Digital AVATAR therapy for distressing voices in psychosis: the phase 2/3 AVATAR2 trial

Philippa Garety, Clementine Edwards, Hassan Jafari et al. · 2024 · Nature Medicine

Distressing voices are a core symptom of psychosis, for which existing treatments are currently suboptimal; as such, new effective treatments for distressing voices are needed. AVATAR therapy involves voice-hearers engaging in a series of facilitated dialogues with a digital embodiment of the distressing voice. This randomized phase 2/3 trial assesses the efficacy of two forms of AVATAR therapy, AVATAR-Brief (AV-BRF) and AVATAR-Extended (AV-EXT), both combined with treatment as usual (TAU) compared to TAU alone, and conducted an intention-to-treat analysis. We recruited 345 participants with p

Multiple sclerosis: molecular pathogenesis and therapeutic intervention

Imane Boutitah-Benyaich, Herena Eixarch, Javier Villacieros‐Álvarez et al. · 2025 · Signal Transduction and Targeted Therapy

Multiple sclerosis is a chronic immune-mediated disorder of the central nervous system characterized by demyelination, axonal loss, and neuroinflammation, culminating in progressive neurological disability. Despite significant advances in understanding its immunopathogenesis, current immunotherapies remain limited in their ability to halt disease progression, making multiple sclerosis incurable and highlighting the critical need for novel therapeutic strategies. Antigen-specific immunotherapy represents a groundbreaking approach that aims to restore immune tolerance to myelin-derived antigens

Comparison of joint versus purebred genomic evaluation in the French multi-breed dairy goat population

Céline Carillier, Hélène Larroque, Christèle Robert-Granié · 2014 · Genetics Selection Evolution

BACKGROUND: All progeny-tested bucks from the two main French dairy goat breeds (Alpine and Saanen) were genotyped with the Illumina goat SNP50 BeadChip. The reference population consisted of 677 bucks and 148 selection candidates. With the two-step approach based on genomic best linear unbiased prediction (GBLUP), prediction accuracy of candidates did not outperform that of the parental average. We investigated a GBLUP method based on a single-step approach, with or without blending of the two breeds in the reference population. METHODS: Three models were used: (1) a multi-breed model, in whi

Phylogeographic Pattern and Extensive Mitochondrial DNA Divergence Disclose a Species Complex within the Chagas Disease Vector Triatoma dimidiata

Fernando A. Monteiro, Т. Е. Перетолчина, Cristiano Lazoski et al. · 2013 · PLoS ONE

BACKGROUND: Triatoma dimidiata is among the main vectors of Chagas disease in Latin America. However, and despite important advances, there is no consensus about the taxonomic status of phenotypically divergent T. dimidiata populations, which in most recent papers are regarded as subspecies. METHODOLOGY AND FINDINGS: A total of 126 cyt b sequences (621 bp long) were produced for specimens from across the species range. Forty-seven selected specimens representing the main cyt b clades observed (after a preliminary phylogenetic analysis) were also sequenced for an ND4 fragment (554 bp long) and

Mesenchymal stem cells internalize Mycobacterium tuberculosis through scavenger receptors and restrict bacterial growth through autophagy

Arshad Khan, Lovepreet K. Mann, Ramesha Papanna et al. · 2017 · Scientific Reports

Human mesenchymal stem cells (MSCs) express scavenger receptors that internalize lipids, including oxidized low-density lipoprotein (oxLDL). We report that MSCs phagocytose Mycobacterium tuberculosis (Mtb) through two types of scavenger receptors (SRs; MARCO and SR-B1), as blockade of the receptors with antibodies or siRNA knockdown decreased the uptake of Mtb. MSCs also expressed mannose receptor (MR) that was found to endocytose rhodamine-labeled mannosylated BSA (rMBSA), though the receptor was not involved in the uptake of Mtb. Dil-oxLDL and rMBSA taken up into MSC endosomes colocalized wi

Infection Dynamic of Symbiotic Bacteria in the Pea Aphid Acyrthosiphon pisum Gut and Host Immune Response at the Early Steps in the Infection Process

François Renoz, Christine Noël, Abdelmounaim Errachid et al. · 2015 · PLoS ONE

In addition to its obligatory symbiont Buchnera aphidicola, the pea aphid Acyrthosiphon pisum can harbor several facultative bacterial symbionts which can be mutualistic in the context of various ecological interactions. Belonging to a genus where many members have been described as pathogen in invertebrates, Serratia symbiotica is one of the most common facultative partners found in aphids. The recent discovery of strains able to grow outside their host allowed us to simulate environmental acquisition of symbiotic bacteria by aphids. Here, we performed an experiment to characterize the A. pis

Mix it and fix it: functions of composite olfactory signals in ring-tailed lemurs

Lydia K. Greene, Kathleen E. Grogan, Kendra Smyth et al. · 2016 · Royal Society Open Science

Animals communicating via scent often deposit composite signals that incorporate odorants from multiple sources; however, the function of mixing chemical signals remains understudied. We tested both a 'multiple-messages' and a 'fixative' hypothesis of composite olfactory signalling, which, respectively, posit that mixing scents functions to increase information content or prolong signal longevity. Our subjects-adult, male ring-tailed lemurs (Lemur catta)-have a complex scent-marking repertoire, involving volatile antebrachial (A) secretions, deposited pure or after being mixed with a squalene-

Genetic evidence that lower circulating FSH levels lengthen menstrual cycle, increase age at menopause and impact female reproductive health

Katherine S. Ruth, Robin N. Beaumont, Jessica Tyrrell et al. · 2016 · Human Reproduction

STUDY QUESTION: How does a genetic variant in the FSHB promoter, known to alter FSH levels, impact female reproductive health? SUMMARY ANSWER: The T allele of the FSHB promoter polymorphism (rs10835638; c.-211G>T) results in longer menstrual cycles and later menopause and, while having detrimental effects on fertility, is protective against endometriosis. WHAT IS KNOWN ALREADY: The FSHB promoter polymorphism (rs10835638; c.-211G>T) affects levels of FSHB transcription and, as a result, circulating levels of FSH. FSH is required for normal fertility and genetic variants at the FSHB locus are as
