Ingestion of Bacillus cereus spores dampens the immune response to favor bacterial persistence.

Strains of the Bacillus cereus (Bc) group are sporulating bacteria commonly associated with foodborne outbreaks. Spores are dormant cells highly resistant to extreme conditions. Nevertheless, the pathological processes associated with the ingestion of either vegetative cells or spores remain poorly understood.

The Global Impact of Multisystemic Vulnerabilities on Criminal Variety: A Cross-Continental Study in Young Adults.

Previous research has shown a robust association between different childhood and adolescent vulnerabilities and youth offending. However, these investigations have primarily focused on youths from high-income Western countries. Consequently, the generalizability of these findings to better inform global justice policies remains uncertain.

Bed bug control with various dusts: Efficacy comparison between silicon dioxide, diatomaceous earth, and Sommières earth.

Bed bugs are considered a major public health problem in industrialized countries. Usually, bed bug infestations are managed using a combination of physical and chemical methods. In recent years, new strategies for bed bug control have emerged, particularly the use of dusts like diatomaceous earth and silicon dioxide.

Asymptomatic Leishmania infantum infection in dogs and dog owners in an endemic area in southeast France.

The prevalence of asymptomatic leishmaniasis in dogs and their owners in the main endemic areas of France has not been studied to date. The objective of this study was to quantify asymptomatic Leishmania infantum infection in southeast France in healthy people and their dogs using molecular and serological screening techniques. We examined the presence of parasitic DNA using specific PCR targeting kinetoplast DNA (kDNA) and specific antibodies by serology (ELISA for dogs and Western blot for humans) among immunocompetent residents and their dogs in the Alpes-Maritimes.

Adaptation and validation of the muscle dysmorphic disorder inventory in a population of French athletes (MDDI-Fr).

Introduction: Muscle dysmorphia, a theme mainly investigated by Anglo-Saxon research, is a specific body dysmorphic disorder that characterizes individuals who think they are insufficiently muscular and lean. Understudied in francophone countries, tools translated and validated in French to measure the symptomatology of muscle dysmorphia remain rare.

Objectives: The aim of this study was the translation into French and the psychometric validation of a tool evaluating muscle dysmorphia, the Muscle Dysmorphic Disorder Inventory (MDDI-Fr), through 13 items divided into three dimensions: the "Drive For Size" (DFS), the "Appearance Intolerance" (AI) and the "Functional Impairment" (FI).

Performance of five serological tests in the diagnosis of visceral and cryptic leishmaniasis: a comparative study.

Introduction: Leishmaniasis is a major health problem and its diagnosis still represents a challenge. Since consistent evidence on the comparison of serological methods is lacking, our work aims to compare five serological tests for the diagnosis of visceral and asymptomatic leishmaniasis in southern France, a region where leishmaniasis is endemic.

Methodology: Serum samples from 75 patients living in Nice, France were retrospectively analyzed.

The global impact of adverse childhood experiences on criminal behavior: A cross-continental study.

Background: Adverse Childhood Experiences (ACEs) have been associated with a greater risk of later criminal offending. However, existing research in this area has been primarily conducted in Western developed countries and cross-cultural studies are rare.

Objectives: This study examined the relationship between ACEs and criminal behaviors in young adults living in 10 countries located across five continents, after accounting for sex, age, and cross-national differences.

The C-terminal segment of Leishmania major HslU: Toward potential inhibitors of LmHslVU activity.

It is urgent to develop less toxic and more efficient treatments for leishmaniases and trypanosomiases. We explore the possibility to target the parasite mitochondrial HslVU protease, which is essential for growth and has no analogue in the human host. For this, we develop compounds potentially inhibiting the complex assembly by mimicking the C-terminal (C-ter) segment of the ATPase HslU.

New method for screening anti-Leishmania compounds in plants extracts by HPTLC-bioautography.

