Abstract
The present study aimed to describe the personality and psychopathology dimensions reported by veterans seeking organ transplantation, as well as to identify those dimensions associated with subsequent presurgical recommendations and transplant outcomes. Data were collected from 245 veterans undergoing a pretransplant psychological evaluation that included the MMPI-2-RF. Three treatment recommendations resulting from these evaluations, three recommendation adherence variables, and two transplant outcomes were extracted from electronic medical records. The sample's MMPI-2-RF scale scores were compared to the normative sample and two other presurgical samples and contrasted across subgroups defined by organ transplanted. Point-biserial correlations and logistic regression analyses examined associations between MMPI-2-RF scale scores and the eight measured outcomes. Results indicated that over-reporting, internalizing tendencies, negative emotionality, and a lack of positive emotions were uniquely predictive of mental health treatment recommendation, whereas somatic over-reporting, externalizing tendencies, and disinhibition were predictive of substance use treatment recommendation. Veterans who reported higher levels of activation were less likely to initiate mental health treatment. Finally, veterans with greater somatic preoccupation were less likely to be listed for organ transplant. More suspicious and mistrustful veterans were less likely to receive the transplant. These findings offer support for the role of the MMPI-2-RF in veteran pretransplant evaluations.

Abstract
Introduction/Objective
Glomus tumors are mesenchymal neoplasms with glomus body type modified smooth muscle cell differentiation. Most glomus tumors have a benign clinical course. However, rarely, they display malignant histologic features.
Methods/Case Report
We undertook a retrospective study using a natural language search in CoPath to find surgical pathology cases from 1993-2020 containing “glomus” in the pathology diagnosis. All relevant cases were included, and clinicopathologic data were reviewed in detail.
Results (if a Case Study enter NA)
A total of 66 tumors were identified, of which 42 were in female (63.6%) and 24 in male (36.4%) patients. The age at surgery ranged from 22 to 79 years with a median of 47.5. Females were significantly younger than males at presentation (p=0.025) by 8.8±3.8 years. Forty cases (60.6%) were located on the digits, 24 in nonvisceral soft tissue of extremities, trunk, and lip (36.4%), and one each in stomach and breast parenchyma. Sixty-three (95.5%) were benign (of which one recurred locally), 2 (3%) were malignant, and 1 (1.5%) was atypical. Four (6%) were multicentric. One case showed mixed histology (oncocytic and classic features) and one was classified as glomangiomatosis. The malignant cases each presented with a single tumor in lower extremity soft tissue in female patients (aged 33 and 49 years). The tumors measured 0.5 and 1.8 cm respectively and showed marked cytologic atypia in both and increased mitotic activity in the first. They were both completely excised.
Conclusion
The majority of glomus tumors are benign, however 3% are malignant. The most common location is the digits, followed by soft tissue. This tumor is more commonly seen in female patients. Unusual histologic variants such as glomangiomatosis and oncocytic component at times may create some difficulty to reach the diagnosis, especially on small biopsies. Unusual locations such as stomach can lead to a wrong diagnosis such as carcinoid, especially in a small biopsy material.

Abstract
Schwann cells naturally support axonal regeneration after injury in the peripheral nervous system, and have also shown a significant, albeit limited, ability to support axonal growth and remyelination after grafting to the central nervous system (CNS). It is possible that Schwann cell-induced axonal growth in the CNS could be substantially increased by genetic manipulation to secrete augmented amounts of neurotrophic factors. To test this hypothesis, cultured primary adult rat Schwann cells were genetically modified using retroviral vectors to produce and secrete high levels of human nerve growth factor (NGF). These cells were then grafted to the midthoracic spinal cords of adult rats. Findings were compared to animals that received grafts of nontransduced Schwann cells. Spinal cord lesions were not placed prior to grafting because the primary aim of this study was to examine features of grafted Schwann cell survival, growth, and effects on host axons. In vitro prior to grafting, Schwann cells secreted 1.5 + 0.1 ng human NGF/ml/106 cells/day. Schwann cell transplants readily survived for 2 wk to 1 yr after in vivo placement. Some NGF-transduced grafts slowly increased in size over time compared to nontransduced grafts; the latter remained stable in size. NGF-transduced transplants were densely penetrated by primary sensory nociceptive axons originating from the dorsolateral fasciculus of the spinal cord, whereas control grafts showed significantly fewer penetrating sensory axons. Over time, Schwann cell grafts also became penetrated by TH- and DBH-labeled axons of putative coerulospinal origin, unlike control cell grafts. Ultrastructurally, axons in both graft types were extensively myelinated by Schwann cells. Grafted animals showed no changes in gross locomotor function. In vivo expression of the human NGF transgene was demonstrated for periods of at least 6 m. These findings demonstrate that primary adult Schwann cells 1) can be transduced to secrete augmented levels of neurotrophic factors, 2) survive grafting to the CNS for prolonged time periods, 3) elicit robust growth of host neurotrophin-responsive axons, 4) myelinate CNS axons, and 5) express the transgene for prolonged time periods in vivo. Some grafts slowly enlarge over time, a feature that may be attributable to the propensity of Schwann cells to immortalize after multiple passages. Transduced Schwann cells merit further study as tools for promoting CNS regeneration.

