Reconstruction with double pedicel fibular graft and ankle arthrodesis for aggressive chondroblastoma in the distal tibia

Background Aggressive chondroblastoma of the distal tibia is rare, and below-knee amputation had been the standard surgical procedure. Case presentation We reported an additional case and reviewed the existing literature. A 20-year-old man with a 2-month history of right ankle pain and swelling underwent distal tibia wide resection, double pedicle fibular, autogenous iliac bone ...

Optimal watermark embedding combining spread spectrum and quantization

This paper presents an optimal watermark embedding method combining spread spectrum and quantization. In the method, the host signal vector is quantized to embed a multiple-bit watermark, and meanwhile, the quantized signal is made to locate in the detectable region defined in the context of spread spectrum watermarking. Under the two constraints, the optimal watermarked signal is ...

A Rapid and Convenient Method for Fluorescence Analysis of In Vitro Cultivated Metacestode Vesicles from Echinococcus multilocularis

We here describe a convenient method for preparation, fixation and fluorescence analysis of in vitro cultivated metacestode vesicles from E. multilocularis. Parasite materials could be prepared in one hour, did not need to be sectioned, and were subsequently utilized for further whole-mount staining assays directly. Using these preparations, in combination with conventional ...

Recent advances in the role of toll-like receptors and TLR agonists in immunotherapy for human glioma

, Toll-like receptor. COMPLIANCE WITH ETHICS GUIDELINES Shuanglin Deng, Shan Zhu, Yuan Qiao, Yongjun Liu, Wei Chen, Gang Zhao, and Jingtao Chen declare that they have no conflict of interest. This

MEMS-Based Handheld Fourier Domain Doppler Optical Coherence Tomography for Intraoperative Microvascular Anastomosis Imaging

Purpose To demonstrate the feasibility of a miniature handheld optical coherence tomography (OCT) imager for real time intraoperative vascular patency evaluation in the setting of super-microsurgical vessel anastomosis. Methods A novel handheld imager Fourier domain Doppler optical coherence tomography based on a 1.3-µm central wavelength swept source for extravascular imaging was ...

Mouse Models of Intracerebral Hemorrhage in Ventricle, Cortex, and Hippocampus by Injections of Autologous Blood or Collagenase

Intracerebral hemorrhage (ICH) is a devastating condition. Existing preclinical ICH models focus largely on striatum but neglect other brain areas such as ventricle, cortex, and hippocampus. Clinically, however, hemorrhagic strokes do occur in these other brain regions. In this study, we established mouse hemorrhagic models that utilize stereotactic injections of autologous whole ...

Relationship between NaCl- and H2O2-Induced Cytosolic Ca2+ Increases in Response to Stress in Arabidopsis

Salinity is among the environmental factors that affect plant growth and development and constrain agricultural productivity. Salinity stress triggers increases in cytosolic free Ca2+ concentration ([Ca2+]i) via Ca2+ influx across the plasma membrane. Salinity stress, as well as other stresses, induces the production of reactive oxygen species (ROS). It is well established that ROS ...

Influences of DMP on the Fertilization Process and Subsequent Embryogenesis of Abalone (Haliotis diversicolor supertexta) by Gametes Exposure

Di-methyl phthalate (DMP), a typical endocrine disrupting chemical (EDC), is ubiquitously distributed in aquatic environments; yet studies regarding its impact on gametes and the resulting effects on embryogenesis in marine gastropods are relatively scarce. In this study, the influences of DMP on the gametes and subsequent developmental process of abalone (Haliotis diversicolor ...

Nuclear factor of activated T cells 5 maintained by Hotair suppression of miR-568 upregulates S100 calcium binding protein A4 to promote breast cancer metastasis

Introduction The onset of distal metastasis, which underlies the high mortality of breast cancers, warrants substantial studies to depict its molecular basis. Nuclear factor of activated T cells 5 (NFAT5) is upregulated in various malignancies and is critically involved in migration and invasion of neoplastic cells. Nevertheless, the metastasis-related events potentiated by this ...

Genetic and Cytological Analysis of a Novel Type of Low Temperature-Dependent Intrasubspecific Hybrid Weakness in Rice

Hybrid weakness (HW) is an important postzygotic isolation which occurs in both intra- and inter-specific crosses. In this study, we described a novel low temperature-dependent intrasubspecific hybrid weakness in the F1 plants derived from the cross between two indica rice varieties Taifeng A and V1134. HW plants showed growth retardation, reduced panicle number and pale green ...

NEDD9 Is a Positive Regulator of Epithelial-Mesenchymal Transition and Promotes Invasion in Aggressive Breast Cancer

Epithelial to mesenchymal transition (EMT) plays an important role in many biological processes. The latest studies revealed that aggressive breast cancer, especially the triple-negative breast cancer (TNBC) subtype was frequently associated with apparent EMT, but the mechanisms are still unclear. NEDD9/HEF1/Cas-L is a member of the Cas protein family and was identified as a ...

CELL BIOLOGY AND SIGNALING

Ikaros, a DNA-binding protein also known as Ikaros family zinc finger protein 1 (IKZF1), was initially shown to function critically in hematopoietic differentiation. Deletion or mutation of Ikaros has been associated with lymphoblastic, as well as acute and chronic myelogenous leukemias demonstrating that Ikaros can act as a tumor suppressor. Ikaros is predominantly expressed in a ...

LAB-STEM CELLS

INTRODUCTION: Recent evidence suggests that glioblastoma is driven by a subset of tumor initiating (TI) cells characterized by their capacity to form tumors in xenograft models and self-renew in vitro. These TI cells share many properties of neural stem/progenitor cells, including the expression of certain cell surface markers. With serial passage, many cells lose their capacity to ...
