Fever Management Practices of Neuroscience Nurses (2007)

Neuroscience patients with fever may have worse outcomes than those who are afebrile. However, neuroscience nurses who encounter this common problem face a translational gap between patient-outcomes research and bedside practice because there is no current evidence-based standard of care for fever management of the neurologically vulnerable patient. The aim of this study was to determine if there are trends in national practices for fever and hyperthermia management of the neurologically vulnerable patient. A 15-item mailed questionnaire was used to determine national and regional trends in fever and hyperthermia management and decision making by neuroscience nurses. Members of the American Association of Neuroscience Nurses were surveyed (N = 1,225) and returned 328 usable surveys. Fewer than 20% of respondents reported having an explicit fever management protocol in place for neurologic patients, and 12.5% reported having a nonspecific patient protocol available for fever management. Several clear and consistent patterns in interventions for fever and hyperthermia management were seen nationally, including acetaminophen administration at a dose of 650 mg every 4 hours, ice packs, water cooling blankets, and tepid bathing. However, regional differences were seen in intervention choices and initial temperature to treat.
Tecnología y autogestión en cooperativas de trabajo (2016)

¿Una forma de organización social diferente requiere de la implementación de tecnologías productivas y de organización diferentes? Partimos de esta pregunta para analizar el rol asignado a la tecnología en cooperativas de trabajo autogestionadas ubicadas en la provincia de Buenos Aires y Santa Fe. Nuestro análisis permite concluir que estas cooperativas, en tanto organizaciones sociales y productivas diferentes a aquellas que tienen al capital como eje organizador, a través de determinados mecanismos específicos -igualdad entre los miembros, posibilidad de tomar decisiones por parte de todos los trabajadores, orientaciones hacia la justicia, dispersión del poder-, posibilitan otras formas de interactuar e implementar tecnologías. Por otro lado, observamos que en aquellas cooperativas en las cuales los trabajadores asumían un fuerte compromiso político y cuestionamiento del orden social vigente, también había una preocupación por implementar modos de trabajo que resguarden la salud física y mental de los trabajadores.
Nanotechnology in agri-food production: an overview (2014)

Nanotechnology is one of the most important tools in modern agriculture, and agri-food nanotechnology is anticipated to become a driving economic force in the near future. Agri-food themes focus on sustainability and protection of agriculturally produced foods, including crops for human consumption and animal feeding. Nanotechnology provides new agrochemical agents and new delivery mechanisms to improve crop productivity, and it promises to reduce pesticide use. Nanotechnology can boost agricultural production, and its applications include: 1) nanoformulations of agrochemicals for applying pesticides and fertilizers for crop improvement; 2) the application of nanosensors/nanobiosensors in crop protection for the identification of diseases and residues of agrochemicals; 3) nanodevices for the genetic manipulation of plants; 4) plant disease diagnostics; 5) animal health, animal breeding, poultry production; and 6) postharvest management. Precision farming techniques could be used to further improve crop yields but not damage soil and water, reduce nitrogen loss due to leaching and emissions, as well as enhance nutrients long-term incorporation by soil microorganisms. Nanotechnology uses include nanoparticle-mediated gene or DNA transfer in plants for the development of insect-resistant varieties, food processing and storage, nanofeed additives, and increased product shelf life. Nanotechnology promises to accelerate the development of biomass-to-fuels production technologies. Experts feel that the potential benefits of nanotechnology for agriculture, food, fisheries, and aquaculture need to be balanced against concerns for the soil, water, and environment and the occupational health of workers. Raising awareness of nanotechnology in the agri-food sector, including feed and food ingredients, intelligent packaging and quick-detection systems, is one of the keys to influencing consumer acceptance. On the basis of only a handful of toxicological studies, concerns have arisen regarding the safety of nanomaterials, and researchers and companies will need to prove that these nanotechnologies do not have more of a negative impact on the environment.
Guidance for the treatment of neovascular age-related macular degeneration (2007)

Neovascular age-related macular degeneration is becoming an increasing socio-medical problem as the proportion of the aged population is continuously increasing. However, new insights in the pathogenesis of the disease offer the opportunity to develop targeted therapies that attack the disease process more successfully than ever. This review article will focus on summarizing the actual options in the management of neovascular age-related macular degeneration and provide a short overview about recent therapeutic options in clinical and preclinical evaluation. The recent development of anti-VEGF substances for use in clinical routine has markedly improved the prognosis of patients with neovascular AMD. Intravitreal treatment with substances targeting all isotypes of vascular endothelial growth factor (VEGF), for the first time in the history of AMD treatments, results in a significant increase in visual acuity in patients with neovascular AMD. Overall, antiangiogenic approaches provide vision maintenance in over 90% and substantial improvement in 25-40% of patients. The combination with occlusive therapies like photodynamic therapy (PDT) potentially offers a reduction of re-treatment frequency and long-term maintenance of the treatment benefit. Further developments interacting with various steps in the angiogenic cascade are under clinical or preclinical evaluation and may soon become available. Nevertheless, the growing number of novel therapeutic options will have to provide proof of concept in randomized controlled clinical trials, a major challenge in view of the rapidly evolving field. For those therapies, which are already in clinical use, reasonable diagnostic tools for follow-up need to be developed, as the burden of continuous clinical monitoring of all patients and all indications is significant for patients and doctors. Ultimately, economic issues will be the limiting factor for the clinical availability of different treatment options.

