Did you know that Peter Jackson before performing the Seigneurdes rings was a filmmaker at a very low budget gore? (See forexample " Braindead" or "Bad Taste" ...) Autrefilm well suited to our topic of the day: "Sweeney Todd the diaboliquebarbier of Fleet Street" by Tim Burton. And what about the series Dexter , where the main character is an expert analysis of bloodstains etégalement a serial killer. You guessed it, our topic today is the blood. Star of horror films, its bright red color makes enalerte our senses, and just to look the most sensitive (C'estd'ailleurs why the Orcs have black blood and not red in the Lord of the Rings : éviteainsi we ban the movie at least 12 years ...). But what is due cettecouleur so intense? And why not oxygenated blood veins is represented iltoujours darker or bluer than oxygenated blood desartères?

blood with hemoglobin

What's the blood? Well mission centrifugal blood there are three fractions: plasma rather yellow is the liquid portion of blood, it is 55% of whole blood, platelets and white lesglobules (less than 1%) and finally the famous globulesrouges called erythrocytes in humans that correspond to 45% of total volume (PCV s'appelleégalement This percentage, an analysis blood).

These RBCs give blood its red color, this sontdes cells without nuclei and organelles practically, they contain a single protein pourl'essentiel: the famous hemoglobin . These sacsd'hémoglobine mission is to carry oxygen Entire organismegrâce this protein with remarkable properties (I'm sure all fans of the animated fameuxdessin " Once upon a time ... Life " remember).

The structure of hemoglobin

The protein is composed of protein subunits 4sous, globins: two andtwo α β, each sub subunit is linked to groupof non-protein, heme, hence the name: "hemoglobin". This contains a heme iron atom which may seli with the oxygen molecule. Each million moléculesd'hémoglobine a red blood cell can carry 4 molecules dioxygène.L space reserved for oxygen, is not used to transport ledioxyde carbon (CO 2 ), cons by carbon monoxide (CO) is small enough to be fixed classical rayleigh quasi-irreversible at this site. As the place of O 2 is taken, lemanque oxygen soon becomes apparent even at low concentrations of CO ... This is the origin of carbon monoxide poisoning often linked to other boilers and stoves Devieux evil resolved.

[ Haemoglobin: a protein quaternary àstructure, that is to say composed of subunits. (2 α and 2 β) ]

A color variable according degréd'oxygénation.

In the absence of O 2 attached to hemoglobin, the iron atom II (ferrous) linked by a weak bond to an amino acid (histidine) is offset from the plane of the heme. It exceeds like it was drawn on the side by his association with histidine. Moreover, the distribution of electrons around the nucleus that the overall diameter of the atom is important. We're talking high-spin configuration. Conversely, when the oxygen binds to the iron atom on the side opposite to that of histidine, it takes a perfectly centered position relative to the plane of the heme, and its diameter is reduced: this is called configuration low spin. Cettesimple difference between the configuration and high spin low spin and the changes that accompany it, are sufficient to créerune significant difference in the absorption spectrum of the molecule, autrementdit, color. And oxyhemoglobin absorbs much less lescouleurs wave red (approx. 660nm) than deoxyhemoglobin, which therefore appears moinsrouge. Its appearance is duller, closer to the blue, and that is the reason decet conventional representation of non-oxygenated blood in blue and red sangoxygéné.

Hemoglobin, pigmentrespiratoire qualified because of his color, is not the only molecule to ensure cettefonction carrier O 2 in the animal world. In crustaceans and molluscs ouch, we find the hemocyanin, which has two atoms decuivre. The oxidized copper atom then gives a blue-green blood.

Reflection before the crib

Like the child from the nursery because I love life and children, but I do not believe in stories that are told about it. I think he was a man born to an unwed mother pregnant with a Roman legionnaire and collected by a brave man who married her, thus preventing it from being stoned. But her child had a special destiny, feel a bit: sure he had the task of reforming Israel, he was crucified for political reasons. His death then gave birth to a legend and a new religion that was to change the world.

matter that my story is not that the letter of dogma, the important thing is the spirit that is fermented in the Christian dough, and never mind the so-called Christian institutions! The story of Jesus can be revisited and renewed institutions, most of life is the promise made by the child that makes me a Christian because I love life.

