Radiotherapy sensitivity is associated with the prognosis of patients with tongue squamous cell carcinoma (TSCC). In the present study, we proposed to explore the specific mechanism of interventional radiology (IR) therapy for TSCC in vitro and in vivo. TSCC cells were treated with 6 Gy IR and tumor bearing mice were treated with 20 Gy × 1 IR.

- The study investigated the link between variations in the vitamin D receptor (VDR) gene and the risk of dental caries in children under 18 years old.
- Researchers analyzed data from 79 studies, ultimately selecting 10 that focused on seven specific VDR gene variants and their relationship with tooth decay.
- Results showed that certain genotypes, particularly at the FokI and TaqI loci, were associated with an increased risk of caries, suggesting that genetic factors may influence dental health in children.
Objective: To investigate the CBCT findings of the apical anatomy of immature maxillary central incisors.
Methods: CBCT images of 100 immature maxillary central incisors in Nolla 8 and 100 immature maxillary central incisors in Nolla 9 were collected. The mesiodistal and carniocaudal diameters of the apical foramen of immature maxillary central incisors were measured by software included with CBCT, as well as the mesiodistal, carniocaudal and facioligual diameters of the apical shadow.
Background: This study aimed to evaluate spatial changes in dental arches resulting from premature loss of first primary molars and assess the necessity of a space maintainer.
Methods: We searched the electronic databases PubMed, Cochrane Library, ClinicalTrials, and EMBASE. Split-mouth studies involving unilateral premature loss of a primary first molar were included.
Background: The effectiveness of platelet concentrates in promoting root development of necrotic immature permanent teeth is unclear. The present study evaluated whether the platelet concentrate protocol was superior to the traditional blood clot protocol in regeneration therapy.
Methods: We searched Electronic databases, such as PubMed, Cochrane Library, ClinicalTrials and EMBASE.
Article Synopsis
- Colorectal adenocarcinoma (CRC) is a prevalent cancer globally, but metastatic cases often resist chemotherapy, prompting studies on treatments like semaphorin 3F (SEMA3F) that may help enhance chemosensitivity.
- This study investigates how SEMA3F affects the protein p27, which is linked to the expression of E-cadherin and integrin, to understand its role in counteracting chemotherapy resistance in CRC.
- Findings indicate that higher levels of SEMA3F improve the sensitivity of CRC cells to chemotherapy, leading to increased apoptosis and longer disease-free survival in patients with high SEMA3F expression after treatment.
Article Synopsis
- This study investigates the role of vitamin D receptor (VDR) gene variations and their interaction with environmental factors in the development of early childhood caries among Chinese children aged 3-5.
- In a sample of 549 children, researchers categorized participants into high, moderate, and caries-free risk groups and analyzed their dietary habits, oral hygiene, and specific VDR gene polymorphisms.
- Results indicated that while certain gene variations were more common in the high-risk group, they were ultimately not reliable indicators for predicting dental caries when considering environmental influences.
Influence of the Cyclooxygenase-2 Gene -765G/C and -1195G/A Polymorphisms on Development of Ischemic Stroke.

Background: Many studies have investigated the association between the cyclooxygenase-2 (COX-2) gene polymorphism and ischemic stroke. However, results of these studies still remain controversial. To better explain the association between COX-2 polymorphisms (-765G/C and -1195G/A) and ischemic stroke risk, a meta-analysis was performed.

Int J Clin Pediatr Dent
January 2014
Metallic foreign bodies are rarely found in the maxillary sinus, and usually they have a dental origin. Two main surgical app-roaches are currently used for the removal of foreign bodies in the maxillary sinus: the bone flap and the endoscopic sinus tech-niques. However, the treatment is not only surgical removal.

Objective: To evaluate the genotypic diversity of Streptococcus sobrinus (Ss) between children suffering with severe early childhood caries (S-ECC) and caries-free children by arbitrarily primed-polymerase chain reaction (AP-PCR).
Methods: A total of 178 children aged from 42 to 54 months were recruited from 14 urban kindergartens. The S-ECC group contained 87 children with more than 5 decayed teeth, and the control group was composed of 91 caries-free children.
