Corneal Stromal Stem Cell-Derived Extracellular Vesicles Attenuate ANGPTL7 Expression in the Human Trabecular Meshwork.

Purpose: Regulating intraocular pressure (IOP), mainly via the trabecular meshwork (TM), is critical in developing glaucoma. Whereas current treatments aim to lower IOP, directly targeting the dysfunctional TM tissue for therapeutic intervention has proven challenging. In our study, we utilized Dexamethasone (Dex)-treated TM cells as a model to investigate how extracellular vesicles (EVs) from immortalized corneal stromal stem cells (imCSSCs) could influence ANGPTL7 and MYOC genes expression within TM cells.

Diagnostic impact of DNA methylation classification in adult and pediatric CNS tumors.

Over the past decade, neuropathological diagnosis has undergone significant changes, integrating morphological features with molecular biomarkers. The molecular era has successfully refined neuropathological diagnostic accuracy; however, a substantial number of CNS tumor diagnoses remain challenging, particularly in children. DNA methylation classification has emerged as a powerful machine learning approach for clinical decision-making in CNS tumors.

Isatuximab, Carfilzomib, Lenalidomide, and Dexamethasone Induction in Newly Diagnosed Myeloma: Analysis of the MIDAS Trial.

In patients with transplant-eligible newly diagnosed multiple myeloma, induction therapy with a quadruplet regimen prior to autologous transplant is the standard of care. The phase III IFM2020-02-MIDAS study (NCT04934475) assessed a minimal residual disease (MRD)-driven consolidation and maintenance strategy following induction with isatuximab, carfilzomib, lenalidomide, and dexamethasone (IsaKRD). Here, we report safety and efficacy outcomes of six 28-day cycles of IsaKRD.

Long legs and small joints: The locomotor capabilities of Homo naledi.

The lower limb of Homo naledi presents a suite of primitive, derived and unique morphological features that pose interesting questions about the nature of bipedal movement in this species. The exceptional representation of all skeletal elements in H. naledi makes it an excellent candidate for biomechanical analysis of gait dynamics using modern kinematic software.

Investigating the Spatio-Temporal Signatures of Language Control-Related Brain Synchronization Processes.

Language control processes allow for the flexible manipulation and access to context-appropriate verbal representations. Functional magnetic resonance imaging (fMRI) studies have localized the brain regions involved in language control processes usually by comparing high vs. low lexical-semantic control conditions during verbal tasks.

Antiphospholipid antibodies positivity as a potential risk factor for restenosis following arteriovenous fistula stenting in hemodialysis patients: a pilot study.

Background: The arteriovenous fistula (AVF) is the preferred vascular access for hemodialysis. AVF stenosis is a common complication, often requiring balloon angioplasty. For recurrent stenosis, AVF stenting may be an option.

Efficient optimisation of physical reservoir computers using only a delayed input.

Reservoir computing is a machine learning algorithm for processing time dependent data which is well suited for experimental implementation. Tuning the hyperparameters of the reservoir is a time-consuming task that limits is applicability. Here we present an experimental validation of a recently proposed optimisation technique in which the reservoir receives both the input signal and a delayed version of the input signal.

Fine-tuning of gene expression through the Mettl3-Mettl14-Dnmt1 axis controls ESC differentiation.

The marking of DNA, histones, and RNA is central to gene expression regulation in development and disease. Recent evidence links N6-methyladenosine (mA), installed on RNA by the METTL3-METTL14 methyltransferase complex, to histone modifications, but the link between mA and DNA methylation remains scarcely explored. This study shows that METTL3-METTL14 recruits the DNA methyltransferase DNMT1 to chromatin for gene-body methylation.

Extracellular vesicles from chronic lymphocytic leukemia cells promote leukemia aggressiveness by inducing the differentiation of monocytes into nurse-like cells via an RNA-dependent mechanism.

Chronic lymphocytic leukemia (CLL) cells receive several stimuli from surrounding cells, such as B-cell receptor (BCR) stimulation, and can manipulate their microenvironment via extracellular vesicle (EV) release. Here, we investigated the small RNA content (microRNA and YRNA) of CLL-EVs from leukemic cells cultured with/without BCR stimulation. We highlight an increase of miR-155-5p, miR-146a-5p, and miR-132-3p in EVs and in cells after BCR stimulation ( < 0.

Mechanisms of Regulation of Cell Fate in Breast Development and Cancer.

This chapter focuses on the mechanisms of regulation of cell fate in breast development, occurring mainly after birth, as well as in breast cancer. First, we will review how the microenvironment of the breast, as well as external cues, plays a crucial role in mammary gland cell specification and will describe how it has been shown to reprogram non-mammary cells into mammary epithelial cells. Then we will focus on the transcription factors and master regulators which have been established to be determinant for basal (BC) and luminal cell (LC) identity, and will describe the experiments of ectopic expression or loss of function of these transcription factors which demonstrated that they were crucial for cell fate.

