ALX1‐related frontonasal dysplasia results from defective neural crest cell development and migration

A pedigree of subjects presented with frontonasal dysplasia (FND). Genome sequencing and analysis identified a p.L165F missense variant in the homeodomain of the transcription factor ALX1 which was imputed to be pathogenic. Induced pluripotent stem cells (iPSC) were derived from the subjects and differentiated to neural crest cells (NCC). NCC derived from ALX1L165F/L165F iPSC were more sensitive to apoptosis, showed an elevated expression of several neural crest progenitor state markers, and exhibited impaired migration compared to wild‐type controls. NCC migration was evaluated in vivo using lineage tracing in a zebrafish model, which revealed defective migration of the anterior NCC stream that contributes to the median portion of the anterior neurocranium, phenocopying the clinical presentation. Analysis of human NCC culture media revealed a change in the level of bone morphogenic proteins (BMP), with a low level of BMP2 and a high level of BMP9. Soluble BMP2 and BMP9 antagonist treatments were able to rescue the defective migration phenotype. Taken together, these results demonstrate a mechanistic requirement of ALX1 in NCC development and migration.
Predatory gastropod drill holes in upper miocene cold seep bivalves, Hokkaido, Japan

Many drilled specimens of Calyptogena pacifica and Conchocele bisecta were obtained from the upper Miocene Morai Formation in western Hokkaido. Thirty-three specimens of C. pacifica (19.8%) and four specimens of C. bisecta (9.3%) were drilled. This is the first report of drilling of cold seep bivalves by either fossil or Recent predatory gastropods. The shape of the holes suggests they appear to have been drilled by the co-occurring naticids Euspira and Cryptonatica. Only two holes might have been drilled by muricids. Almost all holes were completed other than two incomplete holes. Thus, effectiveness of armor (number of incomplete holes/total number of holes) is very low (0.06).
It's surprisingly nice to hear you: Misunderstanding the impact of communication media can lead to suboptimal choices of how to connect with others.

Positive social connections improve wellbeing. Technology increasingly affords a wide variety of media that people can use to connect with others, but not all media strengthen social connection equally. Optimizing wellbeing, therefore, requires choosing how to connect with others wisely. We predicted that people's preferences for communication media would be at least partly guided by the expected costs and benefits of the interaction-specifically, how awkward or uncomfortable the interaction would be and how connected they would feel to their partner-but that people's expectations would consistently undervalue the overall benefit of more intimate voice-based interactions. We tested this hypothesis by asking participants in a field experiment to reconnect with an old friend either over the phone or e-mail, and by asking laboratory participants to "chat" with a stranger over video, voice, or text-based media. Results indicated that interactions including voice (phone, video chat, and voice chat) created stronger social bonds and no increase in awkwardness, compared with interactions including text (e-mail, text chat), but miscalibrated expectations about awkwardness or connection could lead to suboptimal preferences for text-based media. Misunderstanding the consequences of using different communication media could create preferences for media that do not maximize either one's own or others' wellbeing.

Not all Fluorination is the Same: Unique Effects of Fluorine Functionalization of Ethylene Carbonate for Tuning Solid-Electrolyte Interphase in Li Metal Batteries.

Li metal batteries (LMB) are crucial for electrifying transportation and aviation. Engineering electrolytes to form desired solid-electrolyte interphase (SEI) is one of the most promising approaches to enable stable long-lasting LMBs. Among the liquid electrolytes explored, fluoroethylene carbonate (FEC) has seen great success in leading to desirable SEI properties for enabling stable cycling of LMBs. Given the many facets to desirable SEI properties, numerous descriptors and mechanisms have been proposed. In order to build a detailed mechanistic understanding, we analyze varying degrees of fluorination of the same prototype molecule, chosen to be ethylene carbonate (EC) to tease out the interfacial reactivity at the Li metal/electrolyte. Using density functional theory (DFT) calculations, we study the effect of mono-, di-, tri- and tetra- fluorine substitution of EC on its reactivity with Li surface facets in the presence and absence of Li salt. We find that the formation of LiF at early stage of SEI formation, posited as a desirable SEI component, depends on the F abstraction mechanism rather than the number of fluorine substitution. The best illustration of this is cis- and trans-difluoro EC, where F-abstraction is spontaneous with trans case while the cis case needs to overcome a non-zero energy barrier. Using a Pearson correlation map, we find that the extent of initial chemical decomposition quantified by the associated reaction free energy is linearly correlated with the charge transferred from the Li surface and the number of covalent-like bonds formed at the surface. The effect of salt and the surface facet have a much weaker role on determining the decompositions at the immediate electrolyte/electrode interfaces. Putting all of this together, we find that tetra-FEC could act as high-performing SEI modifier as it leads to a more homogeneous, denser LiF containing SEI. Using this methodology, future investigations will explore -CF3 functionalization and other backbone molecules (linear carbonates).
The operating conditions framework: Integrating mechanisms and moderators in health behavior interventions.

