting factors and cis-acting elements in Col1a(I) promoter involved in this effect as well as the pathways that are implicated. In primary cultures of rat hepatic stellate cells (HSCs), we measured the effects of leptin on Col1a(I) gene and protein expression and on the binding of nuclear proteins to the Col1a(I) promoter. We found that leptin increased Col1a(I) gene and protein expression in activated HSCs. Transient transfections showed

Abstract:

Background: Nanohybrid composite has filler with variation of size and contain nano-sized particles. The decreasing of surface hardness can be occured because consumption of acid pH beverages, carbondioxide (CO2) from soft drinks and water. Sugary soft drink (coca-cola) has lower pH than aspartame soft drink (coca-cola zero). Besides the difference of pH, aspartame soft drink (coca-cola zero) contains fenilalanin amino acid the product of hydrolisis reaction of aspartame so the acid environment become neutral. Purpose: To view the differences of nanohybrid resin composite after being soaked in

Abstract:

Infection is one of several factors that can delay normal wound healing. Antibacterial wound dressings can therefore promote normal wound healing. In this study, we prepared an antibacterial wound dressing, consisting of visible light-cured methacrylated collagen (ColMA) hydrogel and a 2-hydroxypropyl-beta-cyclodextrin (HP-β-CD)/triclosan (TCS) complex (CD-ic-TCS), and evaluated its wound healing effects in vivo. The 1H NMR spectra of ColMA and CD-ic-TCS revealed characteristic peaks at 1.73, 5.55, 5.94, 6.43, 6.64, 6.84, 6.95, 7.31, and 7.55 ppm, indicating successful preparation of the two m
