Balancing reaction-diffusion network for cell polarization pattern with stability and asymmetry [PDF]

eLife 13:RP96421 (2024)
Cell polarization is a critical process that separates molecular species into two distinct regions in prokaryotic and eukaryotic cells, guiding biological processes such as cell division and cell differentiation. Although several underlying antagonistic reaction-diffusion networks capable of setting up cell polarization have been identified ...

Leveraging Anatomical Constraints with Uncertainty for Pneumothorax Segmentation [PDF]

arXiv, 2023
Pneumothorax is a medical emergency caused by abnormal accumulation of air in the pleural space - the potential space between the lungs and chest wall. On 2D chest radiographs, pneumothorax occurs within the thoracic cavity and outside of the mediastinum and we refer to this area as "lung+ space". While deep learning (DL) has increasingly been utilized

Robot‐Assisted Versus Open Surgery for the Resection of Large Thymomas: A Retrospective Cohort Study

Journal of Surgical Oncology, EarlyView.
ABSTRACT Background Robot‐assisted thoracic surgery (RATS) is increasingly becoming the preferred surgical method for the resection of thymomas. We initiated the current study to evaluate perioperative outcomes and early recurrence associated with the surgical approach.

Total Parathyroidectomy with Subcutaneous Parathyroid Forearm Autotransplantation in the Treatment of Secondary Hyperparathyroidism: A Single-Center Experience. [PDF]

, 2018
Introduction Secondary hyperparathyroidism is common in chronic kidney disease. Parathyroidectomy is indicated in refractory hyperparathyroidism when medical treatments and so the parathyroid hormone levels cannot be lowered to acceptable values without

Prediction of Metastasis in Small Pulmonary Oligonodules Detected in Breast Cancer Patients at Baseline CT

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT It is challenging for radiologists to diagnose pulmonary metastases when they encounter only a few (n ≤ 5) small pulmonary nodules (< 10 mm) on staging CT in breast cancer patients. We conducted this study to assess clinical and imaging features related to metastasis for better risk stratification.

Interleukin 7 from Maternal Milk Crosses the Intestinal Barrier and Modulates T- Cell Development in Offspring [PDF]

, 2011
Background Breastfeeding protects against illnesses and death in hazardous environments, an effect partly mediated by improved immune function. One hypothesis suggests that factors within milk supplement the inadequate immune response of the offspring,

Association of SIRT6 Expression With Risk of Pneumonitis Induced by Radiotherapy in Cancer Patients

Molecular Carcinogenesis, EarlyView.
ABSTRACT Thoracic tumours represent a significant proportion of malignant cancers. While radiotherapy (RT) improves prognosis, it can also lead to side effects such as radiation‐induced pneumonitis (RP). Since SIRT6 is involved in DNA repair, energy metabolism and inflammation, this study aims to investigate the expression of SIRT6 in lymphocytes as a ...

Initial ultrasound evaluation of an anterior mediastinal mass ultimately diagnosed as T-cell acute lymphoblastic leukemia: a report of three cases in children

Radiology Case Reports, 2022
Pediatric T-cell acute lymphoblastic leukemia (T-ALL) in the anterior mediastinum has an acute onset and requires early treatment. The diagnostic strategy for anterior mediastinal masses in pediatric patients usually involves imaging evaluation, surgical

Undescended retropharyngeal parathyroid adenoma with adjacent thymic tissue in a 13-year-old boy with primary hyperparathyroidism. [PDF]

, 2019
We describe a rare presentation of a symptomatic parathyroid adenoma located in an ectopic retropharyngeal position in a 13-year-old boy. Preoperative CT scan and MRI demonstrated the ectopic location of the parathyroid adenoma.
