In this work, we have studied the impact of various stages of cryopreservation by vitrification in ethylene glycolsucrose medium on plasma membranes adhesive properties of 8-cell murine embryos and their specific electrical conductivity. Embryos were divided into the following experimental groups: the control, group 1 (incubation in vitrification medium) and group 2 (complete cycle of cryopreservation). The embryo exposure to vitrification medium did not affect their ability to cell-to-cell adhesion. After a complete cycle of cryopreservation, no embryo adhesion was observed. Electrical conductivity of embryo membranes was determined using the pulsed conductometry. After incubation in vitrification medium, their resistance to electric pulse was shown to decrease, that was manifested in the phenomenon of irreversible electric breakdown. The average values of electrical conductivity varied within the following ranges: ((12.1 ± 1.5)...(55.5 ± 2.6)), ((28.7 ± 5.7)...(44.± 8.9)), ((31.0 ± 9.3)...(87.9 ± 26.1)) μS/cm in the control, groups 1 and 2, respectively. These findings may be explained by appearance of first structural disorders in lipid bilayer of embryo membranes even at the stage of their incubation in vitrification medium. The lack of adhesive properties of blastomeres after vitrification-warming testified to a damage to the membrane adhesion proteins.
在这项工作中,我们研究了在乙烯-乙醇蔗糖培养基中玻璃化冷冻保存的不同阶段对8细胞小鼠胚胎质膜粘附性能及其比电导率的影响。胚胎分为以下实验组:对照组、第1组(玻璃化培养基中孵育)和第2组(冷冻保存完整周期)。胚胎暴露于玻璃化培养基不会影响其细胞间粘附的能力。经过一个完整的冷冻保存周期后,没有观察到胚胎粘附。用脉冲电导法测定胚胎膜的电导率。在玻璃化培养基中培养后,它们对电脉冲的电阻降低,表现为不可逆的电击穿现象。对照组1和2的电导率平均值分别在以下范围内变化:(12.1±1.5)…(55.5±2.6))、(28.7±5.7)…(44.±8.9)、(31.0±9.3)…(87.9±26.1))μS/cm。这些发现可以通过胚胎膜脂质双层中首次出现结构紊乱来解释,即使在胚胎膜在玻璃化培养基中孵育的阶段也是如此。玻璃化加温后卵裂球缺乏粘附特性,证明膜粘附蛋白受损。

Cardioprotective Effect of Low Molecular Weight (Below 5 kDa) Fraction of Cattle Cord Blood Cryohemolysate 牛脐血冷冻溶血液低分子量(5kDa以下)组分的心脏保护作用
Q4 Medicine Pub Date : 2022-09-30 DOI: 10.15407/cryo32.03.206

In this report, we have studied a cardioprotective effect of low molecular weight (below 5 kDa) fraction derived from cattle cord blood in a rat model of infarction-like cardiovasopathy. The myocardial infarction development was initiated in the animals, maintained for two months on a diet with excessive intake of fat, calcium and sodium salts, by making hypoxia-hypercapnia in them. The use of this model allowed inducing the infarction-like cardiovasopathy, comparable by many respects with the clinical picture of myocardial infarction, which was confirmed by electrocardiography, enzyme-linked immunosorbent assay and histological analysis. Preliminary administration of low molecular weight (below 5 kDa) fraction of cattle cord blood, as well as Actovegin did not prevent the heart attack, but increased the endurance of rats to hypoxia-hypercapnia and reduced the damage rate to myocardium. A preventive administration of low molecular weight fraction of cord blood was proven to mitigate the risk of hypoxia-induced damages to myocardium.
在本报告中,我们研究了从牛脐带血中提取的低分子量(低于5kDa)组分在梗死样心血管病大鼠模型中的心脏保护作用。心肌梗死的发生始于动物,通过使其缺氧高碳酸血症,在摄入过量脂肪、钙和钠盐的饮食中维持两个月。该模型的使用可以诱导类似梗死的心血管病,在许多方面与心肌梗死的临床表现相当,心电图、酶联免疫吸附测定和组织学分析证实了这一点。牛脐血低分子量(低于5kDa)组分以及Actovegin的初步给药并不能预防心脏病发作,但能提高大鼠对缺氧高碳酸血症的耐受性,降低心肌损伤率。脐血低分子量组分的预防性给药已被证明可以减轻缺氧诱导的心肌损伤的风险。

Here, we have studied the rehabilitation efficiency for patients with spinal degenerative joint diseases using the wholebody extreme air cryotherapy (WBEACT) according to our own technique. The assessment of pain intensity on visual-analogue scale upon completing the rehabilitation therapy showed the pain disappearance in 68.4% of patients, and its significant reduction in 31.6%; increased daily motor activity, and decreased restrictions during walking in 90.8% of cases; improved well-being in 35.7%; enhanced activity in 43.9%, and mood change in 38.8%. Each WBEACT session increased the muscle strength and endurance for both genders of patients, thus testifying to a stimulating effect of cryotherapy to human body. The WBEACT application for rehabilitation of patients with spinal degenerative joint diseases enabled to normalize the psycho-emotional state as quickly as possible and improve functional state of neuromuscular apparatus, i. e. to reduce the pain and muscle tonic syndromes, strengthen the muscular skeleton, and increase the range of motion and endurance while standing, sitting and walking.
在这里,我们根据自己的技术,研究了全身极限空气冷冻疗法(WBEACT)对脊柱退行性关节疾病患者的康复效果。康复治疗完成后疼痛强度视觉模拟量表评估显示,68.4%的患者疼痛消失,31.6%的患者疼痛明显减轻;90.8%的病例增加了日常运动活动,减少了行走时的限制;改善幸福感的占35.7%;43.9%的人活动增强,38.8%的人情绪改变。每次WBEACT都增加了男女患者的肌肉力量和耐力,从而证明了冷冻疗法对人体的刺激作用。将WBEACT应用于脊柱退行性关节疾病患者的康复治疗,可以使患者的心理情绪状态尽快正常化,改善神经肌肉器官的功能状态,即减轻疼痛和肌肉紧张性综合征,增强肌肉骨骼,增加站、坐、行时的活动范围和耐力。

