Osteoinduction in the Presence of Chitosan-Coated Porous Hydroxyapatite (1995)

Hydroxyapatite nails, prepared according to a novel method and endowed with better mechanical resistance, were coated with chitosan to impart enhanced biocompatibility and were introduced in the femurs of rabbits. Chitosan was found to be a favorable interface between bone and hydroxyapatite because it promoted an osteoconductive reaction.
Compliant footpad design analysis for a bio-inspired quadruped amphibious robot (2009)

A quadrupedal water runner robot inspired by the basilisk lizard has previously demonstrated the capability of water surface locomotion. Since the robot is aimed for the amphibious locomotion, a compatible design on both ground and water surface is discussed in this paper. A compliant footpad which can transfer elastic energy to propulsive momentum is introduced and modeled using a pseudo-rigid-body model. Dynamic modeling of the footpad and the robot provides a criterion of efficient ground locomotion. For the water surface locomotion, drag force can be reduced by compliance of the footpad. The optimized design taking into account two locomotions is studied and analyzed for stability using the Poincare map.

Impact of Site-Specific Bioconjugation on the Interfacial Activity of a Protein Biosurfactant (2019)

Biosurfactants are surface active molecules that can be produced by renewable, industrially scalable biologic processes. DAMP4, a designer biosurfactant, enables the modification of interfaces via genetic or chemical fusion to functional moieties. However, bioconjugation of addressable amines introduces heterogeneity that limits the precision of functionalization as well as the resolution of interfacial characterization. Here, we designed DAMP4 variants with cysteine point mutations to allow for site-specific bioconjugation. The DAMP4 variants were shown to retain the structural stability and interfacial activity characteristic of the parent molecule, while permitting efficient and specific conjugation of polyethylene glycol (PEG). PEGylation results in a considerable reduction on the interfacial activity of both single and double mutants. Comparison of conjugates with one or two conjugation sites shows that both the number of conjugates as well as the mass of conjugated material impact the interfacial activity of DAMP4. As a result, the ability of DAMP4 variants with multiple PEG conjugates to impart colloidal stability on peptide-stabilized emulsions is reduced. We suggest that this is due to steric constraints on the structures of amphiphilic helices at the interface. Specific and efficient bioconjugation permits the exploration and investigation of the interfacial properties of designer protein biosurfactants with molecular precision. Our findings should therefore inform the design and modification of biosurfactants for their increasing use in industrial processes and nutritional and pharmaceutical formulations.
Trigger Fingers Requiring Simultaneous Division of the A1 Pulley and the Proximal Part of the A2 Pulley (2007)

In a prospective study of 50 adult patients with primary idiopathic trigger finger, four patients (8%) required simultaneous division of the proximal 3 to 4 mm of the A2 pulley as well as the A1 pulley in order to completely resolve the triggering. At final follow up at 6 to 12 months, all patients were symptom-free with a full range of motion of the fingers. This entity is discussed.

Effect of host egg age on preference, development and arrestment of Telenomus remus (Hymenoptera: Scelionidae) (2012)

Age of host eggs can be a limiting factor for egg parasitoids. It is expected that old eggs are less preferred by egg parasitoids, which can discriminate between eggs of different ages by using chemical cues. The objective of this study was to determine the preference, development and arrestment of Telenomus remus Nixon (Hymenoptera: Scelionidae) parasitizing Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) eggs of different ages. This egg parasitoid preferred to parasitize 1- and 2-day-old eggs rather than 3-day-old eggs in choice and no-choice assays. However, although the percentage emergence of parasitoids is significantly lower from 2- and 3-day-old eggs, the sex ratio and developmental time are unaffected. Parasitoids spent longer searching substrates impregnated with extracts of 1- and 2-day old eggs than 3-day-old eggs. Our results reveal that T. remus is able to distinguish the most suitable (1-day-old) from the least suitable (3-day-old) host eggs, but unable to recognize the unsuitability of intermediate aged eggs. Egg arrestants may be responsible for the preference of T. remus for ovipositing in 1- and 2-day old eggs.
Notch enhances Ca2+ entry by activating calcium-sensing receptors and inhibiting voltage-gated K+ channels (2020)

