Robust and interpretable deep learning system for prognostic stratification of extranodal natural killer/T-cell lymphoma.

Purpose: Extranodal natural killer/T-cell lymphoma (ENKTCL) is an hematologic malignancy with prognostic heterogeneity. We aimed to develop and validate DeepENKTCL, an interpretable deep learning prediction system for prognosis risk stratification in ENKTCL.

Methods: A total of 562 patients from four centers were divided into the training cohort, validation cohort and test cohort.

Single-arm study of camrelizumab plus apatinib for patients with advanced mucosal melanoma.

Background: Previous studies have suggested the potential synergistic antitumor activity when combining immune checkpoint inhibitors with anti-angiogenic agents in various solid tumors. We aimed to assess the efficacy and safety of camrelizumab (a humanized programmed cell death-1 antibody) plus apatinib (a vascular endothelial growth factor receptor tyrosine kinase inhibitor) for patients with advanced mucosal melanoma (MM), and explore-related biomarkers.

Methods: We conducted a single-center, open-label, single-arm, phase II study.

Robust deep learning-based PET prognostic imaging biomarker for DLBCL patients: a multicenter study.

Objective: To develop and independently externally validate robust prognostic imaging biomarkers distilled from PET images using deep learning techniques for precise survival prediction in patients with diffuse large B cell lymphoma (DLBCL).

Methods: A total of 684 DLBCL patients from three independent medical centers were included in this retrospective study. Deep learning scores (DLS) were generated from PET images using deep convolutional neural network architecture known as VGG19 and DenseNet121.

Nicotine Activating αβ Nicotinic Acetylcholine Receptors to Suppress Neuroinflammation via JAK2-STAT3 Signaling Pathway in Ischemic Rats and Inflammatory Cells.

Nicotine plays a role in inhibiting inflammatory factors, which contributes to improving cognitive impairment by activating αβ nAChRs in ischemic rats, but the underlying mechanism has not been fully elucidated. Janus tyrosine kinase 2-signal transducer and activator of transcription 3 (JAK2-STAT3) signaling pathway is involved in cognitive improvement, and there seems to be a relationship between nAChRs and JAK2-STAT3 as well. The aim of this study is to explore the role of JAK2-STAT3 signaling pathway in nicotine-mediated anti-inflammatory effect.

Nicotine Induced Neurocognitive Protection and Anti-inflammation Effect by Activating α 4β 2 Nicotinic Acetylcholine Receptors in Ischemic Rats.

Introduction: The main objective of this study was to explore the mechanism of nicotine improving cognitive impairments in ischemic rats.

Methods: Twenty adult male Sprague-Dawley (SD) rats underwent ischemic model surgery by injecting endothelin-1 into the left thalamus, which were classified into four different groups with different intervention: nicotine (1.5 mg/kg/d), dihydro-β-erythroidine (DHβE; 3 mg/kg/d), nicotine (1.

18F-FDG PET/CT Imaging in an Adolescent Patient With Primary Prostatic Stromal Sarcoma.

Primary prostatic stromal sarcoma is an extremely rare disease that predominantly occurs in adults, accounting for only 0.1% of all prostate cancers. Prostatic stromal sarcoma is quite aggressive and can spread to lung, liver, bone, and other organs.
