Generation of infrared surface plasmon resonances with high refractive index sensitivity utilizing tilted fiber Bragg gratings (2007)

We demonstrate the use of tilted fiber gratings to assist the generation of localized infrared surface plasmons with short propagation lengths and a sensitivity of dlambda/dn = 3,365 nm in the aqueous index regime. It was also found that the resonances could be spectrally tuned over 1,000 nm at the same spatial region with high coupling efficiency (in excess of 25 dB) by altering the polarization of the light illuminating the device.
Directed Assembly of a Cylinder-Forming Diblock Copolymer: Topographic and Chemical Patterns (2010)

Using simulations of a coarse-grained model, we examine the ability of topographic and chemical patterns to direct the self-assembly of thin films of copolymers into a defect-free array of vertical cylinders. The topographic pattern is a trench where the diblock is confined, whereas the chemical pattern consists of spots that interact preferentially with the minority block. The self-assembly process is described with Monte Carlo simulations of the standard model of block copolymers. While fully three-dimensional, the simulated systems can include over a hundred domains. By analyzing top views and cross sections of thin films, it is possible to determine the degree of ordering and the properties of individual domains. First, the influence of confinement on ordering perfection is examined. By focusing on the influence of trench width and sidewall selectivity, one can identify conditions that yield defect-free arrays with a high reliability and for which domains exhibit a high degree of uniformity across the trench. Second, we consider chemical patterns. While patterns matching the block copolymer morphology and characteristic dimensions yield defect-free self-assembly, we study the tolerance of directed self-assembly against deviations from this optimal case. We first explore the effect of a mismatch between the spacing of the pattern and the diblock characteristic dimensions, and then we examine the interpolation of domains on an incomplete pattern, where half of the rows are missing. By introducing placement error in the position of the spots, we assess to what extent the diblock can rectify the noise of a substrate pattern. The results of simulations are discussed in the context of a variety of experimental observations.
Prolactin-immunoglobulin G complexes from human serum act as costimulatory ligands causing proliferation of malignant B lymphocytes. (1995)

Several lines of evidence indicate that immunoglobulin-bound prolactin found in human serum is not a conventional complex between an anti-prolactin antibody and prolactin but a different type of association of prolactin with the Fab portion of IgG heavy chains. The complex of prolactin with IgG was purified from serum by anti-human prolactin affinity chromatography and was shown to contain close to 1 mole of N epsilon-(gamma-glutamyl)lysine crosslinks per mole of complex, a characteristic feature in structures crosslinked by transglutaminase. Interestingly, the complex caused a proliferation of cells from a subset of patients with chronic lymphocytic leukemia, while it was inactive in a cell proliferation prolactin bioassay. By contrast, human prolactin stimulated the proliferation of cells in the bioassay but had no effect on the complex-responsive cells from the patients. Competition studies with prolactin and free Fc fragment of IgG demonstrated a necessity for engaging both the prolactin and the immunoglobulin receptors for proliferation. More importantly, competition for the growth response by free prolactin and IgG suggests both possible reasons for the slow growth of this neoplasm as well as avenues for control of the disease.
Female boxers: 'Sideshow freaks'? (2008)

Historically women's sporting activities in Australia have been marginalised. Relegated to the periphery, women's sports have had to endure with scant resources and support. In the traditionally 'masculine' sport of boxing, the public image of women in the ring is still not fully embraced despite women being active in professional boxing for more than a century.
Bipolar DNA Translocation Contributes to Highly Processive DNA Unwinding by RecBCD Enzyme (2005)

We recently demonstrated that the RecBCD enzyme is a bipolar DNA helicase that employs two single-stranded DNA motors of opposite polarity to drive translocation and unwinding of duplex DNA. We hypothesized that this organization may explain the exceptionally high rate and processivity of DNA unwinding catalyzed by the RecBCD enzyme. Using a stopped-flow dye displacement assay for unwinding activity, we test this idea by analyzing mutant RecBCD enzymes in which either of the two helicase motors is inactivated by mutagenesis. Like the wild-type RecBCD enzyme, the two mutant proteins maintain the ability to bind tightly to blunt duplex DNA ends in the absence of ATP. However, the rate of forward translocation for the RecB motor-defective enzyme is only approximately 30% of the wild-type rate, whereas for the RecD motor-defective enzyme, it is approximately 50%. More significantly, the processivity of translocation is substantially reduced by approximately 25- and 6-fold for each mutant enzyme, respectively. Despite retaining the capacity to bind blunt dsDNA, the RecB-mutant enzyme has lost the ability to unwind DNA unless the substrate contains a short 5'-terminated single-stranded DNA overhang. The consequences of this observation for the architecture of the single-stranded DNA motors in the initiation complex are discussed.
Stent-graft placement for wide-neck aneurysm of the vertebrobasilar junction. (2004)

