In the cut flower market, traditional breeding is still the best way to achieve new rose cultivars. The geographical delocalization of cultivar constitution (generally made in Europe and North America) and plant cultivation (large areas in Africa and South America) represents a limit point for crossing and selection. Rose breeders often need to overcome geographical distances, resulting in asynchrony in flowering among crossing parents, by storing and sending pollen. Hence, a key aspect in breeding programs is linked to pollen availability and conservation, jointly with the identification of parameters related to pollen fertility...

Multichannel receivers are usually employed in high-rate underwater acoustic communication to achieve spatial diversity. In the context of multichannel underwater acoustic communications, passive time reversal (TR) combined with a single-channel adaptive decision feedback equalizer (TR-DFE) is a low-complexity solution to achieve both spatial and temporal focusing. In this paper, we present a novel receiver structure to combine passive time reversal with a low-order multichannel adaptive decision feedback equalizer (TR-MC-DFE) to improve the performance of the conventional TR-DFE...

Breast cancer (BC) is the most frequent tumour affecting women all over the world. In low- and middle-income countries, where its incidence is expected to rise further, BC seems set to become a public health emergency. The aim of the present study is to provide a systematic review of current BC screening programmes in WHO European Region to identify possible patterns. Multiple correspondence analysis was performed to evaluate the association among: measures of occurrence; GNI level; type of BC screening programme; organization of public information and awareness campaigns regarding primary prevention of modifiable risk factors; type of BC screening services; year of screening institution; screening coverage and data quality...

Paclitaxel (PTX) is one of the most effective drugs used in the treatment of esophageal cancer, however, paclitaxel resistance represents a key limitation during the treatment process. In this study, we investigated the changes of Bcl-2 family members in the moderate paclitaxel-resistance of esophageal carcinoma EC109/PTX cells both in vitro and in vivo. Moreover, we evaluated the reversal effect using siRNAs and the recombinant inhibitor TW37 targeting Bcl-2, Bcl-XL and Mcl-1. Our findings show that downregulation of Bcl-2, Bcl-XL and Mcl-1 can significantly promote EC109/PTX cell apoptosis and reduce the EC109/PTX cell resistance index (RI)...

REVIEW
Margaret Mp Pearce
A key pathological hallmark of most neurodegenerative diseases is the misfolding of a particular protein, leading to deposition of toxic protein aggregates in brain tissue. Recent data provide compelling evidence that pathogenic protein aggregates have prion-like properties-they self-replicate by templated misfolding of monomeric proteins and spread between individual cells. Studies in genetic model organisms have expanded our understanding of how prion-like pathogenic aggregates propagate in vivo, revealing potential roles for spreading along neural networks and key cellular processes in both neurons and glial cells...

Although lines of evidence demonstrated that cytokines play an important role in the pathogenesis of major depressive disorder (MDD), none of the them have been established as reliable biomarkers. We use our previous whole-genome cRNA microarray data to identify epithelial cell-derived neutrophil-activating peptide 78 (ENA78), the most differentially expressed cytokine in peripheral blood between MDD patients and healthy controls; and then we confirmed the result by the quantitative reverse transcription-polymerase chain reaction (RT-qPCR) and enzyme-linked immunosorbent assay (ELISA) for mRNA and protein level, respectively, in an independent drug-naïve first-episode sample set...

Inspired from geldanamycin, the synthesis of a new series of 20-membered macrocyclic compounds is developed. The key features in our design are (i) retention of the fragment having the precise chiral functional groups of geldanamycin at C10, C11, C12 and C14, and (ii) replacement of an olefin moiety with the ester group, and the quinoid sub-structure with the triazole ring. The southern fragment needed for the macrocyclic ring formation was obtained from Evans' syn aldol as the key reaction and with the use of D-mannitol as the cheap source of a chiral starting material...

This paper presents the results of a broad-scale survey of resource recovery implementation in Italian wastewater treatment plants (WWTPs). To the best of our knowledge, this is the first survey comprising a large number of WWTPs done in Europe: more than 600 plants were investigated, representing a treated load of around 20 million population equivalent (≈25% of the total in Italy). Conventional and innovative options for both material and energy recovery along the water and sludge line were surveyed, in order to i) offer a real and complete picture of the current state of resource recovery in WWTPs, and ii) underline key aspects and potential areas for improvements, as a baseline for future developments in the direction of more sustainable plants...

