Abstract
A perimetastatic capsule is a strong positive prognostic factor in liver metastases, but its origin remains unclear. Here, we systematically quantify the capsule's extent and cellular composition in 263 patients with colorectal cancer liver metastases to investigate its clinical significance and origin. We show that survival improves proportionally with increasing encapsulation and decreasing tumor-hepatocyte contact. Immunostaining reveals the gradual zonation of the capsule, transitioning from benign-like NGFRhigh stroma at the liver edge to FAPhigh stroma towards the tumor. Encapsulation correlates with decreased tumor viability and preoperative chemotherapy. In mice, chemotherapy and tumor cell ablation induce capsule formation. Our results suggest that encapsulation develops where tumor invasion into the liver plates stalls, representing a reparative process rather than tumor-induced desmoplasia. We propose a model of metastases growth, where the efficient tumor colonization of the liver parenchyma and a reparative liver injury reaction are opposing determinants of metastasis aggressiveness.

Abstract
Critically ill COVID-19 patients with pleural effusion experience longer hospitalization, multisystem inflammatory syndrome, and higher rates of mortality. Generally, pleural effusion can serve as a diagnostic value to differentiate cytokine levels. This study aimed to evaluate the pleural effusions of COVID-19 deceased patients for 182 protein markers. Olink® Inflammation and Organ Damage panels were used to determine the level of 184 protein markers, e.g., ADA, BTC, CA12, CAPG, CD40, CDCP1, CXCL9, ENTPD2, Flt3L, IL-6, IL-8, LRP1, OSM, PD-L1, PTN, STX8, and VEGFA, which were raised significantly in COVID-19 deceased patients, showing over-stimulation of the immune system and ravaging cytokine storm. The rises of DPP6 and EDIL3 also indicate damage caused to arterial and cardiovascular organs. Overall, this study confirms the elevated levels of CA12, CD40, IL-6, IL-8, PD-L1, and VEGFA, proposing their potential either as biomarkers for the severity and prognosis of the disease or as targets for therapy. Particularly, this study reports upregulated ADA, BTC, DPP6, EDIL3, LIF, ENTPD2, Flt3L, and LRP1 in severe COVID-19 patients for the first time. Pearson's correlation coefficient analysis indicates the involvement of JAK/STAT pathways as a core regulator of hyperinflammation in deceased COVID-19 patients, suggesting the application of JAK inhibitors as a potential efficient treatment.

Abstract
The first consensus guidelines for scoring the histopathological growth patterns (HGPs) of liver metastases were established in 2017. Since then, numerous studies have applied these guidelines, have further substantiated the potential clinical value of the HGPs in patients with liver metastases from various tumour types and are starting to shed light on the biology of the distinct HGPs. In the present guidelines, we give an overview of these studies, discuss novel strategies for predicting the HGPs of liver metastases, such as deep-learning algorithms for whole-slide histopathology images and medical imaging, and highlight liver metastasis animal models that exhibit features of the different HGPs. Based on a pooled analysis of large cohorts of patients with liver-metastatic colorectal cancer, we propose a new cut-off to categorise patients according to the HGPs. An up-to-date standard method for HGP assessment within liver metastases is also presented with the aim of incorporating HGPs into the decision-making processes surrounding the treatment of patients with liver-metastatic cancer. Finally, we propose hypotheses on the cellular and molecular mechanisms that drive the biology of the different HGPs, opening some exciting preclinical and clinical research perspectives.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is the most common type of pancreatic cancer. PDAC has a dismal prognosis and an inherent resistance to cytostatic drugs. The lack of reliable experimental models is a severe limitation for drug development targeting PDAC. We have employed a whole tissue ex vivo culture model to explore the effect of redox-modulation by sodium selenite on the viability and growth of PDAC. Drug-resistant tumors are more vulnerable to redox-active selenium compounds because of high metabolic activity and redox imbalance. Sodium selenite efficiently and specifically reduced PDAC cell viability (p <0.02) (n=8) and decreased viable de novo tumor cell outgrowth (p<0.05) while preserving non-neoplastic tissues. Major cellular responses (damaged tumor cells > 90%, tumor regression grades III-IV according to Evans) were observed for sodium selenite concentrations between 15-30 µM. Moreover, selenium levels used in this study were significantly below the previously reported maximum tolerated dose for humans. Transcriptome data analysis revealed decreased expression of genes known to drive PDAC growth and metastatic potential (CEMIP, DDR2, PLOD2, P4HA1) while the cell death-inducing genes (ATF3, ACHE) were significantly upregulated (p<0.0001). In conclusion, we report that sodium selenite has an extraordinary efficacy and specificity against drug-resistant pancreatic cancer in an organotypic slice culture model. Our ex vivo organotypic tissue slice culture model can be used to test a variety of drug candidates for swift and reliable drug responses to individual PDAC cases.