We present a case in which a stent-graft was used to treat an aneurysm of the vertebrobasilar junction. According to our literature search, this is one of the first cases involving the intracranial placement of a stent-graft and the first case in which an aneurysm of the vertebrobasilar junction was treated in this manner. A stent-graft can be useful device for the neuroendovascular treatment of aneurysms in select patients.
Randomized, controlled trial of dextromethorphan/quinidine for pseudobulbar affect in multiple sclerosis (2006)

Results in multiple sclerosis patients were similar to those of a previous study in amyotrophic lateral sclerosis, demonstrating that DM/Q may be beneficial in treating potentially disabling pseudobulbar affect in a variety of neurological disorders.
Synthesis, Structure, and Thermal Properties of Soluble Hydrazinium Germanium(IV) and Tin(IV) Selenide Salts (2005)

The crystal structures of two hydrazinium-based germanium(IV) and tin(IV) selenide salts are determined. (N(2)H(5))(4)Ge(2)Se(6) (1) [I4(1)cd, a = 12.708(1) Angstroms, c = 21.955(2) Angstroms, Z = 8] and (N(2)H(4))(3)(N(2)H(5))(4)Sn(2)Se(6) (2) [P, a = 6.6475(6) Angstroms, b = 9.5474(9) Angstroms, c = 9.8830(10) Angstroms, alpha = 94.110(2) degrees, beta = 99.429(2) degrees, gamma = 104.141(2) degrees, Z = 1] each consist of anionic dimers of edge-sharing metal selenide tetrahedra, M(2)Se(6)(4-) (M = Ge or Sn), separated by hydrazinium cations and, for 2, additional neutral hydrazine molecules. Substantial hydrogen bonding exists among the hydrazine/hydrazinium molecules as well as between the hydrazinium cations and the selenide anions. Whereas the previously reported tin(IV) sulfide system, (N(2)H(5))(4)Sn(2)S(6), decomposes cleanly to microcrystalline SnS(2) when heated to 200 degrees C in an inert atmosphere, higher temperatures (>300 degrees C) are required to dissociate selenium from 1 and 2 for the analogous preparations of single-phase metal selenides. The metal chalcogenide salts are highly soluble in hydrazine, as well as in a variety of amines and DMSO, highlighting the potential usefulness of these compounds as precursors for the solution deposition of the corresponding metal chalcogenide films.
MR Vascular Fingerprinting in Stroke and Brain Tumors Models (2016)

In this study, we evaluated an MRI fingerprinting approach (MRvF) designed to provide high-resolution parametric maps of the microvascular architecture (i.e., blood volume fraction, vessel diameter) and function (blood oxygenation) simultaneously. The method was tested in rats (n = 115), divided in 3 models: brain tumors (9 L, C6, F98), permanent stroke, and a control group of healthy animals. We showed that fingerprinting can robustly distinguish between healthy and pathological brain tissues with different behaviors in tumor and stroke models. In particular, fingerprinting revealed that C6 and F98 glioma models have similar signatures while 9 L present a distinct evolution. We also showed that it is possible to improve the results of MRvF and obtain supplemental information by changing the numerical representation of the vascular network. Finally, good agreement was found between MRvF and conventional MR approaches in healthy tissues and in the C6, F98, and permanent stroke models. For the 9 L glioma model, fingerprinting showed blood oxygenation measurements that contradict results obtained with a quantitative BOLD approach. In conclusion, MR vascular fingerprinting seems to be an efficient technique to study microvascular properties in vivo. Multiple technical improvements are feasible and might improve diagnosis and management of brain diseases.
The mitochondrial uncoupler 2,4‐dinitrophenol attenuates tissue damage and improves mitochondrial homeostasis following transient focal cerebral ischemia (2005)

