Use of simple thermal annealing processes to prepare free-standing platinum rods (2010)

Large-area free-standing Pt rods have been prepared successfully by simply annealing in air platinum films deposited on a sapphire substrate. This paper describes the first examples of the growth of these Pt rods. The Pt rod density is about 2 × 106 cm−2 and the longest Pt rod grown at an angle on sapphire was over a hundred micrometres long. From the ample results of SEM images coupled with the kinetics data, coarsened Pt particles obey the classical ripening process for the first short annealing time, but then followed a vapour–solid growth mode, leading to the formation of Pt rods during the later stages of annealing. Electrical measurements indicate that Pt rods had a resistivity of 10 μΩ cm as well as that of bulk platinum. The electron field emission of Pt rods can be turned on at 5 V μm−1, achieving a maximum current density of 4 mA cm−2 at an applied field of 33 V μm−1. As far as we know, this is the first investigation of the electron field emission properties of Pt rods. Through use of simple thermal annealing processes to prepare free-standing Pt rods, it is promising for future nanoscale device fabrication.
Goose Neck Snare for LV Lead Placement in Difficult Venous Anatomy (2009)

Venous anatomy frequently impairs placement of the left ventricular (LV) lead. In some cases, the wire will not advance into the vein and in others wire position is lost as the lead is advanced. This article describes how a commonly available goose neck snare is used to gain access to the distal end of the wire as it re-enters the coronary sinus retrograde via collaterals through an adjacent vein. The snare is advanced into the coronary sinus through the same catheter as the wire. The snare opens perpendicular to the long axis of the coronary sinus due to which the wire must pass through the open loop, provided the diameter of the snare is approximately the same as the coronary sinus. Thus no time-consuming manipulation of the snare is required. With access to both ends of the wire the vein is approached either retrograde (over the distal end) or antegrade (over the proximal end) while the other end of the wire is secured by the operator. Gaining control of both ends of the wire with a snare is another example of adapting interventional techniques for the device implantation. Unlike venoplasty, the snare does not evoke credentialing concerns and can be easily implemented by most implanting physicians.
Microscopical Detection Of Fiber-Finish Interaction Sites (1977)

In the chemical finishing of textile products, final location of the chemical agent is affected by several factors. Finish location can be critical to production of a desired effect, especially when more than one finish is used on a fabric blended of different fibers. To predetermine location sites, it is first necessary to be able to detect areas of chemical interaction and to determine under what conditions a given location is attained. Microscopical methods show the presence of chemical finishing agents in various sites of the morphological structure of a fabric. Tetramethylol 2,4-diamino-6(3,3,3-tribromopropyl)triazine (TM-DABT) is an effective, durable flame retardant for all-cotton fabrics. Solubility studies of cross sections from TM-DABT-finished cotton fibers indicated that the chemical had penetrated the fiber and insolubilized it to the cellulose solvent cupriethylenediamine hydroxide (cuene).
Naloxone effect on FSH response to LRH in early puerperium (1984)

There is increasing evidence to suggest that pituitary responsiveness to LRH stimulus has been abolished in the immediate puerperium in women (Canales et al. 1974, Keye & Jaffe 1976, Messinis et al. 1983). The factors which control this are presently unclear. Recently, endogenous opiates have been considered to modulate episodic LH secretion through an inhibition of LRH in menstruating women (Ropert et al. 1981). It has also been suggested that in hyperprolactinaemia patients with a pituitary microadenoma an increased inhibition of LH secretion by endogenous opiates occurs (Quigley et al. 1980). The present preliminary study was designed to examine whether endogenous opioids are involved in the control of pituitary responsiveness to LRH postpartum. Two normal puerperal women 21 and 22 years old were studied on day 1 postpartum. They had uneventful pregnancies and normal vaginal deliveries. Informed consent was obtained from both women. The experiments were initiated

Neoplasms of the Notochord. Report of a Case of Basilar Chordoma with Nasal and Bilateral Orbital Involvement (1957)

The name Chordoma, proposed originally by Ribbert, is given to those neoplasms which develop from vestiges of the fetal notochord. The notochord or chorda dorsalis is a column of cells formed in all chordates in the central axis of the individual, ventrally from the neural tube and of mesodermal origin. The chordal cells contain large vacuoles, filled with mucin. These physalipherous cells provide elastic tension by means of their turgor, and thus enable the chorda to carry out its supporting function (protoplasmatic tension system). In lower animals this supporting function is a permanent one. In the embryologic development of the vertebrates the notochord is found as a transitory organ only. Its supporting function is taken over by the vertebrae, developing around the chorda. In some places usually some vestiges of chordal tissue remain; it is from these vestiges, that chordomas may develop.

