Abstract
Chronic kidney disease is a progressive condition that affects more than 10% of the general population worldwide. Hemodialysis is the most common therapeutic option for kidney failure, which develops in around one out of 1000 individuals in the general population. Hemodialysis needs a vascular access to connect to the extracorporeal machine. In the last few years percutaneous endovascular arterio-venous fistula technique has been increasingly employed with very promising results. Several advantages have been demonstrated in comparison to the standard surgical creation of an arteriovenous fistula. The percutaneous endovascular arterio-venous fistula technique requires multidisciplinary team work. In our practice, we have organized a multidisciplinary team that includes nephrologists, play a key role, interventional radiologists, vascular surgeons, anesthesiologists, and dialysis nurses. Procedural outcomes and feedback received from patients and family members are evaluated periodically in order to improve results. Nephrologists are involved in each step of the management of the percutaneous endovascular arterio-venous fistula: selection, mapping, creation, and follow up. Patient empowerment, education and involvement is required at each step. A dedicated training program, involving patients and the caregiver team is therefore needed. Additional research is required to confirm the benefit of the multidisciplinary team management in end-stage kidney disease patients.

Abstract
While global patterns of human genetic diversity are increasingly well characterized, the diversity of human languages remains less systematically described. Here, we outline the Grambank database. With over 400,000 data points and 2400 languages, Grambank is the largest comparative grammatical database available. The comprehensiveness of Grambank allows us to quantify the relative effects of genealogical inheritance and geographic proximity on the structural diversity of the world's languages, evaluate constraints on linguistic diversity, and identify the world's most unusual languages. An analysis of the consequences of language loss reveals that the reduction in diversity will be strikingly uneven across the major linguistic regions of the world. Without sustained efforts to document and revitalize endangered languages, our linguistic window into human history, cognition, and culture will be seriously fragmented.

Abstract
The purpose of thermal ablation is induction of tumor death by means of localized hyperthermia resulting in irreversible cellular damage. Ablative therapies are well-recognized treatment modalities for HCC lesions and are considered standard of care for HCC nodules < 3 cm in diameter in patients not suitable for surgery. Effective lesion treatment rely on complete target volume ablation. Technical limitations are represented by large (> 3 cm) or multicentric nodules as well as complex nodule location and poor lesion conspicuity. Artificial Intelligence (AI) is a general term referred to computational algorithms that can analyze data and perform complex tasks otherwise prerogative of Human Intelligence. AI has a variety of application in percutaneous ablation procedures such as Navigational software, Fusion Imaging, and robot-assisted ablation tools. Those instruments represent relative innovations in the field of Interventional Oncology and promising strategies to overcome actual limitations of ablative therapy in order to increase feasibility and technical results. This work aims to review the principal application of Artificial Intelligence in the percutaneous ablation of primary lesions of the liver with special focus on how AI can impact in the treatment of HCC especially on potential advantages on the drawbacks of the conventional technique.

Abstract
Hand-foot syndrome (HFS) is a common skin toxicity of traditional chemotherapies. Some studies showed that HFS has an association with progression-free survival (PFS) and the overall survival (OS). So far, there is not available any systematic literature reviews or meta-analysis aimed to assess the associations between HFS, PFS and OS. For this reason, this study aims to quantitatively summarize, critically review, and interpret the recent literature related to the associations between HFS and efficacy of chemotherapy in terms of PFS and OS. Queries shaped by PICOM framework, a systematic search of three electronic databases (PubMed, Scopus, and Science Direct) was carried out for the period between January 2010 and December 2017. Quantitative data pooling was based on the calculation of Hazard Ratio (HR) with 95% Confidence Interval (95% CI) for the OS and PFS associated to the presence of HFS, through the data of original publications. Five papers were included in this systematic review for the quantitative data pooling. Patients with HFS showed improved PFS (HR = 0.532 [0.431-0.656]; p = 0.000) and improved OS (HR = 0.522 [0.427-0.638]; p = 0.000). HFS causes a reduction of compliance with oncology treatments. Healthcare providers should use this result as a trigger to foster patients' coping and the one of their family caregivers, enhancing their adherence to cancer treatments.

