Abstract
Mercury's southern inner magnetosphere is an unexplored region as it was not observed by earlier space missions. In October 2021, BepiColombo mission has passed through this region during its first Mercury flyby. Here, we describe the observations of SERENA ion sensors nearby and inside Mercury's magnetosphere. An intermittent high-energy signal, possibly due to an interplanetary magnetic flux rope, has been observed downstream Mercury, together with low energy solar wind. Low energy ions, possibly due to satellite outgassing, were detected outside the magnetosphere. The dayside magnetopause and bow-shock crossing were much closer to the planet than expected, signature of a highly eroded magnetosphere. Different ion populations have been observed inside the magnetosphere, like low latitude boundary layer at magnetopause inbound and partial ring current at dawn close to the planet. These observations are important for understanding the weak magnetosphere behavior so close to the Sun, revealing details never reached before.

Abstract
We report an experimental study on the effect of Mn impurities in the optimally doped [Formula: see text] compound. The results show that a very tiny amount of Mn, of the order of 0.1%, is enough to destroy superconductivity and to recover at low temperatures both the magnetic ground state and the orthorhombic structure of the pristine LaFeAsO parent compound. The results are discussed within a model where electron correlations enhance the Ruderman-Kittel-Kasuya-Yosida interaction among impurities.

Abstract
The need for in vitro models that mimic the human brain to replace animal testing and allow high-throughput screening has driven scientists to develop new tools that reproduce tissue-like features on a chip. Three-dimensional (3D) in vitro cultures are emerging as an unmatched platform that preserves the complexity of cell-to-cell connections within a tissue, improves cell survival, and boosts neuronal differentiation. In this context, new and flexible imaging approaches are required to monitor the functional states of 3D networks. Herein, we propose an experimental model based on 3D neuronal networks in an alginate hydrogel, a tunable wide-volume imaging approach, and an efficient denoising algorithm to resolve, down to single cell resolution, the 3D activity of hundreds of neurons expressing the calcium sensor GCaMP6s. Furthermore, we implemented a 3D co-culture system mimicking the contiguous interfaces of distinct brain tissues such as the cortical-hippocampal interface. The analysis of the network activity of single and layered neuronal co-cultures revealed cell-type-specific activities and an organization of neuronal subpopulations that changed in the two culture configurations. Overall, our experimental platform represents a simple, powerful and cost-effective platform for developing and monitoring living 3D layered brain tissue on chip structures with high resolution and high throughput.

Abstract
^{75}As, ^{87}Rb, and ^{85}Rb nuclear quadrupole resonance (NQR) and ^{87}Rb nuclear magnetic resonance measurements in a RbFe_{2}As_{2} iron-based superconductor are presented. We observe a marked broadening of the ^{75}As NQR spectrum below T_{0}≃140 K which is associated with the onset of a charge order in the FeAs planes. Below T_{0} we observe a power-law decrease in the ^{75}As nuclear spin-lattice relaxation rate down to T^{*}≃20 K. Below T^{*} the nuclei start to probe different dynamics owing to the different local electronic configurations induced by the charge order. A fraction of the nuclei probes spin dynamics associated with electrons approaching a localization while another fraction probes activated dynamics possibly associated with a pseudogap. These different trends are discussed in light of an orbital selective behavior expected for the electronic correlations.

Abstract
Amifostine (WR-2721, Ethyol(TM)) is a chemo-and radioprotective agent which is increasingly used in clinical practice to minimize antitumor therapy-induced toxicities. The key of this property of amifostine is certainly its selective action in terms of differential protection of normal tissue and not of tumor cells. Using HUVEC cells and three different cancer cell lines (A549 non-small cell lung cancer, DND-1A melanoma and HeLa cervical carcinoma) we provide evidence that amifostine could protect normal, and not cancer cells, from cisplatin (CDDP)-induced cytotoxicity in vitro. Furthermore, low doses of amifostine, easily attainable in vivo, can protect 50% of normal cells in vitro from CDDP-induced cytotoxicity.

