Our study explores the complex dynamics of the integrated stress response (ISR) axis, highlighting PIM2 kinase's critical role and its interaction with the BCL2 protein family, uncovering key mechanisms of cell survival and tumor progression. Elevated PIM2 expression, a marker of various cancers, often correlates with disease aggressiveness. Using a model of normal and malignant plasma cells, we show that inhibiting PIM2 kinase inhibits phosphorylated BAD production and activates ISR-mediated NOXA expression.

Interest and limits of using pharmacogenetics in MDMA-related fatalities: A case report.

Forensic Sci Int Genet

December 2024

Service de Pharmacologie-Toxicologie et Pharmacovigilance, Centre Hospitalo-Universitaire d'Angers, Angers, France.

Interpreting postmortem concentrations of 3,4-Methylenedioxymethamphetamine (MDMA) remains challenging due to the wide range of reported results and the potential idiosyncratic nature of MDMA toxicity. Consequently, forensic pathologists often rely on a body of evidence to establish conclusions regarding the cause and the manner of death in death involving MDMA. Given these issues, implementing pharmacogenetics' (PGx)' testing may be beneficial.

To assess the accuracy of Kidney Stone Calculator(KSC), a software designed for surgical planning, in predicting the duration of lithotripsy during flexible ureteroscopy(FURS) when using the novel pulsed-Thulium: YAG(p-Tm: YAG) laser. From February to August 2023, a single-center prospective study was conducted, including patients with kidney or ureteral stones through non-contrast computed tomography(NCCT), who underwent FURS with p-Tm: YAG laser lithotripsy. KSC used three-dimensional segmentation of the stones from NCCT images, along with an interactive user interface for laser settings, to estimate the stone volume(SV) and the lithotripsy duration(LD).

Aims: Mycophenolic acid (MPA), the active component of enteric-coated mycophenolate sodium (EC-MPS), exhibits highly variable pharmacokinetics. Only a few population pharmacokinetic (popPK) models and Bayesian estimators (MAP-BE) exist for estimating MPA AUC and all in renal transplantation. This study aimed to develop a popPK model and MAP-BE for MPA AUC estimation using a limited sampling strategy (LSS) in solid organ transplant (SOT), haematopoietic stem cell (HSC) recipients and patients with autoimmune diseases (AID) on EC-MPS.

Background: Hansen's disease is an infectious disease with a slow and chronic evolution that can manifest itself through skin lesions, with changes in thermal, painful and tactile sensitivity, and also affect peripheral nerves, causing significant physical disabilities. This study aimed to analyze the meanings and senses for health workers from outpatient services who provide care to people diagnosed with Hansen's disease.

Methods: This is an exploratory qualitative study that used the Vygotskian theoretical-methodological framework based on the dimension of historical-dialectic materialism that bases its procedures on the use of meaning cores.

Article Synopsis
  • * Quick diagnosis and treatment of kidney problems in these patients are crucial, with therapies focusing on hydration, correcting contributing factors, and administering effective anti-myeloma drugs while considering the patient's kidney function and overall health.
  • * Advanced treatments like plasma exchange may improve kidney recovery in severe cases, and newer combinations of medications show promise, with the possibility of kidney transplantation for some patients in the future.

Renal manifestations of MGUS.

Hematology Am Soc Hematol Educ Program

December 2024

Department of Hematology and Cellular Therapy, Centre de référence maladies rares, Amylose AL et autres maladies par dépôts d'immunoglobulines monoclonales, Centre Hospitalier Universitaire Limoges, Université de Limoges, Limoges, France.

Kidney disease is a common complication of monoclonal immunoglobulin (MIg)-secreting B-cell disorders and predominantly occurs in patients who do not meet the criteria for an overt hematological disease. To distinguish this situation from monoclonal gammopathy of undetermined significance, which lacks organ damage, the term monoclonal gammopathy of renal significance (MGRS) was introduced to depict the association of a small, otherwise indolent B-cell clone, with renal disease induced by the secreted MIg. The spectrum of renal disorders in MGRS is wide, encompassing both tubular and glomerular disorders, classified according to the composition of deposits and their ultrastructural pattern of organization.