In this work, we have studied the impact of ozonation, freezing down to liquid nitrogen temperature and their combination on sowing quality and crop yield for Dii cultivar beetroot seeds. The optimal moisture, ozone dose within the ozone-air mixture, and the exposure time, not reducing the germination rate, were determined. The ozonation, freezing, and their combined effect affected neither the seed germination in laboratory, nor biometric indices in a field. The seed freezing down to liquid nitrogen temperature was found to significantly increase its crop yield. Biochemical analysis of root crops showed all the ways of presowing treatment to reduce the content of total sugars and betanine. After freezing and ozonation, the amount of dry matter decreased, but after combined exposure it augmented. Ozonation and subsequent freezing lowered the content of ascorbic acid. Significantly reduced studied parameters did not reach the minimum values specific to this crop. Freezing and a combined impact of the studied factors on the seeds increased the nitrate content in root crops, which did not exceed the maximum allowable rate.
本研究研究了臭氧化、冷冻降至液氮温度及其组合处理对Dii品种甜菜根种子播种品质和产量的影响。在不降低发芽率的前提下,确定了臭氧-空气混合物的最佳湿度、臭氧剂量和暴露时间。臭氧化、冷冻及其综合作用对实验室种子萌发和田间生物特征指标均无影响。将种子冷冻至液氮温度可显著提高其产量。根茎作物的生化分析表明,播前处理可降低总糖和甜菜碱的含量。经冷冻和臭氧化处理后,干物质含量降低,但经复合暴露后,干物质含量增加。臭氧化和随后的冷冻降低了抗坏血酸的含量。显著降低的研究参数未达到该作物特有的最小值。冻害及多种因素对种子的综合影响使块根作物的硝酸盐含量增加,但未超过最大允许值。

Here, we have presented the data describing the cryopreservation impact on DNA status of domestic and farm animal sperm, and outlined the main causes of DNA fragmentation and methods of its detection and DNA integrity preservation. The current methods to identify the DNA fragmentation rate have been shown to be quite efficient, but the choice for the optimal way is stipulated by animal species. The oxidative stress caused by an increased content of reactive oxygen species was recognized as the main mechanism in DNA cryodamage. To prevent this negative effect on germ genetic material, many protective media and rehabilitation solutions supplemented with antioxidants (non-enzymatic, enzymatic compounds and nanoparticles) have been developed. Thus, determining the sperm DNA fragmentation rate and maintaining its integrity are the necessary steps to improve the efficiency of domestic animal gamete cryopreservation as a part of reproductive technologies.
本文介绍了低温保存对家畜和农场动物精子DNA状态影响的数据,概述了DNA断裂的主要原因以及检测和保存DNA完整性的方法。目前鉴定DNA断裂率的方法已被证明是相当有效的,但最佳方法的选择是由动物物种规定的。活性氧含量增加引起的氧化应激是DNA低温损伤的主要机制。为了防止这种对细菌遗传物质的负面影响,已经开发了许多含有抗氧化剂(非酶、酶化合物和纳米颗粒)的保护介质和修复溶液。因此,确定精子DNA的破碎率并保持其完整性是提高家畜配子冷冻保存效率的必要步骤。

The paper presents the findings on the impact of cold exposure at 4°C on chlorophylogenesis, hemogenesis and rhizogenesis in callus culture of winter wheat cultivars. The patterns of morphogenesis in the soft winter wheat in vitro culture during exposure to positive low temperature of various durations (15, 30 and 45 days) have been established. The callus culture of 2–3 passages of cv. Doridna, Statna and Astet was used. The results of experiments showed the preliminary vernalization of calluses for 30 and 45 days to strongly stimulate the chlorophylogenesis and hemogenesis, thereby increasing the frequency of obtaining the regenerant plants during further cultivation. The efficiency of these processes depended on the original cultivar genotype and cold treatment duration. The vernalization, associated with the VRN genes expression, manifested in morphogenesis change, was assumed to occur in the soft winter wheat in vitro culture.
本文介绍了4℃低温处理对冬小麦愈伤组织培养过程中叶绿素发生、血液发生和根系发生的影响。研究了软质冬小麦在不同低温条件下(15、30和45 d)的形态发生规律。对2 ~ 3代的愈伤组织进行培养。使用了Doridna, Statna和Astet。实验结果表明,愈伤组织春化期为30和45 d,能强烈促进叶绿素生成和血液生成,从而增加了进一步培养中获得再生植株的频率。这些处理的效率取决于原品种的基因型和冷处理时间。春化与VRN基因的表达有关,表现为形态发生的变化,被认为发生在软质冬小麦离体培养中。