Abstract
The fast inhibitory neurotransmitters glycine and GABA are co-localized in synaptic terminals of inhibitory interneurons in the spinal cord and co-released onto lumbar motoneurons in neonatal rats. We performed whole-cell voltage-clamp experiments on spinal cord preparations obtained from juvenile (P8–14) mice to determine whether inhibitory currents exhibited GABAergic components in motoneurons of animals of weight-bearing age. Subsequently we established whether or not GABA is co-released at glycinergic synapses onto motoneurons by determining if it conferred modulatory effects on the kinetics of glycinergic currents. Exponential fitting analysis showed that evoked and miniature inhibitory post-synaptic currents (IPSCs) were best-fitted with a single decay time constant. Responses recorded from connected interneuron-motoneuron pairs showed no effect of a benzodiazepine or a GABAA receptor antagonist. Similarly IPSCs evoked by extracellular stimulation and miniature IPSCs were not affected by either agent, indicating the absence of co-detection. Experimental manipulation of the relative content of pre-synaptic GABA and glycine conferred no effect on post-synaptic responses. It is thus unlikely that GABA is co-released in biologically relevant amounts at glycinergic synapses onto lumbar motoneurons in mice of this age.

Abstract
Neonatal pulmonary hypertension refractory to high frequency ventilation (HFOV) and inhaled nitric oxide (iNO) is an occasional occurrence. We report a full-term neonate with severe pulmonary hypertension unresponsive to the treatment with HFOV and iNO, later associated with prostacyclin, who rapidly improved after the addition of vecuronium, a neuromuscular blocker.

Abstract
ABSTRACTOur approach consists of improving the molecular architecture of π-electron delocalization and orientations of the polymeric backbone of materials for cubic nonlinear optics. First, the syntheses of new polymers such as substituted polyacetylenes or polyphenyleneynylenes were done, in which the stiff conjugated chain and the flexible side-chains are well adapted to the orientation of the backbone. They have been studied for their third order susceptibility and their ability to give processable optical films. We have found liquid crystal properties with the rigid rod derivative of the poly(ethynylarylene). Unlike previous poly(ethynylarylene), we obtained a high molecular weight: , which allows films of good optical and mechanical properties. Second, in order to increase the third order response, we focused our attention on the orientational order of polydiacetylenes, which we obtained by epitaxial growth of the monomer on a single crystal substrate. From the proposed epitaxial model a possible extension of highly oriented thin films can be applied to a large class of materials.

Abstract
416 Background: Advances in understanding the mechanisms underlying diseases and drug responses are creating increasing opportunities to offer safer and more effective treatments to individual patients (pts). Biomarkers are needed for predicting likelihood of therapeutic safety and efficacy in each individual pt. Down-regulation of core clock gene PER2 in tumors predicted for poor survival in pts with metastatic colorectal cancer (Jacobelli. J Clin Oncol. 26: 2008 May 20 suppl; abstr 11032). Methods: A clinical data base and tissue bank involving primary tumor (T) and healthy adjacent colon mucosa (C) from 139 pts treated with circadian-shaped or standard infusion of (A)-single-agent irinotecan (63 pts) or (B) in combination with oxaliplatin and 5FU (76 pts) for previously-treated metastatic colorectal cancer was established and tissues were collected. Clinical relevance of constitutive or acquired single nucleotide polymorphisms (SNPs) for 5 metabolism (ABCB1, ABCB2, CES2, TOP1, UGT1A1) and for two PER2 SNP's (A4572G and C3968T). Results: No acquired mutation in the genes analysed was found (100% T and C concordance). The incidence of grade 3-4 toxic event of any kind was significantly lower in women as compared to men in A population(39% vs 76%, p=0.007) and in A+B population (p=0.05), independently from other factors (p=0.02) this difference is lost if you consider only B population where oxaliplatin is added (p=0.5). No SNP in metabolism genes predicted for toxicity in this cohort. Conversely, SNPs in core clock gene PER2 (1 pt with A4572G and 4 pts C3968T) were significantly associated with higher incidence of G3-4 toxicity (100% in polymorphic pts. vs 17.2% in wild type pts, p=0.01). Conclusions: Irinotecan tolerability is sex dependent and woman has significative low incidence of toxic effects. We demonstrated for the first time an association between constitutive SNPs in a core clock gene and toxicity, further supporting the relevance of the circadian timing system in chemotherapy tolerability. Moreover, our findings are in good agreement with data in mice, supporting the hypothesis that sex determines two chronotoxicity classes in patients with metastatic colorectal cancer. No significant financial relationships to disclose.