Abstract
Previously we reported that grafts of cells genetically modified to produce human nerve growth factor (hNGF) promoted specific and robust sprouting of spinal sensory, motor, and noradrenergic axons. In the present study we extend these investigations to assess NGF effects on corticospinal motor axons and on functional outcomes after spinal cord injury. Fibroblasts from adult rats were transduced to express human NGF; control cells were not genetically modified. Fibroblasts were then grafted to sites of midthoracic spinal cord dorsal hemisection lesions. Three months later, recipients of NGF-secreting grafts showed deficits on conditioned locomotion over a wire mesh that did not differ in extent from control-lesioned animals. On histological examination, NGF-secreting grafts elicited specific sprouting from spinal primary sensory afferent axons, local motor axons, and putative cerulospinal axons as previously reported, but no specific responses from corticospinal axons. Axons responding to NGF robustly penetrated the grafts but did not exit the grafts to extend to normal innervation territories distal to grafts. Grafted cells continued to express NGF protein through the experimental period of the study. These findings indicate that 1) spinal cord axons show directionally sensitive growth responses to neurotrophic factors, 2) growth of axons responding to a neurotrophic factor beyond an injury site and back to their natural target regions will likely require delivery of concentration gradients of neurotrophic factors toward the target, 3) corticospinal axons do not grow toward a cellular source of NGF, and 4) functional impairments are not improved by strictly local sprouting response of nonmotor systems.

Abstract
In breast cancer research S100A4-positive tumour-associated stromal cells are assumed as primary source of Tenascin C (TNC) in the metastatic environment. Aim of the present study was to isolate and characterize S100A4/TNC positive stromal canine mammary tumour (CMT) cells. Cells grown as scaffold-free spheroids were investigated for S100A4, TNC, and proliferative activity under 1.8% DMSO stimulation by means of Western blot and immunohistochemistry. DMSO is a commonly used drug solvent despite well-known side effects on cells including TNC expression. DMSO did not affect proliferation, but TNC was significantly reduced under DMSO exposure for 7 and 14 days, whereby for S100A4 a reducing effect was only observed after 14 days. Without DMSO, cells stably expressed TNC and S100A4 which makes them suitable to be used in experimental approaches requiring S100A4/TNC expressing CMT stromal cells. Results show that 1.8% DMSO should not be used as solvent for experiments concerning TNC/S100A4 expression.

Abstract
The influence of short term (7-day) exposure of male rats to the brominated flame retardant hexabromocyclododecane (HBCD) was studied by investigation of the liver proteome, both in euthyroid and hypothyroid rats and by comparing results with general data on animal physiology and thyroid hormone, leptin, insulin and gonadotropin concentrations determined in parallel. Proteome analysis of liver tissue by two-dimensional fluorescence difference gel electrophoresis (2D-DIGE) revealed that only small protein pattern changes were induced by exposure in males, on just a few proteins with different functions and not involved in pathways in common. This is in contrast to previous findings in similarly exposed eu- and hypothyroid female rats, where general metabolic pathways had been shown to be affected. The largest gender-dependent effects concerned basal concentrations of liver proteins already in control and hypothyroid animals, involving mainly the pathways which were also differently affected by HBCD exposure. Among them were differences in lipid metabolism, which - upon exposure to HBCD - may also be the reason for the considerably higher ratio of γ-HBCD accumulated in white adipose tissue of exposed female rats compared to males. The results further elucidate the already suggested different sensitivity of genders towards HBCD exposure on the protein level, and confirm the need for undertaking toxicological animal experiments in both genders.

Abstract
Male Wistar rats with different thyroid status (eu-, hypothyroid) were exposed to 0, 3 or 30 mg/kg body weight of the flame retardant HBCD for 7 days and obtained data compared with a previous study in females, “Hexabromocyclododecane (HBCD) induced changes in the liver proteome of eu- and hypothyroid female rats” (Miller et al., 2016) [1]. Specifically, proteomic investigation of liver protein patterns obtained by 2D-DIGE was performed and differences between animals groups recorded, based on the factors exposure, thyroid status and gender. All proteins with significantly changed abundance in any of these comparisons were identified by mass spectrometry. General, hormone and proteomic data of both the present and the previous studies are discussed in Miller et al. (2016) [1] and in "Gender specific differences in the liver proteome of rats exposed to hexabromocyclododecane (HBCD)" Miller et al. (2016) [2].

