Efficacy of alginate and chickpea protein polymeric matrices in encapsulating curcumin for improved stability, sustained release and bioaccessibility (2023)

The present study compares the ubiquitously used alginate with seldom used chickpea protein as matrices for encapsulating curcumin, in terms of stability, in vitro release and bioaccessibility. Alginate and chickpea protein particles prepared via ionic gelation and isoelectric precipitation methods, respectively, were in the submicron range showing high encapsulation efficiencies of above 90%. Encapsulated particles stored in dark refrigerated conditions displayed greater stability of curcumin. In vitro release of curcumin from both encapsulated particles exhibited pH-dependent slow controlled release. However, alginate particles were more promising due to a protective role performed at gastric pH. The release profiles of curcumin from alginate and chickpea protein particles were best described by First order and Weibull models at pH 2 respectively, while those were well described by Higuchi and Zero order models at pH 6.8 respectively. Accordingly, release of curcumin from both encapsulated particles displayed diffusional controlled release at pH 2 while that from both particles showed diffusion-swelling controlled release at pH 6.8. Bioaccessibility of curcumin from both matrices after intestinal digestion was around 50% while that of free curcumin was approximately 18%. Overall, results point to alginate having an advantage over the chickpea protein matrix for safe efficacious oral delivery of curcumin. Thus, encapsulation of curcumin in alginate may be a promising method for the engineering of curcumin incorporated food with enhanced properties.
An input-output model for the gerbil cochlea (2002)

Signal processing in individual channels of the auditory periphery are modelled based on I/O data. Each channel comprises the outer and middle ear apparatus in cascade with a single cochlear filter served by several cochlear afferent nerve fibers. The input is an auditory stimulus and the output is a sequence of neural spike events recorded from cochlear afferent nerve fibers. Tuning properties of the cochlear filter are identified. The channel is modelled as a linear dynamical system in cascade with a memoryless nonlinearity (a Wiener system), followed by an additional element which generates Poisson distributed spike events. We show that the Poisson block can be replaced by an additive noise term. Thus we can consider the more general problem of Wiener identification with output noise, and simplify the analysis of the identification. The impulse response of the linear system shows increased damping and broadened frequency spectrum as stimulus amplitude is increased. By modulating the rms input amplitude and strobing the I/O data during estimation, we study dynamical changes in the linear system's tuning properties. We thus show that changes in the cochlear channel's linear response occur rapidly and reversibly as a function of the rms input amplitude. Our results suggest that a good I/O model for the cochlear channel might consist of a family of Wiener-Poisson models, parameterized by the rms input amplitude.
Accurate quantitative phase imaging using generalized phase contrast (2008)

The generalized phase contrast (GPC) method is explored for improving the accuracy in quantitative reconstruction of two-dimensional phase distribution from images of semi-transparent objects viewed with a common-path interferometer (CPI). We propose a novel optical scheme for highly accurate determination of the object-dependent complex synthetic reference wave (SRW) in a CPI. Using a simple 4f imaging optical setup, GPC provides an analytic model of the SRW profile that is shown here to increase phase measurement accuracy over the entire output aperture. The improved accuracy due to the GPC model can exceed one order of magnitude compared to that of the conventional plane wave model of the reference beam. Furthermore, we describe a novel method for accurate derivation of the strength of the phase object's zero spatial frequency component based on the intensity of the traditionally ignored halo region encompassing the interferogram. Combining this information with three inteferometric measurements, full-field phase images with unconstrained phase strokes are obtained accurately.
Effect of heartworm disease and heartworm-associated respiratory disease (HARD) on the right ventricle of cats (2017)

