Versatile vector tools for efficient protein screening across multiple expression systems

FEBS Open Bio, EarlyView.
A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

Unconventional prosthodontics: Post, core and crown technique

The Journal of Indian Prosthodontic Society, 2007
Background and Objective: Endodontically treated teeth, over-zealously prepared teeth, teeth with crowns seated on carious dentin, secondary spread of decay underneath an existing crown or trauma - all these can lead to partial or complete coronal fractures of the teeth with or without damage to the existing prosthetic crowns. Clinicians often have to

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

FEBS 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 ...

Restoring an Extremely Destructed Tooth with Flared Root Canal Walls: A Case Report

Frontiers in Dentistry
Restoring severely damaged teeth has always been challenging when the remaining crown structure is limited, and retention might be necessary from the root canal using intracanal posts.

Evaluating the involvement of autolysosomes in the nuclear translocation of fluorescent proteins

FEBS Open Bio, EarlyView.
Endogenously expressed fluorescent proteins can be degraded by autophagy and transported to cell nuclei via the nuclear pore complex. But in some cell lines, for example, HeLa cells which are positive for immunoreactivity of a receptor ligand, such as UCN I, in cell nuclei, fusion of autolysosome with the nuclear envelope is involved in the nuclear ...

EFFECT OF TYPE AND CEMENTATION METHOD OF POST-CORE ON MICROLEAKAGE

, 1994
The restorations of the severely damaged teeth by post core have been increased with the developement of endodontic procedures. But high failure rates of these procedures being reported, various restorative modifications were induced for successful ...
