L.S. Vygotsky and the Theater

The article presents the analysis of L.S. Vygotsky's works dedicated to the theater arts and is organized according Vygotsky's different life and work stages. Meanwhile special attention is paid to the Gomel period during which a large number of reviews were written by Vygotsky and published in “Nash ponedel'nik” and “Polesskaia pravda” newspapers. Biographical facts are widely used in this analysis and help to clarify Vygotsky's interest in art. It is shown that even at the beginning of his oeuvre, he was interested not only in a range of problems in art, but also psychological problems related to art perception and creativeness. Vygotsky's usage of structural concept ideas about the peculiar properties of literary text composition are also explored. Vygotsky analyzes the socio-psychological mechanisms of theatrical art effect. Furthermore, those areas which are widely used by Vygotsky in determining the characteristics of cast reincarnation are examined. Special emphasis is placed on the different elements of the actor techniques (speech, movement, emotional expression, acting personality and etc.). Materials are widely used in this study and help identify the socio-cultural context that defined Vygotsky's values at different stages of his work, related to his drama criticism and his formation as a professional psychologist.     

TK1与LDH联合检测对非霍奇金淋巴瘤鉴别诊断及疗效评估的作用

目的:探讨联合检测血清胸苷激酶1(TK1)与乳酸脱氢酶(LDH)水平在非霍奇金淋巴瘤(NHL)患者鉴别诊断及疗效监测中的临床意义。方法:收集2016年1月至2018年6月我院诊治的111例非霍奇金淋巴瘤的初诊患者血清标本,并选择50例正常人血清标本作为对照,采用免疫印迹增强发光法检测TK1浓度,比色法检测LDH浓度。所有患者随访至少1年,分析和比较惰性NHL与侵袭性NHL及各自四类分期之间血清TK1和LDH水平的差异,化疗后完全缓解、部分缓解与未缓解组LDH水平以及NHL患者中血清TK1和LDH的阳性率。结果:高度侵袭性NHL患者和侵袭性NHL患者血清TKI和LDH水平与惰性NHL患者相比显著增高(P0.05),但惰性NHL患者血清TK1和LDH水平与正常组之间差异无统计学意义(P0.05);Ⅲ、Ⅳ期侵袭性NHL患者血清TK1和LDH水平与Ⅰ、Ⅱ期患者相比显著增高(P0.05)。与化疗前相比,四次化疗后,完全缓解组NHL患者血清LDH水平下降21.05%,部分缓解组为16.66%,病情稳定组血清LDH水平升高至11.54%,三组NHL患者血清LDH水平比较差异具有统计学意义(P0.008),两组之间的差异均有统计学意义(P0.05)。结论:联合检测血清TK1和LDH水平对于NHL患者的鉴别诊断、疗效评估均具有重要参考价值。     

Physiological dynamics,reproduction‐maintenance allocations,and life history evolution

Allocation of resources to competing processes of growth, maintenance, or reproduction is arguably a key process driving the physiology of life history trade‐offs and has been shown to affect immune defenses, the evolution of aging, and the evolutionary ecology of offspring quality. Here, we develop a framework to investigate the evolutionary consequences of physiological dynamics by developing theory linking reproductive cell dynamics and components of fitness associated with costly resource allocation decisions to broader life history consequences. We scale these reproductive cell allocation decisions to population‐level survival and fecundity using a life history approach and explore the effects of investment in reproduction or tissue‐specific repair (somatic or reproductive) on the force of selection, reproductive effort, and resource allocation decisions. At the cellular level, we show that investment in protecting reproductive cells increases fitness when reproductive cell maturation rate is high or reproductive cell death is high. At the population level, life history fitness measures show that cellular protection increases reproductive value by differential investment in somatic or reproductive cells and the optimal allocation of resources to reproduction is moulded by this level of investment. Our model provides a framework to understand the evolutionary consequences of physiological processes underlying trade‐offs and highlights the insights to be gained from considering fitness at multiple levels, from cell dynamics through to population growth.     

