The aim of this study was to explore and identify why young adults aged between 18 and 30 years in the UK and France do or do not consume dairy products. Several studies have associated dairy products with a healthy diet, and the production of soft dairy, i.e.

Functional outcome in low-ASPECTS (0-5) acute ischemic stroke treated with mechanical thrombectomy: impact of laterality explored in a single-center study.

Background: There is no consensus regarding the influence of infarct laterality in patients with acute ischemic stroke due to anterior large vessel occlusion (AIS-LVO) treated with mechanical thrombectomy (MT), particularly in low-ASPECT (0-5) patients who were excluded from the initial MT studies and that participated in dedicated randomized-controlled trials that do not consider the side of the occlusion. We aimed to evaluate the role of infarct laterality on the clinical outcome in low-ASPECT AIS patients treated with MT.

Material And Methods: We retrospectively analyzed our institutional stroke database in our Thrombectomy-Capable Stroke Center (TCSC), including patient characteristics, procedural variables, and outcomes, between January 2015 and January 2022.

On the Hedging of Interest Rate Margins on Bank Demand Deposits.

In recent years, we have seen a very rapid increase in outstanding bank deposits. This increase has been particularly high since the outbreak of the COVID 19 pandemic, due to the lockdown that has, among other things, drastically reduced household consumption since the beginning of March 2020. This very sharp increase in outstandings increases the risk of banks which offer interest on deposits.

HIV-1 Envelope Recognition by Polyreactive and Cross-Reactive Intestinal B Cells.

Mucosal immune responses to HIV-1 involve the recognition of the viral envelope glycoprotein (gp)160 by tissue-resident B cells and subsequent secretion of antibodies. To characterize the B cells "sensing" HIV-1 in the gut of infected individuals, we probed monoclonal antibodies produced from single intestinal B cells binding to recombinant gp140 trimers. A large fraction of mucosal B cell antibodies were polyreactive and showed only low affinity to HIV-1 envelope glycoproteins, particularly the gp41 moiety.

Conformational Plasticity in Broadly Neutralizing HIV-1 Antibodies Triggers Polyreactivity.

Human high-affinity antibodies to pathogens often recognize unrelated ligands. The molecular origin and the role of this polyreactivity are largely unknown. Here, we report that HIV-1 broadly neutralizing antibodies (bNAbs) are frequently polyreactive, cross-reacting with non-HIV-1 molecules, including self-antigens.

Should We Screen for Janus Kinase 2 V617F Mutation in Cerebral Venous Thrombosis?

Background: The presence of Janus Kinase 2 (JAK2) V617F mutation represents a major diagnostic criterion for detecting myeloproliferative neoplasms (MPN) and even in the absence of overt MPN, JAK2 V617F mutation is associated with splanchnic vein thrombosis. However, the actual prevalence and diagnostic value of the JAK2 V617F mutation in patients with cerebral venous thrombosis (CVT) are not known. The aims of this study were to assess the prevalence of JAK2 V617F mutation in a large group of consecutive CVT patients, to detect clinical, biological, and radiological features associated with the mutation, and to determine the long-term venous thrombosis recurrence rate in CVT patients with JAK2 mutation but without overt MPN in order to recommend the best preventive treatment.

Adult-Derived Human Liver Stem/Progenitor Cells Infused 3 Days Postsurgery Improve Liver Regeneration in a Mouse Model of Extended Hepatectomy.

There is growing evidence that cell therapy constitutes a promising strategy for liver regenerative medicine. In the setting of hepatic cancer treatments, cell therapy could prove a useful therapeutic approach for managing the acute liver failure that occurs following extended hepatectomy. In this study, we examined the influence of delivering adult-derived human liver stem/progenitor cells (ADHLSCs) at two different early time points in an immunodeficient mouse model (Rag2-/-IL2Rγ-/-) that had undergone a 70% hepatectomy procedure.

Scarcity of autoreactive human blood IgA memory B cells.

Class-switched memory B cells are key components of the "reactive" humoral immunity, which ensures a fast and massive secretion of high-affinity antigen-specific antibodies upon antigenic challenge. In humans, IgA class-switched (IgA ) memory B cells and IgA antibodies are abundant in the blood. Although circulating IgA memory B cells and their corresponding secreted immunoglobulins likely possess major protective and/or regulatory immune roles, little is known about their specificity and function.

