Abstract
BACKGROUND Pulmonary sarcoidosis is a systemic disease that can confound established follow-up tools. Pulmonary function tests (PFTs) are recommended in initial and follow-up patient evaluations yet are imperfect predictors of disease progression. The cardiopulmonary exercise test (CPET) is another potentially useful monitoring tool, although previous studies report conflicting findings regarding which variables are altered by the disease. Nuclear imaging tests are also employed to assess inflammatory activity and may be predictive of functional deterioration. AIM We asked whether PFTs or CPET are more diagnostic of disease stage, which subsets of functional variables are impacted by the disease, and how these relate to nuclear imaging signs of active inflammation. STUDY DESIGN AND METHODS We collected retrospective data (spirometry, CPET, Gallium-67 scintigraphy, 18F-FDG PET/CT) from 48 patients and 10 controls. Disease severity was assessed following Scadding classification. First, we correlated individual PFTs and CPET parameters to Scadding stage and nuclear imaging data. Next, we performed Principal Component Analysis (PCA) on PFTs and CPET parameters, separated into respiratory, cardiovascular and metabolic subsets. Finally, we constructed multiple regression models to determine which variable subsets were the best predictors of Scadding stage and disease activity. RESULTS The majority of PFTs and CPET single parameters were significantly correlated with patient stage, while only few correlated with disease activity. Nevertheless, multiple regression models were able to significantly relate PFTs and CPET to both disease stage and activity. Additionally, these analyses highlighted CPET cardiovascular parameters as the best overall predictors of disease stage and activity. CONCLUSIONS Our results display how CPET and spirometry data complement each other for sarcoidosis disease staging, and how these tests are able to detect disease activity. Our findings suggest that CPET, a repeatable and non-invasive functional test, should be more routinely performed and taken into account in sarcoidosis patient follow-up.

Abstract
PURPOSE Sternal osteomyelitis is a major complication of cardiac operations performed through median sternotomy. The surgical treatment, which involves the debridement and removal of whole infected and necrotic tissue is the standard of care, although it is sometimes unachievable. This may occur, for instance, when the infectious-inflammatory process invades the anterior mediastinum and tenaciously incorporates one or more of vital anatomical structures. METHODS AND RESULTS An inoperable case of postoperative sternal osteomyelitis that involved the right ventricle and the right coronary artery, and that was successfully treated using a nonsurgical multidisciplinary approach, is reported here. CONCLUSION For highly selected patients with sternal osteomyelitis for whom surgery is a too risky option, an approach including the contribution of various specialists might be a viable way out.

Abstract
Visual hallucinations are prevalent, potentially disabling symptoms of Parkinson's Disease. Multiple impairments in bottom-up sensory processing and top-down perceptual modulation are implicated in the pathophysiology of these phenomena. In healthy individuals, visual illusions are elicited by illusory figures through parametric manipulations of geometrical configurations, contrast, color, or spatial relationships between stimuli. These illusory percepts provide insight on the physiologic processes subserving conscious and unconscious perception. In this exploratory, cross-sectional, controlled study, perceptual performance on illusory figures was assessed on 11 PD patients with hallucinations, 10 non-hallucinating PD patients, and 10 age-matched healthy individuals. In order to characterize potential neural substrates of perceptual performances, patients' brain metabolic patterns on FDG PET were also analyzed. Illusions relying on attentional modulation and global perception were attenuated in PD patients without hallucinations. This pattern was no longer recognizable in hallucinating patients. Conversely, illusory effects normally counteracted by figure to background segregation and overlapping figures recognition were enhanced in PD patients with hallucinations. FDG PET findings further suggest that perceptual differences between PD patients might be linked to abnormal top-down perceptual modulation.

