Zanamivir and baloxavir combination to cure persistent influenza and coronavirus infections after hematopoietic stem cell transplant.

Objectives: Immunocompromised patients may experience prolonged shedding of influenza virus potentially leading to severe infections. Alternatives to monotherapy with neuraminidase inhibitors should be evaluated to entirely suppress viral replication and prevent drug-resistant mutations.

Methods: We investigated the clinical and virological evolution in a case of persistent influenza A and human coronavirus OC43 (HCoV-OC43) coinfection in a hematopoietic stem cell transplant recipient after different therapeutic strategies.

Resolving Discrepancies between State-of-the-Art Theory and Experiment for HO + HO via Multiscale Informatics.

Recent high-level theoretical calculations predict a mild temperature dependence for HO + HO inconsistent with state-of-the-art experimental determinations that upheld the stronger temperature dependence observed in early experiments. Via MultiScale Informatics analysis of the theoretical and experimental data, we identified an alternative interpretation of the raw experimental data that uses HO + HO rate constants nearly identical to theoretical predictions─implying that the theoretical and experimental data are actually consistent, at least when considering the raw data from experimental studies. Similar analyses of typical signals from low-temperature experiments indicate that an HOOOOH intermediate─identified by recent theory but absent from earlier interpretations─yields modest effects that are smaller than, but may have contributed to, the scatter in data among different experiments.

[The immediate impact of Covid-19 infection and the resulting lockdown on nursing home residents].

Introduction: Following the Covid-19 epidemic affecting 76 of the 97 residents (78.3 %) in a French nursing home, we assessed the impact of this cluster period on the physical and psycho-cognitive health of the residents, expecting in particular to observe effects that were dependent on their state of cognitive-behavioural dependence.

Methods: We retained twenty-two variables, 5 relating to demographic data, 6 to the specific care linked to Covid-19 infection, 6 to somatic pathologies and psycho-behavioural disturbances before the epidemic and 5 to the period following it.

Efficiency and Persistence of Movento Treatment against and the Transmission of Aphid-Borne Viruses.

Neonicotinoids are widely used to protect fields against aphid-borne viral diseases. The recent ban of these chemical compounds in the European Union has strongly impacted rapeseed and sugar beet growing practices. The poor sustainability of other insecticide families and the low efficiency of prophylactic methods to control aphid populations and pathogen introduction strengthen the need to characterize the efficiency of new plant protection products targeting aphids.

Introductions and early spread of SARS-CoV-2 in France, 24 January to 23 March 2020.

Following SARS-CoV-2 emergence in China, a specific surveillance was implemented in France. Phylogenetic analysis of sequences retrieved through this surveillance suggests that detected initial introductions, involving non-clade G viruses, did not seed local transmission. Nevertheless, identification of clade G variants subsequently circulating in the country, with the earliest from a patient who neither travelled to risk areas nor had contact with travellers, suggests that SARS-CoV-2 might have been present before the first recorded local cases.

A decrease in anaerobic bacteria promotes overgrowth while β-glucan treatment restores the gut microbiota and attenuates colitis.

Background: The intestinal microbiota plays a crucial role in the maintenance of gut homeostasis. Changes in crosstalk between the intestinal epithelial cells, immune cells and the microbiota are critically involved in the development of inflammatory bowel disease. In the experimental mouse model, the development of colitis induced by dextran sulfate sodium (DSS) promotes overgrowth of the opportunistic yeast pathogen .

Improved upper limits on the stochastic gravitational-wave background from 2009-2010 LIGO and Virgo data.

Gravitational waves from a variety of sources are predicted to superpose to create a stochastic background. This background is expected to contain unique information from throughout the history of the Universe that is unavailable through standard electromagnetic observations, making its study of fundamental importance to understanding the evolution of the Universe. We carry out a search for the stochastic background with the latest data from the LIGO and Virgo detectors.

Riboregulation of the bacterial actin-homolog MreB by DsrA small noncoding RNA.

The bacterial actin-homolog MreB is a key player in bacterial cell-wall biosynthesis and is required for the maintenance of the rod-like morphology of Escherichia coli. However, how MreB cellular levels are adjusted to growth conditions is poorly understood. Here, we show that DsrA, an E.

Search for gravitational waves associated with γ-ray bursts detected by the interplanetary network.

We present the results of a search for gravitational waves associated with 223 γ-ray bursts (GRBs) detected by the InterPlanetary Network (IPN) in 2005-2010 during LIGO's fifth and sixth science runs and Virgo's first, second, and third science runs. The IPN satellites provide accurate times of the bursts and sky localizations that vary significantly from degree scale to hundreds of square degrees. We search for both a well-modeled binary coalescence signal, the favored progenitor model for short GRBs, and for generic, unmodeled gravitational wave bursts.

[Familial study of Hb A2 Babinga (delta 136 Glyc----Asp) in South America].

In November 1983, HB A2 Babinga was found in a Columbian male in Paris. Blood samples from Columbia showed that his mother and one of his brothers were also Hb A2 Babinga carriers and that his mother and another brother and his sister were Hb S carriers.

[Captopril induced lichenoid eruption].

The authors report three cases of Captopril induced lichenoid eruption, already unmentionned, as far as they know. This cutaneous adverse reaction seemed to be dose related. Late onset was possible, even after six months of therapy.

[Captopril-induced eruptions: occurrence over a 3-year period].

With an informatized sample of 123 patients taking Captopril and treated for a total duration of 1,321 month/patients, the frequency of the dermatological symptoms induced by the drug is related. Pruritus is found in 10,5 p. 100 and rashes in 2,4 p.
