Abstract
A novel Horizontal model is presented for multitrait analysis of longitudinal traits through random regression analysis combined with single recorded traits. Weekly ADFI on test for Danish Duroc, Landrace, and Yorkshire boars were available from the national test station and were collected from 30 to 100 kg BW. Single recorded production traits of ADG from birth to 30 kg BW (ADG30), ADG from 30 to 100 kg BW (ADG100), and lean meat percentage (LMP) were available from breeding herds or the national test station. The Horizontal model combined random regression analysis of feed intake (FI) with single recorded traits of ADG100, LMP, and ADG30. In the Horizontal model, the FI data were horizontally structured with FI on each week as a "trait." The additive genetic and litter effects were modeled to be common across different FI records by reducing the rank of the covariance matrices using second- and first-order Legendre polynomials of age on test, respectively. The fixed effect and random residual variance were estimated for each weekly FI trait. Residual feed intake (RFI) was derived from the conditional distribution of FI given the breeding values of ADG100 and LMP. The heritability of FI varied by week on test in Duroc (0.12 to 0.19), Landrace (0.13 to 0.22), and Yorkshire (0.21 to 0.23). The heritability of RFI was lowest and highest in wk 6 (0.03) and 10 (0.10), respectively, in Duroc and wk 7 (0.04 and 0.02) and 1 (0.09 and 0.20), respectively, in Landrace and Yorkshire. The proportion of FI genetic variance explained by RFI ranged from 20 to 75% in Duroc, from 19 to 75% in Landrace, and from 11 to 91% in Yorkshire. Average daily gain from 30 to 100 kg BW and ADG30 heritabilities were moderate in Duroc (0.24 and 0.22, respectively), Landrace (0.34 and 0.25, respectively), and Yorkshire (0.34 and 0.22, respectively). Lean meat percentage heritability was moderate in Duroc (0.37) and large in Landrace (0.62) and Yorkshire (0.60). The genetic correlation of FI with ADG100 increased by week on test followed by a 32% decrease from wk 7 in Duroc and a 7% decrease in dam line breeds. Defining RFI as genetically independent of production traits leads to consistent and easy interpretable breeding values. The genetic parameters of traits in the feed efficiency complex and their dynamics over the test period showed breed differences that could be related to the fatness and growth potential of the breeds. The Horizontal model can be used to simultaneously analyze repeated and single recorded traits through proper modeling of the environmental variances and covariances.

Abstract
Assessment of swallowing musculature using motor evoked potentials (MEPs) can be used to evaluate neural pathways. However, recording of the swallowing musculature is often invasive, uncomfortable and unrealistic in normal clinical practice. To investigate the possibility of using the suprahyoid muscle complex (SMC) using surface electromyography (sEMG) to assess changes to neural pathways by determining the reliability of measurements in healthy participants over days. Seventeen healthy participants were recruited. Measurements were performed twice with one week between sessions. Single-pulse (at 120% and 140% of the resting motor threshold (rMT)) and paired-pulse (2 ms and 15 ms paired pulse) transcranial magnetic stimulation (TMS) were used to elicit MEPs in the SMC which were recorded using sEMG. ≈50% of participants (range: 42-58%; depending on stimulus type/intensity) had significantly different MEP values between day 1 and day 2 for single-pulse and paired-pulse TMS. A large stimulus artefact resulted in MEP responses that could not be assessed in four participants. The assessment of the SMC using sEMG following TMS was poorly reliable for ≈50% of participants. Although using sEMG to assess swallowing musculature function is easier to perform clinically and more comfortable to patients than invasive measures, as the measurement of muscle activity using TMS is unreliable, the use of sEMG for this muscle group is not recommended and requires further research and development.

