Intramuscular Adipose Tissue and the Functional Components of Sarcopenia in Hospitalized Geriatric Patients

Intramuscular adipose tissue (IMAT) could be an important missing value in the assessment of sarcopenia. This study tries to determine the relation between IMAT, muscle strength, functionality and mortality. In addition, the relation with nutritional status is screened. For six months, all patients admitted to the University Geriatric Center of Antwerp were evaluated for strength (hand grip), functionality (short physical performance battery—SPPB) and nutritional status. After one year, patients/relatives were contacted to obtain a current health status (mortality). A total of 303 patients were included at a mean age of 83.0 ± 6.4 years. The mean percentage of IMAT was 29.2% ± 13.0% (range 3.2%–86.2%). There was a negative correlation between IMAT and both grip strength and SPPB. SPPB was positively correlated with both grip strength and muscle mass. There was a positive correlation between IMAT and mortality. There was a negative correlation between grip strength, SPPB and mortality. IMAT did not have a clear relation with nutritional status. IMAT should be addressed in the work-up of sarcopenia, as it is correlated with muscle strength, functionality and mortality. In this cohort of hospitalized geriatric patients, there is a mean of about one-third of measured muscle volume that appears to be adipose tissue.
Dynamic changes in hydraulic conductivity in petioles of two savanna tree species: factors and mechanisms contributing to the refilling of embolized vessels

Diel variation in specific hydraulic conductivity (ks) was recorded in petioles of two savanna tree species, Schefflera macrocarpa and Caryocar brasiliense, from central Brazil. These two species have compound leaves with long petioles (10–30 cm). In both species, petiole ks decreased sharply with increasing transpiration rates and declining leaf water potentials (ψL) during the morning. Petiole ks increased during the afternoon while the plants were still transpiring and the water in the non-embolized vessels was still under tension. Dye experiments confirmed that in both species diel variation in ks was associated with embolism formation and repair. When transpiration was prevented in individual leaves, their petiole ks and water potential remained close to their maximum values during the day. When minimum daily ψL on selected branches was experimentally lowered by 0.2–0.6 MPa, the rate of ks recovery during the afternoon was slower in comparison with control branches. Several field manipulations were performed to identify potential mechanisms involved in the refilling of embolized petiole vessels. Removal of the cortex or longitudinal incisions in the cortex prevented afternoon recovery of ks and refilling of embolized vessels. When distilled water was added to petiole surfaces that had been abraded to partially remove the cuticle, ks increased sharply during the morning and early afternoon. Evidence of starch to sugar conversion in the starch sheath cells surrounding the vascular bundles of the petioles was observed during periods of rapid transpiration when the abundance of starch granules in the starch sheath cells surrounding the vascular bundles decreased. Consistent with this, petiole sugar content was highest in the early afternoon. The most parsimonious explanation of the field observations and the experimental results was that an increase in osmotically active solutes in cells outside the vascular bundles at around midday leads to water uptake by these cells. However, the concurrent increase in tissue volume is partially constrained by the cortex, resulting in a transient pressure imbalance that may drive radial water movement in the direction of the embolized vessels, thereby refilling them and restoring water flow. This study thus presents evidence that embolism formation and repair are two distinct phenomena controlled by different variables. The degree of embolism is a function of tension, and the rate of refilling a function of internal pressure imbalances.
Hindi-English Translation Memory System

This paper outlined the Hindi-English Translation Memory System as a tool to translate the Hindi texts into English by human translator using the already existing Hindi-English text pairs in the TM database. Translation memory(TM) systems were commercially available in the market in late 1990’s but the researches in this field have been in continuation since 1970’s. It is a database that consists of existing translations which can be later reused as a suggestion to the translator for translating a query.TM has evolved as an important area in the translation industry and is widely used among translators but not much of the works have been done for Indian languages in comparison to other foreign languages. This makes us feel the requirement of having such a tool that performs the translation of Hindi documentation into English which favors the recognition of the localized work in Hindi globally. The following methodologies are used in our system: - pre processing module that includes filtering and segmentation, retrieval module that employs N-gram statistical model with 3-operation Edit Distance (Levenshtein Distance) as a string matching metrics, termbase module, named entity recognition and transliteration are employed to enhance the quality and the efficiency of the translation. We further discussed the workflow among the processes involved in the establishment of our system and concluded with the efficient experimental results obtained.
Family Resemblance, Platonism, Universals

