Hereditary Unilateral Hearing difficulties: Qualities along with Etiological Analysis in 121 Patients.

onsistent with previous reports, these data highlight the high frequency of suicidal behaviors in hEDS patients as well as the importance to explore psychopathology in those affected in order to identify vulnerable individuals and provide specific support.HIGHLIGHTSAttempted suicide in patients with hEDS is not uncommon.Age and the presence of psychopathology are associated with suicide attempt in hEDS patients.Personality disturbances and lifetime anxiety disorders predicted suicide attempted in this sample.Purpose To determine the association of monocyte-to-high-density lipoprotein ratio (MHR) and neutrophil-to-lymphocyte ratio (NLR) with diabetic macular edema (DME) and early anti-VEGF treatment response.Material methods This was a retrospective and cross-sectional study conducted with 143 patients with diabetes mellitus (53 diabetic retinopathy with DME, 38 diabetic retinopathy without DME, and 52 without diabetic retinopathy).Results 13.9 was the best cutoff value to predict DME for MHR, and 2 was for NLR (59% and 75% sensitivity and 81% and 59% specificity, respectively). Logistic regression analysis showed that NLR≥2 and MHR≥13.9 were significantly associated with DME prediction. However, neither NLR≥2 nor MHR≥13.9 was associated with central retinal thickness(CRT) or best corrected visual acuity(BCVA) outcomes after anti-VEGF treatment. On the other hand, increased NLR was associated with inferior CRT outcomes.Conclusion MHR and NLR were simple and cost-effective biomarkers to predict DME. Moreover, higher NLR may contribute to poor CRT outcomes.

The objective of the current study was to investigate whether mindfulness and self-compassion are negatively associated with engagement in non-suicidal self-injury (NSSI) and whether emotion dysregulation would mediate this relation.

343 participants (82.2% female;



= 23.98;

 = 7.47) were recruited from university and community settings, and completed online questionnaires. Two groups of participants were created those with lifetime engagement in NSSI (

 = 153) and a comparison group with no prior engagement in NSSI (

 = 190).

