Prediction of prognosis in patients with nontraumatic intracranial hemorrhage using blood urea nitrogen-to-creatinine ratio on admission: a retrospective cohort study based on data from the medical information Mart for intensive care-IV database.

Background: The blood urea nitrogen-to-creatinine ratio (BUNCR) has been proposed as a potential biomarker for critical illness-induced catabolism. However, its specific relevance and significance in the context of non-traumatic intracranial hemorrhage (NTIH) remains unclear. As such, the primary objective of this study was to determine the role of BUNCR in the prognosis of patients with NTIH.

CRL4 negatively regulates IL-23 production in dendritic cells and limits the development of psoriasis.

The E3 ligase CRL4 is believed to be a pivotal regulator of the cell cycle and is required for mitotic and S phase progression. The NEDD8-targeting drug MLN4924, which inactivates cullin ring-finger ubiquitin ligases (CRLs), has been examined in clinical trials for various types of lymphoma and acute myeloid leukemia. However, the essential role of CRL4 in primary myeloid cells remains poorly understood.

Effects of MEK inhibitor U0126 on meiotic progression in mouse oocytes: microtuble organization, asymmetric division and metaphase II arrest.

In this study we used U0126, a potent and specific inhibitor of MEK, to study the roles of MEK/ERK/p90rsk signaling pathway in the meiotic cell cycle of mouse oocytes. The phosphorylation of MAP kinase and p90rsk in the oocytes treated with 1.5 microM U0126 was the same as that in oocytes cultured in drug-free medium.

[Roles of protein kinase C in mouse oocyte maturation and fertilization in vitro].

Protein kinase C is an important family of serine/threorine protein kinase. In this experiment the possible roles of PKC in meiotic maturation, fertilization and egg activation were studied in mouse oocytes. Two isoforms of PKC, PKC alpha and beta 1, were localized in mouse oocytes.
