[Investigation of temperature sensitive liposome encapsulated adriamycin injected into hepatic artery for targeted behavior and cancer therapy]. (1991)

Temperature sensitive liposome entrapped adriamycin was injected into the hepatic artery of Wistar rats bearing implanted hepatic tumor. Two hours after the injection, the liver was heated to 42 degrees C and maintained at that temperature for 6 minutes using a local hyperthermia. The variation in the pattern of the concentration of the liposomal drug in circulation, and the drug distribution in tissues were investigated. Results indicated that adriamycin was released from the liposomes with the drug concentration peaking in circulation at 30 minutes after heating. Following the hyperthermia treatment, the total amount of drug in the liver decreased, while that in the tumor and urine increased. The 14C labeled liposome track test showed that a parallel relationship between the lipid and the drug was maintained for 8 hours after the hepatic injection, and physiological environment was a determinant of change and existence of liposomal carrier. However, the drug encapsulated in the liposomes can be controlled by hyperthermia to target the tumor. Therapeutic experiments showed that in the group treated with the hepatic artery-injected liposome plus hyperthermia control, the liver tumor growth of the rats administered at 7 days after W256 carcinosarcoma implantation on liver was notably inhibited and the life-span of the animal was greatly extended compared with those of aqueous administration groups and iv injected liposome group.
Weed Control and Crop Safety with Premixed Pyrasulfotole and Bromoxynil in Grain Sorghum (2013)

Field experiments were conducted in grain sorghum at five locations in Kansas in 2009 and 2010, to evaluate the efficacy and crop safety of early- to mid-POST (EMPOST) and late-POST (LPOST) applications of premixed pyrasulfotole and bromoxynil (PYRA&BROM) in tank mix combinations with atrazine or atrazine plus 2,4-D ester or dicamba compared to bromoxynil plus atrazine. PYRA&BROM at 244 or 300 g ai ha −1 plus atrazine at 560 g ai ha −1 applied EMPOST controlled pigweed species (Palmer amaranth, tumble pigweed, and redroot pigweed), kochia, velvetleaf, common sunflower, ivyleaf morningglory, and common lambsquarters 93% or greater. Puncturevine control among three locations ranged from 85 to 99%. Control of most weed species was not improved by increasing PYRA&BROM rate from 244 to 300 g ha −1 or by tank mixing 2,4-D or dicamba with PYRA&BROM plus atrazine. However, ivyleaf morningglory control was improved at the LPOST timing by adding 2,4-D or dicamba at 140 g ae ha −1 . In no instance did any PYRA&BROM treatment provide greater weed control than bromoxynil plus atrazine at 281 + 560 g ha −1 when applied EMPOST, but in most instances PYRA&BROM treatments were more effective than bromoxynil plus atrazine when applied LPOST. Generally, PYRA&BROM treatments were more effective when applied EMPOST than LPOST, especially when 2,4-D or dicamba was added. PYRA&BROM plus atrazine treatments caused foliar bleaching in sorghum within 7 ± 3 d after treatment, but recovery was complete within 3 to 4 wk and grain yields were not reduced. Tank mixing dicamba with PYRA&BROM and atrazine occasionally reduced visible crop response compared to PYRA&BROM plus atrazine. Our results indicate that PYRA&BROM plus atrazine with or without 2,4-D or dicamba selectively controls several troublesome broadleaf weeds in grain sorghum. Foliar bleaching of sorghum leaves can occur but the symptoms are transient, and grain yields are not likely to be reduced.
Ενζυμική δια-εστεροποίηση λιπών και ελαίων μέσα σε μικρογαλακτώματα (1989)

Η δια-εστεροποίηση των λιπών και των ελαίων είναι μια από τις επεξεργασίες βελτίωσης που απασχολεί πολλές βιομηχανίες τροφίμων. Η κλασική μέθοδος της χημικής κατάλυσης που ακολουθείται, έχει πολλά μειονεκτήματα, όπως η έλλειψη εξειδίκευσης και το μεγάλο ενεργειακό κόστος. Αντίθετα η χρήση ενζύμων, όπως οι εξειδικευμένες λιπάσες εξασφαλίζει την παρασκευή συγκεκριμένων τριγλυκεριδίων με μεγάλη απόδοση. Το πρόβλημα της ετερογενούς καταλύσεως (υποστρώματα λιποδιαλυτά και ένζυμο υδατοδιαλυτό) λύνεται κάνοντας την αντίδραση μέσα σε μικρογαλακτώματα. Η χρήση αυτών των θερμοδυναμικά σταθερών μικροδιασπορών νερού μέσα σ' έναν οργανικό διαλύτη, αυξάνει τη μεσεπιφάνεια μεταξύ των τριγλυκεριδίων και του ενζύμου, αυξάνοντας την απόδοση της αντιδράσεως. Ένα άλλο χαρακτηριστικό των συστημάτων αυτών είναι η δυνατότητα που παρέχουν για τη διεξαγωγή φασματοσκοπικών μελετών.
High-resolution longitudinal and shear wave spectroscopy for analysis of complex colloids (2000)