Abstract
Recent studies have characterized the extensive somatic alterations that arise during cancer. However, the somatic evolution of a tumor may be significantly affected by inherited polymorphisms carried in the germline. Here, we analyze genomic data for 5,954 tumors to reveal and systematically validate 412 genetic interactions between germline polymorphisms and major somatic events, including tumor formation in specific tissues and alteration of specific cancer genes. Among germline-somatic interactions, we found germline variants in RBFOX1 that increased incidence of SF3B1 somatic mutation by 8-fold via functional alterations in RNA splicing. Similarly, 19p13.3 variants were associated with a 4-fold increased likelihood of somatic mutations in PTEN. In support of this association, we found that PTEN knockdown sensitizes the MTOR pathway to high expression of the 19p13.3 gene GNA11 Finally, we observed that stratifying patients by germline polymorphisms exposed distinct somatic mutation landscapes, implicating new cancer genes. This study creates a validated resource of inherited variants that govern where and how cancer develops, opening avenues for prevention research.Significance: This study systematically identifies germline variants that directly affect tumor evolution, either by dramatically increasing alteration frequency of specific cancer genes or by influencing the site where a tumor develops.

Abstract
Objective Skeletal muscle is an important secretory organ, producing and releasing numerous myokines, which may be involved in mediating beneficial health effects of physical activity. More than 100 myokines have been identified by different proteomics approaches, but these techniques may not detect all myokines. We used mRNA sequencing as an untargeted approach to study gene expression of secreted proteins in skeletal muscle upon acute as well as long-term exercise. Methods Twenty-six middle-aged, sedentary men underwent combined endurance and strength training for 12 weeks. Skeletal muscle biopsies from m. vastus lateralis and blood samples were taken before and after an acute bicycle test, performed at baseline as well as after 12 weeks of training intervention. We identified transcripts encoding secretory proteins that were changed more than 1.5-fold in muscle after exercise. Secretory proteins were defined based on either curated UniProt annotations or predictions made by multiple bioinformatics methods. Results This approach led to the identification of 161 candidate secretory transcripts that were up-regulated after acute exercise and 99 that where increased after 12 weeks exercise training. Furthermore, 92 secretory transcripts were decreased after acute and/or long-term physical activity. From these responsive transcripts, we selected 17 candidate myokines sensitive to short- and/or long-term exercise that have not been described as myokines before. The expression of these transcripts was confirmed in primary human skeletal muscle cells during in vitro differentiation and electrical pulse stimulation (EPS). One of the candidates we identified was macrophage colony-stimulating factor-1 (CSF1), which influences macrophage homeostasis. CSF1 mRNA increased in skeletal muscle after acute and long-term exercise, which was accompanied by a rise in circulating CSF1 protein. In cultured muscle cells, EPS promoted a significant increase in the expression and secretion of CSF1. Conclusion We identified 17 new, exercise-responsive transcripts encoding secretory proteins. We further identified CSF1 as a novel myokine, which is secreted from cultured muscle cells and up-regulated in muscle and plasma after acute exercise. Numerous transcripts were identified that were regulated in human skeletal muscle after acute and/or long-term exercise. These transcripts encode potential myokines, which may play key roles in local and systemic adaptations to exercise. CSF1 was identified as a novel myokine. CSF1 was increased after acute exercise, and secreted from cultured human myotubes in response to EPS.

Abstract
First-year students often become discouraged during introductory biology courses when repeated attempts to understand concepts nevertheless result in poor test scores. This challenge is exacerbated by traditional course structures that impose premature judgments on students' achievements. Repeated testing has been shown to benefit student ability to recognize and recall information, but an effective means to similarly facilitate skill with higher-order problems in introductory courses is needed. Here, we show that an innovative format that uses a creative grading scheme together with weekly formative midterm exams produced significant gains in student success with difficult items requiring analysis and interpretation. This format is designed to promote tenacity and avoid discouragement by providing multiple opportunities to attempt demanding problems on exams, detailed immediate feedback, and strong incentives to retain hope and improve. Analysis of individual performance trajectories with heat maps reveals the diversity of learning patterns and provides rational means for advising students.

