Assessment of Hand Function as a Tool for Planning a Rehabilitation Program in Scleroderma Patient a Case Report
Authors: Nugroho Virginia Ainurridlo , Ridwan Muhammad , Rahmad Rahmad 
Published: July 2024

Scleroderma causes reduced versatility and the snugness of the skin due to cutaneous thickening and solidification (sclerosis). Scleroderma affects productivity, particularly hand-related work. A 29 years old man with scleroderma presented pain, contracture of his wrists and fingers, sclerodactyly, hardened skin, tightness, as well as shiny and dry skin. These manifestations decrease hand function, resulting in difficulty doing ADL and his job as a porter. Scleroderma was diagnosed one month prior. The planned treatments are TENS to decrease the pain, USD and hand exercise to increase ROM, Mc mennel and connective tissue massage, home exercise, vocational modification and occupational therapy to maximize the hand function and ADL, and psychotherapy to increase his self-confidence. MHOQ and HAMIS are used to Monitor and evaluate hand function. The assessment before therapy are right side HAMIS : 12; left side HAMIS : 11; VAS : 4; MHQ (Hand function 35% ; ADL 60%; work 30%; Pain 90%; aesthetic 55%; satisfaction 45%) . After 2 month, right side HAMIS : 10; left side HAMIS : 10; VAS : 1 ; MHQ (Hand function 45% ; ADL 72%; work 40%; Pain 40%; aesthetic 55%; satisfaction 70%). HAMIS and MHOQ in scleroderma patients could be used as an accurate assessment tool for planning rehabilitation treatment. The questionnaires can be used as guidelines for modifying the appropriate assistive device for ADL and patient work.
Chimpanzee nesting patterns in savanna habitat: Environmental influences and preferences
Authors: Hernandez‐Aguilar R. Adriana , Moore Jim , Stanford Craig B. 
Published: May 2013

AbstractData on chimpanzee (Pan troglodytes) nesting patterns were collected in Issa, Ugalla, western Tanzania. Ugalla is one of the driest, most open, and seasonal habitats inhabited by chimpanzees. We investigated the physical characteristics of nests and trees used for nesting to understand environmental influences on nest building and identify the characteristics preferred by the chimpanzees and the basis for such preferences. We analyzed 2,167 nests and 1,523 nesting trees. Most nests were built in the middle section of the tree crown and close to the tree trunk, and used a single tree in construction. Some physical characteristics of nests (e.g., distance from tree trunk) seemed to be the result of constraints imposed by tree structure. Issa chimpanzees preferred tall trees with high first branches for nesting supporting the hypothesis that elevated height of a sleeping place is a predator defense strategy. The height from the ground to the first branch showed less variation than either tree height or crown height and correlated weakly with tree height, suggesting that height from the ground to the first branch may be a more important factor than tree height alone in selecting a tree in which to nest. As in other study sites, the chimpanzees used tree species in proportions that did not correspond to their abundance suggesting tree species preference. We report for the first time that chimpanzees directionally oriented their nests and propose that this may be to maximize sunlight. We compare our data to those of other chimpanzee study sites. Am.

Preparation and colloidal properties of an aqueous acetic acid lignin containing polyurethane surfactant
Authors: Wang Haihua , Zou Jing , Shen Yiding , Fei Guiqiang , Mou Jing 
Published: May 2013

ABSTRACTAqueous acetic acid lignin containing polyurethane (ALPU) surfactants were prepared by the replacement of some hydrophobic poly(caprolactone diol) with different concentrations of multifunctional acetic acid lignin (AL), and with dimethylol propionic acid as the hydrophilic segment. The infrared spectra, together with thermogravimetric analysis, demonstrated the presence of AL in the polyurethane (PU) chains. In addition, the effects of the AL concentration on the particle size, morphology, rheological behavior, and surface activity of the dispersions were investigated. The ALPU particles displayed a spherical morphology. With increasing AL concentration from 0 to 10 wt %, the particle size increased from 36 to 260 nm, and the unimodal distribution was detected for ALPU10 with a 10 wt % AL addition. The viscosity and shear‐thinning behavior of the ALPU dispersions decreased, and the lowest surface tension and critical micelle concentration (cmc) were detected for ALPU10. However, when the AL concentration was 15 wt % (ALPU15), the surface tension and cmc increased. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 130: 1855–1862, 2013
Mapping Subsurface Archaeology with SAR
Authors: Morrison Keith 
Published: May 2013

