Malignant Gastrointestinal Neuroectodermal Tumor: A New Kid on the Block?

J Comput Assist Tomogr 2022 Jun 28. Epub 2022 Jun 28.

From the Department of Abdominal Radiology, The University of Texas MD Anderson Cancer Center.

Abstract: Also referred to as "osteoclast-rich, clear cell sarcoma-like tumor of the gastrointestinal tract (CCSLGT)," malignant gastrointestinal neuroectodermal tumor is a newly described, rare, aggressive sarcoma that commonly arises in the small bowel, stomach, and colon. Histogenesis is likely from an autonomous nervous system-related primitive cell of neural crest origin. The hallmark genetic finding of EWS-CREB1 or EWS-ATF1 fusion transcripts clinches the diagnosis. Read More

Antiallergic Treatment of Bariatric Patients: Potentially Hampered Solubility/Dissolution and Bioavailability of Loratadine, but Not Desloratadine, Post-Bariatric Surgery.

Mol Pharm 2022 Jun 27. Epub 2022 Jun 27.

Department of Clinical Pharmacology, School of Pharmacy, Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer-Sheva 8410501, Israel.

Gastrointestinal anatomical/physiological changes after bariatric surgery influence variables affecting the fate of drugs after ingestion, and medication management of these patients requires a thorough and complex mechanistic analysis. The aim of this research was to study whether loratadine/desloratadine antiallergic treatment of bariatric patients is at risk of being ineffective due to impaired solubility/dissolution. The pH-dependent solubility of loratadine/desloratadine was studied in vitro, as well as ex vivo, in gastric content aspirated from patients before versus after bariatric surgery. Read More

Role of N6-Methyladenosine Methylation Regulators in the Drug Therapy of Digestive System Tumours.

Front Pharmacol 2022 9;13:908079. Epub 2022 Jun 9.

Department of Pharmacy, Taizhou Central Hospital (Taizhou University Hospital), Taizhou, China.

Digestive system tumours, including stomach, colon, esophagus, liver and pancreatic tumours, are serious diseases affecting human health. Although surgical treatment and postoperative chemoradiotherapy effectively improve patient survival, current diagnostic and therapeutic strategies for digestive system tumours lack sensitivity and specificity. Moreover, the tumour's tolerance to drug therapy is enhanced owing to tumour cell heterogeneity. Read More

A novel hypomorphic Apex1 mouse model implicates apurinic-apyrimidinic endonuclease 1 in oxidative DNA damage repair in gastric epithelial cells.

Antioxid Redox Signal 2022 Jun 25. Epub 2022 Jun 25.

University of California San Diego, 8784, Department of Medicine, La Jolla, California, United States;

Aims: While best known for its role in oxidative DNA damage repair, apurinic-apyrimidinic endonuclease-1 (APE1) is a multifunctional protein that regulates multiple host responses during oxidative stress including the reductive activation of transcription factors. As knockout of the APE1-encoding gene, , is embryonically lethal, we sought to create a viable model with generalized inhibition of APE1 expression.

Results: A hypomorphic mouse with decreased APE1 expression throughout the body was generated using a construct containing a cassette knocked into the site. Read More

Influence of food macrostructure on the kinetics of acidification in the pig stomach after the consumption of rice- and wheat-based foods: Implications for starch hydrolysis and starch emptying rate.

Food Chem 2022 Jun 7;394:133410. Epub 2022 Jun 7.

Riddet Institute, Massey University, Private Bag 11222, Palmerston North, New Zealand; Department of Biological and Agricultural Engineering, University of California, Davis, CA 95618, USA. Electronic address:

How the stomach can serve as a biochemical environment for starch digestion and the implications on starch emptying are not well-understood. Biochemical changes during gastric digestion of cooked wheat- and rice-based diets of varying particle size and microstructure were investigated using a growing pig model. In larger-particle size diets (rice grain, rice noodle, pasta), pH >3 was maintained in the proximal stomach digesta even until 240 min digestion, resulting in extended remaining amylase activity and accumulation of maltose from starch hydrolysis in the stomach.

Identification and Quantification of Microplastics in the Marine Environment Using the Laser Direct Infrared (LDIR) Technique.

Environ Sci Technol 2022 Jun 24. Epub 2022 Jun 24.

Aix-Marseille University, Toulon University, CNRS, IRD, M I O, Marseille 13007, France.

Here, we evaluate for the first time the performances of the newly developed laser direct infrared (LDIR) technique and propose an optimization of the initial protocol for marine microplastics (MPs) analysis. Our results show that an 8 μm porosity polycarbonate filter placed on a Kevley slide enables preconcentration and efficient quantification of MPs, as well as polymer and size determination of reference plastic pellets of polypropylene (PP), polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), and polyethylene terephthalate (PET), with recoveries ranging from 80-100% and negligible blank values for particle sizes ranging from 200 to 500 μm. A spiked experiment using seawater, sediment, mussels, and fish stomach samples showed that the method responded linearly with significant slopes ( ranging from 0. Read More
