Abstract
BACKGROUND AND PURPOSE Papillary craniopharyngiomas (PCPs) are particularly challenging lesions requiring accurate diagnosis to plan the best therapy. Our aim was to define a narrow duct-like recess identified on MR imaging at the base of papillary craniopharyngiomas with a strict third ventricle location. MATERIALS AND METHODS A duct-like recess at the infundibular portion of craniopharyngiomas was observed on conventional T1WI and T2WI in 3 strict third ventricle papillary craniopharyngiomas in our craniopharyngioma series (n = 125). We systematically investigated this finding on the MR imaging of 2582 craniopharyngiomas and 10 other categories of third ventricle tumors (n = 690) published in the modern era (1986-2020). The diagnostic value and significance of this finding are addressed. RESULTS The duct-like recess was recognized in 52 papillary craniopharyngiomas, including 3 of our own cases, as a narrow canal-shaped cavity invaginated at the tumor undersurface, just behind the optic chiasm. This structure largely involves papillary craniopharyngiomas with a strict third ventricle topography (96%), follows the same diagonal trajectory as the pituitary stalk, and finishes at a closed end. The duct-like recess sign identifies the papillary craniopharyngioma type with a specificity of 100% and a sensitivity of 38% in the overall craniopharyngioma population. This finding can also establish the strictly intra-third ventricle location of the lesion with a 90% specificity and 33% sensitivity. These recesses appear as hypointense circular spots on axial/coronal T1WI and T2WI. Their content apparently corresponds to CSF freely flowing within the suprasellar cistern. CONCLUSIONS The presence of a duct-like recess at the infundibular portion of a third ventricle tumor represents a distinctive hallmark of papillary craniopharyngiomas that can be used as a simple MR imaging sign to reliably diagnose these lesions.

Abstract
The TJ-II stellarator presently in operation at the National Laboratory of Fusion is subject to radiological surveillance in compliance with the Spanish Nuclear Regulation. During its pulsed operation hard X-rays are emitted by the runaway electrons, and soft X-rays are generated by bremsstrahlung of thermalized electrons. Inside the experimental hall, the plasma heating systems and some active diagnostics are additional sources of radiation. Outside the experimental hall, some auxiliary systems, such as high-voltage power supplies, must be checked for radiological influence. In order to verify the adequate radiological classification of the different working areas, 15 dosemeters are distributed in radiologically controlled areas close to the machine, as well as in areas of public use in the TJ-II building. The integrated dose equivalent is analyzed to help establish the range of radiological influence of the stellarator. The results of the period 2015-20 are presented and analyzed.

Abstract
INTRODUCTION With the increasing incidence of food allergies, the presence of eosinophils (Eos) in the gastrointes tinal mucosa has received increased attention, particularly in the esophagus and colon. However, normal values for the Eos count in the stomach and duodenum in pediatric patients are still limited. THE OBJECTIVE of this study was to estimate Eos reference values in stomach and duodenal biopsies of children referred to upper gastrointestinal endoscopy. PATIENTS AND METHODS Cross-sectional study of biopsies from symptomatic children referred to upper gastrointestinal endoscopy. The endoscopic report, Rapid Urease Test for the presence of H. pylori, and the quantitative histological evaluation (number of cells/HFP, high power field) were analyzed. The Eos distribution is described as mean and standard deviation, and also as percentiles since the counts did not have a normal distribution. Statistical analysis included x2 test, Wilcoxon test, analysis of variance, and linear regression curves were evaluated as appropriate. RESULTS Of the 170 patients referred to endoscopy, 72 met "normal" criteria (normal endoscopy in macroscopic analysis, negative Rapid Urease Test, and normal biop sy). The median age was 11 years (range 4-16), and 68% were girls. The Eos count (mean ± 1SD) in gastric antrum (n = 72) was 1.13 ± 1.79 Eos/HPF; in gastric body (n = 27), 1.06 ± 1.79 Eos/HPF; and in duodenum (n = 30), 10.44 ± 7.09 Eos/HPF. There were no significant differences by age and sex, or by H. pylori infection (p = 0.095). CONCLUSIONS We propose an Eos count of 0-3 Eos/HPF for the gastric body, 0-3 Eos/HPF in the antrum, and 3-17 Eos/HPF in the duodenum as a normal range for gastric mucosa in children. This study suggests that in areas with a high prevalence of H. pylori infec tion, the count of Eos does not seem to be a distinctive element and that Eos are commonly present in the gastroduodenal mucosa.

