Abstract
Most of the current assays directed at the investigation of HIV reactivation are based on cultures of infected cells such as Peripheral Blood Mononuclear Cells (PBMCs) or isolated CD4+ T cells, stimulated in vitro with different activator molecules. The culture media in these in vitro tests lack many age- and donor-specific immunomodulatory components normally found within the autologous plasma. This triggered our interest in understanding the impact that different matrices and cell types have on T cell transcriptional profiles following in vitro culture and stimulation. METHODS Unstimulated or stimulated CD4+ T cells of three young adults with perinatal HIV-infection were isolated from PBMCs before or after culture in RPMI medium or autologous plasma. Transcriptomes were sequenced using Oxford Nanopore technologies. RESULTS Transcriptional profiles revealed the activation of similar pathways upon stimulation in both media with a higher magnitude of TCR cascade activation in CD4+ lymphocytes cultured in RPMI. CONCLUSIONS These results suggest that for studies aiming at quantifying the magnitude of biological mechanisms under T cell activation, the autologous plasma could better approximate the in vivo environment. Conversely, if the study aims at defining qualitative aspects, then RPMI culture could provide more evident results.

Abstract
Ecotoxicological and pathological research on Grampus griseus (Cuvier, 1812) (Risso's dolphins) is scarce both globally and in the Mediterranean Sea. This species has been classified as "Vulnerable" by the International Union for Conservation of Nature (IUCN) in the Mediterranean Sea. To evaluate the presence of "persistent organic pollutants" (POPs), especially organochlorine compounds (OCs), in the animals, chemical analyses were performed on tissues and organs of Risso's dolphin stranded along the Italian coasts between 1998 and 2021. Toxic contaminants such as hexachlorobenzene (HCB), polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane and its metabolites (DDTs) were examined in the blubber, liver, muscle, and brain of 20 animals, and data was correlated with sex, age, and stranding locations.

Abstract
BACKGROUND Papillary thyroid cancer (PTC) is the most frequent thyroid tumor. The tissue inhibitor of metalloproteinase-3 (TIMP3) gene encodes a matrix metalloproteinases inhibitor that exerts a tumor suppressor role in several tumor types. TIMP3 is frequently downregulated in PTC by promoter methylation. We have previously functionally demonstrated that TIMP3 exerts an oncosuppressor role in PTC: TIMP3 restoration in the PTC-derived NIM1 cell line affects in vitro migration, invasion and adhesive capability, while reduces tumor growth, angiogenesis and macrophage recruitment in vivo. To get a deeper insight on the mediators of TIMP3 oncosuppressor activity in thyroid tumors, here we focused on the TIMP3 related transcriptome. METHODS TCGA database was used for investigating the genes differentially expressed in PTC samples with low and high TIMP3 expression. Genome wide expression analysis of clones NIM1-T23 (expressing a high level of TIMP3 protein) and NIM1-EV (control empty vector) was performed. Gene sets and functional enrichment analysis with clusterProfiler were applied to identify the modulated biological processes and pathways. CIBERSORT was used to evaluate the distribution of different immunological cell types in TCGA-PTC tumor samples with different TIMP3 expression levels. Real time PCR was performed for the validation of selected genes. RESULTS Thyroid tumors with TIMP3-high expression showed a down-modulation of inflammation-related gene sets, along with a reduced protumoral hematopoietic cells fraction; an enrichment of cell adhesion functions was also identified. Similar results were obtained in the TIMP3-overexpessing NIM1 cells in vitro model, where a down-regulation of immune-related function gene sets, some of which also identified in tumor samples, was observed. Interestingly, through enrichment analysis, were also recognized terms related to cell adhesion, extracellular matrix organization, blood vessel maintenance and vascular process functions that have been found modulated in our previous in vitro and in vivo functional studies. CONCLUSIONS Our results highlight the correlation of TIMP3 expression levels with the regulation of inflammatory functions and the immune infiltration composition associated with different PTC prognosis, thus providing a broader view on the oncosuppressor role of TIMP3 in PTC.

