Impact of Mycobacterium tuberculosis Infection on Human B Cell Compartment and Antibody Responses

2022

Tuberculosis (TB) remains one of the most important health challenges worldwide. Control of the TB epidemic has not yet been achieved because of the lack of an effective vaccine and rapid and sensitive diagnostic approaches, as well as the emergence of drug-resistant forms of M. tuberculosis. Cellular immunity has a pivotal role against M. tuberculosis infection, but the role of humoral immunity is still controversial. We analyzed the frequency, absolute counts, and phenotypic and functional subsets of B lymphocytes in the peripheral blood of patients with active TB and subjects with latent infection compared to healthy donors. Moreover, we analyzed serum levels of total Ig and their IgA, I…

The Abundance of Tumor-Infiltrating CD8+ Tissue Resident Memory T Lymphocytes Correlates with Patient Survival in Glioblastoma

2022

Glial tumors alone account for 40% of all CNS tumors and present a low survival rate. The tumor microenvironment is a critical regulator of tumor progression and therapeutic effectiveness in glioma. Growing evidence from numerous studies of human solid tumor-infiltrating CD8(+) T cells indicates that tissue-resident memory T cells (TRM) represent a substantial subpopulation of tumor-infiltrating lymphocytes (TILs). Although it is reported that some types of cancer patients with high immune infiltration tend to have better outcomes than patients with low immune infiltration, it seems this does not happen in gliomas. This study aimed to characterize TRMs cells in the glioma tumor microenviron…

Working memory e jumping to conclusions

2017

Differenti studi hanno riscontrato nei pazienti con diagnosi di disturbo psicotico una diffusa compromissione delle funzioni esecutive, in particolare della Working Memory, e una tendenza a prendere decisioni rapidamente dovuta ad errori nel processamento di raccolta delle informazioni presenti nel contesto (Jumping To Conclusion, JTC). Obiettivo del presente studio é quello indagare la presenza di una possibile correlazione tra Working Memory e Jumping To Conclusions in un campione di pazienti al primo episodio psicotico. Per il presente studio sono stati valutati 41 pazienti all’esordio psicotico (58,5% M), di età media 29,63 (DS=10,285) e 89 controlli sani (47,2% M), di età media 33,31 (…

Volatility co-movements: a time scale decomposition analysis

2013

In this paper we investigate short-run co-movements before and after the Lehman Brothers’ collapse among the volatility series of US and a number of European countries. The series under investigation (implied and realized volatility) exhibit long-memory and, in order to avoid missspecification errors related to the parameterization of a long memory multivariate model, we rely on wavelet analysis. More specifically, we retrieve the time series of wavelet coefficients for each volatility series for high frequency scales, using the Maximal Overlapping Discrete Wavelet transform and we apply Maximum Likelihood for a factor decomposition of the short-run covariance matrix. The empirical evidence…

Wavelet Analysis Of Variance Risk Premium Spillovers

2013

In this paper we construct a variance risk premium spillover index among France, Germany, UK, Switzerland and the US. The variance risk premium is measured by the difference between the difference between the (square) of implied volatility and expected realized variance of the stock market for next month. We also construct a spillover index for the constituents of the variance risk premium. The series under investigation exhibit long memory properties. The construction of a total spillover indicator suggested by Diebold-Yilmaz (2009) would then rely on modeling a fractionally integrated Vector Autoregressive Model, which might be subject to errors in specifying the correct lag length and th…

Gender Violence: Social Structure in Latin America, the question of victim and trauma.

2014

In this article, I firstly argue that femicide is a word that indicates the psychological and physical violence against women because they belong to the female gender. I analyze in particular the femicide cases that took place in the border between Ciudad Juarez and Texas from 1993 until now, in addition to the cases on the border between Tijuana and Baja California. During this period more than 700 women were murdered in the border area between Ciudad Juarez and El Paso, still the criminals of these brutal homicides are unknown. The reason for the lack of justice can be explained through institutional corruption and the existence of a patriarchal society. Through an interdisciplinary appro…

“Memorycide” and gender violence in a Society of Eastern Europe

2016

This research proposes to explore the nexus between “denied memory” or “wounded memory” and gender violence normalized in a symbolic level of production of meaning. For this respect, the following points will be analyzed: a) the perception of violence in intimate relationships of second generations post-conflict ; b) the impact of the “memory of war” on “cultural perception of violence” among generations of younger, adults and elder and between women and men of same generation. The central thesis of this essay is that in a post-war Serbian society, the memory is collectively “denied” because of Serbs’ stigmatization, and an increase of violent behavior and a greater incorporation of symboli…

Implementing Immersive Clustering with VR Juggler

2005

Continuous, rapid improvements in commodity hardware have allowed users of immersive visualization to employ high-quality graphics hardware, high-speed processors, and significant amounts of memory for much lower costs than would be possible with high-end, shared memory computers traditionally used for such purposes. Mimicking the features of a single shared memory computer requires that the commodity computers act in concert—namely, as a tightly synchronized cluster. In this paper, we describe the clustering infrastructure of VR Juggler that enables the use of distributed and clustered computers for the display of immersive virtual environments. We discuss each of the potential ways to syn…
