Abstract
Roughness down to atomic and close-to-atomic scale is receiving an increasing attention in recent studies of manufacturing development, which can be realized by high-precision polishing processes. This review presents polishing approaches at atomic and close-to-atomic scale on planar and curved surfaces, including chemical mechanical polishing, plasma-assisted polishing, catalyst-referred etching, bonnet polishing, elastic emission machining, ion beam figuring, magnetorheological finishing, and fluid jet polishing. These polishing approaches are discussed in detail in terms of removal mechanisms, polishing systems, and industrial applications. The authors also offer perspectives for future studies to address existing and potential challenges and promote technological progress.

Abstract
Non alcoholic steatohepatitis (NASH) is the inflammatory reaction of the liver to excessive accumulation of lipids in the hepatocytes. NASH can progress to cirrhosis and hepatocellular carcinoma (HCC). Fatty liver is the hepatic manifestation of metabolic syndrome. A subclinical inflammatory state is present in patients with metabolic alterations like insulin resistance, type-2 diabetes, obesity, hyperlipidemia, and hypertension. Platelets participate in immune cells recruitment and cytokines-induced liver damage. It is hypothesized that lipid toxicity cause accumulation of platelets in the liver, platelet adhesion and activation, which primes the immunoinflammatory reaction and activation of stellate cells. Recent data suggest that antiplatelet drugs may interrupt this cascade and prevent/improve NASH. They may also improve some metabolic alterations. The pathophysiology of inflammatory liver disease and the implication of platelets are discussed in details.

Abstract
BACKGROUND Health concerns associated with the exposure to legacy perfluoro-alkyl substances (PFAS) led to the development of new-generation PFAS, such as C6O4. Here we investigated the possible effects of C6O4 on the platelet's activation profile, by incubating human platelets from healthy donors with C6O4 at different concentrations and evaluating the effects on activation, production and phenotype of platelets micro-particles (MPV) and aggregation under-flow. Based on the eventual platelet pro-aggregation profile detected, the preventive effect of acetylsalicylic acid (ASA) was also explored. METHODS Adhesion-induced platelet aggregation of platelet rich plasma (PRP) under flow was evaluated on collagen-coated microchip at a shear stress of 10 Dyne. The turbidimetric method was used to investigate platelet aggregation. Finally, the in vitro generation of pro-coagulant MPV in PRP was evaluated by flow cytometry, as characterized by CD41 and annexin V positive events, under resting conditions and after stimulation with agonists at low shear stress. RESULTS The generation of platelet aggregates under flow was significantly increased by the pretreatment of PRP with 100-200 ng/mL C6O4, compared to both the control condition and the experiment performed in presence of ASA. Arachidonic acid (AA), ADP and collagen induced an higher maximal aggregation, at turbidimetric evaluation, when PRP was pretreated with 100-500 ng/mL C6O4. In addition, PRP stimulated with AA also showed a steeper slope of the aggregation curve. The aggregation induced by the tested agonists was almost abolished by ASA. Finally, pretreatment with C6O4 increased the number of MPV in resting conditions and in presence of ADP and TRAP. ASA tended to reduce MPV generation. CONCLUSIONS Exposure to C6O4 associates with an increased platelet response to agonists, translating into a possible increased risk of cardiovascular events. Pending a further clarification on the toxicokinetics of this compound, our results claim the possible prophylactic use of ASA.

