Heart and metabolic diseases are very common in society today. There are many special features in their manifestation that have influence on prognosis and therapy approaches. Among them are gender characteristics. The aim of the research was to determine the gender peculiarities of disorders of lipid metabolism in patients with coronary heart disease and type 2 diabetes mellitus (T2DM). The study of the blood lipid spectrum in patients with coronary heart disease and T2DM was conducted in 72 patients aged 37 to 85 years old. The patients with coronary heart disease were divided into 2 groups depending on the presence or absence of T2DM: 1 group (n = 40) – patients with coronary heart disease only (Stable Angina Pectoris); group 2 (n = 32) – patients with coronary heart disease and T2DM. Each group was divided into subgroups depending on the gender of the patients: 1A and 2A – males, 1B and 2B – females. Despite the presence of T2DM, a majority of patients with coronary heart disease were overweight and obese. At the same time, obesity was more common in the female subgroups (1B – 45.0%, 2B – 64.7%) than in the male subgroups (1A – 35.0% and 2A – 33.3% respectively). There was an increase in the levels of total cholesterol, triglycerides and low-density lipoproteins for impaired lipid metabolism in patients with coronary heart disease. There was a slightly higher level of total cholesterol (6.12 ± 2.06 mmol/L) and low-density lipoproteins (4.24 ± 1.79 mmol/L) and a lower level of triglycerides (1.63 ± 0.65 mmol/L) in females than in males (5.15 ± 1.29, 3.71 ± 1.14 and 2.40 ± 1.06 mmol/l, respectively). Disruption of lipid metabolism was characterized predominantly by an increase in levels of triglycerides and low-density lipoproteins in blood in patients with coronary heart disease and T2DM regardless of gender. About a quarter of males (25.0% with coronary heart disease and 26.7% with coronary heart disease with T2DM) and females with T2DM (23.5%) reached the target total cholesterol level (<4.0 mmol/L), less frequently females with coronary heart disease (15.0%). The incidence of low-density lipoproteins target (<1.8 mmol/L) was significantly lower than total cholesterol: about 5.0% in males (regardless of the presence of T2DM) and 10.0% in females with coronary heart disease. Women with coronary heart disease and T2DM did not reach the target low-density lipoproteins level (<1.8 mmol/L). In most patients with coronary heart disease dyslipidemia grade II by Fredrickson was observed regardless of the presence of T2DM: in 100% of patients with coronary heart disease and 81.1% of patients with coronary heart disease and T2DM. A distinctive feature of impaired lipid metabolism in patients with coronary heart disease and T2DM is the presence in some of patients of Dyslipidemia grade IV by Fredrickson (6.7% of males and 5.9% of females) and the absence of Dyslipidemia class IIa in males in this group.

心脏病和代谢性疾病在当今社会非常常见。它们的表现有许多特殊的特点,影响预后和治疗方法。其中包括性别特征。本研究的目的是确定冠心病和2型糖尿病(T2DM)患者脂质代谢紊乱的性别特征。对72例年龄在37岁至85岁之间的冠心病和T2DM患者的血脂谱进行了研究。根据是否存在T2DM,将冠心病患者分为2组:1组(n=40)-仅患有冠心病(稳定型心绞痛)的患者;第2组(n=32)-冠心病和T2DM患者。根据患者的性别,每组被分为亚组:1A和2A——男性,1B和2B——女性。尽管存在T2DM,但大多数冠心病患者都是超重和肥胖的。与此同时,女性亚组(1B-45.0%,2B-64.7%)的肥胖率高于男性亚组(分别为1A-35.0%和2A-33.3%)。冠心病患者的总胆固醇、甘油三酯和低密度脂蛋白水平升高,导致脂质代谢受损。女性的总胆固醇水平(6.12±2.06 mmol/L)和低密度脂蛋白水平(4.24±1.79 mmol/L)略高于男性(分别为5.15±1.29、3.71±1.14和2.40±1.06 mmol/L),甘油三酯水平(1.63±0.65 mmol/L)较低。冠心病和T2DM患者(无论性别)的脂质代谢紊乱主要表现为血液中甘油三酯和低密度脂蛋白水平升高。约四分之一的男性(25.0%患有冠心病,26.7%患有冠心病伴T2DM)和女性(23.5%)达到目标总胆固醇水平(<4.0mmol/L),女性冠心病发病率较低(15.0%)。低密度脂蛋白靶点(<1.8 mmol/L)的发病率显著低于总胆固醇:男性(无论是否存在T2DM)约为5.0%,女性冠心病约为10.0%。患有冠心病和T2DM的女性没有达到目标低密度脂蛋白水平(<1.8 mmol/L)。在大多数冠心病患者中,无论是否存在T2DM,Fredrickson都观察到II级血脂异常:在100%的冠心病患者和81.1%的冠心病和T2DM患者中。冠心病和T2DM患者脂质代谢受损的一个显著特征是,Fredrickson的一些IV级血脂异常患者(6.7%的男性和5.9%的女性)存在,而该组男性中没有IIa级血脂异常。对总胆固醇和低密度脂蛋白目标水平的实现情况的分析表明,冠心病和T2DM患者没有足够的降脂治疗处方。

