An Experimental Study on the Protective Effect of Memantine in Noise‐Induced Hearing Loss

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective This study examined the potential protective effects of memantine, an N‐methyl‐D‐aspartate (NMDA) receptor antagonist, against acoustic trauma (AT) in guinea pigs, using electrophysiological and histopathological analyses. Methods Thirty guinea pigs with normal hearing were divided into six groups (n = 5 per group): Group 1 (control),

Perilymph Gusher in Cochlear Implantation Surgery: An Algorithm for Management

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective Perilymph leak is considered a major complication of cochlear implantation (CI) surgery and can lead to surgical difficulties and postoperative morbidities. This study is aimed to formulate an algorithm for better management of perilymph leak in cases of CI. Methods This is a retrospective study conducted in our tertiary institute on

Recent progress in studies of the last million years of human physical and behavioural evolution Avancées récentes dans l’étude du dernier million d'années d’évolution physique et éthologique de l'espèce humaine

Journal of the Royal Anthropological Institute, EarlyView.
This article presents a synthesis of recent developments in the study of human evolution over the past five years. It begins with an overview of hominin species nomenclature and diversity, followed by an examination of the proposed population bottleneck ∼900,000 years ago.

Hoffmann's two‐toed sloth I: Complete myology in the thoracic limb of Choloepus (Pilosa: Xenarthra)

Journal of Anatomy, EarlyView.
Two‐toed sloths use their thoracic limbs for more frequent and prolonged suspensory support than three‐toed sloths and accordingly demonstrate myological traits consistent with stability of the pectoral girdle, enhanced flexor force/torque applied at the elbow joint, and grip on the support.

Virtual brain endocasts of the palaeanodont Metacheiromys marshi and the neurosensory evolution of early Pholidotamorpha

Journal of Anatomy, EarlyView.
We describe the endocranial anatomy of Metacheiromys marshi. Decrease in olfaction and eye movement control occurred through time in Pholidotamorpha and is likely linked to fossorial adaptations. The development of the orbital gyrus might be related to the evolution of myrmecophagy and the emergence of a protrusile tongue in early Pholidotamorpha ...

Narcissism Is Associated With Blunted Error‐Related Brain Activity

Journal of Personality, EarlyView.
ABSTRACT Objective Narcissism is associated with self‐enhancement and social antagonism, yet its neural underpinnings, particularly in error processing, remain underexplored. Competing theoretical models, such as the mask model and the metacognitive model, offer conflicting hypotheses regarding how narcissism influences early neural responses to errors.

The Interplay Between Emotion Dysregulation and Repetitive Thoughts in Insomnia Disorder: The Impact of Worry, Rumination and REM Sleep Instability

Journal of Sleep Research, EarlyView.
ABSTRACT While previous research has identified emotional dysregulation and repetitive thinking as contributors to insomnia, the interplay between these factors remains unclear. Building upon data previously collected in our laboratory, this exploratory study extends prior findings by examining the mediating role of rumination, worry and rapid eye ...
