Connecting lattice and molecular vibrations to organic crystal properties.

Understanding dynamic processes in molecular crystals is becoming crucial for the development of next-generation smart crystalline materials. In this context, Zwolenik & Makal [(2025). IUCrJ, 12, https://doi.

How do we transfuse children in Italy? Results of a national survey.

Background: Adherence to optimal practices in the preparation and issuance of pediatric blood components can significantly influence patient care outcomes. This study aims to examine the blood banking procedures across prominent Italian children's hospitals, with the goal of identifying both consistent and potentially divergent standards within this field.

Materials And Methods: A survey was conducted among the blood banks affiliated with the Italian Association of Pediatric Hospitals.

Psychophysiological indices of late-life depression: A systematic review.

Background: Major depression in the older population has a profound impact on patients' quality of life and is associated with an increased risk of developing several medical illnesses. Psychophysiological methods, such as electroencephalography (EEG), functional near-infrared spectroscopy (fNIRS), and eye-tracking, have provided evidence of physiological changes associated with depression in adult life. However, these aspects have not been thoroughly investigated during late-life (over 60 years of age).

The Italian registry of therapeutic apheresis in SISTRA: Year of activity 2023.

The Italian Registry of Therapeutic Apheresis (IRTA) collects clinical data on patients undergoing therapeutic apheresis procedures throughout the national territory, with the main objective of improving the quality and safety of the care provided to the patient. Given the importance of centralizing the collection and analysis of information on therapeutic apheresis, the National Blood Center (NBC), at the request of the Italian Scientific Society of Hemapheresis and Cellular Manipulation (SIdEM), has included IRTA in the Information System of Transfusion Services (SISTRA), which is the information system of the Ministry of Health for the exchange of data on blood and its derivatives between the Italian Regions and the NBC. This manuscript reports IRTA activity data for 2023 maintaining the general approach introduced in previous manuscripts to facilitate comparison with already published activity data (2020-2022).

Toward On-Demand Polymorphic Transitions of Organic Crystals via Side Chain and Lattice Dynamics Engineering.

Controlling polymorphism, namely, the occurrence of multiple crystal forms for a given compound, is still an open technological challenge that needs to be addressed for the reliable manufacturing of crystalline functional materials. Here, we devised a series of 13 organic crystals engineered to embody molecular fragments undergoing specific nanoscale motion anticipated to drive cooperative order-disorder phase transitions. By combining polarized optical microscopy coupled with a heating/cooling stage, differential scanning calorimetry, X-ray diffraction, low-frequency Raman spectroscopy, and calculations (density functional theory and molecular dynamics), we proved the occurrence of cooperative transitions in all the crystalline systems, and we demonstrated how both the molecular structure and lattice dynamics play crucial roles in these peculiar solid-to-solid transformations.
