Electrochemiluminescence from Calixarene-Coated Porous Si Liquid Junction Cells (1997)

In this paper, the electrochemiluminescence (ECL) of calixarene carboxylic acid coated porous Si (PS) is reported. Electrochemiluminescence is observed from the anodic oxidation of calixarene-coated porous Si in an electrolyte containing 1.0 M H2SO4. These calixarene carboxylic acid derivatives coated onto the porous Si surface affect both the duration and efficiency of the light emission. Electrochemiluminescence can be generated for longer periods of time for these coated porous Si junctions relative to untreated porous Si, ranging from up to 3 h for calix[4]arene-coated porous Si to about 50 min for the calix[n]arene (n = 5, 7, 8) derivatives. This improved duration of electrochemiluminescence comes at the cost of quantum efficiency; for calix[8]arene-coated PS it is 0.0015%, while for calix[4]arene-coated porous Si, <0.001%. The electrochemiluminescence peak maximum is red-shifted beyond 700 nm with continued bias. These observations are attributed to packing differences between different calixarene carboxylic acid derivatives as thin films and subsequent bias-induced Si nanoparticle oxidation in the porous matrix.
Prevention of hypoxemia during dialysis by the use of sequential isolated ultrafiltration-diffusion dialysis with bicarbonate dialyzate. (1981)

Previous studies have demonstrated that hypoxemia does not occur during isolated ultrafiltration, but does occur during diffusion dialysis with acetate, whether it is performed alone or following a period of isolated ultrafiltration. To determine if the substitution of bicarbonate for acetate in dialyzate could prevent hypoxemia, we studied the effect of sequential isolated ultrafiltration-diffusion dialysis with bicarbonate on arterial oxygen concentration. There was no significant change in pO2 during isolated ultrafiltration or the subsequent period of diffusion dialysis. In addition, excess body fluid could be removed and effective dialysis achieved without marked tachycardia or fluctuation in blood pressure. We conclude that sequential isolated ultrafiltration diffusion dialysis with bicarbonate is a safe and effective way of dialyzing patients without producing hypoxemia or cardiovascular instability.
An efficient generalized sphere decoder for rank-deficient MIMO systems (2005)

We derive a generalized sphere decoder (GSD) for rank-deficient multiple input multiple output (MIMO) systems using N transmit antennas and M receive antennas. This problem arises when N>M or when the channel gains are strongly correlated. The upper triangular factorization of the Grammian yields an under-determined system and the standard sphere decoding (SD) fails. For constant modulus constellations, we modify the maximum likelihood (ML) cost metric so that the equivalent Grammian is rank N. The resulting GSD algorithm has significantly lower complexity than previous algorithms. A method to handle non-constant modulus constellations is also developed.
A Noncentrosymmetric 3D Coordination Polymer of Metallocalix[4]arene (2008)

Sequential reaction of a lower-rim functionalized calix[4]arene, 25,27-bis(hydroxycarbonylmethoxy)-26,28-dimethoxy-p-tert-butylcalix[4]arene (H(2)L(C4)), with K(2)CO(3) and CoCl(2).6H(2)O in ethanol afforded a 3D coordination polymer [K(3)Co(2)(L(C4))(3)(EtOH)(6)]Cl (1). X-ray crystal analysis revealed that 1 features a noninterpenetrated (10,3)-a net structure wherein octahedral Co(2+) ions serve as the three-connecting nodes and [K(L(C4))](-) units function as the bridges between the Co(2+) ions. The calixarene ligands in 1 adopt a 1,3-alternate conformation, and there are considerable cation-pi interactions between the K(+) ion and the phenyl rings within each [K(L(C4))](-) unit.
Spatio-Temporal Pattern for Expression of Galectin-3 in the Murine Utero-Placental Complex: Evidence for Differential Regulation1 (1998)