Trauma exposure as a risk factor of major depressive disorder: A matched case-control study.

The association between childhood trauma (CT), stressful life events (SLE) and the onset and severity of major depressive disorder (MDD) has not been extensively studied. This study aimed to investigate the separate and combined association of CT and SLE with the onset and severity of MDD. A total of 503 patients with MDD and 503 controls were included.

Percutaneous treatment of de Quervain's disease using Sono-Instruments®: A feasibility study.

Changes in Muscle Quality Following Short-Term Resistance Training in Older Adults: A Comparison of Echo Intensity and Texture Analysis.

Background: Skeletal muscle echo intensity (EI) is associated with functional outcomes in older adults, but resistance training interventions have shown mixed results. Texture analysis has been proposed as a novel approach for assessing muscle quality, as it captures spatial relationships between pixels. It is unclear whether texture analysis is able to track changes following resistance training.

When the mask slips: A peripheral T-cell lymphoma disguised as lupus with myelofibrosis in a patient with May-Hegglin syndrome.

We describe the case of a female patient with May-Hegglin syndrome who developed peripheral T-cell lymphoma not otherwise specified. The patient presents with systemic lupus erythematous phenotype and myelofibrosis secondary to T-cell lymphoma. Peripheral T-cell lymphoma not otherwise specified, represents 25 % of all peripheral T-cell lymphoma.

Adaptive evolution of stress response genes in parasites aligns with host niche diversity.

Background: Stress responses are key the survival of parasites and, consequently, also the evolutionary success of these organisms. Despite this importance, our understanding of the evolution of molecular pathways dealing with environmental stressors in parasitic animals remains limited. Here, we tested the link between adaptive evolution of parasite stress response genes and their ecological diversity and species richness.

Shaping the structural dynamics of motor learning through cueing during sleep.

Enhancing the retention of recent memory traces through sleep reactivation is possible via Targeted Memory Reactivation (TMR), involving cueing learned material during post-training sleep. Evidence indicates detectable short-term microstructural changes in the brain within an hour after motor sequence learning, and post-training sleep is believed to contribute to the consolidation of these motor memories, potentially leading to enduring microstructural changes. In this study, we explored how TMR during post-training sleep affects performance gains and delayed microstructural remodeling, using both standard Diffusion Tensor Imaging (DTI) and advanced Neurite Orientation Dispersion & Density Imaging (NODDI).

Strategies to Overcome Intrinsic and Acquired Resistance to Chemoradiotherapy in Head and Neck Cancer.

Definitive chemoradiotherapy (CRT) is a cornerstone of treatment for locoregionally advanced head and neck cancer (HNC). Research is ongoing on how to improve the tumor response to treatment and limit normal tissue toxicity. A major limitation in that regard is the growing occurrence of intrinsic or acquired treatment resistance in advanced cases.

From Knowledge to Practice: Design, Implementation, and Evaluation of an Evidence-Based Educational Module to Increase Cultural Awareness in Nursing Students.

Educational programs for health-care providers increasingly implement culturally sensitive care. Clear methods for educating students in cultural awareness are still lacking. Research indicates that simply increasing knowledge on ethnicity, culture, or migration does not improve culturally sensitive behavior and can foster stereotypes.

Solid-phase red cell adherence versus gel column agglutination: Is there any difference for the detection of alloantibodies associated with the JK system?

Background: Detection of alloantibodies associated with the JK system may be tricky. They are nevertheless associated with transfusion reactions and their detection is crucial.

Charge-transfer complexation of coordination cages for enhanced photochromism and photocatalysis.

Intensified host-guest electronic interplay within stable metal-organic cages (MOCs) presents great opportunities for applications in stimuli response and photocatalysis. Zr-MOCs represent a type of robust discrete hosts for such a design, but their host-guest chemistry in solution is hampered by the limited solubility. Here, by using pyridinium-derived cationic ligands with tetrakis(3,5-bis(trifluoromethyl)phenyl)borate (BAr) as solubilizing counteranions, we report the preparation of soluble Zr-MOCs of different shapes (1-4) that are otherwise inaccessible through a conventional method.

Astaxanthin-loaded PLGA nanoparticles inhibit survival of MKN-45 gastric cancer cell line by modulating JAK2/STAT3/mTOR/PI3K pathway.

Background/aims: Gastric cancer (GC) is a significant global health issue with high incidence rates and poor prognoses, ranking among the top prevalent cancers worldwide. Due to undesirable side effects and drug resistance, there is a pressing need for the development of novel therapeutic strategies. Understanding the interconnectedness of the JAK2/STAT3/mTOR/PI3K pathway in tumorigenesis and the role of Astaxanthin (ASX), a red ketocarotenoid member of xanthophylls and potent antioxidant and anti-tumor activity, can be effective for cancer treatments.
