Rb/E2f and DREAM complexes play vital roles in regulating cell cycle progression. To date, how they coordinate their functions to regulate cell cycle-dependent gene expression is not clear. Here, we identified a long noncoding RNA (lncRNA), which we named , that bridges the interaction between E2f1 and the dREAM complex to regulate endoreplication specifically in salivary gland.

Objective: To construct a model for predicting recidivism in violence in community-based schizophrenia spectrum disorder patients (SSDP) by adopting a joint modeling method.

Methods: Based on the basic data on severe mental illness in Southwest China between January 2017 and June 2018, 4565 community-based SSDP with baseline violent behaviors were selected as the research subjects.

Background: Despite the importance of medication adherence in treatment effectiveness, little is known about the association between medication non-adherence and self-inflicted violence behaviors. We aimed to assess whether medication non-adherence increased the risk of self-inflicted violence behaviors among schizophrenics in communities (hypothesis 1) and whether the dose-response relationship existed (hypothesis 2).

Methods: This 12-year cohort study in western China recruited 292,667 community-dwelling schizophrenics.

Article Synopsis
  • The study examined medication adherence and risky behaviors among schizophrenia patients in western China over a 13-year period, involving 292,667 participants.
  • Results showed that 31.4% of patients had good medication adherence, whereas 68.6% had poor adherence, which correlated with increased risky behaviors like minor nuisances and self-harm.
  • The findings indicate that poor medication adherence is linked to higher risks of certain risky behaviors, but it surprisingly associates with a lower risk of completed suicide compared to those with good adherence.

Previous studies found that both oral and topical administration of enzymatic digestion products < 3 K Da ultrafiltration fractions of Pinctada martensii mantle (PMPs) had pro-healing effects. Thus, we further purified them by Sephadex-G25 and screened them by cellular assays to obtain Pinctada martensii purified peptides (PMPPs). In this study, we explored the mechanism of PMPPs on wound healing by in vivo, in vitro, and in silico experiments.
