Effectiveness of a program of romana’s Pilates for non-specific low back pain: A pilot study
Objetivo: comprobar la efectividad del método Pilates Romana para conseguir
una mayor flexibilidad de la columna, junto con una mejora en la movilidad de la
misma, así como del dolor que presentan en su vida diaria los pacientes.
Metodología: ensayo clínico con intención de tratar a treinta pacientes con dolor
lumbar inespecífico. Asistieron a 15 sesiones, 2 veces a la semana, del Método
Pilates Romana.. Se evaluaron parámetros tales como dolor, test de Schöber,
SRS-22 y distancia dedos- suelo.
Resultados. Se encontraron diferencias estadísticamente significativas con
respecto al dolor (escala EVA), distancia dedos- suelo, test de Schöber
(flexibilidad en plano sagital), flexión lateral (flexibilidad en plano frontal) y en
varios ítems de la escala SRS-22, con valores de p<0,001. Por ello, este método
puede ser usado para mejorar el dolor, la flexibilidad axial, la función y los
aspectos relacionados con la calidad de vidaAim: to test the effectiveness of the Romana’s Pilates method to obtain
increased flexibility, improvements in mobility, and reduced pain in daily life.
Methodology: a clinical trial with intention-to-treat thirty patients with nonspecific
low back pain. Participants attended 15 sessions, twice a week. The
Romana’s Pilates method was taught by an external physiotherapist.
Parameters such as pain, the Schober test, and the SRS-22 were evaluated.
Results: Statistically significant differences in pain (VAS), the Schober test
(flexibility in sagittal plane), lateral flexion (flexibility in frontal plane) and several
items of the SRS-22 scale were found, with p <0.001.
This method may be used to improve pain, axial flexibility, function and aspects
related to the quality of life of patient
Analysis of the legume–rhizobia symbiosis in shrubs from central western Spain
s. rodríguez-echeverría, m.a. pérez-fernández, s. vlaar and t. finnan. 2003.Aims: This work analyses the diversity of rhizobia associated with some of the predominant shrubby legumes in central-western Spain. Symbiotic promiscuity and effectiveness were studied using cross-inoculation experiments with shrubby species.Material and Results: Six new bradyrhizobia strains were isolated from nodules collected from wild plants of six leguminous species, Cytisus balansae, C. multiflorus, C. scoparius, C. striatus, Genista hystrix and Retama sphaerocarpa. These isolates were genetically characterized by 16S rDNA partial sequencing and random amplification of polymorphic DNA2013PCR fingerprinting. The phylogenetic analysis revealed that these isolates could represent three new Bradyrhizobium species. Shrubby legumes and bradyrhizobia displayed a high symbiotic promiscuity both for infectivity and effectiveness. Symbioses were effective in more than 70% of the associations established by four of the six plant species.Conclusions: Native woody legumes in western Spain are nodulated by Bradyrhizobium strains. The high degree of symbiotic promiscuity and effectiveness highlights the complex dynamics of these communities in wild ecosystems under a Mediterranean-type climate. Furthermore, the results from this study suggest a potential importance of inoculation for these legume species in soil-restoration projects.Significance and Impact of the Study: This is the first study, to our knowledge, that combines both molecular analysis and pot trials to study the rhizobia2013legume symbiosis for wild legumes
TOY: A System for Experimenting with Cooperation of Constraint Domains
AbstractThis paper presents, from a user point-of-view, the mechanism of cooperation between constraint domains that is currently part of the system TOY, an implementation of a constraint functional logic programming scheme. This implementation follows a cooperative goal solving calculus based on lazy narrowing. It manages the invocation of solvers for each domain, and projection operations for converting constraints into mate domains via mediatorial constraints. We implemented the cooperation among Herbrand, real arithmetic (R), finite domain (FD) and set (S) domains. We provide two mediatorial constraints: The first one relates the numeric domains FD and R, and the second one relates FD and S

Quantum authentication with unitary coding sets
A general class of authentication schemes for arbitrary quantum messages is
