    查看更多>>摘要：Known as the "Queen of Flowers," the rose is one of the most beloved flowers in the world. Although there are more than 37 000 cultivars of roses, novel forms must be created due to environmental and socioeconomic changes or advancements. An extensive knowledge of varietal variability is crucial for rose breeding, but the abundance of rose types and various estimating techniques sometimes hinder objective assessment. Different rose cultivars with varying features and fitness for use were evaluated in the current study, belonging to four groups: shrubs, floribundas, hybrid teas, and climbers. Based on the main traits of plant growth and vigor, flowers, foliage, and reaction to biotic and abiotic stress factors, it was computed the overall value, as a "general value" of tested cultivars and how the component elements (morphological traits or appreciate visually through notation) contribute to the ensemble of the ornamental and landscaping value. Valuable cultivars have been identified that deserve to be used in similar ecological conditions, or that can be recommended as potential parentals in new hybridizations (e.g. 'Monica' for the overall quality of the flowers and ornamental elements, 'Pasiune in Mov' and 'Rosagold' for fragrant flowers, 'Perla Transilvaniei' for intense flowering, and 'Rosarium Utersen' for durability of the flowers). In addition to the phenotypic evaluation, the genetic evaluation revealed information about the potential for hybridization using the cultivars as parents and the possibility of transferring the desired features to their offspring. Hypotheses were also issued regarding the use of appropriate statistics and multivariate analysis for the evaluation of quantitative or qualitative characteristics in roses and their relationships.

    查看更多>>摘要：Microtus elbeyli was first identified based on the morphological and karyological differences from Elbeyli district of Kilis province (southeastern Anatolia). In the first molecular systematics study of M. elbeyli; mitochondrial Cytochrome-b (CYTB) and Cytochrome oxidase-I (COI) gene analyses were performed in order to clarify the taxonomy of M. elbeyli comparing to other vole species (M. dogramacii, M. hartingi, M. guentheri, M. schidlovskii). Evidences from Bayesian MCMC trees and Median-joining networks pointed that M. elbeyli did not split from M. dogramacii and the mean genetic distance values between M. elbeyli and M. dogramacii were notably low. Although M. elbeyli and M. dogramacii differ regarding karyological features, external morphology, and some skull characteristics, in the light of mitochondrial gene analyses, it was suggested that M. elbeyli (2n = 46) and M. dogramacii (2n = 48) are the same species and the taxonomic status of southeastern Anatolian population was assigned to subspecies as Microtus dogramacii elbeyli.

    1.1-1.12页
    查看更多>>摘要：Background: The dysregulation of fatty acid metabolism (FAM) is pivotal for the occurrence and development of cancer. However, the prognostic value of genes associated with FAM in clear cell renal cell carcinoma (ccRCC) characterized by the presence of numerous lipid droplets remains elusive. To construct a multiple FAM gene prognosis model of ccRCC using the TCGA database. The model was combined with clinical features, and a nomograph was established and weighted. In addition, the infiltration of immune cells in tumor microenvironment (TME) was also studied. Seven genes associated with FAM (HACD1, HPGD, CPT1B, SCD5, GAD2, IL4I1, CPT2) were chosen to establish a prognosis model, and ccRCC patients were separated into high and low risk groups. ROC analysis and principal component analysis (PCA) showed that the model exhibited the best performance. The prediction capability of the nomogram was verified by the ROC curve, calibration diagram and decision curve analysis (DCA). Tumor microenvironment and immune cell infiltration analysis were associated with risk scores in ccRCC patients. There were remarkable diversities in the expression of immuno-checkpoints and RNA methylation regulatory genes in both groups. The prognosis model using genes related to FAM exhibits a satisfactory prediction power, which can ameliorate personalized therapies for ccRCC patients.

    Prevention of Carbohydrate Metabolism Disorders in Rats by the Phlorotannins Complex of the Marine Brown Alga Sargassum pallidum under an Acute Alcohol Impact

    Sprygin, V. G.Fomenko, S. E.Kushnerova, N. F.
    1.1-1.10页
    查看更多>>摘要：It is shown that the complex of phlorotannins isolated from the marine brown alga Sargassum pallidum protects the pool of the oxidized form of NAD+-NADP+ from depletion during an acute alcohol impact. Restoration of the NAD+/NADH ratio provided preservation of the redox potential in liver, necessary level of oxidized forms of metabolites of lactate dehydrogenase and glycerol-3-phosphate dehydrogenase shuttle cycles for maintenance of reactions of aerobic glycolysis and gluconeogenesis, regulation of the pentose phosphate cycle, promoted prevention of tissue hypoxia and normalization of the blood glucose level. This provides a basis for recommending the use of phlorotannin complexes as a prophylactic agent to attenuate the toxic effects of ethanol.

    查看更多>>摘要：Nanotechnology is one of the most popular sciences in recent years due to its usage in many fields. Herein, synthesis of silver nanoparticles (AgNPs) was accomplished using alfalfa (Medicago sativa L.) and their structures were established by spectroscopy. The surface plasmon resonance appeared at 449 nm in UV-Vis spectroscopy. The compound moieties acting as reducing agent was determined by FTIR. The XRD analysis showed the signals (2 theta) at 38.1 degrees, 46.3 degrees, 65.0 degrees, 77.4 degrees and indexed to [111, 020, 202, 131] facets respectively indicating the structure as face-centered cubic. Scherrer equation with PANanalytical X'Pert-High Score software revealed the particle size to be 18 nm. The morphology of AgNPs was established by TEM and particle dimension was determined as 16 nm. The cytotoxicity of extract and AgNPs were performed using the Capan-1, MCF-7, DLD-1, H1299, and L929. Treatment of the extract and AgNPs with Capan-1 cell lines at 0.125 mu g/mL resulted in cell viability of 11.5 and 10.6%. In addition, the viability of MCF-7 cells was observed as 63.2 and 58.5% at 1.0 mu g/mL respectively after the treatment of extract and AgNPs. The best activity of extract and AgNPs was observed at 1.0 mu g/mL on DLD-1 cell lines with percent viability of 24.4 and 31.6. The moderate activity of extract and AgNPs was observed on H-1299 cells. The high cytotoxicity was not detected by AgNPs on normal L929 cell lines which is a desirable situation.

