Bisphenol A - endocrine disruptor

Bisphenol A

Bisphenol A is a widely know endocrine disruptor linked to metabolic disorders and suspected to be involved in metabolic syndrom and type 2 diabetes progresssion.

But do you know where it is accumulating?

A. in the brain?
B. in muscle mass?
C. in bone tissues?
D. in fat mass?



According to a recent publication from Fénichel, most Endocrine disruptors are accumulating in Fat Mass. However, other older publication pointed out the role of the route, dosage, gender, species…This raise the need of more studies, taken into account the amount of BPA spread in the nature and the industrial use.


Heat and Biomarkers

Heat Biomarkers Did you know Bertin Bioreagent

Have you ever heard of  “Summer stress”?

Heat puts stress on your body’s cooling system.

When combined with other stresses such as hard physical work, fatigue or some pre-existing medical conditions, it may lead to heat-related illness, disability and even death.

To better understand, let’s take a look at this practical case highlighting importance of seasonal variation in cortisol biomarkers…Results are edifying!





What was the first neurotransmitter to be discovered?

Neurotransmitters Did you know Bertin Bioreagent

In 1921, Otto Loewi , a German pharmacologist and psychobiologist  identified the first neurotransmitter in an experiment that came to him…in a dream!

Do you know about this amazing story? 


Answer: The acetylcholine!

"Ironically, Otto Loewi is better known for the way in which he came upon the idea that won him the Nobel Prize than for the discovery itself."


Gout: The Painful Disease of…Dinosaurs!

Dinosaure Pain and Inflammation Did you know?

Gout, which affects about 3 million people every year, causes pain and inflammation in the joints, like arthritis. It’s caused by the build up in the blood of a substance called uric acid, which generates sharp crystals inside joints.

 Did you know that dinosaurs struggled with arthritis just like humans?

 How can we tell? Let’s have a closer look at their bones…


"Some 70 million years ago, a duck-billed dinosaur lived alongside a shallow sea covering what is now New Jersey—and it had a real pain in the arm. At long last, paleontologists are giving it a diagnosis: septic arthritis, a bone disease that often develops when an injury is followed by infection. Even though the scientists had nothing more than two fossilized arm bones to go on, the fossils contain enough evidence to make the postmortem analysis possible. Such an analysis, they add, offers a unique, if painful, window into dinosaurs’ daily lives."

Who’s the man behind Insulin?

Insulin Frederick Banting Bertin Bioreagent

Discovery of Insulin coupled with its purification helped transform childhood diabetes from a fatal disease to a chronic illness.

But who was this unknown, at the time, surgeon behind its discovery?

November 2016 was his 125th anniversary…Any clue?

Answer: Frederick Grant Banting,  Nobel Prize in Medicine in 1923!

"In the early 1920's, the Canadian Surgeon Frederick Banting extracted a compound they named insulin from the islets of Langerhans in the pancreas. When injected into diabetic dogs, the compound decreased the levels of sugar in the dogs’ blood and urine. The discovery, coupled with the purification of insulin, helped transform childhood diabetes from a fatal disease to a chronic illness."

Cancer sex bias

Did you know Cancer Sex Bias Bertin Bioreagent

Does Cancer sex bias exist?

There is a striking and yet unexplained male predominance across many cancer types.

A recent article of the journal Nature Genetics might bring us some important answers. 

Answer: Tumor-suppressor genes that escape from X-inactivation contribute to cancer sex bias!

According to an article from Nature Genetic (21st november 2016), "a subset of X-chromosome genes can escape X-inactivation, which would protect females from complete functional loss by a single mutation."

An Hybrid technology

LC-MS asthma test Bertin Bioreagent

An Hybrid technology to help Asthma diagnosis ?

A new test to diagnose asthma from a patient’s saliva has been developed by a team of British scientists.

Painless, it would offer a one-stop diagnosis suitable for people of all ages.  Can you guess what technology is behind it?  

  • GC-MS
  • LC-MS
  • GC-IR
  • LC-NMR


Answer: LC-MS! 

