Effect of backwash on the performance of submerged membrane filtration

open access: yes, 2010
碩士本研究旨在探討逆洗的操作條件對沈浸式薄膜過濾效能的影響。以平均孔徑為5.6μm之薄膜過濾粒徑為5μm之聚甲基丙烯酸甲酯(PMMA)粒子為例,探討逆洗時間、逆洗頻率及逆洗通量等操作條件對濾速恢復與逆洗效率的影響。研究結果顯示:在過濾初期,過濾阻力之主要來源是薄膜的阻塞,等到過濾500秒後,則轉變成濾餅過濾模式,但薄膜孔洞阻塞之阻力仍佔總阻力之50%以上。操作在低逆洗通量時,長時間的逆洗比短時間的逆洗更能去除內部阻塞約達23%。比較第一次逆洗的濾速回升率,則在低逆洗通量下,可將濾速提升約39 ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

open access: yesFEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells

open access: yesFEBS Open Bio, EarlyView.
RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

open access: yesFEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

open access: yesFEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Effect of Organic Polarity on Ultrafiltration Membrane Filtration Performance

open access: yes工程科学与技术, 2011
:Deionized water was applied to prepare five kinds of water samples, in which the organics were equivalent in contents, but different in polar components. Ultrafiltration membrane was used to filter the samples.
