Background Community-based telemedicine screening for diabetic retinopathy (DR) has been highly recommended worldwide. However, evidence from low- and middle-income countries (LMICs) on the choice between artificial intelligence (AI)–based manual grading–based is inadequate policy making. Objective The aim of this study was to test whether AI model more worthwhile than grading in community-based DR context labor costs urban China. Methods We conducted cost-effectiveness cost-utility analyses...

Background: Gallbladder cancer (GBC) is an aggressive and highly lethal biliary tract malignancy, with extremely poor prognosis. In the present study, we analyzed potential involvement of MYBL2, a member Myb transcription factor family, in carcinogenesis human GBC. Methods: MYBL2 expression levels were measured GBC cholecystitis tissue specimens using quantitative real-time PCR (qRT-PCR) immunohistochemical (IHC) assays. The effects on cell proliferation DNA synthesis evaluated Cell Counting...

Gallbladder cancer (GBC) is the most common malignancy in biliary tract. Without effective treatment, its prognosis notoriously poor. Tea polyphenols (TPs) have many pharmacological and health benefits, including antioxidant, anti-inflammatory, anti-tumor, anti-thrombotic, antibacterial, vasodilatory properties. However, anti-cancer effect of TPs human gallbladder has not yet been determined. Cell viability colony formation assay were used to investigate cell growth. cycle apoptosis...

Cell-mediated immunity is often suppressed in patients with hematological malignancies. Recently, we found that low T cell receptor (TCR)-CD3 signaling was related to abnormal expression of the negative regulator nuclear factor kappa B (NF-κB) A20 acute myeloid leukemia. To investigate characteristics immunodeficiency lymphomas, analyzed features and its upstream regulating mucosa-associated lymphoid tissue lymphoma translocation gene 1 (MALT1) genes downstream NF-κB different subtypes,...

Knowledge of the oncogenic signaling pathways T-cell acute lymphoblastic leukemia (T-ALL) remains limited. Constitutive aberrant activation nuclear factor kappa B (NF-κB) pathway has been detected in various lymphoid malignancies and plays a key role development these carcinomas. The zinc finger-containing protein, A20, is central regulator multiple NF-κB-activating cascades. A20 frequently inactivated by deletions and/or mutations several B-and lymphoma subtypes. However, few polymorphisms...
