Background: Authors aim to evaluate the correct placement of TDR using the instant center of rotation (ICR) as a guide.
Methods: Placement of disc would be divided into three groups using a standard of 1 mm from the ICR: Posterior to ICR, In line with ICR and Anterior to ICR.
Results: 49 patients, mean age was 39.96 ± 1.45 years. 42 intraop fluoroscopy images compared to 41 post op radiographic images demonstrated TDR in line with ICR.
Conclusion: Total discs replacements can be placed intraoperatively using proper technique with verification confirmed using the ICR postoperatively.
Keywords: Total disc replacement; instant center of rotation; ideal placement; fluoroscopy; adjacent segment disease; less exposure surgery.

Disturbance-Triggered Instant Crystallization Activating Bioinspired Emissive Gels.
Angew Chem Int Ed Engl

Many marine organisms feature sensitive sensory-perceptual systems to sense the surrounding environment and respond to disturbance with intense bioluminescence. However, it remains a great challenge to develop artificial materials that can sense external disturbance and simultaneously activate intense luminescence, although such materials are attractive for visual sensing and intelligent displays. Herein, we present a new class of bioinspired smart gels constructed by integrating hydrophilic polymeric networks, metastable supersaturated salt and fluorophores containing heterogenic atoms.

Cancer remains as a global health threat, with the incidence of breast cancers keep increasing. Dis-regulated redox homeostasis has been considered with essential roles for tumor initiation and progression. Using triple negative breast cancers, the most malignant subtype of breast cancers, as the tumor model, we explored the roles of the anti-oxidant spermidine, the pro-oxidative tool cold atmospheric plasma (CAP), and their combined use in cancer growth, anti-oxidative ability and cell cycle.

Introduction: We examined semantic and phonemic fluency in individuals with subjective cognitive decline (SCD) in relation to amyloid status and clinical progression.
Methods: A total of 490 individuals with SCD (62 ± 8 years, 42% female, 28% amyloid-positive, 17% clinical progression) completed annual fluency assessments (mean ± SD follow-up 4.3 ± 2.
Formative evaluation of a mobile chat-based intervention (ChatEx) for promoting exercise behaviour in older cancer survivors.

School of Nursing, Li Ka Shing Faculty of Medicine, The University of Hong Kong, Hong Kong.
Purpose: To conduct a formative evaluation of ChatEx to increase and maintain exercise among older cancer survivors.
Methods: ChatEx is a blended intervention involving 12 weeks of theory-based instant messages and two in-person training sessions. This pilot study comprises three phases: (1)intervention development: developing a message library reviewed by experts; (2)message library pretesting: exploring the views of older cancer survivors toward the message library and making modifications (n = 20); and (3)intervention pilot testing: piloting the ChatEx using a non-randomized quasi-experimental design using quantitative and qualitative methods among cancer survivors aged 65+ who do not meet current exercise guidelines and have completed treatment (n = 40).
Valorization of Rosehip ( L.) Pomace Using Unconventional Carbohydrate Carriers for Beverage Obtainment.

Institute of Life Sciences, School of Engineering, University of Applied Sciences and Arts Western Switzerland (HES-SO Valais Wallis), Rue de l'Industrie 19, 1950 Sion, Switzerland.
Rosehip is of notable scientific interest due to its rich content of bioactives and its wide-ranging applications in nutrition, cosmetics and pharmaceuticals. The valorization of rosehip by-products, such as pomace, is highly significant for promoting sustainability. This study investigates the development of rosehip-based powders and beverage prototypes derived from both juice and pomace to evaluate the potential use of pomace in instant beverage design and compare it with juice-based formulations.