Abstract
Hexabromocyclododecane (HBCD) is a brominated flame retardant known for its low acute toxicity as observed in animal experiments. However, HBCD exposure can affect liver functioning and thyroid hormone (TH) status. As exact mechanisms are unknown and only limited toxicological data exists, a gel-based proteomic approach was undertaken. In a eu- and hypothyroid female rat model, rats were exposed to 3 and 30 mg/kg bw/day HBCD for 7 days via their diet, and exposure was related to a range of canonical endpoints (hormone status, body weight) available for these animals. Alterations in the liver proteome under HBCD exposure were determined in comparison with patterns of control animals, for both thyroid states. This revealed significantly changed abundance of proteins involved in metabolic processes (gluconeogenesis/glycolysis, amino acid metabolism, lipid metabolism), but also in oxidative stress responses, in both euthyroid and hypothyroid rats. The results provide a more detailed picture on the mechanisms involved in these alterations, e.g. at the protein level changes of the proposed influence of HBCD on the lipid metabolism. Present results show that proteomic approaches can provide further mechanistic insights in toxicological studies.

Abstract
During the last years, an antimicrobial protein from the RegIII family has been consistently identified as one of the main up-regulated mRNA transcripts in the pig small intestinal mucosa during different infections such as enterotoxigenic Escherichia coli (ETEC). This transcript has been mainly referred to in the literature as pancreatitis-associated protein (PAP/RegIIIα). However, the identity of this transcript has not been confirmed, and no evidence of its expression at the protein level is available in the literature, because the absence of a specific antibody. In this study, we first unequivocally identified the PAP/RegIII family protein mainly expressed in ETEC infected pig intestine as RegIIIγ by 2D-DIGE and MALDI-TOF/TOF. This shows that the pig differs from species like human and mice in that RegIIIγ (and not RegIIIα) might be the major RegIII isotype during intestinal infection. Immunoblotting analysis with a specifically generated polyclonal rabbit antibody revealed that pig RegIIIγ is expressed throughout the intestinal tract, but most abundantly in the ileum. Although a higher abundance of mRNA was paralleled by higher protein abundance, a lack of linear relationship was found between RegIIIγ mRNA and protein abundances in the jejunal mucosa, the latter most pronounced in the case of natural infection. This may be related to the secretory nature of RegIIIγ. This would mean that the antimicrobial protein RegIIIγ is a good candidate as a non-invasive faecal intestinal health biomarker in swine.

Abstract
House mice (Mus musculus) produce a variable number of major urinary proteins (MUPs), and studies suggest that each individual produces a unique MUP profile that provides a distinctive odor signature controlling individual and kin recognition. This 'barcode hypothesis' requires that MUP urinary profiles show high individual variability within populations and also high individual consistency over time, but tests of these assumptions are lacking. We analyzed urinary MUP profiles of 66 wild-caught house mice from eight populations using isoelectric focusing. We found that MUP profiles of wild male house mice are not individually unique, and though they were highly variable, closer inspection revealed that the variation strongly depended on MUP band type. The prominent ('major) bands were surprisingly homogenous (and hence most MUPs are not polymorphic), but we also found inconspicuous ('minor') bands that were highly variable and therefore potential candidates for individual fingerprints. We also examined changes in urinary MUP profiles of 58 males over time (from 6 to 24 weeks of age), and found that individual MUP profiles and MUP concentration were surprisingly dynamic, and showed significant changes after puberty and during adulthood. Contrary to what we expected, however, the minor bands were the most variable over time, thus no good candidates for individual fingerprints. Although MUP profiles do not provide individual fingerprints, we found that MUP profiles were more similar among siblings than non-kin despite considerable fluctuation. Our findings show that MUP profiles are not highly stable over time, they do not show strong individual clustering, and thus challenge the barcode hypothesis. Within-individual dynamics of MUP profiles indicate a different function of MUPs in individual recognition than previously assumed and advocate an alternative hypothesis ('dynamic changes' hypothesis).

