The MPC1 gene is involved in the transport of pyruvate into mitochondria, playing an important role in metabolic processes. Recently, it has been reported that higher MPC1 expression correlates with an increased number of immune cells in human cervical and lung cancers, indicating an enhanced antitumor immune response. Reduced MPC1 levels in gastric tumors are associated with a more severe disease course. Correlational analysis of the MPC1 gene in human lung, hippocampus and frontal cortex tissue samples based on data from the GTEx database revealed associations of this gene with schizophrenia, non-small cell lung cancer, and immune diseases. Our experiments showed that the mRNA level of the MPC1 gene in the non-small cell lung cancer cell line A549 increases 5-fold under the influence of the schizophrenia neuroleptic thioridazine. The observed elevation of MPC1 level may cause tumor infiltration by immune cells, complementing the previously reported data indicating the ability of thioridazine to slow cell growth, induce apoptosis and reduce the ability of cells to migrate.

Characteristic patterns of UV-induced skin autofluorescence were determined for patients with Parkinson's disease (PD) and associated with dysmetabolic alterations, such as nonenzymatic protein glycation, an increase in extracellular matrix stiffness, impaired metabolism of tissue fluorophores, mitochondrial dysfunction, and accumulation of aberrant proteins. Key differences in skin autofluorescence spectra were for the first time observed in PD, making it possible to discriminate between PD patients and healthy persons or individuals without signs of chronic neurodegeneration. Namely, skin fluorescence related to the reflected signal upon excitation with UV light at 375 nm was lower in PD patients.

Expression of 11 genes of the Hox cluster (SiHox1, 2, 3, 5, 6, 7, 8, 9/10, 11/13a, 11/13b, and 11/13c) was assessed in the sea urchin Strongylocentrotus intermedius at early developmental stages, including the blastula (13 h post fertilization (hpf)), gastrula (35 hpf), prism (46 hpf), and pluteus (4 and 9 days post fertilization (dpf)) stages. Expression of SiHox7, 11/13b, and 11/13c was observed at the blastula stage; early activation of 11/13c was detected for the first time in regular sea urchins. The expression level was very low at the gastrula and prism stages. The pluteus stage showed a significant increase in expression of all Hox cluster genes. Deviations from temporal collinearity of Hox gene expression in echinoderms are discussed.

Most nudibranchs feed on hydroids and anemones and utilize kleptocnidae, which are stinging capsules stolen from eaten victims, for their own defense. The nudibranch Coryphella trophina (Bergh, 1890) was found to eat other nudibranchs. Stinging capsules that the predator uses for its defense have been stolen twice: first by mollusks feeding on cnidarians and then by C. trophina eating the mollusks.

Poloxamer 188 (P188) was tested for effect on medullary hematopoiesis in aplastic anemia. P188 was administered to CBA mice with developing anemia via oral gavage at doses of 10, 100, and 500 mg/kg. A dose-dependent effect was observed, including an increase in erythrocyte count, hemoglobin, and reticulocyte count. The parameters remained low and suggested mild anemia on day 21 in a group treated with carboplatin. P188 was assumed to exert a beneficial effect on the blood cell composition, which is distorted by cytostatic drugs.

The total lipid (TL) and fatty acid (FA) contents in tissues and body segments were studied in adult Antarctic krill (Euphausia superba) caught in three regions of the Atlantic sector of Antarctica with different environmental conditions. Significant differences in lipid and FA status of the Antarctic krill tissues and body segments were observed in the regions. Main metabolic indices indicating quality of lipids showed that E. superba has a high nutritional value. In particular, lipids are highly unsaturated in the species and ratios of physiologically significant and essential FAs are favorable to human health. This was assumed to be a distinctive biochemical characteristic of the species. Data from the study can be used to form a scientifically based approach to further technological processing of raw krill and targeted extraction of certain substances and components of a lipid nature.