Abstract
The term "street furniture" indicates objects mostly made of cast iron alloys and aimed to improve the quality of life in urban settlements, such as street lamps, fountains and gazebos. These objects are often ancient and relevant as cultural heritage. Despite the constant presence of street furniture in urban settlements, studies of its evolution along centuries are limited. Since functional aspects have been often considered prevalent against artistic and historical values, many objects have been considered obsolete, thus replaced or re-melted. Street furniture rarely received attention by scholars, and studies on this topic have been often incomplete. This study reviews the history of street furniture made of cast iron (CI street furniture), first examining the reasons behind the choice of this material, closely related to its diffusion during the First Industrial Revolution. The review discusses the relationship between CI street furniture and cultural heritage based on artistic, aesthetic and ethical issues, also examining historical catalogs. The development of CI street furniture in United Kingdom, France and Italy is reported, together with their local aspects. The production technique is discussed and the importance of preservation of CI street furniture is highlighted, emphasizing the need for globally planned interventions in this field.

Abstract
AIMS MSP1A and MSP1B polymorphic sites located in the GH genomic area have been found associated with GH response to insulin stimulation, with familiar short stature and with age at onset of Type 2 Diabetes (T2D). These observations prompted us to search for a possible relationship between stature and age at onset of the disease. METHODS We have reexamined the data of 272 subjects with T2D mellitus. RESULTS There is a highly significant negative correlation between stature and age at onset in non obese females (p < 0.001) but not in obese females and in males. In non obese females with stature within the first quartile the mean age at onset is 62 years while in those with a stature greater than the first quartlile the mean age at onset is 52 yesrs (p < 0.001). No difference is observed in obese females and males. CONCLUSIONS These observations suggest the existence of different mechanisms underlying susceptibility to T2D. In addition to the well known increased risk due to obesity, endocrine dysfunctions related to genetic variability within the GH genomic area could represent another mechanism operating in non obese females. A cluster of non obese women characterized by short stature and late onset of diabetes seems to be separated by this mechanism from other women.

Abstract
Adenosine modulates cardiovascular functions reducing blood pressure and heart rate. Adenosine deaminase (ADA) by the irreversible deamination of adenosine to inosine contributes to the regulation of adenosine concentration in body fluids. We have studied the interaction between smoking and ADA genetic variability concerning their effects on blood pressure. We have studied 344 subjects admitted to the hospital for cardiovascular diseases. The genotypes of two polymorphic loci within the ADA gene were determined: ADA1 and ADA2. Both loci show two alleles: ADA1*1 and ADA1*2 in ADA1 locus and ADA2*1 and ADA2*2 in ADA2 locus. In the absence of smoking, the proportion of subjects with hypertension tends to be lower in carriers of the ADA1*2 allele. In smoking subjects, the pattern is reversed and the proportion of those with hypertension tends to be higher in carriers of the ADA1*2 allele. A similar pattern is observed for ADA2 locus. Smoking increases the proportion of subjects showing hypertension: such effect is more marked in those carrying the ADA1*2 allele as compared to subjects with ADA1*1/*1 genotype. The same pattern of association is observed for ADA2 locus. The two loci show an additive effect. The odds ratio for hypertension in smokers vs nonsmokers is 1.450 in subjects carrying ADA1*1/*1 and ADA2*1/*1 genotypes, while it is 11.200 in subjects carrying the *2 alleles in both loci. From a practical point, a view of our results suggest that smokers carrying both ADA1*2 and ADA2*2 alleles have a higher risk of hypertension.