Abstract
Computed tomography of the chest was performed on 42 occasions as part of the diagnostic work-up in 26 homosexual men with, or suspected of the acquired immunodeficiency syndrome (AIDS). In 17 cases both the chest radiographs and the lung scans were abnormal, and bronchoscopy and/or lung biopsy established an etiologic diagnosis in the majority of these cases. In 9 cases CT of the lungs revealed unequivocal interstitial infiltration in the presence of a normal chest radiograph, and subsequently an etiologic agent was demonstrated in all these cases. In 9 cases, patients with symptoms indicative of pulmonary infection had both a normal chest radiograph and a normal lung scan, and in none of these cases did the clinical course or additional diagnostic procedures indicate the presence of current opportunistic lung infection. CT of the lungs seems to identify accurately those patients with severe HIV-related diseases in whom invasive diagnostic procedures such as bronchoalveolar lavage and/or lung biospy should be done.

Abstract
An emerging therapeutic strategy for cancer is to induce selective lethality in a tumor by exploiting interactions between its driving mutations and specific drug targets. Here we use a multi-species approach to develop a resource of synthetic lethal interactions relevant to cancer therapy. First, we screen in yeast ∼169,000 potential interactions among orthologs of human tumor suppressor genes (TSG) and genes encoding drug targets across multiple genotoxic environments. Guided by the strongest signal, we evaluate thousands of TSG-drug combinations in HeLa cells, resulting in networks of conserved synthetic lethal interactions. Analysis of these networks reveals that interaction stability across environments and shared gene function increase the likelihood of observing an interaction in human cancer cells. Using these rules, we prioritize ∼10(5) human TSG-drug combinations for future follow-up. We validate interactions based on cell and/or patient survival, including topoisomerases with RAD17 and checkpoint kinases with BLM.

