The effects of sleep deprivation on the balance system: following normal sleep, 24 h of sleep deprivation, and rest under eyes-open and eyes-closed conditions.

Objective: This study investigated the effects of sleep deprivation (SD) on balance after normal sleep, 24 h of SD, and subsequent rest under eyes-open (EO) and eyes-closed (EC) conditions. Our aim was to ascertain whether the reduced efficiency of balance control following SD is generalized or selective.

Method: Nineteen participants (12 females, 7 males) completed the Pittsburgh Sleep Quality Index (PSQI).

Analysis of depressions indicative of dural venous sinuses within the intracranial cavities of skull bases.

Purpose: This study aimed to examine the anatomical variations and morphometric characteristics of the sulci in the dural venous sinuses within the intracranial cavity, with a particular focus on sex differences and asymmetry.

Methods: Thirty fixed cadaveric heads were used to measure the dimensions (length, width, and depth) and spatial relationships of the dural venous sinus sulci within the intracranial cavity, including the distance to the midline, distance to each other, and lateral margin of the skull. Comparisons were made between sexes and sides of the body.

Unilateral two-headed extensor digitorum longus muscle: atypical configuration and clinical implications.

This report describes a new configuration of the extensor digitorum longus (EDL) with two heads and two main tendons divided into four slips. During routine cadaver dissection, unilateral (right) EDL muscle belly and tendon variations were identified. The morphometric measurements of the EDL were conducted using Image J software.

Quantitative analysis of surgical landmarks of the face in fixed cadaveric heads: clinical and anatomical implications.

Purpose: This study aimed to examine and analyze the presence of sexual dimorphism and symmetry/asymmetry in fixed cadaveric heads and their contributions to clinical practice.

Methods: Measurements were conducted on 6 cadavers and 24 fixed cadaveric heads (n = 30) using a digital microcaliper to assess cranial dimensions, including surgical landmarks, facial index (FI), orbital index (OI), and the danger triangle of the face, offering crucial references for surgeons during surgical interventions.

Results: Analyses were conducted on cadavers consisting of 10 females (33.