Leishmania genus is responsible for leishmaniasis, a group of diseases affecting 12 million people in the tropical and subtropical zone. Currently, the few drugs that are available to treat this disease are expensive and cause many side effects. Searching for new therapeutics from plant species seems to be a promising path.

Identification of adipocytes as target cells for Leishmania infantum parasites.

Leishmania infantum is the causative agent of visceral leishmaniasis transmitted by the bite of female sand flies. According to the WHO, the estimated annual incidence of leishmaniasis is one million new cases, resulting in 30,000 deaths per year. The recommended drugs for treating leishmaniasis include Amphotericin B.

A comparative study of cognitive and socio-emotional development in children with Rubinstein-Taybi syndrome and children with Autism Spectrum Disorder associated with a severe intellectual disability, and in young typically developing children with matched developmental ages.

Background: Cognitive and socio-emotional profiles of children with CREBBP-related Rubinstein-Taybi syndrome (RSTS 1), children with Autism Spectrum Disorder (ASD) with severe intellectual disability and developmental ages (DA) under 24 months, and typically developing (TD) children with similar DA were compared.

Participants: Thirty-one children with RSTS 1 (mean chronological age, CA = 59,8 months; 33-87) and thirty children with ASD, matched on CA and DA and developmental quotients (DQ), were compared to thirty TD children (CA ranged from 12 to 24 months).

Methods: Cognitive and socio-emotional developmental levels, DA and DQ were assessed with appropriated tests.

Escherichia coli Rho GTPase-activating toxin CNF1 mediates NLRP3 inflammasome activation via p21-activated kinases-1/2 during bacteraemia in mice.

Inflammasomes are signalling platforms that are assembled in response to infection or sterile inflammation by cytosolic pattern recognition receptors. The consequent inflammasome-triggered caspase-1 activation is critical for the host defence against pathogens. During infection, NLRP3, which is a pattern recognition receptor that is also known as cryopyrin, triggers the assembly of the inflammasome-activating caspase-1 through the recruitment of ASC and Nek7.

Double-task exercise programmes to strengthen cognitive and vascular health in older adults at risk of cognitive decline: protocol for a randomised clinical trial.

Introduction: Cognitive and physical declines are frequent causes of disability among older adults (OAs) in Mexico that imposes significant burden on the health system and OAs' families. Programmes to prevent or delay OAs' cognitive and physical decline are scarce.

Methods And Analysis: A double-blind randomised clinical trial will be conducted.

Emotional lability and irritability have specific associations with symptomatology in children with attention deficit hyperactivity disorder.

Irritability and emotional lability have been shown to be severity and impairment factors in community and clinical sample studies and are frequent comorbid features of Attention Deficit Hyperactivity Disorder (ADHD). However, while irritability and emotional lability seem to be closely linked, the differential effect of these two features has received little attention. This study assessed the distinct associations of irritability and emotional lability on symptomatology in children with ADHD.

The relation between ADHD symptoms, perceived stress and binge drinking in college students.

Binge drinking is a major public health problem associated with various negative short-term and long-term clinical and social outcomes. If there is evidence to suggest a relationship between ADHD and alcohol use in college students, no study has investigated the role of ADHD symptomatology in binge drinking. Thus, this research was designed to explore the relative contributions of inattention and hyperactivity/impulsivity symptoms to binge drinking in a sample of French college students while controlling for effects of perceived stress.

Association between adolescent rough-and-tumble play and conduct problems, substance use, and risk-taking behaviors: Findings from a school-based sample.

Rough-and-tumble play (RTP), also known as play fighting, is a common form of play frequently reported and studied by researchers. However, one important limitation of past research in the area of RTP has been the neglect of the adolescence period. Consequently, little is known about the function of adolescent RTP as well as about clinical characteristics of youth who engage in this activity after childhood.

Is self-esteem associated with self-rated health among French college students? A longitudinal epidemiological study: the i-Share cohort.

Objectives: The aim of the study was to estimate the association between self-esteem and subsequent self-rated health during college years, taking into account a wide range of potential confounders.

Design: Prospective longitudinal study.