Abstract
Abstract
Objective
The Neurobehavioral Symptom Inventory (NSI) is a self-report measure used to evaluate physical and mental health symptoms secondary to traumatic brain injury (TBI) in the Department of Veterans Affairs health care system. There has been little research examining the relationship between anxiety reported on the NSI and other anxiety screening measures. The purpose of the study was to compare single-item response on item 19 (i.e., feeling anxious or tense) of the NSI to symptoms as reported on the Beck Anxiety Inventory (BAI).
Method
Retrospective data collected from veteran patients (N = 321) of a polytrauma outpatient clinic were used in the analyses. Veterans whose cutoff scores exceeded an embedded validity scale (i.e., NSI Validity-10) or had missing data were excluded. Receiver Operating Curve (ROC) analysis was conducted to determine which item score (i.e., score of 0-4) on the NSI best classified the presence of anxiety as measured by a BAI cut-off score greater than 7 (i.e., mild anxiety).

There were 82 subjects who tested positive for anxiety based on a score of 3 on item 19 of the NSI. The ROC analysis was significant (AUC = .692, p < .001; 95% CI = .633 - .750). A score greater than 7 on the BAI yielded a sensitivity rate of .976 and a specificity rate of .711.
Conclusions
These results indicate that item 19 of the NSI is suggestive of a positive screen for mild anxiety in polytrauma samples with scores of 3 or greater indicating that further assessment of anxiety is recommended.

Abstract
Objective
The Neurobehavioral Symptom Inventory (NSI) is frequently used in the Department of Veterans Affairs as a self-report measure to assess for a variety of medical and mental health concerns in veterans who have suffered traumatic brain injury (TBI). Only one item on the NSI (item 20) relates to depressive symptoms (i.e., feeling depressed or sad). The purpose of the study was to compare responses on the Beck Depression Inventory-II (BDI-II) with item 20 of the NSI to determine classification for mild depressive symptomatology.
Method
Retrospective data collected from veteran patients (N = 325) of a polytrauma outpatient clinic were used in the analysis. Veterans were excluded if cutoff scores exceeded an embedded validity scale (i.e., NSI Validity-10) or had missing data. Receiver Operating Curve (ROC) analysis was conducted to determine which item score (i.e., score of 0-4) on the NSI best classified the presence of depressive symptoms as measured by a BDI-II cut-off score greater than 13 (i.e., mild depression).
Results
There were 55 subjects who tested positive for depression based on a cut-off score of 3 on the NSI. The ROC analysis was significant (AUC = .822, p < .001; 95% CI = .774 - .871). A cut-off score of greater than 13 on the BDI-II yielded a sensitivity rate of .982 and a specificity rate of .607.
Conclusions
These results indicate that item 20 of the NSI is indicative of a positive screen for depressive symptomatology with scores of 3 or greater indicating that further evaluation for depression is warranted.

Abstract
IntroductionSuicidal behaviour and drug and alcohol dependence represent two different aspects of self-destructive behavior.ObjectivesWe evaluated the relationship between suicidal behavior and substance and alcohol addiction. It was investigated the role of childhood trauma in these self-destructive behaviors and in the development of the two mental constructions of hopelessness and mentalization.AimsWe also assessed how a high level of hopelessness could affect suicidal ideation and how low or absent capacity of mentalization could influence the development of substance and/or alcohol addiction.MethodsThis naturalistic, observational study included 50 patients (mean age = 46.54; S.D = 14.57) recruited from the department of psychiatry (n = 18) and the centre for suicide prevention (n = 32) of Sant’Andrea Hospital (Rome). Different questionnaires were administered to each patient from February to May 2016.ResultsThere was not a statistically significant relationship between suicidal behavior and addict behavior. Childhood trauma resulted a risk factor for alcohol abuse with a relationship that tended to significance (P = 0.07). Physical and sexual abuses were significantly associated with addiction (respectively P = 0.014; P = 0.033). It was showed a statistically significant interaction between high level of hopelessness and suicidal ideation (P = 0.037). The absence of mentalization was related to the absence of alcohol abuse (P = 0.061). Finally, trauma experienced during childhood was associated with high level of hopelessness (P = 0.005).ConclusionsSuicidal behavior is influenced indirectly by a childhood traumatic experience that conditioning the level of hopelessness. Childhood trauma affected directly the development of drug abuse and alcoholism. The capacity of mentalization was not related with childhood trauma.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
We discuss the thermodynamics of closed quantum systems driven out of equilibrium by a change in a control parameter and undergoing a unitary process. We compare the work actually done on the system with the one that would be performed along ideal adiabatic and isothermal transformations. The comparison with the latter leads to the introduction of irreversible work, while that with the former leads to the introduction of inner friction. We show that these two quantities can be treated on an equal footing, as both can be linked with the heat exchanged in thermalization processes and both can be expressed as relative entropies. Furthermore, we show that a specific fluctuation relation for the entropy production associated with the inner friction exists, which allows the inner friction to be written in terms of its cumulants.

