A Mouse Model of Graded Contusive Spinal Cord Injury (1998)

A mouse model of spinal cord injury (SCI) could further increase our basic understanding of the mechanisms involved in injury and recovery by taking advantage of naturally-occurring and genetically engineered mutations available in mice. We have, therefore, investigated whether methods used to produce and evaluate graded experimental contusive SCI in the rat could be modified to produce a mouse model of traumatic SCI. C57BL6 mice were anesthetized with 2,2,2-tribromoethanol and a restricted laminectomy performed at the T8 vertebral level. The spinal column was stabilized and a weight drop technique used to produce contusive injury. Experimental groups were distinguished by the amount of weight or the height from which the weight was dropped onto an impounder resting on the dura (1 g x 2.5 cm, 2 g x 2.5 cm, 3 g x 2.5 cm, and 3 g x 5.0 cm). Functional deficits over time were examined up to 28 days after SCI by testing hindlimb reflex responses and coordinated motor function. Chronic lesion histopathology was evaluated by light microscopy and analyzed with morphometric techniques. All groups demonstrated profound functional deficits after injury followed by gradual recovery. Recovery correlated with the weight dropped and percent of white matter spared that was 41.3+/-6.0% (mean +/- SEM) in the 2 g x 2.5 cm group and 24.3+/-5.0% in the 3 g x 2.5 cm group. A replicate experiment confirmed reproducibility of the injury. This new mouse model of contusive SCI could pave the way for in vivo studies of the effect of genetic modifications produced by specific mutations on injury and recovery processes after spinal cord trauma.
Interviews with child I, child J, and child L (1990)

Twenty‐eight former students at the Speyer School were interviewed by the author of this report. Three children from the group are portrayed through their interview protocols. The female students here considered their children as their major accomplishment, whereas the male cited his work in mathematics. Post‐Speyer education focused on family situations for the females from the school. All three alumni maintained a close tie with education, either as teachers or as board of education members.
Nonlinear 3D Face Morphable Model (2018)

As a classic statistical model of 3D facial shape and texture, 3D Morphable Model (3DMM) is widely used in facial analysis, e.g., model fitting, image synthesis. Conventional 3DMM is learned from a set of well-controlled 2D face images with associated 3D face scans, and represented by two sets of PCA basis functions. Due to the type and amount of training data, as well as the linear bases, the representation power of 3DMM can be limited. To address these problems, this paper proposes an innovative framework to learn a nonlinear 3DMM model from a large set of unconstrained face images, without collecting 3D face scans. Specifically, given a face image as input, a network encoder estimates the projection, shape and texture parameters. Two decoders serve as the nonlinear 3DMM to map from the shape and texture parameters to the 3D shape and texture, respectively. With the projection parameter, 3D shape, and texture, a novel analytically-differentiable rendering layer is designed to reconstruct the original input face. The entire network is end-to-end trainable with only weak supervision. We demonstrate the superior representation power of our nonlinear 3DMM over its linear counterpart, and its contribution to face alignment and 3D reconstruction.
Optimal location and capacity of emergency cleanup equipment for oil spill response (1997)

Myopic planning and tactical decision-making with regards to oil spill events result in severely inefficient cleanup efforts with high fixed, operating and cleanup/damage costs. We propose an integrated framework that addresses some important strategic issues such as determining the optimal location and capacity of cleanup equipment, taking into account their post event implications. We develop a linear integer programming model, exhibit its complexity and propose a solution method by solving a relaxation of the original problem. Realistic examples applied to the Florida peninsula are presented.
Sensitivity Analysis of Parasitic Effects in Resistance Terminated LC Two-Ports (1967)

Properties of classical sensitivity functions in resistance-terminated LC two-ports are examined and utilized to study the effects of element variations, incidental dissipation, and stray terminations on transmission characteristics. The results show that phase lag in such networks increases monotonically with the magnitude of any <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</tex> or <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">C</tex> as well as with frequency. Further, they enable the formulation of a number of bounds on errors in transmission characteristics induced by various parasitic phenomena, including the effects of nonuniformly distributed loss when inductors and capacitors have dissipation factors less than fixed constants <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">\bar{d}_L</tex> . and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">\bar{d}_C</tex> , respectively. The bounds are invariant for all equivalent twoport realizations and demonstrate the limitations imposed on network sensitivity performance by design specifications.
Effect of appliance reactivation after decay of initial activation on osteoclasts, tooth movement, and root resorption. (1999)

