Effects of amfonelic acid, alpha-methyltyrosine, Ro 4-1284 and haloperidol pretreatment on the depletion of striatal dopamine by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine in mice. (1985)

1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) given in 4 daily s.c. injections to mice resulted in marked depletion of striatal dopamine, 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) 1 week after the last dose. Pretreatment of mice with alpha-methyltyrosine or Ro 4-1284 to deplete dopamine prior to MPTP injection did not prevent these effects of MPTP, nor did pretreatment with haloperidol, a dopamine receptor antagonist. The depletion of striatal dopamine by MPTP in mice therefore differs from the persistent depletion of striatal dopamine by amphetamine in iprindole-treated rats, which is prevented by pretreatment with either alpha-methyltyrosine or haloperidol. The depletion of dopamine, DOPAC and HVA in mouse striatum by MPTP was totally prevented by pretreatment with amfonelic acid, an inhibitor of dopamine uptake. This finding suggests that these effects of MPTP, like those of amphetamine in iprindole-treated rats, are dependent upon a functional transport system into the dopamine neuron.
The forward discharge converter (FDC): a general solution to obtain soft-switching in any power converter (2003)

It is noted that soft switching obtained by means of C or LC snubbers and forward discharge power converter forward zero-current-switched QRC like an energy recovery network replaces a simple MOSFET switch without changes in power topology (one or multiple switches) and control circuit (one drive signal for each is holding up). All control strategies (fixed or variable frequency and current of voltage mode) are possible, i.e., pulse-width-modulated (PWM) converters become low switching loss topologies, and high frequency is feasible.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Interruptions and delays in a capital project (1997)

A huge amount of work has been done to find better ways of managing projects. But most projects still finish late and cost more than expected. This article looks at the reasons for delays in one capital project. Among the contributing factors were uncertainties about times, optimism in the planning stage, a lack of commitment to schedules, and an assumption that project managers could overcome any problems they met during execution. One important feature of this project was a planned break during the execution. Planners did not properly allow for the disruption this break would cause, and the project was soon eight weeks behind schedule.
The role of pudendal nerve innervation in female pelvic floor function (1994)

The assessment of motor conduction along the pudendal nerve is an accurate objective measure of pudendal nerve function. Measurement of its latency (that is the time interval between electrical stimulation of the nerve and induced contraction of the external anal sphincter) has been demonstrated to be abnormally long following vaginal delivery, particularly if the delivery was associated with a heavy fetus or a prolonged second stage of labor. The significance of pudendal neuropathy and its relationship to abnormal degrees of descent of the pelvic floor have also been examined in this review.
Intravesical onabotulinumtoxinA injections for refractory painful bladder syndrome. (2012)

Intravesical onabotulinumtoxinA injection appears to be a safe and effective therapeutic option for analgesia and increased bladder capacity for patients with IC/PBS. INSTITUTIONAL REVIEW: This study was approved by the Institutional Review Board of the Buddhist Tzu-chi General Hospital.
Long-term experience with intraoperative microrecording during DBS neurosurgery in STN and GPi (2010)

MER facilitates the selection of the final electrode location in STN-DBS and GPi-DBS, and based on the observed MER activity, a pre-selection could be made as to which channel would be the best candidate for macro-test stimulation and at which depth should be stimulated. The choice of the final location is based on intraoperative test stimulation, and it is demonstrated that regularly it is not the central channel that is chosen for implantation. On average, the target as defined by MER activity intensity was in accordance with the MRI-based targets both for the STN and GPi. However, the position of the best MER activity did not necessarily correlate with the locus that produced the most beneficial clinical response on macroelectrode testing intraoperatively.
Combination biologics: 1 stone, 2 birds (2007)

The monoclonal antibody described by Lin and colleagues (anti-BR3) can both deplete B cells directly and block the B-cell survival factor BAFF. It thus achieves more profound biological effects in vivo, which may have therapeutic advantages.
Electromigration in Ion Bombardment (1977)

The behavior of insulator materials subjected to ion bombardment at elevated temperatures was investigated. Glasses at various temperatures up to the strain point and high temperature ceramic materials up to 600/sup 0/C were used. Charge incident on some of these specimens is conducted to the metal support by ionic conductivity through the specimen resulting in electromigration of alkali ion.
Capillary Imbibition and Gravity Segregation in Low IFT Systems (1991)

