Intrathecal or intraventricular antimicrobial therapy for post-neurosurgical Gram-negative bacillary meningitis or ventriculitis: a systematic review and meta-analysis.

Purpose: Extensively-drug-resistant Gram-negative bacteria (XDR GNB)-related post-neurosurgical infection is closely related to mortality, which represents a major challenge for neurosurgeons. There is an urgent need to review and evaluate methods to reduce mortality.

Methods: Both international and Chinese databases were searched independently from their inception to 15 June 2023.

Sensitive and Portable Detection of Bacteria Using Exonuclease-III (Exo-III) Assisted Signal Amplification and Personal Glucose Meters.

Despite major advances in combating pathogenic bacteria caused infection, infectious diseases remain a major cause of death today. A variety of bacteria detection approaches have been established by exploiting the aptamer to specifically identify target. However, these methods require specific equipment or laboratory based instruments, which is expensive and not easily available to the public.

SOX7 is involved in polyphyllin D-induced G0/G1 cell cycle arrest through down-regulation of cyclin D1.

The incidence of mortality of prostate cancer (PCa) has been an uptrend in recent years. Our previous study showed that the sex-determining region Y-box 7 (SOX7) was low-expressed and served as a tumor suppressor in PCa cells. Here, we describe the effects of polyphyllin D (PD) on proliferation and cell cycle modifications of PCa cells, and whether SOX7 participates in this process.

Downregulated NOX4 underlies a novel inhibitory role of microRNA-137 in prostate cancer.

Prostate cancer is the second highest caused by cancer-related death among males. microRNAs (miRs) have been reported to participate in carcinogenesis, yet their roles in prostate cancer are rarely studied or investigated. Therefore, the present study attempted to explore the effect of miR-137 in prostate cancer via regulating NADPH oxidase 4 (NOX4).

The heterogeneity of cell subtypes from a primary culture of human amniotic fluid.

Heterogeneous human amniotic fluid contains various cell types. Herein, we report on the possibility of simultaneously isolating three subtypes of cells from one primary culture. Using a stainless steel instrument named a colony poculum, two of the three cell subtypes could be efficiently cultured, and these were further characterized.