Dirofilaria immitis infection occurs in dogs and cats, both of which species are clinically affected by mature adult infections. Cats are uniquely affected by immature-adult infections with an inflammatory pulmonary disease called Heartworm-Associated Respiratory Disease (HARD). D. immitis infection causes pulmonary parenchymal and vascular pathology in the dog and cat. Dogs develop pulmonary hypertension and cor pulmonale, whereas the development of pulmonary hypertension is rare in the cat. D. immitis infection in the dog causes alteration of the right ventricular (RV) extracellular matrix, including a decrease in myocardial collagen. In this study, the RV myocardial changes of cats infected with adult and immature-adult D. immitis were assessed. The cardiopulmonary systems of six groups of SPF cats (n = 9-10 per group) were examined 8 or 18 months after infection with L3 D. immitis. Two groups were untreated and allowed to develop adult HW; two groups were treated with ivermectin starting 3 months post infection, thus allowing HARD but no mature adult heartworms; and two groups were treated with selamectin beginning 1 month post infection, preventing development of L5 or adult heartworms. A group of specific pathogen free (SPF) normal cats was utilized as a negative control (n = 12). Lung pathologic lesions were objectively assessed, and both RV and left ventricular (LV) weights were obtained to calculate an RV/LV ratio. Intramural RV myocardial collagen content was quantitatively assessed. RV/LV weight ratios were not different between groups. Negative control cats had significantly greater RV collagen content than all other affected groups (P = 0.032). Analysis of the RV/LV ratios and collagen content revealed no significant relationship (r = 0.03, P = 0.723, respectively). Collagen content had a modest, but significant, negative correlation, however, with both pulmonary vascular pathology (r = −0.25, P = 0.032) as well as the total pulmonary parenchymal and vascular pathology (r = −0.26, P = 0.025). Cats infected with mature and immature D. immitis did not develop RV hypertrophy but did demonstrate loss of RV myocardial collagen content. The collagen loss was present at 8 and 18 months after infection in all infected cats. This loss of RV myocardial collagen was correlated with the severity of pulmonary parenchymal and vascular pathology.

TRANSIENT BEHAVIOR OF THE ELECTROMOTIVE FORCE OF AN OXYGEN SENSOR INDUCED BY THE TEMPERATURE CHANGE (1984)

Abstract When the operating temperature of an oxygen sensor with a zirconia-based electrolyte was changed rapidly during the measurement of the oxygen partial pressure in argon, an abnormal electromotive force was transiently generated. This phenomenon is attributed to the transient variation of oxygen concentrations at the electrolyte/electrode interfaces.
The design of efficient broad-band piezoelectric transducers (1978)

A design method for acoustic thin disk transducers with high efficiency, broad bandwidth, and good impulse response is presented. This method is based on the use of quarter-wave matching layers between the piezoelectric material and the acoustic load. As is made evident using the transmission line model of Krimholtz, Leedom, and Matthaei, the finite thickness of the piezoelectric material must be taken into account in the matching layer design. Criteria for optimum broad-band transducer designs with a given piezoelectric material are developed which show the importance of a high electromechanical coupling coefficient. A method for obtaining Gaussian shaped passbands, necessary for optimum impulse response, is also shown. Several transducers have been built to illustrate this design approach with excellent agreement between theory and experiment. One such transducer has 3.2 dB round trip insertion loss and one octave bandwidth.
Noninvasive Transcutaneous Oxygen Monitoring, A Review (1981)

Clinical results using the heated PtcO2 sensor are presented that verify the clinical usefulness of the device for monitoring trends in arterial PaO2 non-invasively and on a continuous basis. Monitoring of local perfusion with the PtcO2 sensor is also discussed.
Noise-adaptive spatio-temporal filter for real-time noise removal in low light level images (2005)

Noise reduction gradually becomes one of the most important features in consumer cameras. The video signal is easily interfered by noise during acquisition process especially in low light environment. Many of the state-of-the-art filters for noise reduction perform-well for high contrast images. However, for low light images, the filter performance degrades seriously. In this paper, we propose a noise-adaptive spatio-temporal (NAST) filtering for removal of noise in low light level images. The proposed algorithm consists of a statistical domain temporal filter (SDTF) for moving area and a spatial hybrid filter (SHF) for stationary area. By minimizing required resources for implementation, we present a high quality, low-cost noise reduction filter for low light images. Since the proposed algorithm is designed for real-time implementation, it can be used as a pre-filter for a DCT-based encoder to enhance the coding efficiency of many commercial applications such as low cost camcorders, digital cameras, CCTV, and surveillance video systems.
Real-Time Vibronic Coupling Dynamics in a Prototypical Conjugated Oligomer (1999)

Phonon modes which are strongly coupled to the lowest optical transition of $\ensuremath{\alpha}$-sexithienyl are directly probed in real time by coherent vibrational spectroscopy. The resonant excitation source is a tunable 10-fs optical parametric amplifier. We identify five strongly coupled phonon modes at ${\ensuremath{\omega}}_{1}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}112{\mathrm{cm}}^{\ensuremath{-}1}$, ${\ensuremath{\omega}}_{2}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}299{\mathrm{cm}}^{\ensuremath{-}1}$, ${\ensuremath{\omega}}_{3}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}702{\mathrm{cm}}^{\ensuremath{-}1}$, ${\ensuremath{\omega}}_{4}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1040{\mathrm{cm}}^{\ensuremath{-}1}$, and ${\ensuremath{\omega}}_{5}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1454{\mathrm{cm}}^{\ensuremath{-}1}$. Vibrational dephasing times are measured to be between 0.4 and 3 ps. We gain direct hints on potential energy anharmonicity by measuring the transient vibrational frequency within the first ps.