ABSTRACT The effect of reduced interfacial tension (IFT) on oil recovery by spontaneous imbibition and gravity segregation is investigated experimentally for a wide range of IFT’s in cores oriented vertically. The experimental results presented indicate that a crossover from capillary to gravity driven imbibition occurs. For cores with low permeability and high IFT between the wetting and nonwetting phases, capillarity initiates coun-tercurrent imbibition and oil is produced from all faces. For moderately low IFT’s and permeabilities above about 100 md, gravity segregation is the controlling mechanism. In this case, the rate of oil recovery may actually be greater for low IFT’s. Gravity induced imbibition is cocurrent (oil produced from the top face only), which helps prevent snap-off and entrapment and allows high total recoveries. In addition, data are presented that indicate that surface tension gradients arising from composition gradients can substantially increase or decrease the rate of imbibition depending on the direction of the surface tension gradient.
Globalisation and enterprise culture in developing economies: a preliminary assessment (2005)

Globalisation and enterprise culture in developing economies: a preliminary assessment The global environment has been susceptible to changes for centuries. In recent years, the process which have moved the world towards &quot;global interdependence and exchange &apos; have been known as globalisation (Mazuri, 2002). Globalisation led to changes in the social and economic environment, and in both developed and developing countries experienced opportunities for economic growth. This was an uneven process but provided opportunities for new entrepreneurial activities. According to Schumpeter (1934), entrepreneurial activities are the result of combinations from discovering new markets, new raw materials, new suppliers and new production methods. These entrepreneurial activities would enable opportunities to be exploited and also contribute to economic growth. This encouraged developed and developing countries to acknowledge the relevance of entrepreneurial activity and its role in developing a economy effective enough to compete in a global environment. In the past, entrepreneurial activities developed naturally within the existing market environment. With the opportunities and threats presented by globalisation, governments realised the need to stimulate an increased level of entrepreneurial activity to counteract the impact of global competition in their
Opioid modulation of the discriminative stimulus effects of cocaine (1994)

Modulation of the discriminative stimulus effects of cocaine by the µ agonist morphine, the kappa agonist U 50, 488, and the delta agonist BW 373U86 was investigated in squirrel monkeys using a two-lever drug discrimination procedure. Monkeys initially were trained to discriminate intramuscular injections of 0.3 or 0.56mg/kg cocaine from vehicle and subsequently retrained to discriminate a 3- to 5.6-fold lower dose of cocaine (0.1 or 0.18mg/kg). After retraining, dose-response functions for the discriminative stimulus effects of cocaine were shifted to the left and ED(50) values were reduced 2- to 6-fold compared to values obtained with the higher training doses. In drug substitution experiments, morphine (0.03-1.0mg/kg), U 50,488 (0.1-3.0mg/kg) and BW 373U86 (0.001-0.1mg/kg) did not reproduce the discriminative stimulus effects of the low training doses of cocaine, although U 50,488 engendered a majority of responses on the cocaine-associated lever in two of three monkeys. In drug interaction experiments, pretreatment with morphine (0.3mg/kg) potentiated the discriminative stimulus effects of the low training doses of cocaine such that the cocaine dose-response functions were shifted to the left and ED(50) values were reduced 3- to 7-fold. Pretreatment with U 50,488 (0.3mg/kg), on the other hand, attenuated the discriminative stimulus effects of the low training doses of cocaine such that the cocaine dose-response functions were shifted to the right and ED(50) values were increased approximately 4-fold. The cocaine-modulating effects of morphine and U 50,488 in these experiments were qualitatively similar to those observed previously when the monkeys were trained to discriminate higher doses of cocaine. In contrast to the effects of the µ and kappa agonists, pretreatment with BW 373U86 (0.01 or 0.03mg/kg) did not systematically alter the discriminative stimulus effects of cocaine regardless of training dose.
Use of Serial Analysis of Gene Expression Technology to Reveal Changes in Gene Expression in Arabidopsis Pollen Undergoing Cold Stress   (2003)

