RESUMEN
In previous surveys for the investigation of Bursaphelenchus xylophilus in Turkey, several Bursaphelenchus species, except B. xylophilus, were detected. To determine the insect vectors of these previously reported Bursaphelenchus species, trap trees of each pine species (Pinus brutia and P. nigra) were cut and kept in the field from April to September in 2011. Aphelenchoides stammeri was isolated from wood chip samples of P. nigra from Isparta (Sütçüler). A. stammeri was first identified by using morphological features and allometric criteria of females and males. In addition, molecular analysis using sequences of 18S and 28S ribosomal (rRNA) genes of A. stammeri was performed. This is the first report of A. stammeri from Turkey.In previous surveys for the investigation of Bursaphelenchus xylophilus in Turkey, several Bursaphelenchus species, except B. xylophilus, were detected.

RESUMEN
The purpose of the present study was to investigate the presence of an elongated transverse aortic arch (ETA), which has been reported to be specific for Turner syndrome, in a population without Turner syndrome. A set of 1,012 patients (713 men, 299 women) under 40 years old, who underwent thoracic CT examination in our radiology department between July 2016 and December 2016, were included in the study. CT scans were performed by 16-slice scanners. CT images were retrieved from the picture archiving and communication system and retrospectively re-assessed by two radiologists. Diagnostic criteria for ETA, which are late take-off of the left subclavian artery (LSA), convex kinking of the inferior aortic arch along the lesser curvature and flattening of the transverse aortic arch, were searched in each case. The mean age of the study population was 25.5 ± 10.0 years. Late take-off of the LSA was detected in 17 (1.7%) subjects (10 men, 7 women). In six of these, the other criteria for ETA were not met. However, in the other 11 (1.1% of the study population) cases, in addition to late take-off of the LSA, aortic morphology was compatible with ETA. The dimensions of the aortic root and the ascending and descending aorta were within normal limits in all 17 cases. Our results supported the presence of ETA in subjects without Turner syndrome with â¼1.1% frequency. This is the first preliminary report regarding the frequency of ETA in non-Turner subjects. Clin.
