Mechanistic insights for the photoredox organocatalytic fluorination of aliphatic carbons by anthraquinone using time-resolved and DFT studies

Nanosecond TAS and DFT calculations reveal mechanistic insights for photoredox fluorination of aliphatic C–H bonds and evidence of an anthraquinone–Selectfluor® exciplex.

Pseudohypoparathyroidism associated with cri du chat syndrome

A case is reported in which features of pseudohypoparathyroidism were found in association with the cri du chat syndrome. This association may throw some light on the localization of the chromosomal abberration which underlies pseudohypoparathyroidism, since deletion of the short arm of chromosome 5 has been clearly established in the cri du chat syndrome.

Thyrotoxic pretibial myxoedema in Asian patients in Singapore

Over a 5-year period, three cases of thyrotoxic pretibial myxoedema were encountered. The incidence of pretibial myxoedema in Chinese thyrotoxic patients in Singapore was 0·7% (0·3% in females and 1·6% in males). One of the three patients also had thyroid acropachy. The incidence of thyrotoxic pretibial myxoedema in Singapore is compared with that in the literature and the aetiology briefly reviewed.