Abstract
Nerve growth factor (NGF) in semen is responsible for triggering ovulation after copulation in camelids. Interaction of NGF with its cognate receptors results in a preovulatory luteinising hormone (LH) surge that leads to ovulation, but the pharmacokinetics of NGF and the mechanism by which it mediates LH release are unknown. In an effort to elucidate the site and mechanism of action involved, the objective of this study was to determine whether the decline in the LH surge occurs as a result of pituitary depletion (i.e. diminished response to gonadotrophin-releasing hormone (GnRH)) or as an obtunded response at the level of the hypothalamus (diminished GnRH). Adult nonpregnant, nonlactating llamas (n=18) were synchronized by the administration of an ovulatory dose of a GnRH analogue (100μg IM; Fertiline, Vetoquinol). At 10 to 14 days later, the ovaries were examined to confirm the presence of a dominant follicle measuring ≥ 7mm, and a jugular catheter was put in place. The following day, a pretreatment blood sample was taken, and llamas were treated intravenously with 1mg of purified NGF from llama seminal plasma. Blood samples were taken every 30min for 7h from the time of NGF treatment. After the last blood sample was taken, llamas were treated with NGF (n=6; 1mg IV), GnRH (n=5; 100μg IV), or saline (Sal; IV; n=6), and blood samples were taken every 30min for another 7h. The ovaries were examined 48h after initial NGF treatment, via transrectal ultrasonography, to detect ovulation. Plasma was harvested and stored for analysis of LH concentration by radioimmunoassay. Data were compared using ANOVA for repeated measures, and single-point data were analysed using paired t-tests. As expected, most llamas ovulated in response to the initial NGF treatment (5 out of 5 in NGF-GnRH; 5 of 6 in NGF-NGF; 5 of 6 in NGF-Sal). Compared with pretreatment values, all llamas showed a 4-fold increase in plasma LH concentrations within 2h of the initial NGF treatment (P<0.05). Plasma LH concentrations peaked at 3h after initial NGF treatment and began to decline 4.5 to 5h after treatment (P<0.05). Plasma LH concentrations continued to decline following the second dose of NGF or Sal, whereas a transient elevation of LH was detected in llamas treated with GnRH (P<0.05). The LH concentration returned to basal levels (pretreatment) 8, 12, and 13h after NGF treatment in llamas treated with NGF-Sal, NGF-GnRH, and NGF-NGF, respectively. We conclude that the lack of LH response to the second dose of NGF is not because of pituitary depletion but rather due to diminished GnRH. The latter may be attributed to either a downregulation of NGF receptors within the hypothalamus or to temporary depletion of GnRH at the nerve terminals within the median eminence.

Abstract
This paper presents results from an experiment designed to improve the understanding of the relationship between extreme breaking waves and their mechanical loading on heritage offshore lighthouses. The experiment, conducted at La Jument, an iconic French offshore lighthouse, featured several records of wave, current and structure accelerations acquired during severe storm conditions, with individual waves as high as 24 m. Data analysis focuses on a storm event marked by a strong peak in the horizontal accelerations measured inside La Jument. Thanks to stereo-video wave measurements synchronized to the acceleration record we were able to identify and describe the breaking wave responsible for this intense loading. Our observations suggest that this giant wave (19 m high) had a crest elevation high enough to directly hit the lighthouse tower, above the substructure. This paper reveals the potential for conducting ambitious field experiments from offshore lighthouses in order to collect valuable storm waves and wave loading observations. This offers a possible second service life for these heritage structures as in situ laboratories dedicated to the study of the coastal hydrodynamics and its interaction with marine structures. This article is part of the theme issue 'Environmental loading of heritage structures'.

Abstract
Arginine methyltransferases critically regulate cellular homeostasis by modulating the functional outcome of their substrates. The protein arginine methyltransferase 5 (PRMT5) is an enzyme involved in growth and survival pathways promoting tumorigenesis. However, little is known about the biologic function of PRMT5 and its therapeutic potential in multiple myeloma (MM). In the present study, we identified and validated PRMT5 as a new therapeutic target in MM. PRMT5 is overexpressed in patient MM cells and associated with decreased progression-free survival and overall survival. Either genetic knockdown or pharmacological inhibition of PRMT5 with the inhibitor EPZ015666 significantly inhibited growth of both cell lines and patient MM cells. Furthermore, PRMT5 inhibition abrogated NF-κB signaling. Interestingly, mass spectrometry identified a tripartite motif-containing protein 21 TRIM21 as a new PRMT5-partner, and we delineated a TRIM21-dependent mechanism of NF-κB inhibition. Importantly, oral administration of EPZ015666 significantly decreased MM growth in a humanized murine model of MM. These data both demonstrate the oncogenic role and prognostic relevance of PRMT5 in MM pathogenesis, and provide the rationale for novel therapies targeting PRMT5 to improve patient outcome.