Abstract
BACKGROUND AND PURPOSE alpha4 and beta2 nicotinic acetylcholine (ACh) receptor subunits expressed heterologously in Xenopus oocytes assemble into a mixed population of (alpha4)(2)(beta2)(3) and (alpha4)(3)(beta2)(2) receptors. In order to express these receptors separately in heterologous systems, we have engineered pentameric concatenated (alpha4)(2)(beta2)(3) and (alpha4)(3)(beta2)(2) receptors. EXPERIMENTAL APPROACH alpha4 and beta2 subunits were concatenated by synthetic linkers into pentameric constructs to produce either (alpha4)(2)(beta2)(3) or (alpha4)(3)(beta2)(2) receptors. Using two-electrode voltage-clamp techniques, we examined the ability of the concatenated constructs to produce functional expression in Xenopus oocytes. Functional constructs were further characterized in respect to agonists, competitive antagonists, Ca2+ permeability, sensitivity to modulation by Zn2+ and sensitivity to up-regulation by chaperone protein 14-3-3. KEY RESULTS We found that pentameric concatamers with a subunit arrangement of beta2_alpha4_beta2_alpha4_beta2 or beta2_alpha4_beta2_alpha4_alpha4 were stable and functional in Xenopus oocytes. By comparison, when alpha4 and beta2 were concatenated with a subunit order of beta2_beta2_alpha4_beta2_alpha4 or beta2_alpha4_alpha4_beta2_alpha4, functional expression in Xenopus oocytes was very low, even though the proteins were synthesized and stable. Both beta2_alpha4_beta2_alpha4_beta2 and beta2_alpha4_beta2_alpha4_alpha4 concatamers recapitulated the ACh concentration response curve, the sensitivity to Zn2+ modulation, Ca2+ permeability and the sensitivity to up-regulation by chaperone protein 14-3-3 of the corresponding non-linked (alpha4)(2)(beta2)(3) and (alpha4)(3)(beta2)(2) receptors respectively. Using these concatamers, we found that most alpha4beta2-preferring compounds studied, including A85380, 5I-A85380, cytisine, epibatidine, TC2559 and dihydro-beta-erythroidine, demonstrate stoichiometry-specific potencies and efficacies. CONCLUSIONS AND IMPLICATIONS We concluded that the alpha4beta2 nicotinic ACh receptors produced with beta2_alpha4_beta2_alpha4_beta2 or beta2_alpha4_beta2_alpha4_alpha4 pentameric constructs are valid models of non-linked (alpha4)(2)(beta2)(3) and (alpha4)(3)(beta2)(2) receptors respectively.

Abstract
In human Burkitt's Lymphoma (BL) BRG cells, a t(8;14) translocation, placing c-myc near the Emu enhancer of the H chain locus, causes tumor expansion. Earlier, we showed that a peptide nucleic acid complementary to the Emu sequence (PNAEmu), specifically inhibited the expression of translocated c-myc and impaired the growth of BRG cells-induced subcutaneous tumors in mice suffering from severe combined immunodeficiency (SCID). In this study, the therapeutic potential of PNAEmu was evaluated in a systemic mouse model. BRG-BL cells transfected with the luciferase gene were inoculated intravenously into SCID mice resulting in a preferential expansion, similar to the one of human adult patients, in the abdominal cavity, central nervous system and bone marrow. The mice were chronically injected intraperitoneally either with PNAEmu or with control PNA. The treatment was stopped when the control animals developed severe neurological symptoms. As detected both by inspection at necropsy and imaging, overall tumor growth in PNAEmu-treated mice decreased by >80%. Histological and immunohistochemical studies showed, only in PNAEmu-treated mice, a substantially reduced BL cell growth at the major sites of invasion and vast areas of necrosis in the lymphomatous tissues, with concomitant c-myc expression downregulation. Altogether, the data support the therapeutic potential of PNAEmu in human adult BL.

