The dynamics of neuronal systems are characterized by hallmark features such as oscillations and synchrony. However, it has remained unclear whether these characteristics are epiphenomena or are exploited for computation. Due to the challenge of selectively interfering with oscillatory network dynamics in neuronal systems, we simulated recurrent networks of damped harmonic oscillators in which oscillatory activity is enforced in each node, a choice well supported by experimental findings.

Background: We performed an umbrella review to synthesize evidence on the effects of physical activity (PA) interventions on indicators of physical and psychological health among children and adolescents, including body mass index (BMI), blood pressure (BP), depressive symptoms, and cognitive function.
Methods: PubMed, Embase, Web of Science, and the Cochrane Library were systematically searched from inception through 31 July 2023. We included meta-analyses of randomized controlled trials exploring the effects of PA interventions on BMI, BP, depressive symptoms, or cognitive function in healthy or general children and adolescents.

Background: The treatment of relapsed/refractory T cell acute lymphoblastic leukemia (R/R T-ALL) is a significant challenge in hematologic oncology, and no standard salvage treatment plan exists. Both Chinese and international clinical guidelines recommend combination chemotherapy including venetoclax.
Methods: Efficacy and safety of venetoclax, azacitidine, homoharringtonine, cytarabine, and aclarubicin (VA-HAA) combination therapy were retrospectively analyzed in 3 patients with R/R T-ALL at the Department of Hematology, 920th Hospital of the Joint Logistics Support Force, Chinese People's Liberation Army.
