An anatomical study of adventitious roots of three Salix clones, B-44, SV068 and SM4041, treated with 3 and 6 mg Cd kg-1 dry weight in soil in a greenhouse experiment. The aim was to analyze the anatomical characteristics of roots in response to pollution by cadmium and to assess the potential application of anatomical and hydraulic characteristics in the selection of the most suitable Salix clones for phytostabilization of pollutants in soils. Anatomical parameters measured in this study included root crosssectional area, root diameter, the proportion of periderm, secondary phloem (cortex) and wood (secondary and primary xylem), and parameters of the vessels (lumen area, diameter and frequency). Based on the measurements of individual vessel lumens and the number of vessels, the theoretical hydraulic conductivity (kh) of roots was calculated. The effects of applied Cd concentrations on root traits were studied in clones and control plants. Following treatments with both Cd concentrations, plants of clone B-44 had the highest values of most parameters and significantly higher kh in comparison with control samples due to the significantly larger root cross-sectional area and lumen of vessels. It was concluded that these characteristics can serve for effective evaluation and selection of clones for remediation of sites contaminated with cadmium.
3和6 mg Cd kg-1干重处理下柳B-44、SV068和SM4041三个无性系不定根的解剖研究。目的是分析柳树根系对镉污染响应的解剖特征，并评估解剖和水力特征在选择最适合土壤中污染物植物稳定的柳树无性系中的潜在应用。本研究测量的解剖学参数包括根横截面积、根直径、周皮、次生韧皮部(皮层)和木材(次生和初生木质部)的比例以及血管参数(管腔面积、直径和频率)。通过对单个管腔和管数的测量，计算了根的理论导水系数kh。研究了施用镉浓度对无性系和对照植株根系性状的影响。在两种Cd浓度处理下，无性系B-44植株的根横截面积和管腔均显著增大，大部分参数值最高，kh值显著高于对照。这些特征可为镉污染场地修复无性系的评价和选择提供有效依据。

The distribution and spread of a new alien gastropod species, Clathrocaspia knipowitschii (Makarov, 1938) (Gastropoda: Hydrobiidae: Caspiinae) in the Danube River was examined. First findings of this species for Hungary, Slovakia, Romania, Bulgaria and Serbia are presented. Clathrocaspia knipowitschii was initially found in 2013 in the Iron Gate stretch of the Danube River at the border between Romania and Serbia. In 2019 and 2020, the species was found at several sites in the lower Danube in Romania, Serbia and Bulgaria, and also upstream in the middle Hungarian Danube in high population densities. The species appears to have spread along more than 800 km in six years. This finding together with the available abundance data indicates that C. knipowitschii is potentially an invasive species, but further observations are needed.

Retinoic acid receptor ? (RAR?) is a transcription factor that plays an essential role in tumor progression. Triple-negative breast cancer (TNBC) is a subtype of breast carcinoma with a poor prognosis due to early therapeutic escape from conventional treatments and aggressive metastatic relapse by the occurrence of an epithelial-mesenchymal transition (EMT). However, as the expression level of RAR? does not correlate with the overall survival of TNBC patients, we speculate that post-translational modification such as phosphorylation of RAR? may be involved in EMT and TNBC metastasis. After overexpressing a phosphorylation-defective mutant of RAR? at serine 77 residue (RAR?S77A), we found that RAR? hypophosphorylation inhibited MDA-MB-231 cell motility and migration in vitro while reducing the lung metastatic potential in vivo. This was accompanied by increased expression of the epithelial marker E-cadherin and decreased expression of the mesenchymal markers ?-catenin and zinc finger E-box-binding homeobox 1 (ZEB1) in agreement with the suppression of EMT. Interestingly, the overexpression of wild-type RAR? in the presence of the RAR? agonist AM580 failed to suppress EMT and cell migration. These results indicate that hypophosphorylated RAR?S77 can directly mimic activated RAR? to inhibit EMT and migration/invasion of cells, thus providing a novel target in the therapeutic intervention of TNBC.

