The influence of ischemia-reperfusion(I/R)action on pancreatic blood flow(pBF)and the development of acute pancreatitis(Ap)in laboratory rats is evaluated in vivo by using the laser speckle contrast imaging(LSCI).Additionally,the optical properties in norm and under condition of Ap in rats were assessed using a modied integrating sphere spectrometer and inverse Monte Carlo(IMC)software.The results of the experimental study of microcirculation of the pancreas in 82 rats in the ischemic model are presented.The data obtained conrm the fact that local ischemia and changes in the blood°ow velocity of the main vessels cause and provoke acute pancreatitis.

Sperm DNA damage is prevalent among infertile men and is known to influence natural reproduction. However, the impact of sperm DNA damage on assisted reproduction outcomes remains controversial. Here, we conducted a meta-analysis of studies on sperm DNA damage （assessed by SCSA, TUNEL, SCD, or Comet assay） and clinical pregnancy after IVF and/or ICSI treatment from MEDLINE, EMBASE, and pUBMED database searches for this analysis. We identified 41 articles （with a total of 56 studies） including 16 IVF studies, 24 ICSI studies, and 16 mixed （IVF ＋ ICSI） studies. These studies measured DNA damage （by one of four assays： 23 SCSA, 18 TUNEL, 8 SCD, and 7 Comet） and included a total of 8068 treatment cycles （3734 IVF, 2282 ICSI, and 2052 mixed IVF ＋ ICSI）. The combined OR of 1.68 （95% Ch 1.49-1.89; p 〈 0.0001） indicates that sperm DNA damage affects clinical pregnancy following IVF and/or ICSI treatment. In addition, the combined OR estimates of IVF （16 estimates, OR = 1.65; 95% CI： 1.34-2.04; p 〈 0.0001）, ICSI （24 estimates, OR = 1.31; 95% Ch 1.08-1.59; p = 0.0068）, and mixed IVF ＋ ICSI studies （16 estimates, OR = 2.37; 95% Ch 1.89-2.97; p〈 0.0001） were also statistically significant. There is sufficient evidence in the existing literature suggesting that sperm DNA damage has a negative effect on clinical pregnancy following IVF and/or ICSI treatment.

The numerical simulation of 2D simple square lattice of Ising superspins,that interact via the Ruderman–Kittel–Kasuya–Yosida(RKKY)exchange interaction is performed.It is found,that at low temperatures in the researched systems predominantly realized labyrinth domain structure.The modeled image of magnetization distribution does not coincide with the image of energy distribution.Hysteresis loops of the samples and labyrinth domain structures similarly obtained by Monte Carlo method,are also observed in physical experiments.

HIp 53731 is a binary consisting of stars of the spectral types K0 and K9.The orbit of this object was constructed previously by Cvetkovic et al.and improved by Tokovinin.It should be noted that there is a 180°ambiguity in the position angles of some published measurements.Speckle interferometric observations were obtained in 2007–2020(21 measurements)at the 6-m telescope of the SAO RAS(BTA)by the authors of this article.The analysis of new data together with previously published ones made it possible to construct an accurate orbit of HIp 53731 and to halve the already known values of the orbital period of the system.As a result of the study,the mass sum,the masses of each component and their spectral types were determined by two independent methods.According to the qualitative classification of orbits,the orbital solution has grade 2–"good"(observations cover more than half of the orbital period and correspond to different phases).

Observations by the method of lunar occultations at the 6-m telescope of the SAO RAS reach a resolution limit better than 1mas.We have devised a new method of observation,which allows obtaining the curves of lunar occultations simultaneously in different ranges of the visible part of the spectrum,and conducted the first observations using amodified optical system.In January 2019,applying the newmethod,the magnitude differences of the components of the binary star HD 36524 in the R and I bands were measured,which were 1.5 and 1.3mag,respectively,in good agreement with values calculated from the Gaia mission.According to the obtained data,it was determined that with this method it is possible to reach a signal-to-noise ratio of about 5–10 for stars of 10th magnitude.We discuss the applicability of the proposed optical scheme for the study of binary stars.

The results of a study on the binary HIp 18856 and construction of its orbit are presented.New observational data were obtained at the BTA of SAO RAS in 2007-2019.Earlier,Cvetkovic et al.constructed the orbit for this system.However,it is based on six measurements,which cover a small part of the orbit.The positional parameters of the ESA astrometric satellite Hipparcos published speckle interferometric data(Mason et al.,Balega et al.,Horch et al.)and new ones were used in this study.Based on the new orbital parameters,the mass sum was calculated and the physical parameters of the components were found.The obtained orbital and fundamental parameters were compared with the data from the study by Cvetkovic et al..The comparison shows that the new orbital solution is better than the old one,since it fits new observational data accurately.Also based on a qualitative evaluation performed by Worley&Heintz,the new orbit was classified as"reliable",which means data cover more than half of the orbit with sufficient quantities of residuals of measurements.

汉语中有关各类语法项目偏误分析的研究成果较为丰富,但是对于汉语“是”的偏误分析研究中,针对俄罗斯学生的使用偏误研究成果较少。“是”是汉语初级阶段留学生的学习项目,其形式看似容易,但用法的复杂性导致了留学生较高的使用偏误。本研究基于前人的研究成果为俄语与汉语中“是”的语法特点对比提供新的思路,同时基于实验的研究方法提出教学建议。本研究包括跟“是”相关的汉语语法项目和俄语语法项目对比:1.汉语、俄语动词“是”在语法系统分类的问题2.汉语判断动词“是”和俄语动词“быть”,“являться”的对比3.汉语、俄语表示存现意义的动词“是”对比4.汉语“是……的”结构和俄语形动词,形动词短语对比5.表示强调、“的确”意思的副词“是”和俄语副词“действительно”对比由于汉语和俄语语法系统之间差异较大,将两种语言体系统一进行对比较难,但是在对汉语动词“是”与俄语动词“быть”,“являться”,“суть”和俄语副词“действительно”进行对比研究时,我们发现这两种语言之间除了不同点有相同的地方。这些相同点不明显,所以大部分俄罗斯学生无法注意到这类特点。在两类语法点存在相同点的基础上,对汉语“是”的语法特点进行详细分析。本研究也包括偏误分析部分,偏误分析部分基于对BCC语料库资料和“是”的偏误测试结果资料的研究。本研究对这些资料进行梳理,用SpSS软件进行统计分析。在对数据统计的基础上,本研究将“是”的偏误分为四类（误加,遗漏,误代,错序）,并对偏误出现率进行分析。在偏误案例分析过程中,分析某一种偏误在何种语法项目会出现,然后试着探究偏误产生原因。本文对造成俄罗斯留学生“是”使用偏误的几类原因进行梳理,分析其中的最主要因素。通过偏误分析和对实验测试数据的分析,本文提出针对性的教学建议,以降低学生在“是”使用方面的偏误。
