Inclusion of People Poststroke in Cardiac Rehabilitation Programs in Canada: A Missed Opportunity for Referral.

Background: Evidence supports establishing a continuum of care from stroke rehabilitation (SR) to cardiac rehabilitation programs (CRPs). It is not known to what extent people poststroke are being integrated. This study aimed to determine the proportion of CRPs that accept referrals poststroke, barriers/facilitators, and eligibility criteria.

Historical article: Titration studies and the structure of DNA.

During the period of 1946-1956 ideas on the structure of the nucleic acids, especially DNA, were profoundly influenced by physico-chemical studies and, in particular, by electrometric titration studies pioneered by J. Masson Gulland and D.O.

Factors modifying vitreous pressure in cataract surgery.

A prospective study of 267 intracapsular cataract extractions was conducted to assesses what makes an eye soft and capable of safely receiving an intraocular lens implant. The study showed that the use of glycerol, given orally before the operation, plus retrobulbar anesthesia is the most effective way of reducing the vitreous pressure, that there is a direct relation between this reduction and age, and that there is no apparent correlation between the preoperative intraocular pressure and the vitreous pressure.

The denaturation-renaturation of chicken-muscle triosephosphate isomerase in guanidinium chloride.

1. The process of denaturation of the chicken muscle dimeric enzyme triosephosphate isomerase on addition of guanidinium chloride has been studied at pH 7.6, the pH at which the recovery of activity is optimal (100%) on removal of denaturant.