Abstract
BACKGROUND Ion channels are transmembrane proteins that play important roles in cell function regulation modulating ionic cell permeability. In megakaryocytes and platelets, regulated ion flows have been demonstrated to modulate platelet production and function. However, a relatively limited characterization of ion channel expression and function is available in the human megakaryocyte-platelet lineage. OBJECTIVE We analyzed the expression and function of the large-conductance calcium and voltage-activated potassium channel Kca 1.1 (also known as Maxi-K, BK, slo1) in human megakaryocytes and platelets. METHODS To investigate the functionality of Kca 1.1, we exploited different agonists (BMS-191011, NS1619, NS11021, epoxyeicosatrienoic acid isoforms) and inhibitors (iberiotoxin, penitrem A) of the channel. RESULTS In megakaryocytes, Kca 1.1 agonists determined a decreased proplatelet formation and altered interaction with the extracellular matrix. Analysis of the actin cytoskeleton demonstrated a significant decrease in megakaryocyte spreading and adhesion to collagen. In platelets, the opening of the channel Kca 1.1 led to a reduced sensitivity to agonists with blunted aggregation in response to ADP, with an inhibitory capacity additive to that of aspirin. The Kca 1.1 agonists, but not the inhibitors, determined a reduction of platelet adhesion and aggregation onto immobilized collagen underflow to an extent similar to that of aspirin and ticagrelor. The opening of the Kca 1.1 resulted in cell hyperpolarization impairing free intracellular calcium in ADP-stimulated platelets and megakaryocytes. CONCLUSIONS The present study reveals new mechanisms in platelet formation and activation, suggesting that targeting Kca 1.1 channels might be of potential pharmacological interest in hemostasis and thrombosis.

Abstract
The pectoralis major flap (PMF) is one of the most used pedicled flaps for reconstructive surgery in head and neck. Basing on previous studies observing that a vascular accident or pedicle ligation not always resulted in necrosis of free flaps, sometimes after a short critical period, we describe the possibility to perform the division of the PMF pedicle. The autonomization of PMF is based on the hypothesis that the flap, after a critical period, develops a neoangiogenesis at the free portion in the recipient site. It represents a possible choice in selected patients with relapse or second tumour of the oral floor and/or mobile tongue, who have been already treated with PMF reconstruction. We provide a step-by-step description of the autonomization and use of the modified PMF. Moreover, we reported advantages and pitfalls. The modified PMF represents a safe reconstructive choice for patients advised against a free flap or a second pedicled flap, with good surgical outcomes.

Abstract
Polyfluoro- and perfluoro-alkyl substances (PFAS) are organic chemicals extensively used worldwide for industry and consumer products. Due to their chemical stability, PFAS represent a major cause of environmental pollution. PFAS accumulate in animal and human blood and tissues exerting their toxicity. We performed a review of the epidemiological studies exploring the relationship between exposure to PFAS and thromboembolic cardiovascular disease. An increase in cardiovascular disease or death related to PFAS exposure has been reported from cross-sectional and longitudinal observational studies with evidence concerning the relation with early vascular lesions and atherosclerosis. Several studies indicate an alteration in lipid and glucose metabolism disorders and increased blood pressure as a possible link with cardiovascular thromboembolic events. We also examined the recent evidence indicating that legacy and new PFAS can be incorporated in platelet cell membranes giving a solid rationale to the observed increase risk of cardiovascular events in the populations exposed to PFAS by directly promoting thrombus formation. Exposure to PFAS has been related to altered plasma membrane fluidity and associated with altered calcium signal and increased platelet response to agonists, both in vitro and ex vivo in subjects exposed to PFAS. All the functional responses are increased in platelets by incorporation of PFAS: adhesion, aggregation, microvesicles release and experimental thrombus formation. These findings offer mechanistic support the hypothesis that platelet-centred mechanisms may be implicated in the increase in cardiovascular events observed in populations chronically exposed to PFAS.

Abstract
AIM OF THE STUDY AND PATIENTS Direct oral anticoagulants (DOA) tend to replace antivitamins K (VKA). The incidence of major and minor hemorrhages is higher in women, a difference potentially linked to genital hemorrhages. The objective is to assess the practices and perception of general practitioners of the use of oral anticoagulant therapy in women of childbearing age. MATERIALS AND METHODS Descriptive, observational, transversal and monocentric study. An 11-items questionnaire was sent to 900 randomized general practitioners, assessing the type of patient, the type of anticoagulant prescribed, the management of genital bleeding, and the assessment of the quality of life of anticoagulated patients. RESULTS DOA were the most prescribed anticoagulants. Genital hemorrhage was the second leading cause of minor hemorrhage. Most doctors (60.6%) believed they were due to VKAs. 25% reported an alteration in the quality of life of patients following these genital hemorrhages and 47.5% addressed this subject in consultation. CONCLUSION Our study suggests that, according to the general practitioners interviewed, genital hemorrhage is more frequent on VKA than on DOA in women of reproductive age, which is contradictory with the data in the literature. The probably taboo subject is rarely mentioned in consultation and is responsible for a deterioration in the quality of life in these young patients. No recommendation exists on the management of this type of genital hemorrhage in these women. An algorithm is proposed for their management.