Abstract
Animal production and health (APH) is an important sector in the world economy, representing a large proportion of the budget of all member states in the European Union and in other continents. APH is a highly competitive sector with a strong emphasis on innovation and, albeit with country to country variations, on scientific research. Proteomics (the study of all proteins present in a given tissue or fluid - i.e. the proteome) has an enormous potential when applied to APH. Nevertheless, for a variety of reasons and in contrast to disciplines such as plant sciences or human biomedicine, such potential is only now being tapped. To counter such limited usage, 6 years ago we created a consortium dedicated to the applications of Proteomics to APH, specifically in the form of a Cooperation in Science and Technology (COST) Action, termed FA1002--Proteomics in Farm Animals: www.cost-faproteomics.org. In 4 years, the consortium quickly enlarged to a total of 31 countries in Europe, as well as Israel, Argentina, Australia and New Zealand. This article has a triple purpose. First, we aim to provide clear examples on the applications and benefits of the use of proteomics in all aspects related to APH. Second, we provide insights and possibilities on the new trends and objectives for APH proteomics applications and technologies for the years to come. Finally, we provide an overview and balance of the major activities and accomplishments of the COST Action on Farm Animal Proteomics. These include activities such as the organization of seminars, workshops and major scientific conferences, organization of summer schools, financing Short-Term Scientific Missions (STSMs) and the generation of scientific literature. Overall, the Action has attained all of the proposed objectives and has made considerable difference by putting proteomics on the global map for animal and veterinary researchers in general and by contributing significantly to reduce the East-West and North-South gaps existing in the European farm animal research. Future activities of significance in the field of scientific research, involving members of the action, as well as others, will likely be established in the future.

Abstract
An UDP-activated murein precursor was isolated from Butyribacterium rettgeri after one hour inhibition by D-cycloserine. The compound contains UDP, muramic acid, L-serine, D-glutamic acid and L-ornithine in equimolar amounts. The amino acid sequence of the tripeptide attached to muramic acid is L-Ser-D-Glu-L-Orn as determined by end group analysis and identification of peptides obtained after partial hydrolysis. As shown by the identification of glutamic acid -γ-hydrazid after hydrazinolysis of the compound, ornithine is bound by its α-amino group to the γ-carboxyl group of glutamic acid. The amino acid sequence of the precursor is in agreement with the structure of the corresponding part of the whole murein of Butyribacterium rettgeri, as proposed recently.

Abstract
Proteomics has the potential to elucidate complex patterns of toxic action attributed to its unique holistic a posteriori approach. In the case of toxic compounds for which the mechanism of action is not completely understood, a proteomic approach may provide valuable mechanistic insight. This review provides an overview of currently available proteomic techniques, including examples of their application in toxicological in vivo and in vitro studies. Future perspectives for a wider application of state-of-the-art proteomic techniques in the field of toxicology are discussed. The examples concern experiments with dioxins, polychlorinated biphenyls, and polybrominated diphenyl ethers as model compounds, as they exhibit a plethora of sublethal effects, of which some mechanisms were revealed via successful proteomic studies. Generally, this review shows the added value of including proteomics in a modern tool box for toxicological studies.

Abstract
BACKGROUND Exposure to life stress is known to adversely impact the course of bipolar disorder. Few studies have disentangled the effects of multiple types of stressors on the longitudinal course of bipolar I disorder. This study examines whether severity of chronic stressors and exposure to trauma are prospectively associated with course of illness among bipolar patients. METHOD One hundred and thirty-one participants diagnosed with bipolar I disorder were recruited through treatment centers, support groups and community advertisements. Severity of chronic stressors and exposure to trauma were assessed at study entry with in-person interviews using the Bedford College Life Event and Difficulty Schedule (LEDS). Course of illness was assessed by monthly interviews conducted over the course of 24 months (over 3000 assessments). RESULTS Trauma exposure was related to more severe interpersonal chronic stressors. Multiple regression models provided evidence that severity of overall chronic stressors predicted depressive but not manic symptoms, accounting for 7.5% of explained variance. CONCLUSIONS Overall chronic stressors seem to be an important determinant of depressive symptoms within bipolar disorder, highlighting the importance of studying multiple forms of life stress.

Abstract
Background and aims The incidence of uterine carcinosarcoma and factors associated with its survival are little known and this study helps to address this question for women residing in north-east Scotland. Methods and results Data were collected from women diagnosed with carcinosarcoma of the uterus residing in north-east of Scotland from 1991 to 2009. Kaplan–Meier plots and Cox regression analysis were used for analysis. A total of 43 women were analysed during this period. The median survival was 25 months. The estimated five-year survival for stage I/II disease was 52.5% (95% CI: 30.5–74.5%). The 2-year survival rate for stage III/IV disease was 46% (95% CI: 16–75%). There was an increase in the incidence during this period. Improved survival was seen in early-stage disease (FIGO stages I and II) and in the absence of lymphovascular space invasion (LVSI; p = 0.015). A total of 26% of the women had a history of tamoxifen usage with no effect seen on survival. Multivariate analysis showed that when treatment modality and LVSI were adjusted for FIGO staging, there was no statistical significance in the survival outcomes. Conclusion The incidence of uterine carcinosarcomas is increasing parallel with endometrial carcinomas with no significant effect of tamoxifen on survival.

