Modulation in vitro of immune parameters in homosexual males with the preclinical complex of symptoms related to acquired immune deficiency syndrome by azimexon. (1986)

In search of potential therapeutic agents for the acquired immunodeficiency syndrome (AIDS) among homosexual males, we studied in vitro the immunorestorative effect of azimexon in patients with this syndrome. Since a reduction in the ratio between helper inductor and suppressor/cytotoxic T-cell subsets (OKT-4/OKT-8) seems to be the hallmark of the syndrome, we measured azimexon-induced numerical changes in T-cell subsets and correlated them with changes in a simultaneously tested T-cell function as measured by the xenogeneic local graft-versus-host reaction (GVHR). Following incubation of peripheral blood mononuclear cells from 10 homosexual subjects with 10 micrograms/ml of azimexon at 37 degrees C for 1 h, the median number of T cells defined by the OKT-8 phenotype declined from 0.6 X 10(3) to 0.33 X 10(3)/mm3 (p less than 0.02), resulting in an increase in the OKT-4/OKT-8 ratio from 0.65 to 1.37 (p less than 0.01). There were no numerical changes in T cells defined by OKT-3 and OKT-4 phenotypes. Similar decreases in OKT-8-defined T cell occurred among eight heterosexual controls. The restoration of the OKT-4/OKT-8 ratio among the homosexual subjects was associated with a significant improvement in their T-cell function. Thus, the median volume of the local GVHR increased from 38.2 to 63.5 mm3 (p less than 0.02). Parallel changes in OKT-4/OKT-8 ratio and changes in local GVHR following incubation with azimexon were observed. These results suggest that azimexon may be an important immunorestorative agent. Clinical trials with this agent in patients with AIDS or its preclinical complex of symptoms seem warranted.

Graft Copolymerization of Chitosan with Butyl Acrylate and Application of the Copolymers to Cotton Fabric (2005)

Abstract Graft polymerization of butyl acrylate (BuA) onto chitosan using potassium persulfate (KPS) as initiator was studied under different conditions. The grafting percentage (G%) and the grafting efficiency (GE%) increase by increasing KPS concentration up to 40 mmol/L then decrease thereafter. Another trend was observed with BuA concentration where G% increases significantly as BuA concentration increases within the range studied, i.e., 10%–100%, based on weight of chitosan sample (ows), meanwhile GE% exhibits a maximum at BuA concentration of 50% ows. Temperature acts in favor of grafting up to 65°C where maxima for both G% and GE% could be achieved. The grafting reaction is characterized by an initial fast rate during the first 60 minutes then levels off thereafter. Poly (BuA)-chitosan graft copolymers were applied to cotton fabric in presence and absence of low formaldehyde cross-linking agent. Introduction of the copolymer and the cross-linking agent to cotton fabric enhances the performance of the latter to a great extent provided that the copolymer and the cross-linking agent are applied in two subsequent steps. Fabric performance was assessed through monitoring, nitrogen content, crease recovery angle, tensile strength and elongation at break.
Integrated Microfluidic Nucleic Acid Isolation, Isothermal Amplification, and Amplicon Quantification (2015)

Microfluidic components and systems for rapid (<60 min), low-cost, convenient, field-deployable sequence-specific nucleic acid-based amplification tests (NAATs) are described. A microfluidic point-of-care (POC) diagnostics test to quantify HIV viral load from blood samples serves as a representative and instructive example to discuss the technical issues and capabilities of "lab on a chip" NAAT devices. A portable, miniaturized POC NAAT with performance comparable to conventional PCR (polymerase-chain reaction)-based tests in clinical laboratories can be realized with a disposable, palm-sized, plastic microfluidic chip in which: (1) nucleic acids (NAs) are extracted from relatively large (~mL) volume sample lysates using an embedded porous silica glass fiber or cellulose binding phase ("membrane") to capture sample NAs in a flow-through, filtration mode; (2) NAs captured on the membrane are isothermally (~65 °C) amplified; (3) amplicon production is monitored by real-time fluorescence detection, such as with a smartphone CCD camera serving as a low-cost detector; and (4) paraffin-encapsulated, lyophilized reagents for temperature-activated release are pre-stored in the chip. Limits of Detection (LOD) better than 10³ virons/sample can be achieved. A modified chip with conduits hosting a diffusion-mode amplification process provides a simple visual indicator to readily quantify sample NA template. In addition, a companion microfluidic device for extracting plasma from whole blood without a centrifuge, generating cell-free plasma for chip-based molecular diagnostics, is described. Extensions to a myriad of related applications including, for example, food testing, cancer screening, and insect genotyping are briefly surveyed.
<i>1A Voice Storage System</i>: New Custom Calling Services (1982)

