A Compact Tri-Band Monopole Antenna With Single-Cell Metamaterial Loading

A compact tri-band planar monopole antenna is proposed that employs reactive loading and a ¿defected¿ ground-plane structure. The reactive loading of the monopole is inspired by transmission-line based metamaterials (TL-MTM), which enables the loaded antenna to operate in two modes. The first resonance exhibits a dipolar mode over the lower WiFi band of 2.40 GHz - 2.48 GHz, and the second resonance has a monopolar mode over the 5.15-5.80 GHz upper WiFi band. Full-wave analysis shows that the currents of the two modes are orthogonal to each other, resulting in orthogonal radiation patterns in the far field. The feature of a ¿defected¿ ground-plane, formed by appropriately cutting an L-shaped slot out of one of the CPW ground-planes, leads to the third resonance that covers the WiMAX band at 3.30-3.80 GHz. Air bridges at the intersection between the antenna and the CPW feedline ensure a balanced current. A fabricated prototype has compact dimensions of 20.0 mm × 23.5 mm × 1.59 mm, and exhibits good agreement between the measured and simulated S parameters and radiation patterns. The measured radiation efficiencies are 67.4% at 2.45 GHz, 86.3% at 3.50 GHz and 85.3% at 5.50 GHz.
Uniform Controllability of Scalar Conservation Laws in the Vanishing Viscosity Limit

We deal with viscous perturbations of scalar conservation laws on a bounded interval with a general flux function $f$ and a small dissipation coefficient $\varepsilon$. Acting on this system on both endpoints of the interval, we prove global exact controllability to constant states with nonzero speed. More precisely, we construct boundary controls so that the solution is driven to the targeted constant state, and we moreover require these controls to be uniformly bounded as $\varepsilon \rightarrow 0^+$ in an appropriate space. For general (nonconvex) flux functions this can be done for sufficiently large time, and for convex fluxes $f$, we have a precise estimate on the minimal time needed to control.
Use of Contrasting Fluorescent Dye as Counterstain in Fixed Tissue Preparations

Summary A counterstaining method is described that gives a contrasting reddish-orange background when used with fluorescein-labeled antibody systems. It curtails non-specific fluorescence in tissues and tissue cultures. The possibility of a nonspecific protein-protein reaction is discussed. This reaction apparently plays no part in the serological system to which it has been added.
The Minkowski approach for choosing the distance metric in geographically weighted regression

ABSTRACT In this study, the geographically weighted regression (GWR) model is adapted to benefit from a broad range of distance metrics, where it is demonstrated that a well-chosen distance metric can improve model performance. How to choose or define such a distance metric is key, and in this respect, a ‘Minkowski approach’ is proposed that enables the selection of an optimum distance metric for a given GWR model. This approach is evaluated within a simulation experiment consisting of three scenarios. The results are twofold: (1) a well-chosen distance metric can significantly improve the predictive accuracy of a GWR model; and (2) the approach allows a good approximation of the underlying ‘optimal distance metric’, which is considered useful when the ‘true’ distance metric is unknown.
Mussel‐Inspired Coating of Polydopamine Directs Endothelial and Smooth Muscle Cell Fate for Re‐endothelialization of Vascular Devices

Polydopamine (PDAM), a mussel adhesive protein inspired coating that can be easily deposited onto a wide range of metallic, inorganic, and organic materials, gains interest also in the field of biomaterials. In this work, PDAM is applied as coating on 316L stainless steel (SS) stents and the response of cells of the blood vessel wall, human umbilical vein endothelial cell (HUVEC), and human umbilical artery smooth muscle cell (HUASMC) as predictors for re‐endothelialization is tested. It is found that the PDAM‐modified surface significantly enhances HUVEC adhesion, proliferation, and migration, release of nitric oxide (NO), and secretion of prostaglandin I2 (PGI2). Additionally, the PDAM‐modified surface shows a remarkable ability to decrease the adhesion and proliferation of HUASMCs. As a blood‐contacting material, the PDAM tends to improve the hemocompatibility compared with the substrate 316L SS. It is noteworthy that the PDAM coating shows good resistance to the deformation behavior of compression and expansion of a stent. These data suggest the potential of PDAM as a blood‐contacting material for the application in vascular stents or grafts.
Iatrogenic trauma to oral tissues.