"A new test that uses liquid chromatography-mass spectrometry (LC-MS) to diagnose asthma from a patient’s saliva has been developed by a team of British scientists.

Around 5.4 million people currently receive treatment for asthma in the UK, of which 1.1 million are children. To diagnose the condition, doctors usually measure a person’s airflow lung capacity, however lung function tests can be inaccurate and do not reflect the underlying physiological changes associated with asthma. Other tests, such as blood, urine or sputum analysis, can be distressing, particularly for younger patients.

The new test, which is reported in a recent paper in Analytical Methods is completely painless and offers a one-stop diagnosis suitable for people of all ages..."


Obesity/Diabetes: The Twin Epidemics

Obesity Diabetes Bertin Bioreagent

The link between obesity and type 2 diabetes (90% of all diabetes cases)  is of such interdependence that the term 'diabesity' has been invented.
In fact, obesity is believed to account for the risk of developing type 2 diabetes of:

  • 90-95%
  • 80-85%
  • 60-65%
  • 30-35%


Answer: 80-85%!

"There are many risk factors for type 2 diabetes such as age, race, pregnancy, stress, certain medications, genetics or family history, high cholesterol and obesity. However, the single best predictor of type 2 diabetes is overweight or obesity. People who are overweight or have obesity have added pressure on their body's ability to use insulin to properly control blood sugar levels, and are therefore more likely to develop diabetes..."

Mitochondria Color

Mithochondria color Bertin Bioreagent

What color is a mitochondria?


“Mitochondria are virtually the only colored parts of the cell. If it were not for the melanin in our skin, the myoglobin in our muscles, and the hemoglobin in our blood, we would be the color of mitochondria! 

And if this were so, we would change color when we exercised or ran out of breath, so you could tell how energized someone was from his or her mitochondrial color. Some insects are colored only by their mitochondria and change color when they fly.”

Florence Barrett-Hill Skin Treatment Therapist CIDESCO and ITEC Diplomas

So what’s this color?

Answer: Brownish red!

ROS - Half-life

ROS Half-life Bertin Bioreagent

High level of Reactive Oxygen Species (ROS) lead to DNA damage. Their detection are therefore primordial for DNA Repair solution researchers. But, their high activity and extremely short life make their measurement a major challenge!


Can you guess a ROS' half-life time?

  • A. < 0.04 μs
  • B.  2  μs
  • C. 164 μs
  • D. > 200 μs 


Answer: <0.04μs! 

Half-life is the time required for the amount of something to fall to half its initial value. ROS half-life is extremely short... Incidentally, the average human eye blink takes 350,000 microseconds!




Ant immunization - Bertin Bioreagent

Other species immunize, too!

When a deadly fungus infects an ant colony, the healthy ones  use  “social immunization”. They do not ostracize their contagious nest mates . Instead, they welcome them…

How do they fight back the infection?

Answer: They lick the infected ones!

 Indeed, according to a study of Plos Biology, the ants "lick their infected neighbors to remove the fungal spores before the pathogens sprout and grow. Apparently, such grooming dilutes the infection, spreading it thinly across the colony. Instead of leaving their infected peers to deal with the infection on their own and die, healthy ants share the burden, deliberately infecting everyone in the colony with a tiny dose of fungus that each individual's immune system can clear on its own. Such "social immunization" also primes the immune systems of healthy ants to battle the infection."

Dietary Fatty Acids

Fatty Acids Bertin Bioreagent

It is widely known Fish is good for Heart Condition. But, are you able to name at least 5 reasons why?

Cayman Current Issue 25 gives you the answer:

“Epidemiological, clinical, and animal studies provide substantial support that the long chain ω-3 fatty acids from fish and fish oils, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are cardioprotective, particularly in the setting of secondary prevention. Population studies have shown that ω-3 fatty acids have anti-arrhythmic effects that protect against sudden cardiac death. ω-3 Fatty acids benefit multiple cardiometabolic risk factors including blood pressure, vascular reactivity, arterial compliance, cardiac function, and lipid metabolism, as well as having antithrombotic, anti-oxidative, and anti-inflammatory actions.” - Cayman Current Issue 25
