description: Using Large Binocular Telescope deep imaging data from the Smallest Scale of Hierarchy Survey (SSH) and archival Hubble Space Telescope data, we reveal the presence of two elongated stellar features contiguous to a bar-like stellar structure in the inner regions of the dwarf irregular galaxy NGC 3741. These structures are dominated by stars younger than a few hundred Myr and collectively are about twice as extended as the old stellar component. These properties are very unusual for dwarf galaxies in the nearby Universe and difficult to explain by hydro-dynamical simulations. From the analysis of archival 21-cm observations, we find that the young stellar "bar" coincides with an HI high-density region proposed by previous studies to be a purely gaseous bar; we furthermore confirm radial motions of a few km/s, compatible with an inflow/outflow, and derive a steeply-rising rotation curve and high HI surface density at the center, indicating a very concentrated mass distribution. We propose that the peculiar properties of the stellar and gaseous components of NGC 3741 may be explained by a recent merger or ongoing gas accretion from the intergalactic medium, which caused gas inflows towards the galaxy center and triggered star formation a few hundred Myr ago. This event may explain the young and extended stellar features, the bar-like structure, the very extended HI disc and the central HI spiral arms. The high central HI density and the steeply rising rotation curve suggest that NGC 3741 may be the progenitor or the descendant of a starburst dwarf.

Natural Hazard Mitigation in Urban Planning: A Canadian Case Study
Creators: name: Grochowich, Amanda
Publisher: name: The University of British Columbia
Year: 2013

description: With a changing climate and more frequent extreme weather events, natural hazards can have significant consequences and impacts on a local community. If a local government hasn’t properly prepared for a natural hazard’s impact, then the damage and devastation to a community can be quite severe. A natural hazard or disaster can have serious social, economic and environmental effects on a region. With the advent of the community and disaster planning profession, many local governments have been researching and implementing hazard related land use planning techniques. However, more recently community planners and disaster planners have been working more collaboratively, and have begun to integrate their two professions. Local communities interested in keeping their residents and assets safe and secure in the face of natural hazard risks often face challenges in properly communicating appropriate and adequate information highlighted by their community and disaster planners to their constituents and local stakeholders. Local governments and decison-makers have become accustomed to disseminating information to the public and have begun to adapt this strategy to the area of natural hazard planning. Of course, important considerations include, what are the best ways to communicate natural hazard planning? And, how available and accessible is natural hazard planning information to a local community? To answer these questions, the District of Maple Ridge, a community in the Metro Vancouver region of B.C. has been selected for a natural hazard planning and communication analysis. By starting with a community’s Official Community Plan (OCP), the research is hoping to highlight the areas and types of natural hazards which are not being properly communicated to residents. If residents are missing important aspects of hazard related information, the community will not be as resilient and secure in the face of a natural disaster.
An elementary and direct computation of cohomology with and without a group action

description: Recently, we introduced a configuration space with interaction structure and a uniform local cohomology on it with co-authors in arXiv:2009.04699. The notion is used to understand a common structure of infinite product spaces appeared in the proof of Varadhan's non-gradient method. For this, the cohomology of the configuration space with a group action is the main target to study, but the cohomology is easily obtained from that of the configuration space without a group action by applying a well-known property on the group cohomology. In fact, the analysis of the cohomology of the configuration space without a group action is the essential part of arXiv:2009.04699. In this article, we give an elementary and direct proof to obtain the cohomology of a space with a group action from that without a group action under a certain condition including the setting of the configuration space with interaction structure. In particular, no knowledge of group cohomology is required.

description: The temporomandibular joint (TMJ) connects the mandible to the skull. TMJ disorders induce degenerative tissue changes in TMJ disc that are largely the result of maladaption to abnormal joint loading. Histopathological studies have documented an association between TMJ arthropathy and loss of tissue cellularity, via apoptosis-related processes, that result in diminished extracellular matrix generation, organization, and repair. However, the exact molecular mechanisms underpinning the development and progression of such degenerative changes are still unclear. We review the most recent findings regarding the involvement of apoptotic mechanisms in TMJ disc degeneration. Although a number of aspects of TMJ disc degeneration have been thoroughly investigated, data on the involvement of apoptotic mechanisms and their mediators are few and quite recent; indeed most of the research conducted on fibrous cartilage apoptosis has focused on the intervertebral disc.

