Abstract
Hyperthermia is a form of a cancer treatment which is frequently applied in combination with radiotherapy (RT) to improve therapy responses and radiosensitivity. The mode of action of hyperthermia is multifactorial; the one hand by altering the amount of the blood circulation in the treated tissue, on the other hand by modulating molecular pathways involved in cell survival processes and immunogenic interactions. One of the most dominant proteins induced by hyperthermia is the major stress-inducible heat shock protein 70 (Hsp70). Hsp70 can be found in the blood either as a free-protein (free HSP70) derived from necrotic cells, or lipid-bound (liposomal Hsp70) when it is actively released in extracellular vesicles (EVs) by living cells. The aim of the study was to evaluate the levels of free and liposomal Hsp70 before and after treatment with RT alone or hyperthermia combined with radiotherapy (HTRT) in dogs and cats to evaluate therapy responses. Peripheral blood was collected from feline and canine patients before and at 2, 4, 6 and 24 h after treatment with RT or HTRT. Hsp70 enzyme-linked immunosorbent assays (ELISAs) were performed to determine the free and liposomal Hsp70 concentrations in the serum. The levels were analysed after the first fraction of radiation to study immediate effects and after all applied fractions to study cumulative effects. The levels of free and liposomal Hsp70 levels in the circulation were not affected by the first singular treatment and cumulative effects of RT in cats however, after finalizing all treatment cycles with HTRT free and liposomal Hsp70 levels significantly increased. In dogs, HTRT, but not treatment with RT alone, significantly affected liposomal Hsp70 levels during the first fraction. Free Hsp70 levels were significantly increased after RT, but not HTRT, during the first fraction in dogs. In dogs, on the other hand, RT alone resulted in a significant increase in liposomal Hsp70, but HTRT did not significantly affect the liposomal Hsp70 when cumulative effects were analysed. Free Hsp70 was significantly induced in dogs after both, RT and HTRT when cumulative effects were analysed. RT and HTRT treatments differentially affect the levels of free and liposomal Hsp70 in dogs and cats. Both forms of Hsp70 could potentially be further investigated as potential liquid biopsy markers to study responses to RT and HTRT treatment in companion animals.

Abstract
PURPOSE Targeted radiation therapy has seen an increased interest in the past decade. In vitro and in vivo experiments showed enhanced radiation doses due to gold nanoparticles (GNPs) to tumors in mice and demonstrated a high potential for clinical application. However, finding a functionalized molecular formulation for actively targeting GNPs in tumor cells is challenging. Furthermore, the enhanced energy deposition by secondary electrons around GNPs, particularly by short-ranged Auger electrons is difficult to measure. Computational models, such as Monte Carlo (MC) radiation transport codes, have been used to estimate the physical quantities and effects of GNPs. However, as these codes differ from one to another, the reliability of physical and dosimetric quantities needs to be established at cellular and molecular levels, so that the subsequent biological effects can be assessed quantitatively. METHODS In this work, irradiation of single GNPs of 50 nm and 100 nm diameter by X-ray spectra generated by 50 and 100 peak kilovoltages was simulated for a defined geometry setup, by applying multiple MC codes in the EURADOS framework. RESULTS The mean dose enhancement ratio of the first 10 nm-thick water shell around a 100 nm GNP ranges from 400 for 100 kVp X-rays to 600 for 50 kVp X-rays with large uncertainty factors up to 2.3. CONCLUSIONS It is concluded that the absolute dose enhancement effects have large uncertainties and need an inter-code intercomparison for a high quality assurance; relative properties may be a better measure until more experimental data is available to constrain the models.

Abstract
Abstract
BACKGROUND
Magnetic drug targeting by employing external magnetic fields represents a promising approach for treatment of glioblastoma. To increase the anti-tumor therapeutic effect magnetic nanocarriers could be functionalized with tumor-targeting bioligands such as granzyme B (GrB). The serine protease GrB that is produced as an effector molecule by activated NK and T cells can induce specific tumor cell apoptosis.
MATERIAL AND METHODS
The targeting potential of the dextran-coated superparamagnetic iron oxide nanoparticles conjugated with GrB (GrB-SPIONs) was assessed in glioblastoma cells (U87, C6, GL261) by flow cytometry, confocal and electron microscopies. Magnetic field strength (320 mT) in the models of U87 glioblastoma in NMRI nu/nu mice and C6 glioma in Wistar rats was achieved by employing NdFeB cylindrical ferromagnet. The irradiation of the implanted tumors was performed using the CT-image guided Small Animal Radiation Research Platform (SARRP). Accumulation of the nanoparticles was assessed in paraffine-embedded specimens employing Prussian blues staining. Sections were additionally analyzed by IHC for apoptosis (caspase 3).
RESULTS
Synthesized GrB-SPIONs incorporated into the cytoplasm of tumor cells via the endolysosomal pathway and induced apoptosis in a dose-dependent manner. Intravenous injection of GrB-SPIONs resulted in the glioma-specific retention of the nanoparticles as was shown by high-field (11 T) magnetic resonance imaging and biodistribution studies (NLR-M2 measurements). Magnetic targeting of the nanoparticles in vivo drastically enhanced the accumulation of nanoparticles to the location of the magnet. Thus the local retention of nanoparticles was 12.3-fold higher as compared to application of GrB-SPIONs without external magnetic field. The presence of granzyme B on SPIONs has been shown to promote tumor cells death (IHC staining for caspase 3) and significantly increased overall survival. A combination of nanoparticle treatment with a single radiation dose (10 Gy) significantly prolonged the survival of rats as compared to animals treated only with magnetic targeting of GrB-SPIONs or radiotherapy alone (P<0.001).
CONCLUSION
Single-agent therapy with GrB-SPIONs demonstrated an impressive increase in overall survival of tumor-bearing animals. Combinatorial regimen employing magnetic targeting and stereotactic radiotherapy further enhanced the therapeutic potential of magnetic conjugates.

