Characteristic repartition of monocyte subsets as a diagnostic signature of chronic myelomonocytic leukemia.

Chronic myelomonocytic leukemia (CMML) is a myelodysplastic syndrome/ myeloproliferative neoplasm whose diagnosis is currently based on the elevation of peripheral blood monocytes to >1 × 10(9)/L, measured for ≥3 months. Diagnosis can be ambiguous; for example, with prefibrotic myelofibrosis or reactive monocytosis. We set up a multiparameter flow cytometry assay to distinguish CD14(+)/CD16(-) classical from CD14(+)/CD16(+) intermediate and CD14(low)/CD16(+) nonclassical monocyte subsets in peripheral blood mononucleated cells and in total blood samples.

The lung mycobiome: an emerging field of the human respiratory microbiome.

The lung microbiome, which is believed to be stable or at least transient in healthy people, is now considered as a poly-microorganism component contributing to disease pathogenesis. Most research studies on the respiratory microbiome have focused on bacteria and their impact on lung health, but there is evidence that other non-bacterial organisms, comprising the viruses (virome) and fungi (mycobiome), are also likely to play an important role in healthy people as well as in patients. In the last few years, the lung mycobiome (previously named the fungal microbiota or microbiome) has drawn closer attention.

In Vitro Assessment of Interaction Between Amino Acids and Copper in Neonatal Parenteral Nutrition.

Background: The repeated blackening of in-line filters has been observed during the infusion of parenteral nutrition 2-in-1 mixtures (binary parenteral nutrition [BPN]) delivered in a neonatal intensive care unit. This study aimed to examine the elemental content of precipitates isolated from infused BPN bags and determine the main physicochemical interactions occurring in these bags.

Materials And Methods: The infusion of BPN mixtures was simulated in vitro following hospital practices.

High-Grade Toxicity to Neoadjuvant Treatment for Upper Gastrointestinal Carcinomas: What is the Impact on Perioperative and Oncologic Outcomes?

Background: Perioperative oncologic treatments provide a survival benefit for junctional and gastric adenocarcinoma (JGA) and esophageal cancer (EC). Whether neoadjuvant therapy toxicity (NTT) correlates with increased perioperative risk remains unclear. We aimed to evaluate the impact of grade III/IV NTT on postoperative and oncologic outcomes in resected upper gastrointestinal malignancies.

Structured illumination microscopy and correlative microscopy to study autophagy.

Autophagy is a predominant eukaryotic mechanism for the engulfment of "portions" of cytoplasm allowing their degradation to recycle metabolites. The autophagy is ubiquitous among the life kingdom revealing the importance of this pathway that appears more complex than previously thought. Several reviews have already addressed how to monitor this pathway and have highlighted the existence of new routes such as the LC3-associated phagocytosis (LAP) and the non-canonical autophagy.

A case of respiratory depression in a child with ultrarapid CYP2D6 metabolism after tramadol.

We discuss a case of severe respiratory depression in a child, with ultrarapid CYP2D6 genotype and obstructive sleep apnea syndrome, after taking tramadol for pain relief related to a day-case tonsillectomy.

Characterization of hepatitis C virus interaction with heparan sulfate proteoglycans.

Unlabelled: Hepatitis C virus (HCV) entry involves binding to cell surface heparan sulfate (HS) structures. However, due to the lipoprotein-like structure of HCV, the exact contribution of virion components to this interaction remains controversial. Here, we investigated the relative contribution of HCV envelope proteins and apolipoprotein E in the HS-binding step.

Association between Cardiovascular Drugs and Chronic Kidney Disease in Non-Institutionalized Elderly Patients.

Concern about the renal safety of commonly used cardiovascular drugs with demonstrated clinical benefit appears to be an obstacle to their use in the elderly. The objective was to describe the relationship between cardiovascular drugs and chronic kidney disease (CKD) in elderly individuals in the real-life setting. This is an ancillary study of the prospective non-interventional S.

For your eyes only: effect of confederate's eye level on reach-to-grasp action.

Previous studies have shown that the spatio-temporal parameters of reach-to-grasp movement are influenced by the social context in which the motor action is performed. In particular, when interacting with a confederate, movements are slower, with longer initiation times and more ample trajectories, which has been interpreted as implicit communicative information emerging through voluntary movement to catch the partner's attention and optimize cooperation (Quesque et al., 2013).

The influence of 1-butanol and trisodium citrate ion on morphology and chemical properties of chitosan-based microcapsules during rigidification by alkali treatment.

Linseed oil which has various biomedical applications was encapsulated by chitosan (Chi)-based microcapsules in the development of a suitable carrier. Oil droplets formed in oil-in-water emulsion using sodium dodecyl sulfate (SDS) as emulsifier was stabilized by Chi, and microcapsules with multilayers were formed by alternate additions of SDS and Chi solutions in an emulsion through electrostatic interaction. No chemical cross-linker was used in the study and the multilayer shell membrane was formed by ionic gelation using Chi and SDS.

In vitro discrimination of the role of LRP1 at the BBB cellular level: focus on brain capillary endothelial cells and brain pericytes.

