Dendritic spines are tiny protrusions emanating from the neuronal dendrites, typically housing single excitatory postsynapses. Structural plasticity of dendritic spines is considered to be essential for synaptic functional plasticity and also reorganization of neural circuits during learning and memory. Structural plasticity of spines is mediated by complex biochemical signaling with various spatial and temporal scales. A variety of methods based on pharmacological, genetic, molecular, imaging and optical approaches has been developed and applied to dissect the complex signal transduction pathways. In this review, we overview both conventional and new methodological approaches to identify, monitor and manipulate key molecules for structural plasticity of dendritic spines, ultimately aiming to understand the molecular mechanism of learning and memory in behaving animals.

Background: Phthalates are compounds used as plasticizers to increase the flexibility of plastics and are considered endocrine disruptors. Some studies suggest that the origin of prostate cancer (PCa) may be associated with disturbances during embryo-fetal development. Previous data showed that perinatal exposure to the same phthalate mixture (PM) used here increased the incidence of adenocarcinomas in the prostates of aged rats.

Plastics are widely used materials composed of polymers and various additives to achieve specific properties. Their composition is often highly complex, particularly in post-consumer plastic waste. As mechanical recycling faces increasing limitations, chemistry-driven strategies are attracting growing interest to improve plastic recovery.

Leadership is increasingly recognised as an essential non-technical skill for effective surgical practice, particularly in oral and maxillofacial surgery (OMFS) due to its multidisciplinary nature and clinical scope. The aim of this review is to identify current leadership development opportunities available to UK OMFS specialty trainees, evaluate their sufficiency, and propose areas for improvement. A comprehensive search of published and grey literature was conducted, screening 2796 articles, with 18 meeting the inclusion criteria.

Drug-resistant epilepsy (DRE) is frequently characterized by pathological mossy fiber sprouting (MFS), which is a defining indicator of aberrant synaptic remodeling within the hippocampus. Despite extensive investigations of the molecular underpinnings of MFS, they remain only partially elucidated. Synaptic vesicle protein 2A (SV2A) is a key modulator of neurotransmitter exocytosis that has been associated with epileptogenesis.

This study provides valuable guidance for simplifying fabrication procedures and enhancing the structural integrity and safety of carbon fiber (CF) laminate transfemoral (TF) prosthetic sockets. While the high specific strength of CF laminate sockets offers advantages over conventional plastics, essential production data-their orientation-dependent strength and optimal cure conditions-are lacking, often requiring complex, costly cure cycles. This study investigated (i) the influence of fiber orientation on TF prosthetic CF socket strength via finite element analysis (FEA) during standing, and (ii) optimal single-step Vacuum-Bag-Only (VBO) cure conditions for prepreg in a low-cost conventional oven.
