Abstract
Background and aim: Medication errors lead to preventable risks. Preventing strategies such as e-prescribing, clinical pharmacists and medication reconciliation have been implemented in recent years. However, information on long-term medication error rates in routine procedures is missing. Investigations: We aimed to identify predefined medication errors in ten wards of a university hospital where e-prescribing, clinical pharmacists and medication reconciliation have been partially implemented. Patient files were reviewed and routine processes were monitored for drug prescription errors (missing, unclear, outdated information), administration errors (wrong dispensed drugs) and drug handling errors (no light-, moisture-protection, wrong splitting, no separation of drugs, which ought to be taken by an empty stomach). Results: We analyzed 959 prescriptions with 933 solid peroral drugs for 182 patients (98 female, median age 66.5 years [Q25-Q75: 56-78 years]; the median number of drugs was 5 [Q25-Q75: 3-7]). The most frequent prescription error was a not specified drug form (91.1%). The most common administration error was a not adequately provided release dose formulation (72.7%). The lack of light protection for observed photosensitive drugs was the most frequent drug handling error (100%). We found a significantly higher amount of complete drug prescriptions with one of the implemented measurements e-prescribing, medication reconciliation and clinical pharmacists (Fisher's exact test two tailed, each p<0.001; CI 95%). Drug administration errors and drug handling errors were not significantly improved. Among the most frequently involved drug were drugs for acid-related disorders, immunosuppressant, and antineoplastic drugs. Conclusions: In the nearly 1,000 prescriptions and drugs analyzed, medication errors were still common. Various preventive strategies had been implemented in recent years, positively influencing the predefined errors rates.

Abstract
Physiologically relevant drought stress is difficult to apply consistently, and the heterogeneity in experimental design, growth conditions, and sampling schemes make it challenging to compare water deficit studies in plants. Here, we re-analyzed hundreds of drought gene expression experiments across diverse model and crop species and quantified the variability across studies. We found that drought studies are surprisingly uncomparable, even when accounting for differences in genotype, environment, drought severity, and method of drying. Many studies, including most Arabidopsis work, lack high-quality phenotypic and physiological datasets to accompany gene expression, making it impossible to assess the severity or in some cases the occurrence of water deficit stress events. From these datasets, we developed supervised learning classifiers that can accurately predict if RNA-seq samples have experienced a physiologically relevant drought stress, and suggest this can be used as a quality control for future studies. Together, our analyses highlight the need for more community standardization, and the importance of paired physiology data to quantify stress severity for reproducibility and future data analyses.

Abstract
Obesity promotes diverse pathologies, including atherosclerosis and dementia, which frequently involve vascular defects and endothelial cell (EC) dysfunction. Each organ has distinct EC subtypes, but whether ECs are differentially affected by obesity is unknown. Here we use single-cell RNA sequencing to analyze transcriptomes of ~375,000 ECs from seven organs in male mice at progressive stages of obesity to identify organ-specific vulnerabilities. We find that obesity deregulates gene expression networks, including lipid handling, metabolic pathways and AP1 transcription factor and inflammatory signaling, in an organ- and EC-subtype-specific manner. The transcriptomic aberrations worsen with sustained obesity and are only partially mitigated by dietary intervention and weight loss. For example, dietary intervention substantially attenuates dysregulation of liver, but not kidney, EC transcriptomes. Through integration with human genome-wide association study data, we further identify a subset of vascular disease risk genes that are induced by obesity. Our work catalogs the impact of obesity on the endothelium, constitutes a useful resource and reveals leads for investigation as potential therapeutic targets.

