Abstract
Third-harmonic generation of high-intensity, sub-100-fs idler pulses from a Ti:sapphire-laser-pumped optical parametric amplifier is demonstrated by using a single nonlinear crystal of BiB₃O₆ (BIBO). Maximum internal energy conversion as high as 11% from the fundamental to the third harmonic is achieved by phase- and group-velocity matching for the direct cubic nonlinear process together with the velocity-mismatched cascading quadratic processes.

Abstract
The aim of this study was to determine the pathological complete remission (pCR) rate, and its relationship to clinical outcome, in patients with adenocarcinoma of the stomach or oesophagogastric junction receiving preoperative 5-fluorouracil, leucovorin, oxaliplatin and docetaxel (FLOT) every 2 weeks. Data from these patients who received at least one cycle of preoperative FLOT followed by surgery were prospectively collected in three German centres. Outcome analyses were conducted and tumour samples were evaluated for pathological remission by a central pathologist. A total of 46 patients were included in this analysis. All patients had clinical T3- and/or N+-stages and 11 (23.9%) had distant metastases (M1). After a median of 4 (range 2-8) preoperative cycles, 8 of 46 patients (17.4%) achieved a pCR. The pCR rate was highest in tumours of intestinal type histology (30.8%) and in those located in the oesophagogastric junction (30.4%) and lowest in patients with diffuse/mixed type tumours (0%) or tumours located in the stomach (4.3%; p < 0.05 for both comparisons). Patients with pCR had 100% probability of overall and disease-free survival (DFS) during the observation period, which was significantly higher (p = 0.037 and p = 0.009, respectively) than the survival probability in patients without pCR. In conclusion, treatment intensification using FLOT was associated with significant pCR rates in patients with oesophagogastric cancer. The distribution of pCR appeared to be significantly different according to histological type and location of the tumours.

Abstract
BACKGROUND The current study was performed to investigate the potential impact of tumor cell expression of estrogen receptor-α (ER-α), progesterone receptor (PR), and androgen receptor (AR) on the outcomes of patients who received radiotherapy (RT) for non-small cell lung cancer (NSCLC). METHODS Tumor cell expression of ER-α, PR, and AR as well as 9 additional potential prognostic factors were retrospectively evaluated in 64 patients who underwent RT for AJCC stage II/III NSCLC. The endpoints investigated were locoregional control, metastases-free survival, and overall survival. The additional potential prognostic factors were age, gender, Karnofsky performance score, histology, T classification, N classification, surgery, smoking during RT, and hemoglobin levels during RT. Subgroup analyses were performed for women and men. RESULTS On univariate analysis, locoregional control was not found to be associated with expression of PR or AR. ER-α expression demonstrated a strong trend toward worse locoregional control. On multivariate analysis, ER-α expression was found to be significantly associated with worse locoregional control (risk ratio [RR], 3.12; P = .035). On univariate analysis, metastases-free survival was not associated with expression of ER-α, PR, or AR. On univariate analysis, survival was found to be negatively associated with expression of ER-α (P = .003) but not with PR or AR expression. On multivariate analysis, ER-α expression maintained significance (RR, 2.73; P = .022). CONCLUSIONS Tumor cell expression of ER-α was found to be a negative prognostic factor for treatment outcomes in both women and men. Expression of PR and AR was not associated with outcomes.

Abstract
AIMS Micro RNAs (miRNAs) are small, single-strand RNAs, playing an important role in post-transcriptional gene regulation. The placenta is considered to play a key role in pathogenesis of preeclampsia. The purpose of this study was to demonstrate deregulation of miRNAs in placentas with preeclampsia using formalin-fixed and paraffin-embedded (FFPE) tissues. METHODS Expression levels of 162 miRNAs were measured in FFPE placental tissues (5 with severe preeclampsia, 5 from a control group) using a quantitative qPCR based technique. RESULTS Six miRNAs were more than 2-fold over-expressed in severe preeclampsia: let-7b, miRNA-302*, miRNA-104, miRNA-128a, miRNA-182* and miRNA-133b. Gene ontology analyses were performed using the algorithms "TargetScanS", "microRNA", and "PicTar". CONCLUSIONS Two of the up-regulated miRNAs (miRNA-182* and miRNA-133b) are putative regulators of the transcript variants 1 and 2 of the BCL2-like gene, which controls apoptosis. miRNA-182* is also a probable angiogenesis regulator via angiogenin and VEGF-B. Apoptosis and angiogenesis are major mechanisms presumed to be involved in the pathogenesis of preeclampsia. Moreover, usability of qPCR technique based miRNA profiling for FFPE tissues was proofed. Hence FFPE tissue is the most widely used material for retrospective clinical studies, this method has a great property for future investigations in placenta research.