Platonic universals received sympathetic attention at the turn of the century in the early writings of Moore and Russell. But this interest quickly waned with the empiricist and nominalist movements of the twenties and thirties. In this process of declining interest Wittgenstein's theory of family resemblance seemed to serve both as coup de grâce and post-mortem. I propose, however, that family resemblance far from being an adequate refutation of Platonic universals can actually be accommodated within a Platonic theory properly conceived. But first for some caveats and qualifications. What family resemblance actually succeeds in refuting is not Platonic universals but Aristotelian or empiricist, or, generally, abstractive or commutative, universals. An abstractive universal is a universal arrived at by induction from identical characteristics in numerically distinct individuals (thus, for instance, see Aristotle's Metaphysics 5.26, 1023b30-31). An abstractive universal is a common property and nothing else. This conception of a universal has several consequences. First, abstractive universals are ontologically dependent on particulars.
Human Brain signal Analysis: Juvenile Myoclonic Epilepsy Diagnosis by Electroencephalograph

Juvenile Myoclonic Epilepsy recognition and its cognitive effect were investigated through Welch Periodogram analysis of EEG signals. The micro-volt brain delicate signals were measured by our laboratory KL-720 system with Kl-75004 Electroencephalogram module, after careful adjustments. The digital signal processing DSP proved itself through the MATLAB software as useful analyzing tool for the absolute and relative power extracted from EEG power spectrum in different frequency bands. It was the standard method by which Juvenile Myoclonic Epilepsy detected in primarily stage where effective treatment is available. It also indicated that the Juvenile Myoclonic Epilepsy have not any effect on brain cognitive function.

HSCCC Separation of the Two Iridoid Glycosides and Three Phenolic Compounds from Veronica ciliata and Their in Vitro Antioxidant and Anti-Hepatocarcinoma Activities

Five main compounds, including two iridoid glycosides (catalposide, verproside) and three phenolic compounds (luteolin, 4-hydroxy benzoic acid, 3,4-dihydroxy benzoic acid), were separated and prepared from the crude extract of Veronica ciliata by high-speed countercurrent chromatography. n-Hexane/n-butanol/water (1.5:5:5, v/v/v) was used for the separation of catalposide and verproside. n-Hexane/n-butanol/water (3:2:5, v/v/v) was used for the separation of luteolin, 4-hydroxy benzoic acid and 3,4-dihydroxy benzoic acid. The head-to-tail elution mode was used with a flow rate of 5.0 mL/min and a rotary speed of 800 rpm. Finally, a total of 1.28 mg luteolin, 6 mg 4-hydroxy benzoic acid, 2 mg 3,4-dihydroxy benzoic acid, 2 mg verproside and 10 mg catalposide with purities of 98%, 99.1%, 99.5%, 99.8% and 99%, respectively, were obtained from 200 mg of crude extract. In addition, their structure was identified using MS, 1H-NMR and 13C-NMR. To the best of our knowledge, this is the first report of the separation and purification of iridoid glycosides and phenolic compounds from V. ciliata by high-speed countercurrent chromatography (HSCCC). Among these compounds, luteolin, 4-hydroxy benzoic acid and 3,4-dihydroxy benzoic acid were separated from V. ciliata Fisch. for the first time. The results of the antioxidant activity show that protocatechuic acid and luteolin have strong antioxidant activity compared to 2,6-di-tert-butyl-4-methylphenol (BHT) and vitamin C (Vc). Five compounds also exhibited strong anti-hepatocarcinoma activities.
Microstructure analysis of AC corona aging of silicone rubber

A needle-plane electrode system was used to study the characteristics of the silicone rubber under AC corona. Microstructure and chemical structure change analysis on the surface of silicone rubber after corona ageing was made by using SEM, AFM and FTIR. Infrared spectrum shows that corona would cause the rupture of fundamental chain and branched chain of material. Along with the increase of corona aging time, the content of fundamental chain and branched chain will decrease. The continuous increase in the content of carbanyl group shows the intensifying oxidation. Hydroxyl -OH turns into combined condition from dissociative condition.
High‐resolution sodium dodecyl sulfate‐polyacrylamide gel electrophoresis and immunochemical identification of the 2X and embryonic myosin heavy chains in complex mixtures of isomyosins