    查看更多>>摘要：In this study, to explore the effects of plant growth regulators 6-benzylaminopurine (BAP), Paclobutrazol (PBZ) and thidiazuron (TDZ) on the ornamental traits and physiology of Dendrobium denneanum Kerr. Different concentrations of BAP (200, 400, 600 mg/L), PBZ (1000, 1500, 2000 mg/L) and TDZ (10, 20, 40 mg/L) were set up to treat D. denneanum, and spraying water served as control (CK). The changes in flowering traits and physiological indexes of D. denneanum were observed and analyzed, while the content of endogenous hormones in its flowering process was determined by liquid chromatography. The results showed that 400 mg/L BAP, 2000 mg/L PBZ and 40 mg/L TDZ are beneficial for the formation of flowering quality in D. denneanum. Their ability to increase the content of photosynthetic pigments in D. denneanum leaves and slow down the loss of soluble sugars and soluble proteins during flowering, as well as increase the activities of superoxide dismutase (SOD) and peroxidase (POD) and reduce the content of malondialdehyde (MDA). Through the analysis of endogenous hormones, it was found that high levels of gibberellin (GA) favored flower bud differentiation and promoted flowering, while low levels of indole acetic acid (IAA) in the early stage favored the induction of flowering, and high levels of IAA in the later stage favored the establishment of flower morphology, compared with high levels of Zeatin (ZT) in the early stage, which induced flowering, and low levels of ZT in the later stage favored the morphology of flower differentiation.

    查看更多>>摘要：Metal pollution is increasing in Turkiye and coastal environments due to factors such as urbanization, industrialization, agricultural activities, sea transportation, domestic waste and emissions from various industrial facilities in the eastern Mediterranean, Aegean and Marmara Seas. This pollution has resulted in the contamination of marine ecosystems, affecting algae, fish and marine invertebrates with a variety of metals. The aim of this study was to define the accumulation of Aluminum (Al), Chromium (Cr), Cobalt (Co), Nickel (Ni), Cadmium (Cd), Lead (Pb), Manganese (Mn), Iron (Fe), Copper (Cu) and Zinc (Zn) elements in different tissues of the European squid, Loligo vulgaris, including the mantle (muscle), gills, hepatopancreas (liver) and gonads. Metal distribution in the mantle tissue of the L. vulgaris was observed to be Zn > Fe > Cu > Al > Pb > Mn > Cr > Ni > Cd > Co, in the gill tissue it was Fe > Al > Cu > Mn > Pb > Cr > Ni > Cd > Co and in the hepatopancreas tissue it was Cu > Fe > Zn > Al > Mn > Pb > Cd > Cr > Co > Ni, based on average values. To assess potential hazards to human health related with the consumption of L. vulgaris, the research computed Target Hazard Coefficient (THQ), Hazard Index (HI), and Cancer Risk (CR) metrics for elements, both carcinogenic and non-carcinogenic, accumulated in the mantle tissue. The results suggested that the consumption of L. vulgaris, harvested from the coasts of Turkiye, does not present significant health risks to humans.

    查看更多>>摘要：Petroleum, or crude oil, is a vital natural resource that plays a significant role in modern society. However, improper petroleum utilization can cause environmental harm, particularly in aquatic ecosystems. Currently, the use of microorganisms for the elimination of toxic and harmful compounds is very promising. Therefore, this study aimed to isolate potential hydrocarbon-degrading bacteria from different contamination sites, including Paotere Port, Kayu Bangkoa Pier, and Popsa Pier South Celebes, Indonesia. The bacterial samples obtained were screened for their ability to reduce surface tension using a Du Novy tensiometer. The percentage of biodegradation was calculated based on the gravimetric test. The results showed that the maximum reduction in surface tension occurred at the end of the exponential growth phase. Furthermore, a high biodegradation rate was found; PT isolates could degrade petroleum hydrocarbons by 52.03%, KB isolates by 52.97%, and PS isolates by 39.90%.

    1.1-1.11页
    查看更多>>摘要：Endemic to China, the endangered tree species Malania oleifera possesses significant medicinal, ecological, and economic importance. However, there is a paucity of research on the physiological responses of M. oleifera seedlings to drought stress. We utilized one-year-old seedlings to investigate the morphological alterations and physiological reactions under simulated natural drought conditions in this study. The findings revealed significant variations in root length, plant height, stem diameter, and root count between drought-stressed and control groups. As the severity of drought increased, M. oleifera exhibited an initial increase followed by a decrease in root length, while plant height and fresh weight showed a notable decline. Chlorophyll content (a + b, a, b) was found to be reduced under drought conditions compared to the control, with further reduction as the duration of stress extended. The levels of malondialdehyde (MDA) and soluble sugars progressively increased with prolonged stress exposure. Similarly, the concentrations of soluble proteins, proline, and the activities of protective enzymes such as superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) initially rose but then declined as drought stress intensified. In summary, the morphology, physiology and biochemistry of M. oleifera seedlings under drought stress have undergone significant changes, such as significant inhibition of seedling growth, root development, reduction of chlorophyll content, and significant increase in malondialdehyde content. In particular, the accumulation of osmotic regulators such as proline and the enhancement of enzyme defense systems to varying degrees alleviate the adverse effects of drought.