Abstract
Animals with different health status have been studied in order to extend the knowledge about protein composition of porcine saliva samples and to discover potential salivary markers for systemic disease in porcine production. Clinical examination of animals was performed at farm level where 10 healthy pigs and 10 animals with evident clinical signs of disease were randomly selected. Saliva and blood samples were obtained and afterwards animals were humanely sacrificed to perform a complete necropsy. Levels of two acute phase proteins, haptoglobin and C-reactive protein, were used to identify possible active infections of the animals. Moreover, serological analysis, to the main porcine infectious diseases in the area, was performed. Salivary proteins were separated by two-dimensional gel electrophoresis followed by mass spectrometry for the identification of specific proteins. A total of 58 spots out of 75 were successfully identified by MS, which correspond to 20 unique proteins. Two different approaches were used to perform a statistical comparison of saliva protein patterns from healthy and diseased animals using the relative spot volume (% spot volume/total volume of all spot in the gel, approach "A") or taking also into account the total protein content of each saliva sample (μg of spot/mL of saliva, approach "B"). Both analyses showed three proteins in common that are differentially regulated between states. However, approach B was selected for biomarker searching since it gave an estimation of protein concentration and showed differential expression of proteins between both health states in a total of 10 proteins, which were up-regulated in disease. Mass spectrometric analysis identified those proteins as salivary lipocalin, lipocalin 1, double headed protease inhibitor protein, adenosine deaminase, haptoglobin, albumin fragments, S100-A8, S100-A9, S100-A12 and pancreatic alpha amylase. These proteins could be considered as potential salivary markers of disease.

Abstract
The objective of this study was to investigate how weight-loss program would alter the proteome of the serum of Beagle dogs. For this purpose, serum samples from 5 Beagle dogs, before and after weight loss, were analyzed using 2-dimensional electrophoresis. Protein profiles of all samples were obtained, divided into 2 classes (obese and lean), and compared using specific 2-dimensional software, giving a total of 144 spot matches. Statistical analysis revealed 3 spot matches whose expressions were modulated in response to weight loss: 2 protein spots were upregulated and 1 protein spot was downregulated in the obese state in comparison with the lean state of the dogs. Mass spectrometric identification of differentially regulated spots revealed that these protein spots corresponded to retinol-binding protein 4, clusterin precursor, and α-1 antitrypsin, respectively, which could be considered potential markers of obesity and obesity-related disease processes in dogs.

Abstract
Aim of this study was to determine the intrauterine activity of matrix metalloproteinases (MMP)-2 and -9 after cessation of the local effect of progesterone. For this purpose, pregnancy was terminated in 10 bitches at mid-gestation with the progesterone receptor antagonist aglepristone (10 mg/kg body weight, sc, Alizine®; Virbac, France) at two subsequent days (group IRA = induced resorption/abortion). The IRA group was divided into two subgroups (Group I, n = 5, days 25-35 of pregnancy; group II, n = 5, days 36-45). Five further bitches were introduced with beginning abortion (group SRA = spontaneous resorption/abortion). Seven healthy bitches between day 25 and 45 of gestation served as controls. After ovariohysterectomy at the end of abortion and between days 25 and 45 of gestation, respectively, the distribution and activity of collagenases were investigated by immunohistochemistry and gelatin zymography. At placental sites, MMP-2 activity in the endometrium was significantly lower in IRA groups than in the SRA group (33.7 ± 11.8% and 39.3 ± 5.4% vs 52.2 ± 10.2%, p < 0.05); however, MMP-2 expression was lowest in the control group (control: 21.4 ± 6.3%; p < 0.01) and similarly in the myometrium (controls: 13.1 ± 2.5%; p < 0.05). MMP-9 activity was also lower in the endometrium and myometrium of the control group in comparison to SRA and IRA groups (11.8 ± 3.2%; p < 0.01 and 28.4 ± 32.8%; p < 0.05). At interplacental sites, the amount of active collagenases in the myometrium was significantly lower in the control group. It is concluded that the blockade of the biological progesterone effect was associated with an increase in activity of both collagenases.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) has an impact on patients' quality of life. Treatment of HS is generally unsatisfactory, thus new treatments are needed. OBJECTIVES To test the efficacy of adalimumab in HS. METHODS This was a prospective, randomized, double-blinded, placebo-controlled, two-centre clinical trial conducted in Denmark. Inclusion criteria were age above 18 years and a clinical diagnosis of moderate to severe HS defined as Hurley stage II or III for at least 6 months. The patients were randomized 1:2 (placebo/active). Actively treated patients received adalimumab 80 mg subcutaneously (s.c.) at baseline followed by 40 mg s.c. every other week for 12 weeks. Placebo-treated patients received identical-looking injections with no active ingredient. The medicine was dispensed in sequentially numbered computer-randomized containers. Participants, care givers and those assessing the outcomes were blinded to group assignment. The primary efficacy endpoints were changes in the HS scores (Sartorius and Hurley scoring systems). Secondary efficacy endpoints included changes in pain (visual analogue scale), days with lesions and Dermatology Life Quality Index, and evaluation of scarring. Recruitment was terminated early due to expiry date of trial medication. RESULTS Twenty-one patients were included, of whom 15 received adalimumab and six received placebo. All participants were analysed according to the intention to treat principle. A significant reduction was seen in Sartorius score after 6 weeks and an almost significant reduction was seen after 12 weeks of active treatment (-10·7 vs. 7·5, P = 0·024 and -11·3 vs. 5·8, P = 0·07) when compared with the placebo group. CONCLUSIONS A significant reduction in HS severity was gained after 6 weeks. No long-term curative effect was uniformly seen.