Isolation of Mycoplasma hominis from genital ulcerations of patients in Eastern and Southern Africa. (1984)

In three separate surveys involving 413 patients in Mbabane (Swaziland), Nairobi (Kenya), and Carletonville (South Africa), Mycoplasma hominis was isolated from the base of ulcers in 41 (16%) of 251 men with genital ulcer disease. Antibodies to M. hominis were detected by indirect hemagglutination in 89 (51%) of 176 such patients. Of these male patients, 15% and 6% had indirect hemagglutinating antibodies at titers of greater than or equal to 160 and greater than or equal to 640, respectively. The rate of isolation of M. hominis and the results of serologic tests for antibodies to this organism were the same whether or not a cause of genital ulcer disease was identified.
Modulation of Antigen-Presenting Capacity of Human Monocytes by HIV-1 gp120 Molecule Fragments (1994)

The two fragments of HIV-1 gp120 molecule were synthesized to study their interaction with human monocytes. Previous observations indicated that recombinant gp120 fragment (aa residues 410-511) encompassing CD4 binding region (rp120cd) induced tumour necrosis factor alpha (TNF) production in monocytes, while a similar fragment (rp120) not containing the CD4 binding sequence (aa 446-511) was inactive. This paper shows that rp120cd depressed monocyte ability to present antigen (PPD) to autologous T lymphocytes while rp120 was noninhibitory. The rp120cd interacted with monocytes but not T lymphocytes. Anti-TNF receptor type A antibody (utr-1) prevented the depression of antigen presentation caused by rp120cd, which suggested a role for TNF and its receptor. The depression of antigen presentation was seen only when monocytes were treated with rp120cd before, but not after, pulse with antigen. Parallel changes were observed in PPD-induced IL-6 production. Thus, induction of TNF by gp120 may be associated with impairment of antigen-presenting capacity of monocytes seen in AIDS patients.
Measurement of the birefringence induced in liquids by ultrasonic waves : application to the study of the isotropic phase of PAA near the transition point (1981)

A technique has been developed for ultrasound-induced birefringence experiments. Measurements made in the isotropic phase of PAA (p-azoxyanisole) show that it is possible to obtain reliable results quickly and in a very simple way through straightforward improvements of the traditional technique. In addition to the induced birefringence measurements our technique also provides measurements of the absorption coefficient of the ultrasonic wave. The cell has a low sample volume and is particularly suited to studies on rare liquids and/or highly attenuating liquids. The results on PAA show that the quantity Δn/√P, where Δn is the induced birefringence and P the acoustic intensity, diverges according to a power law. As one approaches Tc the system crosses over from the ωτ ⪡ 1 regime to the ωτ ∼ 1 regime. The results are interpreted on the basis of the de Gennes model. The orientation relaxation time is deduced from these measurements.
Performance Variations of Leading-Edge Tubercles for Distinct Airfoil Profiles (2011)

An experimental investigation has been undertaken to determine the influence of sinusoidal leading-edge protrusions on the performance of two NACA airfoils with different aerodynamic characteristics. Force measurements on full-span airfoils with various combinations of tubercle amplitude and wavelength reveal that when compared to the unmodified equivalent, tubercles are more beneficial for the NACA 65-021 airfoil than the NACA 0021 airfoil. It was also found that for both airfoil profiles, reducing the tubercle amplitude leads to a higher maximum lift coefficient and larger stall angle. In the poststall regime, however, the performance with largeramplitude tubercles is more favorable. Reducing the wavelength leads to improvements in all aspects of lift performance, including maximum lift coefficient, stall angle, and poststall characteristics. Nevertheless, there is a certain point at which further reduction in wavelength has a negative impact on performance. The results also suggest that tubercles act in a manner similar to conventional vortex generators.
Locusts and Grasshoppers: Future Foods? (2014)

