Recently, new targets have been identified in head and neck squamous cell carcinomas (HNSCC) as playing key roles in tumour proliferation and metastases. The first target that has led to the approval of a molecularly based therapy in HNSCC has been the epidermal growth factor receptor (EGFR). Indeed, cetuximab, a monoclonal antibody directed against EGFR, has recently been approved in combination with radiation therapy in patients with locally advanced HNSCC, and in patients with platinum-refractory recurrent or metastatic (R/M) HNSCC. This review discusses novel targeted anticancer agents that do not exclusively target EGFR. The initial assessments of novel agents have typically been in patients with heavily pre-treated R/M HNSCC, with response rates and times to progression that are often disappointing. Evaluation of novel agents in the pre-operative 'window' setting, or as first-line therapy for R/M disease, may offer a more optimal understanding of their molecular and clinical effects.

Purpose: This study aimed to investigate the role of DNA ploidy and proliferation index in distinguishing ameloblastoma (AB) from ameloblastic carcinoma (AC).
Methods: The study included 29 ACs, 6 conventional ABs that transformed into ACs, and a control cohort of 20 conventional ABs. The demographics and clinicopathologic details of the included cases were summarised and compared.

Rapid acclimatization to baseline stimulation with a multi-canal vestibulocochlear implant.

Purpose: It is hypothesized that a vestibular implant should re-establish baseline activity of the ampullary nerves. Use of a constant baseline stimulation potentially allows encoding of bi-directional head movements, through the addition of signal modulations. Effective stimulation of the vestibular nerves depends on the ability to acclimate to this baseline signal.

Introduction: Solitary fibrous tumor (SFT) is a fibroblastic neoplasm of uncertain biological origin that is rare in the tongue.
Case Report: A 42-year-old woman presented with a painless, submucosal nodule in the tongue. Based on the clinical hypothesis of benign mesenchymal neoplasia, the lesion was excised, and the specimen was submitted for histopathological analysis.

Ethnopharmacological Relevance: Zuo Gui Wan (ZGW) is a well-known traditional Chinese medicine decoction used for approximately 400 years to treat age-related degenerative conditions, including cognitive impairment in older adults, osteoporosis, and general aging. However, the mechanism of action for ZGW remains unclear.
Aims Of The Study: This study aims to investigate the efficacy of ZGW in improving cognitive function in Alzheimer's disease (AD) animal models and to explore the underlying mechanisms, presenting a novel perspective in the field.
