Can islam be french?
Can Islam Be French? is an anthropological examination of how Muslims are responding to the conditions of life in France. Following up on his book Why the French Don't Like Headscarves, John Bowen turns his attention away from the perspectives of French non-Muslims to focus on those of the country's Muslims themselves. Bowen asks not the usual question--how well are Muslims integrating in France?--but, rather, how do French Muslims think about Islam? In particular, Bowen examines how French Muslims are fashioning new Islamic institutions and developing new ways of reasoning and teaching. He looks at some of the quite distinct ways in which mosques have connected with broader social and political forces, how Islamic educational entrepreneurs have fashioned niches for new forms of schooling, and how major Islamic public actors have set out a specifically French approach to religious norms. All of these efforts have provoked sharp responses in France and from overseas centers of Islamic scholarship, so Bowen also looks closely at debates over how--and how far--Muslims should adapt their religious traditions to these new social conditions. He argues that the particular ways in which Muslims have settled in France, and in which France governs religions, have created incentives for Muslims to develop new, pragmatic ways of thinking about religious issues in French society.

A new anthropology of Islam
\"In this powerful but accessible new study John Bowen draws on a full range of work in social anthropology to present Islam in ways that emphasise its constitutive practices, from praying and learning to judging and political organising. Starting at the heart of Islam - revelation and learning in Arabic lands - Bowen shows how Muslims have adapted Islamic texts and traditions to ideas and conditions in the societies in which they live. Returning to key case studies in Indonesia, Africa, Pakistan and Western Europe to explore each major domain of Islamic religious and social life, Bowen also considers the theoretical advances in social anthropology that have come out of the study of Islam. A New Anthropology of Islam is essential reading for all those interested in the study of Islam and for those following new developments in the discipline of anthropology\"-- Provided by publisher.

Pathogen reduction of monkeypox virus in plasma and whole blood using riboflavin and UV light
Monkeypox virus has recently emerged from endemic foci in Africa and, since October 20, 2022, more than 73,000 human infections have been reported by the CDC from over 100 countries that historically have not reported monkeypox cases. The detection of virus in skin lesions, blood, semen, and saliva of infected patients with monkeypox infections raises the potential for disease transmission via routes that have not been previously documented, including by blood and plasma transfusions. Methods for protecting the blood supply against the threats of newly emerging disease agents exist and include Pathogen Reduction Technologies (PRT) which utilize photochemical treatment processes to inactivate pathogens in blood while preserving the integrity of plasma and cellular components. Such methods have been employed broadly for over 15 years, but effectiveness of these methods under routine use conditions against monkeypox virus has not been reported.
Monkeypox virus (strain USA_2003) was used to inoculate plasma and whole blood units that were then treated with riboflavin and UV light (Mirasol Pathogen Reduction Technology System, Terumo BCT, Lakewood, CO). The infectious titers of monkeypox virus in the samples before and after riboflavin + UV treatment were determined by plaque assay on Vero cells.
The levels of spiked virus present in whole blood and plasma samples exceeded 103 infectious particles per dose, corresponding to greater than 105 DNA copies per mL. Treatment of whole blood and plasma units under standard operating procedures for the Mirasol PRT System resulted in complete inactivation of infectivity to the limits of detection. This is equivalent to a reduction of ≥ 2.86 +/- 0.73 log10 pfu/mL of infectivity in whole blood and ≥ 3.47 +/-0.19 log10 pfu/mL of infectivity in plasma under standard operating conditions for those products.
Based on this data and corresponding studies on infectivity in patients with monkeypox infections, use of Mirasol PRT would be expected to significantly reduce the risk of transfusion transmission of monkeypox.

