A Phase I Study of Recombinant Interleukin 2 in Melanoma Patients. Toxicity and Clinical Effects

Toxicity and clinical effects of a new brand of recombinant interleukin 2 (rIL2, Bioleukin™, Biogen, Geneva) were evaluated by a phase I study in 12 patients with stage III melanoma. Escalating doses from 100 μg/m2 to 800 μg/m2 were administered thrice a day with bolus injections given via a peripheral venous catheter for up to a maximum of 7 days. All patients showed malaise, fever and chills and mild gastrointestinal side effects. A modest electrolyte imbalance (hypocalcemia and hypokalemia) was detected in all 12 patients. Renal toxicity as judged by serum creatinine was not observed, and hepatic toxicity was moderate with the possible exception of one patient who had an unclear previous history of liver dysfunction. Mild, transient leukopenia was found in several patients, whereas thrombocytopenia developed in 4 patients; no anemia was observed. Cutaneous rash was seen in half of the patients treated. Fluid retention was minimal, with a weight gain associated to treatment that never exceeded 10% of pretreatment body weight. Electrocardiographic alterations developed in 2 patients in the form of ventricular and supraventricular extrasystoles. In 2 patients given the highest dose of rIL2, a significant reduction in transfer lung factor for carbon monoxide was seen, indicating alterations in pulmonary functions. Other dose-related toxicities were thrombocytopenia and malaise. All side effects disappeared 2-3 days after the end of rIL2 administration. No major responses were seen in association with the 4-8 days of treatment given in this study.
Promotion of oral health by community nurses.

AIM To explore the enablers and barriers perceived by community nurses in the promotion of oral health in an adult community trust directorate. BACKGROUND Oral health care promotion in community care settings is being neglected. England and Wales have witnessed marked improvements in periodontal disease; however, no improvements have been seen in older people. METHOD A qualitative methodology was employed, where eight nurses from Band 5 to 7 were interviewed using a semi-structured approach. The data was analysed thematically. FINDINGS Data analysis was organised into four themes: professional self-concept and the development of knowledge, skills and attitudes necessary in the promotion of oral health; the impact an organisation has on the promotion of oral health and an exploration of the enablers and barriers identified by the community nurses while delivering care; the relationships between the nurse and patient and the potential impact on oral health promotion; the concept of self-regard in relation to the promotion of oral health and its overall impact. A commitment to improving oral health and requests for additional educational input were apparent. Organisational enablers and barriers were identified, alongside the crucial role a positive self-regard for oral health care may play in the promotion of oral health. CONCLUSION Nurses need relevant education, organisational support, adequate resources and support from a multidisciplinary team to deliver optimal oral health promotion.
Yoga – a laborious way to well-being: patients’ experiences of yoga as a treatment for hypertension in primary care

Abstract Objective: The aim of the study was to describe patients’ experience of yoga as a treatment for hypertension, as well as their experience of living with hypertension. Design: Qualitative interview study Method and materials: In 2013–2014, in southern Sweden, patients with hypertension from three health care centres were invited to participate in a randomised controlled trial on yoga for hypertension. After completion of the study, eight women and five men (aged 35–79), who had practiced the yoga intervention, were interviewed about their experiences. We used a semi-structured interview guide according to Kvale. Qualitative analysis was conducted by systematic text condensation inspired by Malterud. Results: Two main themes emerged during the analysis process: Yoga – a laborious way to well-being and hypertension – a silent disease. The positive experiences of doing yoga were described in terms of tranquillity and increased agility. The drawbacks were mainly linked to the time required to perform the exercises. Living with high blood pressure and having to take medication can imply a stigma and cause concerns for future cardiovascular events. Most patients that we interviewed expressed a wish to find alternative ways to treat their high blood pressure. Participating in the yoga study was seen as a good possibility to try such an alternative way. Conclusions: Many patients with hypertension in Swedish primary care seem to be interested in trying alternative treatments to control blood pressure. The patients in our study experienced several benefits from doing yoga, but they also pointed out difficulties in implementing yoga as a regular and permanent lifestyle change.
Identification, cloning, and characterization of the Ima operon, whose gene products are unique to Listeria monocytogenes

