Pancreatic cancer(PDAC) is an aggressive and chemoresistant disease, representing the fourth cause of cancer related deaths in western countries. Majority of patients have unresectable, locally advanced or metastatic disease at time of diagnosis and the 5-year survival rate in these conditions is extremely low. For more than a decade gemcitabine has been the cornerstone of metastatic PDAC treatment, although survival benefit was very poor. PDAC cells are surrounded by an intense desmoplastic reaction that may create a barrier to the drugs penetration within the tumor. Recently PDAC stroma has been addressed as a potential therapeutic target. Nano albumin bound(Nab)-paclitaxel is an innovative molecule depleting tumor stroma, through interaction between albumin and secreted protein acidic and rich in cysteine. Addition of nab-paclitaxel to gemcitabine has showed activity and efficacy in metastatic PDAC first-line treatment improving survival and overall response rate vs gemcitabine alone in the MPACT phase Ⅲ study. This combination represents one of the standards of care in advanced PDAC therapy and is suitable to a broader spectrum of patients compared to other schedules. Nab-paclitaxel is under investigation as a backbone of chemotherapy in novel combinations with target agents or immunotherapy in locally advanced or metastatic PDAC. In this article, we provide an updated and critical overview about the role of nab-paclitaxel in PDAC treatment based on the latest advances in preclinical and clinical research. Furthermore, we focus on the use of nab-paclitaxel within the context of metastatic PDAC treatment landscape and we discuss about future implications in the light of current clinical ongoing trials.

HIV integration occurs in chromatin sites that favor the release of high levels of viral progeny;alternatively, the virus is alsoable to discreetly coexist with the host. The viral infection perturbs the cellular environment inducing the remodelling of thenuclear landscape. Indeed, HIV-1 triggers the nuclear clustering of the host factor CPSF6, but the underlying mechanism ispoorly understood. Our data indicate that HIV usurps a recently discovered biological phenomenon, called liquid–liquid phaseseparation, to hĳack the host cell. We observed CPSF6 clusters as part of HIV-induced membraneless organelles (HIV-1 MLOs) inmacrophages, one of the main HIV target cell types. We describe that HIV-1 MLOs follow phase-separation rules and representfunctional biomolecular condensates. We highlight HIV-1 MLOs as hubs of nuclear reverse transcription, while the double-strandedviral DNA, once formed, rapidly migrates outside these structures. Transcription-competent proviruses localize outside but nearHIV-1 MLOs in LEDGF-abundant regions, known to be active chromatin sites. Therefore, HIV-1 MLOs orchestrate viral events priorto the integration step and create a favorable environment for the viral replication. This study uncovers single functional host–viralcomplexes in their nuclear landscape, which is markedly restructured by HIV-1.

Binary asymmetric nanocrystals （BNCs）, composed of a photoactive TiO2 nanorod joined with a superparamagnetic γ-Fe203 spherical domain, were embedded in polyethylene glycol modified phospholipid micelle and successfully bioconjugated to a suitably designed peptide containing an RGD motif. BNCs represent a relevant multifunctional nanomaterial, owing to the coexistence of two distinct domains in one particle, characterized by high photoactivity and magnetic properties, that is particularly suited for use as a phototherapy and hyperthermia agent as well as a magnetic probe in biological imaging. We selected the RGD motif in order to target integrin expressed on activated endothelial cells and several types of cancer cells. The prepared RGD-peptide/BNC conjugates, comprehensively monitored by using complementary optical and structural techniques, demon- strated a high stability and uniform dispersibility in biological media. The cytotoxicity of the RGD-peptide/BNC conjugates was studied in vitro. The cellular uptake of RGD-peptide conjugates in the cells, assessed by means of two distinct approaches, namely confocal microscopy analysis and emission spectroscopy determination in cell lysates, displayed selectivity of the RGD-peptide-BNC conjugate for the cw]33 integrin. These RGD-peptide-BNC conjugates have a high potential for theranostic treatment of cancer.

TORCH complex, one of the potential infections that may occur during pregnancy, may contribute also to prenatal pregnant women’s anxiety and depression. The aim of this study was to explore the presence of psychiatric symptoms, in relation with infection of TORCH agents, specifically the Toxoplasma gondii (T. gondii) and Cytomegalovirus (CMV). The study was conducted on 58 pregnant women recruited from the Clinical Virology Unit, A.O.U. Policlinico-Vittorio Emanuele, P.O. “Gaspare Rodolico”, from September 2012 to March 2014. Psychiatric symptoms were evaluated through the Symptom Checklist-90 Revised (SCL-90 R) in pregnant women with CMV or T. gondii infection. Moreover, pregnant women were invited to participate in a program of “Counseling about behavioral change”, an effective psychotherapeutic training for the development of new motivational strategies to the infection acceptance, the greater self-confidence and greater adherence to treatment. The age of the subjects was positively correlated with Depression (r = 0.119, p ? 0.178, p ? 0.231, r = ? 0.320, p ? 0.208, p ? 0.105, p ? 0.236, p < 0.05). Finally, we can notice an improvement of the variables Anxiety and Somatization in the whole sample after the attendance at the counseling psychotherapic program. Our study suggests the presence of anxiety and somatization in pregnant women with infection, expression of a phase of emotional fragility with the concern of transmitting a serious disease in the unborn child. The program “Counseling about behavioral change” allowed us to create an atmosphere of trust and to understand the usefulness of “empathic listening”. Giving correct and accurate information about the disease reassures the patient and prevents the realization of negative thoughts and further concern and discomfort.
