Histopathology of the tongue in a hamster model of COVID-19.

Objective: With altered sense of taste being a common symptom of coronavirus disease 2019 (COVID-19), the main objective was to investigate the presence and distribution of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) within the tongue over the course of infection.

Methods: Golden Syrian hamsters were inoculated intranasally with SARS-CoV-2 and tongues were collected at 2, 3, 5, 8, 17, 21, 35, and 42 days post-infection (dpi) for analysis. In order to test for gross changes in the tongue, the papillae of the tongue were counted.

Persistent sleep apnea after adenotonsillectomy in pediatric patients with head and neck burns.

Background: To determine if face, head, or neck burns increases risk of persistent sleep disordered breathing (SDB) or obstructive sleep apnea (OSA) after adenotonsillectomy.

Methods: The TriNetX database was used to gather data for patients who had face, head, or neck burn including mouth and pharynx and history of sleep study with adenotonsillectomy. A comparison of persistent SDB or OSA was done between cohort 1, a group with sleep study and adenotonsillectomy after burn injury, and cohort 2, a group with treatment before a burn.

Biallelic Variants in LRRC45 Impair Ciliogenesis and Cause a Severe Neurological Disorder.

Leucine - rich repeat containing 45 protein (LRRC45) protein localizes at the proximal end of centrioles and forms a component of the proteinaceous linker between them, with an important role in centrosome cohesion. In addition, a pool of it localizes at the distal appendages of the modified parent centriole that forms the primary cilium and it has essential functions in the establishment of the transition zone and axonemal extension during early ciliogenesis. Here, we describe three individuals from two unrelated families with severe central nervous system anomalies.

Synthesis, characterization, genotoxicity assessment and antibacterial applications of silver nanoparticles (ZASNPs) with antibiotic efficacy enhancement potential.

This study aimed to develop alternative antibacterial treatments by combining traditional herbal knowledge with modern nanotechnology. This approach targets multiple bacterial strains, combats antibiotic resistance, and offers solutions for treating infections alone or with antibiotics. Phyto-nano synthesis, using plants like DC.

Assessment of cardiac and skeletal muscle metabolites using H-MRS and chemical-shift encoded magnetic resonance imaging: Impact of diabetes, RAGE, and DIAPH1.

Diabetes affects metabolism and metabolite concentrations in multiple organs. Previous preclinical studies have shown that receptor for advanced glycation end products (RAGE, gene symbol Ager) and its cytoplasmic domain binding partner, Diaphanous-1 (DIAPH1), are key mediators of diabetic micro- and macro-vascular complications. In this study, we used H-Magnetic Resonance Spectroscopy (MRS) and chemical shift encoded (CSE) Magnetic Resonance Imaging (MRI) to investigate the metabolite and water-fat fraction in the heart and hind limb muscle in a murine model of type 1 diabetes (T1D) and to determine if the metabolite changes in the heart and hind limb are influenced by (a) deletion of Ager or Diaph1 and (b) pharmacological blockade of RAGE-DIAPH1 interaction in mice.