Efficacious translational research in health psychology relies on specifying why intervention strategies change health behaviors and when, for what behaviors, and for whom, do these strategies promote change. Whereas interventions' mechanism of action (the why question) has attracted considerable attention, there is a need to conceptualize and integrate factors that moderate intervention effectiveness. Intervention effects on health behaviors are a function of 2 change processes: how effectively interventions change mechanisms of action (target engagement), and how effectively those mechanisms change behavior (target validity). We outline the Operating Conditions Framework (OCF) to articulate theoretical linkages between mechanisms and moderators and begin the process of specifying circumstances that promote target engagement and target validity. A review of 46 meta-analyses of behavioral interventions offers impetus for the OCF by revealing that heterogeneity of effect sizes is frequent, substantial, and largely unexplained in traditional moderator analyses. We present an approach to moderation grounded on the distinction between 2 foci-engagement moderation and validity moderation-and reveal that little is known about variation in how interventions change targets and how changing targets promotes behavior change. The OCF addresses this need by maintaining researchers' focus on mechanisms of behavior change but doing so while embracing the conditional nature of these processes. Because the OCF prioritizes consideration of contextual factors at the outset of a research program, early-phase translational research will be critical in specifying operating conditions and, ultimately, generating guidelines regarding why, when, for whom, and for what behaviors are intervention strategies effective.

Sleep, caregiver burden, and life satisfaction in Parkinson’s disease caregivers: a multinational investigation

Abstract Purpose The primary aim of this study was to examine the pattern of associations among PD patient and caregiver sleep problems, caregiver burden, and caregiver life satisfaction. A secondary aim was to assess whether the pattern of associations differed between Mexican and U.S. caregivers. Materials and methods Analyses were performed on data obtained from 253 caregivers (M age = 59.92). A composite score was produced for caregiver and patient sleep problems. The Zarit Burden Interview and Satisfaction with Life Scale measured caregiver burden and life satisfaction, respectively. A structural equation model with an invariance design was developed to examine and compare the pattern of associations. Results The model was generally invariant across U.S. and Mexican caregivers. Three significant indirect effects were found: caregiver sleep problems were negatively associated with life satisfaction via caregiver burden (p = 0.003); PD patient sleep problems were positively related to caregiver burden via caregiver sleep problems (p = 0.005) and life satisfaction via caregiver burden and caregiver sleep problems (p = 0.002). Conclusions PD patient sleep problems were associated with caregiver sleep problems, leading to increased burden in caregivers and poorer life satisfaction. The findings highlight a potential opportunity for empirically supported sleep interventions. Implications for rehabilitation Parkinson’s disease is a progressive neurological condition that impacts patient and caregiver quality of life. Patient sleep problems contribute to greater caregiver burden, sleep problems, and reduced life satisfaction. The findings suggest patient and caregiver sleep may be a worthwhile target for intervention in order to reduce risk of caregiver burden and improve life satisfaction.

