Release of Spectrin-Containing Vesicles from Human Erythrocyte Ghosts by Dimyristoylphosphatidylcholine (1996)

Membrane vesicles, which were released from human erythrocyte ghosts by dimyristoylphosphatidylcholine (DMPC), showed a protein composition similar to that of the erythrocyte membrane, despite a reduction of in spectrin content. The spectrin content of vesicles decreased with increasing hemoglobin concentration within ghost membranes, but increased upon exposure of hemoglobin-free ghosts to a pressure of 100 MPa. The ESR spectra of spin-labeled membrane proteins showed that membrane proteins in ghosts became unfolded at high pressure. Furthermore, spectrin-poor and protein 4.1-rich vesicles were released by DMPC from diamide-treated ghosts in which spectrin was cross-linked and stabilized. Taking into account that the spectrin tetramer is stabilized by hemoglobin [Liu and Palek (1984) J. Biol. Chem. 259, 11556-11562], these results suggest that the spectrin content of DMPC-induced vesicles from erythrocyte ghosts increases with increasing instability of the cytoskeletal network in parent cells.
Molecular modelling and biological evaluation of a series of hydroxylated benzylideneanilines and benzylamines designed as tyrosine kinase inhibitors. (1997)

A series of hydroxylated benzylideneanilines and benzylamines were prepared and tested for inhibition of epidermal growth factor receptor-associated protein tyrosine kinase (PTK) activity in vitro. Molecular modelling and analysis of the biological results lead us to propose a minimal structural pharmacophore for two distinct binding sites within the PTK domain.

Observation of the cross-excitation instability in a relativistic backward wave oscillator (1998)

Experimental observation of the cross-excitation instability in a relativistic backward wave oscillator is reported. The transition between single frequency operation and the cross-excitation regime is measured. The initial mode excited in the cross-excitation regime has a relatively low efficiency, while the second mode has considerably higher efficiency and a slightly higher frequency. The two modes are observed to be beating for a considerable fraction of the radiated microwave pulse. These results are consistent with earlier theoretical predictions for the onset and voltage scaling for this instability.
Detection of genotype‐environment interaction in case‐control studies of birth defects: How big a sample size? (1995)

Detecting interactions between risk factors in case-control studies of birth defects and other conditions usually requires increasing the sample size beyond that needed to detect marginal effects. A special case of such interaction is genotype-environment interaction in which the effects of an exposure on disease risk are modified by genetic susceptibility. When case-control studies are designed to detect marginal effects of an exposure (i.e., in the whole population), under many plausible interaction schemes, no additional case and control subjects are needed to detect genotype-environment interaction. On the contrary, inclusion of genotypic information generally can improve the statistical power of the original study. Using the example of oral clefts, maternal cigarette smoking, and genetic variation at the transforming growth factor alpha gene, we illustrate sample size and power issues in designing case-control studies when prior information is available on both the marginal effects of the exposure and the genetic factor.
Overlapping camera clustering through dominant sets for scalable 3D reconstruction (2013)

In this work we present a method for clustering large unordered sets of cameras. Our method uses camera view information available from Structure-from-Motion (SfM) for computing a set of overlapping clusters suited for Multi-View Stereo (MVS) reconstruction. Our formulation of the problem uses the game theoretic model of dominant sets to find competing clustering solutions with computational simplicity. The overlapping solutions ensure more robust partial reconstructions. Experimental evaluations show that our method produces more regular cluster and overlap configurations with respect to the state of the art. This allows more scalable and higher quality reconstructions, while speeding up 6 times with respect to a MVS which uses all images at once.
Radiation absorbed dose estimates for positron emission tomography (PET): K-38, Rb-81, Rb-82, and Cs-130. (1982)

Radiation absorbed dose estimates were made for K-38, Rb-81, Rb-82, and Cs-130, potential radionuclides for myocardial and brain studies with positron emission tomography (PET). Biodistribution data for K-42, Rb-86, and Cs-137 in rats were used, together with the most recent radiation absorbed dose computational techniques and data. Renal radiation absorbed doses for K-38, Rb-81, Rb-82, and Cs-130 were estimated to be 56, 120, 19, and 150 mrad, respectively, per mCi administered. Corresponding radiation absorbed doses in the heart were 42, 54, 13, and 68 mrad/mCi. Radiation absorbed doses in the brain of 1.3, 3.5, 0.25, and 3.7 mrad/mCi were estimated for these four radionuclides.

