Background: Sclareol is a phytochemical used in people's diet in Southeast Asia. Objective: To investigate the immunotherapeutic effectiveness of Sclareol against breast cancer by direct intraperitoneal injection. Methods: Sclareol was isolated and purified from Salvia sclarea. Effect of Sclareol on cell growth inhibition was evaluated by MTT assay. Intraperitoneally injected Sclareol effects o...

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...

A dinuclear ruthenium(II) complex Ruazo was designed and synthesized, in which oxidative cyclization of the azo and o-amino group was employed for the detection of hypochlorous acid (HClO) in aqueous solution. The non-emissive Ruazo formed highly luminescent triazole-ruthenium(II) complex in presence of HClO and successfully imaged HClO in living cell and living mouse.

Computer simulations are used to design more hydrated bilayers, formed from amine-modified porphyrin-phospholipids (PoPs). Experiments confirm that the new constructs give rise to bilayers with greater water content. When chelated with manganese, amine-modified PoPs provide improved contrast for magnetic resonance and are safely used for imaging in vivo.

The holy grail of infection biology is to study a pathogen within its natural infectious environment, the living host. Advances in in vivo imaging techniques have begun to introduce the possibility to visualize, in real time, infection progression within a living model. In this review we detail the current advancements and knowledge in multiphoton microscopy and how it can be related to the fie...

In vivo imaging of the mouse retina using visible and near infrared wavelengths does not achieve diffraction-limited resolution due to wavefront aberrations induced by the eye. Considering the pupil size and axial dimension of the eye, it is expected that unaberrated imaging of the retina would have a transverse resolution of 2 microm. Higher-order aberrations in retinal imaging of human can be...
