Article Synopsis
- The nucleotide excision repair (NER) system helps protect against DNA damage, and deficiencies in this system can lead to increased mutations and cancer risks.
- A study analyzed 19 NER gene polymorphisms in 416 Wilms tumor cases and 936 controls from East China, finding that certain XPD polymorphisms decreased Wilms tumor risk while some XPG polymorphisms increased it.
- The research suggests that these gene variations affect nearby gene expression and emphasizes the need for further studies with larger sample sizes to validate these associations.

Objectives: This study aimed to investigate the incidence and severity of surgical fear in patients with oral and maxillofacial tumors.
Methods: The survey participants were composed of patients with oral and maxillofacial tumors, who were scheduled to undergo surgery. A general information questionnaire, the Surgical Fear Questionnaire (SFQ), the Patient Health Questionnaire (PHQ)-9, and the Generalized Anxiety Disorder (GAD)-7 score were used for the investigation.
In this paper, a Cournot-Bertrand duopoly model with market share preference is established. Assume that there is a degree of product difference between the two firms, where one firm takes the price as a decision variable and the other takes the quantity. Both firms are bounded rational, with linear cost functions and demand functions.
