Abstract
Appropriate stallion semen handling is of great importance in equine artificial insemination (AI) industry. Optimal treatment of AI doses is aiming for best sperm preservation by excluding strong environmental influences and adding media that favour sperm survival. One method widely used in stallion sperm handling is the rotation of liquid-preserved semen samples on roller benches during storage. As previous studies in boars give rise to the fact that rotation should not be considered beneficial for spermatozoa anymore, the present study investigated the influence of continuous rotation of diluted stallion AI portions on sperm quality. Ejaculates (n = 15) were collected at a German AI centre and diluted with the two extenders EquiPlus and Gent (Minitüb GmbH) to a final concentration of 50 × 106 sperm/mL. Afterwards, samples were placed separately on roller benches at 5°C in the dark, obtaining a rotation frequency of 5 revolutions per minute (rpm) and 36 rpm for four consecutive days following a split-sample design. Both groups were analysed daily in comparison to a control group (0 rpm) with an extended spectrum of spermatological methods including computer-assisted sperm analysis and flow cytometry. Statistical analyses were based on the calculation of generalized linear mixed models for each sperm parameter. The research revealed a decrease in sperm quality parameters of rotated samples compared to non-rotated control groups, visible in total sperm motility (p < .001), decreased thermo-resistance (p < .01) and a drop in pH (p < .001). Interestingly, no differences (p > .05) were detected between rotation frequencies of 5 and 36 rpm. We conclude that the fertilizing capacity of stallion semen was negatively affected by rotation during storage in vitro, irrespective of the rotation frequency. Further studies need to investigate whether field fertility in horses is similarly affected by semen rotation on roller benches in vivo.

Abstract
Since the stallion acrosome is very small compared to other species and cannot be properly assessed without additional staining, several labelling techniques were developed to facilitate its assessment. The aim of this study was to compare the Spermac stain (Minitüb GmbH) and a PNA/PSA/PI triple-staining detected by flow cytometry with regard to method agreement for detecting non-intact acrosomes within two different extenders. For this purpose, eighteen stallion ejaculates were split in half and diluted with the semen extenders EquiPlus or Gent (Minitüb GmbH) to a final concentration of 50 × 106 sperm/mL, respectively. Subsequently, 126 semen samples were stained with both methods between 4 and 240 h (mean: 63.8 ± 48.9 h) after semen collection. Calculated Intraclass correlation coefficients revealed excellent correlations between both methods for EquiPlus (r = .77, p < .001) and fair correlations for Gent (r = .49, p < .001). Interestingly, flow cytometry detected more non-intact acrosomes in EquiPlus than in Gent (p < .001), whereas the Spermac stain showed no differences (p = .902) between extenders. The poorer method agreement in Gent could be caused by egg yolk artefacts, which made interpretation difficult, so flow cytometry might be preferred. The differences in detected non-intact acrosomes between extenders highlighted the importance of establishing adapted laboratory protocols for different extender types in order to generate comparable results.

Abstract
The aim of this study was to develop prediction models for total sperm motility, morphological abnormalities and sperm output based on 1,551 ejaculate records of 58 Holstein bulls. The data was collected from September 2019 to November 2020 in a single artificial insemination (AI) center located in Eastern Germany. Factors considered for the prediction models include barn climate conditions, semen collector, number of false mounts, libido, semen collection frequency, breed and age (10-74 months). In this study, the prediction models Lasso, Group Lasso and Gradient Boosting were evaluated. The best model for each sperm quality parameter was chosen using cross validation. The models were estimated with five algorithms for sperm motility and sperm morphology and three algorithms for the number of total sperm per ejaculate (sperm output). For sperm motility and morphology a binary classification algorithm was applied, reaching an accuracy of over 80% for all models. For sperm output, no such classification was used and the only variable selected by all three algorithms was age. Furthermore, for sperm morphology, climate variables were frequently selected. Additionally, network diagrams from Group Lasso show the interdependencies between the major variable groups influencing sperm motility and morphology. In conclusion, the implementation of such prediction tools could help AI centers to optimize management factors and stabilize bull semen production in the future.