Abstract
PDAC cells in the duodenal epithelium mimic intestinal cells and co-opt the basement membrane. Intramucosal PDAC location is strongly coupled to the classical phenotype and to intestinal traits. Intratumoral heterogeneity is linked to specific tissue compartments, which shape phenotype plasticity of PDAC cells.
Introduction Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive solid tumors. Based on transcriptomic classifiers, basal-like and classical PDAC subtypes have been defined that differ in prognosis. Cells of both subtypes can coexist in individual tumors; however, the contribution of either clonal heterogeneity or microenvironmental cues to subtype heterogeneity is unclear. Here, we report the spatial tumor phenotype dynamics in a cohort of patients in whom PDAC infiltrated the duodenal wall, and identify the duodenal epithelium as a distinct PDAC microniche. Materials and methods We used serial multiplex quantitative immunohistochemistry (smq-IHC) for 24 proteins to phenotypically chart PDAC tumor cells in patients whose tumors infiltrated the duodenal epithelium. Additionally, we used a genetically engineered mouse model to study the PDAC cell phenotype in the small intestinal epithelium in a controlled genetic background. Result We show that pancreatic cancer cells revert to non-destructive growth upon integration into the duodenal epithelium, where they adopt traits of intestinal cell differentiation, associated with phenotypical stabilization of the classical subtype. The integrated tumor cells replace epithelial cells in an adenoma-like manner, as opposed to invasive growth in the submucosa. Finally, we show that this phenomenon is shared between species, by confirming duodenal integration and phenotypic switching in a genetic PDAC mouse model. Discussion Our results identify the duodenal epithelium as a distinct PDAC microniche and tightly link microenvironmental cue to cancer transcriptional subtypes. The phenomenon of “intestinal mimicry” provides a unique opportunity for the systematic investigation of microenvironmental influences on pancreatic cancer plasticity.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma is a devastating disease with poor outcome, generally characterized by an excessive stroma component. The purpose of this study was to develop a simple and reproducible in vitro 3D-assay employing the main constituents of pancreatic ductal adenocarcinoma, namely pancreatic stellate and cancer cells. METHOD A spheroid assay, directly co-culturing human pancreatic stellate cells with human pancreatic tumour cells in 3D was established and characterized by electron microscopy, immunohistochemistry and real-time RT-PCR. In order to facilitate the cell type-specific crosstalk analysis by real-time RT-PCR, we developed a novel in vitro 3D co-culture model, where the participating cell types were from different species, human and mouse, respectively. Using species-specific PCR primers, we were able to investigate the crosstalk between stromal and cancer cells without previous cell separation and sorting. RESULTS We found clear evidence for mutual influence, such as increased proliferation and a shift towards a more mesenchymal phenotype in cancer cells and an activation of pancreatic stellate cells towards the myofibroblast phenotype. Using a heterospecies approach, which we coined virtual sorting, confirmed the findings we made initially in the human-human spheroids. CONCLUSIONS We developed and characterized different easy to set up 3D models to investigate the crosstalk between cancer and stroma cells for pancreatic cancer.