Abstract
Our aim was to assess the detection rate (DR) of positron emission computed tomography (PET/CT) with anti-1-amino-3-[18F]-flurocyclobutane-1-carboxylic acid (18F-FACBC) in patients with biochemical recurrence (BCR) from prostate cancer (PC). As a secondary endpoint, we evaluated 18F-FACBC PET/CT’s impact on patients management. Clinical records of 81 patients submitted to 18F-FACBC PET/CT due to PC BCR in two Italian Nuclear Medicine Units were retrospectively assessed. DR was gauged in the whole cohort and stratifying patients by discrete intervals of PSA levels. PET/CT’s impact on clinical management was scored as (1) major if it entailed an intermodality change (e.g., from systemic to loco-regional therapy); (2) minor if it led to an intramodality change (e.g., modified radiotherapy field). PET/CT’s DR resulted in 76.9% in the whole cohort, with a positive predictive value of 96.7%. Stratified by PSA quartile intervals, PET/CT’s DR was 66.7%, 71.4%, 78.9% and 90% for PSA 0.2–0.57 ng/mL, 0.58–0.99 ng/mL, 1–1.5 ng/mL and >1.5 ng/mL without significant difference among groups (p = 0.81). The most common sites of relapse were prostate bed and pelvic lymph nodes (59.3%). PET/CT impacted on clinical management in 33/81 cases (40.7%), leading to a major change in 30 subjects (90.9%). 18F-FACBC PET/CT localized recurrence in patients with BCR, with meaningful DR also at low PSA levels and significantly impacted on clinical management.

Abstract
BACKGROUND Autoimmune limbic encephalitis (LE) is a neurological condition characterized by seizures and cognitive dysfunction. Fluorine-18 fluorodeoxyglucose (18F-FDG-PET) has recently proved to be an important diagnostic tool in this condition since it may highlight brain metabolism abnormalities in a very early stage of the disease. Two main 18F-FDG-PET patterns have been described: the mixed hypermetabolic/hypometabolic and the neurodegenerative one. Arterial spin labeling (ASL) is an MRI technique showing brain perfusion, rarely used in autoimmune neurological conditions. The aim of the present study was to study patients with LE with both techniques, in order to compare their results. METHODS Two patients with LE underwent to 18F-FDG-PET and ASL MRI scans using the pseudo-continuous arterial spin labeling (PCASL) technique. Areas of altered perfusion and metabolism were analyzed by visual inspection, and findings were compared between the two techniques. RESULTS In the first patient, a relapsing LGI-1 LE, right hippocampal hypermetabolism was detected by 18F-FDG-PET (mixed hypermetabolic/hypometabolic pattern), while ASL MRI showed right hippocampal increased perfusion. In the second patient, a seronegative LE, 18F-FDG-PET scan detected a left hemispheric hypoperfusion (neurodegenerative pattern) and ASL MRI yielded similar results. The two 18F-FDG-PET patterns of altered metabolism were similarly detected by ASL imaging. CONCLUSION ASL and 18F-FDG-PET findings are strongly concordant in LE. ASL imaging was able to detect the two main 18F-FDG-PET patterns previously described in patients with LE.

Abstract
Aim of this commentary is to report current knowledges on the main clinical and metabolic abnormalities which might be observed in children with longstanding and untreated subclinical hypothyroidism (SH) and to comment the most recent views about natural evolution of thyroid function in the cases with either idiopathic or Hashimoto’s thyroiditis-related SH. On the basis of these preliminary remarks, the essential guidelines for an appropriate and tailored management of SH children are also proposed.

Abstract
Drug-effect phenotypes in human lymphoblastoid cell lines recently allowed to identify CHL1 (cell adhesion molecule with homology to L1CAM), GAP43 (growth-associated protein 43) and ITGB3 (integrin beta 3) as new candidates for involvement in the antidepressant effect. CHL1 and ITGB3 code for adhesion molecules, while GAP43 codes for a neuron-specific cytosolic protein expressed in neuronal growth cones; all the three gene products are involved in synaptic plasticity. Sixteen polymorphisms in these genes were genotyped in two samples (n=369 and 90) with diagnosis of major depressive episode who were treated with antidepressants in a naturalistic setting. Phenotypes were response, remission and treatment-resistant depression. Logistic regression including appropriate covariates was performed. Genes associated with outcomes were investigated in the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) genome-wide study (n=1861) as both individual genes and through a pathway analysis (Reactome and String databases). Gene-based analysis suggested CHL1 rs4003413, GAP43 rs283393 and rs9860828, ITGB3 rs3809865 as the top candidates due to their replication across the largest original sample and the STAR*D cohort. GAP43 molecular pathway was associated with both response and remission in the STAR*D, with ELAVL4 representing the gene with the highest percentage of single nucleotide polymorphisms (SNPs) associated with outcomes. Other promising genes emerging from the pathway analysis were ITGB1 and NRP1. The present study was the first to analyze cell adhesion genes and their molecular pathways in antidepressant response. Genes and biomarkers involved in neuronal adhesion should be considered by further studies aimed to identify predictors of antidepressant response.

