Abstract
The aim of this study was to compare the effects of feeding homozygous β-casein A1 or A2 milk, on the body composition, milk intake, and growth of German Holstein (GH), German Simmental (GS), and crossbred dairy calves of both sexes during the first 2 weeks of life. A total of 104 calves (n = 54 female - f and n = 50 male - m) from the breed groups GH (n = 23), GS (n = 61), and crossbred GH x GS (CR; n = 20) were evaluated. Calves were weighed after birth and received colostrum ad libitum. On the second day, calves were alternately housed in pairs in double-igloo systems according to their random birth order and received either A1 milk (n = 52; 27 f / 25 m) or A2 milk (n = 52; 27 f / 25 m). They were offered 7.5 L/day, and the individual actual total milk intake (TMI) was recorded. Daily energy-corrected milk intake was also calculated based on the milk composition (fat and protein). Fecal scores were recorded daily. On d 15, visceral adipose tissue (VAT) volume was assessed by open magnetic resonance imaging (MRI) and dual-energy x-ray absorptiometry (DXA). In addition, fat and lean mass (g), as well as bone mineral content (g) and bone mineral density (g/cm2), were determined by DXA. The body composition, milk intake, and growth were similar between the 2 types of milk in the first 2 weeks of life. Female calves had more VAT and fat mass, but less lean mass than male calves. GH and CR calves had more VAT and less lean mass than GS calves. Male calves were heavier than female calves after birth and on d 15. The average days with diarrhea and diarrhea occurrence were similar between calves fed A1 and A2 milk and between both sex groups. GS calves presented slightly more days with diarrhea and increased odds of having diarrhea compared with GH calves, not differing from CR.

Abstract
INTRODUCTION The identification of blood biomarkers appears to be a means of improving diagnosis accuracy in Parkinson's disease (PD) and atypical parkinsonian syndromes (APS). We, therefore, evaluate the performance of neurodegeneration, oxidative stress and lipid metabolism plasma biomarkers to distinguish PD from APS. METHODS This was a monocentric study with a cross-sectional design. Plasma levels and discriminating power of neurofilament light chain (NFL), malondialdehyde (MDA) and 24S-Hydroxycholesterol (24S-HC) were assessed in patients with clinical diagnoses of PD or APS. RESULTS In total, 32 PD cases and 15 APS cases were included. Mean disease durations were 4.75 years in PD group and 4.2 years in APS group. Plasma levels of NFL, MDA and 24S-HC differed significantly between the APS and PD groups (P=0.003; P=0.009; P=0.032, respectively). NFL, MDA and 24S-HC discriminated between PD and APS (AUC=0.76688; AUC=0.7375; AUC=0.6958, respectively). APS diagnosis significantly increased with MDA level≥23.628nmol/mL (OR: 8.67, P=0.001), NFL level≥47.2pg/mL (OR: 11.92, P<0.001) or 24S-HC level≤33.4pmol/mL (OR: 6.17, P=0.008). APS diagnosis considerably increased with the combination of NFL and MDA levels beyond cutoff values (OR: 30.67, P<0.001). Finally, the combination of NFL and 24S-HC levels, or MDA and 24S-HC levels, or all three biomarkers' levels beyond cutoff values systematically classified patients in the APS group. CONCLUSION Our results suggest that 24S-HC and especially MDA and NFL could be helpful for differentiating PD from APS. Further studies will be needed to reproduce our findings on larger, prospective cohorts of patients with parkinsonism evolving for less than 3 years.