In the present paper we describe the applications of the high-resolution ultrasonic longitudinal and shear wave resonator techniques for food and bio-colloids. Our longitudinal wave technique allows us to measure the velocity and attenuation of ultrasonic waves with a resolution of 0.0001% for ultrasonic velocity and 0.1% for the ultrasonic attenuation in small volumes (0.1 to 1 ml) in the frequency range 4–20 MHz. The shear wave technique provides information on viscoelastic parameters of liquids and gels in the frequency range 4–25 MHz. Both techniques allow continuous, temperature ramp and automatic titration measurements for analysis of various processes in complex colloids. Examples of the application of both techniques for studying heat-induced milk coagulation, phase transitions in milk fats, acid milk gelation, and the detection of food pathogens are described. Combination of both techniques shows a high sensitivity to various processes, e.g., pregelation and gelation, in food colloids and provides the unique ability to evaluate simultaneously the changes in volume and shear viscoelastic moduli. Overall our ultrasonic measurements demonstrate their high potential for nondestructive analysis of complex food and bio-colloids.

Amide-Based Rotaxanes with Terephthal, Furan, Thiophene and Sulfonamide Subunits (1996)

The synthesis and characterization of new amide-based rotaxanes 6b-d containing terephthal, furan and thiophene subunits is described. Furthermore, the first rotaxanes ever obtained with sulfonamide bonds 6e, f are reported. These mechanically bonded compounds can be prepared in only few simple steps in nonstatistical high yields (up to 41%), which demonstrates that it is possible to significantly modify the structure of these species and of their components without disturbing the non-ionic template-effect responsible for the formation of their mechanical bonds.
Serum Levels of Soluble Tumor Necrosis Factor Receptors and Effects of Interferon Therapy in Patients With Chronic Hepatitis C Virus Infection (1999)

The TNF alpha-TNFRs system, especially the TNFR p75-mediated pathway, is involved in the hepatic inflammation-fibrosis process in chronic hepatitis C. The serum levels of sTNFR p75, but not sTNFR p55, were correlated with the serum levels of macrophage colony stimulating factor in this process.

SILICON SURFACE BARRIER DETECTORS FOR X-RAY SPECTROSCOPY. (1968)

Previous psycholinguistic findings showed that linguistic framing - such as the use of passive voice - influences the level of agency attributed to other people. To investigate whether passive voice use relates to people's personal sense of agency, we conducted three studies in which we analyzed existing experimental and observational data. In Study 1 (N = 835) we show that sense of personal agency, operationalized between participants as recalling instances of having more or less power over others, affects the use of agentive language. In Study 2 (N = 2.7 M) we show that increased personal agency (operationalized as one's social media followership) is associated with more agentive language. In Study 3 and its two replications (N = 43,140) we demonstrate using Reddit data that the language of individuals who post on the r/depression subreddit is less agentive. Together, these findings advance our understanding of the nuanced relationship between personal and linguistic agency.
Pharmacokinetics of Mitomycin C (MMC) after Intraperitoneal Administration of MMC-Gelatin Gel and Its Anti-tumor Effects against Sarcoma-180 Bearing Mice (1997)

Gelatin viscous solution containing mitomycin C (MMC) was prepared and its antitumor effects were evaluated toward sarcoma-180 (S-180) ascite tumor bearing mice. Among various gelatin concentrations, 3% and 5% gelatin solutions potentiated the antitumor effects of MMC (7.5 mg/kg) against S-180 bearing mice. A "bell-shaped" profile was observed between % release of MMC from the gelatin matrix and increased life span (ILS) %. On the other hand, in the case of 10 mg/kg dose of MMC, 7.5% and 10% gelatin solutions potentiated its antitumor effects. At both doses of 7.5 and 10 mg/kg of MMC, decrease in body weight of mice after intraperitoneal administration of MMC were suppressed by increasing the concentration of gelatin. To confirm a possible mechanism for increase in ILS % after intraperitoneal (i.p.) administration of the gelatin viscous solution containing MMC, we examined the pharmacokinetics of MMC after i.p. administration into rats. By the use of 3 % gelatin solution, mean residence time (MRT) and Tmax values were significantly prolonged, and Cmax was decreased as compared with the administration of MMC solution. These results suggested that the enhancement of antitumor effect of MMC by the gelatin viscous solution could be caused by decrease in the clearance rate of MMC from the peritoneal cavity to systemic circulation due to decreasing its diffusivity in gelatin matrix.
The photochemistry of previtamin D and tachysterol (1977)