Abstract
OBJECTIVE Incomplete resection of the epileptogenic zone (EZ) is the most important predictor of poor outcome after resective surgery for intractable epilepsy. We analyzed the contribution of preoperative and perioperative variables including MRI and EEG data as predictors of seizure-free (SF) outcome after incomplete resection. METHODS We retrospectively reviewed patients <18 years of age with incomplete resection for epilepsy with 2 years of follow-up. Fourteen preoperative and perioperative variables were compared in SF and non-SF (NSF) patients. We compared lesional patients, categorized by reason for incompleteness, to lesional patients with complete resection. We analyzed for effect of complete EEG resection on SF outcome in patients with incompletely resected MRI lesions and vice versa. RESULTS Eighty-three patients with incomplete resection were included with 41% becoming SF. Forty-eight lesional patients with complete resection were included. Thirty-eight percent (57/151) of patients with incomplete resection and 34% (47/138) with complete resection were excluded secondary to lack of follow-up or incomplete records. Contiguous MRI lesions were predictive of seizure freedom after incomplete resection. Fifty-seven percent of patients incomplete by MRI alone, 52% incomplete by EEG alone, and 24% incomplete by both became SF compared to 77% of patients with complete resection (p = 0.0005). CONCLUSIONS Complete resection of the MRI- and EEG-defined EZ is the best predictor of seizure freedom, though patients incomplete by EEG or MRI alone have better outcome compared to patients incomplete by both. More than one-third of patients with incomplete resection become SF, with contiguous MRI lesions a predictor of SF outcome.

Abstract
Studies correlating the production of infectious adenovirus (types 5 and 7) and the progression of the stages of virus-induced cytologic change in HeLa cells are presented. The results reveal a close relationship between the development of the characteristic nuclear changes and adenovirus synthesis. They suggest that cells manifesting the first stages of nuclear change, characterized by the appearance of eosinophilic, Feulgen-negative inclusions, contain little or no mature infectious virus, whereas cells in the later stages, with Feulgen-positive and basophilic inclusions, contain relatively large amounts.

Abstract
The aim of the present study was to demonstrate the presence and localization of MMP-2 and -9 by means of RT-PCR and immunohistochemistry (IHC) within the canine uterus from the pre-implantation stage until mid-gestation and to determine MMP-2 and -9 activities by means of zymography. For this purpose, samples of the uterus and salpinx from bitches were obtained after ovariohysterectomy. Pre-implantation stages (5-12 days after mating, n = 11) were determined by verifying embryos after flushing the uterus. Further groups were determined as implantation (15-19 days after mating, n = 9), post-implantation (20-30 days after mating, n = 9) and placental stages (30-45 days after mating, n = 3). A non-pregnant group (17-30 days after mating, n = 4) served as control. MMP-2 and -9 positive cells were detected in all specimens from pregnant and nonpregnant bitches, however, with different distributions. MMP-2 was present in endothelium and smooth muscles of blood vessels and the myometrium of pregnant and nonpregnant bitches, additionally in the surface epithelium of the oviduct. The latter also stained positive for MMP-9. During placentation, MMP-2 was detected mainly in fetal blood vessels and trophoblastic cells. Higher MMP-2 activity was observed in the endometrium and myometrium of all pregnant groups compared with the nonpregnant group (p < 0.05). The pregnant groups did not differ significantly from each other (p > 0.05). MMP-9 was present in blood vessels, smooth muscle cells and epithelia, such as maternal surface epithelial cells, uterine crypts and glands. During placentation, the deep uterine glands and the epithelium of the glandular chambers were immunoreactive to MMP-9. Highest MMP-9 activities were reached in the endometrium of the pre-implantation group (23.2% of total MMP-9) and placental parts (33.3%).