A General Relativistic Magnetohydrodynamic Model of High Frequency Quasi-periodic Oscillations in Black Hole Low-Mass X-ray Binaries

description: We suggest a possible explanation for the high frequency quasi-periodic oscillations (QPOs) in black hole low mass X-ray binaries. By solving the perturbation general relativistic magnetohydrodynamic equations, we find two stable modes of the Alfven wave in the the accretion disks with toroidal magnetic fields. We suggest that these two modes may lead to the double high frequency QPOs if they are produced in the transition region between the inner advection dominated accretion flow and the outer thin disk. This model naturally accounts for the 3 : 2 relation for the upper and lower frequencies of the QPOs, and the relation between the black hole mass and QPO frequency.

description: Variations in the branching pattern of the axillary artery have paramount importance among anatomists, surgeons and radiologists. A study was conducted on this topic in Kolkata, among the people of West Bengal, a state of India. The upper limbs of 70 cadavers were dissected bilaterally at the Department of Anatomy, Calcutta National Medical College, Kolkata, between 2008 and 2011. Among the study population, 52 cadavers (74.3%) were male and the rest were female, with average age 62.01 years (standard deviation = 6.58) and average height 1.59 meter (standard deviation = 0.096) respectively. The mean length of the axillary artery was 10.15 cm (standard deviation = 1.056). The superior thoracic, thoracoacromial and subscapular arteries were found to be constant branches of the axillary artery while the other branches showed considerable variations. Among those constant branches a high, significant correlation was found between the distance of origin of thoracoacromial artery from the outer border of the 1st rib and the length of the axillary artery, for the right and respectively the left upper limb of male cadavers. In females it showed a moderate, albeit significant correlation only. Similarly, the length of the axillary artery established a moderate correlation with the distance of origin of the superior thoracic and of the subscapular arteries on the right side of female cadavers. No other significant correlation was obtained.

El viaje y adiós a la poesía en Roberto Bolaño.pdf
Creators: name: Sánchez Ramos, Nelida Jeanette
Publisher: name: figshare

Subjects: Literature

description: En Roberto Bolaño el viaje está ligado a la palabra exilio en sus diferentes etapas de la vida, y se refleja en sus obras. El tema del viaje es una urbanidad que sólo parece coexistir dentro de una textualidad que la hace posible y sus protagonistas actúan como elementos centrípetos del relato. Efigies discontinuas que viven en una fuga permanente y en su mayoría son nómadas, exiliados de las dictaduras latinoamericanas, luchadores revolucionarios, poetas y novelistas fracasados. La poesía se abre a la narrativa, porque según Bolaño narrativa y poesía se reducen a una sola. En esta etapa la obra del escritor chileno se mezcla, se reduce a narrador lírico oa novelista poético, pero a la vez perfila la ciudad literaria cuyo contenido se precisa para informarnos sobre el siglo XXI.

description: Current cosmological models indicate that the Milky Way's stellar halo was assembled from many smaller systems. Based on the apparent absence of the most metal-poor stars in present-day dwarf galaxies, recent studies claimed that the true Galactic building blocks must have been vastly different from the surviving dwarfs. The discovery of an extremely iron-poor star (S1020549) in the Sculptor dwarf galaxy based on a medium-resolution spectrum cast some doubt on this conclusion. However, verification of the iron-deficiency and measurements of additional elements, such as the alpha-element Mg, are mandatory for demonstrating that the same type of stars produced the metals found in dwarf galaxies and the Galactic halo. Only then can dwarf galaxy stars be conclusively linked to early stellar halo assembly. Here we report high-resolution spectroscopic abundances for 11 elements in S1020549, confirming the iron abundance of less than 1/4000th that of the Sun, and showing that the overall abundance pattern mirrors that seen in low-metallicity halo stars, including the alpha-elements. Such chemical similarity indicates that the systems destroyed to form the halo billions of years ago were not fundamentally different from the progenitors of present-day dwarfs, and suggests that the early chemical enrichment of all galaxies may be nearly identical.

