Aim: To investigate the effects of SKA3 on cell proliferation and metastasis in non-small-cell lung cancer (NSCLC) and its underlying mechanism. Methods: Immunohistochemistry was employed to analyze the expression of SKA3 in NSCLC. CCK-8 assay, EdU assay, Transwell assay and flow cytometry analysis were employed to assess cell proliferation, metastatic potential and apoptosis in vitro, respectively. A lung metastasis model was used to evaluate metastasis of NSCLC cells in vivo. A luciferase reporter gene assay was conducted to verify the targeting relationship. Results: SKA3 exhibited high expression in NSCLC tissues and cells. Overexpression of SKA3 remarkably accelerated cell proliferation and metastasis and suppressed apoptosis of NSCLC cells and promoted lung metastasis in a mouse model. miR-128-3p repressed SKA3 expression by targeting it. Conclusion: miR-128-3p inhibited the progression of NSCLC through targeting SKA3.

This paper is aimed at investigating the efficacy of combining internal fixation using prefabricated rib-locking titanium plate with ultrasound-guided thoracic paravertebral nerve blockade in treating multiple rib fractures among the elderly.Retrospective analysis of 221 elderly patients with multiple rib fractures treated from February 2016 to November 2020. According to whether surgery was performed, they were divided into the plate-blockage combination group (surgical group, 102 cases) and conservative treatment group (non-surgical group, 119 cases). The surgical group consisted of 58 males and 44 females aged from 60 to 85 years old, with an average of (67.2±3.6 ) years old, who suffered from 3 to 12 rib fractures with an average of (5.3±2.1) fractures. The non-surgical group consisted of 66 males and 53 females aged from 60 to 84 years old with an average of (66.8±3.2) years old, who suffered from 2 to 11 rib fractures with an average of(6.1±2.3) fractures. The clinical data, efficacies observed, and complications associated with both groups were compared and analyzed.There was no significant difference in preoperative clinical data between two groups (For elderly patients with severe multiple rib fractures, the proposed plate-blockade combination can timely and effectively relieve pain, restore thoracic stability, shorten hospital stay, and reduce the incidence of complications such as pulmonary infections and acute respiratory distress syndrome(ARDS) compared with non-surgical treatments. Prefabricated rib-locking titanium plates have proved to demonstrate high clinical efficacy in treating multiple rib fractures among the elderly.

This article investigates the maximum spreading of ferrofluid droplets impacting on a hydrophobic surface under nonuniform magnetic fields. A generalized model for scaling the maximum spreading is developed. It is observed that, if the magnetic field strength is zero, a ferrofluid droplet not only demonstrates similar spreading dynamics as the water droplet but also obeys the same scaling law for the maximum spreading factor. Therefore, this article emphasizes the effects of magnetic field strength. In this regard, a dimensionless parameter (

In this paper, the dynamical mechanism and a general deformation law of a ferrofluid droplet suspended between the air and a liquid substrate under the action of the applied vertical uniform magnetic field are investigated by a numerical model. A generalized conservative phase-field simplified multiphase lattice Boltzmann model is adopted to solve the flow field and phase field, which has a good ability to simulate the problems of ternary fluid flows with large density ratios. Subsequently, the Maxwell equation of static magnetic field is used to solve the magnetic field using a self-correcting scheme. We used this model to numerically study the dynamic evolvement process of ferrofluid droplets placed between the air and a liquid substrate, which are exposed in a vertical uniform magnetic field. Some typical characteristics are employed to characterize the droplet shape, and it is found that the aspect ratio, the elongated velocity, and the height of the mass center of the ferrofluid droplet are related to the magnetic Bond number. Furthermore, the numerical results obtained with the model are in good agreement with the experimental results available in the literature. Finally, the quantitative power law relation between the magnetic Bond number and the aspect ratio of ferrofluid droplets is obtained by using the method of scaling law, which provides a theoretical basis for the study of the deformation mechanism and the universal laws of a ferrofluid droplet placed between the air and a liquid substrate under the action of the vertical uniform magnetic fields with different intensities.