BACKGROUND Iatrogenic trauma can be defined as any trauma that has been induced by the dentist's activity, manner, or therapy. The aim of this article is to present traumatic oral tissue lesions of iatrogenic origin. METHODS Thirteen cases of chemical (due to ferric sulfate and formocresol), physical (due to orthodontic wires and appliances), and thermal (due to electrosurgery) injuries to the oral tissues are reported. RESULTS Chemical, physical, and thermal injuries in the oral, gingival, or palatinal mucosa of iatrogenic origin can exhibit various clinical features. The management of traumatic injuries is dependent on the severity of the involvement in the periodontal tissues. While, in most cases, the elimination of the offending agent and symptomatic therapy were sufficient, in severe cases, or when the injury resulted in permanent defects, periodontal surgery and regenerative therapy may be necessary. CONCLUSIONS The skill, experience, and up-to-date knowledge of dentists are the main factors to prevent possible iatrogenic traumas. Although "To err is human," careful practice is very important for the principle "Primum non nocere" ("First do no harm").
The protective effect of hypotaurine and cysteine sulphinic acid on peroxynitrite-mediated oxidative reactions

The protective activity of hypotaurine (HTAU) and cysteine sulphinic acid (CSA) on peroxynitrite-mediated oxidative damage has been assessed by monitoring different target molecules, i.e. tyrosine, dihydrorhodamine-123 (DHR) and glutathione (GSH). The inhibition of tyrosine oxidation exerted by HTAU and CSA both in the presence and the absence of bicarbonate can be ascribed to their ability to scavenge hydroxyl (•OH) and carbonate (CO3•−) radicals. HTAU and CSA also reduce tyrosyl radicals, suggesting that this repair function of sulphinates might operate as an additional inhibiting mechanism of tyrosine oxidation. In the peroxynitrite-dependent oxidation of DHR, the inhibitory effect of HTAU was lower than that of CSA. Moreover, while HTAU and CSA competitively inhibited the direct oxidation of GSH by peroxynitrite, HTAU was again poorly effective against the oxidation of GSH mediated by peroxynitrite-derived radicals. The possible involvement of secondary reactions, which could explain the difference in antioxidant activity of HTAU and CSA, is discussed.
Segmentation multi-vues par coupure de graphes

Dans cet article, nous abordons le probleme de la segmentation simultanee d'images lorsque plusieurs cameras calibrees et synchronisees observent la meme scene. Nous proposons une nouvelle approche permettant de propager l'information de segmentation de maniere coherente entre les vues. Pour cela, le probleme de segmentation est formule comme un probleme d'etiquetage en deux regions fond et forme des pixels de l'image, resolu avec une methode de coupe de graphe. Contrairement a de nombreuses approches de l'etat de l'art, notre methode ne necessite pas de reconstruction 3D dense de l'objet mais plus simplement un echantillonnage eparse de l'espace 3D. Une evaluation complete est effectuee sur des donnees statiques standard. Les resultats obtenus montrent l'interet de la methode qui obtient des resultats equivalents a ceux de l'etat de l'art mais avec beaucoup moins de points de vue.
Cost-effectiveness analysis should continually assess competing health care options especially in high volume environments like cataract surgery

Context: Cost-effectiveness analysis should continually assess competing health care options especially in high volume environments like cataract surgery. Aims: To compare the cost effectiveness of phacoemulsification (PE) versus manual small-incision cataract surgery (MSICS). Settings and Design: Prospective randomized controlled trial. Tertiary care hospital setting. Subjects and Methods: A total of 52 consenting patients with age-related cataracts, were prospectively recruited, and block randomized to PE or MSICS group. Preoperative and postoperative LogMAR visual acuity (VA), visual function-14 (VF-14) score and their quality-adjusted life years (QALYs) were obtained, and the change in their values calculated. These were divided by the total cost incurred in the surgery to calculate and compare the cost effectiveness and cost utility. Surgery duration was also compared. Statistical Analysis Used: Two group comparison with Student's t-test. Significance set at P < 0.05; 95% confidence interval (CI) quoted where appropriate. Results: Both the MSICS and PE groups achieved comparative outcomes in terms of change (difference in mean [95% CI]) in LogMAR VA (0.03 [−0.05−0.11]), VF-14 score (7.92 [−1.03−16.86]) and QALYs (1.14 [−0.89−3.16]). However, with significantly lower costs (INR 3228 [2700–3756]), MSICS was more cost effective, with superior cost utility value. MSICS was also significantly quicker (10.58 min [6.85–14.30]) than PE. Conclusions: MSICS provides comparable visual and QALY improvement, yet takes less time, and is significantly more cost-effective, compared with PE. Greater push and penetration of MSICS, by the government, is justifiably warranted in our country.
Low Cost Framework for Non-intrusive Home Energy Monitoring and Research