Abstract
Neurotrophins are molecules involved in the development and survival of neurons and its cellular projections. Results of recent studies have implicated the local role of the high affinity neurotropin receptor, trkA, in bovine ovarian follicle selection and early luteogenesis (Carrasco et al. 2016 Reprod. Biol. Endocrinol. 14, 47), but innervation and neuropeptide control remains an unexplored aspect of ovarian function. P75 is the low-affinity receptor for all neurotrophins and is expressed in ovarian tissue. The objective of this study was to explore the distribution of P75 neurons and fibres within the ovary and to examine the relationship of these components with follicular development. The ovaries of cows (n = 5) were collected at the time of slaughter, 36 h after induced luteolysis (i.e. proestrus). The ovaries were fixed in 4% paraformaldehyde for 48 h, and samples from the ovarian hilus, medulla, and cortex (3 blocks per ovary) were cryo-sectioned (20–50 µm). Tissue sections were incubated for 48 h with a rabbit antibody against rat P75 or a mouse monoclonal antibody against neurofilament. Immunodetection was visualised by an amplification procedure with horseradish peroxidase using nickel DAB as a chromogen. Sections were counterstained with nuclear fast red for follicle identification. Immunoreactive cell bodies were counted in 10 to 20 fields (40×) per section, and data were expressed based on ovarian areas (cortex, medulla, or hilus) as an average count per 40× field per animal. Data among ovarian regions were compared by ANOVA; differences were considered significant when P < 0.05. Antral follicles ≤5 mm displayed strong immunoreactivity in the theca layer, without reaction in the granulosa cells. In contrast, preovulatory follicles were devoid of P75 immuno-reactivity in the theca layer. Oval P75 immunoreactive neuron-like cells were present in all ovarian areas studied. The neuronal nature of the P75 immunoreactive cells was confirmed by the presence of a similar pattern when adjacent sections were stained for neurofilaments, a protein characteristic of neurons. In the stroma of the ovarian cortex and medulla, neurons were present individually (scattered) rather than grouped; however, a dense network of neurons and fibres was detected immediately beneath the ovarian surface epithelium. No differences between the cortex, medulla, and hilus were found in the mean number of immunoreactive cells (10.6 ± 2.8, 14.4 ± 3.6 and 13.9 ± 2.0 cells/40× field, respectively). Immunoreactive neuron-like cells and fibres were in close proximity to blood vessels in the ovarian medulla. Corpora lutea were devoid of P75 immunoreactivity. In conclusion, results document the existence of a neuronal network in the bovine ovary, displaying an association with follicles at different stages of development. The abundance of neuronal components (i.e. neuron cell bodies and axons) in the ovarian stromal and surface epithelium implies a role of innervation (either extrinsic or intrinsic) in the control of ovarian follicular development and function.

