Nutritional and Metabolic Diseases - Science topic

Thank you for you response

Studies in recent years has been shown the FTO role in cell metabolism through mTOR pathway. so we expect the FTO gene expression can influenced by many dietary factors such as calorie intake, dietary protein, dietary fat and so on.

But about The gene expression changes in blood cell, we don't know anything...

Dear Dr Vaccaro, I have studied human nutrition many years ago when there were not the ISPP. The best way to become proficient in a subject, in my opinion, is to do research and teach that topic. To do research you have to study hard, ask you questions, analyze the methods for answers. To teach you have to study even more, you have to know how to grasp the essentials, but above all always have students or young researchers who will "push" with their questions and their intelligence.

Even the clinical observation is obviously essential, but the field of dietetics is very difficult, because there are many variables involved and the observed effects (I mean the effects of diet) are often mild and are seen in the medium to long term. In other areas of medicine it is easier to learn by experience, in the case of the diet I think is very very difficult (in the face of what appears on the Internet, where everyone knows everything and knows for sure). In human nutrition all doctors, all biologists, all pharmacists, and even half of the citizens, believe they are experts, even if they have not studied. This causes many errors and much confusion. Therefore, I am in favor of in-depth, controlled graduation systems, possibly after Medical studies..

Whereas severe hypophosphatemia may lead to acute hemolytic anemia, decreased myocardial contractility, neuromuscular disturbance, respiratory weakness or even rhabdomyolysis and altered mental status, its impact on survival remains questionable.

At evidence no effect in DKA In contrast with a potential prognosis factor in case of AKI which received CVVH therapy.

Even, if we observed rare case of acute severe hypophosphatemia in acute exacerbation of COPD, its role on respiratory failure could not be established: severe respiratory acidosis or metabolic alkalosis during the first days of mechanical ventilation???

Two publications could be helpful, but the question remains of interest.

The Truth about L-Carnitine Side Effects

The Truth about L-Carnitine Side Effects

As you may have read or heard in the news lately, a new study published in the journal Nature Medicine suggests that the L-carnitine, not the saturated fat, found in red meat is the real culprit in heart disease risk and that L-carnitine supplements are unsafe and have side effects. Folks, this is just the latest example of the pitfalls associated with mainstream media reporting and medical research.

First of all, the study authors state that gut bacteria convert carnitine into a compound called trimethylamine-N-oxide (TMAO), and they believe that TMAO allows cholesterol to build up in artery walls, thereby raising heart disease risk. However, even if carnitine is converted to TMAO, it is highly unlikely to be a primary player in red meat’s adverse health effects, as the researchers theorized. Here’s why.

A pound of steak contains approximately 400 mg of carnitine, some of which is likely converted to TMAO. But a pound of fish contains 1,700 mg of TMAO. So if TMAO is the real culprit then why is fish, which contains much more TMAO than what your body would convert from the L-carnitine found in red meat, universally accepted as being cardio-protective?

No Studied L-Carnitine Side Effects with Normal Usage

As for the suggestion that L-carnitine side effects are harmful, this is simply a matter of guilt by association. The researchers state that when mice were fed the human equivalent of 26,000 mg of carnitine per day, they developed arterial blockages—that equate to 26–52 times the normal supplement dose of 500–1,000 mg!

Furthermore, all of the news reports neglected to mention any of the previous human clinical trials and other studies that demonstrated carnitine’s significant benefits, including those studies using rabbits, which are considered to be the best model of human heart disease.

The bottom line: I stand by my recommendation of 500–1,000 mg of supplemental L-carnitine per day.

Now it’s your turn: Do you take L-carnitine supplements?

Dear Udoh, the study that has been done at Khartoum Sudan in tanneries may in one way correlate industries, chemicals, waste products and skin complications, hope you find some of the points you are looking for.

I would recommend the most "normal" formulation you can find. In my lab, we use Humulin R, but any simliar brand should work. I don't use any of the especially fast acting analogs, just plain insulin. Get your baseline, inject IP and begin collecting your time points.