Abstract
Vascular endothelial growth factor (VEGF) stimulates endothelial cell proliferation and has a pivotal role in tumour angiogenesis. The expression of VEGF and its receptors VEGFR-1 and VEGFR-2 was examined immunohistochemically in 43 specimens of canine lymphoma and in six normal lymph nodes. Western blotting and reverse transcriptase polymerase chain reaction (RT-PCR) were performed to detect VEGF protein and mRNA, respectively. VEGF protein was expressed by 60% of the tumours with diffuse cytoplasmic labelling of the neoplastic cells. Endothelial cells, macrophages and plasma cells were also immunolabelled. VEGFR-1 was expressed by variable numbers of neoplastic cells in 54% of lymphoma specimens. VEGFR-1 was also expressed by macrophages, plasma cells, reticulum cells, and vascular endothelial cells. Macrophages and lymphocytes in germinal centres of normal lymph nodes were also immunoreactive with anti-VEGF and VEGFR-1. Most tumours did not express VEGFR-2 but in 7% of sections there was focal labelling of neoplastic and endothelial cells, with a cytoplasmic and perinuclear pattern. The observed variability in expression of VEGF and its receptors probably relates to the fact that lymphoma is a heterogeneous lymphoproliferative tumour. Individual differences in VEGF and VEGFR expression must be taken into account when VEGF and VEGFR-targeted approaches for anti-angiogenic therapy are considered in dogs.

Abstract
AbstractIntroduction:Within the field of otorhinolaryngology, interest in facial plastic surgery has grown significantly in recent years. There is a lack of evidence in the literature documenting this interest in the British Isles.Materials and methods:572 questionnaires were mailed to all members of the British Association of Otolaryngologists, Head and Neck Surgeons and to members of the Irish Otolaryngological Society.Results:Our response rate was 68 per cent. One-third of respondents were performing facial plastic procedures regularly, most commonly otoplasty (80 per cent), rhinoplasty (74 per cent) and facial flaps (28 per cent). Two-thirds of respondents had attended supplementary courses in facial plastic surgery, and 65 per cent would like facial plastic surgery to compose one-third of their daily practice.Discussion:Facial plastic surgery has become a significant part of the otorhinolaryngologists' practice. They are now offering a wider variety of procedures in the area. This is the first paper to document this interest in the United Kingdom and Ireland.

Abstract
INTRODUCTION Insulin-like growth factor (IGF) possesses mitogenic properties promoting cellular proliferation and inhibiting cellular apoptosis. Reported evidence suggests that cancer (non-oral) is associated with high circulating levels of IGF-1 and low levels of IGFBP-3. AIMS This study measured circulating levels of IFG-1 and IGFBPs -1, -2 and -3 in oral cancer patients. METHODOLOGY Blood was collected from surgical patients and controls. Samples were assayed for IGF-1 and IGFBPs -1, -2, -3, using commercially available enzyme-linked immunosorbant assays (ELISA; R&D Systems Europe, Oxon, UK). RESULTS Twenty-seven oral cancer and 31 age- and sex-matched patients were recruited. Mean IGF-1 and IGFBP-3 levels were significantly lower in cancer patients than controls (85.3 ng/ml and 2008 ng/ml versus 191 ng/ml and 2935 ng/ml, P<0.001). In contrast, levels of IGFBPs 1 and 2 were significantly higher in cancer patients than in controls. No significant association was demonstrated with tumour size or nodal metastases. DISCUSSION This study has shown that in contrast to other cancers, circulating levels of IGF-1 and IGFBP-3 may both be lowered in patients with head and neck cancer.

Abstract
AbstractEuropean chub Leuciscus cephalus collected from five localities in the lowland and subalpine regions of Austria were analysed for oestrogenic effects of endocrine-disrupting chemicals and the presence of the plerocercoid of the tapeworm Ligula intestinalis. Of 1494 chub analysed, only seven (six males, one female) were found to be infected with single, but large plerocercoids up to 15 cm in length. Ligula-infected fish showed comparatively immature gonads, as demonstrated by the gonadosomatic index and gamete developmental stages. Plasma levels of the egg precursor protein vitellogenin also showed concentrations ranging below the detection limit. The present results indicate that chub infected with L. intestinalis and exposed to exogenous oestrogenic compounds can result in reduced gonadal maturation and produce false oestrogen-positive diagnoses in male fish. For plasma vitellogenin levels, L. intestinalis infections can result in false oestrogen-negative diagnoses in male and female fish.

