A HER2-targeted antibody-novel DNA topoisomerase I inhibitor conjugate induces durable adaptive antitumor immunity by activating dendritic cells.

We designed and developed a novel DNA topoisomerase I inhibitor MF-6, which was a more potent cytotoxin and a more potent inducer of immunogenic cell death compared with DXd. To utilize MF-6's ability to induce antitumor immunity, a human epidermal growth factor receptor 2 (HER2)-targeted antibody-drug conjugate (ADC) trastuzumab-L6 that included a cleavable linker and MF-6 was developed. Different from traditional cytotoxic ADC, the antitumor activity of trastuzumab-L6 was assessed by inducing tumor cell immunogenic cell death, activating dendritic cells and cytotoxic CD8+ T cells to acquire durable adaptive immune memory.

Muscle synergies for evaluating upper limb in clinical applications: A systematic review.

Introduction: Muscle synergies have been proposed as a strategy employed by the central nervous system to control movements. Muscle synergy analysis is a well-established framework to examine the pathophysiological basis of neurological diseases and has been applied for analysis and assessment in clinical applications in the last decades, even if it has not yet been widely used in clinical diagnosis, rehabilitative treatment and interventions. Even if inconsistencies in the outputs among studies and lack of a normative pipeline including signal processing and synergy analysis limit the progress, common findings and results are identifiable as a basis for future research.

Nanocarrier of Pin1 inhibitor based on supercritical fluid technology inhibits cancer metastasis by blocking multiple signaling pathways.

Cancer metastasis is the primary cause of all cancer-related deaths due to the lack of effective targeted drugs that simultaneously block multiple signaling pathways that drive the dissemination and growth of cancer cells. The unique proline isomerase Pin1 activates numerous cancer pathways, but its role in cancer metastasis and the inhibitory efficacy of Pin1 inhibitors on cancer metastasis are unknown. Moreover, the applicability of Pin1 inhibitor-all- retinoic acid (ATRA) is limited due to its several drawbacks.

Biomimetic human eyes in adaptive lenses with conductive gels.

To investigate the imaging effect, adaptive robust lenses are prepared by sealing transparent liquid or gel. Lenses are fabricated using the negative-pressure method, which is a benefit for a stable biconvex shape. Under the action of an electric field, the soft lens deforms following the dielectric elastomer actuator (DEA).

Exploiting the size exclusion effect of protein adsorption layers for electrochemical detection of microRNA: A new mechanism for design of E-DNA sensor.

The assay performance of electrochemical DNA (E-DNA) sensors is deeply influenced by the state of DNA probes immobilized on electrode. Moreover, the immobilization procedures for DNA probes are tedious and vary according to the probes and analytes. In this work, we find that the adsorption layers of bovine serum albumin (BSA) on gold electrode (AuE) possess a size exclusion effect to distinguish between single-stranded (-ss) DNA probes and the DNA fragments generated from enzymatic digestion of ssDNA probes.

Number of trials and data structure affect the number and components of muscle synergies in upper-limb reaching movements.

Due to the variability of human movements, muscle activations vary among trials and subjects. However, few studies investigated how data organization methods for addressing variability impact the extracted muscle synergies.Fifteen healthy subjects performed a large set of upper limb multi-directional point-to-point reaching movements.

Influence of Intellectual-cultural Orientation as Family Culture on Chinese College Students' Subjective Well-being: A Moderation Model.

The well-known mediation-moderation model of subjective well-being has been criticized because it oversimplified the concept of culture. This study aimed to explore whether the family culture, as supplement of social culture, has significant impacts on subjective well-being. The intellectual-cultural orientation subscale (ICO) of family environment scale-CV (FES-CV), Eysenck personality questionnaire for adult (EPQA), and index of well-being (IWB) were used to test 340 college students from China.

Evaluation of Methods for the Extraction of Spatial Muscle Synergies.

Muscle synergies have been largely used in many application fields, including motor control studies, prosthesis control, movement classification, rehabilitation, and clinical studies. Due to the complexity of the motor control system, the full repertoire of the underlying synergies has been identified only for some classes of movements and scenarios. Several extraction methods have been used to extract muscle synergies.

Spectrum Analysis Enabled Periodic Feature Reconstruction Based Automatic Defect Detection System for Electroluminescence Images of Photovoltaic Modules.

Electroluminescence (EL) imaging is a widely adopted method in quality assurance of the photovoltaic (PV) manufacturing industry. With the growing demand for high-quality PV products, automatic inspection methods based on machine vision have become an emerging area concern to replace manual inspectors. Therefore, this paper presents an automatic defect-inspection method for multi-cell monocrystalline PV modules with EL images.

Intra-Subject and Inter-Subject Movement Variability Quantified with Muscle Synergies in Upper-Limb Reaching Movements.

Quantifying movement variability is a crucial aspect for clinical and laboratory investigations in several contexts. However, very few studies have assessed, in detail, the intra-subject variability across movements and the inter-subject variability. Muscle synergies are a valuable method that can be used to assess such variability.

Structure and SAXS studies unveiled a novel inhibition mechanism of the Pseudomonas aeruginosa T6SS TseT-TsiT complex.

The bacterial type VI secretion system (T6SS) is a powerful arsenal that fires many toxic effectors into neighboring cells to gain advantage over inter-bacterial competition and eukaryotic host infection. Meanwhile, the cognate immunity proteins of these effectors are employed to protect themselves from the virulence. TseT-TsiT is a newly discovered effector-immunity (E-I) protein pair secreted by T6SS of Pseudomonas aeruginosa.

Mechanism type of temporomandibular joint structure is an important factor influencing the performance of the masticatory robot. In view of the wide application of elastic components in the field of the biomimetic robot, an elastic component was adopted to simulate the buffering characteristics of the temporomandibular joint disc and formed the elastic temporomandibular joint structure on the basis of point-contact high pair.

Characterization of the Pseudomonas aeruginosa T6SS PldB immunity proteins PA5086, PA5087 and PA5088 explains a novel stockpiling mechanism.

The bacterial type VI secretion system (T6SS) secretes many toxic effectors to gain advantage in interbacterial competition and for eukaryotic host infection. The cognate immunity proteins of these effectors protect bacteria from their own effectors. PldB is a T6SS trans-kingdom effector in Pseudomonas aeruginosa that can infect both prokaryotic and eukaryotic cells.

Modular Organization of Muscle Synergies to Achieve Movement Behaviors.

Muscle synergy has been applied to comprehend how the central nervous system (CNS) controls movements for decades. However, it is not clear about the motion control mechanism and the relationship between motions and muscle synergies. In this paper, we designed two experiments to corroborate the hypothesis: (1) motions can be decomposed to motion primitives, which are driven by muscle synergy primitives and (2) variations of motion primitives in direction and scale are modulated by activation coefficients rather than muscle synergy primitives.
