Key Laboratory of Luminescence and Optical Information, Ministry of Education, School of Science, Beijing JiaoTong University, Beijing 100044, China.

Combination of the merit of inorganic nanocrystals (NCs) and solution-processed conjugated polymer is a convenient strategy to obtain stable and efficient electroluminescent white-light-emitting diodes (el-WLEDs). In this work, an el-WLED was fabricated on the basis of Cd-free Cu-In-Zn-S (CIZS)/ZnS NCs blending with polyfluorene derivative poly[4-(octyloxy)-9,9-diphenylfluoren-2,7-diyl]--[5-(octyloxy)-9,9-diphenylfluoren-2,7-diyl] (PODPF), which exhibited a stable white light emission with a color rendering index value of 85. Meanwhile, it had a stable spectrum under high voltage due to the extremely weak energy transfer between PODPF and CIZS/ZnS NCs. Read More

Tailoring Highly Ordered Graphene Framework in Epoxy for High-Performance Polymer-Based Heat Dissipation Plates.

ACS Nano 2021 Jul 26. Epub 2021 Jul 26.

Key Laboratory of Marine Materials and Related Technologies, Zhejiang Key Laboratory of Marine Materials and Protective Technologies, Ningbo Institute of Materials Technology and Engineering (NIMTE), Chinese Academy of Sciences, Ningbo 315201, People's Republic of China.

As the power density and integration level of electronic devices increase, there are growing demands to improve the thermal conductivity of polymers for addressing the thermal management issues. On the basis of the ultrahigh intrinsic thermal conductivity, graphene has exhibited great potential as reinforcing fillers to develop polymer composites, but the resultant thermal conductivity of reported graphene-based composites is still limited. Here, an interconnected and highly ordered graphene framework (HOGF) composed of high-quality and horizontally aligned graphene sheets was developed by a porous film-templated assembly strategy, followed by a stress-induced orientation process and graphitization post-treatment.

CAM-DR: Mechanisms, Roles and Clinical Application in Tumors.

Front Cell Dev Biol 2021 6;9:698047. Epub 2021 Jul 6.

Medical School, Nantong University, Nantong, China.

Despite the continuous improvement of various therapeutic techniques, the overall prognosis of tumors has been significantly improved, but malignant tumors in the middle and advanced stages still cannot be completely cured. It is now evident that cell adhesion-mediated resistance (CAM-DR) limits the success of cancer therapies and is a great obstacle to overcome in the clinic. The interactions between tumor cells and extracellular matrix (ECM) molecules or adjacent cells may play a significant role in initiating the intracellular signaling pathways that are associated with cell proliferation, survival upon binding to their ligands.

Orf virus ORF120 protein positively regulates the NF-κB pathway by interacting with G3BP1.

J Virol 2021 Jul 21:JVI0015321. Epub 2021 Jul 21.

Key Laboratory of Zoonosis, Ministry of Education, College of Veterinary Medicine, Jilin University, Changchun, China.

Orf virus (ORFV) is a highly epitheliotropic parapoxvirus with zoonotic significance that induces proliferative lesions in the skin of sheep, goats and humans. Several viral proteins encoded by ORFV, including NF-κB inhibitors, play important roles in hijacking host-associated proteins for viral evasion of the host innate immune response. However, the roles of proteins with unknown functions in viral replication and latent infection remain to be explored. Read More

Histological changes after pulmonary artery banding for retraining of subpulmonary left ventricle.

Ann Thorac Surg 2021 Jul 17. Epub 2021 Jul 17.

Cardiac Registry, Departments of Cardiology, Pathology, and Cardiac Surgery, Boston Children's Hospital, Boston, MA; Department of Pathology, Boston Children's Hospital and Harvard Medical School, Boston, MA.

Background: Patients with congenitally corrected transposition of the great arteries (ccTGA) with intact ventricular septum (IVS) or d-looped transposition of the great arteries (DTGA) with IVS post atrial switch operation often develop left ventricular dysfunction after anatomical repair despite prior retraining of the morphologically left ventricle (mLV) using pulmonary artery banding (PAB). We examined histopathological changes in such mLV.

Methods: Capillary density, myocyte diameter, and interstitial fibrous area in the mLV were retrospectively evaluated in postmortem or explanted heart specimens obtained from patients with ccTGA/IVS or DTGA/IVS post atrial switch operation after PAB for retraining and compared with those of patients with normal cardiac anatomy, ccTGA/IVS or DTGA/IVS without PAB, and ccTGA or DTGA with high mLV pressure using generalized estimating equations models.

Neuroplastin in human cognition: review of literature and future perspectives.

Transl Psychiatry 2021 Jul 16;11(1):394. Epub 2021 Jul 16.

Croatian Institute for Brain Research, School of Medicine, University of Zagreb, Šalata12, 10000, Zagreb, Croatia.

Synaptic glycoprotein neuroplastin is involved in synaptic plasticity and complex molecular events underlying learning and memory. Studies in mice and rats suggest that neuroplastin is essential for cognition, as it is needed for long-term potentiation and associative memory formation. Recently, it was found that some of the effects of neuroplastin are related to regulation of calcium homeostasis through interactions with plasma membrane calcium ATPases. Read More

Ceria Nanozyme-Integrated Microneedles Reshape the Perifollicular Microenvironment for Androgenetic Alopecia Treatment.

ACS Nano 2021 Jul 19. Epub 2021 Jul 19.

Institute of Pharmaceutics, College of Pharmaceutical Sciences, Zhejiang University, Hangzhou 310058, China.

Androgenetic alopecia (AGA) is highly prevalent in current society but lacks effective treatments. The dysregulation of the hair follicle niche induced by excessive reactive oxygen species (ROS) and insufficient vascularization in the perifollicular microenvironment is the leading cause of AGA. Herein, we designed a ceria nanozyme (CeNZ)-integrated microneedles patch (Ce-MNs) that can alleviate oxidative stress and promote angiogenesis simultaneously to reshape the perifollicular microenvironment for AGA treatment.