Abstract
Abstract
In 1996, U.S. Food and Drug Administration regulations mandated the fortification of enriched cereal-grain products with folic acid, thereby emphasizing the need for validated methods for total folates in foods, particularly cereal products. The AOAC Official Methods (944.12, 960.46) currently used for the analysis of folate in foods for compliance purposes are microbiological methods. When the fortification regulations were finalized, no Official AOAC or Approved AACC methods for folate in cereal-grain products were in place. The AOAC Official Method (992.05) for folic acid in infant formula does not incorporate important improvements in the extraction procedure and was not considered suitable for the analysis of folates in foods in general. Amicrobiological assay protocol using a trienzyme extraction procedure was prepared and submitted for comments to 40 laboratories with recognized experience in folate analysis. On the basis of comments, the method was revised to have the conjugase (gamma-glutamyl-carboxy-peptidase) treatment follow a protease treatment, to include the use of cryoprotected inoculum, and to include the spectroscopic standardization of the standard and optional use of microtiter plates. Thirteen laboratories participated in a collaborative study of 10 required and 10 optional cereal-grain products, including flour, bread, cookies, baking mixes, and ready-to-eat breakfast cereals. The majority of the participating laboratories performed the assay by the standard test tube method; others used the microtiter plate modification for endpoint quantitation with equal success. For the required products, the relative standard deviation between laboratories (RSDR) ranged from 7.4 to 21.6% for 8 fortified (or enriched) products compared with expected (Horwitz equation-based) values of 11–20%. RSDR values were higher (22.7–52.9%) for 2 unfortified cereal-grain products. For the optional products, the RSDR ranged from 1.8 to 11.2% for 8 fortified products. RSDR values were higher (27.9–28.7%) for 2 unfortified cereal-grain products. Based on the results of the collaborative study, the microbiological assay with trienzyme extraction is recommended for adoption as Official First Action.

Abstract
Platelet-derived large extracellular vesicles (often referred to as microparticles in the field of cardiovascular disease) have been identified as effector in the atherothrombotic process, therefore representing a target of pharmacological intervention of potential interest. Despite that, limited evidence is so far available concerning the effects of antiplatelet agents on the release of platelet-derived extracellular vesicles. In the present narrative review, the mechanisms leading to vesiculation in platelets and the pathophysiological processes implicated will be discussed. This will be followed by a summary of the present evidence concerning the effects of antiplatelet agents under experimental conditions and in clinical settings.

Abstract
The article discusses a model for information value assessment based on the concepts of information capacity, information utility, and information management costs. Notwithstanding that both state-of-the-art researchers and practitioners consider information as a fundamental asset, there is actually no consensus on what are the determinants of information value, particularly with regard to the increasing number of data available through digitalized processes and services. The model is applied to a case study comparing two information management projects for the improvement of core business processes of a global manufacturing company based in Italy.

Abstract
Our preliminary evaluation of a new monoclonal antibody-based assay for tissue polypeptide antigen (TPA) has shown it to be clinically equivalent to the polyclonal antibody-based assay for TPA. The new assay (TPA-M) employs three monoclonal antibodies to epitopes on cytokeratins 8, 18 and 19. This multicenter, multinational study included 266 patients with newly diagnosed carcinomas of the lung, breast, large bowel and urinary bladder. TPA values from the two assays were compared with three other cytokeratin markers (TPS, CYFRA 21–1 and TPACyk) and with the established reference markers for these malignancies (CEA and NSE for lung, CA 15–3 for breast, CEA and CA 19–9 for colorectal tumors). Analysis of receiver operating characteristic (ROC) curves in lung, colorectal and bladder cancer showed similar sensitivities for the two assays, ranging from 50% to 80% with a specificity of 95%. In breast cancer all the markers studied showed poor sensitivity. However, TPA determination by either method could discriminate advanced stage (stages III and IV) from early stage disease (stages 0 to II). TPA showed similar discriminating ability in bladder cancer. On the basis of the results obtained in our patient series, it seems that of the cytokeratin markers studied, TPA and TPA-M are the most sensitive and offer a wide range of clinical applications.