Abstract
Core-hole induced electron excitations in fullerene molecules, and small-diameter conducting carbon nanotubes, are studied using density functional theory with minimal, split-valence, and triply-split-valence basis sets plus the generalized gradient approximation by Perdew-Burke-Ernzerhof for exchange and correlation. Finite-size computations are performed on the carbon atoms of a C(60) Bucky ball and a piece of (3, 3) armchair cylindrical network, terminated by hydrogen atoms, while periodically boundary conditions are imposed on a (3, 3) nanotube unit cell. Sudden creation of the core state is simulated by replacing a 1s electron pair, localized at a central site of the structures, with the effective pseudo-potentials of both neutral and ionized atomic carbon. Excited states are obtained from the ground-state (occupied and empty) electronic structure of the ionized systems, and their overlaps with the ground state of the neutral systems are computed. These overlaps enter Fermi's golden rule, which is corrected with lifetime and finite-temperature effects to simulate the many-electron response of the nanoobjects. A model based on the linked cluster expansion of the vacuum persistence amplitude of the neutral systems, in a parametric core-hole perturbation, is developed and found to be reasonably consistent with the density functional theory method. The simulated spectrum of the fullerene molecule is found to be in good agreement with x-ray photoemission experiments on thick C(60) films, reproducing the low energy satellites at excitation energies below 4 eV within a peak position error of ca. 0.3 eV. The nanotube spectra show some common features within the same experiments and describe well the measured x-ray photoelectron lineshape from nanotube bundles with an average diameter of 1.2 nm.

Abstract
Hand chondroma is a particular cartilagineous tumour, being clinically benign, but morphologically malignant. This study investigates the expression of VEGF together with other growth factors and proliferation markers such as TGFβ2, Ki-67, TNF, FGF1, P53 in 8 cases of hand chondroma treated with courettage, in order to define the ethiopathogenesis of this tumour and the clinical significance of the resulting immunohistochemical profile, with particular respect to angiogenesis. VEGF was expressed in all cases; 5 cases were positive for TFGβ2 and 3 for PDGF. None of the other factors was expressed. On the basis of histologic results a specific model of tumour progression based on the indicators of angiogenesis could be related to hand tumours, in which VEGF expression should be the first stadium of the tumour aggressiveness, and the following PDGF, TGF 2 expression should be accompanied with a morphological outline worsening. Nevertheless the non constant expression of these indicators and the absent expression of proliferated indicators can explain the scant tendency to the relapse in presence of accurate curettage. It is important to remember that the cellular polymorphism typical of the cartilaginous tumours does not allow the application of an only oncogenesis model.

Abstract
Auger core-valence-valence transitions from single wall Carbon nanotubes are studied using a tight-binding calculational scheme with nearest neighbor overlap, hopping interactions, and a double-zeta basis set. The resulting Hamiltonian approximates the unperturbed pi and sigma bands of the nanomaterials coupled with the free electron states outside the solid and the core-hole. As a first step, the Fermi's golden rule is applied to determine the so called one-electron spectrum of emitted electrons from different tubes, in which either the neutralizing or the ejected electrons, in the initial state, lie within nearest neighboring atomic sites to the core-hole. Many-body corrections are effectively modeled using a broadening function, which accounts for dynamic screening effects involving the initial and final states. Particular attention is paid to the asymmetric component of the broadening function, responsible for the shake-up of pi electrons. Finally, the Cini-Sawatzky distortion function is used to describe the final state effect of the hole-hole interaction. A quantitative estimation of the interplay of shake-up processes is proposed by adjusting the asymmetric parameters of the broadening function to reproduce measurements of Auger electrons ejected from bundles of single wall Carbon nanotubes.