Pathogen reduction of SARS-CoV-2 virus in plasma and whole blood using riboflavin and UV light
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has recently been identified as the causative agent for Coronavirus Disease 2019 (COVID-19). The ability of this agent to be transmitted by blood transfusion has not been documented, although viral RNA has been detected in serum. Exposure to treatment with riboflavin and ultraviolet light (R + UV) reduces blood-borne pathogens while maintaining blood product quality. Here, we report on the efficacy of R + UV in reducing SARS-CoV-2 infectivity when tested in human plasma and whole blood products.
SARS-CoV-2 (isolate USA-WA1/2020) was used to inoculate plasma and whole blood units that then underwent treatment with riboflavin and UV light (Mirasol Pathogen Reduction Technology System, Terumo BCT, Lakewood, CO). The infectious titers of SARS-CoV-2 in the samples before and after R + UV treatment were determined by plaque assay on Vero E6 cells. Each plasma pool (n = 9) underwent R + UV treatment performed in triplicate using individual units of plasma and then repeated using individual whole blood donations (n = 3).
Riboflavin and UV light reduced the infectious titer of SARS-CoV-2 below the limit of detection for plasma products at 60-100% of the recommended energy dose. At the UV light dose recommended by the manufacturer, the mean log reductions in the viral titers were ≥ 4.79 ± 0.15 Logs in plasma and 3.30 ± 0.26 in whole blood units.
Riboflavin and UV light effectively reduced the titer of SARS-CoV-2 to the limit of detection in human plasma and by 3.30 ± 0.26 on average in whole blood. Two clades of SARS-CoV-2 have been described and questions remain about whether exposure to one strain confers strong immunity to the other. Pathogen-reduced blood products may be a safer option for critically ill patients with COVID-19, particularly those in high-risk categories.

Evaluation of shedding, tissue burdens, and humoral immune response in goats after experimental challenge with the virulent Brucella melitensis strain 16M and the reduced virulence vaccine strain Rev. 1
Brucella melitensis is the causative agent of brucellosis in small ruminants and is of considerable economic and public health importance in many countries worldwide. The control of disease in humans depends on the control of disease in livestock; however, few counties with endemic B. melitensis infection have been able to successfully eradicate this pathogen. This underscores the need for further research on the pathogenesis of both virulent and vaccine strains of B. melitensis in the small ruminant host. The aim of the present study was to characterize clinical effects, tissue colonization, shedding, and humoral immune response following B. melitensis infection in goats. Both virulent (16M) and reduced virulence (Rev. 1) strains of B. melitensis were studied. Pregnant goats were infected at 11-14 weeks of gestation with 8 x 106 or 8 x 107 CFU of B. melitensis. Infection of goats with B. melitensis 16M resulted in an 86% abortion rate. This strain disseminated widely in pregnant does post-infection with none of the 15 sampled tissues spared from colonization. Importantly, we report the first isolation of B. melitensis from muscle tissue in ruminants. Pathogenesis of Rev. 1 infection was variable with two does showing minimal colonization and one doe exhibiting disease similar to that of animals infected with fully virulent 16M. Shedding of B. melitensis in milk occurred in all 16M- and Rev. 1- infected goats. In pregnant animals challenged with virulent B. melitensis, median time to seroconversion was 21 days; however, 2 animals did not seroconvert until after abortion.

SARS-CoV-2 evolution in animals suggests mechanisms for rapid variant selection
SARS-CoV-2 spillback from humans into domestic and wild animals has been well documented, and an accumulating number of studies illustrate that human-to-animal transmission is widespread in cats, mink, deer, and other species. Experimental inoculations of cats, mink, and ferrets have perpetuated transmission cycles. We sequenced full genomes of Vero cell–expanded SARS-CoV-2 inoculum and viruses recovered from cats (n = 6), dogs (n = 3), hamsters (n = 3), and a ferret (n = 1) following experimental exposure. Five nonsynonymous changes relative to the USA-WA1/2020 prototype strain were near fixation in the stock used for inoculation but had reverted to wild-type sequences at these sites in dogs, cats, and hamsters within 1- to 3-d postexposure. A total of 14 emergent variants (six in nonstructural genes, six in spike, and one each in orf8 and nucleocapsid) were detected in viruses recovered from animals. This included substitutions in spike residues H69, N501, and D614, which also vary in human lineages of concern. Even though a live virus was not cultured from dogs, substitutions in replicase genes were detected in amplified sequences. The rapid selection of SARS-CoV-2 variants in vitro and in vivo reveals residues with functional significance during host switching. These observations also illustrate the potential for spillback from animal hosts to accelerate the evolution of new viral lineages, findings of particular concern for dogs and cats living in households with COVID-19 patients. More generally, this glimpse into viral host switching reveals the unrealized rapidity and plasticity of viral evolution in experimental animal model systems.
