Adsorption of Polyetheramine-230 on Expansive Clay and Structure Properties Investigation.

Polyetheramine (PEA) is a swelling inhibitor used to address engineering challenges arising from the interaction between montmorillonite (Mt) and water. This study comprehensively investigates the adsorption characteristics of PEA on three representative expansive clay samples: Na-Mt, Ca-Mt, and engineered expansive soil. Additionally, the desorption of exchangeable ions is examined.

Influence of different infill materials on the performance of geocell-reinforced cohesive soil beds.

This paper presents a comprehensive study on the numerical and parametric study of geocell-reinforced cohesive soil beds, focusing on different infill materials. The numerical calculations were validated against model test results using FLAC software. Subsequently, the verified model was expanded to the geocell-reinforced cohesive soil beds.

Experimental study on the engineering properties of expansive soil treated with Al.

This paper investigates the stabilization of expansive soil with hydroxy-aluminium (Al) with Al/soil ratios of 0.10, 0.14, 0.

Endodontic management of the maxillary first molar with special root canals: A case report and review of the literature.

Background: As the complex anatomy of maxillary first molars is one of the major challenges in endodontic therapy, knowledge of the complicated root canal anatomy and configuration is crucial to ensure the success of endodontic treatment and prognosis. This article presents an endodontically managed left maxillary first molar with an unusual palatal root morphology. The available literature on the anatomic variation of maxillary first molars is also reviewed.

Transcription of HOTAIR is regulated by RhoC-MRTF-A-SRF signaling pathway in human breast cancer cells.

HOTAIR is a long non-coding RNA highly expressed in cancer tissues and is a negative prognostic factor, whereas the mechanism by which HOTAIR expression is upregulated in cancers remains elusive. In the present study, the regulation of HOTAIR transcription was investigated in breast cancer cells MCF7 and T47D. We found that, when the RhoC-ROCK signaling was disturbed by specific siRNAs or chemical inhibitors, the expression of HOTAIR would be down-regulated.

Transcriptional factors p300 and MRTF-A synergistically enhance the expression of migration-related genes in MCF-7 breast cancer cells.

The transcriptional coactivator p300 is highly expressed in breast cancer tissues. MRTF-A is a transcription factor governed by the Rho-GTPase-actin signaling pathway. The purpose of this study was to explore the role of p300 in breast cancer metastasis.

[The application of external fixator in CT guided ¹²⁵I Seeds implantation to treat head and neck neoplasms].

Objective: To investigate the effect of external fixator in posture fixation during the interstitial of ¹²⁵I seeds implantation for head and neck cancer under CT guidance.

Methods: 20 cases of head and neck cancer patients with CT guided radioactive ¹²⁵I particle implantation were enrolled. 10 patients of group A for external fixator, the other 10 of group B used conventional bind belt.
