Effect of CO Concentration on the Performance of Polymer-Enhanced Foam at the Steam Front.

This study examines the impact of CO concentration on the stability and plugging performance of polymer-enhanced foam (PEF) under high-temperature and high-pressure conditions representative of the steam front in heavy oil reservoirs. Bulk foam experiments were conducted to analyze the foam performance, interfacial properties, and rheological behavior of CHSB surfactant and Z364 polymer in different CO and N gas environments. Additionally, core flooding experiments were performed to investigate the plugging performance of PEF in porous media and the factors influencing it.

Study on the Control of Steam Front Mobility in High-Temperature and High-Salinity Conditions Using Polymer-Enhanced Foam.

This study investigated the enhancing effects of the temperature-resistant polymer Poly(ethylene-co-N-methylbutenoyl carboxylate-co-styrenesulfonate-co-pyrrolidone) (hereinafter referred to as Z364) on the performance of cocamidopropyl hydroxy sulfobetaine (CHSB) foam under high-temperature and high-salinity conditions. The potential of this enhanced foam system for mobility control during heavy oil thermal recovery processes was also evaluated. Through a series of experiments, including foam stability tests, surface tension measurements, rheological assessments, and parallel core flooding experiments, we systematically analyzed the interaction between the Z364 polymer and CHSB surfactant on foam performance.

SKA3 Promotes Cell Growth in Breast Cancer by Inhibiting PLK-1 Protein Degradation.

Breast cancer (Bca) remains the most common form of malignancy affecting females in China, leading to significant reductions in the mental and physical health of those with this condition. While spindle and kinetochore associated complex subunit 3 (SKA3) is known to be linked with cervical cancer progression, whether it is similarly associated with Bca progression remains unknown. Using shRNA, we specifically knocked down the expression of SKA3 in Bca cell lines and then assessed the resultant changes in cell proliferation using CCK-8 and colony formation assays.

MiR-16-5p inhibits breast cancer by reducing AKT3 to restrain NF-κB pathway.

Breast cancer endangers the life of women and has become the major cause of deaths among them. MiRNAs are found to exert a regulatory effect on the migration, proliferation and apoptosis of breast cancer cells. This research aims at investigating the miR-16-5p expression and its effect on the pathogenesis of breast cancer.

APC gene promoter aberrant methylation in serum as a biomarker for breast cancer diagnosis: A meta-analysis.

Background: The aim of this study was to evaluate the clinical efficacy of APC gene promoter methylation in serum as a biomarker for breast cancer (BC) diagnosis.

Methods: Two reviewers systematically searched online resources to identify the publications relevant to APC gene promoter methylation and BC. The data of true positive, false positive, false negative, and true negative were extracted from each included study and pooled for diagnostic sensitivity, specificity, and summary receiver operating characteristic curve.

[Study on effect of Xiaoaiping in enhancing efficacy of neoadjuvant chemotherapy for breast cancer and its mechanism].

Traditional Chinese medicine (TCM) Xiaoaiping shows a pharmacological activity in treatment of breast cancer. Although neoadjuvant chemotherapy has been more and more widely used in treatment of breast cancer in recent years, no report has been made about the clinical efficacy and mechanism of the combined application of neoadjuvant chemotherapy and Xiaoaiping in treatment of breast cancer. In this study, 66 patients with breast cancer were selected and divided into the control group and the treatment group evenly with the random number table method.

Association between FOXP3 promoter polymorphisms and cancer risk: A meta-analysis.

Epidemiological studies have been conducted to investigate the association between the FOXP3 promoter polymorphisms, rs3761549 and rs3761548, and the risk of cancer. However, the results from these studies have been controversial. In order to obtain a more precise conclusion of this association, the present meta-analysis was performed.