Abstract
Lymphangioma is a rare benign tumor caused by failure in the development of the lymphatic communicating system. The corresponding nomenclature is confusing. In recent years ''renal lymphangiectasia'' is the preferred name. Although this disease may occur in any site of the body, the neck (75%) and axillary area (20%) are the most common sites, and the kidney is occasionally involved. We report a case of lymphangioma communicating with the urinary system in a 61-year-old man diagnosed by CT scan treated with nephrectomy and histological confirmation.

Abstract
In the past decade the median overall survival of patients with metastatic colorectal cancer has increased from 12 to more than 20 months, mostly due to the new chemotherapeutic agents, irinotecan and oxaliplatin. Most recently, targeted therapies, that inhibit specific cancer pathways and molecules, have shown promising results in the treatment of patients with metastatic colorectal cancer and other solid tumors. One of the most studied targets for anticancer therapy is the epidermal growth factor receptor (EGFR), which is overexpressed in a variety of malignancies. Cetuximab, an anti-EGFR chimeric monoclonal antibody, has shown clinically meaningful antitumor activity in patients with metastatic colorectal cancer in several clinical trials. Efforts of physicians and researchers are currently directed towards the identification of predictive factors (clinical or molecular) of clinical outcome, with the aim of both optimizing the therapeutic index and dealing with increasing costs of these new compounds.

Abstract
The present document contains recommendations for assessment, prevention and treatment of cardiovascular risk for HIV-infected patients. All recommendations were graded according to the strength and quality of the evidence and were voted on by 73 members of the Italian Cardiovascular Risk Guidelines Working Group which includes both experts in HIV/AIDS care and in cardiovascular and metabolic medicine. Since antiretroviral drug exposure represents only one risk factor, continued emphasis on an integrated management is given. This should include prevention and treatment of known cardiovascular risk factors (such as dyslipidaemia, diabetes, insulin resistance, healthy diet, physical activity, avoidance of smoking), but also rational switch of antiretroviral drugs. A rational switch strategy should consider both metabolic and anthropometric disturbances and effectiveness of antiretroviral regimens.

Abstract
In Burkitt's lymphoma (BL) cells due to a t(8;14) chromosomal translocation c-myc is often placed in proximity to the Emu enhancer of the Ig locus and upregulated. We demonstrated that in BL cells a peptide nucleic acid (PNA), complementary to intronic Emu sequences (PNAEmuwt), specifically blocks the expression of the c-myc oncogene under the Emu enhancer control and inhibits BL cell growth in culture. Here, we investigated whether PNAEmuwt was also able to block tumor growth in SCID mice inoculated with human BL cell lines. After subcutaneous inoculum in mice BL cells reproducibly form tumors. Both pre-treatment of BL cells with PNAEmuwt before inoculum and chronic intravenous administration of PNAEmuwt to mice already inoculated with BL cells selectively caused increased latency of tumor appearance and decreased final tumor size. Tumors from PNAEmuwt-treated animals showed substantial areas of cell necrosis and of c-myc downregulation. Inhibition of tumor growth was specific and was not observed with PNAEmumut carrying sequence mutations and in BL cell lines where the translocated c-myc is not under the control of the Emu enhancer. These data confirm the potential therapeutic value of PNA targeted to regulatory non-coding regions.

