- A BCR/ABL-negative chronic myeloid leukemia (CML) with t(12;14) (p12;q11-13) as the sole chromosomal abnormality was investigated by fluorescence in situ hybridization (FISH), which disclosed a cryptic insertion of ETV6 (previously called TEL), located at 12p12, into ABL at chromosome band 9q34. ETV6/ABL fusion was confirmed by RT-PCR, revealing that the first five exons of ETV6 were fused in frame with ABL at exon 2. Wild-type ETV6 was expressed, in accordance with the FISH results showing no deletion of the second ETV6 allele. ETV6/ABL chimeric transcripts have previously been reported in acute leukemias, but never before in CML. The present case suggests that ETV6/ABL positivity may constitute a new genetic subgroup of BCR-negative CML.

- This study reports the results of torsion tests, pull-out tests, and lateral loading tests on osseointegrated commercially pure titanium fixtures. The tests were performed in vivo on six beagle dogs. Three fixtures, each with a diameter of 3.7 mm, were installed bilaterally in the tibia of each animal. The mean maximal pull-out load was 1.55 kN (n = 4), the mean maximal lateral transverse load was 0.21 kN (n = 2), the mean maximal lateral axial load was 0.18 kN (n = 2), the mean breakpoint torque was 0.31 Nm (n = 3), and the mean maximal torque was 0.43 Nm (n = 3). The torsion test revealed an almost immediate plastic deformation of the interface between the implant and bone; this indicates that although the contact between the bone and the implant is close, there is no strong bond, at least not in shear. The major transfer of load from the implant to the surrounding bone tissue must therefore depend on the design of the implant. A histological evaluation with measurements of the amount of bone in contact with the fixtures was performed. By the use of the histological and mechanical data, it is possible to estimate shear stresses in bone tissue (pull-out test) and in the interface (torque test). The mean maximal shear stress in bone tissue in the pull-out tests was 100 MPa (n = 4); the mean shear stress in the interface was 4.3 MPa (n = 3) in the torsion tests at the breakpoint torque and was 6.0 MPa (n = 3) at the maximal torque. It was also possible to estimate the shear modulus of elasticity in the pull-out and torque tests. The mean shear modulus in pull-out was 119 MPa (n = 4), and the mean apparent shear modulus in torsion was 9 kPa (n = 3) for an assumed interface thickness of 100 nm and was 86 kPa (n = 3) for an assumed interface thickness of 1,000 nm.

- The risk of distant recurrence in breast cancer patients is difficult to assess with current clinical and histopathological parameters, and no validated serum biomarkers currently exist. Using a recently developed recombinant antibody microarray platform containing 135 antibodies against 65 mainly immunoregulatory proteins, we screened 240 sera from 64 patients with primary breast cancer. This unique longitudinal sample material was collected from each patient between 0 and 36 mo after the primary operation. The velocity for each serum protein was determined by comparing the samples collected at the primary operation and then 3-6 mo later. A 21-protein signature was identified, using leave-one-out cross-validation together with a backward elimination strategy in a training cohort. This signature was tested and evaluated subsequently in an independent test cohort (prevalidation). The risk of developing distant recurrence after primary operation could be assessed for each patient, using her molecular portraits. The results from this prevalidation study showed that patients could be classified into high- versus low-risk groups for developing metastatic breast cancer with a receiver operating characteristic area under the curve of 0.85. This risk assessment was not dependent on the type of adjuvant therapy received by the patients. Even more importantly, we demonstrated that this protein signature provided an added value compared with conventional clinical parameters. Consequently, we present here a candidate serum biomarker signature able to classify patients with primary breast cancer according to their risk of developing distant recurrence, with an accuracy outperforming current procedures.

2,6-Dichlorophenyl methylsulphone induced behavioural impairments in rats and mice in relation to olfactory mucosal metaplasia

- 2,6-Dichlorophenyl methylsulphone (2,6-diClPh-MeSO2) induces persistent olfactory mucosal metaplasia and a strong glial fibrillary acidic protein increase in the olfactory bulb of mice. Furthermore, 2,6-diClPh-MeSO2 gives rise to a long-lasting hyperactivity along with an impaired radial arm maze performance. To study cause-effect relationships, olfactory mucosal histopathology, glial fibrillary acidic protein induction and neurobehavioural deficits were re-examined in mice and rats of both sexes given a single intraperitoneal dose of 2,6-diClPh-MeSO2 (16 and 65 mg/kg). There was a clear difference in the character of the olfactory mucosal lesions in the two species. In mice, an extensive metaplasia characterised by severe fibrosis, cartilage and bone formation accompanied with large polyps filling the nasal lumen was confirmed. In rats, a dose-dependent weak metaplasia with patchy loss of olfactory epithelium was observed three weeks after dosing, preferentially at the dorsal meatus, nasal septum, and the tips of the middle ethmoturbinates. Large areas of intact olfactory epithelium remained in all animals, particularly in the low dose rats. In both species, 2,6-diClPh-MeSO2 gave rise to significantly increased motor-activities, impaired performance in the radial arm maze, and glial fibrillary acidic protein-induction. Only rats showed hyperactivity at the low dose. Performance in the Morris water maze was unaffected in rats of both sexes indicating that a general impairment in spatial learning could not be supported. We propose that the observed hyperactivity and radial arm maze acquisition deficits originated from a direct effect of 2,6-diClPh-MeSO2 in the brain rather than being a consequence of the olfactory mucosal lesion.