Synaptic refinement is a critical step in nervous system maturation, requiring a carefully timed reorganization and refinement of neuronal connections. We have identified myrf-1 and myrf-2, two C. elegans homologs of Myrf family transcription factors, as key regulators of synaptic rewiring. MYRF-1 and its paralog MYRF-2 are functionally redundant specifically in synaptic rewiring. They co-exist in the same protein complex and act cooperatively to regulate synaptic rewiring. We find that the MYRF proteins localize to the ER membrane and that they are cleaved into active N-terminal fragments, which then translocate into the nucleus to drive synaptic rewiring...

The spindle assembly checkpoint kinase Mps1 not only inhibits anaphase but also corrects erroneous attachments that could lead to missegregation and aneuploidy. However, Mps1's error correction-relevant substrates are unknown. Using a chemically tuned kinetochore-targeting assay, we show that Mps1 destabilizes microtubule attachments (K fibers) epistatically to Aurora B, the other major error-correcting kinase. Through quantitative proteomics, we identify multiple sites of Mps1-regulated phosphorylation at the outer kinetochore...

Social anxiety disorder (SAD) and alcohol use disorders (AUD) co-occur frequently and there is preliminary evidence that alcohol might reduce social anxiety. It is, however, unclear which mechanisms contribute to the anxiety reducing effect, particularly regarding key aspects of social anxiety such as deficits in social performance. We compared self-rated and physiological measures of anxiety as well as self- and observer-rated social performance in a sample of 62 individuals with SAD and 60 nonanxious control participants during a speech task after receiving either alcohol, an alcohol-free placebo drink or orange juice...

The present research investigates cultural variation in grounding principles for inferring agency in order to address an important theoretical debate: does cultural diversity in agency concepts reflect an animistic overextension of (universal) folkpsychology, as many have argued, or an alternative theory of folkcommunication based on relational principles? In two experiments, mind perception measures were adapted to assess beliefs concerning the agency of non-animal kinds (plants, abiotic kinds, complex artifacts) among Indigenous Ngöbe adults in Panama and US college students...

Searching experimental feasible two-dimensional (2D) ferromagnetic crystals with large spin-polarization ratio, high Curie temperature and large magnetic anisotropic energy is one key to develop next-generation spintronic nano-devices. Here, 2D Fe2Si nanosheet, one counterpart of Hapkeite mineral discovered in meteorite, with novel magnetism is proposed on the basis of first-principles calculations. 2D Fe2Si crystal has a slightly buckled triangular lattice with planar hexacoordinated Si and Fe atoms. The spin-polarized calculations with hybrid HSE06 function method indicate that 2D Fe2Si is a ferromagnetic half metal at its ground state with 100% spin-polarization ratio at Fermi energy level...

Cytochrome P450 (CYP) 3A5 characterized with polymorphic and extensive expression in multiple tissues is the most important P450 enzyme among the minor CYP3A isoforms. However, a selective and sensitive probe for CYP3A5 remains unavailable. In this study, we identified and characterized a naturally-occurring lignan 12 (Schisantherin E) as an isoform-specific probe for selective detection of CYP3A5 activity in complex biological samples. With thorough characterization including LC-MS and NMR, we found that 12 can be metabolized by CYP3A5 to generate a major metabolite 2-O-demethylated 12...

The oxidation processes of L-Met-(Pro)n-L-Met peptides that contain two Met residues located on the N and C termini and separated by a defined number (n = 0 - 4) of proline residues were investigated in aqueous solutions using laser flash photolysis. The use of such peptides allowed for distance control between the sulfur atoms located in the side chains of the Met residues. Interactions between side chains of the Met residues were probed by the observation of transients with σ*-type 2c-3e (S∴S)(+), (S∴N)(+) and/or (S∴O)(+)-bonds as well as of α-(alkylthio)alkyl radicals (αS)...

Small-molecule drug design is a complex and iterative decision-making process relying on pre-existing knowledge and driven by experimental data. Low molecular weight chemicals represent an attractive therapeutic option as they are readily accessible to organic synthesis and can easily be characterized.1 Their potency, as well as pharmacokinetic and pharmacodynamic properties can be systematically and rationally investigated, and ultimately optimized via expert science behind medicinal chemistry and methods of computer-aided drug design (CADD)...
