Breastfeeding women in cities consume more caffeine than those living in rural areas. Breastfeeding mothers with secondary education are more likely to use caffeine products than those with higher education, and women aged 34-44 are more likely to use them than younger mothers, says Aleksandra Purkiewicz from the Doctoral School of the University of Warmia and Mazury in Olsztyn.
According to researchers from the Jagiellonian University, in the future it will be possible to treat organ fibrosis using the forces of nature. The researchers want to use extracellular vesicles, i.e. nanostructures secreted by cells of various organisms.
Researchers from the Wrocław Medical University are the first in the world to have faithfully recreated Theriac, a medicinal hit in Europe from antiquity to the 18th century, consisting of 71 substances. It turns out that it was closer to a placebo than to the miraculous mixture that ancient medics believed it to be.
A team of Polish researchers from the University of Warsaw developed a new mRNA modification in collaboration with several other units. The modification may be of key importance for the development of modern medicine, including targeted therapies, treatment of rare diseases and cancer vaccines.
Scientists from from the Warsaw University of Life Sciences (SGGW) are working on a dressing with the addition of a graphene monolayer to be used on superficial skin wounds. This solution could potentially result in faster and better healing of wounds in humans and animals, the university reports.
Too much light at night not only interferes with astronomical observations and disrupts the behaviour of animals and plants, it can also threaten people, disrupting sleep, promoting obesity, depression and even cancer, said participants of the interdisciplinary seminar 'The Dark Side of Light - light pollution and its impact on our life'.
Antibiotics are considered one of the greatest achievements of 20th century medicine. Their introduction reduced mortality due to bacterial infections and contributed to the extension of life expectancy. However, the consequence of their mass use in humans and animals is the emergence and spread of strains resistant to these drugs. According to estimates, in 2019, 4.95 million people around the world died due to antibiotic resistance, including nearly a million children.
How does vitamin D protect against the most common diseases and at the same time promote healthy ageing? The key to explaining the mechanism may be linking the body's individual response to vitamin D with immunocompetence (potent immunity).
‘Diet can support or negatively impact the gut microbiota. In the latter case, we will quickly notice symptoms not only in the digestive system, but also mental well-being,’ says Dr. Joanna Jurek, a biomedicine and human immunonutrition expert.
Scientists intend to block a certain receptor in prostate cancer cells that is responsible for its growth. Known as 5-HT5AR, the receptors near the tumour increase the amount of serotonin, a neurotransmitter called the happiness hormone. However, serotonin also promotes the development of cancer and leads to metastases.
