Cardiovascular Issues in Tyrosine Kinase Inhibitors Treatments for Chronic Myeloid Leukemia: A Review
2021
Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm driven by a fusion gene, encoding for the chimeric protein BCR-ABL, with constitutive tyrosine kinase activity. The use of tyrosine kinase inhibitors (TKIs) has drastically improved survival, but there are significant concerns about cardiovascular toxicity. Cardiovascular risk can be lowered with appropriate baseline evaluation, accurate choice of TKI therapy, improvement of modifiable cardiovascular risk factors through lifestyle modifications, and prescription of drugs for primary or secondary prevention. Which examinations are necessary, and when do they have to be scheduled? How often should a TKI-treated patient undergo wh…

Evaluation of Mucociliary Clearance by Three Dimension Micro-CT-SPECT in Guinea Pig: Role of Bitter Taste Agonists
2016
Different image techniques have been used to analyze mucociliary clearance (MCC) in humans, but current small animal MCC analysis using in vivo imaging has not been well defined. Bitter taste receptor (T2R) agonists increase ciliary beat frequency (CBF) and cause bronchodilation but their effects in vivo are not well understood. This work analyzes in vivo nasal and bronchial MCC in guinea pig animals using three dimension (3D) microCT-SPECT images and evaluates the effect of T2R agonists. Intranasal macroaggreggates of albumin-Technetium 99 metastable (MAA-Tc99m) and lung nebulized Tc99m albumin nanocolloids were used to analyze the effect of T2R agonists on nasal and bronchial MCC respecti…
Mesopolysaccharides: The extracellular surface layer of visceral organs
2020
The mesothelium is a dynamic and specialized tissue layer that covers the somatic cavities (pleural, peritoneal, and pericardial) as well as the surface of the visceral organs such as the lung, heart, liver, bowel and tunica vaginalis testis. The potential therapeutic manipulation of visceral organs has been complicated by the carbohydrate surface layer—here, called the mesopolysaccharide (MPS)—that coats the outer layer of the mesothelium. The traditional understanding of MPS structure has relied upon fixation techniques known to degrade carbohydrates. The recent development of carbohydrate-preserving fixation for high resolution imaging techniques has provided an opportunity to re-examine…
New insights in primary ciliary dyskinesia
2017
Introduction: Primary ciliary dyskinesia (PCD) is a rare genetic disease with an estimated prevalence of 1:20.000 births. It is characterized by abnormal motility of cilia, leading to impaired mucociliary clearance, and subsequent infection and chronic inflammation of the airways. PCD also affects spermatozoa and cilia in the Fallopian tubes, contributing to fertility issues; dyskinesia of embryonic nodal cilia causes a random distribution of the organs. Areas covered: An overview of the history, genetics, clinical manifestations in children and adults, diagnostic tests, treatments, and prognosis are reviewed. We also discuss current research and future prospects of PCD. Expert opinion: As …
Potential Influence of Helminth Molecules on COVID-19 Pathology
2020
In recent months, the parasitology research community has been tasked with investigation of the influence of parasite coinfection on coronavirus disease 2019 (COVID-19) outcomes. Herein, we share our approach to analyze the effect of the trematode Fasciola hepatica as a modulator of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and of COVID-19 pathology.
Cystic fibrosis treatment: targeting the basic defect
2017
ABSTRACTIntroduction: Cystic Fibrosis (CF) is a disease caused by different class mutations in the CF transmembrane conductance regulator (CFTR) gene. It can therefore benefit from a personalized medicine approach based on the individual genotype of each patient.Areas covered: This review provides a detailed overview of the current major development of new CF treatments that target the basic CF defect. The review summarizes gene therapy, mRNA repair strategies, read-through agents, and CFTR-modulators (potentiators, correctors, stabilizers, amplifiers and different combination therapies).Expert opinion: We are currently perhaps at the most exciting stage in the history of CF, with the poten…
TTF-1/p63-Positive Poorly Differentiated NSCLC: A Histogenetic Hypothesis from the Basal Reserve Cell of the Terminal Respiratory Unit
2020
TTF-1 is expressed in the alveolar epithelium and in the basal cells of distal terminal bronchioles. It is considered the most sensitive and specific marker to define the adenocarcinoma arising from the terminal respiratory unit (TRU). TTF-1, CK7, CK5/6, p63 and p40 are useful for typifying the majority of non-small-cell lung cancers, with TTF and CK7 being typically expressed in adenocarcinomas and the latter three being expressed in squamous cell carcinoma. As tumors with coexpression of both TTF-1 and p63 in the same cells are rare, we describe different cases that coexpress them, suggesting a histogenetic hypothesis of their origin. We report 10 cases of poorly differentiated non-small-…