The increase in cytosolic Ca<sup>2+</sup> concentration ([Ca<sup>2+</sup>]<sub>cyt</sub>) and upregulation of calcium-sensing receptor (CaSR) and stromal interaction molecule 2 (STIM2) along with inhibition of voltage-gated K<sup>+</sup> (K<sub>V</sub>) channels in pulmonary arterial smooth muscle cells (PASMC) have been implicated in the development of pulmonary arterial hypertension; however, the precise upstream mechanisms remain elusive. Activation of CaSR, a G protein-coupled receptor (GPCR), results in Ca<sup>2+</sup> release from the endoplasmic/sarcoplasmic reticulum (ER/SR) and Ca<sup>2+</sup> influx through receptor-operated and store-operated Ca<sup>2+</sup> channels (SOC). Upon Ca<sup>2+</sup> depletion from the SR, STIM forms clusters to mediate store-operated Ca<sup>2+</sup> entry. Activity of K<sub>V</sub> channels, like KCNA5/K<sub>V</sub>1.5 and KCNA2/K<sub>V</sub>1.2, contributes to regulating membrane potential, and inhibition of K<sub>V</sub> channels results in membrane depolarization that increases [Ca<sup>2+</sup>]<sub>cyt</sub> by opening voltage-dependent Ca<sup>2+</sup> channels. In this study, we show that activation of Notch by its ligand Jag-1 promotes the clustering of STIM2, and clustered STIM2 subsequently enhances the CaSR-induced Ca<sup>2+</sup> influx through SOC channels. Extracellular Ca<sup>2+</sup>-mediated activation of CaSR increases [Ca<sup>2+</sup>]<sub>cyt</sub> in <i>CASR</i>-transfected HEK293 cells. Treatment of <i>CASR</i>-transfected cells with Jag-1 further enhances CaSR-mediated increase in [Ca<sup>2+</sup>]<sub>cyt</sub>. Moreover, CaSR-mediated increase in [Ca<sup>2+</sup>]<sub>cyt</sub> was significantly augmented in cells co-transfected with <i>CASR</i> and <i>STIM2</i>. CaSR activation results in STIM2 clustering in <i>CASR/STIM2</i>-cotransfected cells. Notch activation also induces significant clustering of STIM2. Furthermore, activation of Notch attenuates whole cell K<sup>+</sup> currents in <i>KCNA5</i>- and <i>KCNA2</i>-transfected cells. Together, these results suggest that Notch activation enhances CaSR-mediated increases in [Ca<sup>2+</sup>]<sub>cyt</sub> by enhancing store-operated Ca<sup>2+</sup> entry and inhibits KCNA5/K<sub>V</sub>1.5 and KCNA2/K<sub>V</sub>1.2, ultimately leading to voltage-activated Ca<sup>2+</sup> entry.
Sensitivities of directional electromagnetic measurements for well placement and formation evaluation while drilling (2006)

We present sensitivities of first generation of directional loggin‐while‐drilling electromagnetic measurements using tilted and tasverse antenae technology. These measurements are primarily used for pro‐active geosteering, to determine the wellbore position with respect to geological boundaries. They can also be used for enhanced formation evaluation. A novel tool layout with symmetric transmitter‐receiver arrangement is implemented. This configuration enabled removal or amplification of sensitivities to dip, anisotropy and nearby boundaries, resulting in simplified responses and interpretation. In addition, we present how these measurement can be used for determination of structural dip, resistivity anisotropy at any angle, as well as detection fractures and their orientations. Measurement specifics for LWD applications and their relationship to conventional 3D induction couplings are discussed.
High-Voltage 4H-SiC PiN Diodes With Etched Junction Termination Extension (2009)

Implantation-free mesa-etched 4H-SiC PiN diodes with a near-ideal breakdown voltage of 4.3 kV (about 80% of the theoretical value) were fabricated, measured, and analyzed by device simulation and optical imaging measurements at breakdown. The key step in achieving a high breakdown voltage is a controlled etching into the epitaxially grown p-doped anode layer to reach an optimum dopant dose of ~ 1.2 times 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">13</sup> cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-2</sup> in the junction termination extension (JTE). Electroluminescence revealed a localized avalanche breakdown that is in good agreement with device simulation. A comparison of diodes with single- and double-zone etched JTEs shows a higher breakdown voltage and a less sensitivity to varying processing conditions for diodes with a two-zone JTE.