Abstract
Gonadal steroids hormones indirectly regulate gonadotropin-rleasing hormone (GnRH) secretion. Kisspeptin (Kp) co-expresses steroid receptors and modulates GnRH release. The objective of the study was to characterise the number and proportion of GnRH and Kp immunoreactive cells and their association in the preoptic area (POA) and hypothalamus during different phases of the oestrous cycle in cows. Daily ovarian ultrasonography was performed to detect follicle development and ovulation (Day 0) after prostaglandin treatment. On Day 5, cows were assigned randomly to the following groups: proestrus (n = 2), metestrus (n = 2) or diestrus (n = 3). Cows in the diestrus group were killed on Day 8. Cows in the proestrus and metestrus groups were given luteolytic dose of prostaglandin on Day 5.5 and Day 6 and were killed on Day 7 and 24 h after the ensuing ovulation, respectively. Cow heads were perfused with 4% paraformaldehyde via the carotid arteries to fix the brain in situ. The brain-stem (rostral portion of the POA to the mamillary body) was isolated by dissection and placed in 4% paraformaldehyde for 48 h. Following cryoprotection, the tissue block containing the POA and hypothalamus was frozen at –80°C and sectioned serially at a thickness of 50 mm using a cryostat microtome. Every 20th free-floating section was processed for double labelling using 2 sequential immuno-peroxidase reactions and ABC staining; Kp was immuno-labelled with Nickel-DAB at a dilution of 1:10,000 rabbit anti-kisspeptin (AC566, INRA, France), and GnRH was stained with DAB using 1:40,000 rabbit anti-GnRH (LR-5, Dr Benoit). The numbers of neuron cell bodies and fibres were recorded in different areas of the POA and the hypothalamus by brightfield microscopy using 10× and 40× objective lenses. Data were compared among groups by ANOVA. Major aggregations of Kp cells were localised in the mPOA, OVLT, and ARC. Overall, the number of Kp cells was higher in the metestrus v. diestrus group (719 ± 94 v. 378 ± 8; P = 0.01), but was similar to the proestrus group (558 ± 9). The number of Kp cells in the POA (mPOA, OVLT) tended to be higher in the metestrus v. diestrus group (395 ± 56 v. 147 ± 44; P = 0.06), and was intermediate in the proestrus group (206 ± 6). The number of Kp cells in the ARC did not differ among groups (metestrus 310 ± 26, diestrus 206 ± 53, proestrus 321 ± 99; P = 0.4). The number of GnRH cells bodies was not different among groups (metestrus 40 ± 3, diestrus 50 ± 9, proestrus 43 ± 8; combined; P = 0.8), and the distribution was higher in the POA (metestrus 25 ± 2, diestrus 30 ± 3, proestrus 33 ± 2) than hypothalamus. The proportion of GnRH cells in apposition to Kp fibres tended to be highest in the proestrus v. metestrus and diestrus groups (50.5 ± 1% v. 34.1 ± 9% and 31.4 ± 3%; P = 0.09). In conclusion, the number of Kp immunoreactive cells, but not GnRH cells, present in the POA and hypothalamus changed among different phases of the oestrous cycle due primarily to an increase in number of Kp cells in POA during metestrus. The proestrous phase was associated with an increase in apposition between Kp fibres and GnRH cells.

Abstract
INTRODUCTION Trisomy 9 is an unusual chromosome abnormality in live-born patients, which is frequently accompanied by functional and structural anomalies of the central nervous system. Among many other alterations, several studies have been published in the English-speaking literature that show an association between chromosome 9 abnormality and pathologies affecting the choroid plexuses. CASE REPORT We report the case of a 4-month-old male with trisomy 9 mosaicism associated to hydrocephalus secondary to choroid plexus hyperplasia, who was referred due to a clinical picture of intracranial hypertension. The cerebrospinal fluid (CSF) drainage procedure that was initially chosen caused massive ascites due to an excessive production of CSF, and led to a cascade of multiple surgical interventions, which included endoscopic and drainage procedures. CONCLUSIONS This is another example of an association between choroid plexus pathologies and chromosome 9 abnormality. Due to its scarce incidence, diagnosis of hydrocephalus secondary to plexus hyperplasia is difficult, as is selecting its most suitable treatment. In this type of hydrocephalus there is a double pathophysiological mechanism, which involves an increase in CSF production and a decrease in its reabsorption. Despite taking these considerations into account, the treatment of hydrocephalus secondary to plexus hyperplasia is a real challenge that usually leads to multiple surgical interventions ranging from plexectomy or coagulation of the choroid plexuses to the implantation of CSF drainage devices.

Abstract
BACKGROUND The prognosis of children with juvenile dermatomyositis (JDM) has improved remarkably since the 1960's with the use of corticosteroid and immunosuppressive therapy. Yet there remain a minority of children who have refractory disease. Since 2003 the sporadic use of biologics (genetically-engineered proteins that usually are derived from human genes) for inflammatory myositis has been reported. In 2011-2016 we investigated our collective experience of biologics in JDM through the Childhood Arthritis and Rheumatology Research Alliance (CARRA). METHODS The JDM biologic study group developed a survey on the CARRA member experience using biologics for Juvenile DM utilizing Delphi consensus methods in 2011-2012. The survey was completed online by the CARRA members interested in JDM in 2012. A second survey was similarly developed that provided more opportunity to describe their experiences with biologics in JDM in detail and was completed by CARRA members in Feb 2013. During three CARRA meetings in 2013-2015, nominal group techniques were used for achieving consensus on the current choices of biologic drugs. A final survey was performed at the 2016 CARRA meeting. RESULTS One hundred and five of a potential 231 pediatric rheumatologists (42%) responded to the first survey in 2012. Thirty-five of 90 had never used a biologic for Juvenile DM at that time. Fifty-five of 91 (denominators vary) had used biologics for JDM in their practice with 32%, 5%, and 4% using rituximab, etanercept, and infliximab, respectively, and 17% having used more than one of the three drugs. Ten percent used a biologic as monotherapy, 19% a biologic in combination with methotrexate (mtx), 52% a biologic in combination with mtx and corticosteroids, 42% a combination of a biologic, mtx, corticosteroids (steroids), and an immunosuppressive drug, and 43% a combination of a biologic, IVIG and mtx. The results of the second survey supported these findings in considerably more detail with multiple combinations of drugs used with biologics and supported the use of rituximab, abatacept, anti-TNFα drugs, and tocilizumab in that order. One hundred percent recommended that CARRA continue studying biologics for JDM. The CARRA meeting survey in 2016 again supported the study and use of these four biologic drug groups. CONCLUSIONS Our CARRA JDM biologic work group developed and performed three surveys demonstrating that pediatric rheumatologists in North America have been using multiple biologics for refractory JDM in numerous scenarios from 2011 to 2016. These survey results and our consensus meetings determined our choice of four biologic therapies (rituximab, abatacept, tocilizumab and anti-TNFα drugs) to consider for refractory JDM treatment when indicated and to evaluate for comparative effectiveness and safety in the future. Significance and Innovations This is the first report that provides a substantial clinical experience of a large group of pediatric rheumatologists with biologics for refractory JDM over five years. This experience with biologic therapies for refractory JDM may aid pediatric rheumatologists in the current treatment of these children and form a basis for further clinical research into the comparative effectiveness and safety of biologics for refractory JDM.