Abstract
Abstract
An emerging therapeutic strategy for cancer is to induce selective lethality in a tumor by exploiting interactions between its driving mutations and specific drug targets. Here, we develop a resource of synthetic-lethal interactions between genes mutated in cancer, including many tumor suppressor genes (TSG), and selective chemical inhibitors including many FDA-approved drugs, using an integrative multi-species approach. Whereas, targeting oncogenes with either chemical inhibitors or therapeutic antibodies has proven to be highly effective for cancer therapy, it is not currently feasible to restore the function of mutated or deleted TSGs in the clinical setting. Rather than targeting a TSG directly, it is possible to exploit a “synthetic lethal” genetic interactions between the TSG and another gene, such that simultaneous disruption of both gene functions causes rapid and selective cell death. For example, cells deficient for BRCA1 have a reduced capacity for repairing double-stranded DNA breaks and are especially vulnerable to further perturbations in alternate DNA repair pathways. Oliparib, an FDA-approved drug, exploits this principle by targeting a component of the base excision repair pathway, PARP1, thus causing selective cell death in BRCA1-/- or BRCA2 -/- cells.
Recent efforts to map synthetic-lethal interactions in cancer typically fall into one of several categories. First, populations of tumor genomes may be analyzed statistically to detect pairs of genes that are seldom co-mutated in the same tumor, with one interpretation being that loss-of-function of both genes is synthetically lethal. While promising, such approaches are under-powered to test many relevant interactions, due to the already low frequency of mutation for most TSGs and the quadratic number of gene pairs that must be tested for co-mutation. Second, synthetic-lethal interactions may be mapped by directed combinatorial disruptions in human cell lines, using pairwise RNAi knockdowns, RNAi or drug treatments in cell lines with TSG loss-of-function or, conceivably in the near future, the CRISPR-Cas9 system. While such directed approaches can test relevant interactions in an unbiased manner, the largest screens performed to-date (∼10,000 gene pairs) still fall quite short of the required throughput to interrogate the potential interaction space of millions of human gene pairs involving a TSG.
A complementary strategy for mapping synthetic lethal interactions in cancer is to leverage conservation with genetic interactions first identified in model species. In the yeasts S. cerevisiae and S. pombe, techniques such as synthetic genetic arrays (SGA) and Pombe Epistasis Mapper (PEM) enable genetic interactions to be measured in an unbiased and high-throughput manner, with minimal off-target effects since the genes are disrupted by complete and specific knockout of the open reading frame. Such interactions are numerous and found to be significantly conserved across species, especially for the core conserved pathways in which TSGs typically operate such as the cell cycle, genome maintenance and metabolic growth. Many TSGs important for human cancer were first identified and studied in yeast, which also provides an accessible model system in which to study mechanism of action for effects first observed in humans. Nonetheless, it is unclear whether and to what extent synthetic lethal interactions observed for core conserved processes can be ultimately translated for clinical application. Multiple factors have been postulated to influence whether an interaction will be translatable, including genetic, epigenetic, and environmental context as well as the strength, redundancy, and network topology of the interaction. To study such factors, however, would require a large cross-species dataset of genetic interactions relevant to cancer genes and functions.
Here, we generate a comprehensive multi-species synthetic lethal network as a resource for the study of cancer and the design of targeted therapy. Leveraging the throughput and precise gene disruption of SGA technology, we experimentally test ∼78,000 potential interactions to generate a network that includes quantitative tests for interaction among all yeast orthologs of human TSGs and genes that are currently targetable by selective inhibitors (“druggable” targets or DT). Guided by these data, we target 2,352 TSG-drug combinations in human HeLa cells, resulting in a validated network of 172 “deeply conserved” interactions, called CoCaNet (Conserved Cancer Network). Having created this resource of conserved synthetic lethal interactions we explored three possible applications. First we demonstrate that synthetic lethal relationships in the conserved network are strongly predictive of cell survival in orthogonal survival assays and in alternate cell lines. We validated synthetic lethal interactions between the TSG RAD17 and all five synthetic lethal partners in CoCaNet (CHEK1, CHEK2, TOP2, TOP3A, CSNK1G1) in clonogenic assays using HeLa cells. For the TSG XRCC3 five of seven synthetic lethal partners (HDAC1, HDAC2, HDAC6, IMPDH1, RABGGTB) were confirmed in clonogenic assay in LN428 glioblastoma cells.
Second, we examined the clinical relevance of these synthetic lethal networks. Using gene expression and clinical survival data of breast cancer patients from the METABRIC database (Curtis et al., Nature 2012) we tested our hypothesis that co-under expression of genes in CoCaNet would reduce the fitness of a tumor and associate with better clinical outcome. As expected overall survival was 8.6 years for those patients in the top 90th percentile of synthetic lethal interactions vs. 7.3 years for the 10th percentile (log-rank p < 0.0005). We also assessed the extent to which CoCaNet might serve as a source of potentially relevant interactions for a broad population of cancer patients. CoCaNet includes a total of 59 unique TSGs and provides an average of ∼3 conserved interactions for each. Based on analysis of 7,394 cases profiled by TCGA across 22 tumor types, we found that at least one of these TSGs is either mutated or homozygously deleted in approximately 42% of patients, with 19% of patients having alterations to two or more of these TSGs. One specific example of how this network could be used for precision medicine is seen with ATM. TOP3A, commonly targeted by irinotecan in metastatic colorectal cancer (mCRC), in which ATM is mutated in 18% of tumors, was found to be a synthetic-sick/lethal interaction partner with ATM. These synthetic lethal data suggest that FOLFIRI (5-flourouracil plus irinotecan) may be the preferred initial regimen in ATM mutant mCRC. Although these finding would clearly need to be validated prior to influencing a clinical decision, the case of ATM-TOP3A is just one example of how the CoCaNet could be used to derive potentially clinically actionable information from a tumor genome.
Third, we use the overlapping yeast and human synthetic lethal networks to learn the ‘rules’ that govern whether an interaction observed in yeast will be conserved in humans. We annotated each gene pair with multiple observations including whether we had observed interaction conservation with yeast, the degree to which the genes are co-expressed, whether the gene products are linked by a protein-protein interaction, and whether the genes are known to co-function in the same Gene Ontology biological process. Training on the overlapping yeast and human networks we integrated these multiple lines of evidence into a combined Log Likelihood Score classifier. Applying this classifier of cross-species conservation to the complete yeast network we are able to predict an expanded human network of over 11,000 prioritized synthetic sick or lethal interactions for pre-clinical and ultimately clinical exploration, each backed by data from budding yeast for investigating drug mode of action.