Consuming locusts and grasshoppers as food is not a new concept, because some people have been doing it for a long time and there are many references in the religious literature to support this. About 80 locust and grasshopper species are consumed worldwide, and the large majority of grasshopper species are edible. From the nutritional point of view they are an excellent source of proteins, lipids and other minor components like vitamins and minerals. They are an excellent source of amino acids and their lipids contain a large majority of unsaturated fatty acids. Environmentalists have supported human consumption of grasshoppers owing to the facts that they usually appear as pests. Using them as food could help reduce their population and result in limited application of harmful pesticides. Their production usually generates lesser amount of greenhouse gases & ammonia; a lower amount of water is required for their production in comparison to conventional proteins sources. Some species of grasshoppers usually feed on dead organic matter, this reduces the environmental load. In the developing world, catching of grasshoppers and selling them for human consumption has played a key role in improving the livelihood of women and underprivileged children. Eating grasshopper and locust is not a very common practice in temperate areas. However it is a very common practice in the tropical areas of world because of the higher density, bigger size of the insect and yearlong availability in such areas. To encourage their consumption in temperate areas, it is now necessary to perform accurate research regarding food safety (minor components, toxicity, allergens,…) but also to develop value added products to make it easier for people to adapt with entomophagy. Furthermore we have to develop methods for commercial production and organize awareness campaigns to explain about the nutritional and other benefits related to locust & grasshopper consumption as food to people.
Dispersion of the Refractive Index near the Fundamental Absorption Edge in PbS (1963)

A peak in the wavelength dependence of the index of refraction resulting from the increase in the extinction coefficient at the absorption edge has been observed in PbS. The results were obtained by analysis of the reflection spectra of $n$-type single crystal film and bulk samples. At 300\ifmmode^\circ\else\textdegree\fi{}K the refractive index at the peak is approximately 7% larger than the square root of the optical dielectric constant. The peak moves with the absorption edge with decreasing temperature. The optical dielectric constant at room temperature was found to be 16.8.
Livesolving: Enabling Collaborative Problem Solvers to Perform at Full Capacity (2015)

Collaborative problem solving is a key methodology for tackling complex and/or contentious problems. The methodology is supported by computer and communication systems that bring human solvers together with computational agents and provide clear protocols for exploring and rating alternative solution approaches. However, these systems can be challenging to use due not only to the complexity of the problems being solved but the variety of abstractions involved in managing the solution process, e.g., problem representations, collaborations, and strategies. This paper offers new ideas to help the human users of such systems to learn and work more effectively. It also suggests how problem solving may sometimes be carried out in performance contexts similar to those of livecoding improvisational music. Most important here is the identification of seven forms of liveness in problem solving that may heighten a solving team’s sense of engagement. Common themes among them are increasing solvers’ awareness and minimizing latency between solver intentions and system responses. One of the seven livesolving forms involves solvers in tracing paths within problem-space graphs. This and the other six forms derive from experience with a system called CoSolve, developed at the University of Washington.

Geographical variations in carbon and nitrogen stable isotope ratios in squid (2000)

The magnitude of geographical variations of stable isotope ratios of carbon and nitrogen was examined in ten squid species captured in seven areas of the world's oceans. The average of all 139 squid was −17.4±1.4‰ for δ 13 C and 11.6±1.6‰ for δ 15 N. The δ 13 C of squid showed a clear-cut negative correlation with the latitude of the sampling locations, reflecting the well-known latitudinal characteristics of phytoplankton δ 13 C, while squid δ, 15 N did not correlate with the latitude significantly. The δ 15 N reflected the regional characteristics of nitrogen metabolism such as denitrification and N 2 fixation, and it was conspicuous in the intraspecific variation in Sthenoteuthis oualaniensis ranging from 10.0±1.5‰ off Japan to 16.3±0.6‰ off Peru in the Pacific Ocean. Significant isotopic variations were also found in the local area among the five species off Japan in the Pacific Ocean and among the three species in the Japan Sea. Attention must be paid to the isotopic variations of primary producers as well as those of squid in examining the trophic positions of squid.
NAT2 slow acetylation and GSTM1 null genotypes may increase postmenopausal breast cancer risk in long-term smoking women (2003)

