Spatial-Related Sensors Matters: 3D Human Motion Reconstruction Assisted with Textual Semantics
Leveraging wearable devices for motion reconstruction has emerged as an
economical and viable technique. Certain methodologies employ sparse Inertial
Measurement Units (IMUs) on the human body and harness data-driven strategies
to model human poses. However, the reconstruction of motion based solely on
sparse IMUs data is inherently fraught with ambiguity, a consequence of
numerous identical IMU readings corresponding to different poses. In this
paper, we explore the spatial importance of multiple sensors, supervised by
text that describes specific actions. Specifically, uncertainty is introduced
to derive weighted features for each IMU. We also design a Hierarchical
Temporal Transformer (HTT) and apply contrastive learning to achieve precise
temporal and feature alignment of sensor data with textual semantics.
Experimental results demonstrate our proposed approach achieves significant
improvements in multiple metrics compared to existing methods. Notably, with
textual supervision, our method not only differentiates between ambiguous
actions such as sitting and standing but also produces more precise and natural
motion.Comment: Accepted by AAAI 202
A Biographical Look into Arthur Miller’s Understanding of Wives and Mothers
The article attempts to examine Arthur Miller’s biographical background especially his mother, his wives and the other women around him and investigate his relationship with them in order to gain a better understanding of the wife and mother figures in Miller’s plays. Seen from the more general background, Miller’s particular outlook on wives and mothers is influenced greatly by his biographical background. His mother’s struggle with his father and her desire for knowledge as well as her courage and strength in the economic crisis, together with his own three marriages, especially his tremulous life with the sex symbol Marilyn Monroe and also all the other women around him all contribute to his shaping of authentic and complex wife and mother images in his plays.Key words: Arthur Miller; Understanding; Mothers; Wive
YhjX Regulates the Growth of Escherichia coli in the Presence of a Subinhibitory Concentration of Gentamicin and Mediates the Adaptive Resistance to Gentamicin
The mechanisms of adaptive resistance of Escherichia coli to aminoglycosides remain unclear. Our RNA-Seq study found that expression of yhjX was markedly upregulated during initial exposure to subinhibitory concentrations of gentamicin. The expression of yhjX was then downregulated dramatically during a second exposure to gentamicin compared to the first exposure. YhjX encodes a putative transporter of the major facilitator superfamily, which is known to be the sole target of the YpdA/YpdB two-component system, the expression of which is highly and specifically induced by pyruvate. To investigate the effect of yhjX on the adaptive resistance of E. coli, in the present study, we constructed yhjX deletion and complemented strains of E. coli ATCC25922. Changes in extracellular pyruvate levels of wide-type and yhjX mutant were measured to determine whether YhjX functions as a pyruvate transporter. The results showed that yhjX deletion improved the growth of E. coli in medium containing subinhibitory concentrations of gentamicin. The yhjX deletion mutant did not exhibit adaptive resistance to subinhibitory concentrations of gentamicin. YhjX might not function as a pyruvate efflux pump in E. coli but was associated with the decrease following a sharp increase in the extracellular pyruvate level. Our findings indicate that yhjX regulates the growth of E. coli in the presence of a subinhibitory concentration of gentamicin and mediates the adaptive resistance to gentamicin
Ivermectin induces apoptosis of esophageal squamous cell carcinoma via mitochondrial pathway
Background: Esophageal squamous cell carcinoma (ESCC) is the most predominant primary malignant tumor among worldwide, especially in China. To date, the successful treatment remains a mainly clinical challenge, it is imperative to develop successful therapeutic agents.
Methods: The anti-proliferative effect of ivermectin on ESCC is investigated in cell model and in nude mice model. Cell apoptosis was assessed using flow cytometry, TUNEL assay and western blotting. Mitochondrial dysfunction was determined by reactive oxygen species accumulation, mitochondrial membrane potential and ATP levels.
Results: Our results determined that ivermectin significantly inhibited the proliferation of ESCC cells in vitro and in vivo. Furthermore, we found that ivermectin markedly mediated mitochondrial dysfunction and induced apoptosis of ESCC cells, which indicated the anti-proliferative effect of ivermectin on ESCC cells was implicated in mitochondrial apoptotic pathway. Mechanistically, ivermectin significantly triggered ROS accumulation and inhibited the activation of NF-ÎşB signaling pathway and increased the ratio of Bax/Bcl-2.
Conclusions: These finding indicated that ivermectin has significant anti-tumour potential for ESSC and may be a potential therapeutic candidate against ESCC
Case report: Donor-derived CLL-1 chimeric antigen receptor T-cell therapy for relapsed/refractory acute myeloid leukemia bridging to allogeneic hematopoietic stem cell transplantation after remission
BackgroundExplore the efficacy and safety of donor-derived CLL-1 chimeric antigen receptor T-cell therapy (CAR-T) for relapsed/refractory acute myeloid leukemia (R/R AML) bridging to allogeneic hematopoietic stem cell transplantation (allo-HSCT) after remission.Case presentationAn adult R/R AML patient received an infusion of donor-derived CLL-1 CAR-T cells, and the conditioning regimen bridging to allo-HSCT was started immediately after remission on day 11 after CAR-T therapy upon transplantation. Then, routine post-HSCT monitoring of blood counts, bone marrow (BM) morphology, flow cytometry, graft-versus-host disease (GVHD) manifestations, and chimerism status were performed.ResultAfter CAR-T therapy, cytokine release syndrome was grade 1. On day 11 after CAR-T therapy, the BM morphology reached complete remission (CR), and the conditioning regimen bridging to allo-HSCT started. Leukocyte engraftment, complete donor chimerism, and platelet engraftment were observed on days +18, +23, and +26 post-allo-HSCT, respectively. The BM morphology showed CR and flow cytometry turned negative on day +23. The patient is currently at 4 months post-allo-HSCT with BM morphology CR, negative flow cytometry, complete donor chimerism, and no extramedullary relapse/GVHD.ConclusionDonor-derived CLL-1 CAR-T is an effective and safe therapy for R/R AML, and immediate bridging to allo-HSCT after remission may better improve the long-term prognosis of R/R AML
