The Objective of this research was to study the relationship of angiotensin converting enzyme (ACE) genotype with serum triglycerides concentration in stroke patients. The insertion/deletion (I/D) ACE polymorphism was identified by using polymerase chain reaction in 122 prospectively studied ischemic stroke patients (age 45-91 years). Serum triglycerides concentration was determined at admission and 3 months after the stroke, and compared between the ACE genotype groups (37 D/D, 68 D/I, 17 I/I). All clinical characteristics were similar in the three groups. Patients with D/D genotype had mean serum triglycerides concentration significantly higher in acute (179.0+/-111.8 mg/dl) and chronic phase (176.4+/-121.6 mg/dl) than those with I/I genotype (acute phase: 108.7+/-36.1 mg/dl, P=0.019; chronic phase: 116.0+/-44.3 mg/dl, P=0.021). The results showed that serum triglycerides concentration is elevated in stroke patients with the DD ACE genotype and it may be related to the risk of cerebrovascular disease associated with this polymorphism.
Transient global amnesia (TGA), characterised by a profound anterograde amnesia, is a model of interest to study the acquisition of novel meanings independent of episodic functioning. Three patients were tested during a TGA attack, two in the early recovery phase and the third during the acute phase of TGA, with a semantic priming task involving a restructuring process of conceptual knowledge. During TGA, all patients demonstrated priming effects. Results obtained the day after the episode with the same task showed that these effects persisted at least one day. Episodic memory seems not to be critical for the formation of novel connections among unrelated semantic representations, in accordance with Tulving's model of memory, i.e. episodic memory is not necessary for the acquisition of semantic information.