Clinical orthodontists frequently reactivate appliances following decay. Studies of tooth movement and tissue responses following reactivations indicate that linear tooth movement and rapid recruitment of osteoclasts can be achieved if reactivation is timed to coincide with the latter part of the bone remodeling cycle initiated by the first activation. Both can be delayed if reactivations are timed for the early part of the previous cycle. The objective of this study was to examine tooth movement, root resorption, and osteoclast recruitment following appliance reactivation after the first activation had decayed. Bilateral orthodontic appliances were activated with 40 cN in 144 rats to mesially tip the maxillary molars. After 16 days, rats were randomized into two groups of 72. In group 1, appliances were reactivated in precisely the same manner as the first activation. In group 2, appliances were sham-reactivated. Rats were sacrificed at 1, 3, 5, 7, 10, and 14 days. Orthodontic movement was measured cephalometrically; changes in osteoclasts and root resorption were assessed at both compression and tension sites histomorphometrically; tartrate-resistant acid phosphatase (TRAP) was measured in alveolar bone and serum biochemically. Orthodontic tooth movement was linear in group 1, but osteoclasts required 3 to 5 days to appear. There were no group- or time-related differences in root resorption. Bone TRAP levels were elevated in both groups but dropped significantly (p<0.01) in group 2 at day 7. Appliance reactivations that followed decay of the first activation produced efficient tooth movement without increased risk of root resorption, but these changes were not accompanied by rapid osteoclast recruitment at compression sites. Timing appliance reactivations for the latter portion of the previous bone remodeling cycle could have significant clinical advantages because the delay period seen in tooth movement following a single activation or short-term reactivation can be avoided.

PKA delivery to the distal lung air spaces increases alveolar liquid clearance after isoproterenol-induced alveolar epithelial PKA desensitization (2005)

Isoproterenol (Iso) infusion for 48 h in rats decreases the ability of beta-adrenoceptor (beta-AR) agonists to increase alveolar liquid clearance (ALC). An impairment in protein kinase A (PKA) function appears to be critical in producing the desensitized ALC response. To test this hypothesis, we used a novel protein delivery reagent (Chariot, Active Motif) to deliver either the PKA catalytic subunit or the PKA holoenzyme to the distal lung epithelium of Iso-infused rats (400 microg.kg(-1).h(-1), 48 h). After this infusion, ALC was measured by mass balance over 2 h. ALC in Iso-infused rats was 27.9% (SD 5.8) of instilled volume absorbed. Delivery of the catalytic PKA subunit to Iso-infused rats increased ALC to 47.7% (SD 8.9) (P < 0.05). ALC in Iso-infused rats delivered the inactive PKA holoenzyme [29.6% (SD 2.5)] was not increased above baseline values. Subsequent holoenzyme activation by intravenous infusion of the stable cAMP analog Sp-8-Bromo-cAMPS increased ALC to 41.7% (SD 8.8) (P < 0.05). Immunohistochemical localization of Chariot-delivered PKA revealed staining in the alveolar and distal airway epithelium. These data indicate that protein delivery reagents can be used to rapidly deliver biologically active proteins to the distal lung epithelium and that PKA desensitization may be an important rate-limiting event in the development of Iso-induced desensitization of the alveolar epithelial beta-AR signaling pathway.

Role of a Capacitation-Related Protein on Some Sperm Functional Parameters (2002)

In previous studies a series of Mabs against boar capacitated sperm have been produced. One of these Mabs--4B12--was found to recognize a surface membrane-associated protein located in the acrosome portion of the spermatozoa that became accessible to antibody after capacitation. In biological experiments it was shown that Mab 4B12 significantly inhibited boar sperm-porcine ZP binding. In attempts to investigate the mechanisms by which Mab 4B12 affected sperm-ZP binding, the role of the cognate protein on some functional parameters such as sperm motility and ability of the capacitated spermatozoa to undergo AR was studied. Experimental models of premature AR and AR physiologically induced with ZP were applied to study the effect of Mab 4B12 on boar sperm AR using PSA staining to estimate the acrosome-reacted state of spermatozoa. Sperm motility characteristics were determined by the time-exposure photokinesigraphic method. The results obtained in the present study, together with previously established inhibition of sperm-ZP binding by Mab 4B12, documented the participation of the 4B12 protein in primary sperm-ZP binding. The protein is not connected with sperm motility and secondary sperm-ZP binding.

The Medial Rotation total knee replacement (2009)