First, two one-way MANOVAs revealed significant mean differences (NSSI/comparison) across the self-compassion dimensions and specific mindfulness facets. Second, logistic regressions revealed that the self-coldness dimension of self-compassion significantly predicted engagement in NSSI, and specific mindfulness facets (nonjudging and acting with awareness) were found to negatively predict NSSI engagement. Lastly, mediation analyses revealed that emotion dysregulation fullyey aspects of mindfulness and self-compassion as healthier and kinder alternatives to coping with dysregulated emotions.HighlightsMindfulness and self-compassion significantly differ between NSSI/comparison groupsKey mindfulness facets and self-compassion dimensions negatively predict engagement in NSSIEmotion dysregulation fully mediates self-coldness and mindfulness with NSSI group status.Research on the pretesting effect has shown that attempting to retrieve or generate information, even when unsuccessful, can potentiate the subsequent learning and remembering of that information. link= see more In the current research, we tested the hypothesis that when information can be accessed online, people may be less likely to retrieve or generate information on their own, thus making them less likely to benefit from the pretesting effect. link2 The results of two experiments failed to provide support for this hypothesis. Participants remembered pretested information better than non-pretested information regardless of whether they were required to attempt to retrieve answers from memory or search for the answers using Google. The results suggest that the benefits of pretesting can be observed even when people rely on the internet to answer the questions they encounter.Vaccination has had tremendous impact on human health. The tendency to hesitate or delay vaccination has been increasing, which has contributed to outbreaks of vaccine-preventable diseases. This cross-sectional study aimed to investigate the prevalence of childhood vaccine hesitancy and social media misconceptions in vaccine refusal among randomly selected parents from October 2019 through March 2020 in the outpatient clinics of King Khalid University Hospital, Riyadh, Saudi Arabia. The data were collected using a three-part questionnaire the socio-demographic and economic questions, the Parents' Attitudes about Childhood Vaccines (PACV) survey, and questions concerning social media use. Based on the PACV survey tool, 37 parents (11%) scored a value > 50 and were suggested as hesitant (8% hesitant and 3% very hesitant). Overall, 288 parents (89%) scored less then 50, hence deemed to not be hesitant about childhood vaccination. There was no significant association between high educational level or social media exposure with vaccine hesitancy. The most commonly used social media platform was Twitter (40%). see more In conclusion, we report a low prevalence of vaccine hesitancy about childhood vaccination among parents, with no significant impact of education level or social media on vaccine hesitancy. Further studies are required to replicate these findings in other regions and cities to generalize these observations for Saudi Arabia.Purpose/Objectives to evaluate new onset uveitis or reactivated uveitis by biologic agents and characterize their features.Materials and Methods This is a multicenter, retrospective case series. see more link2 Patients under biologic therapy were included if they developed uveitis for the first time or experienced intraocular inflammation which was different in location or laterality to previous inflammation.Results Sixteen patients were identified. The underlying disorders included ankylosing spondylitis, juvenile idiopathic arthritis, rheumatoid arthritis, and Behçet's Disease. The biologic agents associated with a first episode of uveitis (n = 11) or with a new recurrence of uveitis (n = 5) were etanercept, adalimumab, abatacept, infliximab, and golimumab. Sarcoidosis based on bihilar lymphadenopathy, other computer tomography-findings, or biopsy was diagnosed in five patients under therapy with etanercep, adalimumab, and abatacept. Additionally, seven patients developed clinical changes in their uveitis pattern, suggesting sarcoid uveitis.Conclusions Biologic treatment-induced uveitis often presents as granulomatous disease.We report the incorporation of substitutional Mn atoms in high-quality, epitaxial graphene on Cu(111), using ultralow-energy ion implantation. We characterize in detail the atomic structure of substitutional Mn in a single carbon vacancy and quantify its concentration. In particular, we are able to determine the position of substitutional Mn atoms with respect to the Moiré superstructure (i.e., local graphene-Cu stacking symmetry) and to the carbon sublattice; in the out-of-plane direction, substitutional Mn atoms are found to be slightly displaced toward the Cu surface, that is, effectively underneath the graphene layer. Regarding electronic properties, we show that graphene doped with substitutional Mn to a concentration of the order of 0.04%, with negligible structural disorder (other than the Mn substitution), retains the Dirac-like band structure of pristine graphene on Cu(111), making it an ideal system in which to study the interplay between local magnetic moments and Dirac electrons. Our work also establishes that ultralow-energy ion implantation is suited for substitutional magnetic doping of graphene. Given the flexibility, reproducibility, and scalability inherent to ion implantation, our work creates numerous opportunities for research on magnetic functionalization of graphene and other two-dimensional materials.Strychnine is the prototypic antagonist of glycine receptors, a family of pentameric ligand-gated ion channels. Recent high-resolution structures of homomeric glycine receptors have confirmed the presence of five orthosteric binding sites located in the extracellular subunit interfaces of the receptor complex that are targeted by strychnine. link3 Here, we report the synthesis and extensive pharmacological evaluation of bivalent ligands composed of two strychnine pharmacophores connected by appropriate spacers optimized toward simultaneous binding to two adjacent orthosteric sites of homomeric α1 glycine receptors. In all bivalent ligands, the two strychnine units were linked through C-2 by amide spacers of various lengths ranging from 6 to 69 atoms. Characterization of the compounds in two functional assays and in a radioligand binding assay indicated that compound 11a, with a spacer consisting of 57 atoms, may be capable of bridging the homomeric α1 GlyRs by simultaneous occupation of two adjacent strychnine-binding sites. The findings are supported by docking experiments to the crystal structure of the homomeric glycine receptor. Based on its unique binding mode, its relatively high binding affinity and antagonist potency, and its slow binding kinetics, the bivalent strychnine analogue 11a could be a valuable tool to study the functional properties of glycine receptors.We study nuclear quantum effects in H/D sticking to graphene, comparing scattering experiments at near-zero coverage with classical, quantized, and transition-state calculations. The experiment shows H/D sticking probabilities that are indistinguishable from one another and markedly smaller than those expected from a consideration of zero-point energy shifts of the chemisorption transition state. Inclusion of dynamical effects and vibrational anharmonicity via ring-polymer molecular dynamics (RPMD) yields results that are in good agreement with the experimental results. RPMD also reveals that nuclear quantum effects, while modest, arise primarily from carbon and not from H/D motion, confirming the importance of a C atom rehybridization mechanism associated with H/D sticking on graphene.It was recently found that extremely large plasticity is exhibited in bulk compression of single-crystal ZnS in complete darkness. Such effects are believed to be caused by the interactions between dislocations and photoexcited electrons and/or holes. However, methods for evaluating dislocation behavior in such semiconductors with small dimensions under a particular light condition had not been well established. Here, we propose the "photoindentation" technique to solve this issue by combining nanoscale indentation tests with a fully controlled lighting system. The quantitative data analyses based on this photoindentation approach successfully demonstrate that the first pop-in stress indicating dislocation nucleation near the surface of ZnS clearly increases by light irradiation. Additionally, the room-temperature indentation creep tests show a drastic reduction of the dislocation mobility under light. Our approach demonstrates great potential in understanding the light effects on dislocation nucleation and mobility at the nanoscale, as most advanced technology-related semiconductors are limited in dimensions.Extracellular vesicles (EVs) are nano-sized lipid bilayer encapsulated particles with a molecular cargo that appears to play important roles within the human body, such as in cell-to-cell communication. Unraveling the composition of EV cargos remains one of the most fundamental steps toward understanding the role of EVs in intercellular communication and the discovery of new biomarkers. One of the unmet needs in this field is the lack of a robust, sensitive, and multiplexed method for EV mRNA profiling. We established a new protocol using the NanoString low RNA input nCounter assay by which the targeted mRNA transcripts in EVs can be efficiently and specifically amplified and then assayed for 770 mRNAs in one reaction. Prostate cancer cells with epithelial (PC3-Epi) or mesenchymal (PC3-EMT) phenotypes and their progeny EVs were analyzed by the same panel. Among these mRNAs, 157 were detected in PC3-Epi EVs and 564 were detected in PC3-EMT EVs. link3 NOTCH1 was the most significantly abundant mRNA transcripts in PC3-EMT EVs compared to PC3-Epi EVs.