Abstract
Generation of sub-50fs vacuum UV pulses with more than 2.5μJ energy at a 1kHz repetition rate is reported. The pulses at 160nm are produced using noncollinear difference-frequency four-wave mixing between the fundamental and third harmonics of an amplified Ti:sapphire laser in argon. While the pulse duration is maintained by increasing the phase-matching pressure, noncollinear interaction improves the conversion efficiency by 1 order of magnitude in comparison with the previous results in collinear geometry.

Abstract
PURPOSE The prognostic value of the tumor cell expression of the fibroblast growth factor 2 (FGF-2) in patients with non-small-cell lung cancer (NSCLC) is unclear. The present study investigated the effect of tumor cell expression of FGF-2 on the outcome of 60 patients irradiated for Stage II-III NSCLC. METHODS AND MATERIALS The effect of FGF-2 expression and 13 additional factors on locoregional control (LRC), metastasis-free survival (MFS), and overall survival (OS) were retrospectively evaluated. These additional factors included age, gender, Karnofsky performance status, histologic type, histologic grade, T and N category, American Joint Committee on Cancer stage, surgery, chemotherapy, pack-years, smoking during radiotherapy, and hemoglobin during radiotherapy. Locoregional failure was identified by endoscopy or computed tomography. Univariate analyses were performed with the Kaplan-Meier method and the Wilcoxon test and multivariate analyses with the Cox proportional hazard model. RESULTS On univariate analysis, improved LRC was associated with surgery (p = .017), greater hemoglobin levels (p = .036), and FGF-2 negativity (p <.001). On multivariate analysis of LRC, surgery (relative risk [RR], 2.44; p = .037), and FGF-2 expression (RR, 5.06; p <.001) maintained significance. On univariate analysis, improved MFS was associated with squamous cell carcinoma (p = .020), greater hemoglobin levels (p = .007), and FGF-2 negativity (p = .001). On multivariate analysis of MFS, the hemoglobin levels (RR, 2.65; p = .019) and FGF-2 expression (RR, 3.05; p = .004) were significant. On univariate analysis, improved OS was associated with a lower N category (p = .048), greater hemoglobin levels (p <.001), and FGF-2 negativity (p <.001). On multivariate analysis of OS, greater hemoglobin levels (RR, 4.62; p = .002) and FGF-2 expression (RR, 3.25; p = .002) maintained significance. CONCLUSIONS Tumor cell expression of FGF-2 appeared to be an independent negative predictor of LRC, MFS, and OS.

Abstract
BACKGROUND AND PURPOSE The addition of systemic drugs to whole-brain irradiation has not improved the survival of patients with multiple brain metastases, most likely because the agents did not readily cross the blood-brain barrier (BBB). Radiolabeling of cetuximab was performed to investigate whether this antibody crosses the BBB. CASE REPORT A patient with multiple brain lesions from non-small cell lung cancer was investigated. The largest metastasis (40 x 33 x 27 mm) was selected the reference lesion. On day 1, 200 mg/m(2) cetuximab (0.25% hot and 99.75% cold antibody) were given. On day 3, 200 mg/m(2) cetuximab (cold antibody) were given. Weekly doses of 250 mg/m(2) cetuximab were administered for 3 months. RESULTS The reference lesion showed enhancement of radiolabeled cetuximab ((123)I-Erbi) on scintigraphy; (123)I-Erbi crossed the BBB and accumulated in the lesion. The reference lesion measured 31 x 22 x 21 mm at 4 months. Enhancement of contrast medium was less pronounced. CONCLUSION This is the first demonstration of cetuximab crossing the BBB and accumulating in brain metastasis.

Abstract
We report on the generation of femtosecond pulses at 160 nm with energies up to 240 nJ at 1 kHz repetition rate and sub-50-fs pulse duration. This pulse energy is a 1-order-of-magnitude improvement compared with previous sub-100-fs sources in this wavelength range. The pulses are generated by four-wave difference-frequency mixing process between the fundamental of a Ti:sapphire laser and its third harmonic in argon. Pulse duration measurements are achieved by pump-probe ionization of Xe gas providing the cross correlation between the fifth harmonic and the fundamental.