Amine plasma modification of polyaramid filaments (1983)

Amine plasmas offer a method to implant amine groups into the surface structure of polyaramid filaments. These amines will react with epoxy to form covalent bonds at composite interfaces. They may also be chemically modified for reaction with other polymerizing matrices. The covalently bound interface exhibits an increased resistance to peel forces. Fractured surfaces show a change in failure mode from interface dominated to a mixture of filament splitting and matrix cracking as amine content is increased. Thus, the weak link in determining off-axis strengths of polyaramid/epoxy is changed from the interface to the filament and matrix bulk strengths after amination. The covalently bonded interface should also exhibit improved hygrothermal stability. The kinetics of amination are rapid - surface saturation occurs in 30 s; however, the kinetics are sensitive to oxygen concentration. Filament tensile strength is unchanged by amine plasma treatment times less than 600 s. Spectroscopic analysis indicates that the surface structure may, nevertheless, be substantially altered.
VISUAL FUNCTION MEASURES IN EARLY AND INTERMEDIATE AGE-RELATED MACULAR DEGENERATION (2016)

This pilot study supports the feasibility and reliability of using LLVA, microperimetry, and CCT in early dry AMD. Our data suggest these measures can be used as alternative future clinical trial endpoints. A larger, prospective natural history study of alternative visual function measures in dry AMD is warranted.
Compositional, Physical, and Wet‐Milling Properties of Accessions Used in Germplasm Enhancement of Maize Project (2001)

ABSTRACT Forty‐nine accessions used in the Germplasm Enhancement of Maize (GEM) project, two commercial hybrids (Pioneer Brand Hybrids 3394 and 3489), and two Corn Belt inbreds (B73 and Mo17) were evaluated for compositional, physical, and wet‐milling properties. GEM accessions had lower starch contents (65.9–69.1% vs. a mean of 72.2% for the commercial hybrids) and greater protein contents (12.0–14.4% vs. a mean of 8.2% for the commercial hybrids) than did the improved Corn Belt material. Absolute densities were consistently higher for the GEM accessions compared with the commercial hybrids (1.320 vs. 1.265 g/cm 3 , respectively). The wet‐milling characteristics of the GEM accessions were not nearly as good as for the commercial hybrids. Mean starch yields were only 54.3% for the GEM accessions versus 64.8% for the commercial hybrids. Residual protein levels in the starches recovered from the GEM accessions were much greater (0.45–2.03%) than for commercial corn hybrids (<0.3%).
Biological Activities and Proteomic Profile of the Venom of Vipera ursinii ssp., a very Rare Karst Viper from Croatia (2020)

The karst viper (<i>Vipera ursinii</i> ssp.) favours high-mountain dry grasslands in southern and south-eastern Croatia. It is medically less important than other <i>Vipera</i> species, because of its remote habitat and the very small amount of venom that it injects by its relatively short fangs. The scientific literature on <i>Vipera ursinii</i> deals mostly with the morphology, ecology and distribution range of this snake, due to the species' conservation issues, while the toxinological aspects of its venom have not so far been investigated. Here we report on the composition and biological activity of the <i>Vipera ursinii</i> ssp. venom. Using a proteomics approach, we have identified 25 proteins in the venom that belong to seven protein families: snake venom metalloproteinase, serine protease, secreted phospholipase A<sub>2</sub>, cysteine-rich secretory protein, snake C-type lectin-like protein, serine protease inhibitor and nerve growth factor. The <i>Vipera ursinii</i> ssp. venom was found to be distinctively insecticidal. Its lethal toxicity towards crickets was more than five times greater than that of <i>Vipera ammodytes ammodytes</i> venom, while the opposite held in mice. Interestingly, the mode of dying after injecting a mouse with <i>Vipera ursinii</i> ssp. venom may suggest the presence of a neurotoxic component. Neurotoxic effects of European vipers have so far been ascribed exclusively to ammodytoxins and ammodytoxin-like basic secreted phospholipases A<sub>2</sub>. Structural and immunological analyses of the <i>Vipera ursinii</i> ssp. venom, however, confirmed that ammodytoxin-like proteins are not present in this venom.
Unsteady Methods to Investigate Inlet Distortion in a Transonic Tail Cone Thruster Fan Stage With Boundary Layer Ingestion (2020)

Abstract Boundary Layer Ingestion (BLI) engines have the potential to offer significantly reduced fuel burn, but the fan stage must be designed to run efficiently with a distorted inflow. It must also be able to withstand unsteady aerodynamic loads resulting from a non-uniform flowfield. In a multidisciplinary turbomachinery design cycle involving such a complicated flowfield, high fidelity numerical solutions are required. Two high fidelity unsteady Reynolds Averaged Navier-Stokes (URANS) methods for accurate analysis of a Tail Cone Thruster (TCT) transonic fan stage subjected to inlet distortion have been implemented. They are frequency domain based non-linear harmonic (NLH) and full-annulus complete time domain based time marching methods. This paper demonstrates that the relevant parameters required to accurately compute aerodynamic performance of a fan stage in distorted conditions can be accurately modelled with a few harmonics using the NLH method in a fraction of time compared to the full annulus time marching method. However, the complete aerodynamics of distortion transfer across different blade rows of a fan stage can only be analyzed using the time marching solution. Several physical mechanisms which govern the fan response to an inlet distortion and how different distortion profiles impact the aerodynamic performance of this fan stage are also explained.