Abstract
Serum levels of carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC) and immunosuppressive acidic protein (IAP) were measured in 37patients with lung cancers, in 24 with non-cancer pulmonary diseases and in 24 normal controls. We evaluated the sensitivity, specificity and accuracy of these three markers alone and combined. The highest specificity was observed for SCC (83.3%) and the highest sensitivity for IAP (94.6%). The best accuracy was obtained with the combined determination of CEA and SCC. In cancer and non-cancer pulmonary diseases the best correlation was observed between CEA and SCC (r=0.30 in cancer and r=0.45 in non-cancer pulmonary diseases). Although the IAP test is not specific in the detection of lung cancer, its use may be helpful in monitoring the acute phase reactions that occur very frequently in this malignancy.

Abstract
Serum levels of the immunosuppressive acidic protein (IAP) and CA-125 were measured in 45 patients with ovarian tumors (30 malignant and 15 benign) before surgery. Concentrations of both markers were slightly increased in benign forms but still within the upper limit for controls. The sensitivity of IAP in detecting ovarian cancer was higher than CA-125 (83.4% versus 76.7%). Five false negatives were observed in IAP assay and seven for CA-125. Parallel determination of both markers, however, improved the diagnostic accuracy up to 90.0% of the total malignant cases. Combined measurements of circulating IAP and CA-125 are therefore recommended in the detection of ovarian cancers.

Abstract
Recently, a new immunometric assay (Cyfra 21–1) was developed to measure serum concentrations of a soluble fragment of cytokeratin subunit 19. With this method, supplied by Boehringer Mannheim (EIA Test Cyfra 21–1), an Italian multicenter trial was performed in patients with lung cancer. Cyfra 21–1 serum levels were determined in 568 normal subjects (blood donors), 607 patients with non-malignant diseases (491 respiratory diseases) and 730 patients with malignancies. In the latter group 584 had lung cancer. All these 584 patients had pathologically confirmed disease; 314 were epidermoid tumors, 166 adenocarcinomas, 88 small cell cancers and 16 large cell cancers. In the 568 healthy blood donors the mean Cyfra 21–1 value was 0.91 ng/ml (SD 0.47 ng/ml; range 0.05–2.90 ng/ml). A threshold of 1.9 ng/ml was chosen as the upper limit of normality. High levels of Cyfra21–1 were observed in patients with chronic hepatitis (positivity rate: 17/51–33.3%) and with pancreatitis (positivity rate 5/16 - 31.3%). In 114 out of 491 (23.2%) patients with respiratory diseases Cyfra 21–1 showed values greater than 1.9 ng/ml. The overall sensitivity (all stages) of Cyfra 21–1 in lung cancer was 65.6% (383/584). When the histology was considered the highest positivity rates were found in patients with squamous cell tumors (226/314; 72%) followed by adenocarcinomas (105/166; 63%). In patients with SCLC the global sensitivity was 52.3% (46/88). Higher sensitivity of Cyfra 21–1 was observed from stage I to stage IV (53.9% vs 85.7%; Chisquare: p < 0.01). When comparing patients in whom curative resections were possible (up to stage IIIa) with patients suffering from inoperable tumors, a significant difference in Cyfra 21–1 positivies was found (59% vs 81.5%; Chi square p < 0.01).