Abstract
BACKGROUND Antipsychotic medications (APM) are the first line pharmacological treatment for psychotic disorders and other behavioral disorders. Nevertheless, their use causes a number of side effects, including extrapyramidal symptoms (EPS). EPS decrease the efficacy of the antipsychotic treatments by causing poorer compliance to the treatment, stigma and a poorer quality of life for patients. Genetic studies hold the potential to unravel the molecular underpinnings of the EPS induced by APM but results are not conclusive and are far to be used in clinical practice despite decades of research. A more sophisticated selection of the list of genetic mutations explaining the genetic variance of EPS induced by APM could help in the definition of a personalized treatments for patients. Moreover, it would increase the quality of the current treatments with APM. METHODS We reviewed the literature searching for the genetic association studies focused on dystonia, parkinsonism, akathisia and tardive dyskinesia. Moreover, we reviewed the current biological knowledge of the APM induced side effects. Finally, we provide a reasoned list of candidate genes and their genetic variations, with the aim of identifying a list of candidates for APM induced EPS genetic investigations. RESULTS Variations located within PIK3CA (phosphoinositide-3- kinase, catalytic, alpha polypeptide), PLA2G4A (phospholipase A2, group IVA, cytosolic, calcium-dependent), PRKCA (protein kinase C, alpha), PRKACG (Phosphatidylinositol-4,5-bisphosphate 3-kinase 110 kDa catalytic subunit gamma), ERK-1 (extracellular signalregulated kinase 1 (MAPK3)), ERK-2 (extracellular signal-regulated kinase 2 (MAPK1)), GNAS (guanine nucleotide binding protein (G protein), alpha stimulating activity polypeptide 1), PLCB1 (phospholipase C, beta 1 (phosphoinositide-specific)) and ITPR1 (inositol 1,4,5-triphosphate receptor type 1) were found to be relevant for APM induced EPS. Some of the genes are classical candidates for this kind of research, others were never investigated. For each of these genes we provide a list of variations that balances the limitations of multitesting with the advantages of the tagging approach. CONCLUSIONS We undertook a review of the literature about the APM induced EPM to provide some rational genetic candidates to be tested in further genetic investigations.

Abstract
The aim of the present study is to evaluate the contribution of mitogen-activated protein kinase 1-3 MAPK3/MAPK1) in a model of acute lung inflammation in mice. Injection of carrageenan into the pleural cavity of mice elicited an acute inflammatory response characterized by: accumulation of fluid containing a large number of neutrophils (PMNs) in the pleural cavity, infiltration of PMNs in lung tissues and subsequent adhesion molecule expression (I-CAM and P-selectin), lipid peroxidation, and increased production of tumour necrosis factor-alpha, (TNF-alpha) and interleukin-1beta (IL-1beta). Furthermore, carrageenan induced lung apoptosis (Bax and Bcl-2 expression) as well as nitrotyrosine formation, NF-kB activation, and pJNK expression, as determined by immunohistochemical analysis of lung tissues and the degree of lung inflammation and tissue injury (histological score). Administration of PD98059, an inhibitor of MAPK3/MAPK1 (10 mg/kg) 1 h after carrageenan caused a reduction in all the parameters of inflammation measured. Thus, based on these findings we propose that inhibitors of the MAPK3/MAPK1 signaling pathways, such as PD98059, may be useful in the treatment of various inflammatory diseases.

Abstract
Granuloma is a focal, compact collection of inflammatory cells in which mononuclear phagocytes predominate. The authors report 9 cases of papillary-tubular gastric adenocarcinomas characterized by mature granulomas associated with recent microhemorrhages. Mature granulomas were composed of foamy, CD68-positive histiocytes with occasional giant cells. Hemosiderin-containing macrophages were present in the tumor stroma, suggesting phagocytosis of erythrocytes. Under electron microscopy, mature (nonepithelioid) granulomas and clusters containing 1 macrophage and 1-3 eosinophils were found. This study provides morphological examples of skewed type II macrophage infiltration in gastric adenocarcinomas that is involved in scavenging activity, particularly erythrophagocytosis, formation of mature (nonepithelioid granulomas), and heterotypic aggregation with eosinophils.