Glucose repression over Saccharomyces cerevisiae glycerol/H+ symporter gene STL1 is overcome by high temperature

High temperature promotes an improved activity of the Saccharomyces cerevisiae glycerol/H(+) symporter encoded by STL1, which correlates well with Stl1p levels. This happens in both fermentable and respiratory metabolic growth conditions, though the induction in the latter is much higher. The relief of glucose repression by high temperature at the level of protein expression and activity (Stl1p) is reported for the first time. We reason that the glycerol internal levels fine-tuning, under heat-stress as in other physiological condition, can be achieved with the contribution of the tight regulation of the symporter.     

Temperature-dependent development of Xyleborus fornicatus （Coleoptera： Scolytidae）, the shot-hole borer of tea in Sri Lanka： Implications for distribution and abundance

The effect of temperature on the rate of development of Xyleborus fornicatus （Eichh.） was determined by rearing individuals under a range of constant temperatures （15 - 32℃）. Rates of development changed in a linear fashion over a wide range of temperatures. Estimates of lower development thresholds were obtained for eggs （15.7±0.5℃）, larvae （15.8±0.8℃） and pupae （14.3±1.4℃） and the degree days （DD） for development were 70±4.4, 95±8.5 and 72±5.1 DD, respectively. Optimum temperature for development was around 30~C for all stages. Temperature fluctuation in cooler High Country areas （above 1400 m） with a mean temperature around 15℃ seems to be critical for the development of the pest, which may be responsible for the near absence of pest in those areas. Temperature fluctuations （18- 30℃） in the Mid Country region （600- 1200 m） favor the development of the pest compared to development under constant conditions. The altitudinal distribution of the shot-hole borer across tea growing areas in Sri Lanka is, therefore, mainly governed by temperature.     

Screening of fluoride analysis as a biochemical parameter in the orthodontic treatment using fixed appliances

Saliva is a critical and useful biological fluid necessary for good health and for the appropriate execution of mouth activities. Orthodontic biomaterials have a complex relationship with many components, including the oral environment. Treatment with fixed orthodontic appliances may causes dental caries. As a result, it is necessary to comprehend how orthodontic therapy and various fluoride regimens affect the chances of developing dental cavities as well as individual risk factors. Usage of fluoride will tend to reduce the caries in the patients diagnosed with the fixed orthodontic treatment. The aim of this study was to screen the biochemical parameter of the fluoride levels in the patients undergone and completed the treatment of orthodontic fixed appliances. In this study, 35 patients have been visited on day 1 as well as day 35 and categorized as T₀ and T₁ groups. Saliva samples were collected and fluoride levels were measured between T₀ and T₁ groups. Using the fluoride kit with the spectrophotometer, fluoride levels were measured. The results confirmed similar fluoride levels between T₀ (26.11 ± 4.86) and T₁ (27.71 ± 4.40) groups. There was no significant association observed in this study (p = 0.56). Fluoride might have no role in the patients undergoing orthodontic treatment.

Distribution,degree of damage and risk of spread of Trioza erytreae (Hemiptera: Triozidae) in Kenya

The African citrus triozid (ACT), Trioza erytreae Del Guercio, is a destructive pest particularly on citrus, and vectors, “Candidatus” Liberibacter africanus (CLaf), which is the causal agent of the African citrus greening disease. Our study seeks to establish the distribution and host‐plant relationship of ACT across citrus production areas in Kenya. We also modelled the risk of spread using the maximum entropy modelling algorithm with known occurrence data. Our results infer that ACT is widely distributed and causes severe damage to four alternative host plants belonging to the family Rutaceae. The adults, immature stages (eggs and nymphs), galls and the percentage of infested leaves were significantly higher in shaded than unshaded trees. However, adult ACTs preferred Kenyan highlands to Victoria Lake and coastal regions. The average area under the curve of the model predictions was 0.97, indicating an optimal model performance. The environmental variables that most influenced the prediction were the precipitation of wettest quarter, precipitation of wettest month, mean diurnal range, temperature seasonality and mean temperature of the coldest quarter. The current prediction of ACT exceeded its existing range, especially in the Western, Nyanza, Central, Rift valley and Eastern regions of Kenya. The model predicted a contraction of suitable habitats for a potential spread in 2040 with an inland shift to higher altitudes in the cooler regions. The potential for further expansion to climatically suitable areas was more pronounced for the 2080 forecast. These findings provide relevant information to improve monitoring/surveillance and designing IPM strategies to limit its spread and damage.