Abstract
OBJECTIVE Despite evidence for the prenatal onset of abnormal head growth in children with autism spectrum disorder (ASD), studies on fetal ultrasound data in ASD are limited and controversial. METHOD We conducted a longitudinal matched case-sibling-control study on prenatal ultrasound biometric measures of children with ASD, and 2 control groups: (1) their own typically developed sibling (TDS) and (2) typically developed population (TDP). The cohort comprised 528 children (72.7% male), 174 with ASD, 178 TDS, and 176 TDP. RESULTS During the second trimester, ASD and TDS fetuses had significantly smaller biparietal diameter (BPD) than TDP fetuses (adjusted odds ratio for the z score of BPD [aORzBPD] = 0.685, 95% CI = 0.527-0.890, and aORzBPD = 0.587, 95% CI = 0.459-0.751, respectively). However, these differences became statistically indistinguishable in the third trimester. Interestingly, head biometric measures varied by sex, with male fetuses having larger heads than female fetuses within and across groups. A linear mixed-effect model assessing the effects of sex and group assignment on fetal longitudinal head growth indicated faster BPD growth in TDS versus both ASD and TDP in male fetuses (β = 0.084 and β = 0.100 respectively; p < .001) but not in female fetuses, suggesting an ASD-sex interaction in head growth during gestation. Finally, fetal head growth showed conflicting correlations with ASD severity in male and female children across different gestation periods, thus further supporting the sex effect on the association between fetal head growth and ASD. CONCLUSION Our findings suggest that abnormal fetal head growth is a familial trait of ASD, which is modulated by sex and is associated with the severity of the disorder. Thus, it could serve as an early biomarker for ASD.

Abstract
The behaviour regarding the fluid intake in adolescents and young adults is an important issue, since these data may provide information about the health consciousness of the next generation. Inappropriate daily beverages intake for a long period can have adverse effects on human health. Positive effects of maintenance of good hydration are known in the prevention of chronic diseases like urolithiasis, bladder or colon cancer, hypertension, obesity, or constipation. In the present study, we examine the various factors of beverage intake by university students. Data from 3020 students of the Czech and Slovak universities were collected in 2016–2018 to evaluate their daily fluid intake and the characteristics of beverage consumptions. We found that gender, country, frequency of daily water intake, nutrition literacy, and some other factors influence whether a student reports having a daily water intake of more than 1.5 litres. Our respondents have preferences for beverages, based on taste and health effects primarily, prices and availability were secondary. We present the suggestions for a more balanced beverage intake for the studied age group.

Abstract
BACKGROUND Pain is a common and burdensome complication in patients with acute stroke. We assessed the impact of impaired communication in stroke patients on pain assessment and treatment. METHODS We included 909 (507 male, mean age 71.8 years) patients admitted to our stroke unit from 01/2015 to 12/2015 in the analysis. Patients were assigned to four groups: able to communicate (AC), not able to communicate prior to index stroke (P-NAC), due to focal symptoms of index stroke (S-NAC), due to a reduced level of consciousness (C-NAC). Pain prevalence, documentation of pain and use of analgesics were evaluated. C-NAC patients were excluded from analyses regarding analgesic treatment due to relevant differences in patient characteristics. RESULTS 746 patients (82.1%) were classified as AC, 25 (2.8%) as P-NAC, 90 (9.9%) as S-NAC and 48 (5.3%) as C-NAC. Pain was documented on the Numeric Rating Scale and in form of free text by nurses and physicians. Nurses documented pain more frequently than physicians (p < 0.001). Pain prevalence was 47.0% (n.s. between groups). The use of analgesic medication increased from 48.7% in the AC group, to 76.0% in the P-NAC group, and 77.8% in the S-NAC group (p < 0.001). Opioid use was significantly more frequent in NAC patients (p < 0.001). The response to the treatment was poorly documented with significantly lowest rates in S-NAC patients (p < 0.001). CONCLUSIONS Our study suggests that post-stroke pain in patients with inability to communicate is not attended enough, not systematically assessed and therefore not sufficiently treated.

Abstract
High-throughput sequencing produces an extraordinary amount of genomic data that is organized into a number of high-dimension datasets. Accordingly, visualization of genomic data has become essential for quality control, exploration, and data interpretation. The Variant Call Format (VCF) is a text file format generated during the variant calling process that contains genomic information and locations of variants in a group of sequenced samples. The current workflow for visualization of genomic variant data from VCF files requires use of a combination of existing tools. Here, we describe VIVA (VIsualization of VAriants), a command line utility and Jupyter Notebook based tool for evaluating and sharing genomic data for variant analysis and quality control of sequencing experiments from VCF files. VIVA combines the functionality of existing tools into a single command to interactively evaluate and share genomic data, as well as create publication quality graphics.