description: Questo articolo inaugura la sezione della nuova rivista SISM dedicata al progetto THESA. Il progetto THESA (THEatre Science Anatomy), come spiegato nella Presentazione di Lu-ca Borghi, mira alla catalogazione, riscoperta e, ove possibi-le, rivalutazione dei teatri anatomici storici, sorti in Italia e in Europa tra il Medioevo e la prima metà del Novecento. Ad ogni singolo teatro sarà dedicato un articolo, in cui verranno analizzate la sua storia, struttura e caratteristiche stilistiche, nonché i personaggi che hanno lavorato al suo interno e le tradizioni che regolavano l’anatomia pubblica. Questo primo articolo è dedicato a Bologna. La presentazione dei teatri anatomici di questa città è divisa in più parti, dato che in set-te secoli di pratica anatomica si sono alternate diverse co-struzioni. In questa prima parte, l’attenzione viene posta sul teatro anatomico dell’Archiginnasio, la prima sede ufficiale dell’Università felsinea. Il monumento, tuttora visitabile, è descritto nei dettagli, inoltre precede una ricostruzione delle fasi della sua realizzazione e dei suoi restauri. Sono riportate le usanze sociali e rituali che regolavano la pubblica funzione di anatomia, tenutasi durante il periodo di Carnevale dalla fine del Cinquecento all’inizio dell’Ottocento. L’articolo mira inoltre a fornire una bibliografia esaustiva dei maggiori studi che riguardano questo spazio, presentando nuove im-magini prodotte dal fotografo Rolando Paolo Guerzoni e una raccolta di immagini storiche.

description: Tra le principali malattie parassitarie che interessano il cane e colpiscono l’uomo ci sono quelle trasmesse da elminti, in particolare cestodi. La contaminazione ambientale e la mancata applicazione di semplici norme igieniche ne amplificano la trasmissione. L’echinococcosi (endemica in America Latina, Africa sub-Sahariana, Mongolia, Repubblica Popolare Cinese, Asia del sud e sud Est e Australia, e in tutte le regioni, dove, come in Sardegna, è fiorente la pastorizia) è considerata oggi come la zoonosi più importante della Regione Mediterranea. L’anchilostomiasi, patologia causata da un nematode, un tempo considerata patologia esclusiva di minatori, fornaciari, lavoratori della terra, è una parassitosi presente per lo più in aree del mondo dove la scarsità di adeguati presidi igienici e il clima caldo umido ne facilitano la diffusione; l’uomo malato trasmette con le feci le uova del parassita nell’ambiente, diventando contagioso per i propri simili. Mentre l’anchilostomiasi è ormai limitata ad aree del mondo depresse e a un’area circoscritta del territorio nazionale, l’echinococcosi pur in calo, è ancora presente in modo significativo soprattutto in Sardegna, nonostante le campagne di prevenzione e le innumerevoli risorse stanziate, economiche e umane. In questo lavoro si esamina l’utilizzo dei filmati prodotti e diffusi per informazione e prevenzione da ENPI, INAIL e Università degli Studi di Cagliari nella seconda metà del Novecento, alla luce di due inchieste territoriali condotte da Università di Cagliari e Istituto Zooprofilattico Sperimentale della Sardegna.

description: In male mouse, chromosome dynamics and recombination are tightly regulated by a pachynema checkpoint that arrest meiotic progression of recombination defective spermatocytes, which are than eliminated by stage IV of the epithelial cell cycle. In addition, male mouse meiocytes cell death is also activated by the failure of meiotic sex chromosome inactivation (MSCI). In the latter case, the apoptotic arrest is driven by the lack of silencing of XY-linked genes. In most of meiotic recombination mutants studied, so far, have been shown that in presence of a grossly aberrant synapses, also XY gene silencing fail. Thus both a defective chromosome dynamic and impaired MSCI contributes to spermatocytes elimination. Among several mutants H2Ax-/- spermatocytes are considered to be a model for apoptotic elimination exclusively driven by MSCI failure; such that no defects have been reported in chromosome dynamic and recombination. In this study we demonstrate that a fraction (~ 30%) of H2Ax-/- spermatocytes are defective in proper chromosome pairing, indicating that MSCI failure is not the only cause for their elimination by stage IV. In agreement with this finding, we find that the absence of H2Ax impair the proper localization, onto chromatin, of DNA repair factors, such as MDC1, BRCA1, MSH4 and MLH3. Interestingly, the defects in chromosome synapses and MLH3 foci assembly are ameliorated by Spo11 heterozygosis. Overall these results demonstrate that, in meiotic cells, H2Ax is require for the efficient processing of Spo11-induced double strand breaks.