Determination of chlorophyll and carotenoid content is an important way of obtaining information about the plant's photosynthetic activity as well as an indirect method of assessing the productivity of plant crops, particularly grain crops. The objective of this study was to evaluate the role of chlorophyll and carotenoid in the productivity formation of emmer wheat (Triticum dicoccum (Schrank.) Schuebl) grown under the traditional and organic farming systems and the different pre-sowing seed treatment methods. The base indicators of the photosynthetic apparatus (chlorophyll and carotenoid content, ratio of photosynthetic pigments) were evaluated in the emmer wheat plants as a function of the cultivation technology and pre-sowing seed treatment. The cultivation of the emmer wheat under organic technology was carried out in crop rotation: winter rye – mustard – T. dicoccum wheat. The pre-sowing seed treatment in the traditional technology of emmer wheat cultivation was carried out only by the UV-C irradiation. In the organic technology, both UV-C irradiation and treatment with humic preparation of natural origin “1r Seed Treatment” were used. The content of chlorophyll a (by 9.2%) and chlorophyll b (by 14.5%) increased in the emmer wheat plants under the organic technology cultivation compared to the traditional technology, but with the same method of seed treatment (UV-C irradiation). As a result, the yield increase was 21.0%. The application of the “1r Seed Treatment” humic preparation in the pre-sowing seed treatment led to the increase in yield by ~ 8.0% compared to the plots with UV-C irradiation seeds treatment under organic farming cultivation. An inverse correlation between the ratio of chlorophyll a/ chlorophyll b and the crop yield has been established. The evaluation of economic indicators of the emmer wheat cultivation in the rotation: winter rye-mustard-emmer wheat under organic farming technology, proved its high profitability. So, the photosynthetic pigments’ content and their ratio can be used as the indicators of the efficiency of the introduced elements of agrotechnologies and for predicting future yields.
叶绿素和类胡萝卜素含量的测定是获得植物光合活性信息的重要途径,也是评估植物作物,特别是粮食作物生产力的间接方法。本研究的目的是评估叶绿素和类胡萝卜素在传统和有机耕作制度以及不同播前种子处理方法下生长的二粒小麦(Triticum dicocum(Schrank.)Schuebl)生产力形成中的作用。作为栽培技术和播前种子处理的函数,评估了二粒小麦植株光合器官的基本指标(叶绿素和类胡萝卜素含量、光合色素比例)。在冬黑麦-芥菜-双球菌小麦轮作中,采用有机技术栽培二粒小麦。传统小麦栽培技术中的播前处理仅采用UV-C辐射。在有机技术中,采用了UV-C辐射和天然来源的腐殖制剂“1r种子处理”处理。与传统技术相比,采用相同的种子处理方法(UV-C辐射),有机技术栽培的小麦植株叶绿素a和叶绿素b含量分别提高了9.2%和14.5%。结果,产量提高了21.0%。在有机农业种植条件下,“1r种子处理”腐殖制剂在播前种子处理中的应用使产量比UV-C辐射种子处理的地块提高了约8.0%。建立了叶绿素a/叶绿素b比值与作物产量的反相关关系。通过对冬黑麦-芥菜-二粒小麦轮作栽培经济指标的评价,证明其在有机耕作技术下具有较高的经济效益。因此,光合色素的含量及其比例可以作为农业技术引进元素效率的指标和预测未来产量的指标。

Currently, the use of nanotechnology opens up new opportunities to influence the processes of anaerobic glycolysis and the activity of hexose monophosphate reactions in preserved erythrocytes. Components containing donor red blood cells on CPDA-1 preservative were examined. Modified solutions of 0.9% NaCl and with 5% glucose were used as resuspending solutions. The solutions were treated with magnetite nanoparticles (ICNB brand) by the Belousov method. The amounts of 2,3-DPG, ATP, reduced glutathione, and glutathione peroxidase were determined by spectrophotometry. This study opens up new possibilities for increasing the shelf life and functional activity of preserved erythrocytes. The study showed a reliable increase in ATP and reduced glutathione, a decrease in 2,3-DPG and glutathione peroxidase. It was found that the activation of anaerobic glycolysis was less pronounced in tests with modified physiological saline than in tests with glucose solution. On the contrary, the pentose glucose oxidation cycle prevailed. A comprehensive analysis of the data obtained indicates the membrane-protective effect of the modified resuspending solutions. The membrane-protective effect is due to an increase in ATP and reduced glutathione, which ensures the redox potential of the cell in an equilibrium state. Magnetite nanoparticles (ICNB) change the mobility and orientation of hydrogen protons in resuspending solutions. This polarizes the aqueous sector of the erythrocyte microenvironment due to van der Waals forces, which is the main reason for activation of ATP phosphate residue hydrolysis and switching of intracellular enzymes regulating anaerobic glycolysis and pentose phosphate cycle into the active state. As a result, transmembrane metabolism and metabolism change, the energy state of erythrocytes changes, and enzymes are activated. All this has a significant impact on the energy supply of preserved red blood cells and preservation of their functional activity under storage conditions at 2 to 6 ºС.