F1012-2, a novel sesquiterpene lactone isolated from the Chinese herbal medicine Eupatorium lindleyanum DC, exhibits an antitumor effect. In this study, we investigated the anticancer activities of F1012-2 on ten human breast cancer lines and demonstrated significantly lower IC50 values for triple-negative breast cancer (TNBC) than for non-TNBC cell lines. The transcription factors p53 and nuclear factor-?B (NF-?B) are important regulators of tumorigenesis. F1012-2 not only depleted mutant p53, but also activated wild-type p53. F1012-2 reduced the expression of phosphorylated p65 and p105 F-?B family members and coregulated p53, NF-?B members and their dependent targets. To further clarify the key role of p53, lentivirus small hairpin RNA (shRNA) infection was used to knockdown p53 in MDAMB- 231 cells. F1012-2 significantly reduced the inhibitory effect on cell proliferation and apoptosis, while the levels of p53, NF-?B family members and their dependent genes were not significantly different. F1012-2 exhibited a significant antitumor effect and reduced the expression of p53 in MDA-MB-231 xenografts. Taken together, our results show that F1012-2 exhibited an inhibitory effect on TNBC and affected the regulation of p53/NF-?B signaling pathways.

The study aimed to assess the oncologic and reproductive outcome of fertility-sparing treatment of stage I borderline ovarian tumors (BOTs). A retrospective study of patients aged 18-40 years with stage I BOTs surgically treated during a 10-year period was conducted. In total, 52 patients (average age 32.7+/-5.9) were followed for 16 to 137 months after BOT diagnosis (mean 73.4 months). The overall survival rate was 100%. Recurrence was registered in 4 patients (7.7%). All patients underwent a unilateral salpingo-oophorectomy and all histologic findings corresponded with primary BOTs (3 serous; 1 endometrioid). Higher parity increased while the histological type and stage did not impact recurrence. Average recurrence-free survival was 36.2+/-23.6 months regardless of histological type and stage. Recurrence occurred during the first 3 postoperative years in 75% of cases. Out of 45 women treated with fertility-sparing surgery, 64.4% attempted pregnancy and the pregnancy success rate was 44.8%. Only one pregnancy was conceived by assisted reproduction, while all others were spontaneous. The fertilitysparing treatment in stage I borderline ovarian tumors can be a safe and successful option both in terms of oncologic and reproductive outcomes, regardless of patient and treatment characteristics. Pregnancies after BOT surgery can be achieved with satisfactory rates and adequate outcomes.

Aquatic ecosystems are recipients of various contaminants including pesticides. For many years, pyrethroid insecticides (e.g., tau-fluvalinate) have been used extensively in agricultural activities to control pests. However, they can affect not only target organisms but also non-target organisms. This study was conducted to investigate the lethal and sublethal effects of tau-fluvalinate on the non-target organism Gammarus roeseli. To this end, acute toxicity of tau-fluvalinate was determined using a toxicity test with a 96-h exposure period, and the genotoxic effects of different sublethal concentrations on hemocytes of the test organism were assessed at 24-, 96-, and 240-h exposure periods using the comet assay. Alterations in locomotor activity of the test organism in response to exposure to sublethal concentrations were evaluated at 120- and 240-h periods. The 96-h median lethal concentration (LC50) was found to be 17.29 ?g/L, and tau-fluvalinate was observed to cause a significant increase in DNA damage and a significant reduction in locomotor activity at the tested sublethal concentrations (2.15, 4.30 and 8.60 ?g/L). The results of this study suggest that the long-term existence of tau-fluvalinate in aquatic environments at high concentrations is a noteworthy threat to non-target organisms and that its use in agricultural activities should be reconsidered.

