In-depth knowledge of the low-temperature hydrothermal synthesis of nanocrystalline hydroxyapatite from waste green mussel shell ( Perna Viridis ) (2023)

<b>ABSTRACT</b>This study presents the use of a low-temperature hydrothermal method for extracting calcium sources from green mussel shell (<i>P. Viridis</i>) wastes and converting them into synthetic nanosized hydroxyapatite (HA). In this study, raw mussel shells were washed, pulverised, and sieved to start producing a fine calcium carbonate-rich powder. XRD quantitative analysis confirmed that the powder contains 97.6 wt. % aragonite. This powder was then calcined for 5 h at 900 °C to remove water, salt, and mud, yielding a calcium-rich feedstock with major minerals of calcite (68.7 wt.%), portlandite (24.7 wt.%), and minor aragonite (6.5 wt.%). The calcined powders were dissolved in aqueous stock solutions of HNO<sub>3</sub> and NH<sub>4</sub>OH before hydrothermally reacting with phosphoric acid [(NH<sub>4</sub>)<sub>2</sub>HPO<sub>4</sub>], yielding pure, nanoscale (16-18 nm) carbonated HA crystals, according to XRD, FT-IR, and SEM analyses. The use of a low-temperature hydrothermal method for a feedstock powder produced by the calcination of low-cost mussel shell wastes would be a valuable processing approach for the industry's development of large-scale hydroxyapatite nanoparticle production.
Neighborhood sequences in the diamond grid: Algorithms with two and three neighbors (2009)

Abstract In the digital image processing, digital distances are useful; distances based on neighborhood sequences are widely used. In this article, the diamond grid is considered, that is, the three‐dimensional grid of carbon atoms in the diamond crystal. An algorithm to compute a shortest path defined by a neighborhood sequence between any two points in the diamond grid is presented. A formula to compute the distance based on neighborhood sequences with two neighborhood relations is given. The metric and nonmetric properties of some distances based on neighborhood sequences are also discussed. Finally, the constrained distance transformation is shown. © 2009 Wiley Periodicals, Inc.

P3‐326: Blood‐brain barrier permeable hsp90 inhibitor reduces soluble tau burden and rescues tau‐dependent phenotype in a mouse model of tau accumulation (2015)

Current Alzheimer's disease (AD) medications attempt to address the symptoms associated with this disorder. However, there are no FDA approved AD medications which can act on the biochemical mechanisms which drive toxic pathology including tau (MAPT, tau) accumulation. Toxic tau species are a hallmark AD pathology and are also the primary pathogenic species in a collection of neurodegenerative disorders, similar to AD, described as “tauopathies.” In these disorders, tau accumulation is associated with abnormal phosphorylation progressing to a state of hyperphosphorylation. One avenue for treatment is the inhibition of the 90kDa heat shock protein (Hsp90); a molecular chaperone found to be involved in the formation of neurotoxic species of the microtubule associated protein tau. Normally, aberrant protein accumulation is regulated by the molecular chaperones. However, AD presents a disease-specific population of Hsp90; a population which preserves disease driving tau accumulation. We present data obtained through in vivo studies utilizing a mouse model of tau accumulation (PS19, P301S tau) treated with a blood-brain barrier permeable Hsp90 inhibitor designed by our lab. Hsp90 inhibition capably reduces tau species associated with neurotoxicity & ameliorates strain-specific tau-related phenotypes. Mice treated display no signs of toxicity; confirmed through pathology analysis following chronic administration. The inhibition of Hsp90 induced the expression of the pro-survival chaperone Hsp70, a chaperone also associated with tau degradation. Additionally, inhibiting the Hsp90-dependent protection of tau abrogated a terminal tau-driven phenotype thereby extending the lives of treated animals as compared to transgenic animals receiving vehicle or no treatment. Together, these findings demonstrate the potential for Hsp90 inhibition in the treatment of neurodegenerative diseases involving tau accumulation; namely, Alzheimer's disease. Data accompanying this presentation which presents experimental behavioral changes and immunohistochemical analysis of neural tau burden can be seen on the poster presented by Inda, C. et al.
Darstellung von Penisgefäßanastomosen mittels farbkodierter Doppler-Sonographie: Vergleich mit CW-Dopplersonographie und Klinik (2008)