description: Nel 1527 in Italia, a seguito dell’invasione dei lanziche-necchi comandati da Georg von Frundsberg parte dell’esercito che Carlo V inviò in Italia per sottomettere gli Stati italiani aderenti alla Lega di Cognac- comparve la peste bubbonica. A Bologna dal 1527 viene praticata dai fedeli una proces-sione dal Santuario della Madonna del Soccorso che at-traversa la città fino alla Chiesa di san Rocco. Il motivo di osservanza è colle-gato alla peste. Dopo il riscontro di al-cuni casi di peste nel rio-ne del Borgo di S. Pietro, la tra-dizione riporta che avvenne, grazie all’intervento della Madonna, il miracolo dell’interru-zione dell’epidemia. In seguito, a distanza di diversi decenni, alcuni autori bo-logne-si, non testimoni dei fatti, riportarono che il flagello aveva col-pito 12.000 persone su di una popolazione all’epoca prossima a 60.000 abitanti. Noi abbiamo rivalu-tato la questione a partire dai dati che i demografi hanno ottenuto, relativi alla popolazio-ne bolognese del XV, XVI e XVII secolo; inoltre abbiamo ri-cercato presso l’Archivio di Stato di Bologna se vi erano tracce di bandi e grida emessi in particolare nel 1527, dalle autorità.

description: It is well known that non-ideal magnetohydrodynamic effects are important in the dynamics of molecular clouds: both ambipolar diffusion and possibly the Hall effect have been identified as significant. We present the results of a suite of simulations with a resolution of 512-cubed of turbulent decay in molecular clouds incorporating a simplified form of both ambipolar diffusion and the Hall effect simultaneously. The initial velocity field in the turbulence is varied from being super-Alfvénic and hypersonic, through to trans-Alfvénic but still supersonic. We find that ambipolar diffusion increases the rate of decay of the turbulence increasing the decay from $t^{-1.25}$ to $t^{-1.4}$. The Hall effect has virtually no impact in this regard. The power spectra of density, velocity and the magnetic field are all affected by the non-ideal terms, being steepened significantly when compared with ideal MHD turbulence with exponents. The density power spectra components change from about 1.4 to about 2.1 for the ideal and non-ideal simulations respectively, and power spectra of the other variables all show similar modifications when non-ideal effects are considered. Again, the dominant source of these changes is ambipolar diffusion rather than the Hall effect. There is also a decoupling between the velocity field and the magnetic field at short length scales. The Hall effect leads to enhanced magnetic reconnection, and hence less power, at short length scales. The dependence of the velocity dispersion on the characteristic length scale is studied and found not to be power-law in nature.

description: We report on the photodissociation dynamics study of n-butyl nitrite (n-C_4H_9ONO) and isoamyl nitrite ((CH_3)_2C_3H_5ONO) by means of time-resolved Fourier transform infrared (TR-FTIR) emission spectroscopy. The obtained TR-FTIR emission spectra of the nascent NO fragments produced in the 355-nm laser photolysis of the two alkyl nitrite species showed an almost identical rotational temperature and vibrational distributions of NO. In addition, a close resemblance between the two species was also found in the measured temporal profiles of the IR emission of NO and the recorded UV absorption spectra. The experimental results are consistent with our ab initio calculations using the time-dependent density functional theory at the B3LYP/6-311G(d,p) level, which indicate that the substitution of one of the two {gamma}-H atoms in n-C_4H_9ONO with a methyl group to form (CH_3)_2C_3H_5ONO has only a minor effect on the photodissociation dynamics of the two molecules.

description: Endothelial injury is the primary event that leads to a variety of severe vascular disorders. The signal transduction pathway which drives the subsequent healing process is far from being fully elucidated. Mechanical injury elicits a Ca2+ response in the endothelium of intact rat aorta, which comprises an initial Ca2+ release from inositol-1,4,5-trisphosphate-sensitive (IP3Rs) stores followed by a long-lasting decay phase due to Ca2+ entry through uncoupled connexons. In a minor fraction of cells, the Ca2+ signal adopts an oscillatory pattern whose molecular underpinnings are yet to be elucidated. In the light of the role played by repetitive Ca2+ spikes in regulating tissue regeneration, the present study aims at elucidating the mechanisms underlying injury-induced Ca2+ oscillations. The repetitive Ca2+ signal reversibly ceased upon removal of extracellular Ca2+ or addition of the inorganic cations, La3+ and Ni2+. Moreover, the spiking response was abolished by the gap-junction blockers, heptanol and 18 beta-glycyrrhetinic acid and by interfering with the Ca2+ entry-mode mode of the Na+/Ca2+ exchanger (NCX). The InsP3-producing agonist, ATP, resumed Ca2+ oscillations in silent cells, while the phospholipase C inhibitor, U73122, inhibited the oscillatory signal. The latter was also prevented by the SERCA inhibitors, thapsigargin and cyclopiazonic acid acid. These data show that injury-induced [Ca2+]i oscillations require the coordinated interplay between NCX-mediated Ca2+ entry and InsP3-dependent Ca2+ release. Besides directly gating Ca2+ inflow, uncoupled connexons might let Na+ into the cells and stimulate Ca2+ entry through NCX by increasing submembranal Na+ levels.