Abstract
Lissencephaly comprises a spectrum of brain malformations due to impaired neuronal migration in the developing cerebral cortex. Classical lissencephaly is characterized by smooth cerebral surface and cortical thickening that result in seizures, severe neurological impairment and developmental delay. Mutations in the X-chromosomal gene DCX, encoding doublecortin, is the main cause of classical lissencephaly. Much of our knowledge about DCX-associated lissencephaly comes from post-mortem analyses of patient's brains, mainly since animal models with DCX mutations do not mimic the disease. In the absence of relevant animal models and patient brain specimens, we took advantage of induced pluripotent stem cell (iPSC) technology to model the disease. We established human iPSCs from two males with mutated DCX and classical lissencephaly including smooth brain and abnormal cortical morphology. The disease was recapitulated by differentiation of iPSC into neural cells followed by expression profiling and dissection of DCX-associated functions. Here we show that neural stem cells, with absent or reduced DCX protein expression, exhibit impaired migration, delayed differentiation and deficient neurite formation. Hence, the patient-derived iPSCs and neural stem cells provide a system to further unravel the functions of DCX in normal development and disease.

Abstract
We study quasi-ballistic electron transport in metallic (6, 0) carbon nanotubes (CNTs) of variable length in contact with Al, Cu, Pd, Pt, Ag, and Au electrodes by using the non-equilibrium Green's function formalism in combination with either density functional theory or self-consistent extended Hückel theory. We find good agreement between both. Visualizing the local device density of states of the systems gives a descriptive link between electronic structure and transport properties. In comparison with bare finite and infinite tubes, we show that the electronic structure of short metallic CNTs is strongly modified by the presence of the metallic electrodes, which leads to pronounced size effects in the conductance. The mean conductances and linear response currents allow a ranking of the metals regarding their ability to form low-Ohmic contacts with the nanotube: Ag < or approximately equel to Au < Cu <<Pt ≈Pd << Al. These findings are contrasted with similar trends in contact distance, binding energy, calculated work function of the metal surfaces, and various results from literature.

Abstract
BACKGROUND The GeparQuinto study showed that adding bevacizumab to 24 weeks of anthracycline-taxane-based neoadjuvant chemotherapy increases pathological complete response (pCR) rates overall and specifically in patients with triple-negative breast cancer (TNBC). No difference in pCR rate was observed for adding everolimus to paclitaxel in nonearly responding patients. Here, we present disease-free (DFS) and overall survival (OS) analyses. PATIENTS AND METHODS Patients (n = 1948) with HER2-negative tumors of a median tumor size of 4 cm were randomly assigned to neoadjuvant treatment with epirubicin/cyclophosphamide followed by docetaxel (EC-T) with or without eight infusions of bevacizumab every 3 weeks before surgery. Patients without clinical response to EC ± Bevacizumab were randomized to 12 weekly cycles paclitaxel with or without everolimus 5 mg/day. To detect a hazard ratio (HR) of 0.75 (α = 0.05, β = 0.8) 379 events had to be observed in the bevacizumab arms. RESULTS With a median follow-up of 3.8 years, 3-year DFS was 80.8% and 3-year OS was 89.7%. Outcome was not different for patients receiving bevacizumab (HR 1.03; P = 0.784 for DFS and HR 0.974; P = 0.842 for OS) compared with patients receiving chemotherapy alone. Patients with TNBC similarly showed no improvement in DFS (HR = 0.99; P = 0.941) and OS (HR = 1.02; P = 0.891) when treated with bevacizumab. No other predefined subgroup (HR+/HER2-; locally advanced (cT4 or cN3) or not; cT1-3 or cT4; pCR or not) showed a significant benefit. No difference in DFS (HR 0.997; P = 0.987) and OS (HR 1.11; P = 0.658) was observed for nonearly responding patients receiving paclitaxel with or without everolimus overall as well as in subgroups. CONCLUSIONS Long-term results, in opposite to the results of pCR, do not support the neoadjuvant use of bevacizumab in addition to an anthracycline-taxane-based chemotherapy or everolimus in addition to paclitaxel for nonearly responding patients.

Abstract
Trichoderma atroviride IMI 206040 synthesizes the coconut lactone 6-pentyl-α-pyrone (6-PAP) de novo and Aspergillus niger DSM 821 produces the rose-like flavour compound 2-phenylethanol (2-PE) from the precursor l-phenylalanine. Here, microparticles of different chemical composition and nominal particle diameter in the range 5-250 µm were added to shake-flask cultures of both fungi to investigate the particles' effect on product formation. Maximum 2-PE concentration increased by a factor of 1.3 to 1430 mg/l with the addition of 2% w/v talc (40 µm diameter). Maximum 6-PAP concentration increased by a factor of 2 to 40 mg/l with the addition of 2% w/v iron (II, III) oxide. The influence of ions leaching out of the particles was investigated by cultivating the fungi in leached particle medium. For the first time, the positive effect of the microparticle-enhanced cultivation (MPEC) technique on the microbial production of volatile metabolites, here flavour compounds from submerged fungal cultures, is demonstrated. The effect is strain- and particle-specific.