Abstract
The health status of a 4-year-old female, dd-haplotype miniature pig deteriorated rapidly, so the animal finally had to be euthanized because of poor clinical condition. Necropsy revealed a massive leukocytic infiltration in the parenchymatous organs of the abdominal cavity. On hematologic cell counting, severe leukocytosis (69.3 x 10(9) cells/liter) and high-grade basophilia (6.9 x 10(9) cells/liter) were evident. Cytologic examination, as well as analysis of expression of leukocyte differentiation antigens by means of flow cytometry, classified blasts, which accounted for about 22% of leukocytes, as biphenotypic cells co-expressing the myeloid marker SWC3 (CD172a) and the lymphoid markers CD5 and CD25. Hematologic features resembled those seen in humans with chronic myeloid leukemia at blast phase.

Abstract
Farming of fur animals represents an important income in Estonia. Even though Trichinella worms does not induce a symptomatic disease in carnivores, the carcasses of skinned animals can increase the biomass of the parasite in the environment, if they are not properly destroyed. The aim of the present survey was to study the prevalence of Trichinella worms in farmed fur animals of Estonia. Of 281 muscle samples from blue foxes (Alopex lagopus), silver foxes (Vulpes vulpes fulva), minks (Mustela vison) and raccoon dogs (Nyctereutes procyonoides), which were collected in eight farms, Trichinella larvae have been detected in 21 animals (8%) from two farms by HCl-pepsin digestion. The highest number of larvae per gram of muscle was found in the front limb muscles. Larvae of the 21 isolates have been identified as Trichinella britovi or Trichinella nativa by a multiplex-PCR analysis.

Abstract
The targets of the Structural GenomiX (SGX) bacterial genomics project were proteins conserved in multiple prokaryotic organisms with no obvious sequence homolog in the Protein Data Bank of known structures. The outcome of this work was 80 structures, covering 60 unique sequences and 49 different genes. Experimental phase determination from proteins incorporating Se-Met was carried out for 45 structures with most of the remainder solved by molecular replacement using members of the experimentally phased set as search models. An automated tool was developed to deposit these structures in the Protein Data Bank, along with the associated X-ray diffraction data (including refined experimental phases) and experimentally confirmed sequences. BLAST comparisons of the SGX structures with structures that had appeared in the Protein Data Bank over the intervening 3.5 years since the SGX target list had been compiled identified homologs for 49 of the 60 unique sequences represented by the SGX structures. This result indicates that, for bacterial structures that are relatively easy to express, purify, and crystallize, the structural coverage of gene space is proceeding rapidly. More distant sequence-structure relationships between the SGX and PDB structures were investigated using PDB-BLAST and Combinatorial Extension (CE). Only one structure, SufD, has a truly unique topology compared to all folds in the PDB.

Abstract
Periglandular arrangement of myofibroblasts, associated with the deposition of extracellular matrix (ECM), is a cardinal feature of endometrosis in mares. We hypothesized that a disturbance in the expression of matrix degrading enzymes such as matrix metalloproteinases (MMP's) and matrix cross-linking proteins might lead to an imbalance in deposition and degradation of extracellular matrix components and thereby accentuate degeneration. Therefore, distributions of MMP-2, capable of collagen IV and laminin degradation, and tissue transglutaminase (TG2), a cross-linker of extracellular matrix proteins, were investigated by means of immunohistochemistry on uterine biopsies of healthy mares and animals with endometrosis. It was illustrated that both proteins were present in fibrotic regions of affected endometria, and that they were in most cases colocalized. Periglandular MMP-2 expression was significantly associated with dilated and fibrotic uterine glands. Furthermore, MMP-2 and TG 2 were demonstrated in the stratum compactum of healthy and endometrotic endometria. Gelatin zymography proved that active and inactive pro-form of MMP-2 were present in all examined samples with significantly higher amounts of total and active MMP-2 in affected endometria. TG 2-activity, determined by an in situ assay, was found in cases of severe periglandular fibrosis. We suggest that both enzymes play a major role in changes that occur in ECM homeostasis in endometrial fibrotic regions.

Abstract
Two-dimensional electrophoresis is usually run on fully reduced samples. Under these conditions even covalently bound oligomers are dissociated and individual polypeptide chains may be fully unfolded by both, urea and SDS, which maximizes the number of resolved components and allows their pI and M(r) to be most accurately evaluated. However, various electrophoretic protocols for protein structure investigation require a combination of steps under varying redox conditions. We review here some of the applications of these procedures. We also present some original data about a few related samples -- serum from four species: Homo sapiens, Mus musculus, Rattus norvegicus, Bos taurus -- which we run under fully unreduced and fully reduced conditions as well as with reduction between first and second dimension. We demonstrate that in many cases the unreduced proteins migrate with a better resolution than reduced proteins, mostly in the crowded 'alpha-globulin' area of pI 4.5-6 and M(r) 50-70 kDa.