Abstract
Classical studies established that the removal of one of the paired organs produces a compensatory effect on the remaining organ. In the bovine ovary this aspect has not been examined in detail. We took advantage of follicular and luteal profiles from a previous study to retrospectively examine the effects of ovariectomy before and after ovulation on follicular dynamics of the remaining ovary in cattle. To characterise the prevalence and distribution of tyrosine kinase receptor A in the bovine ovary, the original design involved unilateral ovariectomy of cows at different stages of the periovulatory period. For the purposes of the present study, we combined data into 2 groups, a preovulatory group (n = 6 cows) and a post-ovulatory group (n = 5 cows), to provide sufficient data for statistical interpretation. The cows were examined daily by transrectal ultrasonography to determine the ovarian status. For the preovulatory group, a luteolytic dose of prostaglandin was administered when the dominant follicle of the second follicular wave reached ≥10 mm, and the ovary containing the dominant follicle was removed within 48 h. For the post-ovulatory group, ovariectomy was performed on the ovary containing the newly formed corpus luteum between Days 2 to 6 (Day 0 = ovulation). Unilateral ovariectomy was performed by colpotomy under caudal epidural anaesthesia using a chain ecraseur. After ovariectomy, cows were examined daily by ultrasonography from ovariectomy to the completion of an interovulatory interval (period between 2 ovulations). Single-point data were compared between groups by t-test, and binomial data were compared between groups by Fisher’s exact test. Double ovulations were detected in 3/6 ovariectomized in the preovulatory period and 2/5 ovariectomized in the post-ovulatory period. The first ovulation after ovariectomy tended to occur earlier in the preovulatory group than in the post-ovulatory group (P = 0.08), which was attributed primarily to the development of oversized persistent dominant follicles (~20 mm in diameter for ≥7 days in absence of a corpora lutea) in 2 of 5 cows in the post-ovulatory ovariectomy group. The interovulatory interval after ovariectomy was shorter in the post-ovulatory group than in the preovulatory group (14.6 ± 0.3 v. 20.3 ± 0.6 days; P = 0.01). No distinct patterns were detected in follicular and luteal dynamics between the pre- and post-ovulatory ovariectomy groups. The number of follicles ≥3 mm detected by ultrasonography was greater in the post-ovulatory ovariectomy group than in the preovulatory group on Days 6, 7, 8, and 16 of the first interovulatory interval after ovariectomy. In conclusion, results of this retrospective study support the concept that follicular and luteal effects of removal of one ovary are influenced by the timing of ovariectomy relative to ovulation. A prospective study involving a comparison of ovarian dynamics of the same cows before and after unilateral ovariectomy will provide a better understanding of the disruption that take place and the mechanisms controlling it.

Abstract
Transfusion-related acute lung injury (TRALI) is a life-threatening intervention that develops within 6 hours of transfusion of one or more units of blood, and is an important cause of morbidity and mortality resulting from transfusion. It is necessary to dismiss other causes of acute lung injury (ALI), like sepsis, acute cardiogenic edema, acute respiratory distress syndrome (ARDS) or bacterial infection. There are two mechanisms that lead to the development of this syndrome: immune-mediated and no immune- mediated TRALI. A common theme among the experimental TRALI models is the central importance of neutrophils in mediating the early immune response, and lung vascular injury. Central clinical symptoms are dyspnea, tachypnea, tachycardia, cyanosis and pulmonary secretions, altogether with other hemodynamic alterations, such as hypotension and fever. Complementary to these clinical findings, long-term validated animal models for TRALI should allow the determination of the cellular targets for TRALI-inducing alloantibodies as well as delineation of the underlying pathogenic molecular mechanisms, and key molecular mediators of the pathology. Diagnostic criteria have been established and preventive measures have been implemented. These actions have contributed to the reduction in the overallnumber of fatalities. However, TRALI still remains a clinical problem. Any complication suspected of TRALI should immediately be reported.