Evaluation of Two Modeling Methods for Generating Heavy-Truck Trips at an Intermodal Facility by Using Vessel Freight Data (2005)

A methodology for building a truck trip generation model by use of artificial neural networks from vessel freight data has been developed and successfully applied to five Florida seaports. The backpropagation neural network (BPNN) algorithm was used in the design. Although the methodology was sound, a new model had to be developed for each of these intermodal facilities. Lead and lag variables were necessary input variables for most models to account for commodities stored on port property before export or pickup after import. Other modeling techniques were researched, and a fully recurrent neural network (FRNN) trained by the real-time recurrent learning algorithm was selected to develop a model for Port Canaveral and compare with a BPNN model. FRNN is dynamic in nature and was found to relate to the storage time of the commodities to truck trip generation. A developed Port Canaveral BPNN model was successfully validated at the 95% confidence level with collected field data. It was applied to conduct a short-term forecast of the port's truck traffic for 5 years. The average annual growth of trucks based on the estimated freight activity under the BPNN model was 5.07%. The Port Canaveral FRNN model adequately estimated the current conditions but failed to forecast truck growth. The FRNN model required more data for forecasting than backpropagation. However, when more consecutive data are available for training, FRNN may produce more accurate results.

XPAND Patient-Activated Controlled Tissue Expander System for Breast Reconstruction (2014)

PURPOSE: Implant-based breast reconstruction is the most common method of breast reconstruction in the United States and frequently involves a two-stage approach with tissue expanders. A novel patient-activated controlled expander, the AeroForm tissue expander, has been developed which obviates the need for saline injections associated with traditional expansion. Our objective was evaluation of the safety and effectiveness of the patient-controlled tissue expander compared to traditional saline expanders in a prospective, multicenter, randomized, controlled clinical trial. METHODS: Subjects, ages 18-70 with BMIs ≤33, were enrolled and randomized using a 2:1 permuted block design to either the investigational patient-controlled tissue expander or the saline expander control group and underwent immediate or delayed breast reconstruction. Patient-controlled expansion was performed using a 10-cc dose volume up to 30-cc/day. Saline expansion was performed according to current standard of care using percutaneous saline injections. Primary effectiveness was measured based on successful exchange to permanent implants. Failures to exchange due to device related events were considered study failures. Secondary outcome measures included time to desired expansion/exchange, pain scores and ease of use. RESULTS: The trial, conducted at seventeen clinical sites in the US, has enrolled 115/138 planned subjects with 107 (69 AeroForm/38 saline) treated. Successful exchange has been achieved in 61 of 69 subjects in the investigational arm and 36 of 38 subjects in the control arm. The reasons for failure to exchange were cellulitis, delayed wound healing, erosion, under-expansion or over-expansion. Mean time to desired expansion is 18.2 ± 9.2 days (AeroForm) and 57.4 ± 33.6 days (saline). Mean time to exchange is 106.3 ± 42.9 days (AeroForm) and 151.7 ± 62.6 (saline). CONCLUSIONS: The investigational expander provides, relative to saline expanders, a needle free, time conserving and more convenient method of tissue expansion for breast reconstruction and is associated with high patient and physician satisfaction.

Unique characteristics of ERTS (1973)

The manned spaceflights have demonstrated what film cameras can do in space and they could provide a data source from which maps would be one of the principal products. ERTS was not defined with mapping as one of its principal objectives, but with ERTS-1 in orbit certain unique characteristics or advantages of the electronic transmission (TV) earth sensing system become apparent to the mapmaker. Six of the more obvious advantages over aircraft and satellite film systems are: (1) long life and coverage; (2) near real time; (3) orthogonality; (4) radiometric fidelity; (5) extension into the near IR wavelengths; and (6) extension into the thermal wavelengths.

Phospholipase A<sub>2</sub> Hydrolysis of Phospholipids: Use of <sup>31</sup>P NMR to Study the Hydrolysis, Acyl Migration, Regiospecific Synthesis, and Solubilization of Phospholipids (1981)

Our laboratory has been studying the kinetics (1) and mechanism of action (2) of phospholipase A2 which catalyzes the hydrolysis of the fatty acyl chain in the sn-2 position of phospholipids to give the 1-acyl lyso-phospholipid product: Recently, we found that phosphorylcholine-containing lipids activate the enzyme from cobra venom (Naja naja naja) toward phosphatidylethanolamine (PE) (3,4). These studies led to the suggestion of two sites for the enzyme - an activator site with minimum specificity for phosphorylcholine and a hydrophobic chain and a catalytic site with less specificity for the polar group. We have now extended these studies to synthetic phospholipids that contain short chain fatty acyl groups and which are water soluble, such as dibutyryl and dihexanoyl phosphatidylcholine (PC). These phospholipids are monomeric below their critical micelle concentration (cmc), yet activate the enzyme. In order to carry out kinetic studies, the long chain phospholipid substrate must generally be solubilized
[Squamous cell carcinoma developing in necrobiosis lipoidica in a diabetic patient]. (2015)

The development of squamous cell carcinoma in chronic and/or non-healing ulcers associated with necrobiosis lipoidica (NL) is rare, but should be considered in diabetic patients. NL is a non-infectious granulomatous degenerative skin disease. The prevalence of NL in diabetic patients is estimated to 0,3-1,2%. Awareness of malignant transformation potential within a plaque of NL is crucial for early diagnosis and easy radical treatment. A case from our outpatient diabetes clinic is presented.