Abstract Pathways of formation are discussed for the thirteen toxisterols, the isolation and structure determination of which have been dealt with in the preceding article. It is suggested that toxisterols A (C‐8 spiro compounds) and C (bicyclo[3.1.0]hexenes) originate from previtamin D through relaxation of the excited “tZc” form of its hexatriene system. The symmetry‐allowed conrotatory closure to a 5–6–10 cyclopropane ring constitutes a plausible first step for both reactions. The description of the formation of the bicyclohexene moiety of toxisterol C1 as a two‐step process is consistent with its stereochemistry; the configuration corresponds to an overall [ π 4 a + π 2 a ] route and not to the [ π 4 s + π 2 a ] pathway expected for a concerted photochemical process. For the formation of toxisterols A a series of steps following the initial cyclopropane ring closure ‐ comprising a hydrogen shift from C‐4 to C‐9 and bond formation between C‐4 and C‐8 ‐ to provide the C‐8 spirostructure is proposed. Toxisterol D1 can be formed from previtamin D (or tachysterol) by a photoinduced antarafacial [1,5] hydrogen shift. The cyclobuteno compound toxisterol E1 originates from excited tachysterol through a disrotatorye ring closure of the 6‐7‐8‐9 butadiene moiety. A rationalization is offered for the novel photochemical 1,6‐addition of alcohol to the conjugated triene system of previtamin D/tachysterol yielding the toxisterols B, as well as for the photoreduction to form toxisterol R1. The article concludes with comments on the general picture of photoconversions as it emerges from previous and present investigations.
Power efficient technology decomposition and mapping under an extended power consumption model (1994)

We propose a new power consumption model that accounts for the power consumption at the internal nodes of a CMOS gate. Next, we address the problem of minimizing the average power consumption during the technology dependent phase of logic synthesis. Our approach consists of two steps. In the first step, we generate a NAND decomposition of an optimized Boolean network such that the sum of average switching rates for all nodes in the network is minimum. In the second step, we perform a power efficient technology mapping that finds a minimal power mapping for given timing constraints (subject to the unknown load problem).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Synchronization of multifractal parameters of regional and global low-frequency microseisms (2010)

The vertical seismic records with sampling rate 1 Hz obtained from global IRIS broad-band seismic network (2004-2005, 123 stations) and Japan F-net (1997-2010, 83 stations) were analyzed by estimating their multifractal singularity spectra parameters (the width of singularity spectra support and generalized Hurst’s exponent, i.e. argument providing maximum to singularity spectra) within adjacent short time windows of the length 30 minutes.
Bounding Temporally Correlated Measurement Noise with an Application to GNSS Integrity (2020)

In GNSS techniques like Precise Point Positioning (PPP), many of the errors affecting the position solution are modelled and estimated over time. In order to use PPP or related techniques for applications that require integrity, we need models of the errors that will lead to upper bounds of the estimated error covariance. In this work, we use the properties of the power spectral density to develop error models that bound autoregressive models with uncertain parameters. As an example, we show how this approach can be applied to the determination of a first order model that bounds the clock and ephemeris errors of GPS for multiple satellites.
Interactions of Bovine Neurophysin II with Oxytocin and [8-Lysine] Vasopressin (1974)

Interactions of bovine neurophysin II with oxytocin and [Slysinelvasopressin have been studied using proton Fourier transform nuclear magnetic resonance spectroscopy.The nuclear spin relaxation times, TX and Tz, of tyrosyl aromatic protons of oxytocin and of tyrosyl and phenylalanyl aromatic protons of [&lysine]vasopressin were measured in the presence of varying amounts of neurophysin II.In each case the relaxation time Tz was markedly decreased in the presence of neurophysin II while the relaxation time T1 was unaffected.The shortened transverse relaxation times for the protons of the bound hormones were independent of nuclear magnetic resonance frequency and were found to be dependent upon temperature in a manner that demonstrates that both hormones exchange rapidly between free solution and the hormone-neurophysin II complex.The existence of fast exchange conditions permits the calculation of a rotational correlation time for the oxytocin-neurophysin II complex of 5 x 10B8 s.These results indicate that the motional freedom of residues 2 and 3 of the hormone molecules is markedly restricted upon complex formation with neurophysin II, thereby suggesting that residues 2 and 3 of oxytocin and [8lysinejvasopressin are directly involved in the binding with neurophysin 11.The nonapeptide hormones oxytocin and [84ysine]vasopressin are known to bind to bovine neurophysins (l-3).The thermo-
Analogue interpolation based direct digital frequency synthesis (2003)

A low-power ROM-less direct digital frequency synthesis (DDFS) system that exceeds the spectral purity of existing low-power DDFS systems by approximately 10 dB is presented. The design applies an analogue voltage to the CMOS differential current switch in one cell of a non-linear DAC to interpolate between the output values which would be available from a conventional non-linear DAC.
Intramolecular Directional Förster Resonance Energy Transfer at the Single-Molecule Level in a Dendritic System (2003)