Abstract
AIM The aim of this study was to collect procedural and clinical data assessing safety and performance of the GORE® TIGRIS® Vascular Stent, a novel dual component stent, made of a nitinol wire frame combined with a fluoropolymer-interconnecting structure. METHODS This retrospective analysis included 32 consecutive patients (20 men, mean age 72.8 years) with 40 atherosclerotic femoropopliteal lesions (occlusions in 5%) who underwent angioplasty and implantation of a GORE® TIGRIS® Vascular Stent. The patients were scheduled for follow-up at 3, 6 and 12 months after stent implantation for Duplex ultrasound and assessment of Rutherford Becker class (RBC) and Ankle-Brachial Index (ABI) RESULTS: The mean implanted stent length was 62.3 mm (range 30-100 mm). Procedural success (residual stenosis <30%) was achieved in 100% of the lesions. At 6 months 2 restenosis in 2 patients were observed, resulting in a cumulative primary patency rate (±standard error) of 91.7±8.0%. Between baseline and 6 months the ABI increased from 0.65±0.18 to 0.96±0.12 (P<0.0001) and the median of RBC increased from 3 to 1.5 (P<0.0005). No stent thrombosis was found. CONCLUSION In this retrospective collection of patients all lesions could be successfully treated with this novel hybrid TIGRIS stent. These preliminary results show promising primary patency rates at 6 months. In addition, significant improvements were observed in symptom classification and hemodynamics.

Abstract
Photoluminescence lineshape properties of quasi-two-dimensional electron systems in setback δ-doped GaAs heterostructures are studied at liquid helium temperature. Contributions from the ground and the first excited two-dimensional subband are clearly observed. A simple fit to the lineshape including broadening demonstrates that there is an exponential low-energy tail associated with the ground subband. No such tail is observed for the first excited subband. The fit precisely reveals the subband bottom energies, the Fermi energy, the electron temperature and the recombination intensities. A self-consistent calculation of subband properties including the potential contribution of the setback δ-doping reproduces well the subband properties and the recombination intensities.

Abstract
We report a 51-year-old patient with severe haemophilia A developing a severe life-threatening anaphylactic reaction to recombinant factor VIII (rFVIII). Anaphylactic reactions are a rare but well-known side effect of FVIII products. The nature of these reactions could not be clarified as previous studies failed to demonstrate a specific IgE response. Here, we could prove a grade 3 anaphlyactic reaction as an IgE-mediated response to rFVIII for the first time by Western blotting.

Abstract
Single molecule wide field imaging is applied to study the diffusion in ultrathin liquid films on solid surfaces. The results show a broad distribution of diffusion coefficients. This is tentatively ascribed to an anisotropy of the diffusion coefficient perpendicular to the surface and a slow exchange of molecules between regions of different diffusion coefficients. We have evidence, that these changes as well as the slow motion perpendicular to the surface are related to the molecular layering of the liquid close to the surface.

Abstract
More than 40 Feshbach resonances in rubidium 87 are observed in the magnetic-field range between 0.5 and 1260 G for various spin mixtures in the lower hyperfine ground state. The Feshbach resonances are observed by monitoring the atom loss, and their positions are determined with an accuracy of 30 mG. In a detailed analysis, the resonances are identified and an improved set of model parameters for the rubidium interatomic potential is deduced. The elastic width of the broadest resonance at 1007 G is predicted to be significantly larger than the magnetic-field resolution of the apparatus. This demonstrates the potential for applications based on tuning the scattering length.

