New paper on sardine and cod liver oil

The aim of the current study was to compare the biological activities of total polar lipids (TPL) and thin-layer chromatography (TLC) polar lipid fractions of sardine fillet and cod liver oil against atherogenesis. TPL and TLC polar lipid fractions obtained from these two sources were assessed for their ability to inhibit the platelet-activating-factor (PAF)-induced platelet aggregation (PAF-antagonists) or to induce platelet aggregation (PAF-agonists), since PAF plays a crucial role in the initiation and development of atherosclerosis. This study focused on the polar lipids since previous studies have underlined that the antithrombotic properties of foodstuffs are mainly attributed to polar lipid micro-constituents. TPL of sardine fillet induced platelet aggregation, while TPL of cod liver had a bimodal effect on platelets. TLC polar lipid fractions of both samples exhibited in vitro aggregatory and inhibitory activity towards platelets. However, TLC sardine polar lipid fractions showed stronger in vitro antithrombotic activities than the cod liver oil ones. These data constitute evidence of the putative contribution of fish polar lipids against cardiovascular diseases, underling firstly the beneficial effect of fish and fish lipids as functional foodstuffs against atherogenesis and secondly the more important role of sardine polar lipids as opposed to cod liver oil.

the challenging and unpredictable federal regulatory environment

this is a cute way to express the corporational disgust to activists who do - in a highly moral and unproffitable way!- their best to protect the Environment and the Future of our kids.

The phrase is from the Shell announcement about offshore Alaska drilling.

Challenging and unpredictable!


Let's remember then...

that People have the Power!

Sustainable functionality of Lipids

Here there is a realy good article on activities of omega-3 acids and some related issues.
The relevant scientific paper is here.

Apart from flux/uptake, I would suggest that we need to take into account the cardioprotective activities of polar lipids  but also their sustainability.

In this way, we can work towards increased food security but also sustainable functionality of lipids.

Start of new term: 26.10.2015

At this term, the following 5 programmes will be taught:
  • “Food Safety and Food Quality, ISO22000:2005 and ISO9001:2008”
This programme is a useful analytical and managerial tool in order to assess food risk and implement HACCP and ISO procedures (covering the requirement of both ISO22000:2005 and ISO9001:2008).
  • Food Chemistry, Food Technology and Nutrition
This programme provides the current knowledge and trends in Food Chemistry, Nutrition and Food Technology.
  • Crisis Management with emphasis on Nutritional and Environmental Crises”
  • “Training food industry towards exports and extroversion”
  • "Functional Food" where the principles of R+D in Food Industry are presented with specific case studies of functional food, giving all the necessary information and scheme of action from the designing of the concept of a novel food to the filing to EFSA of a novel health claim.

άλλη μια φορά στην Κάλπη...με μισή καρδιά αυτή την φορά


Ψήφισα και σήμερα...με βαριά καρδιά... στην εφορευτική επιτροπή ήταν 2 νέα παιδιά που με ήξεραν...το χαμόγελό τους βάλσαμο.

Είθε να κερδίσει η Ελπίδα κόντρα σε βαρουφα-μεϊμαρά-ντάιζελ-σόιμπλε-καρικατούρες.

Είθε να αποκτήσουμε ρεαλιστική κυβέρνηση με αριστερό πρόσημο!  

Χωρίς όμως δηλώσεις για κάψιμο μνημονίων και χορούς με ζουρνάδες...

Ας ξυπνήσουμε επιτέλους από τον εγωκεντρικό μας λήθαργο και ας δούμε την πραγματικότητα κατάματα χωρίς κόκκινα ή μπλε γυαλιά αλλά με διάθεση για προσφορά και φυγή προς τα εμπρός...

πολλά ζητάω εεε?

Y.Γ. και όπως λέει και ένας καλός φίλος

Απόψε πάλι κάποιοι θα μαζεύονται σε κύκλους.
Και θα πανηγυρίζουν και θα κραδαίνουν σημαίες.
Ακόμα και τσάμικα θα χορεύουν.
Κι εσύ θα στέκεσαι στο σκοτάδι (πάντα στο σκοτάδι) και θα ονειρεύεσαι τη μέρα (που θα πεθάνουν οι σημαίες).

eating time, choices and healthy eating

This is an inreresting study on how available time for lunch affects children's choices.

As parents, we need to find the time to dedicate to our kids to eat together and talk to each other about food choices...