Setting: The French i-Share cohort.

Adolescent Mental Health and the Choking Game.

Objectives: To examine the demographic and health risk factors associated with participation in the choking game (CG), a dangerous and potentially fatal strangulation activity in which pressure is applied to the carotid artery to temporarily limit blood flow and oxygen.

Methods: We obtained data from 2 cross-sectional studies realized respectively in 2009 and 2013 among French middle school students. The 2009 ( = 746) and 2013 ( = 1025) data sets were merged ( = 1771), and multivariate modeling was conducted to examine demographic and clinical characteristics of youth reporting a lifetime participation in the CG.

Leishmania infection: Misdiagnosis as cancer and tumor-promoting potential.

Given the prevalence of cancer and leishmaniasis worldwide, the presence of these two pathologies in the same tissue sample may be merely fortuitous. The clinical outcome of both diseases is under the control of innate and adaptive immunity, and in both cases these progressive diseases are characterized by an impaired host Th1 response. As a consequence, the Th2 cytokine microenvironment occurring in progressive leishmaniasis may potentially promote tumor cell proliferation and vice versa.

Subclinical Leishmania infection in patients with rheumatic diseases under biological drugs.

Purpose: Climate changes and immunosuppression are influencing the spread of leishmaniasis and re-emergence in Northern Italy, respectively. We evaluated the prevalence of subclinical leishmaniasis in patients from a Northern Italian region with chronic inflammatory rheumatism (CIRD) receiving biological drugs (BD) and correlated it to the area of residence.

Methods: DNA from PBMC of patients affected by CIRD treated with either BD for at least 5 years (Group A) or other immunosuppressive drugs (Group B) was investigated by a qPCR for Leishmania infantum kDNA and compared to healthy subjects (Group C).

UHPLC-HRMS/MS Based Profiling of Algerian Lichens and Their Antimicrobial Activities.

Lichens are complex symbiotic organisms able to produce a vast array of compounds. The Algerian lichen diversity has only prompted little interest even given the 1085 species listed. Herein, the chemodiversity of four Algerian lichens including Cladonia rangiformis, Ramalina farinaceae, R.

Childhood trajectories of peer victimization and prediction of mental health outcomes in midadolescence: a longitudinal population-based study.

Background: Exposure to peer victimization is relatively common. However, little is known about its developmental course and its effect on impairment associated with mental illnesses. We aimed to identify groups of children following differential trajectories of peer victimization from ages 6 to 13 years and to examine predictive associations of these trajectories with mental health in adolescence.

Calcium supplementation decreases BCP-induced inflammatory processes in blood cells through the NLRP3 inflammasome down-regulation.

Unlabelled: Interaction of host blood with biomaterials is the first event occurring after implantation in a bone defect. This study aimed at investigating the cellular and molecular consequences arising at the interface between whole blood and biphasic calcium phosphate (BCP) particles. We observed that, due to calcium capture, BCP inhibited blood coagulation, and that this inhibition was reversed by calcium supplementation.

Is emotional lability a marker for attention deficit hyperactivity disorder, anxiety and aggression symptoms in preschoolers?

Background: Emotional lability (EL) is frequent in school-aged children with attention deficit hyperactivity disorder (ADHD) and is associated with more frequent comorbidities and more severe impairment. However, little research has investigated the association between EL, ADHD and comorbid symptoms in preschoolers. This study assessed dimensional EL in preschoolers and its link with ADHD symptoms (e.

Temperament in infancy and behavioral and emotional problems at age 5.5: The EDEN mother-child cohort.

Objective: Early temperamental characteristics may influence children's developmental pathways and predict future psychopathology. However, the environmental context may also shape or interact with infant temperament and indirectly contribute to increased vulnerability to adverse developmental outcomes. The aim of the present study is to explore the long-term contribution of temperamental traits at twelve months of age to the presence of emotional and behavioral problems later in childhood, and whether this association varies with the child's sex, parental separation, family socioeconomic status and maternal depression.
