The pine wood nematode Bursaphelenchus xylophilus is a destructive pest on Pinus trees and lacks effective control measures. The present study identified a novel nematotoxic cytolytic (Cyt)-like protein originating from the entomopathogenic fungus Conidiobolus obscurus.

The protein was successfully purified using heterologous expression in Escherichia coli and affinity chromatography. N-hydroxysuccinimide-rhodamine-labeled Cyt-like protein was used to establish the route of toxin uptake, and revealed that the toxin can enter the nematode via the stylet. In bioassays, the purified protein had high nematicide activity against B. xylophilus, with a median lethal concentration at 24 h of 15.8 and 29.4 μg mL
for juveniles and adults, respectively. Compared with the deionized water control, fecundity, thrashing, and egg hatching were significantly reduced by 97%, 98%, and 83%, respectively, with 40 μg mL
Cyt-like protein at 24-36 h. Staining with Oil-Red-O showed a decrease in large lipid droplet formation in the protein-treated adult nematodes.

The Cyt-like protein toxin possesses high nematicide activity against B. xylophilus with effects on nematode vitality and fecundity. The potential exists to use the Cyt-like protein for the control of B. xylophilus.

However, salinity affects more than 800 million hectares worldwide, limiting global agricultural production. The aim of this research was to evaluate the structural behaviour of the roots and stems under progressive salt stress, detailing the possible anatomical modifications to these organs in soybean plants during this stress. The plants were randomized into five treatments (0, 50, 100, 150 and 200 mm NaCl). All the root regions studied and exposed to 100 mm Na+ exhibited increases in the epidermis and endodermis and formation of lysogenic aerenchyma with increasing salinity, revealing the protective roles of these structures in reducing Na+ influx. In the stem, increases in the cortex and pith in the first internode subject to 100 mm Na+ suggest anatomical responses that aim to minimize oxidative stress. Soybean plants subjected to progressive salt stress (>50 mm Na+ ) avoided cavitation and loss of function linked to vessel elements, reducing the metaxylem in all the root and stem regions analysed. Finally, our results confirm anatomical changes to the roots and stems.The electrolytes in lithium metal batteries have to be compatible with both lithium metal anodes and high voltage cathodes, and can be regulated by manipulating the solvation structure. Herein, to enhance the electrolyte stability, lithium nitrate (LiNO3 ) and 1,1,2,2-tetrafuoroethyl-2',2',2'-trifuoroethyl(HFE) are introduced into the high-concentration sulfolane electrolyte to suppress Li dendrite growth and achieve a high Coulombic efficiency of >99 % for both the Li anode and LiNi0.8 Mn0.1 Co0.1 O2 (NMC811) cathodes. Molecular dynamics simulations show that NO3- participates in the solvation sheath of lithium ions enabling more bis(trifluoromethanesulfonyl)imide anion (TFSI- ) to coordinate with Li+ ions. Therefore, a robust LiNx Oy -LiF-rich solid electrolyte interface (SEI) is formed on the Li surface, suppressing Li dendrite growth. The LiNO3 -containing sulfolane electrolyte can also support the highly aggressive LiNi0.8 Mn0.1 Co0.1 O2 (NMC811) cathode, delivering a discharge capacity of 190.4 mAh g-1 at 0.5 C for 200 cycles with a capacity retention rate of 99.5 %.(Ca1-x Eux )WO4 (x = 0-21 mol%) phosphors were prepared using the classical solid-state reaction method. The influence of Eu3+ ion doping on lattice structure was observed using powder X-ray diffraction and Fourier transform infrared spectroscopy. Furthermore, under this influence, the luminescence properties of all samples were analyzed. The results clearly illustrated that the element europium was successfully incorporated into the CaWO4 lattice with a scheelite structure in the form of a Eu3+ ion, which introduced a slight lattice distortion into the CaWO4 matrix. These lattice distortions had no effect on phase purity, but had regular effects on the intrinsic luminescence of the matrix and the f-f excitation transitions of Eu3+ activators. When the Eu3+ concentration was increased to 21 mol%, a local luminescence centre of [WO4 ]2- groups was detected in the matrix and manifested as the decay curves of [WO4 ]2- groups and luminescence changed from single exponential to double exponential fitting. Furthermore, the excitation transitions of Eu3+ between different energy levels (such as 7 F0 →5 L6 , 7 F0 →5 D2 ) also produced interesting changes. Based on analysis of photoluminescence spectra and the chromaticity coordinates in this study, it could be verified that the nonreversing energy transfer of [WO4 ]2- →Eu3+ was efficient and incomplete.A growing challenge for risk, vulnerability, and resilience assessment is the ability to understand, characterize, and model the complexities of our joint socioecological systems, often delineated with differing natural (e.g., watershed) and imposed (e.g., political) boundaries at the landscape scale. To effectively manage such systems in the increasingly dynamic, adaptive context of environmental change, we need to understand not just food web interactions of contaminants or the flooding impacts of sea level rise and storm surges, but rather the interplay between social and ecological components within the inherent and induced feedforward and feedback system mechanisms. Risk assessment, in its traditional implementation, is a simplification of a complex problem to understand the basic cause-and-effect relationships within a system. This approach allows risk assessors to distill a complex issue into a manageable model that quantifies, or semiquantifies, the effects of an adverse stressor.

