To distinguish species or populations using morphometric data is generally processed through multivariate analyses, in particular the discriminant analysis. We explored another approach based on the maximum likelihood method. Simple statistics based on the assumption of normal distribution at a single variable allows to compute the chance of observing a particular data （or sample） in a given reference group. When data are described by more than one variable, the maximum likelihood （MLi） approach allows to combine these chances to find the best fit for the data. Such approach assumes independence between variables. The assumptions of normal distribution of variables and independence between them are frequently not met in morphometrics, but improvements may be obtained after some mathematical transformations. Provided there is strict anatomical correspondence of variables between unknown and reference data, the MLi classification produces consistent classification. We explored this approach using various input data, and compared validated classification scores with the ones obtained after the Mahalanobis distance-based classification. The simplicity of the method, its fast computation, performance and versatility, make it an interesting complement to other classification techniques.

Twenty-two lactic acid bacteria （LAB） strains isolated from Argentinean goat dairy products were evaluated for its biochemical properties and esterase activities relevant to flavor development. Streptococcus thermophilus （UnSE314）, Lactobacillus （L.） delbrueckii subsp, bulgaricus （UnSE309）, L. rhamnosus （UnSE308）, L. plantarum （UnSE287, UnSE316, UnSE317） and Pediococcus pentosaceus （UnSE315） strains presented high acidifying activity. All strains tested metabolized citrate and produced diacetyl-acetoin in goat milk. Based on these results, 10 strains with the best performance in diverse technological properties were selected to determine esterolytic activity. In all evaluated strains, esterase specific activity （ESA） was detected on ct-naphthyl （ct-nA） acetate and 13-naphthyl （[3-nA） acetate, propionate, eaprylate and ct-nA butyrate. no activity was detected on [3-nA laurate. The highest values were detected when using a-nA instead of fI-nA derivatives as substrate. In Pediocoecus strains, wide variability in ESA were observed, which were species- and strain-specific. These results allow us to select strains with biochemical properties and esterase activities to design starter and adjunct cultures that contribute to flavor development during cheese ripening, thus preserving the typical organoleptic characteristics of Argentinean goat cheeses.

A grazing experiment was undertaken to assess the effects of two levels of herbage mass (HM) on herbage DM intake (DMI), fat and protein corrected milk yield (FPCM), grazing behaviour, energy expenditure (HP), and methane emissions (CH4) of grazing dairy cows in spring. Treatments were a low HM (1447 kg DM/ha;LHM) or a high HM (1859 kg DM/ha;HHM). Pasture was composed mainly of cocksfoot (n>Dactylis glomeratan>) and lucerne (n>Medicago sativa), offered at a daily herbage allowance of 30 kg DM/cow, above 5 cm. Eight multiparous Holstein cows were used in a 2 × 2 Latin Square design in two 10-day periods. Despite the differences in pre-grazing HM between treatments, OM digestibility was not different (P = 0.28). Herbage mass did not affect DMI or FPCM. Grazing time was not different between treatments, but cows had a greater bite rate when grazing on LHM swards. However, HP did not differ between treatments. Daily methane emission (per cow), methane emission intensity (per kg FPCM) and methane yield (as percentage of gross energy intake) were not different. The lack of effect of the amount of pre-grazing HM on energy intake, confirms that the difference between HM treatments wasn style="font-family:Verdana;"> beyond the limits that impose extra energy exp

Macadamia nuts (Macadamia integrifolia) grown in Venezuela have showed an average total fat content of 70%. Oleic acid (18:1) was the main monounsaturated fatty acid (MUFA) (51.3%), followed by palmitoleic acid (16:1, 22.6%). The content of polyunsaturated fatty acids (PUFAs), C18:2 and C18:3 represented 5.4%. Thus, MUFAs and PUFAs together constituted more than 80% of the total fatty acids present. Trans-vaccenic acid was also present (3%). As regards to other phytochemical compounds, tocopherols and tocotrienols were not found in the sample, but the presence of squalene was *** antioxidant activity (44.2%) of the extract was produced by the phytochemicals present.

Background: A number of strategies exist for the implementation of clinical practice guides (CPGs). Aim: To assess the efficacy of implementing a cardiovascular risk CPG based on an educational method involving opinion leaders, and the habitual method of dissemination among primary healthcare teams. Design and Setting: Controlled, blinded, community intervention trial randomised by clusters. Methods: 21 primary healthcare centres were randomly assigned to either the intervention arm (n = 11) or the control arm (n = 10). The study subjects were patients aged ≥45 years assigned to the centres. The overall impact of the intervention was measured as the difference between the increase in the proportion of patients whose medical records showed the recording of all the variables necessary to calculate cardiovascular risk in both arms. Analyses were performed with Generalized Lineal Model on an intention-to-treat basis. Results: 917 subjects were included at the beginning of the trial (437 in the intervention arm and 480 in the control arm). 826 subjects were included in the final evaluation (436 in the intervention group and 390 in the control arm). At the end of the trial, the recording of the variables necessary for the calculation of the cardiovascular risk in the intervention group had increased more than in the control group (difference between increases 7.49% (95% CI 4.62 - 10.35)) after adjusting for confounding variables. Conclusions: Compared to the habitual method of dissemination, the implementation of this CPG using an educational method involving opinion leaders, improved the recording of the variables needed to calculate patients’ cardiovascular risk.
