Objective: This study aims to present a case of temporal bone (TBP) paraganglioma with an insidious clinical presentation, deviating significantly from the typical hearing loss and pulsatile tinnitus pattern.

Methods: A 70-year-old lady presented to the emergency department with a five-day history of right progressive later cervical swelling extending to the mastoid region and chronic worsening purulent otorrhea. The clinical and radiological findings confirmed the presence of a chronic middle ear process complicated by a Bezold abscess.

Background Dacryocystitis (DC) is a disease most often caused by an obstruction of the nasolacrimal duct, leading to over-accumulation of tears in the lacrimal sac, epiphora, and aseptic inflammation. External and endoscopic dacryocystorhinostomy (DCR) aims to restore the tear pathway by creating a bypass from the lacrimal sac to the nose. The aim of this study is to investigate superior nasal septal deviation as a possible contributing factor in the incidence and treatment of dacryocystitis.

Chemical-nose/tongue technologies are emerging as promising analytical tools for glycan analysis. After briefly introducing the importance of glycans and their analytical methods, including the lectin microarray (LMA) as one of the gold standards, the fundamental principles underlying chemical noses/tongues are explained and various applications for monosaccharides and glycans are introduced. Then, the similarities and differences of these two approaches are discussed.

Many witnesses are intoxicated at crime scenes, yet little is known of their ability to accurately describe perpetrators to police. We therefore explored the impact of alcohol on delayed verbal face recall across two experiments. Participants were administered an alcoholic or non-alcoholic beverage prior to viewing either one or two unfamiliar female faces, which they described from memory the following day while in a sober state.

Single-cell RNA-sequencing (scRNA-seq) is a powerful method to comprehensively overlook gene expression profiles of individual cells in various tissues, providing fundamental datasets for classification of cell types and further functional analyses. Here we adopted scRNA-seq analysis for the zebrafish olfactory sensory neurons which respond to water-borne odorants and pheromones to elicit various behaviors crucial for survival and species preservation. Firstly, a single-cell dissociation procedure of the zebrafish olfactory rosettes was optimized by using cold-active protease, minimizing artifactual neuronal activation.

Background: Osteoarthritis (OA) often leads to pain and functional limitations, impacting work and daily life. Physical activity (PA) is an important part of the treatment. Wearable activity trackers (WATs) offer a novel approach to promote PA but could also aid in finding a sustainable PA level over time.

Currently, the direct endonasal approach is widely used in endoscopic endonasal surgery (EES) for pituitary neuroendocrine tumor. However, a large posterior septal perforation is inevitable. We routinely utilize a modified para/transseptal approach using the combination of a Killian and a contralateral rescue flap incision (PTSA with K-R incision).

Nose-to-brain delivery of DHA-loaded nanoemulsions: A promising approach against Alzheimer's disease.

Int J Pharm

MMDN, University of Montpellier, EPHE, INSERM, Montpellier, France; LipSTIC LabEx (ANR-11-LABX0021), Dijon, France. Electronic address:

Reduced docosahexaenoic acid (DHA) concentrations seem to be associated with an increased risk of Alzheimer's disease (AD), and DHA accretion to the brain across the blood-brain-barrier (BBB) can be modulated by various factors. Therefore, there is an urgent need to identify an efficient and non-invasive method to ensure brain DHA enrichment. In the present study, a safe and stable DHA-enriched nanoemulsion, designed to protect DHA against oxidation, was designed and administered intranasally in a transgenic mouse model of AD, the J20 mice.

January 2025

Department of Applied Animal Science and Welfare, Swedish University of Agricultural Sciences, 750 07 Uppsala, Sweden; The Beijer Laboratory for Animal Science, Faculty for Vet. Med. and Animal Science, SLU, 750 07 Uppsala, Sweden.

In cow-calf contact (CCC) systems breaking the maternal bond may induce stress for the cow, thereby affecting feed intake, milk yield, milk flow rate, and milk electrical conductivity. This study aimed to determine the consequences of weaning and separation strategies in CCC systems for feed intake and milking characteristics of the cow. In 2 experiments, Swedish Holstein and Swedish Red cows either had (experiment 1) whole-day CCC (CCC1, n = 12) for 8.

January 2025

Department of Otorhinolaryngology, Head and Neck surgery, Aichi Medical University School of Medicine, 1-1, Yazakokarimata, Nagakute, Aichi 480-1195, Japan.

We present a case of a perilymphatic fistula (PLF) caused by Eustachian tube air inflation (ETAI) that was diagnosed using cochlin-tomoprotein (CTP) testing and successfully treated using transcanal endoscopic ear surgery to seal the inner ear window. A 77-year-old woman developed hearing loss and dizziness after undergoing ETAI at a local ear, nose, and throat clinic. Despite initial bed rest and steroid pulse therapy, the hearing did not improve, and transcanal endoscopic ear surgery was performed to repair the PLF.

Background: Noninvasive mechanical ventilation (NIMV), when in synchronized intermittent mandatory ventilation, continuous positive airway pressure, or patient-triggered ventilation modes, is known to be a cause of facial, nasal, head, and skin pressure injuries in preterm infants.

Objective: The objective of this study is to examine the efficacy of using a checklist with preterm infants under nasal NIMV in preventing facial, nasal, and head pressure injuries.

Method: The study was conducted quasi-experimentally on preterm infants under NIMV.

Background: Unilateral cleft lip secondary nasal deformities are common and require surgical correction frequently. The nasal dome on the cleft side is depressed, and the nasal ala is in an extended and flattened position compared with the noncleft side. In addition, the nasal septum is deviated into the cleft nostril.

Montelukast, a leukotriene receptor antagonist (LTRA) approved for the treatment of asthma and allergic rhinitis, is widely used, though real-world data on its application in asthma management remain limited. This registry-based study evaluated the use of montelukast in adult asthma patients, examining demographic and disease characteristics, asthma control status, asthma phenotypes, presence of atopy, and treatment regimens. Among 2053 patients analyzed, 61.

Background: Pathobiology of asthma and chronic obstructive pulmonary disease (COPD) is associated with changes among respiratory epithelium structure and function. Increased levels of PM from urban particulate matter (UPM) are correlated with enlarged rate of asthma and COPD morbidity as well as acute disease exacerbation. It has been suggested that pre-existing pulmonary obstructive diseases predispose epithelium for different biological response than in healthy airways.

Facial signals shape predictions about the nature of upcoming conversational responses.

January 2025

Donders Institute for Brain, Cognition and Behaviour, Radboud University, Wundtlaan 1, 6525 XD Nijmegen, Nijmegen, The Netherlands.

Increasing evidence suggests that interlocutors use visual communicative signals to form predictions about unfolding utterances, but there is little data on the predictive potential of facial signals in conversation. In an online experiment with virtual agents, we examine whether facial signals produced by an addressee may allow speakers to anticipate the response to a question before it is given. Participants (n = 80) viewed videos of short conversation fragments between two virtual humans.

Whole utilization of okara has important economic value, but there are two technical barriers: coarse mouthfeel caused by insoluble dietary fiber (IDF) and undesirable "beany" off-odors. UV-A irradiation and/or microbial fermentation were used to modify okara. The results indicated that single and combined treatments increased the soluble dietary fiber (SDF) content.