Abstract
Background Colorectal cancer liver metastases (CRLM) grow in distinct histological patterns that have been associated with outcome after surgical resection. We conducted a systematic review to evaluate the frequency of different CRLM growth patterns and their impact on prognosis. Methods We searched Embase and MEDLINE databases from inception to 1 December 2017 to identify studies that reported CRLM growth pattern histopathology, their frequencies, and/or data related to outcome. Results We included a total of 23 studies (2432 patients with CRLM) published between 1991 and 2017. There were variations in the terminology used to describe the growth patterns as well as in their histopathological definitions. A 'desmoplastic' pattern was most frequently considered, followed by 'pushing' and 'replacement' patterns. Data supported the presence of both intralesional and interlesional heterogeneity. There were no differences in growth pattern distribution stratified by chemotherapy. While heterogeneity of histopathology assessment precluded formal meta-analysis, the majority of articles found favourable outcomes for desmoplastic and unfavourable outcomes for replacement CRLM, independently of when the study was conducted. Conclusions The results suggest that CRLM growth patterns may have prognostic potential and that they may be considered for standardised routine histopathological reporting. Further understanding of the different growth patterns may provide important insights into the biological mechanisms that underlie metastatic growth in the liver.

Abstract
BACKGROUND & AIMS Adenocarcinomas of the pancreatobiliary system are currently classified by their primary anatomical location. In particular, the pathological diagnosis of intrahepatic cholangiocarcinoma is still considered as a diagnosis of exclusion of metastatic adenocarcinoma. Periampullary cancers have been previously classified according to the histological type of differentiation (pancreatobiliary, intestinal), but overlapping morphological features hinder their differential diagnosis. We performed an integrative immunohistochemical analysis of pancreato-biliary tumors to improve their diagnosis and prediction of outcome. METHODS This was a retrospective observational cohort study on patients with adenocarcinoma of the pancreatobiliary system who underwent diagnostic core needle biopsy or surgical resection at a tertiary referral center. 409 tumor samples were analyzed with up to 27 conventional antibodies used in diagnostic pathology. Immunohistochemical scoring system was the percentage of stained tumor cells. Bioinformatic analysis, internal validation, and survival analysis were performed. RESULTS Hierarchical clustering and differential expression analysis identified three immunohistochemical tumor types (extrahepatic pancreatobiliary, intestinal, and intrahepatic cholangiocarcinoma) and the discriminant markers between them. Among patients who underwent surgical resection of their primary tumor with curative intent, the intestinal type showed an adjusted hazard ratio of 0.19 for overall survival (95% confidence interval 0.05-0.72; p value = 0.014) compared to the extrahepatic pancreatobiliary type. CONCLUSIONS Integrative immunohistochemical classification of adenocarcinomas of the pancreatobiliary system results in a characteristic immunohistochemical profile for intrahepatic cholangiocarcinoma and intestinal type adenocarcinoma, which helps in distinguishing them from metastatic and pancreatobiliary type adenocarcinoma, respectively. A diagnostic immunohistochemical panel and additional extended panels of discriminant markers are proposed as guidance for their pathological diagnosis.

Abstract
We report the first successful transplantation of cryopreserved ovarian cortical tissue into heavily irradiated tissues in a patient who had received sterilizing pelvic radiotherapy (54 Gy) and 40 weeks of intensive high-dose chemotherapy for the treatment of Ewing’s sarcoma 14 years earlier. Repeated transplantation procedures were required to obtain fully functional follicular development. Enlargement of the transplants over time and increase of the size of the uterus were demonstrated on sequential ultrasonographic examinations. Eggs of good quality that could be fertilized in vitro were obtained only after a substantial incremental increase of the amount of ovarian tissue transplanted. Single embryo replacement resulted in a normal pregnancy and the birth of a healthy child by cesarean section at full-term. No neonatal or maternal postoperative complications occurred. Women facing high-dose pelvic radiotherapy should not be systematically excluded from fertility preservation options, as is currently the trend.

