S U M M A R Y A method has been described for the quantitative assay of lipoprotein lipase activity in post heparin plasma. The conditions of the away were subjected to critical study. The technique described permits the react.ion to proceed in the test tube as a zero order reaction. It is believed that this technique will permit accurate quantitative study of lipoprotein lipase activity in dif...

Optical clearing allows the reduction of light scattering in biological tissue, enabling 3D morphological information to be obtained deep within tissue using techniques such as optical projection tomography and light sheet microscopy. However, the extent of the clearing is dependent on the technique that is used. There is therefore a need for methods to quantify the quality of the clearing proc...

Tissue optical clearing technique shows a great potential for neural imaging with high resolution, especially for connectomics in brain. The passive clarity technique (PACT) is a relative simple clearing method based on incubation, which has a great advantage on tissue transparency, fluorescence preservation and immunostaining compatibility for imaging tissue blocks. However, this method suffer...

INTRODUCTION This study investigated the accuracy of cone-beam computed tomography (CBCT), peripheral quantitative computed tomography (pQCT), spiral computed tomography (SCT), plain (plain digi), and contrast medium-enhanced digital radiographs (contrast digi) in studying root canal morphology. METHODS The root canal anatomy was analyzed in 95 teeth using CBCT, pQCT, SCT, plain digi, and con...

Three-dimensional visualization of intact tissues is now being achieved by turning tissues transparent. CLARITY is a unique tissue clearing technique, which features the use of detergents to remove lipids from fixed tissues to achieve optical transparency. To preserve tissue integrity, an acrylamide-based hydrogel has been proposed to embed the tissue. In this study, we examined the rationale b...

Recently, a bio-electrochemical technique known as CLARITY was reported for three-dimensional phenotype mapping within transparent tissues, allowing clearer whole-body and organ visualization with CB-perfusion (CUBIC) and leading to the development of whole-body clearing and transparency of intact tissues with the PACT (passive clarity technique) and PARS (perfusion-assisted agent release in si...

Background and Aim: Knowledge about the root canal system variations is crucial for successful endodontic treatment. This study aimed to examine the applicability of cone-beam computed tomography (CBCT) as a substitute for the gold-standard tooth clearing technique in identification of internal anatomical variations of mandibular incisors. Materials and Methods: This in-vitro study evaluated 6...