The lmaA gene of Listeria monocytogenes encodes a protein capable of inducing delayed-type hypersensitivity reactions in L. monocytogenes-immune mice (S. Göhmann, M. Leimeister-Wachter, E. Schiltz, W. Goebel, and T. Chakraborty, M. Microbiol. 4:1091-1099, 1990). Here we show that it is the last gene of the lma operon, which now comprises four genes, lmaDCBA. Maxicell analysis of peptides encoded by the lma operon identified four polypeptides of 16.7, 16.4, 14.9, and 21 kDa which correspond to the gene products encoded by the lmaD, -C, -B, and -A genes, respectively. Northern blot analysis of the lma operon showed that lmaA is expressed by two transcripts: the longer lmaDCBA transcript of 2,100 nucleotides, which was observed at growth temperatures of 37 and 20 degrees C, and a shorter transcript consisting of lmaBA, which is detected only at low temperatures (20 degrees C). Two promoters, one preceding the lmaD gene and another located upstream of the lmaB gene, were detected. An extended stem-loop structure resembling box elements found in other gram-positive pathogens was also present in the lmaC-lmaB intergenic region. By immunoblot analysis, we found that although LmaA was produced at both temperatures (20 and 37 degrees C), it was secreted into culture supernatants only at 20 degrees C. However, LmaA lacks a bona fide signal peptide sequence and could, like flagellin, be secreted by a type III transport system. DNA hybridization studies indicate that the lma operon is species specific and restricted to pathogenic strains of L. monocytogenes.

This paper presents the evaluation of multiple-input-multiple-output (MIMO) arrays by analyzing the mutual coupling, correlation coefficient, and total active reflection coefficient. The meaning and analysis of the three parameters are demonstrated in this paper. We show the effect of spatial and pattern diversity on MIMO arrays. We also attempt to achieve optimization of the array antenna's allocation for wireless broadband MIMO applications by performance evaluation
An optimization model of under frequency load shedding in interconnected AC/DC power system considering emergency generation control

When a large disturbance resulting in large active power deficiency occurs, emergency automatic generation control (EAGC) and under frequency load shedding (UFLS) are the effective means to maintain frequency stability. In order to coordinate with UFLS, this paper considers the coordinated control of increasing the generators output and emergency power support of HVDC to enhance the system frequency stability in interconnected AC/DC power system. On this basis, an optimization model that concerns both frequency recovery performance and minimum amount of load shedding has been proposed, and the setting of action frequency and load shedding amount of UFLS scheme is designed. A corrected algorithm, named cloud adaptive particle swarm optimization with dimension mutation operator (CAPSO-DMO) is used for the above problem. The control and optimization algorithm is programmed in MATLAB. The simulation result verified the feasibility and effectiveness of the proposed model and method.
Formation and remodeling of the coronary vascular bed in the embryonic avian heart

To study the formation of the coronary vessels in the developing avian heart, we stained developmentally staged quail hearts with the endothelial specific antibody QH‐1. QH‐1 reacted with individual cells in the proepicardial organ in Hamburger and Hamilton stage (HH) 17 embryos only after it had contacted the heart. In HH18–26 hearts, individual QH‐1+ cells accumulated over the surface of the atria and ventricles. The first endothelial vessels appeared in the dorsal atrioventricular groove in HH23 hearts. CD45+ hematopoietic precursors accumulated on the heart surface, demonstrating the close temporal relationship of hematopoiesis with vasculogenesis during heart development. However, CD45 expression preceded association of these cells with the vasculature, suggesting hematopoietic commitment precedes formation of blood islands in the coronary vasculature. Endothelial tubules first appeared on the dorsal and then the ventral aspects of the heart, coalescing into large sinusoids. These sinusoids remodeled into compact muscularized vessels by HH35. Smooth muscle cell markers were first expressed at HH27 and only in association with developing vasculature. We did not observe markers of smooth muscle differentiation in the proepicardium, but it remains uncertain whether cells in the proepicardium are committed to this cell fate. Our data support a strictly vasculogenic mechanism for the formation of the coronary vessels and blood islands. Developmental Dynamics 230:34–43, 2004. © 2004 Wiley‐Liss, Inc.
An Innovative Method for Thermal Characterization of Automotive Electronic Devices Based on CNNs

