The development of oncolytic viruses (OVs) has increased significantly in the past 20 years, with many candidates entering clinical trials and three of them receiving approval for some indications. Recently, OVs have also gathered interest as candidates to use in combination with immunotherapies for cancer due to their immunogenic properties, which include immunogenic cell death and the possibility to carry therapeutic transgenes in their genomes. OVs transform non-immunogenic ‘cold’ tumors into inflamed immunogenic ‘hot’ tumors, where immunotherapies show the highest efficacy. However, in monotherapy or in combination with immunotherapy, OVs face numerous challenges that limit their successful application, in particular upon systemic administration, such as liver sequestration, neutralizing interactions in blood, physical barriers to infection, and fast clearance by the immune system. In this regard, the use of mesenchymal stem cells (MSCs) as cells carrier for OV delivery addresses many of these obstacles acting as virus carriers and factories, expressing additional transgenes, and modulating the immune system. Here, I review the current progress of OVs-loaded MSCs in cancer, focusing on their interaction with the immune system, and discuss new strategies to improve their therapeutic efficacy.

AbstractThe synthesis of clay minerals has been studied for decades in an attempt to better understand their formation in natural environments and more recently to obtain clay minerals with controlled compositions and properties. Even though nontronite has been synthesized successfully since 1935, the process is not a straightforward and has been poorly documented. In the present review concerning the synthesis of nontronite and other Fe-rich smectites, the experiments attempted in the past are discussed critically in light of the most recent data. Most notably, the application of relationships established recently, thanks to synthetic smectitic series, have allowed us to refine the chemical compositions of some nontronites synthesized previously.

Abstract Globalization, the decline of Western hegemony, and the rise of new political and economic actors, particularly in East Asia, are concomitant with the emergence of more encompassing historical perspectives, attentive to the achievements and historical trajectories of other regions of the world. Global history provides thus a new framework to understanding our past that challenges former views based on the cultural needs, values, and expectations of the West. This means that humanities and social sciences are subject to intense scrutiny and pressed to adapt themselves to a changing cultural, academic, and intellectual environment. However, this process is hindered by the gradual loss of their former prestige and by the increasing influence of economics in the reorganization of the educational, research, and cultural agenda according to market-oriented criteria. The result is that the mobilization of the past increasingly conforms to new strategies in which connectivity, trading, and diplomatic interests, as well as integration in dynamic flows of wealth, appear of paramount importance. Egyptology is not alien to these challenges, which will in all probability reshape its very foundations in the foreseeable future.

Over the past several years, despite the constant evolution of the legislation the problem of gender equality in the West has been steadily increasing. What is the reason why there is no significant progress in solving gender equality issues in the West yet? Several reports and researches have pointed out to this problem. On the contrary, Islam provides a viable solution to this ever increasing problem; for Islam has a comprehensive yet simple view of gender equality. But the West, instead of understanding Islamic principles objectively, raises objections without a thorough study. However, the Western principle of gender equality has completely failed. In this article a critical analysis of the western gender equality and Islamic principles has been carried out. It also highlights Islamic view point of gender equality. The study argues that the contemporary gender equality problems and issues that have engulfed the world particularly the Western countries can be mitigated by employing the Islamic principles of gender equality

Resumen: Este artículo tiene por objeto analizar los principales debates y avances en uno de los campos más punteros y prolíficos de la historiografía a nivel internacional: los estudios de la guerra, también conocidos como nueva historia militar. Para ello propongo un recorrido a través de los cambios que se han producido dentro de éste ámbito durante las dos últimas décadas, así como también un examen crítico de los trabajos y tendencias historiográficas que más han contribuido a ello. En este sentido, planteo una puesta en valor de los estudios de la guerra y destaco su importancia para el conjunto de la historiografía por su capacidad para complejizar nuestro conocimiento y explicaciones del pasado; por el amplio y sugerente abanico de casos de estudio que pone a nuestra disposición; por sus tremendas posibilidades y potencial renovador a nivel metodológico e interpretativo; y, no menos importante, por su tremenda actualidad y sus conexiones con el presente.Palabras clave: estudios de la guerra, nueva historia militar, historia social, estudios de género, estudios culturales, guerra total.Abstract: This article is intended to analyze the major discussions and developments in one of the most prolific and a cutting-edge historiographic field on an international level: the war studies, also known as new military history. For this reason I propose a look through the changes which have taken place in this area over the last two decades, as well as a critical review of the works and historiographical paradigms that have contributed in that way. In this sense I defend the value of war studies and its importance for the whole historiography, taking into account specially its capacity to enable a more complex understanding and explanation of the past; the wide and suggestive range of subject matters that place at our disposal; its huge possibilities and renewing potential on a methodological and interpretative level; and last but not least its great influence and connections with the present.Keywords: war studies, new military history, social history, gender studies, cultural studies, total war.

This chapter identifies some methodological problems of the study of Jewish history in Poland between the two World Wars. The growing public interest in the history of Polish Jews between the wars has been the reason for the publication of many books and articles. Some are based on only a superficial survey, others present a deep and penetrating analysis of specific problems. This body of literature deserves methodological consideration, together with a critical review of the most important sources, so that some queries, doubts and suggestions can be raised. During at least the past hundred years, a tradition developed in some Jewish and Polish political circles of treating the Jews as a kind of alien body within Polish society. This attitude can also often be observed in contemporary historical studies, despite the authors' declared intentions. This can partly be explained in terms of the distant past, when Jews constituted a distinctly different class of people with its own legal status and institutions, but there is no reason to maintain such an approach when investigating the history of the 20th century.
