Efeito do peso do ovo e do seu tempo de armazenamento sobre a viabilidade dos pintos do dia

Este trabalho foi desenvolvido com o intuito de estudar o efeito do peso do ovo e do seu tempo de armazenamento sobre a viabilidade dos pintos do dia, resultantes de um bando de galinhas Shaver Redbro cruzadas com galos Starcross x Shaver carecos. Neste sentido, na cidade de Bragança (latitude 410 49'N, longitude 60 40'W e altitude 720 metros), mais precisamente na Quinta de Santa Apolónia, pertencente à Escola Superior Agrária de Bragança, foram efectuadas quatro séries de incubação utilizando no seu conjunto, 333 ovos sujeitos a um período de armazenamento que variou entre 2 e 34 dias (15,6+9,1 dias)

In vivo nutrigenomic effects of virgin olive oil polyphenols within the frame of the Mediterranean diet: a randomized controlled trial

12 páginas, 3 figuras, 5 tablas.-- et al.The aim of the study was to assess whether benefits associated with the traditional Mediterranean diet (TMD) and virgin olive oil (VOO) consumption could be mediated through changes in the expression of atherosclerosis-related genes. A randomized, parallel, controlled clinical trial in healthy volunteers (n=90) aged 20 to 50 yr was performed. Three-month intervention groups were as follows: 1) TMD with VOO (TMD+VOO), 2) TMD with washed virgin olive oil (TMD+WOO), and 3) control with participants’ habitual diet. WOO was similar to VOO, but with a lower polyphenol content (55 vs. 328 mg/kg, respectively). TMD consumption decreased plasma oxidative and inflammatory status and the gene expression related with both inflammation [INF-γ (INFγ), Rho GTPase-activating protein15 (ARHGAP15), and interleukin-7 receptor (IL7R)] and oxidative stress [adrenergic β2-receptor (ADRB2) and polymerase (DNA-directed) κ (POLK)] in peripheral blood mononuclear cells. All effects, with the exception of the decrease in POLK expression, were particularly observed when VOO, rich in polyphenols, was present in the TMD dietary pattern. Our results indicate a significant role of olive oil polyphenols in the down-regulation of proatherogenic genes in the context of a TMD. In addition, the benefits associated with a TMD and olive oil polyphenol consumption on cardiovascular risk can be mediated through nutrigenomic effects.—Konstantinidou, V., Covas, M.-I., Muñοz-Aguayo, D., Khymenets, O., de la Torre, R., Saez, G., del Carmen Tormos, M., Toledo, E., Marti, A., Ruiz-Gutiérrez, V., Ruiz Mendez, M.

Goltsov phenomenon as a natural-technogenic electromagnetic discharge of the lithosphere

The article presents data on an unusual natural phenomenon that occurred on November 30, 1984 in the village of Goltsovka, Zmeinogorsky District, Altai Territory. It manifested itself in the passage above the village of a luminous ball, which was accompanied by an impact on the surface of the earth and led to some damage to structures and buildings. A detailed description of this unusual phenomenon in the published scientific literature, as far as we know, is practically absent. The article describes this phenomenon, based on data collected soon after the event, with the addition of upto-date clarifying information. A comparison is made with several known cases of ball lightning and a whirlwind. The conclusion is made about an unusually large energy release in the Goltsovka event