This paper presents a low-cost framework for non-intrusive home energy monitoring and research built on top of Non-Intrusive Load Monitoring (NILM) concepts and techniques. NILM solutions are already considered low-cost alternatives to the big majority of existing commercial energy monitors but the goal of this work is to make its cost even lower by using a mini netbook as a packaged solution. The mini netbook is installed in the home’s main circuit breaker panel and computes power consumption by reading current and voltage through the built-in sound card. At the same time, feedback to the users is provided using the 11’’ LCD screen as well as other built-in I/O modules. The meter is also capable of detecting changes in power consumption and tries to find out which appliance lead to that change. It is believed that such a system will not only be important as a tool for energy monitoring and feedback, but also serve as an open system that can be easily changed to accommodate and test new or existing non-intrusive load monitoring
Long-term effects of back extensor strengthening exercises on quality of life in women with osteoporosis

ABSTRACT The aim of the present study was to evaluate the long-term effect of back extensor strengthening exercises on health-related quality of life (QOL) in women with osteoporosis. In this randomized clinical trial, 183 women with osteoporosis were treated with pharmacotherapy and weight-bearing and balance-training exercises. The case group additionally performed back extensor exercises at home. Patients filled out the Persian version of the Short Form (SF-36) QOL questionnaire at baseline and 6 months post treatment. At the end, all physical and mental parameters of the SF-36 questionnaire improved significantly in the case group, except for one subscale of mental health, compared to the control group. In the control group, only some physical health dimensions (bodily pain, role limitation, physical function, vitality), and mental health status as a mental health subscale improved. In conclusion, considering a major impact of back extensor exercises on improving QOL in women with osteoporosis over the long term, these exercises should be prescribed in routine management of these patients.

Geomorphology Drives Amphibian Beta Diversity in Atlantic Forest Lowlands of Southeastern Brazil

Beta diversity patterns are the outcome of multiple processes operating at different scales. Amphibian assemblages seem to be affected by contemporary climate and dispersal-based processes. However, historical processes involved in present patterns of beta diversity remain poorly understood. We assess and disentangle geomorphological, climatic and spatial drivers of amphibian beta diversity in coastal lowlands of the Atlantic Forest, southeastern Brazil. We tested the hypothesis that geomorphological factors are more important in structuring anuran beta diversity than climatic and spatial factors. We obtained species composition via field survey (N = 766 individuals), museum specimens (N = 9,730) and literature records (N = 4,763). Sampling area was divided in four spatially explicit geomorphological units, representing historical predictors. Climatic descriptors were represented by the first two axis of a Principal Component Analysis. Spatial predictors in different spatial scales were described by Moran Eigenvector Maps. Redundancy Analysis was implemented to partition the explained variation of species composition by geomorphological, climatic and spatial predictors. Moreover, spatial autocorrelation analyses were used to test neutral theory predictions. Beta diversity was spatially structured in broader scales. Shared fraction between climatic and geomorphological variables was an important predictor of species composition (13%), as well as broad scale spatial predictors (13%). However, geomorphological variables alone were the most important predictor of beta diversity (42%). Historical factors related to geomorphology must have played a crucial role in structuring amphibian beta diversity. The complex relationships between geomorphological history and climatic gradients generated by the Serra do Mar Precambrian basements were also important. We highlight the importance of combining spatially explicit historical and contemporary predictors for understanding and disentangling major drivers of beta diversity patterns.
Haptoglobin and Hemopexin in Heme Detoxification and Iron Recycling

The acute phase reaction is an early response aimed at the defence of the organism and at the re-establishment of homeostasis in response to acute infection, inflammation and other pathological states (Kushner, 1982). The putative mechanism responsible for this reaction is based on an initial signal derived from macrophages and other cells that synthesize and secrete several factors (probably cytokines) capable of inducing, in hepatocytes, a series of events. One of the most important mediators of the liver acute phase response is the monokine Interleukin (IL)-6 (Gauldie et al., 1987). The acute phase response consists in a change in the concentration of several plasma proteins, generally synthesized in the liver, including 1-glycoprotein (AGP), complement factor C3, serum amyloid A, Haptoglobin and Hemopexin.
Power independent of number of slices (PINS) radiofrequency pulses for low‐power simultaneous multislice excitation

This communication describes radiofrequency pulses capable of performing spatially periodic excitation, inversion, and refocusing. The generation of such pulses either by multiplication of existing radiofrequency pulses by a Dirac comb function or by means of Fourier series expansion is described. Practical schemes for the implementation of such pulses are given, and strategies for optimizing the pulse profile at fixed pulse duration are outlined. The pulses are implemented using a spin‐echo sequence. The power deposition is independent of the number of slices acquired, and hence the power deposition per slice is considerably reduced compared to multislice imaging. Excellent image quality is obtained both in phantoms and in images of the human head. These pulses should find widespread application for multiplexed imaging, in particular at high static magnetic field strengths and for pulse sequences that have a high radiofrequency power deposition and could lead to dramatic increases in scanning efficiency.