Abstract
OBJECTIVE Based on their on experience the authors express their opinion on routine detection and visualization of the NLR during radical surgery of the thyroid gland. They describe standard and alternative steps of surgery leading to protection of the recurrent nerve. MATERIAL AND METHODS The authors evaluated a group of 735 patients operated during the last thirty nine months which comprised 87% total thyroidectomies, 11.6% total lobectomies, the remainder were almost total operations. The number of visualized nerves was 1367. RESULTS Unilateral temporary damage of the NLR leading to temporary pareses of the vocal cords was recorded in 19 patients, i.e. 1.39%, bilateral transient paresis in one case, i.e. 0.07%. Permanent damage of one vocal cord after severing of the NLR occurred in 11 patients, i.e. 0.8%, bilateral lesions of the vocal cords were not recorded. CONCLUSION There are no extensive statistics of thyroid operations without reports on damage of the NLR. With the increasing number of radical operations of the gland also the number of departments increased which recommend unequivocally to seek and visualize the NLR. The authors results support this point of view. They use most frequently a modification of Wang's method and consider as the smallest extent of visualization of the NLR the distance between the branching of the inferior thyroid artery and the entry of the NLR into the larynx.

Abstract
Collisional avalanches are identified to be responsible for an 8-fold increase of the initial loss rate of a large (87)Rb condensate. We show that the collisional opacity of an ultracold gas exhibits a critical value. When exceeded, losses due to inelastic collisions are substantially enhanced. Under these circumstances, reaching the hydrodynamic regime in conventional Bose-Einstein condensation experiments is highly questionable.

Abstract
The discovery of endocannabinoids opens up new perspectives in experimental pain research. Here we present data for the excellent antinociceptive properties of the synthetic cannabinoid, R(-)-7-hydroxy-delta-6-tetra-hydrocannabinol-dimethylheptyl (HU-210), after intrathecal and oral administration in mice. It is known that cannabinoids depress motor activity. Therefore, these compounds are suspected of influencing antinociceptive tests. Our behavioural tests (RotaRod, tail flick) clearly show that HU-210 affects nociceptive behaviour even at dosages which do not yet influence motor activity. Moreover, spinal microdialysis (5 microl/min) in the dorsal horn of freely moving mice showed an enhancement of prostaglandin production during the formalin test. HU-210 applied via artificial cerebral spinal fluid during microdialysis perfusion increases prostaglandin concentrations under both baseline and formalin test conditions. Indomethacin reduces the HU-210 effect on pronociceptive prostaglandin production but does not reinforce the antinociceptive properties of HU-210. Thus, HU-210 shows antinociceptive properties that are independent of its influence on the prostaglandin pathway.

Abstract
The subject-matter of the main topic of this contribution focuses on the question concerning the criteria for the renunciation of therapy or for the decision to desist from treatment. The normative basis is the recognition of the principle that no one can be medically treated against his or her expressed will. Age in itself is not a morally justified argument to refuse medical treatment such as dialysis, organ transplants or the application of expensive medication. A therapy is to be rejected and also an already begun therapy is to be discontinued when this will neither cure nor ease the illness.

Abstract
Using a culture model of glial tumorigenesis, we identified a novel gene that was up-regulated in malignant mouse astrocytes following the loss of p53. The gene represents the murine homologue of pescadillo, an uncharacterized gene that is essential for embryonic development in zebrafish. Pescadillo is a strongly conserved gene containing unique structural motifs such as a BRCA1 C-terminal domain, clusters of acidic amino acids and consensus motifs for post-translational modification by SUMO-1. Pescadillo displayed a distinct spatial and temporal pattern of gene expression during brain development, being detected in neural progenitor cells and postmitotic neurons. Although it is not expressed in differentiated astrocytes in vivo, the pescadillo protein is dramatically elevated in malignant human astrocytomas. Yeast strains harboring temperature-sensitive mutations in the pescadillo gene were arrested in either G(1) or G(2) when grown in nonpermissive conditions, demonstrating that pescadillo is an essential gene in yeast and is required for cell cycle progression. Consistent with the latter finding, DNA synthesis was only observed in mammalian cells expressing the pescadillo protein. These results suggest that pescadillo plays a crucial role in cell proliferation and may be necessary for oncogenic transformation and tumor progression.

