Babesiosis and Sickle Red blood Cells: Loss of Deformability, Heightened Osmotic fragility, and Hypervesiculation.

Babesiosis in sickle cell disease (SCD) is marked by severe anemia but the underlying red blood cell (RBC) rheological parameters remain largely undefined. Here, we describe altered RBC deformability from both primary (host RBC sickle hemoglobin mediated) and secondary changes (Babesia parasite infection mediated) to the RBC membrane using wild type AA, sickle trait AS and sickle SS RBCs. Our ektacytometry (LORRCA) analysis demonstrates that the changes in the host RBC bio-mechanical properties, pre- and post- Babesia infection, reside on a spectrum of severity, with wild type infected AA cells, despite showing a significant reduction of deformability under both shear and osmolarity gradients, exhibiting only a mild phenotype; compared to infected AS RBCs which show median changes in deformability and infected SS RBCs which exhibit the most dramatic impact of infection on cellular rheology, including an increase in Point of Sickling values.

Pandemic Perceptions and Healthcare Decisions: Exploring Perceived COVID-19 Threat's Impact on Perinatal Healthcare in Florida.

The COVID-19 pandemic directly impacted well-being and healthcare delivery, but its indirect effects on health services utilization among pregnant women and new mothers remain less understood. Understanding how big events like pandemics impact health behaviors is essential for anticipating healthcare needs during future crises. This study examined how the perceived COVID-19 threat influenced health concerns and service utilization among 378 participants who were either pregnant or mothers of infants less than 12 months old, 18 years or older, and lived within a 50-mile radius of healthcare sites in the OneFlorida+ Clinical Research Consortium.

Direct analysis of engineered iron nanotubes and platinum nanorods: A challenge for single particle inductively coupled plasma mass spectrometry.

The use of inductively coupled plasma mass spectrometry in single particle mode (SP-ICP-MS) for the characterization of micro and nanostructured materials is a growing field of research. In this work, the possibility of expanding the boundaries to anisotropic structures including solid Pt-nanorods and hollowed FeO-nanotubes is presented. The obtained structures are evaluated by scanning electron microscopy (SEM), high-resolution electron microscopy (HR-TEM) and SP-ICP-MS techniques.

Insights into Reproduction Through Gonadal Tissue Methylation Analysis and Transcriptomic Integration.

Fish exhibit diverse mechanisms of sex differentiation and determination, shaped by both external and internal influences, often regulated by distinct DNA methylation patterns responding to environmental changes. In aquaculture, reproductive issues in captivity pose significant challenges, particularly the lack of fertilization capabilities in captive-bred males, hindering genetic improvement measures. This study analyzed the methylation patterns and transcriptomic profiles in gonadal tissue DNA from groups differing in rearing conditions and sexual maturity stages.

Antithrombotic prophylaxis use and incidence of venous thromboembolism in lung cancer surgery: An observational retrospective study.

Introduction: Extended thromboprophylaxis with low-molecular-weight heparin (LMWH) for 28 days is recommended in patients undergoing major abdominal or pelvic cancer surgery, but the evidence for thoracic cancer surgery is weak. We aimed to evaluate the use of pharmacological thromboprophylaxis and incidence of venous thromboembolism (VTE) in adult patients undergoing lung cancer surgery in daily clinical practice.

Methods: Retrospective evaluation of a cohort of consecutive adult patients who had undergone lung cancer surgery.