Den oplanerade sjukhusvistelsens påverkan på personer med demens : - En systematisk litteraturstudie (2016)

Bakgrund: Demens är idag vår snabbast växande folkhälsosjukdom där personer som drabbas ofta vistas på sjukhus. Denna patientgrupp är sårbar då de många gånger inte kan uttrycka sig verbalt och är beroende av andra människors välvilja. Möten med patienter med demens kan därmed vara komplexa då dessa till stor del blir baserade på tolkning av deras kroppsspråk. Syfte: Syftet var att belysa hur en oplanerad sjukhusvistelse påverkar personer med måttlig till svår demenssjukdom. Metod: En systematisk litteraturstudie som utgörs av 12 vetenskapliga artiklar från databaserna Cinahl och PsycINFO där ett induktivt förhållningssätt tillämpades vid analysprocessen. Resultat: Resultatet sammanställdes utifrån tre kategorier med 14 underliggande koder. De tre kategorierna var: Försämrat välbefinnande, Bristande behovstillfredsställelse och Bristande etisk omvårdnad. Det framkom att faktorer som tidsbrist, kunskapsbrist tillsammans med en inadekvat sjukhusmiljö och verksamhet bidrog till att patienter med demens ofta påverkades negativt av en oplanerad sjukhusvistelse. Slutsats: Slutsatsen av vårt resultat påvisade att det fanns ett stort behov av utveckling inom organisationsuppbyggnaden och att utbildning kring omvårdnad av patienter med demens behövde utökas inom kontexten sjukhusmiljö.

REOPT V2.0. An Electronic Encyclopedia of Remedial Options (1992)

REOPT has been developed by Pacific Northwest Laboratory to provide information about remedial action technologies, including application and regulatory information for over 700 contaminants. REOPT is a user-friendly personal computer program and database that functions like an electronic encyclopedia, sorting and presenting information to quickly familiarize engineers and planners with available remediation technologies. The system will help users focus quickly on the remediation technologies most likely to be effective for a particular site and problem, and presents concise, easy-to-use information about those technologies, helping users identify the key factors and constraints to consider in evaluating the use of each technology. REOPT contains information on approximately 90 established (i.e., proven) remediation technologies that could potentially be used for DOE waste-site cleanup. REOPT also contains auxiliary information about hazardous and radioactive contaminants and the federal regulations that govern their disposal. REOPT contains data for approximately 90 remedial action technologies, divided into categories according to the portion of a remedial action (i.e., containment, treatment, disposal, etc.) that they relate to or perform. Technologies are also classified according to the contaminants to which they may be applied. Contaminants may be selected from a list of approximately 700 in ten organic and four inorganic categories.more » The information for each technology is organized into the broad categories of descriptive information, application information, and additional information sources; these are then subdivided to allow the user to access more specific information about the technology.« less

Initial Bacterial Adhesion and Biofilm Formation on Aligner Materials (2020)

The present study aims to assess the initial bacterial adhesion and biofilm formation on different aligner materials. A total of four different aligner materials, CA-medium (CAM), copolyester (COP), Duran (DUR), Erkodur (ERK), were tested. Stimulated human saliva was obtained from six healthy volunteers. Salivary bacteria were harvested by centrifugation, and 1 mL of the salivary suspension was injected onto each sample surface for 2 h and 3 days, respectively. The samples were then washed twice with 5 mL 0.9% NaCl solution, and non-adherent bacteria were removed. The adherent microorganisms were dislodged from the sample surfaces after ultrasonication for 4 min in 1 mL 0.9% NaCl on ice. After the incubation of the adherent salivary bacteria under both aerobic and anaerobic conditions on Columbia blood agar plates at 37 °C and 5% CO<sub>2</sub> and in anaerobic jars overnight, several dilutions thereof were used for the determination of CFUs. This protocol was applied three times, obtaining an average of nine independent measurements for each material group. Overall, the differences between the tested aligner materials as well as between the materials and controls were not of statistical significance (<i>p</i> > 0.05). Regarding initial bacterial attachment and biofilm formation, the tested aligner materials are comparable to enamel and metal orthodontic brackets and can be therefore considered for clinical use. The four tested aligner materials CAM, COP, DUR, ERK showed no significant differences in initial microbial attachment and biofilm formation of aerobic and anaerobic species compared to enamel and conventional brackets.