Abstract
10770 Background: Heat shock protein, ORP150, plays a role in hypoxia/ischemia and angiogenesis. Preliminary studies demonstrate increased ORP 150 expression in human cancer, and associate its over expression with aggressive tumor biology. This study further evaluates ORP150 expression in different stages of breast cancer, such as benign, pre-malignant and malignant breast lesions and correlates it with clinical-pathological data. Methods: Sixty-six prospectively collected paraffin-embedded breast tissue sections were reviewed for diagnostic confirmation (normal, n=25; DCIS, n=20; invasive breast cancer (Ca), n=21) and stained using ORP150 antibody immunohistochemistry (IHC). Antibody-staining levels in the benign, DCIS and invasive component of each lesion were reviewed independently by two pathologists and scored: 0 (lowest) to 3+ (highest). Clinical-pathological data was compared with ORP150 staining using ANOVA or T-Test as appropriate with significance determined by p<0.05. Results: Significant differential ORP150 staining was detected in benign-normal versus benign adjacent to invasive cancer, as well as in benign adjacent to DCIS versus benign adjacent to invasive cancer. ORP150 expression in the invasive portion of the breast cancer correlated significantly with tumor grade and absence of hormone receptor expression, presence of lymphovascular invasion and lymph node metastasis. Conclusions: ORP150 expression in breast cancer is associated with poor prognostic histological factors. As ORP150 is differentially expressed in benign tissue adjacent to invasive cancer, further study is warranted to determine its utility in detecting occult invasive cancer within benign biopsy specimens, as well as its putative role in tumor-stromal cell interactions.

Abstract
A panel of leading Italian specialists in infectious diseases, virologists and immunologists met in Rome in 2005 to review critical data and discuss recommendations for each of the key questions in antiretroviral therapy today: When to start treatment? How to start? When to switch? What to switch to? Whether to stop or not to stop treatment, and how? The method of a nominal group meeting was used and recommendations were graded for their strength and quality using a system based on the one adopted by the Infectious Diseases Society of America. Main conclusions are summarized and critically discussed in this consensus statement, as well as some of the most recent data supporting these recommendations are provided.

Abstract
Human mammaglobin (hMAM) has recently been recognized as a breast associated glycoprotein. Although the biological role of hMAM is unknown, it has been previously reported that hMAM gene expression is a marker of low biological and clinical aggressiveness of breast cancer (BC). In this study, 148 cases of BC tissues were investigated for hMAM mRNA expression by reverse transcriptase-polymerase chain reaction (RT-PCR). In order to evaluate its prognostic value, hMAM was correlated with age of patients, type and size of tumor, nodal stage, histologic grade, c-erbB-2 over expression, Ki67 labelling index, estrogen receptor (ER) status and progesterone receptor (PGR) status. Fisher's exact test was used to examine the association between different parameters and hMAM. hMAM was expressed in 138/148 (93%) of BC tissues examined. Among the 10 hMAM negative cases, 8 were invasive ductal carcinomas (microscopically higher G3 grade) and 2 infiltrating lobular carcinomas. We found a significant association (p = 0.020) between absence of hMAM mRNA and G3 histologic grade but not with any other prognostic parameters studied. The present study indicates that lack of hMAM expression is restricted to the BC with G3 grading. Further studies are needed to clarify the biological basis and the clinical significance of our results.

Abstract
A method to determine simultaneously the rates of 222Rn and 220Rn released from building materials quarried in Central Italy is presented. The method makes use of a continuous monitor equipped with a solid state alpha detector, in-line connected to a small accumulation chamber. The effects of chamber leakage and back diffusion on 222Rn free exhalation rate is evaluated. The influence of available exhalation surface, humidity content and precursors concentration on radon and thoron exhalation rates is investigated.

