Prevention of wound dehiscence in severely obese patients with jejuno-ileal by-pass: the role of hyaluronic acid. (1988)

There is a high incidence of wound dehiscence, ranging from 6.9% to 22%, after surgery for severe obesity. Different surgical techniques to minimize this drawback of the operation have been proposed, but none have seemed to be really effective. A different approach to this problem has been tried using topical treatment with hyaluronic acid through the drains of the laparotomy suture. Twenty patients subjected to jejuno-ileal by-pass for severe obesity were randomized into two treatment groups: hyaluronic acid (80 mg/daily) or placebo (saline), for 5 days, starting at the operation. Granulation tissue was withdrawn from the wound through polyvinyl catheters 1, 3 and 5 days after the operation. It was processed for light, scanning and transmission electron microscopy. Ten days after the operation, the wounds were examined for dehiscence. Hyaluronic acid treatment reduced the incidence and degree of dehiscence macroscopically, increased the maturation of granulation tissue during the first post-operation days and stimulated fibroblasts to synthesize procollagen shortly after the operation.

Linearity Improved Doherty Power Amplifier Using Composite Right/Left-Handed Transmission Lines (2008)

A Doherty power amplifier using composite right/left-handed transmission lines (CRLH-TL) is proposed for linearity improvement. The lambda/4 transmission line incorporating CRLH-TL is designed to suppress the second harmonic of the output of the main amplifier. The output power of the proposed power amplifier at the fundamental frequency (2.30 GHz) shows 31.0 dBm with 13 dBm input power excited. The Doherty power amplifier using CRLH-TL improves the linearity considerably compared to that without employing CRLH-TL.
Observation of Kerr nonlinearity in microcavities at room temperature (2005)

We have devised and experimentally verified a method for observation of the optical Kerr effect in microcavities at room temperature. The technique discriminates against the much larger and typically dominant thermal component of nonlinearity by using its relatively slow frequency response. Measurement of the Kerr coefficient or equivalently of the third-order nonlinear susceptibility of the cavity material is demonstrated for a silica microcavity. With this approach, useful information about the characteristic thermal response time in microresonators can also be acquired.
IR spectroscopic study of the effects of high pressure on zeolites Y, A and sodalite (1998)

In this work, we present the effect of high external pressure on the structures of several representative zeolites: zeolite Y (Na-Y), lithium exchanged zeolite A (Li-A) and sodalite, as studied by IR spectroscopy. Pressure-induced amorphization was observed at 19 and 18 kbar in Na-Y and Li-A, respectively. However, the amorphous phases formed under such pressures seem to be reversible. The structural memory of the glasses might be due to the presence of hydrated charge balancing cations. Sodalite, on the other hand, exhibited no phase change in the pressure range of 0–48 kbar.
Dual-polarized slot-coupled patch antennas on Duroid with teflon lenses for 76.5-GHz automotive radar systems (1999)

A dual-polarized 76.5-GHz microstrip patch and teflon lens antenna system was designed, constructed, and tested. A receiver (RX) array of three dual-polarized microstrip patches was coupled through a 10-cm-diameter lens to produce radiation patterns with 3/spl deg/ beamwidths and beam crossovers of -3 dB. The transmitter (TX) consisted of a single dual-polarized microstrip patch coupled through a 2.5-cm-diameter lens to produce a 10/spl deg/ beamwidth. Slot-coupled patches were used to isolate the microstrip feed circuit from the radiating elements. The antennas and feeds were fabricated on commercially available 5880 Duriod substrates. Cross-polarization levels were less than -20 dB and were typically less than -30 dB over the entire beam at the design frequency. First sidelobe levels were no greater than -15 dB and were typically closer to -20 dB. Stepped and unstepped versions of the 10-cm-diameter receive lens were designed and fabricated. Antenna system sidelobes levels were lower with the stepped lens while the cross-polarization levels were comparable.
Closely-Packed UWB MIMO/Diversity Antenna With Different Patterns and Polarizations for USB Dongle Applications (2012)

