question:
Testicular germ cell tumours are the most common malignancies in young males. Molecular biology studies of these tumours are often contradictory. Two histological groups, seminoma and non-seminoma, differ both morphologically and in malignant behaviour. Although a common cytogenetic feature is seen, namely the amplification of the 12p chromosomal region, the development mechanisms of less aggressive seminomas and more aggressive non-seminomas are unknown.', 'Occurrence of structural genetic alterations was analyzed in 18 seminomas and 22 non-seminomas for genes involved in the malignant tumour phenotype: cadherin 1, Type 1, E-cadherin (Epithelial), CDH1; adenomatous polyposis coli, APC; NME/NM23 nucleoside diphosphate kinase 1, NME1; tumour protein P53, TP53; cyclin-dependent kinase inhibitor 2A, CDKN2A; retinoblastoma 1, RB1; RAD51 recombinase, RAD51; mutS homolog 2, MSH2; MutL homolog 1, MLH1; breast cancer 1, early onset, BRCA1; BCL2-Associated X Protein, BAX; ATP-Binding Cassette, Sub-Family G (WHITE), Member 2, ABCG2. Genetic alterations, loss of heterozygosity and microsatellite instability, were analyzed using restriction fragment or microsatellite repeat length polymorphisms.', 'A difference in genetic alteration occurrence between seminomas and non-seminomas was observed.
answer:
Do histological groups of human postpubertal testicular germ cell tumours harbour different genetic alterations?

question:
Circulating adiponectins have multiple protective roles as anti-diabetic, anti-atherosclerotic, and anti-inflammatory factors. We examined the relationship between plasma adiponectin concentration and other cardiovascular risk in nondiabetic coronary artery disease (CAD) men and the relationship can be maintained even after adjusted for major environmental factors that contribute to adiponectin concentrations.', 'Nondiabetic CAD men (n=613) were 31-70 y and had body mass index (BMI) of 18.5-29.9 kg/m2.', "Circulating adiponectins positively correlated with age and negatively with BMI, waist circumference and % body fat (p-values of all <0.001). Plasma adiponectin concentrations were higher in never-smokers (5.07+/-0.30 microg/ml) than current (4.15+/-0.12 microg/ml) and ex-smokers (3.75+/-0.20 microg/ml) both before and after adjusted for age and adiposity (p=0.002 and p=0.008, respectively), however they were not significantly different according to alcohol drinking status. After adjusted for age, adiposity and cigarette smoking, plasma adiponectin still have positive correlations with HDL cholesterol, apolipoprotein AI and LDL particle size, and inversely with fasting triglyceride, atherogenic index, insulin resistance and C-reactive protein (CRP). However there was no significant relationships between adiponectin and apolipoprotein B, total cholesterol or LDL cholesterol. In subset analysis by tertile adiponectin concentrations (lowest: <2.92, moderate: 2.92<or=adiponectin<4.75, highest: >or=4.75 microg/ml), 'moderate' and 'highest' adiponectin groups had lower triglyceride (p<0.001), lower atherogenic index (p=0.001), lower fasting insulin (p=0.004), lower insulin resistance (p=0.001), lower CRP (p=0.001), higher HDL cholesterol (p<0.001), higher apolipoprotein AI (p=0.005) and higher LDL particle size (p<0.001) as compared with 'lowest' adiponectin group when adjusted for age, adiposity and cigarette smoking. Platelets were lower in 'highest' adiponectin groups as compared with 'lowest' and 'moderate' adiponectin group after the adjustment. However, there was no significant difference in total cholesterol (p=0.145), LDL cholesterol (p=0.145), apolipoprotein B (p=0.222) and fasting glucose (p=0.157).
answer:
Is plasma adiponectin related to other cardiovascular risk factors in nondiabetic Korean men with CAD , independent of adiposity and cigarette smoking : cross-sectional analysis?

question:
Aiming to identify macrolide and beta-lactam resistance in clinical bacterial isolates rapidly and accurately, a two-step algorithm was developed based on detection of eight antibiotic resistance genes.', 'Targeting at genes linked to bacterial macrolide (msrA, ermA, ermB, and ermC) and beta-lactam (blaTEM, blaSHV, blaCTX-M-1, blaCTX-M-9) antibiotic resistances, this method includes a multiplex real-time PCR, a melting temperature profile analysis as well as a liquid bead microarray assay. Liquid bead microarray assay is applied only when indistinguishable Tm profile is observed.', 'The clinical validity of this method was assessed on clinical bacterial isolates. Among the total 580 isolates that were determined by our diagnostic method, 75% of them were identified by the multiplex real-time PCR with melting temperature analysis alone, while the remaining 25% required both multiplex real-time PCR with melting temperature analysis and liquid bead microarray assay for identification. Compared with the traditional phenotypic antibiotic susceptibility test, an overall agreement of 81.2% (kappa=0.614, 95% CI=0.550-0.679) was observed, with a sensitivity and specificity of 87.7% and 73% respectively. Besides, the average test turnaround time is 3.9h, which is much shorter in comparison with more than 24h for the traditional phenotypic tests.
answer:
Does a rapid two-step algorithm detect and identifies clinical macrolide and beta-lactam antibiotic resistance in clinical bacterial isolates?