Abstract
Objective: To compare the postoperative discomfort and long-term outcome following standard stripping and atter long saphenous vein-saving surgery. Design: Prospective, randomized case-control study with patients serving as their own controls. Setting: Department of Surgery, County Hospital, Varberg, Sweden. Patients: Eighteen patients with bilateral primary varicose veins. Interventions: The patients were randomized prospectively to stripping or long saphenous vein-saving surgery. The leg causing most discomfort was operated on first. The other leg was operated on using the alternative method. Main outcome measures: Postoperative discomfort was assessed after an interview with the patient. Long-term outcome was determined by clinical assessment and Plethysmographic venous return time. Results: After 4 years the legs subjected to long saphenous vein-saving surgery yielded equal clinical results and had as great a prolongation of the plethysmographic venous return time as legs operated on using standard stripping. More patients reported greater discomfort following stripping than after vein-saving surgery. The saved long saphenous vein in all legs operated on was patent, compressible, non-sclerotic and free of intraluminal echoes. Conclusion: The long-term results of long saphenous vein-saving surgery are as good as standard stripping, provided that incompetent perforators are throughly mapped preoperatively and ligated at surgery. Long saphenous vein-saving surgery causes less subjective postoperative discomfort than standard stripping. The saved long saphenous vein can probably be used for future arterial reconstruction.

Abstract
Objective: To study the mechanisms by which haemodynamic function improves following long saphenous vein-saving surgery. Design: Cohort study. Patients: Twenty patients, 14 women and six men, with primary varicose veins. Interventions: Varicose vein surgery by the long saphenous vein-saving technique. Main outcome measures: Preoperative investigation by physical examination, strain-gauge plethysmography, phlebography and measurements of the long saphenous vein diameter at four different locations using high-resolution, real-time ultrasound. Three months following vein-saving surgery, the patients were reassessed with physical examination, strain-gauge plethysmography and measurements of the long saphenous vein diameter. Results: All patients but one showed excellent or good results following surgery. The preoperative diameter of the long saphenous vein was reduced by 40% at four different levels in the operated legs ( p<0.01). The venous return time of the same legs increased 2.4 times ( p<0.001). The decrease of the long saphenous vein diameter correlated positively with the increase in venous return time (t-50), ( r=0.50, p=0.04). Conclusion: The results suggest that the development of incompetent perforators is an early major event in the formation of primary varicose veins. The results also suggest that the long saphenous vein valvular incompetence in varicose veins is attributable to venous wall dilatation rather than degeneration of the valves. The results support the hypothesis that the improvement in haemodynamic function following long saphenous vein-saving surgery is due, at least partly, to a reduction of the long saphenous vein diameter, which in turn tends to restore valvular competence.

Abstract
Feral American mink populations (), derived from mink farms, are widespread in Europe. In this study we investigated genetic diversity and genetic differentiation between feral and farm mink using a panel of genetic markers (194 SNP) generated from RAD sequencing data. Sampling included a total of 211 individuals from 14 populations, 4 feral and 10 from farms, the latter including a total of 7 color types (Brown, Black, Mahogany, Sapphire, White, Pearl, and Silver). Our study revealed similar low levels of genetic diversity in both farm and feral mink. Results are consistent with small effective population size as a consequence of line selection in the farms and founder effects of a few escapees from the farms in feral populations. Moderately high genetic differentiation was found between farm and feral animals, suggesting a scenario in which wild populations were founded from farm escapes a few decades ago. Currently, escapes and gene flow are probably limited. Genetic differentiation was higher among farm color types than among farms, consistent with line selection using few individuals to create the lines. Finally, no indications of inbreeding were found in either farm or feral samples, with significant negative values found in most farm samples, showing farms are successful in avoiding inbreeding.