Abstract
PURPOSE We report the response rate in children older than 18 months with stage 4 Neuroblastoma, using a modified dose-intensive, response-adaptive, induction mN7 protocol. METHODS From 2005 to 2012, 24 patients were treated with the mN7 protocol. Phase 1 included five MSKCC N7 cycles and surgery and two high-dose cyclophosphamide-topotecan (HD-CT) cycles for those who did not achieve complete remission (CR) and negative bone marrow (BM) minimal residual disease (MRD) status (CR+MRD-). Phase 2 consisted of myeloablative doses of topotecan, thiotepa and carboplatin plus hyperfractionated RT. Phase 3 included isotretinoin and 3F8 immunotherapy plus GM-CSF. BM MRD was monitored using GD2 synthase, PHOX2B and cyclin D1 mRNAs. RESULTS After 3 cycles, all patients showed BM complete histological clearance and 6 (25 %) were MRD-. Twenty of 21 s-look surgeries achieved macroscopic complete resection. After 5 cycles and surgery, (123)I-MIBG scan was negative in 15 (62.5 %) cases, BM disease by histology was negative in 23 (96 %) and 10 (42 %) patients were MRD-. Twelve (50 %) pts were in CR, 2 in very good partial response (VGPR), 9 partial response (PR) and one had progressive disease. With 2 HD-CT extra cycles, 17 (71 %) pts achieved CR+MRD- status moving to phase 2. Overall and event-free survival at 3 years for the 17 patients who achieved CR+MRD- is 65 and 53 %, respectively, median follow-up 47 months. Seven (29 %) patients never achieved CR+MRD-. Univariate Cox regression analysis shows CR+MRD- status after mN7 induction as the only statistically significant prognostic factor to predict overall survival. CONCLUSIONS mN7 induction regimen produced a CR+MRD- rate of 71 %. CR+MRD- status following induction was the only predictive marker of long-term survival.

Abstract
Ovulation-inducing factor/nerve growth factor (OIF/NGF) influences ovulation and corpus luteum (CL) size and function in camelids and, remarkably, cows. The ovulation effect in induced ovulators is mediated at the hypothalamo-pituitary-axis, but the site and mechanism of action of the luteotrophic effect is unknown. This mechanism may be an important aspect of OIF/NGF in spontaneous-ovulators. The objective of this experiment was to detect changes in expression of the high affinity OIF/NGF receptor (TrkA) in the ovary during the periovulatory period in cattle. Cows (n = 14) were examined daily by transrectal ultrasonography to determine the day of ovulation (Day 0), and were assigned randomly to be unilaterally ovariectomized on Day 2, 4, 6, or in the preovulatory period before or after the LH surge. Cows assigned to preovulatory groups were given a luteolytic dose of prostaglandin when the dominant follicle of the second follicular wave was ≥10 mm and growing. Cows assigned to the pre-LH group were ovariectomized 24 h after prostaglandin treatment. Cows assigned to the post-LH group were given LH 24 h after prostaglandin treatment and were ovariectomized 18–20 h later. Cows were allowed to rest for one complete interovulatory interval and re-assigned to a different day-group on which the remaining ovary was removed (n = 4 to 5 ovaries/day-group). Ovaries were fixed in paraformaldehyde, and 5-μm sections of ovarian tissue representing the dominant follicle, largest subordinate follicle, and the CL were treated for enzymatic antigen retrieval and blocked in 1% BSA for 1 h. Slides were incubated overnight with the primary antibody (rabbit anti-human TrkA) and for 2 h with the secondary antibody (goat anti-rabbit IgG). Slides were evaluated by fluorescence microscopy. Images of 3 arbitrarily chosen fields (40×) were captured for each structure for each day-group, and the average proportion of immunoreactive cells in the theca layer and luteal tissue was estimated using ImageJ software (National Institutes of Health, Bethesda, MD, USA). The intensity of individual cell immunofluorescence was also scored as no reaction (0), faint (1), weak to moderate (2), or strong (3). Data were compared among groups by two-way ANOVA. The proportion of immunoreactive cells was higher in the dominant follicle than in the subordinate follicle or the CL (P < 0.001); no effect of day-group or interaction was detected. The intensity score increased from faint on Day 2 to strong on Day 6, and remained strong in the pre- and post-LH groups. A discernible pattern of change in intensity score was not evident for the subordinate follicle or the CL. The greater proportion of TrkA positive cells and greater immunoreactive intensity in the maturing dominant follicle support the hypothesis that the luteotrophic effect of OIF/NGF in cattle is a result of a local increase in the expression of TrkA in the theca layer of the dominant follicle.