Macrophages are the most abundant immune cells in the myocardial tissue in steady state. The sterile inflammation caused by myocardial infarction triggers a massive immune reaction, which leads to a profound influx of neutrophils and monocytes. In the postacute phase of infarction macrophages play an essential role in reparative processes. Recently, it has become clear that macrophages in the heart have a dual developmental origin from embryonic and bone marrow (BM) hematopoiesis. In this study, we sought to investigate the contribution of embryonic derived macrophages to the cardiac macrophage pool in steady state as well as the acute and chronic phase after ischemia/reperfusion injury.
Methods/Results
To address the origin of macrophages in steady state we used different models of lineage tracing to determine the developmental origin of cardiac macrophages. Using FLT3-Cre mice and radiation-independent CD45.1/.2 bone marrow chimera, we found that the resident macrophage population in the heart is mainly independent of definitive hematopoiesis (approximately 70–80% of cardiac macrophages). The BM-dependent population on the other hand is replenished by blood-derived monocytes.
Further we used the radiation-independent CD45.1/.2 bone marrow chimera to characterize the origin of macrophages at different time points after I/R-injury. In the acute phase after myocardial infarction we observed a profound influx of BM-derived macrophages in the infarct region and also in the remote area. 30 days after I/R-injury the composition of the resident macrophage pool was mainly comprised of BM-independent macrophages, similar to steady state conditions. To address the role of BM-derived macrophages we used CCR2-ko mice, which have low numbers of inflammatory monocytes in peripheral blood. CCR2-ko mice showed reduced macrophage numbers in the acute phase after myocardial infarction. Using positron emission tomography we investigated the influence of CCR2-deficiency on cardiac function after I/R-injury. In comparison to WT mice, CCR2-ko mice showed a significantly increased infarct size. Cardiac remodeling, determined by end-diastolic volume, on the other hand was improved in CCR2-ko mice. The ejection fraction was similar in both groups.
Conclusion
The cardiac macrophage pool is mainly comprised of BM-independent macrophages. In response to I/R-injury monocyte-derived macrophages transiently enter the myocardium but do not persist in significant numbers over time. The influx of BM-derived macrophages after I/R-injury was reduced using CCR2-ko mice, which led to improved cardiac remodeling.
Our findings are of potential importance for understanding the cardiac immune response and for the therapeutic targeting of macrophages in inflammatory conditions.

Abstract
SummaryAim: Assessment of the clinical benefit of i.v. contrast enhanced diagnostic CT (CE-CT) compared to low dose CT with 20 mAs (LD-CT) without contrast medium in combined [18F]-FDG PET/CT examinations in restaging of patients with lymphoma. Patients, methods: 45 patients with non-Hodgkin lymphoma (n = 35) and Hodgkin's disease (n = 10) were included into this study. PET, LD-CT and CECT were analyzed separately as well as side-by-side. Lymphoma involvement was evaluated separately for seven regions. Indeterminate diagnoses were accepted whenever there was a discrepancy between PET and CT findings. Results for combined reading were calculated by rating indeterminate diagnoses according the suggestions of either CT or PET. Each patient had a clinical follow-up evaluation for >6 months. Results: Region-based evaluation suggested a sensitivity/specificity of 66/93% for LD-CT, 87%/91% for CE-CT, 95%/96% for PET, 94%/99% for PET/LD-CT and 96%/99% for PET/CE-CT. The data for PET/CT were obtained by rating indeterminate results according to the suggestions of PET, which turned out to be superior to CT. Lymphoma staging was changed in two patients using PET/ CE-CT as compared to PET/LD-CT. Conclusion: Overall, there was no significant difference between PET/LD-CT and PET/CE-CT. However, PET/CE-CT yielded a more precise lesion delineation than PET/LD-CT. This was due to the improved image quality of CE-CT and might lead to a more accurate investigation of lymphoma.

Abstract
BACKGROUND Ileostomy reversal is frequently performed in abdominal surgery. Postoperative complications after ileostomy reversal are encountered in around 20% of patients. Data regarding risk factors for reoperation after ileostomy closure are scarce. The purpose of this prospective trial was to determine risk factors for operative revision after ileostomy closure. MATERIALS AND METHODS This is an additional post hoc analysis of a two center prospective trial. After enrollment, patient characteristics and intraoperative details were analyzed. Patients were followed up at one postoperative visit before discharge and at a three months postoperative visit by standardized questionnaire. All reoperations occurring in the three months period after surgery were analyzed, and immediate reoperations which were directly related to the ileostomy reversal were analyzed separately. RESULTS 118 patients with elective ileostomy reversal were included in the trial. 12 out of 106 patients (11.3%) underwent any reoperation within three months after surgery (Clavien-Dindo grade IIIb). On multivariate analysis, anemia was associated with any reoperation p = 0.004; OR 6.93 (95% CI 1.37-30.07). Six out of 114 patients (5.3%) required an immediate reoperation (small bowel perforation, anastomotic leakage, postoperative ileus, deep wound infection) due to surgical complications directly related to the ileostomy reversal. Higher body mass index and anemia were associated with immediate reoperations (BMI: p = 0.038; OR 0.73 (95% CI 0.55-0.98); anemia: p = 0.001; OR 25.50 (95% CI 3.87-168.21). CONCLUSION Surgical complications after ileostomy reversal occurred to a substantial extent. Rate of reoperations was associated with anemia and high body mass index. Optimizing patients in terms of preoperative hemoglobin and BMI may reduce surgical complications after ileostomy closure.

