The Deep Impact target comet 9P/Tempel 1 was observed by means of long-slit spectroscopy from two nights before impact up to eight nights after impact, using the ESO VLT UT1, UT2, and ESO NTT telescopes. Spectra covering the complete optical wavelength range were obtained, and information at different position angles in the coma was collected. The data were used to study the gas and dust activity of comet 9P/Tempel 1. Gas production rates before and after impact and the amount of material in the impact cloud were determined. The pre-impact Afρ parameter, the dust production rate and the dust-to-gas mass ratio were derived. A variation of the cometary gas activity with rotation of the nucleus was detected. A difference in the variation of the brightness of the CN gas emission band compared to the variation of the emissions by C_2, C_3, and NH_2 in the inner coma suggests compositional differences between different parts of the surface of comet 9P/Tempel 1's nucleus.

An important policy instrument for governments to modify travel behavior and manage the increasing travel demand is the introduction of a congestion pricing system. In this study, the influence of a detailed classification of activities is examined to assess likely traveler response to congestion pricing scenarios. Despite the fact that most studies do not differentiate between activity categories, the value of time and in general the space–time properties and constraints of different types of activities vary widely. For this reason, it is of importance to provide sufficient detail and sensitivity in assessing the impact of congestion pricing scenarios. In addition, a first assessment of travelers’ possible multifaceted adaptation patterns is presented. For these purposes, a stated adaptation study was conducted in Flanders, the Dutch-speaking region of Belgium. The experiment was conducted through an interactive stated adaptation survey. In the stated adaptation experiment, respondents could indicate their responses to the congestion pricing scenario. The most prevalent conclusion is that the activity type significantly predetermines the willingness to express a more environment-friendly behavior (i.e., reducing the number of trips, reducing the total distance traveled, switching to more environment-friendly modes). Also, the willingness to show ecological activity-travel behavior (e.g., carpooling and using public transport) in a nonpricing situation is a major differentiator of future behavior in a congestion pricing scenario.

Complex regional pain syndrome (CRPS) remains difficult to understand and to treat. The definition criteria of the IASP (International Association for the Study of Pain) in 1994 showed an overestimation of diagnosis. A revision of these criteria conducted in Budapest in 2003 permits to ameliorate the specificity of these criteria in clinical and research settings. Pathophysiology is poorly understood, only one mechanism can’t explain the observed manifestations in the CRPS: facilitated neurogenic inflammation, peripheral and central abnormalities of the central nervous system … Finally, the different laboratory tests are reviewed. Unfortunately, no laboratory test is the signature of CRPS. The diagnosis relies on history and rigorous clinical examination. Imagery method, neurophysiologic test and evaluation of inflammatory parameters help to the differential diagnosis. [less ▲]

Sex change in the protandrous fish Amphiprion akallopisos Bleeker, 1853 (F.Pomacentridae) has been analysed. Experiments consisted of placing males together after being separated from their mates, and observe changes in gonad histology at different periods, in order to identify signs of the sex change process. The presence of a first invagination on the male gonad wall, and the observation of the first cortical alveoli oocytes as an indication of the beginning of the vitellogenesis process, was the first symptom of the sex change, which has been detected after 18 days in one of the males. Period needed for the sex changing process was size independent. The process by which wall invagination is converted into ovarian lumen in the future mature ovary is also described. [less ▲]

The clinical diagnosis of cutaneous melanoma always calls for histological confirmation. In addition to the recognition of the classic aspects of the neoplasm, immunohistochemistry is determinant, in particular in the assessment of the size of the replicative compartment. Generally, the proliferation rate is indicative of the neoplastic progression and is related to the clinical growth rate of the neoplasm. It allows to distinguish high risk melanomas showing a high growth rate from those of lower malignancy associated with a restricted growth rate. In melanoma, the recruitment and progression of neoplastic cells in the cell cycle of proliferation have lost some of their controls that are normally processed by a series of key regulatory molecules. In addition, the apoptotic pathway counteracting any hyperproliferative activity is released of the dependency of specific regulated molecular mechanisms. This review summarizes the current knowledge on key molecular components involved in the deregulation of the growth fraction, cell proliferation and apoptosis in melanocytic neoplasms. The implication of cyclins and of the mitogen-activated protein kinase pathways are scrutinized. The involvement of neoplastic stem cells in the metastatic process is also discussed. [less ▲]