Abstract
In the present study, we used tumour necrosis factor-alpha receptor 1 knock-out mice (TNF-alphaR1KO) to evaluate an in vivo role of TNF-alphaR1 on the pathogenesis of inflammatory diseases. We used a murine model of carrageenan-induced acute inflammation (pleurisy), a preclinical model of airway inflammation. The data proved that TNF-alphaR1KO were resistant to carrageenan-induced acute inflammation compared with TNF-alpha wild-type mice. TNF-alphaR1KO showed a significant reduction in accumulation of pleural exudate and in the number of inflammatory cells, in lung infiltration of polymorphonuclear leucocytes and lipid peroxidation and showed a decreased production of nitrite/nitrate in pleural exudates. Furthermore, the intensity and degree of the adhesion molecule intercellular adhesion molecule-1 and P-selectin, Fas ligand (FasL), inducible nitric oxide sythase and nitrotyrosine determined by immunohistochemical analysis were reduced markedly in lung tissues from TNF-alphaR1KO at 4 h and 24 h after carrageenan injection. Moreover, TNF-alpha and interleukin-1beta concentrations were reduced in inflamed areas and in pleural exudates from TNF-alphaR1KO. To support the results generated using pleural inflammation, carrageenan-induced paw oedema models were also performed. In order to elucidate whether the observed anti-inflammatory effects were related to the inhibition of TNF-alpha, we also investigated the effect of etanercept, a TNF-alpha soluble receptor construct, on carrageenan-induced pleurisy. The treatment with etanercept (5 mg/kg subcutaneously 2 h before the carrageenan injection) reduces markedly both laboratory and histological signs of carrageenan-induced pleurisy. Our results showed that administration of etanercept resulted in the same outcome as that of deletion of the TNF-alphaR1 receptor, adding a new insight to TNF-alpha as an excellent target by therapeutic applications.

Abstract
A rare case of a 46-year-old woman with bilateral Krukenberg tumours is reported. Histologically, oedematous ovarian stroma was infiltrated by signet-ring cells arranged singly, in cords or in nests. Immunoreactivity for cytokeratin-7, carcinoembryonic antigen as well as histochemical positivity for mucins demonstrated the epithelial nature of the tumour. The gastric primary site was suggested by the cytoplasmic immunoreactivity for MUC-5AC and by ultrastructural evidence of gastric differentiation in signet-ring cells such as mucous granules with eccentric dense cores and intracellular microcysts, lined by sparse microvilli. Gastric biopsy, performed after pathological diagnosis, revealed a signet-ring cell carcinoma similar to that in the ovaries, confirming the gastric origin of the Krukenberg tumour. Because none of the individual immunohistochemical markers used for tissue identification is both site specific and site sensitive, electron microscopy in combination with immunohistochemistry is a valuable tool for the pathologist in the diagnosis of the tissue origin of a Krukenberg tumour.

Abstract
The aim of our study was to evaluate the therapeutic efficacy of combination therapy with etanercept and dexamethasone (DEX) in vivo in experimental murine model of spinal cord trauma, which was induced by the application of vascular clips (force of 24 g) to the dura via a four-level T5-T8 laminectomy. Spinal cord injury in mice resulted in severe trauma characterized by edema, neutrophil infiltration, and cytokine production followed by recruitment of other inflammatory cells, production of inflammation mediators, tissue damage, apoptosis and disease. Treatment of the mice with etanercept (1.25 mg/kg) and DEX (0.025 mg/kg) when administered as a combination therapy but not as a single treatment significantly reduced the degree of (1) spinal cord inflammation and tissue injury (histological score), (2) infiltration of neutrophils (MPO evaluation), (3) inducible nitric oxide synthase, nitrotyrosine, and cytokines expression (tumor necrosis factor-alpha and interleukin-1 beta), (4) and apoptosis (Terminal deoxynucleotidyltransferase-mediated UTP end labeling staining, Fas-ligand expression and Bax and Bcl-2 expression). In a separate set of experiments we have also clearly demonstrated that the combination therapy significantly ameliorated the recovery of limb function (evaluated by motor recovery score). Taken together, our results clearly demonstrate for the first time that strategies targeting multiple proinflammatory pathways may be more effective than a single effector molecule for the treatment of spinal cord trauma.

