Precis: Our laboratory study determined the approximate suture diameter for use in intraluminal stenting of the Baerveldt glaucoma implant (BGI) to prevent postoperative hypotony. Commercial 3-0 monofilament nylon sutures which are commonly used may vary significantly outside of this diameter.

Purpose: Postoperative hypotony is a complication of surgical treatment of glaucoma using the BGI.

Article Synopsis
  • REM sleep behavior disorder (RBD) is linked to dream enactment behaviors and can precede conditions like Parkinson's disease and dementia, indicating potential early neurodegeneration.
  • A study comparing visual acuity among patients with RBD, idiopathic RBD (iRBD), and healthy controls found significant differences in contrast sensitivity visual acuity (CSVA) scores, with iRBD patients showing declines over time.
  • The results suggest that early visual processing issues in iRBD may mirror changes seen in Parkinson's disease, indicating possible dopaminergic neuron loss in the retina.

Unlike mammalian cells, Drosophila melanogaster contains only a single member of the diphosphoinositol polyphosphate phosphohydrolase subfamily of the Nudix hydrolases, suggesting that functional specialisation has not occurred in this organism. In order to evaluate its function, Aps was cloned and characterized. It hydrolyses a range of (di)nucleoside polyphosphates, the most efficient being guanosine 5'-tetraphosphate (K(m)=11 microM, k(cat)=0.

Unimolecular half-adders based upon an arylvinyl-bipyridyl fluorophore platform were demonstrated where all the chemical input combinations were fully processed by half-adder molecules to generate the arithmetic results of the entire truth table.