Abstract
Abstract
HER3 (ERBB3) is a member of the EGFR/HER family of receptor tyrosine kinases (RTK), consisting of EGFR, HER2, HER3 and HER4. Unlike the other HER family members, HER3 lacks intrinsic tyrosine kinase activity and therefore needs to form heterodimers with EGFR, HER2 or other kinase-proficient RTKs to be functionally active. Dimerization is induced by overexpression of EGFR or HER2 in a ligand-independent (LI) manner. In this process HER3 acts as a driver in divergent cancer types including HER2-positive breast cancer (BC) via induction of the PI3K-AKT pathway. Alternatively, heregulin (NRG1/HRG), the major HER3 ligand, induces a conformational shift in HER3 which leads to dimer formation with a partner RTK in a ligand-dependent (LD) manner.
We have developed an antagonistic human monoclonal antibody against HER3, termed MEDI3379, and tested it in multiple breast cancer cell lines. We observed effective suppression of constitutive pHER3 and pAKT with MEDI3379, leading to anti-proliferation effects in cell culture models. Preclinical evaluation of MEDI3379 demonstrated antitumor activity in several orthotopic BC xenografts in nude mice which did not express HRG. For example, the BC xenograft model BT474 with amplified HER2 responded to MEDI3379 (65% dTGI). In conclusion, our findings with targeting of HER3 in mouse models support continued development of MEDI3379 for cancer.

Abstract
Two experiments were conducted to evaluate the comparative feeding value of dried shredded sugarbeets (DSSB; 0, 20, and 40% of diet DM) as a replacement for steam-flaked corn (SFC) in finishing diets for feedlot cattle. In Exp. 1, 60 calf-fed Holstein steers (476 ± 6.3 kg) were used in a 97-d finishing trial. Substitution of SFC with DSSB did not affect ADG or DMI (P > 0.20). Increasing DSSB decreased gain efficiency (ADG:DMI; linear effect, P = 0.04) and dietary NE (linear effect, P = 0.03). Given that SFC has a NE(m) value of 2.38 Mcal/kg, the replacement NE(m) and NE(g) values for DSSB were 1.94 and 1.29 Mcal/kg, respectively. There were no treatment effects (P > 0.20) on carcass characteristics. In Exp. 2, 6 cannulated Holstein steers (205 kg) were used in a replicated 3 × 3 Latin square design to evaluate treatment effects on digestion. Ruminal digestion of starch, NDF, and feed N were not affected (P > 0.10) by DSSB, although ruminal OM digestion tended to increase (linear effect, P < 0.08). Replacing SFC with DSSB decreased flow of starch to the small intestine, but it increased flow of microbial N (linear effect, P = 0.05). There were no treatment effects (P > 0.14) on postruminal digestion of OM, NDF, starch, or feed N or total tract digestion of OM, starch, and N. Substitution of DSSB increased (linear effect, P = 0.05) total tract NDF digestion and decreased (linear effect, P = 0.05) dietary DE (Mcal/kg). Given that SFC has a DE value of 4.19 Mcal/kg, the replacement DE value of DSSB was 3.68 Mcal/kg. There were no treatment effects (P > 0.12) on ruminal pH or total VFA; however, DSSB decreased propionate (linear effect, P = 0.05) and increased acetate (linear effect, P = 0.07), butyrate (linear effect, P = 0.05), valerate (linear effect, P = 0.04), and estimated methane production (linear effect, P = 0.05). We concluded that DSSB may replace SFC in finishing diets at levels of up to 40% without detrimental effects on ADG and carcass characteristics. The NE value of DSSB is 82% that of SFC (DM basis). Partial replacement of SFC with DSSB alters ruminal VFA patterns, increasing estimated methane energy loss and slightly decreasing the efficiency of DE utilization.

