Automated recognition of mouse behaviors is crucial in studying psychiatric and neurologic diseases. To achieve this objective, it is very important to analyze the temporal dynamics of mouse behaviors. In particular, the change between mouse neighboring actions is swift in a short period. In this paper, we develop and implement a novel hidden Markov model (HMM) algorithm to describe the temporal characteristics of mouse behaviors. In particular, we here propose a hybrid deep learning architecture, where the first unsupervised layer relies on an advanced spatial-temporal segment Fisher vector encoding both visual and contextual features. Subsequent supervised layers based on our segment aggregate network are trained to estimate the state-dependent observation probabilities of the HMM. The proposed architecture shows the ability to discriminate between visually similar behaviors and results in high recognition rates with the strength of processing imbalanced mouse behavior datasets. Finally, we evaluate our approach using JHuang's and our own datasets, and the results show that our method outperforms other state-of-the-art approaches.

Background: The nod-like receptor family pyrin domain-containing 3 (NLRP3) has been implicated in various skin diseases. However, its role in mediating 2, 4-dinitrofluorobenzene (DNFB)-induced chronic itch remains unclear.
Methods: Widetype () and deletion ( )mice, the expression of transient receptor potential (TRP) ankyrin 1 (TRPA1) inhibitor or recombinant mice interleukin-18 (IL-18) were used to establish and evaluate the severity of DNFB-mediated chronic itch.

Background: Neuropathic pain (NP) is a prevalent chronic condition frequently accompanied by adverse emotional states. Previous research has demonstrated the clinical efficacy of electroacupuncture (EA) in mitigating neuropathic pain and its associated mood disorders. Recent studies have underscored a correlation between gut microbiota and both NP and negative emotional states.

Background: In clinical practice, imiquimod is used to treat Human Papillomavirus (HPV)-related lesions, such as condyloma and Cervical Intraepithelial Neoplasia (CIN). Metronidazole is the most commonly prescribed antibiotic for bacterial vaginosis. The study developed biodegradable imiquimod- and metronidazole-loaded nanofibrous mats and assessed their effectiveness for the topical treatment of cervical cancer, a type of HPV-related lesion.

Purpose: Gastrostomy is the commonly used enteral feeding technology. The clinical risks caused by tube dislodgement and peristomal site infection are the common complications before complete tract maturation after gastrostomy. However, there is currently no relevant research to promote gastrostomy wound treatment and tract maturation.