Abstract
This review is part of the Festschrift in honor of Dr. Duane Garner and provides an overview of current techniques for cooled storage of semen from livestock animals. The first part describes the current state of the art of liquid semen preservation in boars, bulls, and stallions, including the diluents, use of additives, processing, temperature, and cooling of semen. The species-specific physiology and varying extents of cold shock sensitivity are taken into consideration. In addition, factors influencing the quality of cooled-stored semen are discussed. Methods, trends, and the most recent advances for improving sperm quality during cold-temperature storage are highlighted and their respective advantages and disadvantages are contrasted. There has been much progress in recent years regarding cold-temperature storage of boar sperm and there is great potential for a large-scale use to replace the current 17 °C temperature storage regime and the associated use of antibiotics in the future. For stallion sperm, there is an opposite trend away from previous low-temperature storage towards storage at higher temperatures to increase sperm viability and longevity. In bulls, liquid storage of sperm is mostly used in the seasonal dairy production systems of New Zealand and Ireland, but with further research focusing on shelf-live elongation of liquid preserved sperm, there is potential for an application in breeding programs worldwide.

Abstract
Introduction ADHD patients often report that they are being flooded by sensory impressions. Studies investigating sensory processing show hypersensitivity for sensory inputs across the senses. While studying unimodal signal-processing is relevant and well-suited in a controlled laboratory environment, our daily interaction with our environment does not occur merely unimodal. A complex interplay of the senses is necessary to form a unified percept. In order to achieve this, the unimodal sensory modalities are bound together in a process called multisensory integration (MI). Objectives In the current study we investigate MI in an adult ADHD sample accompanied by resting-state functional magnetic resonance imaging (RS-fMRI). Methods Twenty-five ADHD patients and twenty-four healthy controls were recruited. MI was examined using the McGurk effect, where - in case of successful MI - incongruent speech-like phonemes between visual and auditory modality are leading to a perception of a new phoneme. Mann-Whitney-U test was applied to assess statistical differences between groups. Resting-state functional MRI was acquired to realize a seed-to-voxel analysis Results Susceptibility to MCGurk was significantly lowered for ADHD patients (ADHDMdn:5.83%, ControlsMdn:44.2%, U= 160.5, p=0.022, r=-0.34). When ADHD patients integrated phonemes, reaction times were significantly longer (ADHDMdn:1260ms, ControlsMdn:582ms, U=41.0, p<.000, r= -0.56). Seeded medio temporal gyrus was negatively associated in functional connectivity to primary auditory cortex, inferior frontal gyrus, precentral gyrus, and fusiform gyrus. Conclusions MI seems to be deficient for ADHD patients for stimuli that need late attentional allocation. This finding is supported for higher functional connectivity from unimodal sensory areas to polymodal, MI convergence zones for complex stimuli. Disclosure No significant relationships.

Abstract
Continuous manufacturing is becoming more important in the biopharmaceutical industry. This processing strategy is favorable, as it is more efficient, flexible, and has the potential to produce higher and more consistent product quality. At the same time, it faces some challenges, especially in cell culture. As a steady state has to be maintained over a prolonged time, it is unavoidable to implement advanced process analytical technologies to control the relevant process parameters in a fast and precise manner. One such analytical technology is Raman spectroscopy, which has proven its advantages for process monitoring and control mostly in (fed-) batch cultivations. In this study, an in-line flow cell for Raman spectroscopy is included in the cell-free harvest stream of a perfusion process. Quantitative models for glucose and lactate were generated based on five cultivations originating from varying bioreactor scales. After successfully validating the glucose model (Root Mean Square Error of Prediction (RMSEP) of ∼0.2 g/L), it was employed for control of an external glucose feed in cultivation with a glucose-free perfusion medium. The generated model was successfully applied to perform process control at 4 g/L and 1.5 g/L glucose over several days, respectively, with variability of ±0.4 g/L. The results demonstrate the high potential of Raman spectroscopy for advanced process monitoring and control of a perfusion process with a bioreactor and scale-independent measurement method.

Abstract
Introduction During surgery in patients with labyrinthine fistula the mandatory complete removal of the cholesteatoma while preserving inner ear and vestibular function is a challenge. Options so far have been either the complete removal of the cholesteatoma or leaving the matrix on the fistula. We evaluated an alternative “under water” surgical technique for complete cholesteatoma resection, in terms of preservation of postoperative inner ear and vestibular function. Methods From 2013 to 2019, 20 patients with labyrinthine fistula due to cholesteatoma were operated. We used the canal wall down approach and removal of matrix on the fistula was done as the last step during surgery using the “under water technique”. The pre and postoperative hearing tests and the vestibular function were retrospectively examined. Results There was no significant difference between pre and post-operative bone conduction thresholds; 20% experienced an improvement of more than 10 dB, with none experiencing a postoperative worsening of sensorineural hearing loss. Among seven patients who presented with vertigo, two had transient vertigo postoperatively but eventually recovered. Conclusion Our data show that the “under water technique” for cholesteatoma removal at the labyrinthine fistula is a viable option in the preservation of inner ear function and facilitating complete cholesteatoma removal.

