Context: High sensitivity C-reactive protein (hsCRP) is more sensitive than standard C-reactive protein (CRP) assay in evaluating the risk of coronary heart disease and other atherosclerotic events. By this time, there are several reports that type 2 diabetic subjects have higher serum levels of hsCRP than those of non-diabetic subjects. However, there are few reports about factors which have influence upon the level of serum hsCRP in type 2 diabetic subjects. We had evaluated the association of serum hsCRP level with risk factors of cardiovascular diseases and carotid intima-media thickness (IMT) in type 2 diabetic subjects.', 'One hundred and five patients (59 men and 46 women) with type 2 diabetes were recruited. Subjects with severe cardiovascular diseases were excluded. All subjects were undergone carotid ultrasonography for evaluation of carotid IMT. Serum hsCRP concentrations were measured.', 'Serum hsCRP level was correlated with mean left IMT (r = 0.366, P = 0.003), maximal left IMT (r = 0.370, P = 0.002), mean right IMT (r = 0.281, P = 0.023) and maximal right IMT (r = 0.370, P = 0.002), body mass index (r = 0.377, P < 0.001), waist circumference (r = 0.342, P < 0.001), waist-hip ratio (r = 0.229, P = 0.020), serum total cholesterol (r = 0.202, P = 0.024), serum triglyceride (r = 0.292, P = 0.022) and serum low-density lipoprotein (r = 0.133, P = 0.044).
Answer: Our result shows that serum hsCRP level is correlated with carotid IMT and the risk factors of cardiovascular diseases and may be useful to predict accelerated atherosclerotic process in type 2 diabetic subjects.

Context: With the advent of new and more efficient anti-androgen drugs targeting androgen receptor (AR) in breast cancer (BC) is becoming an increasingly important area of investigation. This would potentially be most useful in triple negative BC (TNBC), where better therapies are still needed. The assessment of AR status is generally performed on the primary tumor even if the tumor has already metastasized. Very little is known regarding discrepancies of AR status during tumor progression. To determine the prevalence of AR positivity, with emphasis on TNBCs, and to investigate AR status during tumor progression, we evaluated a large series of primary BCs and matching metastases and recurrences.', 'AR status was performed on 356 primary BCs, 135 matching metastases, and 12 recurrences using a next-generation Tissue Microarray (ngTMA). A commercially available AR antibody was used to determine AR-status by immunohistochemistry. AR positivity was defined as any nuclear staining in tumor cells ≥1 %. AR expression was correlated with pathological tumor features of the primary tumor. Additionally, the concordance rate of AR expression between the different tumor sites was determined.', 'AR status was positive in: 87 % (307/353) of primary tumors, 86.1 % (105/122) of metastases, and in 66.7 % (8/12) of recurrences. TNBC tested positive in 11.4 %, (4/35) of BCs. A discrepant result was seen in 4.3 % (5/117) of primary BC and matching lymph node (LN) metastases. Three AR negative primary BCs were positive in the matching LN metastasis, representing 17.6 % of all negative BCs with lymph node metastases (3/17). Two AR positive primary BCs were negative in the matching LN metastasis, representing 2.0 % of all AR positive BCs with LN metastases (2/100). No discrepancies were seen between primary BC and distant metastases or recurrence (n\u2009=\u200917).
Answer: Most primary (87 %) and metastasized (86.1 %) BCs are AR positive including a significant fraction of TNBCs (11.4 %). Further, AR status is highly conserved during tumor progression and a change only occurs in a small fraction (4.1 %). Our study supports the notion that targeting AR could be effective for many BC patients and that re-testing of AR status in formerly negative or mixed type BC's is recommended.

Context: Genomic selection (GS) is a promising approach for decreasing breeding cycle length in forest trees. Assessment of progeny performance and of the prediction accuracy of GS models over generations is therefore a key issue.', 'A reference population of maritime pine (Pinus pinaster) with an estimated effective inbreeding population size (status number) of 25 was first selected with simulated data. This reference population (n\u2009=\u2009818) covered three generations (G0, G1 and G2) and was genotyped with 4436 single-nucleotide polymorphism (SNP) markers. We evaluated the effects on prediction accuracy of both the relatedness between the calibration and validation sets and validation on the basis of progeny performance. Pedigree-based (best linear unbiased prediction, ABLUP) and marker-based (genomic BLUP and Bayesian LASSO) models were used to predict breeding values for three different traits: circumference, height and stem straightness. On average, the ABLUP model outperformed genomic prediction models, with a maximum difference in prediction accuracies of 0.12, depending on the trait and the validation method. A mean difference in prediction accuracy of 0.17 was found between validation methods differing in terms of relatedness. Including the progenitors in the calibration set reduced this difference in prediction accuracy to 0.03. When only genotypes from the G0 and G1 generations were used in the calibration set and genotypes from G2 were used in the validation set (progeny validation), prediction accuracies ranged from 0.70 to 0.85.
Answer: This study suggests that the training of prediction models on parental populations can predict the genetic merit of the progeny with high accuracy: an encouraging result for the implementation of GS in the maritime pine breeding program.