Abstract
OBJECTIVES The aim was to investigate an outbreak of invasive meningococcal disease (IMD) in Southern Sardinia. METHODS Epidemiological and microbiological investigations were performed. The latter included antimicrobial susceptibility testing and whole-genome sequencing (WGS). RESULTS Seven individuals with severe IMD were found to be infected with serogroup B (MenB) Neisseria meningitidis in the first quarter of 2018. Five of the seven cases (five males; mean age 19 years; range 18-21 years; CFR 40%) were due to a unique strain B:P1.5-1,10-8:F3-6:ST-11(cc11), probably switched from the hypervirulent C-cc11, as confirmed by WGS. All five patients had attended the same nightclub in the 2 weeks prior to symptom onset. Public health measures, including chemoprophylaxis of contacts and active immunization against MenB, were implemented. CONCLUSIONS We observed five IMD cases due to the same switched MenB strain. The hypervirulent B:P1.5-1,10-8:F3-6:ST-11(cc11) strain, probably switched from C-cc11, is of concern due to the observed high virulence and case fatality rates. All the patients shared the same place of probable exposure. The molecular characterization of the invasive strain allowed the outbreak to be confirmed, which was then controlled through timely public health action.

Abstract
Radon exposure is the second leading risk factor for lung cancer among smokers and the leading risk factor among non-smokers. Radon concentrated in lower levels of homes/buildings can be reduced if found, thus lowering lung cancer risk. The objective of this study was to measure radon knowledge in diverse populations, with varying radon-related laws, to inform radon-related cancer control practices and activities. A survey was mailed to 3000 homebuyers who purchased single-family homes; 995 responses (33%) were received. Overall, 86% of respondents heard of radon-related health issues. Real estate agents (69%) or home inspectors (65%) were the most common sources of information. Respondents were more likely to test their home for radon if they reported previously hearing of radon-related health issues or understanding of how radon-related health issues affect the home-buying process. Respondents in states with notification policies were twice as likely as those without policies to have heard about radon-related health issues (OR 2.01, 95% CI: 1.27-3.17). This study provides useful information for cancer control activities including that education is positively associated with home testing for radon. It also suggests partnering with real estate agents to further radon education and testing efforts to reduce radon exposure and lung cancer risk.

Abstract
Long non-coding RNAs (lncRNAs) represent a novel class of functional RNA molecules with an important emerging role in cancer. To elucidate their potential pathogenetic role in chronic lymphocytic leukemia (CLL), a biologically and clinically heterogeneous neoplasia, we investigated lncRNAs expression in a prospective series of 217 early-stage Binet A CLL patients and 26 different subpopulations of normal B-cells, through a custom annotation pipeline of microarray data. Our study identified a 24-lncRNA-signature specifically deregulated in CLL compared with the normal B-cell counterpart. Importantly, this classifier was validated on an independent data set of CLL samples. Belonging to the lncRNA signature characterizing distinct molecular CLL subgroups, we identified lncRNAs recurrently associated with adverse prognostic markers, such as unmutated IGHV status, CD38 expression, 11q and 17p deletions, and NOTCH1 mutations. In addition, correlation analyses predicted a putative lncRNAs interplay with genes and miRNAs expression. Finally, we generated a 2-lncRNA independent risk model, based on lnc-IRF2-3 and lnc-KIAA1755-4 expression, able to distinguish three different prognostic groups in our series of early-stage patients. Overall, our study provides an important resource for future studies on the functions of lncRNAs in CLL, and contributes to the discovery of novel molecular markers with clinical relevance associated with the disease.

Abstract
Deregulated microRNA (miR)/transcription factor (TF)-based networks represent a hallmark of cancer. We report here a novel c-Myc/miR-23b/Sp1 feed-forward loop with a critical role in multiple myeloma (MM) and Waldenstrom's macroglobulinemia (WM) cell growth and survival. We have found miR-23b to be downregulated in MM and WM cells especially in the presence of components of the tumor bone marrow milieu. Promoter methylation is one mechanism of miR-23b suppression in myeloma. In gain-of-function studies using miR-23b mimics-transfected or in miR-23b-stably expressing MM and WM cell lines, we observed a significant decrease in cell proliferation and survival, along with induction of caspase-3/7 activity over time, thus supporting a tumor suppressor role for miR-23b. At the molecular level, miR-23b targeted Sp1 3'UTR and significantly reduced Sp1-driven nuclear factor-κB activity. Finally, c-Myc, an important oncogenic transcription factor known to stimulate MM cell proliferation, transcriptionally repressed miR-23b. Thus MYC-dependent miR-23b repression in myeloma cells may promote activation of oncogenic Sp1-mediated signaling, representing the first feed-forward loop with critical growth and survival role in myeloma.