Abstract
AIM Some health benefits of exercise may be explained by an altered secretion of myokines. Because previous focus has been on upregulated myokines, we screened for downregulated myokines and identified myostatin. We studied the expression of myostatin in relation to exercise and dysglycaemia in skeletal muscle, adipose tissue and plasma. We further examined some effects of myostatin on energy metabolism in primary human muscle cells and Simpson-Golabi-Behmel syndrome (SGBS) adipocytes. METHODS Sedentary men with or without dysglycaemia underwent a 45-min acute bicycle test before and after 12 weeks of combined endurance and strength training. Blood samples and biopsies from m. vastus lateralis and adipose tissue were collected. RESULTS Myostatin mRNA expression was reduced in skeletal muscle after acute as well as long-term exercise and was even further downregulated by acute exercise on top of 12-week training. Furthermore, the expression of myostatin at baseline correlated negatively with insulin sensitivity. Myostatin expression in the adipose tissue increased after 12 weeks of training and correlated positively with insulin sensitivity markers. In cultured muscle cells but not in SGBS cells, myostatin promoted an insulin-independent increase in glucose uptake. Furthermore, muscle cells incubated with myostatin had an enhanced rate of glucose oxidation and lactate production. CONCLUSION Myostatin was differentially expressed in the muscle and adipose tissue in relation to physical activity and dysglycaemia. Recombinant myostatin increased the consumption of glucose in human skeletal muscle cells, suggesting a complex regulatory role of myostatin in skeletal muscle homeostasis.

Abstract
AIM Chitinase-3-like protein 1 (CHI3L1) is involved in tissue remodelling and inflammatory processes. Plasma levels are elevated in patients with insulin resistance and T2DM. We recently showed that CHI3L1 and its receptor protease-activated receptor 2 (PAR-2) are expressed in skeletal muscle. Activation of PAR-2 by CHI3L1 protects against TNF-α-induced inflammation and insulin resistance. However, the effect of exercise on CHI3L1 and PAR-2 signalling remains unknown. The aim of this work was to study the impact of exercise on CHI3L1 production and the effect of CHI3L1/PAR-2 signalling on skeletal muscle growth and repair. METHODS Three human exercise studies were used to measure CHI3L1 plasma levels (n = 32). In addition, muscle and adipose tissue CHI3L1 mRNA expression was measured in response to acute and long-term exercise (n = 24). Primary human skeletal muscle cells were differentiated in vitro, and electrical pulse stimulation was applied. In addition, myoblasts were incubated with CHI3L1 protein and activation of MAP kinase signalling as well as proliferation was measured. RESULTS Circulating CHI3L1 levels and muscle CHI3L1 mRNA were increased after acute exercise. In addition, CHI3L1 mRNA expression as well as CHI3L1 secretion was enhanced in electrically stimulated cultured myotubes. Incubation of cultured human myoblasts with CHI3L1 protein leads to a strong activation of p44/42, p38 MAPK and Akt as well as enhanced myoblast proliferation. CONCLUSION Our findings suggest that CHI3L1 is induced by acute exercise and that CHI3L1/PAR-2 signalling activates myocyte proliferation, which is important for restructuring of skeletal muscle in the response to exercise training.

