The use of ethnopharmacological therapies is a part of human tradition. For centuries, they have been used in the treatment of diabetes, as well as other illnesses. The aim of this study was to examine the frequency of traditional medicine use in Serbia. The study was conducted as an online survey in February 2018. 130 people were surveyed, 55.38 % of which were people diagnosed with diabetes. The most commonly used herbal substituents were M. piperita L. (21 %), traditional herbal mixtures designed to regulate the primary and secondary diabetes complications (15%), M. chamomilla L. (13 %) and pharmaceutical supplements based on traditional recipes (10 %). 100 % of people with diabetes adhere to contemporary pharmacotherapy, while 25.86 % of people without diabetes do not use pharmacotherapy, but exclusively traditional medicine. There is no significant difference between the diabetic population that uses traditional medicine (51.34 %) and the one who does not (48.61 %), whereas in non-diabetic population the difference is significant (p < 0.05) so that 87.93 % of them regularly use medicinal herbs. More women than men use ethnopharmacological treatments (p < 0.05). The age of the respondents and their education also have an impact on the choice of therapy, so ethnopharmacological approaches are the most often used by faculty educated people aged 30 to 50 years. Moreover, people pay attention to the quality of supplements they use, i.e. 57.96 % of people buy them in pharmacies, 29.55 % with certified sellers, and only 12.49 % at the local market.

The skill of writing with the left or right hand is often taken as a hand lateralization predictor. Taking into consideration that such a manifestation is usually practiced, left-handedness often becomes 'concealed', making it harder to be phenotypically measured. The aim of this study is to determine the predictability of multiple manual skills in relation to the type of handedness. The sample of 756 primary-school students with the aid of Edinburgh Handedness Inventory showed that writing and drawing skills using a particular hand have a very clear mutual correlation (0.86 with the left-handed, and 0.50 with the right-handed). However, the correlation was not determined with other observed unimanual skills, such as throwing, using scissors, using a tooth brush, using a key and holding a glass. In addition to that, writing as such is not a reliable hand lateralization predictor. In relation to hand lateralization, writing shows a low determination coefficient with the left-handed, whereas for other skills R2 varies within the range 0.43-0.66. The numbers are similar to the right-handed, where R2 varies within the range 0.28-0.53, for all skills, except writing and drawing. A conclusion can be drawn that writing is not a reliable predictor of lateralization to left or right, but that those are skills in relation to which there is no cultural pressure.

In contemporary clinical practice bone substitutes such as implants are used in reconstructive orthopedics and maxillofacial surgery. Judging from physical and chemical properties each implant has some advantages and disadvantages. The idea of bone tissue engineering is to simulate the formation of bone to implants as carriers in combination with osteogenic cells and osteo-stimulative factors (osteoinduction). The design of the implant itself in terms of the chosen carrier with its own characteristics, the type of cells that have been implanted, the type and combination of stimulative factors play an important role in the behavior of the implanted material within a body. Tissue engineering looks promising, however a lot of obstacles have to be surmounted in order to consider it a proper alternative.

Bipedalism is the main characteristic of humans. During evolutin bipedalism emerged probably as an adaptation to a changing environment. Major changes in skeletal system included femur, pelvis, skull and spine. The significance of bipedal locomotion: Bipedalism freed the forelimbs for carrying objects, creation and usage of tools. In the upright position animals have a broader view of the environment and the early detection of predators is crucial for survival. Bipedal locomotion makes larger distances easier to pass, which is very important in the migration of hominids.

Handedness (dominant arm) is a term used to describe the ability of using right or left arm not only for writing but also for performing delicate and precise tasks. In fact, dominant arm appears even in prehistoric time. From the aspect of evolution, dominant arm is seen as an ability which correlates with speech development, and as such is related to cerebral lateralization. However, various cognitive disorders are connected to the dominant arm. The influence of inheritance and environment are equally important for the dominant arm, however their influence prevents us to determine how a certain arm becomes dominant.
