This article describes the hybrid of Oshima I2N2 (Morus bombycis Koidz.) × SANIISH-25 (Morus multicaulis Perr.), Obtained by
crossbreeding of mulberry tree, which is widely used in production in Uzbekistan. The specificity of the variety and the development of each clone were studied in the process of different effects on the growth and development of mulberry in standard nutrient media in vitro from the selected Jarariq 9 varieties. Our study found that when we planted 3 clones in a new environment, leaving one joint, the third apical part grew better than the 2nd medium clone, but the 3rd clone growth and root rate, which was cut close to the 3rd nutrient medium, was higher than the 1st and 2nd clones
In the practice of modem dentistry, due to the increased aesthetic requirements, one of the factors that determine the success of prosthetics with all-ceramic, metal-ceramic, zirconium dioxide orthopedic structures is the correct and accurate determination of the color of the teeth and the reconstruction of its anatomical shape and function according to the age of the patient.
This allows achieving high aesthetic quality of orthopedic constructions and reducing the incidence of expensive re-prosthetics.
The teeth color is determined by the dentin, with translucent enamel, which is playing a lesser role through scattering at wavelengths in the blue range [3]. It was reported that: shade selection is a crucial clinical step during prosthetic treatment [4]. During the visual teeth color determination it is suggested that the first impression is frequently the best match, and shade matching trials should be limited to 5 seconds at a time to prevent eye fatigue, because the vision pigment is used up quickly in the mechanism of color perception. Many times in the dental literature has been given the recommendation to relax the eyes by observing a blue card between two shade matching trials (because blue and yellow arc complementary colors) [5].
An adequate analysis of the shade of the teeth, as well as the reproduction of their color in order to maximize the imitation of the natural appearance, is one of the most difficult tasks of practical dentistry in the rehabilitation of patients using different types of restorations.
Shade matching systems continue to evolve, but so far none of them can provide a sufficiently objective result.
Various protocols for the analysis of tooth color have been known on the market for many years, but most of them provide efficiency only for the chewing group of teeth, or only for the initial analysis of the aesthetics of the frontal region, based on the parameters of photographs and modifications of the algorithms for their visualization and processing. The Vita company also introduced the Vita EASYSHADE® spectrophotometer for tooth shade matching. Shade evaluation with the spectrophotometer used in that study showed a high degree of correlation with visual shade determination of the color of natural teeth . The oldest color system was created by Albert H. Munscll in 1905. Consists from three attributes—hue (H), value or lightness (V) and chroma (C), denoted as H/V/C. Value/Lightness is the quantity of light reflected by an object compared to a pure white diffuser (reflecting 100%), and a black absorber (absorbing all incident light with no reflection). If a material reflects most of the light falling on its surface, it appears bright, i.e. it has a high value. Towards the center of the color wheel, no hue dominates and becomes less and less saturated [ 1 ]. Hue is described with the words we normally think of as describing color: red, purple, blue, etc. It is also a term which describes a dimension of color we readily experience when we look at color.
The action of many factors complicates the process of objectifying the color analysis of teeth and its reproduction. These are the different illumination of the area of interest, which distorts the color perception effect of the final restorations, the use of aesthetic materials of different quality, and the individual difference in color perception among people participating in dental treatment.The factor of the latter is also influenced by what kind of shade matching system each of the participants in the rehabilitation process uses. In addition, it should be borne in mind that the complex morphology of the tooth, its shape, surface texture, as well as the corresponding shine - all these are parameters that cannot be ignored in the process of treating any tooth.

Нами проведено ретроспективное исследование 75 случаев течения беременности и родов у женщин с ожирением, которые были разделены на 2 группы: 1 группа – 45 беременных с ожирением и 2 группа – 30 беременных с избыточной массой тела. Контрольную группу составили 16 здоровых беременных с нормальными масса ростовыми показателями. Изучено влияние избыточной массы тела и ожирения у женщин на течение и исход беременности и родов. У беременных с ожирением риск развития гипертензивных состояний возрастает в 3,5 раза. Гестационная гипертензия выявлена у 15,5%, а преэклампсия у 26,6% беременных с ожирением. Гестационный пиелонефрит выявлен у 20% 1-группы и у 10% беременных 2-группы. У женщин 1-й группы в 22% случаев беременность прервалась в сроке до 12 недель. Физиологические роды у пациенток 1-группы протекали в 68,5% случаях, а во 2-группе они составили 80%. Изучение антропометрических данных новорожденных показало, что 28,5% имели повышенную массу тела, а 25,7% новорожденных имели показатели крупного плода.
There is no difference in performance in systems with plus and minus selection. In the F-1 and F-3 systems where viability plus selection
was performed, cocoon weight values were 1.84 g and 1.85 g, and shell weights were 432 mg and 422 mg, respectively. In practice, the minus selection does not differ from those of the conducted F-2 and F-4 systems-1.72 g and 1.85 g, respectively; 394 mg and 420 mg. Clearly, the choice of viability leads to the accumulation of recessive hemispheric and subletal genes in the homozygous state in the system. As a result, some organisms die at different stages of development. But some of them survive. Probably on the one hand, because harmful genes are less accumulated, and on the other hand, because there are enough positive genes to compensate for the
effects of harmful genes, i.e., the GCC is formed. Had this process not taken place, no doubt the system would have perished as a result of negative selection over several generations. It follows that GCC does not occur in systems with high viability. The predominance of
positive genes over negative genes is achieved without them. In addition, the process of mutation is accelerated under the influence of negative selection.
Thus, not only the reserve but also the newly emerging genes remainthe source for the blocks of both categoriesThis increases gene diversity