Several studies have demonstrated that the blood-brain barrier (BBB) (dynamic cellular complex composed by brain capillary endothelial cells (BCECs) and surrounded by astrocytic end feet and pericytes) regulates the exchanges of amyloid β (Aβ) peptide between the blood and the brain. Deregulation of these exchanges seems to be a key trigger for the brain accumulation of Aβ peptide observed in Alzheimer's disease (AD). Whereas the involvement of receptor for advanced glycation end-products in Aβ peptide transcytosis has been demonstrated in our laboratory, low-density lipoprotein receptor's role at the cellular level needs to be clarified.

Valence-space compatibility effects depend on situated motor fluency in both right- and left-handers.

According to the body specificity hypothesis, the way we interact with our environment participates in our conceptualization of concepts and word meanings. For instance, valence is associated to horizontal space because of the motor fluency by which one acts with one's dominant hand. We propose that the decisive factor in the compatibility effects between valence and lateral actions is the interaction between the fluency of response movement and the situational constraints of the task.

Translocation path of a substrate protein through its Omp85 transporter.

TpsB proteins are Omp85 superfamily members that mediate protein translocation across the outer membrane of Gram-negative bacteria. Omp85 transporters are composed of N-terminal POTRA domains and a C-terminal transmembrane β-barrel. In this work, we track the in vivo secretion path of the Bordetella pertussis filamentous haemagglutinin (FHA), the substrate of the model TpsB transporter FhaC, using site-specific crosslinking.

Prospective genotyping of Mycobacterium tuberculosis from fresh clinical samples.

Shorter time-to-result is key for improving molecular-guided epidemiological investigation of tuberculosis (TB) cases. We performed a prospective study to evaluate the use of standardized MIRU-VNTR (mycobacterial interspersed repetitive-unit-variable-number tandem-repeat) typing of Mycobacterium tuberculosis directly on 79 fresh clinical samples from 26 TB patients consecutively enrolled over a 17-month period. Overall, complete 24-locus types were obtained for 18 out of the 26 (69.

Influence of dentist experience with scan spray systems used in direct CAD/CAM impressions.

Statement Of Problem: Direct optical impression systems requiring powder opacification are widely used in prosthodontics, but little information is available about the influence of the dentist on the quality of scan sprays used for computer-aided design and computer-aided manufacturing (CAD/CAM) impressions.

Purpose: The purpose of this study was to evaluate the influence of operator experience on scan spray homogeneity and thickness on tooth surfaces before direct optical impressions are made.

Material And Methods: A total of 36 crown-prepared acrylic resin teeth were coated (Optispray) for direct optical impressions by 3 experienced dentists and 3 inexperienced dentists (n=18 teeth per group).

Weight loss independent association of TCF7 L2 gene polymorphism with fasting blood glucose after Roux-en-Y gastric bypass in type 2 diabetic patients.

Background: Roux-en-Y gastric bypass (RYGB) surgery improves glucose control in most but not all patients with type 2 diabetes mellitus (T2 DM). Transcription factor 7-like 2 (TCF7 L2) gene variation (rs7903146, C: wild-type allele, T: risk-allele) is the strongest contributor to T2 DM risk. Until now, there are no studies investigating gene interactions with changes of glycemia in obese patients with T2 DM after RYGB.

Adverse drug events with hyperkalaemia during inpatient stays: evaluation of an automated method for retrospective detection in hospital databases.

Introduction: This report describes the first case, to the best of our knowledge, of pacemaker-induced endocarditis due to .

Presentation: Pacemaker-induced endocarditis due to infection was determined in a 92-year old man. This Gram-positive bacillus failed to be identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry technology, whereas the taxon was indexed in the database.

TRPV6 calcium channel translocates to the plasma membrane via Orai1-mediated mechanism and controls cancer cell survival.

Transient receptor potential vanilloid subfamily member 6 (TRPV6) is a highly selective calcium channel that has been considered as a part of store-operated calcium entry (SOCE). Despite its first discovery in the early 2000s, the role of this channel in prostate cancer (PCa) remained, until now, obscure. Here we show that TRPV6 mediates calcium entry, which is highly increased in PCa due to the remodeling mechanism involving the translocation of the TRPV6 channel to the plasma membrane via the Orai1/TRPC1-mediated Ca(2+)/Annexin I/S100A11 pathway, partially contributing to SOCE.

Primary care management of non-institutionalized elderly diabetic patients: The S.AGES cohort - Baseline data.

Aim: S.AGES is a multicenter prospective cohort study of non-institutionalized patients aged 65 and over with atrial fibrillation, type 2 diabetes or chronic pain. Its objective is to describe the medical management in primary care.

Role of VAMP3 and VAMP7 in the commitment of Yersinia pseudotuberculosis to LC3-associated pathways involving single- or double-membrane vacuoles.

Yersinia pseudotuberculosis can replicate inside macrophages by hijacking autophagy and blocking autophagosome acidification. In bone marrow-derived macrophages, the bacteria are mainly observed inside double-membrane vacuoles positive for LC3, a hallmark of autophagy. Here, we address the question of the membrane traffic during internalization of Yersinia investigating the role of vesicle- associated membrane proteins (VAMPs).
