High-Resolution Imaging of Spindle Orientation Dynamics in 3D Intestinal Organoids.

Live imaging of microtubules (MTs) allows obtaining mechanistic insights into cell division. In literature, mitotic spindle dynamics have been investigated in mammalian systems largely focusing on established cell lines. Here, we describe a detailed protocol that investigates MT dynamics during cell division in a 3D mouse intestinal organoid model that more accurately captures the in vivo system.

Global trends of secondhand smoke exposure among young adolescents from 27 countries, 2003-2021: findings from the World Health Organization database.

The issue of adolescent secondhand smoke (SHS) is globally significant, given that it serves as a preventable risk factor for disease prevalence and mortality rates among youth. This study evaluates trends in adolescent SHS across 27 countries from 2003 to 2021, aiming to identify global variations and sex-specific differences, providing insights for future policy recommendations. The data for this study were collected from the Global School-based Student Health Survey conducted by the World Health Organization, 2003-2021.

Stomatal opening under high temperatures is controlled by the OST1-regulated TOT3-AHA1 module.

Plants continuously respond to changing environmental conditions to prevent damage and maintain optimal performance. To regulate gas exchange with the environment and to control abiotic stress relief, plants have pores in their leaf epidermis, called stomata. Multiple environmental signals affect the opening and closing of these stomata.

Long-term outcomes among patients who respond within the first year to nivolumab plus ipilimumab or nivolumab monotherapy: A pooled analysis in 935 patients.

Purpose: To investigate the predictive value of RECIST response within 3, 6, or 12 months on long-term survival, and explore differences between nivolumab+ipilimumab and nivolumab monotherapy, we analyzed pooled 5-year data of 935 responder and non-responder patients at various time points after treatment initiation in CheckMate 069, 066, and 067 studies.

Patients And Methods: Treatment-naive advanced melanoma patients received nivolumab+ipilimumab or nivolumab monotherapy. To decrease immortal time bias, 3-, 6-, or 12-month overall survival (OS) and progression-free survival (PFS) landmark analyses were performed.

Rapid diagnosis of tuberculosis by PCR IS6110 from blood in the central region of Tunisia.

Tuberculosis remains one of the leading causes of mortality worldwide. Microscopy and culture still the references of Tuberculosis diagnosis. Microscopy has a low sensitivity, specificity and culture is time consuming.

Rossby waves driven by the Mid Mediterranean Jet impact the Eastern Mediterranean mesoscale dynamics.

The most prominent and persistent feature of the eastern Mediterranean Levantine Basin (LB) is the warm anticyclonic Cyprus Eddy (CE) located above the Eratosthenes Seamount (ESM). This eddy periodically couples with two smaller cyclonic and anticyclonic eddies, the South Shikmona Eddy (SSE) and North Shikmona Eddy (NSE), which form downstream. The reason for the zonal drift of the CE center and the formation mechanism of the CE, SSE and NSE is largely debated today, yet the upwelling and biological productivity of the LB can be strongly impacted by the local dynamics.

Patients' psychosocial attributes and aggressiveness of cancer treatments near the end of life.

Background: While the use of chemotherapy near the end of life (EOL) has been identified as a relevant criterion for assessing quality of cancer care and has been estimated as non-beneficial, a trend of aggressiveness in cancer care during the last period of life remains. Both patients' sociodemographic characteristics and physicians' practice setting are associated with this use. The role of patients' psychosocial characteristics has however been understudied.

Real-life experience with disease-modifying drugs in hereditary transthyretin amyloid polyneuropathy: A clinical and electrophysiological appraisal.

Introduction: New treatments have dramatically improved the prognosis for Hereditary Transthyretin Amyloid Polyneuropathy (ATTRv-PN). However, there is a lack of routine follow-up studies outside of therapeutic trials. Our aim was to report the long-term clinical and electrophysiological evolution of a cohort of ATTRv-PN patients and to determine which biomarkers are most sensitive to change.

International Consensus Statement on Platelet Function and Genetic Testing in Percutaneous Coronary Intervention: 2024 Update.

Current evidence indicates that dual antiplatelet therapy with aspirin plus a P2Y inhibitor is essential for the prevention of thrombotic events after percutaneous coronary interventions. However, dual antiplatelet therapy is associated with increased bleeding which may outweigh the benefits. This has set the foundations for customizing antiplatelet treatments to the individual patient.

Airway epithelium in lung transplantation: a potential actor for post-transplant complications?

Lung transplantation, a critical intervention for end-stage lung diseases, is frequently challenged by post-transplant complications. Indeed, primary graft dysfunction, anastomotic complications, infections and acute and chronic rejections pose significant hurdles in lung transplantation. While evidence regarding the role of airway epithelium after lung transplantation is still emerging, its importance is becoming increasingly recognised.

Quantitative muscle MRI combined with AI-based segmentation as a follow-up biomarker for ATTRv patients: A longitudinal pilot study.

Background And Objectives: Intramuscular fat fraction (FF), assessed using quantitative MRI (qMRI), has emerged as a promising biomarker for hereditary transthyretin amyloidosis (ATTRv) patients. Currently, the main drawbacks to its use in future therapeutic trials are its sensitivity to change over a short period of time and the time-consuming manual segmentation step to extract quantitative data. This pilot study aimed to demonstrate the suitability of an Artificial Intelligence-based (AI) segmentation technique to assess disease progression in a real-life cohort of ATTRv patients over 1 year.

Associations between malnutrition and dehydration among older adults: A cross-sectional observational study.

Background: There is debate as to the association between dehydration and malnutrition. Thus, this study aimed to investigate the correlation between dehydration and malnutrition and their impact on geriatric syndromes.

Methods: This cross-sectional study included older adults (≥60 years) who attended one outpatient geriatric clinic.