In mice, immunoreactive galectin-3 protein has previously been localized in uterine epithelial cells adjacent to implanting blastocysts as well as in the decidualized endometrium of implantation sites, uterine natural killer cells, and several types of placental trophoblast cells. Because galectin-3 is a soluble extracellular molecule, protein localization by immunohistochemical methods does not demonstrate its cellular origin. Therefore, the present study was undertaken to determine precisely which cell types in the utero-placental complex express galectin-3 mRNA. In situ hybridization results demonstrated that galectin-3 mRNA was expressed throughout the utero-placental complex in all cell types previously shown to contain immunoreactive protein, including uterine epithelium, decidualized endometrium, uterine natural killer cells, and placental trophoblasts. These results indicate that galectin-3 protein is not synthesized in a restricted cell type and translocated through the extracellular spaces to other tissue compartments. Furthermore, Northern blot analysis of total RNA prepared from separated fetal and maternal components of utero-placental complexes demonstrated different patterns of expression for galectin-3 mRNA in the uterus and placenta. Relative levels of galectin-3 mRNA peak at midgestation in the implantation site and during the second half of gestation remain elevated in the placenta but decline in the uterus. Separate mechanisms for regulating expression of galectin-3 on opposite sides of the feto-maternal interface are indicated.
THE BIOASSAY OF PROGESTERONE<sup>1</sup> (1957)

IT WAS first observed by Lutwak-Mann (1) that gonadotrophins, progesterone and certain other luteoids injected into estrous adult or estrogen-primed immature rabbits produced marked increases in the content of uterine carbonic anhydrase, the extent of which depended upon the dosage, and this was accompanied by histological evidence of progestational proliferation (2). It was therefore suggested that the measurement of endometrial carbonic anhydrase might be used as a basis for progestin assay, and subsequently Lutwak-Mann and Adams (3) have compared endometrial carbonic anhydrase titers and the degree of progestational proliferation as measured by the Robson (4) scale, using progesterone and other steroids. The specificity of the enzyme reaction appears to be substantiated by their data, but quantitation and definition of sensitivity were not attempted. In this paper we present: (a) a statistical analysis of the dosage response data for progesterone in the conventional Clauberg rabbit, (b) a comparison of the enzyme response with measurements of progestational
[The structural-functional properties of the erythrocyte membranes in patients with ischemic stroke and circulatory encephalopathy]. (1994)

68 patients with cerebrovascular disorders (37 cases of ischemic stroke and 31 cases of dyscirculatory encephalopathy) were examined for microhemorheology (erythrocytic form and deformability); fractional composition of neutral lipids; blood phospholipids; those in red cells and their membrane environment (ME); erythrocytic sorption capacity in plasma and ME by fibrinogen. Neutral lipids were found to undergo metabolic disorders manifested as lowered amount of phospholipids, elevated levels of free fatty acids, triglycerides and cholesterol ethers. The fractional composition shifted to a growing toxic fraction of lysophosphatides and reducing fraction of phosphatydilcholine. The changes were of the same type in all the tested media and seemed interrelated. Along with alterations in the membrane lipid composition there appeared functional changes in erythrocytes: deformability decreased, echinocytes emerged, membrane sorption capacity enhanced, ME fibrinogen rose.
Insect resistance to Bacillus thuringiensis: uniform or diverse? (1998)

Resistance to the insecticidal proteins produced by the soil bacterium Bacillus thuringiensis (Bt) has been documented in more than a dozen species of insect. Nearly all of these cases have been produced primarily by selection in the laboratory, but one pest, the diamondback moth ( Plutella xylostella ), has evolved resistance in open–field populations. Insect resistance to Bt has immediate and widespread significance because of increasing reliance on Bt toxins in genetically engineered crops and conventional sprays. Furthermore, intense interest in Bt provides an opportunity to examine the extent to which evolutionary pathways to resistance vary among and within species of insect. One mode of resistance to Bt is characterized by more than 500–fold resistance to at least one Cry1A toxin, recessive inheritance, little or no cross–resistance to Cry1C, and reduced binding of at least one Cry1A toxin. Analysis of resistance to Bt in the diamondback moth and two other species of moth suggests that although this particular mode of resistance may be the most common, it is not the only means by which insects can attain resistance to Bt.
Noise characteristics of tunneling magnetoresistive sensors (2003)