A newly recognized entity: intraductal “oncocytic” papillary neoplasm of the pancreas (1998)

Intraductal papillary-mucinous tumors of the pancreas are increasingly recognized, and their characteristic endoscopic and radiological features are well reported in the literature in recent years. Oncocytic features in these tumors are uncommon and unrecognized. Intraductal oncocytic papillary neoplasm is a distinct pancreatic tumor and is a recently recognized entity. We report a case of a 69-yr-old patient who presented with symptoms mimicking pancreatitis, resulting in delay in the diagnosis of her pancreatic tumor. She underwent a successful Whipple's procedure and subsequently has remained well. The resected specimen showed an intraductal oncocytic papillary-mucinous neoplasm. The entity is new and the literature information is inadequate at present to judge the biological behavior of this tumor. We discuss this recently recognized entity.
A Multilevel Inverter Topology With an Improved Reliability and a Reduced Number of Components (2021)

The reliabilities of the renewable energy source systems are affected by their inverter structures. So, an inverter topology with higher reliability reduces the maintenance cost of the system. In this article, a multilevel inverter structure is proposed with improved reliability and reduced component count. The proposed structure produces 7 and 11 voltage levels in symmetrical and asymmetrical configurations, respectively. This inverter topology utilizes six unidirectional switches and one bidirectional switch. The proposed inverter structure can be extended to generate any number of voltage levels with the inherent property of producing both positive and negative voltage levels. Various comparisons including the total number of switches, the total number of switch drivers, and the total blocking voltage are done to show the effectiveness of the proposed structure in the reduction of the component counts. In addition, the reliability of the proposed structure is analyzed and comparisons with other counterpart structures are studied. The comparison results show the reliability improvement of the proposed inverter structure. Finally, the simulation results, extracted by MATLAB/Simulink, and the experimental results, obtained from a laboratory prototype, are provided to prove the feasibility of the proposed multilevel inverter (PMI) structure.

Selected Issues on Electromagnetic Standardization of Soil Moisture (2022)

A large number of electromagnetic sensors for measuring soil moisture available on the market, differing in their method of measurement, price, shape, measurement volume, durability, etc., mislead the potential user. They cannot compare the right measurement equipment because there is no easy and reliable way to do so. The response of the sensors depends on the measurement frequency used, soil salinity, density, and texture, just to name a few. The growing concern for the sustainable use of water resources for agricultural, industrial, and domestic purposes and the growing market for the right measuring tools are putting pressure on users making the right choice. The article presents the issues and efforts of working towards standardization of electromagnetic measurements of soil moisture, especially in the field of the selection of measurement methods and reference materials that would enable the comparison of the performance of dielectric sensors available on the market. Work on the standardization of electromagnetic soil moisture measurements requires the cooperation of an interdisciplinary group of scientists and producers. The work done so far is an initial attempt to synchronize research in some international laboratories, learn about mutual research methods, and formulate research tasks for the future. Key questions about the concept development process leading to standard testing and evaluation practices for electromagnetic soil moisture measurements are still unanswered.

Cross-reactivity of SARS-CoV structural protein antibodies against SARS-CoV-2 (2021)

In the ongoing coronavirus disease 2019 (COVID-19) pandemic, there remain unanswered questions regarding the nature and significance of the humoral immune response toward other coronavirus infections. Here, we investigate the cross-reactivity of antibodies raised against the first severe acute respiratory syndrome coronavirus (SARS-CoV) for their reactivity toward SARS-CoV-2. We extensively characterize a selection of 10 antibodies covering all of the SARS-CoV structural proteins: spike, membrane, nucleocapsid, and envelope. Although nearly all of the examined SARS-CoV antibodies display some level of reactivity to SARS-CoV-2, we find only partial cross-neutralization for the spike antibodies. The implications of our work are two-fold. First, we establish a set of antibodies with known reactivity to both SARS-CoV and SARS-CoV-2, which will allow further study of both viruses. Second, we provide empirical evidence of the high propensity for antibody cross-reactivity between distinct strains of human coronaviruses, which is critical information for designing diagnostic and vaccine strategies for COVID-19.