Foi utilizado na area experimental o corte total da alfafa, deixando-se a area totalmente livre de vegetacao, o que propiciou imediata reducao do numero de pulgoes e rapida recuperacao desta populacao apos o rebrote das plantas.
Structural insights into human acid-sensing ion channel 1a inhibition by snake toxin mambalgin1

Acid-sensing ion channels (ASICs) are proton-gated cation channels that are involved in diverse neuronal processes including pain sensing. The peptide toxin Mambalgin1 (Mamba1) from black mamba snake venom can reversibly inhibit the conductance of ASICs, causing an analgesic effect. However, the detailed mechanism by which Mamba1 inhibits ASIC1s, especially how Mamba1 binding to the extracellular domain affects the conformational changes of the transmembrane domain of ASICs remains elusive. Here, we present single-particle cryo-EM structures of human ASIC1a (hASIC1a) and the hASIC1a-Mamba1 complex at resolutions of 3.56 and 3.90 Å, respectively. The structures revealed the inhibited conformation of hASIC1a upon Mamba1 binding. The combination of the structural and physiological data indicates that Mamba1 preferentially binds hASIC1a in a closed state and reduces the proton sensitivity of the channel, representing a closed-state trapping mechanism.
Fluviibacter phosphoraccumulans gen. nov., sp. nov., a polyphosphate-accumulating bacterium of Fluviibacteraceae fam. nov., isolated from surface river water.

Three aerobic, Gram-stain-negative, non-motile, rod-shaped bacteria, designated as strains SHINM1T, ICHIJ1 and ICHIAU1, were isolated from surface river water (Saitama Prefecture, Japan). Phylogenetic analyses based on 16S rRNA and 40 marker gene sequences revealed that the strains formed a distinct phylogenetic lineage within the order Rhodocyclales. The three strains shared 100 % 16S rRNA gene similarity. Growth occurred at 15-30 °C and pH 6.0-9.5, but not in the presence of ≥1.0 % (w/v) NaCl. The isolates stained positive for intracellular polyphosphate granules. The major cellular fatty acids were C16 : 0, summed feature 2 (C12 : 1 aldehyde and/or iso-C16 : 1 I and/or C14 : 0 3-OH), summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c) and summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c). The major polar lipids were phosphatidylethanolamine and an unidentified phospholipid. The predominant quinone system of strain SHINM1T was ubiquinone-8 and its DNA G+C content was 56.7 mol%. Genome sequencing of the three isolates revealed a genome size of 2.29-2.43 Mbp and average nucleotide identity by orthology values of ≥98.9 %. Based on the results of phenotypic and phylogenetic analyses, strains SHINM1T, ICHIJ1 and ICHIAU1 represent a novel species of a new genus, for which the name Fluviibacter phosphoraccumulans gen. nov., sp. nov. is proposed, within a new family, Fluviibacteraceae fam. nov. of the order Rhodocyclales. The type strain is SHINM1T (=JCM 32071T=NCIMB 15105T).
Lactobacillus rhamnosus GG and Biochemical Agents Enrich the Shelf Life of Fresh-Cut Bell Pepper (Capsicum annuum L. var. grossum (L.) Sendt)

This work analyzed the individual and combined effects of biochemical additives and probiotic strain Lactobacillus rhamnosus GG on red and yellow fresh-cut bell pepper (R- and Y-FCBP, respectively) stored at two different temperatures (4 °C and 15 °C) for 15 days. The results revealed that the combined application of biochemical additives and L. rhamnosus GG inhibited the colonization of total bacterial counts (25.10%), total Salmonella counts (38.32%), total Listeria counts (23.75%), and total fungal counts (61.90%) in FCBP. Total bacterial colonization was found to be higher in R-FCBP (1188.09 ± 9.25 CFU g−1) than Y-FCBP (863.96 ± 7.21 CFU g−1). The storage at 4 °C was prevented 35.38% of microbial colonization in FCBP. Importantly, the L. rhamnosus GG count remained for up to 12 days. Moreover, the combined inoculation of the biochemical additives and L. rhamnosus GG treatments (T3) maintained the quality of R- and Y-FCBP for up to 12 days at 4 °C without any loss of antioxidant properties. This work reports the successful utilization of L. rhamnosus GG as a preservative agent for maintaining the quality of FCBP by preventing microbial colonization.
A revision of the genus Psammogorgia Verrill, 1868 (Cnidaria, Anthozoa, Octocorallia) in the tropical eastern Pacific Ocean