Human Progenitor Cell Quantification After Xenotransplantation in Rat and Mouse Models by a Sensitive qPCR Assay.

Xenotransplantation of human cells in animal models is an essential tool for evaluation of safety and efficacy of cell-based products for therapeutic use. Sensitive and reproducible methods are needed to detect and quantify human cells engrafted into the host tissue either in the targeted organ or in undesired locations. We developed a robust quantitative polymerase chain reaction (qPCR) assay based on amplification of human AluYb8 repeats, to assess the number of human cells present in rat or mouse tissues after transplantation.

Human Liver Progenitor Cells for Liver Repair.

Because of their high proliferative capacity, resistance to cryopreservation, and ability to differentiate into hepatocyte-like cells, stem and progenitor cells have recently emerged as attractive cell sources for liver cell therapy, a technique used as an alternative to orthotopic liver transplantation in the treatment of various hepatic ailments ranging from metabolic disorders to end-stage liver disease. Although stem and progenitor cells have been isolated from various tissues, obtaining them from the liver could be an advantage for the treatment of hepatic disorders. However, the techniques available to isolate these stem/progenitor cells are numerous and give rise to cell populations with different morphological and functional characteristics.

Neutralising antibodies against ricin toxin.

The Centers for Disease Control and Prevention have listed the potential bioweapon ricin as a Category B Agent. Ricin is a so-called A/B toxin produced by plants and is one of the deadliest molecules known. It is easy to prepare and no curative treatment is available.

Production and characterisation of a neutralising chimeric antibody against botulinum neurotoxin A.

Botulinum neurotoxins, produced by Clostridium botulinum bacteria, are the causative agent of botulism. This disease only affects a few hundred people each year, thus ranking it among the orphan diseases. However, botulinum toxin type A (BoNT/A) is the most potent toxin known to man.

The stringent response of Bacillus anthracis contributes to sporulation but not to virulence.

The Gram-positive, spore-forming pathogen Bacillus anthracis is the aetiological agent of anthrax. Its main virulence factors are two toxins and an anti-phagocytic capsule. When B.

In situ gynogenetic haploid plants of chicory (Cichorium intybus L.) after intergeneric hybridization with Cicerbita alpina Walbr.

The possibility of obtaining haploid plants of chicory (Cichorium intybus L.) was investigated through intergeneric hybridization. Chicory plants (industrial chicory and Chioggia) were pollinated with pollen of Lactuca tatarica L.

Use of oxygen uptake recovery curve to predict peak oxygen uptake in upper body exercise.

A group of 18 well-trained white-water kayakers performed maximal upper body exercise in the laboratory and during a field test. Laboratory direct peak oxygen uptake (VO2) values were compared, firstly by a VO2 backward extrapolation estimation and secondly by an estimation calculated from VO2 measured during the first 20 s of exercise recovery. Direct peak VO2 correlated with VO2 backward extrapolation (r = 0.

[Incest by the mother: clinical and therapeutic aspects].

Whereas clinical and preventive aspects of father-daughter incest are now better-known, mother-child incest remains mysterious. Reporting four recent cases, the authors attempt to describe its main clinical features, particularly those which could allow earlier diagnosis. An original "constructive" therapeutic approach of the most severely mentally disturbed children among these victims is then developed: the emphasis is put on how medical, social and legal procedures might be coordinated.

[Reactive arthritis caused by Yersinia in children. Report of 4 cases].

Among a group of children hospitalized for "joint pain", four of the cases of reactive arthritis were due to Yersinia infection. These four cases are described. Some patients had suggestive clinical symptoms but serologic studies were needed to establish the diagnosis.

[Mycobacterium chelonei pulmonary infections. Apropos of a case].

Infections caused by Mycobacterium chelonei are rare. We report a case of pulmonary infection in a 57-year-old non-immunocompromised woman. Most of the abnormalities were observed at radiology which showed bilateral apical excavated opacities.

A method of comparing spermatozoa with light and scanning electron microscopy.

A new method of comparing light microscopy and scanning electron microscopy in the study of small cells, such as spermatozoa, that must be examined under oil immersion is described. A grid is etched on the corner of a microscope glass slide, and its inner edges are incised. Its surface area is calculated as a function f the chamber of the critical-point drying apparatus.