Abstract
BACKGROUND We performed a study to determine whether tissue harmonic imaging (THI) facilitates wall motion analysis at rest and whether these benefits extend through the stages of a dobutamine stress echocardiography (DSE) study. We also assessed the impact of THI on the feasibility of DSE in technically difficult patients. Finally we tested the hypothesis that THI by improving endocardial border definition (EBD) could enhance the interobserver agreement between trainees and experienced operators for interpreting DSE studies. METHODS Twenty unselected patients underwent DSE by standard protocol. Parasternal and apical views were obtained with the use of fundamental mode (FND) and THI at baseline, low dose, and peak stress. Segmental EBD was characterized as 1 to 4 (1 = excellent) and segmental wall motion was characterized as 1 to 4/x (1 = normal, x = unable to interpret) by a consensus of 2 experienced observers. A trainee in stress echocardiography independently scored all segments, and these results were compared with the consensus of the experienced readers. RESULTS EBD improved with THI in 26 +/- 6.7 of 48 segments per patient (54%, 95% confidence interval [CI] 0.40 to 0.68) and deteriorated with THI in only 2 +/- 2.7 (4%, 95% CI 0 to 0.09). Of the total of 48 segments per patient, a mean of 10 +/- 5.7 (21%, 95% CI 0.10 to 0.31) were of inadequate quality to be interpreted for wall motion on FND, and this changed to 4 +/- 3.4 (6%, 95% CI 0.06 to 0.12) on THI (P <.001). EBD improved in a similar degree in all DSE stages 53%, 54%, and 53% for rest, low dose, and peak stress, respectively. Six of the 20 study patients were deemed unsuitable for DSE on FND, and all were changed to suitable subjects on THI. Of the 205 segments deemed unsuitable for interpretation on FND, 140 (68%) were of the anterior and lateral walls of the LV. Improvement with THI was also more prominent on these walls. The mean coefficient of agreement (kappa) for wall motion analysis was 0.82 +/- 0.14 on FND and improved to 0. 92 +/- 0.09 on THI (P <.001). CONCLUSIONS THI dramatically improves EBD and the ability to confidently score segmental wall motion. Interobserver agreement is also significantly enhanced. These benefits extend to the peak stage of a DSE study. Routine use of THI may enhance the diagnostic accuracy of DSE and extend its application to technically difficult patients previously deemed unsuitable.

Abstract
Expression of the lung resistance protein (LRP) is associated with resistance to various anticancer drugs including melphalan and, therefore, may affect the clinical outcome in multiple myeloma (MM). To determine the clinical significance of LRP, we have compared LRP expression in bone marrow plasma cells with clinical parameters including response to chemotherapy and survival of previously untreated patients with MM (n = 72). LRP expression immunocytochemically assessed by means of the LRP-56 monoclonal antibody was positive (> or =10% staining plasma cells) in 44 (61%) samples. There was no correlation between LRP expression and age, sex, type of the paraprotein, serum creatinine, stage, beta2-microglobulin, serum lactate dehydrogenase, or C-reactive protein. However, LRP expression was more frequently observed in patients with a p53 deletion than in those without such a deletion (P = 0.01). The overall response rate for all of the patients evaluable for response to induction chemotherapy (n = 58) was 67%. The response rate was 87% for patients without LRP expression but only 54% for patients with LRP expression (P = 0.01). Kaplan-Meier analysis revealed that patients with LRP expression had a shorter overall survival (median, 33 months) than those without LRP expression (median not reached; P = 0.04). These data show that LRP expression is an important marker for clinical drug resistance and predicts a poor outcome in MM.

Abstract
Helical growth movements termed circumnutations occur in a number of different plant organs. The underlying mechanism are complicated. They consist of an endogenous as well as an erogenous component. Since circumnutations in sunflower hypocotyls occur also under gravity free conditions in Space, gravity is not necessary for them to arise. However, the changes of period and amplitude of circumnutations with the applied gravitational force indicate that gravity plays a modifying role. Models for circumnutations have to take these features into account. It seems natural to study minimum models with at least two oscillating units. Two-oscillator models for circumnutations have already been discussed. We have studied the interaction between two coupled oscillatory units. With this model we could simulate movements of hypocotyls. The results of simulations were compared with experimentally recorded movements of the Arabidopsis hypocotyl.

Abstract
Recently, it was recognized that an immune response develops along one of two major pathways. One leads to a destructive immune response (type 1), while the alternative leads to a nondestructive immune response (type 2). Our studies in animal models suggest that therapeutic vaccines induce a tumor-specific type 1 immune response while ineffective vaccines induce a type 2 response. These results have led us to examine the immune response in sentinel lymph nodes draining tumor vaccines of patients entered onto clinical trials for melanoma, breast and renal cell cancer.