Epidemiology and Adverse Cardiovascular Risk Profile of Diagnosed Polycystic Ovary Syndrome (2006)

Within a large, community-based population receiving health care, diagnosed PCOS was highly prevalent and associated with a much higher frequency of cardiovascular risk factors that varied by race/ethnicity. Our prevalence estimates likely underestimate the true prevalence of PCOS. Further studies are needed to explore racial/ethnic differences and the extent to which PCOS contributes to future cardiovascular risk.
Drag Reduction by Applying Speedstrips on Rowing Oars (2016)

The objective of this study was to determine the advantage of the application of speedstrips to rowing oars for a lightweight single sculler. The research method comprehended three steps: (1) the analysis of the rowing oar movement, (2) the determination of the change in drag and (3) the composition of a rowing model to establish the advantage that could be achieved. The parameters needed for the model: boat velocity, oar angle velocity and power delivered by the rower, were recorded on a real single sculler. The change in drag due to speedstrips on cylinders was determined by performing wind tunnel experiments. The rowing model (Matlab) simulates a race by using real stroke data of a world-class rower as input, while calculating the drag with the coefficients determined by the wind tunnel experiments. The output of the model is the final advantage by the application of speedstrips to rowing oars. Speedstrips induce a 0.1% advantage over a 2000 m race under calm wind conditions. The advantage increases up to .4% with a headwind velocity of 5 m s-1. For bigger boats, the advantage could be even more significant.
Nuclear morphometry in solar keratosis. (1998)

Karyometry of nuclei from skin biopsies allows objective assessment of the progression of solar keratotic lesions. Similarity of feature values in nuclei from solar keratotic lesions to those in malignant lesions was noted. The progression curve derived in this study could serve to measure the efficacy of chemopreventive or therapeutic intervention.
Chlamydia trachomatis infections in asymptomatic women. Results of a study employing different staining techniques. (1989)

A total of 300 cervical smears randomly collected from asymptomatic women in a mass-screening program for the detection of cervical carcinoma was investigated for Chlamydia trachomatis infection by the use of Papanicolaou and immunofluorescence staining. Features of chlamydial infection detected in 18 cases by Papanicolaou-stained smears were confirmed in 11 cases with immunofluorescence; not a single case that was negative in the Papanicolaou-stained smears was positive by immunofluorescence. The presence of Chlamydia in the Papanicolaou-stained smears in ten cases, including two cases that were negative by immunofluorescence, was also proven by either immunoperoxidase staining or in situ hybridization. On the other hand, either immunoperoxidase or in situ hybridization gave false-negative results in two of the ten cases. Therefore, the combined use of different techniques demonstrated that false-negative results occurred with all techniques, except with Papanicolaou-stained smears, whose sensitivity is apparently the highest.
Cardiovascular Autonomic Functions in Alzheimer's Disease (1994)

We investigated cardiovascular autonomic functions in 23 patients with Alzheimer's disease (AD) and 23 age-matched control subjects. The vagal parasympathetic function was assessed with R-R interval variation (RRIV), and sympathetic function with sympathetic skin response (SSR) and orthostatic cardiovascular reflexes. Compared with controls, the AD patients had significantly depressed RRIV during rest (6.4 +/- 1.3% vs. 7.5 +/- 1.6%, p < 0.02) and deep breathing (12.6 +/- 4.6% vs. 17.0 +/- 5.1%, p < 0.006), but all AD patients had normal SSR. After standing for 3 minutes from supine, the changes of blood pressure and heart rate from baseline in AD patients did not differ from those in controls. The AD patients had a lower systolic blood pressure than controls in both supine (130.7 +/- 17.4 vs. 145.4 +/- 20.7 mmHg, p < 0.02) and standing (129.2 +/- 20.1 vs. 146.6 +/- 21.1 mmHg, p < 0.008) positions, especially in those patients with more severe dementia. We conclude that AD patients have mildly impaired autonomic functions, mainly in vagal parasympathetic functions. The pathogenesis and clinical significance of low blood pressure in AD needs further study.