Abstract
The study investigated genetic architecture and predictive ability using genomic annotation of residual feed intake (RFI) and its component traits (daily feed intake [DFI], ADG, and back fat [BF]). A total of 1,272 Duroc pigs had both genotypic and phenotypic records, and the records were split into a training (968 pigs) and a validation dataset (304 pigs) by assigning records as before and after January 1, 2012, respectively. SNP were annotated by 14 different classes using Ensembl variant effect prediction. Predictive accuracy and prediction bias were calculated using Bayesian Power LASSO, Bayesian A, B, and Cπ, and genomic BLUP (GBLUP) methods. Predictive accuracy ranged from 0.508 to 0.531, 0.506 to 0.532, 0.276 to 0.357, and 0.308 to 0.362 for DFI, RFI, ADG, and BF, respectively. BayesCπ100.1 increased accuracy slightly compared to the GBLUP model and other methods. The contribution per SNP to total genomic variance was similar among annotated classes across different traits. Predictive performance of SNP classes did not significantly differ from randomized SNP groups. Genomic prediction has accuracy comparable to observed phenotype, and use of genomic prediction can be cost effective by replacing feed intake measurement. Genomic annotation had less impact on predictive accuracy traits considered here but may be different for other traits. It is the first study to provide useful insights into biological classes of SNP driving the whole genomic prediction for complex traits in pigs.

Abstract
There is limited research on the physiological effects of caffeine (CAF) ingestion on exercise performance during acute hypoxia. The aim of the present study was therefore to test the effect of placebo (PLA) and CAF (4.5 mg/kg) on double poling (DP) performance during acute hypoxia. Thirteen male subelite cross-country skiers (V̇o2max 72.6 ± 5.68 ml·kg−1·min−1) were included. Performance was assessed as 1) an 8-km cross-country DP time-trial (C-PT), and 2) time until task failure at a set workload equal to ∼90% of DP V̇o2max. Testing was carried out in a hypobaric chamber, at 800 mbar (Pio2: ∼125 mmHg) corresponding to ∼2,000 m above sea level in a randomized double-blinded, placebo-controlled, cross-over design. CAF improved time to task failure from 6.10 ± 1.40 to 7.22 ± 1.30 min ( P < 0.05) and velocity the first 4 km ( P < 0.05) but not overall time usage for the 8-km C-PT. During submaximal exercise subjects reported lower pain in arms and rate of perceived exertion (RPE) following CAF ingestion. Throughout C-PTs similar RPE and pain was shown between treatments. However, higher heart rate was observed during the CAF 8 km (187 ± 7 vs. 185 ± 7; P < 0.05) and 90% C-PT (185 ± 7 vs. 181 ± 9) associated with increased ventilation, blood lactate, glucose, adrenaline, decreased pH, and bicarbonate. The present study demonstrates for the first time that CAF ingestion improves DP time to task failure although not consistently time trial performance during acute exposure to altitude. Mechanisms underpinning improvements seem related to reduced pain RPE and increased heart rate during CAF C-PTs.

Abstract
Including genotyped females in a reference population (RP) is an obvious way to increase the RP in genomic selection, especially for dairy breeds of limited population size. However, the incorporation of these females must be conducted cautiously because of the potential preferential treatment of the genotyped cows and lower reliabilities of phenotypes compared with the proven pseudo-phenotypes of bulls. Breeding organizations in Denmark, Finland, and Sweden have implemented a female-genotyping project with the possibility of genotyping entire herds using the low-density (LD) chip. In the present study, 5 scenarios for building an RP were investigated in the Nordic Jersey population: (1) bulls only, (2) bulls with females from the LD project, (3) bulls with females from the LD project plus non-LD project females genotyped before their first calving, (4) bulls with females from the LD project plus non-LD project females genotyped after their first calving, and (5) bulls with all genotyped females. The genomically enhanced breeding value (GEBV) was predicted for 8 traits in the Nordic total merit index through a genomic BLUP model using deregressed proof (DRP) as the response variable in all scenarios. In addition, (daughter) yield deviation and raw phenotypic data were studied as response variables for comparison with the DRP, using stature as a model trait. The validation population was formed using a cut-off birth year of 2005 based on the genotyped Nordic Jersey bulls with DRP. The average increment in reliability of the GEBV across the 8 traits investigated was 1.9 to 4.5 percentage points compared with using only bulls in the RP (scenario 1). The addition of all the genotyped females to the RP resulted in the highest gain in reliability (scenario 5), followed by scenario 3, scenario 2, and scenario 4. All scenarios led to inflated GEBV because the regression coefficients are less than 1. However, scenario 2 and scenario 3 led to less bias of genomic predictions than scenario 5, with regression coefficients showing less deviation from scenario 1. For the study on stature, the daughter yield deviation/daughter yield deviation performed slightly better than the DRP as the response variable in the genomic BLUP (GBLUP) model. Therefore, adding unselected females in the RP could significantly improve the reliabilities and tended to reduce the prediction bias compared with adding selectively genotyped females. Although the DRP has performed robustly so far, the use of raw data is recommended with a single-step model as an optimal solution for future genomic evaluations.

