This research addresses the critical issue of cryptojacking attacks, a significant cybersecurity threat where malicious actors covertly exploit computational resources for unauthorized cryptocurrency mining, particularly in wireless sensor networks (WSN) and Internet of Things (IoT) devices. The article proposes an innovative approach that integrates time series analysis with graph neural networks (GNNs) to forecast/detect cryptojacking attack trends within these vulnerable ecosystems. Utilizing the "Cryptojacking Attack Timeseries Dataset," the proposed method emphasizes early detection and predictive insights to anticipate emerging attack patterns.

Small extracellular vesicles (sEVs) isolated from plasma of lung transplant recipients (LTRs) with chronic lung allograft dysfunction (CLAD) contain increased levels of lung associated self-antigens, Kα1 tubulin and collagen V, and decreased expression of the tumor suppressor liver kinase B1 (LKB1). In this study, sEVs were isolated from plasma collected from LTRs with or without cystic fibrosis (CF) from multiple centers at the onset of CLAD and 6 and 12 months before clinical diagnosis of CLAD (n = 32) as well as from time-matched stable controls (n = 25). sEVs were analyzed for Kα1 tubulin, collagen V, and LKB1 by western blot.

Antibody-mediated rejection (AMR) in lung transplantation has been associated with poor long-term clinical course and is a risk factor for chronic lung allograft dysfunction and graft loss. Appropriate management of AMR is necessary to improve graft survival in lung transplant recipients. There is currently no standardized approach to the treatment of lung AMR, and practices vary by institution.

Introduction: Anti-thymocyte globulin (ATG) is a polyclonal antibody formulation which has been used as a second-line therapy for chronic lung allograft dysfunction (CLAD). Limited data exist evaluating its efficacy; however, several single-center retrospective studies have variably demonstrated either improvement or stabilization of spirometry parameters after administration of ATG. ATG has been in use at UT Southwestern for treatment of CLAD since at least 2010; here, we seek to evaluate the effectiveness of this intervention at our center.

The formation of antibodies against donor human leukocyte antigens poses a challenging problem both for donor selection as well as postoperative graft function in lung transplantation. These donor-specific antibodies limit the pool of potential donor organs and are associated with episodes of antibody-mediated rejection, chronic lung allograft dysfunction, and increased mortality. Optimal management strategies for clearance of DSAs are poorly defined and vary greatly by institution; most of the data supporting any particular strategy is limited to small-scale retrospective cohort studies.