Abstract
BACKGROUND In Italy, the incidence of Invasive Meningococcal Disease (IMD) was around 0.28 per 100,000 over the last years. Since the risk IMD is usually high among infants aged less than 1 year, we decided to evaluate the trend of IMD cases reported between 2006 and 2014 in this age group. In particular, the study aim was to describe the main characteristics of IMD cases in infants following the introduction of MCC vaccine (2005) and to estimate the number of cases which are potentially preventable through early vaccination. METHODS The National Surveillance System of Bacterial Meningitis was established in 1994 and in 2007 was extended to all invasive bacterial diseases. Clinical data and isolates and/or clinical samples are collected from hospitalized patients throughout the country. IMD cases are reported by clinicians to the local health authorities, and samples are sent to the Reference Laboratory at the Istituto Superiore di Sanità for further characterization and storage at -80°C. In particular, serogroup identification is obtained by agglutination with commercial antisera or by multiplex PCR. RESULTS The annual incidence for infants <1 year old remained rather stable of 3.6 per 100,000, with several upward and downward oscillations and a peak in 2010. The incidence of IMD among infants was more than 10 times higher than the overall rate of IMD observed in Italy. Finally, serogroup B was more frequently detected among infants aged <1 year, accounting for 65% of the total (p<0.01). CONCLUSIONS During the study period, IMD incidence reported among infants aged less than one year old was 10 times higher than the overall rate, and serogroup B was the most commonly detected over time. The long-term impact of meningococcal C conjugate vaccine and the effect of the introduction of meningococcal B vaccination among infants need to be evaluated.

Abstract
AIM Hematopoietic stem cells (HSCs) and endothelial progenitor cells (EPCs) are known to play a role in the vascular responses and adaptations to exercise. We performed a quantitative assessment of HSCs and EPCs in adolescents in order to investigate whether resting levels of circulating HSCs and EPCs are comparable between elite athletes and sedentary healthy subjects. METHODS HSCs and EPCs levels were measured in adolescent competitive football players and in age- and sex-matched sedentary controls. A laboratory testing was also performed to determine the white blood cells count and the lipid profile. All athletes were evaluated at the same stage of their training program, after 6 months of training. Controls were not engaged in any kind of routine training program. RESULTS Twenty male competitive athletes (18.4 ± 0.5 years) and 9 sedentary controls (18.7 ± 0.4 years) participated in the study. As expected, HDL cholesterol was higher in athletes as compared with controls (P<0.05). No significant differences in the other laboratory parameters were observed among groups. Circulating levels of HSCs were significantly lower in athletes in comparison with sedentary controls (P<0.05). Conversely, EPCs and KDR+ cell subpopulations did not substantially differ between athletes and controls. CONCLUSION Adolescent athletes exhibit lower levels of circulating HSCs but not of EPCs compared to sedentary controls. The process of tissue repair associated with intensive training can contribute to this difference, acting as a stimulus for mobilization and homing of HSCs in the site of injuries.