In this paper, a new approach for the thermal characterization of power electronic devices is introduced. The new method is based on cellular nonlinear networks (CNNs). By using the proposed technique, the thermal impedance of the device can be derived by processing a series of thermal maps, which can be acquired from a single experimental trial. In contrast, the most common technique (the delta drain-source voltage method) used for thermal characterization requires that the device is turned off after each single measure. The approach is validated on a power electronic device used in automotive applications, proving that the CNN-based method has an accuracy comparable with that of the delta drain-source voltage method but is more efficient in terms of time and human resources needed for device characterization.
Identification of the amino acid residues of the amino terminus of vimentin responsible for DNA binding by enzymatic and chemical sequencing and analysis by MALDI-TOF.

The amino acid residues responsible for stable binding of nucleic acids by the intermediate filament (IF) subunit protein vimentin were identified by a combination of enyzmatic and chemical ladder sequencing of photo-cross-linked vimentin-oligodeoxyribonucleotide complexes and analysis by MALDI-TOF mass spectrometry. Three tryptic peptides of vimentin (vim(28)(-)(35), vim(36)(-)(49), and vim(50)(-)(63)) were found to be cross-linked to oligo(dG.BrdU)(12). dG.3'-FITC. From a methodological standpoint, it was necessary to remove the bulk of the bound oligonucleotide by digestion with nuclease P1 to get reproducible spectra for most of the peptides studied. Additionally, removal of the phosphate group of the residually bound dUMP or modification of the amino terminus of the peptide-oligonucleotide complexes with dimethylaminoazobenzene isothiocyanate dramatically improved the quality of the MALDI-TOF spectra obtained, particularly for the vim(28)(-)(35) peptide. A single Tyr residue within each of these peptides (Tyr(29), Tyr(37), and Tyr(52)) was unequivocally demonstrated to be the unique site of cross-linking in each peptide. These three Tyr residues are contained within the two beta-ladder DNA-binding wings proposed for the middle of the vimentin non-alpha-helical head domain. The experimental approach described should be generally applicable to the study of protein-nucleic acid interactions and is currently being employed to characterize the DNA-binding sites of several other IF subunit proteins.
Media Façades beyond interaction

As part of a the research project Digital Urban Living [www.digitalurbanliving. dk], we have taken part in the design of two large-scale installations that employ interactive technologies to facilitate participation and foster social interactions in public, urban settings. We present the two cases, Aarhus by Light and Projected Poetry, and discuss the future trajectory of our work in this field, as well as some of our findings regarding the challenges of designing large-scale public interactive installations. In doing so, we specifically highlight the possibilities in relation to designing for affective experience and engaging interaction that advocate for a longterm interactive experience.
Localizing fluorophore (centroid) inside a scattering medium by depth perturbation

Abstract. Fluorescence molecular tomography (FMT) imaging can be used to determine the location, size, and biodistribution of fluorophore biomarkers inside tissues. Yet when using FMT in the reflectance geometry it is challenging to accurately localize fluorophores. A depth perturbation method is proposed to determine the centroid of fluorophore inside a tissue-like medium. Through superposition of a known thin optical phantom onto the medium surface, the fluorophore depth is deliberately perturbed and signal localization is improved in a stable way. We hypothesize that the fluorophore centroid can be better localized through use of this fluorescent intensity variation resulting from the depth perturbation. This hypothesis was tested in tissue-like phantoms. The results show that a small-size fluorophore inclusion (1.2 mm3 volume, depth up to 4.8 mm) can be localized by the method with an error of 0.2 to 0.3 mm. The method is also proven to be capable of handling multiple fluorescent inclusion conditions with the assistance of other strategies. Additionally, our further studies showed that the method’s performance in the presence of background fluorophores indicated that the small inclusion could be located at a 1.8 (3.8) mm depth with accurate localization only when its concentration was not <10 (100) times the background level.
Breastfeeding and Employment: An Assessment of Employer Attitudes

