Objective: To date, serum free testosterone measurement is considered to be the gold standard for the diagnosis of hypogonadism in elderly males but it is not available to all subjects suspected of a decrease in testicular function. Therefore, we evaluated whether the Androgen Deficiency in Aging Males (ADAM) questionnaire, in its original or in a modified 'quantitative' version (qADAM), could be used as a surrogate to biochemical determinations for the identification of hypogonadism in elderly males. Methods: 5028 men, aged 50-70 years, spontaneously consulting for the assessment of their gonadal function were studied. ADAM and qADAM, allocating a value of 1 point for any positive answer to each of the 10 questions of the ADAM test, were assessed for their ability to discriminate between males with free testosterone levels below or above 70 ng/l. Results: The sensitivity and specificity of the ADAM score were 81% and 21.6% respectively. The use of ADAM resulted in an appropriate classification of our population in normal or hypogonadal subjects in 44.5% of the cases. The area under the receiver operating characteristics (ROC) curve for the qADAM (0.529) revealed a highly marginal interest of this quantitative approach compared with the original scoring system. Conclusions: The ADAM test has a high sensitivity to identify aging males with low free testosterone levels. However, due to its lack of specificity, this test cannot be used as a surrogate to serum free testosterone testing for the identification of androgen deficiency in elderly, community-dwelling males.

Electronic nose is a promising technique for field monitoring of malodours in the environment. It is based on an array of non-specific gas sensors coupled with some form of mathematical data processing method to analyse the global response patterns. Some applications concerning the control of water quality are reported in the literature. They often impliy the generation of a headspace gas above liquid samples, but they also concern the odour emitted in the air from wastewater. The typical needs of the final user require both qualitative and quantitative approaches, i.e. both discriminating between slight variations in complex gas mixtures and monitoring a global odour signal which can be correlated with classical characterisation variables of water or air quality. Although potential applications in odour assessment by electronic noses are numerous, a number of challenges still need to be overcome: understanding and controlling the impact of environmental parameters (such as temperature and humidity), improving sensor sensitivity and noise reduction or developing calibration procedures to account for sensor drift. The present limitations of electronic nose technology restrict its use in the environment to the odour monitoring in the surroundings of the emission with instruments specifically designed for the application.

Rapeseed oil (RO) (a choice source of unsaturation-rich residues) was used in the present study to enrich anhydrous milk fat (AMF) with unsaturated C18 fatty acids (FA) (oleic, linoleic and linolenic acids). Comparatively, one “harder” fraction of AMF underwent the same reaction. The physico-chemical properties modifications induced by the reaction were followed. The compositional changes are reported in this first part and the consequent physical modifications are presented in a second part. [less ▲]

Chemical and/or physical modification of oils and fats are commonly used by food industry to widen their range of applications (1,2). Lipase-catalysed interesterification of anhydrous milk fat (AMF) and various vegetable oils is now a well documented procedure (3-7). The purpose of this technique is to produce original structured fats with properties different from a simple blending, that may be used as spreads or introduced into pastry. The new fats contain higher amounts of polyunsaturated fatty acids (PUFA) than butter, which provides health benefits (8,9). To our knowledge only a few authors associated AMF fractionation with blending and interesterification (10,11), although this combination may be used to increase the ratio of vegetable oil in blends and thus the PUFA content of the product. The compositional changes occurring during the lipase-catalysed interesterification of AMF/rapeseed oil (RO) and AMF stearin fraction (AMFSF)/RO blends were described in the first part of this study. In the present and second part are reported the resulting changes in physical properties, especially the melting behaviour through solid fat content (SFC), dropping point (DP) and fusion profiles by differential scanning calorimetry (DSC).

This paper focuses on the numerical modeling of nanoindentation tests. The first goal of this study is to collect essential material parameters and boundary conditions from the literature and to complete the data required to accurately model nanoindentation tests. The second goal of this study consists in validating the material parameters identified from macroscopic tensile tests of the body-centered cubic b phase of Ti-5553, a new generation of titanium alloy. This validation is performed looking at experimental and numerical nanoindentation curves obtained for different grain orientations. [less ▲]

In this report, pregnancies were obtained after extreme in vitro conditions- IVM/F/C of the donor embryos, - IVM, enucleation and artificial activation of the recipient oocytes, - nuclear transfer and - IVC of the reconstituted embryos. Even if the incidence of this syndrome is relatively low after embryo transfer, a possible increasing of its occurence cannot be excluded in correlation with an incomplete maturation of oocytes at the time of fertilization, smaller follicles giving non competent or partially competent oocytes. An other explanation of this syndrome resulting in the higher variation in newborn calves weight may be also partly explained by the in vitro conditions. The gametes and/or embryos may be submitted to media containing embryotoxic substances. In the other hand, gametes and/or embryos may not found embryotrophic substances in the media like growth factors... Owing to this phenomenon, strict recommendations should be followed concerning rigorous follow-up of pregnancies obtained after transfer of IVM/IVF/IVC or cloned embryos by pregnancy proteins (PSPB, PAG...) or hormone (placental lactogen, estrone sulfate) assay and, after birth, macroscopic examinations of newborn, cord and caroncules.