Abstract
AIMS T1D has been found associated with PTPN22 and with ACP1-ADA1 joint genotype. In the present note we have collected further data to evaluate the relative importance of the two systems and to search for possible interaction of PTPN22 with ACP1-ADA1 joint genotype. METHODS We have studied 314 children with T1D and 770 controls from the White population of Central Italy. ACP1, ADA1 and PTPN22 genotypes were determined by DNA analysis. Chi square test of independence was performed by SPSS program and three way contingency analysis by a log-linear model. RESULTS Both carriers of *T allele of PTPN22 and subjects with ACP1 *A/*A and *A/*B genotypes carrying ADA1 *2 allele show an increase of susceptibility to T1D. There is evidence of additive effect (p=0.0002) but not of epistatic interaction. The association of T1D with ACP1-ADA1 joint genotype is stronger (OR=2.494, 95% C.I. 1.509-4.122) as compared to that with PTPN22 (OR=1.825, 95% C.I. 1.951-2.859). CONCLUSIONS It has been suggested that the *T variant of PTPN22 inhibits T cell receptor signaling leading to failure to delete autoreactive T cells during intrathymic selection resulting in increased susceptibility to autoimmune disorders. The joint genotype ACP1 *A/*A and *A/*B carrying the ADA1 *2 allele shows a decreased activity of ACP1 resulting in a lowering of Zap70 activity that may decrease T cell receptor signaling with an additive effects to the inhibition due to the *T variant of PTPN22.

Abstract
AIM In the last decade while many comparative studies examined hemostatic topics, adhesives and sealants, few clinical trials were made. We are focusing our attention particularly on TachoSil®, and studying its efficacy on reducing the frequency of anastomotic leakage, thought to be one of the causes of prolonged periods of patients' hospitalization. METHODS We examined 188 patients who underwent colorectal and enteric surgery at our department between January 2010 and March 2013. The efficacy of fibrin glue was evaluated on a cohort of patients at risk of anastomosis leakage. To test the relationship between the application of TachoSil® and the type of complications, a multiple logistic regression model was implemented. Fisher exact Test was used to compare the relations between two groups. The Mann-Whitney test was used to account for the days necessary for the follow-up of the patients in the various units participating in the study. RESULTS From the logistic regression model we can infer that TachoSil® is a highly protective factor though not statistically significant (OR=0.78; P>0.05). The results obtained analyzing the average days of patients hospitalization show a statistically significant decrease of such parameter in patients under treatment, especially those who underwent transverse colon resection (P<0.001). CONCLUSION The results of this study show that TachoSil® is a highly protective factor, but its efficacy is not statistically significant due to the small number of patients treated. It is important to call the attention to the reduced number of the hospitalization needed for the patients under treatment.

Abstract
Peritoneal carcinomatosis (PC) from gastric cancer is a condition with a very bleak prognosis. Most authors consider it to be a terminal disease and recommend palliative therapy only. Multimodal therapeutic approaches to PC have emerged in the last decades, combining cytoreductive surgery (CRS) and peritonectomy procedures with perioperative intraperitoneal chemotherapy (IPEC), including hyperthermic intraperitoneal chemotherapy (HIPEC) and/or early postoperative intraperitoneal chemotherapy (EPIC). We reviewed the pertinent literature concerning the HIPEC modality both for the treatment of established PC and the prevention of peritoneal recurrence after potentially curative gastric cancer (GC) surgery. Basically, the two procedures relate to different aspects of GC and they are not comparable, since the latter has been used as an adjuvant when PC is still not macroscopically evident and the former has been exclusively used in advanced gastric cancer stages with peritoneal dissemination. Data supporting beneficial effects once gastric PC is already manifest is scarce and limited to few centres with specific experience in this field. Conversely, with regards to the peritoneal perfusion for preventing PC in high risk gastric cancer patients, there are phase III trials and meta-analysis which support beneficial effects resulting from the HIPEC procedure. To offer a baseline guide, we summarized the actual status and general outcome obtained by this multimodal technique, in association or not with CRS as treatment of advanced GC.

