Mitotic inheritance of genetic and epigenetic information via the histone H3.1 variant.

The replication-dependent histone H3.1 variant, ubiquitous in multicellular eukaryotes, has been proposed to play key roles during chromatin replication due to its unique expression pattern restricted to the S phase of the cell cycle. Here, we describe recent discoveries in plants regarding molecular mechanisms and cellular pathways involving H3.

Weight gain following the single substitution of tenofovir disoproxil fumarate by tenofovir alafenamide in HIV-infected people from the French Dat'AIDS cohort: A propensity score-matched analysis.

Objectives: To minimize confounding factors, we aimed to describe the changes in weight and body mass index (BMI) following the single substitution of tenofovir disoproxil fumarate (TDF) by tenofovir alafenamide (TAF) in people living with HIV (PLWH).

Methods: We designed a retrospective study in a large French cohort. We included all HIV-suppressed adults under TDF + emtricitabine + rilpivirine or elvitegravir/cobistat, who experienced a first switch from TDF to TAF, while other antiretrovirals remained unchanged (Switch group).

Latent classes of neurodevelopmental profiles and needs in children and adolescents with prenatal alcohol exposure.

Background: Fetal alcohol spectrum disorder (FASD) resulting from prenatal alcohol exposure (PAE) is a common neurodevelopmental disorder, but substantial interindividual heterogeneity complicates timely and accurate assessment, diagnosis, and intervention. The current study aimed to identify classes of children and adolescents with PAE assessed for FASD according to their pattern of significant neurodevelopmental functioning across 10 domains using latent class analysis (LCA), and to characterize these subgroups across clinical features.

Methods: Data from the Canadian National FASD Database, a large ongoing repository of anonymized clinical data received from diagnostic clinics across Canada, was analyzed using a retrospective cross-sectional cohort design.

Myocarditis in monkeypox-infected patients: a case series.

Objectives: Monkeypox, a zoonotic orthopoxvirus, has spread to many countries in recent months, involving mostly men who have sex with men with multiple partners. Clinical presentation includes skin lesions, systemic signs, and less frequent skin superinfections or anorectal and ophthalmic involvements. We aim to detail cases of myocarditis attributable to monkeypox, an entity that has been poorly described.

Adaptive behavior, sleep, and physical activity in adolescents with fetal alcohol spectrum disorder.

Background: Fetal alcohol spectrum disorder (FASD) is broadly associated with impairments to adaptive behavior and dysfunctional sleep. Associations between sleep, adaptive behavior, and physical activity are frequently drawn in discussions of typical development and other clinical conditions.

Aims: In this study, we sought to characterize patterns of sleep, adaptive behavior, and physical activity in adolescents with FASD.

Clinical characteristics of ambulatory and hospitalized patients with monkeypox virus infection: an observational cohort study.

Objectives: A global outbreak of monkeypox virus infections in human beings has been described since April 2022. The objectives of this study were to describe the clinical characteristics and complications of patients with a monkeypox infection.

Methods: All consecutive patients with a polymerase chain reaction (PCR)-confirmed monkeypox infection seen in a French referral centre were included.

Novel mutations in antiviral multiresistant HSV-2 genital lesion: A case report.

HSV-2 antiviral resistance mainly occurs in immunocompromised patients and especially in HIV-positive individuals receiving long-term antiviral treatment. Those situations can be challenging as few alternatives are available for HSV infection management. To describe clinical and virological significance of two novel potential HSV-2 resistance mutations after treating an obese patient with a pseudotumoral genital HSV-related lesion.

Treatment With a Three-Drug Regimen for Pulmonary Tuberculosis Based on Rapid Molecular Detection of Isoniazid Resistance: A Noninferiority Randomized Trial (FAST-TB).

Background: The rationale behind the use of ethambutol in the standard tuberculosis treatment is to prevent the emergence of resistance to rifampicin in case of primary resistance to isoniazid. We evaluated whether early detection of isoniazid resistance using molecular testing allows the use an ethambutol-free regimen.

Methods: FAST-TB, a phase 4, French, multicenter, open-label, non-inferiority trial, compared 2 strategies: (1) polymerase chain reaction (PCR)-based detection of isoniazid and rifampicin resistance at baseline using Genotype MTBDR version 2.

The histone H3.1 variant regulates TONSOKU-mediated DNA repair during replication.

The tail of replication-dependent histone H3.1 varies from that of replication-independent H3.3 at the amino acid located at position 31 in plants and animals, but no function has been assigned to this residue to demonstrate a unique and conserved role for H3.

Dolutegravir-based dual maintenance regimens combined with lamivudine/emtricitabine or rilpivirine: risk of virological failure in a real-life setting.

Background: Maintenance ART with dolutegravir-based dual regimens have proved their efficacy among HIV-1-infected subjects in randomized trials. However, real-life data are scarce, with limited populations and follow-up.

Objectives: We assessed virological failure (VF) and resistance-associated mutations (RAMs) on dolutegravir maintenance regimens in combination with rilpivirine or with lamivudine or emtricitabine (xTC) and analysed the factors associated with VF.

Anomalous spin relaxation in graphene nanostructures on the high temperature annealed surface of hydrogenated diamond nanoparticles.

The electronic and magnetic structures of diamond nanoparticles with a hydrogenated surface are investigated as a function of annealing temperature under vacuum annealing up to 800-1000 °C. Near edge X-ray absorption fine structure (NEXAFS) spectra together with elemental analysis show successive creation of defect-induced nonbonding surface states at the expense of surface-hydrogen atoms as the annealing temperature is increased above 800 °C. Magnetization and ESR spectra confirm the increase in the concentration of localized spins assigned to the nonbonding surface states upon the increase of the annealing temperature.

Prevalence of genotypic baseline risk factors for cabotegravir + rilpivirine failure among ARV-naive patients.

Background: Multivariable baseline factor analysis across cabotegravir + rilpivirine clinical trials showed that HIV-1 subtypes A6/A1 and the presence of rilpivirine resistance-associated mutations (RAMs) were associated with an increased risk of virological failure of this dual therapy. The aim of this study was to describe the prevalence of genotypic baseline risk factors for cabotegravir + rilpivirine failure among ARV-naive patients.

Patients And Methods: From 2010 to 2020, 4212 sequences from ARV-naive patients were collected from three large Parisian academic hospital genotypic databases.

H3.1K27me1 maintains transcriptional silencing and genome stability by preventing GCN5-mediated histone acetylation.

Epigenetic mechanisms play diverse roles in the regulation of genome stability in eukaryotes. In Arabidopsis thaliana, genome stability is maintained during DNA replication by the H3.1K27 methyltransferases ARABIDOPSIS TRITHORAX-RELATED PROTEIN 5 (ATXR5) and ATXR6, which catalyze the deposition of K27me1 on replication-dependent H3.