Abstract
PURPOSE Data regarding length of hospital stay of patients undergoing ileostomy reversal are very heterogeneous. There are many factors that may have an influence on the length of postoperative hospital stay, such as postoperative wound infections. One potential strategy to reduce their incidence and to decrease hospital stay is to insert subcutaneous suction drains. The purpose of this study was to examine the influence of the insertion of subcutaneous suction drains on hospital stay and postoperative wound infections in ileostomy reversal. Risk factors for postoperative wound infection were determined. METHODS This is a randomized controlled two-center non-inferiority trial with two parallel groups. The total length of hospital stay as primary endpoint and the occurrence of a surgical site infection, the colonization of the abdominal wall with bacteria, and the occurrence of hematomas/seromas as secondary endpoints were monitored. RESULTS One hundred eighteen patients with elective ileostomy reversal were included. Fifty-nine patients were randomly assigned to insertion of a subcutaneous suction drain, and 59 patients were randomly assigned to receive no drain. After 3 months of follow-up, 50 patients in the group with drain and 53 patients in the group without drain could be analyzed. Median total length of hospital stay was 8 days in the SD group and 9 days in the group without SD (p = 0.17). Fourteen percent of patients with SD and 17 % without SD developed SSI, p = 0.68. Multivariate analysis revealed anemia (p < 0.01), intraoperative bowel perforation (p = 0.02) and resident (p = 0.04) or fellow (p = 0.048) performing the operation as risk factors for SSI. CONCLUSIONS This trial shows that the omission of subcutaneous suction drains is not inferior to the use of subcutaneous suction drains after ileostomy reversal in terms of length of hospital stay, surgical site infections, and hematomas/seromas.

Abstract
STUDY QUESTION Does the prevalence of adverse maternal and neonatal outcomes vary in women diagnosed with polycystic ovary syndrome (PCOS) according to different definitions? SUMMARY ANSWER A comparison of different criteria revealed that there is a substantial risk for perinatal complications in PCOS women, regardless of the used definition. WHAT IS KNOWN ALREADY Pregnant women with PCOS are susceptible to perinatal complications. At present, there are three main definitions for PCOS. So far, we are aware of only one study, which found that the elevated risk for complications varied widely depending on the different phenotypes and features but only considered a relatively small sample size for some of the phenotypes. STUDY DESIGN, SIZE, DURATION Retrospective matched cohort study. PARTICIPANTS/MATERIALS, SETTING, METHODS Data of primiparous women with PCOS according to ESHRE/ASRM 2003 criteria and healthy controls giving birth to neonates ≥500 g were included. A total of 885 women were analysed: out of 177 women with PCOS, 85 (48.0%) met the National Institutes of Health (NIH) 1990 criteria, another 14 (7.9%) featured the additional phenotypes defined by The Androgen Excess and PCOS Society (AE-PCOS) 2006 criteria, 78 (44.1%) were classified as PCOS exclusively by the ESHRE/ASRM 2003 definition, and 708 represented the control group. MAIN RESULTS AND THE ROLE OF CHANCE The prevalence of adverse maternal (49.4 versus 64.3 versus 60.3%, P = 0.313) and neonatal (27.1 versus 35.7 versus 23.1%, P = 0.615) outcomes did not differ within the three PCOS groups (ESHRE/ASRM, NIH, AE-PCOS, respectively). Compared with healthy controls, the risk for maternal complications was increased in PCOS patients [odds ratio (OR) 2.57; 95% confidence interval (CI) 1.82-3.64; P < 0.001] while there was no difference in neonatal complications (OR 0.83; 95% CI 0.56-1.21; P = 0.343). LIMITATIONS, REASONS FOR CAUTION A limitation of our study is its retrospective design and the relatively small sample size, particularly in the AE-PCOS subgroup. WIDER IMPLICATIONS OF THE FINDINGS Since women with PCOS have, regardless of the used definition, a high risk of maternal and neonatal complications they should be informed and advised to follow regular checks in units where problems can be detected early to allow specialized care.

