INTRODUCTION The aim of the current cross-sectional study was to examine the role of social-cognitive processing in the relation between violence exposure at home and child-to-parent violence. METHODS The study included 1,624 adolescents (54.9% girls) aged between 12 and 18 years (Mage = 14.7, SD = 1.7 years) from Jaén and Oviedo (Spain) who completed a set of questionnaires about violence exposure, child-to-parent violence and social-cognitive processing. RESULTS The data revealed that exposure to violence at home is related to dysfunctional components of social-cognitive processing, and that whereas some of these components (anger and aggressive response access) are positively related to child-to-parent violence motivated by reactive reasons, other components (anticipation of positive consequences and justification of violence) are positively related to the instrumental use of the aggression against parents. CONCLUSIONS More prevention work is needed with children exposed to violence at home to reduce the risk of intergenerational transmission of violence. Moreover, treatment programs should include intervention on the way in which adolescents process the information in their interactions with parents. These interventions must be focused on different components of social-cognitive processing, depending on whether these aggressive behaviors are motivated by reactive or instrumental reasons. Nanomaterials with integrated multiple imaging and therapeutic modalities possess great potentials in accurate cancer diagnostics and enhanced therapeutic efficacy. Traditional strategies for achieving multimodality nanoplatform through one by one combination of different modalities are challenged by the complicated structural design and fabrication as well as inherent incompatibility between different modalities. Herein, a novel strategy is presented to realize multimodal imaging and synergistic therapy using a class of simple silver core/AIE (aggregation-induced emission) shell nanoparticles. In addition to the intrinsic AIE fluorescence (FL) and metal-based computed tomography (CT) and radiation therapy (RT) properties, an extra functionality at the core/shell interface was identified to enable excellent photothermal (PT) and photoacoustic (PA) performance. AZD-5153 6-hydroxy-2-naphthoic supplier As a result, five imaging and therapy modalities (FL, CT, PA, photothermal therapy (PTT), and RT) were achieved with a single structural unit for sensitive tumor imaging and effective therapy. Functional proteins are essential for the regulation of cellular behaviors and have found growing therapeutic uses. However, low bioavailability of active proteins to their intracellular targets has been a long-standing challenge to achieve their full potential for cell reprogramming and disease treatment. Here we report mesoporous polydopamine (mPDA) with a built-in plasmonic nanoparticle core as a multifunctional protein delivery system. The mPDA with a unique combination of large surface area, metal-chelating property, and broad-spectrum photothermal transduction allows efficient loading and near-infrared light-triggered release of functional proteins, while the plasmonic core serves as a photostable tracer and fluorescence quencher, collectively leading to real-time monitoring and active cytosolic release of model proteins. In particular, controlled delivery of cytotoxic ribonuclease A has shown excellent performance in invivo cancer therapy. The possibility of coating mPDA on a broad range of functional cores, thanks to its universal adhesion, provides opportunities for developing tailored delivery carriers of biologics to overcome intrinsic biological barriers. Magnesium (Mg)-based metals can be used as next-generation fracture internal fixation devices due to their specific properties. We used vascularized bone grafting fixed by degradable pure Mg screws and obtained satisfactory results in the treatment of osteonecrosis of the femoral head. However, the mechanical properties of these screws make them weaker than those made of traditional metals. In particular, one of the main challenges of using screws made of Mg-based metals is their application in fixation at important weight-bearing sites in the human body. Femoral neck fracture is a common clinical injury. In this injury, the large bearing stress at the junction requires a fixation device with extremely high mechanical strength. Surgery and appropriate internal fixation can accelerate the healing of femoral neck fractures. Traditional internal fixation devices have some disadvantages after surgery, including stress shielding effects and the need for secondary surgery to remove screws. On the basis of previous work, we developed high-strength pure Mg screws for femoral neck fractures. In this study, we describe the first use of high-purity Mg to prepare large-size weight-bearing screws for the fixation of femoral neck fractures in goats. We then performed a 48 weeks follow-up study using in vivo transformation experiments. The results show that these biodegradable high-purity Mg weight-bearing screws had sufficient mechanical strength and a degradation rate compatible with bone repair. Furthermore, good bone formation was achieved during the degradation process and reconstruction of the bone tissue and blood supply of the femoral head and femoral neck. This study provides a basis for future research on the clinical transformation of biodegradable high-purity Mg weight-bearing screws. The objective of this study was to investigate the molecular characteristics and horizontal transfer of florfenicol resistance gene-related sequences in Proteus strains isolated from animals. A total of six Proteus strains isolated from three farms between 2015 and 2016 were screened by polymerase chain reaction (PCR) for known florfenicol resistance genes. Proteus cibarius G11, isolated from the fecal material of a goose, was found to harbor both cfr and floR genes. Whole genome sequencing revealed that the strain harbored two copies of the floR gene one was located on the chromosome and the other was located on a plasmid named pG11-152. Two floR-containing fragments 4028 bp in length were identical and showed transposon-like structures. The cfr gene was found on a plasmid named pG11-51 and flanked by a pair of IS26s. Thus, mobile genetic elements played an important role in floR replication and horizontal resistance gene transfer. Therefore, increasing attention should be paid to monitoring the spread of resistance genes and resistance in real time.
