Invasive Cardiopulmonary Exercise Testing in Chronic Thromboembolic Pulmonary Disease; Obesity and the V/VCO Relationship.

: Invasive cardiopulmonary exercise testing (iCPET) provides valuable insight into dyspnea in patients with chronic thromboembolic pulmonary disease, in part through an increased relationship of minute ventilation to CO production (V/VCO). Obesity lowers the V/VCO in patients without cardiopulmonary disease; however, whether this holds true in obese subjects with chronic thromboembolic pulmonary hypertension (CTEPH) and chronic thromboembolic pulmonary disease (CTEPD) is unknown. : Report on the iCPET findings of patients with CTEPH and CTEPD and investigate the relationship between obesity and gas exchange parameters, especially V/VCO in these patients.

Anaplastic Lymphoma Kinase (ALK) Inhibitors Enhance Phagocytosis Induced by CD47 Blockade in Sensitive and Resistant ALK-Driven Malignancies.

Background: Anaplastic lymphoma kinase (ALK) plays a role in the development of lymphoma, lung cancer and neuroblastoma. While tyrosine kinase inhibitors (TKIs) have improved treatment outcomes, relapse remains a challenge due to on-target mutations and off-target resistance mechanisms. ALK-positive (ALK+) tumors can evade the immune system, partly through tumor-associated macrophages (TAMs) that facilitate immune escape.

Behavioural, cognitive, and neurophysiological effects of a synbiotic supplementation enriched with pigmented corn extract or cornstarch in drug-naïve children with attention-deficit hyperactivity disorder: a randomised, double-blind, comparison-controlled clinical trial.

Background & Aims: Considerable interest has been recently given to the potential role of the gut-brain axis (GBA) -a two-way communication network between the gut microbiota and the central nervous system- in the pathogenesis of attention-deficit hyperactivity disorder (ADHD), suggesting the potential usefulness of probiotic and synbiotic supplementations. In light of the limited available evidence, synbiotic efficacy in ADHD children not taking medications should be clarified. This study aimed to investigate the efficacy of a synbiotic dietary supplementation on fatty acids levels as well as on microbiota composition, behaviour, cognition, and brain function in children with ADHD.

Nanoparticle shape is the game-changer for blood-brain barrier crossing and delivery through tunneling nanotubes among glioblastoma cells.

Tunneling nanotubes (TNTs) are thin, dynamic, long membrane protrusions that allow intercellular exchanges of signaling clues, molecules and organelles. The presence of TNTs and their involvement as drug delivery channels have been observed in several types of cancer, including glioblastoma. Recently, increased attention has been directed toward nanoparticles (NPs) that can be transported in TNTs.

The role of programmed death-ligand 1 (PDL-1) in high-grade cervical intraepithelial neoplasia (CIN2+) development and recurrence: A systematic review of literature about HPV-CIN2+-PDL-1 axis.

Background And Aims: Cervical intraepithelial neoplasia(CIN)and persistent high-risk human papillomavirus (HR-HPV)infection are associated with impaired local cellular immunity; however, the molecular mechanisms underlying these processes are not well understood. The involvement of the programmed death 1/programmed death 1 ligand (PD-1/PD-L1) pathway in the downregulation of T cell function has been demonstrated recently and it is believed to have a role in the onset and persistence of HPV infection and cervical cancer. Our aim is to analyze the role of PD-L1 in the CIN to identify a possible biomarker of HSIL (CIN2+) progression and persistence.