Lichen and Its Microbiome as an Untapped Source of Anti-Biofilm Compounds.

Chem Biodivers

November 2024

Laboratoire des Agroressources, Biomolécules et Chimie pour l'Innovation en Santé (LABCiS), UR 22722, Université de Limoges, Limoges, France.

Lichen substances have been first described in the 1870s, and around 10 000 compounds have been isolated and characterized. Most of them have been evaluated for their activity on planktonic microorganisms (bacteria and fungi). More recently, microorganisms colonizing the lichen thallus have been isolated and identified using DNA sequencing, giving access to a wide diversity of culturable microorganisms.

Article Synopsis
  • * Its overexpression is particularly linked to CLL cases with unmutated immunoglobulin heavy chain variable (IGHV) genes, causing significant DNA damage and contributing to a more aggressive disease.
  • * The review emphasizes c-MYC's dual role in promoting rapid cell proliferation and driving genetic recombination, suggesting it could be a promising target for new therapeutic strategies in CLL.

French-Speaking Network of Pharmacogenetics (RNPGx) Recommendations for Clinical Use of Mavacamten.

Clin Pharmacol Ther

November 2024

Laboratoire de Pharmacologie et Toxicologie NeuroCardiovasculaire, UR7296, Hopitaux Universitaires de Strasbourg, Université de Strasbourg, Strasbourg, France.

Mavacamten, the first drug in the class of β-cardiac myosin modulator, is used for the treatment of patients with hypertrophic cardiomyopathy. This orally administered drug demonstrates wide interpatient variability in pharmacokinetics parameters, due in part to variant CYP2C19 alleles. Individuals who are CYP2C19 poor metabolizers have increased exposure and are at increased risk of reduced cardiac hypercontractility.

We present a 2.5-mm-diameter resonant fiber scanning two-photon microendoscope with a 30-mm long forward-viewing rigid probe tip that enables video-rate imaging (20 Hz frame rate) suitable for hand-held imaging of tissues without motion artifacts. Higher-order harmonic oscillation scanning techniques are developed to significantly increase the frame rate compared to prior published fiber scanning microendoscopy designs while maintaining the field-of-view (∼125 µm), the optical resolution (1.

Article Synopsis
  • The purpose of this project was to update the 2016 recommendations regarding the management of immunosuppressants or biologics in patients with giant cell arteritis (GCA).
  • A task force of 18 physicians developed 26 validated recommendations after thorough discussion and a >85% consensus process.
  • Key recommendations include using subcutaneous tocilizumab (TCZ) as a first-line treatment when glucocorticoid-sparing is needed, initiating TCZ at diagnosis for patients with specific high-risk conditions, and considering TCZ or methotrexate if glucocorticoid discontinuation is not feasible after 12 months.

[Challenges and advances in the management of HCMV infections].

Virologie (Montrouge)

October 2024

Institut toulousain des Maladies infectieuses et inflammatoires (Infinity), Université de Toulouse, Inserm, CNRS, UPS, Toulouse, France.

Human cytomegalovirus (HCMV) is one of the most important causes of complications in immunocompromised patients and congenital infections. HCMV could also represent an interesting target for treatment to limit the progression of glioblastoma, a highly aggressive tumor. Ganciclovir, foscarnet and cidofovir, which interfere with the activity of the viral polymerase pUL54, are widely used in the treatment of transplant patients.

Bending rigidity, k, is classically measured for lipid membranes to characterize their nanoscale mechanical properties as a function of composition. Widely employed as a comparative tool, it helps understanding the relationship between the lipid's molecular structure and the elastic properties of its corresponding bilayer. Widely measured for phospholipid membranes in the shape of giant unilamellar vesicles (GUVs), bending rigidity is determined here for three self-assembled structures formed by a new biobased glucolipid bioamphiphile, rather associated to the family of glycolipid biosurfactants than phospholipids.