Abstract The species of the genus Psammogorgia Verrill, 1868 from the shallow waters of the tropical eastern Pacific were mainly described from 1846 to 1870. Very few contributions were published subsequently. Recently, the genus was revisited with the addition of two new species. However, a comprehensive generic study is still missing for the eastern Pacific. Psammogorgia is characterised by having axes cores without mineralisation, mainly coarse irregular spindles and thorny, leafy or tuberculate clubs coenenchymal sclerites and the anthocodial armature with distinct collaret and points arrangements. Herein a taxonomic revision of the genus is presented based on type material which was morphologically analysed and illustrated using optical and scanning electron microscopy. Comparative character tables are provided for comparison among species in the genus, along with a taxonomic key. Moreover, the taxonomic status of each species was analysed. The genus Psammogorgia comprises six valid species and two varieties, and three lectotypes and a new combination are proposed to establish the taxonomic status of these species.
Volatile Terpenoids from Water Pepper (Polygonum punctatum) Against Pseudomonas aeruginosa and Staphylococcus aureus Virulence Strategies

Polygonum punctatum Elliot (water pepper) is a pungent herb ancestrally employed as a disinfectant in traditional medicine by Toba Indians of the north-eastern region of Argentina and also commonly used as spice in Japanese cuisine. GC-MS of whole diethyl ether extract (EE) from aerial parts allowed to identify 14 volatile terpenoids such as sesquiterpenes: α-bisabolol (3.4 %), polygodial and isotadeonal (34.0%); various methylated phenol like α- tocopherol or vitamin E (3.6 %), and phytosterols: stigmasterol (2.1%) and β-sitosterol (29.9 %). Thus, water pepper is a promising source of drimane sesquiterpenes and phytoestrogens with important bioactivities. Following a taste- guided fractionation by CC and HPLC, drimane-type sesquiterpenes, polygodial (1) and its stereoisomer isotadeonal (2) were isolated as main compounds from the EE. The antipathogenic effects on the bacterial growth, biofilm formation, and elastase activity of both pure compounds and EE were evaluated against two Staphylococcus aureus and two Pseudomonas aeruginosa strains at 10 and 100 µg/mL. The highest effects were observed for the non pungent drimane isotadeonal (2) which was able to reduce about 75 % the bacterial growth of all tested microorganisms and to inhibit Gram-positive biofilm formation (85 % mean) at 100 µg/mL. In addition, elastase activity of P. aeruginosa, another virulence strategy, was attenuated more than 50 % at 100 µg/mL by 2. These results provide evidence that support the antimicrobial use of P. punctatum against P. aeruginosa and S. aureus, as well as, demonstrating that isotadeonal (2), despite it has been suggested to lack biological properties, is a bioactive compound able to control biofilm formation and bacterial growth of both human pathogens.
RegQCNET: Deep quality control for image-to-template brain MRI affine registration

Affine registration of one or several brain image(s) onto a common reference space is a necessary prerequisite for many image processing tasks, such as brain segmentation or functional analysis. Manual assessment of registration quality is a tedious and time-consuming task, especially in studies comprising a large amount of data. Automated and reliable quality control (QC) becomes mandatory. Moreover, the computation time of the QC must be also compatible with the processing of massive datasets. Therefore, automated deep neural network approaches have emerged as a method of choice to automatically assess registration quality. In the current study, a compact 3D convolutional neural network, referred to as RegQCNET, is introduced to quantitatively predict the amplitude of an affine registration mismatch between a registered image and a reference template. This quantitative estimation of registration error is expressed using the metric unit system. Therefore, a meaningful task-specific threshold can be manually or automatically defined in order to distinguish between usable and non-usable images. The robustness of the proposed RegQCNET is first analyzed on lifespan brain images undergoing various simulated spatial transformations and intensity variations between training and testing. Secondly, the potential of RegQCNET to classify images as usable or non-usable is evaluated using both manual and automatic thresholds. During our experiments, automatic thresholds are estimated using several computer-assisted classification models (logistic regression, support vector machine, Naive Bayes and random forest) through cross-validation. To this end we use an expert’s visual QC estimated on a lifespan cohort of 3953 brains. Finally, the RegQCNET accuracy is compared to usual image features such as image correlation coefficient and mutual information. The results show that the proposed deep learning QC is robust, fast and accurate at estimating affine registration error in the processing pipeline.
Characterization of A Herpes-like Virus Isolated from Cultured Japanese Eels in Taiwan