We report on the directional Förster resonance energy transfer (FRET) process taking place in single molecules of a first (T1P4) and a second (T2P8) generation of a perylenemonoimide (P)-terrylenediimide (T)-based dendrimer in which the chromophores are separated by rigid polyphenylene arms. At low excitation powers, single-molecule detection and spectroscopy of T1P4 and T2P8 dendrimers point to a highly efficient directional FRET from P donors to the central T acceptor, optical excitation at 488 nm resulting in exclusively acceptor emission in the beginning of the detected fluorescence intensity. Donor emission is seen only upon the bleaching of the acceptor. High-resolution time-resolved single-molecule fluorescence data measured with a microchannel plate photomultiplier reveal, for T2P8, a broad range of FRET rates as a result of a broad range of distances and orientations experienced by the donor-acceptor dendrimers when immobilized in a polymer matrix. Single-molecule data from T2P8 on 488 nm excitation are indicative for the presence, after terrylenediimide bleaching, of a P-P excited dimer characterized by a broad emission spectrum peaking around 600 nm and by fluctuating fluorescence decay times. At high excitation powers, single T1P4 and T2P8 molecules display simultaneous emission from both donor and acceptor chromophores. The effect, called "exciton blockade", occurs due to the presence of multiple excitations in a single molecule.
A new class of biodegradable hydrogels stereocomplexed by enantiomeric oligo(lactide) side chains of poly(HEMA‐ <i>g</i> ‐OLA)s (2000)

Two enantiomeric amphiphilic graft copolymers consisting of water soluble poly(2-hydroxyethyl methacrylate) (HEMA) and biodegradable oligo(L-lactide) (OLLA) or oligo(D-lactide) (ODLA) were synthesized by free radical copolymerization. HEMA-OL(D)LA macromonomers were synthesized by ring opening polymerization of L- or D-lactide. Both HEMA-OLA macromonomers and graft copolymers were characterized by NMR spectroscopy and gel permeation chromatography. Graft copolymers and their stereocomplexes were analyzed by wide angle X-ray diffraction and differential scanning calorimetry (DSC). Due to the formation of stereocomplex crosslinks between poly(HEMA) main chains, amphiphilic, biodegradable hydrogels prepared by blending of two enantiomeric poly(HEMA-g-OLLA) and poly(HEMA-g-ODLA) degraded more slowly in phosphate buffered saline than individual optically pure poly-(HEMA-g-OL(D)LA).
<sup>31</sup>P Nuclear Magnetic Resonance Studies of Anoxia in Aged Rat Brain (1984)

In addition to confirming previously reported findings related to changes in high-energy phosphates consequent to anoxia, 31P nuclear magnetic resonance studies of rat brain indicated that maintenance of energy-rich phosphates is less effective in the aged brain than in the mature cerebrum.
Improved coding of tonal components in MPEG-4 AAC with SBR (2008)

Proposed is a new technique of effective regeneration of high-frequency tonal components in an augmented MPEG-4 AAC HE decoder. The basic idea is to synthesize the tonal components using the technique called synthetic sinusoidal coding that is already adopted in the MPEG-4 codecs in another context. Here, the idea is to mix this technique with standard Spectral Band Replication (SBR), i.e. to add some control information to a standard MPEG-4 AAC HE bitstream that is used to synthesize the high-frequency tonal components in a decoder. In that way, provided is proper synthesis of rapidly changing sinusoids as well as proper harmonic structure in the high-frequency band. The experiments show that the tool improves significantly the compression performance when added to an MPEG-4 AAC HE codec. This improvement has been confirmed by listening tests. 1.

Performance bounds evaluation of FH SS radio networks with interference modeled as a mixture of Gaussian and alpha-stable noise (2002)

We consider the performance of frequency-hopping spread spectrum (FH SS) radio networks in a Poisson field of interfering terminals using the same modulation and power. The problem is relevant to mobile communication systems where the mobility of users requires random modeling of transmitter positions in the network. Assuming logarithmic attenuation of the signal strength over distance between the transmitter and receiver, we show that the interference in the network could be modeled as a mixture of Gaussian and circularly symmetric /spl alpha/-stable noise. Based on this model, we derive union bound approximations for the probability of error for FH systems with M-ary frequency shift keying (FSK). We generalize some of the results of Sousa (see IEEE Trans. I.T., vol.38, no.6, p.1743, 1992), where the focus was limited to Cauchy random variables (RVs), a special subclass of stable distributions, and where the effect of a background (Gaussian) noise was neglected. Numerical calculations and Monte Carlo simulations confirm the accuracy of our analysis. The results obtained allow the prediction of wireless system performance in environments varying from urban settings to office buildings.