目前,纳米技术的使用为影响厌氧糖酵解过程和保存红细胞中单磷酸己糖反应的活性开辟了新的机会。检测含有CPDA-1防腐剂的供体红细胞的成分。0.9%氯化钠和5%葡萄糖的改性溶液用作再悬浮溶液。通过Belousov方法用磁铁矿纳米颗粒(ICNB品牌)处理溶液。用分光光度法测定2,3-DPG、ATP、还原型谷胱甘肽和谷胱甘肽过氧化物酶的含量。这项研究为延长保存红细胞的保质期和功能活性开辟了新的可能性。研究表明,ATP和还原型谷胱甘肽可靠增加,2,3-DPG和谷胱甘肽过氧化物酶减少。研究发现,在用改良生理盐水的试验中,厌氧糖酵解的激活不如在用葡萄糖溶液的试验中明显。相反,戊糖-葡萄糖氧化循环占主导地位。对所得数据的综合分析表明,改性的再悬浮溶液具有膜保护作用。膜保护作用是由于ATP和还原型谷胱甘肽的增加,这确保了细胞处于平衡状态的氧化还原电位。磁铁矿纳米颗粒(ICNB)改变了氢质子在再悬浮溶液中的迁移率和取向。由于范德华力,这使红细胞微环境的水性部分极化,这是ATP磷酸残基水解激活以及调节厌氧糖酵解和戊糖磷酸循环的细胞内酶转换为活性状态的主要原因。结果,跨膜代谢和代谢发生变化,红细胞的能量状态发生变化,酶被激活。所有这些都对保存的红细胞的能量供应以及在2至6ºС的储存条件下保存其功能活性产生了重大影响。

It is known that the pathogenesis of type 2 diabetes in humans is based on two main factors – insulin resistance and inappropriate secretory activity of β-cells of the pancreas. In animals, the role of these mechanisms has not been clearly characterized, and the differences in the manifestations of experimental diabetes under the same conditions are not sufficiently substantiated. In order to study the prerequisites and mechanisms of the development of experimental type 2 diabetes or prediabetes under lipid overload, 6-month-old male Wistar rats were fed a high-fat diet for 4 weeks; after 2 weeks of the experiment, 20 or 25 mg/kg of streptozotocin was administrated. The development of insulin resistance was assessed using the insulin tolerance test. We evaluated the dynamics of glycemia in animals, subcellular signs of liver steatosis, and determined expression of the precursor and mature protein SREBP-1 by immunoblotting. It was found that in rats fed with a high-fat diet during the 2–4th weeks of the experiment, regardless of the administration of streptozotocin, stable insulin resistance and symptoms of prediabetes were detected. The severity of carbohydrate metabolism lesion, which appeared as type 2 diabetes or prediabetes after streptozotocin administration, depended on the level of hepatosteatosis due to high-fat diet, whereas the dose of streptozotocin influenced severity of type 2 diabetes. The use of a high-fat diet led to increased processing and activation of SREBP-1, which was clearly inhibited in type 2 diabetes. Therefore, the level of lipid infiltration of the liver and deregulation of the transcription factor SREBP-1 are risk factors defining development of type 2 diabetes or prediabetes in experimental rats with lipid overloading. Changes in the maturation of SREBP-1 with the use of a high-fat diet confirm that insulin resistance in rats revealed β-cell dysfunction, which closely approximates the mechanisms of experimental type 2 diabetes to main pathways in humans. At the same time, the predisposition to β-cell dysfunction can be a prerequisite that determines compensatory reserves for maintaining carbohydrate and lipid homeostasis under the influence of lipid load in both humans and laboratory animals.