A closely-packed ultrawideband (UWB) multiple- input multiple-output (MIMO)/diversity antenna (of two elements) with a size of 25 mm by 40 mm is proposed for USB dongle applications. Wideband isolation can be achieved through the different patterns and polarizations of the two antenna elements. Moreover, the slot that is formed between the monopole and the ground plane of the half slot antenna is conveniently used to further enhance the isolation at the lower frequencies and to provide an additional resonance at one antenna element in order to increase its bandwidth. The underlying mechanisms of the antenna's wide impedance bandwidth and low mutual coupling are analyzed in detail. Based on the measurement results, the proposed antenna can cover the lower UWB band of 3.1-5.15 GHz, and within the required band, the isolation exceeds 26 dB. The gains and total efficiencies of the two antenna elements are also measured. Furthermore, a chassis mode can be excited when a physical connection is required between the ground planes of the two antenna elements. Without affecting the performance of the half slot element, the monopole can now cover the band of 1.78-3 GHz, apart from the UWB band. The proposed antenna structure is found to provide good MIMO/diversity performance, with very low envelope correlation of less than 0.1 across the UWB band.
Interpretation of Temperature Observations From a Cyclic-Steam/ In-Situ-Combustion Project (1990)

Summary Data collected at 10 temperature observation wells were analyzed to evaluate the implementation of a combined process of cyclic steam stimulation followed by pressure-up/blowdown combustion for the in-situ recovery of bitumen. The temperature profiles at four observation wells, along the northeast/southwest fracture plane (on-trend direction), confirmed the height and orientation of the vertical fractures during cyclic steam stimulation. Six off-trend wells indicated that the heat transfer away from the fracture plane was predominantly conductive, with varying amounts of convective flow. During the in-situ combustion phase, frontal temperatures &gt; 2, 200°F [1200°C] were detected. Data also indicated that the vertical location of the combustion front can be controlled by either gravity or mobility effects. The off-trend heating was improved as a result of higher convective heat fluxes.
1,25-dihydroxyvitamin D3 synthetic analogs inhibit spontaneous metastases in a 1,2-dimethylhydrazine-induced colon carcinogenesis model. (2000)

In order to substantiate the role of vitamin D applicability for the prevention of colon cancer and its spontaneous metastases, the effect of 1,25-dihydroxyvitamin D3 and its synthetic analogs, 1, 25-dihydroxy-16,23Z-diene-26,27-hexafluoro-D3 (Ro 25-5317) and 1, 25-dihydroxy-16,23E-diene-26,27-hexafluoro-19-nor-D3 (Ro 25-9022), have been evaluated in a 1,2-dimethylhydrazine (DMH)-induced colon carcinogenesis model in Sprague-Dawley rats. In animals maintained on 2.75 nmol/kg 1,25-dihydroxyvitamin D3 diet no statistical difference was seen in tumor incidence when compared with control while in animals on 3.0 nmol/kg 1,25-dihydroxyvitamin D3 diet, the incidence of tumors was significantly lower. In animals maintained on 3.0 nmol/kg Ro 25-5317 diet also no statistical difference was seen in tumor incidence compared with control while in animals on 3. 5 nmol/kg Ro 25-5317 diet the incidence of tumors was significantly lower. The incidence of tumors in the group of animals maintained on 3.0 nmol/kg and 3.5 nmol/kg Ro 25-9022 was significantly lower, at 32.1% and 27.6% respectively, compared to control. In the two groups of animals maintained on the 1,25-dihydroxyvitamin D3 diet no significant difference in the incidence of metastasis was seen. In the group of animals maintained on 3.0 nmol/kg Ro 25-5317 diet only regional metastases were seen. However, no metastases developed in the rats on 3.5 nmol/kg Ro 25-5317 diet. After administration of 3.0 nmol/kg Ro 25-9022 diet, metastases developed in a significantly less number of animals while no metastases occurred in the rats maintained on the 3.5 nmol/kg Ro 25-9022 diet. The above studies will provide a scientific basis for the progression into further clinical trials in the treatment, and/or chemoprevention of human colorectal cancer.
A general approach to spirolactonized Si-rhodamines (2014)