Abstract
Cervical cancer screening was introduced in Germany 40 years ago and the incidence of cancer of the cervix has subsequently decreased by close to 70%. The remaining incidence of 5,600 cases per year represents only 2.8% of all newly occurring cases of cancer in women and these cases occur mainly in patients who do not participate in regular screening. Thus, cervical cancer screening by cytological smears has been proven to be successful. The structure of the German cancer screening program is characterized by decentralized organization, exclusive involvement of medical specialists such as gynecologists and pathologists and strict quality assurance. The recruitment is 50% on a yearly basis and the cumulative participation over 3 years reaches 79%. Since 2008 all laboratories are required to report complete data sets to local quality control agencies.The Joint Federal Committee in charge of evaluating new technologies in Germany mandated an inquiry into the possible role of screening by human papillomavirus (HPV) testing. According to this report published by the Institute for Quality Assurance and Efficiency in Healthcare there are indications for advantages. There are, however, no data in the literature as to possible disadvantages of HPV testing. A similar study for the US Preventive Services Task Force was published in May 2011 with almost identical conclusions.

Abstract
OBJECTIVES Amino acid insertions in the protease gene have been reported rarely, and mainly in patients receiving protease inhibitors (PIs). The aim of the study was to assess the long-term viro-immunological follow-up of HIV-infected patients harbouring virus with protease insertions. METHODS Cases of virus exhibiting protease insertions were identified in routine resistance genotyping tests. Therapeutic, immunological and virological data were retrospectively collected. RESULTS Eleven patients harbouring virus with a protease gene insertion were detected (prevalence 0.24%), including three PI-naïve patients. The insertions were mainly located between codons 33 and 39 and associated with surrounding mutations (M36I/L and R41K). The three PI-naïve patients were infected with an HIV-1 non-B subtype. Follow-up of these PI-naïve patients showed that the insert-containing virus persisted for several years, was archived in HIV DNA, and displayed a reduced viral replicative capacity with no impact on resistance level. Of the eight PI-experienced patients, 63% were infected with HIV-1 subtype B; one had been antiretroviral-free for 5 years and seven were heavily PI-experienced (median duration of follow-up 24 months; range 10-62 months). The protease insertion was selected under lopinavir in four patients and under darunavir in one, in the context of major PI-resistance mutations, and following long-term exposure to PIs. The insert-containing virus persisted for a median of 32 months (range 12-62 months) and displayed no specific impact on phenotypic resistance level or viral replicative capacity. CONCLUSION Our data, obtained during long-term follow-up, show that insertions in the protease gene do not seem to have an impact on resistance level. This finding supports the recommendation of PI-based regimens, although further work is required to confirm it.