Abstract
Newly isolated strains of the ciliate Paramecium calkinsi and their cytoplasmic bacterial endosymbionts were characterized by a multidisciplinary approach, including live observation, ultrastructural investigation, and molecular analysis. Despite morphological resemblance, the characterized P. calkinsi strains showed a significant molecular divergence compared to conspecifics, possibly hinting for a cryptic speciation. The endosymbionts were clearly found to be affiliated to the species "Candidatus Trichorickettsia mobilis" (Rickettsiales, Rickettsiaceae), currently encompassing only bacteria retrieved in an obligate intracellular association with other ciliates. However, a relatively high degree of intraspecific divergence was observed as well, thus it was possible to split "Candidatus Trichorickettsia" into three subspecies, one of which represented so far only by the newly characterized endosymbionts of P. calkinsi. Other features distinguished the members of each different subspecies. In particular, the endosymbionts of P. calkinsi resided in the cytoplasm and possessed numerous peritrichous flagella, although no motility was evidenced, whereas their conspecifics in other hosts were either cytoplasmic and devoid of flagella, or macronuclear, displaying flagellar-driven motility. Moreover, contrarily to previously analyzed "Candidatus Trichorickettsia" hosts, infected P. calkinsi cells frequently became amicronucleate and demonstrated abnormal cell division, eventually leading to decline of the laboratory culture.

Abstract
Objectives. The aim was to investigate whether the signalling lymphocyte activation molecule (SLAM) signalling pathways contribute to LN and whether SLAM receptors could be valuable biomarkers of disease activity. Methods. Peripheral blood mononuclear cells from 30National Research Ethics Service SLE patients with biopsy-proven LN were analysed by flow cytometry. Clinical measures of disease activity were assessed. The expression of the SLAM family receptors on T-cell subpopulations [CD4, CD8 and double negative (DN) T cells] was measured and compared between lupus patients with active renal disease and those in remission. Results. The frequency of CD8 T cells expressing SLAMF3, SLAMF5 and SLAMF7 was significantly lower in LN patients who were in remission. In contrast, these subsets were similar in patients with active renal disease and in healthy individuals. Patients with active nephritis had an increased percentage of circulating monocytes, consistent with a potential role played by these cells in glomerular inflammation. Changes in the frequency of DN T cells positive for SLAMF2, SLAMF4 and SLAMF7 were observed in lupus patients irrespective of the disease activity. We detected alterations in the cellular expression of the SLAM family receptors, but these changes were less obvious and did not reveal any specific pattern. The percentage of DN T cells expressing SLAMF6 could predict the clinical response to B-cell depletion in patients with LN. Conclusion. Our study demonstrates altered expression of the SLAM family receptors in SLE T lymphocytes. This is consistent with the importance of the SLAM-associated pathways in lupus pathogenesis.

Abstract
PURPOSE To evaluate the safety and efficacy of pelvic embolization using ethylene vinyl alcohol copolymer (Onyx®) for pelvic congestion syndrome. MATERIAL AND METHODS Between March 2012 to September 2016, 17 women (mean age, 44.7± 12.2 (SD) years; range: 34-71years) presenting with pelvic congestion syndrome were evaluated for transvenous embolization with Onyx®. Pelvic congestion syndrome was initially diagnosed by clinical examination and the results of transvaginal Doppler ultrasound and further confirmed by pelvic venography. Primary and secondary clinical efficacy was defined respectively by the resolution of the symptoms after embolization and at the end of the follow-up, irrespective to the number of embolization procedures. RESULTS Technical efficacy of embolization was 100% with no significant complications during and after embolization. After a mean follow-up time of 24.2 months (range: 6-69months) a primary and secondary clinical efficacy of 76.4% (13/17 women) and 94.1% (16/17 women) respectively were observed. Four women (23.5%) underwent a second embolization procedure with one woman requiring a third embolization procedure. These additional embolization procedures were associated with direct puncture of vulvar varices for sclerotherapy in two women. Five women (29%) had recurrent symptoms 21 months post-treatment (7-42months). CONCLUSION Pelvic embolization using ethylene vinyl alcohol copolymer (Onyx®) has a favorable clinical success for pelvic congestion syndrome.