A general approach has been developed for the synthesis of spirolactonized Si-rhodamines (SiRBs). The alternative synthetic route provides a facile opportunity to access various s bearing ring-expanded scaffolds and substituents for conjugation. By click reaction, a near-infrared (NIR) mitochondrial tracker was prepared, displaying specific mitochondrial staining in cells.
Postcataract surgical inflammation (2011)

Surface-Modified Amikacin-Liposomes: Organ Distribution and Interaction with Plasma Proteins (1998)

Amikacin-loaded liposomes were produced and surface-modified by adsorption of PEG 4000, Tween 80, poloxamer 407 and gelatin. The organ distribution was studied in mice by analysing the amikacin content in liver, spleen, lung, kidneys and serum. Highest serum levels were obtained with the PEG- and Tween 80 modified liposomes (at 2 hours p.inj.). Modification of the liposomes with gelatin as opsonization promoting agent distinctly increased the amikacin concentration in the liver from 36 to 66 mg/kg. Highest spleen concentrations were observed with non-modified and poloxamer 407 liposomes (242 mg/kg and 248 mg/kg, respectively). The data suggest that modification by a simple adsorption process is sufficient to effectively alter the organ distribution. The liposomes differing in organ distribution exhibited also different plasma protein adsorption patterns, up to 115 spots were detected by 2-D PAGE. Hydrophilic albumin was present in a conc. of appr. 80% on liposomes modified with ethoxylated compounds. On the gelatin liposomes, 14% of alpha-2-Macroglobulin were adsorbed which is a protein typically found on particles rapidly cleared by the RES. IgM, Apo A-I, Apo C-II and alpha-1-Antitrypsin were other detected proteins.
Isolation of a novel SUMO protein from tomato that suppresses EIX‐induced cell death (1999)

Challenging tomato or tobacco varieties with ethylene-inducing xylanase (EIX) from the fungus Trichoderma viride causes rapid induction of plant defence responses leading to programmed cell death. Using the yeast two-hybrid system, we isolated a novel protein, tomato small ubiquitin-related modifier protein (T-SUMO), which specifically interacts with EIX. T-SUMO, a cytoplasmic protein, is a member of the ubiquitin-like protein family. It shows homology to human protein sentrin/SUMO1, which suppresses tumour necrosis factor-induced cell death. Transgenic plants that express T-SUMO in the sense orientation suppress EIX induction of ethylene biosynthesis and cell death, while in the antisense orientation they enhance EIX-induced ethylene biosynthesis. These results indicate that T-SUMO is involved in mediating the signal generated by EIX that leads to induction of plant defence responses.
[The role of phospholipase D in cellular signaling]. (2005)

Phospholipase D (PLD) hydrolyzes structural phospholipids of biological membrane to produce phosphatidic acid (PA) and a free-head group. Both of these compounds can participate in signal transduction. Since the activation of PLD involved in many cellular signaling cascades was identified in recent years, knowledge of and interest in PLD have grown greatly, and significant progress has been made toward understanding PLD. This paper reviewed the research progress on gene structure, regulation and cellular function of PLD. PLDs are encoded by a multiple heterogenous gene family. The overall domain structures of plant PLDs are similar, but important differences occur in some of the motifs. The small structural variations underlie distinct regulatory and catalytic properties and cellular function in signaling. PA and other messengers produced by other phospholipase pathways can be interconverted with the action of lipid kinase and phosphatase. PLD is thought to function as an integral part of a network involving other lipid-signaling enzymes and messengers. Some research evidence demonstrated the specificity of PLDs in signal transduction with plant species, cell types, stimuli and cellular processes. Some important questions about PLD study were also raised.
A Comparison Study of the Thermal Performance of R12 and R134a (1992)

