Unlocking secrets of microbial ecotoxicology: recent achievements and future challenges.

Environmental pollution is one of the main challenges faced by humanity. By their ubiquity and vast range of metabolic capabilities, microorganisms are affected by pollution with consequences on their host organisms and on the functioning of their environment. They also play key roles in the fate of pollutants through the degradation, transformation, and transfer of organic or inorganic compounds.

Influence of Culprit Lesion Intervention on Outcomes in Infarct-Related Cardiogenic Shock With Cardiac Arrest.

Background: Cardiac arrest (CA) is common in patients with infarct-related cardiogenic shock (CS).

Objectives: The goal of this study was to identify the characteristics and outcomes of culprit lesion percutaneous coronary intervention (PCI) of patients with infarct-related CS stratified according to CA in the CULPRIT-SHOCK (Culprit Lesion Only PCI Versus Multivessel PCI in Cardiogenic Shock) randomized trial and registry.

Methods: Patients with CS with and without CA from the CULPRIT-SHOCK study were analyzed.

Loss of brainstem white matter predicts onset and motor neuron symptoms in C9orf72 expansion carriers: a GENFI study.

Background And Objectives: The C9orf72 expansion is the most common genetic cause of frontotemporal dementia (FTD) and/or motor neuron disease (MND). Corticospinal degeneration has been described in post-mortem neuropathological studies in these patients, especially in those with MND. We used MRI to analyze white matter (WM) volumes in presymptomatic and symptomatic C9orf72 expansion carriers and investigated whether its measure may be helpful in predicting the onset of symptoms.

[Autoinflammatory diseases associated with RIPK1 mutations: A review of the literature].

Autoinflammatory diseases related to RIPK1 mutations have been recently described. Two distinct clinical phenotypes have been reported and depend on the type and location of the mutation. When the mutation is recessive with loss of function, patients develop a combined phenotype of immune deficiency with recurrent bacterial and fungal infections and signs of early inflammatory bowel disease, non-erosive polyarthritis and growth retardation.

In Vivo Live Imaging of Axonal Transport in Developing Zebrafish Axons.

Axonal transport is crucial for neuronal homeostasis, survival, and development. Indeed, axonal transport needs to be precisely regulated for developing axons to swiftly and accurately respond to their complex and evolving environment in space and time. A growing number of studies have started to unravel the diversity of regulatory and adaptor proteins required to orchestrate the axonal transport machinery.

Impact of an intensive multimodal educative program on behavioral disorders of polyhandicapped patients: A randomized controlled trial.

Background: Hospitalized children and young adults with polyhandicap (PLH) often present with behavioral and relational disorders that are mainly related to their difficulties in communicating and interacting with their environments. Educational support is rarely provided to these patients. An intensive multimodal educative program could help in reducing behavioral disorders and in improving the quality of life of healthcare workers, including nurses and auxiliary nurses.

Deciphering Responses to PPV Infection: A Way toward the Use of Metabolomics Approach for the Diagnostic of Sharka Disease.

Sharka disease, caused by (PPV), induces several changes in . In leaf tissues, the infection may cause oxidative stress and disrupt the photosynthetic process. Moreover, several defense responses can be activated after PPV infection and have been detected at the phytohormonal, transcriptomic, proteomic, and even translatome levels.

Blood microbiota and metabolomic signature of major depression before and after antidepressant treatment: a prospective case-control study.

Background: The microbiota interacts with the brain through the gut-brain axis, and a distinct dysbiosis may lead to major depressive episodes. Bacteria can pass through the gut barrier and be found in the blood. Using a multiomic approach, we investigated whether a distinct blood microbiome and metabolome was associated with major depressive episodes, and how it was modulated by treatment.

Human and preclinical studies of the host-gut microbiome co-metabolite hippurate as a marker and mediator of metabolic health.

Objective: Gut microbial products are involved in regulation of host metabolism. In human and experimental studies, we explored the potential role of hippurate, a hepatic phase 2 conjugation product of microbial benzoate, as a marker and mediator of metabolic health.

Design: In 271 middle-aged non-diabetic Danish individuals, who were stratified on habitual dietary intake, we applied H-nuclear magnetic resonance (NMR) spectroscopy of urine samples and shotgun-sequencing-based metagenomics of the gut microbiome to explore links between the urine level of hippurate, measures of the gut microbiome, dietary fat and markers of metabolic health.

Characterizing the culturable surface microbiomes of diverse marine animals.

Biofilm-forming bacteria have the potential to contribute to the health, physiology, behavior and ecology of the host and serve as its first line of defense against adverse conditions in the environment. While metabarcoding and metagenomic information furthers our understanding of microbiome composition, fewer studies use cultured samples to study the diverse interactions among the host and its microbiome, as cultured representatives are often lacking. This study examines the surface microbiomes cultured from three shallow-water coral species and two whale species.