Ischemic stroke is caused by acute neuronal degeneration provoked by interruption of cerebral blood flow. Although the mechanisms contributing to ischemic neuronal degeneration are myriad, mitochondrial dysfunction is now recognized as a pivotal event that can lead to either necrotic or apoptotic neuronal death. Lack of suitable 'upstream' targets to prevent loss of mitochondrial homeostasis has, so far, restricted the development of mechanistically based interventions to promote neuronal survival. Here, we show that the uncoupling agent 2,4 dinitrophenol (DNP) reduces infarct volume approximately 40% in a model of focal ischemia-reperfusion injury in the rat brain. The mechanism of protection involves an early decrease in mitochondrial reactive oxygen species formation and calcium uptake leading to improved mitochondrial function and a reduction in the release of cytochrome c into the cytoplasm. The observed effects of DNP were not associated with enhanced cerebral perfusion. These findings indicate that compounds with uncoupling properties may confer neuroprotection through a mechanism involving stabilization of mitochondrial function.
Hybrid Nearest Level and open loop control of modular multilevel converters (2014)

In this paper a Nearest Level Control with open loop approach for modular multilevel converter (MMC) is proposed. By using open loop approach it is possible to suppress circulating currents without using feedback controllers. Moreover, with this method, both N+1 and 2N+1 levels (N=number of sub-modules) can be obtained at the output voltage. In addition, the voltage quality is improved and the total harmonic distortion is reduced at higher and lower modulation indices by increasing the number of levels up to 2N+1. Simulation results of 3-phase MMC are presented for both 2N+1 and N+1 levels together with the description of proposed Nearest Level Control scheme.

The content of free and bound inositol in human and cow's milk. (1975)

The gaschromatographic method was used for the quantitative analyses of inositol in milk. The content of inositol in human and cow's milk at the different lactation periods was determined. The content of total myoinositol in human milk was 32.7 plus or minus 15.2 mg/100 ml in colostrum, 17.8 plus or minus 1.9 mg/100 ml in transitional milk, and 14.9 plus or minus 3.1 mg/100 ml in mature milk. In cow's milk, it was 10.6 plus or minus 1.0, 7.0 plus or minus 1.1, and 4.1 plus or minus 1.0 mg/100 ml, respectively. These values were very similar to those obtained by the microbiological method. The presence of lipid-bound myoinositol in both kinds of milk was confirmed and the content was 0.22 plus or minus 0.09 mg/100 ml in human milk and 0.36 plus or minus 0.10 mg/100 ml in cow's milk. A small amount of scylloinositol was found in both human and cow's milk, while dextroinositol was not found in either.
Time delay compensation of digital control for DC switchmode power supplies using prediction techniques (2000)

One of the major disadvantages of digital control is the limited control loop bandwidth due to the inherent time delay introduced by the zero-order-hold effect and the computational time delay. To alleviate this problem, two practical and straightforward predictive schemes based on linear extrapolation are proposed. With the proposed schemes, the computational time delay of the control loop is compensated and the control loop bandwidth is increased. It is shown that, using the proposed techniques, the control loop bandwidth can be increased up to two times that of the conventional digital control loop. Also, the computational overhead needed to implement these techniques is kept to the minimum. A lab prototype system of a 1 kV full bridge DC power supply was set up for the proof of concept. The prototype system operated at 10 kHz and was controlled by a TI TMS320F240 DSP (20-MHz 16-bit fixed-point). Simulation and experimental results prove the validity of the proposed techniques.
A dynamic queue MAC protocol for random access channels with multipacket reception (2002)

A dynamic medium access control (MAC) protocol for a finite-user slotted channel with multipacket reception (MPR) capability is proposed. By adaptively changing the size of the contention class (defined as a subset of users who can access the channel at the same time) according to the traffic load and the channel MPR capability, the proposed dynamic queue protocol provides superior channel efficiency at high traffic load and minimum delay at low traffic load. It is shown that considerable throughput gain over purely random access schemes such as slotted ALOHA at heavy traffic load and significant delay improvement over scheduled multiaccess strategies such as TDMA at light traffic load are achieved by the proposed protocol.