Abstract
AIM Protein kinases, activated by vasodilator substances, affect vascular function by regulating large conductance Ca(2+) -activated K(+) (KCa 1.1) channels. Thus, the aim of the present investigation was to address the hypothesis that quercetin-induced vasorelaxation is caused by a PKG-mediated stimulation of KCa 1.1 currents. METHODS Single freshly isolated myocytes and endothelium-denuded rings of the rat tail main artery were employed for electrophysiological and contractility measurements respectively. RESULTS Quercetin relaxed vessels and increased KCa 1.1 currents in a concentration-dependent manner: both effects were antagonized by the specific KCa 1.1 channel blocker iberiotoxin. Stimulation of KCa 1.1 currents was fully reversible upon drug washout, markedly reduced by Rp-8-Br-PET-cGMPs, a PKG-inhibitor, but not affected by catalase. Quercetin shifted by 34.3 mV the voltage dependence of KCa 1.1 channel activation towards more negative membrane potentials without affecting its slope. Under conditions of tight functional coupling between sarcoplasmic reticulum Ca(2+) release sites and KCa 1.1 channels, quercetin decreased both the frequency and the amplitude of KCa 1.1 transient currents in a ryanodine-like manner. CONCLUSION The natural flavonoid quercetin relaxes the rat tail main artery partly via a PKG-mediated stimulation of smooth muscle KC a 1.1 channels.

Abstract
MicroRNAs (miRNAs) recently emerged with a key role in multiple myeloma (MM) pathophysiology and are considered important regulators of MM cell growth and survival. Since miRNAs can act either as oncogenes or tumour suppressors, the potential of targeting the miRNA network arises as a novel therapeutic approach for human cancer. Potential strategies based on miRNA therapeutics basically rely on miRNA inhibition or miRNA replacement approaches and take benefit respectively from the use of antagomirs or synthetic miRNAs as well as from lipid-based nanoparticles which allow an efficient miRNA-delivery. The availability of experimental in vivo platforms which recapitulate the growth of MM cells within the specific human bone marrow microenvironment in immunocompromised mice (SCID-hu and SCID-synth-hu) provides powerful systems for development of miRNA-based therapeutics in MM. Preliminary findings on the anti-MM activity of synthetic miRNAs in such experimental models offer a proof-of-principle that miRNA therapeutics is a promising opportunity for this still incurable disease representing the rationale for a new venue of investigation in this specific field.

Abstract
MicroRNAs (miRNAs) with tumor-suppressor potential might have therapeutic applications in multiple myeloma (MM) through the modulation of still undiscovered molecular pathways. Here, we investigated the effects of enforced expression of miR-29b on the apoptotic occurrence in MM and highlighted its role in the context of a new transcriptional loop that is finely tuned by the proteasome inhibitor bortezomib. In details, in vitro growth inhibition and apoptosis of MM cells was induced by either transient expression of synthetic miR-29b or its stable lentivirus-enforced expression. We identified Sp1, a transcription factor endowed with oncogenic activity, as a negative regulator of miR-29b expression in MM cells. Since Sp1 expression and functions are regulated via the 26S proteasome, we investigated the effects of bortezomib on miR-29b-Sp1 loop, showing that miR-29b levels were indeed upregulated by the drug. At the same time, the bortezomib/miR-29b combination produced significant pro-apoptotic effects. We also demonstrated that the PI3K/AKT pathway plays a major role in the regulation of miR-29b-Sp1 loop and induction of apoptosis in MM cells. Finally, MM xenografts constitutively expressing miR-29b showed significant reduction of their tumorigenic potential. Our findings indicate that miR-29b is involved in a regulatory loop amenable of pharmacologic intervention and modulates the anti-MM activity of bortezomib in MM cells.