Abstract
INTRODUCTION In diagnostic angiographic procedures, the knowledge of arterial variations in the femoral artery (FA), deep femoral artery (DFA) and lateral and medial circumflex femoral arteries (LCFA, MCFA) has a great impact. MATERIAL AND METHODS The frequency of branching patterns of these arteries was investigated in 111 thighs of body donors. Gender and side differences were analyzed statistically. RESULTS The median distance of separation of the DFA from the FA in relation to the inguinal ligament (IL) was 3.29 cm. High origins (1-2 cm below IL) and middle origins (3-5 cm below IL) of the DFA were found in an equal distribution of 39.3% and 41.1%, respectively. Low origins (6-10 cm below IL) were rare (19.6%) but showed a tendential significance toward expression in males (p = 0.096). The origin of the LCFA from the FA (19.8%) or DFA (70.2%) are in line with the findings of other groups. The origin of the MCFA from FA (14.4%) or DFA (74.7%) showed that circumflex femoral arteries arose mostly from DFA. A trifurcation of the FA into the DFA, LCFA and MCFA was only observed in 9.9% and, therefore, less frequently than reported by others. Branches of the femoral nerve (FN) passed mostly anterior (46.4%) or anterior and posterior (47.8%) to the LCFA. The rare constellation of branches of FN passing only posterior to the LCFA (5.8%) showed a tendential significance to left side expression (p = 0.084). CONCLUSIONS Taken together, this is the first classification of the median distance of separation of the DFA from the FA in relation to the IL in three defined groups. The knowledge of DFA branching pattern is essential for recent therapy options of cardiac diseases using a femoral artery access: transcatheter aortic valve replacement, catheter-based miniaturized ventricular assist device and veno-arterial extracorporal membrane oxygenation. The variant topography of the branches of FN in relation to LCFA should be kept in mind when harvesting an anterolateral thigh flap.

Abstract
Secretly taken photographs of livestock production systems, representing animal welfare violations, regularly appear in the media and initiate discussions as to the legitimacy of overriding legal regulations in order to document animal welfare standards. This paper focuses on the public
perspective and compares different forms of undercover investigation, weighing animal welfare against the invasion of farmers' privacy. For this purpose, an exploratory online survey was conducted in Germany (n = 292). Participants were carefully selected to ensure that age range, education
level and sex reflected the distribution of the society as a whole. In a split-sample survey, each participant was confronted with three scenarios. The scenarios were mapped using pictures showing various levels of farm conditions combined with small information segments describing the invasion
of farmers' privacy. Participants evaluated the scenarios for their perceived legitimacy and whether entering the premises should be punished. All forms of undercover investigation were perceived as legitimate by most respondents. Perceived legitimacy was considerably higher when obvious animal
abuse was uncovered. Apart from where damage to property was involved, which was mostly considered as unacceptable, harsher punishment for animal welfare organisations generally obtained little social approval. The public's increasing awareness of farm animal welfare overruled social norms
regarding farmers' privacy, and thereby demonstrated the importance of animal welfare in society. Approval of undercover investigations indicated that changes in housing and handling conditions as well as improvement in control mechanisms are necessary to increase animal welfare and thus public
acceptance of livestock production.

Abstract
Abstract
Background
Heart failure (HF) and atrial fibrillation (AF) impair the prognosis when they occur concomitantly. Recent telemedical studies suggest that HF patients with AF may derive a greater benefit from telemedicine care but the results are inconsistent. The rate of newly detected AF in HF patients by daily non-invasive electrocardiogram (ECG) monitoring is unknown and a possible influence on the outcome of remote patient management (RPM) remains unclear.
Purpose
We aimed to investigate the detection of new atrial fibrillation in patients assigned to RPM in comparison to patients assigned to usual care (UC) in the
TIM-HF2 trial.
Methods
The prospective, multicentre and controlled TIM-HF2 trial randomised 1538 patients (765 RPM, 773 UC). All patients had a 12-channel ECG at baseline and after one year at the final study visit. Patients who were assigned to RPM additionally transmitted a daily ECG to the telemedical centre (TMC). We excluded all patients with pacemaker including implantable cardioverter defibrillator (ICD) or cardiac resynchronisation therapy (CRT) in the baseline ECG, leaving 879 patients for analysis (RPM: 442 and UC: 437). The patients were stratified into patients with SR and patients with AF according to the rhythm documented at baseline. The primary endpoint of this analysis was newly documented AF within one year after randomisation. We analysed the daily to the telemedical centre transmitted ECGs of patients assigned to RPM with the documented rhythm status of the ECGs performed at the final study visit of patients assigned to UC.
Results
569 patients had SR and 310 patients had AF at baseline. The proportion of patients with AF was nearly the same in the RPM (159, 36.0%) and the UC (151, 34.6%) group. 68 patients (24.0%) were detected with new atrial fibrillation in the RPM group compared to 22 patients (7.8%) in the UC trial arm during the one-year follow-up (p<0.001, number needed to screen 6).
Conclusion
In patients with heart failure and daily ECG transmission, atrial fibrillation was detected three times more frequently in comparison to usual care within one year.

