8; P = .02), family history of TAA (OR = 7.6; P = .04), hypertension (OR = 1.7; P = .006), and obesity (OR = 1.7; P = .006). Diabetes, infrarenal AAA location, and smoking have a negative association.
Conclusions: TAAs are relatively common in patients with AAA. Routine or targeted screening with a chest CT at the time of AAA diagnosis may be indicated. (J Vasc Surg 2012;56:1261-5.)”
“Memory dysfunction in mild cognitive impairment (MCI) due to Alzheimer’s pathology is primarily associated with episodic memory deficits linked to deterioration of the medial temporal lobes (MTLs). click here Currently, there
is a call to discover novel biomarkers of MCI in order to improve research criteria. Functional activation differences in MCI during episodic memory-task performance are often evidenced in the MTLs, and frontal and parietal lobes, but it has been suggested that examination of working memory (WM) differences may be more useful in detecting MCI. In the current study, MCI
and control participants performed a complex WM span (CWMS) Selleck SC79 task while functional magnetic resonance imaging (fMRI) data were acquired. Results indicated hyper-activation of the lateral temporal lobes, MTLs, and frontal and parietal regions during encoding and maintenance, and hyper-activation of the lateral temporal, frontal, and parietal lobes during CWMS recall for the MCI participants. Medial and lateral temporal differences during encoding and maintenance are consistent with previous findings, but lateral temporal differences are often not elaborated upon. Hyper-activation of the lateral temporal lobes during WM encoding and maintenance, and also during recall, suggests that this region may provide valuable information regarding WM impairment in MCI and Alzheimer’s. Given that whole-brain functional imaging of the MTLs is often limited due to artifact and partial voluming of sub-fields, examination of lateral temporal differences may provide a novel biomarker related to WM impairment in
MCI. (C) 2013 Elsevier Ltd. All rights reserved.”
“Schizophrenia (SCZ) is a severe neuropsychiatric disorder with prominent genetic etiologic factors. The dopamine receptor DRD3 gene is a strong candidate in genetic studies of SCZ because Fossariinae of the dopamine hypothesis of SCZ and the selective expression of D(3) in areas of the limbic system implicated in the disease. We examined 15 single-nucleotide polymorphisms (SNPs) in DRD3 in our sample of European origin consisting of 95 small nuclear SCZ families and 167 case-control pairs. We also examined four BDNF SNPs in our samples because of evidence for BDNF regulation of DRD3 expression (Guillin et al., 2001). We found a nominally significant genotypic association with rs7633291 and allelic association with rs1025398 alleles. However, these observations did not survive correction for multiple testing.