ABSTRACTSubSAR is a new scheme for mapping subsurface features with synthetic aperture radar (SAR) at large stand‐off distances applicable to airborne and satellite measurements. This is in sharp contrast to current techniques, where discrimination relies on close‐proximity measurement of the scene, usually with a ground‐based system. The scheme discriminates between surface and subsurface returns using a novel application of differential SAR interferometry (DInSAR). It is based on the differing phase histories of surface and subsurface features. Whereas the latter experiences phase delays in sympathy with variations in soil moisture, these are absent from the surface feature's phase history. To assess the predictions and performance of the model against measurements, a laboratory investigation was carried out at the GB‐SAR Microwave Measurement Facility. C‐band VV tomographic profiling (TP) was collected of a trihedral and a pile of cobble stones, buried in a sandy soil. The TP imagery displayed the vertical backscattering pattern through the soil, allowing separation of returns from the soil and buried features. Known amounts of water were added incrementally to the soil to precisely quantify DInSAR phase and backscatter behaviours of the soil and buried features. The measurements confirmed the two central tenets of the model: (i) a linear relationship between soil moisture and DInSAR phase, and (ii) that this is independent of incidence angle. Application and performance of the scheme applied to mapping subsurface archaeology is discussed. A low‐level product would deliver a basic distinction between surface and subsurface features in SAR imagery. The high‐level product, with supporting ground‐truth data, could additionally deliver the depth of a feature. Copyright © 2013 John Wiley & Sons, Ltd.

Published: May 2013

ABSTRACTThis paper describes a simple, rapid and sensitive liquid chromatography/tandem mass spectrometry assay for the determination of aliskiren in human plasma using nevirapine as an internal standard. Analyte and the internal standard were extracted from 100 μL of human plasma via liquid–liquid extraction using tert‐butyl methyl ether. The chromatographic separation was achieved on a C18 column using a mixture of acetonitrile and 0.1% formic acid (90:10, v/v) as the mobile phase at a flow rate of 0.9 mL/min. The calibration curve obtained was linear (r2 ≥ 0.99) over the concentration range of 0.10–1013 ng/mL. Method validation was performed as per US Food and Drug Administration guidelines and the results met the acceptance criteria. A run time of 2.2 min for each sample made it possible to analyze a greater number of samples in a short time, thus increasing the productivity. The proposed method was found to be applicable to clinical studies. Copyright © 2013 John Wiley & Sons, Ltd.
Capillary networks in tumor angiogenesis: From discrete endothelial cells to phase‐field averaged descriptions via isogeometric analysis
Authors: Vilanova Guillermo , Colominas Ignasi , Gomez Hector 
Published: May 2013

SUMMARYTumor angiogenesis, the growth of new capillaries from preexisting ones promoted by the starvation and hypoxia of cancerous cell, creates complex biological patterns. These patterns are captured by a hybrid model that involves high‐order partial differential equations coupled with mobile, agent‐based components. The continuous equations of the model rely on the phase‐field method to describe the intricate interfaces between the vasculature and the host tissue. The discrete equations are posed on a cellular scale and treat tip endothelial cells as mobile agents. Here, we put the model into a coherent mathematical and algorithmic framework and introduce a numerical method based on isogeometric analysis that couples the discrete and continuous descriptions of the theory. Using our algorithms, we perform numerical simulations that show the development of the vasculature around a tumor. The new method permitted us to perform a parametric study of the model. Furthermore, we investigate different initial configurations to study the growth of the new capillaries. The simulations illustrate the accuracy and efficiency of our numerical method and provide insight into the dynamics of the governing equations as well as into the underlying physical phenomenon.

The Relation Between Antisocial and Borderline Personality Symptoms and Early Maladaptive Schemas in a Treatment Seeking Sample of Male Substance Users
Authors: Shorey Ryan C. , Anderson Scott , Stuart Gregory L. 
Published: May 2013

Individuals with substance use disorders are more likely to have antisocial and borderline personality disorder than non‐substance abusers. Recently, research has examined the relations between early maladaptive schemas and personality disorders, as early maladaptive schemas are believed to underlie personality disorders. However, there is a dearth of research on the relations between early maladaptive schemas and personality disorders among individuals seeking treatment for substance abuse. The current study examined the relations among early maladaptive schemas and antisocial and borderline personality within in a sample of men seeking substance abuse treatment (n = 98). Results demonstrated that early maladaptive schema domains were associated with antisocial and borderline personality symptoms. Implications of these findings for substance use treatment and research are discussed. Copyright © 2013 John Wiley & Sons, Ltd.Key Practitioner Message

Antisocial (ASPD) and Borderline (BPD) personality disorder symptoms are prevalence among individuals seeking substance abuse treatment.
Early maladaptive schemas are believed to underlie the development of ASPD and BPD symptoms, and are also prevalence among individuals seeking substance use treatment.
Findings from the current study suggest that specific early maladaptive schema domains predict ASPD and BPD symptoms in a substance abuse treatment seeking sample of adult males.
The treatment of ASPD and BPD among men seeking substance use treatment may want to focus on early maladaptive schemas.

