One Dimensional Magnetized TG Gas Properties in an External Magnetic Field
With Girardeau's Fermi-Bose mapping, we have constructed the eigenstates of a
TG gas in an external magnetic field. When the number of bosons is
commensurate with the number of potential cycles , the probability of this
TG gas in the ground state is bigger than the TG gas raised by Girardeau in
1960. Through the comparison of properties between this TG gas and Fermi gas,
we find that the following issues are always of the same: their average value
of particle's coordinate and potential energy, system's total momentum,
single-particle density and the pair distribution function. But the reduced
single-particle matrices and their momentum distributions between them are
different.Comment: 6 pages, 4 figure
Time-domain THz spectroscopy reveals coupled protein-hydration dielectric response in solutions of native and fibrils of human lyso-zyme
Here we reveal details of the interaction between human lysozyme proteins,
both native and fibrils, and their water environment by intense terahertz time
domain spectroscopy. With the aid of a rigorous dielectric model, we determine
the amplitude and phase of the oscillating dipole induced by the THz field in
the volume containing the protein and its hydration water. At low
concentrations, the amplitude of this induced dipolar response decreases with
increasing concentration. Beyond a certain threshold, marking the onset of the
interactions between the extended hydration shells, the amplitude remains fixed
but the phase of the induced dipolar response, which is initially in phase with
the applied THz field, begins to change. The changes observed in the THz
response reveal protein-protein interactions me-diated by extended hydration
layers, which may control fibril formation and may have an important role in
chemical recognition phenomena
EFFECTS OF BALANCING HAMSTRING AND QUADRICEPS MUSCLE TORQUE ON RUNNING TECHNIQUE
It has been suggested that balancing the isokinetic strength of quadriceps (Q) and hamstring (H) muscles can reduce hamstring injuries during running (Croisier et al 2008). The efficacy of this type of intervention has been previously explored. To further the knowledge of the H: Q relationship we have examined the intervention’s affect on running technique as presented here
Altered movement patterns but not muscle recruitment in moderately trained triathletes during running after cycling
Previous studies have shown that cycling can directly influence neuromuscular control during subsequent running in some highly trained triathletes, despite these triathletes\u27 years of practice of the cycle-run transition. The aim of this study was to determine whether cycling has the same direct influence on neuromuscular control during running in moderately trained triathletes. Fifteen moderately trained triathletes participated. Kinematics of the pelvis and lower limbs and recruitment of 11 leg and thigh muscles were compared between a control run (no prior exercise) and a 30 min run that was preceded by a 15 min cycle (transition run). Muscle recruitment was different between control and transition runs in only one of 15 triathletes (<7%). Changes in joint position (mean difference of 3°) were evident in five triathletes, which persisted beyond 5 min of running in one triathlete. Our findings suggest that some moderately trained triathletes have difficulty reproducing their pre-cycling movement patterns for running initially after cycling, but cycling appears to have little influence on running muscle recruitment in moderately trained triathletes. <br /
Adherence, satisfaction and preferences for treatment in patients with psoriasis in the European Union: a systematic review of the literature
Background and objective: Adherence to treatment in patients with psoriasis is often poor.
An investigation of patient preferences and satisfaction with treatment may be important, based
on the expected correlation with therapy compliance. This paper aims to examine and describe
the current literature on patient preferences, satisfaction and adherence to treatment for psoriasis
in the European Union (EU).
Methods: Electronic searches were conducted using PubMed, ISI Web of Knowledge, Scopus,
Spanish databases and Google Scholar. European studies published in English or Spanish
between January 1, 2009 and December 31, 2014 regarding patient-reported outcomes in
psoriatic patients were included. Studies conducted in non-EU countries, letters to the editor,
editorials, experts’ opinions, case studies, congress proceedings, publications that did not differentiate
between patients with psoriasis and psoriatic arthritis or studies related to specific
treatment were excluded.
Results: A total of 1,769 titles were identified, of which 1,636 were excluded as they were
duplicates or did not provide any relevant information. After a full-text reading and application
of the inclusion/exclusion criteria, 46 publications were included. This paper will describe publications
on adherence (n=4), preferences (n=5) and satisfaction with treatment (n=7). Results
related to health-related quality of life articles (n=30) have been published elsewhere. Adherence
rates are generally low in psoriasis patients regardless of the type of treatment, severity
of disease or methods used to measure adherence. Biologic therapy is associated with greater
clinical improvement. There is a direct association between physician recommendations, patient
preferences and several domains of treatment satisfaction.
Conclusion: The results of this review support the conclusion that adherence rates in patients
with psoriasis are suboptimal and highlight the need to improve patient compliance and satisfaction
with treatment. Patients’ preferences should be taken into account in the treatment
decision-making process in order to improve patients’ clinical outcomes by ensuring satisfaction
and adherence