N-acetyltransferase (NAT) 1 and 2 and glutathione S-transferase (GST) M1 and T1 are phase II enzymes that are important for activation and detoxification of carcinogenic heterocyclic and aromatic amines, as present in cigarette smoke. We studied whether genetic polymorphisms in these genes modifies the relationship between smoking and breast cancer. A nested case-control study was conducted among participants in a Dutch prospective cohort. Breast cancer cases (n=229) and controls (n=264) were frequency-matched on age, menopausal status and residence. Compared to never smoking, smoking 20 cigarettes or more per day increased breast cancer risk statistically significant only in postmenopausal women [odds ratio (OR)=2.17; 95% confidence interval (CI) 1.04-4.51]. Neither NAT1 slow genotype, or GSTT1 null genotype, alone or in combination with smoking, affected breast cancer risk. However, compared to individuals with rapid NAT2 genotype, women with the very slow acetylator genotype (NAT2*5), who smoked for 20 years showed an increased breast cancer risk (OR=2.29; 95% CI 1.06-4.95). Similarly, the presence of GSTM1 null genotype combined with high levels of cigarette smoking (OR=3.00; 95% CI 1.46-6.15) or long duration (OR=2.53; 95% CI 1.24-5.16), increased rates of breast cancer. The combined effect of GSTM1 null genotype and smoking high doses was most pronounced in postmenopausal women (OR=6.78; 95% CI 2.31-19.89). In conclusion, our results provide support for the view that women who smoke and who have a genetically determined reduced inactivation of carcinogens (GSTM1 null genotype or slow NAT2 genotype (especially very slow NAT2 genotype)) are at increased risk of breast cancer.
Ab Initio Studies of Coke Formation on Ni Catalysts During Methane Reforming (2006)

The atomic-scale processes that control the formation of carbon deposits on Ni catalysts in reforming applications are poorly understood. Ab initio Density Functional Theory calculations have been used to examine several key elementary steps in the complex network of chemical reactions that precedes carbon formation on practical catalysts. Attention has been focused on the disproportionation of CO. A comparative study of this reaction on flat and stepped crystal planes of Ni has provided the first direct evidence that surface carbon formation is driven by elementary reactions occurring at defect sites on Ni catalysts. The adsorption and diffusion of atomic H on several flat and stepped Ni surfaces has also been characterized experimentally.

Increased Expression of the E3-Ubiquitin Ligase Receptor Subunit βTRCP1 Relates to Constitutive Nuclear Factor-κB Activation and Chemoresistance in Pancreatic Carcinoma Cells (2005)

The permanent activation of the transcription factor nuclear factor-kappaB (NF-kappaB) in pancreatic cancer cells is associated with a profound resistance towards chemotherapy. In the present study, we show that chemoresistant pancreatic cancer cell lines exhibiting constitutive NF-kappaB activity (i.e., PancTu-1, BxPc3, and Capan-1) express significantly elevated levels of the E3-ubiquitin ligase receptor subunit betaTRCP1, compared with pancreatic carcinoma cell lines lacking constitutive NF-kappaB activity and chemoresistance (i.e., PT45-P1 and T3M4). If transfected with betaTRCP1, PT45-P1 cells exhibit an elevated NF-kappaB activity and become less sensitive towards anticancer drug treatment (i.e., etoposide). Conversely, blockade of betaTRCP1 expression in PancTu-1 cells by transfection with a vector-expressed small interfering RNA reduces NF-kappaB activation and chemoresistance. In PancTu-1 cells, betaTRCP1 expression is inhibited, at least in part, by the interleukin-1 (IL-1) receptor(I) antagonist, whereas stimulation of PT45-P1 cells with IL-1beta resulted in an increased expression of betaTRCP1, and transfection of this cell line with betaTRCP1 induced IL-1beta secretion in a NF-kappaB-dependent fashion. Thus, via its close and mutual link to IL-1beta secretion, betaTRCP1 expression might substantially contribute to the persistent, IL-1beta-dependent activation of NF-kappaB in pancreatic carcinoma cells. In support of this, betaTRCP1 expression is detectable at considerable levels in a great number of pancreatic ductal adenocarcinoma specimens, along with an intense staining for activated NF-kappaB. Altogether, our findings of the elevated betaTRCP1 expression in pancreatic carcinoma cells pinpoint to another important mediator of constitutive NF-kappaB activation and thereby of chemoresistance.