Abstract
New ways of predicting sperm quality and output performance in young artificial insemination (AI) boars are important for breeding companies to ensure that the pubertal boars delivered to the AI studs have a high chance of meeting minimum quality standards to be used for insemination and therewith dissemination of desirable characteristics. The aim of the current study was to characterize the testicular development of 218 pubertal Piétrain boars (Line 408, Pig Improvement Company) to identify traits with predictable characteristics relative to their sperm quality as an adult AI boar. Scrotum, testes and epididymis were examined ultrasonographically at day (d) 100 (on-test) and 170 (off-test) followed by a computer-assisted grayscale analysis (GSA). Over the test period, paired testicular volume increased 7.3-fold from 22.7 ± 10.8 cm3 to 166.6 ± 62.2 cm3. The right testis was significantly (P = 0.014) larger than the left one at the off-test. Based on the sperm quality (ejaculate volume, sperm concentration, total sperm number, morphologically abnormal sperm and total sperm motility at day 3 of semen storage), 82.11% (n = 179) of the boars were classified as "productive" boars. These boars had a significantly (P = 0.039) larger paired testicular volume than "non-productive" boars (45.9 ± 19.9 cm3vs. 38.5 ± 12.6 cm3) at the on-test. For the right testis at on-test, significant differences for the standard deviation of mean gray value (P = 0.022), area under the curve (P = 0.004) and mean gradient value (GRAD, P = 0.030) regarding the future sperm production capacity (SPC) were shown. At off-test, there was a significant difference for minimum gray value (MIN GV, P = 0.003) and mean gray value (P = 0.001) related to SPC. To find SPC related cut-off values for GSA data, a two segmental non-linear regression analysis was carried out indicating breakpoints for GRAD ≥12 and MIN GV ≥ 40 for boars with low SPC. Off-test boars with MIN GV ≥ 40 showed a 2.4 higher risk to display low SPC (Odds ratio = 2.4 [1.1, 5.4]; P = 0.024). The results may enable breeding companies to include new sperm quality associated traits in their boar testing and selection programs.

Abstract
Abstract
Background
The Swiss School of Public Health's (SSPH+) Global PhD Programme in Public Health Sciences (GlobalP3HS) is a doctoral programme, promoting transnational education and mobility co-funded by the European Union's Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 801076. Students from abroad absolve a PhD training at one of the 12 SSPH+ partner universities in Switzerland.
Objectives and Methods
GlobalP3HS aims to train the next generation of public health leaders in both the academic and non-academic sector. Specific attention was given to PhD studies under the “sandwich model” (SM) which fosters research of students from low/middle income countries (LMIC) conducting LMIC-relevant PhD studies in collaboration with an LMIC-based academic institution. The SM targets at increasing chances for LMIC-based postdoctoral careers. The five year programme (October 2018 to September 2023) provides 42-months fellowships to profit from PhD programmes at a Swiss university. Top-scoring candidates were selected in a transparent, merit-based procedure by an international jury, considering students' background and motivation; innovation; methodological quality; public health relevance; and feasibility of the proposed research.
Results
Out of 342 valid applications, the jury scored 147 as eligible (score 8-10). In total, 53 students (31 women) were successful in matching up with co-funding supervisors. PhD-students from 31 countries representing all global regions, including 21 PhD under the SM, are enrolled at seven Swiss SSPH+ partner universities.
Conclusions
GlobalP3HS is an innovative solution to strengthen global research collaborations. The SM abates “brain drain” as it clears the path for successful careers in LMICs, where graduates become change makers capitalising on solid academic collaborations with the SSPH+ network.
Key messages
GlobalP3HS trains PhD fellows in public health sciences to become change-making leaders in academic institutions and public health organisations. GlobalP3HS is an initiative from the Swiss School of Public Health strengthening equitable, fair, balanced, and innovative inter-university and global partnerships.

