Radiative lifetimes of nine odd levels in Hf III (5d6p z3P0,1, z1D2, z3D1,2,3, z3F2,3,4) and of two odd levels in Hf I (5d6s26p z3D2,3) have been determined using Time-Resolved Laser-Induced Fluorescence ... [more ▼]

Radiative lifetimes of nine odd levels in Hf III (5d6p z3P0,1, z1D2, z3D1,2,3, z3F2,3,4) and of two odd levels in Hf I (5d6s26p z3D2,3) have been determined using Time-Resolved Laser-Induced Fluorescence. The investigated levels in Hf I were excited in a single-step process from the ground term (5d26s2 a3F), whereas in Hf III we started from either the ground term 5d2 a3F or the low-lying 5d6s a3D term. For all of the investigated levels, the lifetimes have been measured for the first time. A multiconfiguration relativistic Hartree–Fock method, including core-polarization effects, has been used to compute radiative lifetimes of 15 Hf III levels, including those measured in this work. Transition probabilities for 55 transitions in Hf III are also given. [less ▲]

OBJECTIVE: To assess the long-term effects of chondroitins 4 and 6 sulfate (CS) on the radiographic progression of, and symptom changes associated with, knee osteoarthritis (OA). METHODS: We performed an international, randomized, double-blind, placebo-controlled trial in which 622 patients with knee OA were randomly assigned to receive either 800 mg CS (n = 309 patients) or placebo (n = 313 patients) once daily for 2 years. Radiographs of the target knee, using the Lyon schuss view, were obtained at the time of enrollment and at 12, 18, and 24 months. The minimum joint space width (JSW) of the medial compartment of the tibiofemoral joint was assessed by digital image analysis. The primary outcome was the loss in minimum JSW over 2 years. RESULTS: The intent-to-treat analysis demonstrated a significant reduction (P < 0.0001) in minimum JSW loss in the CS group (mean +/- SEM -0.07 +/- 0.03 mm) as compared with the placebo group (-0.31 +/- 0.04 mm). The percentage of patients with radiographic progression > or =0.25 mm was significantly reduced in the CS group compared with the placebo group (28% versus 41% [P < 0.0005]; relative risk reduction 33% [95% confidence interval 16-46%]). The number of patients needed to treat was 8 (95% confidence interval 5-17). Pain improved significantly faster in the CS group than in the placebo group (P < 0.01). There were no differences in safety between groups. CONCLUSION: The long-term combined structure-modifying and symptom-modifying effects of CS suggest that it could be a disease-modifying agent in patients with knee OA. [less ▲]

BACKGROUND: Persistent use of glucocorticoid drugs is associated with bone loss and increased fracture risk. Concurrent oral bisphosphonates increase bone mineral density and reduce frequency of vertebral fractures, but are associated with poor compliance and adherence. We aimed to assess whether one intravenous infusion of zoledronic acid was non-inferior to daily oral risedronate for prevention and treatment of glucocorticoid-induced osteoporosis. METHODS: This 1-year randomised, double-blind, double-dummy, non-inferiority study of 54 centres in 12 European countries, Australia, Hong Kong, Israel, and the USA, tested the effectiveness of 5 mg intravenous infusion of zoledronic acid versus 5 mg oral risedronate for prevention and treatment of glucocorticoid-induced osteoporosis. 833 patients were randomised 1:1 to receive zoledronic acid (n=416) or risedronate (n=417). Patients were stratified by sex, and allocated to prevention or treatment subgroups dependent on duration of glucocorticoid use immediately preceding the study. The treatment subgroup consisted of those treated for more than 3 months (272 patients on zoledronic acid and 273 on risedronate), and the prevention subgroup of those treated for less than 3 months (144 patients on each drug). 62 patients did not complete the study because of adverse events, withdrawal of consent, loss to follow-up, death, misrandomisation, or protocol deviation. The primary endpoint was percentage change from baseline in lumbar spine bone mineral density. Drug efficacy was assessed on a modified intention-to-treat basis and safety was assessed on an intention-to-treat basis. This trial is registered with ClinicalTrials.gov, number NCT00100620. FINDINGS: Zoledronic acid was non-inferior and superior to risedronate for increase of lumbar spine bone mineral density in both the treatment (least-squares mean 4.06% [SE 0.28] vs 2.71% [SE 0.28], mean difference 1.36% [95% CI 0.67-2.05], p=0.0001) and prevention (2.60% [0.45] vs 0.64% [0.46], 1.96% [1.04-2.88], p<0.0001) subgroups at 12 months. Adverse events were more frequent in patients given zoledronic acid than in those on risedronate, largely as a result of transient symptoms during the first 3 days after infusion. Serious adverse events were worsening rheumatoid arthritis for the treatment subgroup and pyrexia for the prevention subgroup. INTERPRETATION: A single 5 mg intravenous infusion of zoledronic acid is non-inferior, possibly more effective, and more acceptable to patients than is 5 mg of oral risedronate daily for prevention and treatment of bone loss that is associated with glucocorticoid use.