In mammals myosin heavy chains (MHC) are polypeptides with a molecular mass of about 200 kDa whose isoforms can be identified by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS‐PAGE) and immunochemistry. Electrophoretic analysis is the only method for quantitating MHC profiles in single myofibers and/or cryostat sections of biopsied muscle. We present a method for SDS‐PAGE of adult rat skeletal muscle which resolves MHC into four bands: 1, 2B, 2X, and 2A from the faster to the slower migrating band. Furthermore, embryonic MHC can be also resolved in a complex mixture of isomyosins, e.g. developing or regenerating muscles. The method does not involve preparation of gradient gels or electrophoresis at low temperature. Improved reproducibility is obtained by: (i) modification of the sample buffer; (ii) use of 7% polyacrylamide in the separating gel; (iii) control of pH of running buffer by recirculation or change of the buffer during the run; and (iv) a 24 h run. The procedure is compatible with Coomassie Brilliant Blue, silver and immunoblot staining. Resolution is sufficient to permit transblotting of separated MHC after SDS‐PAGE. The different isoforms are easily identified with monoclonal antibodies. The technique provides an improved method to separate MHC and quantitate MHC2X and MHCemb in complex mixtures of MHC from a few cryostat sections of normal and diseased muscle.
Androgens: New Effects on Proteoglycan Biosynthesis and Its Consequences for Atherosclerosis

The pro- and antiatherogenic role of sex hormones is very controversial. These hormones have metabolic actions, but may also display actions directly on cells of the vasculature involved in atherosclerosis. We recently examined the effect of the male sex hormones, the androgens, on proteoglycan biosynthesis and LDL binding and found that androgens have a growth factor-like effect to increase the size of proteoglycans and enhance LDL binding. These studies demonstrate, at least in this in vitro model, that androgens can be proatherogenic.
Tadalafil in the treatment of lower urinary tract symptoms and erectile dysfunction

In the aging male, erectile dysfunction (ED) and lower urinary tract symptoms (LUTS) are common conditions that have been shown to be related. As life expectancy increases, treatments that target both ED and LUTS will prove increasingly valuable over the coming years. Phosphodiesterase type 5 (PDE5) inhibitors are used primarily to treat ED. Recently, studies have shown that improvements in LUTS are also seen with PDE5 inhibitor treatment. In particular, the PDE5 inhibitor tadalafil may be beneficial owing to its unique long-acting pharmacokinetic properties. We review the current literature to provide an insight into how tadalafil could provide symptomatic relief from ED and LUTS.
Salient object detection on multiscale learning and sparse coding

In this paper, we introduce a saliency detection method to automatically detect salient regions of different kinds of images with different complex scenes. Our method takes the advantages of efficiency and robustness of machine learning and sparse coding. We adopt concept of multiscale learning to use random forests classifier to get the training model. Then we construct non-saliency dictionary through the potential background information of initial map produced by using the training model. To refine the saliency map and achieve better saliency performance, we utilize weighted sparse coding to compute the saliency map with the non-saliency dictionary which contains the most foreground information. The experiment results indicate that our method is intuitive, effective and achieves state-of-the-art results on several benchmarks.
Modélisation physique et compacte de transistors en couches minces à base de silicium amorphe ou microcristallin

Dans le but de developper un modele compact specifique aux transistors en couches minces (TFT) a base de silicium amorphe ou microcristallin, nous presentons dans ce manuscrit nos etudes sur l'optimisation des modeles compacts et des methodes d'extraction des parametres et, surtout, differents phenomenes presents dans la physique de ces TFTs. Nous proposons une methode plus robuste d'extraction des parametres, qui, differemment des methodes conventionnelles, ne neglige pas la resistance d'acces, diminuant ainsi la subjectivite du procede de l'extraction. La resistance d'acces dans les differentes structures a ete analysee. Pour la structure top-gate coplanar, nous nous sommes focalises sur des raisons geometriques pour montrer la dependance de la resistance d'acces en tension de grille. Pour la structure bottom-gate staggered, nous avons introduit l'approche de transport-diffusion au modele de current crowding, en prouvant la dependance en tension de grille et en courant en raison de la diffusion des electrons. Le comportement dynamique a ete etudie en couplant mesures experimentales et simulations par elements finis, en associant les capacites intrinseques des TFTs avec le temps de retard d'allumage. Nous avons observe l'evolution temporelle du canal lors de sa creation ou de sa disparition et nous avons ainsi propose un modele qui decrit sa propagation dans un TFT. Nous avons enfin etudie le phenomene de vieillissement des TFTs et nous avons mis en evidence la localisation de la degradation et de la relaxation dans un TFT sous un stress electrique avec la tension de drain non-nulle.
Changes of Upper Thoracic Curve and Shoulder Balance in Thoracic Adolescent Idiopathic Scoliosis Treated by Anterior Selective Thoracic Fusion Using VATS