众所周知,人类2型糖尿病的发病机制是基于两个主要因素——胰岛素抵抗和胰腺β细胞分泌活性不适当。在动物中,这些机制的作用还没有得到明确的表征,在相同条件下实验性糖尿病表现的差异也没有得到充分的证实。为了研究在脂质超负荷下发生实验性2型糖尿病或糖尿病前期的先决条件和机制,6个月大的雄性Wistar大鼠被喂食高脂肪饮食4周;实验2周后,给予20或25mg/kg链脲佐菌素。使用胰岛素耐受测试来评估胰岛素抵抗的发展。我们评估了动物血糖的动态、肝脂肪变性的亚细胞体征,并通过免疫印迹测定了前体和成熟蛋白SREBP-1的表达。研究发现,在实验的2-4周内,在喂食高脂肪饮食的大鼠中,无论是否服用链脲佐菌素,都能检测到稳定的胰岛素抵抗和糖尿病前期症状。链脲佐菌素给药后出现2型糖尿病或糖尿病前期的碳水化合物代谢损伤的严重程度取决于高脂饮食引起的肝脂肪变性水平,而链脲佐霉素的剂量影响2型糖尿病的严重程度。高脂肪饮食的使用导致SREBP-1的加工和激活增加,这在2型糖尿病中被明显抑制。因此,肝脏的脂质浸润水平和转录因子SREBP-1的失调是定义脂质过载实验大鼠患2型糖尿病或糖尿病前期的危险因素。使用高脂饮食后SREBP-1成熟度的变化证实,大鼠的胰岛素抵抗揭示了β细胞功能障碍,这与实验性2型糖尿病的机制与人类的主要途径非常相似。同时,β细胞功能障碍的易感性可能是决定人类和实验动物在脂质负荷影响下维持碳水化合物和脂质稳态的补偿储备的先决条件。

Resistance to antibiotics is well-known global phenomenon. There are places contributing to the development of antibiotic resistance such as waste landfills, especially ones that accept medical waste which did not undergo disinfection and livestock waste with bacteria not sensitive to antibiotics. An extensive system of transfer of antibiotic resistant microorganisms is formed on these territories (zoochory, groundwater, transport etc.). The aim of the research was to determine the species composition of bacteria isolated from birds of Derhachi municipal solid waste landfills in Kharkiv city, Ukraine. Also, we determine the sensitivity of bacterial isolates to a number of standard antibiotic drugs. We collected droppings of feral pigeons (Columba livia Gmelin, 1789; Columbidae) and starlings (Sturnus vulgaris Linnaeus, 1758; Sturnidae) during the winter period in 2020/2021; both species are dominants of waste landfills. We isolated 15 bacteria species of 4 families by bacteriological methods (growing on simple and selective media and identification by biochemical properties): Enterobacteriaceae (Enterobacter asburiae, E. dissolvens, E. cancerogenus, E. cloacae, E. sakazakii, Escherichia coli, Klebsiella terrigena, K. ornithinolytica, Citrobacter freundii, Proteus mirabilis), Yersiniaceae (Serratia ficaria, S. rubidaea, S. entomophila), Morganellaceae (Providencia stuartii) and Pseudomonadaceaе (Pseudomonas aeruginosa). Sensitivity was determined by the disk-diffusion method to 18 antibiotics. Ten isolates turned out to be multiresistant-resistant to three or more classes of antimicrobial drugs. A promising direction for future research is the determination of the pathogenicity of the isolates and checking the roles of birds of Derhachi solid waste landfills as reservoirs of pathogens. Currently, it can be assumed that large concentrations of synanthropic birds (especially those that forage on solid waste landfills) with a high probability are reservoirs of many bacteria, in particular those that have developed resistance to drugs.
抗生素耐药性是众所周知的全球性现象。有些地方助长了抗生素耐药性的发展,比如垃圾填埋场,尤其是那些接收未经消毒的医疗废物和含有对抗生素不敏感细菌的牲畜废物的地方。在这些地区(动物园、地下水、运输等)形成了广泛的抗生素抗性微生物转移系统。研究的目的是确定从乌克兰哈尔科夫市Derhachi市固体废物填埋场的鸟类中分离的细菌的物种组成。此外,我们还确定了细菌分离株对一些标准抗生素药物的敏感性。我们在2020/2021年冬季收集了野鸽(Columba livia Gmelin,1789;Columbidae)和八哥(Sturnus vulgaris Linnaeus,1758;Sturnidae)的粪便;这两个物种都是垃圾填埋场的主要物种。我们通过细菌学方法(在简单和选择性培养基上生长并通过生化特性鉴定)分离出4个科的15种细菌:肠杆菌科(asburiae肠杆菌、溶解性肠杆菌、致癌性大肠杆菌、阴沟肠杆菌、阪崎肠杆菌、大肠杆菌、terrigena克雷伯氏菌、鸟氨酸水解克雷伯菌、弗氏柠檬酸杆菌、奇异变形杆菌),耶尔森菌科(Serratia ficaria、S.rubidaea、S.昆虫学)、Morganellaceae(Providencia stuartii)和Pseudomonadaceaе(铜绿假单胞菌)。用纸片扩散法测定对18种抗生素的敏感性。10个分离株对三类或三类以上的抗微生物药物具有多重耐药性。未来研究的一个有希望的方向是确定分离物的致病性,并检查Derhachi固体废物填埋场鸟类作为病原体库的作用。目前,可以假设,大量的联鸟(尤其是那些在固体废物填埋场觅食的鸟)很可能是许多细菌的宿主,尤其是那些对药物产生耐药性的细菌。

