Only three of the structural imaging studies found differences between users and controls.
Conclusions. Functional neuroimaging studies suggest a modulation of global and prefrontal metabolism both during the resting state and after the administration of THC/marijuana cigarettes. Minimal Idasanutlin evidence of major effects of cannabis on brain structure has been reported.”
“BACKGROUND: Dissection of the superficial temporal artery (STA) is often required in preparation for a bypass procedure. Traditionally, dissection
of the STA involves a direct cutdown on the artery after marking the course of the artery on the skin with the help of a Doppler ultrasound probe.
OBJECTIVE: We describe a method that takes advantage of the position of the STA superficial to the temporal fascia.
METHODS: The technique was used in a total of 38 procedures in 32 patients to create synangiosis or extracranial-intracranial STA bypasses. The STA was dissected using a blunt malleable brain retractor that was inserted into the subgaleal plane
directly over the STA, allowing creation of a linear incision and concurrent protection of the STA in its bed. Either computed tomography- or catheter-based angiography was used to evaluate the patency postoperatively.
RESULTS: All STA vessels were dissected without complications or injury to the graft vessel. The sole complication was a superficial wound breakdown in a synangiosis case. LY2228820 price Postoperative angiography demonstrated patency in all but 1 of the 24 bypass cases (95.8%).
CONCLUSION: We describe a method that takes advantage of the position of the STA superficial to the temporal fascia to allow rapid, safe, and efficacious dissection. The incision is linear and easier to manage and close. In our series, there were no technical complications Chlormezanone related to the dissection of the STA.”
“Background. The psychosocial vulnerability model of hostility posits that hostile individuals, given their oppositional attitudes and behaviours, are more likely to have increased interpersonal conflicts, lower social support, more stressful life events (SL-E) and higher likelihood of depression. However, little research has
tested this hypothesis using large-scale prospective samples. The present study aims to assess the predictive value of hostility for depressive mood.
Method. Data are from 3399 participants in the Whitehall 11 cohort study, aged 35-55 years at baseline (phase 1 1985-1988). Cynical hostility was measured at phase 1. Depressive mood was assessed at phase 7 (2002-2004). Sociodemographic characteristics, health-related behaviours, common mental disorders and antidepressant medication intake were assessed at phase 1. SL-E and confiding/emotional support were measured at phases 1, 2 (1989-1990) and 5 (1997-1999).
Results. Compared with participants in the lowest quartile of cynical hostility, those in the highest quartiles were more likely to have depressive mood [second quartile: odds ratio (OR) 1.58, 95% confidence interval (Cl) 1.