Abstract
BACKGROUND Apolipoprotein A-IV (apoA-IV) is an anti-atherogenic and antioxidative glycoprotein. Plasma apoA-IV levels are elevated in patients with primary chronic kidney disease (CKD) or renal failure. The association between apoA-IV and kidney function has not been investigated in the general population; therefore, we analysed this relationship in two large population-based cohorts. METHODS Plasma apoA-IV concentrations were measured in the Cooperative Health Research in the Region of Augsburg (KORA) F3 (n = 3159) and KORA F4 (n = 3061) studies. CKD was defined by the serum creatinine-estimated glomerular filtration rate (eGFR) and/or urine albumin-to-creatinine ratio. RESULTS Mean (±SD) apoA-IV concentration was 17.3 ± 4.7 mg dL(-1) in KORA F3 and 15.3 ± 4.3 mg dL(-1) in KORA F4. Fully adjusted linear mixed models revealed a significant association between apoA-IV concentration and lower eGFR in the third and fourth versus the first quartile of apoA-IV (β = -1.78 mL min(-1) /1.73 m², P = 0.0003 and β = -5.09 mL min(-1) /1.73 m², P = 2.83 × 10(-23) , respectively). ApoA-IV was significantly associated with an eGFR of <60 mL min(-1) /1.73 m², which was observed in 601 of the 6220 study participants [odds ratio (OR) 1.46, P = 0.03 and OR 3.47, P = 6.84 × 10(-15) for the third and fourth vs. the first quartile of apoA-IV, respectively]. Adding apoA-IV (fourth vs. first quartile) to the fully adjusted model significantly improved discrimination of eGFR <60 mL min(-1) /1.73 m² in KORA F3 [integrated discrimination improvement (IDI) 0.03, P = 1.30 × 10(-7) ] and KORA F4 (IDI 0.04, P = 1.32 × 10(-9) ) beyond classical risk factors for CKD. CONCLUSION The present analysis in two population-based cohorts revealed that high plasma apoA-IV concentrations are strongly associated with low kidney function defined by eGFR independent of major CKD risk factors. ApoA-IV appears to be an early marker of impaired kidney function.

Abstract
OBJECTIVE The aim of this study was to analyze the painfulness of a transvaginal ultrasound-guided follicle punction. MATERIAL AND METHODS Patients could choose to have either a neuroleptanalgesia or to be supported by the partner or a psychotherapist during the oocyte pick up. Based on a questionnaire, 277 patients tried to describe their level of pain in a horizontal alphanumeric scale divided in 15 categories, while other painful physical interacts could be quantified, too. Furthermore, patients were asked for the cause of sterility, former IVF-ET treatments and whether the partner or the psychotherapist looked after them during the oocyte retrieval. Statistical analysis was performed using a standardized computer program (Stat View, Abacus Concepts, USA). RESULTS The neuroleptanalgesia reduced the intensity of pain (average value of pain: 1.21 vs 9.26 without analgesia) in a significant way (p = 0.0001). Some patients compared the pain at oocyte retrieval with a bone fracture (8.08) or surgeries (10.12). More painful was a colic (13.67), infections (13.5), some diagnostic surgeries (12.09) or a delivery (11.91). Younger woman and patients with dysmenorrhea felt significantly more pain than others. Neither the presence of the partner or psychotherapist during punction nor the indication, number of previous IVF-ET treatments or a following pregnancy had any influence on the statistics. CONCLUSION Age as well as the rate of problems with menstruation should help the patient to decide on whether to have the follicle punction with or without anesthesia.

Abstract
Amplification of the Her-2/neu gene is accompanied by overexpression of its cell surface receptor product, c-erbB-2 protein. To investigate the degree of intratumoural heterogeneity we applied immunohistochemistry in primary Barrett's adenocarcinoma (BCA) (n = 6) and dysplasia adjacent to the carcinoma (n = 4). In addition, fluorescence in situ hybridisation (FISH) was performed in primary BCA (n = 5) and dysplastic areas (n = 4). For an objective evaluation digital image analysis and laser scanning microscopy were used. Five of six BCA showed a marked intratumoral heterogeneous staining pattern ranging from areas in which the tumour cells were negative or faintly positive to tumour areas with a strong staining of the entire membrane. Among the two dysplastic areas also a heterogeneous staining pattern was observed. FISH analysis revealed marked heterogeneity of intratumoral gene copy number changes in all BCA showing populations with different fractions of cells with polysomy, low level amplification and high level amplification. One dysplasia showed a minor population with Her-2/neu signal clusters. In conclusion, we observed marked intratumoural heterogeneity of c-erbB-2 protein overexpression and Her-2/neu gene copy number in the majority of the primary BCA analyzed. Digital image analysis and laser scanning microscopy were helpful in quantifying the variations in protein expression and DNA copy number in individual tumour cells. The observed heterogeneity could hamper the exact diagnostic determination of the c-erbB-2 status in small biopsies and possibly influence the effectiveness of a potential c-erbB-2 targeting therapy.