In fourteen patients undergoing surgical revascularization (11 with Hauri's, three with Virag's anastomosis) because of erectile dysfunction, the patency of vascular anastomosis was evaluated and visualized by color-coded-Doppler sonography (CCDS). Results were compared with continuous-wave Doppler (CWD) and clinical data. CCDS proved to be superior to CWD with regard to assessment of flow in the penile vessels and to applicability. Strength and direction of flow can be judged visually. Therefore, the nature of the imaged vessel (artery or vein, deep or dorsal artery) can be differentiated. There is a good correlation of CCDS and CWD in their evaluation of the patency of the anastomosis. CCDS showed higher accuracy in detecting deep cavernosal arteries.
Reexamination of Josephson junctions coupled to transmission lines (2008)

The effect of dissipation when due to the load of a transmission line coupled to a Josephson junction is reconsidered and evaluated by means of a simple direct procedure that supplies analytical expressions. The results are in good agreement with the ones previously reported in the literature. A simple criterion for testing experimental results is introduced.
Experimental Evidence for a Cochlear Source of the Precedence Effect (2013)

The precedence effect (PE) refers to the dominance of directional information carried by a direct sound (lead) over the spatial information contained in its multiple reflections (lags) in sound localization. Although the processes underlying the PE have been largely investigated, the extent to which peripheral versus central auditory processes contribute to this perceptual phenomenon has remained unclear. The present study investigated the contribution of peripheral processing to the PE through a comparison of physiological and psychoacoustical data in the same human listeners. The psychoacoustical experiments, comprising a fusion task, an interaural time difference detection task and a lateralization task, demonstrated a time range from 1 to 4.6-5 ms, in which the PE operated (precedence window). Click-evoked otoacoustic emissions (CEOAEs) were recorded in both ears to investigate the lead-lag interactions at the level of the basilar membrane (BM) in the cochlea. The CEOAE-derived peripheral and monaural lag suppression was largest for ICIs of 1-4 ms. Auditory-evoked brainstem responses (ABRs) were used to investigate monaural and binaural lag suppression at the brainstem level. The responses to monaural stimulation reflected the peripheral lag suppression observed in the CEOAE results, while the binaural brainstem responses did not show any substantial contribution of binaural processes to monaural lag suppression. The results demonstrated that the lag suppression occurring at the BM in a time range from 1 to 4 ms, as indicated by the suppression of the lag-CEOAE, was the source of the reduction in the lag-ABRs and a possible peripheral contributor to the PE for click stimuli.
Donor age and cell passage affects differentiation potential of murine bone marrow-derived stem cells (2008)

Both increasing age and the number of passages have lineage dependent effects on BMSC differentiation potential. Furthermore, there is an obvious interplay between donor age and cell passage that in the future must be accounted for when developing cell-based therapies for clinical use.
New Family of Zero-Voltage-Transition PWM Bidirectional Converters With Coupled Inductors (2011)

In this paper, a new family of zero-voltage-transition bidirectional converters using coupled inductors is introduced. By applying two auxiliary switches and coupled inductors, soft-switching condition is achieved for all semiconductor elements regardless of the power flow direction. Moreover, the presence of coupled inductors provides significant reduction in the converter volume, since all the converter inductors are implemented on a single core. Also, all semiconductor elements benefit from soft-switching condition in full duty cycle range, and thus, high efficiency is achieved for full line voltage range. No extra voltage and current stresses on the main switches and the ease of control are the other properties of the proposed converters. The proposed bidirectional buck and boost converter is fully analyzed for both buck and boost operating modes. The validity of the theoretical analysis is justified using the experimental results of a 240-W 50-100-V prototype converter.
A physical mechanism of current-induced resistance decrease in heavily doped polysilicon resistors (1982)

A physical model describing the basic mechanism of the current-induced resistance decrease in heavily doped polysilicon resistors' experimental aspects reported in the previous paper [1], is proposed. The resistance decrease is explained in terms of the local melting of boundary layers between crystal grains in the polysilicon caused by the current feeding and a segregation of impurity atoms in the subsequent solidification process. This model explains all the experimental results concerning the resistance decrease phenomena. The theoretical expression for the current dependence of resistance decrease derived from the model agrees well with the experimental characteristics.
Evolution and structural diversification ofNictaba-like lectin genes in food crops with a focus on soybean (Glycine max) (2016)

