Iron overload promotes the progression of MLL-AF9 induced acute myeloid leukemia by upregulation of FOS.

Systemic iron overload is a common clinical challenge leading to significantly serious complications in patients with acute myeloid leukemia (AML), which affects both the quality of life and the overall survival of patients. Symptoms can be relieved after iron chelation therapy in clinical practice. However, the roles and mechanisms of iron overload on the initiation and progression of leukemia remain elusive.

Teaching Dental Drawings for Freshman Dental Students and Its Correlation with Manual Dexterity.

Objective: To assess whether the implementation of teeth drawing exercises in a dental anatomy course improves first-year (D1) dental students' understanding of tooth morphology, their dexterity, and their clinical skills compared with D1s who did not participate in the drawing exercises.

Methods: In 2020, a "Teeth Drawing Module" was implemented within the D1 dental anatomy curriculum. In this course, students learn how to draw accurate outlines of teeth.

Sox13 and M2-like leukemia-associated macrophages contribute to endogenous IL-34 caused accelerated progression of acute myeloid leukemia.

Interleukin 34 (IL-34) mainly plays physiologic and pathologic roles through the sophisticated multi-ligand signaling system, macrophage colony-stimulating factor (M-CSF, CSF-1)/IL-34-CSF-1R axis, which exhibits functional redundancy, tissue-restriction and diversity. This axis is vital for the survival, differentiation and function of monocytic lineage cells and plays pathologic roles in a broad range of diseases. However, the role of IL-34 in leukemia has not been established.

CBCT analysis of crestal soft tissue thickness before implant placement and its relationship with cortical bone thickness.

Background: The importance of crestal soft tissue thickness and its influence in peri-implant tissue health has been evaluated in few clinical studies. Cone beam computed tomography imaging offers a unique opportunity to investigate variations in crestal soft tissue thickness. The aim of this retrospective study was to evaluate the possible correlation between crestal soft tissue thickness and hard tissue measurements on CBCT images, and to compare crestal soft tissue thickness among different patients and edentulous site groups.

Fbxw11 impairs the repopulation capacity of hematopoietic stem/progenitor cells.

Background: The ubiquitin-proteasome system plays important roles in maintaining the self-renewal and differentiation of stem and progenitor cells through highly ordered degradation of cellular proteins. Fbxw11, an E3 ligase, participates in many important biological processes by targeting a broad range of proteins. However, its roles in hematopoietic stem/progenitor cells (HSPCs) have not been established.

DDIT4 mediates the proliferation-promotive effect of IL-34 in human monocytic leukemia cells.

IL-34 is involved in a broad range of cancer. that IL-34 promoted the proliferation and colony formation of human acute monocytic leukemia (AMoL) cells. However, the mechanism has not been elucidated.

Loss of IRF7 accelerates acute myeloid leukemia progression and induces VCAM1-VLA-4 mediated intracerebral invasion.

Interferon regulatory factor 7 (IRF7) is widely studied in inflammatory models. Its effects on malignant progression have been documented mainly from the perspective of the microenvironment. However, its role in leukemia has not been established.

poly(I:C) synergizes with proteasome inhibitors to induce apoptosis in cervical cancer cells.

Cervical cancer is one of the most common malignancies in women, with a poor survival rate. Thus, there is a need to define effective combination strategies to improve therapy. In this study, we report that dsRNA poly(I:C) up-regulated the expression of IFNβ and apoptosis-associated genes in cervical cancer cells, activating both intrinsic and extrinsic apoptotic pathways, and eventually inducing cell death.

Subgingival microbiome in Chinese patients with generalized aggressive periodontitis compared to healthy controls.

Objective: The aim of the study was to profile the subgingival microbiome of Chinese adults with generalized aggressive periodontitis (GAgP) using human oral microbe identification microarray (HOMIM), and to compare the results with matched periodontal healthy controls.

Design: 15 subjects with GAgP and 15 age- and gender- matched periodontal healthy controls were included. Subgingival plaque samples were collected from the deepest pockets of patients with GAgP and matched sites in controls and then analyzed by 16S rRNA-based microarrays.

Satisfaction among early and mid-career dentists in a metropolitan dental hospital in China.

A growing body of research has examined career satisfaction among dentists using a standardized instrument, dentist satisfaction survey (DSS). This project examined career satisfaction of early to mid-career dentists in China, a population whose career satisfaction, heretofore, has not been studied. This is an especially critical time to examine career satisfaction because of health care reform measures being implemented in China.