研究了在环境条件不同的南极洲大西洋部分三个区域捕获的成年南极磷虾(Euphausia superba)组织和体节中的总脂质(TL)和脂肪酸(FA)含量。观察到不同地区的南极磷虾组织和体节的脂质和脂肪酸状况存在显著差异。表明脂质质量的主要代谢指数显示,南极磷虾具有很高的营养价值。特别是,该物种的脂质高度不饱和,具有重要生理意义的必需脂肪酸比例对人体健康有利。这被认为是该物种独特的生化特征。这项研究的数据可用于形成一种有科学依据的方法,对磷虾原料进行进一步的技术加工,并有针对性地提取某些脂类物质和成分。

Because insufficient relevant data are available, the component composition of flowers was studied comparatively in six lilac species of the genus Syringa L. (Oleaceae): S. emodi Wall., S. josikaea Jacg., S. komarowii Schneid., S. reticulata (Blume) H. Hara ssp. amurensis (Rupr.) P. S. Green et M. C. Chang, S. sweginzowii Koehne et Lingelsh, and S. vulgaris L. Plants were from the collection of the South Ural Botanical Garden-Institute. Contents were established for major groups of biologically active substances (BASs): flavonoids, hydroxycinnamic acids, tannins, and organic acids. The highest contents of all BAS groups were observed in S. komarowii flowers: flavonoids, 4.25 ± 0.21%; hydroxycinnamic acids, 6.13 ± 0.29%; tannins, 9.3 ± 0.5%; ascorbic acid, 0.468 ± 0.022%; and organic acids, 10.7 ± 0.5%. The contents were somewhat lower in S. emodi and S. sweginzowii and minimum in S. josikaea. Comparisons of the qualitative and quantitative BAS profiles showed that certain Syringa species cultivated in the Republic of Bashkortostan are promising to further study in terms of their possible use in scientific medicine and the development of herbal remedies.

由于相关数据不足,我们对丁香属(油茶科)的六个丁香品种的花朵成分进行了比较研究:S. emodi Wall.、S. josikaea Jacg.、S. komarowii Schneid.、S. reticulata (Blume) H. Hara ssp. amurensis (Rupr.) P. S. Green et M. C. Chang、S. sweginzowii Koehne et Lingelsh 和 S. vulgaris L. 植物来自南乌拉尔植物园研究所的藏品。确定了生物活性物质(BAS)的主要类别:黄酮类、羟基肉桂酸、单宁酸和有机酸。在 S. komarowii 花中观察到所有 BAS 组的含量最高:黄酮类化合物,4.25 ± 0.21%;羟基肉桂酸,6.13 ± 0.29%;单宁酸,9.3 ± 0.5%;抗坏血酸,0.468 ± 0.022%;有机酸,10.7 ± 0.5%。S. emodi 和 S. sweginzowii 的含量略低,而 S. josikaea 的含量最低。对 BAS 的定性和定量分析比较表明,巴什科尔托斯坦共和国栽培的某些丁香树种在科学用药和草药开发方面很有希望得到进一步研究。

New Data on Fungal Species Composition in Spruce Trunk Canker. 云杉树干腐烂病真菌物种组成的新数据。

The composition of canker mycobiota on spruce trunks was studied in the Lisinsky forestry (Leningrad Oblast). Small cankers or canker parts were placed in a humid chamber. Fungi were identified by morphological features. Sorocybe resinae (Fr.) Fr. and Penicillium glaucoalbidum (Desm.) Houbraken & Samson were the most common. The S. resinae occurrence was 75.9 ± 7.9%. The fungus developed in the surface layers of dried resin, but was not detected in the absence of resin production. The fungus S. resinae was therefore assumed to be a nearly ubiquitous component of the mycobiota of resinous cankers on spruce trunks in Leningrad Oblast. The fungus P. glaucoalbidum has only been observed as a saprotroph in Russia earlier. Weak pathogenic properties were detected in the species in experiments; i.e., P. glaucoalbidum grew on live bark tissues in a humid chamber. Based on its high occurrence (41.4 ± 9.1%), P. glaucoalbidum was identified as a regular component of the microbiota in spruce necrotic canker. Pure cultures of P. glaucoalbidum and Oidiodendron sp. were obtained. To test the respective species as possible causative agents of trunk canker, trunks of 20 spruce trees were inoculated with the fungal cultures in a forest stand. The cultures stimulated resin secretion without causing necrosis to spread beyond the inflicted wound. To better understand the phenomenon, a more detailed study of the biota in necrotic cankers is necessary to perform with a special focus on their nonpathogenic part, which has not received proper attention as of yet.

