Structural dynamics of contractile injection systems. [PDF]

open access: yesBiophys J
The dynamics of many macromolecular machines is characterized by chemically-mediated structural changes that achieve large scale functional deployment through local rearrangements of constitutive protein sub-units. Motivated by recent high resolution structural microscopy of a particular class of such machines, contractile injection systems (CIS), we ...

Genome-wide Identification and Characterization of a Superfamily of Bacterial Extracellular Contractile Injection Systems

open access: yesCell Reports, 2019
Summary: Several phage-tail-like nanomachines were shown to play an important role in the interactions between bacteria and their eukaryotic hosts. These apparatuses appear to represent a new injection paradigm.

Injective Split Systems

open access: yesGraphs and Combinatorics, 2023
AbstractA split system$$\mathcal S$$Son a finite setX,$$|X|\ge 3$$|X|≥3, is a set of bipartitions or splits ofXwhich contains all splits of the form$$\{x,X-\{x\}\}$${x,X-{x}},$$x \in X$$x∈X. To any such split system$$\mathcal S$$Swe can associate the Buneman graph$$\mathcal B(\mathcal S)$$B(S)which is essentially a median graph with leaf-setXthat ...

A versatile injection system for flow‐injection analysis [PDF]

open access: yesJournal of Analytical Methods in Chemistry, 1992
Analyser injection systems based on the principle of flow‐injection analysis depend on the technique used. They generally take the form of an injection loop valve; the injected sample volume is determined by the volume of the valve. Injection systems are seldom designed with a time factor to define this volume.

Endoscopic Management of Vesicoureteral Reflux in Duplex Renal Collecting Systems

open access: yesJournal of Pediatric Research, 2022
Aim:Standardization of an optimal treatment protocol for vesicoureteral reflux (VUR) correlated with duplex kidney systems remains controversial. In this study, we reviewed our experience in endoscopic subureteric injection to correct reflux in duplex ...