Abstract
BACKGROUND AND PURPOSE Chemokines are involved in neuroinflammation and contribute to chronic pain processing. The new chemokine prokineticin 2 (PROK2) and its receptors (PKR1 and PKR2 ) have a role in inflammatory pain and immunomodulation. In the present study, we investigated the involvement of PROK2 and its receptors in neuropathic pain. EXPERIMENTAL APPROACH Effects of single, intrathecal, perineural and s.c. injections of the PKR antagonist PC1, or of 1 week s.c. treatment, on thermal hyperalgesia and tactile allodynia was evaluated in mice with chronic constriction of the sciatic nerve (CCI). Expression and localization of PROK2 and of its receptors at peripheral and central level was evaluated 10 days after CCI, following treatment for 1 week with saline or PC1. IL-1β and IL-10 levels, along with glia activation, were evaluated. KEY RESULTS Subcutaneous, intrathecal and perineural PC1 acutely abolished the CCI-induced hyperalgesia and allodynia. At 10 days after CCI, PROK2 and its receptor PKR2 were up-regulated in nociceptors, in Schwann cells and in activated astrocytes of the spinal cord. Therapeutic treatment with PC1 (s.c., 1 week) alleviated established thermal hyperalgesia and allodynia, reduced the injury-induced overexpression of PROK2, significantly blunted nerve injury-induced microgliosis and astrocyte activation in the spinal cord and restored the physiological levels of proinflammatory and anti-inflammatory cytokines in periphery and in spinal cord. CONCLUSION AND IMPLICATIONS The prokineticin system contributes to pain modulation via neuron-glia interaction. Sustained inhibition of the prokineticin system, at peripheral or central levels, blocked both pain symptoms and some events underlying disease progression.

Abstract
Background: In multiple sclerosis (MS), the location of focal lesions does not always correlate with clinical symptoms, suggesting disconnection as a major pathophysiological mechanism. Resting-state (RS) functional magnetic resonance imaging (fMRI) is believed to reflect brain functional connectivity (FC) within specific neuronal networks. Objective: RS-fMRI was used to investigate changes in FC within two critical networks for the understanding of MS disabilities, namely, the sensory-motor network (SMN) and the default-mode network (DMN), respectively, implicated in sensory-motor and cognitive functions. Methods: Thirty-four relapsing–remitting (RR), 14 secondary progressive (SP) MS patients and 25 healthy controls underwent MRI at 3T, including conventional images, T1-weighted volumes, and RS-fMRI sequences. Independent component analysis (ICA) was employed to extract maps of the relevant RS networks for every participant. Group analyses were performed to assess changes in FC within the SMN and DMN in the two MS phenotypes. Results: Increased FC was found in both networks of MS patients. Interestingly, specific changes in either direction were observed also between RR and SP MS groups. Conclusions: FC changes seem to parallel patients’ clinical state and capability of compensating for the severity of clinical/cognitive disabilities.

Abstract
BACKGROUND Brain disconnection plays a major role in determining cognitive disabilities in multiple sclerosis (MS). We recently developed a novel diffusion-weighted magnetic resonance imaging (DW-MRI) tractography approach, namely anatomical connectivitity mapping (ACM), that quantifies structural brain connectivity. OBJECTIVE Use of ACM to assess structural connectivity modifications in MS brains and ascertain their relationship with the patients' Paced-Auditory-Serial-Addition-Test (PASAT) scores. METHODS Relapsing-remitting MS (RRMS) patients (n = 25) and controls (n = 25) underwent MRI at 3T, including conventional images, T1-weighted volumes and DW-MRI. Volumetric scans were coregistered to fractional anisotropy (FA) images, to obtain parenchymal FA maps for both white and grey matter. We initiated probabilistic tractography from all parenchymal voxels, obtaining ACM maps by counting the number of streamlines passing through each voxel, then normalizing by the total number of streamlines initiated. The ACM maps were transformed into standard space, for statistical use. RESULTS RRMS patients had reduced grey matter volume and FA, consistent with previous literature. Also, we showed reduced ACM in the thalamus and in the head of the caudate nucleus, bilaterally. In our RRMS patients, ACM was associated with PASAT scores in the corpus callosum, right hippocampus and cerebellum. CONCLUSIONS ACM opens a new perspective, clarifying the contribution of anatomical brain disconnection to clinical disabilities in MS.