Abstract
Hepatitis C virus (HCV) variability is mainly attributed to the ability of the virus to respond to host immune pressure, acting as a driving force for the evolution of quasispecies. This study was aimed at studying the changes in HVR-1 heterogeneity and the evolution of HCV quasispecies in HIV/HCV-coinfected patients according to the pattern of response to highly active antiretroviral therapy (HAART). Sixteen HIV/HCV-coinfected patients harbouring HCV genotype 1 and who had been on HAART for at least 1 year, 8 showing increasing CD4+T-cell counts (immunological responders) and 8 showing a stable or decreasing CD4+ T-cell counts (immunological non-responders), were selected from a prospective cohort study. After 1 year of HAART, 11 patients showed HIV viral load <2.6 log10 cp/ml (virological responders), and 5 showed HIV viral load above this value (virological non-responders). Plasma samples, collected before starting therapy and after 1 year of HAART, underwent clonal sequence analysis for HVR-1 region of HCV. Non-synonymous/synonymous substitutions ratio (Ka/Ks), aminoacidic complexity (normalized Shannon entropy) and diversity (p-distance), were considered as parameters of quasispecies heterogeneity. After 1 year of HAART, heterogeneity of HVR-1 quasispecies significantly decreased in virological non-responders, whereas the heterogeneity tended to increase in virological responders. The differences in the evolution were less stringent, when considering immunological response. On the other hand, profound qualitative modifications of HVR-1 quasispecies were observed only in patients with both immunological and virological HAART response. On the whole, these findings suggest that, in patients undergoing HAART, the extent of HCV variability and the evolution of HVR-1 quasispecies is influenced by the pattern of response to antiretroviral therapy.

Abstract
Depleted uranium (DU), a waste product of uranium enrichment, has several civilian and military applications. It was used as armor-piercing ammunition in international conflicts and was claimed to contribute to health problems, known as the Gulf War Syndrome and recently as the Balkan Syndrome. Leukaemia/Limphoma cases among UN soldiers in the Balkans have been related hypothetically to exposure to DU. The investigations published in the scientific literature give no support for this hypothesis. However future follow-up is necessary for evaluation of long-term risk.

Abstract
Ureteral hernia is uncommon and usually misdiagnosed. From an anatomic point of view, we can distinguish between two uretero-inguinal hernias: intraperitoneal and extraperitoneal. Ureter inguinal hernias are nearly always indirect. This kind of hernia can include the ureter alone or, frequently, other abdominal sliding organs within the hernia sac (bladder, bowel tracts, etc.). Kidneys and urinary tracts present normal anatomic conformation, although renal ptosis may be found. As of July 2004, 139 cases of ureteral hernia had been described in the literature. Here we report a case of inguino-scrotal herniation of double district ureter and review the current literature to analyze the main clinical characteristics of this pathology and to establish pitfalls.

Abstract
Background Chronic hepatitis C is common and aggressive in HIV-positive patients, so the development of a well-tolerated HCV therapy is a priority. We evaluated the efficacy and safety of pegylated interferon α2b (PEG-IFN) plus ribavirin (RBV) versus PEG-IFN monotherapy in HIV/HCV-coinfected patients undergoing highly active antiretroviral therapy (HAART), and analysed the predictive factors of response. Methods An Italian, multicentre, open-label trial including 135 coinfected patients, randomized to PEG-IFN 1.5 μg/kg/week plus RBV 400 mg twice daily ( n=69, arm A) or PEG-IFN 1.5 μg/kg/week ( n=66, arm B) for 48 weeks. We assessed the predictive values of early virological response (EVR) at week 8 (HCV-RNA drop >2 log10 compared with baseline or undetectable levels) on sustained virological response (SVR). Results Fifty-five patients (28 from arm A and 27 from arm B) completed 48 weeks of therapy. At the end of treatment, 20/28 patients in arm A and 11/27 in arm B had HCV-RNA <50 IU/ml. In a per-protocol analysis, SVR was reached by 54% of patients in arm A (genotype 2–3, 11/16; genotype 1–4, 4/12) and 22% in arm B (genotype 2–3, 3/15; genotype 1–4, 3/12). In an intention-to-treat analysis, the SVR was 22% in arm A (genotype 2–3, 11/32; genotype 1–4, 4/37) versus 9% in arm B (genotype 2–3, 3/32; genotype 1–4, 3/34). The best predictors of SVR were the use of combination therapy, infection with HCV genotype 3 versus genotype 1, and EVR at week 8. Thirty patients (15 from arm A and 15 from arm B) dropped out of the trial prematurely due to side effects. The positive predictive value of EVR at week 8 was 65%, the negative predictive value was 86%. Conclusions PEG-IFN plus RBV can be considered a solid option for the treatment of HIV/HCV-coinfected patients. The key to successfully improving efficacy is strong compliance through strict overall patient monitoring, in order to best manage drug toxicity. EVR assessment at week 8 may become a useful stategy in the management of therapy.

