Osteoporosis is a systemic bone disease characterized by low bone mass and bone mineral density, and deterioration of the underlying structure of bone tissue. These changes lead to an increase in bone fragility and an increased risk for fracture, which are the clinical consequences of osteoporosis. The classical triad for consideration in osteoporosis is morbidity, mortality and cost. Vertebral fracture is an important source of morbidity in terms of pain and spinal deformity. On the other hand, hip fracture is associated with the worst outcomes and is widely regarded as a life-threatening event in the elderly; it is the source of the bulk of the cost of the disease in contemporary healthcare. The prevention of osteoporosis-associated fracture should include fall prevention, calcium supplementation and lifestyle advice, as well as pharmacological therapy using agents with proven antifracture efficacy. The most commonly used osteoporosis treatments in Europe are the bisphosphonates alendronate, risedronate, ibandronate and zoledronic acid; the selective estrogen receptor modulator (SERM) raloxifene; teriparatide; and strontium ranelate. Recent additions include the biological therapy denosumab and the SERM bazedoxifene. In this review, we explore the antifracture efficacy of these agents with the aim of simplifying treatment decisions. These treatments can be broadly divided according to their mode of action. The antiresorptive agents include the bisphosphonates, the SERMs and denosumab, while the bone-forming agents include parathyroid hormone and teriparatide. Strontium ranelate appears to combine both antiresorptive and anabolic activities. We collated data on vertebral and hip fracture efficacy from the pivotal 3-year phase III trials, all of which had a randomized, double-blind, placebo-controlled design. The relative reductions in risk in the osteoporosis trials range from 30% to 70% for vertebral fracture and 30% to 51% for hip fracture. This translates into 3-year number needed to treat values of between 9 and 21 for vertebral fracture and from 48 upwards for hip fracture. International guidelines agree that agents that have been shown to decrease vertebral, nonvertebral and hip fractures should be used preferentially over agents that only demonstrate vertebral antifracture efficacy. This is the case for alendronate, risedronate, zoledronic acid, denosumab and strontium ranelate. Finally, therapeutic decisions should be based on a balance between benefits and risks of treatment, which must be carefully considered in each particular case both by the physician and the patient. Indeed, no single agent is appropriate for all patients and, therefore, treatment decisions should be made on an individual basis, taking into account all measures of treatment effect and risk before making informed judgments about the best individual treatment option.

Long-lasting debates question whether faces are special stimuli treated preferentially by our visual system or whether prioritized processing of faces is simply due to increased salience of their constituting features. To examine this issue, we used a visual search task in which participants had to make a saccade to the circle with a unique color among a set of six circles. Critically, there was a task-irrelevant object located next to each circle. We examined how an upright face, an inverted face or a butterfly, presented near the target or non-target circles affected eye movements to the target. Upright (13.12%) and inverted faces (10.8%) located away from the target circle captured the eyes more than butterflies (8.5%), but upright faces captured the eyes more than inverted faces. Moreover, when faces were next to the target, upright faces, and to some extent inverted faces, facilitated the saccades towards the target. Faces are thus salient and capture attention. More importantly however above and beyond their raw salience based on low-level features, canonical upright faces capture attention stronger than inverted faces. Therefore, faces are ‘special’ and our visual system is tuned to their meaning and not only to low-level features making up a face. [less ▲]

In a porcine liver transplant model, a brief period of oxygenated hypothermic machine perfusion (HMP) at the end of simple cold storage (SCS) has been shown to improve the viability of damaged liver grafts. To test the clinical validity of this strategy, we randomized SCS-discarded human liver grafts to either 4 hours of HMP (n = 13) or an additional 4 hours of SCS (n = 14). All livers were then warm reperfused to mimic ischemia-reperfusion injury ex vivo. The settings for HMP were: portal vein: 3 mm Hg, 300 mL/min and hepatic artery: 20 mm Hg, po(2): 300 mm Hg. Perfusion used Kidney Machine Perfusion Solution at 4 degrees C to 8 degrees C. During warm reperfusion, aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) values were higher (P < .015) among the SCS versus HMP methods at all times. The AST slope was lower in HMP versus SCS (P = .01). The LDH slope tended to be lower for HMP versus SCS (P = .07). Morphological scores were not different between HMP and SCS. At the start of warm reperfusion, MAPK was lower in HMP versus SCS (P = .02). Endothelin-1 (EDN1) and ICAM-1 tended to be lower in HMP versus SCS (P = .1 and .07, respectively). No difference was noted in MAPK, EDN1, and ICAM-1 after 60 or 120 minutes of warm reperfusion. In conclusion, HMP down-regulated MAPK and tended to reduce EDN1 and ICAM-1 mRNA in human liver grafts. During warm reperfusion, HMP versus SCS livers showed reduced AST and LDH release but no morphological difference. Further optimization of liver HMP may require different timing/duration of perfusion and/or an higher perfusion temperature. [less ▲]

Le Cadre Européen Commun de Référence pour les Langues fait l'objet d'une description et d'une analyse critique. L'influence (in)directe du CECRL sur l'enseignement-apprentissage des langues partout en Europe est illustrée à travers plusieurs exemples et questionnée à la lumière du concept de développement d'une pensée didactique unique, laquelle présente le risque d'être inefficace et inéquitable.

