Diffusion Coefficient Analysis by Dynamic Light Scattering Enables Determination of Critical Micelle Concentration.

The critical micelle concentration is an important property of supramolecular detergents. Two dynamic light scattering approaches have been developed for critical micelle concentration analysis, i. e.

Detergent Chemistry Modulates the Transgression of Planetary Boundaries including Antimicrobial Resistance and Drug Discovery.

Detergent chemistry enables applications in the world today while harming safe operating spaces that humanity needs for survival. Aim of this review is to support a holistic thought process in the design of detergent chemistry. We harness the planetary boundary concept as a framework for literature survey to identify progresses and knowledge gaps in context with detergent chemistry and five planetary boundaries that are currently transgressed, i.

[Palliative symptom control in malignant bowel obstruction due to advanced ovarian cancer].

This case study deals with symptom control of malignant bowel obstruction in patients suffering from recurrent ovarian carcinoma. The objective of the paper is to analyse various options of medical and surgical treatment. Relevant factors which have to be considered when deciding on the most efficient and adequate therapeutical approach are discussed and elaborated on.

Stuttering Reperfusion of Ischemic Myocardium Does Not Exacerbate Myocardial Infarction: Evidence Against Lethal Cell Reperfusion Injury in the Rabbit.

In the clinical setting of acute myocardial infarction, coronary reperfusion may occur intermittently. Whether this intermittent or stuttering reperfusion exacerbates reperfusion cell injury is not known. To investigate whether stuttering reperfusion affects the development of necrosis, anesthetized male rabbits were randomized to either control or stuttering-reperfusion groups.

Acute cocaine administration induces ventricular regional wall motion and ultrastructural abnormalities in an anesthetized rabbit model.

Whether acute doses of cocaine can induce left ventricular (LV) regional wall motion abnormalities in animals with otherwise normal coronary arteries is unknown. We studied rabbits receiving constant cocaine infusions (group I: 0.025 to 1.
