Probing the interaction of mannose-binding lectin with healthy and sickle cell anemia red blood cells and its role in cellular biomechanics.

Mannose-binding lectin (MBL) is an important glycoprotein of the human innate immune system. Furthermore, individuals with sickle cell anemia (SCA) and MBL deficiency seem more susceptible to vaso-occlusive crises, suggesting an MBL role on HbSS red blood cells (RBCs). This study investigated the interaction of MBL with HbA (healthy) and HbSS RBCs using optical tweezers (OT) and atomic force microscopy (AFM).

Testicular cryopreservation: From technical aspects to practical applications.

Testicular cryopreservation has been highlighted as a promising alternative for preserving male fertility and can be applied to restore spermatogenesis in prepubertal individuals or cancer patients, preserve biologically valuable genotypes, and in studies on reproductive physiology or toxicity of various substances. This review presents an analysis of the technical aspects and applications of testicular cryopreservation, examining the contributions of important studies in this area and discussing the different factors that can impact the efficiency of the technique. Testicular fragments can be obtained from living or dead individuals, at any age and reproductive stage, through orchiectomy or biopsy.

STZ-induced hyperglycemia differentially influences mitochondrial distribution and morphology in the habenulointerpeduncular circuit.

Introduction: Diabetes is a metabolic disorder of glucose homeostasis that is a significant risk factor for neurodegenerative diseases, such as Alzheimer's disease, as well as mood disorders, which often precede neurodegenerative conditions. We examined the medial habenulainterpeduncular nucleus (MHb-IPN), as this circuit plays crucial roles in mood regulation, has been linked to the development of diabetes after smoking, and is rich in cholinergic neurons, which are affected in other brain areas in Alzheimer's disease.

Methods: This study aimed to investigate the impact of streptozotocin (STZ)-induced hyperglycemia, a type 1 diabetes model, on mitochondrial and lipid homeostasis in 4% paraformaldehyde-fixed sections from the MHb and IPN of C57BL/6 J male mice, using a recently developed automated pipeline for mitochondrial analysis in confocal images.

Pressure injury prevention in an intensive care unit: implementing the best practices.

Objective: to implement the best evidence in preventing pressure injuries in patients in the intensive care unit of a university hospital in the city of São Paulo/Brazil.

Method: a quasi-experimental study whose intervention was implementing evidence based on the Joanna Briggs Institute methodology, which includes auditing and feedback. Ten audit criteria were used, which were verified in patient records and training records of the teaching and quality service.

Six-year clinical evaluation of a copper-containing universal adhesive in non-carious cervical lesions: A split-mouth double-blind randomized clinical trial.

Objectives: To evaluate the clinical performance of a universal adhesive system containing 0.1 % copper nanoparticles (CuNp) in non-carious cervical lesions (NCCLs) after 6 years.

Material And Methods: Two hundred and sixteen restorations (n = 54) were randomly placed in 36 participants with at least four NCCLs.
