Assessing biomarkers of remission in female patients with anorexia nervosa (REMANO): a protocol for a prospective cohort study with a nested case-control study using clinical, neurocognitive, biological, genetic, epigenetic and neuroimaging markers in a French specialised inpatient unit.

Background: Anorexia nervosa (AN) is a severe psychiatric disorder associated with frequent relapses and variability in treatment responses. Previous literature suggested that such variability is influenced by premorbid vulnerabilities such as abnormalities of the reward system. Several factors may indicate these vulnerabilities, such as neurocognitive markers (tendency to favour delayed reward, poor cognitive flexibility, abnormal decision process), genetic and epigenetic markers, biological and hormonal markers, and physiological markers.

[From nursing to changing social representations: the study of health literacy in psychiatry].

The Litterapsy study focuses on the assessment of health literacy in patients with psychiatric disorders, a field that has been little studied in France. It is based on the observations of an advanced practice nurse specializing in psychosocial rehabilitation. Its aim is to provide objective data to better understand how these patients understand medical information and navigate the healthcare system.

Lower anti-Müllerian hormone levels are associated with HIV in reproductive age women and shorter leukocyte telomere length among late reproductive age women.

Objectives: We sought to better understand factors associated with ovarian aging in women with HIV (WWH).

Design: HIV has been associated with diminished fertility, younger age at menopause, and shorter leukocyte telomere length (LTL), a marker of cellular aging. We herein examine cross-sectional and longitudinal associations between LTL, anti-Müllerian hormone (AMH), and HIV.

[Development of a psychiatric care facility into a Covid unit].

Covid-19 did not spare the psychiatric care services. At the Sainte-Anne Hospital, as in the medicine-surgery-obstetrics departments, several care units had to be transformed and organised in order to accommodate positive patients who did not need to be admitted to intensive care. Feedback on the transformation of a care structure of the "Clinique des maladies mentales et de l'encéphale" for more than two months.

Inverse relationship between leukocyte telomere length attrition and blood mitochondrial DNA content loss over time.

Leukocyte telomere length (LTL) and whole blood mitochondrial DNA (WB mtDNA) content are aging markers impacted by chronic diseases such as human immunodeficiency virus (HIV) infection. We characterized the relationship between these two markers in 312 women ≥12 years of age living with HIV and 300 HIV-negative controls. We found no relationship between the two markers cross-sectionally.

A novel ischemia reperfusion injury hereditary tissue model for pressure ulcers progression.

Ischemia reperfusion injury (IRI) involvement in pressure ulcers (PU) progression via a surge of oxidative stress and inflammatory responses is well documented. IRI strongly depends on the mechanical loading history. We present a generalized IRI model considering external loading, dynamic tissue healing capacity, accumulating mechanical and reperfusion-mediated damages and competing repair processes of saturating nature.

Expression of human TLR4/myeloid differentiation factor 2 directs an early innate immune response associated with modest increases in bacterial burden during infection.

Human TLR4 (hTLR4) and mouse TLR4 molecules respond differently to hypo-acylated LPS. The LPS of is hypo-acylated and heavily glycosylated and causes a minimal response by human cells. Thus, we hypothesized that mice expressing hTLR4 molecules would be more susceptible to infection.

The beginning of a new era: treatment of erectile dysfunction by use of physical energies as an alternative to pharmaceuticals.

This introductory manuscript aims to familiarize the concept of the ability of certain forces or energies applied on the penis. This concept is described and discussed in more detail for three optional applicative energies; shock wave energy via mechano-transduction, ultrasound energy via its theoretical unique effect on the cellular membrane, specifically cyclic separation of the two phospholipid layers, creating biochemical, functional and structural tissue changes. Radio frequency energy via its heating effect is proven to induce immediate changes on collagen strucures and on realignment of collagen fibers, as well as induction of local vasodilation.

Absence of Collaterals is Associated with Larger Infarct Volume and Worse Outcome in Patients with Large Vessel Occlusion and Mild Symptoms.

Background: Mechanical thrombectomy is the standard of care for patients with large vessel occlusion (LVO) presenting with severe symptoms; however, little is known about the best treatment for patients with LVO and mild symptoms. The absence of good collaterals has been associated with a worse outcome in patients with LVO. In this study, we aim to assess the use of collateral score to identify patients with LVO and mild symptoms that might benefit from mechanical thrombectomy (MT).

Cell-Type-Selective Effects of Intramembrane Cavitation as a Unifying Theoretical Framework for Ultrasonic Neuromodulation.

