Morphological investigations on anthers and pollen grains of some quince cultivars

In the present study we investigated some pollen morphological characters and anther size of Cydonia oblonga. Anthers of cultivars with apple- vs. pear-shaped fruits were also compared. In 2005 the anthers of cultivars with oblate vs. suboblate pollen showed significant differences. Anthers of the oblate group were notably shorter and smaller in size, than those of the suboblate group. Equatorial area of pollen in the former group was also smaller. In 2006 P/E ratio of pollen also correlated with length, width and size of anthers. However, shape and size of pollen grains did not show any relationship in the latter year. Equatorial area of pollen grains was not connected with anther size in 2005-2006. Fruit shape correlated with pollen shape only in 2005. P/E ratio of pollen in cultivars with apple-shaped fruits was lower than in cultivars with pear-shaped fruits. We could not demonstrate any relationships between anther morphology and fruit shape of the investigated quince cultivars

Examination of DON-toxin content of milling byproduct generated after color sorting

Thanks to the favorable impact of vintage effect occurring in recent years the Fusarium contamination of wheat and consequently a high DON-toxin concentration is often caused problem. The DON-toxin in terms of human and animal health is a serious food safety risk factor. Therefore, it is important that there are methods during the wheat milling process which reduces the level of toxin. We confirmed in our earlier examinations, that with the help of modern color sorting machine the DON-toxin content of wheat items is effectively can be reduced. The question is, during the process how parallel changes the mycotoxin content of by-products, which are used primarily as animal forage. The authors are presented an analysis of these relevant experimental data. The results show, that the toxin content of the by-product is exceeds the starting wheat item's toxin content. However, the result of the regression analysis shows that no correlation in the toxin contents between the starting raw material, purified wheat and by-product. This should be considered to the users when they would like to utilize the by-product as ingredient of forage or feedstuff

Levodopa/carbidopa intesztinális gél alkalmazása előrehaladott Parkinson-kórban.

Parkinson's disease is the second most common neurodegenerative disorder around the world. Levodopa has remained the "gold standard" of the therapy even several decades after its introduction. Chronic levodopa treatment is associated with the development of motor complications in most patients. Advanced Parkinson's disease is characterized by these complications: motor and non-motor fluctuation and disturbing dyskinesia. Continuous dopaminergic stimulation might reduce these complications. In advanced Parkinson's disease levodopa is still effective. In the treatment of this stage there are several advanced or device-aided therapies: apomorphine pump, deep brain stimulation and levodopa/carbidopa intestinal gel. Levodopa/carbidopa intestinal gel is an aqueous gel that can be delivered to the jejunum via a percutaneous gastrojejunostomy tube which is connected to an infusion pump dosing the levodopa gel continuously to the place of absorption. Levodopa/carbidopa gel infusion can be used as monotherapy, can be tested, can be used individually and this therapy is reversible. Several clinical trials demonstrated that levodopa/carbidopa intestinal gel therapy is of long-term benefit, improves the quality of life of the patients and can reduce motor fluctuation and dyskinesia

Don, F-2 and T-2 mycotoxin assay of plant-based feedstock raw materials using the ELISA method

In our study, plant-based raw materials, used for feeding different animal species, are investigated, using a competitive ELISA method. The raw materials most commonly used for feeding (soy and alfalfa pellets, as well as wheat, barley and maize) were used in the tests. Of Fusarium mycotoxins, deoxynivalenol (DON), zearalenone (F-2) and T-2 toxins were measured. Measurement results were evaluated using the mathematical- statistical program RStudio. In our experiment, we found that all three mycotoxins tested could be detected in all of the samples, but the values were not quantifiable with acceptable precision in each case. The average detected DON toxin result was an order of magnitude greater than the results of the other toxins. It has been shown in our study that the presence of the mycotoxins deoxynivalenol, zearalenone and T-2 poses a serious food and feed safety risk, since they are present in feedstock raw materials, even though only in small amounts. Today, these mycotoxins are present together in more and more cases, greatly increasing the above-mentioned risk
