Apical surgery for a mandibular molar is still challenging for many reasons. This report describes the applications of computer-guided cortical ‘bone-window technique’ using piezoelectric saws that prevented any nerve damage in performing endodontic microsurgery of a mandibular molar. A 49-year-old...

IntroductionThe anterior insular cortex (AIC) integrates interoceptive, cognitive-emotional, and error-monitoring signals, and is consistently hyperactive in anxiety and depression. Converging evidence links elevated glutamate + glutamine (Glx) in fronto-insular regions to stress reactivity; however...

Additive manufacturing (AM) techniques can print multiple materials to realise three-dimensional products with increased complexity not only in their shapes but also in their mechanical behaviour. Here, we study hot-end co-extrusion printing of multiple thermoplastic filaments. By co-extrusion print...

Estimating the economic value of recreation and ecotourism is essential for sustainable ecosystem management and informed environmental policymaking. However, values derived from individual studies often vary because of subjective preferences and contextual variability, making it challenging to obta...

The Asian longhorned tick (Haemaphysalis longicornis) is an ectoparasite that transmits several pathogens, including severe fever with thrombocytopenia syndrome virus, to humans and animals. Wild populations of H. longicornis are maintained by both bisexual and asexual reproductive strategies. This...

Engrams corresponding to distinct memories compete for retrieval in the CA3 region of the hippocampus, yet the detailed mechanisms underlying their formation remain elusive. Recent findings indicate that hippocampal inhibitory neurons display feature-selective firing patterns and diverse forms of sy...

The goal of this paper is to optimize mission schedules for vertical airports (vertiports in short) to satisfy the different needs of stakeholders. We model the problem as a resource-constrained project scheduling problem (RCPSP) to obtain the best resource allocation and schedule. As a new approach...

Sarcopenia, the age-related loss of muscle mass, strength, and performance, is a significant concern in the aging population. Despite extensive research, no consensus exists on its prevention and treatment. Sarcopenia increases the risk of functional disability, falls, hospitalization, long-term car...

Sperm storage is a crucial reproductive adaptation that ensures fertilization success by maintaining viable sperm until ovulation. Birds and mammals have evolved anatomically distinct yet functionally analogous structures, sperm storage tubules (SSTs) in the avian female reproductive tract and the e...