In creating new customer services, systems engineers traditionally conduct market needs analysis, engineering feasibility studies, and project economic analysis. Finally, they prepare development requirements. In addition, systems engineering designs the service from the customer's point of view. This article describes new custom calling services as the customer sees them and highlights some interesting features of the services.
Synthesis and Thermoelectric Property of Cu<sub>2−<i>x</i></sub>Se Nanowires (2010)

Single crystalline Cu2−xSe nanowires with lengths up to 50 μm are synthesized via a modified composite hydroxide mediated method. Experiments reveal that both quantity and species of hydroxides or amount of water used in the preparation would affect final morphology of Cu2−xSe crystals, from nanoplates to nanorods to nanowires. The UV−visible−near-infrared reflection spectrum demonstrates the absorption edges of the Cu2−xSe nanowires in the ultraviolet and near-infrared region, which could be interpreted in terms of direct transitions from a band gap of 2.38 eV and indirect transitions from a band gap of 1.12 eV. The band-to-band transition model has been proposed. In addition, Seebeck effect based on the Cu2−xSe nanowire film is investigated, demonstrating the Seebeck coefficient of 180 μV/K.
3-Aminobenzenesulfonic Acid:  A Disappearing Polymorph (2005)

We have identified and characterized the existence of two new polymorphic forms (orthorhombic needles and monoclinic plates) of 3-aminobenzenesulfonic acid, one of which was a previously unrecognized polymorphic form. The circumstances and events indicate that Form I may be considered a disappearing crystal form. The production of Form III was a serendipitous occurrence in an attempt to use the strategy of tailor-made additives to reobtain Form I; although unsuccessful, it has once more shown the need to explore as much of the chemical potential surface as possible even in a system as seemingly simple as this one.
Clinical pharmacology of 99mTc-labeled liposomes in patients with cancer. (1984)

The pharmacokinetics, organ distribution, and 24-hr urinary excretion of negatively charged 99mTc-labeled multilamellar liposomes, composed of dimyristoylphosphatidylcholine and dimyristoylphosphatidylglycerol in a 7:3 molar ratio, were studied in seven patients with cancer. The radiolabeled liposomes were administered i.v. in three doses: 150 mg/sq m of body surface area; 300 mg/sq m; and 450 mg/sq m of lipid. The dose of 99mTc was 4.8 to 7.6 mCi per patient. The plasma disappearance curve was biphasic (half-life alpha = 5.53 min, half-life beta = 289 min), suggesting a two-compartmental model of distribution. The calculated volume of distribution indicated considerable tissue retention of liposomes. This was confirmed by body imaging. Twenty-four hr after injection, liposomes were localized in organs rich in reticuloendothelial cells, i.e., liver [44.5 +/- 9.1% (S.E.)], spleen [25.5 +/- 7.7%], lung [14.5 +/- 4.9%], and bone marrow. Although the hepatic uptake accounted for more than 40% of the total uptake, the spleen retained liposomes at a higher density. Cumulative urinary excretion of radioactivity was 13.4 +/- 1.5% over 24 hr. Liposome administration was safe and devoid of any adverse side effects. The results provide a basis for the use of liposomes as potential target-specific and safe drug carriers in the treatment of pathological conditions that involve organs rich in reticuloendothelial cells.
Signal perception, transduction, and gene expression involved in anthocyanin biosynthesis (1996)

Abstract Anthocyanin pigments provide fruits and flowers with their bright red and blue colors and are induced in vegetative tissues by various signals. The biosynthetic pathway probably represents one of the best‐studied examples of higher plant secondary metabolism. It has attracted much attention of plant geneticists because of the dispensable nature of the compounds it produces. Not unexpectedly, several excellent reviews on anthocyanin biosynthesis have been published over the last 5 years (Dooner et al., 1991; Martin and Gerats, 1993a, 1993b; Koes et al., 1994; Holton and Cornish, 1995). These reviews emphasize the late steps of pigment biosynthesis rather than the early and intermediate events of signal perception and transduction. This review is broader and not only covers the identification of components of the anthocyanin signal perception/transduction networks but also provides a description of our current understanding of how they evoke the responses that they do. Progress has derived from a combination of biochemical, molecular and genetic studies. We discuss a range of relevant research to highlight the different experimental approaches being used and the diverse biological systems under investigation.