στην κάλπη...

τελικά θα πάω με βαριά καρδιά, θα ψηφίσω το μη χείρον βέλτιστον, δεν θα πω σε κανένα αυτή την φορά τι ψήφισα...ούτε και σε σένα ιστολογιάκι μου.

Με την ελπίδα να μην αναστηθούν τα φαντάσματα του κοντινού παρελθόντος...


Assessment of the In Vitro Antithrombotic Properties of Sardine (Sardina pilchardus) Fillet Lipids and Cod Liver Oil

this is the title of our just accepted for publication paper in "Fishes", where we compare the nutritional value of sardine and cod oil. Sardine's lipids are more active in terms of cardioprotection. Once the full paper is available, I'll post it on the blog.

for Helena Smith, Athens correspondent of the Guardian

Ms Helena Smith, for us living in Athens, your article is miles away from the true value of Meimarakis. The guy is somehow non-existing...He wants to collaborate in order to defuse responsibility. His party, ND, has NO PLAN of action and most importantly they can't persuade any more millions of Greeks who have voted for them in the past.

The biggest problem today is that Syriza has similarly betrayed lots of people...And many people will not go to vote next Sunday...There is no clear plan by any party...

That's the biggest drama emerging for Greek people who are on the verge of poverty, unemployed for years and desperate for some hope, either "conservative" hope or "leftist" hope...

Sorry for being critical but the situation here, as you perfectly well know, is so critical, beyond any good looks and common sense of any Meimarakis...

η παιδεία πέθανε... Ζήτω η παιδεία!

τοίχος στο Τμήμα Χημείας, ΕΚΠΑ...ένας τοίχος που τα λέει ΟΛΑ!

ο τίτλος είναι παράφραση του γνωστού "ο βασιλιάς πέθανε, ζήτω ο βασιλιάς" και μου ήρθε στο νου διαβάζοντας τον συνάδελφο Γιώργο Τριμπέρη εδώ.

Με το γραφείο του Γιώργου μας χωρίζει μια τζούρα καφέ και όσα γράφει είναι πέρα για πέρα αληθινά.

Αλλά δεν είναι η ανυπαρξία των πολιτικών ταγών το μόνο πρόβλημα στα ΑΕΙ της Ελλάδας...

Το μεγαλύτερο πρόβλημα είναι οι ιθύνοντες εντός Πανεπιστημίων...

Έχουν οι φύλακες τελικά γνώση;


Υ.Γ. Στο Τμήμα Χημείας, η χρονιά που ξεκινά μάς βρίσκει...

ΧΩΡΙΣ καθαρίστριες,

ΧΩΡΙΣ τα απαιτούμενα αντιδραστήρια για τις ασκήσεις των προπτυχιακών φοιτητών,

ΧΩΡΙΣ πόρους για να πάρουμε φοιτητές στα μεταπτυχιακά προγράμματα.

Θα είναι μια χρονιά παρωδία... αλλά οι ιθύνοντες απλά παρακολουθούν...

Ως πότε άραγε;

eat the Med way...and avoid statins!

Here is some good news if you don't like eating pills.

If your eating patterns follow the Med diet guidelines, you could avoid statins and all their side effects.

More information on the effects of Med Diet to stop inflammation and hence cardiovascular diseases, is available at chapter 4 of the book "Marine Oils"

farewell to Aylan and Ghalib and their mother Rehan

Good Bye Dearest Aylan, Ghalib and Rehan!

Aylan Kurdi, left, and his older brother, Ghalib. Photograph: Twitter

This "european" "society" was not ready to accept you...

You see, here in Europe we don't really care about Syrian war and its casualties.

Here in Europe, we are very introvert. We want jobs and good salaries. That's all.

In order to make money, we produce weapons and army officers... These humans and these machines are the main causes of the Syrian catastrophe that your father/husband tried to rescue you from...

It is quite tragic that your family's application to enter Canada was rejected.

It is rather tragic that many European politicians think that by building a wall they could divert refugees.

It is quite hypocritical though...when the same political parties are, one way or another, behind the catastrophe in Iran, Iraq, Afghanistan, Syria...

The west divides and reigns...
But not anymore...

With so many souls drowned in Mediterranean Sea, like you, the Erinyes should make the sleep of the governing politicians much less comfortable...

Good Bye Aylan, Ghalib and Rehan.