Taken together, the comparative genomics data contributes to our understanding of the Nictaba -like gene family in species for which the occurrence of Nictaba domains had not yet been investigated. Given the ubiquitous nature of these genes, they have probably acquired new functions over time and are expected to take on various roles in plant development and defence.
Reducing search by partitioning the word network (1989)

This paper proposes an architecture for integrating speech recognition and natural language processing to provide a spoken language understanding system. This work, done in collaboration with the MIT Spoken Language Systems Group, has enabled us to interface our Pundit natural language processing system [Dahl1987, Palmer1986, Hirschman1982, Hirschman1986, Dowding1987] and SUMMIT, the MIT speech recognition system[Zue1989, Glass1988, Seneff1985, Zue1985]. Information is passed between the two systems using the <i>Word Network</i> (or <i>Word Lattice</i>) which is a set of word-score pairs together with the start and end points for each word. The word network is organized as a directed acyclic graph, whose arcs are labeled as word-score pairs, and whose nodes are moments in time. The recognition problem is to find the best scoring grammatical sequence of words from the graph's begin-point to its end. In our experments, we analyzed word networks from the TIMIT domain and the Resource Management domain, constructed without using any language model.
Measured Diffusion Capacity versus Prediction Equation Estimates in Blacks without Lung Disease (2004)

Current PEE for DLCO when used in healthy blacks can result in an abnormal reading in up to 50% or more of the time. This failure of the PEE is related to a reduction in lung volume in African-Americans that is not accounted for. One approach to overcome this problem, until separate PEE are developed in blacks, is to race correct the Miller PEE for diffusion by 12%. This reduces the DL(CO) error to less than 5% for this population.
Oncometabolite Fingerprinting Using Fluorescent Single‐Walled Carbon Nanotubes (Adv. Mater. Interfaces 4/2022) (2022)

Oncometabolite Fingerprinting In article number 2101591, Dean Amir, Gili Bisker, and co-workers use DNA-functionalized single-walled carbon nanotubes (SWCNTs) for the recognition and quantification of the oncometabolite D-2-hydroxyglutarate (D2HG). The DNA-SWCNT sensors can distinguish D2HG from closely-related metabolites, including the enantiomer L-2-hydroxyglutarate, owing to measurable modulations of the near-infrared fluorescence of the SWCNT. These nanosensors open new opportunities for the advancement of cancer research.
Early Outcomes of Anterior Cervical Discectomy and Fusion Using a Porous PEEK Interbody Fusion Device (2018)

Background: Recently, porous surface polyether-etherketone (PEEK) implants have been developed to interact with adjacent endplates. Our goal was to evaluate the efficacy of novel high-strength, porous PEEK interbody fusion devices for anterior cervical discectomy and fusion (ACDF) in patients with symptomatic single-level and multilevel degenerative cervical disc disease at 1 year. Methods: Fifty consecutive patients (31 women, 19 men; average age, 60 years) with degenerative cervical disc disease underwent ACDF using a porous PEEK interbody implant and plate. There were 11 1-level; 23 2-level, and 16 3-level fusions between C3 and C7. Patients were assessed at 1.5, 3, 6, and 12 months. Standardized outcome measures were used to evaluate the patient’s condition before and after surgery. Plain radiographs were used to assess fusion, bony in-growth, subsidence, and implant migration. Sagittal plane angulation was measured on neutral lateral radiographs and determined by Cobb’s criteria. Intradiscal distraction and subsidence were measured by assessing the vertical distance between the midpoints of the adjacent vertebral endplates. Results: At 12 months after surgery, all patients showed improvement in Oswestry Neck Disability Index and neck and arm pain scores. Similarly, at 12 months, all patients showed radiographic fusion. No patient demonstrated motion across the interspace on flexion-extension lateral radiographs. Sagittal plane angulation improved to an average of -6° (range, -2° to -8°) with no measurable evidence of implant migration or subsidence. Average disc space height increased more than 4 mm. No patient had measurable radiographic evidence of a pseudarthrosis or halo formation around the implant. Conclusion: One-year results in this prospective nonrandomized study show that porous-surface PEEK is a clinically viable alternative for improving osseointegration and fusion rates of interbody implants to treat degenerative cervical disc disease.

