Conclusion: B-cell non-Hodgkin's lymphoma (B-NHL) in the head and neck most commonly affected the oropharynx and the cervical lymph node in sexagenarian patients, with more than 70% of these cases being diffuse large B-cell lymphoma (DLBCL). Accordingly, B-NHL should be considered one of the most important differential diagnoses of head and neck malignancies.
Objectives: It has previously been reported that the majority of head and neck malignant lymphomas are B-NHLs. This analysis aimed to assess the site-specific profiles of B-NHL of the head and neck.
Methods: The medical records of patients with B-NHL of the head and neck diagnosed between January 2004 and December 2013 were retrospectively reviewed. The clinical parameters of these patients, including age, sex, site distribution, and histopathologic sub-type, were analyzed.
Results: A total of 153 cases (95 males; 58 females) were included in this analysis (male-to-female ratio = 1.64:1). The patient age at the time of diagnosis ranged from 30-92 years (median = 68 years). The oropharynx was the most commonly affected site (40.5%), followed by the cervical lymph nodes (33.3%). The most common histopathologic sub-type was DLBCL (71.9%), followed by follicular lymphoma (11.1%), and extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (9.2%).

Background: Sleep apnea syndrome (SAS) is associated with hypertension and vascular remodeling. Hypoxia-inducible factor-1α (HIF-1α) and the Hippo-YAP pathway are implicated in these processes, but their specific roles remain unclear. This study investigated the HIF-1α/Hippo-YAP pathway in SAS-related hypertension.

Rationale And Objectives: To evaluate and compare image quality of different energy levels of virtual monochromatic images (VMIs) using standard versus strong deep learning spectral reconstruction (DLSR) on dual-energy CT pulmonary angiogram (DECT-PA).
Materials And Methods: A retrospective study was performed on 70 patients who underwent DECT-PA (15 PE present; 55 PE absent) scans. VMIs were reconstructed at different energy levels ranging from 35 to 200 keV using standard and strong levels with deep learning spectral reconstruction.

Atherosclerotic cardiovascular and cerebrovascular diseases are the number one killer of human health. In view of the important role of mitochondria in the formation and evolution of atherosclerosis, our manuscript aims to comprehensively elaborate the relationship between mitochondria and the formation and evolution of atherosclerosis from the aspects of mitochondrial dynamics, mitochondria-organelle interaction (communication), mitochondria and cell death, mitochondria and vascular smooth muscle cell phenotypic switch, etc., which is combined with genome, transcriptome and proteome, in order to provide new ideas for the pathogenesis of atherosclerosis and the diagnosis and treatment of related diseases.