proposed. The class is based on the use of sets of unitary quantum operations
in both transmission and reception, and on appending a quantum tag to the
quantum message used in transmission. The previous secret between partners
required for any authentication is a classical key. We obtain the minimal
requirements on the unitary operations that lead to a probability of failure of
the scheme less than one. This failure may be caused by someone performing a
unitary operation on the message in the channel between the communicating
partners, or by a potential forger impersonating the transmitter.Comment: RevTeX4, 10 page
Gangrena gaseosa: revisión de cuatro casos
Desde el mes de enero de 1988 hasta diciembre de 1993, hemos atendido en
el Servicio de Cirugía Ortopédica y Traumatología 6.853 pacientes, de ellos 263 presentaron
infecciones post-quirúrgicas, post-traumáticas o expontáneas. Del total de infecciones cuatro se
manifestaron como un cuadro clínico de gangrena gaseosa. El origen fue post-traumático en
tres casos y por arma de fuego en uno, localizándose la enfermedad en todos los pacientes en
las extremidades inferiores. Para establecer el diagnóstico además de las manifestaciones clínicas
se ha valorado el resultado bacterológico y anatomo-patológico de las muestras analizadas.
El tratamiento consistió en Cirugía precoz, antibioticoterapia y oxigenoterapia hiperbárica
cuando era necesario. La evolución ha sido buena en dos casos y desfavorable en el resto de
los enfermos.From January 1988 to December 1993, we have seen in our institution 6853
patients, 263 of them presented post-surgical, post-traumatic or spontaneus infections. Of the
total of infections, four of them were manifested as clinical cases of gaseous gangrene. The origin
was post-traumatic in three cases, and gun shot in one case, localizing the disease in all patients
in inferior extremities. For diagnosis clinical manifestations and the bacteriological and
patologic results were evaluated. The treatment consisted of early surgery, antibiotical therapy
and hiperbaric oxigenotherapy when it was necessary. The outcome was satisfactory in two cases
and non favorable in the other two patients
Crystallisation of amorphous Al-Y-Ni-(Cu)alloys
The nanocrystallisation behaviour and subsequent intermetallics formation
of an amorphous Al88-Y4-Ni8 alloy has been studied. A 1 at% of Al or Ni
was also substituted by Cu and its effect studied. Differential scanning
calorimetry has been used to measure the thermal stability of these
amorphous alloys. Transmission electron microscopy showed the smaller
size of the nanocrystals obtained during primary crystallisation when Cu is
added. Using three-dimensional atom probe, it has been checked that Cu is
homogeneously distributed in the amorphous matrix, not contributing to a
heterogeneous nucleation around Cu clusters during the formation of
nanocrystals. Transmission electron microscopy and X-rays diffraction are
used to study the controversial intermetallics occurrence at higher
temperatures. The sequence and characteristics of the intermetallics
appearing in these alloys were sensitive to the presence of Cu. The evolution
of these intermetallics, up to 600 ºC, has been studied. Findings are
compared with previous studies.Ministerio de Economía y Competitividad DPI2015-69550-C2-2-
Spin splitting in a polarized quasi-two-dimensional exciton gas
We have observed a large spin splitting between "spin" and
heavy-hole excitons, having unbalanced populations, in undoped GaAs/AlAs
quantum wells in the absence of any external magnetic field. Time-resolved
photoluminescence spectroscopy, under excitation with circularly polarized
light, reveals that, for high excitonic density and short times after the
pulsed excitation, the emission from majority excitons lies above that of
minority ones. The amount of the splitting, which can be as large as 50% of the
binding energy, increases with excitonic density and presents a time evolution
closely connected with the degree of polarization of the luminescence. Our
results are interpreted on the light of a recently developed model, which shows
that, while intra-excitonic exchange interaction is responsible for the spin
relaxation processes, exciton-exciton interaction produces a breaking of the
spin degeneracy in two-dimensional semiconductors.Comment: Revtex, four pages; four figures, postscript file Accepted for