Abstract
Small nucleolar RNAs (snoRNAs) and small Cajal body-specific RNAs (scaRNAs) are non-coding RNAs involved in the maturation of other RNA molecules and generally located in the introns of host genes. It is now emerging that altered sno/scaRNAs expression may have a pathological role in cancer. This study elucidates the patterns of sno/scaRNAs expression in multiple myeloma (MM) by profiling purified malignant plasma cells from 55 MMs, 8 secondary plasma cell leukemias (sPCLs) and 4 normal controls. Overall, a global sno/scaRNAs downregulation was found in MMs and, even more, in sPCLs compared with normal plasma cells. Whereas SCARNA22 resulted the only sno/scaRNA characterizing the translocation/cyclin D4 (TC4) MM, TC2 group displayed a distinct sno/scaRNA signature overexpressing members of SNORD115 and SNORD116 families located in a region finely regulated by an imprinting center at 15q11, which, however, resulted overall hypomethylated in MMs independently of the SNORD115 and SNORD116 expression levels. Finally, integrative analyses with available gene expression and genome-wide data revealed the occurrence of significant sno/scaRNAs/host genes co-expression and the putative influence of allelic imbalances on specific snoRNAs expression. Our data extend the current view of sno/scaRNAs deregulation in cancer and add novel information to the bio-molecular complexity of plasma cell dyscrasias.

Abstract
Multiple myeloma (MM) is characterized by the impaired osteogenic differentiation of human mesenchymal stromal cells (hMSCs). Canonical Wnt signaling is critical for the regulation of bone formation, however, recent evidence suggests that the non-canonical Wnt agonist Wnt5a stimulates human osteoblastogenesis through its co-receptor Ror2. The effects of MM cells on non-canonical Wnt signaling and the effect of the activation of this pathway on MM-induced osteoblast exhaustion are not known and were investigated in this study. We found that the osteogenic differentiation of bone marrow hMSCs toward osteoprogenitor cells (PreOB) significantly increased Ror2 expression, and that MM cells inhibit Ror2 expression by PreOB in co-culture by inhibiting the non-canonical Wnt5a signaling. The activation of the non-canonical Wnt pathway in hMSCs by means of Wnt5a treatment and the overexpression of Wnt5 or Ror2 by lentiviral vectors increased the osteogenic differentiation of hMSCs and blunted the inhibitory effect of MM in co-culture. Consistently, Wnt5a inhibition by specific small interfering RNA reduced the hMSC expression of osteogenic markers. Our findings demonstrate that the Wnt5a/Ror2 pathway is involved in the pathophysiology of MM-induced bone disease and that the activation of the non-canonical Wnt5a/Ror2 pathway in hMSCs increases osteogenic differentiation and may counterbalance the inhibitory effect of MM cells.

Abstract
In the period 2008-2010, 309 Neisseria meningitidis, isolated in Italy within the National Surveillance of the Invasive Meningococcal Diseases, have been tested for their phenotypic and genotypic characteristics. The main results obtained are: (a) an increase of the strains of serogroup B and a decrease of serogroup C; (b) a phenotypic and genotypic variability of the ST-41/44 clonal complex, the most frequently isolated among serogroup B strains; (c) a decrease of ST-8 clonal complex among serogroup C meningococci whereas strains belonging to ST-11 clonal complex are nowadays the most frequently isolated.

Abstract
The involvement of osteocytes in multiple myeloma (MM)-induced osteoclast (OCL) formation and bone lesions is still unknown. Osteocytes regulate bone remodelling at least partially, as a result of their cell death triggering OCL recruitment. In this study, we found that the number of viable osteocytes was significantly smaller in MM patients than in healthy controls, and negatively correlated with the number of OCLs. Moreover, the MM patients with bone lesions had a significantly smaller number of viable osteocytes than those without, partly because of increased apoptosis. These findings were further confirmed by ultrastructural in vitro analyses of human preosteocyte cells cocultured with MM cells, which showed that MM cells increased preosteocyte death and apoptosis. A micro-array analysis showed that MM cells affect the transcriptional profiles of preosteocytes by upregulating the production of osteoclastogenic cytokines such as interleukin (IL)-11, and increasing their pro-osteoclastogenic properties. Finally, the osteocyte expression of IL-11 was higher in the MM patients with than in those without bone lesions. Our data suggest that MM patients are characterized by a reduced number of viable osteocytes related to the presence of bone lesions, and that this is involved in MM-induced OCL formation.