Abstract
The prognostic role of GB virus type C (GBV-C) viraemia in HIV-infected subjects treated with highly active antiretroviral therapy (HAART) is still undefined, The aim of this analysis is to assess the relationship between GBV-C infection and response to antiretroviral therapy among HIV-infected subjects initiating HAART when antiretroviral-naive. A prospective, observational study of 400 HIV-infected patients with measurements of GBV-C RNA, hepatitis C virus (HCV) antibodies and HCV RNA determined from plasma stored prior to HAART initiation, Time to virological (achieving HIV RNA ≤500 copies/ml) and immunological success (a CD4+ count increase of ≥200cells/μl), and the time to virological relapse (confirmed HIV RNA >500 copies/ml) were assessed by Kaplan-Meier methods and Cox proportional hazard regression model. Of the subjects, 117 (29.3%) were GBV-C positive and, overall, 351 (87.8%) patients achieved virological success, After controlling for a number of confounders including HCV RNA, GBV-C viraemic patients experienced a significantly lower risk of HIV rebound than those who were GBV-C negative [relative hazard (RH)=0.56, 95% CI: 0.34–0.93, P=0.03], Conversely, the probability of achieving initial virological success or CD4+ count response after HAART did not differ between GBV-C-negative and -positive subjects, These results suggest that GBV-C coinfection may play a role in determining the rate of HIV rebound possibly by competing with HIV replication after HIV load has been successfully suppressed by HAART.

Abstract
High level HIV-1 drug resistance in recently infected treatment-naive individuals correlates with sub-optimal virological responses to highly active antiretroviral therapy (HAART). To determine whether genotypic HIV-1 drug resistance in chronic naive patients, as interpreted by various systems, could predict the virological outcomes of HAART, isolates from patients enrolled in a prospective observational cohort (ICoNA) prior to treatment start were genotyped. Genotypic susceptibility scores (GSS) assigned to the initial HAART regimens using the interpretations of pre-therapy resistance mutations by 13 systems were related to virological outcomes. Of 415 patients, 42 (10%) had at least one major resistance mutation. According to the different interpretations, 1.9–20.5% of patients had some level of resistance to at least one drug in the initial regimen. In multivariable analysis, GSS from two systems significantly predicted the time to virological success: Rega 5.5, for each unit increase in GSS adjusted relative hazard (RH) 1.86 [95% confidence intervals (95% CI): 1.15–3.02] and hivresistanceWeb v3, RH 1.87 (95% CI: 1.00–3.48). With three other systems, GSS showed a trend towards a significant prediction of success: Retrogram 1.6, RH 2.33 (95% CI: 0.98–5.53), Menéndez 2002, RH 2.36 (95% CI: 0.97–5.72) and Stanford hivdb, RH 2.06 (95% CI: 0.94–4.49). Genotypic resistance testing coupled with adequate interpretation in chronic naive patients can usefully identify those at risk of sub-optimal virological response to HAART.

