Long Fiber Spray-up Molding (LFSM) deviates from the conventional approach in liquid composite molding (LCM) processes by utilizing extremely long chopped strands of fibers as the primary reinforcement material in its fabrication process. In LFSM, chopped fibers are impregnated with resin that is sprayed vertically downwards before reaching the mold surface. The spraying mechanism is mounted on an actuator, which is capable of spraying freely in any specified pattern or direction.

Recent advances in nanomaterials technology create the new possibility to fabricate high performance sensors. However, there has been limitations in terms of multivariate measurable and interoperable sensors. In this study, we fabricated an interoperable silver nanoparticle sensor fabricated by an aerodynamically focused nanomaterial (AFN) printing system which is a direct printing technique for inorganic nanomaterials onto a flexible substrate.

Microsatellite instability (MSI) is closely related to the prognosis and therapy response of colon cancer. Colon cancer patients with MSI show resistance to 5-Fluorouracil (5-FU) but sensitivity to immunosuppressive checkpoint inhibitors (ICIs). The relevant mechanism behind the opposite response remains unclear.

The purpose of this study was to investigate the impacts of the formulation parameters on the pharmacokinetics and bioequivalence of risperidone orodispersible film (ODF) using physiologically based pharmacokinetic model. The pharmacokinetic profiles of two risperidone ODFs, which exhibit different in vitro dissolution, were examined in Beagle dogs after supralingual administration. Subsequently, a physiologically based pharmacokinetic (PBPK) model was constructed to evaluate the in vivo performance of risperidone ODF.

Structural colors that can be changed dynamically, using either plasmonic nanostructures or photonic crystals, are rapidly emerging research areas for stretchable sensors. Despite the wide applications of various techniques to achieve strain-responsive structural colors, important factors in the feasibility of strain sensors-such as their sensing mechanism, stability, and reproducibility-have not yet been explored. Here, we introduce a stretchable, diffractive, color-based wireless strain sensor that can measure strain using the entire visible spectrum, based on an array of cone-shaped nanostructures on the surface of an elastomeric substrate.

Autophagy plays a key role in colorectal cancer (CRC) development and reduces the sensitivity of CRC cells to treatment. The present study reported a novel tumor‑suppressive role for autophagy, which was demonstrated to be regulated through the novel oncogene neurotrophin‑4 (NTF4). NTF4 was significantly overexpressed in tumor tissue compared with non‑tumor mucosa, and the upregulation of NTF4 in CRC was associated with poor overall survival and advanced TNM stage.

Interleukin (IL)‑1β is a member of the IL‑1 family of proteins. IL‑1 receptor antagonist (IL‑1RA) is an agent that binds to the IL‑1 receptor, preventing IL‑1 from transmitting signals to cells. The present study aimed to identify the role of the IL‑1β/1RA axis in epithelial‑mesenchymal transition (EMT), cell invasion, migration, proliferation and clone formation in colorectal cancer (CRC) and to determine its underlying mechanisms of action.

Interleukin‑17F (IL‑17F) is a member of the IL‑17 family of proteins. Previous studies concerning IL‑17F have mainly focused on its proinflammatory responses, whereas the present study explored its role as an oncogene in colorectal cancer (CRC). The present study investigated the expression of IL‑17F in 69 patients with CRC.

This study aimed to find risk factors for colon cancer progression with bioinformatics methods, and validated by clinical patients. Differentially expressed genes (DEGs) between colon cancer tissues and normal colon tissues were extracted from The Cancer Genome Atlas (TCGA) database using R software, amounted to 8,051. DEGs between pathologic stage I+II and stage III+IV amounted to 373, and were compared with DEGs of cancer/normal analyzed above to get the intersection of both.

Our previous study has demonstrated that knockdown of Grainyhead-like 2(GRHL2) in colorectal cancer (CRC) cells inhibited cell proliferation by targeting ZEB1. This study aimed at researching whether knockdown of GRHL2 promoted CRC progression and metastasis via inducing epithelial-mesenchymal transition (EMT). GRHL2-upregulated SW-620/GRHL2+ and GRHL2-knockdown HCT116/GRHL2-KD, HT29/GRHL2-KD cells and their control cells were generated.

Background: Osteopontin (OPN) is highly expressed in colorectal cancer (CRC) and is associated with disease progression in vivo. High levels of OPN have been demonstrated to predict low survival rates in CRC. Autophagy is a process of self-digestion, which is thought to play a significant role in carcinogenesis.

Background And Objective: Transcriptional factor E2A is crucial for the normal development and differentiation of B and T lymphocytes. Dysregulation of E2A leads to leukemia and tumorigenesis of some solid tumors. The expression and clinical significance of E2A as well as its role in colorectal cancer (CRC) are still unknown.

Article Synopsis
  • The study aimed to compare the effectiveness of extralevator abdominoperineal resection (EAPR) against conventional abdominoperineal resection (APR) in terms of circumferential resection margin (CRM) involvement, intraoperative perforation (IOP), and local recurrence (LR) rates for rectal cancer.
  • A meta-analysis of six studies involving 881 patients found that EAPR resulted in significantly lower rates of CRM involvement (36% lower) and IOP (69% lower) compared to APR, and also a reduced LR rate (73% lower) in a subset of studies.
  • The results suggest that EAPR provides better outcomes regarding CRM involvement, IOP, and LR rates, indicating its

Background: E2A gene, which encodes two basic helix-loop-helix (bHLH) transcription factors E12 and E47, has been identified as regulator of B lymphoid hematopoiesis and suppressor of lymphoma. E47 protein was found to decrease E-cadherin expression and induce epithelial-mesenchymal transition (EMT). However, the role of E2A in colorectal cancer (CRC) metastasis is still elusive.