Study Design A retrospective radiographic analysis. Objectives To evaluate changes of upper thoracic curve and shoulder balance in thoracic adolescent idiopathic scoliosis patients treated by anterior selective thoracic fusion using video-assisted thoracoscopic surgery and to identify adequacy of earlier criteria of double thoracic (DT) curve for anterior correction. Summary of Background Data Although anterior and posterior scoliosis correction show many differences in correction mechanisms, fusion levels, loss of correction etc., the criteria of DT curve was applied without differences. There are no reports about these differences. Materials and Methods Forty patients were followed for a minimum of 3 years (range, 3-8 y). The magnitude and flexibility of upper thoracic, lower thoracic, and the superior portion of the lower thoracic curve were measured using full length standing and side-bending radiographs before surgery, at 1 week postoperatively, and at last follow-up. The correction rate and loss of correction of these curves were calculated and preoperative and postoperative radiographic shoulder heights (RSHs) were measured. RSH was defined as balanced (shoulder height difference <10 mm), mildly imbalanced (10-20 mm), or moderately imbalanced (>20 mm). T1 tilt and coronal balance were also evaluated. Patients were divided into groups based on these factors and postoperative RSH was compared. Results Flexibility of the upper thoracic curve was 46% and magnitude of the upper thoracic curve was corrected spontaneously from 28.6±7.8 degrees to 17.9±7.0 degrees with a 37.4% correction rate that did not change during follow-up. On average, preoperative left shoulder was 6.3±10.5 mm lower than right shoulder and this changed to 10.4±11.8 mm and 6.0±8.2 mm higher than right shoulder at 1 week postoperatively and at last follow-up, respectively. The group with an upper thoracic curve of ≥30 degrees or a superior portion of the lower thoracic curve of ≥30 degrees preoperatively had a higher left shoulder postoperatively (P=0.016, 0.040). Of the 12 patients with a symmetric or higher left shoulder (≥0 mm) preoperatively, 9 patients had a balanced shoulder (−10-10 mm) and 3 patients showed mild shoulder imbalance (<20 mm) at last follow-up. Conclusions Among patients who have DT curve, patients with mild left shoulder elevation (<20 mm) can be treated by anterior correction unless the magnitude of upper thoracic curve or superior portion of lower thoracic curve are ≥30 degrees. For anterior correction, criteria of DT curve might be applied less strictly.

Verbal learning and memory following stroke

Abstract Objective: The research examined whether verbal learning and memory impairment previously observed 1 year after left hemisphere stroke endures over a longer period and whether stroke sufferers compensate for their impairments using working memory. Methodology: Twenty-one persons with left hemisphere lesions; 20 with right hemisphere lesions only and 41 matched controls completed the Hopkins Verbal Learning Test-Revised (HVLT-R), a working memory test (Letter-Number Sequencing, LNS) and the Boston Naming Test (BNT). Results: Persons with left hemisphere damage performed more poorly on HVLT-R than controls. They showed poorer immediate recall, delayed recall, recognition and learning, but intact retention, suggesting an encoding impairment. BNT and LNS scores predicted recall in this group. HVLT-R performance of persons with right hemisphere lesions only was comparable to controls. BNT (not LNS) predicted recall in these groups. Conclusions: Persons with left hemisphere damage relied more on working memory and recruited diverse left hemisphere regions to compensate for their impaired encoding. Implications: Tasks requiring verbal encoding and memory are effortful following left hemisphere stroke. This should be recognized and accommodated.
Anisotrope Materialmodellierung für den menschlichen Unterkiefer

Im Rahmen der biomechanischen Simulation knocherner menschlicher Organe ist die Frage nach einer befriedigenden Materialbeschreibung nach wie vor ungelost. Computertomographische Datensatze liefern eine raumliche Verteilung der (Rontgen-) Dichte und ermoglichen damit eine gute Darstellung der individuellen Geometrie. Weiter konnen die verschiedenen Materialbestandteile des Knochens, Spongiosa und Kortikalis, voneinander getrennt werden. Aber die richtungsabhangige Information der Materialanisotropie ist verloren. In dieser Arbeit wird ein Ansatz fur eine anisotrope Materialbeschreibung vorgestellt, die es ermoglicht, den Einfluss der individuellen knochernen Struktur auf das makroskopische Materialverhalten abzuschatzen.
Novel CMOS voltage sensor with process invariant threshold for passive UHF RFID transponders

A novel process-invariant voltage sensor used in passive UHF RFID transponder has been presented in this work. The process-invariant characteristic is due to the deployment of an insensitive bandgap reference and its superb characteristics have been demonstrated. By adjusting the component values of the resistor divider, different threshold voltages can be defined. For demonstrating the superior performance of the proposed voltage sensor, its threshold voltage variations due to process corners and charging-up times have been illustrated and its low current consumption has also been shown.
