question:
Williams syndrome (WS), a genetic disorder resulting from hemizygous microdeletion of chromosome 7q11.23, has emerged as a model for identifying the genetic architecture of socioemotional behavior. Common polymorphisms in GTF2I, which is found within the WS microdeletion, have been associated with reduced social anxiety in the general population. Identifying neural phenotypes affected by these polymorphisms would help advance our understanding not only of this specific genetic association but also of the broader neurogenetic mechanisms of variability in socioemotional behavior.', 'Through an ongoing parent protocol, the Duke Neurogenetics Study, we measured threat-related amygdala reactivity to fearful and angry facial expressions using functional magnetic resonance imaging, assessed trait personality using the Revised NEO Personality Inventory, and imputed GTF2I rs13227433 from saliva-derived DNA using custom Illumina arrays. Participants included 808 non-Hispanic Caucasian, African American, and Asian university students.', 'The GTF2I rs13227433 AA genotype, previously associated with lower social anxiety, predicted decreased threat-related amygdala reactivity. An indirect effect of GTF2I genotype on the warmth facet of extraversion was mediated by decreased threat-related amygdala reactivity in women but not men.
answer:
Does a Common Polymorphism in a Williams Syndrome Gene predict Amygdala Reactivity and Extraversion in Healthy Adults?


question:
In patients presenting with a breast lesion, when initial core biopsy histology falls into the category of "uncertain malignant potential" (i.e. a B3 lesion), the next line of investigation has traditionally been a surgical biopsy (SBx). Vacuum-assisted biopsy (VAB) may be a viable minimally invasive alternative to SBx for B3 lesions. The primary aims of this study were to establish whether VAB reduces the need for surgical biopsy and determine VAB sensitivity for carcinoma following initial B3 histology.', 'B3 lesion data was collected from 2004 to 2013 retrospectively, from a single institution that utilises both VAB and SBx.', 'A total of 413 lesions were categorised B3 on initial biopsy. Mean age was 61 years (range: 24-91 years). Mean follow up was 52 months (range: 19-60 months). 156 patients (38%) underwent VAB. Only 20% of patients underwent VAB in 2004, with an increase to 95% by 2013. VAB histology revealed twelve carcinomas, all of which progressed to surgical excision. In six cases, a SBx was required following VAB in order to provide further diagnostic information. In one case, carcinoma was missed on VAB.
answer:
Is vacuum-assisted biopsy a viable alternative to surgical biopsy in the investigation of breast lesions of uncertain malignant potential?


question:
Hepatocellular carcinoma is one of the most common malignancies worldwide. The only curative treatment is surgery. As hepatocellular carcinoma is often associated with liver cirrhosis, patients are at risk for postoperative liver failure. In the recent years, platelets are thought to play an important role in liver regeneration.The aim of this study was to discover the relevance of postoperative platelet counts after liver resection for hepatocellular carcinoma.', 'Data of 68 patients who underwent liver resection for hepatocellular carcinoma between July 2007 and July 2012 in a single centre were analysed. Postoperative morbidity and mortality were evaluated in regard to postoperative platelet counts. Comparative analysis between patients with platelet counts ≤100 2x109/ l and >100 x109/ l at d1 was performed in regard to postoperative outcome.', 'Within this cohort, 43 patients (63%) suffered from histologically proven liver cirrhosis. Postoperative mortality was statistically significant associated with postoperative reduced platelet counts. Comparative analysis showed significantly elevated postoperative bilirubin levels and lower prothrombin time in patients with platelet counts ≤ 100 1x109/ l at d1.
answer:

Is low postoperative platelet count associated with negative outcome after liver resection for hepatocellular carcinoma?