Abstract
Resonant neutralization of hyperthermal energy Na(+) ions impinging on Cu(100) surfaces is studied, focusing on two specific collision events: one in which the projectile is reflected off the surface, the other in which the incident atom penetrates the outer surface layers initiating a series of scattering processes, within the target, and coming out together with a single surface atom. A semi-empirical model potential is adopted that embeds: (i) the electronic structure of the sample, (ii) the central field of the projectile, and (iii) the contribution of the Cu atom ejected in multiple scattering events. The evolution of the ionization orbital of the scattered atom is simulated, backwards in time, using a wavepacket propagation algorithm. The output of the approach is the neutralization probability, obtained by projecting the time-reversed valence wavefunction of the projectile onto the initially filled conduction band states. The results are in agreement with available data from the literature (Keller et al 1995 Phys. Rev. Lett. 75 1654) indicating that the motion of surface atoms, exiting the targets with kinetic energies of the order of a few electronvolts, plays a significant role in the final charge state of projectiles.

Abstract
There is growing interest in osteoinductive agents for fracture healing especially in patients with non-union or delayed-union fractures. The aim of the present study is the assessment of the association of Vitamins D3 and K1 on proliferation and differentiation of human mesenchymal stem cells (hMSCs) derived from fracture sites in view of a possible clinical use. The synergic effect of Vitamin D3 and Vitamin K2 in preventing osteoporosis has been documented in clinical practice; however no reports investigating this association for fracture healing are present. Our data show a different outcome on cell proliferation linked to the different timing of drug administration as well as a synergic effect of the two vitamins on cell differentiation. The high level of osteocalcin and carboxylated osteocalcin detected in hMSCs treated with the association of the two vitamins in comparison with controls and with single vitamin administration underline the differentiation of these cells into osteoblastic phenotype. Our results indicate for the first time that vitamin D3 and K1 association is able to modulate in vitro the differentiation towards osteoblastic phenotype of hMSCs derived from fracture sites, thus offering clinicians a promising and low-cost strategy for reparative osteogenesis.

Abstract
Myogenic cells can be transformed in vitro by the introduction of several exogenous viral oncogenes. Transformed myoblasts are prevented from terminal differentiation into myotubes by the continuous expression of oncogenes such as myc and src, chosen as prototypes of nuclear and cytoplasmic oncogenes. A comparative analysis of the relationship between transformation and differentiation in myoblasts and cells belonging to other lineages has led to the proposal that terminal differentiation of myc-transformed quail myoblasts is indirectly prevented by the loss of growth control and that myc-bearing cells remain susceptible to growth regulation by interaction with adjacent normal cells. On the contrary, the src oncogene appears to affect expression of the myogenic programme via a direct mechanism, independent from abnormal growth control. There is increasing evidence for the existence of master regulatory genes that govern and influence muscle development in vivo and myogenic differentiation in vitro. Expression of cytoplasmic oncogenes such as src, ras and polyoma middle T in the mouse myogenic cell line, C2, results in inhibition of biochemical differentiation and a marked down-regulation of the MyoD1 and myogenin genes.

Abstract
In this study, we delineate the intracellular signalling pathways modulated by a conditional v-Src tyrosine kinase that lead to unrestrained proliferation and block of differentiation of primary avian myoblasts. By inhibiting Ras-MAPK kinase and phosphatidylinositol 3-kinase with different means, we find that both pathways play crucial roles in controlling v-Src-sustained growth factor and anchorage independence for proliferation. The Ras-MAPK kinase pathway also contributes to block of differentiation independently of cell proliferation since inhibition of this pathway both in proliferating and growth-arrested v-Src-transformed myoblasts induces expression of muscle-specific genes, fusion into multinucleated myotubes and assembly of specialized contractile structures. Importantly, we find that the p38 MAPK pathway is inhibited by v-Src in myoblasts and its forced activation results in growth inhibition and expression of differentiation, indicating p38 MAPK as a critical target of v-Src in growth transformation and myogenic differentiation. Furthermore, we show that downregulation of p38 MAPK activation may occur via Ras-MAPK kinase, thus highlighting a cross-regulation between the two pathways. Finally, we report that the simultaneous inhibition of MAPK kinase and calpain, combined to activation of p38 MAPK, are sufficient to reconstitute largely the differentiation potential of v-Src-transformed myoblasts.