Abstract
BACKGROUND AND PURPOSE Etanercept is a tumour necrosis factor antagonist with anti-inflammatory effects. The aim of our study was to evaluate, for the first time, the therapeutic efficacy of in vivo inhibition of TNF-alpha in an experimental model of periodontitis. EXPERIMENTAL APPROACH Periodontitis was induced in adult male Sprague-Dawley rats by placing a nylon thread ligature around the lower 1st molars. Etanercept was administered at a dose of 5 mg kg-1, s.c., after placement of the ligature. KEY RESULTS Periodontitis in rats resulted in an inflammatory process characterized by oedema, neutrophil infiltration and cytokine production that was followed by the recruitment of other inflammatory cells, production of a range of inflammatory mediators, tissue damage, apoptosis and disease. Treatment of the rats with etanercept (5 mg kg-1, s.c., after placement of the ligature) significantly reduced the degree of (1) periodontitis inflammation and tissue injury (histological score), (2) infiltration of neutrophils (MPO evaluation), (3) iNOS (the expression of nitrotyrosine and cytokines (eg TNF-alpha)) and (4) apoptosis (Bax and Bcl-2 expression). CONCLUSIONS AND IMPLICATIONS Taken together, our results clearly demonstrate that treatment with etanercept reduces the development of inflammation and tissue injury, events associated with periodontitis.

Abstract
A case of hepatoid adenocarcinoma of the stomach is presented. The characteristic features of the tumor are summarized on the basis of the authors' experience and the literature. Ultrastructural examination revealed patchy condensations of chromatin throughout the nucleus suggestive of necrosis-like programmed cell death (PCD). These nuclear alterations were associated with the occurrence of vacuoles and lipofuscins, conferring an autophagic phenotype to this PCD. Thus, the case reported here provides an example of autophagic-related necrosis-like PCD. Alternative PCDs are reviewed and their morphologic distinction is discussed.

Abstract
BACKGROUND AND PURPOSE Glycogen synthase kinase-3 (GSK-3) is a ubiquitous serine-threonine protein kinase that participates in a multitude of cellular processes and has recently been implicated in the pathophysiology of a number of diseases. The aim of this study was to investigate the effects of GSK-3beta inhibition in a model of acute inflammation. Here, we have investigated the effects of TDZD-8, a potent and selective GSK-3beta inhibitor, in a mouse model of carrageenan-induced pleurisy. EXPERIMENTAL APPROACH Injection of carrageenan into the pleural cavity of mice elicited an acute inflammatory response characterized by: accumulation of fluid containing a large number of neutrophils (PMNs) in the pleural cavity, infiltration of PMNs in lung tissues and subsequent lipid peroxidation, and increased production of nitrite/nitrate (NOx), prostaglandin E2 (PGE2), tumour necrosis factor-alpha, (TNF-alpha) and interleukin-1beta (IL-1beta). Furthermore, carrageenan induced an upregulation of the adhesion molecules ICAM-1 and P-selectin, iNOS, COX-2 as well as nitrotyrosine as determined by immunohistochemical analysis of lung tissues. KEY RESULTS Administration of TDZD-8 (1, 3 or 10 mg kg(-1), i.p.), 30 min prior to injection of carrageenan, caused a dose-dependent reduction in all the parameters of inflammation measured. CONCLUSIONS AND IMPLICATIONS Thus, based on these findings we propose that inhibitors of the activity of GSK-3beta, such as TDZD-8, may be useful in the treatment of various inflammatory diseases.

Abstract
The removal of organic species from aqueous solution by activated carbons is investigated. The latter ones are prepared from olive husks and almond shells. A wide range of surface area values are obtained varying temperature and duration of both carbonization and activation steps. The adsorption isotherm of phenol, catechol and 2,6-dichlorophenol involving the activated carbons prepared are obtained at 25 degrees C. The corresponding behavior is quantitatively correlated using classical isotherm, whose parameters are estimated by fitting the equilibrium data. A two component isotherm (phenol/2,6-dichlorophenol) is determined in order to test activated carbon behavior during competitive adsorption.