description: Adipose tissue expansion involves the enlargement of existing adipocytes, the differentiation of adipocyte progenitors, and the development of the supporting vascular network. Although some data suggest that the adipocyte progenitors reside in the vasculature of the adipose tissue, their identity is not completely clear [1,2]. Here we address the hypothesis that a population of adipocytes derives from an endothelial cell (EC) lineage. We performed a detailed morphological analysis in developing murine WAT and BAT in order to highlight the features of adipocyte precursors. In addition, we used the VE-Cadherin- Cre/R26R mouse model to address the relationship between vascular ECs and adipose cells development. This lineage tracing model allowed the identification of cells that express the EC gene VE-Cadherin at any point during differentiation. Finally, we analyzed capillary sprouts arising from human subcutaneous fat tissue to evaluate the hypothesis that ECs forming these structures possess the capacity to transform into adipocytes. Ultrastructural analysis of discrete areas of intense adipogenesis, that we designated vasculo-adipocytic islets, revealed the presence of rare endothelial-pericytic cells that could represent an intermediate developmental step between the EC and the preadipocyte stage. Lineage tracing experiments using the VE-cadherin promoter revealed the expression of reporter genes in ECs, preadipocytes and adipocytes in white and brown fat depots. Furthermore, capillary sprouts (which have predominantly EC characteristics) from human adipose tissue were found to express Zfp423, a recently identified marker of preadipocyte determination [3]. In response to PPARγ activation the ECs lost progressively their structural and molecular characteristics, and formed structurally and biochemically defined adipocytes. We report morphological and genetic evidence that adipocytes in white and brown fat depots originate from cells that display endothelial characteristics and this is in accordance with the results published by other researchers [4] and also with previous works performed in our lab [5].

description: It is becoming increasingly clear that tumour development is due to a small fraction of mutated stem cells (CSC). Established cancer cell lines represent a good source of CSC with respect to tissue tumour samples because they do not contain any contaminating normal stem cells and it is easy to obtain large quantities of them. We isolated putative CSC via a non-adherent neurosphere (NS) assay from LI. Using a clonal assay, we selected from the primary NS two clones named F11 and D2. LI, F11 and D2 cells and these clones under differentiation were examined for expression of stem cell markers (CD133, Nestin, Musashi-1 and Sox-2), markers of differentiation (βIII-Tubulin and GFAP) and Ca2+-channels, by immunocytochemistry, western blot analysis and confocal Ca2+ imaging. Both F11 and D2 clones expressed higher levels of stem cell markers with respect to LI cells. Markers of differentiation were expressed at high levels in both LI cells and clones. The expression of Nestin, Sox-2, and βIII-Tubulin was down-regulated in clones under differentiation, whereas Musashi-1 was increased. LI, F11 and D2 cells did not exhibit Ca2+ signals following KCl-induced membrane depolarization, thus suggesting that they do not express functional voltage-dependent Ca2+-channels. Nevertheless, transient increases in intracellular Ca2+ levels were observed after cell exposure to ATP in both F11 and D2 during differentiation. The ATP treatment did not affect cell proliferation. The increased expression of stem cell markers and their decrease in cells under differentiation demonstrate the stem characteristics of clones we selected. The findings regarding expression of differentiation markers and of Ca2+-channels require further investigation. After a deeper characterization, both F11 and D2 could represent a good model to improve the knowledge on CSC and to identify new therapeutic approaches in GBM.