Abstract
We examined the impact of a lamivudine-containing highly active antiretroviral therapy (HAART) regimen on 164 hepatitis B virus/HIV co-infected individuals starting their first HAART. Lamivudine-treated patients (accounting for 73% of the study population) showed a significantly lower level of alanine aminotransferase over follow-up [–81.1 mU/ml mean difference; 95% confidence intervals (95% CI): –30.3; –131.7, P=0.003] and a significantly reduced risk of liver-related morbidity/mortality [Relative hazard (RH)=0.07; 95% CI: 0.01–0.38, P=0.002] than those starting a lamivudine sparing-regimen.

Abstract
We studied the predictive value of self-reported adherence and plasma drug concentrations on virological rebound to HAART. Among 238 participants in the AdICoNA study who had viral load ≤500 copies/ml, 42 (17.6%) experienced virological rebound by 96 weeks. Both self-reported non-adherence and sub-optimal concentration were independently associated with a higher risk of virological rebound.

Abstract
Forty patients participating in the TRIZAL study were treated with a non-nucleoside reverse transcriptase inhibitor (NNRTI)-containing regimen before being randomly assigned either to continue their baseline therapy or to switch to a triple nucleoside regimen. No difference was observed in treatment efficacy between the two groups, and total cholesterol was observed to improve significantly in the switch group. Switch maintenance may be an appropriate strategy in patients treated with an NNRTI.

Abstract
In this report, we describe a case of poorly differentiate myoepithelial cell rich carcinoma in with morphological findings of large poligonal nests with festoon-like pattern sometimes showing central necrosis, reminiscent of a comedo-like pattern and numerous mitoses. Immunohistochemical staining shows positive reaction for cytokeratin AE/1, CAM 5.2, 34 beta E12, vimentin, smooth muscle actin, EMA, S100 protein and oncogene cERB.b2 and negative for estrogen, progesterone, GFAP and chromogranin. Moreover, this carcinoma show the expression of the mammaglobin mRNA, a highly specific marker of breast epithelial cells that it is not expressed in all breast carcinoma.

Abstract
We evaluated the toxicity and activity of bleomycin, methotrexate and vinorelbine (BMV) combination chemotherapy in cisplatin-pretreated patients with squamous cell carcinoma of the head, neck and esophagus (SCC-HN&E) with the aim of identifying a second-line therapy combination and schedule that might offer an improved therapeutic index. BMV (bleomycin 15 I.U., total dose, methotrexate 30 mg/m2, and vinorelbine 30 mg/m2) was administered intravenously every 2 weeks until disease progression, to 26 consecutive patients. Clinical and CT-scan evaluations revealed 7 partial responses (PR) 127%, 95% confidence interval: 9.6%-44.4%], and 13 patients with stable disease (SD) [50%]. The mean progression-free survival for patients who achieved a PR or SD was 6.47 months (range 4-13 months), with 75% of these patients experiencing partial relief of symptoms, mainly pain and dysphagia. BMV, administered second-line in an outpatient setting, has activity similar to that of the taxanes, but with a more acceptable toxicity profile including an absence of alopecia.

Abstract
To correlate cerebral histopathological and immunohistochemical changes in the neuroclinical features of the AIDS dementia complex (ADC), autopsy results of 28 ADC patients were related, in a retrospective analysis, to scores on a standardised neurological examination performed at neurologic onset. From a histopathological point of view, the cases were classified as follows: 9 cases of HIV leucoencephalopathy (HIVL; diffuse myelin damage and rare microglial nodules), 7 cases of HIV encephalitis (HIVE; several microglial nodules and no myelin damage) and 12 cases of mixed HIVL and HIVE (HIVL-E). The groups differed significantly with respect to symptoms and CD4 count at neurologic onset, survival and neurological impairment. Immunohistochemically, the interstitial component (p24-positive cells scattered singly within the white matter) was significantly more prevalent in HIVL, and the micronodular component (p24-positive cells confined within microglial nodules) in HIVE. Neurological damage was worse in cases with a high prevalence of interstitial component or a low prevalence of micronodular component. HIVE, HIVL and HIVL-E are distinct clinical forms of ADC. Neurological impairment is related to white matter damage.