We studied the effects of pre-treatment (15 days) with oral administration of Ginkgo biloba extract (Ph-Gb 37.5-150 mg/kg) on brain malonildialdehyde (MDA), brain edema, brain nitrite and nitrate and delayed neuronal death following transient cerebral ischemia in the Mongolian gerbil. Survival was not modified, however, pre-treatment with Ginkgo biloba significantly and in a dose-dependent way reduced post-ischemic brain MDA levels and post-ischemic brain edema. Delayed neuronal death in the CA1 of the hippocampus was attenuated by the highest dose of the extract. Increase of nitrite and nitrate was observed after cerebral ischemia in the hippocampus and it was dose-dependently reduced in animals pretreated with Ph-Gb, thus suggesting that neuroprotective effects of Ginkgo biloba may be due to an inhibitory action on nitric oxide formation.

Abstract
The presence of lactoferrin in astrocytomas, anaplastic astrocytomas and multiforme glioblastomas was determined by immunohistochemistry; the staining intensity and the percentage of neoplastic stained cells were graded and statistical analysis was performed by non-parametric methods. A moderate to strong diffuse immunoreactivity for lactoferrin was shown in glial elements of astrocytomas, while the positivity was progressively reduced in anaplastic astrocytomas and in multiforme glioblastomas, some of which were unstained; a highly significant difference was found between scores relative to astrocytomas and glioblastomas. We suggest that the lactoferrin may be produced by neoplastic astrocytes which permits a greater availability of iron for metabolic cellular processes. Alternatively, the cytoplasmic localization of lactoferrin in neoplastic astrocytes may be the consequence of defective or functionally impaired lactoferrin receptors at the cellular surface.

Abstract
We have investigated the quantity of argyrophilic nucleolar organizer region (AgNOR) proteins in vastus lateralis muscle samples from 13 patients with Duchenne muscular dystrophy (DMD) (6 months-12 years), 9 with Becker muscular dystrophy (BMD) (13 months-36 years), 9 with polymyositis (PM) (8-77 years) and 10 normal subjects (5 months-32 years). AgNORs were visualized on 4-microm-thick cryostat sections and quantified according to the guidelines of the Committee on AgNOR Quantitation; statistical analysis was performed on the mean AgNOR area (NORA) values. The mean NORA values encountered in DMD (4.327+/-0.791 microm2), BMD (3.534+/-0.312 microm2) and PM (3.785+/-0.424 microm2) samples were significantly (P<0.001) higher than those of normal muscle (1.682+/-0.288 microm2); a value of P<0.001 was also obtained when NORA values found in DMD were compared with those of BMD or PM. In addition, when NORA values were exclusively calculated in regenerating myofibers in DMD, BMD and PM, no differences were appreciable. On the other hand, in non-regenerating myofibers, the NORA values showed a significant increase in DMD versus BMD and PM (P<0.001) as well as in each disease group versus controls. Our study documents that muscle diseases, such as DMD, BMD and PM in which regeneration is a constant finding, have a high rDNA transcriptional activity. In particular, our findings suggest that (1) regenerating nuclei behave in the same way in dystrophinopathies or PM; (2) virtually all nuclei, including quiescent-looking ones, are activated to realize an increased intracellular protein synthesis for proliferative and/or functional purposes; and (3) the quantity of AgNOR does not seem related to age of patients at the time of biopsy.

Abstract
In the present study we tested the hypothesis that nitric oxide may play a role in the pathogenesis of multiple organ failure induced by peritoneal injection of zymosan in the rat. A severe inflammatory response characterized by peritoneal exudation, high plasma and peritoneal levels of nitrate/ nitrite (breakdown products of nitric oxide), prostaglandin E2 and leukocyte infiltration into peritoneal exudate was induced by zymosan administration. This inflammatory process started within 3 h of administration and onset occurred at 18 h, coinciding with damage of lung, small intestine and liver, as assessed by histological examination and by increase of myeloperoxidase activity, indicative of neutrophil infiltration. Furthermore, at 18 h after zymosan-induced peritonitis, expression of inducible nitric oxide synthase enzyme was found mainly in the macrophages of inflamed lungs. Subcutaneously administration of a nonisoform selective nitric oxide synthase inhibitor, NG-nitro-L-arginine methyl ester, reduced formation of peritoneal exudate fluid, blocked plasma and peritoneal nitrate/nitrite accumulation, and attenuated the elevated release of peritoneal prostaglandin E2. In addition, nitric oxide synthase inhibition was effective in preventing the development of organ failure since tissue injury and neutrophil infiltration, by myeloperoxidase evaluation, was reduced in lung, small intestine, and liver. In conclusion, major findings of our study are that nitric oxide exerts a proinflammatory role in the development of multiple organ failure and nitric oxide synthase inhibition is an effective antiinflammatory therapeutic tool, since inhibits not only nitric oxide but also prostaglandin production and cellular infiltration in inflamed organs.