Published: May 2013

K(D0.12H0.88)2PO4 crystals were chosen to be used for quadratic nonlinear medium of wideband frequency doubling at 1 μm. A key limitation on this application is that little information can be found in the previous reports. In this work, growth as well as structural and optical properties of this crystal were investigated in detail. Experimental results in comparison with KDP indicate that lattice parameter along a‐axis changes much more than lattice parameter c and infra‐red absorption edge shift by 0.08 μm accompanied with increasing of transmittance in the whole region. With the introduction of deuterium atom, peak of ν1(PO4) shifts to lower wave number and transverse stimulated Raman scattering was effectively suppressed. Extra‐ordinary and ordinary indices were also measured as function of wavelength. Good crystalline perfection and great performance of damage threshold also indicate that 12%‐DKDP is an appropriate choice in the application of wideband frequency doubling at 1 μm.
A Simple Synthetic Access to Differently 4‐Substituted Neu5Ac2en Glycals Combining Elements of Molecules with Anti‐Neuraminidase Activity
Authors: Allevi Pietro , Rota Paola , Agnolin Irene Sofia , Gregorio Antonio , Anastasia Mario 
Published: May 2013

AbstractA protocol for direct access to C‐4‐functionalized Neu5Ac2en derivatives by allylic substitution of an α‐acetoxy group with various nucleophiles is reported. The DANA acetamido group is exchanged for a trifluoroacetylamido group (as in FANA) to avoid the formation of a stable 4,5‐oxazoline. With thiols, the reaction involves an initial attack at the anomeric carbon (Ferrier reaction) under kinetic control, followed by an equilibration of the nucleophile to the thermodynamically more stable 4‐position.

AbstractSelenoisotryptophan and its higher homologues were synthesized by Sonogashira coupling of iodophenyl methyl selenide and alkynyloxazolidines followed by iodocyclization as the key step. Sonogashira coupling of 3‐iodobenzoselenophene with ethynyloxazolidine allowed the synthesis of selenohomotryptophan.
Aromatic Oligoamides with a Rare ortho‐Connectivity: Synthesis and Study of ortho‐Arylopeptoids
Authors: Hjelmgaard Thomas , Nielsen John 
Published: May 2013

AbstractEven though aromatic oligoamides composed of aromatic amino acids in a “one‐way sequence” attract ever increasing research interest, backbones connected through ortho‐linked aromatics remain rare. Herein, we present the first synthesis and study of N‐alkylated ortho‐aminomethyl‐benzamides termed “ortho‐arylopeptoids”. The ortho‐arylopeptoids may, with a few exceptions, be synthesized either in solution or on solid‐phase using unique and highly efficient submonomer methods with similar levels of high generality and efficiency to those previously demonstrated for meta‐ and para‐arylopeptoids. NMR studies indicated a more restricted rotation about the amide bonds in ortho‐arylopeptoids, presumably due to a more congested backbone structure resulting from the ortho‐connectivity pattern. Intriguingly, tert‐butyl and phenyl side chains offer complete control over the amide conformations; whereas arylopeptoid residues with tert‐butyl side chains adopt a 100 % cis amide conformation, the opposite 100 % trans amide conformation was observed in arylopeptoids with phenyl side chains. The tert‐butyl moiety can furthermore serve as a protecting group during synthesis, which can later be removed to allow the amide to adopt a 100 % trans conformation instead.

Authors: Kanakam Natalie , Krug Isabel , Raoult Charlotte , Collier David , Treasure Janet 
Published: May 2013

AbstractObjectivesEmotional processing difficulties are potential risk markers for eating disorders that are also present after recovery. The aim of this study was to examine these traits in twins with eating disorders.MethodsThe Reading the Mind in the Eyes test, Emotional Stroop task and the Difficulties in Emotion Regulation Scale were administered to 112 twins with and without eating disorders (DSM IV‐TR eating disorder criteria). Generalised estimating equations compared twins with eating disorders against unaffected co‐twins and control twins, and within‐pair correlations were calculated for clinical monozygotic (n = 50) and dizygotic twins (n = 20).ResultsEmotion recognition difficulties, attentional biases to social threat and difficulties in emotion regulation were greater in twins with eating disorders, and some were present in their unaffected twin siblings. Evidence for a possible genetic basis was highest for emotion recognition and attentional biases to social stimuli.ConclusionEmotion recognition difficulties and sensitivity to social threat appear to be endophenotypes associated with eating disorders. However, the limited statistical power means that these findings are tentative and require further replication. Copyright © 2013 John Wiley & Sons, Ltd and Eating Disorders Association.
Delay‐oriented power‐aware routing in wireless ad hoc networks
Authors: Huang Haojun , Yin Hao , Zhang Junbao , Qian Feng 
Published: May 2013