The most difficult form of male infertility to treat is azoospermia. Azoospermia is defined as the complete absence of spermatozoa in the ejaculate. The age of the patients who underwent clinical and diagnostic studies varied between 22 and 45 years. Among 119 examined patients with azoospermia, 58.0% were diagnosed with secretory infertility. In 42.0% patients, the presence of spermatogenesis in excretory-obturational infertility was established. Among 69 patients with secretory infertility, 23 had azoospermia in the absence of spermatozoa and spermatogenic cells, which accounted for 33.3% of all patients with secretory infertility (in particular, 2 with leukocytospermia, which indicated damage to the tubular apparatus as a result of previous orchitis). In 66.6% patients, azoospermia was observed in the absence of spermatozoa, but in the presence of precursor cells of spermatogenesis. 11.5% patients out of 69 (group 1) were diagnosed with concomitant diseases. We see that arterial hypertension, diseases of the gastrointestinal tract, liver, and kidneys occur. Hereditary diseases were not detected in the examined patients. Pain of varying intensity was found in 6.7% of patients, varying degrees of testicular hypoplasia were found in 7.6%, dysuria in 13.4%, epididymitis in history 8.4%; history of epidemic mumps 6.7%; 12.6% had depression, restlessness, sleep disorders, and 21.0% had erectile dysfunction. According to clinical examination and ultrasound, chronic prostatitis is suspected in 19.2% of patients. An increase in the number of leukocytes in the blood was found in 13.2% patients. According to ultrasound, 60.5% of the patients with azoospermia had normal testicular sizes, and 39.5% had reduced testes. The volume of the testicles in the control group was 22.3 ± 2.1 cm³ on average, varying from 18.3 to 25.1 cm³. In the group with azoospermia, the volume of the testicles was on average 16.7 ± 1.7 cm³ and varied from 8.2 to 21.1 cm³, that is, the volume of the testicles in patients with azoospermia was on average 1.3 times smaller compared to normozoospermia. In the obstructive form of azoospermia, diffuse changes were detected in both testicles, probably obturational changes. Hypoplasia of the left testicle and increased echogenicity were observed in the non-obstructive form of azoospermia. The veins of the spermatic cord were moderately dilated. There was a normal amount of free fluid in the scrotum. According to elastography, the elasticity of the testicles was above normal. Obturational processes in the testicles were suspected. The hemodynamic parameters of testicular parenchymal blood flow in infertile men obtained by ultrasound dopplerography are of important diagnostic value. The average value of the linear blood flow velocity in the arteries of the parenchyma in men with normozoospermia was 0.107 ± 0.015 m/s on the right, and 0.103 ± 0.012 m/s on the left. With azoospermia, the average value of the linear velocity of blood flow on the
男性不育最难治疗的形式是无精子症。无精子症是指精液中完全没有精子。接受临床和诊断研究的患者年龄在22至45岁之间。在119例无精子症患者中,58.0%被诊断为分泌性不孕。在42.0%的患者中,排泄性闭塞性不孕中存在精子发生。在69名分泌性不孕患者中,23名患者在缺乏精子和生精细胞的情况下出现无精子症,占所有分泌性不孕病例的33.3%(尤其是2名患者患有白细胞精症,这表明先前的睾丸炎对管状器官造成了损伤)。66.6%的患者在没有精子的情况下观察到无精子症,但在有精子发生前体细胞的情况下。69例(第1组)中11.5%的患者被诊断为伴有疾病。我们看到动脉高血压、胃肠道、肝脏和肾脏疾病都会发生。在接受检查的患者中未发现遗传性疾病。6.7%的患者出现不同程度的疼痛,7.6%的患者发现不同程度的睾丸发育不全,13.4%的患者存在排尿困难,8.4%的患者有附睾病史;流行性腮腺炎病史6.7%;12.6%患有抑郁症、烦躁不安、睡眠障碍,21.0%患有勃起功能障碍。根据临床检查和超声检查,19.2%的患者怀疑患有慢性前列腺炎。13.2%的患者血液中白细胞数量增加。根据超声检查,60.5%的无精子症患者睾丸大小正常,39.5%的患者睾丸缩小。对照组的睾丸体积平均为22.3±2.1 cm³,从18.3到25.1 cm³不等。无精子症患者的睾丸体积平均为16.7±1.7 cm³,从8.2到21.1 cm³不等,也就是说,无精子病患者的睾丸容量平均是正常精子症患者的1.3倍。在梗阻性无精子症中,两个睾丸都有弥漫性变化,可能是闭塞性变化。非梗阻性无精子症患者左睾丸发育不全,回声增强。精索静脉适度扩张。阴囊内有正常量的自由液体。根据弹性成像,睾丸的弹性高于正常水平。怀疑睾丸有闭孔过程。应用超声多普勒技术检测不育男性睾丸实质血流动力学参数,具有重要的诊断价值。正常精子症男性软组织动脉中线性血流速度的平均值为0.107±0.015m/s(右侧)和0.103±0.012m/s(左侧)。无精子症患者,右侧的血流线速度平均值为0.086±0.012 m/s,左侧为0.084±0.008 m/s。因此,阴囊的血液动力学指标显示,在没有精子发生的情况下,无精子症男性的变化最为明显。

