Caffè e diabete non vanno tanto d’accordo
Assumere caffè soprattutto dopo i pasti ha un effetto negativo sulla glicemia post-prandiale:
+9% dopo la colazione, +15% dopo pranzo, addirittura +26% dopo cena. È il risultato di un piccolo studio condotto da ricercatori della Duke University Medical School di Durham (Usa). L’autore ha anche sottolineato che “nelle persone sane il caffè non ha effetti collaterali come questo, e anche fra i diabetici potrebbero esserci persone più o meno 'sensibili' agli effetti negativi legati al consumo massiccio di questa bevanda".

Ancora dal Framingham Heart Study
Pubblicato da Ralph D'Agostino, in forza al Mathematics and Statistics Department della Boston University, un algoritmo in grado di calcolare i fattori di rischio cardiovascolari specifici per genere. Si tratta di un software la cui analisi si basa su dati tratti dal Framingham Heart Study e che può essere particolarmente utile per i medici di famiglia.

Sintetizzato il DNA completo di un batterio dagli scienziati dell’istituto Venter
Un passo ulteriore verso la “biologia sintetica”
WASHINGTON — It's another step in the quest to create artificial organisms: Scientists have synthesized the complete DNA of a type of bacteria. The experiment, published online Thursday by the journal Science, isn't a living germ, just its genetic structure.
But scientists from Maryland's J. Craig Venter Institute called it the largest manmade stretch of DNA to date, and therefore a logical step in the fledgling field of "synthetic biology" that aims to build new organisms that work differently than nature intended, such as producing new fuels.
The Venter group started with some off-the-shelf laboratory-made DNA fragments. They overlapped and joined these stretches to make ever-larger chunks of genetic material until they finally had a manmade copy of the entire genome of a small bacterium called Mycoplasma genitalium, a genital germ. Last year, Venter's team performed a "genome transplant":
Researchers transplanted all of the genes from one species of Mycoplasma into another, switching a goat germ into a cattle germ. Somehow, the transplant itself sparked the donor genes to start working; Venter uses a computer analogy to say it "booted up."
Now he must test if this new artificial Mycoplasma genome can boot up, too — by putting the DNA into a living cell to see if takes over and becomes a synthetic organism.
"I don't view that we're creating life," Venter told The Associated Press last year in describing this series of experiments. "I view that we're modifying life to come up with new life forms by designing and synthetically constructing chromosomes."
Il trattamento chirurgico dell’obesità può anche curare il diabete
Obesity Surgery Seen As Diabetes Cure
According to Australian researchers a new study gives the strongest evidence yet that obesity surgery can cure diabetes. Patients who had surgery to reduce the size of their stomachs were five times more likely to see their diabetes disappear over the next two years than were patients who had standard diabetes care.