Abstract
INTRODUCTION Soft tissue is a rare localization of carcinoma metastasis. Skeletal muscle is considered the most frequent site. The aim of this paper is to report a very rare localization of soft-tissue metastasis of lung adenocarcinoma in the lower leg interosseous membrane, surgically treated at our department. MATERIALS AND METHODS A 66-year-old man with a history of lung adenocarcinoma was admitted to our department because he complained of a pain resistant to drugs that had persisted for 1 month. Imaging showed that the lesion was unique, localized in the interosseous membrane, with a distal margin more than 2 cm above the ankle platform. A distal fibula resection, including the tumour and a reconstruction according to Capanna type A2 was performed. RESULTS At the 6 months follow-up, the patient was walking without external support. CONCLUSION Surgery is not the treatment of choice for soft-tissue metastases, but it may be recommended when the lesion is unique and inducing a pain resistant to anti-inflammatory drugs.

The management of bone metastases includes the removal of gross disease and the administration of local adjuvants. We have investigated the possibility of adding antiblastic drugs to acrylic cement. Cylinders of acrylic cement were manufactured containing three different antiblastic drugs, methotrexate, cisplatin and doxorubicin. We performed in vitro analysis on MCF-7 human breast cancer cells in order to evaluate the biological effect of the mixtures and surface analysis of the acrylic cement-cisplatin cylinders using energy-dispersive x-ray analysis (EDAX). All drugs were released in an active form from the cement. Each drug had a different effect on cell viability. Doxorubicin had the greatest effect on breast cancer cells. Surface analysis showed that antiblastic drugs were present in the form of granules. These results confirm the potential of antiblastic-loaded cement as a possible adjuvant in the local treatment of bone metastases. Further studies should be undertaken to determine whether the release of antiblastic drugs from cement is elution or if they are only released from the surface.

Abstract
Sixteen 2- to 3-year-old sheep were submitted to a hemiarthroplasty of the hip joint with a specially designed femoral component. The proximal two thirds of the stem had a circumferential, plasma-sprayed, porous coating with hydroxyapatite. The animals where killed a 15, 30, 60, 90, 120, 180, 200, 270, 360, and 540 days after surgery. Femurs were submitted to plain radiographs, computerised tomography (CT) scan, and dual energy X-ray absorptiometry (DEXA). Cross-sections were obtained at four different levels and studied using scanning electron microscopy. In the coated portion of the stem, apposition of woven immature bone was evident at 15-30 days and mature lamellar bone by 30 days. With time, the gap between the endosteum and the coated surface was filled by bridges of lamellar bone with a marked trabecular orientation. In the distal uncoated portion of the stem, the implant was initially surrounded by fibrous tissue that, with time, transformed into lamellar bone.

