A novel antibacterial peptide derived from Crocodylus siamensis haemoglobin hydrolysate induces membrane permeabilization causing iron dysregulation, oxidative stress and bacterial death [PDF]
, 2017 Aims A novel antibacterial peptide from Crocodylus siamensis haemoglobin hydrolysate (CHH) was characterized for antimicrobial activity. Methods and Results CHHs were hydrolysed for 2 h (2 h-CHH), 4 h (4h-CHH), 6 h (6 h-CHH) and 8 h (8 h-CHH). The

A Radial Diffusion Assay for Pepsinogen and Pepsin
Gastroenterology, 1969 A radial diffusion assay for the determination of gastric pepsin and uropepsin is developed. Urine, gastric juice, or solutions of hog pepsinogen are allowed to diffuse radially from circular wells in agar gel which contains acid-hemoglobin. After a period of incubation, the undigested hemoglobin is fixed with acid-alcohol, and after drying, the agar ...

A Spectrophotometric Method for the Analysis of Pepsin
Gastroenterology, 1970 p-Nitrophenyl sulfite was found to be a suitable synthetic substrate for rapid spectrophotometric analysis of pepsin in gastric secretion. When this substrate was incubated with enzyme, the maximal rate of change of absorbance at 320 nm was found to be directly proportional to enzyme concentration.

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy
Advanced Materials, EarlyView.Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Role of nitrite, urate and pepsin in the gastroprotective effects of saliva
Redox Biology, 2016 Dietary nitrate is now recognized as an alternative substrate for nitric oxide (•NO) production in the gut. This novel pathway implies the sequential reduction of nitrate to nitrite, •NO and other bioactive nitrogen oxides but the physiological relevance

Advanced Materials, EarlyView.An injectable cold atmospheric plasma‐activated decellularized tumor extracellular matrix hydrogel is introduced as a post‐surgical immunoactivation platform. The engineered gel attracts residual tumor cells and induces immunogenic cell death, reshaping the tumor microenvironment and eliciting systemic antitumor immunity. In combination with checkpoint

Advanced Materials, EarlyView.Controlling the protein corona formation onto carbon nanomaterials (CNMs) enhances their functionalities as platforms for cancer theranostics. Here, we reviewed the effects of the intrinsic and acquired properties of CNMs on protein corona formation, the consequent biological and toxicological outcomes, and the strategies to reshape corona formation ...