This paper discusses the findings of 'an experimental study designed to show the effect of changing refrigerants on the performance of a refrigeration system.The findings are based on a total of 88 independent tests using two refrigerants, namely R-12 and Rl34a.The test equipment consists of a fully instrumented, 3ton refrigeration system which provides values for the system COP, cooling capacity, mass flow rate, and thermodynami c states of the refrigerant at the inlet and exit of each compon,ent in the system.The parameters varied, in the study are the evaporator and condenser sink temperatures and the amount .. of refrigerant used in the system.The evaporator exit superheat was maintained constant at 13.5 F (7.5"C) for all tests.The experimental results show that for almost all test conditions the R134a operates with greater COP and cooling capacity.Th'is is especially true of the system when charged with Rl34a where the condenser subcooling is 10 to 15 F (5.6 to 7.5"C).The effects of operating conditions on system performance are presented in detail.Several questions are considered through examination of the thermodynami c states at key points in the system.For example, it is shown how the system can operate at a higher pressure ratio with R-134a and yet have a greater COP.than for the system 'charged with R12.
Futures Prices in Supply Analysis (1976)

Empirical work on agricultural supply functions typically makes use of product prices from past time periods. This approach has important advantage that it avoids problems created by simultaneous determination of supply and demand, since past prices are predetermined. But approach has important drawback that theory does not reveal exactly which past prices to use. The simplest procedure, use of last year's price, assumes farmers to be unduly naive in formation of expectations. The more sophisticated lagged-price procedures following work of Nerlove create econometric problems (Brandow, Nerlove 1958c, Griliches). Some are also liable to charge of theoretical ad-hockery (Griliches, p. 42ff). As an alternative approach to estimating supply elasticity, this paper is an attempt to exploit theoretically well-grounded hypothesis that price of a futures contract for next year's crop reflects estimate of next year's cash price.1 Since appropriate price for supply analysis is price expected by producers at time when production decisions are being made, a futures price at this time is a good candidate for a directly observable measure of product price in supply analysis. In context of crop supply, there are several problems to be faced in use of futures prices. First, the market's estimate as given by a futures price reflects expectations of nonfarm speculators as well as crop producers, and it reflects directly expectations only of those crop producers who themselves make futures transactions. Second, there is issue of which futures contract is most appropriate. Third, at what date should futures price be observed? With respect to first issue, use of a futures price can be justified by hypothesis of rational expectations as developed by John Muth. Under rational expectations, there is no reason for farmers to have different price expectations from futures speculators, nor for farmers who make no futures transactions to have expectations different from those who do. If price expectations of those out of futures market differ from futures price, there is great incentive for them to enter. Thus, those out of market likely have price expectations similar to market price of futures.2 The second issue should cause no serious problem so long as futures contract pertains to new crop. Of course, even old-crop cash prices are influenced by expectations concerning new crop. But cash-futures basis changes from year to year and secularly as cost of storage (which includes interest) changes. The present analysis uses first futures price after crop is in. The third problem is most difficult because it is not clear exactly when production decision is made. There may not be any preharvest date at which a farmer can be said to have made irrevoca-
Network-Aware Overlays with Network Coordinates (2006)

Network coordinates, which embed network distance measurements in a coordinate system, were introduced as a method for determining the proximity of nodes for routing table updates in overlay networks. Their power has far broader reach: due to their low overhead and automatic adaptation to changes in the network, network coordinates provide a new paradigm for managing dynamic overlay networks. We compare network coordinates to other proposals for network-aware overlays and show how they permit the lucid expression of a range of distributed systems problems in well-understood geometric terms.

The specific on-resistance (Ron,sp) of the SJ-VMOSFET is the lowest ever among all the reported SiC-MOSFETs with the blocking voltage (Bv) over 600 V. Superior electrical properties were realized with the structural combination of the V-groove MOS channel and the charge balance at super junction area. The Ron,sp analysis of SJ-VMOSFET was carried out after mounted on a TO-268 5pin package having a Kelvin source terminal.