description: Depending on the stellar densities, protoplanetary discs in stellar clusters undergo background heating, disc truncation-driven by stellar encounter, and photo-evaporation. Disc truncation leads to reduced characteristic sizes and disc masses that eventually halts gas giant planet formation. We investigate how disc truncation impacts planet formation via pebble-based core accretion paradigm, where pebble sizes were derived from the full grain-size distribution within the disc lifetimes. We make the best-case assumption of one embryo and one stellar encounter per disc. Using planet population syntheses techniques, we find that disc truncation shifts the disc mass distributions to the lower margins. This consequently lowered the gas giant occurrence rates. Despite the reduced gas giant formation rates in clustered discs, the encounter models mostly show as in the isolated field; the cold Jupiters are more frequent than the hot Jupiters, consistent with observation. Moreover, the ratio of hot to cold Jupiters depend on the periastron distribution of the perturbers with linear distribution in periastron ratio showing enhanced hot to cold Jupiters ratio in comparison to the remaining models. Our results are valid in the best-case scenario corresponding to our assumptions of: only one disc encounter with a perturber, ambient background heating and less rampant photo-evaporation. It is not known exactly of how much gas giant planet formation would be affected should disc encounter, background heating and photo-evaporation act in a concert. Thus, our study will hopefully serve as motivation for quantitative investigations of the detailed impact of stellar cluster environments on planet formations.

description: We demonstrate that magnetic reconnection is not necessary to initiate fast CMEs. The Aly-Sturrock conjecture states that the magnetic energy of a given force free boundary field is maximized when the field is open. This is problematic for CME initiation because it leaves little or no magnetic energy to drive the eruption, unless reconnection is present to allow some of the field to escape without opening. Thus, it has been thought that reconnection must be present to initiate CMEs. This theory has not been subject to rigorous numerical testing because conventional MHD numerical models contain numerical diffusion, which introduces uncontrolled numerical reconnection. We use a quasi-Lagrangian simulation technique to run the first controlled experiments of CME initiation in the complete lack of reconnection. We find that a flux rope confined by an arcade, when twisted beyond a critical amount, can escape to an open state, allowing some of the surrounding arcade to shrink and releasing magnetic energy from the global field. This mechanism includes a true ideal MHD instability. We conclude that reconnection is not a necessary trigger for fast CME eruptions.

description: Periodontal diseases, the major public health problem of the oral cavity, are clinically characterized by inflammation of the periodontal connective tissue that ultimately induces the destruction of periodontal tissue and the loss of alveolar bone. In chronic periodontitis, as well as aggressive periodontitis, the anaerobic gram-negative bacterium Porphyromonas gingivalis (P. gingivalis) is implicated, and its pathogenicity is exerted by a wide variety of factors, among which the lipopolysaccharides (LPSs). LPSs activate the innate immune response during Gram-negative bacterial infections through the Toll-like receptor 4 (TLR-4)/myeloid differentiation protein 2 (MD- 2) complex. In this study, the expression of TLR-4, the cell growth, the cytokines release and the nuclear factor-KB (NF-kB) transcription factor expression in response to LPS-P. Gingivalis (LPS-G) were examined in Human Periodontal Ligament Mesenchymal Stem Cells (PDL-MSCs) [1]. The results obtained have demonstrated that, in basal conditions, human PDLMSCs express high levels of TLR-4. In inflammatory conditions mimicked by LPS-G challenge, the MTT assay carried out at different treatment times evidenced the decrease of the cell growth. Moreover, the recognition of P. gingivalis components by TLR-4 culminated with the activation of secretion of inflammatory mediators such as: IL-6, IL-8 and CCL-20, and with the up-regulation of NF-kB, which was translocated into the nucleus. Our data intended to specify that TLR-4 expressed by PDL-MSCs is functional and plays a key role in inflammation.

description: Introduction PAD medical therapy has a number of limitations. RLX showed promises in experimental model mainly through NO release. Our study is the first to evaluate the efficacy and safety of RLX in PAD. Materials-Methods eligible PAD La fontaine IIa-IIb patients were randomized in 2 groups. Group A was treated with physical therapy plus oral pRLX, 20 ug b.i.d for 12 weeks, group B received physical therapy alone. Pain Free Walking Distance (PFWD) and Maximum Walking Distance (MWD) at 3 and 12 wks and at follow up 3 months after treatment interruption were performed. Results The percentage increases of PFWD in group B were 23±9, 65±17, and 35±4 respectively at 3 and at 12 weeks. and 3 months after termination. In Group A showed significantly higher percentage increases: 74±16 p<0.01, 168±28 p<0.001, and 122±15 p<0.001 at the corresponding time points. The percentage increases of MWD in the B group were 29±7, 55±10 and 54±8 at the above time points, while in the A group were 55±10 p<0.001, and 99±12 p<0.001. The RLX patients referred a better physical and mental status. No adverse events during or after the treatment were recorded. Comment-RLX resulted very effective in PAD. Our results may suggest that the observed functional benefits should come not only from hemodynamic improvement but also from positive vascular remodeling.
