Cellular in vivo imaging can reveal the induction, progression and resolution of nervous system pathology in real-time. In this review, we summarize recent research in the field to illustrate how in vivo imaging has enhanced our understanding of a variety of neurological conditions caused by trauma, degeneration, ischemia or inflammation. Finally, we look ahead and discuss how novel biosensors ...

The ultimate check of the actual dose delivered to a patient in radiotherapy can only be achieved by using in vivo dosimetry. This work reports a pilot study to test the applicability of a thermoluminescent dosimetric system for performing in vivo entrance dose measurements in external photon beam radiotherapy. The measurements demonstrated the value of thermoluminescent dosimetry as a treatmen...

Twenty-four patients of moderate persistent perennial asthma with documented aggravation to severe persistent asthma, during monsoon season in the past two years, were put on specific elimination diet during August and September. The diet was based on results of in-vitro allergy tests for a selected food panel. On specific elimination diet, five patients improved to mild persistent asthma and t...

Inhibitory neurons are known to play a vital role in defining the window for critical period plasticity during development, and it is increasingly apparent that they continue to exert powerful control over experience-dependent cortical plasticity in adulthood. Recent in vivo imaging studies demonstrate that long-term plasticity of inhibitory circuits is manifested at an anatomical level. Change...

An interferometric method for parallel optical spectroscopy in the kilohertz range is reported, as well as its experimental validation in the context of high-speed laser Doppler imaging in vivo. The interferometric approach enables imaging in the low light conditions of a 2 kHz frame rate recording with a complementary metal-oxide semiconductor camera. Observation of mice craniums with near-inf...

Direct visualization of microvasculature provides significant insights in microcirculation and critically impacts the diagnosis and treatment of microcirculatory diseases. Recently, we discovered that the high-energy Soret fluorescence of hemoglobin peaked at 438 nm with an extremely short lifetime becomes strongly visible under two-photon excitation. Based on the distinct spectral and temporal...

The study of the preimplantation mouse embryo has progressed over the past 50 years from descriptive biology through experimental embryology to molecular biology and genetics. Along the way, the molecular pathways that lead to the establishment of the three cell lineages of the blastocyst have become more clearly understood but the fundamental questions of lineage commitment remain the same as ...

To achieve the best therapeutic efficacy and good prognosis, the drugs necessitate tailored profiles of excellent spatiotemporal control and therapeutic monitoring. Here we introduce a programmed theranostic nanoparticle with self-adapting properties for tumor-specific systemic treatment, including stealthy surface to prolong circulation time in blood, surface charge-reversion for tumor targeti...

Intravital ratiometric microscopy is a powerful method for quantitative study of kidney functions. As demonstrated in the examples, both the generalized polarity and direct ratio imaging approaches allow investigators to address basic and important questions such as those related to filtration, permeability and reabsorption. Both approaches have similar advantageous for in vivo imaging. However...