Analgesic Efficacy of an Ibuprofen‐Codeine Combination (1982)

Subjects who had undergone dental impaction surgery and who had moderate to severe postoperative pain were given, under double-blind, randomized conditions, a single dose of either codeine 60 mg, aspirin 650 mg, ibuprofen 400 mg, aspirin 650 mg + codeine 60 mg, ibuprofen 400 mg + codeine 60 mg, or placebo. A total of 249 subjects were included in the statistical analysis. On a report form, subjects recorded pain intensity, pain relief, and side effects hourly for four hours. They also gave an overall impression at the end of the observation period. Analysis of variance and pairwise contrasts were used to analyze the data. For the sum of pain intensity differences, the total of the hourly pain relief scores, and overall impression, there was a significant analgesic effect for codeine, aspirin, and ibuprofen and no significant interaction when they were used in combination. Ibuprofen alone was statistically superior to aspirin and also achieved higher mean scores than the aspirin-codeine combination. The ibuprofen-codeine combination was the most effective treatment for every analgesic parameter, but it was not statistically superior to ibuprofen alone. The possibility exists that the ibuprofen-codeine combination peaked out the sensitivity of the model. There was no notable difference in the frequency or intensity of side effects among the treatment groups, and no subject had to withdraw due to an adverse effect. This study again confirms the superiority of ibuprofen to aspirin and suggests that ibuprofen is at least as effective as an aspirin-codeine combination. Codeine added a small amount of additional analgesia when used in combination with ibuprofen.
Achieving Mobility for DVB-T by Signal Processing for Doppler Compensation (2002)

Mobile reception of DVB-T signal is significantly affected by the fast-changing transmission channel. As a result, existing equipment that is suited for static reception does not guarantee the necessary quality of service (QoS) for speeds beyond 30 km/h. In order to achieve higher speeds, most of the current solutions propose to use two antennas at the receiver and a more elaborate signal processing for the channel tracking. In this paper, we consider a signal processing technique that specifically addresses the time-varying nature of the channel and allows to reach speeds beyond 100 km/h on a receiver equipped with a single antenna. The proposed scheme performs the cancellation of the interference due to the channel variations. The building blocks of the new algorithm have been optimised in order to reduce the complexity. A combination of both the new signal processing and the use of two antenna at the receiver has also been considered, in order to achieve high speed also for the configurations of the DVB-T which are most affected by mobility. Simulations show that the use of the new signal processing yields a significant improvement in terms of maximum speed that can be reached with an appropriate QoS.

Graphene transistors 2011 (2011)

Graphene is a promising electronic material and numerous experts already see it as the successor of silicon. Many groups are fabricating graphene transistors, and graphene MOSFETs with record cutoff frequencies of 300 GHz have been reported. However, in spite of this progress, the prospects of graphene transistors for future electronics are still not clear. The aim of the present paper is to shed some light on the merits and problems of graphene transistors and to review their current status.
Schottky barriers at metal-finite semiconducting carbon nanotube interfaces (2003)

Electronic properties of metal-finite semiconducting carbon nanotube interfaces are studied as a function of the nanotube length using a self-consistent tight-binding theory. We find that the shape of the potential barrier depends on the long-range tail of the charge transfer, leading to an injection barrier thickness comparable to half of the nanotube length until the nanotube reaches the bulk limit. The conductance of the nanotube junction shows a transition from tunneling to thermally activated transport with increasing nanotube length.
Reliability of Fourier-transform spectral interferometry (2000)

We demonstrate the incidence of several issues detrimental to the reliability of spectral interferometry: frequency calibration, frequency interpolation, spectral resolution and aliasing. Taking these issues into account results in a more accurate retrieved spectral phase.

Noninvasive measurement of gene expression in skeletal muscle (2000)

We have developed a noninvasive detection method for expression of viral-mediated gene transfer. A recombinant adenovirus was constructed by using the gene for arginine kinase (AK), which is the invertebrate correlate to the vertebrate ATP-buffering enzyme, creatine kinase. Gene expression was noninvasively monitored using (31)P-magnetic resonance spectroscopy ((31)P-MRS). The product of the AK enzyme, phosphoarginine (PArg), served as an MRS-visible reporter of AK expression. The recombinant adenovirus coding for arginine kinase (rAdCMVAK) was injected into the right hindlimbs of neonatal mice. Two weeks after injection of rAdCMVAK, a unique (31)P-MRS resonance was observed. It was observable in all rAdCMVAK injected hindlimbs and was not present in the contralateral control or the vehicle injected limb. PArg and phosphocreatine (PCr) concentrations were calculated to be 11.6 +/- 0.90 and 13.6 +/- 1.1 mM respectively in rAdCMVAK injected limbs. AK activity was demonstrated in vivo by monitoring the decreases in PArg and ATP resonances during prolonged ischemia. After 1 h of ischemia intracellular pH was 6.73 +/- 0.06, PCr/ATP was decreased by 77 +/- 8%, whereas PArg/ATP was decreased by 50 +/- 15% of basal levels. PArg and PCr returned to basal levels within 5 min of the restoration of blood flow. AK activity persisted for at least 8 mo after injection, indicating that adenoviral-mediated gene transfer can produce stable expression for long periods of time. Therefore, the cDNA encoding AK provides a useful reporter gene that allows noninvasive and repeated monitoring of gene expression after viral mediated gene transfer to muscle.
THE INCIDENCE OF TOXOPLASMA ANTIBODIES IN MENTAL HOSPITAL PATIENTS (1961)

