A method of imaging cancer stem cells comprises disposing a population of first ultrasound-switchable fluorophorms having a first switching threshold in the biological environment, the first ultrasound-switchable fluorophores being functionalized for attachment to a first biomarker expressed by the CSCs; disposing a population of second ultrasound-switchable fluorophorms having a second switching threshold in the biological environment, the second ultrasound-switchable fluorophores being functionalized for attachment to a second biomarker expressed by the CSCs; exposing the biological environment to an ultrasound beam to form an activation region; disposing one or more of the first and/or second ultrasound-switchable fluorophores in the activation region to switch the first and/or second fluorophores from an off state to an on state; exciting the first and second ultrasound-switchable fluorophores in the activation region with a beam of electromagnetic radiation; and detecting light emitted by the first and second ultrasound-switchable fluorophores.

The present disclosure relates to a solution comprising a water insoluble carbohydrate and a fluorescent dye, such as a near infrared (NIR) contrast agent, wherein the solution sets under aqueous conditions, such as in vivo, to form e.g. a gel, a glass, a semi-solid, a solid, a crystal or any mixtures thereof. The disclosure further relates to preparation of such solution and use of such solution for in vivo imaging and/or guidance of surgery or interventional therapeutic procedures.

Compounds including a tetrapyrrolic or reduced tetrapyrrolic group/moiety and an epidermal growth factor receptor targeting group are disclosed. For example, a compound includes a tetrapyrrolic or reduced tetrapyrrolic group or moiety, a linker moiety, an epidermal growth factor receptor targeting group, and, optionally, a PET-active functional group. Uses of the compounds, for example, methods of treating a hyperproliferative tissue in an individual, and kits including one or more of the compounds are also provided.

A method of preventing post-operative endophthalmitis involves injecting a colored antibiotic solution into the anterior segment of the eye during surgery, the antibiotic solution having moxifloxacin, cefuroxime, vancomycin, or some combination thereof, and the coloring agent being preferably a cobalamin (e.g., cyanocobalamin).

A medical control device includes: a light source controller configured to control a light source configured to emit excitation light in a first wavelength band and light in a second wavelength band; a captured image acquiring unit configured to acquire a captured image obtained by capturing an image of an observation target irradiated with light emitted from the light source; an evaluation value calculator configured to calculate, based on the captured image, an evaluation value used for at least one of a first control for controlling a focal position of an imaging device configured to generate the captured image or a second control for controlling a brightness of the captured image; an operation controller configured to perform, based on the evaluation value, at least one of the first control or the second control; and an adjustment processing execution unit configured to perform adjustment processing on the captured image.