P2‐260: The neuroprotective functions of selenoprotein M and selenoprotein I (2010)

Cumulative oxidative damage is strongly implicated in neurological and neurodegenerative diseases Some members of the selenoprotein family, which contain the trace element selenium incorporated as selenocysteine, the 21st amino acid, have well-characterized antioxidant activities (i.e the glutathione peroxidases), but the functions of many of the 25 human selenoproteins are unknown. Studies involving mice which overexpress mutant presenilin-2, which causes a familial form of Alzheimer's disease, are deficient in brain selenoprotein M (SelM), an endoplasmic reticulum (ER)-associated protein. Additionally, the mutation also results in chronically altered ER-based calcium regulation, implicating a role for SelM in calcium homeostasis. The membrane-bound selenoprotein I (SelI) is a mammalian form of ethanolamine phosphotransferase involved in production of phosphatadyl ethanolamine, and may be important in neuronal growth and phospholipid signaling pathways. We investigated the neuroprotective function of SelM and SelI in primary neuron cultures as well as the murine hippocampal HT22 cell line and the cerebral astrocyte C8-D1A cell lines. We examined the function of these two selenoproteins by overexpression and knock-down in cell culture models. We induced oxidative stress with hydrogen peroxide and challenged cells with aggregated amyloid beta peptides. Oxidative stress and apoptosis were measured using TUNEL labeling, propidium iodide, flow cytometry, and calcium imaging. Our results confirm that SelM plays an important role in protecting the brain against oxidative damage as well as functioning in calcium regulation. SelM overexpression protects against toxicity caused by aggregated amyloid beta protein, increasing cell viability approximately 50 percent compared to control cells. SelI overexpression in neuronal and glial cell lines reduced levels of reactive oxygen species and apoptotic cell death. In addition cells overexpressing SelI had altered cytosolic calcium levels and calcium responses to oxidative stress. These results suggest that SelM and SelI are neuroprotective and reduce oxidative stress. A greater understanding of these, and other selenoproteins may provide future therapeutic applications which could be beneficial to our aging populations.
The Absorption of Sound in Oxygen as Influenced by the Presence of Other Gases (1934)

The authors recently have described experiments which show that the absorption of audible sound in oxygen is strongly influenced by the presence of water vapor. [J. Acous. Soc. (Oct., 1933).] The present work describes the effects produced when other gases are mixed with oxygen, such as He, H2, CO, CO2, NH3, H2S, CCl4, C2H5OH, C2H2, C6H6, and other hydrocarbons. Of these gases, all except CO and CO2 produced effects similar to that produced by water vapor, that is, as the concentration of the foreign gas was increased from zero the absorption coefficient m increased to a maximum and then decreased. In every instance the maximal value of m coincided with that previously obtained for oxygen and water vapor (10×10−4 cm−1 at 3000 cycles and 20×10−4 cm−1 at 6000 cycles), but the concentration at which the maximal absorption occurred was very largely dependent upon the kind of foreign gas mixed with the oxygen. Thus, a trace of C2H5OH was sufficient to give the maximal absorption, whereas concentrations of the order of 10 to 50 percent were required for such gases as H2 and He. For all admixed gases, with the exception of water vapor, the concentration at which the absorption is a maximum is proportional directly to the frequency.
Thin film CdTe homojunctions by MOCVD (solar cells) (2002)

Polycrystalline solar cell thin-films of cadmium telluride (CdTe) have been deposited on glass and SnO/sub 2/:F/glass substrates at 350 degrees -400 degrees C by the reaction of dimethylcadmium (DMCd) and diisopropyltellurium (DIPTe) in a hydrogen atmosphere. The DMCd/DIPTe molar ratio in the reaction mixture is an important factor, affecting the deposition rate, conductivity type, and the incorporation of dopants. The deposited films are p-type at a DMCd/DIPTe molar ratio of 0.6 or less and are n-type at higher ratios. Extrinsically doped CdTe films have been deposited for the first time by using ethyldimethylindium and arsine as the n- and p-type dopant, respectively. The electrical properties of undoped and doped CdTe films have been characterized. Thin-film CdTe homojunctions have been prepared by the successive in-situ deposition of extrinsically doped n- and p-CdTe films on SnO/sub 2/:F/glass substrates and their properties investigated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
