Surgical approaches to intramedullary spinal cord astrocytomas in the age of genomics

Frontiers in Oncology, 2022
Intramedullary astrocytomas represent approximately 30%–40% of all intramedullary tumors and are the most common intramedullary tumor in children. Surgical resection is considered the mainstay of treatment in symptomatic patients with neurological ...

Liver Resection for Primary Hepatic Neoplasms. [PDF]

, 1988
Subtotal hepatic resection was performed in 356 patients; 87 had primary hepatic malignancies, 108 had metastatic tumors, and 161 had benign lesions including 8 traumatic injuries. The global mortality was 4.2%.

Application value of contrast‐enhanced ultrasound in preoperative localization of microwave ablation for primary hyperparathyroidism

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Background Ultrasonography (US) and 99mTechnetium‐sestamibi scintigraphy (99mTc‐MIBI) are currently first‐line imaging modalities to localize parathyroid adenomas with sensitivities of 80% and 84%, respectively. Therefore, finding other modalities to further improve the diagnostic accuracy for preoperative localization is critically needed ...

DNA resection in eukaryotes: deciding how to fix the break [PDF]

, 2010
DNA double-strand breaks are repaired by different mechanisms, including homologous recombination and nonhomologous end-joining. DNA-end resection, the first step in recombination, is a key step that contributes to the choice of DSB repair.

Algebra and Geometry of Camera Resectioning [PDF]

arXiv, 2023
We study algebraic varieties associated with the camera resectioning problem. We characterize these resectioning varieties' multigraded vanishing ideals using Gr\"obner basis techniques. As an application, we derive and re-interpret celebrated results in geometric computer vision related to camera-point duality.

Prognostic impact of Lymph node resection in stage II colon cancer: a prospective study from a tertiary hospital center [PDF]

Romanian Medical Journal, 2022
Background. The treatment of stage II colon cancer has been a subject of debate for a long time. In the last years, a few risk factors have been proposed in order to guide any treatment decision more accurately. One of these risk factors is the number of

RESECT-SEG: Open access annotations of intra-operative brain tumor ultrasound images [PDF]

arXiv, 2022
Purpose: Registration and segmentation of magnetic resonance (MR) and ultrasound (US) images play an essential role in surgical planning and resection of brain tumors. However, validating these techniques is challenging due to the scarcity of publicly accessible sources with high-quality ground truth information.
