The Amino Acid Composition of the Organic Matrix of Some Recent and Fossil Shells of Some West Coast Species of Mytilus [PDF]

open access: yes, 1962
The organic matrix from each structural unit of Mytilus californianus has a distinctive amino acid composition. Systematic variations in composition occur within the outer prismatic layer and the periostracum.

The Impact of Tenapanor on Body Composition and Blood Pressure in Peritoneal Dialysis Patients: A Pilot Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Instruction Tenapanor potentially affects fluid volume and blood pressure. This study explored its effects on these parameters in patients undergoing peritoneal dialysis (PD). Methods We conducted a single‐arm, prospective observational study that enrolled 10 patients on PD with hyperphosphatemia who were newly initiated on tenapanor.

Nicotinonitrile based dual inhibitors of tubulin and topoisomerase II exhibit potent anticancer activity

open access: yesScientific Reports
A series of 2,4,6-trisubstituted nicotinonitriles, compounds 10–41, was designed as pyridine bridged analogs of combretastatin A4 and evaluated as dual inhibitors of topoisomerase II and tubulin polymerization.

Plant Organic Acids as Natural Inhibitors of Foodborne Pathogens

open access: yesApplied Sciences
Background: Foodborne infections affect approximately 600 million people annually. Simultaneously, many plants contain substances like organic acids, which have antimicrobial activity. The aim of this study was to examine the effects of 21 organic acids,

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
