The influence of selected processing variables on photographic film parameters of importance in optical data processing and holographic systems has been measured. Details of the tests chosen and their importance are given. Results are presented on amplitude transmittance, diffraction efficiency, and spatial frequency response characteristics for Kodak SO-243. Three developers (D-19, D-76, and Microdol-X) and two temperatures (24 degrees C and 30 degrees C) were chosen. The use of a gray base and the relatively low spatial frequency response somewhat limit the usefulness of this film. But for some applications its relatively fast speed may offset these features.

Background: Osteoporosis, a skeletal disorder affecting nearly 20% of the global population, poses a significant health concern, with osteoporotic vertebral body fractures (VBF) representing a common clinical manifestation. The impact of osteoporotic sintering fractures in the thoracolumbar spine on the sagittal lumbar profile is incompletely understood and may lead to the onset of clinical symptoms in previously asymptomatic patients.
Methods: This retrospective single-center study analyzed data from patients presenting with osteoporotic spine fractures between 2017 and 2022.

Background: The reasons for men not to seek healthcare seem similar across the world. They avoid going for regular medical check-ups, and preventive care and often disregard symptoms or delay seeking medical attention when sick, in pain, or even when their lives are in danger.
Methods: This study sought to explore the views of men on factors contributing to poor health-seeking behavior among men in Mopani, Vhembe, and Capricorn district municipalities in Limpopo Province.

Background: Staphylococcus aureus, a known contributor to non-healing wounds, releases vesicles (SAVs) that influence the delicate balance of host-pathogen interactions. Efferocytosis, a process by which macrophages clear apoptotic cells, plays a key role in successful wound healing. However, the precise impact of SAVs on wound repair and efferocytosis remains unknown.

Background: Self-management is regarded as a crucial factor influencing the effectiveness of home-based cardiac rehabilitation for patients with coronary heart disease. In nursing practice, nurses employ a variety of strategies to enhance self-management of patients. However, there exists a disparity in nurses' perceptions and practical experiences with these strategies.

Background: In The Gambia, existing research to understand and address malnutrition among adolescent girls is limited. Prior to the conduct of large-scale studies, formative research is needed. The aim of this mixed methods, cross-sectional study was to explore cultural contexts relevant to nutritional status, feasibility and appropriateness of recruitment and data collection methods (questionnaires and anthropometric measures), and plausibility of data collected.