We propose a technique capable of imaging a distinct physical object with sub-Rayleigh resolution in an ordinary far-field imaging setup using single-photon sources and linear optical tools only. We exemplify our method for the case of a rectangular aperture and two or four single-photon emitters obtaining a resolution enhanced by a factor of 2 or 4, respectively. [less ▲]

Les pneumonies bactériennes constituent un problème majeur dans l'élevage et l'engraissement des bovins, avec des répercussions très élevées en termes de morbidité et de mortalité. Parmi les différentes causes biologiques recensées, Mannheimia haemolytica tient le haut de l’affiche puisqu’elle est connue comme agent pathogène compliquant principal, voire systématique. Une de ses particularités est qu’elle ne déclenche de pneumonie broncho-alvéolaire fibrino-hémorragique que chez les ruminants. Les lésions observées résultent d’une nécrose en masse des neutrophiles et macrophages et du relarguage de leurs différents constituants. Au niveau moléculaire, cette spécificité trouve son origine dans l’intimité de la liaison entre la leucotoxine, le facteur de virulence majeur de la bactérie, et la sous-unité CD18 des récepteurs de surface leucocytaires bêta2-intégrines. La revue décrit cette liaison et ses conséquences aux niveaux macroscopique et microscopique, avant de faire le point sur les dernières avancées de la recherche et d’ébaucher quelques perspectives thérapeutiques.

Artificial olfaction system (the so-called electronic nose) is a very promising tool to monitor the malodour in the field. Usual odour measurement techniques use human olfaction or analytical techniques. The first category represents the real odour perception but is not applicable to measure in continuous bad odours in the field. The second class of techniques gives the composition of the mixture but not the global information representative of the odour perception. The e-nose has the potentialities to combine “the odour perception” and the “monitoring in the field”. However to be able to reach this goal, the signal processing has to be adapted to work in complex environment. We have more than teen years experiments in the measure of environmental malodours in the field and the paper presents the minimal requirements that we consider essential for artificial olfaction system to become successful for this application.

Clinical affections of the locomotor and respiratory systems are the two main causes of poor performance in sport horses. Nevertheless, each subclinical affection of any system implicated in the oxygen system (respiratory, cardiovascular, blood, muscular and metabolic) may also become a limiting factor concerning the athletic capacities of the horse. A systematic medical examination of the horse, combining ail the clinical and laboratory exams, is thus necessary in order to establish a precise and comprehensive diagnosis regarding the different affections. The objectives of this communication are therefore to present the different methods currently available for the practitioner as well as the techniques recently developed for horses. The complementarity of the different clinical and laboratory exams, as well as the ideal moment for performing each test are clarified in order to accurately determine the different causes of poor performance as well as their functional repercussions [less ▲]

The complex {Fe[HC(3-Mepz)2(5-Mepz)]2}(BF4)2 (pz = pyrazolyl ring) has been prepared by the reaction of HC(3-Mepz)2(5-Mepz) with Fe(BF4)2·6H2O. The solid state structures obtained at 294 and 150 K show a distorted iron(II) octahedral N6 coordination environment with the largest deviations arising from the restrictions imposed by the chelate rings. At 294 K the complex is predominately high-spin with Fe–N bond distances averaging 2.14 Å, distances that are somewhat shorter than expected for a purely high-spin iron(II) complex because of the presence of an admixture of ca. 70 (I get 80 from both mag and X-ray, 3/15, where 3 is the subtraction of 2.14 and 2.17 and 15 1.99 and 2.14 and from Figure 3b) percent high-spin and 30 (20) percent low-spin iron(II). At 294 K the twisting of the pyrazolyl rings from the ideal C3v symmetry averages only 2.2o, a much smaller twist than has been observed previously in similar complexes. At 150 K the Fe–N bond distances average 1.99 Å, indicative of an almost fully low-spin iron(II) complex; the twist angle is only 1.3o, as expected for a complex with these Fe–N bond distances. The magnetic properties show that the complex undergoes a gradual change from low-spin iron(II) below 85 K to high-spin iron(II) at 400 K. The 4.2 to 60 K Mössbauer spectra correspond to a fully low-spin iron(II) complex but, upon further warming, the iron(II) begins to undergo spin-state relaxation on the Mössbauer time scale such that, at 155 and 315 K, the complex is 7.5 and 65 percent high-spin in the absence of any adjustment for the differing low-spin and high-spin recoil-free fractions. I would replace the previous sentence with the red. I see no reason to give the % from the Mössbauer in the abstract as it is likely a bit low as discussed in detail – neither the mag data nor X-ray data have the recoil issue. The last sentence in the abstract is the key information. OK The 4.2 to 60 K Mössbauer spectra correspond to a fully low-spin-iron(II) complex but, upon further warming above 85 K the iron(II) begins to undergo spin-state relaxation between the low- and high-spin forms on the Mössbauer time scale. At 155 and 315 K the complex exhibits spin-state relaxation rates of 0.36 and 7.38 MHz, respectively, and an Arrhenius plot of the logarithm of the relaxation rate yields an activation energy of 670 ± 40 cm–1 for the spin-state relaxation.

Besides the concentric classical ratios, the eccentric isokinetic assessment of the muscle shoulder allows us to build some specific ratios. The mixed ratio combines the eccentric maximal contraction of the external rotators (ER) and the concentric maximal strength of the internal rotators (IR). The mixed ratio is frequently decreased among overhead athletes. This imbalance could rise to shoulder tendinopathy, but seemed to be linked with field performance. The functional ratio corresponds to the balance between the ER in concentric mode and the IR in eccentric contraction. The unstable shoulder shows a trend to lower functional ratios, highlighting the weakness of the eccentric IR in that pathology. [less ▲]
