Contents of vitamins B1, B2, B6, and B12 in pork and meat products

2001

The concentration of B vitamins (B(1), B(2), B(6), and B(12)) was determined in three pork muscles (Longissimus dorsi, loin; Biceps femoris, ham; and Triceps brachii, shoulder) and in pork and other meat products (cooked, pickled, and cured), of importance because they are consumed in high quantities. The results were compared with values reported by other authors and their contribution to the daily intake of these vitamins estimated. This showed that pork provides, on average, 97, 25.8, 35/43.7 (men/women), and 37% of the RDA (Recommended Dietary Allowances) for vitamins B(1), B(2), B(6), and B(12), respectively.

Fostering antioxidant defences: up-regulation of antioxidant genes or antioxidant supplementation?

2007

Vitamins have traditionally been considered as food components that are required in the normal diet to prevent deficiencies. However, a newer concept of the function of vitamins in nutrition has taken them beyond simply prevention of deficiency symptoms. This concept considers that many vitamins, when taken in relatively larges doses, have important functions beyond preventing deficiencies. Linus Pauling was instrumental in putting forward this concept, particularly for vitamin C. Thus, relatively high intakes of vitamins, and in particular vitamins C and E which are antioxidants, are considered to be healthy for the human population. This may be true in some special situations such as, for…

Is At Least One Vitamin Helping Our Vasculature?

See related article, pp 1290–1298 Cardiovascular risk factors such as diabetes mellitus, arterial hypertension, chronic smoking, and hypercholesterolemia are cardiovascular risk factors known to be associated with endothelial dysfunction, a condition that may predict long-term progression of atherosclerosis as well as cardiovascular event rates (for review, see Munzel et al1) Although the mechanisms underlying this phenomenon are complex and multifactorial, there is growing body of evidence that oxidative stress attributable to increased production of reactive oxygen–derived free radicals may play a pivotal role in this process.2 Increased superoxide production by enzyme systems such as the…

L’uso del WHOQOL-BREF e dello EUROP-ASI nell’assessment dei disturbi da uso di sostanze: un’indagine comparativa

2010

Lo scopo del presente contributo è rintracciare, attraverso alcuni dati di ricerca, l’esistenza di correlazioni significative tra i punteggi compositi delle diverse aree dello EuropASI e le sezioni della forma breve del WHOQOL in pazienti con disturbo da uso di sostanze, con l’obiettivo di osservare le relazioni esistenti tra l’autovalutazione del benessere soggettivo e la valutazione degli operatori sulla gravità dei problemi connessi alla dipendenza da sostanze. La ricerca ha coinvolto un gruppo di 30 pazienti afferenti ad un Ser.T. del Distretto 13 della AUSL 6 di Palermo. I pazienti sono stati selezionati random, secondo i seguenti criteri di inclusione: diagnosi di dipendenza da sostan…

In Principio era l'azione. Forme di vita e linguaggio nell'opera di Ludwig Wittgenstein

2018

The work aims at providing an analysis of the concept of «Forms of Life» (Lebensformen) in Wittgenstein’s philosophy and at highlighting its social and natural aspects. The first part revolves around the debate between the empirical and transcendental interpretations of this term as well as the introduction to the general issue of the naturalistic and / or cultural representation of forms of life. In the second part the research focuses on the clarification of the concept «Lebensform» making reference to the numerous texts in which it appears and illustrates how some semantically linked terms, such as «animality», «image of the world» and «perspicuous representation» play a significant role…

Poner el trabajo al servicio de un proyecto de vida : estrategias contra la precariedad

2019

A partir de 20 historias de vida, este artículo se propone presentar las estrategias que algunos jóvenes italianos altamente cualificados han encontrado para eludir la doble amenaza de la precariedad laboral y de la invasión del trabajo en la vida. Centrando sus biografías en un proyecto de innovación social o ligado a la vertiente expresiva del trabajo, los jóvenes investigados se han enfrentado a un destino de explotación, incertidumbre, fragmentación e individualización del itinerario laboral y vital, común a una generación entera. Se ha utilizado la técnica de la entrevista en profundidad. La investigación ha permitido identificar en sus discursos las siguientes estrategias: 1) colocar …

Stillage as a Source of Growth Promoting Biofactors and a Stimulator of Levan and Extracellular Levansucrase Synthesis for Zymomonas mobilis

2002

In the present work, the fermentation of simultaneous production of ethanol and levan by Zymomonas mobilis grown on different growth media has been studied. Yeast extract, rye stillage or sugar beet molasses stillage were used as additives to the basic sucrose media and the chemical composition, including vitamins, of the cultivation liquids have been determined. It has been shown that 0.5 % of yeast extract dry weight additive could be substituted by 10.0 % of native stillage additive. It was established that molasses stillage stimulates the ethanol synthesis, but rye stillage additive is more preferable for levan production. The extracellular levansucrase obtained from the culture liquid …