Abstract
Several domestic and wildlife species have been shown to possess antibacterial defenses in their ejaculate most probably in order to increase the fertilization success and protect against sexually transmitted pathogens. However, very little is known about the consequences and factors influencing the differences within and between species as far as ejaculate-associated immunity. In the present study, we have analyzed bacterial killing activity (BKA) against Escherichia (E.) coli and Staphylococcus (S.) aureus as well as lysozyme concentrations (LC) in seminal plasma from 60 Fleckvieh bulls. Further, sperm quality and its association with BKA and LC were determined. Twenty percent of the individuals displayed BKA against both bacteria, 78.3% against S. aureus only and 1.7% of the bulls did not indicate any BKA in seminal plasma. No bulls with seminal plasma BKA only against E. coli were identified; implying that 80.0% of the tested bulls had no ejaculate associated defense mechanisms against this gram-negative bacterial species in place. This is in striking contrast to results of Pietrain boars within our previous study, in which 42.8% of the 119 boars expressed an antibacterial activity against E. coli in seminal plasma, 10.9% amongst them with BKA against E. coli only. LC was higher in the bull group with BKA against both bacteria (1.2 ± 0.6 μg/mL) compared to the group with BKA against S. aureus only (0.7 ± 0.3 μg/mL), but - if calculated over all individuals - LC in bulls (0.8 ± 0.4 μg/mL) was lower compared to boars (2.4 ± 1.2 μg/mL). LC showed positive correlations to the age of the bulls and sperm quality as well as a negative relation to bacterial load in raw semen although the highest bacterial contamination was found in animals with seminal plasma BKA against both strains. We discuss the obtained results with regards to possible differences within the microbiome of female and male genital tracts and the reproductive strategies (vaginal vs. uterine depositors) in these two livestock species. Besides identifying the responsible molecules, future phylogenetically controlled comparative studies are needed for a better understanding of the evolution of species differences in ejaculate-associated antibacterial defenses.

Abstract
BACKGROUND The association between anthropometric variables and cardiovascular disease (CVD) risk among Africans is unclear. We examined the discriminative ability of anthropometric variables and estimate cutoffs for predicting CVD risk among Africans. METHODS The Research on Obesity and Diabetes among African Migrants (RODAM) study was a multisite cross-sectional study of Africans in Ghana and Europe. We calculated AHA/ACC Pooled Cohort Equations (PCE) scores for 3661 participants to ascertain CVD risk, and compared a body shape index (ABSI), body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), Relative Fat Mass (RFM), and Waist to Height Ratio (WHtR). Logistic regression and receiver operating curve analyses were performed to derive cutoffs for identifying high predicted CVD risk (PCE score ≥7.5%). RESULTS Among men, WC (adjusted Odds Ratio (aOR): 2.25, 95% CI; 1:50-3:37) was strongly associated with CVD risk. Among women, WC (aOR: 1.69, 95% CI: 1:33-2:14) also displayed the strongest association with CVD risk in the BMI-adjusted model but WHR displayed the strongest fit. All variables were superior discriminators of high CVD risk in men (c-statistic range: 0.887-0.891) than women (c-statistic range: 0.677-0.707). The optimal WC cutoff for identifying participants at high CVD risk was 89 cm among men and identified the most cases (64%). Among women, the recommended WC cutoff of 94 cm or WHR cutoff of 0.90 identified the most cases (92%). CONCLUSIONS Anthropometric variables were stronger discriminators of high CVD risk in African men than women. Greater WC was associated with high CVD risk in men while WHR and WC were associated with high CVD risk in women.

Abstract
The best electron beam transport through a linear induction accelerator (LIA) is achieved when the beam is well centered on the magnetic axis of the focusing solenoids. Since the beam may be injected offset from, or at an angle to, the centerline, dipole magnets are usually provided as a means to steer the beam and center it. Steering may be accomplished by trial and error, but this is very time consuming, especially for accelerators with a low repetition rate for beam position measurements and dipole adjustments. This article presents a steering method requiring a minimal number of measurements and adjustments to position the beam at any desired location, including positioning on the centerline.