We describe the survivorship of the Medial Rotation total knee replacement (TKR) at ten years in 228 cemented primary replacements implanted between October 1994 and October 2006, with their clinical and radiological outcome. This implant has a highly congruent medial compartment, with the femoral component represented by a portion of a sphere which articulates with a matched concave surface on the medial side of the tibial insert. There were 78 men (17 bilateral TKRs) and 111 women (22 bilateral TKRs) with a mean age of 67.9 years (28 to 90). All the patients were assessed clinically and radiologically using the American Knee Society scoring systems. The mean follow-up was for six years (1 to 13) with only two patients lost to follow-up and 34 dying during the period of study, one of whom had required revision for infection. There were 11 revisions performed in total, three for aseptic loosening, six for infection, one for a periprosthetic fracture and one for a painful but well-fixed replacement performed at another centre. With revision for any cause as the endpoint, the survival at ten years was 94.5% (95% CI 85.1 to 100), and with aseptic loosening as the endpoint 98.4% (95% CI 93 to 100). The mean American Knee Society score improved from 47.6 (0 to 88) to 72.2 (26 to 100) and for function from 45.1 (0 to 100) to 93.1 (45 to 100). Radiological review failed to detect migration in any of the surviving knees. The clinical and radiological results of the Medial Rotation TKR are satisfactory at ten years. The increased congruence of the medial compartment has not led to an increased rate of loosening and continued use can be supported.
Treatment of Volatile Organic Compounds From Gas Streams Using a Three-Phase Circulating-Bed Biofilm Reactor. (2000)

This study focuses on the biofilm kinetics of removing benzene, toluene, and p-xylene (BTX) from gas streams in a three-phase circulating-bed reactor using porous carriers. In the biofilm reactor, gas-liquid equilibrium existed for BTX, but not for oxygen. Oxygen was consumed as a cosubstrate in the oxygenation reactions and the terminal electron acceptor during respiration. When toluene was the sole substrate, oxygen mostly controlled its removals, and toluene inhibition mostly controlled the removals of the toluene intermediate. With increased toluene or decreased oxygen loading, more toluene intermediate was removed inside the biofilm, and the intermediate mass flux changed in direction from out-of to into the biofilm. The mass transfer resistance in the biofilm relieved the intermediate from toluene inhibition. However, higher biofilm accumulation showed adverse effects on reactor performance due to increased demand for oxygen for respiration. The suspended biomass contributed to the removals of toluene and its intermediate and played its most important role when oxygen limitation was significant When toluene/benzene or toluene/p-xylene were removed simultaneously, their inhibition forced more volatile organic compounds to be removed inside the biofilm, where mass transfer resistance relieved the inhibition effects. The removal efficiencies for the lower-concentration compound were smaller.
Purification of GP-83, a glycoprotein secreted by the human epididymis and conjugated to mature spermatozoa (2000)

Epididymal secretions are critical for mammalian spermatozoa to acquire both forward motility and an ability to recognize and penetrate oocytes. Previous studies identified two glycoproteins, GP-83 and GP-39, which were secreted by the human epididymis and may be related to maturation of sperm function. In this study, GP-83 was purified from human seminal fluid by DEAE–ion exchange, gel filtration chromatography and preparative gel elution. The isoelectric point (pI) of purified GP-83 was 6.57. Monospecific antiserum to GP-83 was induced in male New Zealand rabbits and confirmed on immunoblots. GP-83 was found in fluid, tissue and sperm extracts of corpus and cauda epididymis, but not in the caput. Immunohistochemical localization identified GP-83 in the luminal contents and in the supranuclear region and cell membrane of principal cells of the corpus and cauda epididymis. GP-83 was found on the anterior acrosome in ejaculated spermatozoa, and shifted to the equatorial region after capacitation and the acrosome reaction.
Solution-phase-peptide synthesis via the group-assisted purification (GAP) chemistry without using chromatography and recrystallization (2013)

The solution phase synthesis of N-protected amino acids and peptides has been achieved through the Group-Assisted Purification (GAP) chemistry by avoiding disadvantages of other methods in regard to the difficult scale-up, expenses of solid and soluble polymers, etc. The GAP synthesis can reduce the use of solvents, silica gels, energy and manpower. In addition, the GAP auxiliary can be conveniently recovered for re-use and is environmentally friendly and benign, and substantially reduces waste production in academic labs and industry.

Pulse laser generation in several Er3+,Yb3+:glasses thermally bonded with Co2+:MgAl2O4 was achieved. Peak power in the range of 1.83–7.68 kW with pulse duration between 2.9 and 4.2 ns and energy up to 24 μJ was obtained. The output characteristics for different transmissions of the output couplers were investigated. To show the improvements gained by the thermal bonding procedure, a comparison of thermally bonded and unbonded samples was done in terms of generation efficiency, peak power, beam quality, generated spectra and pulse to pulse jitter.
An Active Sound Absorber With Porous Plate (1984)

An active equivalent of the λ/4 resonance absorber with a porous plate or foil of flow resistance ρc is described. The porous layer is backed by a loudspeaker driven such that zero sound pressure is maintained in the air gap between foil and speaker. The simultaneous control of magnitude and phase has been achieved in analog technique by a combination of open-loop and closed-loop control, utilizing single sideband modulation of the compensation signal with a weak infrasonic auxiliary signal. The on-off ratio of the reflection coefficient reaches −60 dB for sinusoidal sound, and −20 dB for broadband noise.