Abstract
Supercontinuum generation in a water-filled photonic crystal fiber is reported. By only filling the central hollow core of this fiber with water, the fiber properties are changed such that the air cladding provides broadband guiding. Using a pump wavelength of 1200 nm and few-microjoule pump pulses, the generation of supercontinua with two-octave spectral coverage from 410 to 1640 nm is experimentally demonstrated. Numerical simulations confirm these results, revealing a transition from a soliton-induced mechanism to self-phase modulation dominated spectral broadening with increasing pump power. Compared to supercontinua generated in glass core photonic fibers, the liquid core supercontinua show a higher degree of coherence, and the larger mode field area and the higher damage threshold of the water core enable significantly higher pulse energies of the white light pulses, ranging up to 0.39microJ.

Abstract
A histopathologically confirmed biopsy is the gold standard for the diagnosis of vasculitis. Possible etiologies include primary systemic vasculitis, secondary vasculitis or isolated single organ vasculitis, although on histopathological grounds alone a clear differentiation is frequently not possible. The key criteria of morphological vasculitis work-up include vessel size, type of inflammation (granulomatous, necrotizing and/or leukocytoclastic) as well as the presence or absence of immune complexes and extravascular inflammatory changes. Together with the typical organ involvement and serological data, these criteria constitute the basis of vasculitis classification. Differential diagnostic overlaps and possible discrimination methods are presented. In the same way that the clinical approach of vasculitis patients is an interdisciplinary one, histopathology can only provide a definite diagnosis in combination with clinical and serological data. A conclusive morphological diagnosis depends on the right time of biopsy and the selection of appropriate biopsy material.

Abstract
Mastocytosis comprises a heterogeneous group of disorders characterized by proliferation and accumulation of mast cells in 1 or more organ systems. Mast cell leukemia (MCL) is an extremely rare subtype of mastocytosis in which a leukemic spread of mast cells and a rapid progression of disease is seen. In typical cases, mast cells are found in the peripheral blood. However, an aleukemic variant of MCL (formerly termed malignant mastocytosis) has also been described. We here report a case of aleukemic MCL with abnormal immunophenotype of mast cells and the classical c-kit point mutation Asp-816-Val (=D816V). The 75-year-old male patient had a short history of weight loss and lymphadenopathy. There were no urticaria pigmentosa-like skin lesions. The bone marrow was diffusely infiltrated with atypical mast cells that comprised more than 80% of all nucleated cells on a bone marrow smears. As assessed by immunohistochemistry, neoplastic mast cells expressed tryptase, chymase, CD2, CD25, CD68, and the KIT protein (CD117). Mutation analysis revealed the c-kit mutation D816V. Since circulating mast cells could not be detected in the peripheral blood, the diagnosis of aleukemic MCL was established in accordance to the updated WHO consensus classification. This case further supports the notion that the pathogenesis (c-kit mutation D816V) in MCL is closely related to that found in indolent mast cell disorders. However, additional (but yet unknown) molecular (genetic) defects have to be considered to explain the extremely heterogenous clinical course in these patients.

Abstract
PURPOSE To report the course and outcome of a group of fetuses with prenatal suspicion of coarctation of the aorta. MATERIALS AND METHODS Retrospective observational study in two tertiary fetal cardiology centers between 1993 - 2005. RESULTS 96 fetuses of whom 52 infants were born alive were studied. Of the 52 liveborn infants, 34 had coarctation of the aorta (65.4 %), thirteen had prenatally diagnosed additional cardiac anomalies (VSD, ASD, aortic and pulmonary stenosis, persistent left superior vena cava) and three were managed as having hypoplastic left heart syndrome. Three neonates had additional extracardiac malformations diagnosed prenatally. 22 neonates underwent surgery, nineteen within the first ten days of life. One neonate only developed clinical signs of coarctation on the fourteenth day of life. The early surgical mortality was three of 22 (13.6 %). The mortality was influenced by prematurity. The survival rate on the basis of intention-to-treat was twenty-nine of 34 neonates with confirmed coarctation (85.3 %). CONCLUSION Coarctation of aorta during fetal life continues to be a difficult diagnosis. The potential of progressive hypoplasia of left heart structures during gestation in the case of fetal aortic isthmus stenosis with the development of a hypoplastic left heart should be kept in mind and therefore sequential echo-cardiography is recommended during gestation.
