Olfactory dysfunction is considered a pre-cognitive biomarker of Alzheimer's disease (AD). Because the olfactory system is highly conserved across species, mouse models corresponding to various AD etiologies have been bred and used in numerous studies on olfactory disorders. The olfactory behavior test is a method required for early olfactory dysfunction detection in AD model mice. Here, we review the olfactory evaluation of AD model mice, focusing on traditional olfactory detection methods, olfactory behavior involving the olfactory cortex, and the results of olfactory behavior in AD model mice, aiming to provide some inspiration for further development of olfactory detection methods in AD model mice.

Lung cancer represents a significant global health burden, with non-small cell lung cancer (NSCLC) being the most common subtype. The current standard of care for NSCLC has limited efficacy, highlighting the necessity for innovative treatment options. Lidocaine, traditionally recognized as a local anesthetic, has emerged as a compound with potential antitumor and anti-inflammatory capabilities.

Nuclear factor of activated T-cells 5 (NFAT5) is a transcription factor known for its role in osmotic stress adaptation in the renal inner medulla, due to the osmotic gradient that is generated between the renal cortex and renal inner medulla. However, its broader implications in kidney injury and chronic kidney disease (CKD) are less understood. Here we used two different Cre deleter mice (Ksp1.

Background: Exogenous Cushing's syndrome, which results from prolonged glucocorticoid treatment, is associated with metabolic abnormalities. Previously, we reported the inhibitory effect of tonsil-derived mesenchymal stem cell conditioned medium (T-MSC CM) on glucocorticoid signal transduction. In this study, we investigated the therapeutic efficacy of T-MSCs in a mouse model of exogenous Cushing's syndrome.

Cystitis glandularis (CG) is a chronic hyperplastic disorder of the bladder, and the available clinical drug therapy is insufficient currently. Glycyrrhetinic acid (GA), a bioactive compound extracted from the roots of Glycyrrhiza glabra, is found with beneficial actions, including anti-inflammatory and anti-oxidative effects. We previously reported that GA relieves CG symptoms in animal model, implying the potential application of GA to treat CG.

Atopic dermatitis (AD) is a chronic inflammatory skin condition characterized by dry skin, severe itching, redness, and inflammation. Its complex etiology, involving genetic, immunological, and environmental factors, necessitates innovative therapeutic approaches. This study investigates nanostructured lipid carriers (NLCs) formulated with traditional fermented coconut (Cocos nucifera L.
