Prof. Monika Kaczmarek in the 2017 Golden Ten of W&M Women of Success
The 19th ceremony of Warmia and Mazury Women of Success honoured most exceptional women in the region and took place in Olsztyn on March 7th, 2017. It is our great pride that Prof. Monika Kaczmarek – head of Institute’s Laboratory of Molecular Biology, is one of the distinguished laureates.
The ceremony of Warmia and Mazury Women of Success serves the aim to recognize the most influential women of the past year in different areas of life such as culture, politics, business, science and charity.The candidates are put forward by the representatives of regional media, social organizations and local governments. The choice of the golden ten is made by a committee composed of region’s most well-recognized authorities.
„Street Labirynth” seen by a chemist
What does Brussels, Palermo, Sofia or Instambul look like in the camera eye of a professional chemist?
We would like to invite you to a photography exhibition „Street Labirynth” by our colleague, Dr. Michał Janiak – a professional food chemist and an after-hour enthusiast of photography, distinguished by the National Geographic Channel in 2016. You can visit his exhibition in „Planeta 11” library until 31th March 2017. The finisage of the exhibition will take place on 24th March at 18:00

Maternal nutrition and health of next generations
Prof. Monika Kaczmarek, Head of Molecular Biology Core Facility
Challenges of contemporary medicine
So far it has been demonstrated that the nutritional status of mother may affect a normal development of the embryo and fetus in the womb, and after birth, determines health of the offspring. This September, English researchers published in Pediatric Obesity Journal a prognosis for 184 countries regarding obesity and related health problems in school children. It is estimated that without an adequate policy challenging current trends, by 2025 268 million children aged 5-17 will be overweight, with 91 million of them to suffer from obesity.
Infertility has always affected humans, yet unfortunately we can now observe a considerable decrease in the pregnancy rates caused by inter alia environmental factors. World Health Organization (WHO) clearly demonstrates that 10% of women worldwide are trying to get pregnant with no success, and this situation has not improved in the last 20 years.
Nutritional programming
It appears that the period from conception until the age of 3 is marked by increased sensitivity to environmental factors, such as lifestyle, diet and parents’ health status. The process in which nutritional status determines metabolic balance in the organism is called nutritional programming. So far it has been demonstrated that the nutritional status of mother may affect a normal development of the embryo and fetus in the womb, and after birth, determines health of the offspring. Proper „designing” of offspring within the process of nutritional programming has long-term prohealth effects and may prevent the development of diet-induced diseases such as cardiovascular disorders, obesity, hypertension and diabetes type II.
In the mother’s womb
It is interesting that excessive weight gain during pregnancy occurs more frequently than in the past century. Unfortunately for us, children of women who put on too much weight during pregnancy were observed to suffer from an increased risk of obesity at the age of 34. Therefore, women having a Body Mass Index (BMI) within the normal range (18,5-24,9) are recommended to gain 11-16 kg during pregnancy, while those with the BMI 25 – 29,9 and BMI ≥30 only 7-11 kg and 5-9 kg, respectively.
After birth
The effects of nutritional programming may be observed not only in the cells of an individual with improper eating habits, but – in the case of pregnant or lactating females – also in their children or grandchildren. Our research based on animals fed a strict diet during lactation revealed inaccuracies in the development of offspring’s reproductive functions despite introduction of a proper diet in the future. These mice achieved sexual maturity later and suffered from a series of disorders affecting their fertility. What is interesting, the effects of improper diet of lactating females were noticeable even in the second generation – in grandchildren.
Even though the conclusions drawn from the studies based on mice cannot be directly translated to humans, there are numerous report on the influence of distorted metabolic balance on the increased risk of development of diabetes, obesity and other diseases in adulthood. Therefore, we shall bear in mind that during pregnancy we are advised to eat for two, but not twice as much, and not follow any strict diet. We shall obey this rule also when lactating. Then, let’s lead a considerate lifestyle and pass it on to our children and next generations.