Both research and anecdotal reports suggest that maternal employment is associated with failure to initiate breastfeeding and early breastfeeding attrition. The objective of this studywas to describe the experience with and attitudes toward breastfeeding of a sample of employers in a small Midwestern city in the United States. Based on an analysis of 85 mail-out questionnaires, we found that less than half of the employers had personal experience with breastfeeding. A large percentage of the sample, however, indicated that they would be willing to facilitate women who wished to breastfeed or express milk in the workplace. However, these employers also stated that they saw little value to their business of supporting breastfeeding in the work environment. Thus, enhancement of breastfeeding opportunity in the work environment may come as a result of public and employer education but, more likely, will require some type of directive from official sources.
An X-Band Transmitter For Small Satellites

An X-band QPSK transmitter designed for data rates up to 150 Mbps for small satellites with power, mass and size constraints is described in this paper. A direct modulation method where the baseband data directly modulate the X-band carrier is applied to the development of the X-band transmitter. This method can reduce the complexity and size of the hardware. 14 W (41.5 dBm) RF output power of the X-band transmitter at 8.2 GHz center frequency is obtained by a solid state power amplifier (SSPA).
The Inspired Sinewave Technique: A Comparison Study With Body Plethysmography in Healthy Volunteers

The inspired sinewave technique is a noninvasive method to measure airway dead space, functional residual capacity, pulmonary blood flow, and lung inhomogeneity simultaneously. The purpose of this paper was to assess the repeatability and accuracy of the current device prototype in measuring functional residual capacity, and also participant comfort when using such a device. To assess within-session repeatability, six sinewave measurements were taken over two-hour period in 17 healthy volunteers. To assess day-to-day repeatability, measurements were taken over 16 days in 3 volunteers. To assess accuracy, sinewave measurements were compared to body plethysmography in 44 healthy volunteers. Finally, 18 volunteers who experienced the inspired sinewave device, body plethysmography and spirometry were asked to rate the comfort of each technique on a scale of 1–10. The repeatability coefficients for dead space, functional residual capacity, and blood flow were 48.7 ml, 0.48L, and 2.4L/min respectively. Bland-Altman analyses showed a mean BIAS(SD) of −0.68(0.42)L for functional residual capacity when compared with body plethysmography. 14 out of 18 volunteers rated the inspired sinewave device as their preferred technique. The repeatability and accuracy of functional residual capacity measurements were found to be as good as other techniques in the literature. The high level of comfort and the non-requirement of patient effort meant that, if further refined, the inspired sinewave technique could be an attractive solution for difficult patient groups such as very young children, elderly, and ventilated patients.
Low-Frequency Noise Characteristics of In-Doped ZnO Ultraviolet Photodetectors

We report the growth of vertically aligned indium-doped ZnO (IZO) nanorods on a glass substrate using a low-temperature hydrothermal method. An IZO nanorod metal-semiconductor-metal (MSM) ultraviolet (UV) photodetector (PD) was also fabricated. It was found that the UV-to-visible rejection ratio of the fabricated PD was ~109 when biased at 1 V with a sharp cutoff at 390 nm. With an incident light wavelength of 390 nm and an applied bias of 1 V, it was found that measured responsivity of the PD was 2.5 A/W. Furthermore, it was also found that the noise equivalent power and detectivity of the fabricated IZO nanorod MSM PD were 1.42×10-10 W and 1.44×1011 cm·Hz0.5·W-1, respectively.
Blood pressure, heart rate, hormonal and other acute responses to rubber-ring castration and tail docking of lambs