Abstract
BACKGROUND Tracheal tumours can be surgically resected but most are an inoperable size at the time of diagnosis; therefore, new therapeutic options are needed. We report the clinical transplantation of the tracheobronchial airway with a stem-cell-seeded bioartificial nanocomposite. METHODS A 36-year-old male patient, previously treated with debulking surgery and radiation therapy, presented with recurrent primary cancer of the distal trachea and main bronchi. After complete tumour resection, the airway was replaced with a tailored bioartificial nanocomposite previously seeded with autologous bone-marrow mononuclear cells via a bioreactor for 36 h. Postoperative granulocyte colony-stimulating factor filgrastim (10 μg/kg) and epoetin beta (40,000 UI) were given over 14 days. We undertook flow cytometry, scanning electron microscopy, confocal microscopy epigenetics, multiplex, miRNA, and gene expression analyses. FINDINGS We noted an extracellular matrix-like coating and proliferating cells including a CD105+ subpopulation in the scaffold after the reseeding and bioreactor process. There were no major complications, and the patient was asymptomatic and tumour free 5 months after transplantation. The bioartificial nanocomposite has patent anastomoses, lined with a vascularised neomucosa, and was partly covered by nearly healthy epithelium. Postoperatively, we detected a mobilisation of peripheral cells displaying increased mesenchymal stromal cell phenotype, and upregulation of epoetin receptors, antiapoptotic genes, and miR-34 and miR-449 biomarkers. These findings, together with increased levels of regenerative-associated plasma factors, strongly suggest stem-cell homing and cell-mediated wound repair, extracellular matrix remodelling, and neovascularisation of the graft. INTERPRETATION Tailor-made bioartificial scaffolds can be used to replace complex airway defects. The bioreactor reseeding process and pharmacological-induced site-specific and graft-specific regeneration and tissue protection are key factors for successful clinical outcome.

Abstract
The authors report on a case of melanocytoma surgically removed from the craniocervical meninges of a 59-year-old man. Although the excision had been incomplete, the patient showed a disease-free course extending well over ten years. On histology, the tumor consisted of moderately cellular arrays of spindle-shaped melanocytes with a vaguely angiocentric whorling tendency, and without evidence of infiltrative growth. Electron microscopy identified tumor cells as ones bearing dendritic processes with complex melanosomes. The latter showed histochemical properties of melanosomal melanin, as well as immunoreactivity for the melanosome-associated markers HMB-45, and MELAN-A. Hallmarks of meningial differentiation were, at the same time, absent. The MIB-1 proliferation rate of the lesion, as assessed in a simultaneous testing of a panel including primary and metastatic central nervous system melanomas, as well as a uveal melanoma remained inferior to 1.5 percent. The data presented and a critical review of the literature suggest that meningeal melanocytoma is a mostly benign nevus-like lesion of neural crest cells with a very limited, although not discountable, margin for aggressive growth.

Abstract
Five patients suffering from idiopathic cricopharyngeal dysfunction (without Zenker's diverticulum) were treated surgically. Together with cricopharyngeomyotomy biopsies were taken at the level of the cricopharyngeus. Histological, enzyme hystochemical and electronmicroscopic examinations were performed on all patients. In two cases the histology revealed myogen dystrophy (presence of necrosis, myophagocytosis, abnormal fiber structure, basophilic fibers, fibrosis, mild cellular reaction and predominancy of fiber type I). Since the complete patient evaluation (clinical features, electromyography, serum creatinin phosphokinase level, etc.) could rule out any general, muscle disorders, the cause of the idiopathic pharyngeal dysfunction must have been in these two cases an isolated myogen dystrophy of the cricopharyngeus.

