Enhanced glomerular thromboxane A2 mediates some pathophysiologic effect of platelet-activating factor in rabbit nephrotoxic nephritis: evidence from biochemical measurements and inhibitor trials. (1989)

Previous studies have shown that platelet-activating factor (PAF) receptor blocking has a protective effect on rabbit nephrotoxic nephritis (NTN). We examined whether arachidonic acid (AA) metabolism is altered in NTN and whether a PAF receptor antagonist has any influence on such changes. Rabbits injected with anti-glomerular basement membrane antiserum in the heterologous phase had a markedly increased glomerular thromboxane B2 (TxB2) production level, whereas no changes have been detected in glomerular 6-keto-prostaglandin F1 alpha (6-keto-PGF1 alpha) and prostaglandin E2 (PGE2). During the autologous phase of the disease, the glomerular TxB2 level was even higher than in the heterologous phase. The level of 6-keto-PGF1 alpha was significantly lower than normal, and the level of PGE2 was unchanged in respect to the basal values. The use of L-652,731 (a specific PAF receptor antagonist) reversed the abnormal generation of AA metabolites at glomerular level both in the heterologous and autologous phase of the disease. The effect of L-652,731 on AA metabolism is likely to be an indirect result of the PAF receptor blocking, because L-652,731 given to normal rabbits had no direct effect on glomerular AA metabolism. To assess whether the beneficial effect of L-652,731 in NTN is at least in part mediated by its capability of suppressing the excessive intrarenal synthesis of thromboxane A2 (TxA2), we compared the effect of L-652,731 with that of a selective TxA2-synthase inhibitor (FCE-22178). FCE-22178 ameliorated the morphologic expression of rabbit NTN and reduced function deterioration. The protective effect of L-652,731 on proteinuria in the autologous phase and on glomerular filtration rate in both phases was superior to that of FCE-22178. We conclude that an excessive intraglomerular synthesis of TxA2 occurs in rabbit NTN that can play a role in renal function deterioration. Both a specific PAF receptor antagonist and a TxA2-synthase inhibitor reduced the exaggerated TxA2 synthesis and favorably influenced the evolution of the disease.

Sleep Disruption in Epilepsy: Ictal and Interictal Epileptic Activity Matter (2020)

Sleep fragmentation in focal drug-resistant epilepsy is associated with ictal and interictal epileptic activity. The increase in interictal epileptic activity before arousals suggests its participation in sleep disruption. An additional increase in the spike rate during arousals may result from a sleep-wake boundary instability, suggesting a bidirectional relationship. ANN NEUROL 2020;88:907-920.

A new method of attaching a solid‐state pressure sensor for measurement of chronic intracranial pressure in freely moving rats using biotelemetry (2012)

Precise and long-term measurements of intracranial pressure (ICP) in freely moving small animals is essential when investigating pathologies involving raised ICP, such as stroke and traumatic brain injury. The current method of measuring chronic ICP in small animals such as rats, is based on using a commercially available fluid filled pressure catheter telemetry system from Data Sciences International. The telemetry implant is secured on top of the animal's head in a cut 3cc syringe body along with tubing to interface with the fluid filled catheter. This provides useful data but it requires extensive assembly of various tubing and external implant housing. In addition, the most serious drawback for this method is the fluid filled pressure sensor which is prone to artifacts associated with motion due to catheter bending and barostatic effects. We have developed a new method to measure ICP which is based on a biotelemetry system that uses a Millar based solid-state pressure sensor (EG2-V0S1T, Endosomatic Systems Inc, Davis, CA). The sensor is secured on the skull as shown on the diagram and the complete assembly of pressure catheter, implant and battery is tunneled subcutaneously. The ICP probe consists of a specially designed absolute pressure Millar 3F catheter that is only 15mm long with a very flexible cable leading to the implant. This ensures that head movements do not cause motion artifacts due to catheter stiffness.
An Efficient Test for Product States with Applications to Quantum Merlin-Arthur Games (2010)

