raventricular neuroendoscopic procedures.In the present investigation, the feasibility of detecting the chlorofluoromethane (CFM) gas molecule onto the outer surface of pristine single layer boron nitride nanosheet (BNNS), as well as its aluminum (Al)- and gallium (Ga)-doped structures, was carefully evaluated. For achieving this goal, a density functional theory level of study using the Perdew, Burke, and Ernzerhof exchange-correlation (PBEPBE) functional together with a 6-311G(d) basis set has been used. Subsequently, the B3LYP, CAM-B3LYP, wB97XD, and M062X functionals with a 6-311G(d) basis set were also employed to consider the single-point energies. Natural bond orbital (NBO) and quantum theory of atoms in molecules (QTAIM) were implemented by using the B3LYP-D3/6-311G(d) method, and the results were compatible with the electronic properties. In this regard, the total density of states (TDOSs), the Wiberg bond index (WBI), natural charge, natural electron configuration, donor-acceptor natural bond orbital interactions, and the second-order perturbation energies are performed to explore the nature of the intermolecular interactions. All of the energy calculations and population analyses denote that by adsorbing of the gas molecule onto the surface of the considered nanostructures, the intermolecular interactions are of the type of strong chemical adsorption. Among the doped nanosheets, Ga-doped nanosheet has very high adsorption energy compared with other elements (i.e., Ga-doped > Al-doped > pristine). Generally, it was revealed that the sensitivity of the adsorption will be increased when the gas molecule interacts with decorated nanosheets and decrease the HOMO-LUMO band gap; therefore, the change of electronic properties can be used to design suitable nanosensors to detect CFM gas. Graphical abstract.At high temperatures, ventricular beating rate collapses and depresses cardiac output in fish. The role of sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA) in thermal tolerance of ventricular function was examined in brown trout (Salmo trutta) by measuring heart SERCA and comparing it to that of the dorsolateral myotomal muscle. Activity of SERCA was measured from crude homogenates of cold-acclimated (+ 3 °C, c.a.) and warm-acclimated (+ 13 °C, w.a.) brown trout as cyclopiazonic acid (20 µM) sensitive Ca2+-ATPase between + 3 and + 33 °C. Activity of the heart SERCA was significantly higher in c.a. than w.a. trout and increased strongly between + 3 and + 23 °C with linear Arrhenius plots but started to plateau between + 23 and + 33 °C in both acclimation groups. The rate of thermal inactivation of the heart SERCA at + 35 °C was similar in c.a. and w.a. fish. Activity of the muscle SERCA was less temperature dependent and more heat resistant than that of the heart SERCA and showed linear Arrhenius plots between + 3 and + 33 °C in both c.a. and w.a. fish. SERCA activity of the c.a. muscle was slightly higher than that of w.a. muscle. The rate of thermal inactivation at + 40 °C was similar for both c.a. and w.a. muscle SERCA at + 40 °C. Although the heart SERCA is more sensitive to high temperatures than the muscle SERCA, it is unlikely to be a limiting factor for heart rate, because its heat tolerance, unlike that of the ventricular beating rate, was not changed by temperature acclimation.In the present study, the nematicidal activity of an isolated strain of Mimosa pudica nodules was evaluated against the Nacobbus aberrans (J2) phytonymatodes with a mortality of 88.8%, while against the gastrointestinal nematode Haemonchus contortus (L3) and free-living Panagrellus redivivus was 100%. The ability to inhibit the growth of phytopathogenic fungi Fusarium sp., and Alternaria solani, as well as the oomycete Phytophthora capsici, this antifungal activity may be related to the ability to produce cellulases, siderophores and chitinases by this bacterial strain. Another important finding was the detection of plant growth promoter characteristics, such as auxin production and phosphate solubilization. The strain identified by sequences of the 16S and rpoB genes as Serratia sp. is genetically related to Serratia marcescens and Serratia nematodiphila. The promoter activity of plant growth, antifungal and nematicide of the Serratia sp. strain makes it an alternative for the biocontrol of fungi and nematodes that affect both the livestock and agricultural sectors, likewise, candidate as a growth-promoting bacterium.Mapping of effective protein domains is a demanding stride to disclose the functional relationship between regulatory complexes. Domain analysis of protein interactions is requisite for understanding the pleiotropic responses of the respective partners. Cti6 is a multifunctional regulator for which we could show recruitment of co-repressors Sin3, Cyc8 and Tup1. However, the responsible core domain tethering Cti6 to these co-repressors is poorly understood. Here, we report the pivotal domain of Cti6 that is indispensable for co-repressor recruitment. We substantiated that amino acids 450-506 of Cti6 bind PAH2 of Sin3. Ridaforolimus mTOR inhibitor To analyse this Cti6-Sin3 Interaction Domain (CSID) in more detail, selected amino acids within CSID were replaced by alanine. It is revealed that hydrophobic amino acids V467, L481 and L491 L492 L493 are important for Cti6-Sin3 binding. In addition to PAH2 of Sin3, CSID also binds to tetratricopeptide repeats (TPR) of Cyc8. Indeed, we could demonstrate Cti6 recruitment to promoters of genes, such as RNR3 and SMF3, containing iron-responsive elements (IRE). Importantly, Sin3 is also recruited to these promoters but only in the presence of functional Cti6. Our findings provide novel insights toward the critical interaction domain in the co-regulator Cti6, which is a component of regulatory complexes that are closely related to chromatin architecture and the epigenetic status of genes that are regulated by pleiotropic co-repressors.A novel chitinolytic bacterium Chitinibacter sp. GC72, which produces an enzyme capable of efficiently converting chitin only into N-acetyl-D-glucosamine (GlcNAc), was successfully sequenced and analyzed. The assembled draft genome of strain GC72 is 3,455,373 bp, containing 3346 encoded protein sequences with G + C content of 53.90%. Among these annotated genes, 17 chitinolytic enzymes including 12 glycoside hydrolase family 18 chitinases, three family 19 chitinases, one family 20 β-hexosaminidase, and one auxiliary activity family 10 lytic polysaccharide monooxygenase, were found to be essential in the production of GlcNAc from chitin. The genomic information of strain GC72 provides a reference genome for Chitinibacter bacteria and abundant novel chitinolytic enzyme resources, and allows researchers to explore potential applications in GlcNAc enzymatic production.