A QUARTER‐MILLION POUND REPAIR BILL (1979)

SYNOPSIS LOGICAL theories can be postulated for the escalation in incidents of marine main diesel engine lubricant malfunction and associated corrosion. If they are correct, the forecast is temporarily gloomy, until preventive measures become generally used and some long term reformulations are carried out. A number of early‐warning signs can now be recognized. On‐board microbiological tests have proved of great value; biocides are now known which can protect oils in use and many infected systems have been successfully sterilized. Other “straight” oil infections are discussed briefly but as yet the financial implications of other known infections are less pressing.

Two-way shape memory behavior of shape memory polyurethanes with a bias load (2010)

Thermo-responsive shape memory polyurethane (SMPU) is a smart material that can respond to external heat by changing its macroscopic shape from a temporary configuration to a memorized permanent one. The temporary shape can be processed using mechanical forces above a certain temperature (the transition temperature) and can be maintained until the material acquires a certain thermal energy. Thereafter, the material will recover its memorized permanent shape. However, it is unclear what will occur if the thermal energy is then dissipated, i.e., the material temperature decreases. There are two possibilities: the material will respond to the dissipated energy, resulting in another macroscopic shape change; or nothing will happen beyond the thermal contraction. The former is called two-way shape memory (TWSM) behavior and the latter is called one-way shape memory behavior. This paper reports novel findings showing that TWSM behavior can be imparted to SMPUs using a thermo-mechanical treatment, i.e., imposing a constant stress on them after their temporary shaping. A series of experiments were carried out to characterize the TWSM behavior of SMPUs and to explain its mechanism.
Murine marrow‐derived mesenchymal stem cell: isolation, <i>in vitro</i> expansion, and characterization (2003)

In spite of the attention given to the study of mesenchymal stem cells (MSCs) derived from the bone marrow (BM) of humans and other species, there is a lack of information about murine MSCs. We describe the establishment of conditions for the in vitro expansion of plastic-adherent cells from murine BM for over 50 passages, and provide their characterization regarding morphology, surface marker profile and growth kinetics. These cells were shown to differentiate along osteogenic and adipogenic pathways, and to support the growth and differentiation of haematopoietic stem cells, and were thus operationally defined as murine mesenchymal stem cells (mMSCs). mMSCs were positive for the surface markers CD44, CD49e, CD29 and Sca-1, and exhibited a homogeneous, distinctive morphology. Their frequency in the BM of adult BALB/c and C57Bl/6 mice, normal or knockout for the alpha-L-iduronidase (IDUA) gene, was preliminarily estimated to be 1 per 11,300-27,000 nucleated cells. The emergence of a defined methodology for the culture of mMSCs, as well as a comprehensive understanding of their biology, will make the development of cellular and genetic therapy protocols in murine models possible, and provide new perspectives in the field of adult stem cells research.
A pricing and accounting architecture for QoS guaranteed services on a multi-domain network (2003)

An efficient pricing and accounting scheme is required in order to guarantee fare competition among network providers aiming for continuous network progress. We discuss the revenue flow for several connectionless services these providers can offer. In particular, a new pricing and accounting mechanism is proposed for guaranteed type services. This is based on the network access agent, called NAgent, that mediates between users and network providers. The NAgent software architecture, based on the TINA business model, and its routing algorithm are also discussed.
On the efficiencies of piezoelectric energy harvesting circuits towards storage device voltages (2007)

Using piezoelectric elements to harvest energy from ambient vibrations has been of great interest over the past few years. Due to the relatively low power output of piezoelectric materials, energy storage devices are used to accumulate harvested energy for intermittent use. Piezoelectric energy harvesting circuits have two schemes: one-stage and two-stage energy harvesting. A one-stage energy harvesting scheme includes a conventional diode bridge rectifier and an energy storage device. In recent years, two-stage energy harvesting circuits have been explored. While the results shown in previous research and development are promising, there are still some issues that need to be studied. Energy storage devices such as rechargeable batteries and supercapacitors have different cell voltages. Moreover, the storage cells can be connected in series to increase the voltage range. The storage device voltage is an important factor that influences the energy harvesting efficiency. This paper will study the efficiencies of the energy harvesting circuits considering the storage device voltages. For one-stage energy harvesting, expressions are derived to calculate the efficiencies towards different storage device voltages and verified by experiments. For two-stage energy harvesting circuits, theoretical efficiency expressions are derived and verified by PSPICE simulations. These two energy harvesting schemes are also compared. The results show that a one-stage energy harvesting scheme can achieve higher efficiency than the two-stage scheme towards a range of energy storage voltages.
