Methods, apparatuses, and systems for monitoring health of corneal tissue are disclosed. The system includes a corneal measurement device configured to measure a first state of health indicator that is tissue thickness or volume of a region of the corneal tissue during a first period of time and a second state of health indicator that is tissue thickness or volume of the region during a second period of time after the first period of time. The system further includes a processing unit configured to receive the first and second state of health indicators from the corneal measurement device and generate a health map of the region based on the first and second state of health indicators, the health map indicative of a change between the first and second state of health indicators as measured from the first period of time to the second period of time in the region of the cornea.

CONTINUOUS OPERATION HIGH SPEED ION TRAP MASS SPECTROMETER
The present disclosure discusses a system and method for continuous operation of an ion trap mass spectrometer. The described system does not introduce ions into the ion trap in distinct trapping phase, rather the described system continuously injects ions into the ion trap while continuously scanning out the ions. The system and method described herein achieves a much higher duty cycle and cycle rate when compared to standard mass spectrometer devices.

Abstract
Methods for treating or preventing a Foxp3+ T regulatory cell (Treg) related disease in a subject in need thereof comprise administering to the subject an effective amount of a pharmaceutical composition comprising an inhibitor of a histone/protein acetyltransferase (HAT). Methods for identifying an agent useful for treating or preventing a Foxp3+ T regulatory cell (Treg) related disease comprise (a) contacting a candidate agent with a test sample comprising Foxp3+ T regulatory cells (Tregs), and (b) comparing a function of the Foxp3+ Tregs in the test sample with that in a control sample, wherein inhibition of the function of the Foxp3+ Tregs in the test sample when compared with the control sample indicates that the candidate agent is an agent useful for treating or preventing a Foxp3+ Treg related disease.

N-HYDROXYLSULFONAMIDE DERIVATIVES AS NEW PHYSIOLOGICALLY USEFUL NITROXYL DONORS
The invention relates to N-hydroxysulfonamide derivatives that donate nitroxyl (HNO) under physiological conditions and are useful in treating and/or preventing the onset and/or development of diseases or conditions that are responsive to nitroxyl therapy, including heart failure and ischemia/reperfusion injury. Novel N-hydroxysulfonamide derivatives release NHO at a controlled rate under physiological conditions, and the rate of HNO release is modulated by varying the nature and location of functional groups on the N-hydroxysulfonamide derivatives.