The present paper describes a herpes-like virus, tentatively designated as EHVF (Eel Herpesvirus in Formosa), isolated from diseased Japanese eels (Anguilla japonica Temminck & Schlegel) in Taiwan.This virus had DNA as its nucleic acid, sensitive to ether and chloroform, and resistant to freezing and thawing treatments. Enveloped mature viral particle measured 200 nm in diameter with nucleocapsid of 120 nm.The virus successfully replicated in CCF, CCT, TO-2, BGK, DK-1 and EO-2 cell lines at temperatures from 15°C to 33°C (optimal temperature 24°C). When these cells were infected with EHVF, syncytium formations were observed in CCF, CCT, TO-2, BGK, EK-1 and EO-2 cell lines. However, HeLa, Vero, L, AF, AK, BF-2, CCG, CCO, CF, CHH-1, CHSE-214, EPC, FHM, FS, JF, LF, MH and RTG-2 cell lines were refractory to the multiplication of this virus.No mortalities were observed among eels injected with EHVF, but the virus was reisolated from the kidneys and livers of infected eels 60 days after injection. On the other hand, carp injected with EHVF showed 37% mortality during 60 days and the virus was reisolated from all the dead fish and 84% of the survivors.
Valorization of Sweet Lime Peel for the Extraction of Essential Oil by Solvent Free Microwave Extraction Enhanced with Ultrasound Pretreatment

Essential oils of sweet lime peel, a waste by-product in the juice industry, were extracted using the vacuum assisted solvent free microwave extraction (VASFME) method. The effects of microwave output power (500–1000 W) and extraction time (20–30 min) on the essential oils yield and antimicrobial property were investigated. Optimal conditions were observed at 797.844 W microwave output power and 30 min extraction time. The essential oils yield and antimicrobial property under these conditions were 0.792 ± 0.03% and 18.25 ± 1.45 mm, respectively, which agrees with the predicted values of 0.757% and 16.50 mm. The essential oils were extracted at optimized conditions and analyzed through GCMS for compound identification. A total of 49 compounds were identified, with limonene content (43.47%) being the highest among all sweet lime peel oil compounds. Moreover, the sweet lime peels were subjected to ultrasound pre-treatment before microwave extraction. The ultrasound pre-treatment helped to increase the essential oils yield from 0.84 to 1.06% as the treatment time increased from 30 to 90 min. The increase in yield was 37.66% more compared to VASFME at 90 min treatment time.
Molecular Signaling Pathways and Essential Metabolic Elements in Bone Remodeling: An Implication of Therapeutic Targets for Bone Diseases.

Bone is one of the dynamic tissues in the human body that undergoes continuous remodelling through subsequent actions of bone cells, osteoclasts, and osteoblasts. Several signal transduction pathways are involved in the transition of mesenchymal stem cells into osteoblasts. These primarily include Runx2, ATF4, Wnt signaling and sympathetic signalling. The differentiation of osteoclasts is controlled by M-CSF, RANKL, and costimulatory signalling. It is well known that bone remodelling is regulated through receptor activator of nuclear factor-kappa B ligand followed by the binding to RANK, which eventually induces the differentiation of osteoclasts. The resorbing osteoclasts secrete TRAP, cathepsin K, MMP-9 and gelatinase to digest the proteinaceous matrix of type I collagen and form a saucer-shaped lacuna along with resorption tunnels in the trabecular bone. Osteoblasts secrete a soluble decoy receptor, osteoprotegerin that prevents the binding of RANK/RANKL and thus moderating osteoclastogenesis. Moreover, bone homeostasis is also regulated by several growth factors, cytokines, calciotropic hormones, parathyroid hormone and sex steroids. The current review presents a correlation of the probable molecular targets underlying the regulation of bone mass and the role of essential metabolic elements in bone remodelling. Targeting these signaling pathways may help design newer therapies for treating bone diseases.