Abstract
UNLABELLED The vitronectin receptor integrin alphavbeta3 promotes angiogenesis by mediating migration and proliferation of endothelial cells, but also drives fibrogenic activation of hepatic stellate cells (HSCs) in vitro. Expecting antifibrotic synergism, we studied the effect of alphavbeta3 inhibition in two in vivo models of liver fibrogenesis. Liver fibrosis was induced in rats by way of bile duct ligation (BDL) for 6 weeks or thioacetamide (TAA) injections for 12 weeks. A specific alphavbeta3 (alphavbeta5) inhibitor (Cilengitide) was given intraperitoneally twice daily at 15 mg/kg during BDL or after TAA administration. Liver collagen was determined as hydroxyproline, and gene expression was quantified by way of quantitative polymerase chain reaction. Liver angiogenesis, macrophage infiltration, and hypoxia were assessed by way of CD31, CD68 and hypoxia-inducible factor-1alpha immunostaining. Cilengitide decreased overall vessel formation. This was significant in portal areas of BDL and septal areas of TAA fibrotic rats and was associated with a significant increase of liver collagen by 31% (BDL) and 27% (TAA), and up-regulation of profibrogenic genes and matrix metalloproteinase-13. Treatment increased gamma glutamyl transpeptidase in both models, while other serum markers remained unchanged. alphavbeta3 inhibition resulted in mild liver hypoxia, as evidenced by up-regulation of hypoxia-inducible genes. Liver infiltration by macrophages/Kupffer cells was not affected, although increases in tumor necrosis factor alpha, interleukin-18, and cyclooxygenase-2 messenger RNA indicated modest macrophage activation. CONCLUSION Specific inhibition of integrin alphavbeta3 (alphavbeta5) in vivo decreased angiogenesis but worsened biliary (BDL) and septal (TAA) fibrosis, despite its antifibrogenic effect on HSCs in vitro. Angiogenesis inhibitors should be used with caution in patients with hepatic fibrosis.

Abstract
Summary
Ni- and Co-nanoparticles of average sizes of about 4 to 10 nm were produced by “physical” means with the cluster source LUCAS based upon laser evaporation into seeding gas and adiabatic expansion into an UHV experimentation chamber. They were deposited and subsequently oxidized in situ at about 400 °C.
The structures of the nanos were characterized by HRTEM and chemically analyzed by EFTEM. Clear core/shell structures were established with crystalline metallic core and crystalline oxide shell of final thickness of about 2 nm. In one sample it might be that the shell is amorphous.
An analysis of magnetic properties by SQUID was performed at temperatures between 5 and 300 K and for three different states of oxidation. Surprisingly strong influences of magnetic defects in the nominally (but probably incompletely saturated) antiferromagnetic oxide layers were observed which result in additional exchange anisotropy, in drastic exchange bias shifts of the hystereses and, in one sample, in a second hysteresis loop contribution. In all samples we found suppression of the superparamagnetic state.
The special sample with two loop contributions was numerically evaluated (by co-author H. Krenn).
In the final chapter a method is proposed how to transform these “physically” produced magnetic nanoparticles into a ferrofluid of well known composition.

Abstract
AIM Assessment of the clinical benefit of i.v. contrast enhanced diagnostic CT (CE-CT) compared to low dose CT with 20 mAs (LD-CT) without contrast medium in combined [(18)F]-FDG PET/CT examinations in restaging of patients with lymphoma. PATIENTS, METHODS 45 patients with non-Hodgkin lymphoma (n=35) and Hodgkin's disease (n=10) were included into this study. PET, LD-CT and CE-CT were analyzed separately as well as side-by-side. Lymphoma involvement was evaluated separately for seven regions. Indeterminate diagnoses were accepted whenever there was a discrepancy between PET and CT findings. Results for combined reading were calculated by rating indeterminate diagnoses according the suggestions of either CT or PET. Each patient had a clinical follow-up evaluation for >6 months. RESULTS Region-based evaluation suggested a sensitivity/specificity of 66/93% for LD-CT, 87%/91% for CE-CT, 95%/96% for PET, 94%/99% for PET/LD-CT and 96%/99% for PET/CE-CT. The data for PET/CT were obtained by rating indeterminate results according to the suggestions of PET, which turned out to be superior to CT. Lymphoma staging was changed in two patients using PET/CE-CT as compared to PET/LD-CT. CONCLUSION Overall, there was no significant difference between PET/LD-CT and PET/CE-CT. However, PET/CE-CT yielded a more precise lesion delineation than PET/LD-CT. This was due to the improved image quality of CE-CT and might lead to a more accurate investigation of lymphoma.