Summary form only given. The noise of tunneling magnetoresistive sensors (TMR) has been measured in the frequency domain as a function of applied magnetic field (up to 4 T), temperature (4 K to 400 K), and bias current (up to 5 mA). The bias current was applied to a sensor through a bias tee. The AC noise signal from the sensor was decoupled from DC signal by the bias tee with a low cut off frequency of 5 kHz, and was measured by a spectrum analyzer. Noise voltage-spectral density (S/sub v/) was measured with a resolution bandwidth of 30 kHz for two types of sensors with different permanent magnet biases. The position of the noise peaks was in the range from 100 MHz to a few GHz, which is close to a typical data rate of hard disk drives. More detailed analyses revealed that these noise peaks may result from a uniform precession of magnetization in the free layer, possibly due to poor bias. Shot noise of the TMR sensors was also measured at room temperature with bias current of 3 mA under a very high magnetic field of 4 T. Sv observed under 4 T was very close to that of a 49 ohm non magnetic resistor at frequencies above 100 kHz, suggesting that shot noise may not be a dominant noise source in good TMR sensors.
Dynamics of repulsive dual-frequency atomic force microscopy (2009)

In bimodal atomic force microscopy, two flexural modes are driven at their resonances. The oscillation of the second eigenmode, which is usually an incommensurate multiple of the fundamental frequency, perturbs the dynamic system. Numerical simulations show that the tip motion is almost periodic at typical set points and that harmonics and intermodulation frequencies prevail in the spectrum. The simulations also predict a very small increase in the noise of the first mode amplitude and phase due to the second mode oscillation. At small average tip sample separations, however, phases with repulsive and purely attractive forces can occur intermittently.

Automatic Email Response System in E-learning (2016)

E-Learning has become an essential element in everyday life. This method of teaching is being used to teach the students who are at remote location. This method has many advantages over the traditional method of teaching but there are several limitations in this method. One of those limitations is what if a student has a query? Probably, the answer seeking student will shoot an e-mail to the teacher along with his query and the teacher will reply with appropriate answer. The problem arises when many students ask the same query and the teacher has to reply each of them. There should be some kind of automation that can find that this query has been already answered and the system should reply with the appropriate answer. In this paper, we proposed an approach for an automatic email response system based on semantic similarity between queries and comparing between semantic similarity and semantic relatedness and find out which one is best for finding correct sense in query and finding score on the basis of sense match. System will be able to respond the email queries provided response will be available in the database.
Selection of novel forms of a functional domain within the<i>Tetrahymena ribozyme</i> (1994)

P5abc is an RNA structure within the self-splicing Tetrahymena group I intron that provides an activation function to the remainder of the ribozyme, either when present in cis or when added in trans. This 69-nucleotide activator domain was replaced with randomized sequence of 20 or 40 nt in length, and individuals among these pools with sequences that could functionally replace P5abc were selected. The basis of selection was a reaction in which two separate halves of the ribozyme became joined; selection was completed by reverse transcription and the polymerase chain reaction, using primers with sequence from either side of the ligation junction. Selectant sequences fell into three families that appear unrelated to P5abc; for example they lack the A-rich bulge thought to be a important feature of P5abc. Thus, rather than defining some consensus sequence for activator domains, this result reveals a certain tolerance in the ribozyme in its ability to derive activation function from diverse sequence types. In the context of splicing precursor RNA, the new sequences supported self-splicing, but failed to activate a related reaction, hydrolysis of the 3' splice site, implying that this region of the intron can differentially control two related reactions.

Discovery of Inhibitors of MCF‐7 Tumor Cell Adhesion to Endothelial Cells and Investigation on their Mode of Action (2004)