BRCA1 expression levels predict distant metastasis of sporadic breast cancers (1999)

The role of BRCA1 in progression of sporadic breast cancers has to date been equivocal, although preliminary studies on small numbers of samples have suggested an association between expression levels of this gene and acquisition of an invasive phenotype. We have further reasoned that loss of oestrogen receptor positivity may have a detrimental effect on BRCA1 expression. In order to test this hypothesis and extend earlier investigations we have applied a sensitive RT-PCR procedure to determine the associations between BRCA1 expression and a variety of clinical parameters in a sample cohort derived from sporadic breast tumour specimens. We have established that BRCA1 and ER mRNA expression are closely associated (p0.013), indicating a possible functional relationship between these 2 genes. We have further identified an association between low levels of BRCA1 expression and acquisition of distant metastasis in sporadic disease (p0.019). In light of our findings, we suggest that suppression of BRCA1 has a role to play in progression of a significant fraction of sporadic breast cancers and may additionally prove to be a useful, novel, prognostic marker for this disease type.
Silica Scale Control (1998)

Abstract Silica is becoming the critical limiting factor in the reuse of water. Silica deposit is caused as a result of its polymerization, coprecipitation with other minerals, precipitation with other multivalent ions, and biological activity in the water. Several of these processes may take place concurrently, making it difficult to predict equilibrium solubility. The solubility of amorphous silica is also dependent on many other factors such as, pH, temperature, particle size, particle hydration, and the presence of other ions, such as iron, aluminum, etc.. A hard silica scale is formed when calcium carbonate or other mineral precipitate provides a crystalline matrix in which silica can be entrapped.
PROPERTIES OF THE OLFACTORY EFFERENT SYSTEM (1960)

SUMMARY Appropriately timed afferent stimulation of one olfactory bulb can depress afferent induced activity in the opposite bulb, the depression being mediated by the true commissural component of the anterior commissure which is part of the olfactory efferent system. Bulbar retrograde responses evoked by lateral olfactory tract stimulation are depressed by continuous high frequency stimulation of the anterior commissure, and this is considered to be further evidence for a depressive action of the efferent system in the olfactory bulb. Stimulation of the efferent system evokes monophasic negative waves in the bulb which, on continuous stimulation, summate to give a sustained negativity. The appearance of this negative shift is correlated with the onset of the depressive influence. Lateral olfactory tract stimulation evokes polyphasic, dominantly positive, waves in the bulb which do not summate but rapidly fatigue on repetitive stimulation at high frequencies.
Molecularly imprinted supermacroporous cryogels for cytochrome <i>c</i> recognition (2011)

Molecular imprinting is an attractive biomimetic approach that creates specific recognition sites for the shape and functional group arrangement to template molecules. The purpose of this study is to prepare cytochrome c-imprinted poly(hydroxyethyl methacrylate) (PHEMA)-based supermacroporous cryogel which can be used for the separation of cytochrome c from protein mixtures. N-Methacryloyl-(L)-histidinemethylester (MAH) was used as the metal-coordinating monomer. In the first step, Cu(2+) was complexed with MAH, and the cytochrome c imprinted PHEMA (MIP) cryogel was prepared by free radical cryopolymerization initiated by N,N,N',N'-tetramethylene diamine at -12°C. After polymerization is completed, the template cytochrome c molecules were removed from the MIP cryogel using 0.5 M NaCl solution. The maximum cytochrome c binding amount was 126 mg/g polymer. Selective binding studies were performed in the presence of lysozyme and bovine serum albumin. The relative selectivity coefficients of MIP cryogel for cytochrome c/lysozyme and cytochrome c/bovine serum albumin were 1.7 and 5.2 times greater than those of the non-imprinted PHEMA cryogel, respectively. The selectivity of MIP cryogel for cytochrome c was also confirmed with fast protein liquid chromatography. The MIP cryogel could be used many times with no remarkable decrease in cytochrome c binding capacity.

Conversion of the conductivity mode in silicon by oxygen ion implantation and its application in a novel dielectric isolation technique (1982)

Implanted oxygen ions have been shown to form donor states and to change the conductivity mode in large regions of p-type single-crystal silicon after a 2-h 450 °C anneal. These donor states are annihilated by a brief high-temperature anneal. With a conventional oxide mask, this phenomenon has been used for the selective formation of low carrier concentration p-type regions dielectrically isolated from a p-type substrate by the full isolation by porous oxidized silicon technique.
Estrogen therapy and liver function—metabolic effects of oral and parenteral administration (1989)

Abstract Oral estrogen therapy for prostatic cancer is clinically effective but also accompanied by severe cardiovascular side effects. Hypertension, venous thromboembolism, and other cardiovascular disorders are associated with alterations in liver metabolism. The impact of exogenous estrogens on the liver is dependent on the route of administration and the type and dose of estrogen. Oral administration of synthetic estrogens has profound effects on liver‐derived plasma proteins, coagulation factors, lipoproteins, and triglycerides, whereas parenteral administration of native estradiol has very little influence on these aspects of liver function.
