Article Abstract
Objective: To identify the typical pattern of changes of vestibular-evoked myogenic potentials (VEMPs) and explore the relationship between VEMPs and the anthropometry factors in patients with obstructive sleep apnea (OSA).
Methods: Patients diagnosed as OSA after overnight polysomnography (PSG) tests were enrolled as the study group. Healthy volunteers were recruited as the control group. Anthropometry data of the body shape and VEMPs results were collected completely. The correlation analysis was conducted among those parameters.
Results: Forty-nine patients with OSA who were diagnosed in the Therapy Center of Sleep-disordered Breathing in our hospital and sex- and age-matched healthy controls as well. Significant changes in ocular and cervical VEMPs (oVEMP and cVEMP) in the study group were observed, which were reduced response rates, elevated thresholds, decreased amplitudes, and prolonged first wave latencies. In oVEMP, the first wave (n1) latency was significantly correlated with weight, body mass index (BMI), neck circumference, waist circumference, hip circumference, and apnea hypopnea index (AHI). In a tentative application, combined use of BMI and oVEMP n1 latency increased the detection rate during OSA screening prior to PSG.
Conclusion: OSA can negatively affect function of otolithic organs and their pathways. The first wave latency of the VEMPs waveform may be another important parameter to define peripheral nervous system lesions caused by systemic diseases as OSA.

Since its use during the COVID-19 pandemic, mRNA has emerged as a leading candidate vaccine platform for pandemic infections. A critical difference between RNA-encoded antigen and protein vaccines is that RNA-based vaccines require the antigen to be translated in the body, adding an important variable. Much of the research focus in the field has been on ways to increase expression, but inflammation plays a critical role.

Objectives: This study aimed to examine physical and craniofacial growth patterns in preschool-aged children with microcephaly and evaluate their potential clinical significance.
Methods: A total of 130 children (76 boys, 54 girls) aged 1-5 years with microcephaly (head circumference <-3 standard deviations) were enrolled in this prospective study at a tertiary care hospital, with 130 age- and sex-matched healthy controls. Nine craniofacial dimensions (head circumference, head length, head width, physiognomic facial length, morphological facial length, minimum frontal diameter, bizygomatic diameter, bigonial diameter, and total jaw height) were measured every six months using standardized techniques and instruments.

Tires are complex polymeric materials composed of rubber elastomers (both natural and synthetic), fillers, steel wire, textiles, and a range of antioxidant and curing systems. These constituents are distributed differently among the various tire parts, which are classified based on their function and proximity to the rim. This study presents a rapid and sensitive approach for the characterization of tire components using mild thermal desorption/pyrolysis (TDPy) coupled to direct analysis in real-time mass spectrometry (DART-MS).

Who is perceived as a leader? Traditional theories of leader categorization have primarily emphasized observable behaviors as the key basis for making this judgment. However, a growing body of research shows that perceivers rely on a broader set of cues-beyond behavior alone-that differentially shape leadership attributions. To integrate these perspectives, we present a comprehensive review of how multiple-and sometimes competing-cues are perceived, interpreted, and activated as traits in the leader categorization process.