Abstract
Crosses between different mink lines from 3 Danish mink farms that use different breeding strategies were studied to estimate heterosis and variance components for litter size. The study was designed to analyze crosses between lines of the same color type, between different color types, and between animals originating from different farms. Effect of heterosis, color type, and variance components were estimated using Average information REML (AI-REML) algorithm implemented in the DMU package for analyzing multivariate mixed models. Females from 7 generations that gave birth to at least 1 offspring were analyzed and the effects of parity and production year were included in the analyses. Genetic trend and the proportions of the total variance explained by the effects of additive genetics (h2), common environment (due to repeated litters from the same female; c2), and dam of the female (granddame of the born litter; d2) were estimated. The results showed that mink of the Black color type potentially produced smaller litters compared to mink of the other studied color types. We found significant general maternal effect of heterosis for litter size. Analyses of specific heterosis showed a significant positive effect of crossing between lines of the same color type. Estimates of variance components revealed h2 levels for farm A, B, and C of 0.15, 0.06, and 0.09, respectively; thus litter size could be selected for in the future. The effect of common environment on litter size was also considerable, with c2 values of 0.005, 0.11, and 0.15 at farms A, B, and C, respectively. In conclusion, we recommend genetic selection as a means of increasing litter size in farmed mink.

Abstract
Es wird die Hämin-Heterotrophie einer streptomycinresistenten Variante von M. pyog. var. aureus SG 511 nachgewiesen. Sie drückt sich aus: 1. in der Wuchsunfähigkeit der Variante auf häminfreiem Nähragar und in häminfreier stark belüfteter Nährlösung; 2. in dem Unvermögen, eisenhaltige Atmungsfermente und Katalase zu synthetisieren, unter Bedingungen, die trotz des Fehlens dieser Fermente Wachstum gestatten. Es wird gezeigt, daß Atmung und Katalasebildung nur in häminhaltigen Nährböden (Häminkonzentration bis 3×10-7) möglich ist.

Abstract
Es wird für eine häminheterotrophe, streptomycinresistente Variante von Mikrococcus pyogenes var. aureus SG 511 nachgewiesen, daβ sie in häminfreien Nährböden den Proteinanteil der Katalase und zumindest eines Teiles des Cytochromsystems bildet. Nach Zusatz von Hämin zu den ruhenden Bakterien wird der letzte Schritt der Synthese zum Holoferment vollzogen. Der Nachweis wird teils durch quantitative Bestimmung der fermentativen Leistungen der ruhenden Bakterien, teils durch spektroskopische Untersuchungen geführt. Auf die Möglichkeit einer spezifischen Hemmung dieses letzten Syntheseschrittes wird hingewiesen.

Abstract
Es wird bei einem Mikrokokkenstamm und seiner häminheterotrophen Variante ein O2übertragendes Ferment nachgewiesen, das sicher nicht mit Warburgs klassischem Ferment identisch ist. Mittels verschiedener Methoden wird der Nachweis erbracht, daß seine prosthetische Gruppe Protohämin ist.
