Single‐molecule localization microscopy is exploited to quantify the number of hemoglobin copies bound to specific receptors on S. aureus wall. This quantification supports the design of a photoactive derivative of hemoglobin able to photo‐inactivate S.

The relationship between the methods for the determination of erythrocyte protoporphyrins (EP) and zinc protoporphyrins (ZPP) [PDF]
U svrhu izbora najprikladnije metode za određivanje eritrocitnog protoporfirina (EP), vrlo važnog biokemijskog pokazatelja u ocjeni povećane apsorpcije olova, ispitan je odnos između spektrofluorometrijske metode Chisolm-Brown i spektrofotometrijske ...

Zn protoporphyrin IX is formed not from heme but from protoporphyrin IX [PDF]
We examined the effects of exogenous myoglobin, a bivalent chelator, and nitrite on Zn protoporphyrin IX (ZPP) formation by using model systems. ZPP was formed in a model solution without addition of exogenous myoglobin. After incubation, the amount of ZPP in a model solution was increased but that of heme was not decreased compared with the amounts ...

Formation of meso, N-diphenylprotoporphyrin IX by an aerobic reaction of phenylhydrazine with oxyhemoglobins. [PDF]
Administration of phenylhydrazine to rabbits resulted in the denaturation of hemoglobins in erythrocytes, causing the formation of intracellular precipitates known as Heinz bodies, severe hemolytic anemia, and reticulocytosis.

An atomically precise Ag6 nanocluster stores multiple electrons through sequential reduction reactions and releases the stored charge through successive emissive oxidation reactions with a benzoyl peroxide‐derived radical. This multielectron charge storage pathway enables an electrochemiluminescence cascade, producing a substantially more efficient ...

Stimuli‐responsive nanostructured hydrogen sulfide donors for enhanced cancer treatments
Three typical kinds of stimuli‐responsive nanostructured hydrogen sulfide (H2S) donors are reviewed. The nanostructures ensure precise delivery of H2S to the lesion site and regulate the release behavior. The H2S‐based gas therapy has been used to synergize with other cancer treatment modalities, achieving enhanced efficacy while reducing side effects.

Nonthermal ultrasound transforms acoustic energy into diverse therapeutic bioeffects through cavitation, mechanical stimulation, and physicochemical activation. This review discusses how acoustic parameters, biological mechanisms, and responsive materials interact to influence nonthermal ultrasound‐enabled cancer therapies. Mechanism‐guided engineering