Abstract
Recent findings about the pathomechanisms of tumour angiogenesis have led to new therapeutic options in the treatment of malignant tumours. During the development of anti-angiogenic drugs, reporting ranged from healing cancer to completely ineffective drugs. In 2003 the first anti-angiogenic drug was approved. Several anti-angiogenic drugs are still in the clinical phase of development. In contrast to identifying the maximal tolerable dose, determination of the optimal biological dose--reaching biological activity at lower doses--has become the main target in the early development of anti-angiogenic agents. This has been evaluated by different biomarker techniques. As a new standard in anti-tumour treatment, a better understanding of imaging in the treatment monitoring for anti-angiogenic agents is important. Studies of tumour angiogenesis by tissue sampling rely on invasive procedures, adequate sampling and painstaking estimation of histological microvessel density. Attempts to develop wound healing assays to correlate angiogenesis in wounds with angiogenesis in tumour have been made but are still considered invasive and correlation of healthy with malignant tissue is still of limited validity. Several soluble markers of tumour angiogenesis were detected in various malignant diseases and were evaluated for assessing their use as surrogate markers in tumour angiogenesis. Further, soluble markers were investigated for visualizing them as imaging tools. Combining both, new soluble markers and imaging techniques, developing anticancer drugs and monitoring of therapy success becomes a dynamic process in which finally the patients' individual response can be achieved soon. Time-consuming delays for anatomically based restaging procedures can be avoided. Characterization of soluble biomarkers as well as different imaging techniques such as ultrasound, computed tomography (CT), magnetic resonance imaging and positron emission tomography combined with or without CT are reviewed in this manuscript.

Abstract
PURPOSE Anti-inflammatory activity of an antiglaucoma drug may be an advantage for long-term treatment of glaucoma since it may reduce the risk of treatment-related inflammatory processes in outer compartments of the eye and probably also prevent or delay progression of glaucomatous retinal neurodegeneration. In this study, the effect of GLC756, a novel mixed dopamine D 2 receptor agonist and dopamine D 1 receptor antagonist, and timolol on endo-toxin-induced cytokine tumor necrosis factor-alpha (TNF-alpha) release in serum was examined. METHODS For endotoxin-induced TNF-alpha release, 8-week-old Lewis rats were intravenously injected with 160 microg lipopolysaccharide (LPS) from Salmonella typhimurium. GLC756, timolol, or betamethasone were either systemically (1 mg/kg SC for 5 days) or topically (0.4%, 0.5%, and 0.1%, respectively, 20 microL eye drops given 16 times over 48 hours in left and right eye) administered. TNF-alpha was measured in serum 2 and 48 hours after LPS induction. RESULTS A marked TNF-alpha increase in serum was found 2 hours after LPS induction. Administration of GLC756 and betamethasone, systemically and topically, decreased TNF-alpha release. However, due to large scattering of mean values only the effect of systemically administered GLC756 was statistically significant. In contrast, timolol increased TNF-alpha values stronger than LPS alone. CONCLUSIONS The significant suppression of LPS-induced TNF-alpha increase by GLC756 suggests an additional anti-inflammatory potential of the dopaminergic compound in the treatment of glaucoma.

Abstract
Results of multi-year bone observations in crewmembers of long-term (6 to 14 mos.) Salyut and Mir missions have been summarized. The theoretical expectation of bone losses (mineral bone density, MBD) was consistent only in the trabecular of the lower skeleton (lumbar spine, femur proximal epiphysis, pelvis). The upper skeleton bones (skull, cervical spine) demonstrated a clears-defined trend toward an increase in mineral content. There is a direct dependence of MBD losses on a skeleton bone position relative to the gravity vector and bone structure. Post-flight MBD did not, as a rule, deviate from the WHO-defined limits (T-criterion); in several instances MBD loss was qualified as local osteopenia. Shifts in MBD, same as MBD recovery rate, vary with subjects and, therefore, deny their dependence on flight duration. By and large, MBD shifts are interpreted as a functional adaptation of bone tissue to changing mechanic demands.

Abstract
A closer analysis was made of all postmortems at the Benjamin Franklin Campus of the Institute of Forensic Medicine performed on juveniles who committed suicide at the age of 20 or below in the period from 1998 to 2003. A double suicide of a young couple, who met on the Internet and agreed on the procedure to be followed up to the act itself, which took place in Berlin, is presented as a representative case. The authors emphasise that in view of the danger of emulation, the media should exercise restraint in describing concrete details especially when reporting about suicides of juveniles.