Yes I am a Christian because I believe in eternal life and all the promises of earthly life. Before that child from the nursery I marvel, as the ass that I'm probably like beef or merely that I may be, unless I am the magician who has followed the star and sees beyond the horizon? Who am I? I do not know, except that I am a man who loves life body and soul, and who constantly gives thanks to God for this blessing of being and loving.

I am also a father who loves his child (I had five) and the wife who loves Mary, but every woman I honor both the vestal virgin Venus-Aphrodite, how to love life as if we do not sanctify human love? I do not fear death is that way, but I fear the evil, evil physical and especially moral evil.

Yes I am a Christian because it is through the promise of this child that I go to Him, Father I pray that through this Our Father taught by the child of the manger, Jesus ignored this but was, no doubt of the messenger of Life, the Son of the Father, but we all are.

The tragic Christmas Easter passion of Iraqi Christians

According to UNHCR thousands of Christians fleeing the central Iraq to seek refuge in Kurdistan or abroad. We have lost count now that half a million Christians in Iraq cons 800 000 to 1.2 million in 2003. In Strasbourg

three bishops from Iraq seeking help were received by the archbishop of Strasbourg. Faced with radical Islam the situation of Christians is becoming increasingly untenable. The three bishops were meeting in Strasbourg, European Parliament President and the heads Council of Europe.

Caritas and Catholic Relief Services were awarded to the three bishops donate money to help their followers. On the occasion of this meeting was an Our Father said in Aramaic, the language of Christ is still spoken in some churches in Iraq but for how long?

the approach of a tragic Christmas for Christians in Iraq can not remain silent on the ongoing tragedy, let us pray! help with our donations! especially breaking the silence of a guilty conscience!

Congratulation Messages For Mothers

It was once on the road to Santiago, footnote 9

villages and medieval times ... Lauzerte dog, Moissac, St Anthony, Lectoure Condom.

Exhausted by sweltering heat and heavy and the long march of the stage, my fellow Canadians do not follow me when I decide to sleep Lauzerte medieval village perched on a hill. I therefore abandoned mobile homes in a campsite at the foot of the hill and after a last effort I sit all alone in the Principalities cottage situated in a beautiful old house overlooking the plain. With a square surrounded by arcades, Lauzerte worth a stop and then I relax at a sidewalk cafe under the arcades. The evening the storm broke and I enjoy a magical show from the window of the house. The heat wave ends in a deluge of water. The problem is it still raining the morning, then all day, so this is tempered in the evening I arrived in Moissac. Fortunately, the guesthouse located in a former Carmelite convent is very comfortable and even offers to pilgrims dryers. So dry and after a last look at the famous facade of the church of Moissac that I take the road under heavy showers and gusting winds. I admire the beautiful architecture of the granary of Auvillers and I step to St Anthony, a former hospice pilgrims whose church is marked by architectural influences Mozarabic, we feel that Spain is approaching.
I discover Gascony region I do not know. Now I walk along the canal side of the Garonne, the weather is bad and I reach Lectoure by road, the trail being turned to mud. I guess then what the progress of medieval pilgrims who often walked barefoot. In a village called Miradoux, the baker gives me a yogurt with bread and asks me in return to pray for him to Compostela. He is a former steelworker Longwy converted back to the bakery and seeking peace. I promise to pray for him and resume my journey under the gray sky. I also pray for Andre and Jean-Yves, two friends with cancer (they still live on Christmas Eve 2010). That was in 2003 and one had cancer of the pancreas and one from lymphoma. I also pray for my little Bertrand and evening to learn that he will step better. Lectoure after the weather becomes warmer, but I remain on the county to avoid the mud. My fellow Canadians have disappeared under the downpour, I walk alone for three days, but I found both Condom Norwegian with whom I partied in Cahors wine in the company of trappers québécois.Le gîte Condom is located in a former College of Oratory, it offers stunning architecture and nostalgia of an old-time education. On the doors of the old classrooms it says "math" or "rhetoric". I guess the students lined up in silence before classes in school time when the word still had meaning ... Condom is a charming city and has a museum condom ... as it should. I appreciate the humor of the little city councilors who built this museum no doubt interesting, but as for me I prefer to collect myself in the cathedral and immerse myself in beauty and peace before going to sleep in the memories of old college.