Abstract
Restoration of blood flow after an ischaemic event generates the formation of oxygen radicals which could augment brain damage. The authors studied the effects of different doses (50, 100, 200 mg/kg/i.p.) of a new antioxidant, IRFI-016, [2(2,3-dihydro-5-acetoxy-4,6,7-trimethylbenzofuranyl) acetic acid] on brain damage in the Mongolian gerbil induced by 5 min of bilateral carotid occlusion (BCO) followed by reperfusion. Post-ischaemic brain malondialdehyde (MDA) levels and locomotor activity at different times and delayed neuronal death of hippocampal CA1 area on the fourth day after occlusion were evaluated. During reperfusion, after BCO, enhancement of brain MDA occurs (37.5%, 62.5% and 100% at 15, 30 and 60 min of reperfusion, respectively). Brain MDA postischaemic increases were reduced at 15 min of reperfusion to 15.4% and 44.4% by IRFI-016, 100 and 200 mg/kg, respectively. After 30 min of reperfusion brain MDA was reduced to 31.25% and 53.13% by IRFI-016 100 and 200 mg/kg, respectively. Hyperactivity and delayed neuronal death of CA1 were significantly reduced in postischaemic gerbils treated with the highest doses of IRFI-016. Results indicate that pretreatment with the antioxidant IRFI-016 improves in a dose-dependent manner brain damage induced by ischaemia and reperfusion in the gerbil.

Abstract
By immunocytochemistry, the presence of major iron-binding proteins (lactoferrin, transferrin and ferritin) was investigated in tubular adenomas (12 cases), villous adenomas (7 cases), carcinomas of the large bowel and rectum (39 cases) and lymph nodes involved in carcinomas (8 cases); 5 samples of colonic inflammatory pseudopolyps were also studied. Dysplastic areas of tubular and villous adenomas as well as adenocarcinomas and colloid carcinomas showed a variable cytoplasmic immunoreactivity for all antisera, although no staining was noted in some cases; tubular adenomas without dysplasia and colonic inflammatory pseudopolyps were always unstained. Metastatic elements present in lymph nodes maintained the immunohistochemical staining for iron-binding proteins. An autoctone production of lactoferrin, transferrin and ferritin by tumour cells may be hypothesized in relation to the increased requirement of iron for the turnover of rapidly dividing cells.

Abstract
The Authors have applied the AgNOR technique to a series of normal and pathological human tissues fixed in neutral buffered formalin and methacarnoy and embedded in glycol-methacrylate. The results show the compatibility of the AgNOR technique with this embedding medium as well as the possibility to obtain an adequate visualization of the specific silver precipitates (AgNORs) on a unique focal plane without appreciable nuclear overlap, making thus the valuation of the AgNORs less subjective.

Abstract
By endothelial markers such as FVIII, UEA-I, CD31 and QBEND/10, the Authors have investigated the immunohistochemical pattern of bone marrow megakaryocytes in myelodysplastic (8 cases) and myeloproliferative (35 cases) disorders as well as in control biopsies (8 cases). An evident cytoplasmic positivity with FVIII and UEA-I was encountered in all normal and pathological specimens, whereas the immunolocalization of CD31 was limited to megakaryocytes present in normal bone marrow biopsies or in cases of myelofibrosis. No immunostaining with QBEND/10 was observed in any case, although the most selective staining of endothelial cells of bone marrow vessels was noted with this antibody. The usefulness to utilize endothelial markers in order to identify atypical and immature forms of megakaryocytes as well as micromegakaryocytes, especially in myelofibrosis by the aid of CD31, was also discussed.

Abstract
Intracytoplasmic estradiol content was studied retrospectively using immunohistochemical procedures in tissue samples from subjects suffering from colorectal cancer. The results obtained reveal the presence of intracytoplasmic estradiol in cancer tissue. In precancerous lesions this presence is rarer and inconstant. Estradiol was not detected in the healthy tissue examined. These data suggest that such tumours may depend to some degree on endocrine factors.