[Genetic counseling versus genetic self testing: what challenges?]. (2001)

The development of molecular genetics allows us to have access to an increasing number of informations on our own genetic code. This leads to a new form of medical activity, called predictive and preclinical medicine. It involves significant ethical stakes in terms of individual information and consent for the test as well as in terms of support for the patient which is summarized by the concept of "genetic council". The self-test, which bypasses this medical supervision, represents, for the patient becoming a consumer, a threat from the emotional point of view as well as from a social perspective (insurance, access to the working market). This analysis shows that the only real driving force for the development of the genetic self-test is commercial. To resist what is sometimes called "genetic shopping" one must consider an ethical, deontological and social priority.
Toward an Action Based Metaphor for Gestural Interaction with Musical Contents (2009)

Technology-mediated music access is more and more becoming an interactive process, involving non-linguistic communication and action-based modalities. A better understanding of the musical experience and how this experience can be described is a crucial issue to render more effective and natural the interaction with musical contents. This paper aims at verifying if and how non-linguistic descriptors can be related to musical stimuli and their expressive cues. We designed four experiments using two sets of musical stimuli (simple and complex) and two sets of non-linguistic descriptors (acoustic and haptic), that we called attractors. In particular, the haptic attractors simulate the mechanic concepts of friction, elasticity and inertia (FEI). The results showed that subjects are able to relate musical stimuli with both acoustic and haptic attractors, even if the FEI metaphor seems to be more suitable for describing expressive cues in simple musical excerpts, where the expressive content is mainly related to performance cues, than in complex musical stimuli, where musical structure is more relevant.

Elderly friendliness evaluation of mobile assistants (2017)

The rapidly increasing elderly population in many developed and developing countries poses great challenges to elderly care systems. To alleviate the problem of a shrinking workforce to deliver elderly care, using mobile intelligent assistants to lessen the caregivers' workload becomes a promising solution. However, the friendliness of such mobile assistants, which is seldom measured in a quantitative manner, may hinder their acceptance by the elderly users. In this paper, we propose a formalized systematic approach named Elderly Friendliness Evaluation Methodology (EFEM) to measure the elderly friendliness of any product, service or system. Furthermore, we apply EFEM to evaluate the elderly friendliness of five commercial mobile assistants and three prototypes. The comparison results show that the commercial assistants are less elderly-friendly than the prototypes. The high Elderly Friendliness Scores (EFSs) achieved by the prototypes suggest that they are highly likely to be well accepted by elderly users.
Preclinical Evaluation of the Pharmacokinetics, Biodistribution, and Elimination of MS-325, a Blood Pool Agent for Magnetic Resonance Imaging (1997)

Modeling of Combined Temperature Cycling and Vibration Loading on PBGA Solder Joints Using an Incremental Damage Superposition Approach (2008)

Concurrent vibration and temperature cycle environments are commonly encountered in the service life of many electronic products, particularly those used in automotive, avionic, and military applications. However, the ability to predict life expectancy under these types of environments remains a technical challenge. In this paper, a traditional linear damage superposition modeling approach and a damage superposition approach that considers the temperature imposed load state on vibration damage are compared with experimental test results for plastic ball grid array (PBGA) assemblies subjected to temperature cycling, vibration loading, and combined temperature cycling and vibration loading conditions. The results showed much earlier PBGA solder-joint failure under combined loading than with either separate temperature cycling or room temperature vibration loading. Traditional linear superposition was found to over-predict the solder-joint fatigue life, since it neglects the interaction effects of two different loadings. The damage superposition approach that considers the temperature imposed load state on vibration damage is found to be more representative of test data.

Distribution and penetration of reactive oxygen and nitrogen species through a tissue phantom after Plasma Gun treatment (2019)

The transport and distribution phenomena of reactive oxygen and nitrogen species (RONS) into biological tissue following non-thermal plasma treatment have received much attention. The aim of this study is to test the efficacy of Plasma Gun (PG) on transporting the reactive species in an agar composed tissue phantom. RONS are generated on the agar gel by the plasma treatment and they continue to spread in the depth after plasma exposure. The amount of RONS after passing through the tissue phantom are strongly depending on discharge parameters such as distance to the target and capillary shape.