Abstract
Antibiotics are mandatory components of semen extenders for the control of bacterial contamination and growth. The increasing rate of worldwide resistance to conventional antibiotics in semen preservation media requires the development of new antimicrobial alternatives. This review provides an update on this topic and also highlights the improvement of hygiene in Artificial Insemination centers in order to prevent the development of bacterial resistance. Ideas are shared on future diagnostic tools for bacterial contamination in Artificial Breeding. Finally, new methods to remove or reduce bacteria in semen will be discussed.

Abstract
Abstract
This paper presents results of a collaborative trial study (IUPAC project No. 650/93/97) involving 29 laboratories in 13 countries applying a method for detecting genetically modified organisms (GMOs) in food. The method is based on using the polymerase chain reaction to determine the 35S promoter and the NOS terminator for detection of GMOs. Reference materials were produced that were derived from genetically modified soy beans and maize. Correct identification of samples containing 2% GMOs is achievable for both soy beans and maize. For samples containing 0.5% genetically modified soy beans, analysis of the 35S promoter resulted also in a 100% correct classification. However, 3 false-negative results (out of 105 samples analyzed) were reported for analysis of the NOS terminator, which is due to the lower sensitivity of this method. Because of the bigger genomic DNA of maize, the probability of encountering false-negative results for samples containing 0.5% GMOs is greater for maize than for soy beans. For blank samples (0% GMO), only 2 false-positive results for soy beans and one for maize were reported. These results appeared as very weak signals and were most probably due to contamination of laboratory equipment.

Abstract
Antibiotic agents such as gentamicin represent essential components of semen extenders in order to reduce bacterial contamination. But antibiotic resistance increases and AI centers start utilizing antibiotic agents which are more potent. Therefore, a shift to preventing bacterial contamination has to take place. In this study, we could demonstrate that hygiene is a tool capable of reducing bacterial load. In order to analyze 1434 extended semen samples and nine specially established hygienic critical control points (HCCPs, n = 828), 92 quality control audits have been carried out in a time period from 2012 until 2019 in 28 European AI centers. The results show the process of introducing a basic hygienic standard in audit 1 (2012/2013) and 2 (2014/2015) and the resulting achievements by means of improved hygienic conditions in audit 3 (2016/2017) and 4 (2018/2019). Within the scope of audit 1, 19% of the semen samples were contaminated with bacteria (cutoff ≥100 colony-forming units/mL). Audit 2 showed a bacterial load of 13.6% whereas during audit 3 and 4 very low bacterial contamination rates were recorded (4.5 and 5.5%, respectively). In the same manner, analysis of hygiene at different CCPs during semen production showed a decrease in all average HCCP-scores (score 1-6) comparing audit 4 to 1. By regression analysis we could show a significant audit-dependent association of the bacterial contamination in semen samples and hygiene of HCCPs. Furthermore, analysis of the odds ratio (OR) reveals that the bacterial contamination of certain HCCPs poses an increased risk of receiving bacterially contaminated semen samples (filling machine: OR = 3.02, P = 0.06; extender: OR = 8.97, P < 0.001; inner face of dilution tank lids: OR = 3.14, P = 0.09). Around 60% of the variance of the bacterial contamination in semen samples could be explained by hygienic conditions at different control points and their interaction with audit period and AI center. Antimicrobial agents are essential to protect human and animal health but excessive or inappropriate use can lead to the emergence of resistant bacteria. As shown in our study, hygiene management can significantly reduce bacterial contamination and is therefore capable of preventing antibiotic resistance.

Abstract
Abstract
An immunoassay for detection of a specific genetically modified soybean (Roundup-Ready®) was validated on dried soybean powder in an interlaboratory study. Different percentages of genetically modified soybeans in nonmodified soybean matrix were evaluated in a blind study. Thirty-eight laboratories from 13 countries participated. The immunoassay was evaluated for 2 endpoints: (1) To give a semiquantitative result, i.e., determination of a given sample above or below a given threshold, or (2) to compute a quantitative result, i.e., percentage of genetically modified soybeans in the sample. Semiquantitative results showed that a given sample which contained <2% genetically modified soybeans was identified as below 2% with a 99% confidence level. Quantitative use of the assay resulted in a repeatability (r) and reproducibility (R) that were computed to be RSDr = 7% and RSDR = 10%, respectively, for a sample containing 2% genetically modified soybeans. Application of this method depends on availability of appropriate reference materials for a specific food matrix. Only matrix-matched reference materials can be used for analysis of food or food fractions.