Sarcoid is one of the most common skin tumours, which is diagnosed in various breeds of horses at any age regardless of the animal’s sex. Such fibroblastic neoplasm manifests itself in several clinical ways with its specific morphological features. As a rule, it metastasizes rarely but can be locally invasive. The disease’setiology is multifactorial and includes the confirmed role of the bovine papillomavirus and genetic and environmental factors. The article introduces the results of a retrospective study of horses of the Ukrainian riding breed with a fibroblastic sarcoid type, which was localized mainly in the area of the external thoracic vein. Neoplasms were represented by two types. The first one included broad base neoplasms without a pronounced pedicle but with signs of hyperkeratosis. Massive rounded dense formations with an ulcerated surface refer to the second type. To verify the studied types of sarcoid, wide surgical excision of the lesion’svisible parts was performed, followed by the selection of fragments for the pathohistological diagnosis. Also, additional staining methods were used to detect the connective and muscle tissue (Van Gieson’s staining) and elastic fibers (Weigert’s resorcin-fuchsin staining). Microscopically, the neoplasm without a visible pedicle showed signs of hyperkeratosis and acanthosis in the peritumoral epidermal layer. Epidermis desquamation with a significant amount of oxyphilic detritus, diapedesis hemorrhages, and dilated vessels was also detected in some areas. Chaotic placement of fibroblasts and fibrocytes was noted, to a greater extent, subdermally. Anisocytosis and anisokaryosis were expressed moderately. Sarcoids, macroscopically presented in the form of massive dense formations with an ulcerated surface, were histologically characterized by the replacement of the epidermis with cellular elements, subdermal hemorrhages, and the characteristic perpendicular orientation of coarse collagen fibers towards the basement membrane. Closely spaced spindle-shaped cells with fibers forming moiré structures were visualized in the deep dermis layers. Nuclei were hyperchromic and elongated in shape, no atypical mitoses were noted. Pathohistological examination during the identification of a sarcoid type for diagnostic purposes can cause rapid growth and formation of an ulcer. The final diagnosis regarding equine sarcoid can be made based on a combination of clinical signs, histopathological examination, and molecular genetic testing with the isolation of BPV DNA.
肉瘤是一种最常见的皮肤肿瘤,在各种马的任何年龄,无论动物的性别,都可以诊断出来。这种纤维母细胞肿瘤具有多种临床表现,具有特定的形态特征。通常,它很少转移,但可以局部侵入。该病的病因是多因素的,包括牛乳头瘤病毒、遗传和环境因素的确定作用。本文介绍了一项回顾性研究的结果,乌克兰骑马品种的马与纤维母细胞肉瘤型,主要定位于胸外静脉的区域。肿瘤分为两种类型。第一种包括无明显蒂的宽基底肿瘤,但有角化过度的迹象。具有溃烂表面的大量圆形致密地层属于第二种类型。为了验证所研究的肉瘤类型,对病变可见部分进行广泛的手术切除,然后选择碎片进行病理组织学诊断。此外,采用附加染色方法检测结缔组织和肌肉组织(Van Gieson染色)和弹性纤维(Weigert的间瘤素-品红染色)。显微镜下,没有可见蒂的肿瘤显示角化过度和瘤周表皮层棘层。表皮脱屑伴大量亲氧碎屑、渗血出血及部分部位血管扩张。成纤维细胞和纤维细胞的混乱分布在很大程度上是在真皮下。细胞增多症和异核症表现中等。肉瘤,宏观上表现为块状致密结构,表面溃烂,组织学特征为表皮被细胞成分取代,真皮下出血,粗胶原纤维向基底膜垂直方向。在真皮层深层可见紧密间隔的梭形细胞,纤维形成波纹状结构。细胞核深染,形状拉长,未见非典型有丝分裂。在为诊断目的而进行的肉瘤类型鉴定过程中的病理组织学检查可导致溃疡的快速生长和形成。对马肉瘤的最终诊断可结合临床症状、组织病理学检查和分子基因检测以及BPV DNA的分离。

As the number of people on earth increases, so does the need for food. Providing the population with environmentally friendly agricultural food is one of the urgent problems of our time. Currently, the main direction of modern organic farming is the use of biofertilizers. Bacterial preparations are capable of influencing the physiological processes of plants in small quantities, leading to increase in plant productivity. The objective of this work was to study rhizobacteria associated with wheat roots. For this purpose, we took more than 100 isolates of rhizobacteria from the rhizosphere and root surface of wheat plants grown in irrigated fields of Tashkent, Syrdarya, Andijan, Kashkadarya regions. Rhizobacteria were grown on nutrient media of Döbereiner, Ashby, Pikovsky, and Zack, and 25 isolates of associative rhizobacteria were selected based on the characteristics of absorption of molecular nitrogen, mobilization of phosphorus and potassium. They actively dissolved Сa3(PO4)2 and KAlSiO4 for 3 days. They were found to produce organic acids. In organic farming, nitrogen-fixing, phosphorus- and potassium-mobilizing rhizobacteria are of great practical importance, while our experiments on obtaining biological products are considered as an