Herein, we investigate the NIR-to-UV/visible emission of sub-15 nm alkaline-earth rare-earth fluoride UCNPs (M1-x Lnx F2+x, MLnF) with a CaF2 shell. We synthesize 8 alkaline-earth host materials doped with Yb3+ and Tm3+ , with alkaline-earth (M) spanning Ca, Sr, and Ba, MgSr, CaSr, CaBa, SrBa, and CaSrBa. We explore UCNP composition, size, and lanthanide doping-dependent emission, focusing on upconversion quantum yield (UCQY) and UV emission. UCQY values of 2.46 % at 250 W cm-2 are achieved with 14.5 nm SrLuF@CaF2 particles, with 7.3 % of total emission in the UV. In 10.9 nm SrYbF1 %Tm3+ @CaF2 particles, UV emission increased to 9.9 % with UCQY at 1.14 %. We demonstrate dye degradation under NIR illumination using SrYbF1 %Tm3+ @CaF2 , highlighting the efficiency of these UCNPs and their ability to trigger photoprocesses.Amino acids (AAs) are key structural motifs with widespread applications in organic synthesis, biochemistry, and material sciences. Recently, with the development of milder and more versatile radical-based procedures, the use of strategies relying on radical chemistry for the synthesis and modification of AAs has gained increased attention, as they allow rapid access to libraries of novel unnatural AAs containing a wide range of structural motifs. In this Minireview, we provide a broad overview of the advancements made in this field during the last decade, focusing on methods for the de novo synthesis of α-, β-, and γ-AAs, as well as for the selective derivatisation of canonical and non-canonical α-AAs.Jacobsen syndrome (MIM #147791) is a rare multisystem genomic disorder involving craniofacial abnormalities, intellectual disability, other neurodevelopmental defects, and terminal truncation of chromosome 11q, typically deleting ~170 to >340 genes. We describe the first case of Jacobsen syndrome caused by congenital chromoanasynthesis, an extreme form of complex chromosomal rearrangement. Six duplications and five deletions occurred on one copy of chromosome 11q with microhomology signatures in the breakpoint junctions, indicating an all-at-once replication-based rearrangement mechanism in a gametocyte or early post-zygotic cell. Eighteen genes were deleted from the Jacobsen region, including KIRREL3, which is associated with intellectual disability.Batesian mimicry, in which harmless organisms resemble unpalatable or harmful species, is a well-studied adaptation for predation avoidance. The females of some Batesian mimic species comprise mimetic and nonmimetic individuals. Mimetic females of such polymorphic species clearly have a selective advantage due to decreased predation pressure, but the selective forces that maintain nonmimetic females in a population remain unclear. In the swallowtail butterfly, Papilio polytes, female polymorphism is controlled by the H (mimetic) and h (nonmimetic) alleles at a single autosomal locus. Here, we examined whether the dominant H allele has a deleterious effect on the pre-adult survival rate (egg-to-adult emergence rate). We repeated an assortative mating-like treatment-that is breeding of males and females whose mothers had the same phenotype (mimetic or nonmimetic)-for three consecutive generations, while avoiding inbreeding. Results showed that pre-adult survival rate decreased over generations only in lines derived from mothers with the mimetic phenotype (hereafter, mimetic-assorted lines). This lowered survival was due to an increased mortality at the final instar larval stage and the pupal stages. Interestingly, the pre-adult mortality in the mimetic-assorted lines seemed to be associated with a male-biased sex ratio at adult emergence. Decitabine DNA Methyltransferase inhibitor These results suggest that the dominant H allele displays a mildly deleterious effect that is expressed more strongly in females and homozygous individuals than in heterozygous individuals. We propose that this cost of mimicry in larval and pupal stages contributes to the maintenance of female-limited polymorphism in P. polytes.The development of novel materials with effective defect-repairing properties will help avoid subtotal gastrectomy in patients with large gastric perforations. We prepared perfused decellularized gastric matrix (PDGM) and analyzed its components, spatial structure, biomechanics, cytotoxicity, and histocompatibility to validate its efficacy in the repair of gastric perforation. PDGM retained large amounts of gastric extracellular matrix, while residual glandular cells and muscle fibers were not found. The spatial structure of the tissue was well preserved, while the DNA and glycosaminoglycan contents were significantly decreased compared with normal gastric tissue (p  less then  .01). There was no obvious deformation of the spatial structure and tissue elasticity of PDGM after sterilization by Cobalt-60 irradiation. The PDGM had good histocompatibility. PDGM was then used to repair a rat gastric perforation model. Radiography of the upper gastrointestinal tract at 24 hr postoperatively revealed no contrast agent leakage.
