Endoscopic Evaluation of Neoadjuvant Chemotherapeutic Efficacy in Gastric Cancer before Gastrectomy Might be as Useful as Histological Assessment after Gastrectomy

Conclusions: Most endoscopic responders showed JCGC histological responses. Evaluation of neoadjuvant chemotherapeutic efficacy by endoscopy in gastric cancer may be useful before gastrectomy. As this was a retrospective study, further investigations are required. The protocol was approved by the ethics review committee at Osaka Medical College (No. 2422) and was registered in the University Hospital Medical Information Network Clinical Trial Registry (UMIN000033088).Digestion

PAK5 was primitively detected in the cerebrum and accelerated the filopodia formation in neurocytes. It can reverse the effect of Rho and adjust its activity to mediate maintenance and development of nerve axon by ...

In this report, 7-ethyl-10-hydroxycamptothecin (SN-38) coated graphene oxide synthesized (SN-rGO) effectively and are characterized using various analytical methods. The hydroxyl and carbonyl gatherings of oxidized SN38 will in general ingest onto GO by means of hydrogen bond arrangement with their leftover oxygen functionalities and offers steadiness to SN38. The morphological analyses showed the foldable fields of SN38-rGO NPs with acquire transparency, thin sheets and the crumpled structures. Further the photothermal efficiency and cytotoxicity of the SN-rGO were examined by MTT assay using two NCI-N87 and SGC-791 gastr...

In this study, calcium alginate (CA) microspheres, a pH responsive and biodegradable material, were prepared by a modified double emulsion technology and used as the AST encapsulation agent. Experimental results showed that the microparticles formed had a good degree of roundness, dispersity, encapsulation efficiency, and pH responsiveness. Cellular studies demonstrated that AST encapsulated in CA could inhibit hepatoma cells (HepG2 cell line) but it has relatively small or no impact on control hepatocytes (THLE-2 cell line). Furthermore, investigation of the underlying mechanism indicated that recovery of disorder of gluc...

Authors: Sert OZ, Gulmez S, Uzun O, Bozkurt H, Gunes OH Abstract Digestive system carcinomas containing a neuroendocrine and an exocrine component are classified as mixed adenoneuroendocrine carcinomas(manec), as one of the component represents at least 30% of the whole lesion. We herein aim to contribute to literature by presenting our rare case of gastric manec. A 58-year-old male patient had a 3 cm mass placed in the antrum in his gastroscopy. The biopsy result was signet ring cell carcinoma. After that total gastrectomy with d2 lymph node dissection and roux-en-y oesophagojejunostomy was performed. The histopat...

Authors: Venugopal N, Yeh J, Kodeboyina SK, Lee TJ, Sharma S, Patel N, Sharma A Abstract The discovery of lung carcinoma subtype-specific gene expression changes has the potential to elucidate the molecular differences and provide personalized therapeutic targets for these pathologies. The aim of the present study was to characterize the genetic profiles of the early stages (IA/IB) of two non-small cell lung cancer subtypes, adenocarcinoma (AD) and squamous cell carcinoma (SC). RNA-Seq gene expression data from The Cancer Genome Atlas was analyzed to compare the gene expression differences between AD and SC. The ge...

Abstract CHFR is a tumor suppressor that not only recognizes poly(ADP-ribosylation) (PARylation) signals at the sites of DNA damage but also is downregulated in many types of cancer. However, the underlying mechanism linking its role in PARylation-mediated DNA damage repair and tumor suppression is unclear. Here, we examined a panel of gastric cancer cell lines as well as primary tissue samples from gastric cancer patients, and found that CHFR expression was silenced by DNA hypermethylation in gastric cancer including 38.46% of primary gastric cancers. DNMT1 was associated with aberrant methylation of CHFR, and th...

Conclusion Dyspepsia as a parameter to investigate gastric or oesophageal cancer contributes significantly to the growth in number of 2-week-wait referrals at a time when endoscopy units battle to meet demand. Our data show patients with uncomplicated dyspepsia rarely have gastric or oesophageal cancer and should not undergo endoscopies under the urgent 2-week-wait pathway.

Comparison of detection rates of esophageal squamous cell carcinoma (ESCC) and gastric adenocarcinoma (GA) according to age groups and ALDH2 genotype between the 1993 ‐2007 screening period and the 2008‐2018 screening period in Japanese alcohol‐dependent men. The detection rates for ESCC and GA were consistently lower during the 2008‐2018 study period than during the 1993‐2007 study period regardless of age groups and ALDH2 genotype. AbstractBackgroundEsophageal squamous cell carcinoma (ESCC), head and neck SCC (HNSCC), and gastric adenocarcinoma (GA) are frequently detected at an early stage using endoscopic scr...