environmentally friendly and cost-effective way to increase crop yields. From the surface of wheat roots grown in different zones of Uzbekistan, when screening for nitrogen fixation, we selected 3 isolates with acetylene reductase activity of 79–91 nmol C2H4/flacon/24h. We determined that bacteria completely mobilized phosphate, forming 100% acid when grown in a medium containing Ca3(PO4)2 for 5 days. The ability of the bacteria to mobilize potassium was studied on a nutrient KAlSiO4-containing medium. The bacteria were observed to mobilize potassium, forming 90–100% acid within 15 days. Based on the study of the 16S rRNA gene of bacteria, we identified rhizobacteria UT3, UT4, and UT9 as Rahnella aquatilis.
随着地球上人口的增加,对食物的需求也在增加。为人民提供环境友好的农业食品是我们这个时代的紧迫问题之一。目前,现代有机农业的主要方向是使用生物肥料。细菌制剂能够少量影响植物的生理过程,从而提高植物生产力。本研究的目的是研究与小麦根系相关的根际细菌。为此,我们从塔什干、锡尔达里亚、安集延和卡什卡达里亚地区灌溉农田中种植的小麦根际和根表面提取了100多个根际细菌分离株。根际细菌在Döbereiner、Ashby、Pikovsky和Zack的营养培养基上生长,根据分子氮的吸收、磷和钾的迁移特性,筛选出25株结合根际细菌。它们主动溶解Сa3(PO4)2和KAlSiO4 3天。人们发现它们能产生有机酸。在有机农业中,固氮、调动磷和钾的根际细菌具有非常重要的实际意义,而我们获得生物产品的实验被认为是提高作物产量的一种环保且具有成本效益的方法。从乌兹别克斯坦不同地区生长的小麦根系表面,在筛选固氮时,我们选择了3个乙炔还原酶活性为79–91 nmol C2H4/flacon/24h的分离株。我们确定,当细菌在含有Ca3(PO4)2的培养基中生长5天时,细菌完全动员磷酸盐,形成100%的酸。在含有KAlSiO4的营养培养基上研究了细菌调动钾的能力。观察到细菌能调动钾,在15天内形成90-100%的酸。基于对细菌16S rRNA基因的研究,我们将根际细菌UT3、UT4和UT9鉴定为水生拉氏菌。

Curly mallow (Malva verticillata L.) is a promising species for cultivation to obtain valuable compounds for the application in medicine, and this species can be used in the bioenergy system to provide industry with alternative energy sources. For the highest economic efficiency, the practical use of this species requires the development of complex measures related to both agrotechnologies and selective breeding. Such measures require resources and there is an urgent problem of assessing the prospects of such investments taking into account the global climate change. Therefore, the problem that we aimed to solve was the assessment of how the global climate change would impact the curly mallow in general in the global context, as well as in the conditions of Ukraine in the next 50–70 years. The database of the Global Biodiversity Information Facility (GBIF) contains 2,104 records of curly-leaved mallow. This species is found on all the continents except Antarctica. Asia accounts for 39.1% of the species’ range, Europe – 53.3%, Africa – 3.6%, North America – 3.2%, South America – 0.1%, Australia – 0.8%. The modelling of M. verticillata response to the climatic factors showed that the best response models were V (in 31.6% of cases) and VII (in 36.8% of cases). Model V characterizes unimodal bell-shaped asymmetric response, and model VII – bimodal asymmetric response. The species response to the mean annual temperature is asymmetric bell-shaped with a shift to the right. The optimal average annual temperature for this species is 9.1 °C. Comparing the distribution of available resources and their use is the basis for identifying the features of the ecological niche of the species. The MaxEnt approach indicates that Southeast Asia and Europe have the most favourable conditions for the existence of this species. Changes in the climatic conditions over the next 50–70 years will make the conditions for the life of M. verticillata in the southern hemisphere unfavourable, and the favourable conditions for it in the northern hemisphere will shift significantly to the north. At the same time, conditions in the autochthonous range of the species will become unfavourable. Obviously, if not for the significant potential of the species to disperse, it would have died out as a result of the significant climate change. The area where favourable conditions for the species will remain unchanged is Central Europe. Conditions in Eastern Europe, including Ukraine, will moderately improve. The results indicate the perspective of the cultivation of curly mallow in Ukraine in the future.