Abstract
Over the last decade, the development, evaluation, and use of multiphase-flow-metering (MFM) systems have been a major focus for the oil and gas industry worldwide. Many alternative metering systems have been developed, but none can be referred to as generally applicable or universally accurate. Both established and novel technologies suitable to measure the flow rates of gas, oil, and water in three-phase flow are reviewed and assessed within this framework. Technologies already implemented in various commercial meters then are evaluated in terms of operational and economical advantages or shortcomings from an operator's point of view. The lessons learned about the practical reliability, accuracy, and use of available technology are discussed. As operators now realize, use of MFM systems (MFMSs) is essential in exploiting marginal fields. A new approach to flow assurance, deepwater developments, downhole/seabed separation systems, and wet-gas fields is foreseen. The authors suggest where additional research to develop the next generation MFM devices will be focused to meet the as yet unsolved problems.
Brief History
The first commercial MFMSs appeared approximately 10 years ago, as a result of several multiphase metering research projects in the early 1980s. The driving force to develop MFM technology was the forecast decline of production from the major North Sea fields, accompanied by the necessity to tie backfuture smaller discoveries to existing infrastructure. Increasing gas and waterfractions, inherent in a mature producing province, would create more-unstable flow conditions in existing production facilities and require more-flexible multiphase solutions.
In less than a decade, MFM has become accepted in the field and is beginning to be considered as a primary metering solution for new field developments.
MFM Applications
Within the oil and gas industry, it is generally recognized that MFM could lead to great benefits in terms of the following.1,2,3
Layout of Production Facilities.
The use of MFMs reduces the hardware needed for onshore, offshore topside, and offshore subsea applications. Of primary importance is the removal of a dedicated test separator for well-testing applications. Use of MFM (with its smaller footprint) for topside applications minimizes platform space and load requirements for well-testing operations. Finally, costly well-testing lines can be stripped from the production facilities, which may be of vital importance for unmanned locations, deepwater developments, and satellite fields.
Well Testing.
Conventional test separators are expensive and require much time to monitor each well's performance because of the time required to reach stabilized flow conditions. It is particularly important in deepwater developments, because of the exceptional length of the flowlines. In such cases, production from individual wells connected to the same manifold may be monitored by use of a dedicated test line to avoid shutting down all the wells, then testing them one by one (with considerable production loss). However, the expense of a separate flowline may be prohibitive, hence the advantages of MFM installed in the subsea manifold. Test separators have an accuracy between approximately 5 and10% (currently achievable with MFMSs) but require regular intervention by trained personnel and cannot provide continuous well monitoring. Another disadvantage of conventional well testing with conventional separators is that well performance suffers after shutdown cycles related to well testing. Often, wells tested on a regular basis require more-frequent workovers to maintain their production rates.
Use of MFMSs for exploration-well testing4 provides satisfactory flow measurements without separation of the phases. It is claimed that they can be used to monitor the well during its cleanup flow (traditionally, this flow information is lost because the well stream is not directed through the test separator). Added value is represented by improved control of the drawdown applied to the formation, the pressure transient, and shortened flow periods.
Reservoir Management.
MFMSs provide real-time, continuous data to enable operators to characterize field and reservoir performance better and react faster. Changes in gas/oil ratio or water cut can be detected and quantified immediately, where as traditional test separators provide information about only cumulative volumes at discrete points in time.

Abstract
Six series of N-acyl-N-phenyl ureas 1-6 of piperidine (1), and 2-ethyl- (2), 3-methyl- (3), 4-methyl- (4), 4-phenyl- (5), cis-2,6-dimethyl- (6) piperidine were synthesised and evaluated for their anti-inflammatory, anaesthetic, anti-pyretic properties. Some derivatives of series 1 and 5 were also assayed for anti-proliferative activity. Several compounds showed an anti-inflammatory activity comparable or slighty inferior to that of indomethacin in rats (1c,d, 2a,b,g,h, 3b, 4h, 5d,e). Moreover, an appreciable anti-inflammatory activity was also found in 2c,e, 3e,f,g, 4g, 5a,b,c,f,h, and 6a,b,d. All the compounds were devoid of anti-pyretic activity and only a few of them exhibited a low level of infiltration anaesthesia in mice. Compound 5a showed a broad spectrum anti-cancer activity (at low micromolar concentrations), particulary significant against leukemia subpanel.

Abstract
Two series of 3-arylsulphonyl-5-arylamino-1,3,4-thiadiazol-2(3H)ones 2 with potential anti-inflammatory and analgesic activity were prepared and tested. Pharmacological results revealed that all the title compounds, endowed with an arylsulphonyl side chain, possess good antalgic activity and fair anti-inflammatory properties. The analgesic profile of the two series, evaluated by the acetic acid writhing test, showed that compounds 2c, 2f and 2h, in particular, were the most active. Structure-activity relationships are briefly discussed.

Abstract
The synthesis of analogues of N,2-diphenyl-N-(4-piperidyl)acetamide endowed with antiarrhythmic activity is reported. Benzoyl, cinnamoyl, acetyl and propionyl groups replace the phenacyl group as N-acyl substituent, while pyridine replaces benzene as aromatic ring bound to the amide nitrogen. The title compounds were evaluated for antiarrhythmic activity on experimental arrhythmias induced by aconitine in rats. The presence of a n-propyl chain and an unsubstituted cinnamoyl moiety (1j) gives the highest protection against aconitine induced extrasystoles while the best efficacy against lethal effects is due to the presence of a n-propyl chain and an acetyl moiety (1m).