It has been shown that during embryonic chicken (Gallus gallus) development, the metabolism of broiler embryos differs from that of layers in terms of embryonic growth, pCO2/pO2 blood levels, heat production, and heart rate. Therefore, these strains might adapt differently on extreme environmental factors such as exposure to high CO2. The aim of this study was to compare broiler and layer embryos in their adaptation to 4% CO2 from embryonic days (ED) 12 to 18. Due to hypercapnia, blood pCO2 increased in both strains. Blood bicarbonate concentration was ~10 mmol/L higher in embryos exposed to high CO2 of both strains, while the bicarbonates of broilers had ~5 mmol/L higher values than layer embryos. In addition, the pH increased when embryos of both strains were exposed to CO2. Moreover, under CO2 conditions, the blood potassium concentration increased in both strains significantly, reaching a plateau at ED14. At ED12, the layer strain had a higher increase in CAII protein in red blood cells due to incubation under high CO2 compared to the broiler strain, whereas at ED14, the broiler strain had the highest increase. In conclusion, the most striking observation was the similar mechanism of broiler and layer embryos to cope with high CO2 levels. [less ▲]

Photocatalytic degradation of organic and inorganic pollutants on the TiO2 semiconductor has been extensively studied as a way to solve environmental problems relating to wastewater and polluted air. Anatase and rutile are the most commonly used crystalline structures of TiO2, with anatase showing a higher photocatalytic activity attributed to its higher specific surface area and its favourable band gap energy (Eg). However, its high band gap (Eg = 3.2 eV) implies the use of UV light (lambda ≤ 380 nm) to inject electrons into the conduction band (TiO2(e-CB)) and to leave holes in the valence band (TiO2(h+VB)). Although the low band gap energy of rutile-TiO2 (Eg = 3.02 eV) allows rutile to potentially absorb more solar energy than anatase, the anatase-to-rutile phase transition leads to the collapse of the TiO2 specific surface area, which may result in a decrease in the photocatalytic activity of rutile. Low specific surface area and therefore poor absorption properties lead to strong limitations in exploring the photo-efficiency of rutile. Nevertheless, rutile has been proved to be comparable to anatase in its photoelectrochemical properties when used in dye-sensitized solar cells. In the present study, a new process for the reduction of rutile-TiO2 xerogel under hydrogen flow was developed to enhance the photocatalytic activity of TiO2 materials synthesized by the sol-gel process. So a series of H2-reduced TiO2 xerogels of low specific surface area was prepared by hydrolysis and condensation of tetraisopropoxy titanium(IV) in 2-methoxyethanol. The gels were dried under vacuum, calcined in air at different temperatures (400°C, 500°C and 700°C) and finally reduced in H2 at 400 °C. The materials were characterized by X-ray diffraction, transmission electron microscopy (TEM), FT-IR spectroscopy and UV/Visible diffuse reflectance spectroscopy. The texture was determined by nitrogen adsorption-desorption measurements. The effects of the calcination/reduction treatments on the adsorption of methylene blue (MB) in aqueous solution and on the photocatalytic degradation of MB and crystal violet (CV) under UV and visible light irradiation were also evaluated. Results showed predictable modifications in the physico-chemical properties caused by the annealing of TiO2 xerogel at high calcination temperature (700 °C), such as a total anatase-to-rutile phase transition and a considerable loss of specific surface area from 260 to 2 m2 g-1. However, the higher degree of reduction exhibited by the rutile-TiO2 lattice led to unpredictable photocatalytic activity for the dye conversion under UV and visible light irradiation: the loss of specific surface area of the rutile-TiO2 sample was compensated by the increase in the affinity of this sample for the dye. Under UV light irradiation, the rutile-TiO2 xerogel obtained after a calcination at 700 °C showed a similar level of photoactivity as the one obtained with anatase-TiO2 xerogels obtained by calcination at 400 °C and 500 °C. Under visible light, unlike anatase-TiO2 xerogels, the rutile-TiO2 xerogel showed a higher dye photoconversion rate per external surface area (40 times higher) than the commercial TiO2 Degussa P25.