卷曲锦葵(Malva verticillata L.)是一种很有前途的栽培物种,可以获得有价值的化合物用于医学,该物种可以用于生物能源系统,为工业提供替代能源。为了获得最高的经济效益,该物种的实际使用需要制定与农业技术和选择性育种相关的复杂措施。这些措施需要资源,在考虑到全球气候变化的情况下评估这些投资的前景是一个紧迫的问题。因此,我们旨在解决的问题是评估全球气候变化将如何在全球背景下以及乌克兰未来50-70年的条件下影响卷曲锦葵。全球生物多样性信息基金(GBIF)的数据库包含2104份卷叶锦葵的记录。该物种分布于除南极洲以外的所有大陆。亚洲占该物种范围的39.1%,欧洲占53.3%,非洲占3.6%,北美占3.2%,南美占0.1%,澳大利亚占0.8%。轮藻对气候因素的反应模型显示,最佳反应模型为V(31.6%的病例)和VII(36.8%的病例)。模型V表示单峰钟形不对称响应,模型VII表示双峰不对称响应。物种对年平均温度的反应是不对称的钟形,并向右移动。该物种的最佳年平均温度为9.1°C。比较可用资源的分布及其利用是确定物种生态位特征的基础。MaxEnt方法表明,东南亚和欧洲是该物种存在的最有利条件。未来50-70年气候条件的变化将使轮藻在南半球的生活条件变得不利,而北半球对轮藻的有利条件将显著向北转移。与此同时,该物种在当地范围内的条件将变得不利。显然,如果不是因为该物种的巨大潜力分散,它就会因重大气候变化而灭绝。对该物种有利的条件将保持不变的地区是中欧。包括乌克兰在内的东欧的情况将适度改善。研究结果表明了今后在乌克兰种植卷曲锦葵的前景。

Imidacloprid is one of the most widely used insecticides in the world. The neurotoxicity of imidacloprid in adult amphibians has not been studied thoroughly. We investigated the expression of glial fibrillary acidic protein (GFAP), neurofilament light chain (NfL) and angiostatin in the amphibian brain to identify valid biomarkers of low dose imidacloprid exposure. For the experiment, 30 individuals of the marsh frog Pelophylax ridibundus were selected. The amphibians were divided into five groups. The duration of the experiment was 7 and 21 days. The exposure concentrations were 10 and 100 µg/L. The results of the study revealed a decrease in the expression of GFAP after 7 days in the exposure groups of 10 and 100 μg/L. An increase in the level of NfL was observed in the group exposed to 10 μg/L after 21 days of the experiment. The angiostatin level was increased after 7 days at 10 µg/L and after 21 days at 100 µg/L. The data obtained indicate that low concentrations of imidacloprid can cause neurotoxic effects in the brain of P. ridibundus. Such effects can have a significant impact on amphibian populations. According to the results of the study of the expression level of GFAP, NfL and angiostatin, it can be stated that imidacloprid has a neurotoxic effect on adult marsh frogs. The studied indicators can be promising biomarkers of environmental pollution by neonicotinoids.
吡虫啉是世界上使用最广泛的杀虫剂之一。吡虫啉对成年两栖动物的神经毒性尚未得到彻底研究。我们研究了两栖动物大脑中胶质纤维酸性蛋白(GFAP)、神经丝轻链(NfL)和血管抑素的表达,以确定低剂量吡虫啉暴露的有效生物标志物。为了进行实验,选择了30只蛙。两栖动物被分为五组。实验持续时间分别为7天和21天。暴露浓度分别为10和100µg/L。研究结果显示,10和100μg/L暴露组的GFAP表达在7天后降低。实验21天后,在暴露于10μg/L的组中观察到NfL水平增加。10µg/L的血管抑素水平在7天后和100µg/L的21天后升高。所获得的数据表明,低浓度的吡虫啉会对啶虫的大脑产生神经毒性作用。这种影响会对两栖动物种群产生重大影响。根据GFAP、NfL和血管抑素表达水平的研究结果,吡虫啉对成年沼泽蛙具有神经毒性作用。所研究的指标可以成为新烟碱类环境污染的有前景的生物标志物。