Summary Of 342 inmates of a mental hospital, 19 possessed complement‐fixing and 60 dye‐test antibodies against Toxoplasma gondii . The incidence of complement‐fixing antibodies was less in the hospital patients than in the general population. This suggests that the risk of post‐natal infection with Toxoplasma was less in the hospital environment than outside. Among 116 children with congenital mental deficiency of unspecified ætiology, there was serological evidence that Toxoplasma was a possible cause in eight, or 7%, but in none was this confirmed by the presence of chorio‐retinitis or cerebral calcification. In the patients studied, toxoplasmosis was at most only a rare cause of congenital mental deficiency.
Final report on LDRD project : biodiesel production from vegetable oils using slit-channel reactors. (2008)

This report documents work done for a late-start LDRD project, which was carried out during the last quarter of FY07. The objective of this project was to experimentally explore the feasibility of converting vegetable (e.g., soybean) oils to biodiesel by employing slit-channel reactors and solid catalysts. We first designed and fabricated several slit-channel reactors with varying channel depths, and employed them to investigate the improved performance of slit-channel reactors over traditional batch reactors using a NaOH liquid catalyst. We then evaluated the effectiveness of several solid catalysts, including CaO, ZnO, MgO, ZrO{sub 2}, calcium gluconate, and heteropolyacid or HPA (Cs{sub 2.5}H{sub 0.5}PW{sub 12}O{sub 40}), for catalyzing the soybean oil-to-biodiesel transesterification reaction. We found that the slit-channel reactor performance improves as channel depth decreases, as expected; and the conversion efficiency of a slit-channel reactor is significantly higher when its channel is very shallow. We further confirmed CaO as having the highest catalytic activity among the solid catalysts tested, and we demonstrated for the first time calcium gluconate as a promising solid catalyst for converting soybean oil to biodiesel, based on our preliminary batch-mode conversion experiments.
The relationship between synovitis and bone changes in early untreated rheumatoid arthritis: A controlled magnetic resonance imaging study (1999)

MCP joint bone edema is present in the majority of patients with RA at presentation, but is seen only occasionally in normal control subjects. The fact that bone edema occurred rarely in the absence of synovitis in patients with RA suggests that bony changes in RA are secondary to synovitis.
Cytologic, histologic and clinical correlations of precancerous and cancerous oral lesions in 57,518 industrial workers of Gujarat, India. (1977)

President Roosevelt is pleased with Henry White's news on the Alaska business. The Canadians have published some ugly articles that might influence English opinion. It will be unfortunate if the Commission is deadlocked but even worse for the Canadians and English. If an agreement cannot be reached, Roosevelt will treat the disputed territory as American and forbid all future negotiations.
Prolonged Hematopoietic Chimerism in Normal Mice Transplanted in utero with Human Hematopoietic Stem Cells (1998)

We have previously reported prolonged hematopoietic chimerism in normal mice transplanted in utero with human fetal hematopoietic stem cells (HSC) by flow cytometry. We now further confirm the human origin of these cells by demonstrating human DNA in the marrow of one such chimeric mouse. We also examined 42 mice born after in utero transplantation with HSC enriched from human adult marrow cells. All live-born mice were treated with recombinant human growth factors. Twelve had human cells in the peripheral blood (range: 01.-2.93%). Thymic samples were positive in 3 cases. The bone marrow of 2 mice contained cells expressing human CD34 antigen. Light scatter characteristics support the presence of multilineage hematochimerism. Human IgM was present in 2 of 4 chimeric sera tested. Thus, normal mice transplanted in utero with human HSC may permit long-term engraftment and differentiation of the human HSC.
A non‐linear algorithm for estimating three‐hourly rain rates over Amazonia from GOES/VISSR observations (1994)

Abstract Recent work has suggested that infrared window brightness temperatures can be regressed in a non‐linear formulation to estimate three‐hourly rain rates. We describe an Infrared Power law Rain rate (IPR) algorithm, which is based on such a formulation. Because it is continuous, IPR preserves the structure present in colder regions of an infrared image. In a test over Amazonia, IPR performed as well as three other infrared rain estimation techniques.
