Web-based modelling with applications to surgical training [PDF]

open access: yes, 2002
Web-based surgical training has the potential to offer a cheap training platform, accessible from anywhere in the world, at any time. However the use of web-based VR for training faces a number of challenges including fast collision detection and real ...

Sequential epiretinal membrane removal with internal limiting membrane peeling in brilliant blue G-assisted macular surgery [PDF]

open access: yes, 2010
Purpose To assess the selectivity of brilliant blue G (BBG) staining by analysing the morphological components of unstained and stained tissue obtained during epiretinal membrane (ERM) removal with internal limiting membrane (ILM) peeling in BBG ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Robotic single-port plus one assist port splenectomy in an adult: a case report with video

open access: yesJournal of Minimally Invasive Surgery
Minimally invasive techniques are increasingly used in hepatobiliary and pancreatic surgeries, but robotic single-port (SP) splenectomy remains uncommon due to the rarity of splenic diseases.

Recurrent Ovarian Cancer with the Involvement of Urinary Organs: is There Place for Secondary Cytoreductive Surgery?

open access: yesGalician Medical Journal, 2017
The objective of the research was to estimate early and long-term results of secondary cytoreductive surgery performed for recurrent ovarian cancer with involvement of urinary organs. Materials and methods. The study included 62 patients with recurrent

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...
