Such N-doped carbon with bimetallic alloy bonds provides new pathways for the rational creation of high-efficiency energy conversion and storage equipment.

To date, studies have not explored whether a dual diagnosis of aphasia plus apraxia of speech (AOS) versus aphasia alone (APH) affects the response to language-based naming treatments.

To compare the effects of semantic feature analysis (SFA) treatment for individuals with APH versus aphasia plus AOS, and to test if the presence of AOS impacted the effects of treatment.

A non-randomized experimental group study was conducted to explore the treatment, generalization and maintenance effects between the AOS and APH groups. Participants included nine individuals with aphasia and 11 with concomitant aphasia and AOS. Dependent measures included lexical accuracy, number of sound-level distortions, and lexical stress and syllable segmentation errors.

Both groups showed significantly improved naming accuracy of trained items for up to 2 months post-treatment. Improvement on naming accuracy of untrained items post-treatment, both semantically related and unrelated to trained items, was lower in magnitude. That ends to respond well to treatments focused on articulatory-kinematic aspects of speech movement. What this paper adds to the existing knowledge This study compares the effects of SFA in a group of individuals with aphasia alone and a group with similar severity of aphasia but with concomitant AOS, ranging from mild to moderate-severe. Overall, AOS did not have a negative effect on response to the treatment. What are the potential or actual clinical implications of this work? Individuals with aphasia plus AOS can be expected to benefit to a similar degree from SFA as people with aphasia alone. It is likely that the use of practice principles of high intensity, random stimulus presentation and varied practice are important components of the protocol.Recently, extensive efforts have been directed at finding novel 2D-layered structures with anisotropic crystal structures. Herein, the in-plane anisotropic optical and (photo)electrical properties of 2D SiAs nanosheets synthesized using a solid-state reaction and subsequent mechanical exfoliation are reported. The angle-resolved polarized Raman spectrum shows high in-plane anisotropy of the phonon vibration modes, which are consistent with the theoretical prediction. Field-effect transistor devices fabricated using the SiAs nanosheets demonstrate significant anisotropy in the hole mobility with an anisotropic ratio as high as 5.5. Photodetectors fabricated with single SiAs nanosheet exhibit high sensitivity in the UV-visible region, and the anisotropic ratio of the photocurrent reaches 5.3 at 514.5 nm and 2.3 at 325 nm. This work lays the foundation for future research in anisotropic 2D materials.Thin endometrium is a primary cause of failed embryo transfer, resulting in long-term infertility and negative family outcomes. While hormonal treatments have greatly improved fertility results for some women, these responses remain unsatisfactory due to damage and infection of the complex endometrial microenvironment. In this study, a multifunctional microenvironment-protected exosome-hydrogel is designed for facilitating endometrial regeneration and fertility restoration via in situ microinjection and endometrial regeneration. This exosome hydrogel is formulated via Ag+ -S dynamic coordination and fusion with adipose stem cell-derived exosomes (ADSC-exo), yielding an injectable preparation that is sufficient to mitigate infection risk while also possessing the antigenic contents and paracrine signaling activity of the ADSC source cells, enabling regeneration of the endometrial microenvironment. In vitro, this exosome-hydrogel exerts an outstanding neovascularization-promoting effect, increased human umbilical vein endothelial cell proliferation and tube formation for 1.87 and 2.2 folds. In vivo, microenvironment-protected exosome-hydrogel also reveals to promote neovascularization and tissue regeneration while suppressing local tissue fibrosis. Importantly, regenerated endometrial tissue is more receptive to give embryos and birth to a healthy newborn. This microenvironment-protected exosome-hydrogel system offers a convenient, safe, and noninvasive approach for repairing thin endometrium and fertility restoration.

Vitamin K dependent coagulation factor deficiency type 1 (VKCFD1) is a rare hereditary bleeding disorder caused by mutations in γ-glutamyl carboxylase (GGCX). VKCFD1 patients are treated life-long with high doses of vitamin K in order to correct the bleeding phenotype. However, normalization of clotting factor activities cannot be achieved for all VKCFD1 patients.

The current study aims to investigate the responsiveness to vitamin K for all reported GGCX mutations with respect to clotting factors in order to optimize treatment.

This study developed an assay using genetically engineered GGCX

cells, in which GGCX mutations were analyzed with respect to their ability to γ-carboxylate vitamin K dependent pro-coagulatory and anti-coagulatory clotting factors by ELISA. Additionally, factor VII activity was measured in order to proof protein functionality. For specific GGCX mutations immunofluorescent staining was performed to assess the intracellular localization of clotting factors with respect to GGCX wild-type and mutations.

All GGCX mutations were categorized into responder and low responder mutations, thereby determining the efficiency of vitamin K supplementation. Most VKCFD1 patients have at least one vitamin K responsive GGCX allele that is able to γ-carboxylate clotting factors. PRT062607 In few patients, the hemorrhagic phenotype cannot be reversed by vitamin K administration because GGCX mutations on both alleles affect either structural or catalytically important sites thereby resulting in residual ability to γ-carboxylate clotting factors.

With these new functional data we can predict the hemorrhagic outcome of each VKCFD1 genotype, thus recommending treatments with either vitamin K or prothrombin complex concentrate.