As oxidative stress is implicated in the pathogenesis of head and neck squamous cell cancer (HNSCC), the functions of antioxidant enzyme systems and DNA repair proteins are critical in the development of cancer. To investigate the role of genetic polymorphisms of the antioxidant superoxide dismutase 2 (SOD2) Val16Ala, glutathione peroxidase 1 (GPX1) Pro198Leu, and the DNA repair Xeroderma Pigmentosum Group D (XPD) Lys751Gln genes under exogenous risk factors, including smoking and alcohol consumption, in HNSCC carcinogenesis, we conducted a case-control study on 139 unrelated cases and 265 non-cancer controls. Polymorphisms were analyzed in additive, dominant and recessive genetic models, individually and in an interaction model. Carriers of the T allele of SOD2 were associated with an increased risk for HNSCC in the overall subgroups of males and smokers; similarly, the T allele of GPX1 was associated with elevated risk in the overall and smoker subgroup. A 12.47-fold increased risk was observed for the carriers of GPX1 TT, SOD2 CT and XPD CC genotypes for HNSCC. This is the first study presenting the potential roles of SOD2, GPX1 and XPD polymorphisms in interaction and under three genetic models in the development of HNSCC. The results suggest that these polymorphisms slightly modify the risk in HNSCC development individually but are significantly higher when they functioned and were evaluated together.

Klebsiella pneumoniae is an opportunistic pathogen that causes a wide range of infections. The emergence and spread of hypervirulent K. pneumoniae (hvKp), which appears to be different from the classical K. pneumoniae (cKp) in several microbiological aspects, is an urgent global threat. However, the virulence characteristics of hvKp and its differences from cKp are poorly understood. This work aimed to investigate the correlation between the expression characteristics of proteins and hypervirulence, using proteomics. Our results revealed that 185 proteins were upregulated while 266 proteins were downregulated in hvKp isolates when compared with cKp isolates. The differentially expressed proteins were functionally categorized according to the Gene Ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway. These proteins were predominantly metabolism associated, which indicates that changes in the metabolic pathways in hvKp isolates might in part contribute to hypervirulence.

The emergence and spread of hypervirulent K. pneumoniae (hvKp), which appears to be different from the classical K. pneumoniae (cKp) in several microbiological aspects, is an urgent global threat. However, the virulence characteristics of hvKp and its differences from cKp are poorly understood. This work aimed to investigate the correlation between the expression characteristics of proteins and hypervirulence, using proteomics. Our results revealed that 185 proteins were upregulated while 266 proteins were downregulated in hvKp isolates when compared with cKp isolates.

Excessive apoptosis of intervertebral disk cells and intervertebral disk degeneration (IDD) is the prime cause of low back pain. B-cell lymphoma 2 (Bcl-2) and adenovirus E1B 19 kDa interacting protein 3 (BNIP3), a member of the Bcl-2 family, are involved in cell autophagy and apoptosis. The roles and mechanisms of BNIP3 in intervertebral disk cell autophagy and apoptosis are unclear. In this study, primary rat intervertebral disk cells were prepared to study the effect of BNIP3 overexpression on their autophagy and apoptosis. The cell counting kit (CCK)-8 assay showed that BNIP3 overexpression decreased cell viability. Real-time PCR and Western blotting showed that BNIP3 overexpression significantly upregulated the expression of autophagy-related proteins and pro-apoptotic proteins, including hypoxia-inducible factor-1?, apoptotic protease activating factor 1, caspase 3 and cleaved caspase 3, microtubule-associated proteins 1A/1B light chain 3 (LC3) and Beclin-1 while downregulating the expression of anti-apoptotic protein Bcl-2. Cell staining detection of autophagy and apoptosis showed that BNIP3 overexpression significantly increased the autophagy and apoptosis of rat intervertebral disk cells. BNIP3 RNA interference revealed that the effects of BNIP3 overexpression can be reversed. These findings suggested that BNIP3 enhanced the autophagy and apoptosis in the rat intervertebral disk cells in vitro, which might promote IDD development.
