    Objective: to report on prostatic biopsy results in Algerian patients presenting with a suspicious Digital Rectal Examination (DRE) and\or an elevated total PSA.Methods: data collected on prepared index cards were age, result of DRE, rate of PSA and number of cores, as well as the histological result. The biopsies were performed by two urologist surgeons from Oran city, Algeria.Results: 331 patients had prostatic transrectal ultrasound-guided biopsies, the average (SD) age was 70.4 (8.7) years with a range 33 - 94 years. The most important age bracket was the one with subjects over 60 years. The DRE was suspicious in 41.69% of patients (138 of 331), and 44.20% of the suspect prostates on DRE were malignant. The average PSA was 42.2 ng/ml the rate of PSA >10 ng/ml constituted 72.57%. The number of biopsy cores was 12 for 129 biopsies, 49.2% of the biopsies revealed prostatic adenocarcinoma. The percentage of positive biopsies was 41.66% (21/48) when the PSA was between 4 and 10 ng/ml, and 33.33% (45/135) when the PSA exceeded 10 ng/ml. Among 47 scores of Gleason 59.7% patients had a score 7, 8.6% had a score < 7, and 31.8% had scores >7.Conclusion: 49.2% of 331 biopsies were positive for prostatic adenocarcinoma. Significant associations were found between age and cancer, between digital rectal examination and prostate biopsy results, and between PSA and number of positive cores

    The high oxidative stability of virgin olive oil is related to its high monounsaturated/polyunsaturated ratio and to the presence of antioxidant compounds, such as tocopherols and phenols. In this paper, the isolation of phenolic compounds from virgin olive oil from several Algerian varieties was tested and discussed in order to know its potential uses and benefits. Quantification of phenolic and o-diphenolic substances was performed using the traditional Folin-Ciocalteau method and the sodium molybdate reaction, respectively. The qualitative and quantitative characterizations of phenolic compounds were carried out by HPLC. The experimental results show that tyrosol, hydroxytyrosol and 4-HBA (4-hydroxybenzoic acid) are the main individual phenolic compounds identified in the varieties studied. The varieties with large fruits (Grosse du Hamma, Aghenfas, Azeradj, Aguenaou, Aberkane, Bouchouk de Guergour, X-Aghenfas, Rougette de Guelma, Sigoise) are clearly distinguished from the varieties with medium-sized and small fruits by having the highest levels of individual phenolic compounds. Moreover, varieties with small fruits (Hamra, Chemlal, Boughenfas, Limli, Aimel and Mekki) presented the highest levels of oleuropein.La alta estabilidad oxidativa de los aceites de oliva vírgenes está relacionada con su alta relación de ácidos grasos monoinsaturados/poliinsaturados y con la presencia de componentes antioxidantes, como tocoferoles y polifenoles. En este trabajo se llevó acabo un aislamiento y cuantificación de compuestos fenólicos de aceites de oliva virgenes de variedades argelinas, con el fin de conocer sus potenciales usos y beneficios. La cuantificación de los componentes fenólicos y o-difenólicos se realizó por método tradicional de Folin-Ciocalteu y mediante la reacción con molibdato de sodio, respectivamente. Los compuestos fenólicos individuales cualitativos y cuantitativos en los extractos y en una mezcla estándar fueron determinados por HPLC. Los resultados experimentales muestran que el tirosol, hidroxitirosol y el 4-HBA (ácido 4-hidroxibenzoico) son los principales compuestos fenólicos individuales identificados en el conjunto de la población de las variedades estudiadas. Por otra parte, la población de las variedades con frutos grandes (Grosse du Hamma, Aghenfas, Azeradj, Aguenaou, Aberkane, Bouchouk de Guergour, X-Aghenfas, Rougette de Guelma, Sigoise) se distinguen claramente de las variedades con frutos medios y pequeños. Además, la población de variedades con frutos pequeños (Hamra, Chemlal, Boughenfas, Limli, Aimel y Mekki) presentó el nivel más alto en oleuropeína

    Background: Whether the measurement of cortisol in dairy cows can be used as a biomarker of adverse environmental or pathophysiological conditions is still under of scientific debate. In these situations, several systems mainly the hypothalamic-pituitary-adrenal axis, the autonomic nervous system, and the immune system are recruited to reestablish homeostasis. A first aim of the present study was to compare milk and blood cortisol concentrations and to consider its variability in milk in relation to farm, milk yield and days in milk. A second study investigates the effects of breed, class of somatic cell count (SCC) and farm on milk cortisol levels in a larger number of cows and farms, with the aim to validate the results obtained in the pilot study. Methods: For study 1, 135 cows were sampled from 2 Italian Simmental and 2 Italian Holstein commercial farms, whilst in the second study, 542 cows were sampled from 6 commercial farms of Italian Simmental and 499 cows from 4 commercial farms of Italian Holstein. Results: In study 1, the values of cortisol content in milk were significantly higher in Holstein than Simmental cows. Significant differences between farms were observed for milk and plasma cortisol concentrations. Cortisol content in milk was not correlated to plasma content in study 1 and the mean milk to plasma cortisol ratio was about 1:30. In study 2, for Holstein cows, significantly higher values of milk cortisol in comparison to Simmental cows was reported. A significant effect of class of SCC was observed, cows belonging to class 3 (SCC higher than 400.000/ml) showed the highest mean values of milk cortisol. The farm effect was significant also in the study 2, confirming the results obtained in the first study. Conclusions: Milk can be considered a preferential site of sampling in dairy cows to point out short term stimulation of the hypothalamic-pituitary-adrenal axis. Further studies are needed to investigate the physiological basis of the relationship between milk cortisol content and bree

    In this study, the authors tested four cultural models—independence, interdependence, conflict, and integration—that describe the hypothesized relationships between dimensions of self-construal and components of subjective well-being among individualistic and collectivistic countries. Collectivistic countries that have undergone rapid socioeconomic changes (i.e., East Asian countries) and those with limited changes (i.e., African countries) were differentiated. Participants were 791 university students from four Western countries, 749 university students from three East Asian countries, and 443 university students from three African countries. Findings provided some support for the applicability of (a) the independence model to individuals from Western countries and (b) the integration model to individuals from East Asian countries. Mixed results were found among the African countries. The interdependence model is more applicable to African participants from the sub-Saharan region, but the integration model is more applicable to those from the North African region