Enhancement of photocurrent by incorporation of Preyssler type polyoxometalate protected nanoparticles in polyporphyrin films.

The introduction of nanoparticles (MNPs) at the surface of cationic poly-porphyrin films, obtained by electrostatic interaction between the bis-porphyrin copolymer and the Preyssler type polyoxometalate P5W30@MNPs, enhances the photocurrent (up to 2.5-3 times greater as a function of the used nanoparticle).

Psychiatric symptoms in anti glutamic acid decarboxylase associated limbic encephalitis in adults: a systematic review.

Autoimmune Limbic Encephalitis (LE) is a relatively new category of immune-mediated diseases with a wide range of neuropsychiatric symptoms. LE associated with Glutamic Acid Decarboxylase (GAD) antibodies is difficult to diagnose due to its possible atypical presentation with neuropsychiatric and behavioral features. We performed a systematic review of literature and retrieved 21 cases of anti GAD-associated LE with neuropsychiatric signs.

Aquatic Viruses and Climate Change.

The viral component in aquatic systems clearly needs to be incorporated into future ocean and inland water climate models. Viruses have the potential to influence carbon and nutrient cycling in aquatic ecosystems significantly. Changing climate likely has both direct and indirect influence on virus-mediated processes, among them an impact on food webs, biogeochemical cycles and on the overall metabolic performance of whole ecosystems.

Patterns of first recurrence and outcomes in surgically treated women with vulvar cancer: results from FRANCOGYN study group.

Objective: Cancer of the vulva recurrences vary considerably over time and are influenced by several pathological, surgical and adjuvant therapeutic prognostic factors. However, limited information is available about patterns of disease recurrence and prognosis. We analysed patterns of vulvar cancer recurrence based on a large French multicentre database.

A new congenital multicore titinopathy associated with fast myosin heavy chain deficiency.

Congenital titinopathies are myopathies with variable phenotypes and inheritance modes. Here, we fully characterized, using an integrated approach (deep phenotyping, muscle morphology, mRNA and protein evaluation in muscle biopsies), two siblings with congenital multicore myopathy harboring three TTN variants predicted to affect titin stability and titin-myosin interactions. Muscle biopsies showed multicores, type 1 fiber uniformity and sarcomeric structure disruption with some thick filament loss.

Customized three-dimensionally printed mandibular external fixator.

The advent of customized three-dimensional (3D) printing allows the affordable manufacturing of sophisticated medical devices, thereby providing swift and simple solutions to specific needs in modern healthcare. Meanwhile, certain devices such as industrial mandibular external fixators (EFs) have become less and less available from medical device companies because of decreased indications. What is more, their handling is often complex.

DNA Methylation Bisubstrate Inhibitors Are Fast-Acting Drugs Active against Artemisinin-Resistant Parasites.

Malaria is the deadliest parasitic disease affecting over 200 million people worldwide. The increasing number of treatment failures due to multi-drug-resistant parasites in South-East Asia hinders the efforts for elimination. It is thus urgent to develop new antimalarials to contain these resistant parasites.

Fraser syndrome: review of the literature illustrated by a historical adult case.

Fraser syndrome (cryptophthalmos-syndactyly syndrome) is a rare autosomal recessive malformation disorder. The first description of the syndrome was reported by George Fraser in 1962. Diagnosis is based on the major and minor criteria established by van Haelst et al.

Stem Cell DNA Damage and Genome Mutation in the Context of Aging and Cancer Initiation.

Adult stem cells fuel tissue homeostasis and regeneration through their unique ability to self-renew and differentiate into specialized cells. Thus, their DNA provides instructions that impact the tissue as a whole. Since DNA is not an inert molecule, but rather dynamic, interacting with a myriad of chemical and physical factors, it encounters damage from both endogenous and exogenous sources.

[Monoclonal antibodies in neurology].

Therapeutic antibodies have been successfully developed in neurology. However, their efficacy needs to overcome a main hurdle that is their limited access to the brain. Moreover, the multifactorial characteristics of many neurological diseases complicate the identification of a specific target.

Distinct P2Y Receptors Mediate Extension and Retraction of Microglial Processes in Epileptic and Peritumoral Human Tissue.

Microglia exhibit multiple, phenotype-dependent motility patterns often triggered by purinergic stimuli. However, little data exist on motility of human microglia in pathological situations. Here we examine motility of microglia stained with a fluorescent lectin in tissue slices from female and male epileptic patients diagnosed with mesial temporal lobe epilepsy or cortical glioma (peritumoral cortex).
