Cost Comparison of Industry Versus In-House Three-Dimensional Printed Models for Microvascular Mandible Reconstruction.

Computer-aided design and manufacturing can enhance microvascular mandible reconstruction, particularly in cases with preexisting segmental defects or exophytic tumors where precise in situ plate bending is difficult. However, its high cost may limit its use in high-volume academic centers. To compare the costs of industry-performed patient-specific milled locking mandibular reconstruction plates (LMRPs) and surgeon-performed plate bending using 3D-printed (3DP) models as measured by billing data.

Objective Photoanalysis of Feminizing Frontal Cranioplasty Outcomes.

Study Design: Retrospective analysis at a tertiary care center.

Objective: This study describes a method of analyzing postoperative results using lateral view clinical photographs to create normalized projection ratios of the glabella and radix.

Methods: We reviewed preoperative and postoperative photographs of 15 patients.

Oral Microbiome Profiling in Smokers with and without Head and Neck Cancer Reveals Variations Between Health and Disease.

While smoking is inextricably linked to oral/head and neck cancer (HNSCC), only a small fraction of smokers develop HNSCC. Thus, we have sought to identify other factors, which may influence the development of HNSCC in smokers including microbiology. To determine microbial associations with HNSCC among tobacco users, we characterized oral microbiome composition in smokers with and without HNSCC.

Recent changes in soil total phosphorus in the Everglades: Water Conservation Area 3.

We assessed recent changes in the distribution of soil total phosphorus (TP) in Water Conservation Area 3 (WCA-3) of the Everglades. Soil cores were collected in 1992 and 2003 at 176 sites. To reflect hydrologic boundaries within the system, WCA-3 was divided into three zones (3AN, 3AS, and 3B).

Evaluating ecological condition using soil biogeochemical parameters and near infrared reflectance spectra.

Rapid, repeatable assessment of ecological condition is critical for quantitative ecosystem monitoring. Soils provide a sensitive, integrative indicator for which sampling and analysis techniques are well defined. We evaluated soil properties as indicators of ecological condition (subjectively classified into minimally/moderately/severely degraded based on vegetative, hydrologic and edaphic cues) at 526 sites within Ft.

Visible-near infrared reflectance spectroscopy for rapid, nondestructive assessment of wetland soil quality.

Recent evidence supports using visible-near infrared reflectance spectroscopy (VNIRS) for sensing soil quality; advantages include low-cost, nondestructive, rapid analysis that retains high analytical accuracy for numerous soil performance measures. Research has primarily targeted agricultural applications (precision agriculture, performance diagnostics), but implications for assessing ecological systems are equally significant. Our objective was to extend chemometrics for sensing soil quality to wetlands.

Nutrient and hydrology effects on soil respiration in a northern Everglades marsh.

Microbial respiration in peat and overlying plant litter, as influenced by water level and phosphorus enrichment, was evaluated for an Everglades (Florida, USA) marsh ecosystem by measuring CO2 and CH4 release from soil-water microcosms. Intact cores of peat, overlying plant litter, and surface water were collected at seven locations in cattail (Typha domingensis Pers.) and sawgrass (Cladium jamaicense Crantz) stands along a phosphorus (P) enrichment gradient in Water Conservation Area 2A (WCA-2A).

Spatio-temporal patterns of soil phosphorus enrichment in Everglades water conservation area 2A.

The Florida Everglades have undergone significant ecological change resulting from anthropogenic manipulation of historical regimes of hydrology, nutrient loading, and fire. Water Conservation Area 2A (WCA-2A) in the northern Everglades has been a focal point for the study of ecological effects of nutrient loading, especially phosphorus (P), from the nearby Everglades Agricultural Area (EAA). The overall objective of our study was to evaluate recent (1990 to 1998) changes in the spatial extent and patterns of soil P enrichment in Everglades WCA-2A.

Selection of a lysine-resistant CHO-K1 mutant with reduced amino acid transport through multiple systems.

High levels of L-lysine were used to select for resistant variants of Chinese hamster ovary (CHO-K1) cells. Surviving colonies were screened for altered lysine transport and two with reduced uptake were picked. Clone CH-Kr, derived from the more severely affected colony, was analyzed in detail.