We have characterized the global gene expression patterns of Arabidopsis pollen using Serial Analysis of Gene Expression (SAGE). A total of 21,237 SAGE tags were sequenced and 4,211 unique tags were identified. Interestingly, the number of unique tags in pollen was low compared with the SAGE library of the leaf constructed on a similar scale. The transcript profiles of pollen reflect accurately the characteristics of pollen as a reproductive organ. Functional classification of the expressed genes reveals that those involved in cellular biogenesis such as polygalacturonase, pectate lyase, and pectin methylesterase make up more than 40% of the total transcripts. However, genes involved in energy and protein synthesis, which are prevalent in leaves, were expressed at a relatively low level. The expression level of the great majority of transcripts was unaffected by cold treatment at 0 degrees C for 72 h, whereas pollen tube growth and seed production were substantially reduced. Interestingly, many genes thought to be responsible for cold acclimation such as COR, lipid transfer protein, and beta-amylase, that are highly induced in Arabidopsis leaves, were only expressed at their normal level or weakly induced in the pollen. The expression patterns of the cold-responsive transcripts identified by SAGE were confirmed by microarray analysis. Our results strongly suggest that poor accumulation of proteins that play a role in stress tolerance may be why Arabidopsis pollen is cold sensitive.

Epidural spinal-cord stimulation facilitates recovery of functional walking following incomplete spinal-cord injury (2004)

We investigated a novel treatment paradigm for developing functional ambulation in wheelchair-dependent individuals with chronic, incomplete spinal-cord injury. By coordinating epidural stimulation of the dorsal structures of the spinal cord with partial weight bearing treadmill therapy, we observed improvement in treadmill and over-ground ambulation in an individual with chronic incomplete tetraplegia. The application of partial weight-bearing therapy alone was not sufficient to achieve functional ambulation over ground, though treadmill ambulation improved significantly. Combining epidural spinal-cord stimulation (ESCS, T10-T12 vertebral levels) with partial weight-bearing therapy resulted in further improvement during treadmill ambulation. Moreover, the combination of therapies facilitated the transfer of the learned gait into over ground ambulation. Performance improvements were elicited by applying continuous, charge-balanced, monophasic pulse trains at a frequency of 40-60 Hz, a pulse duration of 800 micros, and an amplitude determined by the midpoint (50%) between the sensory and motor threshold values. The participant initially reported a reduction in sense of effort for over ground walking from 8/10 to 3/10 (Borg scale), and was able to double his walking speed. After several weeks of over ground training, he reached maximum walking speeds of 0.35 m/s, and was able to ambulate over 325 m. We propose that ESCS facilitated locomotor recovery in this patient by augmenting the use-dependent plasticity created by partial weight bearing therapy. Confirmation of these promising results in a controlled study of groups of spinal-cord-injured subjects is warranted.

Cryptates: inclusion complexes of macropolycyclic receptor molecules (1978)

Abstract
Structural Studies on NaFePO<sub>4</sub> as a Cathode Material for Na<sup>+</sup>/Li<sup>+</sup> Mixed-Ion Batteries (2011)

NaFePO4 has been synthesized via the Pechini process and the resulting sample was characterized using X-ray diffraction and thermogravimetric analysis. Electrochemical properties have been investigated for possible application as cathode in sodium-ion battery. This sample was made into electrode in a coin cell with LiPF 6 in organic carbonates as the electrolyte and lithium metal as the counter electrode. Charge/discharge behavior, cyclic voltammetry, and in-situ frequency response analysis were performed. The results obtained demonstrate constant or increase in capacity and consistently low internal resistance with consecutive cycles.
Gastrin promotes human colon cancer cell growth <i>via</i> CCK‐2 receptor‐mediated cyclooxygenase‐2 induction and prostaglandin E<sub>2</sub> production (2005)