Metastasis, the main reason for high mortality of cancer, is a multistep process. One important step in this process is the adhesion of tumor cells to vascular endothelium at sites distant from primary tumors during hematogenous dissemination. In order to investigate and quantify the adhesion of tumor cells to endothelial cells we developed an in vitro model using MCF-7 breast cancer cells and monolayers of human umbilical vein endothelial cells (HUVEC). The tumor cells were specifically labeled with a fluorescent dye for quantification; for increasing the amount of adherent cells, HUVEC monolayers were stimulated with phorbol ester before the addition of the tumor cells. Due to previous reports that products of several P450 enzymes contribute to the progression of certain kinds of cancer, inhibitors of CYP5 (thromboxane A(2) synthase), CYP17 (17alpha-hydroxylase-C17, 20-lyase), and CYP19 (aromatase) were tested in this in vitro model for their potency to reduce cancer cell adhesion. Within each series of P450 inhibitors, compounds with high inhibitory activity on tumor cell adhesion were identified. At an initial concentration of 100 microM, BW26, a potent inhibitor of CYP5, reduced tumor cell adhesion of MCF-7 to HUVECs to 15%, BW40 (CYP17) to 29%, and SU5a (CYP19) to 11% of the corresponding controls (no inhibitor). Reduction of tumor cell adhesion was shown to occur in a concentration-dependent manner. In addition to these inhibitors of CYP5, CYP17, and CYP19, liarozole, known to be a potent inhibitor of CYP26 (retinoic acid-4-hydroxylase) and ATRA (all-trans-retinoic acid) metabolism, was able to reduce tumor cell adhesion to 51% of the initial rate. Experiments elucidating the mode of action of these compounds revealed that inhibition of the mentioned CYP enzymes is not responsible for their ability to reduce tumor cell adhesion.
Depletion of thiol‐containing proteins in response to quinones in <i>Bacillus subtilis</i> (2008)

Quinones are highly toxic naturally occurring thiol-reactive compounds. We have previously described novel pathways for quinone detoxification in the Gram-positive bacterium Bacillus subtilis. In this study, we have investigated the extent of irreversible and reversible thiol modifications caused in vivo by electrophilic quinones. Exposure to toxic benzoquinone (BQ) concentrations leads to depletion of numerous Cys-rich cytoplasmic proteins in the proteome of B. subtilis. Mass spectrometry and immunoblot analyses demonstrated that these BQ-depleted proteins represent irreversibly damaged BQ aggregates that escape the two-dimensional gel separation. This enabled us to quantify the depletion of thiol-containing proteins which are the in vivo targets for thiol-(S)-alkylation by toxic quinone compounds. Metabolomic approaches confirmed that protein depletion is accompanied by depletion of the low-molecular-weight (LMW) thiol cysteine. Finally, no increased formation of disulphide bonds was detected in the thiol-redox proteome in response to sublethal quinone concentrations. The glyceraldehyde-3-phosphate dehydrogenase (GapA) was identified as the only new target for reversible thiol modifications after exposure to toxic quinones. Together our data show that the thiol-(S)-alkylation reaction with protein and non-protein thiols is the in vivo mechanism for thiol depletion and quinone toxicity in B. subtilis and most likely also in other bacteria.

Fingerprint shell structure on acid-etched Cretaceous oysters (Mollusca, Bivalvia) from Mississippi (1984)

Specimens of Gryphaea mutabilis and Exogyra costata etched in dilute hydrochloric acid develop complex patterns on the interior of their valves. These patterns, named fingerprint shell by Stenzel, were previously known from only one species of oyster, the extant Alectryonella plicatula (Gmelin). This shell structure seems related to flow patterns of water pumped through the oyster9s internal cavity.--Modified journal abstract.

The structures of these compounds have been elucidated by the (1)H- and (13)C-NMR spectra and two-dimensional NMR methods.
900 MHz private radio communication system - A proposed solution for consumer communication needs (1983)

After a study of communications requirements for consumers, the General Electric Company has petitioned the FCC to establish a new personal radio service that is tailored to meet the consumer's desire for low cost mobile radiotelephone service. It would provide local area coverage and complements existing or planned communication services. Based on U.S. Dept. of Transportation studies of consumer driving habits, the proposed Private Radio Communication System (PRCS) is a 150 channel, trunked mobile radiotelephone system that will allow voice communications on an addressed basis over either direct or repeatered communication channels. Voice channel selection is transparent to the consumer as a result of the distributed control function which uses five dedicated control channels and an ALOHA access strategy to exchange command data packets during the channel selection process. Because of the distributed control function, a mobile unit and a base station can operate either as a stand-alone "system" or as part of a multi-channel repeater system. The design of the command message allows a telephone number to be included in the message so that telephone calls may be made on the public switched telephone network through the consumer's base station. Provisions are made for call length limitation as system loading exceeds 70%, disconnect signalling and time-out due to loss of carrier. This paper describes the basic system design objectives, system concept, and command message format.