Abstract
BACKGROUND Inflammation triggers secondary neurodegeneration in multiple sclerosis (MS). OBJECTIVES It is unclear whether classical anti-inflammatory cytokines have the potential to interfere with synaptic transmission and neuronal survival in MS. METHODS Correlation analyses between cerebrospinal fluid (CSF) contents of anti-inflammatory cytokines and molecular, imaging, clinical, and neurophysiological measures of neuronal alterations were performed. RESULTS Our data suggest that interleukin-13 (IL-13) plays a neuroprotective role in MS brains. We found, in fact, that the levels of IL-13 in the CSF of MS patients were correlated with the contents of amyloid-β(1-42). Correlations were also found between IL-13 and imaging indexes of axonal and neuronal integrity, such as the retinal nerve fibre layer thickness and the macular volume evaluated by optical coherence tomography. Furthermore, the levels of IL-13 were related to better performance in the low-contrast acuity test and Multiple Sclerosis Functional Composite scoring. Finally, by means of transcranial magnetic stimulation, we have shown that GABAA-mediated cortical inhibition was more pronounced in patients with high IL-13 levels in the CSF, as expected for a neuroprotective, anti-excitotoxic effect. CONCLUSIONS The present correlation study provides some evidence for the involvement of IL-13 in the modulation of neuronal integrity and synaptic function in patients with MS.

Abstract
Terminally ill cancer patients are considered at high risk for pressure ulcers because of their clinical condition. However, in Italy, data about pressure ulcers and their prevalence are insufficient. This paper reports a study on pressure ulcers incidence and prevalence in a population of oncology patients cared for in an Italian palliative care service. A retrospective analysis of 414 clinical records of patients admitted over 6 months showed a prevalence of pressure ulcers of 22.9% and an incidence of 6.7%. Karnofsky Performance Scale Index scores, age and length of the stay were significantly related to the pressure sore development. These results support the need to focus attention on pressure ulcers prevention and treatment in terminally ill cancer patients, and to further define specific guidelines aimed at warranting patients' comfort and quality of life.

Abstract
The neurotransmitter acetylcholine (Ach) controls both excitatory and inhibitory synaptic transmission in the striatum. Here, we investigated the involvement of the endocannabinoid system in Ach-mediated inhibition of striatal GABA transmission, and the potential role of transient receptor potential vanilloid 1 (TRPV1) channels in the control of Ach-endocannabinoid coupling. We found that inhibition of Ach degradation and direct pharmacological stimulation of muscarinic M1 receptors reduced striatal inhibitory postsynaptic currents (IPSCs) through the stimulation of 2-arachidonoylglicerol (2AG) synthesis and the activation of cannabinoid CB1 receptors. The effects of M1 receptor activation on IPSCs were occlusive with those of metabotropic glutamate receptor 5 stimulation, and were prevented in the presence of capsaicin, agonist of TRPV1 channels. Elevation of anandamide (AEA) tone with URB597, a blocker of fatty acid amide hydrolase, mimicked the effects of capsaicin, indicating that endogenous AEA acts as an endovanilloid substance in the control of M1-dependent 2AG-mediated synaptic effects in the striatum. Accordingly, both capsaicin and URB597 effects were absent in mice lacking TRPV1 channels. Pharmacological interventions targeting AEA metabolism and TRPV1 channels might be considered alternative therapeutic routes in disorders of striatal cholinergic or endocannabinoid neurotransmission.

Abstract
UNLABELLED Cell proliferation control plays a key role in tumor development. The basic Fibroblast Growth Factor (bFGF), as well as other growth factors, is involved in several pathologies characterized by dysregulation of cell proliferation. In the present work the effects of PD166866, a very potent and selective tyrosine kinase inhibitor were evaluated. Cultured murine fibroblasts (the cell line 3T6) were used to assess the FGFR-1 inhibition mediated by PD166866. Evaluation of cell viability and molecular biology techniques were adopted. PD166866 controls negatively the bFGF/FGFR-1 system thus promoting a significant reduction of cell proliferation and loss of viability in 3T6 cells. The drug possibly controls proliferation via induction of apoptosis as evidenced by a relevant chromatin degradation. CONCLUSION This study demonstrated that PD166866 might be used in the control of fibrotic proliferative diseases, as well as in other tumor pathologies.