We give a test that can distinguish efficiently between product states of n quantum systems and states which are far from product. If applied to a state |φ) whose maximum overlap with a product state is 1- ε, the test passes with probability 1-Θ(ε), regardless of n or the local dimensions of the individual systems. The test uses two copies of |φ). We prove correctness of this test as a special case of a more general result regarding stability of maximum output purity of the depolarising channel. A key application of the test is to quantum Merlin-Arthur games with multiple Merlins, where we obtain several structural results that had been previously conjectured, including the fact that soundness amplification is possible and that two Merlins can simulate many Merlins: QMA(k)=QMA(2) for k ≥ 2. Building on a previous result of Aaronson et al, this implies that there is an efficient quantum algorithm to verify 3-SAT with constant soundness, given two unentangled proofs of Õ(√n) qubits. Among other consequences, this result implies complexity-theoretic obstructions to finding a polynomial-time algorithm to determine separability of mixed quantum states, even up to constant error, and also to proving "weak" variants of the additivity conjecture for quantum channels. Finally, our test can also be used to construct an efficient test for determining whether a unitary operator is a tensor product, which is a generalisation of classical linearity testing.
The timing of phasic transmitter release is Ca <sup>2+</sup> -dependent and lacks a direct influence of presynaptic membrane potential (2003)

Ca2+ influx through voltage-gated Ca2+ channels and the resulting elevation of intracellular Ca2+ concentration, [Ca2+]i, triggers transmitter release in nerve terminals. However, it is controversial whether in addition to the opening of Ca2+ channels, membrane potential directly affects transmitter release. Here, we assayed the influence of membrane potential on transmitter release at the calyx of Held nerve terminals. Transmitter release was evoked by presynaptic Ca2+ uncaging, or by presynaptic Ca2+ uncaging paired with presynaptic voltage-clamp depolarizations to +80 mV, under pharmacological block of voltage-gated Ca2+ channels. Such a change in membrane potential did not alter the Ca2+ dependence of transmitter release rates or synaptic delays. We also found, by varying the amount of Ca2+ influx during Ca2+ tail-currents, that the time course of phasic transmitter release is not invariant to changes in release probability. Rather, the time difference between peak Ca2+ current and peak transmitter release became progressively shorter with increasing Ca2+ current amplitude. When this time difference was plotted as a function of the estimated local [Ca2+]i at the sites of vesicle fusion, a slope of approximately 100 micros per 10 microM [Ca2+]i was found, in reasonable agreement with a model of cooperative Ca2+ binding and vesicle fusion. Thus, the amplitude and time course of the [Ca2+]i signal at the sites of vesicle fusion controls the timing and the amount of transmitter release, both under conditions of brief periods of Ca2+ influx, as well as during step-like elevations of [Ca2+]i produced by Ca2+ uncaging.

Employing the Hand as an Interface Device (2006)

We propose algorithms and applications for using the hand as an interface device in virtual and physical spaces. In virtual drawing, by tracking the hand in 3-D and estimating a virtual plane in space, the intended drawing of user is recognized. In a virtual marble game, the instantaneous orientation of the hand is simulated to render a graphical scene of the game board. Real-time visual feedback allows the user to navigate a virtual ball in a maze. In 3-D model construction, the system tracks the hand motion in space while the user is traversing edges of a physical object. The object is then rendered virtually by the computer. These applications involve estimating the 3-D absolute position and/or orientation of the hand in space. We propose parametric modelling of the central region of the hand to extract this information. A stereo camera is used to first build a preliminary disparity map of the hand. Then, the best fitting plane to the disparity points is computed using robust estimation. The 3-D hand plane is calculated based on the disparity plane and the position and orientation parameters of the hand. Tracking the hand region over a sequence of frames and coping with noise using robust modelling of the hand motion enables estimating the trajectory of the hand in space. The algorithms are real-time and experiments are presented to demonstrate the proposed applications of using the hand as an interface device.
B207 Digital Specklegram Tomography for Reconstruction of Transient Three-Dimensional Density Distributions (2000)

Transient and asymmetric density distributions have been investigated by digital specklegram tomography. Multiple CCD images captured movements of speckles in three angles of view simultaneously because the flows were asymmetric and transient. The speckle movements between no flow and downward carbon dioxide flow from a circular small opening with a vertical partition have been calculated by a cross-correlation tracking method so that those distances can be transferred to deflection angles of laser rays for density gradients. The transient three-dimensional density fields have been reconstructed from the deflection angles by a tomography method.