Dose escalation of imatinib after failure of standard dose in Korean patients with metastatic or unresectable gastrointestinal stromal tumor.

OBJECTIVE We evaluated the results of imatinib dose escalation in patients with advanced gastrointestinal stromal tumors (GISTs) after disease progression on standard-dose imatinib. METHODS Clinical data from patients with metastatic or unresectable GISTs whose dose of imatinib was increased after disease progression on imatinib 400 mg/day were retrospectively reviewed. RESULTS The 24 patients studied had a median age of 52 years. Imatinib dosing was escalated to 600 mg/day in 12 patients, then to 800 mg/day in four patients. The other 12 patients had dose escalation directly to 800 mg/day. Two patients (8.3%) achieved a partial response, and seven (29.2%) had stable disease. Six-month progression-free and overall survival rates were 33.3 and 70.7%, respectively. Dose escalation to 600 or 800 mg/day was generally well tolerated. CONCLUSION Imatinib dose escalation is feasible and well tolerated in patients with advanced GIST who progress on standard-dose therapy, producing clinical benefit in approximately 37% of patients.
Transrectal ultrasound guided manipulation of the canine prostate with minimum intervention

The canine prostate is a widely used and well established animal model for the assessment of therapeutic effects of laser technology in the search for better options for the treatment of benign prostatic hyperplasia. Conventionally for such experiments, the canine prostate is approached by laparotomy or transperineal urethrotomy. We have demonstrated a technique involving the use of ultrasound guided biopsy of the liver and prostate, and percutaneous laser treatment of the prostate, which has proved to be effective in reducing adverse effects on the experimental animals but without compromising scientific requirements for the experiments. We conclude that state-of-the-art percutaneous procedures not only refine animal intervention significantly but are also technically feasible for most laser studies using the canine prostate as an experimental model in the live animal.
Efficient algorithms for sensor detachment in WMSNs

Target coverage is an important issue in wireless sensor networks (WSNs). This work copes with the target coverage problem which detaches a set of mobile sensors to targets efficiently. Given a set of disconnected targets with different quality of monitoring (QoM) and a set of mobile sensors which are distributed randomly in the networks, this paper develops two efficient algorithms for detaching mobile sensors to the targets such that the QoM of each target is satisfied. Performance study reveals that the proposed mechanisms outperform known mechanisms in terms of the satisfied QoMs of all targets and the movement cost of all mobile sensors as well as the life time of the wireless mobile sensor networks (WMSNs).
Fenton-like Oxidation of Acid Red 1 Solutions Using Heterogeneous Catalyst Based on Ball Clay

In this work, the Fenton-like decolorization of an azo dye, Acid Red 1 (AR1) by Fe-ball clay (Fe-BC) catalyst was studied. The effects of different reaction parameters such as initial iron ions loading on ball clay (BC), catalyst dosage, initial concentration of hydrogen peroxide (H2O2)0 and AR1 (AR1)0, reaction temperature and initial solution pH on the decolorization of AR1 were assessed. The best reacting conditions were found to be 1.0 wt. % of iron ions loading on BC, catalyst dosage = 5.0 g L -1 , initial solution pH = 2.5, (H2O2)0 = 12 mM, (AR1)0 of 50 mg L -1 at temperature 30 °C. Under these conditions, 99% decolorization efficiency of AR1 was achieved within 180 min of reaction. The results indicated that Fe-BC was a promising catalyst for the heterogeneous Fenton system.
Digital Watermarking for Telemedicine Applications: A Review

is an emerging science that can help in solving the modern global health problems. Exchanging medical images and Electronic Patient Records (EPR) between clinicians, specialists, and radiologists provides a platform for discussing and consulting diagnostic and therapeutic problems. Using Information and Communication Technologies (ICT) in the transmission of medical information for improving healthcare access, diagnosis, and treatment requires various means for security and privacy issues, since, digital information can be easily attacked to be duplicated and manipulated. Digital watermarking is a data hiding technique which used for improving the security of various multimedia applications and extensively investigated to protect the privacy of patients through telemedicine systems. This paper aims to provide a useful preview on telemedicine and the using of digital watermarking in this field.
