Poly(ADP-ribose) polymerase 1 (PARP1) is one of the first responders to DNA damage and plays crucial roles in recruiting DNA repair proteins through its activity - poly(ADP-ribosyl)ation (PARylation). The enrichment of DNA repair proteins at sites of DNA damage has been described as the formation of a biomolecular condensate. However, it remains unclear how exactly PARP1 and PARylation contribute to the formation and organization of DNA repair condensates.

Article Synopsis
  • Synovial sarcoma (SS) is a rare type of cancer, primarily found in genitourinary tissues, commonly linked to the SS18::SSX gene fusion, and its paratesticular occurrence is extremely uncommon, with only 4 documented cases prior to this study.
  • This research details the characteristics and genetic profile of the largest cohort of paratesticular SS patients, analyzing data from 14 individuals aged 15 to 47, all of whom underwent surgical removal of the tumors and some received chemotherapy.
  • The findings indicate a generally poor prognosis for paratesticular SS even after aggressive treatment, emphasizing the need for thorough diagnostic methods to differentiate it from similar conditions, and supporting the use of SS18-SS

Article Synopsis
  • - Reports of antimicrobial resistance have led some clinicians to use alternative wound dressings called DACC-coated dressings, claiming antimicrobial activity despite being non-medicated.
  • - A systematic review was conducted to evaluate the effectiveness of these dressings on chronic wound healing and infection control, using the GRADE framework and PICO format to structure the research.
  • - The review analyzed 748 records, ultimately including 10 relevant studies, but found the overall quality of evidence to be very low, highlighting the need for more rigorous randomized controlled trials for better clarity on DACC-coated dressings.

The elasticity of soft tissues has been widely considered a characteristic property for differentiation of healthy and lesions and, therefore, motivated the development of several elasticity imaging modalities, for example, ultrasound elastography, magnetic resonance elastography, and optical coherence elastography to directly measure the tissue elasticity. This paper proposes an alternative approach of modeling the elasticity for prior knowledge-based extraction of tissue elastic characteristic features for machine learning (ML) lesion classification using computed tomography (CT) imaging modality. The model describes a dynamic non-rigid (or elastic) soft tissue deformation in differential manifold to mimic the tissues' elasticity under wave fluctuation in vivo.

Cardiac output (Q̇) and leg blood flow (Q̇) can be measured simultaneously with high accuracy using transpulmonary and femoral vein thermodilution with a single-bolus injection. The invasive measure has offered important insight into leg hemodynamics and blood flow distribution during exercise. Despite being the natural modality of exercise in humans, there has been no direct measure of Q̇ while running in humans.

Background: The hybrid convergent procedure is approved to treat symptomatic patients with long-standing persistent atrial fibrillation (AF). Despite direct visualization during surgical ablation as well as the use of luminal oesophageal temperature (LET) monitoring, oesophageal injury is still possible. A dedicated device for proactive oesophageal cooling has recently been cleared by the Food and Drug Administration to reduce the likelihood of ablation-related oesophageal injury resulting from radiofrequency cardiac ablation procedures.

In ischaemic stroke, a large reduction in blood supply can lead to the breakdown of the blood-brain barrier and to cerebral oedema after reperfusion therapy. The resulting fluid accumulation in the brain may contribute to a significant rise in intracranial pressure (ICP) and tissue deformation. Changes in the level of ICP are essential for clinical decision-making and therapeutic strategies.

The x-ray radiation dose in computed tomography (CT) examination has been a major concern for patients. Lowing the tube current and exposure time in data acquisition is a straightforward and cost-effective strategy to reduce the x-ray radiation dose. However, this will inevitably increase the noise fluctuations in measured projection data, and the corresponding CT image quality will be severely degraded if noise suppression is not performed during image reconstruction.

Article Synopsis
  • * Nalbuphine resulted in significantly fewer side effects, including less respiratory depression, postoperative nausea and vomiting (PONV), and itching compared to morphine.
  • * Additionally, children receiving nalbuphine had a shorter time for laryngeal mask airway removal than those given morphine, suggesting a quicker recovery.

Background: Pain after cardiac surgery via median sternotomy can be difficult to treat, and if inadequately managed can lead to respiratory complications, prolonged hospital stays and chronic pain.

Objectives: To evaluate available literature and develop recommendations for optimal pain management after cardiac surgery via median sternotomy.

Design: A systematic review using PROcedure-SPECific Pain Management (PROSPECT) methodology.

Background: Hepatocyte growth factor (HGF) is a cytokine linked to incident heart failure (HF), particularly HF with preserved ejection fraction (HFpEF). Increases in left ventricular (LV) mass and concentric remodelling defined by increasing mass-to-volume (M:V) ratios are imaging risk markers for HFpEF. We aimed to determine if HGF is associated with adverse LV remodelling.

Genome-wide association studies identify OsWRKY53 as a key regulator of salt tolerance in rice.

Article Synopsis
  • - Salinity stress negatively impacts plant growth, but rice has developed signaling pathways to combat this issue; however, research into genetic variants for salt tolerance is still limited.
  • - This study identifies ten candidate genes linked to salt tolerance in rice landraces and focuses on two key genes: OsWRKY53 (a transcriptional factor) and OsMKK10.2 (a Mitogen-activated protein Kinase Kinase), which help manage sodium levels in roots.
  • - Findings reveal that OsWRKY53 regulates OsMKK10.2 and represses the sodium transporter OsHKT1;5, contributing to a coordinated defense mechanism against ionic stress and enhancing our understanding of the molecular basis for salt tolerance in plants.

Electronic address:

Photodynamic therapy (PDT) has been used as an alternative or as a complement of conventional approaches for cancer treatment. In PDT, the reactive oxygen species (ROS) produced from the interaction between the photosensitizer (PS), visible light and molecular oxygen, kill malignant cells by triggering a cascade of cytotoxic reactions. In this process, the PS plays an extremely important role in the effectiveness of the therapy.

Introduction: Radiotherapy deliveries with dynamic couch motions that shorten the source-to-axis distance (SAD) on a C-arm linac have the potential to increase treatment efficiency through the increase of the effective dose rate. In this investigation, we convert clinically deliverable volumetric modulated arc therapy (VMAT) and dynamic conformal arc (DCA) plans for cranial radiosurgery into virtual isocenter plans through implementation of couch trajectories that maintain the target at a shortened but variable SAD throughout treatment.

Materials And Methods: A randomly sampled population of patients treated with cranial radiosurgery from within the last three years were separated into groups with one, two, and three lesions.

Objectives: To develop a joint k-TE reconstruction algorithm to reconstruct the T2-weighted (T2W) images and T2 map simultaneously.

Materials And Methods: The joint k-TE reconstruction model was formulated as an optimization problem subject to a self-consistency condition of the exponential decay relationship between the T2W images and T2 map. The objective function included a data fidelity term enforcing the agreement between the solution and the measured k-space data, together with a spatial regularization term on image properties of the T2W images.

Conformation specific antagonistic high affinity antibodies to the RON receptor kinase for imaging and therapy.

The RON receptor tyrosine kinase is an exceptionally interesting target in oncology and immunology. It is not only overexpressed in a wide variety of tumors but also has been shown to be expressed on myeloid cells associated with tumor infiltration, where it serves to dampen tumour immune responses and reduce the efficacy of anti-CTLA4 therapy. Potent and selective inhibitory antibodies to RON might therefore both inhibit tumor cell growth and stimulate immune rejection of tumors.