Abstract
Thirteen surgically removed, epoxy resin (Durcupan ACM or Epon 812)-embedded human brain tumors were examined for glial fibrillary acidic protein (GFAP) content in semithin and ultrathin sections with the immunogold-silver staining method. Mild aldehyde fixation and the hydrophobic resin embedding did not interfere with the antigenicity, since silver intensification of the immunogold marker provided excellent visualization of the reaction on both light microscopic and ultrastructural levels. The GFAP reaction was usually localized on the glial intermediate filament bundles, usually correlating well with the amount of filaments. The unstained filamental regions of two ependymomas might correspond to the vimentin expression revealed by double labeling in semithin sections. Occasional GFAP immunopositivity without filamental appearance was observed in one of the oligodendrogliomas, as patchy electron-dense cytoplasmic corpuscules, in Rosenthal fibers and in some mainly necrobiotic tumor cells, reflecting a possible connection with glial filaments.

Abstract
Double and triple immunocytochemical detection methods for routine use in histopathology were investigated. For double immunostaining, the combinations of immunogold-silver staining (IGSS, black) with an immunoperoxidase method (3-amino-9-ethylcarbazole, red-brown) or with an immunoalkaline phosphatase method (Fast Red TR, red) proved very useful. These were followed by a Haematoxylin counterstain. An alternative approach using immunoperoxidase (red-brown) and immunoalkaline phosphatase (Fast Blue, BB, blue) methods was also successful, particularly for frozen sections of unfixed tissue and for the establishment of intermediate filament coexpression in tumours. The coexistence of desmin with vimentin in rhabdomyosarcoma, and of glial fibrillary acidic protein with vimentin in ependymoma, could be demonstrated directly by means of non-crossreacting murine and rabbit antibodies in the above combinations. The black (IGSS), red-brown (immunoperoxidase) and blue (immunoalkaline phosphatase) colours gave excellent contrast in triple immunostaining. The side-by-side demonstration of helper and suppressor T lymphocytes during renal allograft rejection, of kappa and lambda light chains in B-immunoblastic lymphoma, and of T and B lymphocyte populations in non-Hodgkin's lymphomas provided immediate information on the topography and cellular organization of the tissues.

Abstract
The effect of tiacrilast, a mast cell mediator-release inhibitor, was studied in dinitrofluorobenzene-induced allergic and croton oil- or dimethyl sulfoxide-induced irritant murine contact dermatitis. At 1% concentration, the compound significantly reduced the ear swelling in both allergic and irritant dermatitis and preserved the mast cell architecture on histopathology. These findings suggest that mast cells participate in the elicitation of murine contact dermatitis.

Abstract
Imprints of haematoxilin-eosin and Giemsa-stained, 33 surgically removed different intracranial tumors were examined. In case of sufficient number of cells and adequate clinical data, the cytological examination was suitable to quick intraoperative diagnosis in majority of cases. Its demonstration on GFAP smear facilitates the diagnosing of gliomas.

Abstract
A new monoclonal antibody, M1-8, that recognizes murine interdigitating cells (IDC) and Langerhans cells was obtained from a hybridoma prepared by fusion of SP2/0 mouse myeloma cells with splenic cells of rats immunized with IDC-rich cell suspension obtained from lymph nodes of athymic nude mice (BALB/c nu/nu). The specificity was assessed immunohistochemically on frozen sections of lymph nodes and epidermal sheets from both nude and normal mice. M1-8 reacted with paracortical IDC, veiled cells of the marginal sinus, and epidermal Langerhans cells in both normal and nude mice. In simultaneous staining by M1-8 and nonspecific esterase or anti-Ia or anti-Thy-1,2 antibody, the same epidermal dendritic cells were positive for all these antigens except Thy-1,2. Immunoelectron microscopy of the lymph node suspension using gold colloid particles revealed the attachment of gold particles to the cell membrane of IDC. Analysis by flow cytometry of the lymph node cell suspension showed 14 or 6% of M1-8-positive cells in nude or normal mouse, respectively. Immunohistochemical analysis showed that M1-8 also reacted with dendritic cells in the thymus and spleen and had a different distribution from F4/80. M1-8 also reacted with monocytes in bone marrow and peripheral blood, alveolar macrophages, and thioglycollate-stimulated peritoneal exudate macrophages. The antibody belongs to the immunoglobulin M class, reacts immunochemically with a glycoprotein in the cell membrane, and has a molecular mass of approximately 15 kDa.