Abstract
Clinical tolerance to the acute effects of zinc oxide inhalation develops in workers during periods of repeated exposure. The aims of this study were to determine whether clinical tolerance is accompanied by a reduction in the acute pulmonary inflammatory and cytokine responses to zinc oxide exposure and whether tolerance can be demonstrated in sheet metal workers who chronically inhale low levels of zinc oxide. Naive (never-exposed) subjects inhaled 5 mg/m3 zinc oxide on 1 or 3 days and underwent bronchoalveolar lavage 20 hours after the final exposure. Sheet metal workers inhaled zinc oxide on 1 day and control furnace gas on another day. Among naive subjects in whom tolerance was induced, bronchoalveolar lavage fluid percent neutrophils and interleukin-6 (IL-6) levels were significantly decreased compared with subjects who underwent only a single exposure. Sheet metal workers were much less symptomatic, but they still experienced a significant increase in plasma IL-6. The results indicate that clinical tolerance to zinc oxide is accompanied by reduced pulmonary inflammation and that chronically exposed sheet metal workers are not clinically affected by exposure to zinc oxide fume at the Occupational Safety and Health Administration Permissible Exposure Limit. The increase in IL-6 levels observed in the clinically responsive, and to a lesser extent, tolerant, states following zinc oxide inhalation is consistent with the dual role of IL-6 as a pyrogen and anti-inflammatory agent.

Abstract
A series of indazoloxypropanolamines 7 and 8, pindolol isosteres, were synthesized to extend the structure activity relationship (SAR) which was observed in an earlier series of related derivatives. Compounds 7, characterized by methyl substitution on the N-1 indazole nucleus, generally exhibited significant antiarrhythmic, local anaesthetic and analgesic activities. The preliminary radioligand binding assay highlighted, in compounds 7, an interesting beta 1-affinity which can be well correlated to their antiarrhyhtmic activity. Analogues 8 characterized by a phenyl group on the N-1 indazole nucleus, were generally less active as antiarrhyhtmic agents but generally interesting as local anaesthetics. Due to the importance of the indazole moiety as a carrier of antiphlogistic activity, the two classes of derivatives 7 and 8 were evaluated for their NSAID behaviour. Once again, compounds 7 resulted having more interesting analgesic and antipyretic effects than analogues 8.

Abstract
Data concerning patients undergoing antibiotic treatment for upper (URTI) or lower (LRTI) respiratory tract infections were collected from 23 General Practitioners (GPs) in the Campania Region of Italy from November 15, 1997 to March 15, 1998. The objectives of the study were: a) to assess the occurrence of URTIs and LRTIs; b) to document the factors that influence GPs' choice of therapy; c) to correlate antibiotic choice with duration and outcome of treatment; d) to assess the incidence of unwanted effects. 2198 questionnaires were collected. Patients were +/-43.9 of age. URTIs were diagnosed in 65.4% and 34.6% LRTIs. The mean duration of antibiotic treatment was 4.5 days in URTIs and 5.6 days in LRTIs. The choice of antibiotic treatment was influenced by clinical assessment of infections (67.1%). The most commonly used antibiotic categories in URTIs were macrolides (39.3%), penicillins (27.4%) and cephalosporins (23.8%) whereas for LRTIs mainly cephalosporins (63.8%), penicillins (9.2%) and fluoroquinolones (7.4%) were used. Adverse events were experienced by 3.9% of patients.

Abstract
A series of substituted N-cycloalkyl benzamides, cinnamamides, and indole-3-carboxamides were synthesized and evaluated for their analgesic, antiinflammatory activities as well as for their gastrointestinal irritation liability. Indomethacin was used as reference drug in both tests. Compounds 1k, 1b, 1h, 1j, and 1g were the most active in the antiinflammatory paw edema inhibition test, with a sharply dose-dependent effect. In terms of the analgesic activity (acetic acid writhing test), the most active compound was 5a followed by 3a, but many other compounds were found to have a non-negligible potency. Even in this case, the effect was dose dependent.