The present study investigates the effects of gastrin-17 on human colon cancer HT-29 cells to examine whether gastrin receptor (CCK-2), cyclooxygenase (COX-1, COX-2) isoforms and prostaglandin receptor pathways interact to control cell growth. Reverse transcription (RT)-polymerase chain reaction (PCR) analysis demonstrated that HT-29 cells are endowed with the naive expression of CCK-2 receptor (short splice variant), COX-1, COX-2 and prostaglandin EP(4) receptor, but not gastrin. Gastrin-17 significantly promoted cell growth and DNA synthesis. Both these stimulating effects were abolished by L-365,260 or GV150013 (CCK-2 receptor antagonists), but were unaffected by SC-560 (COX-1 inhibitor). L-745,337 (COX-2 inhibitor) or AH-23848B (EP(4) receptor antagonist) partly reversed gastrin-17-induced cell growth, while they fully antagonized the enhancing action on DNA synthesis. HT-29 cells responded to gastrin-17 with a significant increase in prostaglandin E(2) release. This enhancing effect was completely counteracted by L-365,260, GV150013 or L-745,337, while it was insensitive to cell incubation with SC-560. Exposure of HT-29 cells to gastrin-17 was followed by an increased phosphorylation of both extracellular regulated kinases (ERK-1/ERK-2) and Akt. Moreover, gastrin-17 enhanced the transcriptional activity of COX-2 gene promoter and stimulated COX-2 expression. These latter effects were antagonized by L-365,260 or GV150013, and could be blocked also by PD98059 (inhibitor of ERK-1/ERK-2 phosphorylation) or wortmannin (inhibitor of phosphatidylinositol 3-kinase). Analogously, gastrin-17-induced prostaglandin E(2) release was prevented by PD98059 or wortmannin. The present results suggest that (a) in human colon cancer cells endowed with CCK-2 receptors, gastrin-17 is able to enhance the transcriptional activity of COX-2 gene through the activation of ERK-1/ERK-2- and phosphatidylinositol 3-kinase/Akt-dependent pathways; (b) these stimulant actions lead to downstream increments of COX-2 expression, followed by prostaglandin E(2) production and EP(4) receptor activation; (c) the recruitment of COX-2/prostaglandin pathways contributes to the growth-promoting actions exerted by gastrin-17.

Problem of Steal from Motor Vehicle in New South Wales, The (2008)

The recorded incidence of steal from a motor vehicle increased by 4.3 percent in New South Wales, between 2005/06 and 2006/07. Money and registration plates are the items most commonly stolen. The increase in steal from motor vehicle incidents was limited to the statistical subdivisions of: Inner Sydney; Inner Western Sydney; Central Western Sydney; Blacktown; Central Northern Sydney and Lower Northern Sydney. More that 70 percent of the total NSW increase occurred in Inner Sydney and Central Western Sydney. Despite most steal from motor vehicle incidents involving cars parked in public streets, the increase has been largely confined to car parks. An analysis of victimisation in individual car parks found that a large number of incidents were concentrated in a small number of car parks. In Inner Sydney, ten car parks accounted for six percent of all incidents (569 incidents). These ten car parks accounted for 27 percent of the increase in Inner Sydney and 12 percent of the statewide increase. In Central Western Sydney, seven percent of all steal from motor vehicle incidents (256 incidents) occurred in a single car park. This car park was responsible for 30 percent of the increase in Central Western Sydney and eight percent of the statewide increase.

Invited Review: The Search is on: Finding Accurate Molecular Markers of Male Fertility (2001)

Diagnosis of the fertility potential of a semen sample is essential for consistently high reproductive efficiency. The use of subfertile or infertile semen can have devastating consequences for those selling or using the semen. Therefore it is crucial to develop and use accurate diagnostic tests to determine the fertility of males and of individual semen samples. These diagnostic tests must be economically practical and provide consistent results. The goal of this review is to explore areas of fertility diagnostic research, including what we have termed functional and molecular tests, and consider the accuracy of each test. In this article, literature from several species is cited, and it is noteworthy that each diagnostic test may not be valuable in all species. Multiple functional and molecular tests will likely be needed to effectively characterize male fertility in each species.
Pseudo noise sequences for engineers (1996)

Pseudo random binary sequences (PRBSs), also known as pseudo noise (PN), linear feedback shift register (LFSR) sequences or maximal length binary sequences (m-sequences) are widely used in digital communications and the theory involved has been treated extensively in the literature. However, a practising engineer is interested in the fundamentals and the applications of PN sequences, and the methods of generating them with hardware. This paper presents, without the mathematical rigours, some of the interesting characteristics and the use of these characteristics in the generation and acquisition of PN sequences. The series-parallel method of generating PN sequences at high speeds with low-speed devices, which is of interest to hardware designers, is discussed. Some applications of PN sequences in communications and instrumentation are discussed.