Abstract
The effects of chronic intake of dietary alcohol on myocardial peroxidation (measured as formation of diene conjugates), reduced glutathione content, and morphology and the protective actions of different antioxidant compounds (vitamin E and (+)-cyanidanol-3) were studied in rats. Alcohol, comprising more than 30% of the dietary calorie content, was administered to rats for six weeks. Compared with the controls, the left ventricle of the alcoholic animals had an increased diene conjugate content (5.4(0.5) vs 4.3(0.6) optical density X g wet weight-1) and a slightly, but not significantly, decreased glutathione content (1.62(0.05) vs 1.66(0.07) mumol X g wet weight-1). Simultaneous administration of antioxidants (vitamin E or (+)-cyanidanol-3) prevented the pathological changes in diene conjugates and significantly increased the glutathione content compared with the alcoholic rats. Electron microscopy showed remarkably few ultrastructural abnormalities in the myocardium of alcoholic animals fixed by vascular perfusion. The data are consistent with the hypothesis that reactive oxygen radicals are involved in the ethanol induced biochemical changes and that the antioxidants could prevent the increased formation of peroxides in the myocardium.

Abstract
Models have been devised and characterized in the laboratory rat for studying the neuropathology of subarachnoid hemorrhage. Several ways of injecting blood via different routes have been tried; cortical subarachnoid administration is the most reproducible suitable model. The location of injected blood was detected in histological sections. In this rat model for subarachnoid hemorrhage, the arterial blood pressure and the intracranial pressure did not elevate significantly, and the influence of major ischemic components in the development of brain edema could also be ruled out. Measurements performed on the water, electrolyte, and albumin contents of brain tissue have clearly indicated that the brain edema developing in the acute stage of rat experimental subarachnoid hemorrhage could be classified as having a primarily vasogenic component as well. These findings may have implications in the treatment of subarachnoid hemorrhage.

Abstract
Detailed histological investigation of the brains of 45 neonates, infants and children who had died of various congenital heart defects revealed that the damage to the white matter occurred mostly below 3 months of age, while that to the grey matter occurred above this age. The lesions (glial fatty metamorphosis, telencephalic leucoencephalopathy, focal white matter necrosis, focal nerve cell pyknosis and symmetrical cortical necrosis) were often combined with each other. The necroses were generally not a consequence of microembolization. Various cerebral complications occurred in most of the patients who had undergone cardiac surgery. However, the various cerebral lesions each had several causes and in general the accumulation of predisposing damaging noxae resulted in more serious changes.

Abstract
Human serum albumin-like immunoreactivity was detected by the peroxidase-antiperoxidase method in histological sections of the hippocampus from epileptic and control brains obtained on routine autopsies. In the hippocampi of epileptic patients immunoreactive astrocytes were found, the number of which was increasing with the severity of the manifest convulsions. The highest numbers of immunoreactive astrocytes were observed in those patients who died in status epilepticus. Hippocampi from control patients with no neurologic disorders in life were devoid of immunoreactive astrocytes. The results are discussed in terms of the breakdown of the blood-brain barrier during epileptic seizures.

Abstract
Macroscopic, lights-and electron microscopic examination of 14 xenograft valve prostheses was carried out over a follow-up period of 1-49 months. 8 out of the 14 were acidic formaldehyde pretreated porcine aortic valves, 4 glutaraldehyde pretreated ones (Carpentier-Edwards) and 2 of them were glutaraldehyde calf's pericardium valves (Ionescu-Shiley). Formaldehyde pretreated grafts had to be surgically removed for valve failure. Glutaraldehyde grafts were obtained at autopsy. Until death, their function was excellent. The main pathological finding in both type of grafts was disintegration of collagen, which in glutaraldehyde grafts appeared to be of milder degree. In formaldehyde pretreated grafts cellular reaction indicating chronic rejection has also been observed. It is concluded that formaldehyde pretreated xenografts are not suitable for clinical use. On the other hand glutaraldehyde pretreated ones inspite of structural alterations may be functioning for years.