Nanowire Photonic Circuit Elements (2004)

We report an approach for guiding and manipulating light on sub-wavelength scales using active nanowire waveguides and devices. Quantitative studies of cadmium sulfide (CdS) nanowire structures show that light propagation takes place with only moderate losses through sharp and even acute angle bends. In addition, measurements demonstrate that efficient injection into and modulation of light through nanowire waveguides are achievable in active devices. The ability to inject, guide, and manipulate light on a sub-wavelength scale using nanowire components that can be assembled into integrated structures represents a promising pathway towards integrated nanoscale photonic systems.
On the exact recovery of cumulants (2002)

The importance of higher-order statistics (HOS) is clearly reflected in their increasingly wide applicability. However, because of the high dimensionality involved, the digital estimation of HOS is still plagued by heavy computational loads which tend to severely reduce the potential for real-time applications. This paper proposes a solution to this problem, based on a successful exact moments recovery (EMR) theory which makes it possible to exploit the attractive practical advantages of 1-bit quantization schemes while avoiding their associated large quantization errors. Two new theorems on the variance aspects of 3 unbiased linear sample moment estimators are also presented. Finally, some simulation results on the recovery of cumulants, which are in very good agreement with the theory, are included.
Semantic Web for manufacturing Web services (2003)

Automatic Web service discovery and execution is receiving a lot of attention within the Web applications community. Web services aim to reduce the collaboration costs and increase productivity by automating the enterprise processes. In this paper, we explore and illustrate the potential use of semantic Web in the context of manufacturing services. In particular, we identify benefits of explicitly encoding semantics of the manufacturing Web services.

Intravenous (i.v.) busulfan (Bu) plus melphalan (Mel) is a well-tolerated preparative regimen for stem cell transplantation (SCT) in patients (pts) with advanced lymphoid malignancies (2006)

High dose chemotherapy and SCT is an accepted treatment option for pts with relapsed lymphoid malignancies. However, relapse remains a significant issue for pts with advanced disease. A double alkylating regimen of Bu and Mel has been suggested as an effective and myeloablative pre-transplant conditioning regimen. Historically, oral Bu was used and the combination resulted in considerable mucositis and VOD. Recently, an i.v. formulation of Bu has been developed that has less pharmacokinetic variability. We are investigating the safety and efficacy of i.v. Bu-Mel in pts with lymphoid malignancies undergoing auto- or allo-SCT. Patients and Methods: The conditioning regimen consists of i.v. Bu 130 mg/m2 over 3 hours daily for 4 days, either as a fixed dose per BSA, or to target an average daily AUC of 5000 mMol-min ± 12% determined by a test dose of i.v. Bu at 32 mg/m2 given 48 hours prior to the high dose regimen. After the 4 daily Bu doses, there is a rest day, followed by 2 daily doses of Mel at 70 mg/m2. Stem cells are infused the following day. Dilantin is administered for seizure prophylaxis. GVHD prophylaxis consists of tacrolimus and methotrexate for pts receiving allo-SCT. Results: Twenty-five pts (17 M/8 F) with median age 40 years (range 19–65): MM (n = 5), NHL (n = 5), HD (n = 13), ALL (n = 2). Median number of prior chemotherapy regimens was 3 (range 1–8). At study entry, 2 pts were in CR1; 23 were in relapse: refractory (n = 3), chemo-sensitive first relapse (n = 9), and beyond first relapse (n = 11). Engraftment, GVHD, and toxicity data are shown in Table 1. Grades I or II mucositis was the most common regimen-related toxicity. Of note, there were no cases of VOD; reversible hyperbilirubinemia, grade II (n = 2) and grade III (n = 1), was observed in 3 pts receiving allo-SCT. All allo-SCT pts had 100% donor chimerism by day 30. Twenty pts had i.v. Bu delivered per test dose guidance; 5 pts received fixed dose Bu at 130 mg/m2. The median daily systemic Bu exposure was 4867 μMol-min. Conclusions Intravenous Bu-Mel is well tolerated and enables prompt neutrophil and platelet engraftment. Individualized PK-directed dosing of i.v. Bu is feasible, and likely contributes to the low toxicity profile of this regimen. Longer follow-up is needed to assess disease control (Table 1).