Abstract
Rho family GTPases have been implicated in the regulation of the actin cytoskeleton in response to extracellular cues and in the transduction of signals from the membrane to the nucleus. Their role in development and cell differentiation, however, is little understood. Here we show that the transient expression of constitutively active Rac1 and Cdc42 in unestablished avian myoblasts is sufficient to cause inhibition of myogenin expression and block of the transition to the myocyte compartment, whereas activated RhoA affects myogenic differentiation only marginally. Activation of c-Jun N-terminal kinase (JNK) appears not to be essential for block of differentiation because, although Rac1 and Cdc42 GTPases modestly activate JNK in quail myoblasts, a Rac1 mutant defective for JNK activation can still inhibit myogenic differentiation. Stable expression of active Rac1, attained by infection with a recombinant retrovirus, is permissive for terminal differentiation, but the resulting myotubes accumulate severely reduced levels of muscle-specific proteins. This inhibition is the consequence of posttranscriptional events and suggests the presence of a novel level of regulation of myogenesis. We also show that myotubes expressing constitutively active Rac1 fail to assemble ordered sarcomeres. Conversely, a dominant-negative Rac1 variant accelerates sarcomere maturation and inhibits v-Src-induced selective disassembly of I-Z-I complexes. Collectively, our findings provide a role for Rac1 during skeletal muscle differentiation and strongly suggest that Rac1 is required downstream of v-Src in the signaling pathways responsible for the dismantling of tissue-specific supramolecular structures.

Abstract
We report a case of a spleen infarction caused by the vascular pedicle torsion. A 25 year-old-man, heterozygous for HbS, presented with severe abdominal pain especially in the left upper quadrant in front and in the back, fever other symptoms related to acute abdomen. First we excluded most common disease (occlusive one and hematologic one) through conform investigation, then we suspected a spleen problem. So we did further investigation with ultrasonography which showed splenomegaly and the spleen looked twisted with its hilum in contact with previous abdominal wall, moreover (here were are as of decreased signal intensity characteristic of splenic infarction under the capsule and some blood in the Douglas pouch. The patient underwent splenectomy urgently. During the intervention we saw a splenomegaly like the ultrasonography showed, moreover there were a long twisted vascular pedicle and many areas of infarctions, some of which had ruptured causing emoperitoneum. The surgical intervention was successful and the clinical spectrum was solved. The splenic infarction might be clinically silent or to represent a surgical emergency. In front a case of acute abdomen, after exclusion of most common etiology, we underline the importance to suspect a spleen suffering, especially vascular one, when (here was no history of trauma. Considering this fact, a simple not invasive examination like ultrasonography is able to confirm this kind of hypothesis and to give soon information to make the surgical choose.

Abstract
Two series of N-[4-(alkyl)cyclohexyl]-substituted benzamides, i.e. a series of N-[4-(tert-butyl)cyclohexyl]-substituted benzamides and a series of N-[4-(ethyl)cyclohexyl]-substituted benzamides, were synthesised and evaluated for their anti-inflammatory and analgesic potencies, and gastrointestinal irritation liability.

Abstract
A series of pyrazole analogues of bifonazole, an antifungal drug used in clinical practice, 2a-h and 4a-h were synthesized and tested in vitro against Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus, with no significant results. Imidazoles 2a-h were also tested in vivo for antiarrhythmic and antihypertensive activities; two of these compounds showed moderate activity against ventricular fibrillation caused by aconitine in rats. The above compounds were prepared by reaction of phenyl-[5 substituted 1-phenyl (or 1-methyl)-1H-pyrazol-4-yl]methanols with N,N'-carbonyldiimidazole (2a-h) or of the respective chloro derivatives with 1H-1,2,4-triazole (4a-h).

Abstract
Telomerase activity is detectable in the majority of tumors or immortalized cell lines, but is repressed in most normal human somatic cells. It is generally assumed that reactivation of telomerase prevents the erosion of chromosome ends which occurs in cycling cells and, hence, hinders cellular replicative senescence. Here, we show that the expression of v-Myc oncoprotein by retroviral infection of telomerase-negative embryonal quail myoblasts and chicken neuroretina cells is sufficient for reactivating telomerase activity, earlier than telomere shortening could occur. Furthermore, the use of a conditional v-Myc-estrogen receptor protein (v-MycER) causes estrogen-dependent expression of detectable levels of telomerase activity in recently infected chick embryo fibroblasts and neuroretina cells. We conclude that the high levels of telomerase activity in v-Myc-expressing avian cells are not the mere consequence of transformation or of a differentiative block, since v-Src tyrosine kinase, which prevents terminal differentiation and promotes cell transformation, fails to induce telomerase activity.