Gastric cancer (GC) is a major tumor throughout the world with remaining high morbidity and mortality. The aim is to generate a gene model to assess the prognoses risk of patients with GC.Gene expression profiling of gastric cancer patients, GSE62254 (300 samples) and GSE26253 (432 samples), was downloaded from Gene Expression Omnibus (GEO) database. Univariate survival analysis and LASSO (Least Absolute Shrinkage and Selectionator operator) (1000 iterations) of differentially expressed genes in GSE62254 was assessed using survival and glmnet in R package, respectively. Kaplan-Meier analysis on the clustering algorithm from each regression model was performed to calculate the influence to the prognosis. Random samples in GSE26253 were analyzed in multivariate and univariate survival analysis for one thousand times to calculate statistical stability of each regression model.A total of 854 Genes were identified differentially expressed in GSE62254, among which 367 Genes were found influencing the prognoses. Six gene clusters were selected with good stability. Hereinto, five or more genes in 11-Gene model, TRPC1, SGCE, TNFRSF11A, LRRN1, HLF, CYS1, PPP1R14A, NOV, NBEA, CES1 and RGN, was available to evaluate the prognostic risk of GC patients in GSE26253 (P = 0.00445). The validity and reliability was validated.In conclusion, we successfully generated a stable 5-Gene model, which could be utilized to predict prognosis of GC patients and would contribute to postoperational treatment and follow-up strategies.

Non-small lung cancer (NSLC) is one of the leading causes of cancer-related deaths world over. Excempting operable cases the treatments for NSCLC mainly include chemotherapy and radiotherapy. However, the survival rate for NSCLC is still far from satsifactory. Moreover, chemotherapy has lot of associated side effects. Therefore, there is an urgent need to look for novel and more viable treatment options. Against this background, the present study was designed to evaluate the anticancer activity of α-Bisabolol against NSCLC.Cell viability was assessed by MTT assay. Apoptosis was determined by DAPI and annexin V/propidium iodide (PI) staining. Mitochondrial membrane potential (MMP) and cell cycle analysis were determined by flow cytometry. Cell migration was investigated by wound healing assay and protein expression was evaluated by western blotting.α-Bisabolol exerted significant anticancer activity on A549 NSCLC cells with IC50 of 15 μM. The anticancer effects of α-Bisabolol were found to be due to G2/M cell cycle arrest and mitochondrial apoptosis. α-Bisabolol also inhibited cell migration of A549 cells dose-dependently. Moreover, the results showed that α-Bisabolol could inhibit the PI3K/AKT signalling pathway in a dose-dependent manner. The results of the present study indicate that α-Bisabolol exerted selective anticancer effects on A549 cells via induction of cell cycle arrest, mitochondrial apoptosis and inhibition of PI3K/Akt signalling pathways.This molecule showed promising anticancer features and could be developed as a potent lead candidate for the management and treatment of NSCLC.

This article presents a detailed experimental analysis along with numerical simulations to provide the information about shape evolutions and mechanism of actuation and amalgamation of the ferrofluid droplets deposited on a hydrophobic surface by moving a permanent magnet. To validate the numerical methods used in this article, a benchmark phenomenon of a sessile droplet spreading under the effect of a non-uniform magnetic field is first simulated, and the results are compared with available experimental observations. To further ensure the accuracy of experimental and numerical techniques and to understand the wetting properties and spreading behavior of non-stationary ferrofluid droplets, a prototype demonstration of the merging droplets on a hydrophobic solid surface in the presence of a permanent magnet is designed. It is observed that for hydrophobic surfaces, the merging droplets entrap an air bubble at the time of first contact. Moreover, the physics behind the transient variations of droplet morphology and the effect of the state-of-the-art parameters on droplet actuation are also discussed. The force evaluation, energy variations, velocity contours, and velocity vectors of the moving droplet are provided to understand the internal behavior of droplet mobility. Experiments are performed several times with different speeds of moving a magnet to find the critical velocity when the droplet fails to follow the magnet motion. While doing so, we encounter an anomalous phenomenon of thread formation and daughter droplet generation at the receding end of the sliding droplet. A phase diagram is also provided in the end, which describes different regions of the sliding phenomenon. [ABSTRACT FROM AUTHOR]