Abstract
A cortisol metabolite, 11-ketoetiocholanolone (11-k), is widely used in monitoring stress in several vertebrates, and can be detected by immunoassay. However, these assays have certain limitations with respect to specificity. Also, differences in the excretion of faecal glucocorticoid metabolites (FGM) among species and even between sexes make validation necessary in each case. Therefore, our aims were, first, to develop and validate a high-pressure liquid chromatography–tandem mass spectrometry (HPLC–MS/MS) methodology for monitoring 11-k in faeces of Iberian red deer (Cervus elaphus hispanicus), and second, to investigate the capability of our method to determine variations of this FGM in a longitudinal study. Third, and finally, we assessed the correspondence between faecal 11-k concentrations and plasma cortisol. An adrenocorticotropic hormone (ACTH) test was performed on six red deer stags translocated and kept in captivity for a week and faecal samples were collected twice a day. One single blood and faecal sample from another seven stags was also collected after 2 weeks in captivity. The results of the longitudinal study showed a first peak in 11-k 36 h after the ACTH test and handling, and a second peak at 120 h of being kept indoors. Maximum concentrations of 11-k ranged from 22.71 to 375.68 ng/g. In the second stag group, 11-k concentrations of 25.09 ± 20.53 ng/g had a correlation of r2 = 0.88 with the concentration of plasma cortisol, which was 54.6 ± 55.1 ng/mL. This technique is capable of detecting changes in the concentrations of faecal 11-k. The values determined have a good correlation with the cortisol concentration in blood, and we also detected differences in different individuals’ responses to the same stressors.

PATIENTS A total of 53 patients with acute myocardial infarction with persistent ST segment elevation treated with the same fibrinolytic therapy. A control group of 53 biologically similar subjects was included. INTERVENTIONS None. MAIN MEASUREMENTS Baseline characteristics; frequency of wild-type genotype (Thr325Thr) and of those corresponding to the mutation (Thr325LLe and LLe325lle), TAFI levels at 6 h, 34 h and 3 months post-fibrinolysis; ejection fraction; Killip-Kimball; reperfusion; ischemic recurrence; death. RESULTS No relationship was found between biological features and TAFI concentration. The latter was significantly higher in infarct patients (p<0.01) and in the mutation group (p<0.01). The homozygotic mutation (Ile325Ile) was significantly higher in infarct patients (p<0.01). Reperfusion was significantly associated with lower body mass index (p=0.02. OR 0.22. 95% CI), ejection fraction (p=0.004. OR 0.91. 95% CI), triglyceride level (p=0.01. OR 1.02. 95% CI) and cholesterol levels (p=0.001. OR=0.84. 95% CI). Mutation was associated to a significant fall in post-fibrinolysis concentration TAFI antigen and functional TAFI (p=0.01) and (p=0.02), and lower frequency of reperfusion. Reperfusion was associated with a significant post-fibrinolysis reduction in the level of TAFI antigen (p=0.02). Recurrence was associated to a significantly higher post-fibrinolysis level (p=0.05. OR=0.84. 95% CI). This was more frequent in mutation. Post-fibrinolysis TAFI antigen concentration was significantly lower in non-recurrence patients (p=0.028. OR=1.03. 95% CI). CONCLUSIONS A higher concentration of TAFI is associated to a worse prognosis in reperfusion and recurrence in acute myocardial infarction treated with fibrinolysis. Homozygotic mutation was more frequent in myocardial infarction patients. Wild genotype is associated to a better prognosis. Mutation is associated to a higher expression of TAFI.

Abstract
INTRODUCTION. Subependymomas are benign neoplasms intimately related to the ventricular system which only exceptionally associate hemorrhagic events. We present neuroradiological and pathological evidences of intratumoral hemorrhage within a single case of subependymoma operated on at our institution. Additionally we analyze retrospectively the well-defined reports of similar cases published in the scientific literature. CASE REPORT. A 71-year-old man on anticoagulant therapy presented with abrupt and progressive deterioration of his level of consciousness. Emergent computed tomography and magnetic resonance imaging evidenced signs of acute bleeding within a mass located at the frontal horn of the left lateral ventricle, producing obstructive biventricular hydrocephalus. The lesion was immediately and completely removed through a left frontal transcortical approach. Pathological diagnosis was consistent with subependymoma displaying areas of microhemorrhage. After surgery the patient developed global anterograde and retrograde amnesia. CONCLUSIONS. A spontaneous hemorrhagic event within an asymptomatic lateral ventricle subependymoma can result in a surgical emergence as a consequence of sudden obstruction of cerebrospinal fluid pathways. Prompt and radical surgical removal of the mass, which allows a rapid resolution of hydrocephalus and prevents the risk of rebleeding, may constitute the safest management strategy.