在利辛斯基林场(列宁格勒州)研究了云杉树干上腐烂菌群的组成。将小的腐烂病菌或腐烂病菌部分置于潮湿的室内。根据形态特征对真菌进行鉴定。最常见的真菌是 S. resinae (Fr.) Fr.和 Penicillium glaucoalbidum (Desm.) Houbraken & Samson。S. resinae 的出现率为 75.9 ± 7.9%。这种真菌生长在干燥树脂的表层,但在没有树脂产生的情况下检测不到。因此,在列宁格勒州云杉树干上的树脂蛀孔中,S. resinae 真菌几乎无处不在。早先在俄罗斯只观察到 P. glaucoalbidum 真菌的嗜渍菌。在实验中检测到该菌种的致病性较弱,即 P. glaucoalbidum 在潮湿的室内的活树皮组织上生长。根据其较高的出现率(41.4 ± 9.1%),P. glaucoalbidum 被确定为云杉坏死腐烂病微生物群的常规成分。获得了 P. glaucoalbidum 和 Oidiodendron sp.的纯培养物。为了检验这两种真菌是否可能是树干腐烂病的致病菌,在林地中将真菌培养物接种到 20 棵云杉的树干上。培养物能刺激树脂分泌,但不会导致坏死蔓延到伤口以外。为了更好地理解这一现象,有必要对坏死树干中的生物区系进行更详细的研究,并特别关注它们的非致病性部分,因为这部分至今尚未得到适当的关注。

New remains of a Taymyr mammoth, including bones, bone collagen, hairs, skin, and soft (muscle and fat) tissues were studied comprehensively by mineralogical, spectroscopic, chromatographic, and isotope-geochemical methods. The results were used to infer the mammoth's biological age and diet, paleoclimatic conditions, and the mechanisms and degree of fossilization of the remains.

Myxomycetes are amoeboid fungus-like organisms (Amoebozoa) with a unique life cycle characterized by a great morphological diversity of fruiting bodies. Due to the similarity of these structures to the fruiting bodies of some representatives of Ascomycota and Basidiomycota, myxomycetes have been classified as fungi since the first known scientific description in 1654. Only in the 19th century, when their life cycle was studied, did the difference of this group from fungi become clear. During the same period, microscopic structures of fruiting bodies, as well as ornamentation of the spore surface, began to be considered as diagnostic features. Due to this, in the period from the end of the 19th to the middle of the 20th century, a rather stable system was formed. However, as further studies have shown, both macro- and micromorphological characters are often quite variable, depend on environmental conditions, and often result from convergent evolution, which causes difficulties in defining species and taxonomic units of higher ranks. Since the first decade of the 21st century, due to the development of molecular genetic methods and the accumulation of data on nucleotide sequences of marker genes together with the improvement of microscopic studies, it has been possible to obtain data on the evolutionary relationships of different groups of myxomycetes. A milestone in this process was the publication of the first phylogenetic system of myxomycetes in 2019. This work was the starting point for a number of studies on the relationships between different groups of myxomycetes at a lower taxonomic level. Thus, there has been a surge in the number of studies that bring us closer to constructing a natural system.

摘要--木霉菌属(myxomycetes)是一种具有独特生命周期的类变形真菌生物(变形虫),其特征是子实体形态各异。由于这些结构与子囊菌界(Ascomycota)和担子菌界(Basidiomycota)某些代表菌的子实体相似,因此自 1654 年首次科学描述以来,霉菌就一直被归类为真菌。直到 19 世纪,人们对它们的生命周期进行了研究,才清楚地认识到这一群体与真菌的区别。在同一时期,子实体的显微结构以及孢子表面的装饰开始被视为诊断特征。因此,从 19 世纪末到 20 世纪中叶,形成了一个相当稳定的体系。然而,进一步的研究表明,宏观和微观形态特征往往变化很大,取决于环境条件,而且往往是趋同进化的结果,这给界定物种和更高等级的分类单元造成了困难。自 21 世纪第一个十年以来,由于分子遗传学方法的发展、标记基因核苷酸序列数据的积累以及显微镜研究的改进,人们有可能获得关于不同菌类的进化关系的数据。在这一过程中的一个里程碑是 2019 年发表的第一个霉菌系统发育体系。以这项工作为起点,在较低的分类学水平上对不同菌类之间的关系进行了大量研究。因此,研究数量激增,使我们更接近构建一个自然系统。
