infestans towards various potato cultivars. Taken together, Cd not only affected hyphal growth rate and caused biochemical changes in P. infestans structures, but accelerated the pathogenicity as well. The nitro-oxidative homeostasis imbalance underlies the phytopathogen adaptive strategy and survival in the heavy metal contaminated environment.Cultivated cardoon (Cynara cardunculus var. altilis) has long been used as a food and medicine remedy and nowadays is considered a functional food. Its leaf bioactive compounds are mostly represented by chlorogenic acids and coumaroyl derivatives, known for their nutritional value and bioactivity. selleck chemicals Having antioxidant and hepatoprotective properties, these molecules are used for medicinal purposes. Apart from the phenolic compounds in green tissues, cultivated cardoon is also used for the seed oil, having a composition suitable for the human diet, but also valuable as feedstock for the production of biofuel and biodegradable bioplastics. Given the wide spectrum of valuable cardoon molecules and their numerous industrial applications, a detailed characterization of different organs and tissues for their metabolic profiles as well as an extensive transcriptional analysis of associated key biosynthetic genes were performed to provide a deeper insight into metabolites biosynthesis and accumulation sites. This studyl screening could be useful to guide the selection of superior genotypes.Endoscopic ultrasound (EUS)-guided interventions provide easy access to structures adjacent to the gastrointestinal tract, effectively targeting them for therapeutic purposes. They play an important role in the management of pancreatic fluid collections (PFC) and bile duct (BD) and pancreatic duct (PD) drainage in cases of failed endoscopic retrograde cholangiopancreatography (ERCP) or gallbladder (GB) drainage. Specially designed stents and delivery systems for EUS-guided transluminal interventions allow various new applications and improve the efficacy and safety of these procedures. In fact, EUS-guided drainage has emerged as the treatment of choice for the management of PFC, and recent innovations such as fully covered metal stents (including lumen-apposing metal stents) have improved outcomes in patients with walled-off necrosis. Similarly, EUS-guided BD and PD drainage with specially designed stents can be beneficial for patients with failed ERCP due to an inaccessible papilla, gastric outlet obstruction, or surgically altered anatomy. EUS-guided GB drainage is also performed using dedicated stents in patients with acute cholecystitis who are not fit for surgery. Although the field of dedicated stents for interventional EUS is rapidly advancing with increasing innovations, the debate on the most appropriate stent for EUS-guided drainage has resurfaced. Furthermore, some important questions remain unaddressed, such as which stent improves clinical outcomes and safety in EUS-guided drainage. Herein, the current status and problems of the available stents are reviewed, including the applicable indications, long-term clinical outcomes, comparison between each stent, and their future prospects.Heat shock transcription factor (Hsf) plays an important role in regulating plant thermotolerance. The function and regulatory mechanism of CaHsfA1d in heat stress tolerance of pepper have not been reported yet. In this study, phylogenetic tree and sequence analyses confirmed that CaHsfA1d is a class A Hsf. CaHsfA1d harbored transcriptional function and predicted the aromatic, hydrophobic, and acidic (AHA) motif mediated function of CaHsfA1d as a transcription activator. Subcellular localization assay showed that CaHsfA1d protein is localized in the nucleus. The CaHsfA1d was transcriptionally up-regulated at high temperatures and its expression in the thermotolerant pepper line R9 was more sensitive than that in thermosensitive pepper line B6. The function of CaHsfA1d under heat stress was characterized in CaHsfA1d-silenced pepper plants and CaHsfA1d-overexpression Arabidopsis plants. Silencing of the CaHsfA1d reduced the thermotolerance of the pepper, while CaHsfA1d-overexpression Arabidopsis plants exhibited an increased insensitivity to high temperatures. Moreover, the CaHsfA1d maintained the H2O2 dynamic balance under heat stress and increased the expression of Hsfs, Hsps (heat shock protein), and antioxidant gene AtGSTU5 (glutathione S-transferase class tau 5) in transgenic lines. Our findings clearly indicate that CaHsfA1d improved the plant thermotolerance via regulating the expression of stress- and antioxidant-related genes.Campylobacter species are common commensals in the gastrointestinal tract of livestock animals; thus, animal-to-human transmission occurs frequently. We investigated for the first time, class 1 integrons and associated gene cassettes among pan drug-resistant (PDR), extensively drug-resistant (XDR), and multidrug-resistant (MDR) Campylobacter species isolated from livestock animals and humans in Egypt. Campylobacter species were detected in 58.11% of the analyzed chicken samples represented as 67.53% Campylobacter jejuni(C. jejuni) and 32.47% Campylobacter coli (C. coli). C. jejuni isolates were reported in 51.42%, 74.28%, and 66.67% of examined minced meat, raw milk, and human stool samples, respectively. Variable antimicrobial resistance phenotypes; PDR (2.55%), XDR (68.94%), and MDR (28.5%) campylobacters were reported. Molecular analysis revealed that 97.36% of examined campylobacters were integrase gene-positive; all harbored the class 1 integrons, except one possessed an empty integron structure. DNA sequence analysis revealed the predominance of aadA (81.08%) and dfrA (67.56%) alleles accounting for resistance to aminoglycosides and trimethoprim, respectively. This is the first report of aacC5-aadA7Δ4 gene cassette array and a putative phage tail tape measure protein on class 1 integrons of Campylobacter isolates. Evidence from this study showed the possibility of Campylobacter-bacteriophage interactions and treatment failure in animals and humans due to horizontal gene transfer mediated by class 1 integrons.
