Study on Removal Effect and Mechanism in Ecological Floating-Beds

工程科学与技术, 2009
:Based on comparative tests of removal effect between Ecological Floating-Beds (EFBs) planted with Canna indica and Acorus calamus and the unplanted bed, the mechanism of EFBs was investigated through the tracer study and mass balance calculation ...

A Unified Drift–Flux Framework for Predictive Analysis of Flow Patterns and Void Fractions in Vertical Gas Lift Systems

Fluids
This study utilizes the drift–flux model to develop a new flow pattern map designed to facilitate an accurate estimation of gas void fraction (αg) in vertical upward flow. The map is parameterized by mixture velocity (um) and gas volumetric quality (βg),

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Study on the Improvement of Flow Pattern of Rest Pools of Vertical Slot Fishway

Renmin Zhujiang, 2020
Rest pools provide a rest place for migratory fish to swim upstream,so whether its flow pattern is reasonable or not directly affects the upstream efficiency of fish.Based on the design principle of the mainstream centered in the pool,this paper builds a
