Tooth eruption is the process whereby the developing tooth moves to its functional position in the occlusal plane and it occurs concomitantly with formation of the tooth root, which is a critical component of the tooth anchored to surrounding alveolar bone through the periodontal ligament. Post-eruptive tooth movement ensues that once occlusion is achieved, the teeth maintain their alignment within the alveolar bone to facilitate proper bite function through periodontium remodelling. Tooth overeruption presents a clinically significant issue, yet the precise mechanisms by which alterations in occlusal forces are translated into periodontal remodelling remain largely unexplored.

The structure and absolute configuration of compound were assigned by extensive analysis of MS, NMR data, and quantum-chemical calculations including electronic circular dichroism (ECD) and calculated C NMR-DP4+ analysis. Bioassay results showed that compound displayed moderate inhibition on NO production in RAW 264.
View Article and Find Full Text PDFFms-like tyrosine kinase 3 (FLT3) is frequently mutated in haematological malignancies. Although canonical FLT3 mutations including internal tandem duplications (ITDs) and tyrosine kinase domains (TKDs) have been extensively studied, little is known about the clinical significance of non-canonical FLT3 mutations. Here, we first profiled the spectrum of FLT3 mutations in 869 consecutively newly diagnosed acute myeloid leukaemia (AML), myelodysplastic syndrome and acute lymphoblastic leukaemia patients.

Persistent vulnerability to relapse is a major challenge in the treatment of this subtype of patients. Venetoclax is a BCL-2 selective inhibitor.

Wntless, an exclusive chaperone protein for the exocytotis of Wnt ligands, was identified in 2006. In the last decade, the molecular biological studies of Wntless and its genetic studies in human and mice have highlighted the importance of this protein in mineralised tissues, including bone, cartilage and teeth.

At present, treatment with weekly cisplatin plus ionizing radiation (IR) therapy is the standard regimen for cervical cancer, especially for locally advanced cervical cancer. The purpose of this study is to determine whether FEN1 inhibitors could enhance the therapeutic effect of IR therapy.

In mammals, FEN1 functional sites variation is related to cancer and chronic inflammation, and supports the role of FEN1 as a tumor suppressor. However, FEN1 is overexpressed in multiple types of cancer cells and is associated with drug resistance, supporting its role as an oncogene.

Objective: To detect and analyze the mutation status of FANCJ gene in adult AML patients, so as to provide the basis for studying the mechanism of FANCJ driven AML and guiding the preventim and treatment of deseese.
Methods: The cDNAs were extracted and transeripted from bone marrow cells and normal skin cells in 222 newly diagnosed AML patients. The primers were designed for FANCJ gene coding region, the mutations of FANCJ gene coding region in AML patients as well as the mutations of FANCJ gene in mucous membrane epethelia in patients were detected by PCR and sanger seguencing; the evolutionary conservation of FANCJ mutation in different organisms was analyzed by NCBI Blast online bioinformaties software.
Objective: The optimal treatment for chronic type B dissection remains controversial. This study reports early and midterm results of thoracic endovascular aortic repair for chronic type B aortic dissection.
Methods: From June 2001 to September 2007, a total of 84 patients with chronic type B aortic dissection underwent thoracic endovascular aortic repair.
Difference between arch diameter and true lumen diameter in the descending aorta was studied in patients with type B aortic dissection. The diameters of the aortic arch (Proximal ) and mid-descending aorta (Distal ) were measured on computer tomography angiography (CTA) in 20 healthy adults. Forty-two patients with type B aortic dissection who underwent endovascular repair were divided into two groups: an acute group (23 patients) and a chronic group (19 patients).

Methods: From June 2001 to May 2005, 63 patients with acute type B aortic dissection underwent stent graft implantation. The study included 59 men and 4 women with an average age of 50.
Background: The purpose of this study is to evaluate the feasibility and safety of stent graft in the treatment of aortic dissection and penetrating aortic ulcer.
Methods: From June 2001 to April 2004, 25 patients with aortic dissection and 5 patients with penetrating aortic ulcer received stent-graft implantation. Within this group were 24 male and 6 female patients, with an average age of 52.
Objective: To evaluate the effect and safety of transfemoral stent-graft placement in combination with transesophageal echocardiography (TEE) in treating DeBakey IIIb aortic dissecting aneurysm.
Methods: Eight male patients [mean age (55.8 +/- 10.