Diverse translational and research applications could benefit from the noninvasive ability to reversibly modulate (excite or suppress) CNS activity using ultrasound pulses, however, without clarifying the underlying mechanism, advanced design-based ultrasonic neuromodulation remains elusive. Recently, intramembrane cavitation within the bilayer membrane was proposed to underlie both the biomechanics and the biophysics of acoustic bio-effects, potentially explaining cortical stimulation results through a neuronal intramembrane cavitation excitation (NICE) model. Here, NICE theory is shown to provide a detailed predictive explanation for the ability of ultrasonic (US) pulses to also suppress neural circuits through cell-type-selective mechanisms: according to the predicted mechanism T-type calcium channels boost charge accumulation between short US pulses selectively in low threshold spiking interneurons, promoting net cortical network inhibition.

Type I Interferon Counters or Promotes Coxiella burnetii Replication Dependent on Tissue.

Coxiella burnetii is an intracellular pathogen and the cause of Q fever. Gamma interferon (IFN-γ) is critical for host protection from infection, but a role for type I IFN in C. burnetii infection has not been determined.

Amphotericin B stimulates γδ T and NK cells, and enhances protection from Salmonella infection.

Amphotericin B (AmB) is a commonly used antifungal drug, with well-documented effects on cellular immune responses. We determined that AmB-stimulated γδ T-cell activation and proliferation in vitro at very low concentrations. AmB also enhanced IFN-γ production by NK cells in combination with IL-18.

Extracorporeal acute cardiac pacing by high intensity focused ultrasound.

Ultrasound has been shown to produce Premature Ventricular Contractions (PVC's). Two clinical applications in which acute cardiac pacing by ultrasound may be valuable are: (1) preoperative patient screening in cardiac resynchronization therapy surgery; (2) Emergency life support, following an event of sudden death, caused by cardiac arrest. Yet, previously the demonstrated mean success rate of extra-systole induction by High Intensity Focused Ultrasound (HIFU) in rats is below 4.

Oral delivery of oligomeric procyanidins in Apple Poly® enhances type I IFN responses in vivo.

Type I IFN signaling is a central pathway that provides critical innate protection from viral and bacterial infection and can have regulatory outcomes in inflammatory settings. We determined previously that OPCs contained in the dietary supplement APP enhanced responses to type I IFN in vitro. Here, we confirm that OPCs from two different sources significantly increased pSTAT1, whereas a monomeric form of procyanidin did not.

GnpIS: an information system to integrate genetic and genomic data from plants and fungi.

Data integration is a key challenge for modern bioinformatics. It aims to provide biologists with tools to explore relevant data produced by different studies. Large-scale international projects can generate lots of heterogeneous and unrelated data.

Solute carrier 11A1 is expressed by innate lymphocytes and augments their activation.

Solute carrier 11A1 (SLC11A1) is a divalent ion transporter formerly known as the natural resistance-associated macrophage protein (NRAMP1) and the Bcg/Lsh/Ity locus. SLC11A1 was thought to be exclusively expressed in monocyte/macrophages and to have roles in phagosome maturation and cell activation. We characterized the expression of SLC11A1 in the majority of human and bovine γδ T cells and NK cells and in human CD3(+)CD45RO(+) T cells.

Low intensity ultrasound perturbs cytoskeleton dynamics.

Therapeutic ultrasound is widely employed in clinical applications but its mechanism of action remains unclear. Here we report prompt fluidization of a cell and dramatic acceleration of its remodeling dynamics when exposed to low intensity ultrasound. These physical changes are caused by very small strains (10) at ultrasonic frequencies (10 Hz), but are closely analogous to those caused by relatively large strains (10) at physiological frequencies (10 Hz).

Towards multifocal ultrasonic neural stimulation II: design considerations for an acoustic retinal prosthesis.

Ultrasound waves, widely used as a non-invasive diagnostic modality, were recently shown to stimulate neuronal activity. Functionally meaningful stimulation, as is required in order to form a unified percept, requires the dynamic generation of simultaneous stimulation patterns. In this paper, we examine the general feasibility and properties of an acoustic retinal prosthesis, a new vision restoration strategy that will combine ultrasonic neuro-stimulation and ultrasonic field sculpting technology towards non-invasive artificial stimulation of surviving neurons in a degenerating retina.

Oligomeric procyanidins stimulate innate antiviral immunity in dengue virus infected human PBMCs.

Oligomeric procyanidins (OPCs) have been shown to have antiviral and immunostimulatory effects. OPCs isolated from non-ripe apple peel were tested for capacity to reduce dengue virus (DENV) titers. Similar to published accounts, OPCs exhibited direct antiviral activity.