AbstractIn this letter, we propose an on‐demand delay‐oriented power‐aware routing protocol to reduce the total consumed energy and meet the desired delay requirement in wireless ad hoc networks. In contrast to previous research, we adaptively build different delay‐oriented routing entries over several fixed discrete power levels, and select the route with the minimum power level for data delivery. Moreover, we use cross‐layer power control strategy to transmit data packets and control packets of network layer and medium access control layer for energy reduction. Simulation results demonstrate that the proposed scheme significantly outperforms other schemes in terms of network lifetime, average delivery delay and packet delivery ratio.

Published: May 2013

ABSTRACTMachine‐to‐machine networks are spreading over every sector of our society due to their self‐organisation capabilities. In these networks, thousands of devices are left unattended for years of operation without the possibility of human intervention. In this sense, every step forward into avoiding early exhaustion of the network nodes is of paramount importance. We have introduced a novel authentication scheme that is able to discard non‐intended and/or non‐legitimate packets just after the reception of the physical preamble. This proposal was shown to yield enormous energy saving with regard to both node exhaustion attacks and normal network operation. In this paper, we extend that work with a novel synchronisation protocol that addresses previous desynchronisation issues. Besides, we analyse and propose the more appropriate deployment parameters that maximise the overall energy savings. We also detail the necessary key generation and key updating processes required to manage the in use keying material. Moreover, we show how to fit the proposed mechanism into the IEEE 802.15.4e amendment to the IEEE 802.15.4‐2006 standard, as many companies have decide to go for this technology for the development of machine‐to‐machine networks.Copyright © 2013 John Wiley & Sons, Ltd.

Large‐amplitude internal tides, solitary waves, and turbulence in the central Bay of Biscay
Authors: Xie X. H. , Cuypers Y. , Bouruet‐Aubertot P. , Ferron B. , Pichon A. , Lourenço A. , Cortes N. 
Published: May 2013

AbstractMicrostructure and fine‐scale measurements collected in the central Bay of Biscay during the MOUTON experiment are analyzed to investigate the dynamics of internal waves and associated mixing. Large‐amplitude internal tides (ITs) that excite internal solitary waves (ISWs) in the thermocline are observed. ITs are dominated by modes 3 and 4, while ISWs projected on mode 1 that is trapped in the thermocline. Therein, ITs generate a persistent narrow shear band, which is strongly correlated with the enhanced dissipation rate in the thermocline. This strong dissipation rate is further reinforced in the presence of ISWs. Dissipation rates during the period without ISWs largely agree with the MacKinnon‐Gregg scaling proposed for internal wavefields dominated by a low‐frequency mode, while they show poor agreement with the Gregg‐Henyey parameterization valid for internal wavefields close to the Garrett‐Munk model. The agreement with the MacKinnon‐Gregg scaling is consistent with the fact that turbulent mixing here is driven by the low‐frequency internal tidal shear.
Effectiveness of an 8‐week exercise programme on pain and specificity of neck muscle activity in patients with chronic neck pain: A randomized controlled study

Published: May 2013

AbstractBackgroundAlthough exercise can be effective for relief of neck pain, little is known about the effect of exercise on the neural control of neck muscles.MethodsA randomized controlled trial was conducted on 46 women with chronic neck pain to investigate the immediate effectiveness of an 8‐week exercise programme on pain and directional specificity of neck muscle activity. At baseline, the patients completed questionnaires including the neck disability index (NDI) and performed a circular contraction of their head in the horizontal plane at 15 N force, with continuous change in force direction in the range 0–360°. Electromyography (EMG) was recorded from the sternocleidomastoid (SCM) and splenius capitis (SCap) muscles. Tuning curves of the EMG amplitude were computed, which depicts muscle activity over a range of force directions. The mean point of the tuning curves defined a directional vector, which determined the specificity of muscle activity. Patients were randomly assigned either to a training or control group.ResultsA significant between‐group difference in the change in NDI was observed. A reduction in NDI was observed following training (pre: 18.2 ± 7.4; post: 14.1 ± 6.5; p < 0.01) but not for the control group (pre: 17.5 ± 6.3; post: 16.6 ± 7.4). The training group showed higher specificity of muscle activity post‐intervention (pre: 18.6 ± 9.8%, post: 24.7 ± 14.3%; p < 0.05), whereas no change occurred for the control group (pre: 19.4 ± 11.9%, post: 18.2 ± 10.1%).ConclusionAn exercise programme that aims to enhance motor control of the cervical spine improves the specificity of neck muscle activity and reduces pain and disability in patients with neck pain.