Abstract AIM: To examine cardiovascular, hormonal and other physiological responses of 2-month-old lambs to rubber-ring castration and tail docking. METHODS: Twenty-two male lambs, well accustomed to handling and prepared with femoral artery and jugular vein can- nulae, were studied during a 5 h control period and, at least 2 days later, for 1 h before and 4 h after castration and tail docking using rubber rings. Pressure recordings were made via femoral cannulae and blood samples for analysis of plasma constituents were taken from jugular cannulae. RESULTS: Mean systolic, diastolic and mean arterial blood pressure, heart rate and the plasma concentrations of adrenocorticotropic hormone (ACTH) and cortisol all increased markedly during the first 1 h after ring castration and tail docking. Although plasma ACTH and cortisol concentrations had returned to control levels by 2.5-3 h, blood pressures and heart rate were still elevated 4 h after ring application. In contrast, there were no significant changes in mean plasma concentrations of renin, electrolytes, minerals, glucose, lactate, urea, creatinine, total carbon dioxide and total proteins, plasma osmolality or the haematocrit after ring application. There were no significant changes in the mean values for any parameter during the 5 h control period or the 1 h period before ring application. CONCLUSION: Systolic, diastolic and mean arterial blood pressure and heart rate may be more sensitive than plasma ACTH or cortisol concentrations as indices of low-grade pain induced by ring castration and tail docking. Alternatively, it is possible that by 4 h after ring placement a small shift in sympathetic tone still persists in the absence of low-grade pain.
Glucagon-like peptide-1 7-36 amide and peptide YY from the L-cell of the ileal mucosa are potent inhibitors of vagally induced gastric acid secretion in man.

BACKGROUND Glucagon-like peptide (GLP-1) 7-36 amide and peptide YY (PYY) from the L-cell of the ileal mucosa are potent inhibitors of gastric acid secretion in man. It is not clear, however, by which mechanism(s) they inhibit acid secretion. In dogs the inhibitory effect of PYY on acid secretion may be mediated mainly through neural pathways. The mechanism of action of GLP-1 might be similar. The aim of the present study was to examine the effects of GLP-1 might be similar. The aim of the present study was to examine the effects of GLP-1 and PYY on the vagally induced gastric acid secretion in man. METHODS A modified sham feeding technique, chew and spit, was used. Six healthy volunteers were randomly assigned to receive intravenous infusion of saline, GLP-1 (41 pmol/kg/h), or peptide YY (50 pmol/kg/h). RESULTS The infusion of GLP-1 and PYY resulted in plasma concentrations of 60 +/- 9 pmol/l and 84 +/- 11 pmol/l, respectively. GLP-1 and PYY both significantly inhibited the intergrated acid output by 67 +/- 6% and 68 +/- 9%, respectively, compared with the integrated outputs in a control experiment with saline infusion. Serum gastrin and plasma somatostatin concentrations remained unchanged during saline, GLP-1, and PYY infusions. CONCLUSIONS GLP-1 and PYY are both potent inhibitors of the cephalic phase of acid secretion, indicating that at least part of the inhibitory effect of GLP-1 and PYY in man is mediated through neural pathways. Furthermore, the inhibitory effect seems to be independent of circulating concentrations of gastrin and somatostatin.
Tbx20 dose-dependently regulates transcription factor networks required for mouse heart and motoneuron development

To elucidate the function of the T-box transcription factor Tbx20 in mammalian development, we generated a graded loss-of-function series by transgenic RNA interference in entirely embryonic stem cell-derived mouse embryos. Complete Tbx20 knockdown resulted in defects in heart formation, including hypoplasia of the outflow tract and right ventricle, which derive from the anterior heart field (AHF), and decreased expression of Nkx2-5 and Mef2c, transcription factors required for AHF formation. A mild knockdown led to persistent truncus arteriosus (unseptated outflow tract) and hypoplastic right ventricle, entities similar to human congenital heart defects, and demonstrated a critical requirement for Tbx20 in valve formation. Finally, an intermediate knockdown revealed a role for Tbx20 in motoneuron development, specifically in the regulation of the transcription factors Isl2 and Hb9, which are important for terminal differentiation of motoneurons. Tbx20 could activate promoters/enhancers of several genes in cultured cells, including the Mef2c AHF enhancer and the Nkx2-5 cardiac enhancer. The Mef2c AHF enhancer relies on Isl1- and Gata-binding sites. We identified a similar Isl1 binding site in the Nkx2-5 AHF enhancer, which in transgenic mouse embryos was essential for activity in a large part of the heart, including the outflow tract. Tbx20 synergized with Isl1 and Gata4 to activate both the Mef2c and Nkx2-5 enhancers, thus providing a unifying mechanism for gene activation by Tbx20 in the AHF. We conclude that Tbx20 is positioned at a critical node in transcription factor networks required for heart and motoneuron development where it dose-dependently regulates gene expression.