Enteric infections caused by Salmonella remain a major public health burden worldwide. Poultry, particularly chickens, are known to be the main reservoir for this zoonotic pathogen. Therefore, the prevention and monitoring of Salmonella infection during the live phase may greatly reduce the contamination of poultry meat during slaughter and processing. With the ban on sub-therapeutic antibiotic usage in Europe and the increasingly strictness of the European legislation on food hygiene, passive immunization by oral administration of pathogen-specific hen egg yolk antibody (IgY) may be a useful and attractive alternative. This review offers summarized information about IgY production and the use of these antibodies for passive immunization, particularly in poultry [less ▲]

Establishing the osteoarticular status of the horse is often performed by means of radiological screening of the animals. Widespread blood sampling could reveal to be an interesting alternative to this procedure which is time consuming and sometimes technically difficult. The aim of this study was to investigate the relationship between the radiological status of the horses and the levels of biochemical markers of cartilage degradation and synovial inflammation. A specific radiological scoring and classification system was therefore developed and applied on 63 stallions presented for studbook admission. Additionally, groups of horses were established according to the occurrence of osteochondrosis, degenerative joint disease and distal interphalangeal joint effusion. Insulin growth factor-I, myeloperoxidases, Coll2-1 and Coll2-1NO(2) were used as blood markers. The combination of the blood parameters did not seem to correlate with the used scoring system. Coll2-1NO(2) levels however tended to increase with poorer radiological class and this could therefore potentially be a useful predictor of the osteoarticular status in the horse. Coll2-1 levels were significantly higher in the degenerative joint disease group. A high percentage of horses with distal interphalangeal joint effusion was present in this study and was associated with decreased IGF-I and increased Coll2-1 levels. [less ▲]

Le travail féminin a bien entendu ses particularités. Mais nos sociétés sont-elles attentives à leurs implications ? Et les pratiques d’aujourd’hui témoignent-elles de changements significatifs sur leplan d’un « plus » d’égalité entre femmes et hommes ? Que révèlent les situations, les évolutions et les tendances actuelles ? Ces questions sont rencontrées par Annie Cornet. Il se trouve que l’approche attentive au « genre » - the gender - est déterminante pour donner à voir et à comprendre les évolutions en cours. Le « genre » et les stéréotypes culturels, de type sexiste, interviennent dans une multiplicité de domaines qui influencent l’emploi au féminin. [less ▲]

Ferrets are carnivorous animals very close to the polecats. They are used in many <br />fields and are currently used widespread as pets. Their anatomy and physiology allow classifying them as carnivorous predators. Their diet consists of small prey. Studies on the nutritional requirements are very scarce and based mostly on comparisons with the cat or mink. The longevity factor is consistently absent from these studies although many diseases have a nutritional origin. Their digestive tract is not much differentiated and the transit is very quick, the digestion is inefficient. Their energy requirements are extremely high, much more than the cat. Ferrets require a high intake of animal protein —not from plant— of high nutritional quality and energyprotein ratio adjusted. Lipids are the main source of energy in the diet, and must be present in significant amounts. The minimum requirements are dependent on fatty acid composition, fat should be of animal origin and mostly of good quality. The ferret eating only animal products, there is no demonstrated requirements of carbohydrates. In addition carbohydrates are involved in different diseases. Micronutrient needs have been little studied and are often based on observation of deficiencies. Domestic ferrets are prone to diseases of nutritional origin; this leads many experts to rethink the diet of this animal. [less ▲]
