AbstractTinnitus is an auditory phantom perception in the absence of an external sound stimulation. People with tinnitus often report severe constraints in their daily life. Interestingly, indications exist on gender differences between women and men both in the symptom profile as well as in the response to specific tinnitus treatments. In this paper, data of the TrackYourTinnitus platform (TYT) were analyzed to investigate whether the gender of users can be predicted. In general, the TYT mobile Health crowdsensing platform was developed to demystify the daily and momentary variations of tinnitus symptoms over time. The goal of the presented investigation is a better understanding of gender-related differences in the symptom profiles of users from TYT. Based on two questionnaires of TYT, four machine learning based classifiers were trained and analyzed. With respect to the provided daily answers, the gender of TYT users can be predicted with an accuracy of 81.7%. In this context, worries, difficulties in concentration, and irritability towards the family are the three most important characteristics for predicting the gender. Note that in contrast to existing studies on TYT, daily answers to the worst symptom question were firstly investigated in more detail. It was found that results of this question significantly contribute to the prediction of the gender of TYT users. Overall, our findings indicate gender-related differences in tinnitus and tinnitus-related symptoms. Based on evidence that gender impacts the development of tinnitus, the gathered insights can be considered relevant and justify further investigations in this direction.

In the present work the effect of the use of synthetic sound during incubation in chicken of the Hampshire breed was studied. For the stimulation, an electronic sound generator with amplitude of power 1250 mV and time interval of 134 ms, 176 ms, 210 ms and 380 ms was used. The study was carried out in three experiments. In the 1 st experiment we tried to determine the influence of sound stimulation on the hatching of chickens from egg set of the variant of weight. In the 2 nd experiment we tried to determine the influence of the variant of the beginning of sound stimulation on chicken hatching. In the 3 rd experiment we tried to determine the influence of sound stimulation with constant amplitude of power and the variant of the time interval on chicken hatching. The most suitable eggs to be used for the stimulation with synthetic sound are the ones with the weight of 58.0-60.0g. In this weight category, the chickens hatched earliest of all the groups and there was no decrease in hatchability either. In order to achieve an earlier beginning of beak clapping, a faster whole group beak clapping time, and a shorter hatching time of chickens, sound stimulation should begin at the 433 rd hour of hatching. At the constant amplitude of power of the stimulating sound, the earliest hatching was observed when the time interval was 176 ms. Less suitable for stimulation are the time intervals 134 ms and 380 ms.

The endocannabinoid system modulates epileptic seizures by regulating neuronal excitability. It has become clear that agonist activation of central type I cannabinoid receptors (CB1R) reduces epileptogenesis in pre-clinical animal models of epilepsy. The audiogenic seizure-prone hamster GASH/Sal is a reliable experimental model of generalized tonic-clonic seizures in response to intense sound stimulation. However, no studies hitherto had investigated CB1R in the GASH/Sal. Although the distribution of CB1R has been extensively studied in mammalian brains, their distribution in the Syrian golden hamster brain also remains unknown. The objective of this research is to determine by immunohistochemistry the differential distribution of CB1R in the brains of GASH/Sal animals under seizure-free conditions, by comparing the results with wild-type Syrian hamsters as controls. CB1R in the GASH/Sal showed a wide distribution in many nuclei of the central nervous system. These patterns of CB1R-immunolabeling are practically identical between the GASH/Sal model and control animals, varying in the intensity of immunostaining in certain regions, being slightly weaker in the GASH/Sal than in the control, mainly in brain regions associated with epileptic networks. The RT-qPCR analysis confirms these results. In summary, our study provides an anatomical basis for further investigating CB1R in acute and kindling audiogenic seizure protocols in the GASH/Sal model as well as exploring CB1R activation via exogenously administered cannabinoid compounds.