Abstract
Reducing the number of spermatozoa per artificial insemination (AI) dose and managing semen in ways to ensure greater quality at the same time represents current challenges with sperm processing in pig AI centers. Based on a multi-year comparative analysis of process steps in different pig AI centers, and complementary experimental studies under standardized laboratory conditions, current process standards for the preservation of boar semen have been updated and new ones developed. Currently, these standards represent an integral part of the quality assurance of 29 European pig AI centers in ten different organizations in Germany, Switzerland and Austria. Improvement of hygiene management and guidelines for prudent use of antibiotics have become key issues. Furthermore, new quality control tools have been implemented in the processing and transport of boar semen: e.g. refractometry as an easy-to-use tool to estimate extender osmolarity and 'mobile sensing' apps for continuous monitoring of various environmental parameters. Moreover, based on a series of experiments under laboratory and field conditions, guidelines for optimizing the dilution process, and time and temperature management during boar semen processing, have been developed and implemented. Similarly, recommendations for the handling of semen doses during storage have been renewed. Over the years, the efficiency of the quality assurance system has been reflected by a decrease of bacterial contamination and a concomitant increase in the quality of semen doses. In conclusion, science-based quality assurance is an effective way to improve the production performance in pig AI centers, resulting in high quality and economically-priced semen for pig producers. Increasing knowledge of sperm physiology together with computational and technical innovations will continue to develop and modify quality assurance concepts in the future.

Abstract
In this study a prognosis model is developed that predicts sperm quality characteristics based on external factors such as barn climate conditions, seasonality, semen collection frequency, age and breed of artificial insemination (AI) boars. For this a k-fold cross validation framework is used to test the prediction accuracy of a wide range of regression models that are based on different functional forms (linear, log-linear) and estimation techniques (ordinary least squares, seemingly unrelated regression, two-stage least squares estimation and three-stage least squares estimation). The dataset includes 241 boars from three barns within one boar stud located in Southern Germany, consisting of 7455 ejaculates collected during one year. The winner model predicts sperm motility with little error (Mean Absolute Percentage Error (MAPE): 4.35%), but is of limited use to predict sperm output (MAPE: 23.92%) and especially morphologically abnormal spermatozoa (MAPE: 44.67%). An estimation of marginal effects shows, that once confounding variables are controlled for, the considered barn climate variables do not have a measurable effect on sperm quality. Other factors have a more significant effect on sperm quality, like morphology-motility linkages, sperm concentration, interval between semen collections and to a lesser extent age and breed of the AI boar.

Abstract
Liquid preservation of the cold-sensitive boar sperm at a lesser temperature than the standard 17 °C would reduce bacterial growth and minimize the use of antibiotics. There was assessment, therefore, of the capacity of individual fatty acids bound to fatty acid free BSA to improve sperm survival at 6 °C because oxidative stress and lipid degradation are prominent detrimental factors. Different effects of the fatty acids were observed. Supplementation with naturally occurring fatty acids (linolenic, linoleic, oleic, palmitoleic acid), which may become metabolically incorporated into sperm lipids, increased the number of motile and progressively motile sperm after 2 days of storage during a thermo-resistance test (5 h at 38 °C) to that of control samples preserved at 17 °C in pure Beltsville Thawing Solution. With the exception of linolenic acid, all naturally occurring fatty acids enhanced the number of sperm with active mitochondria after 3 days of storage. Palmitoleic acid was the most effective supplement with effects already present when sperm were re-warmed for 30 min after 2 and 7 days of storage. The non-endogenous, non-integrated timnodonic acid (20:5) had no effect on sperm variables. Because the application of individual fatty acids attached to BSA had differing effects in preserving boar sperm at 6 °C, the use of combinations of fatty acids could be more efficacious than with use of natural lipid supplements for low temperature preservation of sperm.

Abstract
Recent reports indicate that stimulation of liquid-stored boar semen with red LED-based light improves sperm quality and reproductive performance in sow herds. So far, in vitro data after LED stimulation of whole semen doses are lacking. In this study, the effect of LED light exposure on the in vitro quality of boar spermatozoa after storage and thermic incubation was examined. Boar semen doses were stored at 17°C (n = 10) or 5°C (n = 6) in Beltsville Thawing Solution extender and then exposed to red LED light using a commercial photo chamber. During a subsequent long-term incubation at 38°C, neither sperm kinematic parameters nor mitochondria function or membrane integrity differed between control and treated samples (p > .05). It is concluded that stimulation of semen doses in the LED-photo chamber does not improve quality of thermically stressed boar sperm in vitro. Other than the sperm traits tested here might be involved in the previously reported improvement of in vivo fertility.

Abstract
The processing of ejaculates is a fundamental step for the fertilizing capacity of boar spermatozoa. The aim of the present study was to identify factors that affect quality of boar semen doses. The production process during 1 day of semen processing in 26 European boar studs was monitored. In each boar stud, nine to 19 randomly selected ejaculates from 372 Pietrain boars were analyzed for sperm motility, acrosome and plasma membrane integrity, mitochondrial activity and thermo-resistance (TRT). Each ejaculate was monitored for production time and temperature for each step in semen processing using the special programmed software SEQU (version 1.7, Minitüb, Tiefenbach, Germany). The dilution of ejaculates with a short-term extender was completed in one step in 10 AI centers (n = 135 ejaculates), in two steps in 11 AI centers (n = 158 ejaculates) and in three steps in five AI centers (n = 79 ejaculates). Results indicated there was a greater semen quality with one-step isothermal dilution compared with the multi-step dilution of AI semen doses (total motility TRT d7: 71.1 ± 19.2%, 64.6 ± 20.0%, 47.1 ± 27.1%; one-step compared with two-step compared with the three-step dilution; P < .05). There was a marked advantage when using the one-step isothermal dilution regarding time management, preservation suitability, stability and stress resistance. One-step dilution caused significant lower holding times of raw ejaculates and reduced the possible risk of making mistakes due to a lower number of processing steps. These results lead to refined recommendations for boar semen processing.

Abstract
ZusammenfassungPatienten mit Atherothrombose erhalten prophylaktisch ASS und/oder Clopidogrel zur Hemmung der Plättchenaggregation. Es wurde untersucht, ob ein aggregometrisches Verfahren den Effekt aggregationshemmender Substanzen (ASS 30, 50, 100, 300 mg/d, Clopidogrel 75 mg/d oder ASS 100 + Clopidogrel 75 mg/d) abbilden kann. Ein modifizierter Plättchenaggregationstest diente der Bestimmung der maximalen Aggregation nach Induktion mit ADP, Kollagen, Adrenalin und Arachidonsäure. Aus Werten eines gesunden Kollektivs wurden Referenzwerte abgeleitet und ein einfaches System zur Detektion inadäquater Plättchenhemmung entwickelt. Im Vergleich zur Kontrollgruppe zeigte sich eine signifikante Hemmung der maximalen Aggregation mit allen Induktoren bei Patienten unter ASS und der Kombination ASS + Clopidogrel. Bei Patienten unter Clopidogrel fand sich eine Hemmung der Aggregation nach Induktion mit ADP, Kollagen und Arachidonsäure. Unter 100 mg ASS/d trat eine ungenügende Hemmung bei 27%, unter 75 mg Clopidogrel/d bei 26% und unter der Kombinationstherapie bei 7% der Patienten auf. Die Ergebnisse zeigen, dass bei vielen Patienten mit arteriellen Thrombosen eine inadäquate Plättchenhemmung vorliegt.

Abstract
The subject of this article is the anatomy of the respiratory tract with an emphasis on the larynx. A differentiation is made between the upper and lower airways according to topographical and functional aspects, the limits of which are marked by the lower section of the larynx. The focus is on the anatomy of the structures involved, which are relevant for emergency medicine.

Abstract
AIM To compare image quality and evaluate its clinical importance in common temporal bone pathologies of a pTX-SPACE (parallel transmit [pTX] three-dimensional turbo spin-echo with variable flip angle [SPACE]) magnetic resonance imaging (MRI) sequence improved for spatial resolution to a standard-SPACE sequence exhibiting the same scan time at 3 T. MATERIALS AND METHODS Thirty-four patients were examined using a standard-SPACE and resolution improved pTX-SPACE sequence at 3 T MRI. The signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and image quality were assessed. Diseases investigated were vestibular schwannoma (VS), intralabyrinthine schwannoma (ILS), inner ear malformations, labyrinthitis, temporal bone fractures, and situation after VS resection. RESULTS Edge definition, intratumoural pattern, discrimination of VS from the modiolus and edge definition of ILS, separability from the spiral lamina, and detectability within cochlear turns were improved on the pTX-SPACE sequence. Detectability of malformations, post-traumatic changes, and discrimination of the cochlear and facial nerve after VS resection was improved on the pTX-SPACE sequence. In labyrinthitis, pTX-SPACE was not superior to standard-SPACE. The SNR and CNR were significantly reduced for pTX-SPACE. CONCLUSIONS pTX-SPACE significantly improves the detectability of temporal bone diseases, in particular, VS, ILS, and post-VS resection.
